The invention discloses a damping pressure lock which is characterized in that a connecting spring is arranged between a connecting pipe and a base, a brake rod is sleeved with the base, the connecting pipe can descend along with the brake rod when being stressed, and at the moment, a brake pad on the brake rod can make contact with a wheel to achieve braking; a handle part on the device is connected with a brake cable, the brake cable drives a brake rod to ascend and descend after the handle is pulled, and the functions of manual braking and brake releasing are achieved. Meanwhile, the connecting spring between the connecting pipe and the base enables the device to have a cushioning function; the device achieves the functions of self-locking, cushioning and manual braking at the same time.
本专利公开了一种减震压力锁,其特征在于,连接管和底座之间有连接弹簧,刹车杆套在底座里面,连接管受到压力时会连同刹车杆下降,此时刹车杆上的刹车片会接触轮子实现制动;装置上手柄部分连接着刹车线,拉动手柄后刹车线带动刹车杆上升下降,实现手动刹车和解除刹车的功能;同时,连接管和底座间的连接弹簧使装置具有缓震的功能;装置同时实现了自锁,缓震和手动刹车的功能。
