Description

A kind of blade lock pin and key

Technical field

The present invention relates to lock & key, special other Wataru and blade lock & key.

Background technology

Now popular blade lock on the market, is equipped with two blades in the vane hole of its lock gall, and its theftproof performance is good not enough.

Summary of the invention

The object of the invention is to overcome above-mentioned weak point and a kind of blade lock pin and key are provided.Three blades are housed in its lock gall vane hole, are provided with on the key three groups of tartars, theftproof performance is good.

The present invention adopts following technical scheme.

Blade lock pin and a key, include lock body, lock gall, blade, side column and key, and lock gall is provided with vane hole, and three blades that mate with key tooth flower are housed in each vane hole, comprises front vane, Leaf, rear blade.

Lock gall is provided with three or four or five vane holes.

Lock gall is provided with six or seven or eight vane holes.

The front end of lock gall keyhole is provided with inclined-plane.

Blade is thin plate sheet shape, and its top is provided with V-notch, is provided with below protrusion sheet.

Key is provided with three groups of variform tartars, comprises left tartar, right tartar and middle tartar, and middle tartar is snakelike tank.

The invention has the advantages that: due to three blades being housed in lock gall vane hole of the present invention, be provided with on the key three groups of tartars, the front end of lock gall keyhole is provided with inclined-plane, and compared with the prior art, theftproof performance is good.Imbody is as follows.

1, overlap not open, have on the key three groups of independently tartars, teeth form shape is ever-changing, and the shape of key is also different with the key of existing lockset, can prevent that lawless person from opening lock core of the present invention with other key cover.

2, dial not open, three blades are housed in each vane hole on lock gall, lateral clearance between blade projection is less, when inserting unlocking tool and stir in lock gall certain sheet blade, also another sheet or another several blades have been driven, the position that method that prior art unblanks can not all be pushed out all blades simultaneously, makes prior art method for unlocking can not open lock core of the present invention.

3, pull not open, fill after blade in lock gall, the remaining space in lock gall keyhole is very little, can only insert the tool that goes into operation by force that a slice is very thin, and when firmly twisting goes into operation by force tool, instrument is twisted off, so use the tool that goes into operation by force can not pull open lock core of the present invention.

4, prize not open, lock gall keyhole front end is processed into inclined-plane, makes picklock can not find effective fulcrum, can not pry open lock core of the present invention.

5, bore not open, in lock gall, outer blade is anti-drilling hard metal sheet, and the side column of a side adopts anti-drilling material to make outdoors, makes the method for boring lock with electric drill can not open lock core of the present invention.

The specific embodiment

The present invention is further illustrated with accompanying drawing in conjunction with the embodiments.

Referring to accompanying drawing, blade lock pin and a key, include lock body, lock gall, blade, side column and key, and lock gall 16 is provided with vane hole, three blades that mate with key tooth flower are housed in each vane hole, comprise front vane 15-1, Leaf 15-2, rear blade 15-3.

On lock gall, can establish a plurality of vane holes, the present embodiment is five, and other embodiment is respectively three, four, six, seven, eight.

Referring to Fig. 1, the front end of lock gall keyhole is provided with inclined-plane 10.

Referring to Fig. 8 to Figure 13, blade is thin plate sheet shape, and its top is provided with V-notch, is provided with below protrusion sheet.The structure of blade, shape can have multiple, and its top V-notch center line is different with the distance of protruding below sheet inner edge.The present embodiment has six kinds of blades, is respectively blade A, B, C, D, E, F.

Referring to Fig. 4, Fig. 5, key 17 is provided with three groups of variform tartars, comprises left tartar 171, middle tartar 172 and right tartar 173, and middle tartar is snakelike tank, and left tartar, right tartar are outer milling tooth.

Referring to Fig. 1, Fig. 1 is lock body 1, lock gall 16, blade, leaf spring 14, side column 5, sealing bead 2, spring 3, push away the assembling drawing of the component such as post 11, slide block 12, collar 13, two lock galls are housed in lock body, the inner side of door, outside are each, door in, all can open the lock with the key outdoors, the assembly relation of each component is same as the prior art, just in lock gall vane hole, three blades is housed, and is embodiments of the invention.During assembling blade, first there is ready-made key, then select the blade matching to pack in vane hole according to tartar on the key.

In Fig. 2, lock gall hole 103 is through hole.

Sketch of the present invention unblanking and locking.

1, unblank, key inserts from the keyhole of lock gall, blade is driven enable possition by key tooth flower, at this moment, the V-notch all align on all blades and the middle in lock gall, side column is owing to being subject to the thrust of side column spring, its edge of a knife falls in blade V-notch, side column all returns in lock gall, and at this moment lock gall can rotate and drive thumb wheel to the direction rotation of unblanking by slide block, completes the action of unblanking.

2, locking, insert the key of this lock core, drive thumb wheel to the contrary direction rotation of unblanking, lock pearl tip in lock body drops in the small rut of side column upper surface, produce certain rotational resistance, the hand that makes to hold key has a kind of sensation of location, at this moment can outwards pull key, in the process pulling key, the blade in lock gall is under the drive of key tooth flower, and V-notch misplaces, side column jack-up, in side column groove in the upper partial insertion lock body of side column, lock gall can not be rotated, complete the action of locking.
