Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is particularly suitable when replacing a water pipe water pipe, in which the packing provided at the connection between the water pipe and the upstream water pipe can be reliably and easily replaced. Regarding tools.

[0002]

[Prior art]

 Normally, the water meter installed in the water pipe is replaced every 10 years. When replacing the water meter, remove the nut that is screwed near the water stopcock and separate the upstream water pipe and the water meter for replacement work.

When connecting a new water meter, a packing is interposed at the connecting portion between the upstream side water pipe and the water meter to prevent water leakage. In order to install the packing, the upstream water pipe and the water meter must be opened to a thickness that allows the packing to be installed. However, since the upstream water pipe and the water meter are always connected by being crimped inward, they must be pulled outward by a strong force.

Therefore, conventionally, when installing the packing, a tool such as a screwdriver or pliers was used to pull the upstream side water pipe and the water meter outwardly to secure a space and install the packing. .

[0005]

[Problems to be solved by the present invention]

 However, the series of work to install the packing while pulling the upstream water pipe and the water meter outwardly was extremely difficult and dangerous work by one person. In addition, since the water pipes are installed at a lower position than the ground, it was necessary to work in a cramped position when using tools such as drivers and pliers.

In view of the above points, the present invention has an object to provide a water pipe attachment / detachment tool that allows a packing interposed between a water meter and an upstream water pipe to be installed in a comfortable posture and easily. To do.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, a water pipe attaching / detaching tool of the present invention comprises a stay having a handle at one end and a locking portion at the other end, and a handle at one end and a locking portion and a latch plate at the other end The stem was pivotally connected by a pivot, and an arm with a spring and a butterfly screw were provided in the middle of the handle and pivot. Further, an elastic material is installed on the lower surface of the latch board.

[0008]

[Action]

 Hereinafter, the operation of the present invention will be described with reference to the drawings. (1) Loosen the nut 36 screwed near the water stopcock 35. (2) The locking portion 6 provided on the lower part of the main body 1 is connected to the pipe 41 of the upstream water pipe 40, the locking portion 7 is attached to the side surface of the water meter 30, and the latch plate 8 is attached to the lid 31 of the water meter 30. Hang on. (3) Grip the grips 2 and 3 inward. (4) When the water meter 30 and the upstream side water pipe 40 are separated, the butterfly screw 11 screwed on the arm 10 is adjusted to fix the stay 4 and the stay 5. (5) Insert the packing 50 between the water meter 30 and the upstream water pipe 40. (6) Turn the butterfly screw 11 and remove the main body 1. (7) The nut 36 is screwed on.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

The main body 1 includes a handle 2, a handle 3, a stay 4, a stay 5, a locking portion 6, a locking portion 7, a latch 8, a spring 9, an arm 10, a butterfly screw 11, and a pivot 12. .

The stay 4 has a flat plate shape and a substantially central portion is curved, and a grip 2 to which a grip portion 13 made of synthetic resin or a hard member is fixed is provided on the upper side of one end. An inverted U-shaped locking portion 6 is fixed to the end.

The stay 5 has a flat plate shape and a substantially central portion is curved, and a grip 3 to which a grip portion 14 made of a synthetic resin or a hard member is fixed is provided on one upper side of the stay 5. An inverted U-shaped locking portion 7 having a substantially central curved portion is fixed to the other end, and side surfaces of the water meter 30 are locked to both arm portions 15 below the locking portion 7. The engaging convex portion 16 is installed, and the shallow groove 22 is formed in the contact portion with the water meter 30. In addition, a disk-shaped locking plate 8 for locking the lid 31 of the water meter 30 is fixed to the outside of the locking portion 7.

An elastic material 17 made of urethane resin or the like is preferably installed on the lower surface of the latch plate 8 so that the latch plate 8 is softly pressed by the lid 31 of the water meter 30.

The substantially central curved portions of the stays 4 and 5 are rotatably connected by a pivot 12 and a nut 18.

An elongated arm 10 with a spring 9 interposed is installed at a substantially intermediate portion between the grips 13 and 14 and the pivot 12. The arm 10 is rotatably loosely attached to the holders 19 and 20, one end is fixed by a fixing nut 21, and the other end is screwed by a butterfly screw 11. Further, by adjusting the thumbscrew 11, it is possible to regulate the outward opening of the handles 2 and 3.

Next, an example of use of the water pipe attachment / detachment tool of the present invention will be described with reference to FIGS. 4 and 5.

First, the nut 36 screwed near the water stopcock 35 is loosened. Next, the inverted U-shaped portion of the locking portion 6 of the main body 1 is inserted into the pipe 41 of the upstream water pipe 40. Further, the locking portion 7 has an inverted U-shaped portion joined to the side surface of the water meter 30 and the latch plate 8 joined to the lid 31 of the water meter 30. Although the convex portion 37 is installed on the side surface of the normal water meter 30, the locking portion 7 has a substantially central portion that is curved outward, and the locking convex portion of both arms 15 of the inverted U-shaped portion. Since the lower portion of the water meter 30 is locked by the portion 16, the convex portion 37 does not contact the locking portion 7.

After mounting the main body 1, the grips 2 and 3 are gripped inward. Then, the engaging portion 6 engages with the pipe member 42 of the upstream water pipe 40, and the engaging portion 7 opens outward while engaging with the side surface of the lower portion of the water meter 30. When the upstream water pipe 40 and the water meter 30 are separated, the butterfly screw 11 screwed onto the arm 10 is rotated to prevent the locking portions 6 and 7 from returning.

After replacing the water meter 30 and inserting the packing 50 between the upstream side water pipe 40 and the water meter 30, the butterfly screw 11 is reversed, the main body 1 is removed, and the nut 36 is screwed on. .

[0020]

[Effect of device]

 As described above, the water pipe attaching / detaching tool of the present invention has the following effects by having the above configuration. (1) Since a handle having an appropriate length is provided, it is possible to work in a comfortable posture. (2) Since the upstream water pipe and the water meter can be fixed by adjusting the thumbscrew of the arm, the packing can be easily replaced by one person. (3) Since the locking board is provided with the elastic material, the water meter is not damaged.
