Description

Technical Field

[0001] This utility model relates to the field of injection hooks, specifically to a net-penetrating injection hook that is easy to assemble and install. Background Technology

[0002] Injection-molded hooks are widely used connectors in home and industrial applications, playing a crucial role in fixing window and door screens. Traditional injection-molded hooks typically employ a single-clamp design, achieving fixation through a simple snap-fit ​​between the hook body and the screen mesh. Injection-molded hooks, as a new type of connector, aim to replace traditional screws, adhesives, or Velcro fasteners to meet the demands for rapid installation, strong weather resistance, and structural stability of window and door screens.

[0003] Existing injection hooks have the following drawbacks: The screen mesh needs to fit perfectly against the window frame edge, but traditional injection hooks lack a precise positioning structure, making them prone to misalignment due to human error during installation. This necessitates repeated adjustments, resulting in low efficiency. For example, installers must visually align the hook surface with the rough surface; even slight deviations can cause the screen mesh edge to curl or gaps to become too large, hindering quick assembly. Traditional designs rely solely on a single row of hook teeth for engagement, concentrating the force point. Strong pressure is required during installation to ensure proper engagement, and disassembly is difficult due to hook tooth deformation. This design is particularly inconvenient in screen mesh applications, as screen mesh requires frequent cleaning or replacement. The repeated pressing and forceful pulling of traditional injection hooks easily damages the hook teeth or rough surface. Traditional injection hooks lack physical limits, relying solely on hook tooth friction for fixation. When the screen mesh is subjected to lateral tension, the hook teeth can easily slip off the rough surface, leading to connection failure. For example, pushing or pulling the screen mesh may cause the hook teeth to separate from the rough surface due to lateral tension. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a mesh injection hook that is easy to assemble and install, which can effectively solve the technical problems of existing injection hooks being inconvenient to assemble quickly, as well as the injection hooks being prone to deformation and falling off.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a mesh-penetrating injection hook that is easy to assemble and install, including a first adhesive tape and a second adhesive tape. One end of the first adhesive tape extends outward to form several inverted rods, which are evenly distributed between adjacent inverted rods. The inverted rods extend outward to form two hook portions, which are symmetrically arranged between each other. One end of the first adhesive tape extends outward to form several positioning rods, which are evenly distributed between adjacent positioning rods. The positioning rods extend outward to form round heads. One end of the second adhesive tape is recessed inward to form several inverted grooves, which are evenly distributed between adjacent inverted grooves. The hook portions are engaged with the inverted grooves. One end of the second adhesive tape is recessed inward to form several positioning holes. The positioning rods pass through the positioning holes, and the round heads pass through the positioning holes and extend to the outside of the second adhesive tape.

[0006] Furthermore, an adhesive layer is provided at one end of the first adhesive tape, and a release film is provided at the bottom of the adhesive layer.

[0007] Furthermore, one end of the first adhesive strip extends outward to form several limiting rods, which are symmetrically arranged between adjacent limiting rods. The surface of each limiting rod protrudes outward to form two engaging blocks, which are symmetrically arranged between each other. One end of the second adhesive strip is recessed inward to form several limiting grooves, which are symmetrically arranged between adjacent limiting grooves. Each limiting groove has two engaging slots, which are symmetrically arranged between each other. The engaging blocks and the engaging slots are engaged and connected.

[0008] Furthermore, the first adhesive tape and the second adhesive tape have the same thickness.

