[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] The embodiment of the present application provides a rear screen structure that can be quickly disassembled and assembled, which can solve the problem that in the related art, rear screens are used for casement windows, and the rear screens are fixed to the window frames with screws, which makes them inconvenient to disassemble and assemble.

[0025] See also Figure 1-Figure 3 A rear screen structure that can be quickly disassembled and assembled includes: a window frame 1, in which a casement window 2 and a screen 3 are hingedly connected in sequence; the screen 3 includes a frame 31, two hangers 32, a connecting piece 33 and a screen 34, the frame 31 is hingedly arranged on the window frame 1, the two hangers 32 are relatively arranged on the frame 31, the connecting piece 33 is spliced ​​and arranged on the two hangers 32, and the screen 34 is arranged on the connecting piece 33.

[0026] The window frame 1, as the basic supporting structure, is first installed in a suitable position.

[0027] The casement window 2 is connected to the window frame 1 in a hinged manner to achieve the functions of opening and closing.

[0028] The frame 31 of the screen window 3 is also hingedly arranged on the window frame 1, and is usually located outside or inside the casement window 2, depending on the design requirements.

[0029] Assembly of screen window:

[0030] Two hangers 32 are arranged opposite to each other on the frame 31 , and the two hangers are used to support and fix the gauze 34 .

[0031] The connecting member 33 is designed with a structure adapted to the hanging member 32 and is spliced ​​together with the hanging member 32 through a sliding groove, a clamping groove or a similar mechanism.

[0032] The gauze 34 is fixed inside the connecting member 33 and its shape and position are usually maintained by structures such as the edge guard 332.

[0033] In actual operation, when the screen window needs to be disassembled for cleaning or replacement of the screen 34, the user only needs to simply separate the connecting member 33 from the hanging member 32 to easily remove the entire screen window portion. Conversely, during installation, the user only needs to align the connecting member 33 with the hanging member 32 and splice them together to complete the installation of the screen window.

[0034] The screen window can be quickly disassembled and assembled through a simple splicing method without the need for complex tools or cumbersome steps, greatly improving the convenience of use and maintenance.

[0035] The quick disassembly and assembly feature of the screen window allows the user to easily clean or replace the screen 34, reducing the difficulty and cost of maintenance.

[0036] Since there is no need to drill holes in the window frame or use fasteners such as screws, the window surface remains neat and beautiful, avoiding the problem of affecting the overall visual effect due to improper fixing methods.

[0037] The risk of damage to fixings or deformation of connecting parts due to frequent disassembly and assembly is reduced, and the service life of the screen window is extended.

[0038] The structure is designed so that the screen can be flexibly installed or removed as needed, suitable for use in different seasons or environmental conditions. For example, in summer, the screen can be installed to prevent mosquitoes from entering the room, and in winter, the screen can be removed for better ventilation or cleaning of the window.

[0039] Specifically, the hanging member 32 in this embodiment includes a fixing plate 321 and a clamping strip 322 . The fixing plate 321 is arranged on the frame 31 by bolts, and the clamping strip 322 is arranged on the fixing plate 321 . The clamping strip 322 is L-shaped.

[0040] The fixing plate 321 is the main part of the hanging member 32, and the fixing plate 321 is firmly mounted on the screen window frame 31 by bolts. Such a design ensures that the hanging member 32 can stably support the screen 34 and the connecting member to prevent loosening or falling off during use.

[0041] The clip strip 322 is L-shaped and is arranged on the fixing plate 321. The L-shaped clip strip design has two main functions: first, it provides an interface adapted to the connector 33 so that the connector can be easily spliced ​​on the hanging part; second, it increases the stability of the connection through its shape characteristics to prevent the connector from easily detaching from the hanging part when subjected to external force.

[0042] First, the fixing plate 321 is fixed to a predetermined position of the screen frame 31 by bolts. Then, the connecting member 33 is aligned with the clamping strip 322 on the fixing plate 321, and is slid or clamped along the L-shaped track of the clamping strip until the connecting member is firmly connected to the hanging member 32. This design makes the disassembly and assembly process of the screen window simple and quick, and can be completed without the use of additional tools.

[0043] Specifically, the connecting piece 33 in this embodiment includes two matching pieces 331 and a protective edge 332, and the two matching pieces 331 are relatively arranged on both sides of the protective edge 332; the matching piece 331 is provided with a sliding groove adapted to the clamping strip 322, and the matching piece 331 is spliced ​​and arranged on the corresponding fixed plate 321.

[0044] The matching piece 331 is designed with a slide groove that matches the clamping strip 322 in the hanging piece 32. This slide groove allows the matching piece 331 to slide along the L-shaped track of the clamping strip 322, thereby achieving a stable connection with the hanging piece.

[0045] The edge guard 332 is usually made of metal or other solid materials to surround and protect the gauze 34. It serves as a bridge connecting two fittings 331 and also provides support and fixation for the gauze 34.

[0046] When installing the screen window, first fix the hanging member 32 to the screen window frame 31 through the fixing plate 321 and the bolts. Then, align the two matching members 331 of the connecting member 33 with the clamping strip 322 on the hanging member 32, and slide along the L-shaped track of the clamping strip. As the matching members 331 slide, they gradually move closer and finally join together, while fixing the edge guard 332 and the screen 34 in the middle. In this way, the screen window is firmly connected to the window frame.

[0047] It should be noted that the edge guard 332 is formed by enclosing and splicing four aluminum alloy strips, and the gauze 34 is arranged inside the edge guard 332 .

[0048] The two sealing strips 5 are respectively clamped and arranged at the top and bottom between the fixing plate 321 and the matching piece 331. This position selection ensures that the sealing strip can effectively close the gap between the screen window and the window frame to prevent air, dust or insects from entering the room through these gaps.

[0049] The sealing strip 5 is connected to the fixing plate 321 and the fitting 331 by a clamping method. This connection method is simple and firm, and can be installed and removed without additional tools. At the same time, the clamping method also allows the sealing strip to be replaced when necessary to maintain its sealing performance.

[0050] Specifically, a plurality of plug rods are disposed at the bottom of the sealing strip 5 , and mounting holes 6 adapted to the plug rods are provided at the upper and lower ends of the fixing plate 321 and the matching piece 331 .

[0051] The bottom of the sealing strip 5 is designed with a plurality of insertion rods, which may be flexible or have a certain elasticity so as to be conveniently inserted and fixed in the mounting hole 6. The number and distribution of the insertion rods are determined according to the length of the sealing strip and the required fixing strength.

[0052] The main body of the plug rod and the sealing strip 5 is usually made of materials with good elasticity and weather resistance, such as rubber, silicone or some plastic materials. These materials can ensure that the plug rod can maintain a stable connection after being inserted into the mounting hole, while being able to adapt to certain deformation and displacement.
