When the locking column 311 moves upwards through the vertical rod 31, the locking column 311 can be driven to move upwards and inserted into the groove, so that the opening and closing window 3 and the window frame 1 are closed, which is convenient for locking. The locking column 311 and the corresponding groove provided in this application are common knowledge of those skilled in the art, and will not be described in detail.

[0030] In an embodiment further provided by the present invention, a driving block 41 is fixedly provided at one end of the transmission crossbar 4 , and when the opening and closing window 3 is in a closed state, the driving block 41 abuts against an abutting groove 501 provided on the driving crossbar 5 .

When the locking member is triggered, the rotating shaft 6 is relatively fixed to the fixing member 64. Specifically, the rotating member arranged in the present application can achieve locking of the position of the window when it is opened through the cooperation between the rotating member and the transmission cross bar 4 during use, that is, it can avoid locking the window when encountering accidental collision with wind or external force, and can ventilate more smoothly and stably, greatly improving the ventilation effect.

[0032] In an embodiment further provided by the present invention, the locking member includes a fixing column 63 fixedly arranged on the window frame 1, and one end of the transmission shaft 231 is inserted into the fixing column 63, and a first friction block 61 is fixedly arranged, and the cross section of the first friction block 61 is trapezoidal, and a second friction block 62 is slidably arranged inside the fixing column 63, and a trapezoidal groove is provided on the inner wall of the second friction block 62; The second friction block 62 is rotatably provided with a rotating block 621, and the rotating block 621 is provided with an inclined slot 6211.

Specifically, as Fig.12 As shown, there is a friction surface on the trapezoidal side surface of the first friction block 61, and a friction surface is also provided on the inner surface of the second friction block 62. The friction surface is adapted to the friction surface on the first friction block 61, that is, when the two are in contact, the first wiping module and the second friction block 62 can be relatively fixed, so that the opening and closing window 3 can be fixed when opened through the cooperation of other structures.

[0033] The present application provides structures such as ventilation components 2 on the window frame 1, and structures such as transmission components and rotating components on the opening and closing window 3, so that when the baffle 2311 blocks the opening, the air circulation between the outdoor and indoor is blocked. On the contrary, when the baffle 2311 does not block the opening, the air between the outdoor and indoor is connected, so that the outdoor air and the indoor air can be connected or blocked as needed without opening the window. At the same time, when opening the window, the handle 321 can be rotated by controlling the rotation, and the rotating component can be locked by driving the locking component, so that the window frame 1 and the opening and closing window 3 can be fixed, that is, the position of the device can be fixed when opening and closing, that is, the stability of the opening and closing window 3 at any opening position can be improved as a whole. Furthermore, the present application can cooperate with the ventilation component 2 and the different strokes of the rotating part through a transmission component, and can achieve different effects at different strokes, thereby greatly improving the functionality of the device.

[0034] When the present invention is used, there are the following situations: First, when the device is in a closed state, the opening and closing window 3 and the window frame 1 are in a closed state. At this time, the handle 321 is rotated so that the handle 321 drives the transmission gear 32 to rotate, that is, the slot 301 engaged with the transmission gear 32 can be driven to transmit, thereby driving the vertical rod 31 to move upward, so that the lock column 311 is inserted into the slot, and at this time, the driving block 41 provided on the rotating crossbar is in the abutting slot 501; When it is raining and the ventilation assembly 2 needs to be opened, the handle 321 is continued to be turned, and the inclined block 312 arranged above the vertical rod 31 is also moved upward, and the transmission cross bar 4 is squeezed by the inclined surface of the inclined block 312, so as to drive the transmission cross bar 4 to move in the direction close to the abutment groove 501, that is, it can be abutted in the abutment groove 501 through the lateral movement of the driving block 41, and drive the driving cross bar 5 to move synchronously, that is, it can drive the driving shaft 51 on the driving cross bar 5 to move, that is, it can squeeze the inclined plate 221 through the driving shaft 51 to move, and then the inclined plate 221 drives the connected telescopic rod 22 to move, and then the movable plate 21 connected to the telescopic end of the telescopic rod 22 starts to move, and synchronously drives the rotating plate 23 to move, that is, during the movement, because one end of the pull rope 233 is fixedly connected to the ventilation Shell 24, and then the pull rope 233 drives the connected transmission shaft 231 to rotate, that is, it can drive the pulley fixedly connected to the transmission shaft 231 to rotate, and then the adjacent pulley is rotated through the transmission belt 2312, that is, it can drive the baffle 2311 to rotate, so as to open the opening in the rotating plate 23 and realize the connection between indoor and outdoor; specifically, there is a torque spring on the rotating shaft 232 of the rotating plate 23 set in the present application. When it is not driven by the telescopic rod 22, the rotating plate 23 can be in a vertical state under the elastic force of its torque spring, that is, the upper and lower ends of the rotating plate 23 are tightly attached to the inner wall of the ventilation shell 24, and a torque spring is also provided on the rotating shaft 232 of the baffle 2311. When the rotating plate 23 is in a vertical state, the elastic force of the torque spring can be used to drive the baffle 2311 to close, so that the opening in the rotating plate 23 is closed.

[0035] When it is necessary to open the opening and closing window 3, the bracket rotates the rotating handle 321 in the opposite direction according to the above-mentioned window closing method, so that the vertical rod 31 is driven to move downward, and then the lock column 311 can be unlocked, and then the baffle 2311 is closed. When the opening and closing window 3 is opened to a suitable position, the handle 321 is rotated in the opposite direction again, the vertical rod 31 moves upward, and the transmission cross bar 4 is driven to move rightward. The transmission cross bar 4 drives the guide column 42 connected to the end to move in the direction of the rotating block 621, that is, it can squeeze the rotating block 621, so that the guide column 42 moves along the inclined groove 6211, and can drive the rotating block 621 to move downward, and then drive the second friction block 62 to move downward, so that the friction surface set in the second friction block 62 contacts the surface of the first friction block 61, that is, the second friction block 62 is relatively fixed to the first friction block 61, that is, it is also equivalent to the first friction block 61 on the rotating shaft 6 being relatively fixed to the fixed column 63, that is, the position of the opening and closing window 3 can be locked.

[0036] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
