Problems solved by technology
[0002] Most of the existing universal wheels with brakes use brake pads or star-shaped lock teeth to cooperate with lock projections and locking methods, but these locking structures do not have self-locking insurance functions, and can only be locked in one direction. In the reverse direction, it is easy to loosen, which makes the locking effect not good, while other brake universal wheels with safety function are realized by adding safety function mechanism. This structure is more complicated, and after safety locking, it needs to be manually Turn on the insurance to unlock the lock, the operation is troublesome

The invention provides a universal wheel with a brake function. The universal wheel with the brake function has a simple structure and a self-locking insurance function, and can be convenient to relieve the insurance function. The universal wheel with the brake function comprises a support, a bracket and an roll wheel; the support is connected with the roll wheel by the bracket; star-shaped locking teeth are arranged on the center axle of the roll wheel; a braking pedal is hinged on the bracket; locking lugs are arranged on the braking pedal; the locking lugs can be matched with the star-shaped locking teeth of the roll wheel; a locating lug is arranged on the braking pedal; a limiting lug is arranged on the bracket; the locating lug and the limiting lug correspond and can perform back-front double-way clamping and matching; and at least one of the two matching surfaces is an inclined transition plane when the back-front double-way clamping and matching is performed.
Description
technical field [0001] The invention relates to a universal wheel with brakes, in particular to a universal wheel with brakes capable of self-locking safety. Background technique [0002] Most of the existing universal wheels with brakes use brake pads or star-shaped lock teeth to cooperate with lock projections and locking methods, but these locking structures do not have self-locking insurance functions, and can only be locked in one direction. In the reverse direction, it is easy to loosen, which makes the locking effect not good. Other brake universal wheels with safety function rely on additional safety function mechanisms to achieve this structure. This structure is more complicated, and after the safety lock needs manual Turn on the insurance to unlock the lock, which is troublesome to operate. Contents of the invention [0003] The object of the present invention is to provide a universal wheel with a brake, which is simple in structure, capable of self-locking s...
