Description

CROSS REFERENCE

This application claims the priority of Chinese Patent Application No. 201610234432.8, entitled “Packing boxes of liquid crystal panels”, filed on Apr. 15, 2016, the disclosure of which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates liquid crystal display technology field, and more particularly to a packing box of liquid crystal panels.

BACKGROUND OF THE INVENTION

Generally, the manufacturing process of the liquid crystal devices (LCDs) relates to assemble the components, such as a glass panel, a main control circuit, and a housing. The above components are manufactured and package first, and are assembled in subsequent manufacturing processes. After the liquid crystal panel is manufactured and is packaged within the packing box, the packing box is transported to corresponding assembly factory.

The packing material of the box includes an outer paper box and an internal packing box. Usually, the packing boxes are stacked together. To enhance the assembly time, the directions of the packing boxes have to be the same. However, such stacking configuration may result in that operators may not be able to recognize the directions, which slows down the packing speed.

SUMMARY OF THE INVENTION

The present disclosure relates to a packing box of liquid crystal panels to enhance the packing speed.

In one aspect, apacking box of liquid crystal panels includes: an outer body and two bearing trays received within the outer body, each of the bearing trays includes a body and a plurality of clips arranged periodically, the body includes a first surface and a second surface back to the first surface, the clip protrudes from the first surface toward the second surface, the clip includes a recess portion on a top portion of the first surface and a protrusion portion on the second surface, a hub is arranged on a bottom of the recess portion, the hub extends toward an internal of the protrusion portion, when the two bearing trays are stacked, the protrusion portion of the bearing trays on a top layer inserts into the hub of the other bearing tray to abut against a wall of the hub.

Wherein cross sections of the hub and the clip are crisscross-shaped or equilateral-triangular.

Wherein the body and the clips are integrally formed by injection molding.

Wherein the hub and the protrusion portion are conical columns.

Wherein a plurality of positioning slots are arranged on the first surface of each of the bearing tray, and the clips are configured to surround the positioning slots.

Wherein a wall is arranged around a rim of the second surface of each of the bearing trays, when the two bearing trays are stacked, the wall of the bearing tray on the top layer covers the rim of the bearing tray on a down layer.

Wherein the bearing tray is made by mixing plastic material and organic material.

Wherein the clips are uniformly arranged in a rim of the body.

In view of the above, the hub of the bearing tray inserts to the internal of the protrusion. When the two bearing trays are stacked, the protrusion portion of the bearing trays on the top layer inserts into the hub of the other bearing tray to abut against a wall of the hub, which increases the stability therebetween. In addition, the cross sections of the hub and the clip are of symmetrical shapes, such as crisscross-shaped or equilateral-triangular. Due to the symmetrical shape, the hubs may engage with the protrusion portion easily, which saves the packing time.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Embodiments of the present invention are described in detail with the technical matters, structural features, achieved objects, and effects with reference to the accompanying drawings as follows. It is clear that the described embodiments are part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments to those of ordinary skill in the premise of no creative efforts obtained, should be considered within the scope of protection of the present invention.

Referring to FIGS. 1, 2 and 3, the packing box of liquid crystal panels is configured for carrying the liquid crystal panel. Specifically, before the liquid crystal panel, modules, and the housing are assembled to be the LCD, the liquid crystal panel is transported to the assembly lines. During the transportation, the liquid crystal panel has to be prevented from being damaged. In addition, in order to facilitate the unpacking of the liquid crystal panel, the bearing tray is adopted. The packing box includes an outer body (not shown) and two bearing trays 10 received within the outer body. Each of the bearing trays 10 includes a body 11 and a plurality of clips 12 arranged periodically. The body 11 includes a first surface 111 and a second surface 112 back to the first surface 111. The clip 12 protrudes from the first surface 111 toward the second surface 112. In addition, the clip 12 includes a recess portion 121 on a top portion of the first surface 111 and a protrusion portion 122 on the second surface 112. A hub 123 is arranged on a bottom of the recess portion 121. The hub 123 extends toward an internal of the protrusion portion 122. The two bearing trays 10 are stacked. The protrusion portion 122 of the bearing trays 10 on the top layer inserts into the hub 123 of the other bearing tray 10 and abuts against the wall of the hub 123. That is, the recess portion 121 engages with the hub 123.

In the embodiment, the bearing tray 10 is of rectangular plate, and is formed by injection molding. The body 11 and the clips 12 are integrally formed such that the clip 12 is of hollow cylinder. The recess portion 121 is arranged on the top portion of the first surface 111, and the protrusion portion 122 is arranged on the second surface 112. The bearing tray 10 is made by mixing plastic material and organic material so as to enhance the plastic-absorption capability.

Referring to FIG. 3, the clips 12 are arranged in a rim of the body, and may be arranged in anuniform distribution or in a configuration in accordance with the carried weight to effectively support the bearing tray 10. In addition, the locations of the clip 12 may be configured in accordance with the weight to be carried by the bearing tray 10. The hub 123 and the protrusion portion 122 are conical columns. When the two bearing tray 10 are stacked, the protrusion portion 122 of the bearing tray 10 on the top layer may insert into the hub 123. The outside of the protrusion portion 122 abuts against the inside of the hub 123. As such, the protrusion portion 122 of the bearing tray 10 may not abut against the first surface of the bearing tray on the down layer. In addition, the outside of the protrusion portion 122 partially overlaps with the inside of the hub 123, which increases the stability therebetween.

Further, the cross sections of the hub 123 and the clip 12 are of symmetrical shapes, such as crisscross-shaped or equilateral-triangular. Due to the symmetrical shape, when the bearing trays are stacked, the directions of the bearing tray may be ignored when the number and the locations of the clips are the same, which reduces the packing time.

Further, a plurality of positioning slots 13 are arranged on the first surface 111 of each of the bearing tray 10. The clips 12 are configured to surround the positioning slots 13. In the embodiment, a wall 113 is arranged around a rim of the second surface 112 of each of the bearing trays 10. When the two bearing trays 10 are stacked, the wall 113 of the bearing tray 10 on the top layer covers the rim of the bearing tray 10 on the down layer.

Above are embodiments of the present invention, which does not limit the scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit and principles of the embodiment described above should be covered by the protected scope of the invention.
