Description

Technical Field

[0001] This utility model belongs to the field of invisible screen technology, specifically relating to an invisible screen that prevents pets from tearing it. 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] In the existing technology, ordinary mesh cannot resist pets' scratches and bites, and is easily torn or derailed, resulting in the failure of protection. When the mesh is unfolded, it is only fixed by simple buckles, which are easy to dislodge under strong external impact. Furthermore, the mesh is prone to shifting when it hangs down, affecting the sealing performance and service life. Utility Model Content

[0004] The purpose of this utility model is to provide an invisible screen window that prevents pets from tearing and biting, aiming to solve the problems of ordinary screens in the prior art that cannot resist pets' scratches and bites, are easily torn or fall off the track, resulting in protection failure, rely only on simple buckles for fixation when the screen is unfolded, are easily dislodged under strong external impact, and are prone to shifting when the screen hangs down, affecting the sealing performance and service life.

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

[0006] An invisible window screen designed to prevent pets from tearing it, comprising:

[0007] The seat of honor;

[0008] Two connecting seats are fixedly connected to the lower end of the upper seat, and a lower seat is fixedly connected to the lower end of each of the two connecting seats. Limiting grooves are provided at the adjacent ends of the two connecting seats.

[0009] A mesh rotating shaft is rotatably connected to the inner surface of the upper seat. An invisible mesh is fixedly connected to the circumferential surface of the mesh rotating shaft, and a mounting base is fixedly connected to one end of the invisible mesh.

[0010] Two magnetic mesh pieces are respectively disposed at both ends of the invisible mesh; and two magnetic suction plates are disposed on the inner surface of each of the two limiting grooves; and

[0011] Two sets of buckling mechanisms are provided, both of which are located within the mounting base to secure the extended invisible mesh.

[0012] As a preferred embodiment of this utility model, two first springs are sleeved on the outer surface of the mesh rotating shaft, and two fixing sleeves are fixedly connected to the circumferential surface of the mesh rotating shaft and the inner wall of one side of the upper seat. The outer surfaces of the two first springs and the inner surfaces of the multiple fixing sleeves are movably connected respectively.

[0013] As a preferred embodiment of this utility model, each set of the buckling mechanism includes:

[0014] A sliding groove is provided at the lower end of the mounting base. A limiting plate and a sliding block are slidably connected to the inner surface of the sliding groove, and the outer surface of the limiting plate and the inner surface of the sliding block are fixedly connected.

[0015] A snap-fit ​​groove is provided at the upper end of the lower base. A snap-fit ​​block is slidably connected to the inner surface of the snap-fit ​​groove. The upper end of the snap-fit ​​block and the lower end of the sliding block are fixedly connected.

[0016] A limiting component is provided in the sliding groove to limit the sliding block.

[0017] A control component is disposed within the mounting base to control the sliding block to slide left and right.

[0018] As a preferred embodiment of this utility model, each set of limiting components includes:

[0019] Two parallel grooves are respectively formed on the inner walls of the two sides of the sliding groove. Parallel blocks are fixedly connected to both ends of the sliding block. The outer surfaces of the two parallel blocks and the inner surfaces of the two parallel grooves are slidably connected.

[0020] Two support bases are fixedly connected to the inner surfaces of two parallel slots, and a second spring is sleeved on the outer surface of each support base.

[0021] As a preferred embodiment of this utility model, each group of control components includes:

[0022] The control slot is located at the upper end of the mounting base. A control block is slidably connected to the inner surface of the control slot. The lower end of the control block and the upper end of the sliding block are fixedly connected. A telescopic sealing strip is fixedly connected to the inner surface of the control slot.

