Description

Technical Field

[0001] This utility model relates to the field of agricultural protection facilities, and in particular to an insect-proof net. Background Technology

[0002] Insect-proof netting is an agricultural facility that uses physical barriers to control pests. It is typically a mesh structure woven from materials such as polyethylene or synthetic fibers. It is widely used in ventilation openings, door curtains, and skylights of agricultural greenhouses. By creating a physical barrier, it effectively prevents the invasion of pests such as mosquitoes and moths, thereby reducing the spread of crop diseases and pesticide use, and ensuring the yield and quality of agricultural products.

[0003] However, existing insect-proof nets have certain structural shortcomings. Currently, common insect-proof nets are mostly made by directly sewing together a square horizontal mesh and two square vertical meshes. This manufacturing process results in a raised area at the corner where the horizontal and vertical meshes meet, where four layers of mesh material are superimposed and sewn together. This area is not only significantly thick, affecting the flatness and sealing of the net surface, but also, when used in areas such as agricultural greenhouse skylights, usually requires multiple sets of such nets to be spliced ​​together. The cumulative thickness of multiple raised areas is even more pronounced, which may hinder the smooth opening and closing of skylights and provide potential gaps for pests to enter, reducing the overall protective effect of the insect-proof net.

[0004] Therefore, it is necessary to provide a new insect-proof net to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an insect-proof net.

[0006] The insect-proof net provided by this utility model includes: an insect-proof net body, the insect-proof net body comprising multiple sets of net layers, each set of net layers comprising one horizontal net and two vertical nets, the two vertical nets being welded to both ends of the horizontal net respectively; the horizontal nets of adjacent net layers are connected sequentially, and the vertical nets of adjacent net layers are connected sequentially; the length of the multiple sets of horizontal nets is the same, and the length of the multiple sets of vertical nets increases layer by layer from the middle of the insect-proof net body to both sides; the welding methods of the horizontal net and the vertical nets include horizontal welding, vertical welding, and oblique welding.

[0007] Preferably, in the horizontal welding method, the horizontal mesh is square, and the end of the vertical mesh away from the horizontal mesh has a 45° bevel. The two ends of one horizontal side of the horizontal mesh near the vertical mesh are welded to the side of the vertical mesh near the horizontal mesh.

[0008] Preferably, in the longitudinal welding method, the horizontal mesh is square, and the end of the longitudinal mesh away from the horizontal mesh has a 45° bevel. In the longitudinal welding method, the length of the horizontal mesh is less than the length of the horizontal mesh in the horizontal welding method, and the length of the longitudinal mesh is greater than the length of the longitudinal mesh in the horizontal welding method. In the longitudinal welding method, the two longitudinal sides of the horizontal mesh are respectively welded to the side of the longitudinal mesh closest to the horizontal mesh.

[0009] Preferably, the top and bottom of the insect-proof net body are fixedly connected to mounting brackets, and the mounting brackets have mounting grooves on the side away from the insect-proof net body, with rubber strips installed in the mounting grooves.

[0010] Preferably, the mounting bracket has two bidirectional threaded rods rotatably connected internally, and each bidirectional threaded rod has a compression rod slidably connected to both ends of the mounting bracket via a spline. The compression rod is threadedly connected to the bidirectional threaded rod and is used to fix the rubber strip.

[0011] Preferably, a knob is fixedly connected to the middle of the bidirectional threaded rod, and one side of the knob extends out of the mounting bracket.

[0012] Compared with related technologies, the insect-proof net provided by this utility model has the following beneficial effects: 1. Structural integration and improved flatness This invention replaces traditional sewing with welding, allowing each mesh layer (including one horizontal mesh and two vertical meshes) to form a complete, integrated structure after welding. Each welded mesh layer is a single layer, fundamentally avoiding the localized protrusions that inevitably occur in traditional processes due to the stitching and overlapping of multiple mesh materials. This results in a smoother surface for the entire insect-proof net, significantly improving its sealing performance and aesthetics.

[0013] 2. Significantly enhanced connection strength and durability Because the contact area and bonding strength of the welded joints are much greater than those of thread stitching, the connection between the horizontal and vertical meshes is much stronger. This integrated connection method can effectively withstand the impact of external forces such as strong winds and rain, greatly reducing the risk of tearing or damage to the mesh layers at the joints, thereby significantly improving the overall structural stability and service life of the insect net.

[0014] 3. Wide adaptability to shape and flexible application. This utility model provides two types of structured mesh: horizontally welded and vertically welded, each with different mechanical properties. The horizontally welded type offers lateral stability and is suitable for flat installation; the vertically welded type has longitudinal ductility and is easy to bend longitudinally. Users can choose the most suitable insect-proof mesh type according to the specific greenhouse structure, skylight shape, and protection requirements, achieving precise adaptation and wide application of the product.

[0015] 4. The installation is secure and the seal is reliable. By combining the mounting bracket with the rubber strip, this invention achieves a tight fixation to the window frame. The rubber strip, as a flexible medium, undergoes elastic deformation between the mounting bracket and the window frame, effectively filling the gap and utilizing friction to achieve a firm fixation. Simultaneously, it achieves an excellent sealing effect, eliminating entry channels for pests through the installation gaps. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Example 1 Please see Figures 1 to 4 An insect-proof net includes: an insect-proof net body 1, the insect-proof net body 1 including multiple sets of net layers 2, each set of net layers 2 including one horizontal net 3 and two vertical nets 4, the two vertical nets 4 being welded to both ends of the horizontal net 3 respectively; the horizontal nets 3 of adjacent net layers 2 are connected in sequence, and the vertical nets 4 of adjacent net layers 2 are connected in sequence; the length of the multiple sets of horizontal nets 3 is the same, and the length of the multiple sets of vertical nets 4 increases layer by layer from the middle of the insect-proof net body 1 to both sides; the welding method of the horizontal net 3 and the vertical net 4 includes horizontal welding, vertical welding and oblique welding.

