Abstract

The utility model discloses a plug sheet lock. The plug sheet lock comprises a lock body which is arranged on the outer portion, a core body which is arranged on the middle portion, plug sheets, springs, a key and the like, wherein two or more than two circumferential grooves are formed in the inner wall of the lock body, one or more than one axial groove is formed in the inner wall of the lock body, one or more axial lock holes are formed inside the core body, open slots which are communicated with the axial grooves of the lock body are formed in the core body, two or more than two plug sheets are arranged in the lock holes in a stacked mode, the tail portion of each plug sheet is inserted in one open slot and one axial groove of the lock body, the compression springs are arranged between the plug sheets and the bottoms of the lock holes, a through hole is formed in the head portion of each plug sheet, the sizes of the diameters of the through holes of all the plug sheets are different, the plug sheet with a smallest diameter is arranged on the inner side, the plug sheet with a biggest diameter is arranged on the outer side, and the key is a taper rod with a small front end and a big rear end, and steps are arranged on the taper rod. When the key is inserted into the lock to open the lock, the front end of the taper rod penetrates through holes of the plug sheets, the steps abut against ports from the tail portions of the plug sheets to the circumferential grooves, and the lock can be opened with the key being turned.

Description

The patch lock

Technical field

The utility model relates to lock and key, is a kind of with rotating key operated mechanical lock.

Background technology

The common spring lock is eliminated just gradually easily by technical opening.Occurred some in recent years and be difficult for by the cylinder lock of technical opening, but complex structure, the market price is higher.When the key of cylinder lock inserts or extracts, crown and the fretting wear of pellet shot from a slingshot front end,

Handy not as new key when causing old key unlocking.

Summary of the invention

The utility model provide a kind of simple in structure, cost is lower, be difficult for by technical opening, the novel mechanical of fretting wear seldom.

Adopt following technical proposals: a kind of patch lock comprises the lock body of outside, middle core body, spring and key.

The inwall of lock body is provided with two or more circumferential groove, also is provided with one or axial notch that one or more is corresponding with the core body lockhole.

Be provided with one or more axial lockhole in the core body, also be provided with the open slot that lockhole communicates with the lock body axial notch.In each lockhole, stacked one group of patch is installed, every group of patch has two or more than two; The head of patch is installed in the lockhole, and its external diameter is less than more than the 0.01mm of lockhole aperture; The afterbody of patch passes in the axial notch that the core body open slot stretches into lock body, more than the width 0.01mm of its width less than core body open slot and lock body axial notch; The head of patch can have multiple thickness, the convenient selection during for the preparation key, and the thickness of patch afterbody should be more than the width 0.01mm less than corresponding lock body inwall circumferential groove.

What arrange in the core body that a lockhole installs one group of patch is single core lock, two lockholes are set locking for twin-core of two groups of patches is installed, and three cores lock, four-core lock etc.

The head of patch is provided with through hole, the through-hole aperture of each patch differs in size, and the patch of aperture minimum is installed in the inside, presses the pore size order then and installs, the patch of aperture maximum is installed in the outside near the core body cover plate, and an innermost patch can not arrange through hole.

Between patch and the patch and between at the bottom of patch and the lockhole compression spring is installed all.Spring between at the bottom of patch and the lockhole is thicker than the spring steel wire between patch and the patch, and tension force is bigger.

Described key is awl bar or the Taper Pipe that front end is little, the rear end is big, and awl bar or Taper Pipe are provided with one or more step, and the number of steps of operated by rotary motion is lacked one than patch is total.When inserting key unlocking, the front end of key compresses the patch that is installed in an innermost atresia, and step on the key compresses remaining patch.

The beneficial effects of the utility model are: 1. the patch lock construction is simple, dependable performance.2. processing and manufacturing easily, cost is lower.3. different fully with billiards lock structure, be difficult to open with cylinder lock " jinx " masking foil one class tool technique.4. key does not have fretting wear, and old key unlocking is equally handy with new key.

Among the figure: key 1, lock body 2, circumferential groove 3, core body 4, finer wire spring 5, thicker wire spring 6, plug 7, patch 8, core body open slot 9, lock body axial notch 10, core body cover plate 11, lock body lid groove 12, core body lid groove 13, through hole 14, locating flange 15, core body lockhole 16.

The specific embodiment

Illustrated in figures 1 and 2 for single core patch lock of five patches is installed, the inwall of lock body 2 is provided with five circumferential groove 3.

It is shown in Figure 1: when insertion key 1 is unblanked, locating flange 15 on the key 1 also inserts in the lock body lid groove 12 simultaneously, the microcephaly of key 1 passes the through hole 14 of four patches, and its front end compresses and is installed in an innermost atresia patch, and four steps on the key 1 compress all the other four patches.When firmly key 1 inwardly being pushed when putting in place, finer wire spring 5 and thicker wire spring 6 are compressed, five patches are all promoted to put in place in core body lockhole 16 by force, the afterbody of patch 8 is pushed to the port of corresponding lock body circumferential groove 3 simultaneously in core body open slot 9 and lock body axial notch 10, the locating flange 15 on the key 1 also enters in the core body lid groove 13 by lock body lid groove 12.At this moment rotate key 1, the afterbody of patch 8 enters in the corresponding lock body circumferential groove 3 separately, and core body 4, patch 8 rotate with key 1, and the patch lock is unlocked.At this moment because rotated an angle, locating flange 15 is blocked by the lock body lid key 1 with core body 4, and key 1 can not be extracted.

Backward rotation key 1, locating flange 15 turns back to the port that lock body covers groove 12 with core body lid groove 13, and key 1 can be extracted.As shown in Figure 2, at this moment patch 8 and all repositions of core body 4, the afterbody of patch 8 is deviate from lock body inwall circumferential groove 3, enter in the lock body axial notch 10, spring 5, spring 6 upheld, because of the tension force of thicker wire spring 6 bigger, five patches are all pushed away toward the direction of core body cover plate 11, the afterbody door bolt of patch 8 is inserted in core body open slot 9 and the lock body axial notch 10, and core body 4 can not rotate, and the patch lock is locking.
