[0026] The setting of the fixed structure is conducive to the stable operation of the overall structure, improves the structural stability, and thus ensures the electroplating efficiency.

[0027] It should be noted that the fixed structure includes a connecting plate 6 fixed to the bottom of the connecting rod 5, a slide groove 7 opened on the connecting plate 3, a slider 8 slidably connected to the slide groove 7, a connecting rod 9 fixed to the bottom of the slider 8 and a suspension frame 10 fixed between the four connecting rods 9, and the bottom of the connecting plate 6 is fixed to six groups of fixed plates 11.

[0029] Furthermore, the suspension frame 10 includes an outer frame 1001 fixed to the connecting rod 9, and a suspension mesh 1002 is fixed on the inner side of the outer frame 1001. By arranging the suspension mesh 1002 between the outer frames 1001, it is beneficial to the penetration of the plating liquid during immersion, ensuring the stable progress of the immersion work and facilitating the stability of the hanger.

[0030] It can be understood that six groups of two fixing plates 11 are fixed to the bottom of the fixed structure, a seat 12 is fixed between each group of fixing plates 11, a fixing assembly 13 for frame fixing is provided on the middle and front seat 12, a rotating assembly 14 located in the fixing assembly 13 and used for transmission is provided on the front of the seat 12, a disc 15 is fixed to the bottom of the rotating assembly 14, a handle 16 is fixed to the outer surface of the disc 15, a fixing seat 17 is fixed to the bottom of the top plate 4, a notch matching the handle 16 is provided on the fixing seat 17, a first support rod 18 and a second support rod 19 are respectively fixed between the front and rear fixing assemblies 13, and two transmission plates 20 are fixed between two fixing assemblies 13 adjacent in the horizontal direction.

[0031] In this embodiment, multiple fixing components 13 are associated, the frame is fixed by the fixing components 13, and the entire hanger is moved downward until the frame is immersed in the electroplating liquid, thereby realizing the function of electroplating frames of different specifications, which is beneficial to improving convenience and accelerating electroplating efficiency.

[0032] See also Figures 3 to 4 In order to improve the convenience of the hanger, the fixing component 13 in this embodiment includes an extension plate 1301 and an extrusion block 1304 and a stretching block 1305 movably connected to the top of the support seat 12. The left and right sides of the back side of the extension plate 1301 are fixed with movable rods 1302 that pass through the extrusion block 1304 and the stretching block 1305 in sequence and are slidably connected to the two. The outer surface of the movable rod 1302 is wrapped with a spring 1303 whose two ends are respectively fixed to the extrusion block 1304 and the stretching block 1305. The setting of the spring 1303 helps to reset the extrusion block 1304 and the stretching block 1305, which is beneficial to the stable operation of the fixing component 13, thereby improving the stability of the hanger.

[0033] It can be understood that the front transmission plate 20 is fixed to the left and right extrusion blocks 1304, the back transmission plate 20 is fixed to the left and right stretching blocks 1305, the front and rear ends of the first support rod 18 are respectively fixed to the extrusion blocks 1304 on the front and rear fixing components 13, the front and rear ends of the second support rod 19 are respectively fixed to the stretching blocks 1305 on the front and rear fixing components 13, and the opposite side of the extrusion block 1304 and the stretching block 1305 is fixed with an L-shaped limiting plate 1306 with the bottom extending to the outside of the support 12, and the two adjacent extrusion blocks 1304 and stretching blocks 1305 in the horizontal direction are respectively fixed to the corresponding transmission plate 20.

[0034] Therefore, it can be known that the arrangement of the first support rod 18, the second support rod 19 and the transmission plate 20 is conducive to linking the extrusion block 1304 and the stretching block 1305 between the fixed components 13, thereby driving the fixed components 13 on the horizontal sides and a group of three fixed components 13 at the rear to be linked by the fixed component 13 in the middle of the front, which is conducive to improving the immersion efficiency of the frame, thereby improving production efficiency.

[0035] In addition, an opening is provided in the middle of the support 12 for the displacement of the limit plate 1306, and the top of the opening is connected to two through grooves opened on the support 12 and adapted to the extrusion block 1304 and the stretching block 1305. The setting of the opening and the through groove is beneficial to the stable operation of the extrusion block 1304 and the stretching block 1305, and is beneficial to improving the stability of the hanger. A limit column is fixed to one end of the movable rod 1302 close to the stretching block 1305. The setting of the limit column is beneficial to ensuring the displacement movement of the stretching block 1305, thereby improving the stability of the hanger.

[0036] Furthermore, the rotating component 14 includes a fixed plate 1401 fixed to the front side of the support 12, and the inner side of the fixed plate 1401 is rotatably connected to a fixed column 1402 that penetrates the fixed plate 1401 and is fixed to the disc 15, and the outer surface of the fixed column 1402 is fixed with a brake block 1403 located above the fixed plate 1401, and the front and rear sides of the brake block 1403 are respectively fitted with the extension plate 1301 and the extrusion block 1304, and the brake block 1403 is an irregular structure with arcs on the left and right sides and depressions on the front and rear sides. This irregular structural setting helps to reduce the friction caused by the rotation of the handle 16, thereby making the fixed component 13 run more stably, which is beneficial to the operation of the dipping work, thereby ensuring the stability of the work.

[0037] In this embodiment, through the cooperation between the fixing component 13 and the rotating component 14, the frame is fixed between the limiting plates 1306 under the rotation of the handle 16, which is beneficial to fix frames of different specifications, thereby ensuring the completion of the subsequent immersion process, improving the convenience of the hanger, and helping to improve the electroplating efficiency.

[0038] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0039] The working principle of the above embodiment is:

[0040] Fill the liquid container 2 with the plating liquid, place the frame on the hanging frame 10 and through the opening of the support seat 12, and then place the frame between the limit plates 1306. After placing the frame, push the handle 16 to drive the brake block 1403 to rotate. Under the structural action of the brake block 1403, the extension plate 1301 moves forward, driving the movable rod 1302 to move forward, thereby causing the stretching block 1305 to move forward, and the extrusion block 1304 moves backward, thereby causing the limit plate 1306 at the bottom to move relatively, fixing the frame placed in the middle. At the same time, the fixing action of the first support rod 18 and the second support rod 19 drives the extrusion block 1304 and the stretching block 1305 on the back of the three fixing components 13. 5 synchronously moves, and under the driving action of the transmission plate 20, the squeezing blocks 1304 and the stretching blocks 1305 on the fixing components 13 on both sides of the horizontal are also linked, so as to fix the frame, and realize the simultaneous clamping and fixing of the six fixing components 13. When the frame is fixed, the handle 16 is inserted into the fixing seat 17, and the electric push rod is connected to the connecting rod 5 to make the limit plate 1306 and the hanging frame 10 slide along the direction of the slide groove 7 under the sliding action of the slider 8, until the frame between the limit plates 1306 is immersed in the electroplating liquid, thereby completing the immersion of the frame. The overall structure is simple, so that the hanger can effectively fix multiple frames at one time, improve the fixing efficiency of the hanger, and further help to improve production efficiency.
