Description

[Detailed Description of the Invention] The present invention relates to a socket removal device used in a gas tank, and in particular, a sliding plate is provided on the side of the main body and this is interlocked with an operating knob, and a member interlocking with the sliding plate is used. This invention relates to a socket removal device for a gas tank, which allows the socket to be removed.

As this type of socket removal device, one disclosed in Japanese Utility Model Application Publication No. 54-62123 has already been proposed.

In this device, a release knob configured separately from the operating knob of the Kotoku is disposed coaxially with the operating knob, and this release knob and a sliding plate provided on the side of the Kotuku body are interlocked. A frame body that operates obliquely is connected to the tip of this sliding plate, and this frame body is arranged around the outer periphery of the plug provided on the Kotuku body, and this frame body moves horizontally diagonally with respect to the Kotoku body. This is a pairing.

In this device, when the socket is connected to the plug, the actuating tube (the tube that protrudes when the socket is connected to the plug) provided on the socket protrudes, the frame body lowers diagonally, and the sliding plate moves along with this. It is moved horizontally by a certain amount, and the locking device that had previously locked the operating knob in an inoperable state is released, allowing the operating knob to open and rotate. At the same time, the release knob is rotated by a certain angle.

Thereafter, in order to remove the socket, it is only necessary to rotate the release knob to the initial position, which causes the sliding plate to return to the initial position, thereby lifting the frame diagonally and opening the operating cylinder. is pushed in and the socket is removed from the plug.

As described above, in this conventional type, the frame body moves in parallel while keeping its top surface horizontal to push in the actuating cylinder of the socket, so when removing the socket from the plug, there is no excessive force on the socket. There are benefits not to be added.

However, the operating torque required to remove the socket increases and the frame mounting structure becomes complicated.

This is because, in addition to the sliding plate, the frame body slides on the Kotuku body.

The present invention provides a sliding plate 8 that interlocks with the operating means on the side of the socket of the socket main body 1, and connects a pushing means for pushing the operating cylinder 25 of the socket 24 to the tip of the sliding plate 8. However, when the socket 24 of the plug 3 is connected, the sliding plate 8 is advanced by the pushing means, and the lock can be opened, and by returning the sliding plate 8 to the initial position by the operating means. In the device in which the pushing means pushes the operating cylinder 25 of the socket 24, the pushing means is designed to reduce the operating torque when removing the socket and to prevent excessive force from being applied to the socket when removing the socket. The technical problem is to make it possible to push in the approximate center of the operating cylinder of the socket without sliding on the socket body.

The technical means of the present invention taken to solve the above-mentioned technical problems is to form a straight through gas flow path in the body 1 of the cot, and to install a plug at the tip of the straight through gas flow path so as to be coaxial with the through gas flow path. 3 is attached, and a closure 4 is inserted in the middle of this through flow path so as to be perpendicular to it, and the operating means is a Kotoku operating knob 23, which rotates integrally with this and is provided with a protruding piece 7. The sliding plate 8 and the operating knob 23 are interlocked via the rotating plate 5, and the release lever 10 is pivotally supported near the attachment part of the plug 3 at the tip of the main body 1. A release piece 12 is connected to the tip and the other end projects toward the center of the base of the plug 3, and this release piece 12 is formed into a convex arc-shaped portion toward the tip side of the plug 3, and the sliding plate 8 is The sliding plate 8 is constantly biased in the return direction and
A pin 9 is provided on the Kotoku body 1 and protrudes in the opening direction of the protruding piece 7 which is in contact with the lower surface of the protruding piece 7 in the fully closed position.
The protrusion 7 and the sliding plate 8 are made to engage only in a certain range of reverse rotation from the fully closed position.

The above technical means of the present invention operates as follows.

When the socket 24 is connected to the plug 3, the actuating tube 25 protrudes and pushes the release piece 12 in the initial position, which causes the sliding plate 8 to advance a certain distance and the operating knob 23 to fully close. set in position. From now on, operation knob 23
When rotated in the forward direction, the rotating plate 5 and the operating knob 23
rotates independently from the sliding plate 8, and the cock is fully opened.

When removing the socket, the operation knob 23 is first rotated in the opposite direction to the fully closed position, and then further rotated in the opposite direction by a certain angle from this position. As a result, the sliding plate 8
The release piece 12 is lifted by the interlocking relationship between the release lever 10 and the release lever 10.

At this time, the tip of this release piece 12 is connected to the socket 2.
4, the diameter line of the actuating cylinder 25 is pushed in,
No unreasonable force is applied to the operating cylinder 25, and the socket 24 is removed from the plug 3 by this pushing operation.

Further, when the socket 24 is not connected to the plug 3, the pin 9 is in a protruding state, and the pin 9 and the protruding piece 7 are in a protruding state.
Since the operating knob 23 is engaged in the fully closed position, opening rotation is prevented.

