Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas plug socket removal structure for removing a socket connected to a plug portion of a gas plug installed on a wall surface or the like.

Conventionally, a gas valve having a plug portion for socket connection has a structure in which the valve opens when the socket provided at the tip of the pipe is connected to the plug portion, and closes when the plug portion is removed. .
A typical gas cock socket is provided with a forward/backward cylinder portion that advances and retracts in the axial direction according to attachment/detachment to/from the plug portion at the tip in the connection direction, and when the socket is connected to the plug portion, the forward/backward cylinder At the same time when the portion advances to the proximal end portion side of the plug portion, a lock mechanism provided in the socket operates to prevent the plug portion from being removed. By forcibly pushing the advance/retreat cylinder portion in the advanced state in the retreating direction, the locked state by the lock mechanism is released, and the socket can be removed from the plug portion.

The one shown in Patent Document 1 is a linear gas plug in which a pipe connection portion for connecting a flexible pipe via a joint and a plug portion for connecting a socket are positioned vertically along an axis, and are open vertically. It is used by being attached to a wall surface in a state housed in a case body. A movable member for removing the socket connected to the plug portion is provided in the case so as to be vertically slidable.
When the socket is connected to the plug through the open portion at the bottom of the case body, the advance/retreat cylinder portion advances upward, and the movable member is pushed from below by the advance end portion thereof, thereby sliding upward in the case body. At the same time, its upper end protrudes upward from the upper surface of the case body. This projecting portion serves as an operating portion for removing the socket from the plug portion.

To remove the socket from the plug portion, the operating portion projecting upward from the upper surface of the case body is pushed downward to slide the movable member downward. Then, the lower end of the movable member presses the advancing/retreating cylinder portion of the socket in the retreating direction, thereby releasing the locked state between the socket and the plug portion, and removing the socket from the plug portion.

In the above, there is provided locking means for locking the movable member in a retaining state.

The above means work as follows.
The gas plug main body fixed to the wall surface is covered with the covering case so that the tip of the plug portion faces the second opening side. In this state, the movable member interposed between the body of the gas plug main body and the covering case is urged toward the first opening of the covering case by the urging means, and the top surface of the operating portion, which is one end thereof, is urged toward the first opening of the covering case. is locked by the locking means so as to be held in a posture corresponding to the periphery of the first opening.
When the socket is inserted through the second opening of the cover case and connected to the plug portion, the advance/retreat cylindrical portion of the socket advances. Since the pressing portion, which is the other end of the movable member, is biased so as to be positioned closer to the first opening than the advancing end of the advancing/retreating tubular portion, there is no load on the advancement of the advancing/retreating tubular portion. , it can be connected to the plug part only by the mounting force of the socket itself.
To remove the socket, push the operation part in the first opening with a finger. Then, the movable member slides toward the second opening against the biasing force of the biasing means, and the pressing portion presses the forward/backward cylindrical portion of the socket in the retreating direction. As a result, the socket is disconnected from the plug portion and removed from the plug portion. Thereafter, when the finger is released from the operating portion, the movable member returns to the initial position where the top surface of the operating portion coincides with the peripheral edge of the first opening due to the biasing force of the biasing means.

In the above-described gas cock socket removing structure, it is preferable that "the operation part is a plate-like body having a size and shape that can be fitted in the first opening in a substantially close-fitting state,

It consists of a to-be-latched part.

A base end surface is formed on the side opposite to the plug portion side of the first trunk portion constituting the gas plug main body fixed to the wall surface, and is made to function as a spring receiver for the compression spring provided as the biasing means, There is no need to provide a separate spring receiving portion. It also functions as a push-in restricting portion that prevents the operation portion from being pushed deeper than necessary when the operation portion is pushed in. As a result, by pushing the operating portion inwardly of the first opening with a finger, the compression spring can be pushed in accurately while being elastically deformed, and the pushing portion of the movable member reliably pushes the advancing/retreating tubular portion of the socket. can be used to remove the socket from the plug. When a finger is released from the operating portion, the operating portion is urged toward the first opening together with the movable member by the elastic restoring force of the compression spring. In this state, the engaging projection provided on the movable member is engaged with the engaged portion provided on the inner surface of the covering case from the second opening side, and the top surface of the operating portion is positioned at the first opening of the covering case. It is held in a retaining state in a state of being positioned inside.

In the above-described gas cock socket detachment structure, it is preferable that the gas cock main body is a second barrel section that is continuous with the first barrel section in a direction perpendicular to the first barrel section and that can be inserted into an insertion hole provided in a wall surface. has
a fixing plate attached and fixed to the surface of the wall surface integrally protrudes in a direction perpendicular to the axis of the second body;
The cover case is provided with a back side open part, and in a state in which the plug part and the first body part are housed in the cover case from the back side open part, the open end peripheral edge of the back side open part is engaged with the fixing plate. It is possible to hold the same.

The first body and the plug portion are housed in the cover case from the back side open portion, and only by engaging and holding the peripheral edge of the back side open portion with the fixing plate, the cover case is the first plug portion including the plug portion. It becomes possible to easily fix to the wall surface in a state in which the body part is accommodated.

In the gas cock socket detachment structure, it is preferable that "the covering case includes a frame into which the fixing plate can be just fitted;
an arc-shaped inner surface continuously provided on the surface side of the frame portion, having the first and second openings open at both ends in the longitudinal direction, and surrounding the plug portion and the first body portion along the axis from the surface side; an enclosure having
A substrate provided near the first opening so as to partition the frame and the enclosing cylinder, and having a third opening into which the first body and the plug can be inserted and which opens toward the second opening. Consists of

In other words, since the forward/backward movement cylinder portion of the socket is not accidentally pressed in the retracting direction by the pressing portion, it is possible to prevent the socket from being detached from the plug portion.
Further, since the pressing portion is biased by the biasing means so that the pressing portion is positioned closer to the first opening side than the advancing end of the advancing/retracting cylinder portion of the socket connected to the plug portion, No load is applied from the movable member when the forward/backward movement cylinder part advances. Therefore, the socket can be connected to the plug portion without any trouble.
Further, after the pressing portion of the movable member presses the forward/backward cylindrical portion of the socket to remove the socket from the plug portion, the operating portion is returned to its original position corresponding to the periphery of the first opening by the biasing means, Since this state is configured to be held in a retaining state, it is possible to provide a convenient socket removal structure.
