Abstract

The invention discloses an improved vane lock, comprising a lock head and a matching key. The lock head comprises a lock body; a plurality of vanes are axially arranged on a lock core in the lock body; the ends of the vanes, at the same side, extend into a projection inside the hole of the key; slots corresponding to the vanes on the lock core are arranged on the lock body; one end of each vane extends into the slots; and communicated spiral grooves are arranged on the lock body; projecting parts matched with the spiral grooves on the lock body are arranged on the lock core. The key comprises a key plate; and external milled gullets are arranged in the lateral part on one side of the key plate and the at least one external milled gullet is patterned with teeth. When the lock core in the lock head rotates, the lock core moves axially relative to the lock body at the same time and can control a lock bolt in the axial direction; therefore the improved vane lock is applicable to the locks in such occasions. The lock head can be matched with a key with only one face provided with external milled gullets, which is different in structure with common keys, thereby, increasing the difficulty in unlocking the lock and improving the performance of burglary prevention.

Description

A kind of improved blade lockset

Technical field

The invention belongs to lockset, be specifically related to a kind of improved 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 lock can not match with the key of the outer mill teeth groove of single face, is therefore limited to aspect theftproof.In addition, lock core has only rotating on the circumference relative to lock body under unlocking condition, will lock unlatching by the sword iron and the dead bolt interlock that are fixed on the lock core afterbody.This tapered end can not be used for along the lockset of lock core shaft's line traffic control dead bolt.

Summary of the invention

The object of the present invention is to provide a kind of can be supporting with the outer milling teeth groove key of single face, the difficulty so that increase is unblanked improves the theftproof performance of lock, and can be along the improved blade lockset of lock core shaft's line traffic control dead bolt.

Realize that purpose technical scheme of the present invention is: the improved 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, the end on each blade homonymy is provided with the projection that extend in the keyhole, and corresponding each blade is provided with the blade return spring respectively on the lock core, and the lock core afterbody is provided with locking bar; 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; On lock body, be provided with the helicla flute of perforation, be provided with the projecting part that matches with helicla flute on the lock body on the lock core;

Also comprise and the supporting key of described tapered end, comprise a spoon sheet, mill teeth groove outside a sidepiece of spoon sheet is provided with is provided with tartar on the sidewall of mill teeth groove at least outside one.

Blade in the described vane hole can be a slice or two.

The present invention is because lock core is provided with the projecting part that matches with helicla flute on the lock body, when inserting key unlocking, projecting part in the process of rotational lock core on the lock core will move by helicla flute on lock body, make lock core when lock body is made circular motion relatively, also do axially-movable, only need the backward rotation lock core during locking.Tapered end of the present invention is exactly to utilize this axially-movable of lock core to reach from the purpose of axial control dead bolt, therefore can be used for the lockset of this occasion.In addition, tapered end can use the key of the outer mill teeth groove of the single face different with the normal key structure, therefore can increase the difficulty of unblanking, and improves the theftproof performance of lock.

The invention will be further described below in conjunction with accompanying drawing.

The specific embodiment

Embodiment 1

See Fig. 1, Fig. 2, Fig. 5, 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, relative end on

blade

4,8 the same sides is respectively equipped with the projection 7,5 that extend in the keyhole 6, 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, and lock core 2 afterbodys are provided with locking bar 17; On the lock body 1 with lock core 2 on the corresponding hole slot 11,12 (referring to Fig. 4) 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; On lock body 1, be provided with the helicla flute 16 of perforation, be provided with the pin 15 that matches with helicla flute 16 on the lock body on the lock core 2.

See Fig. 7 with the outer milling teeth groove key of single face that tapered end of the present invention is supporting, comprise spoon sheet 13, mill teeth groove 14 outside the dual-side of spoon sheet 13 one sides is provided with, the sidewall of mill teeth groove 14 is provided with tartar outside.

Operating principle

The outer supporting use of milling teeth groove key of tapered end of the present invention and single face.See Fig. 3, Fig. 4, Fig. 5, after spoon sheet 13 inserts lock core, tartar outside spoon sheet 13 both sides on the sidewall 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, at this moment lock core can rotate relative to lock body becomes unlocking condition, as spoon sheet 13 (referring to Fig. 6) during rotational lock core 2 in the direction of arrows, helicla flute 16 motions of pin 15 on the lock core 2 on lock body, make lock core 2 move right along axis simultaneously, the locking bar 17 that is located at control dead bolt on the lock core 2 returns in the lock body, when locking, with key backward rotation lock core, making locking bar 17 reach lock body outward can be spacing with dead bolt; 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).

Embodiment 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 outer mill teeth groove sidewall of spoon sheet both sides.Only utilize the tartar on the sidewall of an outer mill teeth groove on spoon sheet to cooperate during use with blade.

Also two blades can be set in each vane hole, be provided with tartar (referring to Fig. 8) on the sidewall of the key supporting mill teeth groove outside of spoon sheet with it.Only utilize on spoon sheet tartar on the outer mill teeth groove sidewall to cooperate during use with a slice blade in each group 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.
