Description
Technical field
The utility model relates to automobile safety field, escape device in the car particularly relating to a kind of self-propelled vehicle.
Background technology
Safety hammer is waited for bus as a kind of bus, school bus the escaping tool of interior necessity, is widely adopted and approves.But common conventional security hammer exists a lot of problem in use, to cause when causing danger situation use safety hammer can not in time and effectively vehicle window smashing and escaping.In recent years, when automobile has an accident, the situation losing escape chance because not opening vehicle window frequently occurs.The on-vehicle safety hammer that present stage generally uses, mainly escape with toe shattered glass, there are some remarkable shortcomings in it, one is that most people do not know knock the concentrated vehicle window corner of stress with safety hammer, and goes to knock the window heart be not easily crashed to pieces in use.In addition, on school bus, touristy coach are waited for bus, the upper limb of vehicle window is blocked by baggage rack, and lower edge is blocked by seat, so there is no the suitable acting point of hammering vehicle window corner, can only select the window heart be not easily crashed to pieces.Two is crowded in a hurry in car when causing danger, and user does not have enough spaces to stretch one's arm and enough buffer distances, thus makes hammering strength too small and not easily shattered glass.Three is that safety hammer is placed directly in vehicle window side, easily loses.Four is that when causing danger use safety hammer, hammer force is often not vertical with glass surface, and direction and the glass surface of power have angle of inclination, hammer force are had a greatly reduced quality, not easily shattered glass.Five is when having an accident, and people big city exists terrified mood, worries that use safety hammer hammering glass can be scratched arm by glass fragment, may can not vehicle window smashing rapidly because of psychological factor when therefore knocking vehicle window.In addition, for China Patent Publication No. 103770738A, publication date 2014.05.07, invention and created name is that ejection type fixes window breaker, that application discloses a kind of ejection type and fixes window breaker, comprise base, fix screw, support back seat, torsion spring, swivel arm, safety plug, draw ring, hits nail.Base is fixed on glass for vehicle window outer ledge corner by fix screw, base rear end connects support back seat, pan frontward end connects torsion spring, torsion spring upper end connection of rotating arm, the two ends of torsion spring are separately fixed on base and swivel arm, and safety plug is through supporting the through hole of back seat and the through hole of swivel arm, above swivel arm, draw ring is installed, install below and hit nail, hit nail and aim at glass for vehicle window corner, described hits nail front end for conical.Find its weak point through model experiment, first is this device when being fixed on window frame of automobile, and because the glass of different automobile types is different with the spacing of window frame of automobile, the height hitting nail cannot adjust, and it can not be made to contact with glass surface, so can not mate various vehicle.Second is hit that to follow closely the part of stretching out long, on the one hand when nail tip is subject to the power of direction perpendicular to screw rod, hits maximal bending moment that nail and screw rod rigidly connected cross section produce and easily makes to hit to follow closely and rupture, and another aspect is hit and followed closely long, increases cost.3rd be this invention torsion spring on leg and lower support leg be stuck on swivel arm and base, in addition torsion spring does not have other fixation, and when pull-up swivel arm, the easy slippage of leg of torsion spring comes off, and effectively can not break window.4th is when glass for vehicle window has angle of inclination, and the angle of swivel arm can not adjust thereupon, hits nail and can not vertically to conflict glass for vehicle window face.5th be the position of torsion spring in bearing front end, cause effective arm of force too short, overcome pulling force required for spring moment of flexure and increase, cause old man and women and children can not pull-up knob easily, therefore effectively can not break window.6th is that the window frame of automobile that has is narrower, and the part that the base of this device stretches out bearing is comparatively large, and base cannot be fixed, and takies larger space.
Summary of the invention
Technical problem to be solved in the utility model be to provide fast, the broken window success ratio of a kind of toggle speed high, be not easy to lose, escape device in a kind of cup dolly fixed type car of little, the safety and stability of taking up room.
The utility model solves the problems of the technologies described above adopted technical scheme: escape device in a kind of cup dolly fixed type car, by knob, nut, screw rod, hit nail, swivel arm, safety plug, torsion spring, pin, bearing, socket head cap screw, cup dolly, spiral nail forms, it is characterized in that, knob is spun by screw thread and screw rod upper end, screw rod is spun by screw thread and swivel arm front end, and nut sleeve, on screw rod, is positioned in the middle of swivel arm and knob, hit nail and be embedded in screw rod lower end, hit the conflict glass for vehicle window face, tip of nail, swivel arm rear end is fixed by pin and bearing, and pin is through bearing, torsion spring, swivel arm, safety plug is through bearing, swivel arm, the upper leg of torsion spring is stuck on the inwall of swivel arm, the lower support leg of torsion spring is stuck in the groove on bearing, bearing lower end is fixed on cup dolly, socket head cap screw is threaded connection bearing and cup dolly, the bottom contact swivel arm of socket head cap screw, cup dolly is fixed on window frame of automobile by spiral nail.
The described material hitting nail is hard alloy.
Described bearing and knob are refractory material.
Described cup dolly is refractory material.
Described cup dolly is fixed by four spiral nails and window frame of automobile.
When this device is installed, the spacing size adjustment screw rod height according to window frame of automobile and glass for vehicle window face makes to hit nail tip end conflict glass for vehicle window face, and then fastening nut makes screw rod be stabilized on swivel arm.Regulate socket head cap screw that swivel arm is rotated according to the angle of inclination of vehicle window, allow and hit the vertical glass for vehicle window face of nail.
During situation of causing danger, pull out safety plug, pull-up knob, until the elastic limit of torsion spring, is then loosed one's grip, and the elastic force of torsion spring makes to hit nail and clashes into glass and shattered glass.
The utility model has the advantages that:
1. compared with hammering into shape with use safety, this device is fixed on window frame of automobile, and the rum point hitting nail aims at the concentrated position of glass strain, easy shattered glass, and device is fixed, be not easy to lose, the force that pull-up swivel arm needs is apart from short, run up time is short, and after shattered glass, fragment not easily splashes and hurts sb.'s feelings.
2. the utility model uses the structure of screw rod and nut, and when the glass of different automobile types is different with the spacing of window frame of automobile, the height hitting nail can regulate, and is conflicted in itself and glass for vehicle window face.
3. the nail that hits of the present utility model is embedded in screw rod, and the part of stretching out is very short, when nail tip is subject to the power perpendicular to screw rod, hits and follow closely not easy fracture when being subject to clashing into, simultaneously cost-saving.
4. the upper leg of torsion spring and the lower support leg of torsion spring are stuck on swivel arm and bearing, and pin is through bearing, torsion spring, swivel arm, and torsion spring is stabilized on bearing when reversing, and when pull-up swivel arm, the leg of torsion spring is not easy slippage and comes off.
5., when glass for vehicle window has angle of inclination, by turn-knob socket head cap screw, the angle of swivel arm can make thereupon adjusting to hit the vertical conflict glass for vehicle window face of nail.
6. the position of torsion spring is at base rear end, effective force brachium, and the pulling force overcome required for spring moment of flexure is little, and old man and women and children can pull-up knobs easily, and successfully the probability of broken window escape is large.