[0023] As a preferred embodiment of this utility model, both ends of the mounting base are fixedly connected to limit blocks, and the outer surfaces of the two limit blocks and the inner surfaces of the two limit grooves are slidably connected.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. In this solution, the invisible mesh is unfolded from the mesh shaft by manually pulling down the mounting base. Two limiting blocks slide vertically along the two limiting grooves of the connecting base. When the mounting base approaches the lower base, the mesh magnetic sheet and the two magnetic plates in the two limiting grooves generate a lateral attraction force to correct the position of the mesh. At the same time, the mounting base is pressed down to contact the lower base, and the snap-fit ​​block is guided by the inclined surface to slide into the snap-fit ​​groove. The sliding block moves laterally in the sliding groove to compress the second spring. After the snap-fit ​​block is fully inserted into the snap-fit ​​groove, the second spring releases its elasticity to push the sliding block back to its original position. At the same time, multiple magnetic blocks attract each other to strengthen the connection between the mounting base and the lower base, so that the mesh has both puncture resistance and tear resistance, effectively resisting pet scratches and bites, and preventing the mesh from falling off the track and causing the protection to fail. At the same time, the snap-fit ​​mechanism rigidly fixes the unfolded mesh, corrects the mesh position in real time, prevents local stress concentration caused by lateral displacement, and improves the sealing performance and service life of the mesh.

[0027] 2. In this solution, multiple magnetic blocks are used to enhance the magnetism during the snap-fit ​​process. When the mounting base approaches the lower base, the multiple magnetic blocks generate an adsorption force, which strengthens the fixing strength between the mounting base and the lower base.

[0040] 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.

[0041] Example 1

[0042] Please see Figure 1-10 The present invention provides the following technical solution:

[0043] An invisible window screen designed to prevent pets from tearing it, comprising:

[0044] Seat 1;

[0045] Two connecting seats 2 are fixedly connected to the lower end of the upper seat 1. The lower end of each of the two connecting seats 2 is fixedly connected to a lower seat 3. Limiting grooves 6 are provided at the close ends of the two connecting seats 2.

[0046] A mesh screen rotating shaft 8 is rotatably connected to the inner surface of the upper seat 1. An invisible mesh screen 4 is fixedly connected to the circumferential surface of the mesh screen rotating shaft 8, and a mounting base 5 is fixedly connected to one end of the invisible mesh screen 4.

[0047] Two magnetic mesh pieces 24 are respectively disposed at both ends of the invisible mesh 4; two magnetic suction plates 25 are disposed on the inner surface of each of the two limiting grooves 6; and

[0048] Two sets of locking mechanisms are installed within the mounting base 5 to secure the extended invisible mesh 4.

[0049] In a specific embodiment of this utility model, the upper seat 1 serves as the top load-bearing base of the screen window, supporting the system for the retraction or extension of the screen mesh. It is fixed to the upper end of the window frame by bolts. The internal bearing groove carries the rotational movement of the screen mesh shaft 8. Two connecting seats 2 connect the upper seat 1 and the lower seat 3, forming a vertical track frame. Aluminum alloy profiles are symmetrically arranged on both sides, and their inner limiting grooves 6 guide the mounting seat 5 to move up and down. The lower seat 3 provides a bottom fixing platform after the screen mesh is extended, and the snap-fit ​​groove 11 on the upper surface engages with the snap-fit ​​block 15. The two limiting grooves 6 constrain the movement trajectory of the mounting seat 5, while the T-shaped groove slides with the limiting block 7 to prevent the screen mesh from moving horizontally. The invisible mesh 4 is rotated or released by the mesh shaft 8, which is the core rotating component. The invisible mesh 4 has a core protective layer to prevent pets from tearing it, and it uses a double-layer composite structure with a 304 stainless steel fine mesh surface and a PET coating bottom layer, achieving tear and puncture resistance. The mounting base 5 is the movable end support mechanism at the bottom of the mesh, with an integrated snap-fit ​​mechanism. It slides vertically along the limiting groove 6 via the limiting block 7. The magnetic elements 24 assist in the positioning of the mesh, while two magnetic plates 25 enhance the lateral positioning of the mesh. The sliding groove 12 is a rectangular through groove at the bottom of the mounting base 5, with polished inner walls to reduce the coefficient of friction. The limiting plate... 13 is rigidly connected to the sliding block 14, and its width is greater than the opening of the sliding groove 12, forming a mechanical stop. It is a sliding carrier that transmits the control force through the sliding block 14. At the same time, the parallel block 20 moves linearly within the parallel groove 19. According to the mechanical latch of the locking block 15 that locks the position of the mesh, the parallel groove 19 ensures the linear movement of the sliding block 14. Meanwhile, the guide groove opened on the side wall of the sliding groove 12 eliminates the rotational degree of freedom of the sliding block 14. The support base 21 is the fixed base of the second spring 22, preventing the second spring 22 from becoming unstable. The second spring 22 provides the locking force of the locking block 15. The control block 17 is guided by the control groove 16. The rectangular hole at the top of the device moves in the same direction as the sliding block 14. The lower part of the control block 17 is fixedly connected to the sliding block 14. By pushing the control block 17, the lower fixed sliding block 14 is slid, so that the lower snap-fit ​​block 15 is inserted into the snap-fit ​​groove 11, completing the snap-fit ​​installation of the invisible mesh 4. This gives the mesh both puncture and tear resistance, effectively preventing pets from scratching and biting it, and avoiding the mesh from falling off the track and causing the protection to fail. At the same time, the snap-fit ​​mechanism rigidly fixes the unfolded mesh, corrects the mesh position in real time, prevents local stress concentration caused by lateral displacement, and improves the mesh's sealing performance and service life.

