Abstract
Description
Technical Field
[0001] This utility model relates to the field of insect-proof window screen technology, specifically to a window screen with insect-proof function. Background Technology
[0002] Window screens are frequently used in households. Their function is to block various flying insects and filter out debris entering the room when doors and windows are opened for ventilation. At the same time, window screens can also block the view to some extent.
[0003] While existing window screens can prevent insects from entering, smaller insects can still pass through, and some insects may even remain on the outside of the screen, rendering them ineffective at preventing insect infestation. Furthermore, most window screens are fixed in place, making installation and removal cumbersome. Therefore, there is an urgent need to design a window screen with insect-proof functionality to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a screen window with insect-proof function to overcome the above-mentioned shortcomings of the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A screen with insect-proof function includes two vertical frames and two horizontal frames. The two horizontal frames are arranged between the two vertical frames. Slide rails are provided on opposite sides of the two vertical frames. A winding box is engaged between the two vertical frames. A screen is provided inside the winding box. A pull plate is installed at one end of the screen. Both ends of the pull plate are slidably connected to the two slide rails. A baffle is engaged at one end of the winding box. A liquid storage box is provided inside the winding box. A cleaning block is provided in the liquid storage box. The cleaning block abuts against the screen. A frame slot is provided at one end of the winding box. A frame clamp is installed on one side of the baffle. The frame clamp engages with the frame slot. A cylindrical clamp is installed on the bearing. A cylindrical slot is provided at one end of the cylinder. The cylindrical clamp engages with the cylindrical slot. Clamping assemblies are provided in both horizontal frames.
[0007] Furthermore, the clamping assembly includes a sliding plate slidably connected within the transverse frame and a threaded rod rotatably connected within the transverse frame. The threaded rod is threadedly connected to the sliding plate. A triangular boss is elastically fitted at the bottom of the sliding plate, and a pull rod is mounted on the top of the triangular boss. The pull rod is slidably fitted within the transverse frame, and the two transverse frames are symmetrically arranged.
[0008] Furthermore, each of the two transverse frames has a through groove corresponding to the pull rod on both sides, the pull rod slides in the through groove, a spring is provided inside the triangular boss, and a knob is installed at one end of the threaded rod.
[0009] Furthermore, a bearing is rotatably connected to one side of the baffle, and a cylinder is rotatably fitted inside the winding box. One end of the cylinder is engaged with the bearing. A fixing rod is installed on one side of the baffle, and a torsion spring is provided between one end of the fixing rod and the bearing.
[0010] Furthermore, a cover corresponding to the liquid storage box is installed on one side of the baffle.
[0011] Furthermore, one of the transverse frames has a positioning groove at its top corresponding to the pull plate, and magnetic blocks are installed in both the pull plate and the positioning groove.
[0012] In the above technical solution, the screen window with insect-proof function provided by this utility model has the following beneficial effects:
[0013] The reservoir box allows the cleaning block to soak the mesh with insect repellent as it is pulled out of the winding box, reducing the entry of small insects and their attachment to the mesh, thus achieving a better insect-repellent effect. The included baffle allows for easy removal of the mesh after the winding box is disassembled, facilitating the disassembly and cleaning of the mesh and making maintenance convenient.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] like Figure 1-5 As shown in the figure, the present invention provides a screen window with insect-proof function, including two longitudinal frames 1 and two transverse frames 2. The two transverse frames 2 are arranged between the two longitudinal frames 1 and the two longitudinal frames 1. Slide rails 10 are provided on both sides of the two longitudinal frames 1. A rewind box 3 is snapped between the two longitudinal frames 1. A screen 4 is provided inside the rewind box 3. A pull plate 5 is installed at one end of the screen 4. The two ends of the pull plate 5 are slidably connected to the two slide rails 10. A baffle 18 is snapped at one end of the rewind box 3. The rewind box 3 is provided with... A liquid storage box 28 is provided for storing insect repellent liquid. A cleaning block 29 is provided in the liquid storage box 28, which abuts against the mesh 4. A frame slot 16 is provided at one end of the winding box 3. A frame clip 23 is installed on one side of the baffle 18, and the frame clip 23 is engaged with the frame slot 16. A cylindrical clip 20 is installed on the bearing 19. A cylindrical slot 15 is provided at one end of the cylinder 14, and the cylindrical clip 20 is engaged with the cylindrical slot 15. A clamp assembly 7 is provided in each of the two horizontal frames 2.
[0023] Specifically, in this embodiment, the clamp assembly 7 includes a slide plate 12 slidably connected in the transverse frame 2 and a threaded rod 9 rotatably connected in the transverse frame 2. The threaded rod 9 is threadedly connected to the slide plate 12. A triangular boss 13 is elastically fitted at the bottom of the slide plate 12. A pull rod 8 is installed on the top of the triangular boss 13. The pull rod 8 is slidably fitted in the transverse frame 2. The two transverse frames 2 are symmetrically arranged.
[0024] Both sides of the two horizontal frames 2 are provided with through slots 25 corresponding to the pull rods 8. The pull rods 8 slide in the through slots 25. A spring 11 is provided inside the triangular boss 13. A knob 6 is installed at one end of the threaded rod 9.
[0025] A bearing 19 is rotatably connected to one side of the baffle 18, and a cylinder 14 is rotatably fitted inside the winding box 3. One end of the cylinder 14 is engaged with the bearing 19. A fixing rod is installed on one side of the baffle 18, and a torsion spring 17 is provided between one end of the fixing rod and the bearing 19.
[0026] A cover 30 corresponding to the liquid storage box 28 is installed on one side of the baffle 18.
[0027] One of the horizontal frames 2 has a positioning groove 26 on its top that corresponds to the pull plate 5. Magnetic blocks are installed in both the pull plate 5 and the positioning groove 26.
[0028] Working principle: In use, align the frame consisting of two vertical frames and two horizontal frames with the window, and install and fix the frame using the clamp assembly. Then, snap the rewind box between the two vertical frames. Pull the pull plate to move it along the slide rails within the two vertical frames. The pull plate moves the screen out of the rewind box, allowing the screen to cover the window. When the pull plate reaches the positioning groove in the horizontal frame, the pull plate and the magnetic block in the positioning groove magnetically attract each other, fixing the pull plate in place. As the screen is removed from the rewind box, the cleaning block will soak the screen with insect repellent from the reservoir, making the screen insect-proof. Pushing the screen back into the rewind box and pulling it out again allows the screen to be re-soaked in insect repellent. After a period of use, move the pull plate to retract the screen into the rewind box, remove the snap-fit rewind box, open the baffle, and you can take the screen out of the rewind box for cleaning, while also replenishing the insect repellent in the reservoir.
[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
