Abstract
Description
Technical Field
[0001] This utility model relates to the field of cathode rods, and more specifically, to a cathode conductive rod. Background Technology
[0002] The cathode rod, or simply cathode rod, is a key component in electrochemical devices such as electrolytic cells.
[0003] To ensure the cathode rod remains stably and sustainably in the electrolyte, it is typically supported by hanging lugs. These lugs are usually fixed to the cathode rod by welding. However, since the cathode rod is immersed in the electrolyte for a long time and the lugs are not removable, the connection between the lugs and the cathode rod is prone to corrosion, which can affect the suspension effect of the cathode rod in the future.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cathode conductive rod.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cathode conductive rod, comprising a rod body and two lugs, wherein two insulating posts are fixedly connected to the rod body, and the two insulating posts have mounting grooves on the side facing away from the rod body. The cross-sectional shape of the mounting grooves is the same as the shape of the bottom surface of the lugs. The lugs have through holes, and the insulating posts are provided with fixing pins for passing through the through holes. The rod body is also provided with a plurality of contact posts, and all the contact posts and insulating posts are located on the same straight line on the outer peripheral wall of the rod body.
[0007] The present invention is further configured such that: two circular planes are provided on the rod body, a threaded hole is provided in the center of the plane, and a threaded post is provided on the side of the insulating post facing away from the mounting groove, which is screwed into the threaded hole.
[0008] The present invention is further configured such that: the insulating column includes an upper column and a lower column, the threaded column and the mounting groove are respectively located on the lower column and the upper column, and the upper column is rotatably connected to the lower column.
[0009] The present invention is further configured such that: the outer peripheral wall of the lower column is provided with vertically arranged friction ridges.
[0010] The present invention is further configured such that: a through hole is provided on the outer peripheral wall of the upper column, the fixing pin is located in the through hole, one end of the fixing pin is fixedly connected to a limit head, and the other end of the fixing pin is threadedly connected to a nut.
[0011] The present invention is further configured such that both the upper column and the lower column are made of ceramic.
[0012] In summary, this utility model has the following beneficial effects:
[0013] The lugs and the rod are insulated from each other, preventing current from flowing to the lugs. Metal lugs in direct contact with the rod are prone to galvanic corrosion due to potential differences, but the insulating post blocks this corrosion path, stabilizing the overall lifespan of the lugs. The lugs can be detached from the rod and replaced via a fixing pin, allowing for easy replacement after corrosion. The upper post is rotatably connected to the lower post, and the angle of the lugs can be adjusted according to actual needs, further improving installation convenience. Both the upper and lower posts are made of ceramic, which is high-strength and rust-free, ensuring the stability of their rotation. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] A cathode conductive rod, such as Figure 1 and Figure 2As shown, the device includes a rod body 1 and two lugs 2. Two insulating posts 3 are fixedly connected to the rod body 1. Mounting grooves 4 are formed on the side of the two insulating posts 3 facing away from the rod body 1. The cross-sectional shape of the mounting grooves 4 is the same as the shape of the bottom surface of the lugs 2. Through holes 5 are formed on the outer peripheral wall of the lugs 2, located near the lower end of the lugs 2. Fixing pins 6 for passing through the through holes 5 are provided on the insulating posts 3. Several contact posts 7 are also provided on the rod body 1. All contact posts 7 and insulating posts 3 are located on the same straight line on the outer peripheral wall of the rod body 1. The device is connected by connecting the power cathode to... The contact post 7 is connected, thus enabling the rod body 1 to be energized. There are two contact posts 7, and two insulating posts 3 are located between the two contact posts 7. The lug 2 and the rod body 1 are insulated by an insulator, so that the current will not flow to the lug 2. The metal lug 2 is in direct contact with the rod body 1, which is prone to galvanic corrosion due to potential difference. The insulating post 3 can block this corrosion path and stabilize the overall life of the lug 2. The lug 2 can be disassembled from the rod body 1 and replaced through the structure of the fixing pin 6, so that the lug 2 can be replaced after being corroded.
[0020] like Figure 2 and Figure 3 As shown, the rod body 1 has two circular planes 8, with a threaded hole 9 at the center of each plane 8. The insulating post 3 has a threaded post 10 screwed into the threaded hole 9 on the side facing away from the mounting groove 4. This threaded connection ensures both the strength of the fixed connection between the insulating post 3 and the rod body 1 and facilitates the connection. Furthermore, the plane 8 structure provides a large contact area between the insulating post 3 and the rod body 1, facilitating the locking of the threaded structure. The insulating post 3 includes an upper post 11 and a lower post 12. The threaded post 10 and the mounting groove 4 are located on the lower post 12 and upper post 11, respectively. The upper post 11 is rotatably connected to the lower post 12. The angle of the hanging lug 2 can be adjusted according to actual needs, further improving installation convenience. Both the upper post 11 and the lower post 12 are made of ceramic, which has high strength and does not rust. To ensure the stability of the rotation of both, the outer peripheral wall of the lower column 12 is provided with vertically arranged friction ridges. The friction ridges increase the friction coefficient of the outer peripheral wall of the lower column 12, making it easier for people to tighten the lower column 12 into the threaded hole 9. The outer peripheral wall of the upper column 11 is provided with a through hole, and the fixing pin 6 is located in the through hole. One end of the fixing pin 6 is fixedly connected to the limiting head 13, and the other end of the fixing pin 6 is threadedly connected to the nut 14. After the fixing pin 6 is inserted into the through hole and passes through the through hole 5 on the hanging ear 2, the diameter of the limiting head 13 is larger than the diameter of the through hole, so that the limiting head 13 cannot enter the through hole. With the tightening structure of the nut 14, the hanging ear 2 can be fixed. The mounting groove 4 matches the bottom shape of the hanging ear 2. Combined with the design of the fixing pin 6 passing through the through hole 5, the hanging ear 2 can be stably installed on the insulating column 3.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
