DETAILED DESCRIPTION

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 and 2 As shown, this embodiment provides a combined caster, which is mainly composed of a caster body 1, a foot cup body 2, a mounting plate 3 and a locking assembly (countsunk screw 4, gasket 5, spring washer 6, first nut 7, second nut 8) and the like.

[0026] like Figure 3 As shown, the caster body 1 comprises a connecting plate 101, a roller connector 102, and a roller 103, arranged sequentially from top to bottom. The bottom surface of the connecting plate 101 and the top surface of the roller connector 102 are welded together via a welded convex surface 104. This welded convex surface 104 increases the welding space. The roller connector 102 and the roller 103 are rotatably coupled together using a long-stem bolt as an axis, which is then secured in place by a nut.

[0027] like Figure 4 As shown, the foot cup body 2 includes, from top to bottom, a support screw 201, a base plate 202, and a base plate pad 203. The support screw 201 is mounted at the center of the base plate 202 (the two are threadedly connected), and the outer diameter of the base plate 202 is twice that of the support screw 201. The base plate pad 203 is a rubber pad that acts as a buffer.

[0028] like Figure 5 As shown, the mounting plate 3 is provided with a set of first connection holes 301 and a set of second connection holes 302. The mounting plate 3 includes a mounting truncated cone portion 304 integrally provided on the bottom side. The mounting truncated cone portion 304 is provided with a third connection hole 303. Figure 6As shown, the mounting plate 3 is configured as a symmetrical structure, the center line connecting the caster body 1 and the foot cup body 2 coincides with the symmetry axis o of the mounting plate 3, a group of first connecting holes 301 are symmetrically arranged relative to the symmetry axis of the mounting plate 3, and a group of second connecting holes 302 are symmetrically arranged relative to the symmetry axis of the mounting plate 3.

[0029] like Figure 1 and 2 As shown, assemble the caster body 1, the foot cup body 2, and the mounting plate 3:

[0030] A flat plate placement groove 305 is provided on the bottom surface of the mounting plate 3, the connecting plate 101 is in the flat plate placement groove 305 and the connecting plate 101 is adapted to the flat plate placement groove 305, and the countersunk screw 4 passes through the first connecting hole 301, the connecting plate 101, the gasket 5 and the spring washer 6 and is threadedly connected to the first nut 7.

[0031] The support screw 201 is threadedly connected to the third connection hole 303. Two second nuts 8 are installed between the base 202 and the mounting truncated cone 304. The upper second nut 8 abuts the bottom of the mounting truncated cone 304 to lock the relative position between the mounting truncated cone 304 and the support screw 201. The lower second nut 8 abuts the top of the base 202 to lock the relative position between the base 202 and the support screw 201.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
