Description
Technical field
The utility model relates to a kind of device of ride safety of automobile equipment technical field, specifically a kind of glass for vehicle window breaker for emergency situation.
Background technology
Along with environmental consciousness strengthens, mass transportation facilities is one of Green Travel instrument of actively advocating at present, but the confined space that its inside is people is many, people is assorted, once have an accident, understands and lead to painful accident because of the difficulty of escaping.The report of a lot of public transport fire injures and deaths, startling in recent years, all mentions owing to can not opening the door in time or the escape of broken window in report, aggravated casualty numbers., also there is the situation that bus is not had by water logging in the heavy rain that National Day in this year, first working day, Shanghai met with later, not bad personnel evacuate already, can be more serious otherwise be trapped in water-bed consequence.
To the various safety methods compared with present track traffic aspect, the safety of mass transportation facilities more needs us to pay attention in fact.Floods and fires have no mercy, adds ground communications complexity, collides, overturns and be unavoidable, at this time just needs us to do one's utmost to pay close attention in compartment passenger's the unimpeded of path of escaping.But according to observations, the safety hammer that should lay on bus often " disappears suddenly ", be thisly fixed near safety hammer automotive window by simple button-shaped structure, owing to adopting the non-formula structure that is completely fixed, be easy to lose.On market, there are various glass breaking utensils now, all interosculate that is exactly handheld portable, although do safer and safer, do smaller and more exquisite and smaller and exquisite, but just fearness in case of emergency can not find at once, Here it is problem place.Can have so a kind of can fix device onboard can be in times of crisis broken glass quickly and effectively.
On bus, configure glass for vehicle window breaker necessary, but often " disappearing suddenly " of safety hammer on a lot of bus causes emergency situation cannot pound cullet escape.
Through the retrieval of prior art is found, Chinese patent literature CN102923087A, open day 2013.02.13, a kind of vehicle escape hammer is disclosed, mainly comprise drive crank, knock bar, knock hammer, driven rocking bar and energy stroage spring etc., and formation can be played the double rocker mechanism of speed amplification, with time drive drive crank by the elastic potential energy being stored in spring of abrupt release, drive is knocked bar and is rotated with very fast speed, be positioned at and knock knocking hammer and just, with very large speed shock glass port, making it in moment fragmentation of boom end.But the defect of this technology is to have used two rocking bars to connect quartering hammer motion, make to connect between rocking bar lubricated larger on actual beating effect impact; This technology may produce false triggering and the safety problem that causes in the time that structure angle is not considered automobile bumpiness simultaneously, and safety guard is not set.
Chinese patent literature CN202764906U, open day 2013.03.06, disclose a kind of glass for vehicle window breaker, formed by knocking parts 1, mounting seat 2 and spring 3, it is characterized in that: the described parts 1 that knock have been made up of connecting rod 11, rotating guide 12, draw ring 13 and taper tup 14; Described mounting seat 2 is formed by one flat plate 21, and its four jiaos of places are respectively provided with a mounting hole 22, also has four back-up blocks 23 on dull and stereotyped 21; Described spring 3 is installed on the rotating guide 12 that knocks parts 1, and one free end is fixed on rotating guide 12, and the other end is fixed on dull and stereotyped 21, and rotating guide 12 is through four back-up blocks 23.But the defect of this technology is: in the time of emergency situation, need people for pulling draw ring, then discharge shattered glass.When so usual state, quartering hammer is to contact with glass for vehicle window, easily at automobile shattered glass during at severe jolt; Owing to there is no safety device, easily allow people arbitrarily pull draw ring simultaneously, cause and discharge and triggering shattered glass.
Utility model content
The utility model, for prior art above shortcomings, proposes a kind of glass for vehicle window breaker, relatively fixes, can instantaneously trigger, the glass for vehicle window breaker of safety and effectivity.This device adopts torsion spring as power, in conjunction with rotating frame, guarantees crushing window glass at short notice; Adopt safety knobs and chute, can when emergency situation, pull the trigger rapidly crushing mechanism by chute, can device be fixed by safety knobs again, avoid automobile bumpiness and cause device to trigger.The experiment proved that, this device can smash 4mm, 5mm and 8mm glass rapidly.
The utility model is achieved through the following technical solutions: the utility model comprises: breaker framework, helical torsional spring and safety protection mechanism; wherein: breaker framework rotates to be arranged on glass for vehicle window and/or window frame and with safety protection mechanism and contacts, and helical torsional spring is wound on breaker framework and to breaker framework and applies torsion.
Described breaker framework is rectangle, semicircle or triangular structure; Breaker framework is provided with the hammer that attacks and destroy for shattered glass, preferably: breaker with attack and destroy hammer be integrated.
Described attacks and destroy hammer for bullet shaped structure, and the head end that attacks and destroy hammer is broken segment.
The torque peak of described helical torsional spring is no more than 3240Nmm, and working torsional angle degree is 70-100 °.The two ends of this helical torsional spring
Described safety protection mechanism is provided with and attacks and destroy the hold down groove that contacts of hammer, and this hold down groove is fixedly installed on safety protection mechanism by chute knob structure.When non-emergent situation, attack and destroy hammer be fixed in hold down groove, when emergency situation occurs, unclamp the fixing button in chute knob structure, remove hold down groove can make to attack and destroy hammer into shape be subject to helical torsional spring torsion overturn shattered glass.
Described breaker outside is provided with and prevents that glass is broken and spatter or the screened housing of children's false touch.
Technique effect
Compared with prior art, technique effect of the present utility model comprises:
1) use torsion spring, have durable, the shattered glass time is short;
2), by safety protection mechanism, usually also not producing triggering in automobile bumpiness process, use safety;
3) simple in structure, cost of manufacture is low, can carry out large scale application.
