Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

As shown in fig. 1 and 2, the utility model relates to a broken window ware of moving vehicle, casing 1 comprises shell 11, protecgulum 12, back lid 13, and casing 1 is inboard at the automotive glass through establishing stationary blade 111 vertical fixation on shell 11, and protecgulum 12, back lid 13 spiro union are equipped with interior bushing pipe 2 in shell 11 at shell 11 both ends, establishes exterior liner pipe 3 at the outside movable sleeve in interior bushing pipe 2 rear end, establishes gunpowder 8 in interior bushing pipe 2 rear end. The striker 4 is movably disposed in the outer liner 3, as shown in fig. 4, the striker 4 is composed of a needle point 41, a needle cap rim 42, a needle cap top 43 and a needle cap groove 44, the needle cap rim 42 abuts against the upper end portion 32 of the outer liner, and the needle cap top 43 extends out of the outer liner 3 and the rear cover 13. Be equipped with the dead man 6 of one end rotatable fastening at the back lid 13 on the back lid 13, dead man 6 can block and establish in needle cap recess 44, establish spring 5 in the 3 overcoat of bushing pipe, spring 5 supports respectively and establishes top in bushing pipe front end edge 31 and back lid 13, still is equipped with the trompil on the back lid 13, a diameter is greater than this trompil steel ball 9 and establishes in back lid 13, steel ball 9 one end stretches outside the 13 trompil of back lid and supports and establish in the relative needle cap top recess 44 of pole 6 outside, steel ball 9 one end top is established on the spring 5 of the 3 overcoat of bushing pipe established. The steel ball is skillfully arranged on the spring 5 to prop against the rod 6 to play a role of safety, and the rod cannot be opened by general random actions.

As shown in figures 2 and 3, the window breaking head is a high-strength metal nail 7, a metal cap 721 of the metal nail 7 is pressed against the gunpowder 8, an annular metal sheet 71 is welded at the front end of the metal nail 7, the metal sheet 71 is arched inwards to play a role of buffering and limiting when being fired, and the edge of the metal sheet 7 is clamped between the lining pipe 2 and the cover 12. The utility model discloses the metal peg is fixed a position by sheetmetal and interior bushing pipe, can not take place the skew, (vibrations can make general broken window head deflect when traditional broken window ware vehicle starts, and the resistance of increase can reduce the impulsive force of broken window head, if broken window head takes place great deflection, then there is broken window head to probably block, causes the bore of explosion), simultaneously the utility model discloses there are inside and outside two-layer structure, just can less inch make the broken window ware of big impulsive force, still need sheetmetal 71 to cushion even.

As shown in figure 5, in a firing pin firing state, the pulling rod 6 is pulled to be separated from the cap groove 44, the firing pin 4 is not limited and restrained, the spring 5 drives the outer liner tube 3 to further drive the firing pin 4 by the outer liner tube 3, and the needlepoint 41 of the firing pin 4 rapidly penetrates the gunpowder 8 through the firing pin through hole 21 of the inner liner tube 2 to explode the gunpowder.

As shown in FIG. 6, in order to achieve the state that the window breaker is fired after the gunpowder is ignited, the impact force of the gunpowder acts on the metal cap 71 to shoot out the metal nail 7 at a high speed, the metal nail 7 is separated from the metal sheet 71 which is originally fixedly connected with the metal nail and then extends out of the pinpoint through hole 121 of the front cover 12 to break the glass, finally, the metal cap 72 is blocked by the metal sheet 7 to prevent the metal nail from being shot again, and the arch of the metal sheet 71 is flattened after the buffering effect is achieved.

By controlling the amount of the propellant and the precision of components, the lowest impact force of the tip of the metal nail 7 is 1100N during testing, and the thickness of the part of the metal nail 7 extending out of the shell is set to be larger than that of the window glass, so that the metal nail can be broken even if double-layer glass or laminated glass is used for high-end vehicles.

The shell pressure relief holes 12 and the inner support column pressure relief holes 31 which are staggered in position are respectively arranged on the side walls of the shell 1 and the lining pipe, and the impact force generated by gunpowder is sprayed out through the two pressure relief holes, and meanwhile, the effect of silencing is also achieved. The two pressure relief holes are staggered to reduce the impact of gunpowder and protect users.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent shapes or structural changes made by the contents of the specification and the drawings or directly or indirectly applied to other related technical fields are included in the same way in the protection scope of the present invention.
