Description

A kind of one hand double hit formula window breaker

Technical field

The utility model belongs to window breaker technical field, and is related to a kind of singlehanded double hit formula window breaker.

Background technique

High-strength armoured-glass is widely used in various vehicles.Meanwhile glass curtain wall, glass window are in case of emergency Also the exit passageway as people's emergency evacuation escape.In the prior art, the window breaker in emergency circumstances used is general using peace Full hammer.

What is be mainly equipped in existing various types of vehicles is safety hammer, safety hammer be usually fastened on it is spare near glass for vehicle window, However when emergency occurs, people are not easy to rapidly remove safety hammer among flurried, meanwhile, the knot of safety hammer itself Structure is certainly reliable, but need when in use it is certain wave space and strength, do not received the general passenger of special training urgent In the case of probably due to operating space is limited, misoperation causes bad using effect.With advances in technology, in recent years Come, it has been developed that the more advanced mechanical spring handle type window breaker of all kinds of technologies.

Such as: Authorization Notice No. CN203542547U, the Chinese patent of entitled " handle type window breaker " disclose one kind Handle type window breaker, including hollow window breaker shell, the shock spring being arranged in window breaker shell hollow structure, shock group The shock component handle trigger device of component movement is hit in part and triggering；The component that collides includes that trip rod and setting are being hit The impact block of bar front end, the impact block are in triangular pyramid, and any one side of impact block is fixedly connected with trip rod, impact block Front end window breaker shell on be provided with impact block outlet, be provided at least two groups support base on the inner wall of window breaker shell, hit It hits bar to be fastened on support base, the rear end of trip rod is fixedly connected with the one end for hitting spring, and the other end for hitting spring is fixed It is connected on window breaker shell.Structure is simple, be conducive in use it is anti-lost, obtain good crushing effect and grasp Make simple.It is used and is more convenient certainly using such handle type window breaker, but its every " loading " is once, hitting bar " can only fire " one Under, and both hands compounding practice is wanted when " loading ", obvious efficiency and safety be not also in the emergency escape that must be raced against time Enough height.

For the efficiency and safety for further increasing brokenly window, it has been developed that with the height of singlehanded just achievable broken window operation Imitate window breaker.

Such as: open (bulletin) number are as follows: CN207221132U, entitled " a kind of to reset convenient efficient window breaker " China A kind of convenient efficient window breaker of reset is disclosed in patent, structure is as shown in Figures 1 to 4, including hollow shell 3, sets Set the shock spring 7 in shell 3, hit bar 17 and be arranged in hit the wherein one end of bar 17 cone cell hit block 8, the movement of bar 17 is hit in triggering Trigger device；Shell 3, which is equipped with, hits block outlet 4, is provided with support base on the inner wall of shell 3, hits with what shock spring 7 was connect 17 activity of bar is embedded on support base；It is also movably set with the magnet block 15 connected by pull rod 2 on support base, hits the another of bar 17 One end is connected with round block 16, and round block 16 is iron round block 16；The trigger device is magnetic-type trigger device, and pull rod 2 passes through drawing Moving magnet block 15, which is attracted, pulls the pulling of round block 16 to hit 17 compression impact spring 7 of bar, when the compressed elastic force for hitting spring 7 is big When magnetic adhesion between magnet block 15 and round block 16, after magnet block 15 and round block 16 are detached from, hit spring 7 and hit 17 elastic force of bar Push connection.

The whole outer profile of the shell 3 is the sub-assembly shape of ring block and cylindricality block, and one end of cylindricality block is along annular A radial direction and ring block integrally connected for block, the top of cylindricality block is protruded into the inner ring of ring block；The annular solid on sub-assembly top Portion is set as handle 1；The whole inner cavity of the cylindricality block portion of sub-assembly lower part sets point inner cavity for having three sections of reducings coaxial, from up to Under be followed successively by the maximum upper impression 12 of internal diameter, internal diameter secondly big medium-sized chamber 13, the smallest lower impressions 14 of internal diameter；Oblate cylindricality circle Block 16 is located at the top for hitting bar 17, and the diameter of round block 16 is suitable with the diameter of medium-sized chamber 13, and the bottom end for hitting bar 17 is equipped with catch spring part 18, the diameter of catch spring part 18 is suitable with the diameter of lower impressions 14, and the coniform block 8 that hits is located at 18 bottom surface of catch spring part, lower impressions 14 The bottom face of bottom surface and cylindricality block is located at same plane and is set as hitting block outlet 4；Between 14 top of medium-sized 13 bottom of chamber and lower impressions Equipped with diameter and the comparable first port of diameter for hitting bar 17, the top for hitting bar 17 passes through first port and protrudes into medium-sized chamber 13, round block 16 It is movably arranged in medium-sized chamber 13, covers and be located in lower impressions 14 in the shock spring 7 on the body of rod for hitting bar 17；Upper impression 12 is in Type chamber 13 is stepped straight-through, and the top surface of upper impression 12 is equipped with baffle ring 11, and second port is offered on baffle ring 11, and pull rod 2 passes through second Port protrudes into the bottom surface of upper impression 12, and diameter and the magnet block 15 of the comparable oblate cylindricality of 12 diameter of upper impression are located at 2 bottom of pull rod End, the top of the pull rod 2 protruded into the ring of ring block is horizontal to put down to the knob handle 5 for being equipped with staight shank shape, is arranged with setting on pull rod 2 and exists Reset spring 6 in upper impression 12；It hits bar 17 and is greater than medium-sized 13 bottom surface of chamber to the bottom end of cylindricality block with the total length for hitting both blocks 8 The spacing in face.

The reset is knob handle 5 in non-driving status, and reset spring 6 drives magnet block 15 and round block 16 to be attracted company It connects.

The shell 3 is that composition is fastenedly connected after the injection molding part pairing set by two to subdivision, two injection moldings The corresponding position of type part is respectively equipped with corresponding butt hole 10, and two injection molding parts pass through corresponding docking by corresponding bolt Hole 10 is fastenedly connected.

The outer periphery hoop of the bottom of the cylindricality block is equipped with the ring set 9 of reinforcing.

Using the efficient window breaker of the singlehanded just achievable broken window operation of such technology, one-handed performance can be completed any time " loading " and " percussion ", in the emergency escape that must be raced against time, obvious efficiency and safety are further enhanced.

But disadvantage is that: the efficient window breaker be able to achieve one-handed performance can complete any time " loading " and The key of " percussion " function is the magnetic adhesion being utilized between magnet block 15 and round block 16, but in case of emergency efficiently broken window Device periphery is likely to occur state on fire, and high temperature is possible to that 15 loss of excitation of magnet block can be made to make the efficient window breaker lose Function, reliability is high not enough, this is the security risk that must overcome, therefore it must be further improved.
