Abstract
The utility model relates to an antitheft lock core device, comprising a lock core, a lock casing, and a marble clamping mechanism arranged in the lock core and the lock casing. The bottom of the hole for the lock core key to be inserted in is provided with a pin clamping antitheft mechanism compising a thimble penetrating the bottom of the hole for the lock core key to be inserted in off center, a resetting mechanism, an antitheft pin, and a pin slot matched with the antitheft pin and arranged on the lock casing. The utility model improves the safety of the lock core through the technical scheme, and the people can not open the lock with other tools in the usual condition because of the antitheft mechanism arranged without being known at the bottom of the lock core.
Description
Technical field
The utility model relates to a kind of anti-theft lock.
Technical background
Lockset is an indispensable safety precaution instrument in people's daily life, lockset commonly used at present, and its lock core adopts the cylinder type rotational structure more.For tightening security, reduce mutual opening rate, its technical measures generally concentrate on and adopt many ribs, multiple tooth structure on the key, and on the equipped mutually multi-faceted billiards structure, 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 have added together in the lock core bottom, and pin blocks burglar-proof mechanism.
The utility model is to adopt following scheme to realize: a kind of anti-theft lock device, include lock core, lock housing and be located at lock core and lock housing in pellet shot from a slingshot screens mechanism, be provided with pin card burglar-proof mechanism in lock core key patchhole bottom, pin card burglar-proof mechanism include thimble that off-centre is placed through lock core key patchhole bottom, resetting-mechanism, anti-steal and sell and with the anti-cotter way that is equipped with on lock housing of stealing and selling.
Further setting of the present utility model is: described resetting-mechanism includes gland and back-moving spring, and gland is fixedly installed on the end face of bottom of lock core key patchhole, and back-moving spring is arranged between gland and anti-the stealing and selling; The described anti-shape of stealing and selling can be " one " or " ten " shape.
Overcome the deficiency that traditional structure lock core in the past exists by above technical scheme the utility model, the utility model has added burglar-proof mechanism one in the bottom of lock core key patchhole, has produced following beneficial effect: 1, effectively prevented technology unlocking; 2, obviously increased the safety of lock; 3, compare with the lock core of traditional structure, cost of production, production technology and technology do not have very big difference.
Description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As illustrated in figs. 1 and 2, a kind of anti-theft lock device, include lock core 2, lock housing 1 and be located at lock core 2 and lock housing 1 in pellet shot from a slingshot screens mechanism, the pellet shot from a slingshot screens mechanism of the utility model middle finger refers generally to pellet shot from a slingshot and the spring in the cylinder lock, but also can be the screens of copper sheet pellet shot from a slingshot and the screens of crescent moon pellet shot from a slingshot or both combinations in copper sheet lock and the crescent lock, in order to improve the antitheft grade of lock core 2, a pin card burglar-proof mechanism is set in the bottom of lock core 2 key insertion holes; Pin card burglar-proof mechanism include thimble 5, resetting-mechanism, anti-steal and sell 4 and with anti-4 cotter ways 6 that are equipped with on lock housing 1 of stealing and selling; Thimble 5 passes lock core key patchhole bottom and departs from its circle centre position, is backed down by the technical opening instrument to prevent thimble 5 as far as possible, anti-steal and sell 4 and is connected with thimble 5.Resetting-mechanism includes gland 3 and back-moving spring 7, gland 3 is fixedly installed on the end face of bottom of lock core 2 key insertion holes, distance between itself and the end face is more than or equal to anti-4 the thickness of stealing and selling generally speaking, and back-moving spring 7 is arranged on gland 3 and anti-stealing and selling between 4.Under lock-out state, prevent that stealing and selling 4 has at least an end to be arranged in the cotter way 6 of lock housing 1, under unlocking condition, key inserts, and backs down pellet shot from a slingshot screens mechanism and pushes thimble 5 to bottom, anti-ly steals and sells 4 and is ejected the cotter way 6 of lock housing 1 by thimble 5, so, lock core 2 can rotate, and unblanks.Prevent that generally stealing and selling 4 is " one " or " ten " shapes, what other shapes can achieve the above object certainly also can realize.
