Problems solved by technology

However, due to design and other reasons, braking mainly depends on the friction with the wheel to increase the resistance of the wheel to complete the braking. It takes a lot of force to complete the braking, and slipping often occurs, especially When carrying heavy items, due to its large inertia, it cannot meet the requirements of timely braking, and may cause personal injury in severe cases

Abstract

The invention discloses a brake caster, which comprises a wheel frame with a central shaft, an insert rod, side wheels on both sides of the wheel frame, an unlocking plate connected to the side wall of the wheel frame by a shaft, and the lower end of which passes backwards through the inner wall of the wheel frame. The unlocking plate is spring-connected, the brake plate is sleeved on the central shaft, and the middle part of the brake plate is downwardly connected to the inner wall of the wheel frame through the brake plate spring; the brake block that can move up and down in the wheel frame above the central shaft, A brake pad that can move forward and backward is provided under the central shaft, and the first brake chainring is fixed on the inner side of the side wheel in a ring shape; the brake block corresponds to the first brake chainring, and the lower end of the insertion rod is ferruled by the second brake chainring. The brake pad corresponds to the second brake chain disc. The invention has the advantages of reasonable structure, convenient use, good safety and reliable locking and unlocking functions.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a brake caster. Background technique [0002] Casters are widely used in dispensing carts, wheelchairs, dining carts and other fields. According to the steering characteristics, it is divided into fixed casters and movable casters. The movable casters can be oriented horizontally at 360 degrees, which is more convenient to use. Some movable casters have a brake mechanism, which can realize orientation and brake functions. However, due to design and other reasons, braking mainly depends on the friction with the wheel to increase the resistance of the wheel rotation to complete the braking. It takes a lot of force to complete the braking, and slipping often occurs, especially When carrying heavy items, due to its large inertia, it cannot meet the requirements of timely braking, and may cause personal injury in severe cases. Contents of the invention [0003] The ...
