Abstract

The invention discloses an elevator which comprises a lift car. A buffer handle is installed at the top of the lift car and comprises a cylinder, an elastic piece, a piston, a piston rod and a handle body. One end of the cylinder is closed and the other end of the cylinder is opened. The closed end of the cylinder is connected to the top of the lift car, one end of the elastic piece is connected to the closed end of the cylinder, the other end of the elastic piece is arranged on the piston in the cylinder, a closed cavity is formed between the piston and the closed end of the cylinder, a damping hole is formed in the portion, close to the closed end, of the cylinder wall of the cylinder, one end of the piston rod is connected to the piston, and the other end of the piston rod is located on the handle body below the cylinder. According to the elevator, the elastic piece, the cavity and the damping hole are used, so that obtained kinetic energy of the human body falling along with the lift car is absorbed and consumed by the elastic piece and the piston during a reasonable period and at a reasonable movement distance, the problem of passenger death and injury caused when a lift car of an existing elevator accidently falls is solved, and the elevator has the advantages of being simple and practical.

Description

technical field [0001] The present invention relates to an elevator. Background technique [0002] Elevators are a kind of lifting equipment widely used in modern buildings, mainly used to carry people. Under normal circumstances, passenger elevators are safe, but when the car accidentally falls, it often causes casualties to passengers. Contents of the invention [0003] The object of the present invention is to provide an elevator to solve the problem of casualties of passengers caused by the accidental fall of the car in the existing elevator. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] An elevator, comprising a car, a buffer handle is installed on the top of the car, the buffer handle includes a cylinder, an elastic member, a piston, a piston rod and a handle, the cylinder has a closed end and an open end, the The closed end of the cylinder is connected to the top of the car, one end of the elastic me...
