Abstract

The utility model discloses an anti-theft lock, which comprises a lock stock [6] and a lock core positioned in a through hole of the lock stock [6], wherein the lock core and the lock stock [6] can rotate oppositely; two ends of the lock stock are provided with positioning rings [4] for positioning the lock core in an axial direction; a plurality of radial holes which are communicated are formed in the lock core and the lock stock [6]; and balls and springs which cooperate with a key for unlocking are arranged in the holes. The anti-theft lock is characterized in that the lock core is divided into two sections which are not connected, namely a front section lock core [7] and a rear section lock core [5]; and a self-lock mechanism is arranged on the front section lock core [7]. The anti-theft lock is good in anti-theft effect, so technical unlocking can be effectively prevented.

Description

A kind of theftproof lock
Technical field
The utility model relates to a kind of theftproof lock, especially a kind of twin-core theftproof lock.
Technical background
The marble mechanical lock tool of traditional structure is used very extensively, and it cooperates with pellet shot from a slingshot in the lock core through key, and lock core is rotated, and is accomplished and is unblanked and lock by the trip of stirring that is connected with lock core again, so use the convenience of ten minutes.But there is very big shortcoming in this lockset: as long as apply moment of torsion to lock core, utilize special instrument that the pellet shot from a slingshot of lock core is compressed one by one again, the cooperation experience just can realize skilled unlocking, so safety is not high.For solving the not high shortcoming of common lockset safety; People have designed various types of pellet shot from a slingshot mechanical anti-theft locks; Like publication number is the disclosed L shaped keyhole pellet shot from a slingshot machinery lock of Chinese patent document of CN1080351A; It is to utilize lockhole inner space little cooperation tip pellet shot from a slingshot not stay move place for the lock core inner chamber, makes master key or special instrument be difficult to get into lock core or gets into lock core to work, thereby reach the purpose of antitheft.The shortcoming of this type lockset is that structure is comparatively complicated, the purpose that still is difficult to fundamentally reach antitheft for the special instrument of precision simultaneously.
The utility model content
The purpose of the utility model is to provide a kind of theftproof lock of simple in structure, safe and applicable, it effectively precautionary technology property unblank, the safety of mechanical cylinder lock is improved greatly.
The technical scheme that the utility model adopts is: a kind of theftproof lock; It comprises lock embryo and the lock core that is arranged in lock embryo through hole, and lock core can relatively rotate with the lock embryo, and lock embryo two ends are provided with centring ring to the lock core axial location; Lock core has some radial holes that communicate with locking on the embryo; The pellet shot from a slingshot and the spring that cooperate unlatching with key are housed in the hole, it is characterized in that said lock core is divided into disjunct two sections, is respectively leading portion lock core and back segment lock core.
Adopt technique scheme, when skilled unlocking, the person of unblanking must apply certain torque to lock core; Make lock core and lock embryo that relative minor rotation take place; Be convenient to the pellet shot from a slingshot in the pin, because the utility model lock core is divided into disjunct two sections, so the back segment lock core that torque can not inwards transmits; Pellet shot from a slingshot in the inner segment lock core that makes can't be fixed, thereby reaches the purpose that prevents skilled unlocking effectively.
For further increasing the safety of mechanical lock; On the leading portion lock core, be provided with self-locking mechanism, described self-locking mechanism comprises push rod, self-lock pin and first back-moving spring and second back-moving spring, and the leading portion lock core has axial hole on the end face adjacent with the back segment lock core; Push rod is positioned at axial hole; The bottom of push rod is provided with first back-moving spring push rod is pushed, the back segment lock core be provided with the arc groove that cooperates with push rod with leading portion lock core adjacent face, transition and push rod form the inclined-plane and cooperate arc groove gradually to the both sides end face by the centre; First back-moving spring withstands on the push rod end in the arc groove; Have the radial hole that communicates with axial hole on the leading portion lock core, self-lock pin is located in the radial hole, connects through oblique mechanism between its lower end and the push rod; Second back-moving spring is pressed in self-lock pin on the push rod, on the lock embryo, is provided with the confession self-lock pin with the self-lock pin corresponding section and realizes the circumferential recess to the lock core self-locking.
Adopt technique scheme, when skilled unlocking, apply a torque for the leading portion lock core; Push rod rotates in the arc groove of back segment lock core end face; Because the effect of arc groove inclined-plane transmission mechanism, arc groove is compressed first back-moving spring through push rod, and push rod moves in the Kong Xiangkong vertically; Push rod through and self-lock pin between oblique mechanism promote self-lock pin and radially move and get in the circumferential recess on the lock embryo in the hole; Make this section lock core and lock embryo can not produce than the relatively rotating of wide-angle, thereby realize the self-locking of lock core and lock embryo, reach the purpose of further increase safety through self-lock pin.
In sum, the utility model beneficial effect is: because the utility model passes through the segmentation of mechanical billiard lock core, the torque that is applied on the leading portion lock core can not only make its safety improve greatly to the transmission of back segment lock core, and simple in structure; Owing on lock core, also be provided with self-locking mechanism, so safety is higher.

The specific embodiment
Embodiment: a kind of theftproof lock, as shown in Figure 1, it comprises lock embryo 6 and the lock core that is arranged in lock embryo 6 through holes; Lock core can relatively rotate with lock embryo 6; Lock embryo two ends are provided with 4 pairs of lock core axial location of centring ring, and lock core has some radial holes that communicate with locking on the embryo 6, are equipped with in the hole with key to cooperate pellet shot from a slingshot and the spring of opening; Said lock core is divided into disjunct two sections, is respectively leading portion lock core 7 and back segment lock core 5.Leading portion lock core 7 is provided with self-locking mechanism.
Self-locking mechanism such as Fig. 1, shown in Figure 2; It comprises push rod 3, self-lock pin 9 and first back-moving spring 8 and second back-moving spring 1; Leading portion lock core 7 has axial hole on the end face adjacent with back segment lock core 5, push rod 3 is positioned at axial hole, and the bottom of push rod 3 is provided with 8 pairs of push rods 3 of first back-moving spring and pushes; Back segment lock core 5 be provided with the arc groove 10 that cooperates with push rod 3 with leading portion lock core 7 adjacent faces, like Fig. 3, shown in Figure 4.Transition and push rod form the inclined-plane and cooperate arc groove 10 gradually to the both sides end face by the centre; First back-moving spring 8 withstands on push rod 3 ends in the arc groove 10; Have the radial hole that communicates with axial hole on the leading portion lock core 7, self-lock pin 9 is located in the radial hole, connects through oblique mechanism between its lower end and the push rod 3; Second back-moving spring 1 is pressed in self-lock pin 9 on the push rod 3, on lock embryo 6, is provided with the circumferential recess 2 that supplies self-lock pin 9 to realize the lock core self-locking with self-lock pin 9 corresponding sections.
