Abstract
The invention relates to a locking plate lock with a lock stop locking mechanism. The locking plate lock comprises a lock body, a lock cylinder which is rotatably arranged in the lock body in a moving matching mode, locking plates and the lock stop locking mechanism. The lock stop locking mechanism comprises a groove slit, a locking side groove arranged on the inner wall of the lock body, an unlocking groove arranged beside a locking plate locking member and a sheet-like locking lock stop which can slide in a channel formed by the groove slit and the locking side groove. Locking plate groove holes are arranged in parallel in the axial direction and perpendicular to the axis on the lock cylinder, a pair of locking plates is arranged in every locking plate groove hole, and every locking plate is provided with a return spring which is pushed to the end of the locking plate. The two side edges of the unlocking groove are arranged in an inclined mode. The side edge of the locking lock stop, which is opposite to the unlocking groove, is provided with a sloping surface matching with two side edges of the unlocking groove. Under the mutual action of the unlocking groove and the sloping surface of the locking lock stop, the elastic force of the return spring needs to be great enough to enable the locking lock stop to withdraw from the unlocking groove. According to the locking plate lock, the structure of the lock is simplified, the assembly is facilitated, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of tapered end, particularly have the blade locking head of stop locking mechanism.
Background technology
In order to improve the theftproof performance of blade locking head, increase opening difficulty, people have designed various antitheft blade locking heads, and the blade locking head with stop locking mechanism namely is wherein a kind of.Blade locking head with stop locking mechanism generally includes lock body, be arranged at the lock core in the lock body movingly rotationally, blade and stop locking mechanism, lock core upper edge axially parallel is arranged also, and vertical and axis is provided with the blade slotted eye, blade is arranged in the blade slotted eye, blade and blade slotted eye are slidingly matched, blade one side is locking edge, locking edge is provided with the groove of unblanking that is made of breach, blade also is provided with the lock tooth, described stop locking mechanism comprises paralleling to the axis and is arranged on the lock core line of rabbet joint vertical with the blade slotted eye and that be communicated with, the locking edge groove that arranges on lock body inwall and the described line of rabbet joint opposite position, the groove of unblanking that is arranged on the blade locking edge reaches and a tablet lock lock lock composition that can slide in the passage of the described line of rabbet joint and the formation of locking edge groove, the locking stop is inboard to match with the blade groove of unblanking, the locking stop outside matches with the locking edge groove, when blade lock locking, the both sides of locking stop lay respectively in the locking edge groove of lock core and lock body, unblank groove not point-blank on the lock core on all blade, the blade side props up the locking stop and makes in its lock core of can not withdrawing, and makes lock core and lock body not to relatively rotate; When unblanking, the lock mutual guide effect of tooth of alveolus by on the key and blade side forces the unblank groove of shift in position on blade of each blade to be in a straight line, at this moment, the inboard of locking stop is slipped in the groove of unblanking on the blade, the locking stop is withdrawn in the lock core from lock body, and lock core can rotate and finish and unblank relative to lock body.Traditional blade locking head with stop locking mechanism recovers to be stuck in the locking edge groove in order to ensure one side of locking stop after extracting key automatically, usually all back-moving spring need be set in lock core, one end of back-moving spring is against on the locking stop, makes the locking stop keep a power that slides to the locking edge groove.This mode causes complex structure, assembling inconvenience, and cost of production is higher.
Summary of the invention
The objective of the invention is to provides a kind of simple in structure, easy to assembly for overcoming above-mentioned the deficiencies in the prior art, the twayblade tapered end that cost of production is lower.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the twayblade tapered end, comprise lock body, be arranged at the lock core in the lock body movingly rotationally, blade and stop locking mechanism, lock core upper edge axially parallel is arranged also, and vertical and axis is provided with the blade slotted eye, blade is arranged in the blade slotted eye, blade one side is locking edge, locking edge is provided with the groove of unblanking that is made of breach, described stop locking mechanism comprises paralleling to the axis and is arranged on the lock core line of rabbet joint vertical with the blade slotted eye and that be communicated with, the locking edge groove that arranges on the lock body inwall, the groove of unblanking that is arranged on the blade locking edge reaches and a tablet lock lock lock composition that can slide in the passage of the described line of rabbet joint and the formation of locking edge groove, the locking stop is inboard to match with the blade groove of unblanking, the locking stop outside matches with the locking edge groove, it is characterized in that: be equipped with a pair of blade in the described blade slotted eye, described a pair of blade is provided with the back-moving spring that promotes to the end separately, the dual-side of the described groove of unblanking becomes to be obliquely installed, the side that described locking stop is relative with the groove of unblanking is provided with the inclined-plane that the dual-side with the groove of unblanking is complementary, the elastic force of described back-moving spring will be enough to make the locking stop to withdraw from the groove of unblanking under the groove of unblanking interacts with locking stop inclined-plane, and direction one side of unblanking of described locking edge groove is the inclined-plane setting.
Owing to be provided with the back-moving spring that promotes to the end separately at described a pair of blade, the dual-side of the described groove of unblanking becomes to be obliquely installed, the side that described locking stop is relative with the groove of unblanking is provided with the inclined-plane that the dual-side with the groove of unblanking is complementary, and the elastic force of described back-moving spring will be enough to make the locking stop to withdraw from the groove of unblanking under the groove of unblanking interacts with locking stop inclined-plane, therefore need not to arrange again the resetting-mechanism of locking stop, the locking stop is under the action of reset spring of blade after extracting key, can recover to be stuck in the locking edge groove automatically on one side, simplified the structure of tapered end, make things convenient for assembling, reduced cost of production.
The invention will be further described below in conjunction with accompanying drawing, provides embodiment simultaneously.
