Abstract
The utility model relates to a movable lock button with ciphers, which is composed of a V-shaped lock button and the cipher drive mechanism of a tongue locking baffle board. The drive mechanism comprises a shell body, the tongue locking baffle board, a plug, a plug control rod and a plurality of cipher bars. The cipher bars are moved in a groove on the plug control rod. The round rod of the tail part of the plug control rod is penetrated through a barrel block, is sheathed with a pressure reed and is connected with a pull rope. The lower end of the plug is provided with a chute. An upper part is penetrated through a sheath ring which is fixed to the baffle board and is connected with the baffle board through an elastic rope. The tongue locking baffle board is connected with the inner wall of the shell body through a tension spring. The utility model has the advantages of convenient operation, superior performance, etc. If a key is lost, a door can be opened easily under the condition that a door lock or the door is not damaged.
Description
The utility model relates to field of lockset, particularly a kind of movable snap close with password.
The snap close of existing door lock all is fixed, mainly relies on dead bolt to extend in the snap close and locks a door.If people have lost the key of door lock, just need to destroy door lock or door, just can enter the room, make troubles with regard to the life of giving people like this.
The purpose of this utility model provides a kind of movable snap close with password, to solve after people lose key, can only destroy the problem that door lock or Men Caineng enter the room.
The technical solution of the utility model is achieved like this: a kind of movable snap close with password, password driving mechanism by V-arrangement snap close and dead bolt baffle plate is formed, and the password driving mechanism that it is characterized in that the dead bolt baffle plate is by housing and be located at dead bolt baffle plate in the housing, latch, latch control lever, be made up of the password lattice of the different breach in position on several its; The front end of latch control lever has the inclined-plane, and tail end is a round bar, and the centre has many grooves, and code-bar moves in groove; Be with stage clip on the round bar, and pass the block that is fixed in the housing, its tail end is connected with stay cord; The lower end of latch has chute, and the collar that is fixed on the baffle plate is passed in the upper end, and stretch cord is connected between latch and the baffle plate, and the dead bolt baffle plate can move in the space between baffle plate and the housing sidewall, and can extend in the V-arrangement snap close; Its tail end links to each other with inner walls by extension spring, is fixed on handle on the dead bolt baffle plate and passes hole on the housing sidewall; Be connected with the pull bar of band scale at the tail end of code-bar.
The utility model is installed in door cashier's office in a shop, and the dead bolt baffle plate extend in the V-arrangement snap close, and when locking a door, dead bolt extend in the space of dead bolt baffle plate and V-arrangement snap close formation.If people have lost key, only need according to predefined password, advance or pull out the pull bar of band scale, make the breach of code-bar all aim at groove on the mortise lock control lever, at this moment, the latch control lever is under the effect of stage clip, move right, inclined-plane on it pierces in the chute of mortise lock lower end, and latch is moved down, stretch cord tension simultaneously; When the dead bolt baffle plate loses the barrier effect of latch, rely on the effect of extension spring, the dead bolt baffle plate is moved right, withdraw from the V-arrangement snap close, because dead bolt does not have stopping of dead bolt baffle plate, people just can open door easily.During if will lock a door, by the handle on the dead bolt baffle plate dead bolt baffle plate is moved left with hand earlier, insert in the V-arrangement snap close, and then pulling stay cord, the latch control lever is moved to the left, and at this moment the inclined-plane on the latch control lever breaks away from the chute of latch lower end, and latch is under the effect of stretch cord, move up, to stop dead bolt baffle plate return, careless again push type is pulled out the pull bar of band scale, and breach and the dislocation of the groove on the latch control lever on the code-bar are got final product, band just can be locked a door to the doorstep easily then.Therefore, the utility model compared with prior art has advantages such as easy to use, superior performance, as has lost key, need not to destroy door lock or door again, also can very like a cork door be opened.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of mortise lock control lever;
Fig. 3 is the structural representation of code-bar limited post;
Fig. 4 is the structural representation of code-bar;
Fig. 5 is the structural representation of latch.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
A kind of movable snap close of describing in the accompanying drawing with password, password driving mechanism by V-arrangement snap close (2) and dead bolt baffle plate (3) is formed, the password driving mechanism of dead bolt baffle plate (3) is by housing (13) and be located at the interior dead bolt baffle plate (3) of housing (13), latch (6), latch control lever (23), 8 code-bars (15) which is provided with the different breach in position (30) are formed, the front end of latch control lever (23) has inclined-plane (26), tail end has round bar (17), the centre has (last four of 8 grooves (28), following four), code-bar (15) moves in groove (28), the stability of code-bar (15) motion is that the handy code-bar limited post (14) that is provided with dividing plate (24) between the code-bar (15) and has chute (29) that is located at is controlled, and code-bar limited post (14) is by briquetting (12), (16) be fixed in the housing (13); Be with stage clip (18) on the round bar (17) of latch control lever (23) tail end, and pass the block (19) that is fixed in the housing (13), tail end at round bar (17) is connected with stay cord (21), stay cord (21) is walked around pulley (20) and is stretched out outside the housing (13), pulley (20) is fixed in the housing (13) by pulley bracket (22), the lower end of latch (6) has chute (31), the collar (7) that is fixed on the baffle plate (4) is passed in the upper end, stretch cord (10) is connected between latch (6) and the baffle plate (4), in order to guarantee the balance of mortise lock (6) operation, latch (6) is moved between baffle plate (27) and briquetting (12); Dead bolt baffle plate (3) can move in the space between baffle plate (4) and housing (13) sidewall, and can extend in the V-arrangement snap close (2), the tail end of dead bolt baffle plate (3) links to each other with housing (13) inwall by also spring (8), is fixed on handle (5) on the dead bolt baffle plate (3) and passes hole (9) on housing (13) sidewall; In order to limit the return distance of dead bolt baffle plate (3), in housing (13), be provided with limited block (11); Conveniently reach accurately in order to advance or pull out code-bar (15), be connected with the pull bar (25) of band scale at the tail end of code-bar (15); When using the utility model, dead bolt (1) can extend in the space of dead bolt baffle plate (3) and V-arrangement snap close (2) formation.
