[0002] Fasteners are a wide range of mechanical parts used for fastening connections. They are used in a broad range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, mold making, and hydraulics. Various types of fasteners can be found on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters, and supplies, making them the most widely used basic mechanical components. Fasteners are characterized by their numerous varieties and specifications, diverse performance and applications, and a high degree of standardization, serialization, and generalization.

[0003] Based on the existing technology, fasteners are galvanized using a hot-dip galvanizing treatment device to form a zinc-iron alloy coating on the surface. The temperature of the zinc liquid is generally between 450-470℃. After hot-dip galvanizing, the surface of the fastener will have residual heat, and the fastener needs to be cooled down before processing, which is inconvenient for handling. Therefore, a fastener hot-dip galvanizing treatment device is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution for a fastener hot-dip galvanizing treatment device, including a treatment device frame 1 and support legs 2 installed at the four corners of the bottom of the treatment device frame 1. Drainage pipes are symmetrically arranged on the treatment device frame 1, and the two drainage pipes are respectively connected to two chambers. The outer surface of the placement cylinder 7 is uniformly provided with leak holes of the same size. Electric slide rails 3 are symmetrically installed at the top of the processing device frame 1. Fixed frames 4 are slidably mounted on both electric slide rails 3. The electric slide rails 3 are commercially available models, representing mature existing technology. Their working principle will not be elaborated upon here. The electric slide rails 3 have limited travel, thus limiting the movement of the fixed frames 4. The driven gear 11 at one end of the placement cylinder 7 is located above the two driving gears 16. When the placement cylinder 7 moves downwards, it meshes with the driving gear 16. When the driving gear 16 rotates, it drives the driven gear 11 to rotate as well, causing the placement cylinder 7 to rotate and allowing the fasteners inside the placement cylinder 7 to undergo galvanizing. Lifting cylinders 6 are installed at the top of both fixed frames 4. The telescopic ends of the two lifting cylinders 6 extend into the interior of the fixed frames 4 and are fitted with connecting blocks 17. Connecting rods 18 are installed on both connecting blocks 17. A strip plate 19 is installed at one end of each connecting rod 18. A connecting column 10 is rotatably connected to each of the two strip plates 19 near the bottom. A placement cylinder 7 is installed at one end of each connecting column 10. A partition 5 is installed in the middle of the interior of the processing device frame 1. The partition 5 divides the interior of the processing device frame 1 into two chambers. The material of the partition 5 can be nanoporous calcium silicate board or ceramic fiber module, etc., for heat insulation to reduce the impact of heat on the clean water. One chamber contains clean water and the other chamber contains zinc liquid. The temperature of the clean water is 20-40 degrees Celsius. A sliding groove adapted to the connecting rod 18 is provided on one side of each of the two fixed frames 4. The lifting cylinder 6 drives the connecting block 17 to move up and down, and at the same time, it can drive the placement cylinder 7 to move up and down. The electric slide rail 3 runs synchronously, so that the two fixed frames 4 move together to adjust the position of the placement cylinder 7.

[0016] A cover plate 12 is provided on the placement cylinder 7. Connecting pieces 13 are symmetrically installed on the cover plate 12. Screws 14 are inserted through both connecting pieces 13. The placement cylinder 7 has a through-hole that matches the cover plate 12. Threaded holes that match the screws 14 are symmetrically arranged at the through-hole of the placement cylinder 7. One end of a connecting post 10 passes through a strip plate 19 and a driven gear 11 is installed thereon. Connecting rods 15 are symmetrically installed through the processing device frame 1. One end of each of the two connecting rods 15 is located in one of the two chambers of the processing device frame 1 and a driving gear 16 is installed thereon. A strip frame 8 is installed on the front of the processing device frame 1. A drive motor 9 is mounted on frame 8. The power output end of the drive motor 9 is fixedly connected to a connecting rod 15. A connecting pulley 20 is connected between the two connecting rods 15. The connecting pulley 20 is located inside the strip frame 8. When the drive motor 9 is powered on, it drives one connecting rod 15 to rotate. The connecting pulley 20 on one connecting rod 15 drives the other connecting rod 15 to rotate. The two connecting rods 15 rotate synchronously. The drive gear 16 on the connecting rods 15 rotates together. (The surfaces of the parts that need to come into contact with liquid in the above structure are coated with a special coating. They can come into contact with zinc liquid and clean water.)

[0017] The working principle of this utility model is as follows: (the position of the placement cylinder 7 is as follows) Figure 1 (As shown) Rotate screw 14, screw 14 exits the threaded hole on the placement cylinder 7, separating cover plate 12 from placement cylinder 7. Place the fasteners to be galvanized into placement cylinder 7, then close cover plate 12 on the outside of placement cylinder 7. Rotate screw 14, screw 14 connects with the threaded hole on placement cylinder 7, closing cover plate 12 and placement cylinder 7. Lifting cylinder 6 operates, driving connecting block 17 to move downwards. Connecting block 17 drives strip plate 19 to move downwards, immersing placement cylinder 7 into the chamber containing molten zinc. Driven gear 11 meshes with a driving gear 16, energizing drive motor 9, driving connecting rod 15 to rotate. Connecting belt on connecting rod 15... Wheel 20 drives another connecting rod 15 to rotate. The two connecting rods 15 rotate synchronously, and the drive gear 16 on the connecting rod 15 rotates together. When the drive gear 16 rotates, it drives the meshing driven gear 11 to rotate together, driving the placement cylinder 7 to rotate. The placement cylinder 7 can be selected in different chambers. After the fasteners inside the placement cylinder 7 are galvanized, the lifting cylinder 6 drives the placement cylinder 7 to move upward. Then the electric slide rail 3 runs, driving the two fixed frames 4 to move together, moving the placement cylinder 7 above the chamber containing clean water. The lifting cylinder 6 moves the placement cylinder 7 downward into the clean water to cool the galvanized fasteners.

[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
