Abstract
The utility model belongs to the field of blade-type padlocks, and provides a blade lock with a lock cylinder capable of idling. The blade lock is suitable for households, offices, industry and commerce, tourist industry and the like, and is prevented from being unlocked by a non-original key or damaged by violence. The blade lock adopts the technical scheme that the lock can be unlocked through an original key; and when the lock is unlocked by the non-original key, the lock cylinder can only idle and the lock can not be unlocked. The blade lock is characterized in that a placeable rotating blade, positioning beads and a pressure spring are mounted on the lock cylinder; the placeable blade is a cylinder with a key hole in the center; concave positions are arranged on the excircle surface of the placeable blade and matched with the positioning beads; and the pressure spring is mounted in the position of the lock cylinder corresponding to the concave positions of the placeable rotating blade, so that the positioning beads can be pressed in the concave positions of the placeable rotating blade. The working principle of the blade lock lies in that when the lock cylinder is twisted forcefully by the non-original key, all rotating blades rotate with the key simultaneously, and the relative positions of arc-shaped slots of the rotating blades do not change, so that the lock bolt can not fall in the arc-shaped slots, the lock cylinder is still clamped fixedly by the lock bolt and can not rotate, and the lock can not be unlocked. The blade lock has the advantages of simple and reliable structure and convenience in use; and as the placeable rotating blade can be mounted in any position of the lock cylinder and the placeable rotating blade is adopted, the processing technique of components of the lock is not needed to be changed, the jig fixture is not needed to be increased, and the cost is lowered.
Description
Technical field
The page or leaf mortice lock that a kind of lock core can dally belongs to page or leaf chip padlock field, is applicable to uses such as family, office, industry and commerce, tourism.
Background technology
The kind of mechanical lock is a lot, probably can be divided into a page mortice lock, the lock of cylinder lock and magnetic class, the structure of page or leaf sheet padlock is mainly by lock body, lock core, locking bolt, rotating page or leaf sheet and fixation leaf forms, lock body entangles lock core, lock core can rotate, rotating page or leaf sheet and fixation leaf alternately is installed in the hole of lock core, be locked in when using (closure state), in the groove of locking bolt between lock body and lock core, lock core can not be rotated, lock can not leave, unblank, with the keyhole in the key reeve page or leaf sheet, tartar on the spoon can turn to the position corresponding with locking bolt to the deep-slotted chip breaker that rotates the page or leaf sheet, makes locking bolt leave lock body and is absorbed in the deep-slotted chip breaker that rotates the page or leaf sheet, so lock core can be unblanked by key turns.
The security reliability of existing lock has problem, not only can use skilled unlocking, also can unblank by force, as: available non-original key inserts lock core, reverses lock core by force and destroys the page or leaf sheet, also can borrow some instruments, destroy the retaining element of lock core or lock body, powerfully take out lock body or lock core and unblank.At present, also there are some locks to adopt the structure of idle-run lock pins to prevent technical or violence nature is unblanked, as Chinese patent application number: 200710035991.7 (titles: a kind of idle-run lock head); 200910043795.3 (titles: a kind of clutch structure of idle-run lock pin) and for example.Above-mentioned patent is a cylinder lock, in order to realize idle running, section lock core (the back segment lock core connects dead bolt) before and after adopting, before and after the connection of section lock core be by the lock pin on the control back segment lock core along lock core shaft to the structure that enters or withdraw from the leading portion lock core, a realization front and back section lock core rotates simultaneously or has only the leading portion lock core to rotate, but not original key can only make the leading portion Lock cylinder idling, and the back segment lock core can not change, so non-original key is not driven lock.
The structure of above-mentioned energy idle-run lock pin is complicated, and can not be used for the lock of page chip architecture.
Summary of the invention
The page or leaf mortice lock that a kind of lock core that the utility model proposes can dally its objective is to stop with non-former spoon and opens or violence damage page or leaf mortice lock.
The technical solution adopted in the utility model is: can unblank with former spoon; When non-former spoon was unblanked, lock core can only dally, and can not unblank.
The page or leaf mortice lock that a kind of lock core can dally, the structure of page or leaf mortice lock is mainly by lock body, lock core, rotate page or leaf sheet and fixation leaf, latch hook is formed, lock body entangles lock core, lock core can rotate, rotating page or leaf sheet and fixation leaf alternately is installed in the hole of lock core, it is characterized in that being equipped with on the lock core an orientable rotation page or leaf sheet and positioning bead and stage clip, orientable rotation page or leaf sheet is the cylinder that there is keyhole at the center, its outer round surface has recess to cooperate with positioning bead, stage clip is installed in orientable and rotates on the corresponding lock core position of page or leaf sheet recess, can be pressed in positioning bead in the recess of orientable rotation page or leaf sheet.
The page or leaf mortice lock that above-mentioned a kind of lock core can dally is characterized in that the described orientable page or leaf sheet that rotates is one that rotates in the page or leaf sheet.
The page or leaf mortice lock that described a kind of lock core can dally is characterized in that described stage clip can be helical compression spring or opening elasticity pressure ring.
The page or leaf mortice lock that above-mentioned a kind of lock core can dally is characterized in that described opening elasticity pressure ring is installed in the lock core cannelure corresponding with orientable rotation page or leaf sheet recess.
The page or leaf mortice lock that described a kind of lock core can dally is characterized in that described helical compression spring is installed in the lock core hole corresponding with orientable rotation page or leaf sheet recess.
The page or leaf mortice lock that described a kind of lock core can dally is characterized in that described orientable position of rotating the page or leaf sheet can be installed in any position of lock core.
The page or leaf mortice lock that described a kind of lock core can dally is characterized in that described positioning bead has 1-4.
The page or leaf mortice lock operating principle that a kind of lock core of the present utility model can dally:
When non-former spoon object firmly twists lock core, the orientable page or leaf sheet that rotates rotates the pressure that positioning bead imposes on the recess owing to the effect of torsion overcomes stage clip, all rotate the page or leaf sheet and also follow key to rotate simultaneously, rotate not change of relative position between the page or leaf sheet deep-slotted chip breaker, therefore, locking bolt can not fall into deep-slotted chip breaker, so lock core still can not be rotated by locking bolt is stuck, lock can not leave, thereby, guaranteed the safety that can not unblank and lock.
The described orientable page or leaf sheet that rotates is one that rotates in the page or leaf sheet.
The utility model is simple in structure, reliable, and is easy to use, because orientable position of rotating the page or leaf sheet can be installed in any position of lock core and can use and rotate the page or leaf sheet, so need not change lock processing technology of components and increase worker die clamper, it is low to reduce cost.