[0050] Please refer to the details. Figure 3 Two first springs 10 are sleeved on the outer surface of the mesh shaft 8. Two fixing sleeves 9 are fixedly connected to the circumferential surface of the mesh shaft 8 and the inner wall of one side of the upper seat 1. The outer surfaces of the two first springs 10 and the inner surfaces of the multiple fixing sleeves 9 are movably connected respectively.

[0051] In this embodiment: two first springs 10 provide the power for automatic retraction of the mesh and are sleeved on the outer surface of the mesh rotating shaft 8. The length of the mesh is controlled by the number of rotations of the first springs 10. At the same time, multiple fixing sleeves 9 limit the working position of the two first springs 10, ensuring that the two first springs 10 change when the mesh rotating shaft 8 rotates.

[0052] Please refer to the details. Figure 5 and Figure 7 Each set of latching mechanisms includes:

[0053] The sliding groove 12 is opened at the lower end of the mounting base 5. The inner surface of the sliding groove 12 is slidably connected to the limiting plate 13 and the sliding block 14. The outer surface of the limiting plate 13 and the inner surface of the sliding block 14 are fixedly connected.

[0054] The snap-fit ​​groove 11 is opened at the upper end of the lower base 3. The snap-fit ​​block 15 is slidably connected to the inner surface of the snap-fit ​​groove 11. The upper end of the snap-fit ​​block 15 is fixedly connected to the lower end of the sliding block 14.

[0055] A limiting component is provided in the sliding groove 12 to limit the sliding block 14.

[0056] The control component is located within the mounting base 5 to control the sliding block 14 to slide left and right.

[0057] In this embodiment: a rectangular through groove 12 is formed at the bottom of the mounting base 5, and the inner wall is polished to reduce the coefficient of friction. The limiting plate 13 is rigidly connected to the sliding block 14, and its width is greater than the opening of the sliding groove 12, forming a mechanical stop. The sliding block 14 is a sliding carrier that transmits the control force. At the same time, the parallel block 20 moves linearly in the parallel groove 19. According to the mechanical latch of the locking block 15 that locks the position of the mesh, the parallel groove 19 ensures the linear movement of the sliding block 14. At the same time, the guide groove formed on the side wall of the sliding groove 12 eliminates the rotation of the sliding block 14. The second spring 22 is fixed to the support base 21 to prevent it from becoming unstable. The second spring 22 provides locking force to the snap-fit ​​block 15. The control block 17 is guided to move by the control groove 16. The rectangular hole at the top is aligned with the moving direction of the sliding block 14. The lower part of the control block 17 is fixedly connected to the sliding block 14. By pushing the control block 17, the lower fixed sliding block 14 is slid, so that the lower snap-fit ​​block 15 can be inserted into the snap-fit ​​groove 11 to complete the snap-fit ​​installation of the invisible mesh 4.

[0058] Please refer to the details. Figure 7 Each set of limit components includes:

[0059] Two parallel grooves 19 are respectively opened on the inner walls of the two sides of the sliding groove 12. Parallel blocks 20 are fixedly connected to both ends of the sliding block 14. The outer surfaces of the two parallel blocks 20 and the inner surfaces of the two parallel grooves 19 are slidably connected.

[0060] Two support seats 21 are fixedly connected to the inner surfaces of two parallel grooves 19, and a second spring 22 is sleeved on the outer surface of each support seat 21.

