Description

Technical Field

[0001] This utility model relates to transportation equipment in the industrial field, specifically to casters for transportation equipment. Background Technology

[0002] Industrial casters are a type of swivel caster. They have a wide range of applications and can be installed on the bottom of containers, boxes, and trailer racks to facilitate the movement of heavy objects. However, because industrial casters bear heavy loads and have high inertia, slowing down and stopping them can be difficult. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a braking device for industrial casters.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a silent industrial caster equipped with a braking device, including a fixed connecting seat, a roller bracket pivotally connected to the fixed connecting seat, and a roller pivotally connected to the roller bracket. A braking device is installed on the roller bracket, the braking device including a brake plate and a brake spring. The brake plate is hinged to the roller bracket, the roller bracket is provided with a spring winding shaft, the brake spring passes around the spring winding shaft, and the tail end of the brake spring abuts against the inner side of the brake plate so that the front end of the brake plate abuts against the roller bracket, and the front end of the brake spring abuts against the inner top wall of the roller bracket.

[0005] When the operator presses the brake pedal, the tail end of the brake spring bends and comes into frictional contact with the roller, braking the roller. When the operator releases the brake pedal, the brake spring releases its elastic potential energy, the brake pedal rotates upward to return to its original position, and the front end of the brake pedal abuts against the roller bracket.

[0006] The inner top wall of the roller bracket is provided with a limiting groove, and a limiting block is provided in the limiting groove. The brake spring has an upwardly protruding tongue in the middle, which fits in the limiting groove and abuts against the limiting block. With this design, the brake spring can be stably positioned on the roller bracket.

[0007] The brake spring has an arc-shaped recessed structure that mates with the spring winding shaft. This design not only helps the brake spring stay stable on the spring winding shaft, but also allows the tail end of the brake spring to bend and deform while the front end remains stationary.

[0008] The brake spring has a nipple structure on the part that abuts against the brake plate, and the nipple structure faces the roller. The contact between the nipple structure and the roller helps to improve the braking effect.

[0009] The roller includes an axle mounted on a roller bracket, a bearing mounted on the axle, a hub mounted on the bearing, and a rubber coating surrounding the hub. The hub has several axial through holes distributed along its circumference and radial direction. The axial through holes and the rubber coating serve to reduce noise, resulting in a quiet roller.

[0010] A guard plate is provided between the wheel hub and the roller bracket to prevent the roller from shifting on the axle, and to prevent the side of the roller from contacting the roller bracket.

[0011] Technical effects of this utility model:

[0012] First, this utility model utilizes the friction between the brake spring and the roller for braking, and the brake spring facilitates the reset of the brake plate after braking.

[0013] Secondly, the axial through holes and rubber coating on the roller of this utility model are conducive to the noise reduction of the roller, so that the roller has a silent effect. Attached Figure Description

[0026] Combination Figures 1 to 3A silent industrial caster equipped with a braking device includes a fixed connecting seat 10, a roller bracket 20 pivotally connected to the fixed connecting seat, and a roller 30 pivotally connected to the roller bracket. A braking device is installed on the roller bracket, and the braking device includes a brake plate 40 and a brake spring 50. The brake plate is hinged to the roller bracket, and the roller bracket is provided with a spring winding shaft 21. The brake spring passes around the spring winding shaft, and the tail end of the brake spring abuts against the inner side of the brake plate so that the front end of the brake plate abuts against the roller bracket, and the front end of the brake spring abuts against the inner top wall of the roller bracket.

[0027] like Figure 4 The inner top wall of the roller bracket 20 is provided with a limiting groove 22, and a limiting block 23 is provided in the limiting groove. The brake spring 50 is provided with an upward protruding tongue 51 in the middle. The tongue fits in the limiting groove and abuts against the limiting block.

[0028] like Figure 5 The brake spring 50 is provided with an arc-shaped recessed structure 52, which cooperates with the spring winding shaft 21.

[0029] like Figure 3 The brake spring 50 is provided with a nipple structure 53 on the part that abuts against the brake plate 40, and the nipple structure faces the roller 30.
