Description

Technical Field

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

[0002] Retractable screens, also known as invisible screens, are a type of screen that uses a roller and torsion spring mechanism to automatically retract the screen. A typical structure of an invisible screen includes a hollow housing such as a screen box, which contains the roller, torsion spring mechanism, and locking mechanism. Its working principle is that when the screen is pulled out, the torsion spring deforms and stores energy. When the screen is released and the locking is disengaged, the torsion spring releases energy, driving the roller to rotate and retract the screen into the screen box. The locking mechanism ensures the screen remains stably in place at any position, preventing it from retracting immediately upon release.

[0003] An invention patent application with application number CN202010120346.0 discloses an invisible screen window assembly, including an invisible screen window body, an invisible screen window buckle device, and an invisible screen window roller connecting device. The invisible screen window body includes a window frame, a screen mesh, a roller box, and a pull frame. The invisible screen window roller connecting device is disposed inside the roller box. The two ends of the window frame are respectively fixed to the wall by connectors. The roller box is disposed at the front end of the window frame, and the roller box is fixedly connected to the window frame. The interior of the window frame is provided with...

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0029] like Figure 1 and Figure 2 As shown, a screen window structure that is easy to assemble and disassemble includes a frame, a screen roll box 1, and a screen fabric 2. The screen roll box 1 is equipped with a roller, a torsion spring roller mechanism, and a locking mechanism. The frame includes an upper horizontal bar 4, a lower horizontal bar 5, a vertical bar 3, two first corner brackets 7, and two second corner brackets 8. The screen roll box 1 is connected to the frame and is located on the opposite side of the vertical bar 3. The screen roll box 1 has a through hole structure for the screen fabric 2 to pass through. A fixing member 6 is connected to each of the upper and lower ends of the screen roll box 1. The two fixing members 6 are respectively connected to one end of the upper horizontal bar 4 and the lower horizontal bar 5 through a first corner bracket 7. The other ends of the upper horizontal bar 4 and the lower horizontal bar 5 are respectively connected to the upper and lower ends of the vertical bar 3 through a second corner bracket 8. This modular connection between the frame components and between the frame components and the two fixing members 6 via corresponding corner brackets facilitates quick assembly and disassembly of the components, greatly simplifying daily cleaning, replacement, and maintenance.

[0030] like Figures 1-4 As shown, push rods 9 are slidably connected to the upper crossbar 4 and the lower crossbar 5. Windproof strips 10 of a certain width are heat-fused and fixedly connected to the four corners of the screen fabric 2, and a threading strip 11 is heat-fused and fixedly connected to one end of each windproof strip 10. Threading holes 13 are provided on both the roller and the push rod 9. The threading strip 11 on the left side is detachably connected to the threading hole 13 of the roller in the screen box 1, and the threading strip 11 on the right side is detachably connected to the threading hole 13 of the push rod. A clearance through hole 14 is provided on the push rod 9 for the screen fabric 2 to pass through, and the clearance through hole 14 connects to the threading hole 13. The lower end of the upper crossbar 4 and the upper end of the lower crossbar 5 are both provided with guide grooves 16. The upper end and the lower end of the push rod 9 are each connected to a sliding member 17. The sliding member 17 is provided with a sliding strip 12 that is adapted to the guide groove 16.

[0033] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the fastener 6 is provided with a first locking rail 606, and the first corner bracket 7 is provided with a second locking rail 706. When the fastener 6 and the second locking rail 706 are engaged, the first locking rail 606 and the second locking rail 706 are aligned, and there is a gap between them for the windproof sheet 10 to pass through. The end of the windproof sheet 10 is connected to a limiting slider 15, which can slide along the aligned first locking rail 606 and second locking rail 706. The limiting slider 15 can slide left and right and limit the windproof sheet 10. During the sliding process, it can generate a vertical tension force on the windproof sheet 10, preventing the screen fabric 2 from shifting or wrinkling during unfolding or folding, further improving the stability of the structure and the smoothness of use.

[0034] like Figure 1 and Figure 7 As shown, the second angle code 8 has a second insertion part 801, which is horizontally arranged. A second spring piece 802 is provided on the second insertion part 801, and a second buckle 803 is provided on the second spring piece 802. The upper crossbar 4 and the lower crossbar 5 are provided with a second slot and a second locking hole at the end connected to the second angle code 8. When the second insertion part 801 is inserted into the second slot and fully inserted, the second buckle 803 on the second spring piece 802 is locked into the second locking hole, realizing the quick connection and positioning of the second angle code 8 with the upper crossbar 4 or the lower crossbar 5.

[0035] like Figure 1 and Figure 7 As shown, the second angle code 8 also has a third insertion part 804, which is vertically arranged. The third insertion part 804 is provided with a third spring piece 805 and a third buckle 806. The upper and lower ends of the vertical rod 3 are provided with a third slot and a third locking hole. When the third insertion part 804 is inserted into the third slot and fully inserted, the third buckle 806 on the third spring piece 805 locks into the third locking hole, realizing the quick connection and positioning of the second angle code 8 and the vertical rod 3.

[0036] In summary, this utility model effectively solves the problem of inconvenient assembly and disassembly of existing invisible screen windows through the modular snap-fit ​​design of the first corner bracket 7, the second corner bracket 8, the upper horizontal bar 4, the lower horizontal bar 5, the vertical bar 3, and the fixing component 6, realizing the rapid assembly and disassembly of each component. At the same time, the windproof plates 10 connected at the four corners of the screen fabric 2, in conjunction with the connecting strips 11, prevent the screen fabric 2 from being damaged due to lack of protection during use, significantly improving the practicality and durability of the screen window.
