Description

Double-layer toughened glass window breaker

The technical field is as follows:

the invention relates to the field of public safety, in particular to a double-layer toughened glass window breaker.

Background art:

the existing window-breaking escape tools have various types, such as: the window-touching hammer is commonly arranged on a bus, and in addition, the window-touching hammer also comprises a plurality of centralized control type electric window breakers and other manual window breakers. However, all of these methods are either not effective or rely on other conditions (such as electricity or gas) to operate, and most of them break only a single layer of toughened glass.

In recent decades, due to the driving of high-speed rail and the wider application of luxury buses, more and more windows of vehicles adopt double-layer toughened glass. However, there are few and few window breaking tools available for breaking double-layer tempered glass.

The inventor of the present invention, after carefully reviewing the existing data, only provides the following two examples for the examiner to refer to:

first, the application number is CN201720787187.3, granted patent, its main characteristic is: a sliding groove with pressure and a box are arranged on a window frame, and then a main body of the window breaker is supported to the surface of the inner glass through a connecting component, the inner glass is broken in a pressing mode, and then the outer glass is broken by pressing again. Although the scheme can also achieve the purpose of breaking the double-layer glass, the structure is complex, the number of parts is large, the volume is too large, and the use of other facilities such as curtains is influenced.

The second step is as follows: the patent with the application number of CN201620944502 is characterized in that the inner and outer layer glass is clamped inside the window breaker by the main body of the window breaker through a mounting bolt, a 'micro gas generator' is mounted, and then automatic window breaking is realized by connecting a signal cable, a power supply igniter and the like.

However, this solution has the following two disadvantages: firstly, the bolt hole must be reserved for installation when the vehicle is manufactured, so that the bolt hole is not suitable for a large number of vehicles in use, secondly, the structure is very complicated, and the use of cables, igniters and the like increases the manufacturing cost and the later maintenance cost.

The invention content is as follows:

the invention aims to solve the problems and provide a manual window breaking tool which has a simple structure, reliable action, long service life and easy operation, and can be used for both single-layer glass and double-layer (multi-layer) toughened glass. In order to achieve the purpose, the technical solution of the invention is as follows:

a double-layer toughened glass window breaker comprises an elastic arm plate 1, an impact plate 2, an impact steel needle 3, a safety pin 4 and a mounting screw 5:

the method is characterized in that: the elastic arm plate 1 is made of any material which has elasticity and can be bent towards the striking direction after being struck by common palm force; one end of the impact plate is fixed on a frame at any position of the inner side of the car window, and the other end of the impact plate is fixedly provided with an impact plate 2; one end of the impact plate 2 is provided with an impact plane 2-1 with a larger area, and the other end is fixedly provided with an impact steel needle 3; one end of the impact steel needle 3 is sharp, and the sharp end is vertically directed to the inner window glass 5; one end of the safety pin 4 is provided with an elastic opening 4-1, and the other end is provided with a closed finger ring buckle 4-2; and is mounted between the elastic arm plate 1 and the inner glazing 5; the thickness of the elastic opening 4-1 is more than or equal to the distance between the tip of the impact steel needle 3 and the elastic arm plate 1.

The invention is characterized in that: it has utilized the stability that the inherent rigidity of elasticity armed plate 1 provided, supports at ordinary times and fixes and strike steel needle 3 and be in reasonable broken window position, for conveniently breaking inboard glass 5 and provide the condition, ingenious again has utilized another kind of characteristic that elasticity armed plate 1 had simultaneously, promptly: the device has the characteristic that the impact steel needle 3 is naturally driven to be close to the outer glass 6 due to the bending and deformation of the external force caused by the beating of the palm of a user, and the device is ready for breaking the outer glass 6, so that the user does not need any redundant action and can achieve the purpose of quickly, stably and reliably breaking double-layer (or multi-layer) glass only by continuously beating the impact plate 2 under the guidance of the subconscious action. Provides conditions for realizing quick escape.

Description of the drawings:

the figure is a schematic view of the structure and the installation method of the invention.

The second figure is a schematic diagram of the safety pin structure in the invention.

Wherein: 1 is an elastic arm plate, 2 is an impact plate, 3 is an impact steel needle, 4 is a safety pin, 5 is inner glass of a door or a window, 6 is outer glass, 7 is a frame of the door or the window, and 8 is a mounting screw.

The specific implementation mode is as follows:

the following embodiments are given in conjunction with the accompanying drawings:

as shown in the figure, the elastic arm plate 1 is fixed at a proper position of the window frame 7 by screws 8 (the best position is the upper part), the elastic arm plate 1 is made of a material which has certain strength and can generate certain deformation after being hit by palm force of a hand (the best material is a stainless steel plate), the length, the width and the thickness of the elastic arm plate 1 are adapted to the requirements, the other end part of the elastic arm plate 1 is provided with the impact plate 2, the cross section of the impact plate 2 is in a T shape, the outer side of the impact plate is provided with an impact plane 2-1 with a larger area for bearing the hit of the palm force, and the best material for manufacturing the elastic arm plate is plastic. The impact steel needle 3 is mounted on the inner side of the impact plate 2, and the sharp end of the impact steel needle points to the inner glass 5. The best mounting is a fixed combination. The impact steel needle 3 is made of a metal material with hardness higher than that of tempered glass, and the best material is manganese steel or tungsten steel. The safety pin 4 is arranged between the elastic arm plate 1 and the inner glass 5, the thickness of the elastic opening 4-1 of the safety pin is more than or equal to the distance between the elastic arm plate 1 and the glass 5, the safety pin is used for preventing mistaken impact, and the optimal material of the safety pin is also plastic.

When the window needs to be broken to escape in an emergency, an escape person can insert fingers into the closed ring 4-2 of the safety pin and pull down the safety pin 4, at the moment, as long as the strength is large enough, the elastic opening 4-1 of the safety pin can be bounced and fall off, at the moment, the impact plate 2 is hit inwards by a palm, the sharp part of the impact steel needle 3 can impact the surface of the inner glass 5, the inner glass 5 bursts, and at the same time, due to the inertia effect of palm flapping force, the impact steel needle 3 can naturally discharge broken glass fragments to reach the surface of the outer glass 6, and at the moment, due to the deformation of the elastic arm plate 1, the steel needle 3 is supported to stay near the surface of the outer glass 6, so that conditions are provided for breaking the outer glass again. At this time, the user can continuously flap again by the subconscious and habitual actions naturally generated by the user in an emergency, and then the second layer or the third layer of glass can be continuously broken by the same process.
