Description

CROSS REFERENCE TO RELATED APPLICATION

This Non-provisional application claims priority under 35 U.S.C. § 119(a) to Chinese Patent Application No. 202222117251.0, filed on 11 Aug. 2022, the entire contents of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The disclosure relates to the technical field of telescopic structures, in particular to a telescopic rod and a tent structure.

BACKGROUND ART

A telescopic rod is a kind of rod which can be stretched and retracted, which has an advantage of easy storage and has been widely used in tents, photographic devices and cleaning devices.

In order to lock the telescopic rod conveniently, an external screw is adopted in the related telescopic rods, which may result in poor surface smoothness of the telescopic rods. A household telescopic rod is disclosed in Chinese Utility Patent No.: CN206221451U issued on Jun. 6, 2017, which includes an inner pipe and an outer pipe telescopically sleeved together, a telescoping and locking structure, and cuffs respectively sleeved on outer ends of the inner pipe and the outer pipe. The telescoping and locking structure include a linkage shaft with an eccentric wheel, an inner pipe sleeve, a supporting spring and an open meson lock. When the linkage shaft is driven to rotate by the inner pipe, the eccentric wheel is caused to spread the meson lock outward to lock the outer pipe. In locking, the telescopic rod can be locked only by rotating a small angle, instead of having to rotate many times for slipping. In unlocking, the eccentric wheel may not continue to spreading the meson lock outward simply by rotating the inner pipe reversely by a small angle, so that the meson lock can be unlocked after being reset, and then the inner pipe that continues to rotating can drive the meson lock to rotate idle in the outer pipe through a linkage boss, instead of locking the telescopic rod reversely, and thus the telescopic rod can be quickly locked and unlocked only by rotating by a small angle each time, and surface smoothness of the household telescopic rod is good at the same time, but the household telescopic rod includes the linkage shaft with the eccentric wheel, the inner pipe sleeve, the supporting spring and the open meson lock, which results in high structural complexity.

Embodiment 1

With reference to FIGS. 1 to 3, a telescopic rod is provided in this embodiment, which includes a first rod 1, a second rod 2, an eccentric assembly 3, a connector 4 and an eccentric wheel 5.

The second rod 2 is movably sleeved outside the first rod 1.

The eccentric assembly 3 is connected with the first rod 1.

The connector 4 is threadedly connected with the eccentric assembly 3.

The eccentric wheel 5 is threadedly connected with the connector 4, and the eccentric wheel 5 is movably sleeved in the second rod 2.

Specifically, in telescoping, the first rod 1 moves axially, and the first rod 1 drives the eccentric assembly 3, the connector 4 and the eccentric wheel 5 to move axially. In locking, the first rod 1 is rotated circumferentially, and the first rod 1 drives the eccentric assembly 3 to rotate circumferentially. Because the connector 4, the eccentric assembly 3 and the eccentric wheel 5 are all threadedly connected with each other, both the connector 4 and the eccentric wheel 5 rotate asynchronously with the eccentric assembly 3, so that the eccentric wheel 5 and the first rod 1 are contacted with an inner wall of the second rod 2, thus achieving locking effect. In unlocking, it can be realized only by rotating the first rod 1 circumferentially in an opposite direction. It should be noted that since the eccentric wheel 5 is not threadedly connected with the connector 4 too tightly, and a distance between the eccentric wheel 5 and the inner wall of the second rod 2 and a distance between the first rod 1 and the inner wall of the second rod 2 are relatively small, the locking can be realized only by slightly rotating the first rod 1 circumferentially. In other words, following situation may not occur: when the first rod 1 is rotated circumferentially, the first rod 1 drives the eccentric assembly 3, the connecting member 4 and the eccentric wheel 5 to rotate synchronously, so that both the eccentric wheel 5 and the first rod 1 can never be contacted with the inner wall of the second rod 2, that is, locking can never be realized.

