Problems solved by technology

[0003] Most of the existing emergency valves are knob-type, but the height of most of the knob handles is generally low, and the knob handle is made of ABS hard plastic material. Although there are anti-slip ribs on the handle, it is still difficult to grasp, and the rotation damping is large. prone to difficulties in use

Abstract

The invention discloses an emergency valve and a passenger car, and relates to the technical field of emergency start and stop equipment. The emergency valve comprises a pressing assembly, a base and a valve body. The base is used for being connected with a car body. The pressing assembly comprises a pressing piece which is in sliding connection with the base, a limiting piece arranged on the base, a position clamping piece rotationally connected to the pressing piece, and a position clamping elastic piece arranged between the pressing piece and the position clamping piece. The side face, away from the pressing piece, of the position clamping piece is provided with a first position clamping part in a protruding manner. The position clamping elastic piece is arranged between the pressing piece and the position clamping piece so that the first position clamping part can abut against the side face of the limiting piece, and the first position clamping part tends to rotate towards the limiting piece. When the pressing piece moves in the first direction, the communication state of the valve body can be driven and switched, the first position clamping part is driven to move along the side face of the limiting piece, the first position clamping part abuts against the end face of the first limiting end, and accordingly the communication state is kept. The emergency valve and the passenger car have the characteristic that operation is convenient.

Description

technical field [0001] The invention relates to the technical field of emergency opening and closing equipment, in particular to an emergency valve and a passenger car. Background technique [0002] As the key equipment of public transportation equipment such as passenger cars and trains, emergency valves can be operated by passengers to open the doors urgently in case of emergency situations such as vehicle failures. [0003] Most of the existing emergency valves are knob-type, but the height of most of the knob handles is generally low, and the knob handle is made of ABS hard plastic material. Although there are anti-slip ribs on the handle, it is still difficult to grasp, and the rotation damping is large. Difficulty in use is prone to occur. [0004] In view of this, it is particularly important to develop and design a kind of emergency valve and passenger car that can solve the above-mentioned technical problems. Contents of the invention [0005] The purpose of the...
