Description

Technical Field

[0001] The invention relates to the technical field of screen window manufacturing, and in particular to a more stable coil spring sand-hiding structure. Background Art

[0002] In modern buildings and home environments, screens are key components that isolate mosquitoes and dust and ensure indoor ventilation, and their functionality and user experience have attracted much attention. Invisible screens have gradually become the mainstream choice in the market due to their hidden installation and beautiful appearance. However, the matching rolling screen structure has long been plagued by many thorny problems, which have restricted the further optimization and upgrading of invisible screens.

[0003] Traditional invisible screens mostly rely on twisted springs to achieve the mesh rewinding function. The twisted spring itself has significant structural disadvantages. When subjected to force, the stress is concentrated at the intersection of the spiral lines, which can easily cause local deformation, resulting in uneven rewinding force and greatly reduced effect. In the process of frequent opening and closing of the screens in daily life, the springs are repeatedly twisted and stretched, and they may become weak and stuck in just a few months, and their stability is worrying. Especially when faced with the demand for large screens with a length of more than 3 meters, the twisted spring has insufficient elastic reserve and cannot provide sufficient rewinding force. After the mesh is stretched, it is difficult to return to its original position quickly and smoothly. The limitations are fully exposed, which greatly restricts the promotion and application of invisible screens in the field of large-size windows.

[0004] At the same time, the smoothness of the sliding of the gauze is also a major "pain point" of the existing winding structure. In order to standardize the movement trajectory of the gauze, plastic sheets are often used as guide devices. However, in actual operation, the friction coefficient between the plastic sheet and the gauze and window frame is high. Every time the gauze is pulled, it seems to be "moving forward with difficulty" and feels jerky. The harsh noise caused by friction not only disturbs the quiet atmosphere in the room, but in the long run it is more likely to cause users to be irritable and reduce the comfort of use. According to actual scene tests, the peak noise of ordinary household invisible screens can reach more than 60 decibels when pulled, which is comparable to the sound of noisy indoor conversations, seriously affecting the quality of life.

[0005] Furthermore, the problem of mesh tightening has always plagued the development of the industry. The existing winding structure lacks effective tightening means, and the mesh is very easy to loosen in the repeated pulling and rewinding cycle. The mesh holes of the loosened mesh are deformed, mosquitoes take advantage of the opportunity to enter, and the mosquito repellent effect plummets; the lack of tension also accelerates the wear of the mesh, shortens the service life, and frequent replacement of the mesh increases the economic burden and inconvenience of use for users. Market research data shows that more than 70% of users have reported that they have encountered the problem of loose mesh in invisible screens, and the demand for repair and replacement is urgent, highlighting the urgency of improving the existing winding structure.

[0006] To sum up, it is imperative to develop a new, efficient and stable coil spring hidden sand structure to fill the technical gap in the industry and meet market demand in all aspects. Summary of the invention

[0007] In order to solve the above problems, especially to address the deficiencies in the prior art, the present invention provides a more stable coil spring sand-hiding structure that can solve the above problems.

[0008] To achieve the above purpose, the present invention adopts the following technical means:

[0009] A more stable coil spring hidden sand structure comprises two groups of symmetrically distributed window frames, tracks are inserted in the window frames, a plastic sheet is slidably inserted between the two groups of tracks, the plug-in end of the plastic sheet is connected to a silent roller assembly that slides with the track, the bottom of the plastic sheet is connected to a first adsorption block, the tops of the two groups of window frames are connected to a scroll shell, the bottoms of the two groups of window frames are connected to a frame, a winding shaft is rotatably connected in the scroll shell, both ends of the winding shaft are respectively connected to an eight-shaped winding drive assembly arranged on the outside of the scroll shell, the winding shaft is connected to the plastic sheet through a gauze, the gauze is slidably inserted in the track, a spring sheet corresponding to the gauze is connected in the track, the top of the frame is connected to a second adsorption block corresponding to the first adsorption block, and the second adsorption block is adsorbed and connected to the first adsorption block.

[0010] A further solution of the present invention is that the figure-eight winding and unwinding drive assembly includes a driving shell, a driving shell cover is connected to the opening of the driving shell, an energy storage wheel and a driving wheel are connected inside the driving shell, the energy storage wheel is transmission-connected to the driving wheel, the driving wheel is transmission-connected to the winding and unwinding shaft, a volute spring is wound on the driving wheel, and the outer end of the volute spring is fixedly connected to the outer circumferential surface of the energy storage wheel.

[0011] A further solution of the present invention is that a windproof sheet is connected to the side of the gauze.

[0012] A further solution of the present invention is that an outer side surface of the plastic sheet is connected to an outer convex handle.

