Description
Technical field
The present invention relates to a kind of tapered end, particular with the blade locking head of stop locking mechanism.
Background technology
In order to improve the theftproof performance of blade locking head, increasing opening difficulty, people devise various antitheft blade lock head, and the blade locking head with stop locking mechanism is i.e. one therein.There is blade locking head generally includes lock body, dynamic cooperation is rotatablely arranged in lock body lock core, blade and the stop locking mechanism of stop locking mechanism.On lock core, the most arranged in parallel and vertical and axis is provided with blade slotted eye, and blade is arranged in blade slotted eye, and blade is slidably matched with blade slotted eye, and blade side is locking edge, and locking edge is provided with the groove of unblanking being made up of breach, and blade is additionally provided with lock tooth；Described stop locking mechanism include paralleling to the axis be arranged on lock core on the lock core line of rabbet joint that is vertical with blade slotted eye and that connect, lock body inwall and described lock core line of rabbet joint opposite position arrange locking edge groove, be arranged on blade lock deckle unblank groove and with a tablet lock lock lock composition that can slide in the passage that the described lock core line of rabbet joint and locking edge groove are formed, lock recess of unblanking with blade inside stop, match with locking edge groove outside locking stop.When blade lock locking, the both sides of locking stop lay respectively in the locking edge groove of lock core and lock body, on lock core on all of blade unblank groove the most point-blank, blade side prop up locking stop makes it can not retract in lock core so that lock core and lock body can not relatively rotate；When unblanking, the shift in position of each blade is forced until the groove of unblanking on blade is in a straight line by the lock mutual guide effect of tooth of alveolus on the key and blade side, now, manually rotary locking cylinder, stop is along lock body inclined towards lock core line of rabbet joint lower slide, the inner side making locking stop is slipped into and is unblanked in groove on blade, and locking stop is retracted in lock core from lock body, and lock core can rotate relative to lock body and complete to unblank.Traditional blade locking head with stop locking mechanism can automatically disengage locking edge groove in order to ensure the outer side edges locking stop after the key that comes in and goes out and open smoothly, typically each need to be respectively provided with coupled logical back-moving spring storage chamber at the two ends of the lock core upper lock core line of rabbet joint, back-moving spring storage arranges back-moving spring in chamber, the position that locking stop is corresponding with back-moving spring storage chamber near the two ends of groove side of unblanking is provided with projection, back-moving spring is placed in back-moving spring storage Zhong Hou one end, chamber and is against on the projection of locking stop, the other end is closed in back-moving spring storage chamber and makes locking stop keep the power of the groove that slides to unblank.Closing in order to back-moving spring is store the opening in chamber, existing way is all to process a dovetail groove in the position of the opening in lock core upper reset spring storage chamber, flattens the opening closing that back-moving spring is store chamber after then inserting a piece of copper sheet in dovetail groove.This mode causes structure complicated, and processing difficulties assembles inconvenience, thus production cost is higher, and efficiency is low.nullIn order to overcome the defect of above-mentioned existing blade locking head，Application No. 201310126438.X，Filing date on April 11st, 2013、Entitled " a kind of double-vane tapered end " discloses a kind of double-vane tapered end，This double-vane tapered end includes lock body、Dynamic cooperation is rotatablely arranged at the lock core in lock body、Blade and stop locking mechanism，On lock core, the most arranged in parallel and vertical and axis is provided with blade slotted eye，Blade is arranged in blade slotted eye，Blade side is locking edge，Locking edge is provided with the groove of unblanking being made up of breach,Described stop locking mechanism includes paralleling to the axis and is arranged on lock core the lock core line of rabbet joint that is vertical with blade slotted eye and that connect、The locking edge groove arranged on lock body inwall、Be arranged on blade lock deckle unblank groove and with a tablet lock lock lock composition that can slide in the passage that the described lock core line of rabbet joint and locking edge groove are formed，Lock recess of unblanking inside stop with blade，Match with locking edge groove outside locking stop，Described blade slotted eye is equipped with a pair blade，The pair of blade is each provided with the back-moving spring promoted to end，The dual-side of described groove of unblanking becomes to be obliquely installed，The inclined-plane that the side that described locking stop is relative with groove of unblanking is provided with and the dual-side of groove of unblanking matches，The elastic force of described back-moving spring be enough to make locking stop exit groove of unblanking under groove of unblanking interacts with locking stop inclined-plane，The side, direction of unblanking of described locking edge groove is that inclined-plane is arranged.This tapered end, due to the resetting-mechanism without locking stop, therefore avoids operations such as processing a dovetail groove, simplifies the structure of tapered end, facilitate assembling, reduce production cost.But, owing to the dual-side of groove of unblanking is that inclined-plane is arranged, causing tapered end precision step-down, mutual opening rate becomes big, the most still imperfection.
Summary of the invention
It is an object of the invention to as overcoming existing tapered end precision step-down, mutual opening rate becomes big deficiency, it is provided that one both simple in construction, easy to assembly, and precision is high again, the double-vane tapered end that mutual opening rate is low.
nullIn order to solve above-mentioned technical problem，The present invention adopts the following technical scheme that a kind of blade locking head with stop locking mechanism，Including lock body、Dynamic cooperation is rotatablely arranged at the lock core in lock body、Blade and stop locking mechanism，On lock core, the most arranged in parallel and vertical and axis is provided with blade slotted eye，Blade is arranged in blade slotted eye，Blade side is locking edge，Locking edge is provided with the groove of unblanking being made up of breach,Described stop locking mechanism includes paralleling to the axis and is arranged on lock core the lock core line of rabbet joint that is vertical with blade slotted eye and that connect、The locking edge groove arranged on lock body inwall、Be arranged on blade lock deckle unblank groove and with a tablet lock lock lock composition that can slide in the passage that the described lock core line of rabbet joint and locking edge groove are formed，Lock recess of unblanking inside stop with blade，Match with locking edge groove outside locking stop，It is characterized in that: described in unblank groove both sides with locking stop two sides be arranged in parallel，Described lock core is provided with the resetting-mechanism promoted by locking stop to locking edge groove，The side, direction of unblanking of described locking stop is that inclined-plane is arranged，The side, inclined-plane of described locking edge groove and described locking stop relative to limit also become to be obliquely installed.
Owing to the both sides of groove of unblanking of this tapered end be arranged in parallel with the two sides of locking stop, unblank groove width can substantially with locking stop thickness equal, locking stop can only move up and down in groove of unblanking, and can not swing, so, under same dimensional conditions, the tartar of key is differential can be made more, encoding also the most more, therefore mutual opening rate is low；Simultaneously without back-moving spring being store the opening closing in chamber, the most do not increase the complexity of lock head structure.
