Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some 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 persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] see figure 1 , the embodiment of the present invention includes:

[0015] A high-load caster, comprising: a fixed plate 1, a fixed seat 2 and a rotating seat 3, the fixed seat 2 is arranged on the lower surface of the fixed plate 1, connected by welding, has a firm structure and is not easy to be damaged.

[0016] The rotating seat 3 is arranged concentrically under the fixed seat 2, and the first bearing 6 is arranged between the rotating seat 3 and the fixed seat 2 for connection. The groove corresponding ...

Abstract

The invention discloses a high-bearing-capacity trundle. The high-bearing-capacity trundle comprises a fixing plate, a fixed seat and a rotating seat. The fixed seat is arranged on the lower surface of the fixing plate. A first bearing is arranged between the rotating seat and the fixed seat and used for connection. A cylinder perpendicularly extending to the upper portion of the fixed seat is arranged in the middle of the rotating seat. An inner stepped hole is formed in the middle of the fixed seat, and the cylinder can penetrate the inner stepped hole. A second bearing which is arranged on the outer portion of the cylinder in a sleeving manner is arranged in the inner stepped hole. Two symmetrical vertical supporting plates are arranged on the lower portion of the rotating seat. A rolling wheel is arranged between the vertical supporting plates. In this way, the high-bearing-capacity trundle achieves steering especially by means of cooperation of the first bearing and the second bearing, so that the rotating flexibility and the torsion strength are improved, and the bearing capacity can be improved. The manufactured high-bearing-capacity trundle is higher in durability and not prone to breakage in use.

Description

technical field [0001] The invention relates to the field of casters, in particular to a high load-bearing caster. Background technique [0002] For the convenience of moving, casters are installed at the bottom of some furniture, home appliances or seats for pushing. Casters are mainly divided into directional wheels and universal wheels. The directional wheels have a strong bearing capacity, but they cannot be turned casually. The steering of the universal wheels is more flexible. [0003] Since the universal wheel can realize steering, it is widely used. Ordinary swivel wheels mostly use a ring of ball structure, which has high friction and limited load-carrying capacity, and the torsion resistance of the rotating structure is poor, and it is easy to break during use. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a high-load-bearing caster, which improves the load-bearing capacity and torsional strength. ...
