Abstract
The utility model discloses a master-slave door bolt lock comprising an upper bolt rod, a lower bolt rod and a locking device which are all arranged on a door leaf, wherein the locking device comprises a U-shaped plate, a lock cylinder, a steel ball, two driving piles and a shaft sleeve plate, wherein the U-shaped plate is fixed on a door leaf panel; the lock cylinder is fixed in the U-shaped plate; the steel ball is fixed at a brake groove or rotary groove of the lock cylinder through a spring, a pan head screw and a steel ball sleeve; the two driving piles are fixedly connected with the lock cylinder through driving plates; the shaft sleeve plate is connected with two unsealed sides of the U-shaped plate; and one of the driving piles is in active link with the upper bolt rod, and the other one is in active link with the lower bolt rod. By adopting the design that the lock cylinder controls the door leaf to open and close in a one point way through the upper bolt rod and the lower bolt rod, the utility model solves the problems that the door leaf is inconvenient to open and close and the strength of the upper corner and the lower corner of the door leaf is influenced; and in addition, the master-slave door bolt lock is convenient to install and is suitable for various doors and windows.
Description
Technical field
The utility model relates to door, particularly relates to composite door latch lock.
Background technology
Before the utility model proposes, the structure of the upper and lower latch of the general employing of latch lock of biparting and many fan steel doors is controlled the opening and closing of door leaf respectively, but this structure has the following disadvantages:
1, because this structure adopts upper and lower latch to control the opening and closing of door leaf respectively, so the opening and closing inconvenience of door leaf;
2, owing to when upper and lower latch is installed, need open larger-size rectangular opening in the door leaf side, thus the intensity in the upper and lower bight of door leaf decrease, under the effect of impact force, the door leaf easy deformation.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, provides a kind of opening and closing convenient and do not influence the composite door latch lock of door leaf intensity.
In order to realize above purpose, the composite door latch lock that the utility model provides, comprise: be installed in the last bolt rod on the door leaf, following bolt rod and locking device, its feature is being: described locking device comprises the U-shaped plate that is fixed on the door skin, be fixed on the lock core in the U-shaped plate, lock core is fixedly connected with two transmission stakes by driver plate, a transmission stake and last bolt rod active link, another transmission stake and following bolt rod active link, pass through spring, pan head screw and steel ball sleeve are fixed on the detent recess of lock core or the steel ball in the swivelling chute, with the axle sleeve plate that links to each other with the unsealed both sides of U-shaped plate.
In the such scheme, described axle sleeve plate has been provided with the limiting plate of position-limiting action.
The utility model is compared with the prior art, and shows that fully its superiority is:
By adopting the design of upper and lower bolt rod by lock core single-point control door leaf switch, the opening and closing of door leaf are convenient, do not influence the upper and lower bight of door leaf intensity, and easy for installation.
