Abstract
The invention discloses a blade lock, which comprises a lock head and a matched key. The lock head comprises a lock body and a lock core in the lock body, and the lock core is axially provided with a plurality of transversely placed and penetrating blade holes which communicate with an axially arranged key hole; each blade hole is inside provided with a blade, and the same sides of the blades are provided with projections close to the middle of the same sides and extending into the key hole; the lock core is provided with blade return springs corresponding to the blades respectively; the lock body is provided with hole slots corresponding to the blade holes on the lock core, and one ends of the blades extend into the hole slots on the lock body; the key matched with the lock head comprises a key piece, one surface of the key piece is provided with an internal milling gullet, and at least one sidewall of the internal milling gullet is provided with teeth. The lock of the invention is characterized in that the lock head can adopt single surface internal milling gullet key having different structure with common key, increases the difficulty of unlocking, and improves the theftproof performance of the lock.
Description
Technical field
The invention belongs to lockset, be specifically related to a kind of blade lockset.
Background technology
In the existing lockset, a kind of blade locking head is arranged, this tapered end comprises the lock core in lock body, the lock body, lock core is provided with blade, the use that can only match with normal key of blade in this tapered end can not match with the key of mill teeth groove in the single face, is therefore limited to aspect theftproof.
Summary of the invention
The object of the present invention is to provide a kind of can with the supporting blade lockset of milling teeth groove key in the single face, the difference of its structure can increase the difficulty of unblanking, and improves the theftproof performance of lock.
Realize that purpose technical scheme of the present invention is: blade lockset of the present invention comprises tapered end and supporting key thereof; Described tapered end comprises the lock core in the lock body, lock body, and the lock core upper edge is axially arranged with the vane hole of some horizontal perforations, and vane hole communicates with the keyhole of axially setting; Be provided with blade in each vane hole, be provided with the projection that extend in the keyhole near the middle part on the homonymy of each blade, corresponding each blade is provided with the blade return spring respectively on the lock core; With the corresponding hole slot that is provided with of vane hole on the lock core, an end of blade stretches in the hole slot on the lock body on the lock body;
Also comprise and the supporting key of described tapered end, comprise a spoon sheet, mill teeth groove in the one side of spoon sheet is provided with is provided with tartar at least on a sidewall of interior mill teeth groove.
Blade in the described vane hole can be a slice or two.
Characteristics of the present invention are keys that tapered end can use mill teeth groove in the single face different with the normal key structure, and it is few to have overcome existing lock head structure, and the deficiency of long easy crack of time has increased the difficulty of unblanking with this, have improved the theftproof performance of lock.
The invention will be further described below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the schematic diagram of tapered end of the present invention.
Fig. 2 is the right view of Fig. 1.
Fig. 3, Fig. 4 are respectively the different conditions schematic diagrames of Fig. 1, Fig. 2.
Fig. 5, Fig. 6 are the different key schematic diagrames supporting with tapered end of the present invention.
The specific embodiment
See Fig. 1, Fig. 2, tapered end of the present invention comprises the lock core 2 in the lock body 1, lock body 1, and lock core 2 upper edges are axially arranged with the vane hole 10 of some horizontal perforations, and vane hole 10 communicates with the keyhole 6 of axially setting; Be provided with two blades 4,8 that are stacked as a group mutually in each vane hole 10, the homonymy of blade 4,8 is respectively equipped with the projection 5,7 that extend in the keyhole 6 near the middle part, and the corresponding blade of respectively organizing in the blade 4,8 is provided with blade return spring 3,9 relatively respectively on the lock core 2; On the lock body 1 with lock core 2 on the corresponding hole slot 11,12 (referring to Fig. 3) that is respectively equipped with in two ends of vane hole 10, an end of blade 4,8 stretches into respectively in the hole slot 11,12 on the lock body 1.
See Fig. 5 with milling teeth groove key in the supporting single face of tapered end of the present invention, comprise spoon sheet 13, mill teeth groove 14 in the one side of spoon sheet 13 is provided with is provided with tartar on the two side of interior mill teeth groove.
Operating principle
The supporting use of milling teeth groove key in tapered end of the present invention and the single face.See Fig. 3, Fig. 4, after spoon sheet 13 inserts lock core, tartar on the spoon sheet 13 on the two side of mill teeth groove 14 acts on the projection on the different blades in each vane group respectively, force two blades in each vane group in lock core, to do relative motion respectively, the end that blade is positioned at the lock body slotted eye returns to lock core, and at this moment lock core can rotate relative to lock body becomes unlocking condition; After extracting key, the blade in each vane group resets under its return spring effect, and the end of blade is stretched in the slotted eye of lock body, and lock core and lock body are connected as a single entity, and at this moment lock core can not rotate relative to lock body becomes locking states (referring to Fig. 1, Fig. 2).
Tapered end of the present invention also only the same side in each vane hole a slice blade is set, the key supporting with it is provided with tartar on the two side of the interior mill teeth groove of spoon sheet.Only utilize the tartar on the sidewall of mill teeth groove in spoon sheet to cooperate during use with blade.
Also two blades can be set in each vane hole, the key supporting with it is provided with tartar (referring to Fig. 6) on a sidewall of the interior mill teeth groove of spoon sheet.Only utilize the tartar on the interior mill teeth groove sidewall of spoon sheet only to cooperate during use with a slice blade that each is organized in blade.
The purpose of doing like this can increase the disguise of lock head structure, because from being difficult to judge the structure of tapered end in appearance, further strengthen antitheft purpose with this.
Claims (2)
1, a kind of blade lockset, blade lockset comprise tapered end and supporting key thereof, it is characterized in that:
Described tapered end comprises the lock core in the lock body, lock body, and the lock core upper edge is axially arranged with the vane hole of some horizontal perforations, and vane hole communicates with the keyhole of axially setting; Be provided with blade in each vane hole, be provided with the projection that extend in the keyhole near the middle part on the homonymy of each blade, corresponding each blade is provided with the blade return spring respectively on the lock core; With the corresponding hole slot that is provided with of vane hole on the lock core, an end of blade stretches in the hole slot on the lock body on the lock body;