[0013] A further solution of the present invention is that the plastic sheet and the convex handle are made in one piece.

[0014] A further solution of the present invention is that both the first adsorption block and the second adsorption block are bar-shaped magnetic products.

[0015] A further solution of the present invention is that the silent roller assembly includes a bearing rotatably connected to the plastic sheet, the bearing is connected to a hub, and the outer side of the hub is sleeved with a roller.

[0016] A further solution of the present invention is that the roller is a rubber product and the bearing is a low friction coefficient bearing.

[0017] A further solution of the present invention is that the track is provided with two groups of track grooves, the end of the plastic sheet is a Y-shaped end, one side of the Y-shaped end of the plastic sheet is connected to the gauze and is slidably plugged with a group of corresponding track grooves, the spring sheet is arranged in one group of the track grooves, and the other side of the Y-shaped end of the plastic sheet is connected to the silent roller assembly and is slidably plugged with another group of corresponding track grooves.

[0018] A further solution of the present invention is that the spring sheet is made of stainless steel with excellent elasticity.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention has excellent stability. Upgraded coil spring structure: The key is to use an eight-shaped coiling and unwinding drive component to replace the traditional twisted spring. The eight-shaped coiling and unwinding drive component alternately circulates between the synchronously counter-rotating drive wheel and the energy storage wheel through the spiral spring, and is matched with the mutually meshing drive gear and energy storage gear, so as to realize the functions of unwinding energy storage and energy release and rewinding; by designing the diameter width of the drive gear to be smaller than the diameter width of the energy storage gear, it is easier to unwind the curtain and release the curtain faster; the elastic force attenuation amplitude of the spiral spring is controlled in a very small range, which is much lower than the twisted spring, and can be stable. It is suitable for stretching requirements of up to 6 meters, providing reliable power support for large screens, and completely breaking the limitations of traditional winding structures in large-size applications; the screen is securely fastened: the spring sheets on the edge of the screen play an important role. The spring sheets continuously apply appropriate tension to ensure that the screen is always tight no matter what opening or closing state it is in, which effectively prevents the screen from loosening or deforming. The stable screen structure not only improves the mosquito and insect prevention effect, but also greatly reduces the wear caused by the shaking and friction of the screen, which increases the durability of the screen by about 50% and reduces the trouble and cost of frequent replacement of the screen.

[0021] 2. The present invention provides a smooth and silent use experience. Ultra-low friction sliding: The rollers equipped on the edge of the plastic sheet convert sliding friction into rolling friction, and the friction force is reduced by more than 80%. This makes the screen feel light and smooth to pull, and even elderly people and children with less strength can easily open and close the screen; users no longer have to deal with the problem of the screen getting stuck or difficult to pull in daily use, and the operation is smooth and natural; nearly silent effect: The rollers are made of wear-resistant, noise-reducing rubber material, and are matched with low-friction bearings built into the wheel hub, which successfully controls the noise generated by the opening and closing of the screen to an extremely low level, creating a quiet and comfortable environment for homes, offices and other places, and preventing noise from interfering with life and work.

[0033] Example 1

[0034] As attached Figure 1-4 As shown, the present invention provides a more stable coil spring hidden sand structure, comprising two groups of symmetrically distributed window frames 10, wherein tracks 11 are inserted in the window frames 10, and a plastic sheet 6 is slidably inserted between the two groups of tracks 11, and the plug-in end of the plastic sheet 6 is connected to a silent roller assembly 8 that slides with the track 11, and the bottom of the plastic sheet 6 is connected to a first adsorption block 7, and the tops of the two groups of window frames 10 are connected to a reel shell 1, and the bottoms of the two groups of window frames 10 are connected to a frame 13, and a reel shaft 2 is rotatably connected in the reel shell 1, and the two ends of the reel shaft 2 are respectively connected to an eight-shaped reel driving assembly 3 arranged outside the reel shell 1, and the reel shaft 2 is connected to the plastic sheet 6 through a gauze 4, and the gauze 4 is slidably inserted in the track 11, and a spring sheet 12 corresponding to the gauze 4 is connected in the track 11, and a second adsorption block 14 corresponding to the first adsorption block 7 is connected to the top of the frame 13, and the second adsorption block 14 is adsorbed and connected to the first adsorption block 7;

[0035] The figure-eight winding drive assembly 3 includes a driving shell 302, a driving shell cover 301 is connected to the opening of the driving shell 302, an energy storage wheel 303 and a driving wheel 305 are connected inside the driving shell 302, the energy storage wheel 303 is transmission-connected to the driving wheel 305, the driving wheel 305 is transmission-connected to the winding shaft 2, a volute spring 304 is wound on the driving wheel 305, and the outer end of the volute spring 304 is fixedly connected to the outer circumferential surface of the energy storage wheel 303.

