Description

A kind of blade lockset

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 the outer mill teeth groove of 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 outer supporting blade lockset of milling teeth groove key of 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, 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; 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;

Described and the supporting key case spatula sheet of tapered end, 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.

Characteristics of the present invention are keys that tapered end can use the outer mill teeth groove of 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.

Fig. 5, Fig. 6 are the different key schematic diagrames supporting with tapered end of the present invention.

The specific embodiment

Embodiment 1

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, relative end on blade 4,8 the same sides is respectively equipped with the projection 7,5 that extend in the keyhole 8, 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; The corresponding hole slot 11,12 (referring to Fig. 3) that is respectively equipped with the two ends in lock core 2 blade holes 10 on the lock body 1, an end of blade 4,8 stretch into respectively in the hole slot 11,12 on the lock body 1.

See Fig. 5 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, 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, 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).

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. 6) 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.

Claims (2)

1, a kind of blade lockset comprises 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, 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; 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;

Described and the supporting key case spatula sheet of tapered end, 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.

2, blade lockset according to claim 1 is characterized in that blade in the described vane hole is a slice or two.
