Both ends of the connecting lock box 1 are provided with connecting mechanisms 2. Each connecting mechanism 2 includes a connecting component 3 and a connecting locking component 4. The connecting component 3 includes a base connecting rod 5 connected to the connecting lock box 1 and a superimposed connecting rod 6 disposed on the side of the base connecting rod 5 away from the connecting lock box 1. The connecting locking component 4 is disposed between the base connecting rod 5 and the superimposed connecting rod 6. Both ends of the connecting locking component 4 are correspondingly connected to the base connecting rod 5 and the superimposed connecting rod 6. A plurality of superimposed connecting rods 6 are provided, and each adjacent superimposed connecting rod 6 is provided with a corresponding connecting locking component 4 and connected through the corresponding connecting locking component 4. Specifically, this design sets connecting mechanisms 2 at both ends of the connecting lock box 1. The base connecting rod 5 and the stacked connecting rod 6 in the connecting mechanism 2, as well as the adjacent stacked connecting rods 6, are connected and fixed by the connecting locking assembly 4. This allows the connecting mechanism 2 to freely match the locking points according to the size of the door and window. The height of the opening sash can be increased by stacking similarly. Several stackable connecting rods 6 can be modularly installed at any door and window height to meet user needs. This also helps to save time and install quickly, improving productivity and work efficiency.

[0026] The connecting locking assembly 4 includes a base connecting locking assembly 30 and a superimposed connecting locking assembly 31. The base connecting locking assembly 30 is used to connect the base connecting rod 5 and the superimposed connecting rod 6 adjacent to the base connecting rod 5. The superimposed connecting locking assembly 31 is used to connect the adjacent superimposed connecting rod 6. The base connecting locking assembly 30 and the superimposed connecting locking assembly 31 have the same structure. The base connecting rod 5 is provided with a base connecting hole 7 at one end near the corresponding base connecting locking assembly 30. The base connecting locking assembly 30 is provided with a base connecting end 8 corresponding to the base connecting hole 7. The base connecting end 8 of the base connecting locking assembly 30 extends into the base connecting hole 7 and connects with the base connecting rod 5.

[0027] The superimposed connecting end 9 is arranged at both ends of the superimposed connecting locking assembly 31 between the adjacent superimposed connecting rods 6, and the superimposed connecting hole 10 is arranged at the adjacent two ends of the adjacent superimposed connecting rods 6 corresponding to the superimposed connecting end 9. The superimposed connecting end 9 is connected with the superimposed connecting rod 6 by extending into the superimposed connecting hole 10. Specifically, the base connecting locking assembly 30 and the superimposed connecting locking assembly 31 both include a multi-point locker 11 and a multi-point locking seat 12. The multi-point locker 11 is provided with a cylindrical connecting piece 13 and a clamping connecting piece 14. The multi-point locking seat 12 is provided with a cylindrical connecting part 15 and a clamping connecting part 16 corresponding to the cylindrical connecting piece 13 and the clamping connecting piece 14. The cylindrical connecting part 15 is provided with a cylindrical connecting groove 17.

The clamping connecting piece 14 is connected with the clamping connecting part 16 by extending into the clamping limiting groove 18 through the limiting hole 19.

[0028] In the embodiment, the cylindrical connecting piece 13 is composed of an eccentric cylinder 32 and a cylindrical lock sleeve 33. The bottom end of the eccentric cylinder 32 is formed with a cylindrical connecting end 34. The top end of the eccentric cylinder 32 is provided with a screw hole. The cylindrical connecting end 34 is arranged on the side of the eccentric cylinder 32 away from the central axis at the bottom, so that an eccentric structure is formed between the cylindrical connecting end 34 and the eccentric cylinder 32. The mounting seat 36 is provided with a cylindrical mounting hole 37. The cylindrical connecting end 34 of the eccentric cylinder 32 extends into the cylindrical mounting hole 37. Since the cylindrical connecting end 34 and the eccentric cylinder 32 are in an eccentric structure, the cylindrical connecting end 34 and the cylindrical mounting hole 37 on the mounting seat 36 are coaxial. Therefore, the eccentric cylinder 32 of the cylindrical connecting piece 13 is an eccentric part. When the sealing degree of the door and window locking is not enough, the eccentric cylinder 32 can be rotated by an external tool. Since the cylindrical lock sleeve 33 is fixed at the eccentric position of the cylindrical connecting piece 13, rotating the eccentric cylinder 32 can change the position of the cylindrical lock sleeve 33 and adjust the sealing performance of the window.

[0029] The clamping connecting piece 14 has a cylindrical part 20 and a limiting part 21. The limiting part 21 is arranged at one end of the cylindrical part 20 away from the multi-point locker 11.

Specifically, the clamping connecting piece 14 is arranged in a mushroom shape, so that the clamping connecting piece 14 is convenient to be positioned and fixed with the clamping limiting groove 18, and the overall anti-theft performance is improved. In this embodiment, the clamping connecting piece 14 is arranged in the clamping limiting groove 18 in a rotating manner. The clamping connecting piece 14 can rotate by 90° and -90° in the clamping limiting groove 18, so as to improve the anti-prying locking performance.

The clamping connecting piece 14 is convenient to be disassembled and assembled, and the connection strength is not affected. The limiting part 21 can be effectively clamped in the clamping limiting groove 18.
