Description

Technical Field

[0001] This utility model belongs to the field of invisible screen technology, specifically relating to an invisible screen component made of composite material that resists ultraviolet radiation. Background Technology

[0002] Retractable screens are a common type of window screen. Through a specific process, the screen mesh is wound onto a roller and placed inside a screen box. The roller serves as the core of the screen mesh. One end of the roller is connected to a bearing on the end cap of the screen box via a torsion spring, and the other end is connected to a bearing on the end cap via a rotating wheel. In use, the screen mesh is manually pulled out to a preset position and secured with fasteners. When not in use, the connection between the screen mesh and the fasteners is released, and the screen mesh is rewound onto the core roller and returned to the screen box under the action of the torsion spring.

[0003] Traditional window screens mostly use ordinary fiberglass mesh, which has an ultraviolet blocking rate of less than 30%. They are prone to aging and cracking after long-term use, and cannot meet the needs of high-radiation areas. At the same time, the mechanical buckle has poor reliability, and the elasticity fails after repeated stretching, causing the mesh to roll back unexpectedly. There is no anti-accidental touch design, and external impact can easily trigger the unlocking. Utility Model Content

It aims to solve the problems of traditional screen windows in the prior art, which mostly use ordinary glass fiber mesh, with an ultraviolet blocking rate of less than 30%, are prone to aging and cracking after long-term use, and cannot meet the needs of high radiation areas. At the same time, the mechanical buckle has poor reliability, and the elasticity fails after repeated stretching, causing the mesh to roll back unexpectedly. There is no anti-accidental touch design, and external force collisions can easily trigger the unlocking.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite material invisible screen component resistant to ultraviolet radiation, comprising:

[0007] Top seat;

[0008] Two connecting seats are fixedly connected to the lower end of the top seat, and a base is fixedly connected to the lower end of each of the two connecting seats. Multiple connecting posts are fixedly connected to the upper end of the base.

[0009] A rotating shaft is rotatably connected to the inner walls of both sides of the top seat, and a composite material invisible mesh is fixedly connected to the outer surface of the rotating shaft.

[0010] A fixing base, wherein the fixing base is fixedly connected to one end of the composite material invisible mesh, and elastic sheets are fixedly connected to both ends of the composite material invisible mesh; and

[0011] A snap-fit ​​mechanism is provided inside the base to secure the telescopic composite invisible mesh.

[0012] As a preferred embodiment of this utility model, the latching mechanism includes:

[0013] The movable groove is located at one end of the fixed base, and the connecting base has a snap-fit ​​groove at one end. Snap-fit ​​blocks are slidably connected to the inner surfaces of both the movable groove and the snap-fit ​​groove, and a limit plate is fixedly connected to one end of each snap-fit ​​block.

[0014] Two sliding grooves are provided, both of which are formed on the inner walls of the movable groove. Sliding blocks are slidably connected to the inner surfaces of both sliding grooves. The adjacent ends of the two sliding blocks are fixedly connected to the two ends of the snap-fit ​​block.

[0015] A limiting component is provided in the movable groove to support the sliding buckle block;

[0016] A control component is disposed within a fixed base to control the sliding of the latch block.

[0017] As a preferred embodiment of this utility model, the limiting component includes:

[0018] Two limiting seats are fixedly connected to the inner surfaces of two sliding grooves, and a first spring is sleeved on the outer surface of each of the two limiting seats. The outer surfaces of the two first springs and the outer surfaces of the two sliding blocks are fixedly connected.

[0019] As a preferred embodiment of this utility model, the control component includes:

[0020] The control slot is located at one end of the fixed base. A control block is slidably connected to the inner surface of the control slot. One end of the control block is fixedly connected to one end of the snap-fit ​​block. A telescopic sealing sheet is provided on the inner surface of the control slot.

[0021] In a preferred embodiment of this utility model, two hook seats are fixedly connected to the outer surface of the rotating shaft and the inner wall of one side of the top seat, and two second springs are fixedly connected to the inner surfaces of the plurality of hook seats respectively, and two support seats are provided on the outer surface of the rotating shaft.

[0022] As a preferred embodiment of this utility model, a limiting groove is provided at one end of each of the two connecting seats, and a limiting block is slidably connected to the inner surface of each of the two limiting grooves.

