Problems solved by technology
Hit the glass with an escape hammer to break the glass. Swinging the escape hammer requires a large space to realize. When a dangerous situation occurs, the crowd in the car is tense and crowded, and it often takes time to make room for swinging the escape hammer.
In order to smash a window, due to the inaccurate grasp of the force and the inaccurate angle of the hammer, it often takes several consecutive knocks, and sometimes the best escape time will be missed

Embodiment Construction
[0018] Such as Figure 1 to Figure 6 As shown, a window breaker with double springs is mainly composed of a base 1, a pressure plate 2, a connecting shaft 3, a striker 4 and two springs 5.
[0019] An upwardly protruding symmetrical base ear 11 is respectively provided at both ends of the side of the base. Correspondingly, the two ends of the side of the pressure plate 2 are also provided with corresponding upwardly protruding pressure plate ears 21. An intermediate lug 22 with the same structure as the lug of the pressure plate is provided between them; the pressure plate is placed on the base so that each lug of the pressure plate is adjacent to the corresponding lug of the base, and the connecting shaft passes through the lugs on the lug of the base in turn. Shaft hole, the shaft hole on the pressing plate lug, a spring 5, the middle lug 22, another spring, the shaft hole on the other pressing plate lug and the shaft hole on the other base lug, so that the pressing plate an...

A window breaking device with double springs mainly comprises a base, a pressure plate, a connecting shaft, a striker and two springs. Upward projecting symmetrical base connecting lugs are arranged at two ends of the side of the base, correspondingly, corresponding upward projecting pressure plate connecting lugs are arranged at two ends of the side of the pressure plate, a middle connecting lugis arranged between the two pressure plate connecting lugs, the structure of the middle lug is as same as that of each pressure plate connecting lug, the pressure plate is pulled by a handle, the twosprings are compressed, strength of spring reset drives the striker to rapidly impact glass after the handle is released, the contact surface of the striker and the glass is provided with a point, pressure intensity is higher when the contact surface is smaller under the same strength, the glass is easily broken by the high pressure intensity, the window breaking device is taken down from the glass after the glass is broken, the broken glass is pushed outwards to form a window hole, escaping can be achieved, the window breaking device is simple to operate and small in occupied space, the glasscan be rapidly broken by small strength, and influence on surrounding environments is less.
Description
technical field [0001] The invention relates to a window breaker with double springs capable of breaking window glass. Background technique [0002] The glass windows on the bus are fixed in an airtight manner, and the glass is usually toughened glass. When a dangerous situation occurs in the car and the glass window needs to be opened to escape, the escape hammer equipped in the car is used to knock the window glass, so that the glass is broken to form a window hole to escape from the window hole. Hit the glass with an escape hammer to break the glass, and swinging the escape hammer requires a large space. When a dangerous situation occurs, the crowd in the car is tense and crowded, and it often takes time to make room for swinging the escape hammer. In order to smash a window, due to the inaccurate grasp of the force and the inaccurate angle of the hammer, it often takes several consecutive knocks, and sometimes the best escape time will be missed. [0003] Therefore, it...
