Description

Technical Field

[0001] This utility model relates to the field of caster technology, specifically to a stainless steel shock-absorbing caster. Background Technology

[0002] Casters are widely used to facilitate the movement of objects. In traditional caster structures, the plate connecting and fixing the caster is usually directly welded or riveted to the bearing structure by upper and lower fixing parts to achieve "omnidirectional" rotation. Currently, there is a type of caster mainly designed for the delivery of heavier products. Due to the special operating environment, the casters are subjected to greater pressure and more frequent wear. Because the casters work under high pressure for a long time, the "omnidirectional" structure of the caster is easily damaged. Moreover, because it cannot be disassembled, once damaged, it cannot be repaired, resulting in a short product lifespan, which shows that this design is not ideal. In addition, during the delivery of goods, this type of caster is subjected to not only vertical pressure but also significant friction from the ground and goods during transportation. This results in greater pressure on the axle during movement, making it more prone to damage. Therefore, its structure is also not ideal and needs further improvement. Utility Model Content

[0003] The purpose of this utility model is to provide a stainless steel shock-absorbing caster to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a stainless steel shock-absorbing caster, comprising a roller 1 and a caster bracket 13, characterized in that: the upper end of the caster bracket 13 is connected to a support frame 6 via a connecting shaft 12, and the front end of the support frame 6 is provided with a second hinge hole 5, and the lower middle end of the caster bracket 13 is provided with a first hinge hole 2, and the two ends of the shock-absorbing cylinder 4 are respectively hinged to the second hinge hole 5 and the first hinge hole 2.

[0005] Furthermore, the shock-absorbing cylinder 4 is also equipped with a compression spring 3.

[0006] Furthermore, the rear end of the support frame 6 is provided with a groove 7, and a connecting block 9 is installed in the groove 7 and connected by a rotating shaft 8.

[0007] Furthermore, the support frame 6 has a mounting groove 11 for mounting the caster bracket 13 at its rear end, and is connected by a pin.

[0008] Furthermore, the connecting block 9 is provided with at least two connecting slots 10.

[0009] This utility model has the following advantages: First, the shock absorption mechanism is located on the inclined side, which increases the shock absorption distance and effect; second, it has a double-layer shock absorption mechanism with spring and shock absorption cylinder, which makes the shock absorption effect better; third, the structure is simpler, which is more conducive to production and processing and reduces production costs.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 This utility model provides a technical solution: a stainless steel shock-absorbing caster, including a roller 1 and a caster bracket 13, with the roller 1 located below the caster bracket 13.

[0014] The upper end of the caster bracket 13 is connected to the support frame 6 via a connecting shaft 12. The lower rear end of the support frame 6 is provided with a mounting groove 11 for mounting the caster bracket 13, and is connected by a pin to allow it to rotate. At the same time, the front end of the support frame 6 is provided with a second hinge hole 5, and the lower middle end of the caster bracket 13 is provided with a first hinge hole 2. The two ends of the shock-absorbing cylinder 4 are hinged to the second hinge hole 5 and the first hinge hole 2, respectively. The shock-absorbing cylinder 4 is also provided with a compression spring 3 to achieve a double-layer shock absorption effect and improve shock absorption efficiency. At the same time, because of the inclined shock absorption mechanism, the shock absorption distance is larger and the application range is wider.

[0015] The rear end of the support frame 6 is provided with a groove 7, and a connecting block 9 is installed in the groove 7 and connected by a rotating shaft 8. The connecting block 9 is provided with at least two connecting slots 10, so that the support frame 6 can rotate with the roller 1.
