Abstract

Disclosed is a spring-ejection hammering type glass breaker with a pulling rod. According to a spring hammering manner, a spring is pressed and stressed under action of a level and then released instantly so as to generate a high-strength impact force to break armor glass. A fixed base with a rubber layer is adopted; during use, the base is pressed to the glass, the rubber layer is attached to the glass under air pressure, the pulling rod which is connected with a linkage rod is pulled, and the tail of the linkage rod clamps an operating rod through a clamping groove; as the head of the operating rod is of a sharp design and the operating rod is connected with the spring, the pulling rod can drive the linkage rod to lift to a certain height, the operating rod is released after the linkage rod is released from a V-shaped groove and strikes back at a high speed under ejection of the spring, a hammer is then driven to impact on the glass, so that the glass is broken by strong force, and the breaker separates from the glass after air enters the base. Any non-bulletproof tempered glass can be broken according to different designs of the length of the linkage rod and the strength of the spring.

Description

Pull rod-type and launch hammering glass breaker

Technical field:

Machinery, security protection, escape.

Background technology:

Along with the increase of number of vehicles, the increase of various mobile unit, the generation of this car accedent also becomes more frequent.Safety hammer also becomes and is more and more paid attention to.Such as, bus is just force and must be equipped with safety hammer without exception, especially air-conditioned coach, this kind of car is for bubble-tight requirement, often design and installation double strength glass, this vehicle, once have an accident, namely convinent car has outfit safety hammer, and will be escaped by broken glass when passenger escapes often is difficult to accomplish.Reason is, this accident has sudden, and how these passengers are first time experience, and meeting this accident all can be muddled.The safety hammer that present stage uses needs certain arm strength, hammering angle, hammering region, and these look to require easily then can become when accident occurs at ordinary times and are difficult to.The first, accident belongs to few probability event, and most people have and listened, but do not live through, and met appointment flurried, this safety hammer did not also use at all times, and one runs into accident, was also difficult to accomplish above 3 points.Come, because the overburden use often of existing vehicular traffic, such as, bus, at peak load conditions on and off duty, car door has all been crowded with substantially, and this situation makes once go wrong, and the passenger in car is difficult to move again.These 2 just illustrate, if safety hammer drops in child's hand, or in woman's hand, this people is ignorant of handy, then other people are difficult to help theirs.These can find from social concrete instance, substantially bus burst is on fire, now, what can jump that window escapes is all the man that leans on fist, pin substantially, smash glass escape, on safety hammer is useless on the contrary, and those people used are because using method mal, also glass could not be broken.The result of this practical operation shows, in accident, the flurried meeting of passenger becomes a kind of instinct, and the design of safety hammer also should meet passenger can proper operation under the effect of instinct.Otherwise it is useless that safety hammer will be made to put at ordinary times, time do not play effect.

Summary of the invention:

According to analysis, the hammering angle of safety hammer is fixed, adopts the mode of impact indirectly, select a pedestal, reserved punching hole, ensure that the angle of impact is vertical.In the selection of hitting region, use high force blow assistive device, glass breaking can be realized by the mode improving impact dynamics, this needs a kind of lever force, adopt the principle of lever to improve impact dynamics, so, break process can be carried out from any one region to case hardened glass.This three is combined, solve cause because the nervous and stream of people is crowded cannot the problem of broken glass in time.Make operation quite simple, only need one to draw gently, just can complete glass breaking, make the arm strength such as schoolgirl and child deficiency person can pound window fast equally in danger.

Detailed description of the invention:

One, pedestal is fixed, adopt the broken pedestal of absorption type, this pedestal designs with smooth type, rear embedding soft rubber smooth treatment, global shape is a strip shape character cut in bas-relief shape, coordinates hammering head to use, this pedestal is connected with destroyer, can by whole destroyer contacting without air thus being adsorbed on glass by bottom and glass.Two, draw-in groove joystick, one of this gangbar is designed to capitate, and is with pointed, and gangbar is strip shape, and is all with V-shaped draw-in groove in the bottom of both sides.Tup part and a brute spring of this gangbar lock.Three, elastic force squash type gangbar, this joystick is connected by positive and negative V word draw-in groove with gangbar, and gangbar length is greater than joystick, is provided with V-shaped spring leaf in edge termination.Gangbar is connected with joystick, pulls hand lever, and hand lever drives gangbar, gangbar drives control lever, and entirety pulls brute spring, and V-arrangement spring leaf slides in draw-in groove, when hand lever rises to certain altitude, V-arrangement spring leaf departs from joystick V-arrangement draw-in groove, and joystick is released, and joystick is fought back rapidly under the effect of brute spring, impact recess in the broken pedestal of spill, contact with case hardened glass, the brute force producing moment is hit, shattered glass.After glass is crashed to pieces, air enters absorption type pedestal, and pedestal departs from broken glass.Hold hand lever to push away forward, directly push glass fragment open.Complete glass breaking overall process.

At ordinary times, this is pulled rod-type and launch hammering glass breaker and be adsorbed on window edge, hand lever of directly leaving behind during use can complete glass for vehicle window fragmentation, convenient rapid again.After fragmentation completes, only need by this destroyer by an other sheet glass, now, absorption type broken pedestal extruding air, be adsorbed on glass, by pull rod-type launch hammering glass breaker hand lever reply initial position, V word spring leaf enters in V-arrangement draw-in groove, the more drop-down fragmentation that once just can complete second block of glass.Without the need to selecting any angle, optional hitting region, all can complete the brute force of any non-ballistic resistant function non-multilayer glass for vehicle window broken, comprise front windshield.
