Abstract
The utility model provides a theftproof page or leaf lock and key, the structure is taken to open on the lock core has a plurality of page or leaf groove, and the preceding page or leaf piece that folds mutually and back page or leaf piece around every page or leaf inslot is equipped with two, a spring of two page or leaf piece sharings, and in the hole of spring setting in the middle of the preceding page or leaf piece, the spring force opposite direction that two page or leaf pieces received. The front and back sheets can be exchanged. The key teeth are arranged on two sides of the key body or two sides of the middle groove of the key body, or on the side surfaces of the grooves on two sides. Because the utility model discloses a stop pin, its characteristics are only when whole page or leaf piece fixed position simultaneously, could open the tapered end, have solved the drawback that traditional theftproof tapered end pellet shot from a slingshot or page piece were dialled one by one, and it prevents the universal key, and the performance of unlocking rifle and technical opening is very superior, and non-supporting key is extremely difficult to open the lock. The safety performance is superior.
Description
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.
