Description

Technical Field

[0001] This utility model relates to the field of hook tools for pipe powder coating operations, specifically to hooks for pipe powder coating. Background Technology

[0002] Aluminum alloy tubes are widely used in various applications due to their lightweight, high strength, and corrosion resistance, including support tubes for sports equipment such as horizontal bars and parallel bars, support frames for camping tarps, trekking poles / walking sticks, and medical IV stands. To enhance their weather resistance, wear resistance, and aesthetics, powder coating is essential. During the powder coating process, hooks are used to suspend the aluminum alloy tubes to ensure even coating.

[0003] However, existing hooks lack adaptability, making it difficult to securely attach aluminum alloy pipes of different diameters and shapes. Frequent replacements are necessary; either the pipe wobbles and falls when used with larger diameter pipes, or the hook is too tight when used with smaller diameter pipes, potentially damaging the inner wall and hindering operation, thus affecting powder coating quality and efficiency. Therefore, developing a powder coating hook that can adapt to various aluminum alloy pipe diameters while ensuring both suspension stability and smooth installation / removal has become a critical issue that urgently needs to be addressed in the aluminum alloy pipe powder coating industry. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hook for pipe powder coating, so as to overcome the above-mentioned shortcomings.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hook for pipe powder coating, including a hanging part and a pipe bearing part for insertion into the pipe;

[0006] The pipe bearing part includes a first support arm and a second support arm that are distributed in a cross-sloping manner, and a U-shaped loop connection part that connects the bottom of the first support arm and the bottom of the second support arm. The first support arm and the second support arm are used to abut against the inner wall of the pipe under the elastic deformation of the U-shaped loop connection part.

[0007] The pipe bearing section is located below the suspension section and is connected to the suspension section via the first support arm.

[0008] Preferably, the first support arm, the U-shaped loop connection, and the second support arm of the pipe bearing section are integrally formed by bending a metal wire.

[0009] Preferably, the first support arm and the second support arm are respectively provided with abutment protrusions for abutting against the inner wall of the pipe.

[0010] Preferably, the abutment protrusion is V-shaped, with the openings of the V-shaped abutment protrusions on both sides being distributed opposite to each other.

[0011] Preferably, the top ends of the first support arm and the second support arm extend upward to form the abutting protrusion.

[0012] Preferably, the top of the abutment protrusion of the first support arm extends upward to form an extension for connecting the bottom end of the suspension part.

[0013] Preferably, the extension is inclined and the inclined direction is V-shaped with an opening towards the second support arm between the inclined direction of the first support arm and the inclined direction of the first support arm.

[0014] Preferably, the metal wire cross-section of the pipe bearing part is circular and has a diameter of 2-3 mm.

[0015] Preferably, the distance between the apexes of the two abutting protrusions is 33-38 mm, and the vertical distance between the apex of the abutting protrusion and the bottom end of the U-shaped loop connection is 62-66 mm.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the hook uses the first support arm and the second support arm to be inserted into the pipe and abuts against the inner wall of the pipe under the elastic deformation of the U-shaped loop connection, so that the pipe is suspended on the hook; with the help of the U-shaped loop design, a good elastic deformation effect is achieved, which improves the adaptability and stability of the hook to pipes with different inner diameters and also ensures good installation and removal, avoiding the complicated operation of traditional manufacturers frequently changing different hooks to adapt to different pipe diameters for powder coating.

[0019] 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 illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Reference Figure 1 It can be seen that in the process of powder coating aluminum alloy pipes, the hooks are used to suspend the aluminum alloy pipes to achieve uniform coating.

[0021] like Figure 1 The hook includes a hook-shaped suspension part 1 for hooking the hook onto a suspension plate (a flat tool for suspending several aluminum alloy tubes, the plate having several hanging holes for the hook to hook onto).

[0022] The hook also includes a pipe support for insertion into the pipe, thereby suspending the pipe (such as an aluminum alloy pipe) below the suspension plate for subsequent pipe powder coating operations. At the same time, the insertion and connection between the pipe support and the pipe facilitates the installation or removal of the pipe.

[0023] The aforementioned pipe support portion is located below the suspension portion 1, and the hook-shaped suspension portion and the pipe support portion are formed by bending a cylindrical metal wire together.

[0024] The pipe support includes a first support arm 2 and a second support arm 3 that are arranged in a cross-sloping manner, and a U-shaped loop connection part 4 connecting the bottom of the first support arm 2 and the bottom of the second support arm 3. The top ends of the first support arm 2 and the second support arm 3 extend upward to form a V-shaped abutment protrusion 4. The openings of the two V-shaped abutment protrusions 4 are distributed opposite each other. The V-shape of the abutment protrusion is conventionally formed by the intersection of the first leg and the second leg. The distance between the vertices of the two abutment protrusions 4 (i.e., the intersection of the first leg 51 and the second leg 52 shown in the figure) is 35mm (the distance parameter can also be any value from 33mm to 38mm). The vertical distance between the vertices of the abutment protrusion 4 and the bottom end of the U-shaped loop connection part 3 is 64mm (or any value from 62mm to 66mm).

[0025] The first support arm 2 and the second support arm 3 are inserted into the pipe and abut against the inner wall of the pipe under the elastic deformation of the U-shaped loop connection part 4, so that the pipe is suspended on the hook. At the same time, with the help of the U-shaped loop design, the spacing between the apexes of the two abutment protrusions 5 and the vertical distance between the apex of the abutment protrusion 5 and the bottom of the U-shaped loop connection part 4 are designed to achieve a good elastic deformation effect and the insertion depth into the pipe. This improves the adaptability and stability of the hook to pipes with different inner diameters, and also ensures a smooth installation and removal effect. It avoids the complicated operation of manufacturers frequently changing different hooks to adapt to different pipe diameters for powder coating (after the hook is hooked on the suspension plate, it usually needs to be tightened with pliers to fix it to the suspension plate, so changing the hook is time-consuming and laborious).

[0026] Furthermore, the V-shaped abutment protrusion 5 is designed to make point contact with the inner wall of the pipe, reducing the risk of defects on the inner wall of the pipe. Simultaneously, the first leg 51 of the V-shaped abutment protrusion (i.e., Figure 1 The upper part of the support leg, which is far from the first support arm 2 and the second support arm 3, serves as a part for the operator to grip (the operator grips the first support leg 51 on both sides, which is abutting the protrusions, so that the first support arm and the second support arm on both sides can be elastically deformed, and the hook can be easily inserted into the pipe. That is, the V-shaped design is more convenient for the operator to grip the support arms on both sides to deform the operation compared to the dot-shaped protrusions).

[0027] The top of the abutment protrusion of the first support arm 2 extends upward to form an extension 6, such as Figure 1 The extension 6 is inclined and its inclination direction forms a V-shape with the opening facing the second support arm 3, with the top of the extension 6 connected to the bottom of the suspension part 1. This inclined extension 6 design prevents the suspension part 1 from hitting the inner wall of the pipe outlet, reducing the likelihood of defects and improving the quality of pipe processing.

[0028] Furthermore, after powder coating, paint accumulates on the hook's surface. Removing this paint typically involves burning it and then shaking it off. However, traditional hooks are prone to significant elastic deformation and weakening after burning, resulting in a short lifespan. This embodiment addresses this problem by changing the hook's thickness and incorporating a U-shaped loop design. The hook diameter is changed from the traditional 1.5mm to 2.5mm (in other embodiments, it can be any value between 2mm and 3mm), ensuring hook performance and extending its lifespan.
