Access door construction for a hot water tank assembly

摘要

The present invention provides for an access door construction that is used with hot water tank assemblies that include an access opening in the inner tank and an access opening in the outer tank. The access door construction includes a first clamp that is interiorly located in the inner tank and is used to cover the first opening and a second clamp that is exteriorly located on the outer tank and is used to cover the second opening. A threaded rod is located between the first and second clamps to provide for the first and second clamps to be connect and to be a one piece structure. Centrally located on the first clamp is a circular groove while centrally located in the second clamp is a threaded through hole. The rod includes a handle at one end and a ball at its opposite end to provide for the ball to be located in the groove and for the opposite end extend through the hole. This design and configuration will permit for the ball end of the rod to rotate freely about groove and will enable the handle to move the second clamp towards or away from the outer tank. Once in place, the access door will provide for the first clamp to be securely fastened interiorly within the inner tank and the second clamp will be exteriorly secured to the outer tank.
