Accordion folding insect screen

Abstract

This utility model discloses an accordion-style folding insect-proof net, including a first insect-proof structure and a second insect-proof structure. A rotating structure rotatably connects the first and second insect-proof structures, utilizing the triangular structure of the first and second protective angles to support them, effectively preventing overall deformation and displacement during extreme weather conditions such as strong winds. After the first and second insect-proof structures are closed, initial positioning is achieved through magnetic attraction between a magnetic block and a magnetic groove. A secondary fixation is achieved by inserting a combined protrusion into a combined slot. A third fixation is achieved by rotating and locking a limiting hook at the limiting protrusion, greatly improving overall stability. Simultaneously, the use of two sets of threaded ends provides lateral positioning for the first and second insect-proof structures, further increasing stability.

Description

Technical Field

[0001] This utility model relates to the field of insect-proof nets, specifically an accordion-fold insect-proof net. Background Technology

[0002] In agricultural greenhouse cultivation, the invasion of insects can cause serious damage to crops, affecting their yield and quality. Currently, traditional insect control methods mostly rely on fixed insect nets for physical barriers. However, these nets suffer from insufficient structural stability in their design. When encountering extreme weather conditions such as strong winds, fixed insect nets, lacking effective wind-resistant buffering mechanisms, cannot withstand the enormous pressure and tension generated by strong winds. They are prone to local deformation, tearing, or even complete collapse, leading to the failure of the insect barrier and its inability to provide sustained and stable insect control. This fails to meet the urgent need for efficient and reliable insect control technology in modern agricultural greenhouse cultivation.

[0003] Therefore, this utility model provides an accordion-style folding insect-proof net. Utility Model Content

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figure 1-4 This utility model discloses an accordion folding insect-proof net, including a first insect-proof structure 1 and a second insect-proof structure 3, with a rotating structure 2 rotatably connecting the first insect-proof structure 1 and the second insect-proof structure 3.

[0015] The first insect-proof structure 1 includes a first metal outer frame 11, a protective strip 12 is fixedly connected to the outer top of the first metal outer frame 11, the first metal outer frame 11 has a horizontally placed U-shaped structure, a combined protrusion 13 is fixedly connected to the center of the top of the first metal outer frame 11, and first protective corners 14 are fixedly connected to the inner walls on both sides of the top of the first metal outer frame 11. Four sets of magnetic grooves 16 are opened on the outer wall of the first metal outer frame 11, and the four sets of magnetic grooves 16 are respectively opened at the four corners of the outer wall of the first metal outer frame 11.

[0016] It should be noted that the first protective corner 14 inside the first insect-proof structure 1 can support the first metal outer frame 11, preventing the first metal outer frame 11 from deforming under strong winds. The triangular design of the two sets of first protective corners 14 can support the top two sides of the first metal outer frame 11. The protective strip 12 itself is relatively wide. After the first insect-proof structure 1 and the second insect-proof structure 3 are combined, it can prevent rainwater from seeping into the top connection gap between the first metal outer frame 11 and the second insect-proof structure 3 and causing corrosion. The magnetic groove 16 can work with the second insect-proof structure 3 to be adsorbed and fixed.

[0017] The side frame of the first metal outer frame 11 is rotatably connected to a limit hook 17. There are four sets of limit hooks 17, which are symmetrically installed on both sides of the first metal outer frame 11.

[0018] After the first insect-proof structure 1 and the second insect-proof structure 3 are combined, the four sets of limiting hooks 17 can be locked at the corresponding structures of the second insect-proof structure 3, playing a supporting and fixing role.

[0019] The bottom of the first metal frame 11 is fixedly connected to the first insect-proof net 15, and the bottom of the first insect-proof net 15 is fixedly connected to the first plastic plate 18. The first plastic plate 18 has the same structure as the first metal frame 11. The first insect-proof net 15 is made of soft fabric and can be bent as needed. The first shaping plate 18 is fixedly installed at the window on the top of the agricultural greenhouse. After the first insect-proof structure 1 and the second insect-proof structure 3 are closed inward, the first insect-proof net 15 can effectively prevent mosquitoes from flying into the greenhouse.

