Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Examples: an anode steel claw protecting ring, see fig. 1 and 2, comprises a protecting ring 1, a connecting shell 2 arranged on the outer wall of the protecting ring 1, an auxiliary plate 3 connected with the connecting shell 2, and a connecting block 4 for connecting the connecting shell 2. The protection ring 1 is a semicircular ring, and the number of the protection rings is two, and the protection rings can be spliced into a circular ring in pairs to protect anode steel claws.

The connecting shell 2 is formed by splicing two identical unit shells 21, the cross section of each unit shell 21 is semicircular, the two unit shells 21 can be spliced into a whole circle, and the protection ring 1 is arranged in the spliced whole circle. The connection housing 2 is provided outside the protection ring 1, and an inner wall of the connection housing 2 abuts against an outer wall of the protection ring 1. The connection shell 2 not only protects the protection rings 1, but also increases the stability of the connection between the two protection rings 1 by the connection between the connection shells 2.

One end of the unit housing 21 is fixedly connected with a projection 22, and the other end is provided with a groove 23 into which the projection 22 is inserted. By inserting the projection 22 into the groove 23, not only the connection stability between the two unit housings 21 but also the tightness of the connection between the unit housings 21 can be increased.

Both end portions of the unit case 21 are provided with connection grooves 24, and the connection grooves 24 allow the connection blocks 4 to be inserted. The connecting groove 24 has a trapezoidal shape, and an end near the outside is an end with a short bottom.
