Abstract

The utility model provides an anti-theft sheet lock and a key. A plurality of sheet grooves are arranged on a lock core and a front sheet and a rear sheet which are superposed with each other back and forth are arranged in each sheet groove. Two sheets share one spring and the spring is arranged in a hole arranged in the middle of the front sheet. The directions of the spring forces applied to two sheets are opposite and the positions of two sheets can be transposed. The key teeth are arranged at two sides of the key body or at two sides of an intermediate groove of the key body or on the side surface of two side grooves. Because a caging pin is adopted for the utility model, the utility model is characterized in that the locking head can be unlocked only when the positions of all the sheets are determined simultaneously, the utility model overcomes the defect that the traditional antitheft marbles of the locking head or sheets are levered one by one, the performances of preventing the skeleton key, the unlocking gun and the technical unlocking are very superior, the key which does not form a complete set can very hardly unlock the lock and the safety performance is superior.

Description

A kind of antitheft page or leaf mortice lock and key

Technical field

The utility model relates to a kind of lockset, especially a kind of antitheft page or leaf mortice lock and key.

Background technology

Common page or leaf mortice lock locks lock core by the page or leaf sheet and rotates, each page film trap is only installed a page or leaf sheet and a spring in the lock core, during locking, the page or leaf sheet that is installed in the lock core makes lock core and lock body relatively rotate in the groove that enters lock body under the effect of spring force, when inserting matched key, key makes a page sheet move away the lock body groove and enters lock core fully, and lock core can rotate relative to lock body.This problem that is latched in is: because mismachining tolerance page or leaf sheet can not block lock body simultaneously, the criminal is easy to one by one the page or leaf sheet be pushed aside with instrument, thus a lock open, also be easy to use master key, Unlocking guns etc. are opened lock.

Summary of the invention

The purpose of this utility model provides a kind of employing locking pin structure, has only when whole page or leaf sheets and reserves the position simultaneously, just can open tapered end, and matched key, the design of page or leaf chip architecture is ingenious, antitheft, safety is good antitheft page or leaf mortice lock and key.

Technical solution adopted in the utility model is:

Have the several sheets groove on lock core, folded mutually preceding page or leaf sheet in two front and back and back page or leaf sheet are housed in each page film trap, in the hole before two shared springs of page or leaf sheet, spring are arranged in the middle of the page or leaf sheet, the suffered spring force direction of two page or leaf sheets is opposite.Page or leaf sheet position, front and back interchangeable.

Key tooth flower is opened both sides in spoon body both sides or spoon body medial launder, perhaps in the side of dual-side groove.Key tooth flower is when spoon body both sides, and there are two or three protruding pin the page or leaf sheet bottom side that tapered end cooperates.During both sides, only there are three protruding pin the page or leaf sheet bottom side that tapered end cooperates to key tooth flower in spoon body medial launder.Key tooth flower is when the side of spoon body dual-side groove, and there are two or three protruding pin the page or leaf sheet bottom side that tapered end cooperates.

The locking pin structure that the utility model adopts, the locking cotter way on the lock core is corresponding with the square groove of lock body inboard, and the inboard of stop pin is under the compressing of page or leaf sheet outer wall, and its outside enters in the lock body square groove, and lock core can not rotate, when inserting matched key.Tartar on the key moves a page sheet, and the  connected in star on the page or leaf sheet all overlaps.Stop pin is under the effect of flat pearl spring, and its  shape inboard is slipped in the  connected in star of each piece page or leaf sheet, and stop pin leaves the lock body square groove and enters lock core, and lock core can rotate, and lock is opened.

Because the utility model adopts stop pin, be characterized in having only page or leaf sheet to reserve the position simultaneously when whole, just can open tapered end, solved the drawback that traditional anti-theft lock end pellet shot from a slingshot or page or leaf sheet are pushed aside one by one, its preventing universal key, the performance of Unlocking gun and technical unlocking is very superior, non-matching key, and an extremely difficult lock is opened.

The specific embodiment

Page or leaf sheet anti-theft lock end comprises lock core 1, lock body 4, flat pearl 6, flat pearl spring 7, stop pin 8, the dead man 10 of unblanking, back page or leaf sheet 12, preceding page or leaf sheet 13, matched key 14, leaf spring 15.This lock is to have several sheets groove 16 on lock core 1, folded mutually preceding page or leaf sheet 13 in two front and back and back page or leaf sheet 12 are housed in each page film trap, two shared springs 15 of page or leaf sheet, in the hole before spring 15 is arranged in the middle of the page or leaf sheet 13, the suffered spring force direction of two page or leaf sheets is opposite, also have locking cotter way 2 on the lock core 1, locking cotter way 2 and page or leaf film trap 16 are connected, be provided with stop pin 8 in the locking cotter way 2, each piece page or leaf sheet all has a  connected in star 11 at the end near locking cotter way 2, the inboard 3 that stop pin 8 is pressed close to page sheet is  shape, the  connected in star 11 on each piece page or leaf sheet and the  shape 3 of stop pin 8 are matched, have square groove 9 on the lock body 4, the corresponding and stop pin 8 of locking cotter way on square groove 9 and the lock core 2 matches, the radial direction of lock body 4 has the flat hole of bead 5, the flat hole of bead 5 is provided with flat pearl 6 peaceful pearl springs 7, and spring force is pressed on the stop pin 8 through flat pearl 6, and rear portion and lock core that the dead man 10 of unblanking is fixed on lock core 1 are connected as a single entity.

When tapered end does not insert matched key 14 and is in closure state,  connected in star 11 on every page or leaf sheet under the effect of leaf spring 15 not point-blank, the outside of at this moment selling rationed marketing 8 enters square groove 9 the insides of lock body, block lock core 1, lock core 1 can't be rotated, tapered end is in closure state, as shown in Figure 6.

When inserting the keyhole 18 of matched key 14 to lock core 1, tartar 17 on the key forces every page or leaf sheet to move, every  connected in star 11 on the page or leaf sheet is coincided, be on the straight line, at this moment stop pin 8 is under the effect of flat pearl spring 7, the  shape of its inboard 3 is slipped in the  connected in star of every page or leaf sheet, makes the alignment of the outside of stop pin 8 and the external cylindrical surface on the lock core 1, and at this moment key 14 can drive lock core 1 and driving dead man turning handle lock is opened.

The utility model key tooth flower has three kinds of structures, the page or leaf sheet profile of its cooperation is slightly variant, a kind of is as shown in Figure 2, key tooth flower 17 is in spoon body both sides, the preceding page or leaf sheet 13 of its cooperation and the profile of back page or leaf sheet 12 have only two protruding pin in the bottom side of page or leaf sheet, and two protruding pin width difference are bigger respectively as shown in Figure 3, Figure 4, if three protruding pin are arranged, wherein there is the interval width of two protruding pin must be less than 3mm.Second kind of structure as shown in Figure 7, the both sides of key tooth flower 17 in the medial launder of spoon body, the profile of the preceding page or leaf sheet 13 of its cooperation and back page or leaf sheet 12 only has three protruding pin respectively as Fig. 9, shown in Figure 10 in the bottom side of page or leaf sheet.The third structure as shown in figure 12, key tooth flower is in the side of spoon body dual-side groove, the preceding page or leaf sheet 13 of its cooperation and the profile of back page or leaf sheet 12 are respectively as Figure 13, shown in Figure 14, there are two or three protruding pin page sheet bottom side that tapered end cooperates.And there is the width difference of two protruding pin bigger.
