Abstract
Description
Technical Field
[0001] This utility model relates to the field of decorative painting frame structure, and in particular to an aluminum profile for a picture frame with a hidden hook function. Background Technology
[0002] Existing picture frame products typically use traditional aluminum alloy profiles, which are suspended by metal hangers on the back. These hangers are usually externally mounted and are typically fixed to the slots on the back of the picture frame profile with screws. Traditional aluminum alloy profiles typically have hooks installed on the outside of the profile, with the hook portion protruding from the back of the frame. This not only exposes the hook during hanging, affecting the overall aesthetics of the frame, but also creates a gap between the frame and the wall due to the hook's thickness, preventing the frame from fitting snugly against the wall and resulting in a subpar installation. In recent years, a large number of adhesive wall hooks have also appeared on the market. These hooks are directly attached to the wall with adhesive. Unlike nails or screws, adhesive hooks usually have a certain thickness and protrude further from the wall, causing the entire frame to be further away from the wall. This is not only less aesthetically pleasing, but also increases instability due to frame tilting, seriously affecting both aesthetics and stability. Utility Model Content
[0003] Purpose of this utility model: The purpose of this utility model is to provide a solution to the problem that traditional aluminum alloy profile hooks protrude significantly from the back of the picture frame after installation, causing the hooks to be exposed when hanging, affecting the overall aesthetics of the picture frame; Another purpose of this utility model is to provide a solution to the problem that when using existing adhesive wall hooks, since the wall hook itself already protrudes from the wall, if the picture frame hook is not designed to be recessed, more overlapping protrusions will occur, further increasing the gap between the picture frame and the wall, resulting in a worse overall decorative effect and stability.
[0004] Technical solution: A picture frame aluminum profile with a hidden hook function, including a profile body, a hook slot is provided at the bottom of the profile body, and a bolt fixing part is provided at the top inside the hook slot.
[0005] Furthermore, the hook slot is recessed 1mm-9mm into the interior of the profile body.
[0006] Beneficial effects: When the hook is installed in the slot by the bolt fixing part, the fixing base part of this utility model can be completely stored inside the profile. Only the load-bearing part used for hanging on the wall can be extended as needed. Moreover, the extended part can be cleverly concealed by the profile structure after the picture frame is hung. No hook trace can be seen from any external angle. This completely eliminates the damage of the hook to the overall visual aesthetics of the picture frame. Whether it matches a minimalist or exquisite style of decoration, it can maintain the integrity and coordination of the picture frame's appearance and greatly improve the overall aesthetics of the picture frame. This utility model, through its recessed slot design, eliminates the need for hooks to add extra thickness to the picture frame, allowing the back of the picture frame to fit snugly against the wall. Even if there is a tiny gap, it is within a controlled range, effectively improving the defect of uneven and suspended picture frames in traditional structures. This makes the picture frame look more refined and stable, reduces dust accumulation, and lowers the risk of the picture frame shifting due to external forces, thus improving its practicality and convenience. This utility model is not only compatible with traditional wall hangings that require drilling for installation, such as nails and screws, but also perfectly compatible with adhesive wall hooks that have become widely used in recent years due to their convenient installation and lack of damage to the wall surface. Because the hook slot itself has a recessed space, even if the adhesive wall hook itself has a certain protruding height, this recessed space can accommodate the protruding parts of the picture frame hook and the wall hanging, avoiding the problem of both protruding and increasing the distance between the picture frame and the wall. No matter what kind of wall hanging the user chooses, it can ensure that the picture frame maintains a good wall-mounting effect and a hidden appearance, providing users with more diversified installation options to meet the needs of different scenarios. This utility model has a simple and clear structural design, which will not significantly increase the difficulty and cost of profile production. Existing profile production equipment and processes can basically meet production needs, making it easy to achieve large-scale industrial production. At the same time, during the assembly process, the installation can be completed simply by fixing the hook into the slot with screws. The operation steps are simple and easy to understand, requiring no professional technicians. Whether it is batch assembly in the factory or self-installation by users, it can be easily completed, which is conducive to the rapid promotion and application of the product and has good market prospects and practical value.

[0008] In the diagram: 1. Profile body; 2. Hook slot; 3. Bolt fixing part. Detailed Implementation
[0009] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example
[0010] like Figure 1 and Figure 2 As shown, a picture frame aluminum profile with a hidden hook function is provided, including a profile body 1, characterized in that: a hook groove 2 is provided at the bottom of the profile body 1, and a bolt fixing part 3 is provided at the top inside the hook groove 2; the hook groove 2 is recessed into the interior of the profile body 1 by 1mm-9mm; In use, firstly, using the screw fixing part 3 located inside the hook slot 2 at the bottom of the profile body 1, the hidden hook, which is a metal part, is securely installed in the hook slot 2 with screws. Since the hook slot 2 is a recessed groove located at the lower end of the back of the profile and extending inward, its design of retracting into the profile body 1 allows the fixing base of the hidden hook to be completely contained within the profile outline, while allowing the load-bearing part of the hook to extend out of the frame for hanging on the wall mount. When it is necessary to hang the picture frame on the wall, simply hang the load-bearing part of the hook extending from the frame on the wall mount. Even if the wall hanger is adhesive and protrudes from the wall, the protruding wall hanger can be completely covered by the hidden hook inside the frame profile. No hook structure can be seen from the outside. The hidden design also allows the back of the frame to be flush against the wall or maintain a very small controlled gap. This effectively avoids the problem of large unevenness between the back of the frame and the wall caused by the thickness of the hook. Thus, not only does the simple structural design achieve reliable hook fixation, which is convenient for mass production and assembly, but it also greatly improves the aesthetics of the frame and ensures the flatness of the frame when hanging, bringing a better user experience.
[0011] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
