Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casters, in particular to a self-rivet silent caster. Background Art
[0002] Casters are a general term that includes both movable and fixed casters. Movable casters, also known as swivel wheels, have a structure that allows 360-degree rotation. Fixed casters, also known as fixed casters, lack a swivel mechanism and cannot rotate. Commonly used casters typically use an axle to secure the wheel to a bracket. The hub is typically made of two parts that are drilled and then bolted together. The disadvantages of this design are: 1. The bolting requires manual labor, resulting in low efficiency and high production costs; 2. After tightening, gaps appear in some parts of the hub, causing noise during use. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a self-rivet silent caster.
[0004] In order to solve the above problems, the present invention adopts the following technical solutions.
[0005] A self-riveting silent caster includes a first hub and a second hub. The first hub and the second hub are self-riveted to form a hub assembly. The first hub and the second hub are provided with a hole and a protrusion on opposite sides. The protrusion is located in the hole and the edge of the protrusion is provided with a flange to enable the first hub and the second hub to be self-riveted.
[0006] As a further improvement of the present invention, it further comprises a rotating shaft and a bearing, wherein the bearing is arranged in the wheel hub assembly, and the bearing sleeve is arranged on the outside of the rotating shaft.
[0007] As a further improvement of the present invention, the first hub and the second hub are both provided with two symmetrical holes and two protrusions.
[0008] As a further improvement of the present invention, a rubber tire is provided on the wheel hub assembly.
[0009] Beneficial effects of the utility model
[0010] Compared with the prior art, the advantages of the present invention are:
[0011] The utility model can realize automated production and processing by machines by connecting the first hub and the second hub by self-riveting. Compared with traditional processes, it can reduce labor costs and improve production efficiency. The produced hub assembly has a high degree of integration, is quiet when used, and has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0017] See also Figures 1 to 4 A self-riveting silent caster includes a first hub 1 and a second hub 2. The first hub 1 and the second hub 2 are self-riveted to form a hub assembly. Opposing sides of the first hub 1 and the second hub 2 are each provided with a hole 3 and a protrusion 4. The protrusion 4 is located within the hole 3, and a flange 41 is provided on the edge of the protrusion 4 to enable self-riveting connection between the first hub 1 and the second hub 2. The present invention utilizes self-riveting connection between the first hub 1 and the second hub 2 to achieve automated production and processing using a machine. Compared to traditional processes, this method can reduce labor costs and improve production efficiency. The resulting hub assembly has a high degree of integration, is silent during use, and is highly practical.
[0018] Furthermore, it also includes a rotating shaft 5 and a bearing 6. The bearing 6 is set as a single iron core shaft. The bearing 6 is set in the hub assembly, and the bearing 6 is sleeved on the outside of the rotating shaft 5. During the production process, the installation of the rotating shaft 5 and the bearing 6 is set during the self-riveting process of the first hub 1 and the second hub 2, which speeds up the production speed.
[0019] Specifically, the first hub 1 and the second hub 2 are both provided with two symmetrical holes 3 and two protrusions 4, which are adapted to be riveted together.
[0020] Furthermore, a rubber tire 7 is provided on the wheel hub assembly.
[0021] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
