[0002] The galvanization of screws usually adopts hot-dip galvanization or electro-galvanization process. Hot-dip galvanization is to immerse the screws in molten zinc so that a zinc layer covers their surfaces, while electro-galvanization is to place the screws in an electrolyte containing zinc ions and use an electric current to deposit zinc ions on the screw surfaces to form a zinc layer.

[0003] In the existing screw surface galvanizing device, when performing electro-galvanization, the two ends of the drum are usually lapped by using guide rails to keep it horizontal, so that rolling electro-galvanization can be carried out inside the electroplating device, and the guide rails are mostly installed on the device by drilling holes in the device and then using tools such as screwdrivers to roll and install the guide rails on the device through screws.

[0004] In the above technology, the guide rails are fixedly installed on the upper part of the overall device by using tools such as screwdrivers, resulting in the need to repeatedly rotate for screw disassembly and installation during replacement, increasing the complexity of the operation, and easily causing damage to the threaded holes and resulting in the situation where the guide rails cannot be installed. Therefore, a screw surface galvanizing device is proposed to solve the above problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: A zinc plating device for the surface of screws includes a main body 1. A plurality of square grooves 6 are opened inside the upper end of the main body 1. The inside of the plurality of square grooves 6 can store electroplating solutions and acid solutions, etc. to pickle, electroplate, and wash the screws inside the drum, etc., and the right end is open for discharging operations. The left part of the top of the main body 1 is threadedly connected with a positioning assembly. The lower parts of both ends of the positioning assembly are slidably connected with a sliding rod 5. The sliding rod 5 can position and fix the guide rail 4. The lower part of the sliding rod 5 is in contact with the top of the main body 1. The main body 1 can support and keep the sliding rod 5 horizontally fixed. The upper left part of the sliding rod 5 is slidably connected inside the card slot 7. The card slot 7 can clamp to make the sliding rod 5 not slide and remain fixed. The lower parts of both ends of the sliding rod 5 are slidably connected with a positioning block 8. The outside of the positioning block 8 is slidably connected inside the upper end of the main body 1. The positioning block 8 can make the sliding rod 5 be quickly positioned and fixed. The side end of the sliding rod 5 is fixedly connected with a fixed block 9. The fixed block 9 can position the guide rail 4, which is convenient for installation and does not require determining the position.

[0032] Referring to Figures 2 - 3, a guide rail 4 is slidably connected to the outside of the fixed block 9. The guide rail 4 is M-shaped and can overlap both ends of the roller so that the roller can rotate horizontally. The lower part of the guide rail 4 is slidably connected to the outside of the sliding rod 5. The sliding rod 5 can keep the guide rail 4 sliding vertically only. A clamping block 11 is elastically connected to the inside of the guide rail 4 through a first spring 13. The outside of the clamping block 11 is slidably connected to the inside of the side end of the sliding rod 5. A square groove is provided at the side end of the sliding rod 5 so that the clamping block 11 can slide in to keep the guide rail 4 fixed. One end of the first spring 13 is fixedly connected to the outside of the side end of the clamping block 11, and the other end of the first spring 13 is fixedly connected to the inside of the lower end of the guide rail 4. The extrusion of the first spring 13 can keep the guide rail 4 fixed relative to the sliding rod 5. A slider 12 is fixedly connected to the side end of the clamping block 11. The outside of the slider 12 is slidably connected to the inside of the upper end of the main body 1. The slider 12 can prevent the clamping block 11 from completely sliding out of the inside of the lower end of the guide rail 4. A tapered block 15 is slidably connected to the inside of the upper end of the clamping block 11. An arc groove is provided at the upper end of the clamping block 11. The side end inclined surface of the tapered block 15 can be extruded to make the clamping block 11 slide out of the inside of the side end of the sliding rod 5, which is convenient for disassembling and replacing the guide rail 4. The outside of the tapered block 15 is slidably connected to the inside of the lower end of the guide rail 4. A rotating shaft 10 is fixedly connected to the lower part of the tapered block 15. The rotating shaft 10 can drive the tapered blocks 15 at both ends to rotate to release the limit. The outside of the rotating shaft 10 is slidably connected to the middle inside of the lower end of the guide rail 4. The guide rail 4 restricts the rotating shaft 10 to rotate only relative to itself, and the position is fixed. An I-shaped block 14 is slidably connected to the right part of the rotating shaft 10. The left end of the I-shaped block 14 is square and can drive the rotating shaft 10 to rotate, and the right end is a square magnet that can keep the rotating shaft 10 relatively fixed and not rotate to affect the stability of the guide rail 4. The outside of the I-shaped block 14 is slidably connected to the right part of the lower end of the guide rail 4. The adsorption between the guide rail 4 and the magnet can keep the I-shaped block 14 relatively fixed.

[0033] Referring to Figure 2 and Figure 4 , the positioning component includes a bolt 3. The lower part of the bolt 3 is threadedly connected to the upper part of the left end of the main body 1. The bolt 3 can fix the positioning rod 2 to the upper end of the main body 1. The lower end of the bolt 3 is threadedly connected to the outside of the positioning rod 2. The positioning rod 2 can clamp and keep the sliding rods 5 at both ends from sliding up and remain fixed. The lower part of the positioning rod 2 is in contact with the upper part of the left end of the main body 1, and it is convenient for positioning and installing the sliding rod 5. Card slots 7 are provided at the lower parts of both ends of the positioning rod 2. In this way, the situation of replacing the size of the guide rail 4 to avoid the position of the threaded hole due to damage to the threaded hole will not occur, which increases the practicability of the overall device.

[0034] Working principle: By sliding down, the positioning block 8 can slide into the interior of the main body 1. Subsequently, the left end of the card slot 7 and the sliding rod 5 can be clamped. Then, the positioning rod 2 can be fixed to the main body 1 through the bolt 3. Then, slide out the I-shaped block 14 so that it can rotate. Subsequently, rotate it to drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the conical block 15 to rotate half a circle. The conical block 15 squeezes the upper circular groove of the clamping block 11, causing the clamping block 11 to drive the two end sliders 12 to slide into the interior of the lower end of the guide rail 4 and squeeze the first spring 13. Then, slide the fixing block 9 into the interior of the lower end of the guide rail 4 to complete the positioning of the guide rail 4. Rotate the I-shaped block 14 back to its original position, and the I-shaped block 14 drives the rotating shaft 10 and the conical block 15 to slide back to their original positions. At this time, the clamping block 11 slides into the interior of the side end of the sliding rod 5 under the extrusion of the first spring 13 and remains fixed. Then, the I-shaped block 14 can be slid back to its original position to keep the rotating shaft 10 fixed and no longer slide. When disassembly is required, the I-shaped block 14 can be slid out, and its rotation can drive the rotating shaft 10 and the conical block 15 to rotate, causing the clamping block 11 and the slider 12 to slide back into the interior of the guide rail 4. Then, it can be slid upward to replace the guide rail 4. After replacement, the screw can be driven by the roller into the square groove 6 for water washing, pickling, and electroplating, and then blanking is carried out at the right end of the main body 1.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
