Abstract

The utility model discloses a combined type motor vehicle anti-theft lock. An arched deflector rod gyration groove is arranged in the rear of a lock tongue dialing piece connecting a lock and a lock tongue; an arched rod of an arched deflector rod is arranged in the arched deflector rod gyration groove; a spring fixed device is arranged on the left end of the lock tongue dialing piece which is arranged in the inner chamber of the lock body and can slide right and left along the lock tongue; a return spring of the lock tongue dialing piece is arranged on the spring fixed device; one end of the return spring is supported on the spring fixed device; the other end of the return spring is supported on the inner chamber of the lock body; a locked groove is arranged on the lock tongue; an electromagnetic switch is arranged on the lock body of the locked groove; a mounting hole of a telescopic locked pin is arranged on the lock body of the telescopic locked pin of the electromagnetic switch; the telescopic locked pin on the electromagnetic switch passes the mounting hole and corresponds to the locked groove. The utility model is a motor vehicle anti-theft lock with good anti-theft effect and a double anti-theft device.

Description

The combination motor vehicle theftproof lock

One, technical field

This use is novel to relate to a kind of anti-theft lock for motored vehicle, and it is applicable to the antitheft of motor vehicles such as motorcycle, automobile.

Two, background technology

At present, though anti-theft lock for motored vehicle is a lot, the lock core of these anti-theft lock for motored vehicle is easily destroyed or be unlocked, and in a single day its lock core is unlocked, and its dead bolt will be unlocked, and easily causes the stolen of vehicle.

Three, summary of the invention

The novel purpose of this use is to overcome the deficiencies in the prior art, a kind of good anti-theft effect is provided, has the combination motor vehicle theftproof lock of double anti-theft device.

The novel purpose of this use can realize by following technical scheme:

The combination motor vehicle theftproof lock is made up of key, lock body, lock core and the arc driving lever of being stirred by lock core, dead bolt plectrum, dead bolt.The rear portion of the dead bolt plectrum that links to each other with dead bolt is provided with arc driving lever revolution groove, the arch bar of arc driving lever is positioned at arc driving lever revolution groove, left end at the dead bolt plectrum that horizontally slips with dead bolt of lock body inner chamber has spring fitting device, the return spring of dead bolt plectrum is housed on spring fitting device, one end of return spring peaks on the spring fitting device, the other end of return spring peaks on the lock body inner chamber, dead bolt is provided with the locking groove, on the lock body of locking groove, electromagnetic switch is installed, the mounting hole of telescopic lock pin is arranged on the lock body at the telescopic lock pin place of electromagnetic switch, and the telescopic lock pin on the electromagnetic switch is corresponding with the locking groove by mounting hole.

The novel purpose of this use can also realize by following technical scheme:

Return spring is spiral spring, longitudinal center's line parallel of the longitudinal centre line of spring and dead bolt, and the left end of return spring peaks on the spring fitting device, and the right-hand member of return spring peaks on the sidewall of lock body inner chamber.

This use is novel compared with prior art to have is to have destroyed lock core also can't to open by lock, have only the electromagnetic switch of startup to make its telescopic lock pin withdrawal could open lock, has realized the advantage of double anti-theft.

Fig. 2 is the upward view (partial cutaway is shown) of combination motor vehicle anti-theft lock structure schematic diagram

Fig. 3 is the operating principle schematic diagram of combination motor vehicle theftproof lock

Fig. 4 is the local scheme of installation of combination motor vehicle theftproof lock (lock core, arc driving lever, dead bolt plectrum, dead bolt etc.)

Five, the specific embodiment

Shown in Fig. 1-4:

The combination motor vehicle theftproof lock, by key 1, lock body 2, lock core 3, and the arc driving lever of stirring by lock core 34, dead bolt plectrum 5, dead bolt 8 is formed, the rear portion of the dead bolt plectrum 5 that it links to each other with dead bolt 8 is provided with arc driving lever revolution groove 6, the arch bar of arc driving lever 4 is positioned at arc driving lever revolution groove 6, left end at the dead bolt plectrum 5 that horizontally slips with dead bolt 8 of lock body 2 inner chambers has spring fitting device, the return spring 7 of dead bolt plectrum 5 is housed on spring fitting device, one end of return spring 7 peaks on the spring fitting device, the other end of return spring 7 peaks on lock body 2 inner chambers, dead bolt 8 is provided with locking groove 9, on the lock body 2 at locking groove 9 places, electromagnetic switch 10 is installed, the mounting hole of telescopic lock pin is arranged on the lock body 2 at the telescopic lock pin place of electromagnetic switch 10, and the telescopic lock pin on the electromagnetic switch 10 is corresponding with locking groove 9 by mounting hole.Return spring 7 is spiral spring, longitudinal center's line parallel of the longitudinal centre line of spring and dead bolt 8, and the left end of return spring 7 peaks on the spring fitting device, and the right-hand member of return spring 7 peaks on the sidewall of lock body 2 inner chambers.

Its operating principle is: the arc driving lever 4 of stir down at key 1 that lock core 3 rotates, being stirred by lock core 3 is stirred dead bolt plectrum 5 and is moved right, and dead bolt plectrum 5 moves right and makes dead bolt 8 stretch out the purpose that reaches locking.The telescopic lock pin of electromagnetic switch 10 snaps in the locking groove 9 by the mounting hole of the telescopic lock pin on the lock body 2 at this moment, key 1 is stirred down lock core 3 again and is rotated, the arc driving lever of being stirred by lock core 34 can arbitrarily rotate, but it is moving (because the bottom of dead bolt plectrum 5 is the concave shapes that arrive of opening to travelling backwards to stir dead bolt plectrum 5 and dead bolt 8, arc driving lever 4 can only be locked, can not stir dead bolt plectrum 5 and dead bolt 8 and will lock unlatching to travelling backwards is moving), do not make its telescopic lock pin withdrawal if do not start electromagnetic switch 10, dead bolt 8 can not be withdrawn, be to have destroyed lock core also lock to be opened like this, have only the electromagnetic switch 10 of startup to make its telescopic lock pin withdrawal could open lock, reach the purpose that sample has reached double anti-theft.
