Abstract

The utility model relates to a trap type anti-theft lock with a mechanical cylinder structure, which is characterized in that the lock (3) is provided with two corresponding holes arranged at the position having a definite angle with a first ball hole of a lock core; locking cylinders (4) is arranged in the holes; each hole is provided with a hole corresponding to and communicated with the hole at the vertical orientation; a lock pin (5), a lock pin spring (6) and a screw (7) are arranged in the hole. By the utility model, when others use other foreign matters or methods to unlock the lock, even the function of the cylinder is destroyed and the lock core is rotated, whether the lock core is leftwards rotated or rightwards rotated, the lock is locked again and can not be unlocked.

Description

Trap type mechanical billiard structure anti-theft lock end

The utility model relates to the safe-guard door lock at household gate, particularly the safe-guard door lock of mechanical billiard formula.

At present commercially available mechanical billiard formula safe-guard door lock style is many, some difference between structure is also mutual.Each lockmaking merchant is in order to improve the theftproof performance of safe-guard door lock, and at size of key that improves constantly lockset and theft preventing method such as anti-drilling, this has played certain positive role for social security, home security undoubtedly to a certain extent.But the safe-guard door lock that comes to this also is difficult to prevent technical unlocking, and the criminal is as long as rotated lock core just and lock can have been opened.

The purpose of this utility model provides a kind of trap type mechanical billiard structure anti-theft lock end, when adopting other foreign matter or method, other people open tapered end, although the effect of pellet shot from a slingshot is cracked and make lock core obtain rotation, no matter be left-handed or dextrorotation, lock just locks for the second time and can't open.

Technical solution of the present utility model is on the basis of existing machinery pin tumbler lock, the utility model is provided with locational two respective aperture angled with first hole of bead of lock core on tapered end, the locking pellet shot from a slingshot is housed in the hole, the one corresponding hole that communicates is with it arranged on the vertical orientations in this hole, lock pin is housed, lock pin spring and screw in the hole.

The above tapered end is provided with locational two respective aperture angled with first hole of bead of lock core, and its certain angle is 30 degree, or 45 degree, 90 are spent.

Operating principle of the present utility model is that when using match key operated, the locking pellet shot from a slingshot in the tapered end can not fall into the hole of lock core.Therefore lock is unlocked.When opening with foreign matter or other method, when opening with electromagnetic shaker, lock core has rotated, and the locking pellet shot from a slingshot is subjected under the active force of lock pin and lock pin spring when forwarding 90 degree orientation to, snaps in the pellet shot from a slingshot hole on the lock core, locks lockedly, and this that is to say the 2nd locking.This locking is irreversible, and reinstalling behind the screw of only outwarding winding just can reset reuses, and this owner to lock is fully feasible, however concerning the thief resetting in any case, all because of opening with phase-locked key of joining.

The utility model has the advantages that working as other people adopts other foreign matter or method to open tapered end, although the effect of pellet shot from a slingshot is cracked and make lock core obtain rotation, no matter be left-handed or dextrorotation, lock just locks for the second time and can't open.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Fig. 1 organigram of the present utility model;

Fig. 2 B-B profile construction of the present utility model schematic diagram.

Shown in Fig. 1,2, the utility model has a tapered end 3, the rotatable lock core 2 that is fixed with in tapered end 3, and there are pellet shot from a slingshot hole and pellet shot from a slingshot in the corresponding position on lock core 2 and tapered end 3.On tapered end 3, be provided with locational two respective aperture that become 90 degree with first hole of bead of lock core, locking pellet shot from a slingshot 4 is housed in the hole, a corresponding hole that communicates is with it arranged on the vertical orientations in this hole, dress lock pin 5, lock pin spring 6 and screw 7 in the hole.
