A plating reinforced hanger

Abstract

This application relates to an electroplated reinforced hanger, comprising a main shaft and multiple annular bases vertically distributed along the main shaft. Multiple hook assemblies are arranged around the annular bases. Each hook assembly includes a support rod, an arc-shaped elastic element, and an S-shaped elastic element. The arc-shaped and S-shaped elastic elements are connected to the support rod, with the arc-shaped elastic element positioned above the S-shaped elastic element. The arc-shaped elastic element is configured to abut against the inner wall of the cylindrical material through inward radial elastic deformation, while the S-shaped elastic element is configured to bend upward and abut against the outer wall of the cylindrical material through outward radial elastic deformation. By incorporating the arc-shaped and S-shaped elastic elements, the arc-shaped elastic element abuts against the inner wall of the material with its toughness, while the S-shaped elastic element undergoes outward radial elastic deformation. Through bidirectional elastic clamping, the cylindrical material can be firmly fixed and will not fail due to slight differences in its diameter, effectively preventing the risk of detachment under severe liquid flow impact.

Description

Technical Field

[0001] This application relates to the field of electroplating technology, and in particular to an electroplating reinforced hanging bracket. Background Technology

[0002] Electroplating is one of the core technologies in the field of surface treatment. By depositing a coating on the surface of metal workpieces, the corrosion resistance, wear resistance and appearance of the workpieces can be significantly improved. In the electroplating industry, electroplating racks are key tools used to suspend and fix workpieces and immerse them in the treatment solution.

[0003] For electroplating of cylindrical materials such as hydraulic cylinder barrels, automotive shock absorber sleeves, and precision hardware bushings, common fixing methods often involve rigid clamping or simple hooks. While rigid clamping is secure, it can easily cause scratches on the inner wall of the material during precision machining and is not suitable for the slight differences in materials of different diameters, resulting in poor versatility. Simple hooks, on the other hand, pose a risk of insecure fixing, and the material can easily fall off when entering or leaving the liquid tank or when impacted by liquid flow. Therefore, there is an urgent need for a reinforced electroplating rack that can solve the above problems. Utility Model Content

[0004] This application provides a more stable electroplated reinforced hanging bracket.

[0005] The electroplated reinforced hanging bracket provided in this application adopts the following technical solution: An electroplated reinforced hanging bracket includes a main shaft and a plurality of annular bases distributed vertically along the main shaft. A plurality of hook assemblies are arranged around the annular bases. Each hook assembly includes a support rod, an arc-shaped elastic element, and an S-shaped elastic element. The arc-shaped elastic element and the S-shaped elastic element are connected to the support rod. The arc-shaped elastic element is located above the S-shaped elastic element. The arc-shaped elastic element is configured to abut against the inner wall of a cylindrical material through inward radial elastic deformation. The S-shaped elastic element is configured to bend upward and abut against the outer wall of the cylindrical material through outward radial elastic deformation.

[0006] Preferably, the support rod includes a main rod and an inclined rod. The inclined rod is connected to the annular base and tilts outward from the annular base, extending to the outer side of the upper annular base. The main rod is connected to the inclined rod and is connected to the arc-shaped elastic element and the S-shaped elastic element.

[0007] Preferably, the main rod has an upper guide hole, which is located between the arc-shaped elastic element and the S-shaped elastic element.

[0008] Preferably, the inclined rod has a lower guide hole.

[0009] Preferably, the hook assemblies on the adjacent two layers of the annular base are staggered.

[0010] Preferably, a hook is provided at the top of the main shaft for connecting to the gantry frame.

[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, by setting up arc-shaped and S-shaped elastic elements, when hanging cylindrical materials, the arc-shaped elastic element generates inward radial elastic deformation, using its toughness to abut against the inner wall of the material, forming the main fixing point. When the S-shaped elastic element is subjected to downward pressure, it undergoes outward radial elastic deformation, thereby lifting and abutting against the outer wall of the material from below, forming an auxiliary fixing point. Through bidirectional elastic clamping from the inside and outside, the cylindrical material can be firmly fixed and will not fail due to slight differences in its diameter, effectively preventing the risk of falling off under the impact of violent liquid flow.

[0012] 2. By setting guide holes on the main rod, the flowability of the treatment liquid inside the cylindrical material is improved, ensuring that the inside of the cylindrical material can be fully covered by the treatment liquid, thereby improving the electroplating efficiency.

