Abstract
Description
Technical Field
[0001] This utility model belongs to the field of caster technology, specifically relating to an anti-deformation caster. Background Technology
[0002] Casters are widely used in various mobile devices and facilities in industries such as industrial manufacturing, logistics, medical equipment, and furniture, serving as a convenient means of movement and positioning. However, traditional casters often deform under heavy loads or during prolonged use due to material fatigue or improper structural design, leading to a decrease in their rotational performance and affecting the overall stability and lifespan of the equipment. Utility Model Content
[0003] The main purpose of this utility model is to provide an anti-deformation caster that can effectively resist deformation and improve the stability and service life of the caster.
[0004] To achieve the above objectives, this utility model provides an anti-deformation caster, which includes a caster tire, a caster connecting housing, and a mounting plate. The caster tire is disposed inside the caster connecting housing, and a connector is provided on the top of the caster connecting housing. The mounting plate is rotatably connected to the caster connecting housing through the connector. The top surface of the caster connecting housing is a horizontal plane, and the mounting plate is horizontally mounted on the top surface of the caster connecting housing. The area of the mounting plate is larger than the area of the top surface of the caster connecting housing.
[0005] The anti-deformation caster provided by this utility model, compared with the traditional caster installation, is installed by a mounting plate. The mounting plate has a large area and good pressure bearing capacity, thus effectively resisting deformation and improving the stability and service life of the caster.
[0006] In one possible implementation, the connector includes a connecting rod with a circular limiting plate on it. The diameter of the limiting plate is larger than the diameter of the connecting rod. A mounting hole, also larger than the diameter of the limiting plate, is provided on the mounting hole. An inner limiting edge, smaller in diameter than the diameter of the limiting plate, is provided within the mounting hole. The connector, comprising the connecting rod and the circular limiting plate (with a larger diameter than the connecting rod), engages with the mounting hole and the inner limiting edge on the mounting plate to form a stable rotational connection, allowing the caster to rotate freely.
[0007] In one possible implementation, a slotted mounting hole is provided at each of the four corners of the mounting plate. These slotted mounting holes at the four corners provide flexible installation, allowing the casters to adapt to different installation needs and increasing their versatility.
[0008] In one possible implementation, the caster connecting housing includes two connecting plates, on which a mounting shaft is bolted. The caster tire is rotatably connected to the mounting shaft. The caster connecting housing, composed of two connecting plates and bolted to the mounting shaft, provides stable support and rotational performance.
[0009] In one possible implementation, the connecting plate is inclined. The inclined arrangement of the connecting plate increases the stability of the caster, allowing the force to be effectively dispersed when subjected to uneven forces, reducing localized stress on the caster tire or connecting housing, thereby improving the caster's resistance to deformation.

[0012] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0013] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0014] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0015] See attached diagram. Figure 1 and Figure 2As shown in the figure, the present invention provides an anti-deformation caster including a caster tire 1, a caster connecting housing 2, and a mounting plate 3. The caster tire 1 is disposed inside the caster connecting housing 2. A connector 4 is provided on the top of the caster connecting housing 2. The mounting plate 3 is rotatably connected to the caster connecting housing 2 through the connector 4. The top surface of the caster connecting housing 2 is a horizontal plane. The mounting plate 3 is horizontally mounted on the top surface of the caster connecting housing 2. The area of the mounting plate 3 is larger than the area of the top surface of the caster connecting housing 2.
[0016] The anti-deformation caster provided by this utility model, compared with the traditional caster installation, is installed by mounting plate 3. The mounting plate 3 has a large area and good pressure bearing capacity, so it can effectively resist deformation and improve the stability and service life of the caster.
[0017] In one possible implementation, the connector 4 includes a connecting rod 41 with a circular limiting plate 42 on it. The diameter of the limiting plate 42 is larger than the diameter of the connecting rod 41. The mounting plate 3 has a mounting hole 5, the diameter of which is larger than the diameter of the limiting plate 42. A limiting inner edge 6 is provided within the mounting hole 5, the inner diameter of which is smaller than the diameter of the limiting plate 42. The connector 4, including the connecting rod 41 and the circular limiting plate 42 (whose diameter is larger than the connecting rod 41), engages with the mounting hole 5 and the limiting inner edge 6 on the mounting plate 3 to form a stable rotational connection, allowing the caster to rotate freely.
[0018] In one possible implementation, a waist-shaped mounting hole 7 is provided at each of the four corners of the mounting plate 3. The waist-shaped mounting holes 7 at the four corners of the mounting plate 3 provide flexible installation, allowing the caster to adapt to different installation requirements and increasing the applicability of the caster.
[0019] In one possible implementation, the caster connecting housing 2 includes two connecting plates 8, on which a mounting shaft is fixed by bolts. The caster tire 1 is rotatably connected to the mounting shaft. The caster connecting housing 2, composed of two connecting plates 8 and a mounting shaft fixed by bolts, provides stable support and rotational performance.
[0020] In one possible implementation, the connecting plate 8 is inclined. The inclined arrangement of the connecting plate 8 increases the stability of the caster, so that when subjected to uneven forces, the force can be effectively dispersed through the inclined connecting plate 8, reducing the local stress on the caster tire 1 or the connecting housing, thereby improving the caster's resistance to deformation.
[0021] It is worth mentioning that those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
