Description

Technical Field

[0001] This utility model relates to the field of hook technology, and in particular to a hook connection structure. Background Technology

[0002] Existing hooks still have some shortcomings in design and use. Taking common adhesive hooks as an example, the connection structure between the main body and the back plate is often quite complex. When installing the hook body, the sliding buckle on the back plate can easily be obscured, leading to inconvenience during installation, misinstallation, and ultimately, the hook cannot be securely installed, affecting its load-bearing capacity and lifespan. Furthermore, the height of the main body relative to the back plate of existing adhesive hooks is usually fixed and cannot be adjusted according to actual needs, which limits its application scenarios and scope. For example, different stress points affect the hook's load-bearing capacity and durability. Also, when hanging items of different lengths, fixed-height hooks may not meet the requirements, resulting in wasted space or inconvenience.

[0003] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hook connection structure that is easy to install and has an adjustable height.

[0005] This utility model is achieved through the following technical solution:

[0006] To solve the above technical problems, this utility model provides a hook connection structure, including a back plate and a main plate, wherein a hook body is provided on the side of the main plate opposite to the attached base surface;

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This utility model's hook connection structure innovatively combines a sliding connection structure with a multi-position limiting structure, achieving adjustable suspension height. Through the cooperation of different types of locking positions and elastic locking elements (such as helical teeth, cantilever, or arch-bridge elastic arms), it not only greatly simplifies the suspension operation and achieves a convenient and quick "blind hanging" function, but also provides multiple height options, offering strong adaptability. More importantly, this utility model has high safety and reliability; even under external impact, it can quickly return to the locked state through the continuously cooperating limiting structure, effectively preventing items from falling and providing users with a safe, convenient, and flexible suspension experience.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] Please refer to Figures 1 to 2 This embodiment discloses a specific implementation of a hook connection structure. The hook connection structure mainly consists of a back plate 1 and a main plate 2. A hook 3 is provided on the outer side of the main plate 2 away from the substrate (e.g., a wall) for hanging items.

[0028] Preferably, the back panel 1 is connected to the substrate by pressure-sensitive adhesive, that is, by bonding.

[0029] The back plate 1 and the main plate 2 are not fixedly connected, but rather slide relative to each other via a sliding connection structure. This allows the main plate 2 to move up and down relative to the back plate 1 to accommodate different suspension height requirements. Simultaneously, to fix the main plate 2 at the selected height, this embodiment also includes a limiting structure to restrict downward movement of the main plate 2. This limiting mechanism does not restrict upward movement of the main plate 2.

[0030] The core of this limiting structure lies in the cooperation between the locking position 4 and the locking member 5. In this embodiment, the locking position 4 consists of equally spaced limiting teeth 41, while the locking member 5 is an elastic arm. The limiting teeth 41 are disposed on the back plate 1 or the main body plate 2, and the elastic arm is disposed at the corresponding position of the other component, ensuring that the two can interact with each other. The elastic arm is provided with mating teeth 51, which can mesh with the limiting teeth 41, thereby fixing the main body plate 2 in different positions.

[0031] To ensure that the main body plate 2 can slide smoothly relative to the back plate 1, this embodiment employs a combination design of vertical sliding groove 6 and vertical sliding rail 7. The vertical sliding groove 6 and vertical sliding rail 7 are respectively disposed on the back plate 1 and the main body plate 2, and extend in the vertical direction. The vertical sliding rail 7 slides within the vertical sliding groove 6, guiding the movement trajectory of the main body plate 2 and ensuring that it always moves in the vertical direction.

[0032] Of particular note is that, to facilitate operation and improve locking reliability, this embodiment designs the limiting tooth 41 and the mating tooth 51 as a helical tooth structure. For example, the tip of the limiting tooth 41 faces downwards, and the tip of the mating tooth 51 faces upwards. This design ensures that the main body plate 2 can only be pushed into the back plate 1 from bottom to top. Utilizing the effect of the inclined surface, the elastic arm can easily overcome resistance and engage with the limiting tooth 41. Simultaneously, this one-way locking characteristic also ensures the safety of the suspension and prevents accidental slippage.