[0020] The rotating structure 2 includes a rotating shaft body 21. The rotating shaft body 21 has threaded grooves symmetrically opened at both ends, and each set of threaded grooves is threaded with a set of threaded ends 22.

[0021] The threaded end 22 can limit the two ends of the first insect-proof structure 1 and the second insect-proof structure 3, so as to prevent misalignment of the two ends of the first insect-proof structure 1 and the second insect-proof structure 3 after installation.

[0022] The second insect-proof structure 3 includes a second metal outer frame 31, which has the same structure as the first metal outer frame 11. The second metal outer frame 31 also has a horizontally shaped U-shaped structure. A combination slot 32 is provided at the top of the second metal outer frame 31 corresponding to the combination protrusion 13. The inner walls on both sides of the top of the second metal outer frame 31 are fixedly connected with second protective corners 33, which correspond to the first protective corners 14 and have the same structure. Four sets of magnetic blocks 35 are fixedly connected to the outer wall of the second metal outer frame 31, which correspond to four sets of magnetic slots 16. Limiting protrusions 36 are fixedly connected to the side frames of the second metal outer frame 31. There are four sets of limiting protrusions 36, which are symmetrically fixed to the two side frames of the second metal outer frame 31. A second insect-proof net 34 is fixedly connected to the bottom of the second metal outer frame 31. A second shaping plate 37 is fixedly connected to the bottom of the second insect-proof net 34. The second shaping plate 37 has the same structure as the second metal outer frame 31.

[0023] When the first insect-proof structure 1 and the second insect-proof structure 3 are rotated and closed, the magnetic block 35 is attracted into the corresponding magnetic groove 16, which plays a preliminary fixing role. At the same time, the combined protrusion 13 is inserted into the combined slot 32, which can fix the sides and top of the first insect-proof structure 1 and the second insect-proof structure 3. At this time, the protective strip 12 can cover the top of the second metal frame 31, thereby preventing mosquitoes from entering the interior through the gap between the second metal frame 31 and the top of the first metal frame 11. At the same time, the four sets of limiting hooks 17 can be rotated so that the limiting hooks 17 are locked in the corresponding limiting protrusions 36, which plays a further fixing role.

[0024] The first metal outer frame 11, the first shaping plate 18, the second metal outer frame 31, and the second shaping plate 37 are all rotatably connected to the rotating shaft body 21.

[0025] In actual use, the first metal outer frame 11 and the second metal outer frame 31 can be rotated upwards to complete the closure and fixation of the first insect-proof structure 1 and the second insect-proof structure 3. The first plastic plate 18 and the second plastic plate 37 are both installed at the windows on the top of the agricultural greenhouse. The first insect-proof net 15 and the second insect-proof net 34 can play a role in blocking mosquitoes.

[0026] Working principle: The triangular structure of the first protective angle 14 and the second protective angle 33 is used to support the first insect-proof structure 1 and the second insect-proof structure 3, preventing the overall device from deforming or shifting during extreme weather such as strong winds, thus improving the overall structural strength and service life. At the same time, after the first insect-proof structure 1 and the second insect-proof structure 3 are closed, the four sets of magnetic blocks 35 are magnetically fixed in the magnetic groove 16 for initial positioning and fixation. The combined protrusion 13 is inserted into the combined slot 32 for secondary fixation. Then, the four sets of limiting hooks 17 are rotated and clamped at the limiting protrusion 36 to achieve a third layer of fixation, which greatly improves the overall stability. At the same time, the use of the two sets of threaded ends 22 can also provide lateral positioning for the first insect-proof structure 1 and the second insect-proof structure 3, further increasing stability.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
