Example 1

As shown in fig. 1 and 2, a lock tongue box comprises a box body 1 and a box body cover 2, the box body cover 2 and the box body 1 are sequentially arranged in front of and at the back of a door frame 3, the two ends of the box body 1 are provided with fixing lugs 4, the fixing lugs 4 are provided with screw holes a5, the two ends of the box body cover 2 are provided with screw holes b6, the door frame 3 is provided with grooves a7, the screw holes a5, the grooves a7 and the screw holes b6 are sequentially penetrated by screws a, the screws a are provided with nuts a, the nuts a and the screws a are matched to clamp the box body 1 and the box body cover 2 and are arranged on the door frame 3.

The working process and principle of the invention are as follows:

when the installation lock, install the lock body on the door earlier, will place box body 1 and box body lid 2 in proper order again in door frame 3 front and back corresponding position, pass screw rod hole a5 and recess a7 in proper order with screw rod an again and be connected with nut a, screw up nut a again, make box body 1 and box body lid 2 install on door frame 3, the debugging of switch door again, see whether the spring bolt can smoothly enter into lock tongue mouth 11 smoothly, if can not just unscrew nut a, finely tune whole lock tongue box again, make the spring bolt can flow the smooth entering into in lock tongue mouth 11. Wherein the box body cover 2 can also function as a door frame guide piece to prevent the door frame 3 therein from causing a wear to the door.

Example 2

On the basis of embodiment 1, as shown in fig. 1, a cavity 8 is provided on the box body 1, a square opening a9 corresponding to the cavity 8 is provided on the cover of the box body 1, two fixing strips a10 are provided in the square opening a9, and the square opening a9 is sequentially divided into a latch opening 11 and two counter-latch openings 12 by the fixing strips a 10. When the door is closed, the lock tongue enters the lock tongue opening 11, and when the lock is locked, the lock tongue is locked reversely and enters the lock tongue opening 12.

Example 3

On the basis of embodiment 1, as shown in fig. 1, the door frame 3 is provided with a square opening b13, two fixing strips b14 are provided in the square opening b13, the position and the size of the fixing strip b14 correspond to those of the fixing strip a10, a groove b15 is provided on the fixing strip b14, a screw hole c16 is provided on the fixing strip a10, the screw hole c16 and the groove b15 are sequentially penetrated by a screw b, a nut b is provided on the screw b, and the nut b is matched with the screw b to tightly cover the box body 1 on the door frame 3.