[0009] Furthermore, both the first adhesive tape and the second adhesive tape are made of nylon.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The mesh injection hook of this utility model is easy to assemble and install. Through the interlocking connection between the barbed part and the inverted groove, the first adhesive tape and the second adhesive tape are quickly assembled, which significantly improves the installation efficiency. Each inverted rod is provided with two symmetrical barbed parts. The bidirectional interlocking structure can distribute the force and avoid the risk of single hook breaking or loosening. The inverted rod and the positioning rod are evenly distributed to ensure that the pressure on the contact surface of the adhesive tape is balanced and prevent deformation or detachment caused by local stress concentration.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The following is combined Figure 1 and Figure 2 The following is a detailed description of the easily assembled mesh-penetrating injection hook of this utility model: The easily assembled mesh-penetrating injection hook includes a first adhesive tape 1 and a second adhesive tape 2. One end of the first adhesive tape 1 extends outward to form several inverted rods 6, which are equidistantly arranged. Each inverted rod 6 extends outward to form two hook portions 7, which are symmetrically arranged. One end of the first adhesive tape 1 extends outward to form several positioning rods 9, which are equidistantly arranged. Each positioning rod 9 extends outward to form a round head 10. One end of the second adhesive tape 2 is recessed inward to form several inverted grooves 8, which are equidistantly arranged. The hook portions 7 engage with the inverted grooves 8. One end of the second adhesive tape 2 is recessed inward to form several positioning holes 3, through which the positioning rods 9 pass. The round head 10 passes through the positioning hole 3 and extends to the outside of the second adhesive tape 2. One end of the first adhesive tape 1 is provided with an adhesive layer 4, and the bottom of the adhesive layer 4 is provided with a release film 5. One end of the first adhesive tape 1 extends outward to form a plurality of limiting rods 11, which are symmetrically arranged between adjacent limiting rods 11. The surface of the limiting rod 11 protrudes outward to form two locking blocks 12, which are symmetrically arranged between the two locking blocks 12. One end of the second adhesive tape 2 is recessed inward to form a plurality of limiting grooves 13, which are symmetrically arranged between adjacent limiting grooves 13. The limiting groove 13 is provided with two locking grooves 14, which are symmetrically arranged between the two locking grooves 14. The locking blocks 12 and the locking grooves 14 are engaged and connected. The thickness of the first adhesive tape 1 and the second adhesive tape 2 is the same. Both the first adhesive tape 1 and the second adhesive tape 2 are made of nylon material.

[0017] In this embodiment, the positioning rod 9 passes through the positioning hole 3, and the round head 10 extends to the outside of the second adhesive tape 2, forming a physical limiting structure. This ensures that the positions correspond perfectly during the two bonding operations, avoiding manual installation deviations. Simultaneously, the positioning rod 9 passing through the positioning hole 3 achieves limiting and positioning functions, further stabilizing the connection between the first adhesive tape 1 and the second adhesive tape 2, preventing easy detachment. The release film 5 protects the adhesive layer 4 from contamination; it can be directly peeled off for application, simplifying the construction process and making it particularly suitable for rapid on-site installation. The adhesive layer 4 can be made of different adhesive materials, such as pressure-sensitive adhesives. The adhesive, with its initial bonding force controlled by the release film 5, satisfies both temporary fixation needs and permanent bonding. The interlocking connection between the limiting rod 11 and the limiting groove 13 effectively resists lateral sliding of the adhesive tape under shear force. The bidirectional interlocking between the interlocking block 12 and the interlocking groove 14 further disperses the horizontal force, preventing structural instability caused by unilateral force. The first adhesive tape 1 and the second adhesive tape 2 have the same thickness and are flush with the substrate surface after installation, avoiding unevenness caused by thickness differences and improving the overall aesthetics of the doors and windows. The mechanical interlocking structure supports multiple disassembly and assembly, and the first adhesive tape 1 and the second adhesive tape 2 can be recycled, reducing long-term maintenance costs.

[0018] The mesh-penetrating injection hook of this embodiment, which is easy to assemble, achieves rapid assembly of the first adhesive tape 1 and the second adhesive tape 2 through the interlocking connection between the barb part 7 and the inverted groove 8, which significantly improves the installation efficiency. Each inverted rod 6 is provided with two symmetrical barb parts 7. The bidirectional interlocking structure can distribute the force and avoid the risk of single hook breaking or loosening. The inverted rod 6 and the positioning rod 9 are equally distributed to ensure that the pressure on the contact surface of the adhesive tape is balanced and to prevent deformation or detachment caused by local stress concentration.

[0019] Installation steps and process: Clean the adhesive area of ​​the door and window frame to ensure it is free of oil or dust. Peel off the release film 5 at the bottom of the first adhesive tape 1 to expose the adhesive layer 4. Attach the first adhesive tape 1 horizontally to the preset position on the door and window frame and press for 10 seconds to ensure full contact of the adhesive layer 4. Align the screen mesh with the area of ​​the first adhesive tape 1 with the hanging rod 6 and press the screen mesh firmly to engage the hanging rod 6, positioning rod 9, and limiting rod 11 on the first adhesive tape 1 with the screen mesh. Align the area of ​​the second adhesive tape 2 with the hanging groove 8 and press the second adhesive tape 2 to engage the hanging groove 8 with the hook part, engage the positioning hole 3 with the round head 10, and engage the engaging groove 14 with the engaging block 12. The screen mesh can then be fixed to the door and window using the injection hook.
