Description

Technical Field

[0001] This utility model relates to the field of screen technology, specifically a screen that is easy to disassemble and clean. Background Technology

[0002] Screens are common ventilation and insect-proofing devices in buildings and are widely used in various doors and windows. Existing screens typically consist of a fixed frame and an installation frame, where the installation frame is used to fix the screen mesh, and the fixed frame is connected to the window frame.

[0003] Currently, the fixed frame and the mounting frame are mostly connected by a traditional hinge structure and fixed with screws.

[0004] However, this connection method has the following drawbacks in practical use:

[0005] 1. Inconvenient disassembly: When it is necessary to clean or maintain the screen window, the screws that fix the hinge must be removed, which is cumbersome and time-consuming.

[0006] 2. High dependence on tools: Disassembly and installation require tools such as screwdrivers. If the tools are not complete or are lost, the operation cannot be completed.

[0007] 3. Prone to loosening with long-term use: Screws are prone to stripping or loosening after repeated disassembly, affecting the stability and service life of the screen.

[0008] Therefore, we propose a window screen that is easy to disassemble and clean. Utility Model Content

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] This embodiment is a window screen that is easy to disassemble and clean.

[0030] like Figure 1-4As shown, the system includes a fixed frame 1 and an installation frame 2. A screen mesh 3 is installed inside the installation frame 2. A limit lock 4 is installed on one outer surface of the installation frame 2. The upper and lower ends of one outer surface of the installation frame 2 are connected to the upper and lower ends of one outer surface of the fixed frame 1 by a hinge structure 5. There are two sets of hinge structures 5. The hinge structure 5 includes a first connecting structure 6 and a second connecting structure 7. The second connecting structure 7 includes a first fixing block 8, a fixing ring 9, a rotating ring 10, and a first internal hexagonal groove 11. The first connecting structure 6 includes a second fixing block 12, a connecting block 13, a connecting shaft 14, a second internal hexagonal groove 15, an internal hexagonal limit shaft 16, and a compression spring 19. The first fixing block 8 is fixed to the fixed frame 1 by bolts, and the second fixing block 12 is fixed to the installation frame 2 by bolts.

[0031] In a set of second connecting structures 7, there are two sets of fixed rings 9, rotating rings 10, and first hexagonal sockets 11. The two sets of fixed rings 9 are fixedly installed at the upper and lower ends of one side of the outer surface of the first fixed block 8. The rotating ring 10 is installed inside the fixed ring 9. The first hexagonal socket 11 is formed on the upper outer surface of the rotating ring 10 and extends to the lower outer surface of the rotating ring 10. A bearing is provided between the rotating ring 10 and the fixed ring 9, and the rotating ring 10 is rotatably connected to the fixed ring 9 through the bearing. The connecting block 13 is fixedly installed between the middle of one side of the outer surface of the second fixed block 12 and one side of the outer surface of the connecting shaft 14. In a set of first connecting structures 6, there are two sets of second hexagonal sockets 15, hexagonal socket limiting shafts 16, and compression springs 19. The two sets of second hexagonal sockets 15 are formed on the connecting shaft 14. On the outer surfaces of the upper and lower ends, the compression spring 19 is located in the second internal hexagonal groove 15. The compression spring 19 is fixed between the outer surface of one end of the internal hexagonal limiting shaft 16 and one end of the second internal hexagonal groove 15. The outer wall of the internal hexagonal limiting shaft 16 and the second internal hexagonal groove 15 are slidably connected. The lower outer surface of the internal hexagonal limiting shaft 16 is elastically connected to the bottom of the second internal hexagonal groove 15 through the compression spring 19. The connecting shaft 14 is located between the two sets of fixing rings 9 in the second connecting structure 7. The upper outer wall of the internal hexagonal limiting shaft 16 is inserted into the first internal hexagonal groove 11. A first pin hole 17 is opened at the end of the outer surface of one side of the internal hexagonal limiting shaft 16 away from the compression spring 19. The upper and lower ends of the outer surface of one side of the connecting shaft 14 are fitted with second pin holes 18, and one end of the second pin hole 18 penetrates to one side of the second internal hexagonal groove 15.

[0032] It should be noted that this utility model is a screen window that is easy to disassemble and clean. The fixed frame 1, mounting frame 2, screen mesh 3 and limiting lock 4 described in the text are all existing technologies and can be effectively known to those skilled in the art. Specific details will not be elaborated further. A hinge structure 5 is provided, connecting the mounting frame 2 and the fixed frame 1. The second connecting structure 7 is fixed to the fixed frame 1, and the first connecting structure 6 is fixed to the mounting frame 2. During assembly, by pressing the internal hexagonal limiting shafts 16 at both ends of the connecting shaft 14, the internal hexagonal limiting shafts 16 press against the compression spring 19 along the second internal hexagonal groove 15, causing the internal hexagonal limiting shafts 16 to enter the second internal hexagonal groove 15. Then, the connecting shaft 14 is inserted between the two sets of fixing rings 9. Due to the reaction force of the compression spring 19, the upper part of the internal hexagonal limiting shaft 16 is inserted... The screen is inserted into the first internal hexagonal slot 11, and when the mounting frame 2 is flipped, the rotating ring 10 can be rotated by the internal hexagonal limiting shaft 16. It should be noted that a screen is equipped with four sets of limiting pins, which are not shown in the figure and will be configured later. The internal hexagonal limiting shaft 16 is provided with a first pin hole 17, and the connecting shaft 14 is provided with a second pin hole 18. If disassembly is not assisted by the limiting pins, at least two people are required to operate. By reserving the first pin hole 17 and the second pin hole 18, single-person operation can be achieved. During disassembly, the internal hexagonal limiting shaft 16, which is engaged in the first internal hexagonal slot 11, is squeezed to enter the second internal hexagonal slot 15. The limiting pin is inserted between the second pin hole 18 and the first pin hole 17 to limit the movement and prevent the internal hexagonal limiting shaft 16 from resetting. Then, the other set of hinge structure 5 can be disassembled for easier operation.
