[0020] Please refer to Figs. 1-3 This embodiment provides an adjustable lock box, including a lock box body 1, a panel 2, a fixed base 3, a movable base 4, an adjusting base 5, a fixing screw 6, a connecting shaft 7, and a roller 8. The lock box body 1 is a rectangular box with an opening on one side and a hollow interior. The other side of the lock box body 1 opposite the opening is provided with a riveting hole 10 and a bolting post 9. The side wall of the lock box is provided with a receiving groove. The panel 2 is provided with several horizontally arranged rectangular through holes for limiting the latch tongue extending from the lock. The panel 2 is fixed to the bolting post 9 by screws and connected to the opening surface of the lock box body 1. The fixed base 3 is formed by stamping and bending sheet metal. One side of the fixed base 3 is bent upward to form a bolting part 11 and a connecting part 12, and the other side is bent downward to form a limiting part 13 and a riveting part 14. The center of the fixed base 3 is also provided with a guide groove 17. The bolting part 11 is provided with a fixing hole 16 for connecting and fixing the bolting post 9 at the bottom of the lock box body 1. One end of the 7 is provided with a limiting hole 18, and the riveting part 14 is provided with a riveting hole 10 for connection and fixation with the riveting hole 10 at the bottom of the lock box body 1; the movable seat 4 is formed by stamping and bending of sheet metal. One side of the movable seat 4 is bent upward to form a bending surface A19, a bending surface B20, and a bending surface C21. The bending surface B20 is provided with a roller hole 22 for placing the roller 8. The two sides of the bending surface B20 are provided with bending to form a connecting surface 23. The connecting surface 23 is provided with a connecting hole 24. The connecting shaft 7 passes through the connecting hole 24, the roller 8, and the connecting hole 24 in sequence to fix the roller 8 in the roller hole 22. The bending surface C21 is provided with a tapping hole 25. The two sides of the bending surface C21 are bent downward to form a limiting surface 26; the adjusting seat 5 is provided with an eccentric arc groove 28 and a circular protrusion 27. The circular protrusion 27 is provided with a cross groove for easy rotation; the roller 8 is provided with a central through hole, and the connecting shaft 7 is sleeved into the central through hole of the roller 8.

[0021] This embodiment provides an adjustable lock box. During connection and installation, the adjusting seat 5 is placed at the bent surface C21 of the movable seat 4, the eccentric arc groove 28 is aligned with the tapping hole 25, and the fixing seat 3 is placed on the adjusting seat 5, so that the limiting strip 15 and the limiting part 13 of the fixing seat 3 abut against the limiting surface 26 of the movable seat 4, the circular protrusion 27 of the adjusting seat 5 is placed in the limiting hole 18 of the fixing seat 3, the guide groove 17 is aligned with the tapping hole 25, and then the fixing screw 6 is passed through the guide groove 17, the eccentric arc groove 28, and the tapping hole in sequence. After the hole 25 is screwed into the tapping hole 25 and fixed, the fixed part is placed into the lock box body 1. One side of the roller 8 is placed into the receiving groove of the lock box body 1. After the rectangular hole of the panel 2 passes through the bending surface A19 of the moving seat 4, the side of the panel 2 is located at the lower end of the bending surface A19. The rest of the panel 2 covers the lock box body 1, and the bolted part 11 of the fixing seat 3 is pressed onto the bolted post 9 of the lock box body 1 and then fixed with bolts. The riveting hole 10 of the riveting part 14 is connected and fixed with the riveting hole 10 at the bottom of the lock box body 1.

[0022] This embodiment provides an adjustable lock box. In use, after the inclined surface of the latch on the door lock contacts the side of the bent surface A19 of the movable seat 4, the latch retracts back into the door lock and slides past the bent surface A19. After entering the bent surface B20, the latch pops out and slides past the roller 8. The latch and the bent surface B20 then abut against each other to form a lock. After locking, because the force is distributed from the bolt post 9 and the riveting joint to the entire lock box, and the panel 2 is fixed to the door frame, the pressure is transmitted from the panel 2 to the door frame. With the pressure distributed, the lock box body is not easily... Deformation occurs; when the gap between the back door and the door frame needs to be adjusted after installation, loosen the fixing screw 6 and then rotate the circular protrusion 27, which drives the adjusting seat 5 to rotate around the limiting hole 18. The rotation of the adjusting seat 5 drives the eccentric arc groove 28 to move. Since the fixing screw 6 is fixed in the tapping hole 25 and the fixing seat 3 is fixed in the lock box body 1, when the adjusting seat 5 rotates, the moving seat 4 and the fixing screw 6 move in the guide groove 17 of the fixing seat 3. After moving to the appropriate position, tighten the fixing screw 6 to fix it.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various changes and modifications can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
