Description

Technical Field

[0001] This utility model relates to the field of caster technology, specifically to a silent caster. Background Technology

[0002] Casters include swivel casters, fixed casters, and swivel casters with brakes. Swivel casters, also known as universal wheels, allow 360-degree rotation. Fixed casters, also called directional casters, do not have a rotating structure and cannot turn. Usually, the two types of casters are used together. For example, a handcart has two directional wheels at the front and two swivel wheels near the push handle at the back. Casters are made of various materials, such as PP casters, PVC casters, PU casters, cast iron casters, nylon casters, and TPR casters.

[0003] When using tools such as flatbed carts in spaces requiring a quiet environment, such as hotels and precision instrument manufacturing workshops, the contact surface between the casters and the ground is usually made of metal, which generates considerable noise when rolling on the ground. Furthermore, the existing technology only uses spring shock absorbers on the casters, which is insufficient to reduce vibration and noise. Therefore, this utility model provides a silent caster. Utility Model Content

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the shock absorption structure includes a first rubber shock absorber disposed in the mounting housing, a second rubber shock absorber disposed below the first rubber shock absorber, and a first fastening bolt and a second fastening bolt respectively disposed on both sides of the first rubber shock absorber and the second rubber shock absorber.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the first rubber shock absorber is located close to the carbon steel base, and the second rubber shock absorber is located at the connection between the support leg and the mounting housing.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: wheel discs are provided on both sides of the wheel hub, and a third fastening bolt is provided between the wheel disc and the support leg; the wheel hub is provided with a polyurethane tread.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the top surface of the carbon steel base is provided with mounting holes.

[0010] The beneficial effects of this utility model are as follows: In this utility model, a first rubber shock absorber and a second rubber shock absorber are provided in the mounting housing of the silent caster. The first rubber shock absorber is close to the carbon steel base, and the second rubber shock absorber is located at the connection position between the support leg and the mounting housing. Through the synergistic effect of the dual shock absorption structure, the vibration generated by the caster during movement can be significantly absorbed and buffered, reducing the noise caused by the vibration and achieving a good silent effect.

[0011] Figure 1 This is a side view of the present invention; Figure 2 This is a front view of the present invention; Figure 3 This is a top view of the present invention. Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0013] See attached diagram. Figures 1 to 3 A silent caster in this embodiment includes a carbon steel base 1, a mounting housing 2 fixedly mounted on the bottom of the carbon steel base 1, and a shock-absorbing structure inside the mounting housing 2; support legs 5 are also provided on both sides of the mounting housing 2, and wheel hubs 6 are provided on the support legs 5.

[0014] Preferably, the shock absorption structure includes a first rubber shock absorber 3 disposed in the mounting housing 2, a second rubber shock absorber 4 disposed below the first rubber shock absorber 3, and a first fastening bolt 20 and a second fastening bolt 21 disposed on both sides of the first rubber shock absorber 3 and the second rubber shock absorber 4, respectively.

[0015] Preferably, the first rubber shock absorber 3 is positioned close to the carbon steel base 1, and the second rubber shock absorber 4 is positioned at the connection point between the support leg 5 and the mounting housing 2.

[0016] Preferably, wheel hub 6 is provided with wheel discs 60 on both sides, and a third fastening bolt 50 is provided between the wheel discs 60 and the support leg 5; the wheel hub 6 is provided with polyurethane tread 61.

[0017] Preferably, the top surface of the carbon steel base 1 is provided with mounting holes 10.

[0018] In this embodiment, the caster uses a carbon steel base 1, which provides stable support for the caster and effectively improves the load-bearing capacity of the caster. The mounting housing 2 is equipped with a first rubber shock absorber 3 and a second rubber shock absorber 4. The first rubber shock absorber 3 is close to the carbon steel base 1, and the second rubber shock absorber 4 is located at the connection between the support leg 5 and the mounting housing 2. Through the synergistic effect of the dual shock absorption structure, the vibration generated by the caster during movement can be significantly absorbed and buffered, reducing the noise caused by vibration and achieving a good quiet effect. At the same time, the setting of the first fastening bolt 20 and the second fastening bolt 21 can ensure that the shock absorber is firmly installed and ensure the stable performance of the shock absorption function. Specifically, both the first rubber shock absorber 3 and the second rubber shock absorber 4 are made of high-elasticity rubber material, which has good shock absorption, noise reduction and buffering performance. Compared with traditional spring shock absorbers, rubber shock absorbers are more sensitive to the buffering of weight changes and can play a shock absorption role with very small weight changes. Spring shock absorbers, on the other hand, need to withstand a certain weight before they can start to absorb shocks because of the long spring length and the large force transmission distance. The wheel discs 60 on both sides of the wheel hub 6 are connected to the outriggers 5 by the third fastening bolts 50, making the connection between the wheel hub 6 and the outriggers 5 more stable and reliable; the polyurethane tread 61 on the wheel hub 6 is wear-resistant and elastic, which can not only extend the service life of the caster, but also further reduce the noise generated when it comes into contact with the ground during movement, thus enhancing the quietness effect. The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
