Abstract

The utility model relates to a lock with locking plate idling which comprises a shell, a core which can be rotated and is sleeved in the shell, a locking plate and a clutch pin, wherein the core includes a columniform inner core and a columnar outer core which the inner core is sleeved in. The outer core is the lock body. When in unlocking, insert the key and then the inner core and the outer core are linked as a whole, then turn the key. When in locking, the inner core and the outer core are separated, and then the inner core is idling. When the lock is inserted by other foreign material or the key mismatched with the core, the core can be rotated at will, but can not open the lock, thereby the lock can defend the improper opening to the core such as the forced and technical opening and is strong in theft-protecting.

Description

A kind of page of sheet idle-run lock head

1. technical field:

The utility model relates to a kind of lockset, relates in particular to the lock head structure in the lockset.

2. background technology:

Invent artificial Luo Guoji, the patent No. is: ZL 00 2 47224.4, and name is called " antitheft sylinder ", and notice of authorization day is: the Chinese utility model patent in December 12 calendar year 2001 discloses a kind of theftproof lock.This lock is to have several locking plate grooves in lock core, it is folded mutually that two front and back are housed in each locking plate groove, and opening direction is opposite each other, the locking plate of two shared springs, every locking plate to having V-notch, makes this lock have the function of pellet shot from a slingshot switch and locking plate switch simultaneously corresponding to lock core marble groove one.This lock can be opened by defense technique really, but because it does not have lost motion functionality, so when its lock core is reversed as brute force by special instrument insertion, stop the pellet shot from a slingshot of lock core rotation to be twisted off, makes this lock by unnormal unlocking, thereby lose anti-theft feature.

3. summary of the invention:

The purpose of this utility model be to provide a kind of can be in overcoming above-mentioned patented technology the idle-run lock head of existing defective.It is to increase an outer lock core cylindraceous between the lock core of above-mentioned patent " antitheft sylinder " and tapered end housing, and lock core originally is sleeved in the outer lock core, forms inside and outside lock core structure.Under blocking, internal cylinder is in idling conditions, can rotate arbitrarily and this lock can not be unlocked, improper unblanking such as the brute force that can effectively defend to carry out at lock core is unblanked, technology unlocking.

The utility model is achieved by the following technical solution:

It by housing, be enclosed within that rotary lock core and pellet shot from a slingshot etc. constitute in the housing, wherein said lock core is made up of internal cylinder and outer lock core, its special sex character is: columniform internal cylinder is sleeved in the columnar outer lock core, have several locking plate grooves in internal cylinder, folded mutually opposite each other locking plate and the spring of opening direction in two front and back is housed in each locking plate groove, every locking plate to having V-notch, has keyhole corresponding to lock core marble one in the middle of the locking plate; Have the lock core marble groove in internal cylinder perpendicular to locking plate groove place, built-in lock core marble; Have the clutch cotter way at outer lock core corresponding to the lock core marble place, built-in on-of pin; Have lock slots at housing corresponding to the on-of pin place, have return pellet shot from a slingshot hole one in the lock slots to several, return spring and return pellet shot from a slingshot are equipped with in the inside.

The lock core of the utility model idle running lock is made up of inside and outside lock core, and when unblanking, inside and outside lock core is connected as a single entity, and twisting key turns internal cylinder can drive outer lock core and will lock unlatching; During locking, inside and outside lock core separates, and internal cylinder can be rotated arbitrarily, and this lock can not be unlocked.So improper means of unblanking such as the brute force that this lock can effectively be defendd to carry out at lock core is unblanked, technology unlocking.

5. the specific embodiment:

Be a kind of embodiment page or leaf sheet idle-run lock head of the present utility model shown in Fig. 1-3, it is made of housing 1, outer lock core 2, internal cylinder 3, locking plate 5, lock core marble 10, on-of pin 12, return pellet shot from a slingshot 15 etc.It is characterized in that: columniform internal cylinder 3 is sleeved in the columnar outer lock core 2, outer lock core 2 is the main body of unblanking, internal cylinder 3 has keyhole 18 and several locking plate grooves 4, adorn the folded mutually opposite each other locking plate 5 of opening direction in two front and back in each locking plate groove 4, with a spring 7, locking plate 5 to having V-notch 8, has keyhole 18 corresponding to lock core marble 10 1 in the middle of the locking plate 5; Have lock core marble groove 9 in internal cylinder 3 perpendicular to locking plate groove 4 places, built-in lock core marble 10; Have clutch cotter way 11 at outer lock core 2 corresponding to lock core marble 10 places, built-in strip shape body on-of pin 12; Have lock slots 13 at housing 1 corresponding to on-of pin 12 places, have return pellet shot from a slingshot hole 14 1 in the lock slots 13 to several, return spring 16 and return pellet shot from a slingshot 15 are equipped with in the inside.

When unblanking, when key 18 inserts, under the promotion of spoon tooth, locking plate 5 moves, make the V-notch 8 of all locking plates 5 all align the inner of lock core marble 10, under the effect of return spring 16, lock core marble 10, on-of pin 12, return pellet shot from a slingshot 15 moves together inwards, the inner of lock core marble 10 falls into V-notch 8, and the outer end of lock core marble 10 is lower than internal cylinder 3 surfaces, and the lock slots 4 that housing 1 is then withdrawed from internal cylinder 3 its outer ends is inserted in the inner of on-of pin 12, surperficial equal with outer lock core 2, 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, twisting key 18 rotation internal cylinder 3 can drive outer lock core 2 and will lock unlatching.

During locking, extract key 18, locking plate 5 moves to both sides under the effect of spring 7, its V-notch 8 departs from lock core marble 10, lock core marble 10 is compeled on the top, lock core marble 10 and on-of pin 12 are outwards moved together, contact surface between the inner of the outer end of lock core marble 10 and on-of pin 12 just with internal cylinder 3 and outer lock core 2 between fitting face equal, the outer end of on-of pin 12 is stretched in the lock slots 4, on-of pin 12 is stuck between outer lock core 2 and the housing 1, form lock-out state, at this moment, block without any object between internal cylinder 3 and the outer lock core 2, be in released state fully, internal cylinder can be rotated arbitrarily, and this lock can not be unlocked.