[0061] In this embodiment: the parallel groove 19 ensures the linear movement of the sliding block 14, while the guide groove opened on the side wall of the sliding groove 12 and the parallel block 20 eliminate the rotational degree of freedom of the sliding block 14. The support base 21 is the fixed base of the second spring 22 to prevent the second spring 22 from becoming unstable. The second spring 22 provides the locking force of the snap-fit ​​block 15.

[0062] Please refer to the details. Figure 5 Each control unit includes:

[0063] The control groove 16 is located at the upper end of the mounting base 5. The inner surface of the control groove 16 is slidably connected to the control block 17. The lower end of the control block 17 is fixedly connected to the upper end of the sliding block 14. The inner surface of the control groove 16 is fixedly connected to the telescopic sealing strip 23.

[0064] In this embodiment: the control block 17 is guided to move according to the control groove 16. The rectangular hole at the top is aligned with the moving direction of the sliding block 14. The lower part of the control block 17 is fixedly connected to the sliding block 14. The sliding block 14 at the lower end is controlled to slide by pushing the control block 17, so that the lower snap-fit ​​block 15 can be inserted into the snap-fit ​​groove 11 to complete the snap-fit ​​installation of the invisible mesh 4. The telescopic sealing strip 23 has the function of dustproof and waterproof sealing, and can also shrink in length when squeezed.

[0065] Please refer to the details. Figure 9 Limiting blocks 7 are fixedly connected to both ends of the mounting base 5, and the outer surfaces of the two limiting blocks 7 and the inner surfaces of the two limiting grooves 6 are slidably connected.

[0066] In this embodiment: the movement trajectory of the mounting base 5 is constrained by two limiting grooves 6 to prevent the mounting base 5 from derailing. At the same time, the T-shaped groove slides with the limiting block 7 to prevent the mesh from shifting laterally.

[0067] Please refer to the details. Figure 5 and Figure 10 Two magnetic blocks 26 are provided at the upper end of the lower seat 3 and the lower end of the mounting seat 5, and cover plates 18 are slidably connected to the outer surfaces of the two control blocks 17.

[0068] In this embodiment: the magnetic attraction is enhanced by multiple magnetic blocks 26 when the mounting base 5 approaches the lower base 3. The magnetic attraction between the multiple magnetic blocks 26 is strengthened, and the fixing strength between the mounting base 5 and the lower base 3 is enhanced. The cover plate 18 limits the connection of the two control blocks 17, and at the same time, it is convenient for the operator to press the two control blocks 17 to slide.

[0069] The working principle and usage process of this utility model are as follows: First, manually pull down the mounting base 5 to cause the invisible mesh 4 to unfold from the mesh rotating shaft 8. The two limiting blocks 7 slide vertically along the two limiting grooves 6 of the connecting base 2. When the mounting base 5 approaches the lower base 3, the mesh magnetic sheet 24 and the two magnetic suction plates 25 in the two limiting grooves 6 generate a lateral adsorption force to correct the position of the mesh. The mounting base 5 continues to press down until it contacts the lower base 3. The snap-fit ​​block 15 is guided by the inclined surface to slide into the snap-fit ​​groove 11. The sliding block 14 moves laterally in the sliding groove 12 to compress the second spring 22. After the snap-fit ​​block 15 is fully inserted into the snap-fit ​​groove 11, the second spring 22 releases its elastic force to push the sliding block 14 into the groove 12. The moving block 14 resets, and at the same time, multiple magnetic blocks 26 attract each other to strengthen the connection between the mounting base 5 and the lower base 3. During the screen window retrieval stage, the finger pushes the control block 17, which drives the sliding block 14 to slide laterally along the parallel groove 19. The parallel block 20 compresses the second spring 22. Under the action of force, the locking block 15 exits the locking groove 11. At the moment the mounting base 5 moves upward, the attraction force of multiple magnetic blocks 26 decreases, the first spring 10 releases the pre-tightening torque, and drives the screen screen shaft 8 to rotate and retract the invisible screen screen 4. The limiting block 7 slides upward along the limiting groove 6 to guide the mounting base 5 to reach the bottom of the upper base 1, completing the retrieval of the invisible screen screen 4.

[0070] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