[0021] In the horizontal welding method, the horizontal mesh 3 is square, and the end of the vertical mesh 4 away from the horizontal mesh 3 is provided with a 45° oblique angle. The two ends of one horizontal side of the horizontal mesh 3 near the vertical mesh 4 are respectively welded to the side of the vertical mesh 4 near the horizontal mesh 3.

[0022] When the insect-proof net body 1 is welded horizontally, the two ends of the horizontal mesh 3 near the horizontal edge of the vertical mesh 4 are welded to the two vertical meshes 4 respectively. This connection method provides continuous and robust support in the horizontal direction, resulting in a stable structure suitable for covering flat surfaces or large curvature radii where high horizontal strength and overall flatness are required.

[0023] Example 2 Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 In the longitudinal welding method, the horizontal mesh 3 is square, and the end of the longitudinal mesh 4 away from the horizontal mesh 3 is provided with a 45° oblique angle. In the longitudinal welding method, the length of the horizontal mesh 3 is less than the length of the horizontal mesh 3 in the horizontal welding method, and the length of the longitudinal mesh 4 in the longitudinal welding method is greater than the length of the longitudinal mesh 4 in the horizontal welding method. In the longitudinal welding method, the two longitudinal sides of the horizontal mesh 3 are respectively welded to the side of the longitudinal mesh 4 closest to the horizontal mesh 3.

[0024] When the insect-proof net body 1 is longitudinally welded, the dimensions of the horizontal mesh 3 and the vertical mesh 4 in each mesh layer 2 are different from those in the transverse welding method. In this method, the horizontal mesh 3 is shorter, while the vertical mesh 4 is longer. The two longitudinal edges of the horizontal mesh 3 are welded to the two vertical meshes 4 respectively. This structure gives the net body better extensibility and flexibility in the longitudinal direction, making it easier to adapt to installation environments with certain longitudinal bending requirements.

[0025] Horizontal and vertical welding methods replace the traditional right-angle butt joints. This beveled connection effectively avoids the stacking and accumulation of four layers of mesh at the corners, fundamentally eliminating significant protrusions. When multiple sets of such mesh layers 2 (with the same length of horizontal mesh 3 and the length of vertical mesh 4 increasing from the middle to both sides) are connected in sequence, the joints transition smoothly, naturally forming a smooth arched surface without sharp creases that fits closely with structures such as agricultural greenhouse skylights.

[0026] Please see Figure 2 and Figure 6The top and bottom of the insect-proof net body 1 are fixedly connected to mounting brackets 5. A mounting groove is formed on the side of the mounting bracket 5 away from the insect-proof net body 1, and a rubber strip 6 is placed inside the mounting groove. Two bidirectional threaded rods 7 are laterally rotatably connected inside the mounting bracket 5. A compression rod 8 is slidably connected to both ends of each bidirectional threaded rod 7 via a spline. The compression rod 8 is threadedly connected to the bidirectional threaded rod 7 and is used to fix the rubber strip 6. A knob 9 is fixedly connected to the middle of each bidirectional threaded rod 7, and one side of the knob 9 extends out of the mounting bracket 5.

[0027] It should be noted that, under the constraint of the spline, the extrusion rod 8 will not rotate with the rotation of the bidirectional threaded rod 7.

[0028] The working principle of the insect-proof net provided by this utility model is as follows: Installation, fixing, and rubber strip replacement principle The insect-proof net body 1 is fixed to the greenhouse window frame by mounting brackets 5 at its top and bottom. One of the core functions of the mounting brackets 5 is to provide a clamping mechanism that facilitates the replacement of the rubber strips 6, thereby achieving a tight fixation to the window frame and convenience for long-term maintenance.

[0029] Its specific operation and replacement principle are as follows: Fixing principle: A rubber strip 6 of a specific size is placed into the mounting groove of the mounting bracket 5. Then, the mounting bracket 5 containing the rubber strip 6 is snapped into or aligned with the corresponding position on the greenhouse window frame. At this time, the rubber strip 6, acting as a flexible filling medium, undergoes elastic deformation between the mounting bracket 5 and the window frame, effectively filling the gap between them. Utilizing the friction and deformation pressure of the rubber material, a firm fixation is achieved between the mounting bracket 5 and the window frame, while also providing a good sealing effect.

[0030] Replacement principle: When the rubber strip 6 ages or wears down due to long-term use, resulting in a decrease in fixing effect or sealing performance, it can be quickly replaced through the following steps: Rotate knob 9 to drive the bidirectional threaded rod 7 to rotate inside the mounting bracket 5. The rotation of the bidirectional threaded rod 7 drives the two compression rods 8, which are threaded at both ends, to slide towards each other inside the mounting bracket 5, thereby releasing the clamping force on the rubber strip 6. At this point, the old rubber strip 6 can be easily removed from the mounting slot. After placing the new rubber strip 6 into the mounting slot, rotate knob 9 in the opposite direction to move the two compression rods 8 in opposite directions, thus firmly clamping and fixing the new rubber strip 6 in the mounting slot from both sides, completing the replacement operation.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
