Description

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention relates to vibration-proof devices for an air compressor, and particularly to a vibration and displacement-proof air compressor, wherein the bottom plate of the air compressor has at least one elastic leg pad made of rubber or a metal spring for preventing the air compressor from displacement.

[0003] (b) Description of the Prior Art

[0004] When actuating an air compressor, the air compressor will vibrate greatly due to the operation of internal components so that the whole machine will vibrate. Thereby, the use of the air compressor is not convenient. Especially, when the air compressor is placed upon the rear cover of a car engine or other higher place. As the air compressor actuates, it is easy to fall down and thus is destroyed.

SUMMARY OF THE INVENTION

[0005] Accordingly, the primary object of the present invention is to provide a vibration and displacement-proof air compressor, wherein the bottom plate of the air compressor is installed with at least one elastic leg pad for absorbing vibration of the elastic leg pad as the air compressor is actuated so as to achieve the object of avoiding the displacement of the air compressor.

[0006] Another object of the present invention is to provide a vibration and displacement-proof air compressor, wherein the the elastic leg pad is made of rubber or metal spring so as to lower the cost.

[0007] A further object of the present invention is to provide a vibration and displacement-proof air compressor, wherein the elastic leg pad is assembled to the bottom plate of the air compressor at a predetermined position.

[0008] A further object of the present invention is to provide a vibration and displacement-proof air compressor, wherein the bottom plate of the air compressor has at least one auxiliary support leg so that the elastic leg pad has a preferred balance effect.

[0009] To achieve the object, the present invention provides a vibration and displacement-proof air compressor has an air compressor. A bottom plate of the air compressor is installed with at least one elastic leg pad. An upper portion of the elastic leg pad is firmly secured to the bottom plate of the air compressor so that when actuating the air compressor, the elastic leg pad absorbs the vibration of the air compressor so that no displacement occurs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Referring to FIGS. 1 and 2, the vibration and displacement-proof air compressor of the present invention is illustrated. The vibration and displacement-proof air compressor includes an air compressor 1 or 1a and at least one elastic leg pad 2 or 2a.

[0021] The air compressor 1 is identical to the prior art air compressor. An electromotive air inflation device is installed in the air compressor 1. An external of the air compressor 1 is installed with a pressure indicator 11 or 11a or an illuminator 12a, and other devices for air inflation. The type of the air compressor 1 is not confined in the present invention, it only needs that the air compressor 1 is suitable to be installed in a car. The elastic leg pad 2 or 2s is made of rubber material. The shape of the elastic leg pad 2 is not confined, such as rectangular shapes, oblong shapes, round shapes, elliptical shapes or other regular or irregular shapes). The elastic leg pad 2 may have a solid structure or a hollow structure. However, the upper portion 21 or 21a thereof is firmly secured to a bottom plate 13 of the air compressor 1. The way for fixing is not confined in the present invention by for example locking, embedding or gluing. The elastic leg pad 2 or 2a is secured to a bottom plate 13 of the air compressor 1 at a predetermined position (such the embodiments illustrated in FIGS. 3 to 5). If necessary, the predetermined position at the bottom plate of the air compressor 1 is added with prior art auxiliary support leg 14 (see FIG. 6). The auxiliary support leg 14 may be made of elastic material. The elastic leg pad 2 or 2a is formed as a fulcrum to have a preferred balance effect.

[0022] Above said at least one elastic leg pad 2 or 2a is installed in the bottom plate 13 of the air compressor 1. When actuating the air compressor 1, the elastic leg pad 2 or 2a will absorb the vibration from the air compressor 1 to fix the air compressor 1 in position. Thereby, the air compressor 1 will not displace. The auxiliary support leg 14 serves to enhance the balance as the air compressor 1 stands. Thereby, the air compressor 1 will not tilt.

[0023] With reference to FIGS. 7 and 8, a hollow elastic leg pad 2 or 2a, and the bottom plate 13 of the auxiliary support leg 14 are assembled. The upper portion 21 or 21a of the elastic leg pad 2 or 2a are installed with respectively buckling groove 211 or 211a. The bottom plate of the air compressor 1 is formed with corresponding embedding holes 131 so that the elastic leg pad 2 or 2a can be embedded into the bottom plate 13 of the air compressor 1. Moreover, a lower portion 22 or 22a of the elastic leg pad 2 or 2a has a shape which is not confined. As shown in the drawings, the lower portion 22 or 22a has a plurality of rings so as to enhance the vibration absorption ability of the elastic leg pad 2 or 2a.

[0024] Referring to FIG. 9, an assembled form of the elastic leg pad 2a and the bottom plate 13 of the air compressor 1 is shown. The upper portion 21a of the elastic leg pad 2 is installed with an engaging piece 212a. The bottom plate 13 of the air compressor 1 is formed with respective embedding holes 132. Thereby, the elastic leg pad 2a can be embedded into and firmly secured to the bottom plate 13 of the air compressor 1.

[0025] With reference to FIG. 10, an way for engaging the elastic leg pad 2a and the bottom plate 13 of the air compressor 1 is illustrated. In that, a screw element 14 is used to lock the elastic leg pad 2a to the bottom plate 13 of the air compressor 1.

[0026] Likewise, in the present invention, the elastic leg pad 2 of the bottom plate 13 of an air compressor may be replaced by a metal spring 3 or 3a (see FIGS. 11 and 12). The metal spring 3 or 3a may have the tapered for,m shown in FIG. 11 or a straight spring with each circle having the same diameter, or the other form with each circle having a diameter which is not confined. However, one end of the metal spring 3 or 3a is attached to a corresponding embedding hole 132 of the bottom plate 13 of the air compressor 1. Thereby, it not only has a preferred vibration absorption effect and the assembled work can be done easily with a lower cost.

[0027] The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
