The dustproof mechanism 4 includes two sets of symmetrically distributed winding rods 402, and the two sets of winding rods 402 are located at both ends of the slider 302. The support rod 301, the ratchet 310 and the pawl 311 in the sliding support mechanism 3 are used to maintain the opening angle and the opening state of the opening window 2, so as to avoid the failure of the sliding support due to the pressure when the wind pressure is large during the use of the opening window 2, and the curtain wall is damaged by the impact caused by the gravity closing of the opening window 2.

[0027] In this embodiment, reference Figure 2 , Figure 3 and Figure 4As shown, two groups of symmetrically distributed first screw rods 303 are provided in the opening window 2, and two groups of symmetrically distributed second screw rods 304 are provided in the installation frame 1, and the first screw rods 303 and the second screw rods 304 are both arranged corresponding to the support rod 301, a first transmission belt 306 is provided in the opening window 2, and a second transmission belt 308 is provided in the installation frame 1, the two groups of first screw rods 303 respectively penetrate the slider 302 on the left side of the support rod 301 and are threadedly connected to the slider 302, the two groups of second screw rods 304 respectively penetrate the slider 302 on the right side of the support rod 301 and are threadedly connected to the slider 302, the two groups of first screw rods 303 are sleeved with a first transmission wheel 305, and the two groups of second screw rods 304 are sleeved with a second transmission wheel 306. The first transmission belt 306 is connected to the two sets of first transmission wheels 305, and the two sets of second transmission belts 308 are connected to the two sets of second transmission wheels 307. The ratchet 311 is rotatably connected to the mounting frame 1 through the mounting shaft 312. The mounting shaft 312 is sleeved with a first torsion spring 313, and the two ends of the first torsion spring 313 are fixedly connected to the ratchet 310 and the mounting frame 1 respectively. The mounting shaft 312 is sleeved with a gear 314. The mounting frame 1 is provided with a rack 315 meshing with the gear 314, and the rack 315 is provided with a handle bar 316. The handle bar 316 penetrates the mounting frame 1 and is slidably connected to the mounting frame 1. The mounting frame 1 is provided with a fixed The fixed rod 318 and the handle rod 316 are provided with an elastic card plate 317, the fixed rod 318 and the elastic card plate 317 are correspondingly arranged, and the fixed rod 318 is provided with two groups of symmetrically distributed card rods 319, the two groups of card rods 319 are rotatably connected with the fixed rod 318, and the fixed rod 318 is sleeved with a second torsion spring 320, and the two ends of the second torsion spring 320 are respectively fixedly connected with the card rod 319 and the fixed rod 318, and the two groups of card rods 319 are movably connected with the elastic card plate 317, and the slider 302 cannot slide freely in the opening window 2 and the installation frame 1 under the action of the first screw rod 303 and the second screw rod 304, so that the opening window 2 cannot be closed at will, and at the same time The opening of the open window 2 drives the mounting rod 309 and the ratchet 310 fixed on the mounting rod 309 to rotate clockwise, and the first torsion spring 313 maintains the angle of the pawl 311. At this time, the pawl 311 will not limit the rotation of the ratchet 310. If the open window 2 is pushed closed forcefully under the action of wind pressure, the open window 2 tends to rotate counterclockwise, driving the ratchet 310 to rotate counterclockwise. At this time, under the action of the pawl 311, the ratchet 310 and the open window 2 cannot rotate counterclockwise. Under the action of the screw rod, the slider 302 and the support rod 301, the opening angle of the open window 2 is further limited and guaranteed to prevent the open window 2 from being forcefully closed under external force.

[0028] In this embodiment, reference Figure 5 and Figure 6As shown, two groups of winding rods 402 are provided with dustproof cloth 401, and the two ends of the dustproof cloth 401 are respectively wound on the winding rods 402, and the dustproof cloth 401 is clamped with the slider 302, and the two ends of the winding rods 402 are sleeved with two groups of symmetrically distributed coil springs 403, and the inner and outer ends of the coil springs 403 are respectively fixedly connected to the winding rods 402 and the mounting frame 1 or the opening window 2. During the up and down sliding process of the slider 302, the two groups of winding rods 402 are coordinated to ensure that the dustproof cloth 401 is always in a tightened state and clamped in the slide groove, so as to provide dustproof protection for the slide groove and avoid dust accumulation in the slide groove.

[0029] When the present embodiment is working, the motor drives the first screw rod 303 and the second screw rod 304 to rotate respectively, and under the action of the first transmission belt 306, the first transmission wheel 305, the second transmission belt 308 and the second transmission wheel 307, the two groups of first screw rods 303 and the second screw rods 304 rotate synchronously, and the two groups of sliders 302 set in the opening window 2 and the fixed frame are pushed smoothly, the support angle of the support rod 301 is changed, and the opening of the opening window 2 is realized, and under the action of the first screw rod 303 and the second screw rod 304, the slider 302 cannot slide freely in the opening window 2 and the mounting frame 1, so that the opening window 2 cannot be closed at will. At the same time, the opening of the opening window 2 drives the mounting rod 309 and the ratchet 310 fixed on the mounting rod 309 to rotate clockwise, and the first torsion spring 313 maintains the angle of the pawl 311. At this time, the pawl 311 will not limit the rotation of the ratchet 310. If the opening window 2 is strongly pushed to close under the action of wind pressure, the opening window 2 will rotate counterclockwise. The ratchet wheel 310 has a tendency to rotate counterclockwise. At this time, the ratchet wheel 310 and the window 2 cannot rotate counterclockwise under the action of the pawl 311. The opening angle of the window 2 is further limited and guaranteed under the action of the screw rod, the slider 302 and the support rod 301 to prevent the window 2 from being closed by force under the external force. When the window 2 really needs to be closed, the rack 315 is moved downward by pulling the handle bar 316 downward, and the gear 314 meshing with the rack 315 drives the mounting shaft The handle 316 is pulled down so that the elastic card plate 317 is engaged with the two sets of card rods 319 to fix the position of the rack 315. At the same time, when the slider 302 slides up and down, the two sets of winding rods 402 cooperate to ensure that the dustproof cloth 401 is always in a taut state and engaged in the slide groove, so as to provide dustproof protection for the slide groove and avoid dust accumulation in the slide groove.

[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0031] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
