Description

Card-controlled lock cylinder structure

The utility model relates to a kind of improvement of lock plate type lock core structure, belongs to the lockset scope.

Lock plate type lock core structure such as Fig. 1 commonly used at present, Fig. 2, shown in Figure 3, this core is mainly formed by being inserted in lock barrel sleeve 3 after lock barrel bolt 1,2 combinations of lock board.Axially dig on the core hitching post 1 and be provided with a lockhole 11, lockhole 11 sidewall is on one side established a location raised line 12, and on this lock barrel bolt 1, radially wear some film perforations 13 for 2 insertions of lock board, film perforation 13 1 lateral edges dig establishes a hole 14 inserting a spring 15, and lock board 2 one sides are extended a compressing tablet 21 and pressed mutually with spring 15 and touch.Under spring 15 effect, lock board 2 is in the state that backed down when flat, and its top 22 is stretched and placed lock barrel sleeve 3 inner surface correspondences to dig in the alcove of establishing 31, rotates freely in lock barrel sleeve 3 and is locking states with a card shelves lock barrel bolt 1.Be equipped with a rectangle window 23 over against lockhole 11 in the middle of the lock board 2, and have nothing in common with each other the high end of the bottom margin of different windows 23.Groove 41 fit positioning convex strips 12 on key 4 also insert lockhole 11, and the chevron tip edge 42 identical lock board 2 window root edges on the key 4 force in the film perforation 13 of respectively locking board top 22 retraction core hitching posts 1, and releasing is rotated the block at interface and unblanked.

The core of this structure is owing to only rely on the high end of lock board window root edge to decide cooperating of lock and key, both too simple, the lockset group number that permutation and combination is become is limited, and the rectangle window edge on the lock board is smooth, touches sled and dials and pried open for the unprincipled fellow utilizes steel wire or steel disc to stretch into to press easily.

The utility model system forms at above-mentioned defective design improvement, be characterized in that key piece is flatly to insert core, offer several depressions on the one side that area is bigger on the key, extend a splinter at lock board window edge and the corresponding position of depression in addition, by the identical purpose of unblanking that reaches of this depression and splinter.Because its position of depression and the depth offered on the key plane all can have multiple variation, thereby change than the high end that only relies on the chevron tip edge much more permutation and combination is arranged, the repeatability of lockset is reduced.In addition, be provided with one at the lockhole mouth and push plate body, at ordinary times with the lockhole sealing, but key then can insert lockhole easily.Be provided with this and push plate body and be provided with the splinter that differs at the high end at lock board window edge, the thief should lock then very difficult with steel disc or the pirate of the open of steel wire desire, had improved safety, the reliability of lockset.

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 4, padlock is made up of lock body 1 and locking bar 2, and core 3 penetrates from lock body 1 bottom center and places in the lock body 1, and the action of open and close lock is delivered to other devices in the lock body via driving piece 34.

Referring to Fig. 5, Fig. 6, lock core structure is mainly by key 6, and lock tube 30 and sleeve 33 are formed.Lock tube 30 1 end faces are provided with a lockhole 32, and these lockhole 32 ends are provided with positioning convex point 320.Radially being equipped with several lock board holes 31 on the lock tube 30 inserts for locking board 4, the upper and lower position of this lock board 4 respectively is provided with a lug 40, its middle part wears a window 41, the edge of window 41 is provided with a splinter 42 and a spring set cave 43, each lock splinter 42 on the board 4 the position, the height different, after spring 5 is inserted this set cave 43, insert in the lock board holes 31 and be set up near the central lockhole 32 the projection with lock board 4.The inner surface of sleeve 33 is provided with the lug 40 embedding fastenings of groove 330 for lock board 4.In lockhole 32 entrance one plate body 70 is set in addition and matches, lockhole 32 is sealed at spring 7 effect lower bodies 70 with a spring 7.

Key 6 is provided with some depressions 61, its position, the depth is corresponding with each lock splinter 42 on board, in addition with lockhole 32 on positioning convex point 320 opposite positions, offer a chase 60.

Referring to Fig. 7, Fig. 8, when key 6 inserts, drive plate body 70 pushing springs 7, lockhole 32 is opened.The splinter 42 of depression 61 pushing tows on key 6 surfaces lock board 4 and pressuring spring 5, the lug 40 that lock board 4 is located up and down breaks away from the groove 330 and retraction lock board hole 31 of sleeves 33, can make lock tube 30 be rotated, and reaches the purpose of unblanking.

Claims (3)

1, a kind of card-controlled type lock core structure is made up of key 6, lock tube 30, lock board 4 and sleeve 33, it is characterized in that:
