Problems solved by technology

However, the space in the car itself is small, and there is a great obstacle in swinging a hammer, especially a small-mass hammer, which requires more space to swing; also, no matter how large the space for swinging a hammer is, a person with little strength can basically break it with a safety hammer. There is no glass; and the safety hammer is hung on the car, and the situation of loss often occurs. When an accident occurs, a large number of casualties cannot be avoided, and the safety hammer cannot play an emergency role very well.

Embodiment 1

[0034] Such as Figure 1 to Figure 4 As shown, a tempered glass crushing device includes a base 1, a support base 4, a crushing column 2 and a ratchet mechanism. The base 1 is flat, and the support base 4 is fixedly connected to one end of the base 1 .

[0035] The supporting base 4 , the crushing column 2 and the ratchet mechanism are all located on the same side of the base 1 . The supporting surface of broken column 2 vertical support seat 4 is set so that broken column 2 forms vertically with the broken surface of tempered glass 12 after tempered glass 12 is supported on support seat 4, certainly broken column 2 also can be with tempered glass 12 They are relatively inclined, that is, the crushing column 2 is inclined relative to the support seat 4, as long as the purpose of crushing the tempered glass 12 can be achieved. Of course, when the crushing column 2 is set perpendicular to the tempered glass 12, it is most labor-saving. Therefore, in this embodiment, The suppor...

Embodiment 2

[0045] Such as Figure 5 to Figure 9 As shown, a tempered glass crushing device includes a base 1 , a support base 4 , a crushing column 2 , a ratchet mechanism and a gear 15 . The base 1 is flat, and the support base 4 is fixedly connected to one end of the base 1 to form a T-shaped structure with the base 1 . The crushing column 2 and the gear 15 are located on the same side of the base 1 , and the ratchet mechanism is located on the other side of the base 1 . The supporting surface of the vertical support seat 4 of the crushing column 2 is set, the end of the crushing column 2 close to the support seat 4 is the working end, the end point of the working end of the crushing column 2 is point-shaped or linear, and the end point of the working end of the crushing column 2 is made of tempered glass 12 is made of harder materials.

[0046] The projection of the working end of the crushing column 2 to the direction of the supporting surface of the supporting seat 4 is located wi...

Embodiment 3

[0054]Since the breaking column of the present invention requires a relatively small linear motion stroke for breaking the tempered glass, that is to say, the linear velocity of the ratchet or the gear that drives the breaking column is relatively small. Therefore, it is only necessary to swing the active swing lever relatively A small angle can achieve the purpose of breaking tempered glass. In this embodiment, compared with Embodiment 1 and Embodiment 2, the setting of the active pawl will be canceled, and the active swing lever will be fixed directly with the ratchet, so that the operating end of the active swing lever can be directly The ratchet is rotated, and the non-return ratchet still exerts its function of restricting the rotation of the ratchet. The purpose of the present invention can also be achieved.

Abstract

The invention relates to improvement of a tempered glass breaking device. The tempered glass breaking device comprises a base relatively fixed with tempered glass to be broken, a breaking column used for exerting static pressure on a breaking face of the tempered glass is arranged on the base, the end, close to the tempered glass, of the breaking column is a working end, and a mechanical drive mechanism driving the breaking column to exert static pressure on the breaking face of the tempered glass is further arranged on the base. The mechanical structure is adopted, static pressure is used for quickly breaking the tempered glass, and strength for operating the device is little; in addition, the device and the tempered glass before breaking are relatively fixed, and the tempered glass can not be easily stolen.

Description

technical field [0001] The invention belongs to the field of glass breaking, and in particular relates to the improvement of a toughened glass breaking device. Background technique [0002] Tempered glass is obtained by cutting ordinary annealed glass into the required size first, then heating it to about 700 degrees close to the softening point, and then cooling it quickly and uniformly (usually 5-6MM glass is heated at 700 degrees for about 240 seconds, Cool down for about 150 seconds. 8-10MM glass is heated at a high temperature of 700 degrees for about 500 seconds and cooled for about 300 seconds. In short, depending on the thickness of the glass, the time for heating and cooling is also different). After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which improves the bending and impact strength of the glass, and its strength is about four times that of ordinary annealed glass. The tempered glass tha...
