Abstract: The present invention discloses a closed-conical steel barrel closed hoop type crimping type closure for a detachable bucket top cover in the field of packaging steel drums, which is sealed, clamped and manufactured. The closure device of the invention has the closed technical steel drum with all the technical properties of the closed cylindrical steel barrel, and can open the closing device when necessary, and take off the closed cone barrel top cover, and use it as a full-opening tapered steel barrel. The closure device of the invention uses the O-ring sealing and self-sealing principle to form a fixed sealing groove space between the annular circular groove of the barrel top cover and the bead edge of the barrel mouth, and the O-ring is formed when the crimping type closing device is clamped. The barrel top cover is sealed to the barrel opening by the resilience generated by compression when entering the sealing groove. When the closed cone steel barrel is transported for long distance, the top cover of the barrel can be taken down, and the barrel body can be stacked and stacked, which can save 70% of the transportation cost. When the old steel barrel is cleaned and repaired, the top cover of the barrel is removed, and the cleaning equipment is cleaned. Direct access to the barrel can save 50% cleaning and repair costs.
Main Claim: A closed hoop crimping type closure comprising a top cover 3, an O-ring 11, a multi-tubular bead 13 and a crimping closure hoop 1. The utility model is characterized in that: the crimping type closed device can fix the closed steel barrel top cover 3 on the barrel of the full-opening tapered steel barrel 7, so that the full-opening tapered steel barrel has the technical performance of the closed cylindrical steel barrel, and the full opening Conical steel drums can be used as closed steel drums. When the closed conical steel drum is repaired and repaired by long-distance transportation, the crimping type hoop can be opened, the top cover of the barrel can be removed, and the closed conical steel barrel is converted into a full-open conical steel barrel.
