[0006] The utility model provides the following technical solution: A hanger for aluminum profile oxidation coloring includes a hanging rod. A suspension head is welded and fixed at the top of the hanging rod. A lower fixing disk is slidably sleeved on the outer wall of the hanging rod. An upper fixing disk is fixedly sleeved on the outer wall of the end of the hanging rod away from the lower fixing disk. A fixing device is provided at the bottom of the hanging rod.

[0007] The lower fixed disk includes a positioning rod and a telescopic rod. When the positioning rod is squeezed, the telescopic rod is compressed and shrinks.

[0008] The fixing device includes an adjusting screw and a pin. When the adjusting screw rotates, it drives the pin to extend from the inner wall of the hanging rod.

[0009] As a preferred technical solution of the present invention, the lower fixed disk further includes a fixed seat. The inner wall of the fixed seat is slidably connected to the outer wall of the hanging rod. A disk is fixedly welded to the top of the fixed seat. The inner wall of the positioning rod is fixedly welded to both ends of the telescopic rod. A buffer spring is slidably sleeved on the outer wall of the telescopic rod.

[0010] As a preferred technical solution of the present invention, a chute is opened on the top of the disk, and the inner wall of the chute is slidably connected to the bottom of the positioning rod. Both ends of the buffer spring are respectively fixedly connected to the two positioning rods, and the upper fixed disk and the lower fixed disk have the same structure.

[0011] As a preferred technical solution of the present invention, one end of the adjusting screw is inserted into the inner wall of the hanging rod and is rotatably connected to the inner wall of the hanging rod. A tapered sleeve is threadedly connected to the outer edge of the adjusting screw. The outer wall of the tapered sleeve is slidably connected to the inner wall of the hanging rod. A pin is slidably connected to the inner wall of the hanging rod. A return spring is slidably sleeved on the outer wall of the pin.

[0012] As a preferred technical solution of the present invention, limiting circular blocks are fixedly welded to both ends of the pin, and the return spring is sleeved on the outer wall of the part of the pin located in the inner cavity of the hanging rod.

[0013] As a preferred technical solution of the present invention, a limiting block is fixedly welded to the outer wall of the tapered sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. For the hanging tool for aluminum profile oxidation coloring, by manually rotating the adjusting screw, the tapered sleeve threadedly connected to the outer edge of the adjusting screw is driven to move. During the movement of the tapered sleeve, the tapered sleeve squeezes the pin, so that the pin moves under force and extends from the inner wall of the hanging rod. By using the clamping groove opened on the outer wall of the fixed seat, the pin can enter the clamping groove opened in the fixed seat when moving, realizing the fixed limit of the fixed seat and realizing the adjustment of the position between the lower fixed disk and the upper fixed disk, which is convenient for clamping and fixing circular workpieces of different lengths.

[0025] 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 of 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.

[0026] Please refer to Figure 1, a hanger for aluminum profile oxidation coloring, including a hanging rod 1. A suspension head 2 is welded and fixed at the top of the hanging rod 1. A lower fixing plate 3 is slidably sleeved on the outer wall of the hanging rod 1. An upper fixing plate 4 is fixedly sleeved on the outer wall of one end of the hanging rod 1 away from the lower fixing plate 3. A fixing device 5 is arranged at the bottom of the hanging rod 1;

[0027] The lower fixing plate 3 includes a positioning rod 303 and a telescopic rod 304. When the positioning rod 303 is squeezed, the telescopic rod 304 is compressed and shrinks;

[0028] The fixing device 5 includes an adjusting screw 501 and a pin 504. When the adjusting screw 501 rotates, it drives the pin 504 to protrude from the inner wall of the hanging rod 1.

[0029] As Figure 4 , Figure 5 and Figure 6 shown, the lower fixing plate 3 further includes a fixing seat 301. The inner wall of the fixing seat 301 is slidably connected to the outer wall of the hanging rod 1. A disc 302 is welded and fixed at the top of the fixing seat 301. The inner walls of the positioning rods 303 are welded and fixed to both ends of the telescopic rod 304. A buffer spring 305 is slidably sleeved on the outer wall of the telescopic rod 304. The positioning rod 303 is squeezed inward, so that the two positioning rods 303 squeeze the telescopic rod 304 and the buffer spring 305. The telescopic rod 304 and the buffer spring 305 are stressed and shrunk, and the elastic potential energy of the buffer spring 305 is increased. Then one end of the positioning rod 303 is inserted into the port of the circular workpiece, and the extrusion on the positioning rod 303 is released. The elastic potential energy of the buffer spring 305 is used to push the two positioning rods 303 outward, so that the positioning rods 303 are in contact with the inner wall of the circular workpiece and are tightened.

