Description

Technical Field

[0001] This utility model belongs to the field of folding screen technology, specifically relating to a multi-segment hovering and positioning protective screen. Background Technology

[0002] Existing folding screen technology is mainly based on a multi-section linkage folding structure, which connects multiple window segments through pivots or hinges to achieve push-pull opening and closing, and is widely used in door and window ventilation and protection. Its typical structure includes an outer frame, folding window body, sliding rail and locking device. The folding method is mostly horizontal or vertical push-pull, relying on pulleys or sliders to guide the sliding within the rail to realize the opening and closing of the screen.

[0003] Authorized publication number "CN216741313U" discloses a partially foldable screen window. The foldable screen window comprises a screen window frame formed by screen window profiles, characterized by: further including a folding part and a rotating connecting assembly connecting the folding part and the screen window profiles. The rotating connecting assembly includes a connecting body with symmetrically arranged openings in the pivot cavities. Both the screen window profiles and the folding part are provided with pivots embedded in the pivot cavities. The connecting body also has a locking part, and cover plates are provided at both ends of the connecting body and connected to the locking part by fasteners. This utility model designs a foldable screen window with a novel structure, good integrity and aesthetics, and the folding part and rotating connecting assembly of this application have a certain damping, preventing wobbling.

[0004] The aforementioned new type connects the folding section and the screen window through a rotating connecting component, improving the overall integrity and aesthetics of the screen window. Folding screen windows that cannot be hovered and positioned have the defect of not being able to stay stably in any position during use, causing users to only be able to fully open or fully close them, lacking flexibility in use. Especially when partial ventilation is needed or when coordinating with curtains and furniture layout, it is difficult to accurately control the opening and closing range, and they are prone to sliding due to wind or vibration, affecting the safety and experience of use. At the same time, the lack of an effective locking mechanism also reduces the overall stability and wind pressure resistance of the screen window. Long-term use can easily cause wear on the slide rails and loosening of the structure, affecting the product's lifespan. Utility Model Content

[0047] Please refer to the details. Figures 1-6 The fixing assembly includes a spring groove 9, a spring push plate 10, a pull-out rod 11, a fixing spring 12, a pull-out block 13, and a fixing insert 14. The spring groove 9 is opened at one end of the limiting slide rod 7. The spring push plate 10 is slidably connected in the spring groove 9. The pull-out rod 11 is fixedly connected to one end of the spring groove 9. The fixing spring 12 is fixedly connected to one inner wall of the spring groove 9 and one end of the spring push plate 10. The pull-out block 13 is fixedly connected to one end of the pull-out rod 11. The fixing insert 14 is fixedly connected to one end of the pull-out block 13 and matches the fixing slot 8.

[0048] In this embodiment: when it is necessary to fix the multi-segment suspended positioning protective screen window at a fixed point, push the upper folding window 2 and the lower folding window 3 to unfold to the required position. At this time, the limiting slide rod 7 slides along the limiting slide groove 5 and drives the fixing component at its end to move synchronously. When the fixing block 14 approaches the fixing slot 8 on the side of the multi-segment screen window frame 1, manually pull out the pull-out block 13 to drive the pull-out rod 11 and the spring push plate 10 in the spring groove 9 to move and compress the fixing spring 12. After the fixing block 14 is aligned with the fixing slot 8, release the pull-out block 13. Under the action of the elastic restoring force of the fixing spring 12, the spring push plate 10 pushes the pull-out rod 11 forward, so that the fixing block 14 can be smoothly inserted into the fixing slot 8 to achieve stable positioning of the screen window. When it is necessary to fold up the screen window, pull out the pull-out block 13 again to make the fixing block 14 disengage from the fixing slot 8, so that the upper folding window 2 and the lower folding window 3 can be folded and folded up freely.

[0049] Please refer to the details. Figures 1-6 Rubber pads 15 are provided on both sides of the pull-out block 13.

[0050] In this embodiment, rubber pads 15 are provided on both sides of the pull-out block 13. The rubber pads 15 are fixed to the sides of the pull-out block 13 by adhesive or embedding. Their function is to increase the friction between the user's fingers and the pull-out block 13, prevent slippage during operation, and improve grip comfort and ease of operation.

