Description

A kind of mechanical anti-theft puzzle lock

The utility model relates to lock technology field, particularly a kind of mechanical anti-theft puzzle lock.

The utility model patent application a few days ago, lockset open, that sell, use mainly contains safe-guard door lock and mechanical code lock.Safe-guard door lock is mostly directly controlled the flexible of dead bolt, and lock is nearer with doorframe, and latched position is obvious.Mechanical code lock has turning handle on its figure disc, can optionally rotate figure disc.All there is certain defective in the safe precaution measure of these two kinds of locksets.

Goal of the invention of the present utility model is that a kind of simple in structure, safe and reliable novel mechanical anti-theft puzzle lock will be provided.

Foregoing invention purpose of the present utility model realizes by following technical proposals:

A kind of mechanical anti-theft puzzle lock, comprise: theftproof lock, mechanical code lock, several parts of drive lock fixed system are formed, it is characterized in that described theftproof lock is fixed on the door, the figure disc of mechanical code lock is installed on the theftproof lock, and the lock core of theftproof lock directly links to each other with the universal driving shaft of mechanical code lock and is on the same axis.

The figure disc of described mechanical code lock is installed on the theftproof lock, the lock core of theftproof lock directly links to each other with the universal driving shaft of mechanical code lock and is on the same axis, purpose is theftproof lock and mechanical code lock are combined into one, and realizes safe and reliable purpose of design.Open password with the key turns of theftproof lock, do not have the key just can't transcoding.Theftproof lock inserts its corresponding key, because the axle of the axle of the lock core of theftproof lock and transcoding wheel link, in the time of rotation theftproof lock key, transcoding is taken turns and just can be rotated thereupon.Owing to be fixed with figure disc on the door, theftproof lock number on the key rotates sign corresponding on the figure disc during certain number, and it allows the breach on certain inner transcoding wheel just aim at the catch in the door handle blocking lock fixed system.When coming back rotation theftproof lock key to some position, the breach on all transcoding wheel is all alignd with catch in the door handle blocking lock fixed system, at this moment turn the handle and can open the door.

In order to increase the reliability of mechanical anti-theft puzzle lock, can be set to 2～5 by the deflecting roller number, its concrete number can be set up.The user not only can set up password, can also set up the deflecting roller number, i.e. the figure place of password.

Described door handle blocking lock fixed system links to each other with the stop pin of the upper and lower, left and right four direction of door, and upper and lower, left and right four direction that can lock door makes anti-collision, the pick-proof ability of door stronger.

The mechanical anti-theft puzzle lock of the utility model structure has advantages such as simple in structure, safe and reliable.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Embodiment 1:

A kind of mechanical anti-theft puzzle lock, comprise: theftproof lock, mechanical code lock, drive lock fixed system, theftproof lock 2 is fixed on the door, and the figure disc 3 of mechanical code lock is installed on the theftproof lock 2, and the lock core 1 of theftproof lock 2 directly links to each other with the universal driving shaft 5 of mechanical code lock and is on the same axis.Door handle blocking lock fixed system 6 is connected with the stop pin 7 of the upper and lower, left and right four direction of door, and door handle 8 is connected with door handle blocking lock fixed system 6.It is 5 that transcoding is taken turns 4 numbers.
