Description

Technical Field

[0001] This utility model relates to the field of screen technology, and in particular to a lightweight laser-welded narrow-frame soundproof detachable screen. Background Technology

[0002] In modern building window and door systems, screens are widely used in various residential and public buildings as an important accessory for ventilation and insect prevention. With the increasing demands for building energy conservation and improved living environment quality, screens not only need to meet basic functional requirements but also require comprehensive improvements in sound insulation, lightweight structure, ease of installation, and service life. Especially against the backdrop of rapid urbanization and increasing residential density, users have placed higher demands on the sound insulation and maintainability of screens, driving continuous optimization and innovation in related technologies.

[0003] Currently, most common window screens on the market use traditional metal welding or splicing structures, resulting in wide frames and significant weight. This not only affects the overall aesthetics but also limits light transmission efficiency. In terms of sound insulation, existing window screens generally lack dedicated noise reduction designs. Friction between the slider and the track, and collisions between the frames, easily generate noise during sliding, affecting the quietness of the indoor environment. Furthermore, many products still rely on complex screw fixings or non-removable structures for installation, leading to difficulties in cleaning, replacing the screen, or maintenance, increasing operating costs. Simultaneously, some lightweight products, while pursuing weight reduction, neglect structural strength, making them prone to deformation and poor sliding, affecting lifespan and user experience. Therefore, there is an urgent need to develop a new type of window screen that integrates lightweight design, laser-welded narrow frames, sound insulation and noise reduction, and quick installation and removal functions to effectively address the aforementioned shortcomings of existing technologies and meet the comprehensive needs of modern buildings for high-quality door and window accessories.

[0004] Therefore, in response to the problems of existing window screens being heavy, noisy, and inconvenient to disassemble, there is a need for a lightweight laser-welded narrow-frame soundproof detachable window screen that can solve the above problems. Utility Model Content

[0005] To address the issues of heavy weight, high noise levels, and inconvenient disassembly in existing screen window technologies, this application provides a lightweight laser-welded narrow-frame soundproof detachable screen window. Through multiple noise reduction designs, the sound insulation effect is enhanced. A U-shaped rubber sealing strip is installed within the screen window frame's sliding groove to reduce sliding friction noise, and a stepped rubber strip protrusion on the outer wall of the sliding frame buffers collision sounds, effectively reducing opening and closing noise and creating a quiet and comfortable home environment.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A lightweight, laser-welded, narrow-frame, soundproof, detachable screen window includes a screen frame. Fixed mesh screens are fixedly connected to the front and rear ends of the inner wall of the screen frame. A sliding frame is connected to the inner wall of the front end of the screen frame via a sliding component. A movable mesh screen is fixedly connected to the inner wall of the sliding frame. An installation frame is provided at the lower end of the screen frame. Slots are provided on both the left and right ends of the inner wall of the installation frame.

A toggle block is fixedly connected to the front end of each slot. A spring is provided at one end of each slot, and the other end of each slot engages with the inner wall of the slot. A fixing pin is fixedly connected to the front end of the inner wall of the installation frame. A guide groove is provided on the front end of the outer wall of the screen frame, and the outer wall of the fixing pin is slidably connected to the inner wall of the guide groove.

[0008] As a further improvement of this utility model, the sliding component includes a sliding groove formed at the front end of the inner wall of the screen frame, a sealing strip fixedly connected to the inner wall of the sliding groove, a slider slidably connected to the inner wall of the sealing strip, and the slider fixedly connected to the outer wall of the sliding frame.

[0009] As a further improvement of this utility model, the sealing strip is a U-shaped rubber strip, and the outer wall of the sliding frame is provided with stepped sealing strip protrusions.

[0010] As a further improvement of this utility model, one end of the spring is connected to one end of the locking block, and the other end of the spring is connected to the inner wall of the crossbeam.

[0031] Example 1:

[0032] like Figures 1-3As shown, a lightweight laser-welded narrow-frame soundproof detachable screen window includes a screen window frame 1, a crossbeam 7 fixedly connected to the middle of the screen window frame 1, fixed screen mesh 3 fixedly connected to the front and rear ends of the inner wall of the screen window frame 1, a sliding groove 10 opened at the front end of the inner wall of the screen window frame 1, a sealing strip 11 fixedly connected to the inner wall of the sliding groove 10, the sealing strip 11 is a U-shaped rubber strip, a stepped sealing strip protrusion is provided on the outer wall of the sliding frame 4, a slider 6 is slidably connected to the inner wall of the sealing strip 11, the slider 6 is fixedly connected to the outer wall of the sliding frame 4, a movable screen mesh 5 is fixedly connected to the inner wall of the sliding frame 4, a combination lock 16 is provided at the rear end of the sliding frame 4 for fixing the sliding frame 4 to the front end of the crossbeam 7, and an installation frame 2 is provided at the lower end of the screen window frame 1. The screen window frame 1, the installation frame 2 and the sliding frame 4 are all made of aluminum alloy profiles and are all hollow thin-walled structures. The screen window frame 1, the installation frame 2 and the sliding frame 4 are all made of seamless laser welding technology.

