When installing or removing the connection screw, the connection screw is tightened or loosened using an appropriate jig such as a spanner. This configuration solves the problem that it is inconvenient to use the jig in a narrow meter box and the workability is poor. Particularly in cold regions, water pipes are buried deep underground to prevent freezing, and accordingly, meter boxes are also installed relatively deep. Therefore, if the meter box is narrow and installed at a deep position, it becomes even more difficult to replace the meter using a jig such as a spanner.

る。Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a meter box, and a meter 2 is disposed within the meter box. To install this meter 2, a holder member 3 is provided in the meter box 1, and holding parts 4 and 5 rising upward are provided on both sides of the holder member. The joint body 6 is held, and the other holding part 5 holds a water stopcock 7. And the meter 2 is the joint body 6
The water stop valve 7 is connected to the water stop valve 7 by being pressed and held between the water stop valve 7 and the water stop valve 7. As shown in FIGS. 2 to 4, the joint body 6 is divided into a valve chamber 12 and an operation chamber 13 by providing a ring-shaped partition 11 approximately at the center inside a cylindrical body 10. Then, the socket pipe 15 is attached to the valve chamber 12 side so as to press the ring-shaped stopper member 14. A sliding pipe 16 is disposed in the operation chamber 13, and a tubular stopcock member 17 is integrally attached to one end of the sliding pipe by screw means or the like, and an inner wall is attached to the other end of the sliding pipe. A protruding flange portion IE3a is provided, and a meter connecting member 18 is disposed along the inside of the flange portion so as to be freely protrusive and retractable, and the meter connecting member is always urged in the protruding direction by a coil spring 19. The sliding tube 16 is driven by a plug rod 20 that is disposed through the body 10. That is, the body 10 has a through hole 2.
1 is formed, and a rising portion 22 is formed along the peripheral edge of the through hole.
A stopper rod 20 is attached via a fixing member 23 that is screwed inside the rising portion 22, and an eccentric shaft 20a is formed at the lower end of the stopper rod. The eccentric portion is engaged with the recess 24 of the sliding tube 16. As shown in FIG. 3, the water stop valve member 17 is configured such that a cylindrical portion 25 and a water passage portion 26 formed of plates disposed in a cross shape are loosely fitted together, and the cylindrical portion has the sliding portion. A flange-like threaded portion 27 is formed for coupling with the pipe 16, and a disk-shaped partition wall 28 is integrally formed approximately in the middle of the water passage portion 26, and along the top of the partition wall. A packing 29 is provided. A convex portion 30 for a stopper is formed at the free end of the water passage portion 26, and the convex portion 30 engages with the stopper member 14 and is arranged so as not to be washed away by the water flow. . The meter connecting member 18 is provided with a flange portion 31 on its base side, and a flange member 32 is attached on its protruding end side. As shown in FIG. 4, this flange member 32 has a stepped portion 33 into which the end of the meter 2 fits, and a pair of receiving members on both sides of the lower half circumference along the stepped portion. 34 are formed protrudingly facing each other, and a pair of protrusions 35 for preventing rotation are formed protrudingly from the lower part. Then, the end of the meter 2 is placed on the receiving member 32, positioned, and connected in a press-contact state.
The boat fishing meter 2 has a screw carved into the outer peripheral surface of its end, and since the end is thin, a nut-shaped adapter 36 is used. This adapter 36 does not need to be used if the end of the meter 2 can be formed relatively thick. When using the adapter 36, it is screwed onto the end of the meter 2 with a gasket 37 interposed therebetween, and an O-ring 38 is attached to the end surface that abuts the flange member 32. Note that the flange member 32 is connected to the meter connecting member 18.
After being attached to the flange member, the bottle member 39 is positioned between the protrusions 35 so that the flange member does not rotate. The other end of the meter 2, that is, the end connected to the water stop valve 7 side, is configured to have an adapter 41 with a check valve 40 attached thereto, and to be connected to the water stop valve 7 by pressure contact. ing.

になるのである。The water meter connection structure of the present invention having the above configuration allows the meter 2 to be easily replaced, for example, even if the meter box 1 is installed at a deep position. That is, in the installation state shown in FIG. 1, first, the stop valve 7 is closed using, for example, a valve opener. Next, the stopper is engaged with the stopper rod 20 of the joint body 6, and the stopper is approximately 9o''
When it is rotated, as shown in FIG. 5, the sliding tube 16 that is engaged with the eccentric shaft 20a moves to the left in the figure. Then, the cylindrical portion 25 of the water stop valve member 17 attached to this sliding pipe 16 also moves to the left,
Its end portion abuts against the gasket 29 of the partition wall 28. In this abutting state, the partition wall 28 is under pressure due to water pressure, so it acts in the direction of self-closing at the abutting position, blocking the water passage 26 and bringing the inside of the joint body θ into a water-stop state. . Even in this water stop state, it has not completely rotated 90@, so when it is rotated further, the sliding tube 16 moves further to the left, and its flange portion 16a engages with the flange portion 31 of the meter connecting member 18. Then, the meter connecting member 18 is slightly moved to the left against the fill spring 19. As a result of this movement, the pressurized state between the flange member 32 and the adapter 36 is released and the meter 2 is placed on the receiving member 34, so that the meter 2 is simply pulled upward. It can be removed. Even when installing or replacing a new meter, attach or replace the adapter 36 at both ends of the meter 2, and
Replace the ring 38 with a new one, align and place it on the receiving member 34 of the flange member 32 in the same manner as above,
By rotating the stopper rod 20 by 90@ with a stopper, the sliding pipe 16 moves to the right, the end of the cylindrical part 25 separates from the seal 29, and the water passage part 26 becomes water-flowing state, and the meter The spring pressure of the coil spring 19 that presses the connecting member 18 becomes stronger, and the contact pressure between the flange member 32 and the adapter 36 also becomes stronger, making it possible to establish a stable connection. Then, when the stop valve 7 is opened, water is allowed to flow.

ちに使用できると言う優れた効果を奏する。As explained above, the water meter mounting structure according to the present invention has a joint body connected to one end of the meter,
A stop valve is connected to the other end, and the connection structure is such that these are arranged in a meter box, and a sliding pipe that is slid by a stopper rod that can be operated from the outside is provided in the joint body, and the stop valve is connected to the other end. A water stop valve member and a meter connecting member are provided on the sliding pipe,
The water stop valve member is composed of a water passage portion in which plate cane members are arranged in a cross shape along the length direction, and a partition wall in which a gasket is arranged, and the meter connecting member is spring-biased in the projecting direction. At the same time, a flange member is attached to the protruding end side,
A receiving member on which the end of the meter is placed protrudes from the flange member, and with the end of the meter placed on the receiving member, the end of the meter is pressed and connected by a spring bias, and the stopper rod is rotated and slid. The structure is simpler than that of the prior invention because the tube can be moved forward and backward to perform pressure contact and separation, but the mechanical structure allows for reliable and easy meter installation and removal. It has excellent effects. Further, when the sliding pipe moves forward by rotating the stopper rod, the pressure contact is maintained, and when the sliding pipe moves backward, the water stop state is maintained, and the spring bias of the flange member is weakened. It also has the excellent effect of being able to perform meter replacement work while maintaining a water-stop state. Furthermore, by attaching an adapter to the end of the meter, an excellent effect is achieved in that even a conventionally used general meter can be used immediately.
