Abstract
The invention provides a mechanical lock, comprising a lock case, a lock cylinder, a spring and a lock billiard, wherein the lock cylinder is provided with two billiard holes that are partially communicated with each other; the communicated section is provided with an irregular billiard and a punchy spring; one billiard hole is communicated with a billiard hole, and the other billiard hole is provided with a billiard in which one end is ladder-shaped and is connected with a key hole; the irregular billiard abuts against the lock billiard and the billiard; the billiard hole of the lock case and the lock billiard contacting with the spring are higher than the lock cylinder; one side of the billiard body is provided with a real groove and a false groove, and the other side of the billiard body is provided with billiard teeth which can move at the communicated section of the billiard holes; the lock case and the lock cylinder are provided with corresponding rectangular grooves, and are communicated with the billiard holes with the billiard; the rectangular groove is internally provided with a movable lock plunger; and one side of the rectangular groove is in a shape of circular arc, and the other side of the rectangular groove is provided with lock plunger teeth which can coordinate with the true groove of the billiard, wherein the lock plunger is not higher than the lock cylinder when the lock plunger teeth coordinates with the true groove of the billiard. The mechanical lock provided by the invention has the beneficial effect that the mechanical lock is opened technically so that the lock plunger and the lock billiard are easy to block the lock case and the lock cylinder, thus the mechanical lock can be preferably prevented from opening technically.
Description
Technical field
The present invention relates to a kind of lockset, particularly relate to mechanical lock.
Background technology
The present mechanical lock that uses, be that lock core and lock housing are provided with a plurality of corresponding pellets shot from a slingshot hole, be provided with the lock pellet shot from a slingshot of spring and two group in each pellet shot from a slingshot hole, spring in the lock housing pellet shot from a slingshot hole compresses the lock pellet shot from a slingshot, block lock housing and lock core with the lock pellet shot from a slingshot that spring touches mutually, lock core can not be rotated in lock housing, and at this moment, mechanical lock is in locking states.When inserting keyhole with supporting key, teeth on the key compress corresponding with it lock pellet shot from a slingshot on the direction of lock housing pellet shot from a slingshot hole and move, when the arc surface of two lock contact surfaces of pellets shot from a slingshot and lock housing and lock core is crossing, the lock pellet shot from a slingshot can not stop lock core to rotate in lock housing, at this moment, mechanical lock is in opening.And technical unlocking adopts non-supporting unlocking tool, by the dynamics to a rotation of lock core, and then stirs the lock pellet shot from a slingshot and moves on the direction of lock housing pellet shot from a slingshot hole, is easy to make the lock pellet shot from a slingshot to move to the lock opening, thereby opens mechanical lock.Because of existing appeal not enough, the performance of the anti-technical opening of this mechanical lock is bad.
Summary of the invention
In order to overcome the deficiency that the existing mechanical lock can not prevent technical unlocking, provide a kind of mechanical lock that can prevent technical unlocking.
The technical solution adopted for the present invention to solve the technical problems is: it comprises lock housing, lock core, spring, the lock pellet shot from a slingshot, two partially communicating shell holes are set on lock core, be provided with a special-shaped pellet shot from a slingshot and a brute spring of forming by two continuous pellets shot from a slingshot at the shell hole connected component, brute spring compresses special-shaped pellet shot from a slingshot, these two partially communicating shell hole one ends are set, be communicated with a pellet shot from a slingshot hole on the lock core, in the lock core marble hole that communicates, the abnormity pellet shot from a slingshot compresses mutually with the lock pellet shot from a slingshot, is higher than lock core with lock pellet shot from a slingshot that spring touches mutually under the effect of special-shaped pellet shot from a slingshot in the corresponding lock housing pellet shot from a slingshot hole.Keyhole is set links to each other, and be provided with pellet shot from a slingshot with the partially communicating shell hole other end.End at the pellet shot from a slingshot of keyhole is a trapezoidal shape, pellet shot from a slingshot body one side is provided with the pellet shot from a slingshot teeth, the pellet shot from a slingshot teeth can be done the rotation of limited radian at the connected component of two partially communicating shell holes, are provided with true groove and false groove at the opposite side of pellet shot from a slingshot body, and special-shaped pellet shot from a slingshot compresses pellet shot from a slingshot.Lock housing is provided with corresponding rectangular channel with lock core, the shell hole that is connected with lock core keyhole is communicated with, be provided with mobilizable locking bolt in the rectangular channel, locking bolt is circular shape to a side of lock housing, locking bolt has the locking bolt teeth to a side of shell hole, be provided with the locking bolt spring between the locking bolt teeth, the locking bolt spring compresses lock core makes locking bolt exceed lock core.The locking bolt teeth can cooperate fully with the true groove of pellet shot from a slingshot, and locking bolt is not higher than lock core.The locking bolt teeth cooperate not exclusively with the false groove of pellet shot from a slingshot, and locking bolt exceeds lock core.
The invention has the beneficial effects as follows, with non-supporting unlocking tool, the true groove energy and the locking bolt teeth of the pellet shot from a slingshot in the shell hole are all cooperated, otherwise locking bolt exceeds lock core, hinders lock core and rotates in lock housing during technical unlocking.And by to rotation dynamics of lock core, when stirring the lock pellet shot from a slingshot in the keyhole, the lock pellet shot from a slingshot in pellet shot from a slingshot hole that sticks lock housing and lock core is unaffected, the mechanical lock state that still keeps Locked.Therefore, this mechanical lock has well anti-technical opening performance.
