[0023] As shown in the figure, the utility model discloses a lock box mechanism for a sliding window, including a guide seat 4, a guide groove is provided in the guide seat 4, an adjustment plate 1 that can be connected to the hinge assembly is slidably provided in the guide groove, a rotatable card piece 2 is provided on the guide seat 4, and the card piece 2 is used to cooperate with the positioning groove in the window sash. By rotating the card piece 2 and snapping it into the positioning groove on the window sash, the overall positioning installation on the window sash can be achieved. The adjustment plate 1 is provided with a clearance groove 22 at a position corresponding to the card piece 2, and both sides of the guide seat 4 have an integrally extended front positioning plate 5 and a rear positioning plate 5. Plate 11, a positioning seat 6 is installed between the front and rear positioning plates, and the front and rear positioning plates and the positioning seat are provided with corresponding positioning holes. By passing the positioning rivets through the positioning holes on the front and rear positioning plates and the positioning seat 6 and then riveting them, the positioning connection of the positioning seat 6 between the front and rear positioning plates can be achieved. A rotating block 8 is provided in the positioning seat 6, and a transmission hole 9 for inserting one end of the handle is provided in the middle of the rotating block 8. The side wall of the rotating block 8 is extendedly provided with a first transmission tooth 12, and the adjustment plate 1 has a second transmission tooth 13 that can engage with the first transmission tooth 12.

[0024] Furthermore, the guide seat 4 is made of stainless steel to ensure its strength, and the positioning seat 6 is made of plastic material, which can not only provide rotational support for the lightweight rotating block, but also achieve weight reduction and cost savings.

[0025] Furthermore, a limit plate 7 is detachably mounted on the positioning seat 6. A first cylindrical portion 10 and a second cylindrical portion 21 are provided on either side of the rotating block 8. The first cylindrical portion 10 is rotatably mounted within a first support hole 15 on the limit plate 7, and the second cylindrical portion 21 is mounted within a second support hole 16 on the positioning seat 6. With this structure, the limit plate 7 cooperates with the positioning seat 6 to achieve forward and backward positioning of the rotating block 8, ensuring that the rotating block 8 does not deviate axially. At the same time, the first and second support holes provide rotational support for the rotating block 8, ensuring that it can rotate normally.

[0026] Furthermore, the rotating block 8 is made of an alloy and is provided with a snap-fitting slot 20. The first cylindrical portion 10 and the second cylindrical portion 21 are made of plastic, each of which is provided with a snap-fitting protrusion 19 that snaps into the snap-fitting slot 20. This structure not only ensures the strength of the rotating block 8 and ensures that its first transmission teeth 12 can stably cooperate with the second transmission teeth 13 to achieve transmission, but also, the plastic material of the first and second cylindrical portions allows the rotating block 8 to be rotated and reduced in weight.

[0027] Furthermore, the guide seat 4 is provided with a positioning slot 3 at a position corresponding to the positioning seat 6. This facilitates the positioning of the guide seat when it is installed inside the window sash.

[0028] Furthermore, the structure further includes a transmission block 14, with the second transmission tooth 13 disposed on the transmission block 14. The adjustment plate 1 is provided with a slot, and a pin 17 is provided on the transmission block 14 to be inserted through the slot. A reinforcement plate 18 is fixedly mounted on the adjustment plate 1, and the pin 17 is inserted into the reinforcement plate 18 after passing through the slot. With the above structure, the appropriate transmission block 14 can be selected and snapped onto the adjustment plate 1 according to the required fit, and the reinforcement plate 18 ensures the stability of the connection between the adjustment plate 1 and the transmission block 14.

[0029] Furthermore, a handle mounting plate 26 is provided on the outside of the front positioning plate 5. The handle mounting plate 26 is provided with mounting holes 28 for mounting the handle. Of course, the front and rear positioning plates and the positioning seat 6 are also provided with corresponding through-holes corresponding to the mounting holes. An inserting portion 27 is extended from the handle mounting plate 26. The front positioning plate 5 is provided with a first insertion hole 23, the rear positioning plate 11 is provided with a second insertion hole 25, and the positioning seat 6 is provided with a third insertion hole 24. The inserting portion 27 passes through the first, second, and third insertion holes. By adopting the above structure, the assembly of the handle mounting plate 26 and the positioning plate can be easily achieved, and the handle mounting plate 26 and the handle can be assembled together.

[0030] The working principle of the present invention is as follows: the transmission column of the handle is inserted into the transmission hole 9 on the rotating block 8. By controlling the rotation of the handle, the rotating block 8 is driven to rotate. At this time, the first transmission tooth 12 drives the second transmission tooth 13, driving the adjustment plate 1 to move under the guidance of the guide seat 4, thereby driving the hinge structure connected to the adjustment plate 1 to move, thereby realizing the switching of the window sash between the sliding state, the inward tilting state or the locked state. And when assembling the lock box of this structure, the rotating block can be first set in the positioning seat 6, and the other structures can be set in the guide seat 4. Then, the positioning seat 6 is inserted between the front positioning plate 5 and the rear positioning plate 11. Then, the positioning pin or screw is inserted into the front and rear positioning plates and the positioning seat 6 to achieve positioning.

[0031] The structure of the present invention has a reasonable overall structural design. By integrally extending the front positioning plate and the rear positioning plate on both sides of the guide seat, the number of parts is simplified and the installation and disassembly of the subsequent positioning seat can be facilitated. At the same time, the structure of the transmission teeth meshing transmission between the rotating block and the adjusting plate is adopted to ensure the stability and switching accuracy of the lock box switching transmission, so that the subsequent window sashes can be accurately switched to the required state, effectively improving the user experience.
