Abstract
The present invention provides a double locking side ball lock core which comprises a lock body, a lock core, balls and ball return springs, wherein a locking position groove is arranged on the inner side of a circular hole of the lock body, the lock core is provided with a side column groove and a ball hole, the inner side of the side column groove is communicated with the side surface of the ball hole and is approximately perpendicular to the ball hole, the outer side of the side column groove is corresponding to the locking position groove on the inner side of the circular hole of the lock body, each ball is provided with a groove, a locking side column is arranged in the side column groove, a spring which can make the locking side column slide to the inner side of the circular hole of the lock body is arranged between the locking side column and the lock core, the shape of the adjacent end of the locking side column and the locking position groove is a cambered slope, the locking position groove in the lock body is a slope groove, and when a rotating lock core is formed, the locking side column forms a relative slip with the locking position groove and is clamped in locking mechanisms of grooves in the balls. When the balls are poked by a thief, the thief can not find any feeling, the theft protection property of the lock is greatly enhanced, and in addition, the locking side column and the locking position groove adopt the fitting between a cambered slope and a slope, and the surface contact enhances the reliability of the locking.
Description
Technical field:
The present invention relates to a kind of lockset, relate 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 side column groove on the lock core, the pellet shot from a slingshot hole, the side column groove 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 side column groove 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 locking side column in the side column groove, the inboard of locking side column is a V-type, can match with the V-type groove on the pellet shot from a slingshot, the outside of locking side column is a square, can match with the square groove of lock body circular hole inboard, locking side column is provided with step, with be fixed with pressing plate on the corresponding side column groove of the step outside, between the step of pressing plate and locking side column, be provided with the locking side column 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 locking side column 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 locking side column makes locking side column press to pellet shot from a slingshot, make locking side column 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:
Lock cylinder is opened on the limit that the objective of the invention is to propose at the deficiencies in the prior art a kind of theftproof performance and better reliability.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the twin-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 side column groove on the lock core, the side column groove 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 side column groove 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 locking side column in the side column groove, the shape of the groove close neighbour end on locking side column 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 locking side column and the lock body are complementary, between described locking side column and lock core, be provided with and make locking side column slide to the spring of lock body circular hole inboard, the cross section of described locking side column is the mountain font, the side column groove is the step groove, locking side column and lock-bit groove close neighbour end be shaped as curve slope, lock-bit groove on the lock body is a surface groove, during rotational lock core, locking side column 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.
Described spring is a zigzag, places between the step surface of the grooves on two sides of mountain font locking side column and side column groove.
Groove on the described pellet shot from a slingshot is the U type, 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.
Beneficial effect of the present invention is: at first, because the locking side column 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 locking side column 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, locking side column and lock-bit groove adopt the arc inclined-plane to cooperate with the inclined-plane, 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 arc and the tangent U type groove of straight line, can overcome straight groove of prior art and V-type groove because stress is concentrated the shortcoming cause the pellet shot from a slingshot insufficient strength, and pellet shot from a slingshot is provided with antitheft groove, make that stealer is more difficult to find unlock position groove real on the pellet shot from a slingshot.The 4th, spring adopts the zigzag spring, can increase the steadiness that spring is installed.The 5th, 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 invention will be further described below in conjunction with embodiment and accompanying drawing.