[0036] How it works

[0037] When the user pulls the gauze 4, the external force begins to be transmitted, the gauze 4 moves under the force, and the figure-eight winding drive assembly 3 connected to the starting end of the gauze 4 through the winding shaft 2 responds immediately, that is, when the vortex spring 304 is unwound at the driving wheel 305, the energy storage wheel 303 rewinds the vortex spring 304 accordingly; conversely: when the vortex spring 304 is rewound at the driving wheel 305, the energy storage wheel 303 unwinds the vortex spring 304 accordingly.

[0038] At the same time, the spring sheets 12 on both sides of the gauze 4 also stretch. The spring sheets 12 generate reverse pulling force in real time by virtue of their excellent elasticity to counteract the relaxation trend of the gauze 4 due to stretching, so that the gauze 4 always maintains a moderately tight state during the outward pulling process, ensuring the stability of the mesh shape of the gauze 4 and avoiding gaps for mosquitoes to enter.

[0039] When the screen 4 moves, the silent roller assembly 8 embedded in the edge of the plastic sheet 6 plays a key role. The silent roller assembly 8 continues to roll in the window frame slideway, converting the original sliding friction between the screen 4, the plastic sheet 6, and the track 11 into rolling friction. The rolling friction coefficient is extremely low, and the friction force is reduced by more than 80%, which greatly reduces the pulling resistance of the screen 4, allowing the screen 4 to smoothly follow the displacement direction of the user's force, and the silent roller assembly 8 can effectively suppress the generation of noise, achieving a nearly silent pulling effect.

[0040] Example 2

[0041] As attached Figure 1-4 As shown, the present invention provides a more stable coil spring hidden sand structure, comprising two groups of symmetrically distributed window frames 10, wherein tracks 11 are inserted in the window frames 10, and a plastic sheet 6 is slidably inserted between the two groups of tracks 11, and the plug-in end of the plastic sheet 6 is connected to a silent roller assembly 8 that slides with the track 11, and the bottom of the plastic sheet 6 is connected to a first adsorption block 7, and the tops of the two groups of window frames 10 are connected to a reel shell 1, and the bottoms of the two groups of window frames 10 are connected to a frame 13, and a reel shaft 2 is rotatably connected in the reel shell 1, and the two ends of the reel shaft 2 are respectively connected to an eight-shaped reel driving assembly 3 arranged on the outside of the reel shell 1, and the reel shaft 2 is connected to the plastic sheet 6 through a gauze 4, and the gauze 4 is slidably inserted in the track 11, and a spring sheet 12 corresponding to the gauze 4 is connected in the track 11, and a second adsorption block 14 corresponding to the first adsorption block 7 is connected to the top of the frame 13, and the second adsorption block 14 is adsorbed and connected to the first adsorption block 7.

[0042] The side of the gauze 4 is connected with a windproof sheet 5. The windproof sheet 5 can improve the sealing performance of the gauze 4, can effectively improve the working efficiency of the gauze 4, and can effectively improve the working effect of the gauze 4.

[0043] The outer side of the plastic sheet 6 is connected with an outwardly convex handle 9. The outwardly convex handle 9 can facilitate the user to pull the plastic sheet 6, and can effectively improve the working efficiency and working effect of the plastic sheet 6.

[0044] The plastic sheet 6 and the convex handle 9 are made in one piece. This arrangement can effectively improve the tightness between the plastic sheet 6 and the convex handle 9, and can effectively prevent the plastic sheet 6 and the convex handle 9 from breaking.

[0045] The first adsorption block 7 and the second adsorption block 14 are both bar-shaped magnetic products. The bar-shaped setting can effectively increase the adsorption area between the first adsorption block 7 and the second adsorption block 14; the setting of the magnetic product can facilitate the adsorption connection between the first adsorption block 7 and the second adsorption block 14, and effectively improve the connection efficiency between the first adsorption block 7 and the second adsorption block 14.

This arrangement can facilitate the rotation of the silent roller assembly 8 and can effectively improve the working efficiency and working effect of the silent roller assembly 8.

[0049] The roller 801 is a rubber product, and the bearing 803 is a low friction coefficient bearing. The rubber product has the advantages of excellent wear resistance and sound absorption performance, which can effectively increase the service life of the roller 801 and effectively improve the quiet effect of the roller 801 when in use; the low friction coefficient bearing generates very little noise during the rolling process, which effectively improves the quiet effect of the silent roller assembly 8 when in use.