[0023] As a preferred embodiment of this utility model, the upper end of the base and the lower end of the fixing seat are both provided with mounting grooves, and magnetic blocks are provided on the inner surface of the plurality of mounting grooves.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. In this solution, by pulling the fixed base downwards, the composite material invisible mesh is released from the rotating shaft. The elastic sheet provides lateral tension to keep the mesh flat. When the fixed base approaches the base, the buckle block extends out of the movable groove under the push of the first spring. The sliding block is guided along the sliding groove to align the buckle block with the buckle groove of the connecting base. At the moment the fixed base contacts the base, the buckle block inserts into the buckle groove, completing the locking between the fixed base and the base. The composite material invisible mesh contains a nano-TiO2 coating and a polyester fiber substrate, thereby blocking ultraviolet rays and delaying the aging of the mesh. The double locking mechanism ensures mechanical interlocking and locking, avoiding the phenomenon of elastic failure after repeated stretching, which could lead to accidental rewinding of the mesh. At the same time, an anti-accidental touch design is designed to prevent external force collisions from triggering unlocking.

[0026] 2. In this solution, multiple mounting slots are symmetrically opened on the upper end of the base and the lower end of the fixing seat, and the mounting positions of multiple magnetic blocks are precisely aligned. At the same time, multiple magnetic blocks are embedded in multiple mounting slots to generate magnetic attraction, which helps the fixing seat and the base to fit tightly together and enhances locking stability.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] Please see Figure 1-7 The present invention provides the following technical solution:

[0039] A composite material invisible screen component resistant to ultraviolet radiation, comprising:

[0040] Top seat 1;

[0041] Two connecting seats 2 are fixedly connected to the lower end of the top seat 1. The lower end of each connecting seat 2 is fixedly connected to a base 3. The upper end of the base 3 is fixedly connected to multiple connecting posts 26.

[0042] Rotating shaft 13 is rotatably connected to the inner walls of both sides of the top seat 1, and a composite material invisible mesh 4 is fixedly connected to the outer surface of the rotating shaft 13.

[0043] Fixing base 5 is fixedly connected to one end of the composite material invisible mesh 4, and elastic sheets 12 are fixedly connected to both ends of the composite material invisible mesh 4; and

[0044] The buckle mechanism is located inside the base 3 to secure the telescopic composite invisible mesh 4.

[0045] In a specific embodiment of this utility model, the top seat 1 serves as the top load-bearing foundation of the component, fixed to the upper end of the window frame, and also provides a mounting point for the rotating shaft 13 to ensure the stability of the vertical expansion and contraction of the screen. Two connecting seats 2 vertically connect the top seat 1 and the base 3, transmitting structural loads, and have built-in limiting grooves 11 to guide the sliding trajectory of the fixed seat 5. The base 3 supports the bottom of the component and is fixed to the lower end of the window frame. Multiple connecting columns 26 enhance the structural strength, prevent deformation, improve the compressive strength of the base 3, disperse external impacts, and maintain the parallel alignment of the base 3 and the top seat 1. The rotating shaft 13 is rotatably mounted on the inner walls of both sides of the top seat 1 to wind or release the composite material invisible screen 4, realizing the screen's expansion and contraction function. The composite material invisible screen 4 contains a nano-TiO2 coating and polyester. The fiber substrate blocks ultraviolet rays, delays the aging of the mesh, and achieves an anti-ultraviolet radiation effect. Simultaneously, one end of the composite invisible mesh 4 is fixed to the rotating shaft 13, and the other end is connected to the fixing base 5. The fixing base 5 serves as the force-bearing end for mesh stretching; the user pulls the mesh, and a built-in buckle mechanism, in conjunction with the base 3, locks the mesh position. Two elastic pieces 12 are attached to the edges of the mesh to provide lateral tension, eliminating wrinkles and ensuring a flat surface when unfolded. A movable groove 20 is located at the end of the fixing base 5, accommodating the sliding space of the buckle block 23. A buckle groove 21 is located on the side of the connecting base 2, aligning with the movable groove 20 to form an interlocking channel. The buckle block 23 slides bidirectionally within the movable groove 20 and the buckle groove 21, physically locking the mesh position. To resist the rewinding force of the rotating shaft 13, the limiting plate 22 is fixed to the end of the latching block 23, limiting its sliding stroke and preventing the latching block 23 from dislodging from the movable groove 20. Two sliding grooves 24 are located on the inner walls of both sides of the movable groove 20, providing guide tracks for the sliding block 25. At the same time, the two sliding blocks 25 are connected to both sides of the latching block 23 to ensure that its linear movement does not deviate. Two limiting seats 17 are fixed to the inner walls of the sliding grooves 24, serving as mounting bases for the first springs 14. At the same time, the two first springs 14 are sleeved on the outside of the limiting seats 17, with both ends connected to the sliding blocks 25, providing elastic restoring force so that the latching block 23 automatically returns to the locked position. The control groove 6 is opened on the surface of the fixed base 5 to accommodate the sliding space of the control block 7. The control block 7 is exposed on the fixed base 5 for the user to press and operate. The direct linkage buckle block 23 transmits pressure to unlock the device. The telescopic sealing sheet 8 covers the opening of the control groove 6, preventing dust and foreign objects. The elastic material allows the control block 7 to extend and retract. The composite material invisible mesh 4 contains a nano-TiO2 coating and a polyester fiber substrate, thereby blocking ultraviolet rays and delaying the aging of the mesh. The double locking mechanism ensures mechanical engagement and avoids the loss of elasticity after repeated stretching, which could lead to accidental rewinding of the mesh. It also has an anti-accidental touch design to prevent external force from triggering the unlocking. It should be noted that the specific type of composite material invisible mesh 4 used is to be selected by those skilled in the art. The above-mentioned composite material invisible mesh 4 is all existing technology and will not be elaborated on in this solution.