[0013] 3. By setting the lower guide hole on the inclined rod, the fluid resistance of the entire rack during the lifting process is reduced, which promotes the overall renewal and exchange of the treatment liquid around the rack and further improves the electroplating efficiency.

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] This application provides an electroplated reinforced hanging bracket, such as Figure 1 and Figure 2 As shown, it includes a vertical spindle 1 and multiple annular bases 2 distributed vertically on the spindle 1. Both the spindle 1 and the annular bases 2 are made of metal materials with sufficient rigidity and corrosion resistance, such as low carbon steel or stainless steel. The top of the spindle 1 is provided with a hook 4, which is used to connect to the gantry of the electroplating processing line. The gantry can drive the hanger into the processing liquid so that a coating is formed on the surface of the cylindrical material on the hanger.

[0019] like Figure 1 As shown, the annular base 2 is provided with multiple hook components 3. The hook components 3 on adjacent annular bases 2 are staggered to avoid mutual interference between the hook components 3, ensuring unobstructed flow of the processing liquid, avoiding the shielding effect of the upper material on the lower material, and ensuring the consistency of the processing effect of all workpieces on the same hanger.

[0020] like Figure 1 and Figure 2 As shown, the hook assembly 3 includes a support rod 31, an arc-shaped elastic element 32, and an S-shaped elastic element 33. The support rod 31 is made of low-carbon steel, while the arc-shaped elastic element 32 and the S-shaped elastic element 33 are made of stainless steel. The support rod 31 includes a main rod 311 and a diagonal rod 312. The diagonal rod 312 is connected to the annular base 2 and tilts outward from the annular base 2, extending to the outer side of the upper annular base 2. The main rod 311 is connected to the diagonal rod 312 and is parallel to the main shaft 1. Thus, by setting the diagonal rod 312 and the vertical main rod 311, ample operating space is provided for the operator, and a sufficient space is formed between the main rod 311 and the upper annular base 2 for placing cylindrical materials without easily touching the annular base 2.

[0021] like Figure 2 As shown, the arc-shaped elastic element 32 and the S-shaped elastic element 33 are connected to the main rod 311. The arc-shaped elastic element 32 is located above the S-shaped elastic element 33. The arc-shaped elastic element 32 includes two arc-shaped elastic bodies symmetrically distributed on the main rod 311 and is configured to abut against the inner wall of the cylindrical material by inward radial elastic deformation. The S-shaped elastic element 33 includes two S-shaped elastic bodies symmetrically distributed on the main rod 311 and is configured to bend upward and abut against the outer wall of the cylindrical material by outward radial elastic deformation.

[0022] When suspending cylindrical materials, the operator places the material opening downwards onto the hook assembly 3. The inner wall of the material first contacts the arc-shaped elastic element 32, applying inward pressure. The arc-shaped elastic element 32 undergoes inward radial elastic deformation, using its toughness to abut against the inner wall of the material, forming the primary fixing point. Subsequently, the lower edge of the material presses against the S-shaped elastic element 33. Under downward pressure, the unique S-shaped structure of the S-shaped elastic element 33 undergoes outward radial elastic deformation, thereby lifting and abutting against the outer wall of the material from below, forming an auxiliary fixing point. Through bidirectional elastic clamping from both inside and outside, the cylindrical material can be firmly fixed without failure due to slight differences in its diameter, effectively preventing the risk of falling off under the impact of violent liquid flow.

[0023] like Figure 2As shown, the main rod 311 has an upper guide hole 311a, which is located between the arc-shaped elastic element 32 and the S-shaped elastic element 33. The treatment liquid can flow smoothly into and out of the cylindrical material through the upper guide hole 311a. The upper guide hole 311a is used to improve the flowability of the treatment liquid inside the cylindrical material, ensuring that the inside of the cylindrical material can be fully covered by the treatment liquid, thereby improving the electroplating efficiency.

[0024] like Figure 2 As shown, a lower guide hole 312a is provided on the inclined rod 312. The lower guide hole 312a effectively reduces the fluid resistance of the entire hanger during the lifting process, promotes the overall renewal and exchange of the treatment liquid around the hanger, and further improves the electroplating efficiency.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
