Abstract

The utility model discloses an automatic safety hammer, which is capable of breaking glass under emergency condition and is formed by a square shell, a bottom plate, a hammer head, a gear group, a crankshaft connection rod, a bearing and a motor; a motor rotary shaft is connected with two grades of gear groups connected with the crankshaft connection rod; the crankshaft connection rod and the hammer head are connected to form a crankshaft slider mechanism; an air pressure port of the shell is connected with an air pressure pipe; the connection rod and the hammer head are parallel in horizontal direction and fixed in direction; and the connection rod can slide in a groove of the hammer head sliding in a guide hole. The rotary motion is converted into linear motion and through the crankshaft connection rod mechanism after the rotary speed of the motor shaft is subjected to speed reduction by the gear groups, so that a boosting effect is realized. When a fire or other disasters occur to a vehicle, s switch is pressed down, the safety hammer is supported by an air pressure device, and the motor operates to break the glass of a vehicle window for helping passengers to escape.

Description

One-touch touch-control automation safety hammer

Technical field

The utility model relates to a kind of mechanical device of one-touch touch-control automation safety hammer, especially can in time smash the safety hammer of bus glass the bus Shi Nengwei passenger of burning.

Background technology

At present, the bus safety hammer of knowing takes common safety hammer shattered glass to win escape time by the passenger from skill.When bus generation spontaneous combustion, the passenger takes off the safety hammer of providing for oneself on the bus, firmly smashes the ad-hoc location of case hardened glass, after the glass fragmentation, jumps off escape from window.But common safety hammer exists to be lost easily, and the passenger can not use, the operating process very complicated, and a series of problems such as the position is fixing, especially in case of emergency the passenger is because of the panic or injured action that can't finish with conventional security hammering cullet.Therefore, research a kind of under unexpected situation automatically the safety hammer of shattered glass have very realistic meanings.

Summary of the invention

For when the bus spontaneous combustion, for better smoothly shattered glass win more escape time, this is practical to provide a kind of one-touch touch-control automation safety hammer, the shattered glass that this safety hammer can not only be accurately and timely and also can be after the bus spontaneous combustion shattered glass easily automatically.

The technical scheme that its technical matters that solves the utility model adopts is: one-touch touch-control automation safety hammer has adopted biswitch control system device, air pressure is propped up and the dead angle anchor fitting, the two-stage reduction gear apparatus, slider-crank mechanism, thus reach the effect of shattered glass.After the bus burning, under the manipulable situation of chaufeur, by the shift knob opening device of operator's compartment, and then open folding device, and then turn to bus glass over against direction.Can open motor automatically afterwards, driven gear underspeeds, thereby hangs one's head shattered glass with lower speed drive lever motion and then drive.This device also can adopt bus ceiling switch-starter to reach corresponding effect.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is bench section of the present utility model constructional drawing.

Fig. 2 is the axis block diagram that waits of the present utility model.

Fig. 3 is installation site of the present utility model line frame graph.

Fig. 4 is electrical equipment control figure of the present utility model.

The specific embodiment

In Fig. 1, motor shaft 1 and gear 1 are connected by flat key, gear 2 is realized reduction of speed with gear 3 engagements, and gear 3 links to each other by flat key 4 with S. A., and gear 6 is realized reduction of speed with gear 8 engagements, crank 7 and connecting rod 9 link to each other by revolute pair, connecting rod 9 and vertical rod 10 be by flat strong forming a fixed connection, and connecting rod 9 and tup 12 are parallel and direction is constant always in the horizontal direction, and tup 12 slides in pilot hole 13, bearing 11 can slide in the tup groove, and bearing 5 is used for supporting turning cylinder.2 rotations of motor shaft 1 driven gear, by gear 2 and gear 3, gear 6 is realized reduction of speed with gear 8 two-stage gear combination transmissions, by the slider-crank mechanism formed by crank 7, connecting rod 9 and tup 12 rotatablely moving of gear 8 is converted into the straight-line motion of tup 12 again, realizes impacting the action effect of glass.

In Fig. 2, safety hammer is installed on the other side plate 1 of glass, pneumatic shuttle props up the safety hammer base plate by air pressure communication port 2 and shell 3 makes tup over against glass, and connecting rod 5 forms the dead angle anchor fitting with connecting rod 4 lucky in-lines simultaneously, thereby realizes the effect of shattered glass.

In Fig. 3, tup slides in slideway 1, and base plate 3 is installed on the other side plate of glass, and electrical motor 2 is for generation of rotatablely moving.

In Fig. 4, electric system uses the 24V vdc.In emergency circumstances, the driver presses switch 4 or the passenger presses switch 5, and at this moment, relay coil 1, time-delay 5s disconnect relay coil 2, time-delay 2s cutin relay coil 3 simultaneously, open contact 1 action is closed, pneumatic shuttle 6 is propped up safety hammer, and 2s often opens time-delay make contact 3 closures after the time, described one-touch touch-control automation safety hammer motor 7 energising runnings, thereby shattered glass, time-delay disconnects 2 disconnections of relay normally closed contact behind the 3s, and the total system outage quits work.

Claims
