Description

  The present invention relates to a spring-type inspection port lid that uses a wire spring as a structure for attaching a lid member for closing an inspection port provided on a wall surface.

  Conventionally, in order to inspect building equipment such as piping provided in a building, an inspection port is provided on the wall surface, and when inspection of piping etc. is completed, the inspection port is closed with a lid member. ing. As a conventional example of a device that closes such an inspection port, Patent Document 1 describes a structure using a bifurcated wire spring.

  In this apparatus, a main body case is fixed to a vent hole provided on a wall surface, and an opening of the main body case is covered with a grill. The structure is such that the lower locking member provided with a sliding plate for opening and closing the bifurcated wire spring is fixed to the grill, and the upper locking member engaged with the lower locking tool is fixed to the main body case. The wire spring is in an open state by pushing down the sliding plate with the upper locking member, and the grill is fixed to the main body case.

However, the structure of the above cited reference 1 includes a main body case fixed to the vent of the wall, a bifurcated wire spring attached to the back of the grille, a U-shaped lower locking tool attached to the grille, and a main body. Because it has a member such as a U-shaped upper locking device attached to the side wall of the case, it requires a large number of parts, and the sliding hole provided in the sliding plate has an opening at one end. During installation, the wire spring inserted into the sliding hole may come out of the opening, which is dangerous.
