Abstract

The utility model provides a multi-point locking edge pin tumbler lock core, comprising a lock body, a lock core with a pin tumbler bore, a pin tumbler, a pin tumbler return spring and a locking mechanism. The locking mechanism is provided with a lock position slot at the inner side of the lock body circular hole, a stop pin slot is arranged on the lock core, and the inner side of the stop pin slot is communicated with the side surface of the pin tumbler bore and is roughly vertical to the pin tumbler bore. The outside of the edge post slot can be corresponding to the lock position slot at the inner side of the lock circular hole, each pin tumbler is provided with a slot, and the stop pin slot is provided with a stop pin. The shapes of the stop pin and the adjacent adhere end of a flute on the pin tumbler are matched with the flute on the pin tumbler, and the shapes of the stop pin and the adjacent adhere end of the lock position slot on the lock body are matched with the lock position slot. A spring which can make the stop pin slide to the inner side of the lock circular hole is arranged between the stop pin and the lock core, and the stop pin slot is a step column flute. The shapes of the stop pin and the adjacent adhere end of the lock position slot are arc surfaces, and the lock position slot on the lock body is an arc slot. Thieves can feel nothing when switching the pin tumblers, so the antitheft character is increased.

Description

The multi-point lock deckle is opened lock cylinder

Technical field:

The utility model relates to a kind of lockset, relates in particular to a kind of cylinder of spring lock.

Background technology:

At present, for the theftproof performance that improves cylinder of spring lock and the fastness of locking, the common spring lock core is carried out various improvement, as application number is 99115581.5, notification number is CN1117911C, denomination of invention is the patent of invention of " a kind of anti-theft cylinder lock and key ", the cylinder of spring lock of this patent comprises lock body, lock core, pellet shot from a slingshot, the pellet shot from a slingshot return spring, lock body circular hole inboard has the square groove, have the locking cotter way on the lock core, the pellet shot from a slingshot hole, the locking cotter way is inboard to communicate with the side in pellet shot from a slingshot hole, and with pellet shot from a slingshot hole approximate vertical, the locking cotter way outside can be corresponding with the lock-bit groove of lock body circular hole inboard, one circle V-type groove is all arranged on each pellet shot from a slingshot, be provided with stop pin in the locking cotter way, the inboard of stop pin is a V-type, can match with the V-type groove on the pellet shot from a slingshot, the outside of stop pin is a square, can match with the square groove of lock body circular hole inboard, stop pin is provided with step, with be fixed with pressing plate on the corresponding locking cotter way of the step outside, between the step of pressing plate and stop pin, be provided with the stop pin return spring, the edge that lockhole on the lock core is positioned at lock core is semiclosed shape, and the hole flank of tooth is vertical with the pellet shot from a slingshot group, this invention is because the locking device that has adopted stop pin to rotate as the control lock core, unlocking tool with non-matching key can't make each pellet shot from a slingshot locate simultaneously, and the V-type groove on it is all overlapped, so can not open lock, thereby it is better than the theftproof performance of common spring lock, but the back-moving spring of its stop pin makes stop pin press to pellet shot from a slingshot, make stop pin all the time with the pellet shot from a slingshot Elastic Contact, find sensation when stealer is unblanked with detection means, reduced the theftproof of this lock core.

Summary of the invention:

The purpose of this utility model is that the limit that proposes a kind of theftproof performance and better reliability at the deficiencies in the prior art opens lock cylinder.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the multi-point lock deckle is opened lock cylinder, comprise lock body, have the lock core in pellet shot from a slingshot hole, pellet shot from a slingshot, pellet shot from a slingshot return spring and locking mechanism, described locking mechanism is to have the lock-bit groove in lock body circular hole inboard, have the locking cotter way on the lock core, the locking cotter way is inboard to communicate with the side in pellet shot from a slingshot hole, and with pellet shot from a slingshot hole approximate vertical, the locking cotter way outside can be corresponding with the lock-bit groove of lock body circular hole inboard, all fluted on each pellet shot from a slingshot, be provided with stop pin in the locking cotter way, the shape of the groove close neighbour end on stop pin and the pellet shot from a slingshot and the groove on the pellet shot from a slingshot are complementary, the shape and the lock-bit groove of the lock-bit groove close neighbour end on stop pin and the lock body are complementary, between described stop pin and lock core, be provided with and make stop pin slide to the spring of lock body circular hole inboard, described stop pin is provided with several, the locking cotter way is the step cylindrical groove, stop pin and lock-bit groove close neighbour end be shaped as arcwall face, lock-bit groove on the lock body is a deep-slotted chip breaker, during rotational lock core, stop pin and lock-bit groove can slide and snap in the groove on the pellet shot from a slingshot relatively.

Both sides at pellet shot from a slingshot are equipped with locking mechanism.

Groove on the described pellet shot from a slingshot is a deep-slotted chip breaker, and an antitheft groove also is set on the described pellet shot from a slingshot at least.

One end of described pellet shot from a slingshot close neighbour pellet shot from a slingshot return spring is provided with the spring resettlement groove.

The beneficial effects of the utility model are: at first, because the stop pin in the locking mechanism is under the effect of spring, all the time slide to lock body circular hole inboard, during locking states, can leave certain clearance between stop pin and the pellet shot from a slingshot, make stealer when stirring pellet shot from a slingshot, can not find any sensation, increased the theftproof of this lock greatly with regard to this, a plurality of stop pins and lock-bit groove adopt cambered surface to cooperate with cambered surface, are the reliability of face when contacting this and just having increased locking.Secondly, be provided with locking mechanism, make its better reliability in the pellet shot from a slingshot both sides.The 3rd, groove on the pellet shot from a slingshot adopts deep-slotted chip breaker, can overcome straight groove of prior art and V-type groove because stress is concentrated the shortcoming that causes the pellet shot from a slingshot insufficient strength, and pellet shot from a slingshot is provided with antitheft groove, makes that stealer is more difficult to find unlock position groove real on the pellet shot from a slingshot.The 4th, an end of pellet shot from a slingshot is provided with the spring resettlement groove makes pellet shot from a slingshot return spring when work more reliable.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
