Abstract
The invention discloses a grading lock pin with double extending groove, which is characterized by the following: comprising a front lock pin (1)and a back lock pin (2); setting the back lock pin (2)as back lock case (21), back locating slot (22)to locate door, back key slot (24)in the back lock case and back marble pore (25); locating the back lock pin (2)and the front lock pin in same line; locating the back key groove (24)and the front key groove (14)in same line; setting the back marble pore (25)and the front marble pore (15)in same direction; arranging a extending groove (241)on the upper end or lower end of the back key groove (24).
Description
Technical field
The present invention relates to a kind of lock, relate in particular to the lock core of this lock.
Background technology
Daily lock major part is single core list key, and it is convenient to open, but poor safety performance is easily pried open with simple tool by stealer.
It is to adopt locked groove to drive pellet shot from a slingshot to reach the purpose of unblanking that a kind of lock is arranged in the prior art, and just the user inserts locked groove in the lock core with key, and key moves pellet shot from a slingshot.
How to reach on the basis of this lock core that stealer can not be unblanked easily is the problem that the designer will solve.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of two expansion slot segmentation lock cores that have, and are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: a preceding lock core; Lock core comprises before described: preceding lock housing, with prelocalization groove, lockhole, the preceding key in preceding lock housing and the preceding pellet shot from a slingshot hole of door location; Also comprise a rear lock core; Described rear lock core comprises: the back lock housing, with the back locating slot of door location, back key and pellet shot from a slingshot hole, back in the lock housing of back; Described rear lock core and preceding lock core are on same line and close with it; Back key and preceding key are on same line, and back pellet shot from a slingshot hole and preceding pellet shot from a slingshot hole are on same direction; Upper and lower end in the back key also comprises an expansion slot respectively.
Compared with prior art, the invention has the beneficial effects as follows: key must drive two lock cores and rotate simultaneously and can unblank, stealer can't be used tamper tool easily, and two expansion slot make stealer can't use the thing rotational lock core narrower than key to unblank simultaneously in rear lock core.
Description of drawings
Fig. 1 is a structure chart of the present invention;
Fig. 2 is a cut-away view among Fig. 1;
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
By Fig. 1, Fig. 2 as seen: the present invention includes: a preceding lock core 1; Lock core 1 comprises before described: preceding lock housing 11, with prelocalization groove 12, lockhole 13, the preceding key 14 in preceding lock housing and the preceding pellet shot from a slingshot hole 15 of door location; Also comprise a rear lock core 2; Described rear lock core 2 comprises: back lock housing 21, with the back locating slot 22 of door location, back key 24 and pellet shot from a slingshot hole, back 25 in the lock housing of back; Described rear lock core 2 and preceding lock core 1 are on same line and close with it; Back key 24 and preceding key 14 are on same line, and back pellet shot from a slingshot hole 25 and preceding pellet shot from a slingshot hole 15 are on same direction; Upper and lower end in back key 24 also comprises an expansion slot 241 respectively;
Described expansion slot 241 is identical with the length of back key 24;
Settle two locating holes 131 that are used for normal key on the described lockhole 13.
Preceding lock core and rear lock core constitute the agent structure of whole lock core, and wherein rear lock core is fixedlyed connected with external door by the back locating slot, and preceding lock core is fixedlyed connected with door by the prelocalization groove.Former and later two lock core devices make key must drive two lock cores and rotate simultaneously and can unblank that stealer can't be used tamper tool easily, and expansion slot make stealer can't use the thing rotational lock core narrower than key to unblank simultaneously.
During use, only need that key is inserted preceding key by lockhole and rotate the purpose that can reach the locking of unblanking with the back key.
