Base plate composite welding end socket with cathode anti-corrosion block

The utility model provides a base plate composite welding end socket with a cathode anti-corrosion block, and relates to the technical field of end socket devices. The welding tank sleeve is in a circular shape, a containing groove is formed in the middle of the welding tank sleeve, an annular clamping piece is arranged in the middle of the front end of the welding tank sleeve, a penetrating groove is formed in the middle of the annular clamping piece, the diameter of the penetrating groove of the annular clamping piece is smaller than that of the containing groove of the welding tank sleeve, and a composite sealing head is arranged in the penetrating groove of the annular clamping piece. The inclined plane position of the rear end of the hanging ring is welded with the inner position of the welding tank sleeve, and the composite sealing head and the welding tank sleeve are fixed, so that even if overlarge pressure exists in the welding tank sleeve and is transmitted to the composite sealing head, the front e
