Description

Technical Field

[0001] This utility model belongs to the field of caster bracket technology, specifically relating to an impact-resistant caster bracket. Background Technology

[0002] Currently, most caster brackets on the market adopt a rigid connection structure, that is, the support plate and the mounting base are directly connected by fasteners, and the wheel axle is directly mounted on the mounting base. Although this design is simple in structure, it cannot effectively absorb and disperse impact energy when subjected to impact, resulting in a sudden increase in the contact pressure between the caster and the ground, and even a brief lifting off of the ground, which seriously affects the movement stability and operational safety of the equipment. In view of this, an impact-resistant caster bracket was designed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an impact-resistant caster bracket, which aims to solve to some extent the technical problem that although the existing technology has a simple structure, it cannot effectively absorb and disperse impact energy when subjected to impact, resulting in a sudden increase in the contact pressure between the caster and the ground, and even a brief lifting off of the ground, which seriously affects the movement stability and operational safety of the equipment.

[0004] The technical solution of this utility model is as follows: an impact-resistant caster bracket, comprising a support plate, two mounting seats, a wheel axle, a buffer assembly, and an adjustment assembly, wherein the two mounting seats are symmetrically arranged below the support plate; and the wheel axle is mounted on the two mounting seats.

[0005] The buffer assembly is disposed between the support plate and the mounting base to provide elastic cushioning, and the buffer assembly includes at least one buffer spring.

[0006] The adjustment assembly is disposed between the support plate and the mounting base. The adjustment assembly includes an inclined plate, a fixed shaft, and an adjustment plate. The top end of the inclined plate is connected to the support plate, and the other end of the inclined plate is rotatably connected to the adjustment plate through the fixed shaft. The other end of the adjustment plate is connected to the mounting base through a wheel axle.

[0007] Preferably, the buffer assembly further includes a damping rod located in the middle of the buffer spring.

[0008] Preferably, the top end of the damping rod is fixedly connected to the bottom of the support plate, and the bottom end of the damping rod is fixedly connected to the top of the mounting base.

[0009] Preferably, the system further includes a mounting plate, the bottom of which is fixedly connected to a bearing, and the rotating shaft at the top of the support plate is fixedly inserted into the inner ring of the bearing.

[0010] Preferably, the top of the buffer spring abuts against the bottom of the support plate, and the bottom of the buffer spring abuts against the top of the mounting base.

[0011] Preferably, the mounting plate is provided with multiple fixing holes.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] 1. This impact-resistant caster bracket has a buffer spring between the support plate and the mounting base, and together with the adjustment component, the buffer spring can effectively absorb the impact energy when the caster bracket is impacted. At the same time, the height of the mounting base can be dynamically adjusted by rotating the tilt plate and the adjustment plate to ensure that the caster wheel always maintains close contact with the ground. This solves the problem of unstable contact caused by the rigid connection design in the prior art and improves the smoothness and safety of equipment movement.

[0014] 2. This impact-resistant caster bracket, through the setting of the damping rod, can play a damping role when the caster bracket is impacted, slowing down the compression and rebound speed of the buffer spring, avoiding fatigue damage caused by rapid deformation of the buffer spring, and effectively dispersing the impact energy, reducing the direct impact on the caster wheel.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0023] Please see Figure 1-3 An impact-resistant caster bracket includes a support plate 1, two mounting seats 4, a wheel axle 5, a buffer assembly, and an adjustment assembly. The two mounting seats 4 are symmetrically arranged below the support plate 1; the wheel axle 5 is mounted on the two mounting seats 4.

[0024] A buffer assembly is disposed between the support plate 1 and the mounting base 4 to provide elastic cushioning. The buffer assembly includes at least one buffer spring 3, the top of which abuts against the bottom of the support plate 1 and the bottom of which abuts against the top of the mounting base 4.

[0025] An adjustment assembly is positioned between the support plate 1 and the mounting base 4. The assembly includes an inclined plate 6, a fixed shaft 7, and an adjusting plate 8. The top end of the inclined plate 6 is connected to the support plate 1, and the other end of the inclined plate 6 is rotatably connected to the adjusting plate 8 via the fixed shaft 7. The other end of the adjusting plate 8 is connected to the mounting base 4 via a wheel axle 5. A buffer spring 3 is installed between the support plate 1 and the mounting base 4, working in conjunction with the adjustment assembly. This allows the buffer spring 3 to effectively absorb impact energy when the caster bracket is subjected to impact. Simultaneously, the height of the mounting base 4 is dynamically adjusted by rotating the inclined plate 6 and the adjusting plate 8, ensuring that the caster wheels always maintain close contact with the ground. This solves the problem of unstable contact caused by rigid connection designs in existing technologies, improving the smoothness and safety of equipment movement.

[0026] The buffer assembly also includes a damping rod 2, which is located in the middle of the buffer spring 3. Through the damping rod 2, when the caster bracket is impacted, the damping rod 2 can act as a damper, slowing down the compression and rebound speed of the buffer spring 3, preventing fatigue damage caused by rapid deformation of the buffer spring 3, and effectively dispersing impact energy to reduce direct impact on the caster wheel.

[0027] The top end of the damping rod 2 is fixedly connected to the bottom of the support plate 1, and the bottom end of the damping rod 2 is fixedly connected to the top of the mounting base 4. The damping rod 2 and the buffer spring 3 form a coaxial composite structure, which can achieve a double buffering effect when the caster bracket is impacted.

[0028] The impact-resistant caster bracket also includes a mounting plate 10, with a bearing 9 fixedly connected to the bottom of the mounting plate 10. The outer ring of the bearing 9 is fixedly connected to the bottom of the mounting plate 10, and the pivot at the top of the support plate 1 is fixedly inserted into the inner ring of the bearing 9. When the equipment needs to turn, the support plate 1 can rotate freely around the axis of the bearing 9, driving the lower axle 5 and the caster wheels to turn synchronously.

[0029] The mounting plate 10 has multiple fixing holes, and the caster bracket can be securely installed on the target equipment by bolts or other fasteners.