[0033] Specifically, the frame of this screen window is made of aluminum alloy profiles, combined with a hollow thin-walled structure and laser welding seamless technology, which not only significantly reduces the overall weight, but also achieves a smooth appearance without obvious weld seams at the welding position. To solve the noise problem during the sliding process, on the one hand, a U-shaped rubber sealing strip 11 is fixedly connected in the sliding groove 10 on the inner wall of the front end of the screen window frame 1, which reduces the noise by 80% when the sliders 6 at both ends of the sliding frame 4 slide. On the other hand, a stepped sealing strip protrusion is set on the outer wall of the sliding frame 4, which effectively reduces the sound generated by the collision between the sliding frame 4 and the screen window frame 1. The dual design achieves a good sound insulation effect. In terms of safety protection, the sliding frame 4 is fixed to the crossbeam 7 by the combination lock 16 at the rear end. When opening, the correct code must be entered first to unlock, and then it can be slid open back and forth.

[0034] Example 2:

[0035] As one of the optimized structural designs for Example 1, such as Figure 1 , Figure 4 and Figure 5 As shown, the inner wall of the mounting frame 2 has slots 15 on both the left and right ends. The inner walls of the left and right ends of the crossbeam 7 are slidably connected to the locking blocks 12. The front end of the locking blocks 12 is fixedly connected to the actuating block 13. A spring 14 is provided at one end of the locking blocks 12. One end of the spring 14 is connected to one end of the locking blocks 12, and the other end of the spring 14 is connected to the inner wall of the crossbeam 7. The other end of the locking blocks 12 is locked into the inner wall of the slot 15. A fixing pin 8 is fixedly connected to the front end of the inner wall of the mounting frame 2. A guide groove 9 is provided at the front end of the outer wall of the screen frame 1. The outer wall of the fixing pin 8 is slidably connected to the inner wall of the guide groove 9. Several mounting holes 17 are provided at the upper end of the mounting frame 2 for fixing the mounting frame 2 to the window frame.

[0036] Specifically, during installation, first use screws to fix the mounting frame 2 to the inside of the window frame through the mounting hole 17. Then, fit the guide groove 9 at the front end of the screen frame 1 onto the outer wall of the fixing pin 8 at the front end of the inner wall of the mounting frame 2. Finally, the upper end of the screen frame 1 is fixed by the engagement of the clip 12 and the slot 15. When disassembling, cleaning, or replacing, simply slide the sliding frame 4 forward first, and then simultaneously move the actuating blocks 13 on the left and right sides of the front end of the crossbeam 7 towards the center. The movement of the actuating blocks 13 will drive the clip 12 to move towards the center and squeeze the spring 14. After the clip 12 disengages from the slot 15, the mounting frame 2 can be moved upward and removed, thereby achieving quick disassembly of the mounting frame 2, the fixed screen 3, and the movable screen 5. Traditional disassembly takes 5 minutes, while this solution can be completed in 30 seconds.

[0037] Working principle: By fixing a U-shaped rubber sealing strip 11 to the groove 10 on the inner wall of the front end of the screen frame 1, the noise is reduced by 80% when the sliders 6 at both ends of the sliding frame 4 slide within the groove 10. A stepped sealing strip protrusion on the outer wall of the sliding frame 4 reduces the noise generated by the collision with the screen frame 1 during sliding, achieving a sound insulation effect. The sliding frame 4 is fixed to the crossbeam 7 via a combination lock 16 at the rear end. To open the sliding frame 4, the correct combination must be entered first, and then the lock can be opened to allow the sliding frame 4 to slide back and forth. When installing this screen window, first use screws to install the mounting frame 2 inside the window frame through the mounting hole 17. Then, fit the guide groove 9 at the front end of the screen window frame 1 onto the outer wall of the fixing pin 8 at the front end of the inner wall of the mounting frame 2. Then, fix the screen window frame 1 to the upper end of the mounting frame 2 by the engagement of the locking block 12 and the locking groove 15. When disassembling, simply slide the sliding frame 4 forward first, and then simultaneously move the actuating blocks 13 on both sides of the front end of the crossbeam 7 towards the middle. The movement of the actuating blocks 13 causes the locking block 12 to move towards the middle and compress the spring 14. When the locking block 12 disengages from the locking groove 15, the mounting frame 2 can be moved upward and removed.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
