[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] The utility model provides two technical schemes:

[0025] Figures 1 to 5 The first embodiment is shown: a kind of flange hanger for electroplating processing flange, including main hanger 1, hook 2 is fixed symmetrically in main hanger 1 top, several racks 3 are fixed in main hanger 1 top, several vice hangers 4 are detachably installed in rack 3 top, several hooks 5 for hanging flange are fixed at equal intervals on one side of vice hanger 4;

[0026] Vice hanger 4 is installed with lifting assembly that flange is lifted from hook 5 and then flange can be evenly electroplated.

[0027] Rack 3 is provided with insertion hole 6 at equal intervals for inserting vice hanger 4, and reinforcing sleeve 7 is fixed at the position corresponding to several insertion holes 6 in rack 3 top.

[0028] Lifting assembly includes lifting block 8 slidingly connected to the inner wall of hook 5, one connecting rod 9 is fixed to the end of the plurality of lifting blocks 8 away from hook 5 and penetrates vice hanger 4, lifting block 8 is slidingly connected to the inner wall of vice hanger 4, and the lower end of connecting rod 9 extends below the lowest point of main hanger 1.

[0029] The application sets lifting assembly, effectively avoids the problem that electroplating is uneven due to the contact between flange and hook 5, by placing main hanger 1 below electroplating tank, the lower end of connecting rod 9 abuts against the lowest point of electroplating tank, so that connecting rod 9 is pushed up to lift lifting block 8, and then flange is lifted from hook 5, so that flange can be contacted with electroplating solution in all directions and evenly in electroplating solution, effectively avoiding the problem of uneven electroplating caused by local contact, and improving the electroplating quality.

[0030] Two stabilizing sleeves 10 are symmetrically fixed to the end of vice hanger 4 close to connecting rod 9, and connecting rod 9 is slidingly connected to the inner wall of stabilizing sleeve 10.

[0031] Figures 1 to 2 The second embodiment is shown, and the main difference from the first embodiment is that:

[0032] The upper edge of the reinforcing sleeve 7 is provided with a rounded corner, and the auxiliary hanger 4 is in sliding connection with the inner wall of the reinforcing sleeve 7.

[0033] The reinforcing sleeve 7 enhances the structural strength of the connecting part between the auxiliary hanger 4 and the placing rack 3, reduces the risk of damage to the connecting part due to shaking or weight during electroplating, and improves the stability and durability of the hanger as a whole; the upper edge of the reinforcing sleeve 7 is provided with a rounded corner, which facilitates the insertion of the auxiliary hanger 4 into the insertion hole 6.

[0034] Working principle:

[0035] When the hanger is used for electroplating of the flange plate, the flange plate is first hung on the hook 5 on one side of the auxiliary hanger 4 through the hole thereof; then, the main hanger 1 with the assembled auxiliary hanger 4 is moved to above the electroplating tank through the upper fixed hook 2, and the main hanger 1 is placed into the electroplating tank to make the flange plate perform electroplating work; when the lower end of the connecting rod 9 below the main hanger 1 abuts against the lowest point of the electroplating tank, the connecting rod 9 abuts against the bottom of the electroplating tank, generating an upward force, so that the connecting rod 9 is driven to move on the inner wall of the stabilizing sleeve 10, and the plurality of lifting blocks 8 are driven to slide upward along the length direction of the auxiliary hanger 4 in the inner wall of the hook 5, thereby lifting the flange plate hung on the hook 5, so that the flange plate can be in full and uniform contact with the electroplating solution in the electroplating solution, effectively avoiding the problem of uneven electroplating caused by local contact, and ensuring the electroplating quality.

[0036] Since the auxiliary hanger 4 is detachably placed on the placing rack 3 through the insertion hole 6, the model of the auxiliary hanger 4 and the spacing of each auxiliary hanger 4 can be selected according to the thickness of the flange plate, thereby improving the applicability of the device.