Furthermore, if the operation knob 23 is set to a half-open state without the socket 24 connected due to mischief or the like, the protrusion 7 and the pin 9 are in a one-way engagement relationship, so that the socket 24 is not connected. Even without connecting the operating knob 23, that is, the rotating plate 5 can be rotated back and the pot can be closed.

Since the present invention has the above configuration, it has the following characteristic effects.

To remove the socket, use the operation knob 2.
3 and a release lever 10 as a pushing means.
Since the socket is configured to directly interlock with the sliding plate 8, the socket removal mechanism is simplified.

Since the release lever 10 does not slide on the cock body, the operating torque is reduced.

Further, even if the operating knob 23 is set to a half-open state due to mischief or the like, it can be forcibly returned to the half-open state, so it is safer than the conventional system described above.

Fig. 1 shows a plan view of an embodiment of the present invention.
A gas flow path is formed from the to the plug 3,
A rotating plate 5 that rotates together with the plug 4 inserted into the gas flow path is attached to the shaft portion 6 of the plug, and the projecting piece 7 is
A sliding plate 8 slidably arranged on the side of the Kotoku main body 1
corresponds to As shown in FIG. 2, this sliding plate corresponds to a pin 9 and a release lever 10 that are embedded in the Kotuku body 1 so as to be able to rise and fall freely. The piece 12 is located near the base end of the plug 3, and the other base 13 passes through a through hole 14 at the tip of the sliding plate 8, so that the sliding plate 8 and the release lever 10 are positively interlocked.

The upper part of the pin 9 is cut into a semicircular shape, and the stepped part 15 abuts the lower edge of the sliding plate 8.
The flat part with a semicircular cross section is in contact with the sliding plate 8, and its top protrudes from the main body 1 and faces the vicinity of the rotating plate 5. Furthermore, the pin is pushed by a spring 16 disposed below the pin. It has a protrusion force of 9. In addition, a protrusion 17 is formed at the base end of the sliding plate 8, and a tension spring is inserted between a pin 18 implanted here and a pin 19 disposed on one side of the upper part of the kettle body 1. 20 is interposed to apply a return force to the sliding plate 8. Further, an inclined portion 21 is provided at an appropriate position on the lower edge of the sliding plate 8 where the stepped portion 15 of the pin 9 comes into contact.
is provided, which corresponds to the step 15 of the pin 9 in the socketed state.

Next, a suitable range of the rear surface of the projecting piece 7 of the rotary plate 5 is made into an inclined surface 22, and this inclined surface is opened toward the closed rotation side.

To explain the operation of the above-mentioned embodiment in more detail, in the state shown in the figure, the stopper 4 is in a fully closed state, and the pin 9 embedded in the pot body 1 protrudes near the protrusion 7 of the rotating plate 5 and rotates. Opening movement of the moving plate, that is, the operating knob 23 is prevented.

When the socket 24 is attached to the plug 3 in this state, the actuating cylinder 25 of the socket 24 advances to maintain the connection between the two, but at this time, the actuating cylinder 25 pushes the release piece 12 of the release lever 10. When pushed in, the release lever swings about the fulcrum 11. As a result, the sliding plate 8 moves forward against the spring 20, and the inclined part 21 of the lower edge contacts the stepped part 15 of the pin 9 and moves forward further to push the pin, and the upper end of the sliding plate 8 moves forward against the rotating plate 5. It will be in a state located lower than the protruding piece 7.

This makes it possible to rotate the rotary plate 5 to open, that is, to open the stopper 4. Further, at this time, the protruding portion 17 of the sliding plate 8 is in a state of protruding into the vicinity of the protruding piece 7 of the rotating plate 5. (FIG. 3) When the operation knob 23 is rotated to open from the above state, the plug 4 is opened and gas is supplied to the plug 3 and below.

Next, when the operation knob 23 is rotated back, the stopper 4 is fully closed, and when the operation knob 23 is rotated further in the return direction from this fully closed position, the protrusion 7 comes into contact with the protrusion 17, causing the sliding plate 8 to retreat. , the release lever 10 that is interlocked with this swings, and the release piece 12 engages the socket 2.
4, and the socket is removed from the plug 3.

With this, the sliding plate 8 also returns to its initial state, and the pin 9
The stepped portion 15 is also located away from the inclined portion 21 toward the tip side, and due to the biasing force of the spring 16, it protrudes near the opening rotation side of the protruding piece 7 and returns to the initial state.

Apart from the above operation, if the stopper 4 is left half open without the socket installed due to an incorrect operation,
The protruding piece 7 is positioned with the pin 9, resulting in the state shown in FIGS. 4 and 5. When the stopper 4 is rotated to close from this state, the lower surface of the protruding piece 7 of the rotating plate 5 forms an inclined surface. 22, this allows the top of the pin 9 to be pushed in and rotated to return to the fully closed state, and there is no need to worry about leaving it in a dangerous half-open state.

Although the shaft portion 6 rotates integrally with the plug 4, they are separated and engaged by appropriate means, and the force applied to the rotating plate 5 does not directly act on the plug 4. does not adversely affect flow path blocking performance.
