DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figure 1-3 The utility model provides the following technical solutions: a universal caster with shock-absorbing function, comprising a mounting plate 1, a waist-shaped groove 6 is opened at the corner of the mounting plate 1, a longitudinal shock-absorbing mechanism 5 is arranged at the lower end of the mounting plate 1, a U-shaped frame 3 is arranged at the lower end of the longitudinal shock-absorbing mechanism 5, a lateral shock-absorbing mechanism 2 is arranged on the side of the U-shaped frame 3, and a moving wheel 4 is arranged on the side of the lateral shock-absorbing mechanism 2.

[0021] Specifically, the lateral shock absorbing mechanism 2 includes a connecting plate 21, a shock absorbing assembly 22, a rotating shaft 1 23 and a rotating shaft 24. The connecting plate 21 is arranged on the side of the lower end of the U-shaped frame 3. The lower end of the U-shaped frame 3 is rotatably connected to the connecting plate 21 through the rotating shaft 1 23. The other side of the connecting plate 21 is rotatably connected to the moving wheel 4 through the rotating shaft 24. The shock absorbing assembly 22 is arranged on the other side of the connecting plate 21.

[0022] By adopting the above technical solution, when the moving wheel 4 is moving, since the moving wheel 4 will produce a back and forth shaking problem when moving, the present application document connects the moving wheel 4 to the U-shaped frame 3 through the connecting plate 21, and the lower end of the U-shaped frame 3 is rotationally connected to the connecting plate 21 through the rotating shaft 1 23, and the other side of the connecting plate 21 is rotationally connected to the moving wheel 4 through the rotating shaft 2 24. At this time, it can be ensured that the moving wheel 4 can achieve effective transmission conversion when moving. At the same time, through the setting of the shock-absorbing component 22, the moving wheel 4 can play an effective shock-absorbing work when moving.

[0023] Specifically, the shock absorbing assembly 22 includes a hinge seat 221, a rotating block 222, a damper 223, a buffer spring 224, a hinge seat 225 and a rotating block 226. The other side of the connecting plate 21 is provided with a hinge seat 221, the upper end of the side of the U-shaped frame 3 is provided with a hinge seat 225, the side of the hinge seat 225 is provided with a rotating block 226, the upper end of the hinge seat 221 is provided with a rotating block 222, a damper 223 is connected between the rotating block 222 and the rotating block 226, and the surface of the damper 223 is sleeved with a buffer spring 224.

[0024] By adopting the above technical solution, when the moving wheel 4 moves, if the moving wheel 4 tilts backward, the buffer spring 224 on the surface of the damper 223 will be compressed, and with the action of the damper 223, the rebound of the buffer spring 224 can be suppressed. When the moving wheel 4 moves and tilts forward, the buffer spring 224 will be stretched, and with the action of the damper 223, the rebound of the buffer spring 224 can be suppressed. In summary, the shock-absorbing and buffering effect of the moving wheel 4 in the front and rear lateral positions can be achieved.

[0025] Specifically, the rotating block 222 is rotatably connected to the hinge seat 221 via a rotating shaft, and the hinge seat 225 is rotatably connected to the rotating block 226 via a rotating shaft.

At this time, it can be ensured that the moving wheel 4 can achieve effective transmission conversion when moving. At the same time, through the setting of the shock absorbing component 22, the moving wheel 4 can play an effective shock absorbing role when moving. When the moving wheel 4 moves, if the moving wheel 4 tilts backward, the buffer spring 1 on the surface of the damper 1 223 will be compressed, and with the action of the damper 1 223, the rebound of the buffer spring 1 224 can be suppressed. When the moving wheel 4 tilts forward when moving, the buffer spring 1 224 will be stretched, and with the action of the damper 1 223, the rebound of the buffer spring 1 224 can be suppressed. In summary, the shock absorbing and buffering effect of the moving wheel 4 in the front and rear lateral positions can be achieved.

[0028] Example 2

[0029] The difference between this embodiment and the first embodiment is that the longitudinal damping mechanism 5 comprises a rotating plate 51, a rotating seat 52, a damper 55 and a buffer spring 56.

[0030] By adopting the above technical solution, when the moving wheel 4 moves, the vibrations generated in the up and down directions can be buffered by the buffer spring 2 56 , and the setting of the damper 2 55 can suppress the rebound of the buffer spring 2 56 , thereby achieving the buffering and shock-absorbing effect of the longitudinal position of the moving wheel 4 .

[0031] Specifically, the longitudinal damping mechanism 5 further includes an inner rod 53 and an outer rod 54. The inner rod 53 is disposed on the side of the lower end of the rotating plate 51, and the outer rod 54 is sleeved on the lower end surface of the inner rod 53.

[0032] By adopting the above technical solution, the inner rod 53 will slide inside the outer rod 54, thereby improving the buffering stability of the longitudinal shock absorbing mechanism 5.

[0033] When this embodiment is in use, when the moving wheel 4 moves, the vibrations generated in the up and down directions can be buffered by the buffer spring 2 56. The setting of the damper 2 55 can suppress the rebound of the buffer spring 2 56, thereby achieving the buffering and shock-absorbing effect of the longitudinal position of the moving wheel 4. The inner rod 53 will slide inside the outer rod 54, thereby improving the buffering stability of the longitudinal shock-absorbing mechanism 5.

[0034] Working principle and use process of the utility model: When the utility model is in use, when the moving wheel 4 is walking, since the moving wheel 4 will have the problem of shaking back and forth when moving, the application document connects the moving wheel 4 to the U-shaped frame 3 through the connecting plate 21, and the lower end of the U-shaped frame 3 is rotatably connected to the connecting plate 21 through a rotating shaft 1 23, and the other side of the connecting plate 21 is rotatably connected to the moving wheel 4 through a rotating shaft 24. At this time, it can be ensured that the moving wheel 4 can achieve effective transmission conversion when moving. At the same time, through the setting of the shock absorbing component 22, the moving wheel 4 can play an effective shock absorbing work when moving. When the moving wheel 4 moves, if the moving wheel 4 tilts backward, at this time, the damper 1 223 The buffer spring 224 on the surface will be compressed, and with the action of the damper 223, the rebound of the buffer spring 224 can be suppressed. When the moving wheel 4 moves and tilts forward, the buffer spring 224 will be stretched, and with the action of the damper 223, the rebound of the buffer spring 224 can be suppressed. In summary, the shock-absorbing and buffering effect of the moving wheel 4 in the front and rear lateral positions can be achieved; when the moving wheel 4 moves, the vibrations in the up and down directions can be buffered by the buffer spring 2 56, and with the setting of the damper 2 55, the rebound of the buffer spring 2 56 can be suppressed, thereby achieving the buffering and shock-absorbing effect of the longitudinal position of the moving wheel 4, and the inner rod 53 will slide inside the outer rod 54, thereby improving the buffering stability of the longitudinal shock-absorbing mechanism 5.