[0033] The hook connection structure provided in this embodiment has the following advantages:

[0034] Easy to hang: The simple sliding structure and multi-position limit structure design allow users to quickly and easily install the hook without complicated alignment and fixing steps.

[0035] Blind hanging is possible: Even in low light or limited visibility conditions, users can sense the position of the limiting teeth by touch and achieve blind hanging operation.

[0036] Height adjustable: The setting of multiple limiting teeth allows the main body plate 2 to be fixed at different height positions to meet different suspension requirements.

[0037] High safety; the mating tooth 51 can sequentially engage with each limiting tooth 41. Even if the mating tooth 51 disengages from the current limiting tooth 41 due to force, it will sequentially enter the next limiting tooth 41 and engage with it, forming continuous locking protection, which greatly improves safety.

[0038] Example 2

[0039] Please refer to Figures 3 to 4 The main difference between this embodiment and Embodiment 1 lies in the specific form of the limiting structure. In this embodiment, the locking position 4 is a limiting groove 42 with equal spacing, while the locking member 5 adopts a cantilever elastic arm.

[0040] One end of the cantilevered elastic arm is fixed, while the other end is free. The middle of the elastic arm arches outward to form an arc-shaped structure, and a limiting protrusion 52 is provided at the arched part. The limiting protrusion 52 can be engaged into the corresponding limiting groove 42, thereby fixing the main body plate 2 in a specific position.

[0041] The hook connection structure in this embodiment also enables quick suspension and is simple and easy to operate; the equally spaced limiting groove design ensures multi-level height adjustment and strong adaptability. In addition, the limiting protrusion 52 and the limiting groove 42 can form a reliable engagement, and the equally spaced design of the limiting groove 42 ensures that even if the limiting protrusion 52 is dislodged by external force, it can quickly re-engage with the adjacent limiting groove to form continuous safety protection.

[0042] Unlike Embodiment 1, in this embodiment, the main body plate 2 can be pushed into the back plate 1 from bottom to top or from top to bottom. Of course, when pushing it in from top to bottom, a little force needs to be applied to overcome the resistance of the elastic arm.

[0043] To further enhance the user experience, this embodiment also includes a downwardly extending cover 21 at the lower end of the main body panel 2. The main function of the cover 21 is to protect the user's fingers from being scratched or abraded by the edge of the back panel 1 during operation.

[0044] Example 3

[0045] Please refer to Figures 5 to 6 This embodiment improves upon Embodiment 2 by modifying the structure of the locking member 5. In this embodiment, the locking member 5 adopts an arch-bridge type elastic arm.

[0046] Unlike cantilever-type elastic arms, the arch-bridge type elastic arm has fixed ends at both the top and bottom, forming an arch shape. The middle of the elastic arm also arches outward, forming a limiting protrusion 52. The limiting protrusion 52 can be engaged in the corresponding limiting groove 42 to fix the main body plate 2.

[0047] The arch-bridge elastic arm design makes hook installation more convenient, saving users time and effort. Multiple limiting slots provide users with various height options to meet individual needs. Furthermore, the stable support provided by the arch-bridge elastic arm ensures a tighter and more reliable fit between the limiting protrusion 52 and the limiting slot 42. Even under external impact, the limiting protrusion 52 can quickly return to its original position and re-engage with the adjacent limiting slot, forming a continuous safety protection mechanism.

[0048] Similar to Embodiment 2, in this embodiment, the main body plate 2 can be pushed into the back plate 1 from bottom to top or from top to bottom. When pushing it in from top to bottom, a little force is required.

[0049] The above embodiments demonstrate different implementations of the hook connection structure, all of which have the advantages of convenient hanging, blind hanging, and adjustable height.