Both the first rod 1 and the second rod 2 are tubular members or rod-shaped members with a through groove, which is convenient for the first rod 1 to receive the eccentric assembly 3, the connector 4, etc., and for the second rod 2 to receive the first rod 1. As the second rod 2 is movably sleeved outside the first rod 1, it is convenient for the first rod 1 and the second rod 2 to move axially, thus facilitating telescoping of the telescopic rod 7. The eccentric assembly 3 is supported by the first rod 1 and configured to drive the connector 4 to move. The eccentric assembly 3 can be an eccentric wheel-shaped member, an eccentric disk-shaped member, etc. The connector 4 is configured to drive the eccentric wheel 5 to rotate. The connector 4 can be a bolt, a screw and the like. The eccentric wheel 5 is configured to be contacted with an inner wall of the second rod 2. To sum up, the telescopic rod 7 can be locked and unlocked only with the eccentric assembly 3, the connector 4 and the eccentric wheel 5, without additional elastic member, so that low complexity of the telescopic rod 7 can be ensured for the telescopic rod 7 on a premise of realizing telescoping and locking. A cross section of the eccentric wheel 5 can be circular, elliptical, etc. It should be noted that when the cross section of the eccentric wheel 5 is circular, a rotation center of the eccentric wheel 5 does not coincide with a center of the eccentric wheel 5.

Furthermore, the eccentric assembly 3 includes a the first wheel 31 and a second wheel body 32 which are integrally formed, the first wheel 31 is sleeved in the first rod 1, the second wheel body 32 is connected with an end of the first rod 1, and both the first wheel 31 and the second wheel body 32 are threadedly connected with the connector 4.

Specifically, because the first wheel 31 is located in the first rod 1, and the second wheel body 32 is connected with the end of the first rod 1, the eccentric assembly 3 and the first rod 1 are limitedly sleeved, which functions in axial and radial limiting on both of them. As the first wheel 31 and the second wheel body 32 are integrally formed, a number of parts can be facilitated to be reduced and the low complexity of the telescopic rod 7 can be further ensured. Cross sections of the first wheel 31 and the second wheel body 32 may be circular, oval, etc.

Furthermore, the first wheel 31 is provided with a first threaded hole 311, and the second wheel 32 is provided with a second threaded hole 321 communicating with the first threaded hole 311. Both the first threaded hole 311 and the second threaded hole 321 are matched with the connector 4.

Specifically, both the first threaded hole 311 and the second threaded hole 321 function in effective radial limiting on the connector 4.

Further, the eccentric wheel 5 is provided with a plurality of protrusions 6.

Specifically, the protrusion 6 is supported by the eccentric wheel 5 and configured to increase surface roughness of the eccentric wheel 5, thereby increasing friction between the eccentric wheel 5 and the inner wall of the second rod 2 and ensuring the locking performance Cross section of the protrusion 6 can be fan-shaped, rectangular, trapezoidal or the like.

Further, the eccentric wheel 5 is internally provided with a third threaded hole 51, and the third threaded hole 51 is matched with the connector 4.

Specifically, the third threaded hole 51 functions in effective radial limiting on the connector 4.

Further, the connector 4 includes a connecting member 41 and a limiting member 42.

The connecting member 41 is threadedly connected with both the eccentric assembly 3 and the eccentric wheel 5.

The limiting member 42 is connected with the connecting member 41, and the limiting member 42 is in contact with an end of the eccentric wheel 5 away from the eccentric assembly 3.

Specifically, the connecting member 41 is configured to connecting the eccentric assembly 3 and the eccentric wheel 5. The limiting member 42 is supported by the connecting member 41, and is configured to effectively limit the eccentric wheel 5, thus functioning in effective axial limiting on the eccentric assembly 3. The connector 4 composed of the connecting member 41 and the limiting member 42 can specifically be a bolt, a screw, etc., so that the connector 4 has good application convenience and low application fault tolerance rate, and further reduces complexity of the telescopic rod 7.

Further, the telescopic rod further includes a rivet assembly. The eccentric assembly 3 is provided with a first radial hole 33, the first rod 1 is provided with a second radial hole communicating with the first radial hole 33, and the rivet assembly is matched with both the first radial hole 33 and the second radial hole.

Specifically, the first radial hole 33 and the second radial hole both function in effective radial limiting on the rivet assembly. The rivet assembly provides rivet connection between the eccentric assembly 3 and the first rod 1, which provides them good impact resistance and shock resistance. The rivet assembly can be a semi-circular rivet assembly, a flat-headed rivet assembly, etc.
