The invention relates to the technical field of brakes for children's bicycles, and discloses an expansion brake for children's bicycles, which comprises a brake box shell, a brake shoe, a driving cam shaft and a rocker arm, the brake shoe is arranged on the inner side of the brake box shell, and the rocker arm is detachably fixed on the outer side of the brake box shell through the driving cam shaft penetrating through the brake box shell. The brake shoe is of a friction integrally-formed symmetrical annular structure, a limiting structure is arranged at one end of the brake shoe and connected to the inner side of the brake box shell in a matched mode, and opening driving clamping ends are arranged at the other end of the brake shoe and abut against the two sides of the cam part of the driving cam shaft in a clamped mode. The problems that in the prior art, a brake for a baby carriage generates harmful components in the continuous braking friction process, bad influences can be generated on the body of the baby and the environment after long-term use, and due to the fact that the brake is mainly made of metal materials, a brake used on the baby carriage is heavy in weight and high in cost are solved.
本发明涉及童车用制动器技术领域,公开了一种儿童自行车用涨闸,包括闸盒外壳、制动蹄、驱动凸轮轴和摇臂,闸盒外壳内侧设有制动蹄,摇臂通过穿装在闸盒外壳上的驱动凸轮轴可拆卸固定在闸盒外壳外侧,所述制动蹄设置为摩擦一体成型对称环形结构,所述制动蹄一端设有限位结构适配连接在闸盒外壳内侧,另一端设有开口驱动夹持端夹持抵接在驱动凸轮轴凸轮部两侧;解决了现有技术中的童车用刹车在不断制动摩擦过程中产生有害成份,长期使用会对儿童身体及环境产生不良影响,以及刹车主要材料为金属材料制成,而导致儿童车上所用制动器的重量重、成本高的问题。
