[0002] Expansion bolts are a special threaded connector used to fix pipes or equipment to walls, floors, and columns. Expansion bolts are prone to corrosion during daily use. In order to extend the service life of expansion bolts, they need to be electroplated.

[0003] In the prior art, when electroplating expansion bolts, it is generally necessary to pre-process the expansion bolts and then place them in a holding box. The holding box is then placed in an electroplating tank for electroplating. However, there are some problems in its use. After the expansion bolts are electroplated, there is some electroplating liquid in the holding box. If the electroplating liquid remains in the holding box, it will cause waste. If the holding box is lifted and waiting for the electroplating liquid to be controlled out, it will affect work efficiency.

[0004] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0024] The utility model provides Figure 1-5 The illustrated device is a highly efficient electroplating device for expansion bolts, comprising an electroplating tank 1 containing an electroplating solution, an electroplating mechanism mounted on the electroplating tank 1, and a supporting mechanism. The electroplating mechanism comprises a plurality of holding racks 2 rotatably mounted in the electroplating tank 1, the holding racks 2 being mounted with a plurality of hoisting rods 3, a holding box containing expansion bolts being hung on the hoisting rods 3 via a hoisting device, a driving rack 4 being mounted on the electroplating tank 1, and the driving rack 4 being capable of driving the holding racks 2 to rotate. The supporting mechanism comprises a plurality of support rods 5 mounted on both sides of the lower end of the electroplating tank 1, a sliding rack 6 being mounted on the upper ends of the support rods 5, and the support rods 5 being capable of supporting the holding racks 2.

[0025] The process of electroplating expansion bolts by this device is as follows: the processed expansion bolts are placed in a holding box, and the holding box can be hoisted to a hoisting rod 3 on the holding rack 2 by a hoisting frame. When all the holding racks 2 have holding boxes, the holding rack 2 is driven to rotate by the driving frame 4, so that the holding box can enter the electroplating liquid under the electroplating tank 1, and then the expansion bolts can be electroplated. During electroplating, the second batch of holding boxes are placed on the second hoisting rod 3 on the holding rack 2 by the hoisting frame, and then the holding rack 2 is driven to rotate by the driving frame 4, so that the two holding boxes can be placed on the second hoisting rod 3 on the holding rack 2. The boxes are all in the electroplating solution for electroplating. After a period of time, the third batch of holding boxes are placed on the third hoisting rod 3 on the holding rack 2 through the hoisting rack, and then the holding rack 2 is driven to rotate by the driving rack 4, so that the second batch of holding boxes and the third batch of holding boxes enter the bottom of the galvanizing solution for electroplating, and the first batch of holding boxes are moved to the top of the electroplating solution, so that the electroplating liquid can be controlled out. In addition, since there are already two holding boxes at the lower end of the holding rack 2, the driving rack 4 can be more labor-saving. When the expansion bolts in the holding boxes are electroplated, the support rod 5 and the sliding rack 6 can support the holding rack 2.

[0026] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 and instructions attached Figure 3 The holding rack 2 includes a rotating disk 7 located in the electroplating pool 1, a rotating shaft 8 is installed on the rotating disk 7, and rolling bearings 9 are installed at both ends of the rotating shaft 8. The rolling bearings 9 are installed on the inner surface of the electroplating pool 1. The rotating disk 7 can rotate around the rotating shaft 8, thereby facilitating the movement of the holding box.

[0027] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 , Instruction Manual Figure 3 and instructions attached Figure 5 The drive frame 4 includes a brake servo motor 10 installed on the electroplating tank 1, a first sprocket 11 is installed on the rotating end of the brake servo motor 10, a second sprocket 12 is installed on one end of a rotating shaft 8, the first sprocket 11 and the second sprocket 12 are connected by a first transmission chain 13, a third sprocket 14 is installed on one end of the rotating shaft 8, and adjacent third sprockets 14 are connected by a second transmission chain 15;

[0028] The process of the driving frame 14 driving the holding frame 2 to rotate is as follows: the brake servo motor 10 is started to rotate, and the brake servo motor 10 can drive the first sprocket 11 to rotate. The first sprocket 11 and the second sprocket 12 are connected by the first transmission chain 13, which can drive the second sprocket 12 and a rotating shaft 8 to rotate. The third sprocket 14 on the adjacent rotating shaft 8 is connected by the second transmission chain 15, which can drive all the rotating shafts 8 to rotate and make the rotating disk 7 rotate.

[0029] Refer to the instruction manual Figure 1 and instructions attached Figure 2 A plurality of lifting rods 3 are evenly distributed on the rotating disk 7 with the rotating shaft 8 as the center. A circular groove 16 is opened on the lifting rod 3, and a rotating sleeve 17 is mounted on the outer side of the circular groove 16. The circular groove 16 can limit the rotating sleeve 17 to prevent the rotating sleeve 17 from falling. When the container is hung on the rotating sleeve 17, the rotation of the rotating disk 7 can drive the lifting rod 3 to rotate. The lifting rod 3 can rotate relatively inside the rotating sleeve 17, thereby ensuring that the container remains in a vertical state.

[0030] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 and instructions attached Figure 4 The support rod 5 is located below the rotating shaft 8, and the sliding frame 6 includes a support platform 18 installed at the upper end of the support rod 5.