[0051] Please refer to the details. Figures 1-6 The inner side wall of the fixed slot 8 is provided with a guide chamfer 16, which is used to guide the fixed plug 14 to be inserted into the fixed slot 8.

[0052] In this embodiment, a guide chamfer 16 is provided on the inner side wall of the fixed slot 8. The guide chamfer 16 is located at the entrance of the fixed slot 8 and has an inclined transition structure. When the screen is pulled to bring the fixed plug 14 close to the fixed slot 8, the guide chamfer 16 can guide and correct the insertion direction of the fixed plug 14. Even if there is a slight deviation between the two at the initial docking, the chamfer can guide the fixed plug 14 to slide smoothly into the fixed slot 8, effectively avoiding jamming or insertion failure caused by misalignment.

[0053] Please refer to the details. Figures 1-6 A limiting slider 17 is fixedly connected to the outer surface of the limiting slide rod 7, and the limiting slider 17 slides within the limiting slide groove 5.

[0054] In this embodiment: the outer surface of the limiting slide rod 7 is fixedly connected to the limiting slider 17, and the limiting slider 17 is embedded in and slides along the limiting grooves 5 opened on both sides of the multi-segment screen frame 1. This structural design enhances the stability and guiding accuracy of the limiting slide rod 7 during the sliding process, and effectively prevents it from deflecting or shaking during the movement. The cooperation between the limiting slider 17 and the limiting groove 5 constrains the movement trajectory of the lower folding window 3 and the overall folding structure, ensuring that the upper folding window 2 and the lower folding window 3 maintain synchronous and stable operation during the unfolding or closing process.

[0055] Please refer to the details. Figures 1-6 Two clamping pads 18 are fixedly connected to the circumferential surface of the limiting slide bar 7, and the two clamping pads 18 are fitted on both sides of the lower folding window 3.

[0056] In this embodiment, two clamping pads 18 are fixedly connected to the circumferential surface of the limiting slide rod 7. The two clamping pads 18 are located on both sides of the lower folding window 3 and are fitted against its outer wall. This structure enhances the connection stability between the limiting slide rod 7 and the lower folding window 3 through the clamping pads 18, effectively improving the assembly accuracy and anti-shaking ability of the overall structure. The clamping pads 18 are made of elastic wear-resistant material, which can provide appropriate pre-tightening force without affecting the normal rotation and sliding of the limiting slide rod 7, reducing the loosening caused by vibration or wind pressure during use.

[0057] The working principle and usage process of this utility model are as follows: During installation, the multi-section screen frame 1 is fixed to the door and window opening. During use, the upper folding window 2 is pushed to unfold around the pivot, which drives the lower folding window 3 to unfold synchronously. The limiting slide rod 7 rotates in the pivot groove 6 and slides along the limiting slide groove 5. The limiting slider 17 on its outer surface is guided in the limiting slide groove 5 to ensure smooth movement. Two clamping pads 18 are fitted on both sides of the lower folding window 3 to enhance connection stability. When the screen is unfolded to the desired position, the fixing component moves with the limiting slide rod 7 to the vicinity of the fixing slot 8. At this time, the pull-out block 13 is manually pulled, which drives the spring push plate 10 to compress the fixing spring 12 through the pull-out rod 11, so that the fixing insert 14 is aligned with the fixing slot 8. After releasing the pull-out block 13, the fixing is completed. Spring 12 releases its elastic force to push spring push plate 10 and pull-out block 13 forward, allowing fixed insert block 14 to be inserted into fixed slot 8 to complete locking. During the process, the guide chamfer 16 on the inner wall of fixed slot 8 guides fixed insert block 14 to be smoothly inserted, improving the alignment success rate. Rubber pads 15 on both sides of pull-out block 13 increase friction and facilitate operation. When the screen window needs to be retracted, pull-out block 13 is pulled again to disengage fixed insert block 14 from fixed slot 8, allowing the upper folding window 2 and lower folding window 3 to be folded to one side, saving space. The entire device achieves flexible opening and closing through multi-segment folding structure and limit sliding cooperation, and can be suspended and positioned at any position by combining with fixed components. It has a compact structure, is easy to operate, and runs smoothly, making it suitable for various door and window protection scenarios.
