Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, the present utility model provides a technical solution: the utility model provides a novel electrode pole, including water-cooling joint 1, and threaded connection is at the body of rod 2 of water-cooling joint 1 one end, the inside of body of rod 2 is equipped with cavity 9, the inside fixedly connected with exchange plate 7 of cavity 9, exchange plate 7 not only can increase the area of contact of cooling water with body of rod 2, and be in the inside cooling water of water pipe 10 can directly cool off body of rod 2 through exchange plate 7, and then the cooling efficiency of cooling water has been improved, a plurality of contact holes 8 have been seted up in the surface run-through of exchange plate 7, contact hole 8 can be convenient for cooling water flow exchange plate 7, discharge from water joint 6, and a plurality of contact holes 8 are annular equidistance and distribute, the internally mounted of water-cooling joint 1 has water pipe 10, the middle part of exchange plate 7 is equipped with through-hole 11, through-hole 11 can be convenient for water pipe 10 to pass exchange plate 7.

Wherein, electrode 3 is installed to the one end of body of rod 2, and electrode 3 passes through threaded connection at the inner wall of body of rod 2, and the convenience of customers installs electrode 3.

Wherein, the electrode cap 4 is installed to the one end of electrode 3 far away from body of rod 2, and electrode cap 4 installs on electrode 3 with threaded connection's mode to the user's change electrode cap 4 of being convenient for.

Wherein one end of the water pipe 10 extends through the rod body 2 to the inside of the electrode 3.

Wherein, water-cooling joint 1's bottom left side is installed water inlet joint 5 and water outlet joint 6 to the right side in proper order, and water inlet joint 5 is used for letting in low temperature cooling water to water pipe 10 in, and water outlet joint 6 is used for discharging the cooling water that the temperature risees, and water inlet joint 5 and water pipe 10 intercommunication, water outlet joint 6 and cavity 9 intercommunication.