[0030] As Figure 5 and Figure 6 shown, a chute is opened at the top of the disc 302, and the inner wall of the chute is slidably connected to the bottom of the positioning rod 303. Both ends of the buffer spring 305 are fixedly connected to the two positioning rods 303 respectively, and the upper fixing plate 4 and the lower fixing plate 3 have the same structure, which reduces the friction loss between the positioning rod 303 and the disc 302, and can limit the positioning rod 303. The upper fixing plate 4 and the lower fixing plate 3 are used to fix both ends of the circular workpiece to maintain stability during the coloring process.

[0031] As Figure 2 and Figure 4As shown in the figure, one end of the adjusting screw rod 501 is inserted into the inner wall of the hanging rod 1 and is rotatably connected to the inner wall of the hanging rod 1. A conical sleeve 502 is threadedly connected along the outer side of the adjusting screw rod 501. The outer wall of the conical sleeve 502 is slidably connected to the inner wall of the hanging rod 1. A latch 504 is slidably connected to the inner wall of the hanging rod 1. A return spring 505 is slidably sleeved on the outer wall of the latch 504. Manually rotate the adjusting screw rod 501 to drive the conical sleeve 502 threadedly connected along the outer edge of the adjusting screw rod 501 to move. During the movement of the conical sleeve 502, the conical sleeve 502 presses the latch 504, causing the latch 504 to move under force and extend from the inner wall of the hanging rod 1. By using the card slot opened on the outer wall of the fixing seat 301, the latch 504 can enter the card slot opened in the fixing seat 301 when it moves, realizing the fixed limit of the fixing seat 301.

[0032] As Figure 4 shown, limiting circular blocks are welded and fixed at both ends of the latch 504. The return spring 505 is sleeved on the outer wall of the part of the latch 504 located in the inner cavity of the hanging rod 1. By using the limiting circular blocks provided at both ends of the latch 504, the latch 504 is prevented from separating from the inner wall of the hanging rod 1.

[0033] As Figure 2 shown, a limiting block 503 is welded and fixed on the outer wall of the conical sleeve 502. A limiting groove is opened at the position where the inner wall of the hanging rod 1 is connected to the limiting block 503, and the inner wall of the limiting groove is slidably connected to the outer wall of the limiting block 503. Both ends of the conical sleeve 502 are conical. When the conical sleeve 502 slides, it drives the limiting block 503 to slide in the limiting groove. By using the cooperation of the limiting block 503 and the limiting groove, the conical sleeve 502 can be kept moving straight up and down.

[0034] As Figure 4 shown, a card slot is opened on the outer wall of the fixing seat 301, and the inner wall of the card slot is slidably connected to the outer wall of the latch 504. The latch 504 can enter the card slot opened in the fixing seat 301 when it moves, fixing the fixing seat 301 on the outer wall of the hanging rod 1, facilitating the fixing or disassembly of the fixing seat 301.

[0035] Working principle: When in use, manually rotate the adjusting screw rod 501 to drive the conical sleeve 502 threadedly connected to the outer edge of the adjusting screw rod 501 to move. During the movement of the conical sleeve 502, the conical sleeve 502 squeezes the pin 504, causing the pin 504 to move under force and extend from the inner wall of the hanging rod 1. By using the card slot opened on the outer wall of the fixing seat 301, the pin 504 can enter the card slot opened in the fixing seat 301 when moving, realizing the fixed limit of the fixing seat 301 and the adjustment of the position between the lower fixed disk 3 and the upper fixed disk 4. Then, squeeze the positioning rod 303 inward, causing the two positioning rods 303 to squeeze the telescopic rod 304 and the buffer spring 305. The telescopic rod 304 and the buffer spring 305 contract under force, and the elastic potential energy of the buffer spring 305 increases. Then, insert one end of the positioning rod 303 into the port of the circular workpiece, release the extrusion on the positioning rod 303, and use the elastic potential energy of the buffer spring 305 to push the two positioning rods 303 outward, making the positioning rods 303 abut against the inner wall of the circular workpiece, achieving the purpose of clamping workpieces with different diameters. Finally, hang the device and the workpiece to the corresponding position through the hanging head 2 for coloring treatment.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
