Abstract

The utility model relates to a labyrinth anti-theft lock which consists of an external lock and an internal lock. The external lock is provided with a plurality of lockholes. At least two of the lock holes are provided with true lock cores. The tail of the true lock hole is connected with a gear. A rack latch is arranged in the internal lock in correspondence with the true lock core of the external lock. A tail linkage of the true lock core of the external lock inserts into the internal lock. A gear at the end of the tail linkage is meshed with the rack of the rack latch in the internal lock. The latch poles of at least two rack latches are directly linked or are linked through linkages so that the rack latches can only be opened in sequence. The lock of the utility model is provided with a plurality of key holes, a portion of which are false. In addition, an in-laid touch-off switch is arranged in the false key hole. On one hand, the false key holes can puzzle the theft. On the other hand, an annunciator arranged in the lock is turned on when the theft put the key in a false key hole. The lock can be opened only when the key inserts into the true key holes in the correct sequence. The utility model is of compact and handy structure, which is like a labyrinth to an outsider. Therefore, the utility model is of good anti-theft performance and ideal anti-theft effectiveness.

Description

The labyrinth theftproof lock

Technical field

The utility model relates to a kind of theftproof lock.

Background technology

At present, used theftproof lock such as house and motor vehicle is various in style, but anti-theft effect is all not very good, and its theftproof performance is still waiting further raising.

Summary of the invention

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of theftproof performance good, the labyrinth theftproof lock that anti-theft effect is very good.

Technical solution of the present utility model:

A kind of labyrinth theftproof lock, it is characterized in that it is made up of outer lock body and interior lock body one, outer lock body is provided with a plurality of lockholes, have two in each lockhole at least true lock core is set, this true lock core tail end link end is connected with gear, correspondingly in interior lock body corresponding outside the true lock core of lock body position be provided with the tooth bar dead bolt, the true lock core tail end of outer lock body connecting rod penetrates interior lock body, the tooth bar engagement of the corresponding tooth bar dead bolt in the gear of its termination and the interior lock body, and the dead bolt bar of at least two tooth bar dead bolt or directly mutually interlock or by the connecting rod interlock make them to open in proper order.

Lock body of the present utility model is provided with a plurality of key eyes, wherein part key eye is false, and false key intraocular is provided with built-in trigger switch, it is on the one hand in order to the fascination burglar, when burglar's wrong plug key the time, connect alarm equipment alarm on the other hand, be provided with two or more dead bolts in the lock body of the present utility model, their interlaced connections, have only key to insert true key successively at the moment, lock could be opened by proper order.The utility model compact conformation, ingenious, the labyrinth is the same can't open just like entering for the stranger, so have good theftproof performance, anti-theft effect is very good.

Fig. 2 is the decomposition texture schematic diagram of the circular lock of the utility model;

Fig. 3 is the decomposition texture schematic diagram of the utility model Bar lock.

The specific embodiment

As Fig. 1-3, the utility model is made up of outer lock body 1 and interior lock body 2 one, outer lock body 1 is provided with a plurality of lockholes 3, have at least two true lock core is set in each lockhole 3, these true lock core tail end connecting rod 4 terminations are connected with gear 5, correspondingly in interior lock body 2 corresponding outside lock body 1 true lock core position be provided with tooth bar dead bolt 6, outer lock body 1 true lock core tail end connecting rod 4 penetrates interior lock body 2, the tooth bar engagement of the corresponding tooth bar dead bolt 6 in the gear 5 of its termination and the interior lock body 2, and the dead bolt bar of at least two tooth bar dead bolt 6 or directly mutually interlock or by the connecting rod interlock make them to open in proper order.

In the utility model, the shape size of outer lock body 1 and interior lock body 2 is identical, and they can be square, and is also circular, goes back bar shaped or other shape.

Structure such as Fig. 1,2 that two tooth bar dead bolts 6 of the present utility model directly link mutually, the dead bolt bar of its two tooth bars dead bolt 6 is orthogonally set, and the dead bolt bar rear portion of wherein horizontally disposed tooth bar dead bolt 6 is connected with and protrudes out piece 7, under the lock body open mode, correct the dead bolt bar rear portion that is stuck in horizontally disposed tooth bar dead bolt 6 in the dead bolt bar of vertically disposed tooth bar dead bolt 6 and protrude out on the piece 7.When lock body of the present utility model uses, can only earlier outside back-out of the dead bolt bar of vertically disposed tooth bar dead bolt 6 be entered in the corresponding dead bolt hole that is arranged on the locked object by the corresponding true lock core of outer lock body 1, the dead bolt bar the inner that makes vertically disposed tooth bar dead bolt 6 protrudes out piece 7 from the dead bolt bar rear portion of horizontally disposed tooth bar dead bolt 6 throws off, and another corresponding true lock core that then could be by outer lock body 1 outwards screws out the dead bolt bar of horizontally disposed tooth bar dead bolt 6 and enters in another the corresponding dead bolt hole that is arranged on the locked object.Otherwise, if the tooth bar dead bolt 6 that first level of movement is provided with just can't completely shut operation.Equally, when unblanking, can only open horizontally disposed tooth bar dead bolt 6 earlier, and then open vertically disposed tooth bar dead bolt 6, lock could be opened like this, otherwise, if opened vertically disposed tooth bar dead bolt 6 earlier,, the dead bolt bar of horizontally disposed tooth bar dead bolt 6 puts in place in any case being opened.

The utility model two tooth bar dead bolts 6 are by structure such as Fig. 3 of connecting rod interlock, upper and lower the be arrangeding in parallel of dead bolt bar of its two tooth bars dead bolt 6, position between the corresponding upper and lower tooth bar dead bolt 6 is provided with elasticity positioning linkage rod 8 on interior lock body 2, be respectively equipped with upper protruding block 9 and lower protruding block 10 on the dead bolt bar opposite face of upper and lower tooth bar dead bolt 6, the upper protruding block 9 of upper rack dead bolt 6 is the inclined-plane projection, positioning linkage rod 8 upper ends are usually above the position of inclined-plane upper protruding block 9, and its lower end is concordant with lower protruding block 10 summits of following tooth bar dead bolt 6.

When unblanking, tooth bar dead bolt 6 is regained, made down the lower protruding block 10 of the dead bolt bar of tooth bar dead bolt 6 be positioned at the rear portion of positioning linkage rod 8 lower ends, regain upper rack dead bolt 6 then, make its upper protruding block 9 bottoms just in time push down positioning linkage rod 8 upper ends, make positioning linkage rod 8 lower ends push down down tooth bar dead bolt 6 again.During locking, can not screw out down earlier tooth bar dead bolt 6, can only screw out upper rack dead bolt 6 earlier, elasticity positioning linkage rod 8 is resetted, could screw out down tooth bar dead bolt 6 then.

If the number of true lock core of the present utility model is more, then the link gear of corresponding each tooth bar dead bolt 6 is more exquisite, and anti-theft effect is better.Also be provided with a plurality of false lockholes 3 on the outer lock body 1 of the present utility model in addition, and be provided with false locking bar in the false lockhole 3 that has, can confuse the burglar, be provided with built-in trigger switch in the false lockhole 3 that has, when burglar's wrong plug key, connect alarm equipment alarm like this, make anti-theft effect more perfect.
