Abstract
The utility model relates to an interlocking mechanism for opening and closing doors, which is provided with a straight tongue and an inclined tongue. The utility model belongs to the technical field of door locks. The utility model is composed of a lock core shell 1, a straight tongue body 2 which can be slid in a guide hole of the lock core shell 1, a straight tongue shifting block 3 which is rotated a hole on the lock core shell 1, a rotary spacing pin 4 fixed on the lock core shell 1, a positioning plate 5 which is rotated around the rotary spacing pin 4, a restoring spring 6, a safety block 7 which is rotated around a shaft 8, a pressure spring 9 on an inclined tongue body 12, a shifting sleeve 10 of the inclined tongue and a restoring spring 11 of the inclined tongue, wherein, the inclined tongue body which is sheathed in the guide hole of the lock core shell 1 can be slid. The utility model has the advantages of simple structure, convenient operation, firmness, reliability, easy popularization, etc.
Description
Technical field:
The utility model relates to a kind of straight tongue, oblique tongue switch door interlinked mechanism, belongs to the door lock technical field.
Background technology:
The present door lock that uses, general two retainings that divide of its straight tongue are got, complex operation, and insure the restriction that part is subjected to lock core structure, be damaged because of intensity is on the weak side easily.
Summary of the invention:
The utility model is by lock core shell 1, the straight tongue body 2 that can in the pilot hole of lock core shell 1, slide, the straight tongue slide block 3 that rotate in hole on lock core shell 1, be fixed on the rotary spacing pin 4 on the lock core shell 1, around rotating location-plate 5, the back-moving spring 6 that spacer pin 4 rotates, around the safety block 7 that axle 8 rotates, be enclosed within the pilot hole of lock core shell 1 slidably stage clip 9 on the oblique tongue body 12, tiltedly tongue sliding set 10, tiltedly tongue back-moving spring 11 is formed.
Straight tongue of the present utility model is once got and is put in place, and swing locking is adopted in insurance, has simple in structurely, easy to operate, solid and reliable, is easy to advantages such as popularization.
Description of drawings:
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is the oblique tongue interlock figure in the utility model structure.
The specific embodiment:
Implementation of the present utility model is:
As accompanying drawing 1, when external force makes safety block 7 after axle 8 is rotated away from groove on the straight tongue slide block 3, rotate counterclockwise straight tongue slide block 3, make in the straight tongue body 2 indentation lock core shells 1, location-plate 5 is under the effect of back-moving spring 6, press to the locating surface of straight tongue slide block 3, make straight tongue slide block 3 be in metastable position.After the external force on the safety block 7 disappeared, safety block 7 rotated back into automatically in the groove of straight tongue slide block 3 and locks.Make safety block 7 turn-ofves when applying external force once more, rotate counterclockwise straight tongue slide block 3, will drive oblique tongue sliding set 10, stage clip 9, overcome the resistance of oblique tongue back-moving spring 11 and make in the oblique tongue body 12 indentation lock core shells 1, realize the function of opening the door.If safety block 7, is then opened straight tongue body 2 all the time by external force effect turn-off, tiltedly tongue body 12 can carry out continuously.When clockwise rotating straight tongue slide block 3 once more, straight tongue body 2 will be got again.Safety block 7 rotates back in the groove of straight tongue slide block 3 and locks again, promptly finishes the do action of a switch door.
