Description

Technical Field

[0001] The present application relates to the technical field of casters, and in particular to a heavy-duty caster with an anti-loosening brake. Background Art

[0002] With the continuous development of society, people have higher and higher requirements on the structure and function of wheels. When the existing brake casters carry heavy goods, due to the double-wheel design, when the center gap of the double wheels encounters stones during rotation, when the stones are stuck in the center gap between the two rollers, the rollers cannot operate normally. When the front wheel suddenly locks, the vehicle body continues to move forward due to inertia, and the mass of the vehicle body and the transported objects is heavy, the entire device will burst forward, posing certain safety hazards. Therefore, we propose an anti-loosening brake heavy-duty caster to solve this problem.

When the sole of the foot is away from the top of the pedal 7, due to the elastic characteristics of the two springs 11, the spring 11 pushes the connecting plate 9 to extend downward, thereby resetting the pedal 7, a foot brake pad 8 is installed at the bottom of the pedal 7, an anti-slip rubber pad is arranged on the outer side of the foot brake pad 8, and a rotating component is arranged on the inner side of the supporting frame 5.

[0022] Reference Figure 1-4 Two circular holes 12 are symmetrically provided on the outer side of the support frame 5, and the same plug rod is inserted through the inner side of the two circular holes 12. The rotating assembly includes a roller 6, which is installed on the outer side of the plug rod. The roller 6 is made of high-strength alloy steel material. The two sides of the plug rod are connected and limited by nuts. A plurality of transverse slide grooves are provided on the outer side of the pedal 7. The slide grooves are provided to prevent slipping. The outer side of the roller 6 matches the bottom of the foot brake pad 8; the support frame 5 body: is made of wear-resistant and high-strength materials, such as polyurethane and metal, to meet the durability requirements of long-term operation; by stepping on the top of the pedal 7 with the toes, the pedal 7 is rotatably connected to the support frame 5 On the inner side, a foot brake piece 8 is installed at the bottom of the pedal 7, and the other side of the pedal 7 drives the connecting plate 9 to move upward, and the foot brake piece 8 moves downward to rub the outer side of the roller 6, completing the limitation of the roller 6.

[0023] The implementation principle of the anti-loosening brake heavy-duty caster of the embodiment of the present application is as follows: when the staff is using this device and needs to brake the device, the staff only needs to step on the top of the pedal 7 with the tiptoe. Since the pedal 7 is rotatably connected to the inner side of the support frame 5, a foot brake pad 8 is installed at the bottom of the pedal 7. The other side of the pedal 7 drives the connecting plate 9 to move upward, and the foot brake pad 8 moves downward to rub the outer side of the roller 6 to complete the position limitation of the roller 6. The friction between the anti-slip pad and the steel effectively prevents the occurrence of sliding or loosening, improves the reliability of the brake, and the single-wheel design well prevents stones from being stuck between the two wheels, avoiding the safety hazard caused by stones when the device moves faster, and the high-strength alloy steel material has a high hardness, which further ensures the safety of the device transportation, and changes the friction by changing the force, which is suitable for a variety of application scenarios;

[0024] When the sole of the foot is away from the top of the pedal 7, due to the elastic characteristics of the two springs 11, the springs 11 push the connecting plate 9 to extend downward, thereby resetting the pedal 7, preventing the foot brake pad 8 from rubbing against the outside of the roller 6 during the movement of the device, thereby improving the efficiency of transportation.
