Dual-pedal-control caster wheel

Abstract

The invention relates to a dual-pedal-control caster wheel. The dual-pedal-control caster wheel comprises a caster wheel main frame, wherein wheel sheets and side covers are arranged at the two sides of the caster wheel main frame, the wheel sheets are provided with brake gear rings, a brake slide block is arranged in an internal cavity of the caster wheel main frame, a first offsetting spring is arranged between the upper side part of the brake slide block and the internal cavity of the caster wheel main frame, a sectorial brake rack is arranged at a side part of the brake slide block, the brake slide block is a hollow slide block, of which the middle part is provided with a long slotted hole, a brake pedal is sleeved on a transverse rod of the internal cavity of the caster wheel main frame, and a cam part is arranged on the brake pedal; and a brake-off pedal which is used for brake-off is further arranged on the caster wheel main frame in a penetrating manner, a driving end of the brake-off pedal can extend into a slotted hole of the upper side part of the brake slide block and be matched with the brake pedal, and a second offsetting spring is arranged between the brake-off pedal and an upper through hole of the caster wheel main frame. According to the dual-pedal-control caster wheel, the brake pedal and the brake-off pedal are arranged at the same side part, so that the stress directions are the same during braking and braking-off operation, and the use is flexible and convenient.

Description

technical field [0001] The invention relates to a dual-pedal control caster. Background technique [0002] When people invented the wheel, it became relatively simple to move large objects, but the defects of early wheels were particularly obvious, that is, they could only walk in a straight line or could not brake, which limited the flexibility of moving objects and the safety of stopping Later, people invented wheels with full freedom and braking structure, which is what we call casters or universal wheels now. With the continuous development of science and technology, more and more equipment needs to be used for office and operation on the move. Taking into account the versatility, safety and high utilization of the equipment, casters must become an indispensable part. Although the emergence of casters has brought about an efficiency revolution in the era of modernization for people's handling, especially moving objects, with customers' in-depth understanding of the perf...
