Thus, by providing the first and second transmission structures, the transmission between the handle 1 and the transmission rod 3 can be achieved.

[0027] In this embodiment, the rack 201 and the locking block 202 are both integrally formed on the transmission block 2.

[0028] In this embodiment, the transmission rod 3 is provided in two parts and is located on the upper and lower sides of the transmission block 2 respectively.

[0029] See Figure 3-5The locking structure also includes a pressure plate 7 fixedly mounted on the door / window frame 10. The pressure plate 7 has at least one elastic positioning device 8, and the gear 6 has several positioning grooves 601 spaced circumferentially. When the handle 1 is rotated, the positioning grooves 601 on the gear 6 can selectively engage with the elastic positioning device 8 to position the handle 1. Specifically, the elastic positioning device 8 includes a spring 801 and a ball bearing 802 abutting against one end of the spring 801. The pressure plate 7 has an installation groove 701, and both the spring 801 and the ball bearing 802 are disposed within the installation groove 701, with the ball bearing 802 at least partially extending out of the installation groove 701. The ball bearing 802 is used to engage with the positioning groove 601 to position the handle 1.

[0030] Therefore, by setting the elastic positioning device 8 to position the rotation of the handle 1, when the handle 1 is rotated to a certain angle and positioned, the handle 1 drives several locking points 4 to respectively engage with several lock seats 5 to lock the door and window sash 11; when the handle 1 is rotated to reset and positioned again, the handle 1 drives several locking points 4 to disengage from several lock seats 5 to unlock the door and window sash 11.

[0031] In this embodiment, the elastic positioning device 8 is provided in a set, and the gear 6 is provided with three positioning grooves 601 spaced apart in the circumferential direction, so that the handle 1 has three positioning positions to meet the usage requirements.

[0032] Furthermore, it also includes a handle housing 9 connected and fixed to the door and window frame 10, with the pressure plate 7 fixed to the handle housing 9; the handle 1 is rotatably disposed within the handle housing 9. Specifically, the handle housing 9 has a receiving groove 901 with an open front end, and the handle 1 is rotatably disposed within the receiving groove 901 and can partially extend out of the receiving groove 901.

[0033] Thus, during assembly, the handle 1 can be first assembled into the handle housing 9, and then the handle housing 9 can be installed onto the door and window frame 10 as a whole, making the installation simple and the operation convenient.

[0034] In this embodiment, the pressure plate 7 is fixed to the handle housing 9 by bolts, and the handle housing 9 is fixed to the door and window frame 10 by bolts.

[0035] In this embodiment, the locking point 4 is an eccentric adjustment pin. Thus, by rotating the eccentric adjustment pin, the position of the locking point 4 can be adjusted, thereby changing the sealing amount and adapting to different usage scenarios.
