[0001] This utility model relates to the field of hot-dip galvanizing processing technology, and in particular to a hanger for hot-dip galvanizing processing. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is a highly efficient and widely used metal corrosion protection technology. This technology primarily involves applying a zinc layer to the surface of steel parts through a specific process to achieve corrosion protection. During hot-dip galvanizing, metal parts need to be suspended using hangers.

[0003] For example, application number CN221254674U discloses "a hanging fixture for hot-dip galvanizing" and specifically discloses that: an arc-shaped hook is rotatably mounted on the bottom of the fixed frame, the arc-shaped hook is formed by opening a notch on one side of a whole circular ring, a baffle is provided on the inner side of the notch, a rotating shaft is provided at one end of the baffle near the fixed frame, the baffle is rotatably mounted on the fixed frame through the rotating shaft, and a return coil spring is provided on the rotating shaft to drive the baffle to fit against the inner wall of the arc-shaped hook. However, when suspending metal, the hook will be damaged due to the weight of the metal products after long-term use. In the above technology, it is inconvenient to replace the hook during use, making the hook easy to break during use, thus causing the metal to fall, thereby reducing the practicality of the hanging fixture. Therefore, this utility model proposes a hanging fixture for hot-dip galvanizing to solve the above problems. Utility Model Content

The mounting block has an installation groove inside, the mounting groove has a connecting block inside, the connecting block has a fixing hole inside, and the fixing hole has a fixing block inside.

[0007] A further improvement is that the cross-section of the fixing hole is larger than the cross-section of the fixing block, and the fixing hole and the fixing block form an engaging structure.

[0008] A further improvement is made in that: the transmission structure includes a rotating wheel, a first bevel gear, a second bevel gear, a threaded rod, a threaded sleeve, and a limiting structure. The rotating wheel is installed on one side of the mounting block, the first bevel gear is installed inside the mounting block, one end of the rotating wheel is connected to one end of the first bevel gear, one end of the first bevel gear meshes with the second bevel gear, one end of the second bevel gear is equipped with a threaded rod, the outer wall of the threaded rod is provided with a threaded sleeve, and the bottom end of the threaded sleeve is connected to the top end of the fixed block.

[0009] A further improvement is that the limiting structure includes a limiting rod and a limiting sleeve. The limiting rod is installed inside the mounting block, and a limiting sleeve is provided on the outer wall of the limiting rod. One end of the limiting sleeve is connected to one end of the fixing block.

[0010] A further improvement is made in that: the adjustment mechanism includes a fixed rail, a movable block, a positioning hole, a mounting cavity, a positioning pin, and a telescopic spring.

Detailed Implementation

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a hanger for hot-dip galvanizing, including a mounting rod 1, an mounting block 2 installed on the lower outer side of the mounting rod 1, a replacement mechanism provided inside the mounting block 2, a hook 3 installed at the bottom end of the mounting block 2, and an adjustment mechanism provided on the inner side of the mounting rod 1.

[0020] The replacement mechanism includes a connecting block 10, a fixing hole 11, a fixing block 12, and a transmission structure. The mounting block 2 has an internal mounting groove, and the connecting block 10 is disposed inside the mounting groove. The connecting block 10 has an internal fixing hole 11, and the fixing hole 11 has an internal fixing block 12. The cross-section of the fixing hole 11 is larger than the cross-section of the fixing block 12. The fixing hole 11 and the fixing block 12 form a locking structure. The transmission structure includes a rotating wheel 13, a first bevel gear 14, and a second bevel gear. 15. Threaded rod 16, threaded sleeve 17, and limiting structure. The rotating wheel 13 is installed on one side of the mounting block 2. The first bevel gear 14 is installed inside the mounting block 2. One end of the rotating wheel 13 is connected to one end of the first bevel gear 14. One end of the first bevel gear 14 meshes with a second bevel gear 15. A threaded rod 16 is installed on one end of the second bevel gear 15. A threaded sleeve 17 is provided on the outer wall of the threaded rod 16. The bottom end of the threaded sleeve 17 is connected to the top end of the fixing block 12. When long-term... When the hook 3 needs to be replaced, the operator rotates the rotating wheel 13 to drive the first bevel gear 14 to rotate. Since the first bevel gear 14 and the second bevel gear 15 mesh with each other, the second bevel gear 15 drives the threaded rod 16 to rotate, which in turn drives the threaded sleeve 17 to move. Under the limit of the limit rod 18 and the limit sleeve 19, the threaded sleeve 17 drives the fixing block 12 to move, moving the fixing block 12 out of the fixing hole 11. At this time, the connecting block 10 can be taken out from the mounting block 2, the hook 3 can be removed, and then the new hook 3 can be taken out. The connecting block 10 is placed into the mounting block 2. Then, the rotating wheel 13 is rotated in the opposite direction to move the fixing block 12 into the fixing hole 11, fixing the position of the hook 3 and completing the installation of the hook 3. The hook 3 can be easily disassembled and installed, making it easier and faster to replace. Therefore, the hook 3 is not easy to break during use, and the metal is more stable during hot-dip galvanizing, thus greatly improving the practicality of the hanger.

