Description

Technical Field

[0001] The utility model belongs to the field of push-pull screen windows, in particular to a screen window with a push-pull screen fan capable of being suspended. Background Art

[0002] In common two-push and three-push push-pull screens, the screen fan is installed along the window frame, and the screen window is opened and closed by pushing and pulling the screen fan up and down. In order to adjust the size of the opening part of the screen fan according to the required ventilation conditions, it is necessary to set a suspension control device on the screen fan so that the screen fan can be suspended and started during the pushing and pulling process. The existing suspension control device allows the screen fan to suspend on the window frame through elastic abutment. However, the elastic abutment has no constraints. In addition to the elastic deformation direction, the elastic abutment will also produce displacements in other directions, which will inevitably cause the screen fan to swing. Utility Model Content

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the suspension control screen window includes a screen fan 1, a fan frame 2 and an invisible automatic latch 3. The side of the screen fan 1 is installed in the profile groove of the fan frame 2 through four suspension control devices 4. The joint of the two screen fans 1 is installed with a latch 3 ( Figure 1 Only one gauze fan on the upper part is drawn, and the other gauze fan on the lower part is not drawn)

[0022] like Figure 1 , 2 As shown in Figures 3 and 4, the suspension control device 4 includes a fixed seat 5, which is provided with a mounting cavity 6. The slider 8 abuts against the fixed seat 5 through the ball 13 and the first spring 12 in sequence. The ball 13 and the first spring 12 are built into the mounting cavity 6. The mounting cavity 6 is provided with a mounting hole 7. The slider 8 is slidably installed along the mounting hole 7. The slider 8 can protrude from the mounting hole 7. The slider 8 is provided with limit plates 9 on both sides. The limit plates 9 are built into the mounting cavity 6. The mounting cavity 6 is provided with a retaining ring 10. The limit plates 9 are hooked to the retaining ring 10. The slider 8 is provided with a through hole 11. The first spring 12 passes through the through hole 11. The ball 13 is limited and protrudes from the opening of the through hole 11.

[0023] The ball 13 with the elastic force of the first spring 12 slides in the profile groove of the fan frame 2, and the slider 8 performs telescopic movement along the installation cavity 6, forming a motion track with a limiting function in the installation cavity 6, effectively avoiding the swing of the yarn fan 1 caused by the slider 8 deviating from the motion track.

[0024] like Figure 1 , 4 As shown in Figure 5, the invisible automatic latch 3 includes a handle 14, a fastener 15, a lock 16 and a base 17. The base 17 is provided with a cavity 18. The base 17 is embedded in the handle 14. The base 17 is screwed to the bottom of one screen fan, and the lock 16 is screwed to the top of another screen fan. The handle 14 is screwed to the fastener 15, and the fastener 15 is slidably installed in the cavity 18. The fastener 15 abuts against the inner wall of the cavity 18 through the second spring 19. The fastener 15 is provided with a clamping platform 20, and the lock 16 is provided with a clamping hook 21.

[0025] When the upper yarn fan is pulled down to close with the lower yarn fan, the hook 21 is inserted from the bottom of the handle 14 into the handle 14 and extends into the cavity 18. The hook 21 engages with the clamping platform 20 and automatically locks the two yarn fans. When the handle 14 is turned to the left, the fastener 15 slides along the cavity 18, the clamping platform 20 is disengaged from the hook 21, and the upper yarn fan is pushed and pulled upward to unlock the two yarn fans. When the handle 14 is reset under the action of the second spring 19, the next automatic locking process is entered. When the yarn fan is closed, the fastener 15 and the lock buckle 16 are automatically engaged and locked, avoiding the tediousness of manual locking; when the handle 14 is turned to the left to slide, the fastener 15 and the lock buckle 16 are automatically unlocked, which is very convenient to operate.

[0026] like Figure 1 , 6 As shown in Figures 7 and 8, in order to prevent the danger of children climbing through the window and falling due to misoperation, a code wheel 22 is installed on the handle 14. A rotating shaft seat 23 is provided on the back of the handle 14, and a clamping column 24 is provided on the base 17. The code wheel 22 includes a stepped code disk 22a and a limit platform 22b. The code disk 22a and the limit platform 22b are pressed against the base 17 by a third spring 25. The code disk 22a is sleeved on the rotating shaft seat 23, and the limit platform 22b is provided with a notch 26. The notch 26 corresponds to a digital code 27 of the code disk 22a. The digital code 27 is marked with numbers 0-9, and the numbers 0-9 are evenly distributed on the surface of the code disk 22a along the circumferential direction. An observation port 28 is provided on the top surface of the handle 14, and the digital code 27 of the code disk 22a is exposed from the observation port 28. A toggle port 29 is provided on the side of the handle 14, and a part of the outer edge of the code disk 22a is exposed from the toggle port 29.

[0027] Assuming that "9" is set as the unlocking password, the outer edge of the code disk 22a is dialed along the dialing hole 29. When the code disk 22a is rotated to the "9" position, the notch 26 is aligned with the clamping column 24, and the handle 14 is pushed to make the fastener 15 slide along the cavity 18. At the same time, the notch 26 slides along the clamping column 24, so that the clamping platform 20 is disengaged from the hook 21, and the upper screen fan is pushed upward to unlock the two screen fans. When the handle 14 is reset to lock, the outer edge of the code disk 22a is dialed along the dialing hole 29 again, so that the code disk 22a is rotated to any position from "0" to "8". Since the notch 26 is not aligned with the clamping column 24, the limit platform 22b is limited by the clamping column 24, so the handle 14 cannot be pushed, ensuring the locked state.
