Description

A kind of combined anti-theft lock device

Technical field

The utility model relates to a kind of anti-theft lock, is meant a kind of combined anti-theft lock especially.

Technical background

Lockset is an indispensable safety precaution instrument in people's daily life, lockset commonly used at present, single cylinder type rotational structure or the blade inserting rotational structure of the many employings of its lock core, all there is shortcoming separately in this single structure, as cylinder type, it is very easy to be gone out pellet shot from a slingshot by the crochet hook hook, blade inserting, and this lock is turned on easily by force.For tightening security, reduce mutual opening rate, their technical measures generally concentrate on and adopt many ribs, multiple tooth structure on the key, and on the structure of the multi-faceted single pellet shot from a slingshot that is equipped with mutually, said structure certainly reduces mutual opening rate, but this technology has allowed most people know, truly be difficult to reach its safe coefficient, certainly also exist some locksets of other form, such as coded lock, electronic password lock, but their lock core also lock core with traditional is the same, has just added some miscellaneous functions at other positions of lock housing.

Summary of the invention

At the technical deficiency of existing lockset lock core, the purpose of this utility model is to provide a kind of method that is provided with two kinds of burglar-proof mechanisms on lock core jointly, makes lock be difficult to open with other instruments and Fei Ben lock key.

The utility model is to adopt following scheme to realize: a kind of combined anti-theft lock device, it includes lock core, lock housing, is provided with pellet shot from a slingshot screens mechanism and inserted sheet screens mechanism on lock core and lock housing simultaneously.

Further setting of the present utility model is: described inserted sheet screens mechanism is made up of the copper sheet groove and the copper sheet that are arranged in lock core and the lock housing, described pellet shot from a slingshot screens mechanism is made up of the bullet groove, pellet shot from a slingshot and the back-moving spring that are arranged in lock core and the lock housing, and its copper sheet groove becomes right-angled intersection to distribute with bullet groove; The right-angled intersection at interval of copper sheet groove and bullet groove distributes; On lock core and lock housing, be provided with anti-blocking mechanism in addition, described anti-blocking mechanism includes sheet and back-moving spring under the crescent moon last slice that is arranged in the crescent moon film trap, the crescent moon, a crescent moon last slice end is a convex globoidal, its radian is consistent with the radian of lock core, sheet one end is a cancave cambered surface under the crescent moon, its cancave cambered surface holds with the convex globoidal of crescent moon last slice and cooperates, and the other end is connected with back-moving spring.

Overcome the deficiency that single structure lock core in the past exists by above technical scheme the utility model, carried out the combination of two kinds of structures, produced following beneficial effect: prevented that 1, external force from reversing the destructiveness of lock core by force and unblank; 2, obviously increased the safety of lock; 3, compare with the lock core of single structure, cost of production, production technology and technology do not have tangible difference.

The specific embodiment

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

As described in Fig. 1, Fig. 2, a kind of combined anti-theft lock device includes lock core 2, lock housing 1, is provided with pellet shot from a slingshot screens mechanism and inserted sheet screens mechanism on lock core 2 and lock housing 1 simultaneously.Wherein pellet shot from a slingshot screens mechanism is the same with general cylinder lock, includes the bullet groove 41, pellet shot from a slingshot 4 and the spring that are arranged in lock core 2 and the lock housing 1, and inserted sheet screens mechanism is made up of the copper sheet groove 31 and the copper sheet 3 that are arranged in lock core 2 and the lock housing 1; 41 one-tenth right-angled intersections of copper sheet groove 31 and bullet groove distribute, and in order to reach optimum efficiency, when making, copper sheet groove 31 and bullet groove 41 are arranged to right-angled intersection at interval distribute; In order to prevent that lock core 2 key insertion holes from being stopped up by foreign matter, insert nose end at it and be provided with anti-blocking mechanism in addition, it includes crescent moon last slice 5, sheet 6 and back-moving spring 7 under the crescent moon, crescent moon last slice 5 one ends are convex globoidal, its radian is consistent with the radian of lock core 2, the end that the other end of crescent moon last slice 5 promptly contacts with key is an arc surfaced, be convenient to the insertion of key, the convex globoidal of the cancave cambered surface of sheet 6 and crescent moon last slice 5 holds and is connected under the crescent moon, when unlocking condition, sheet 6 is headed in the lock housing 1 under the crescent moon, when locking states, the junction of the convex globoidal of the cancave cambered surface of sheet 6 and crescent moon last slice 5 is positioned at lock core 2 under the crescent moon, and back-moving spring 7 is headed into crescent moon last slice 5 in the lock core 2 by sheet under the crescent moon 6, blocks key insertion hole.
