Description

Automobile cab upset controlling organization safety lock

The utility model relates to a kind of automobile cab upset controlling organization safety lock, and it is applicable to the upset controlling organization of various cargo vehicle upset driver's cabins.

At present, the driver's cabin of the convertible structure of automobile is used for large-scale cargo vehicle mostly, with convenient for maintaining.The driver's cabin of this structure is fixed in the mode of lock clasp usually, promptly inserts firmly on the car body fixed support with the bearing pin in the upset controlling organization, and locking driver's cab turnover handlebar, automobile can cruising.But the driver forgets after repairing and inserts firmly bearing pin or other people arbitrarily extract bearing pin sometimes, easily causes the upset handlebar out of control, cause automobile in the process of moving driver's cabin overturn suddenly, major traffic accidents take place.

The purpose of this utility model just provides a kind of automobile cab upset controlling organization safety lock.Its compact conformation, volume is little, and is easy to operate, can effectively lock driver's cab turnover controlling organization handlebar, prevents from that the driver from forgetting to insert firmly bearing pin or other people arbitrarily extract bearing pin, thereby fundamentally stops the traffic accident that causes because of driver's cabin upset suddenly.

The purpose of this utility model is achieved in that this device comprises the bearing pin of lock core, lock body and locking driver's cab turnover controlling organization handlebar, wherein in the holder of bearing pin insertion end flexible springs is arranged, the lock core eccentric shaft drives slide plate and moves back and forth along lock body is upper and lower, and the slide plate upper end has can stretch into or withdraw from the fond of gossip of bearing pin draw-in groove.

Because the utility model adopts lock body and locks automobile cab upset controlling organization handlebar by the locking device that the bearing pin of lock core control is formed, so the traffic accident that driver's cabin overturns and causes suddenly can prevent to cause driving a vehicle because of maloperation the time.This bearing pin insertion end has the holder of band coil tension spring in addition, utilizes the elastic force of spring can lock or eject bearing pin.Block tongue on the eccentric shaft drive slide plate on the lock core stretches into or withdraws from the draw-in groove on the bearing pin, have only lock core to forward closed condition to, be that block tongue is when snapping in draw-in groove, just can take off key, can prevent from effectively that the driver from forgetting to insert firmly bearing pin, simultaneously key operated because of not having, other people can not arbitrarily extract bearing pin, therefore the utility model is safe and reliable, and this apparatus structure is simple, compact, volume is little, easy and simple to handle, is highly suitable in automobile cab and the railway carriage small space and installs.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation that the utility model is laid down anti-cover.

Fig. 2 is the vertical view of Fig. 1.

Lock body was laid down the structure of cover plate schematic diagram when Fig. 3 was the utility model closed condition.

Fig. 4 is the sectional view of Fig. 3 along the A-A line.

Lock body was laid down the structure of cover plate schematic diagram when Fig. 5 was the utility model opening.

Describe concrete structure of the present utility model and mode of occupation in detail according to Fig. 1-5, this safety lock is dimerous by locking device and device for ejecting.Wherein locking device comprises and utilizes junction plate 10 to be assembled in the lock body 8 on the cab turning mechanism support 2 and assemble parts such as lock core 9 in it, bearing pin 5, slide plate 11, cover plate 17.Device for ejecting comprises holder 3, the flexible springs 4 that is assembled on the support 2.Lock core 9 keyhole end are covered with protective cover 15, and are fixed on the lock body 8 with bolt 11, and this protective cover 15 adopts flexible materials, make as polyurethane etc.When opening lock, need not unload bolt 16 and can pull up protective cover 15.Go up protective cover 15 with finishing to cover immediately, to prevent advancing foreign matter or water in lock core 9 holes.Along lock body 8 left and right mobile bearing pin 5 one ends draw-in groove 18 is arranged, it axially has stopper slot 6, and by spacer pin 7 axial limitings on the lock body 8, the elastic force effect At time of eject of the compression spring 4 so that opening safety lock (as shown in Figure 5) bearing pin 5 is fixed in the seat 3 does not leave lock body 8.There is block tongue 12 slide plate 11 upper ends, there is tensioning torsion spring 14 lower end, it is drive lower edge lock body 8 upper and lower the moving back and forth of lock core 9 eccentric shafts 13, when moving up, block tongue 12 stretches in the draw-in groove 18 of bearing pin 5, and safety lock is in closed condition, when moving down, block tongue 12 withdraws from the draw-in groove 18 of bearing pin 5, and the insertion end that bearing pin 5 is positioned at holder 3 is ejected by its compression spring 4, and safety lock is in opening.This lock key and automotive ignition lock, door lock can shared same keys, also can be on same key ring with this lock key and automobile door lock, ignition lock string, and when lock was in opening, key can not take off.

When needing repairing automobile upset driver's cabin, take off protective cover 15, insert key, rotational lock core 9 drives slide plate 11 by its eccentric shaft 13 and moves down along lock body 8, and the block tongue 12 of slide plate 11 upper ends withdraws from the draw-in groove 18 on the bearing pin 5.Meanwhile, the insertion end of the bearing pin 5 compression springs 4 of seat in 3 that are fixed eject, and the handlebar 1 of switching mechanism gets final product operate as normal.Because of lock core 9 turns an angle, so key can not take out.

When needing the locking switching mechanism, end with hand propelled bearing pin 5 inserts holder 3, this moment, its interior spring 4 was compressed, and the draw-in groove 18 of bearing pin 5 is aimed at the block tongue 12 of slide plates 11 upper ends, and slide plate 11 moves up under the effect of tensioning torsion spring 14, block tongue 12 is snapped in the draw-in groove 18 of bearing pin 5, the handlebar 1 of locking switching mechanism, driver's cabin just can not overturn, and resets because of shipper pole movable lock core on the slide plate 11 9 rotates simultaneously, so can take out key, protective cover 15 on the cover.
