Abstract

The utility model discloses a key type dual-control door lock, which is controlled by prestored key cipher and a key. A rotating shaft is installed on the lock body of the key type dual-control door lock, and the rotating shaft is provided with a row of gears; the rotation of the gears is carried out by toggling the key on the lock body; if the key is toggled for one time, the corresponding gear is rotated beyond a tooth, when the gear is rotated to the proper position, a lock core shaft can be rotated, and the key type dual-control door lock can be unlocked. The cipher of the key type dual-control door lock can be changed at any time by users, and the security is strong.

Description

Key type dual-control door lock

The utility model belongs to lock, relates to the two control door locks of a kind of button.

At present, the lock with anti-theft feature is more and more, has more effectively played protective action.Lock as present a kind of tape code, unlocking person has only coding and intrinsic coding identical, lock could be opened, but the coding of this lock is once just can not be changed after fixing by manufacturer, so people use or feel inconvenient, particularly for some Finance Departments, this lock non insurance that just seems.

The purpose of this utility model provides a kind of storage encoding function that has, and can set coding at any time by the designer, has the two control door locks of button of dual control function.

The utility model is achieved in that it has a lock body, and a rotating shaft is arranged on lock body, and toothrow wheel is arranged in the rotating shaft, also has a gear shaft with the gears engaged of rotating shaft on lock body; Right-hand member at gear shaft has a hole with protruding slideway, and a lock core shaft that has groove is arranged in the hole.One row and the corresponding button of gear arranged on lock body, and the button front end has a shifting block.In the lock body front portion two one slide rails are arranged, a back-moving spring is all arranged on the slide rail, on slide rail, have one to try to stop people from fighting each other, try to stop people from fighting each other and dead bolt links together, the left end of trying to stop people from fighting each other is connected with a pulling shaft, and slide-bar can drive to try to stop people from fighting each other and slidably reciprocate on lock body, and a slide block is installed on the pulling shaft; Covered a hole on lock body, a guiding bearing pin passes this hole fixedly on the slide block.Push button during use, the gear driven gear shaft is rotated, whenever press once, corresponding gear rotation is crossed a tooth, and when forwarding the relevant position to, the protruding slideway of gear shaft leaves a chute, lock can be opened with the key rotation lock core axle then.

The advantage of this lock is: have coding key and key double protection functions, have only coding correspondingly with key, lock could be opened, coding can be changed at any time, strong security.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the new A-A sectional view of this practicality;

Fig. 3 is the vertical view after loam cake, shifting block etc. is taken away of the present utility model.

The utility model is achieved in that it has a lock body 19, and a rotating shaft 1 is installed on lock body 19; One toothrow wheel 2 is arranged in the rotating shaft 1.At the gear 2 corresponding buttons 16 that also have on the lock body 3 in a row and the rotating shaft 1, one end of button is connected with a spring 17, the other end of spring 17 is connected with a shifting block 18, on lock body 3, also has a driven shaft 11, be processed with the gear teeth on the driven shaft 11, and by 2 engagements of the wheel of the toothrow in the gear teeth and the rotating shaft 1.A hole is arranged on driven shaft 11, the slideway of projection is arranged in the hole, a lock core shaft 15 is arranged in this hole, fluted protruding slideway with driven shaft 11 is corresponding in the lock core shaft.Be connected with a plectrum 13 at driven shaft 11 front ends.On lock body 3, also be fixed with two one slide rails 10, a back-moving spring 12 is all arranged on the slide rail 10, on slide rail 10, also have one can try to stop people from fighting each other 8, be connected with a dead bolt 9 at the right-hand member of trying to stop people from fighting each other along what slide rail slided.In order to unblank indoor, on the loam cake 3 of lock body, be processed with a bar hole, pulling shaft 7 passes this hole and is fixed on and tries to stop people from fighting each other on 8, is fixed with a slide block 6 on pulling shaft 7, has one to suspend pin 5 on the slide block 6, suspends on the pin 5 to be fixed with a direction turning piece 4.Also have a common lock core 14 on lock body 19, said common lock core 14 can drive lock core shaft and rotate.

During use, press button 16 by giving fixed coding in advance, whenever press once, shifting block 18 makes corresponding gear 2 change a tooth, forward to when giving allocation, gear 2 drives the groove that slideway that driven shafts 11 forward right-hand member hole internal projection just to leaves lock core shaft 15, at this moment inserts key and makes lock core 14 drive lock core shafts to rotate, be installed in plectrum 13 in the lock core shaft and force dead bolt to be tried to stop people from fighting each other 8 to move to left along slide rail, lock is promptly opened.If go out temporarily, can be with slide block 6 pullings, driving tries to stop people from fighting each other moves to left, rotate rotor 4 then, make to suspend and sell fixing in the hole of lock body upper end, at this moment dead bolt can not be withdrawn, reset if will suspend pin, trying to stop people from fighting each other so to make dead bolt stretch under the effect of spring, and door is locked.