[0046] Please refer to the details. Figure 6 The locking mechanism includes:

[0047] The movable groove 20 is opened at one end of the fixed base 5, and the connecting base 2 has a snap-fit ​​groove 21 at one end. The inner surfaces of the movable groove 20 and the snap-fit ​​groove 21 are slidably connected with snap-fit ​​blocks 23, and one end of the snap-fit ​​block 23 is fixedly connected to a limit plate 22.

[0048] Two sliding grooves 24 are provided on the inner walls of both sides of the movable groove 20. Sliding blocks 25 are slidably connected to the inner surfaces of the two sliding grooves 24. The close ends of the two sliding blocks 25 are fixedly connected to the two sides of the buckle block 23 respectively.

[0049] A limiting component is provided within the movable groove 20 to support the sliding latch block 23.

[0050] The control component is located within the fixed base 5 to control the sliding of the latch block 23.

[0051] In this embodiment: a movable groove 20 is formed at the end of the fixed base 5 to accommodate the sliding space of the snap-fit ​​block 23. A snap-fit ​​groove 21 is formed on the side of the connecting base 2, aligned with the movable groove 20 to form an engagement channel. The snap-fit ​​block 23 slides bidirectionally within the movable groove 20 and the snap-fit ​​groove 21, physically locking the position of the mesh and resisting the rewinding force of the rotating shaft 13. A limiting plate 22 is fixed to the end of the snap-fit ​​block 23 to limit its sliding stroke and prevent the snap-fit ​​block 23 from coming out of the movable groove 20. Two sliding grooves 24 are located on the inner walls of both sides of the movable groove 20 to provide guide tracks for the sliding blocks 25. At the same time, the two sliding blocks 25 connect the two sides of the snap-fit ​​block 23. To ensure its linear motion without deviation, two limiting seats 17 are fixed to the inner wall of the sliding groove 24, serving as the mounting base for the first spring 14. At the same time, the two first springs 14 are sleeved on the outside of the limiting seats 17, with sliding blocks 25 connected at both ends to provide elastic restoring force, so that the buckle block 23 automatically resets to the locked position. The control groove 6 is opened on the surface of the fixed seat 5 to accommodate the sliding space of the control block 7. The control block 7 is exposed on the fixed seat 5 for the user to press and operate, directly linking the buckle block 23 to transmit pressing force to release the lock. The telescopic sealing sheet 8 covers the opening of the control groove 6 to prevent dust and foreign objects, and the elastic material allows the control block 7 to telescopically move.

[0052] Please refer to the details. Figure 6 The limiting components include:

[0053] Two limiting seats 17 are fixedly connected to the inner surfaces of two sliding grooves 24 respectively. The outer surfaces of the two limiting seats 17 are each fitted with a first spring 14. The outer surfaces of the two first springs 14 and the outer surfaces of the two sliding blocks 25 are fixedly connected respectively.

