Disclosed is an electrolytic bath body with a protective function. The electrolytic bath body with the protective function comprises an electrolytic bath. A first electrode plate and a second electrode plate are arranged on the left side and the right side of an inner cavity of the electrolytic bath correspondingly. A first protective plate and a second protective plate are arranged on the left side of the upper end of the first electrode plate and the right side of the upper end of the second electrode plate, and the right end of the first protective plate and the left end of the second protective plate are connected through a clamping groove. Sliding rails are arranged at the upper end of the first protective plate and the upper end of the second protective plate, and a sliding groove isformed in the middle of each sliding rail. Rectangular grooves are formed in the right side of the upper end of the first protective plate and the left side of the upper end of the second protectiveplate, and the middle of the portion located between the sliding rails is connected with a scraping plate through a connecting shaft. According to the electrolytic bath body with the protective function, due to the structure with the first protective plate and the second protective plate, the working safety factor of the electrolytic bath is greatly improved; and due to the structure with the scraping plate, cleaning of the upper surface of the first protective plate and the upper surface of the second protective plate is guaranteed.
