Ejection type fixed window breaker

Abstract

The invention discloses an ejection type fixed window breaker and aims to provide a high-efficiency and safe window breaker to solve the technical problem. The ejection type fixed window breaker comprises a base, a fixing screw, a supporting rear seat, a torsion spring, a rotating arm, a safety pin, a pull ring and a rivet. The base is fixed at a corner of an edge on the outer side of window glass through the fixing screw; the rear end of the base is connected with the supporting rear seat; the front end of the base is connected with the torsion spring; the upper end of the torsion spring is connected with the rotating arm; two ends of the torsion spring are respectively fixed on the base and the rotating arm; the safety pin penetrates through a through hole in the supporting rear seat and a through hole in the rotating arm; the pull ring is arranged on the rotating arm, and the rivet is mounted below the rotating arm; the rivet is aligned with the corner of the window glass. The ejection type fixed window breaker has the advantages that potential energy of a spring is instantaneously released in the device, and the glass is impacted by the rivet, so that the glass is broken, and a user does not need to wave the arm with big force during use. The device is fixed at the corner of the car window and is difficulty lost, the impact point is positioned at the corner of the glass, the glass is easily broken, and the window breaker is simple in operation process, safe and reliable.

Description

technical field [0001] The invention relates to an emergency escape tool, in particular to a window breaker. Background technique [0002] Urban public transport vehicles such as buses, buses, trains, etc. are basically air-conditioned vehicles, and the windows generally cannot be opened. In order to facilitate passengers to escape in case of emergency, the vehicles are basically equipped with safety hammers. When using a safety hammer, ordinary passengers do not know that the stress on the corners of the window is unbalanced and it is easy to break, so they subconsciously hammer the center of the window. When an accident happened at the same time, when the passengers in the bus were crowded and flustered, many passengers picked up the safety hammer and did not have enough space to stretch their arms and could not use enough force to smash the window, or when the car fell into the water. , the passengers in the car cannot swing their arms in the water, making the windows no...

Problems solved by technology

When using a safety hammer, ordinary passengers do not know that the stress on the corners of the window is unbalanced and it is easy to break, so they subconsciously hammer the center of the window

When an accident happened at the same time, when the passengers in the bus were crowded and flustered, many passengers picked up the safety hammer and did not have enough space to stretch their arms and could not use enough force to smash the window, or when the car fell into the water. , the passengers in the car cannot swing their arms in the water, making the windows not easy to break

In addition, the safety hammer is easily lost in the compartment, and passengers cannot break the window when danger occurs, causing people in distress to lose the chance of escape