[0054] In this embodiment: two limiting seats 17 are fixed to the inner wall of the sliding groove 24 as the mounting base of the first spring 14. At the same time, the two first springs 14 are sleeved on the outside of the limiting seats 17 and connected to the sliding blocks 25 at both ends to provide elastic restoring force, so that the buckle block 23 automatically resets to the locked position.

[0055] Please refer to the details. Figure 3 The control components include:

[0056] The control groove 6 is located at one end of the fixed base 5. The inner surface of the control groove 6 is slidably connected to the control block 7. One end of the control block 7 is fixedly connected to one end of the snap block 23. The inner surface of the control groove 6 is provided with a telescopic sealing sheet 8.

[0057] In this embodiment: the control groove 6 is opened on the surface of the fixed base 5 to accommodate the sliding space of the control block 7. The control block 7 is exposed on the fixed base 5 for the user to press and operate. It directly links the buckle block 23 to transmit the pressing force to release the lock. The telescopic sealing sheet 8 covers the opening of the control groove 6 to prevent dust and foreign objects. The elastic material allows the control block 7 to telescopically move.

[0058] Please refer to the details. Figure 5 Two hook seats 19 are fixedly connected to the outer surface of the rotating shaft 13 and the inner wall of one side of the top seat 1. Two second springs 16 are fixedly connected to the inner surface of the multiple hook seats 19 respectively. Two support seats 18 are provided on the outer surface of the rotating shaft 13.

[0059] In this embodiment: two of the four hook seats 19 are fixed to the inner wall of the top seat 1 and two are fixed to the surface of the rotating shaft 13, thus serving as anchor points for the two second springs 16. At the same time, the two second springs 16 connect the top seat 1 and the four hook seats 19 of the rotating shaft 13, providing rotational elasticity so that the yarn can be automatically rolled up. The two support seats 18 are installed on the outer surface of the rotating shaft 13 to reduce rotational friction.

[0060] Please refer to the details. Figure 7 Each of the two connecting seats 2 has a limiting groove 11 at one end, and the inner surfaces of the two limiting grooves 11 are slidably connected to limiting blocks 15. The adjacent ends of the two limiting blocks 15 are fixedly connected to the two sides of the fixed seat 5 respectively.

[0061] In this embodiment, two limiting grooves 11 are formed on the side of the connecting seat 2 to serve as sliding tracks for the limiting blocks 15. At the same time, one end of the two limiting blocks 15 is fixed to both sides of the fixed seat 5, and the other end slides in the limiting grooves 11, which constrains the vertical movement trajectory of the fixed seat 5 and prevents lateral swaying.

[0062] Please refer to the details. Figure 7The upper end of the base 3 and the lower end of the fixed seat 5 are both provided with mounting grooves 9, and magnetic blocks 10 are provided on the inner surface of multiple mounting grooves 9.

[0063] In this embodiment: multiple mounting slots 9 are symmetrically opened on the upper end of the base 3 and the lower end of the fixing seat 5, and the mounting positions of multiple magnetic blocks 10 are precisely aligned. At the same time, the multiple magnetic blocks 10 are embedded in the multiple mounting slots 9 to generate magnetic attraction, which helps the fixing seat 5 to fit tightly with the base 3 and enhances the locking stability.

[0064] The working principle and usage process of this utility model are as follows: First, the user pulls the fixed seat 5 downward. The fixed seat 5 slides vertically along the limiting groove 11 of the connecting seat 2 through the limiting block 15 to ensure that the trajectory is not deviated. The composite material invisible mesh 4 is released from the rotating shaft 13. The elastic sheet 12 provides lateral tension to keep the mesh flat. When the fixed seat 5 approaches the base 3, the buckle block 23 extends out in the movable groove 20 under the push of the first spring 14. The sliding block 25 guides along the sliding groove 24 so that the buckle block 23 aligns with the buckle groove 21 of the connecting seat 2. At the moment when the fixed seat 5 contacts the base 3, the buckle block 23 inserts into the buckle groove 21. The limiting plate 22 prevents excessive displacement. The magnetic block 10 adsorbs the fixed seat 5 and the base 3 in the mounting groove 9 to help enhance the locking.
