Description

Technical Field

[0001] The utility model relates to the technical field of load-bearing casters, in particular to a wear-resistant reinforced load-bearing caster. Background Art

[0002] Casters are a general term, including movable casters, fixed casters and movable casters with brakes. Movable casters are what we call universal wheels, and their structure allows 360-degree rotation; fixed casters are also called fixed casters, which have no rotating structure and cannot turn. Usually, the two types of casters are generally used in combination. For example, the structure of a trolley is two fixed wheels in the front and two universal wheels in the back near the push handle. Casters are made of various materials, such as PP casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, iron core nylon casters, iron core PU casters, etc.

[0003] After searching, a Chinese utility model patent disclosed a wear-resistant reinforced caster with announcement number CN218171908U, comprising a caster fixing bracket and a caster body, a caster mounting cavity being provided on the inner side of the caster fixing bracket, and support reinforcement plates being provided on the upper ends of the left and right sides of the caster fixing bracket. The high temperature generated by the friction between the caster body and the bottom surface can pass through a plurality of groups of circular ring grooves arranged on the surface of the device, so that the high-temperature gas can flow through the circular ring grooves more smoothly to discharge heat as the caster body rotates, thereby solving the problem that the friction loss of the caster body due to the inability to discharge the high temperature smoothly seriously reduces the service life, thereby improving the wear resistance of the caster, and through the design combination of the circular ring reinforcement groove, the steel block and the supporting steel column and the reinforcing arc rod with the caster body, when the caster body moves heavy objects, the caster body can improve the overall supporting strength of the caster body for the heavy object and the stability after reinforcement through the combination of the equidistantly arranged steel rings and the supporting steel columns.

[0004] However, the device often lacks the function of allowing the roller to run independently and increase the load-bearing effect. When in use, the load-bearing casters need to be pushed and pulled by manpower, resulting in a situation where the operation of the device consumes a lot of manpower. Not only that, the device also lacks the function of locking the casters. When in use, the casters cannot stop steadily when they reach the specified position, causing the casters to easily deviate. Summary of the invention

[0005] The purpose of the utility model is to provide a wear-resistant reinforced load-bearing caster to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wear-resistant reinforced load-bearing caster, comprising a mounting plate, a first connecting plate fixedly connected to the bottom of the mounting plate, a rotating shaft rotatably connected to the inner surface of the first connecting plate, a bidirectional motor rotatably connected to one end of the rotating shaft, a roller body fixedly connected to the outer surface of the rotating shaft, a load-bearing layer fixedly connected to the outer surface of the roller body, and a wear-resistant layer fixedly connected to the outer surface of the load-bearing layer;

[0008] The outer surface of the first connecting plate is fixedly connected to the second connecting plate, one end of the second connecting plate is rotatably connected to a support rod, the outer surface of the support rod is fixedly connected to a mounting column, one end of the mounting column is fixedly connected to a pedal, the bottom of the pedal is fixedly connected to a limiting plate, and a blocking block is provided at the bottom of the limiting plate.

[0009] Preferably, a mounting bolt is fixedly connected to the top of the mounting plate, and screws are fixedly connected to the four corners of the top of the mounting plate.

[0010] Preferably, the outer surface of the rotating shaft is fixedly connected with a roller body. A slot is provided in the middle of the roller body.

[0011] Preferably, a pedal is fixedly connected to one end of the mounting column, and an anti-slip layer is fixedly connected to the top of the pedal.

[0012] Preferably, both ends of the bidirectional motor are rotatably connected to a rotating shaft, and the outer surface of one end of the rotating shaft is fixedly connected to a roller body.

[0013] Preferably, one end of the second connecting plate is rotatably connected to a support rod, and the other end of the second connecting plate is fixedly connected to a fixing buckle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The wear-resistant reinforced load-bearing caster is provided with a rotating shaft, a roller body, a load-bearing layer, a wear-resistant layer and a bidirectional motor. When in use, the bidirectional motor drives the rotating shafts on both sides to rotate, and the rotation of the rotating shaft drives the roller body to rotate. Then, through the coordinated use of the load-bearing layer and the wear-resistant layer, the roller can move by itself under the drive of the motor to reduce manpower and the two casters can enhance the load-bearing effect.

[0016] The wear-resistant reinforced load-bearing caster is provided with a pedal, a limit plate, a clamping block and a clamping slot. When in use, the pedal is pressed to rotate the mounting column on the support rod, and the clamping block at the bottom of the limit plate is clamped in the clamping slot in the middle of the roller body, thereby achieving the effect of limiting the device and preventing the device from deviating after reaching the specified position.
