Technical Field

[0001] The utility model relates to the technical field of casters, in particular to a shock-absorbing wheel with an aluminum alloy bracket. Background Art

[0002] Mobile casters are a common mechanical component, mainly used for the movement and positioning of various equipment, such as mobile scaffolding, mobile furniture, medical equipment, etc. Their design and working principle are to achieve flexible movement and smooth operation of the equipment.

[0003] After searching, the patent number is CN217574718U, and the name is a utility model of a high-stability mobile caster, including a mounting seat. Through research and analysis, it is found that although the device can avoid breakage and deformation caused by pressure concentrated on one side of the force center when supporting heavier objects, thereby improving the stability of the caster structure, the following disadvantages still exist to a certain extent.

[0004] For example, the overall structure is heavy. Although it can avoid fracture and deformation due to pressure, its strength is low and it will still suffer a certain degree of damage after being impacted. At the same time, there is no shock-absorbing structure, which is prone to severe vibration and high noise when walking on steep roads. In order to solve the above technical problems, we designed an aluminum alloy bracket shock-absorbing wheel. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum alloy bracket shock-absorbing wheel, comprising a fixed shell, an inner cavity of the fixed shell is penetrated by a connecting component, a shock-absorbing component is installed at the bottom of the inner cavity of the fixed shell, the shock-absorbing component comprises an installation cavity and an aluminum alloy bracket, the front side of the aluminum alloy bracket penetrates to the front side of the fixed shell, a connecting shaft is penetrated by the center of the front side of the surface of the aluminum alloy bracket, and the left and right sides of the connecting shaft are fixedly connected to the wheel body.

[0007] Preferably, the connecting assembly comprises a connecting rod, the connecting rod is arranged through the top of the fixed shell, and the bottom of the connecting rod penetrates into the inner cavity of the fixed shell and is fixedly connected with the sliding rod.

[0008] Preferably, a sealing disk is sleeved and installed on the bottom of the connecting rod surface, an arc groove is opened on the bottom of the sliding rod surface, and the inner cavity of the fixed shell is fixedly connected to a limiting guide column at the arc groove.

[0009] Preferably, the installation cavity is opened at the bottom of the inner cavity of the fixing shell, and the rear side of the aluminum alloy bracket is located at the top of the inner cavity of the installation cavity.

[0010] Preferably, a shock-absorbing spring is fixedly connected to the bottom of the inner cavity of the installation cavity, and the top of the shock-absorbing spring is fixedly connected to the bottom of the rear side of the aluminum alloy bracket.

[0011] Preferably, the aluminum alloy bracket is processed by an aluminum extrusion processing technology, and the interior of the aluminum alloy bracket is designed as a hollow structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model utilizes the aluminum extrusion processing technology to process the aluminum alloy bracket and performs a hollowing treatment on it, which has the effect of reducing weight. The strength of aluminum is better than that of plastic, and the thickness can be made thin enough, thereby reducing the thickness and the wheelbase between the two wheels, making the steering more flexible. At the same time, the shock-absorbing spring can be used for buffering, reducing the vibration during movement and reducing noise. The overall processing cost is low, and the practicality of the caster is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] See also Figure 1-Figure 4 , an aluminum alloy bracket shock-absorbing wheel, comprising a fixed shell 1, a connecting component 2 is installed through the inner cavity of the fixed shell 1, a shock-absorbing component 5 is installed at the bottom of the inner cavity of the fixed shell 1, the shock-absorbing component 5 comprises a mounting cavity 51 and an aluminum alloy bracket 53, the front side of the aluminum alloy bracket 53 penetrates to the front side of the fixed shell 1, a connecting shaft 4 is installed through the center of the front side of the surface of the aluminum alloy bracket 53, and the left and right sides of the connecting shaft 4 are fixedly connected to the wheel body 3;

[0020] See also Figure 1 , Figure 3 and Figure 4 The connecting assembly 2 includes a connecting rod 21, which is disposed through the top of the fixed shell 1, and the bottom of the connecting rod 21 passes through the inner cavity of the fixed shell 1 and is fixedly connected with a sliding rod 22;

[0021] See also Figure 1 , Figure 3 and Figure 4 The bottom of the surface of the connecting rod 21 is sleeved with a sealing disk 25, and the bottom of the surface of the sliding rod 22 is provided with an arc groove 23. The inner wall of the arc groove 23 is in sliding contact with the surface of the limiting guide pillar 24. This design can make the sliding rod 22 rotate more smoothly on the surface of the limiting guide pillar 24, and can play a limiting effect to prevent the sliding rod 22 from falling off from the inside of the fixed shell 1. The inner cavity of the fixed shell 1 is located at the arc groove 23 and is fixedly connected to the limiting guide pillar 24;

[0022] See also Figure 3 and Figure 4 The installation cavity 51 is opened at the bottom of the inner cavity of the fixed shell 1, and the rear side of the aluminum alloy bracket 53 is located at the top of the inner cavity of the installation cavity 51;

[0023] See also Figure 3 and Figure 4 A shock absorbing spring 52 is fixedly connected to the bottom of the inner cavity of the installation cavity 51. By setting the shock absorbing spring 52, a shock absorbing effect can be achieved to buffer the vibration of the aluminum alloy bracket 53, thereby reducing noise. The top of the shock absorbing spring 52 is fixedly connected to the bottom of the rear side of the aluminum alloy bracket 53;

[0024] See also Figure 3 and Figure 4 The aluminum alloy bracket 53 is processed by an aluminum extrusion processing technology, and the interior of the aluminum alloy bracket 53 is a hollow structure design.

[0025] When in use, the device is installed on the bottom of the required installation equipment through the connecting rod 21, and the wheel body 3 contacts the ground to move. During the movement, the sliding rod 22 rotates inside the fixed shell 1, so that the wheel body 3 can move in different directions. During the movement, the limiting guide column 24 slides and limits inside the arc groove 23 to prevent the fixed shell 1 from separating from the sliding rod 22. When the wheel body 3 is bumped, the vibration is transmitted to the connecting shaft 4 and continues to be transmitted to the aluminum alloy bracket 53. The vibration behind the aluminum alloy bracket 53 is transmitted to the shock-absorbing spring 52, and the shock-absorbing spring 52 is deformed to buffer the vibration to achieve a shock-absorbing effect.

[0026] To sum up: the aluminum alloy bracket shock-absorbing wheel, through the cooperation of the fixed shell 1, the connecting component 2, the wheel body 3, the connecting shaft 4 and the shock-absorbing component 5, solves the problems of heavy weight and low strength of the overall structure, no shock-absorbing structure, and easy to vibrate violently and make loud noise when walking on steep roads.
