Bearing races 7 are slidably sleeved on the suspension rod 3 at intervals from top to bottom. The first protective member 4 is arranged between the bearing races 7. The opposite raceways 71 of two adjacent bearing races 7 are in upper and lower contact with the two sealing ring surfaces of the first protective member 4.

[0028] The second protective member 5 is arranged on the upper side of the bearing race 7 at the highest position. The third protective member 6 is arranged on the lower side of the bearing race 7 at the lowest position. The upper nut 31 threadedly connected to the suspension rod 3 is arranged on the upper side of the second protective member 5. The lower nut 32 threadedly connected to the suspension rod 3 is arranged on the lower side of the third protective member 6. The second protective member 5 and the third protective member 6 are each provided with a sealing ring surface in contact with one raceway 71 of the adjacent bearing race 7.

[0029] The upper nut 31 is screwed on, and the lower nut 32 is brought closer, so that the second protective part 5, the bearing race 7, the first protective part 4, and the third protective part 6 are in close contact with each other, ensuring that each sealing ring surface is reliably and tightly fitted to the corresponding raceway 71.

[0030] As Figure 2 , Figure 3 shown, the installation process of this device is as follows: First, the lower nut 32 is threadedly connected to the bottom end of the suspension rod 3, and the third protective part 6 is sleeved on the suspension rod 3 and pressed against the upper side of the lower nut 32; the lower nut 32 serves to support the upper protective parts and the bearing race 7.

[0031] Then, a plurality of bearing races 7 and the first protective part 4 are sleeved on the suspension rod 3 in sequence, and each sealing ring surface is aligned and closely stacked with the corresponding raceway 71; the lower raceway 71 of the lowermost bearing race 7 is aligned and closely attached to the sealing ring surface of the third protective part 6; then, the second protective part 5 is sleeved on the suspension rod 3, and the upper raceway 71 of the uppermost bearing race 7 is aligned and closely attached to the sealing ring surface of the second protective part 5.

[0032] Finally, the upper nut 31 is threadedly connected to the top of the suspension rod 3, and the upper nut 31 is screwed. By relying on the upper nut 31 and the lower nut 32, the second protective part 5, the bearing race 7, the first protective part 4, and the third protective part 6 are clamped; the top of the suspension rod 3 is connected to the support rod 2, and the suspension rod 3 is suspended in the phosphating tank 1 by relying on the support rod 2. With this device, multiple bearing races 7 can be assembled at one time, and the sealing work of the raceways 71 of the bearing races 7 can be completed in batches, improving the phosphating efficiency of the bearing races 7.

[0033] Specifically, as Figure 4 shown, the first protective part 4 includes two annular support plates 41 spaced up and down. The center of the support plate 41 is slidably sleeved with the suspension rod 3; protective washers 42 are respectively arranged around the two support plates 41; the upper protective washer 42 is similar in shape to and fits the lower raceway 71 of the bearing race 7; the lower protective washer 42 is similar in shape to and fits the upper raceway 71 of the bearing race 7; the second protective part 5 and the third protective part 6 have the same structure. The second protective part 5 includes an annular support plate 41, and the center of the support plate 41 is slidably sleeved with the suspension rod 3; a protective washer 42 is arranged around the support plate 41; the protective washer 42 is similar in shape to the raceway 71, and the protective washer 42 closely fits the raceway 71. Preferably, a sealing ring is arranged on the fitting surface of the protective washer 42. After being squeezed, the sealing ring closely fits the raceway 71, improving the fitting tightness and preventing liquid from leaking in and damaging the raceway 71.

[0034] As Figure 2As shown in the figure, a guiding groove 11 is provided at the top of the pool wall of the phosphating tank 1; rollers 21 that roll along the guiding groove 11 are provided at both ends of the support rod 2. Preferably, a handle is provided at the end of the support rod 2; by pushing and pulling the handle, the support rod 2 moves along the guiding groove 11, and the support rod 2 drives the suspension rod 3 and its bearing race 7 to move horizontally in the phosphating tank 1, which is beneficial for the bearing race 7 to fully contact the liquid, fully react, and improve the phosphating efficiency.

[0035] As Figure 5 , Figure 6 As shown in the figure, the device further includes a strip plate 22, and through holes are spacedly provided on the strip plate 22; at least two support rods 2 are spacedly provided on the phosphating tank 1; a cross bar 23 is provided at the end of the support rod 2 extending outwards, and the through holes are sleeved on the cross bar 23. By reciprocally translating the strip plate 22, the strip plate 22 drives a plurality of support rods 2 to move synchronously; preferably, an automatic reciprocating telescopic rod for driving the strip plate 22 to translate is provided on one side of the phosphating tank 1 to replace manual operation and make the phosphating process automated.

[0036] As Figure 2 As shown in the figure, a detachable hook 33 is provided at the top of the suspension rod 3, and the hook 33 is hooked to the support rod 2. The hook 33 is connected to the top of the suspension rod 3 by threads or claws; the suspension rod 3 and the support rod 2 are connected by the hook 33, which is convenient for disassembly and assembly, and the rotation of the support rod 2 does not affect the hanging state of the suspension rod 3.

[0037] As Figure 4 As shown in the figure, the support plate 41 is provided with liquid through holes 411. During the phosphating process, the liquid flows through the liquid through holes 411, avoiding the protection member from hindering the liquid flow and enabling every part of the bearing race 7 to fully react.
