[0002] In the process of immersion plating of workpieces, in order to improve their stability and avoid them from falling off, it is necessary to install and position the workpieces through hangers. However, the existing hangers mainly use more traditional fixing clamps to position them. This results in that when the workpieces are positioned through the fixing clamps, due to the large number of fixed points on the workpieces, the staff need to operate each fixing clamp one by one. Obviously, this will increase the operating time of the staff and reduce the work efficiency. For this reason, we propose a hanger for local immersion gold plating. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-5 The utility model provides a technical solution: a hanger for local immersion gold plating, comprising an immersion plating tank 1 and a hanger 11, the hanger 11 is plugged and installed on the upper side of the immersion plating tank 1, and sliding cavities 14 are opened on both sides of the inner cavity of the hanger 11, a plurality of positioning strips 12 are slidably installed in the hanger 11, and sliders 13 that slide with the sliding cavity 14 are fixedly installed at both ends of the positioning strips 12, and the sliding cavity 14 is provided with positioning grooves 2 on the upper and lower sides of the inner cavity of the sliding cavity 14, and positioning blocks 21 that are clamped with the positioning grooves 2 are slidably installed on the upper and lower sides of the inner cavity of the slider 13, and a first spring 23 is fixedly installed between the two positioning blocks 21, and a driving block 22 is rotatably installed in the slider 13.

[0024] Working principle: When the workpiece is dip-plated, the position of each positioning bar 12 is adjusted in the hanger 11 through the sliding cooperation between the slider 13 and the slide cavity 14, and the driving block 22 is rotated at the outer end of the slider 13. The rotating driving block 22 can push the positioning blocks 21 on both sides to move backwards through the contact effect between its periphery and the upper and lower positioning blocks 21, so that the two positioning blocks 21 are respectively fitted with the upper and lower ends of the positioning groove 2, so that the hanger 11 can be positioned in the hanger 11;

[0025] Then, each workpiece is inserted and installed between two adjacent positioning bars 12, and then, the hanger 11 is pressed downward to the upper end of the immersion plating tank 1, so that the lower end of the workpiece at the hanger 11 is immersed in the immersion plating tank 1, so as to achieve the effect of partial immersion plating of the workpiece;

[0026] The reverse rotation of the driving block 22 separates the outer end of the driving block 22 from the upper and lower positioning blocks 21 , thereby cooperating with the first spring 23 to drive the two positioning blocks 21 to return inward to the slider 13 , thereby facilitating readjustment of the position of the positioning bar 12 .

[0027] Example 2

[0028] A socket 15 is provided on the upper side of the outer periphery of the hanger 11, a plug rod 16 which is plugged into the socket 15 is fixedly installed on the outer periphery of the upper end surface of the immersion plating tank 1, a slide rod 25 is fixedly installed between the upper and lower end surfaces of the inner cavity of the slider 13, and a slide hole 24 which is plugged into the slide rod 25 is provided on the inner end surfaces of the two positioning blocks 21, and the first spring 23 is sleeved on the outer periphery of the slide rod 25.

[0029] Through the plug-in cooperation between the plug rod 16 and the plug hole 15, the movement direction of the hanger 11 can be restricted on the upper side of the immersion tank 1, ensuring that the lower part of the workpiece at the hanger 11 can be immersed in the immersion tank 1;

[0030] By plugging and fitting the sliding hole 24 and the sliding rod 25 , the movement direction of the upper and lower positioning blocks 21 can be restricted in the slider 13 , ensuring that the positioning blocks 21 can be stably fitted with the positioning grooves 2 , thereby ensuring the positioning effect of the hanger 11 .

[0031] Example 3

[0032] The driving block 22 is arranged in a spindle shape, and a positioning gear ring 3 is fixedly installed on the outer end surface of the slider 13, and a positioning gear plate 31 is inserted and installed in the positioning gear ring 3. The positioning gear plate 31 and the driving block 22 are plugged into each other, and a second spring 35 is fixedly installed between the two. A through cavity 32 is opened on the outer end surface of the driving block 22, and a movable plate 34 that slides with the through cavity 32 is fixedly installed on the inner end surface of the positioning gear plate 31 through a connecting rod 33. The second spring 35 is fixedly installed between the movable plate 34 and the through cavity 32, and the second spring 35 is sleeved on the outer periphery of the connecting rod 33.

[0033] When the position of the positioning block 21 is adjusted, the positioning tooth plate 31 is pulled outward in the positioning tooth ring 3 so that the two are separated from each other. Therefore, when the positioning tooth plate 31 is rotated, the sliding cooperation between the movable plate 34 and the through cavity 32 can drive the driving block 22 to rotate in the slider 13. Since the driving block 22 is arranged in a spindle shape, the rotating outer end of the driving block 22 can drive the positioning block 21 to move, so as to achieve the effect of positioning the hanger 11. Then the positioning tooth plate 31 is released, and under the action of the second spring 35 restoring the deformation, the movable plate 34 can be driven to reset, so that the positioning tooth plate 31 can be reinserted into the positioning tooth ring 3, thereby achieving the effect of positioning the driving block 22.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
