Safety hammer equipped in a rail transit train

Abstract

The invention relates to the technical field of safety hammers, and specifically discloses a safety hammer equipped in rail transit trains; it includes a hammer head seat, a first connecting rod, a second connecting rod and a handle. A cylindrical hammer head is arranged in the cavity, a round hole is opened on the front side of the hammer head seat, the front end of the cylindrical hammer head protrudes from the round hole, and a hammer tip is arranged on the front end of the cylindrical hammer head protruding from the round hole. The rear side of a connecting rod is provided with a bar-shaped groove, the middle section of the bar-shaped groove is fixedly provided with a pin rod, the first pin rod is covered with a first torsion spring, and the two ends of the first torsion spring extend downward with A steel bar is connected with a rotating arm on the first pin rod, the inner surface of the rotating arm is connected with the steel bar, and a knocking block is fixed on the outer surface of the lower end of the rotating arm; the safety hammer disclosed in the present invention only needs to strike the tempered glass The disintegration and fragmentation of the entire tempered glass can be realized at one time, and it has the function of active safety protection. Its structural design is novel and practical.

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
