Abstract
The utility model relates to a side pillar internal pressure type theft-proof billiard lock, which comprises a lock body (1), a lock core (5), billiards (3) and a locking side pillar (14), wherein, each billiard (3) is provided with a circle of V-shaped concave grooves (4) at different positions and a key (12) causes the V-shaped concave grooves (4) of the billiards (3) to entirely coincide or dislocate to drive the locking side pillar (14) to move, and therefore, the rotation of the lock core (5) can be controlled or the lock core (5) is tightly clamped. The lock can not use an unlocking tool which is not matched with a key to simultaneously position each billiard (3) and entirely coincide the V-shaped concave grooves (4) on the billiards so that the lock can not be opened. Consequently, the billiard lock has the advantages of high safety and good theft-proof property.
Description
The utility model belongs to a kind of lockset, particularly relates to a kind of cylinder lock set.
Cylinder lock is a kind of common lockset, common cylinder lock locks lock core by pellet shot from a slingshot and rotates, each pellet shot from a slingshot group in the lock is by two compositions, when unblanking, the contact surface of two pellets shot from a slingshot overlaps with the contact surface of lock core and lock body, and lock core can rotate relative to lock body, during locking, the contact surface of two pellets shot from a slingshot does not overlap with the contact surface of lock core and lock body, because the barrier effect of pellet shot from a slingshot, lock core cannot rotate.This problem that is latched in is, open with the unlocking tool cover of non-matching key easily, as master key, Unlocking gun etc., because two pellets shot from a slingshot that these unlocking tools can both make each pellet shot from a slingshot group are one by one in the dislocation of the contact surface place of lock core and lock body, all overlap with the contact surface of lock core and lock body until their contact surface.Therefore, the security performance of this cylinder lock and theftproof performance are all bad.
The purpose of this utility model provides a kind of new cylinder lock, and this cylinder lock has the locking device that the control lock core after the improvement rotates, and its security performance and theftproof performance all lock than existing pellet shot from a slingshot.
The technical solution of the utility model comprises lock body, lock core, pellet shot from a slingshot, the lock body inboard has the square groove, have the side column groove on the lock core, the side column groove is inboard to communicate with the side in pellet shot from a slingshot hole, and with pellet shot from a slingshot hole approximate vertical, the side column groove outside can be corresponding with the square groove of lock body inboard, each pellet shot from a slingshot all has a circle ∨ type groove on diverse location, be provided with locking side column in the side column groove, the inboard of locking side column is the ∧ type, can match with the ∨ type groove on the pellet shot from a slingshot, the outside of locking side column is a square, can match with the square groove of lock body inboard, and locking side column is provided with step, with be fixed with pressing plate on the corresponding lock core side column of the step groove outside, between pressing plate and side column step, be provided with spring.
During above-mentioned cylinder lock locking, the side column groove on the lock core is corresponding with the square groove of lock body inboard, and the inboard of locking side column is under the compressing of pellet shot from a slingshot outer wall, and its outside is stretched in the lock body square groove, and lock core can not rotate.When unblanking, after key inserts lockhole, tartar on the key forces the shift in position of each pellet shot from a slingshot, at this moment, the ∨ type groove on the pellet shot from a slingshot all overlaps, and is on the straight line, locking side column is under the effect of spring, its ∧ type inboard is slipped in the ∨ type groove on the pellet shot from a slingshot, withdraws in lock body square groove in the outside of locking side column, and lock core can rotate.
The utility model is because the locking device that has adopted locking side column to rotate as the control lock core, with the unlocking tool of non-matching key each pellet shot from a slingshot located simultaneously, and the ∨ type groove on it all overlapped, so lock can not be opened.Therefore, this cylinder lock has good safety and theftproof.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Accompanying drawing discloses an embodiment of the present utility model, cylinder lock comprises lock body 1, lock core 5, pellet shot from a slingshot 3, marble spring 6, spring die 7, lock body 1 inboard has square groove 9, have side column groove 15 on the lock core 5, side column groove 15 inboards communicate with the side in pellet shot from a slingshot hole 16, and with pellet shot from a slingshot hole 16 approximate vertical, side column groove 15 outsides can be corresponding with the square groove 9 of lock body 1 inboard, each pellet shot from a slingshot 3 all has a circle ∨ type groove 4 on diverse location, be provided with locking side column 14 in the side column groove 15, the inboard 8 of locking side column 14 is the ∧ type, can match with the ∨ type groove 4 on the pellet shot from a slingshot 3, the outside of locking side column 14 is a square, can match with the square groove 9 of lock body 1 inboard, the two ends of locking side column 14 are provided with step 13, and are fixed with pressing plate 11 on step 13 corresponding lock core side column grooves 15 outsides, are provided with spring 10 between pressing plate 11 and side column step 13.
Lock among the figure is in opening, tartar 2 on the key 12 is arranged each pellet shot from a slingshot 3 in order, ∨ type groove 4 on the pellet shot from a slingshot 3 all overlaps, locking side column 14 is under the effect of spring 10, its ∧ type inboard 8 is slipped in the ∨ type groove 4 on the pellet shot from a slingshot 3, locking side column 14 is withdrawn in the lock core 5 in the square groove 9 of lock body 1, and lock core 5 can rotate.During locking, the scale of alignment lock core 5 and lock body 1, when key 12 was extracted in the direction of arrows, pellet shot from a slingshot 3 moved down under the effect of spring 6, forced locking side column 14 to move in the square groove 9 that stretches into lock body 1 along the direction of arrow, and lock core 5 is stuck.
