Problems solved by technology

[0005] However, the above-mentioned casters will inevitably be worn or deformed during use. If the degree of wear of the rollers causes its size to change beyond the maximum distance that the end of the brake spring can be pressed down, the brake spring will no longer be able to adjust The roller acts as a brake, which reduces the practicality of the caster and the service life is not long

Abstract

The invention provides a braking trundle, belongs to the technical field of machinery, and solves the problem of low practical applicability and short service life of existing braking trundles. The braking trundle comprises a foot stool capable of being mounted at the bottom of a device and wheels connected with the foot stool, two sides of the foot stool are connected with a supporting plate, the outer end of the supporting plate is hinged with the wheels, a rotating shaft position of the wheels is provided with a protruding block, the inner side of the supporting plate is provided with a cam, and the outer side of the supporting plate is connected with a pedal. The cam extends from the inner side of the supporting plate and is connected with the pedal, the inner side of the supporting plate is fixedly connected with cranks respectively arranged on two sides of the cam, the inner ends of the crank respectively abut against the inner sides of the cam, the outer ends of the two cranks are respectively arranged on two sides of the protruding block, and when the cam rotates, outer ends of the two cranks can contract and clamp two sides of the protruding block. The braking trundle has the advantages of being convenient to brake, stable in use, wide in applicability and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a brake caster, in particular to a double brake caster. Background technique [0002] Caster is a common product, which refers to the wheel that is connected to the lower part of the transportation device and can change direction freely. It can be roughly divided into fixed caster and swivel caster. It is usually installed on the bottom of appliances such as furniture, carts or lathes, so that the appliance can be moved flexibly and conveniently. Since the appliance needs to be stationary after it has been moved, it is necessary to provide a braking device on the casters. [0003] The brake pads of traditional brake casters are punched and formed by spring steel sheets, and a fixed distance is maintained between the brake pads and the wheels. By shaking the brake plate, the brake pads are pressed against the wheel tread to achieve the braking effect. [0004] For example, a Chi...
