Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desorption jig for a coupler connected to a hose of a tank truck at a gas station, for example.

[0002]

2. Description of the Related Art For example, at a gas station, a coupler connected to a hose of a tank truck comprises a male pipe member and a female pipe member which can be fitted. Normally, the male pipe member is fixedly installed at the gas station, the female pipe member is connected to the hose of the tank truck, and the female pipe member is fitted to the male pipe member to supply the fuel to the tank of the gas station. .

For example, FIGS. 4 and 5 are views showing a coupler comprising a male pipe member 10 and a female pipe member 12. A sleeve 14 and an outer flange 16 are provided on the outer circumference of the tip of the female pipe member 12 of such a coupler. A lock (lock ball) is provided below the sleeve 14 of the female pipe member 12.
18 are arranged. This lock 18 is a male pipe member 10.
The engaging groove 20 is engaged. Further, the spring 22 biases the sleeve 14. A seal member 24 is provided inside the male pipe member 10, and the seal member 24 cooperates with a seal member 24 a inside the male pipe member 10. A seal member 26 is provided inside the female pipe member 12, and the seal member 26 cooperates with a seal member 26 a inside the female pipe member 12.

When removing the coupler, the sleeve 14 is pushed toward the outer flange 16. As shown in FIG. 5, when the sleeve 14 is pushed in, the lock 18 is released from the sleeve 14, and the female pipe member 12 can be removed from the male pipe member 10. When inserting the female pipe member 12 into the male pipe member 10, the female pipe member 12 is inserted into the male pipe member 10 in a state where the sleeve 14 is pushed toward the outer flange 16 as in the previous case. When the attachment / detachment is completed in this way, when the sleeve 14 is released from the hand, the sleeve 14 is returned to the original locked position by the force of the spring 22.

[0005]

When attaching and detaching the coupler, it was necessary for the operator to grasp the female pipe member 12 with one hand and the sleeve 14 with the other hand. Then, while pulling the sleeve 14 toward the operator, it is necessary to push out the female pipe member 12 in front of the operator or pull the female tube member 12 toward the operator. However, it is surprisingly difficult to attach and detach the coupler accompanied by such an operation, and the work is performed in a posture where it is difficult to perform the work, and conventionally, it was necessary to swallow the so-called knack. In addition, the larger the coupler, the larger the diameter of the female tube member and sleeve, making it difficult to grip.
The weight also increases. For example, a large coupler has an outer diameter of 1
It is 10mm long and 130mm long. In addition, the spring force of the spring that returns the sleeve to the original position also increases. For this reason, it is very difficult for the coupler to be attached and detached by one person, and it is necessary for two persons to perform the operation. In addition, the coupler is installed and removed in a clean booth to maintain a clean atmosphere, but since the clean booth is small,
It was difficult for them to work together.

An object of the present invention is to provide a coupler attaching / detaching jig capable of easily attaching / detaching a large coupler.

[0007]

A coupler attaching / detaching jig according to the present invention comprises a male pipe member and a female pipe member which can be fitted,
One of the pipe members has an outer flange, a first portion located on the tip side of the outer flange, a second portion located on the opposite side of the first portion from the outer flange, and the first portion. And a sleeve slidably fitted to the portion, and a detachment for a coupler that allows the male and female pipe members to be detached by bringing the sleeve closer to the outer flange. A jig, which is engageable with the sleeve and has a gripping portion for grasping by hand, and an engageable outer flange from the second portion of the one pipe member And a second jig member having a gripping portion for grasping with a hand.

The first jig member may be C-shaped so as to partially enclose the sleeve, and may be provided with an inward projection engageable with the end surface of the sleeve. . Further, the second portion of the one pipe member is formed in a taper shape whose diameter increases toward the outer flange, and the second jig member is a portion where the diameter of the taper-shaped second portion is small. It is also possible to have a C-shaped configuration that passes through but does not pass through a portion having a large diameter.

[0009]

In the above structure, the first jig member and the second jig member are engaged with the sleeve, and the second jig member is engaged with the outer flange of the one pipe member. When the grip portion of the second jig member is grasped at the same time, the sleeve moves toward the outer flange and the lock is released. Therefore, if the one pipe member (for example, the female pipe member) is pushed toward the other pipe member (for example, the male pipe member) while the grip portions of the first jig member and the second jig member are held, The connection can be made, and the coupler can be removed by pulling out one pipe member from the other pipe member.

