  However, in the above-mentioned conventional one, the gas plug (2) is a substantially L-shaped body in which the pipe connection portion extends at a right angle with respect to the plug cylinder (20), and the bottom wall of the casing (41) ( 4) Since it is configured to be fixed by screwing to a predetermined location that is deviated from the center of the gas stopper (5), depending on the direction of the connecting end of the gas pipe disposed in advance below the floor plate (5) When the orientation of 2) is determined, the orientation of the casing (41) for fixing the gas stopper (2) with respect to the opening (50) is determined. Then, the window part (52) is attached to the plug cylinder (20) of the gas stopper (2), and the open / close lid is in an upright position at the operation end part (23b) of the swing lever (23) attached to the plug cylinder (20). Since (54) must be made to correspond to each other, if the direction of the casing (41) is determined, the direction of the decorative plate (51) is also determined.

  Thus, in the conventional one, when the direction of the gas plug (2) is determined according to the direction of the connection end of the gas pipe, the direction of the casing (41) and the decorative plate (51) is determined respectively. The direction of the casing (41) and the decorative board (51) cannot be set freely. For this reason, for example, when a wall or furniture is located near the closing direction of the opening / closing lid (54), the opening / closing operation of the opening / closing lid (54) and the installation / removal operation of the socket (43) to the plug cylinder (20) There is a problem that it becomes difficult to do.

The present invention provides a bottomed casing that is embedded in an opening formed in a wall plate or a floor plate and opens toward the opening;

The plug cylinder is configured to be rotatable with respect to the bottom wall and held in a retaining state in a state where the plug cylinder is inserted into the hole from the outside of the casing. is there.

According to the above means, when the plug cylinder of the substantially L-shaped gas stopper is inserted from the outside into the hole provided in the bottom wall of the casing, the plug cylinder protrudes inward from the bottom wall of the casing and is connected to the pipe. The portion is arranged along the bottom wall outside the bottom wall of the casing. In this state, the base end portion of the plug cylinder is rotatable with respect to the bottom wall and attached in a retaining state. It is done.
The direction of the gas plug is determined so that the pipe connection portion of the gas plug faces in the direction in which the connection end portion of the gas pipe that is previously piped outside the casing located on the back side of the wall plate or floor plate is located. Since the plug cylinder is rotatable in the casing, the casing can be rotated with respect to the plug cylinder of the gas stopper whose orientation is fixed, and the orientation of the casing with respect to the gas stopper can be freely set to the opening. Can be attached. The decorative board can be attached in a predetermined direction according to the direction of the casing.

In the buried gas plug, preferably, “a portion of the plug cylinder that is located outside the bottom wall of the casing is provided with a large-diameter portion that is larger in diameter than the hole portion and protrudes to the inside of the casing. The locking ring is fitted on the body part in a retaining state,
The bottom wall is clamped from inside and outside of the casing by the large diameter portion and the locking ring.
In this structure, the locking ring and the large diameter portion function as a retaining means for fixing the plug cylinder to the hole provided in the bottom wall of the casing in a retaining state, and the bottom wall of the casing is connected to the locking ring. The direction of the gas stopper with respect to the casing can be fixed by clamping with the large diameter portion.

The orientation of the casing and the decorative plate with respect to the opening can be freely set in consideration of the distance between the housing and the furniture. Thereby, it is excellent in workability and can provide a user-friendly gas stopper.

  Further, in the case where the periphery of the hole provided in the bottom wall of the casing can be clamped by the locking ring provided in the plug cylinder and the large diameter portion, the direction of the gas stopper and the direction of the casing are respectively set to predetermined values. Since the gas stopper can be firmly fixed in the casing in the state set in the direction, there is no inconvenience that the gas stopper rattles due to vibration or the like. In particular, in the case of using screw tightening, the degree of fixing of the gas stopper to the casing is ensured, and if the screw is loosened, it becomes possible to relatively rotate the gas stopper or the casing. Usability is improved.

  In addition, when the hole is a round hole, an annular sealing member is provided between the cylindrical plug cylinder and the seal so that the plug cylinder and the casing rotate relative to each other. Even so, the confidential performance does not change, and the cold air behind the wall plate or floor plate does not flow into the room.
