Abstract

The utility model relates to a mechanical pin tumbler lock comprising a lock core, pin tumblers, a pin tumbler spring, wherein the pin tumblers have recesses, the lock core is provided with slide blocks along the axis on two sides, springs are provided between the two slide blocks, an arc chute is provided inside the lock body which is coplanar with the two slide blocks. When unlocked, a key is inserted in a key slot of the lock core, so all the recesses of the disordered pin tumblers are adjusted to one flat surface and are in alignment with the edge of the two slide blocks, then the user rotates the lock core, the cambered surface of the slide blocks is extruded by the arc chute inside the lock body to overcome the thrust of the spring and to enter in the recesses, so the lock core is capable of rotating in the lock body. When the key is pulled, the pin tumblers restore original position under the action of the two springs between the pin tumbler spring and two slide blocks, the slide blocks is pushed into the arc chute of the lock body, thereby the lock is in the state of locking. Because the pin tumblers are two rows, many quantities and large recesses, the difficulty of the open technologically is increased and the safety improved greatly. The two slide blocks provided between the lock core and the lock body is capable of preventing effectively forced turning, to further improve the safety. The utility model can be widely used for locks with various types and various applications.

Description

A kind of mechanical spring lock head

Technical field

The utility model relates to field of lockset, especially mechanical spring lock head.

Background technology

At present, known mechanical lock tapered end generally is made of lock body, lock gall, pellet shot from a slingshot, pellet shot from a slingshot spring.The pellet shot from a slingshot spring has two pellets shot from a slingshot in the shell hole in lock body.During lock-out state, a pellet shot from a slingshot is in lock gall, and a pellet shot from a slingshot is between lock gall and lock body.During unlocking condition, a pellet shot from a slingshot is in lock gall, and a pellet shot from a slingshot because the tartar amount is few, mutual opening rate is high, has by the defective of technical unlocking, can not prevent to turn round poor stability by force in lock body.

Summary of the invention

In order to overcome the deficiency of existing machinery ball lock head, the utility model provides a kind of anti-technical unlocking, the anti-mechanical spring lock head of turning round by force.

The technical scheme that its technical problem that solves the utility model adopts is: lock gall, pellet shot from a slingshot, pellet shot from a slingshot spring are arranged in the lock body, notch is arranged on the pellet shot from a slingshot, lock gall has slide block along the axis both sides, and there is spring on both sides between two slide blocks, with the lock body inboard of two slide block coplanes deep-slotted chip breaker is arranged.When unblanking, key inserts the lock gall key, and the pellet shot from a slingshot notch that all are unordered is adjusted to same plane, and align with the limit of two slide blocks, rotate lock gall this moment, the cambered surface of slide block is subjected to that the thorax deep-slotted chip breaker pushes in the lock body, overcome the thrust of spring, enter into the pellet shot from a slingshot notch, lock gall can rotate in lock body.After extracting key, pellet shot from a slingshot, sets back under two spring actions betwixt of two slide blocks at the pellet shot from a slingshot spring, and slide block is pushed in the deep-slotted chip breaker of lock body, and tapered end is in locking states.

The beneficial effects of the utility model are: because pellet shot from a slingshot is two row, a plurality of, the tartar amount is big, and difficulty of technical opening greatly increases, and safety greatly improves.Double-slider places between lock gall and the lock body, can effectively prevent to turn on by force, has further improved security performance.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the organigram in the vertical section of the utility model embodiment, and slice location is the II-II of Fig. 2.

Fig. 2 is the I-I sectional view of Fig. 1.

Among Fig. 1 and Fig. 2,1. lock body, 2. lock gall, 3. pellet shot from a slingshot, 4. pellet shot from a slingshot spring, 5. notch, 6. slide block, 7. spring, 8. deep-slotted chip breaker, 9. bearing pin, 10. straight flange, 11. jump rings, 12. key, 13. anti-drilling sheets, 14. shoulders.

The specific embodiment

In Fig. 1 and Fig. 2, lock gall (2) is connected with lock body (1) with jump ring (11) by shoulder (14), realizes axial restraint.Pellet shot from a slingshot (3) is two row, a plurality of along axially symmetrical distribution of lock gall (2), has the corresponding joint portion of straight flange (10) and lock gall (2) that pellet shot from a slingshot (3) can only be moved axially on pellet shot from a slingshot (3) cylindrical cross section, and can not rotate.Also available pellet shot from a slingshot (3) face of cylinder is along axis guide groove or projection and projection on the corresponding lock gall (2) or gathering sill location with it, in case pellet shot from a slingshot rotates.Each pellet shot from a slingshot of axial location (3) of notch (5) on the pellet shot from a slingshot (3) is all inequality.Two slide blocks (6) are compressed near the deep-slotted chip breaker (8) in the lock body (1) by bearing pin (9) by two springs (7) therebetween, at this moment tapered end place locking states.Have only when key makes notch (5) on all unordered pellets shot from a slingshot (3) be in same plane and align with slide block (6) one side, notch (5) on slide block (6) and pellet shot from a slingshot (3) cylinder contacted one side thickness and the pellet shot from a slingshot (3) matches, rotate lock gall (2) this moment again, slide block (6) is pushed and makes spring (7) to shrink by lock body (1) arc groove (8), one side of slide block (6) is slipped in the notch (5) of two row pellets shot from a slingshot (3), and lock is unlocked.Anti-drilling sheet (13) is opened to prevent to be bored by force.

Claims