[0010]

EXAMPLES Examples of the present invention will be described below. Figure 1
FIG. 6 shows a female tube member 12 of a coupler similar to the coupler shown in FIGS. 4 and 5. That is, the female pipe member 12 of FIG. 1 can be fitted with the male pipe member 10 shown in FIGS. 4 and 5, and the coupler is constituted by such a male pipe member 10 and a female pipe member 12. The male pipe member 10 is fixedly installed at, for example, a gas station, the female pipe member 12 is connected to a hose of a tank truck, and the female pipe member 12 is fitted into the male pipe member 10 to thereby fill the tank of the gas station with fuel. To supply.

In FIG. 1, a sleeve 14 and an outer flange 16 are provided on the outer periphery of the tip of the female pipe member 12. The sleeve 14 is on the tip side of the outer flange 16, and a portion of the outer flange 16 opposite to the sleeve 14 is a tapered portion 30 whose diameter increases toward the outer flange 16. The sleeve 14 is slidable along the outer circumference of the female pipe member 12 between a position where it engages with the retainer ring 17 and a position where it engages with the outer flange 16 as shown. A lock (lock ball) 18 is arranged below the sleeve 14 of the female pipe member 12. The lock 18 is pushed by the lower wall portion 32 of the sleeve 14 and engages with the locking groove 20 (FIG. 4) of the male pipe member 10 when the sleeve 14 is in the initial position shown. Further, the spring 22 biases the sleeve 14 to the illustrated initial position. A seal member and the like inside the female pipe member 12 are omitted in FIG.

The coupler attaching / detaching jig according to the present invention comprises a first jig member 40 engageable with the sleeve 14 and a second jig member 42 engageable with the outer flange 16 from the tapered portion 30 side. . 2A and 2B are diagrams showing the first jig member 40. FIG. 2A is a plan view of the first jig member 40, and FIG. 2B is a sectional view taken along line II-II of FIG.

As shown in FIGS. 1 and 2, the first jig member 40 has an arcuate C-shape that partially encloses the sleeve 14. The inner diameter of the first jig member 40 is slightly larger than the outer diameter of the sleeve 14, and
0 encloses the angular range sleeve 14 of approximately 200 degrees. The width of the first jig member 40 is slightly larger than the width of the sleeve 14, and includes an inward projection 44 that can be engaged with the end surface of the sleeve 14. In the exemplary embodiment, the inward projections 44 are on both sides. Further, the first jig member 40 has a grip portion 46 for grasping by hand. The grip 46 is a rod-shaped member and is provided on both sides so as to extend on the diameter of the sleeve 14.
Therefore, the first jig member 40 can be engaged with the sleeve 14 only by covering it from the sleeve 14.

3A and 3B are views showing the second jig member 42. FIG. 3A is a plan view of the second jig member 42, and FIG. 3B is a side view seen from the arrow III in FIG. . 1 and 2
As shown in FIG.
It has a C-shape that passes through a small diameter portion of 0 but does not pass through a large diameter portion. That is, C of the second jig member 42
The spacing between the ends 47, 48 of the shape is larger than the smaller diameter portion of the tapered portion 30 away from the outer flange 16 but smaller than the larger diameter portion near the outer flange 16. Therefore, the second jig member 42 is passed through the tapered portion 30 at a portion where the diameter of the tapered portion 30 is small, and then the second jig member 42 is displaced along the tapered portion 30 to remove the second jig member 42 from the outside. One side flange 16
Engage with. As a result, the second jig member 42 does not come off from the female tube member 12, and thus the second jig member 4
The female pipe member 12 can be supported by 2. Further, the second jig member 42 has a grip portion 50 for grasping by hand. The grip 50 is a rod-shaped member, and is provided on both sides so as to extend on the diameter of the outer flange 16.

In attaching and detaching the coupler, the first jig member 4
0 into engagement with sleeve 14 as described above,
With the jig member 42 engaged with the outer flange 16 of the female pipe member 12, the first jig member 40 and the second jig member 42
Simultaneous gripping of the squeeze portions 46, 50 causes the sleeve 14 to move toward the outer flange 16 and unlock. Therefore, if the female pipe member 12 connected to the hose is pushed toward the fixed male pipe member 10 while holding the grip portions 46 and 50 of the first jig member 40 and the second jig member 42, the coupler is connected. When the female pipe member 12 is pulled out from the male pipe member 10, the coupler can be removed. Conventionally, the left hand and the right hand had to be moved separately, which was troublesome, but the first and second jig members 40 and 42 have the squeeze portions 46 and 50 respectively on both sides in a diametrical manner. Therefore, the coupler can be attached and detached by moving the female pipe member 12 in the same direction with both hands while grasping the grip portions 46 and 50 with both hands and maintaining the unlocked state. Moreover, the grip portions 46 and 50 are easier to grip than the female pipe member 12 and the sleeve 14 having a large diameter.