[0021] The limiting structure includes a limiting rod 18 and a limiting sleeve 19. The limiting rod 18 is installed inside the mounting block 2. The limiting sleeve 19 is provided on the outer wall of the limiting rod 18. One end of the limiting sleeve 19 is connected to one end of the fixing block 12. In use, the mutual cooperation between the limiting rod 18 and the limiting sleeve 19 can limit the movement of the fixing block 12, making the fixing block 12 more stable when moving.

[0022] The adjustment mechanism includes a fixed rail 4, a movable block 5, a positioning hole 6, a mounting cavity 7, a positioning pin 8, and a telescopic spring 9. The fixed rail 4 is located on both sides of the mounting rod 1. The movable block 5 is disposed inside the fixed rail 4, and one end of the movable block 5 is connected to the inner side of the mounting block 2. The mounting cavity 7 is installed at one end of the mounting block 2. The positioning pin 8 is disposed through the interior of the mounting cavity 7, and one end of the positioning pin 8 extends into the interior of the positioning hole 6. The telescopic spring 9 is disposed on the outer wall of the positioning pin 8 and is installed inside the mounting cavity 7. The cross-section of the fixed rail 4 is larger than that of the movable block. In the cross-section of 5, the fixed rail 4 and the movable block 5 form a sliding structure. In use, the positioning pin 8 is pulled to disengage the positioning pin 8 from the positioning hole 6. Then, with the cooperation of the fixed rail 4 and the movable block 5, the movable mounting block 2 can be moved to adjust the hook 3 to an appropriate position. At this time, the positioning pin 8 is released, and the telescopic spring 9 is subjected to elastic force to drive the positioning pin 8 to extend, so that the positioning hole 6 and the positioning pin 8 are engaged with each other, completing the convenient fixation of the hook 3. This makes it less likely for the metal to interfere with each other during hot-dip galvanizing, thus making the hot-dip galvanizing effect of the metal better and greatly improving the versatility of the hanger in use.

[0023] Working principle: First, the operator pulls the positioning pin 8, disengaging it from the positioning hole 6. Then, with the cooperation of the fixed rail 4 and the movable block 5, the movable mounting block 2 adjusts the hook 3 to the appropriate position. At this point, the positioning pin 8 is released, and the telescopic spring 9, under its elastic force, extends the positioning pin 8, causing the positioning hole 6 and the positioning pin 8 to engage, thus easily fixing the hook 3. The metal to be hot-dip galvanized is then suspended on the hook 3 for hot-dip galvanizing. When the hook 3 needs to be replaced after prolonged use, the operator rotates the rotating wheel 13, causing the first bevel gear 14 to rotate. Due to the first bevel gear... The wheel 14 meshes with the second bevel gear 15, so the second bevel gear 15 drives the threaded rod 16 to rotate, which in turn drives the threaded sleeve 17 to move. Under the limit of the limit rod 18 and the limit sleeve 19, the threaded sleeve 17 drives the fixing block 12 to move, and the fixing block 12 is moved out of the fixing hole 11. At this time, the connecting block 10 can be taken out from the mounting block 2, the hook 3 can be removed, and then the new hook 3 can be taken out. The connecting block 10 is placed into the mounting block 2. At this time, the wheel 13 is rotated in the opposite direction, and the fixing block 12 is moved into the fixing hole 11 to fix the position of the hook 3, thus completing the installation of the hook 3.
