Detailed Description

Example (b): the utility model provides a technical opening prevention trick lock, includes lock shell 1, outer password wheel 2, interior password wheel 3 and catch 4, catch 4 can form confined loop configuration with

lock shell

1, and 3 circumferencial direction of a plurality of interior password wheels can the pivoted locate in lock shell 1, and the 3 outsides of each interior password wheel are located to the cover of 2 one-to-ones of a plurality of outer password wheels, and outer password wheel 2 can be connected with 3 circumferencial direction locking locks of interior password wheel, all is equipped with dropout structure on 3 circumference lateral walls of each interior password wheel, the dropout structure on 3 circumference lateral walls of each interior password wheel all reaches after the assigned position can make catch 4 and lock shell 1 dropout, its characterized in that: the anti-theft code wheels 5 are sleeved on the outer sides of the circumferences of the outer code wheels 2 in a one-to-one correspondence mode, and the anti-theft code wheels 5 are connected with the outer code wheels 2 in a locking mode in the circumferential direction in a locking mode. An anti-theft password wheel 5 is sleeved outside the outer password, when the lock is unlocked, the lock ring 4 is held by a hand, the anti-theft password is rotated while the lock ring 4 is pulled, at the moment, the hand does not directly contact the outer password wheel 2, the clamping stagnation feeling of the outer password wheel 2 and the inner password wheel 3 cannot be felt, and therefore the technical opening cannot be realized.

And a password mark 6 is arranged on the surface of the anti-theft password wheel 5. Or a transparent part is formed on the anti-theft code wheel 5, and the codes on the outer code wheel 2 are displayed through the transparent part.

The anti-theft password wheel 5 and the outer password wheel 2 are mutually inserted through the radial concave-convex structure 7 to realize buckling connection. Concave-convex structure 7 sets up the recess if on outer password wheel 2, set up the arch at the 5 inboard of theftproof password wheel, or set up the arch on outer password wheel 2, set up the recess at the 5 inboard of theftproof password wheel, still or set up corresponding building and keyway structure outside password wheel 2 outside and the 5 inboard of theftproof password wheel, still or set up the just jack in position on outer password wheel 2 and theftproof password wheel 5, wear to locate in the jack of the two through the pin and so on, realize that outer password wheel 2 is connected with 5 locks of theftproof password wheel, both realized that theftproof password wheel 5 drives outer password wheel 2 and rotate in step, make the clearance exist between the two again.

The outer password wheel 2 is hidden in a space formed by the anti-theft password wheel 5 and the lock shell 1. Avoiding a person from being able to contact the outer code wheel 2 when unlocking.
