Abstract

A security lock with a key introducing a method of subsection assembled of a lock core comprises a lock consisting of a lock shell, a lock core, a lock cover, a spring and billiards as well as a key matching with the lock, the lock shell is a cylinder with the front end sealed and the centre of the sealed side provided with a key hole, the lock core is arranged in the cylinder of the lock shell and is a coaxial combination formed by a plurality of columniform lock core sections, the front end of the lock core is covered by the sealed end of the lock shell except for the key hole; the key matching with the lock connects the key main body with ripple strips and a handle via a contraction of the key neck, the length and the section size of the key neck are corresponding with the thickness of the sealed side and the key hole of the lock shell. The utility model has the advantages of good security performance owning to the lock core side except for the key hole sealed in the lock shell and the subsection assembled of the lock core, thus being imposible to move simultaneously all sections of the lock core or jack up the billiards to open the lock, thereby effectively guarding against the theft.

Description

Sectionally assembled theftproof lock of lock core and key

Technical field: the utility model relates to sectionally assembled theftproof lock of a kind of lockset, particularly lock core and key.

Background technology: existing door lock is whole lock core spring marble structure mostly, because its lock core end exposes, do not hidden, so the thief uses easily crime work such as various MASTERKRYs to stir lock core and pellet shot from a slingshot is opened lock, so its theftproof performance is bad by lock body.

Summary of the invention:

The lock that provides a kind of theftproof performance good is provided the purpose of this utility model, and its adopts the structure of lock core segmentation combination, overcomes the above-mentioned drawback of existing spring marble door lock.

The technical solution of the utility model is sectionally assembled theftproof lock of a kind of lock core and key, it comprises the key that lock reaches and lock is supporting that is made of lock body, lock core, locking closure, spring, pellet shot from a slingshot and forms, it is characterized in that lock body is the cylinder of front end sealing, there is keyhole at the Closed End center, lock core is packed in the lock body cylinder, the lock core front end is except that the keyhole on it, and remainder is hidden by the lock body blind end, and lock core is made of a plurality of lock cylinder section coaxial combination; With the supporting key of lock is to be connected with the spoon neck of handle via one section cross-sectional constriction by the spoon body that has moire spoon strip, the thickness of the length of spoon cervical part of esophagus and cross-sectional sizes and lock body Closed End and on the keyhole cross section corresponding identical.

The specific embodiment:

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

Sectionally assembled theftproof lock of a kind of lock core and key, it comprises the lock that is made of lock body [1], lock core [2], locking closure [8], spring [7], pellet shot from a slingshot [5], [6] and and locks supporting key and form.Referring to accompanying drawing 1.

Lock body [1] is the cylinder of front end sealing, and there is keyhole [12] at Closed End [14] center, and lock core [2] is packed in lock body [1] cylinder, and the lock core front end is except that the keyhole on it [13], and remainder is by lock body front end face [14] shield.Referring to accompanying drawing 1,3.

Lock core [2] is sectionally assembled structure, and lock core [2] is formed by plurality of sections lock cylinder section coaxial combination, and present embodiment is that preceding lock core section [4] constitutes with [5] two lock core sections of rear lock core section, referring to accompanying

drawing

1,4,5.

Lock body [1], lock core [2] are provided with the width of cloth to the slotted eye [3] that is communicated with axially-aligned, are 4 rows in the present embodiment.Referring to accompanying drawing 1,2.Spring [7], pellet shot from a slingshot [5], [6] are housed in the slotted eye [3]; Plug [4] is equipped with in slotted eye [2] outer end of lock body [1].

With the supporting key of lock is to be connected with the spoon neck [17] of handle [18] via one section cross-sectional constriction by the spoon body [16] that has moire spoon strip [15], the length L of spoon neck [17] section and cross sectional shape big or small with lock body [1] Closed End [14] thickness H and on keyhole [12] cross section corresponding identical.Referring to accompanying

drawing

6,7.

Lock body [1], lock core [2] the upper edge circumference width of cloth are provided with the slotted eye [3] that 1-10 arranges mounting spring, pellet shot from a slingshot more to diverse location, for example can be 1 row or 2 row's radial symmetric distributions, or 3 row's circumference uniform distributions, respectively referring to accompanying drawing 8,9,10.It is uniform at the circumference 90 ° of central angles that stagger mutually that present embodiment is 4 emissions groove holes.Every emissions groove hole [3] along lock shaft to arrangement, referring to accompanying drawing 1,2; With the supporting width of cloth of circumference on the key of lock to the corresponding ripple tooth bar [15] that is provided with vertically that is provided with and locks slotted eye [3] row number equal number.Referring to accompanying drawing 4,7.The keyhole of locking [12], [13] are for axially running through the through hole of lock body [1], lock core [2].

The utility model has the advantages that to have good theftproof performance, because the lock core end face all is enclosed in except keyhole In the lock body end face, and lock core is sectional combination structure, therefore namely uses the crime work such as various MASTERKRYs also Can't stir simultaneously each section lock core, jack-up pellet, open lock, can be effectively antitheft.
