For manual override on trolley brakes

Abstract

A manual control device for a trolley brake, comprising a housing and a ferrule capable of being inserted into the inner cavity of the housing. The inner cavity of the housing has at least two grooves, and a convex buckle is arranged on the lower part of the outer peripheral surface of the ferrule. There is a cap on the top of the ferrule, and the ferrule is connected with the pull rope that keeps the brake locked. Under the external pressing action of the cap, the upper surface of the convex buckle can be buckled in the concave by automatic rotation. On the bottom surface of the notch at the bottom of the groove, under the action of the external torsion of the cap, the convex buckle can escape from the bottom surface of the notch and rise upwards from the inner cavity of the shell. The return mechanism that can rise upwards under the action of external torsion has the advantage that it can achieve the purpose of accurate braking as long as the cap is pressed by hand. If the cap is not pressed, it means that the cart is not braked. Therefore, the pusher It can clearly know whether the cart has been braked, thereby avoiding accidents caused by not braking the cart.

Description

technical field [0001] The present invention relates to a stroller, in particular to a manual control device for a baby stroller brake. Background technique [0002] There is a Chinese utility model patent with the patent number of 200720060910.4 and the name "Baby Stroller", which discloses a structure, the structure includes a frame, a rail frame mounted on the upper part of the frame, and a rail frame mounted on the upper part of the frame and the rail frame. The push rod between them and the front and rear wheel groups installed at the bottom of the frame are provided with brake mechanisms respectively. between the brake pads and the brake combination mounted on the brake frame. When the stroller turns to the downhill road, the user can step on the brake seat installed on the rear wheel group with his feet, drive the entire brake mechanism to move backwards, and drive the front wheel group on the frame to move backwards. The front and rear wheel groups are moved backwa...

Problems solved by technology

However, this cart brake device needs to be controlled by feet to achieve the purpose of stopping the cart, but the disadvantage of using feet to control is that the cart is easy to break, and because the strength of the feet is large, its force is not easy to grasp, and it is easy to step on it. Bad stepping blocks, and it is inconvenient to use with feet. In addition, when using feet to control, the stroller is not braked, and it is not realized; when the baby stroller is on a slope, and In the case that the adult does not pay attention and does not protect the stroller, that is, the stroller will automatically slide down the slope without the action of external force, resulting in accidents. Injury, the severe one also can endanger the safety of baby's life, moreover, requires caregiver to distract attention from child and surrounding environment with foot brake, makes operation not only troublesome but also inconvenient
