Description
Technical field
The utility model is related to a kind of ejection type safety hammers more particularly to one kind can be suitble to a variety of crowds all can very labour-saving
It breaks the safety hammer of glass for vehicle window into pieces, belongs to vehicle and multiply personnel safety appliance technology.
Background technology
On in the compartment of bus, large and medium bus or kart and high ferro, consider from safety, is both needed to match
A certain number of safety hammers are set, effect is when locating normally open the window in a dangerous situation, and hammer safe to use can smash
Vehicle window and escape rapidly, the safety hammer of traditional structure in use can because of underwater resistance, brandish that dynamics is insufficient, use space water
The factors such as foot cause to use upper inconvenience, quickly vehicle window purpose are broken into pieces in time so that being not achieved, delayed the best of escape
Time, therefore and cause unnecessary injury.
Insufficient space and the inadequate problem of dynamics are brandished for car, also has quite several Creative products to disclose.In such as
State's patent of invention " pulling-spring type safety hammer "（201410727056.7）Disclosed, it is to lead to safe hammer according to catapult principle
Sucker suction is crossed on glass for vehicle window, spring is installed between sucker and safe hammer, when use is caught draws outside the handle of safety hammer
It unclamps again, tup hits glass for vehicle window to broken；Its shortcoming, which is described device, to be adsorbed on glass for vehicle window, this is obviously not
It is the kart of Liftable type vehicle window suitable for the overwhelming majority；Similarly, patent of invention " a kind of spring-piece type safe escape hammer "
（201210086857.0）Similarly there is this kind of shortcoming；Patent of invention " a kind of safety hammer "（201010281663.7）It is public
Opened and be triggered by trigger, main spring elongation, push tup strike glass for vehicle window, and with brandish hammer handle generation impact force shape
At resultant force, the design that glass for vehicle window is smashed, but it is not likely to form resultant force impact effect in actually using, the reason is that main spring pushes away
Dynamic tup impact, which will necessarily lag behind, brandishes hammer handle stroke time, on the other hand, this brandish formula impact vehicle window also need it is enough
Brandish space；Patent of invention " brute spring trigger type automotive safety hammer "（201310018913.1）It is a kind of imitative pistol type knot
Structure, it is anticipated that though cocking has good effect when striking vehicle window, if a miss, when recovery then needs two hands to match
Conjunction can just make tup return, and enough strength is needed when return, this obviously and is not suitable for women and children；Patent of invention
" a kind of powerful vehicle-mounted safety hammer "（201110407639.8）Though vehicle can be smashed by spring energy-storage, quantitative automatic release, completion
Window acts, but device equally needs both hands to operate, and needs the strength of foot that could complete spring energy-storage, and being unsuitable for women and children makes
With if there is energy storage not at vehicle window scheme can not be struck by the spare mode of brandishing.
Invention content
The utility model aim is to be directed to background technology described problem, designs a kind of ejection type safety hammer, is passed using connecting rod
Dynamic structure can generate very powerful impact force by its internal high compression spring when mediating trigger, can also Reusability,
Its structure is similar to manual air nail gun, by percussion hammer portions proximate glass when use, it is only necessary to mediate trigger, pass through the elasticity of spring
Potential energy drives internal mechanical structure, so that percussion hammer is hit rapidly, break glass, for when escape strives for valuable in traffic accident
Between；Even the smaller women of strength or children could be used that, before hitting in a flash, percussion hammer can also be produced due to internal structure
Raw rotation can reinforce the execution for hitting glass generation, and percussion hammer does not detach after hitting with hammer body, avoids meeting when idle
Accidentally injure oneself；Particularly, when spring failure, it also can be used as common taper nail hammer and use, brandish and strike vehicle window, it is ensured that peace
Vehicle window effect is quickly broken up entirely, it is simple in structure, highly practical, safe and reliable.
