Window breaker

Abstract

The invention relates to a window breaker, which comprises a window breaker box, a conical pendulum hammer, an elastic device and a trigger switch, wherein the elastic device can be used for enabling the conical pendulum hammer to rotate; the trigger switch is used for limiting and triggering the rotation of the conical pendulum hammer; the conical pendulum hammer and the elastic device are arranged in the window breaker box; the trigger switch is arranged outside the window breaker box; one end of the conical pendulum hammer is connected with the elastic device; the other end of the conical pendulum hammer is connected with the trigger switch; one side, which is close to a glass window, of the window breaker box is provided with a window breaking hole through which the conical pendulum hammer can pass. The window breaker has the characteristics that the loss is difficult, the reliability is good, the repeated percussion can be carried out, the operation is convenient, and further, the operating time is short.

Description

technical field [0001] The invention relates to a window breaker, in particular to a window breaker used on transportation vehicles. Background technique [0002] In order to break the glass and escape when an accident occurs in the compartment, window breakers are generally installed on the glass in the compartment. The traditional window breaker is generally a hammer or electric or manual trigger, which is placed near the window. When encountering an emergency, the passenger takes off the knocker, breaks the glass and escapes or is controlled by the driver. The window breaker of this kind of structure has the following disadvantages: [0003] 1. Easy to lose. The traditional window breaker is placed in a very conspicuous position of the window, and the hammer is usually stuck in the card slot near the window; if the card is too tight, it is not easy to remove, and if it is loose, it is very easy to lose. [0004] 2. The operation strength required is large. Traditional...

AI Technical Summary

Problems solved by technology

[0003] 1. Easy to lose

The traditional window breaker is placed in a very conspicuous position of the window, and the hammer is generally stuck in the card slot near the window; if the card is too tight, it is not easy to remove, and if it is loose, it is very easy to lose

[0004] 2. The operation strength required is large

Traditional window breakers are made by people tapping or holding a nail hammer to tap the glass, using human power to tap, which requires a large operating force, a large space, and accurate hitting positions.

[0005] 3. Difficult to operate

In the event of a fire, when the compartment is relatively crowded and chaotic, it is not easy to operate by manual tapping

[0006] 4. The operation time is long and complicated

Existing products need to be opened or rotated to adjust the position, and then hit, which requires high quality of operators and operation methods

[0007] 5. The second strike cannot be used repeatedly

Existing electronic control products are all disposable products, and the cost is high
