Description
Technical field
The utility model belongs to lock core, and in particular to a kind of improved dual-purpose lock core and its matched key.
Background technology
After existing dual-purpose lock core is on door on the market, while it are furnished with two keys, one is transferred to for engineering key
Fit up master worker to use, another handle is grasped for normal key by house-owner.After finishing completion, as long as being opened with normal key insertion lock core
Lock, engineering key, that is, calcellation cannot be unlocked.Existing dual-purpose lock core still has deficiency, and following drawback occurs in use.
1. key, engineering pin, engineering blade are on a straight line, engineering blade is spacing by engineering pin convex block, and engineering pin is the same as key one
Sample moves from the front to the back, and in finishing, door usually locates unstable state, often there is the phenomenon closed the door in door accident, yet with
Unexpected to close the door different with inertia produced by normal close the door, external force overcomes engineering pin return spring active force in the case of macroseism, makes work
Journey pin departs from engineering blade, unlocks normal key has not been used, engineering key has just failed.2. when using key, to key
The mode of spoon insertion is extremely important, if not being inserted into key by correct mode, just goes out to occur slotting key card or inserts not into key
The phenomenon of spoon.
The content of the invention
The purpose of this utility model is to provide a kind of improved dual-purpose lock core rational in infrastructure, easy to use, safe and reliable
And its matched key.
Improved dual-purpose lock core provided by the utility model, including lock tube, loaded on setting keyhole and locking side column in lock tube
Lock core, be located at along keyhole some and key on lock core and blade marble that locking side column coordinates, be located remotely from keyhole
Last blade marble of front end is switching foil pellet, is equipped with blade marble and switching foil pellet and locking side column
Matched with key V-shaped groove and convex block, switching foil pellet are separately equipped with card slot on the side of V-shaped groove；The lock core is equipped with
It is matched with the card slot and key of switching foil pellet and set the special-shaped marble of return spring.
The special-shaped marble lower end and side be respectively equipped with the key coordinate conical bullet and with the conversion
The convex block that the card slot of blade marble coordinates.
The card slot of the switching foil pellet is be located at its V-shaped groove both sides two, and the special-shaped marble is two difference
It is engaged with two card slots of the switching foil pellet.
The matched key of improved dual-purpose lock core provided by the utility model, including the first key and the second key, first
Key and the second key have and the matched identical tartar of the convex block on blade marble and switching foil pellet, the first key
Front end be equipped with and avoid the rectangle of switching foil pellet and special-shaped marble and avoid notch, the front end of the second key be equipped with boss with it is different
Type pellet is engaged.
The beneficial effects of the utility model：
The utility model is switching foil pellet to be added on the basis of existing locking side column blade lock core and with turning
Change blade marble cooperation special-shaped marble, using two different structures first, second key respectively with switching foil pellet and
Special-shaped marble is engaged so that after the second key changes the original state of switching foil pellet, the first key can not make conversion leaf
Piece pellet restPoses, and can thoroughly prevent after using the second key unlocking, and the first key, which does not fail, remains to the technology of unlocking
Failure, and due to special-shaped marble and the cooperation position limiting structure of switching foil pellet, it is produced can thoroughly to prevent that door from surprisingly closing the door
Technical failure, its is rational in infrastructure, be not in slotting key card or insert not into the phenomenon of key, it is easy to use, securely and reliably.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.

Notch 303 is avoided, key 3B front ends are engaged equipped with boss 301 with the bullet 1003 of special-shaped marble 10.
Operation principle
1st, during original state, as shown in Fig. 2, 13 compression retracteding position spring 4 of switching foil pellet is by a special-shaped marble 10A
Convex block 1002 be engaged with one card slot 1303 and make its positioning.
2nd, unlocked using key 3A as shown in Fig. 3,4,8, after the keyhole 201 on key 3A insertion lock cores 2, on key 3A
Avoidance notch 303 do not act on switching foil pellet 13 and special-shaped marble 10, the tartar 302 on key 3A acts on blade marble
Blade marble 5 from new arrangement, is made the V grooves 502 on pellet 5 and the V-shaped groove on switching foil pellet 13 by the convex block 501 on 5
1302 in line, and for locking side column 7 under the active force of return spring 8, its V-shaped edge 701 drops into straight V grooves 502 and V
In shape groove 1302, the locking side column card slot 102 of its another side disengaging disengaging lock tube 1 is retracted into the locking side column groove 204 of lock core 2
Interior, reversing key 3A at this time can unlock.
3rd, key 3A is extracted using key 3A lockings, rotary locking cylinder 2 to origin, pellet 5 is under the active force of return spring 4
Return, locking side column 7 overcome 8 active force of return spring under the action of pellet 5, stretch into the locking side column card slot 102 of lock tube 1
Locking, because key 3A is not applied to switching foil pellet 13 and special-shaped marble 10, so switching foil pellet 13 still locate and
Original state（Referring to Fig. 2）.
4th, unlocked using key 3B as shown in Fig. 5,6,9, its boss 301 acts on bullet after key 3B insertion lock cores 2
1003 overcome return spring 11 to push up special-shaped marble 10, and the convex block 1002 of special-shaped marble 10 departs from switching foil pellet 13
Card slot 1303, while the tartar 302 on key 3B is matched somebody with somebody with the convex block 501 on pellet 5 and the convex block 1301 of switching foil pellet 13
Close, pellet 5 is made into the V grooves 502 on pellet 5 with turning from new arrangement in the case where keeping 13 position of switching foil pellet motionless
Change V grooves 1302 on blade marble 13 in line, the V-shaped edge 701 of locking side column 7 is dropped into V grooves 502 and V-shaped groove 1302,
Rotation key 3B can unlock at this time.
5th, using key 3B lockings as shown in fig. 7, during extracting key 3B, the first boss 301 by key 3B will
On the top of special-shaped marble 10, the convex block 1002 on special-shaped marble 10 is kept to depart from the state of card slot 1303 on switching foil pellet 13,
It is spacing due to no tartar 302, the return under 4 active force of return spring of switching foil pellet 13 at this time, then blade marble 5
Also the spacing return under 4 active force of return spring of tartar 302 is departed from, locking side column 7 is in blade marble 5 and switching foil pellet
Overcome the effect of return spring 8 to be caught in the locking side column groove 102 of lock tube 1 under the action of 13, complete locking.Switching foil pellet
After 13 returns, another card slot 1303 thereon is just engaged with the convex block 1002 on another special-shaped marble 10B, makes its quilt
Positioning is unable to side-to-side movement, even if non-matching key can be prevented with the tartar identical with key 3A, 3B, because cannot be with special-shaped bullet
Convex block 1002 on son 10 is engaged and can not also unlock；Unlocked prevented also from using instrument by stirring blade marble, because work
Tool can not stir switching foil pellet 13.
5th, key 3A front ends are since equipped with notch 303 is avoided, it is left can not also to act on switching foil pellet 13 when reusing
The dynamic movement in the right side and special-shaped marble move up and down, i.e., switching foil pellet 13 can not be made to return to original state, so using key
Key 3A fails after 3B.
During finishing, key 3A gives finishing master worker and uses, and key 3B is used by house-owner oneself.
