Safety hammer arranged in rail transit train

Abstract

The invention relates to the technical field of safety hammers, and specifically discloses a safety hammer arranged in a rail transit train. The safety hammer comprises a hammer base, a first connecting rod, a second connecting rod and a handle, wherein a cavity is formed in the hammer base, a cylindrical hammer head is arranged in the cavity, a round hole is formed in the front side surface of the hammer base, the front end of the cylindrical hammer head extends out of the round hole, and a hammer head tip is arranged at the front end, extending out of the round hole, of the cylindrical hammer head; a strip-shaped groove is formed in the rear side surface of the first connecting rod, a pin rod is fixedly arranged in the middle section of the strip-shaped groove and sleeved with a first torsional spring, the two ends of the first torsional spring extend downwards to form steel bars, a rotary arm is rotationally connected to the first pin rod, the inner side surface of the rotary arm isconnected to a steel bar, and a knocking block is fixed to the outer side surface of the lower end of the rotary arm. According to the safety hammer disclosed by the invention, the whole tempered glass can be disintegrated and broken only by knocking the tempered glass once, so that active safety protection effect is achieved, the structural design is novel, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of safety hammers, and specifically discloses a safety hammer equipped in rail transit trains. Background technique [0002] The safety hammer is an auxiliary escape tool installed in a closed cabin, and it is generally installed in a place that is easy to get in a closed cabin such as a car. In the event of a fire or falling into water in a closed cabin such as a car, it can be conveniently taken out and smashed into glass windows and doors for smooth escape. [0003] At present, public rail transit trains such as trains, high-speed rails, subways, etc. will be equipped with a safety hammer near the window to smash the window glass to escape in an emergency. The glass is made of tempered glass, and when the tempered glass is struck, the surface of the whole piece of glass will be broken into glass particles, but the broken glass particles will still be connected together, and a second strike is required to...

Problems solved by technology

Yet when the user knocks the toughened glass of the car window, it needs multiple knocks to break the glass, which reduces the time for passengers to smash the glass to save themselves; in addition, when the toughened glass is broken, the human body is exposed. In front of tempered glass, it is easy to cause harm to the human body

Therefore, aiming at the above-mentioned deficiencies of the existing safety hammers equipped in rail transit trains, it is an unresolved problem to design a safety hammer that can break the toughened glass and can protect the user by knocking. technical issues
