Description

A kind of two-sided key idle-run lock head

Technical field:

The utility model relates to a kind of lock, and in particular, it relates to a kind of tapered end.

Background technology:

Existing ball lock head majority by housing, be enclosed within that rotary lock core and pellet shot from a slingshot etc. thereof constitute in the housing, housing and lock core corresponding vertically have several pellet shot from a slingshot holes, a spring is put in each pellet shot from a slingshot hole, a housing pellet shot from a slingshot, a lock core marble.During locking, housing pellet shot from a slingshot insertion lock core card in various degree stops lock core to rotate between housing and lock core.The lock of this structure can be twisted off when lock core is inserted the pellet shot from a slingshot that stops lock core to rotate when keyhole is done powerful reversing by special instrument, makes this lock lose anti-theft feature.

Summary of the invention:

The purpose of this utility model provides a kind of two-sided key idle-run lock head that can overcome existing defective in the prior art, its lock core is in idling conditions when locking, insert unlocking tool or other objects, can rotational lock core, but can not unblank, this lock can effectively be defendd improper unblanking such as brute force is unblanked, technology unlocking, and theftproof is very good, and its key tow sides tartar is identical, when unblanking, key need not divide direction, inserts and just can open, and is very convenient.

The utility model is achieved by the following technical solution: it is by housing, be enclosed within formations such as the interior rotary lock core of housing, described lock core, constitute by internal cylinder and outer lock core, internal cylinder is enclosed within the outer lock core, outer lock core is the main body of unblanking, vertically have several locking plate grooves in internal cylinder, it is folded mutually that each locking plate groove is put into two front and back, the locking plate that opening direction is opposite each other and a spring have notch on the outside of each locking plate, have secondary bullet groove corresponding to the notch place, built-in secondary pellet shot from a slingshot, the inner shape of secondary pellet shot from a slingshot and the shape of locking plate notch match, and have the clutch cotter way at outer lock core corresponding to secondary bullet groove, built-in on-of pin, in housing, have lock slots corresponding to clutch cotter way place, built-in one to several springs and to several pellets shot from a slingshot, its key tow sides tartar is identical.

The two-sided key idle-run lock head of the utility model is in idling conditions when locking, when foreign matter or unlocking tool insert rotational lock core arbitrarily, but can not unblank, so this lock can effectively be defendd improper unblanking such as brute force is unblanked, technology unlocking, theftproof is very high, and its key tow sides tartar is identical, when unblanking, key need not divide direction, inserts and just can open.

The specific embodiment:

Fig. 1-the 3rd, first embodiment of the present utility model is made of housing 1, outer lock core 2, internal cylinder 3, locking plate 5 etc.Described internal cylinder 3 is enclosed within the outer lock core 2, outer lock core 2 is the main body of unblanking, vertically have several locking plate grooves 4 in internal cylinder 3, each locking plate groove 4 is put into folded mutually opposite each other locking plate 5 and the spring 7 of opening direction in two front and back, the centre of each locking plate 5 has keyhole 18, an angle of keyhole 18 is provided with projection 17, have notch 8 on the outside of locking plate 5, corresponding to notch 8 places, have secondary bullet groove 9 in internal cylinder 3, built-in secondary pellet shot from a slingshot 10, the inner 19 shapes of secondary pellet shot from a slingshot 9 and the shape of locking plate notch 8 match, have clutch cotter way 11 at outer lock core 2 corresponding to secondary bullet groove 9 places, built-in on-of pin 12 has lock slots 13 corresponding to clutch cotter way 11 places in housing 1, have one in the lock slots 13 to several pellet shot from a slingshot holes 14, spring 16 and pellet shot from a slingshot 15 are equipped with in the inside, and its key 20 is a tabular, front and back has identical tartar 21, when unblanking, key need not divide direction, inserts and just can open.

As shown in Figure 2, when unblanking, key 20 inserts, under the promotion of tartar 21, locking plate 5 moves, and the notch 8 of all locking plates 5 is all to chief and vice pellet shot from a slingshot, under the effect of return spring 16, secondary pellet shot from a slingshot 10, on-of pin 12, return pellet shot from a slingshot 15 move together inwards, and the inner 19 of secondary pellet shot from a slingshot 10 falls into notch 8, and internal cylinder 3 is inserted in the inner of on-of pin 12, be stuck between internal cylinder 3 and the outer lock core 2, internal cylinder 3 and outer lock core 2 are connected as a single entity, and lock slots 13 is then withdrawed from its outer end, and twisting key 20 just can be unblanked.During locking, extract key 20, locking plate 5 moves to both sides under the effect of spring 7, its notch 8 departs from secondary pellet shot from a slingshot 10, the top is compeled secondary pellet shot from a slingshot 10 and is outwards moved, and secondary pellet shot from a slingshot 10 promotes on-of pin 12, makes the inner of on-of pin 12 withdraw from internal cylinder 3, internal cylinder 3 is in idling conditions, lock slots 13 is inserted in the outer end of on-of pin 12 simultaneously, is stuck between housing 1 and the outer lock core 2, and outer lock core 2 can not be rotated, form lock-out state, at this moment, internal cylinder 3 is in idling conditions, when foreign matter or unlocking tool insertion, can rotate internal cylinder 3, but can not unblank.
