Abstract

The invention relates to a sheet marble lock head, belonging to the key element of lock, which can solve the problem of present lock which can not prevent thief and produce hard. It is characterized in that: when it is not inserted by key, the lock sheet (4) is clamped in the lock open (18) of lock ring (5) without rotating; when inserting the key, the key bar (12) can push the lock sheet (4) with a concave (14) to position the concave (14) on the lock ring (5), and rotating the key to rotate the lock shaft (2), then the lock can be open or locked. The invention can apply variable mechanical locks.

Description

Sheet-like pin tumbler lock head

Technical field

The present invention relates to a kind of tapered end, especially a kind of sheet-like pin tumbler lock head.

Background technology

The core of lockset is a tapered end, the pellet shot from a slingshot class tapered end that generally uses in the market, and they have following shortcoming:

1, these tapered ends can both in a few minutes, even be opened in a few second with the method for technology unlocking under keyless situation.A kind of tool of exchanging work of drawing that the master key principle unblanks that uses is arranged, on a forked scale copper or steel wire, have can bi-directional movable the elasticity hook.This instrument can be opened multiple on the market at present cylinder lock effectively.General cylinder lock only needs with two steel wires, one sub two laybacks of lock core, give a revolving force, lock core is turned an angle, another root is drawn in the spoon groove, make the pellet shot from a slingshot retaining on the edge of tapered end lock hole, use the principle of master key, can unblank.

2, location and the anti-ditch muscle of the effect of pulling out of drawing have generally been arranged on the key.In fact anti-to draw effect very little for the ditch muscle that matches with key of lock core, because of key need have certain intensity, just certain thickness must be arranged, as long as thickness is arranged, a spoon groove just has width, has the just difficult anti-foreign matter of width to enter to draw group.Because of the comparable key of foreign matter is thinner, the easier variation of shape.And these ditch muscle have restricted the global design of lock and have increased processing cost.

3, the tooth punching method of general key is to go out anodontia key billet, processes by tooth by required tooth number again, and time-consuming like this, cost is higher, and in the prior art, the key of having opened tooth must be strict with tapered end is walked.

When 4, prior art is made key, also cumbersome when in lock core, assembling pellet shot from a slingshot, must conscientiously check the number, work efficiency is low.

In addition, also has the anti-shortcoming such as unload of the outer end structure of mutual opening rate height, tapered end.

Summary of the invention

The purpose of this invention is to provide a kind of sheet-like pin tumbler lock head.

The technical solution adopted for the present invention to solve the technical problems is: when not inserting key, locking plate 4 is stuck in the fore shaft 18 of lock ring 5 and can not rotates; After inserting key, spoon bar 12 promotes to have the locking plate 4 of recess 14, makes the recess 14 of locking plate 4 aim at lock ring 5, and screw key makes lock shaft 2 rotations, thereby reaches the purpose of locking and unblanking.

Key inserts from the outer face of tapered end seat 1 and lock shaft 2, tapered end seat 1 cylindrical space Built-in lock axle 2, insert central post 3 in the centre bore of lock shaft 2, lock ring 5 is installed in the lock ring groove 16 of lock shaft 2 and is fixed on the inner face of lock 1, the interior garden of lock ring 5 have with lock shaft 2 on locking plate groove 15 corresponding fore shafts 18, the fore shaft 18 that locking plate 4 passes lock ring 5 is installed in corresponding a plurality of locking plate grooves 15 of lock shaft 2, the inner the inner with 20 chain 4 of locking plate groove 15 corresponding spring eyes of spring 6 by lock shaft 2, lock housing 7 is sleeved on lock shaft 2 the inners, and is fixed on the inner of lock shaft 2.Spoon body 19 1 ends of key connect handle 9, and the other end has the positioning strip 10 and the spoon bar 12 of section constitution annulus.Tapered end locating slot 13 is arranged on the tapered end seat 1, lock shaft locating slot 17 is arranged on the lock shaft 2.

The invention has the beneficial effects as follows that the chip pellet shot from a slingshot is difficult under the situation that does not have key existing unlocking technique and opens along the lock ring groove move mode of lock shaft.The total length that key spoon bar changes is made as several five equilibriums, each five equilibrium is explained with a numerical value, as establish ten five equilibriums, each five equilibrium is explained with the natural number of 0-9, so every key just can be explained with one group of numerical value, utilizes this group numerical value, also can allot key under the situation of no original key, key is also more or less freely, simple with the assembling of lock in process of production, and mutual opening rate is low.Tapered end of the present invention and lock shaft design are all comparatively firm, can effectively prevent dismounting.

The specific embodiment

By Fig. 1 to Fig. 9 as can be known, tapered end seat 1 is a hollow cylindrical body, circular keyhole 11 is arranged, cylindrical space Built-in lock axle 2, insert central post 3 in the centre bore of lock shaft 2, lock ring 5 is installed in the lock ring groove 16 of lock shaft 2 and is fixed on the inner face of lock 1, the interior garden of lock ring 5 have with lock shaft 2 on locking plate groove 15 corresponding a plurality of fore shafts 18, the fore shaft 18 that locking plate 4 passes lock ring 5 is installed in corresponding a plurality of locking plate grooves 15 of lock shaft 2, the inner the inner with 20 chain 4 of locking plate groove 15 corresponding spring eyes by lock shaft 2 of spring 6.

After dialling bar 8 and being placed in lock shaft 2 bottom centre holes, pass the cylindrical void of dialling of lock housing 7 bottoms.Lock housing 7 is sleeved on lock shaft 2 the inners, and is fixed on the inner face of lock shaft 2, and is also that spring 6 and group bar 8 is fixing simultaneously.Tapered end locating slot 13 is arranged on the tapered end seat 1, lock shaft locating slot 17 is arranged on the lock shaft 2.

Key 19 1 ends connect handle 9, and the other end has the positioning strip 10 and the spoon bar 12 of section constitution annulus.Positioning strip 10 is with the insertion of key, pass the interior locating slot 13 of keyhole 11 after, arrive the lock shaft locating slot of lock shaft 2, for key operated lock provider to locating and moment of torsion.

When not inserting key, locking plate (4) is stuck in the fore shaft (18) of lock ring (5) and can not rotates; After inserting key, spoon bar (12) promotes to have the locking plate (4) of recess (14), makes the recess (14) of locking plate (4) aim at lock ring (5), and screw key makes lock shaft (2) rotation, thereby reaches the purpose of locking and unblanking.

The locking plate of Fig. 2 signal is at recess 14 both sides design jut on one side, to increase the difficulty of technology unlocking.
