Buffer protection device in elevator car

The utility model belongs to the field of elevators, particularly relates to a built-in buffer protection device in an elevator car, and aims to solve the problems that an existing elevator is not provided with a buffer device, the buffer function is difficult to realize and the effect of protecting users is difficult to play when the elevator normally falls and has an accident, the brake of the elevator is relatively single, and the safety of the elevator is influenced. In order to solve the problems that in the prior art, the protection effect is not good enough, according to the scheme, the elevator protection device comprises a rotating speed detector and a traction machine which are arranged on the top of an elevator shaft, and the inner wall of the elevator shaft is slidably connected with an elevator car body and a weight bearing block. The brake function can be achieved through the brake assembly, the wear-resisting plate and the wood plate are arranged, the brake function is achieved in two modes, th
