Description

Technical Field

[0001] This utility model relates to the field of injection hooks, specifically an injection hook designed to prevent detachment. Background Technology

[0002] Injection hooks are connectors widely used in home and industrial applications, playing a particularly important role in securing doors, windows, and curtains. Traditional injection hooks typically employ a single snap-fit ​​design, achieving fixation through a simple interlocking action between the hook and the curtain.

[0003] However, existing injection hooks have the following drawbacks: First, uneven hook spacing or unreasonable arrangement leads to localized stress concentration, making them prone to detachment during long-term use or under external impact. Second, the single-clamp design lacks sufficient gripping force, especially when curtains are frequently opened and closed or bear heavy loads, causing the hooks to easily slip off the curtain fibers, resulting in poor stability. Furthermore, the lack of an effective hook structure makes the curtains prone to displacement or complete detachment when subjected to lateral tension. Additionally, traditional mushroom-shaped injection hooks have a roughly cylindrical hook body and a roughly circular head formed at the top of the cylindrical hook body. When these round-headed mushroom-shaped injection hooks are hooked with curtains, their smooth periphery does not provide a protruding angle for hooking with the curtains, resulting in a low effective hooking rate and insufficient bonding force, making it easy for the curtains to detach from the injection hook. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an injection hook that prevents detachment, which can effectively solve the technical problems of uneven force distribution, poor stability, and easy detachment of existing injection hooks.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an anti-drop injection hook, including a base belt, the surface of which is provided with a plurality of hooks, which are arranged at equal intervals between adjacent hooks. Each hook includes a fixing part and a rod part provided in the fixing part. One end of the rod part extends outward to form two locking parts, which are symmetrically arranged. Both ends of the fixing part extend outward to form connecting parts. A groove is formed between the connecting parts and the locking parts. The surface of the base belt is also provided with a pull rod perpendicular to the base belt, and one end of the pull rod extends outward to form an inverted part.

[0006] Furthermore, an adhesive layer is provided at the bottom of the baseband, and a release film is provided at the bottom of the adhesive layer.

[0007] Furthermore, the fixing part, the rod part, the snap-fit ​​part, and the connecting part are integrally formed.

[0008] Furthermore, the inverted portion and the snap-fit ​​portion are both on the same horizontal plane.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The injection hook of this utility model is designed to prevent detachment. The hooks are evenly spaced to ensure uniform force distribution and avoid the risk of detachment caused by local stress concentration. The cooperation between the double snap-fit ​​part and the connecting part forms a two-way locking mechanism, which significantly improves the gripping stability of the injection hook. The setting of the vertical pull rod and the inverted part enhances the shear resistance of the injection hook. The inverted part increases the contact area and forms multiple anti-detachment insurance, which can prevent the injection hook from easily detaching. Attached Figure Description

[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 Figures 1-3 A detailed description of an anti-detachment injection hook according to this utility model is provided:

[0017] An anti-detachment injection hook includes a base band 1. A plurality of hook bodies 2 are disposed on the surface of the base band 1, with adjacent hook bodies 2 arranged at equal intervals. Each hook body 2 includes a fixing part 3 and a rod part 4 disposed on the fixing part 3. One end of the rod part 4 extends outward to form two locking parts 5, which are symmetrically arranged. Both ends of the fixing part 3 extend outward to form connecting parts 6, and a groove 7 is formed between the connecting part 6 and the locking part 5. A pull rod 8 perpendicular to the base band 1 is also disposed on the surface of the base band 1. One end of the pull rod 8 extends outward to form an inverted part 9. An adhesive layer 10 is disposed at the bottom of the base band 1, and a release film 11 is disposed at the bottom of the adhesive layer 10. The fixing part 3, rod part 4, locking part 5, and connecting part 6 are integrally formed. The inverted part 9 and the locking part 5 are both on the same horizontal plane.

[0018] When in use, the injection hook can be installed on the door or window by tearing off the release film 11. Then, the side with the hook body 2 is aligned with the curtain, and the curtain can be hooked onto the injection hook by pressing the curtain, which can prevent the curtain from easily coming off.

[0019] In this embodiment, an injection hook designed to prevent detachment has hook bodies 2 arranged at equal intervals to ensure uniform force distribution and avoid the risk of detachment caused by localized stress concentration. The cooperation between the double snap-fit ​​part 5 and the connecting part 6 forms a two-way locking mechanism, which significantly improves the gripping stability of the injection hook. The vertical pull rod 8 and the inverted part 9 enhance the shear resistance of the injection hook, and the inverted part 9 increases the contact area, forming multiple anti-detachment safety measures to prevent the injection hook from easily detaching.

[0020] Installation steps and process: Clean the adhesive area of ​​the door and window frame to ensure there is no oil or dust. Peel off the release film 11 at the bottom of the base tape 1 to expose the adhesive layer 10. Attach the base tape 1 horizontally to the preset position on the door and window frame and press for 10 seconds to ensure the adhesive layer 10 is in full contact. Align the curtain with the hook 2 area and press the curtain firmly to embed the fibers into the slot 7, so that the snap part 5 and the hanging part 9 hook the curtain. Gently pull the curtain to check the fixing effect and ensure that the curtain is hooked.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
