Description

  TECHNICAL FIELD The present invention relates to a water meter holder base that removably supports both ends of a water meter and connects to a pipe part, and a pipe joint set at an end part of the holder base is not fixed by screwing or the like but is inserted and fitted. The present invention relates to a fitting insertion meter holder base that can efficiently perform water pipe work.

Conventionally, the connection between the water pipe section and the holder base body that supports the water meter is performed by attaching a water meter attachment / detachment device to a water supply device such as a valve as described in Patent Document 1, for example. A fixed connecting means has been taken such as connecting by a connecting mechanism such as a nut or overlapping a flange body formed at a connection end as in Patent Document 2 and fastening with a bolt and a nut.
Japanese Patent No. 3658456 Japanese Patent No. 3042975

  However, screwing and fastening of cap nuts, etc., and bolts and nuts with flanges in water supply equipment require a lot of time and effort to rotate the screwed body, and are expected to be connected from the beginning. Because it can only be applied to water supply equipment, it was not possible to increase the width of piping design.

  In addition, since tap water flowing from the water supply pipe to the water supply equipment passes through the slider that advances and retreats to pinch the water supply equipment, tap water and dust enter the structural part of the advance / retreat mechanism and cause failure. There was a problem that it was easy.

  Furthermore, since the joint portion is fixed in a direction, it is not possible to perform free piping at the setting site of the water meter, and there is a problem that extra piping members and setting space must be used.

  In view of the above-described problems, the present invention intends to cope with this, and in order to clamp and support the water meter on the base body, the slider back portion of the tightening holder that moves forward and backward with respect to the receiving holder is attached to the tip of the pipe joint. In addition to the insertion structure to be inserted, a pipe joint fitting structure is formed on the back of the holder body to which the slider is fitted.

  By inserting the end of the pipe joint into the insertion structure of the rear part of the slider as described above, the end of the pipe joint inserted is covered with the structure of the slider advancing / retreating mechanism, so that tap water or dust Can be prevented, and the insertion distance can be increased to stabilize the fitting of the pipe joint.

In addition, the pipe fitting fitting structure is configured such that the fitting body is pivotably fitted, and the elbow-like joint is pivotally fitted to the end of the meter holder base, thereby enabling the water meter setting unit The piping can be set in any direction by turning the elbow, and the installation angle of the water supply equipment to be joined to the joint can be set freely.

  Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a base body, which is provided with a pair of holders 2a and 2b that are opposed to both side ends. One is a clamping holder and the other is a receiving holder that is crimped to both ends of the water meter A to bring the meter A to the middle axis level of the base body 1 The end portions on both sides of the main body 1 serve as attachment portions 12 to the floor surface or the like.

  In the tightening holder 2a, the handle body 3 is screwed to the holder outer body 2 fixed to the base body 1, and the slider 4 supporting the end of the water meter A is screwed to the handle body 3 so that the handle body 3 is rotated. The slider 4 is moved forward by a moving operation and the end of the water meter A is pressed against the holder 2b, the water meter A is held between the holders 2a and 2b, or the slider 4 is moved backward to retreat the water meter A. And the meter A is removed.

  The handle body 3 is provided with a male screw 31 which is engaged with a female screw 21 engraved on the inner periphery of the holder outer body 2 on the outer periphery, and a male screw 41 which is engraved on the outer periphery of the slider 4 on the inner periphery. A female screw 32 to be screwed is engraved, and the outer peripheral screw and the inner peripheral screw are opposite to each other, and the other screw is rotated by the rotation operation of the handle body 3. It is configured not to receive.

  The pitch of the female screw 32 that engages with the male screw 41 of the slider 4 of the handle body 3 is set to be about twice as large as the pitch of the male screw 31 that engages with the holder outer body 2, and when the handle body 3 rotates once. The slider 4 is configured to advance and retract with an advance / retreat width twice that of the handle body 3. The slider advancing / retreating mechanism is an example of the advancing / retreating mechanism, and other configurations may be used as long as the slider is configured to advance / retreat by the rotation of the handle body.

  The slider 4 has a male screw 41 on the outer periphery and a fitting frame 42 that is joined and fitted to the end channel of the water meter A on the tip side, and a tip fitting portion 51 of the pipe joint 5 on the rear end side. In addition to the fitting structure portion 43 to be fitted, a pipe joint fitting mechanism 22 is provided on the back of the holder outer body 2 to which the slider 4 is fitted, and the fitting structure portion 52 of the pipe joint 5 is fitted.

The leakage of fluid flowing from the flow path of the joint 5 to the flow path of the water meter A via the slider 4 is prevented. The O-ring 44 can be easily replaced by removing the slider 4 by adjusting the length of the locking body 11 set on the base body 1 and the tip distance of the slider 4 so that the slider 4 can be removed. It becomes possible.

  The rotation mechanism of the pipe joint fitting mechanism 22 of the holder outer body 2 and the pipe joint fitting structure 52 is formed of elastic resin stoppers on the outer periphery of the fitting structure 52 and the inner circumference of the joint fitting mechanism 22, respectively. Insertion grooves 24 and 54 into which the ring 53 is fitted are provided. When the retaining ring 53 is fitted into the outer circumferential fitting groove 54 of the fitting structure portion 52 and forcibly press-fitted into the joint fitting mechanism 22, the compressed retaining ring at the time of insertion is compressed. 53 is restored in the fitting groove 24 on the inner circumference of the joint fitting mechanism 22 and is fitted into the fitting groove 24 on the inner circumference of the joint fitting mechanism 22 so that the fitting groove 24 of the holder outer body 2 and the fitting groove 54 of the pipe joint 5 are formed. In addition to being connected, the inner wall of the synthetic groove formed by the both insertion grooves and the surface of the retaining ring 53 are configured to slide and rotate.

  If the pipe joint 5 is constructed in an elbow type joint structure as shown in FIGS. 3 and 4, the fitting structure part 52 is connected to the holder part 2 via the rotating mechanism, so that the elbow can be moved at an arbitrary angle.
