Description

[Detailed Description of the Invention] The present invention includes a half-saddle member that holds a branch stopper for a conduit, and another half-saddle member that is paired with the half-saddle member that holds the conduit, one of the half-saddle members. A shaft member having an axis along the axis of the conduit is provided at one end, and a bearing portion into which the shaft member is fitted is formed at one end of the other half saddle member. the shaft members are pivotally connected to each other so as to be swingable about the axis of the shaft member, and
The present invention relates to a branched plug saddle that is provided with a tightening connector that tightens the free ends of these half-saddle members on opposite sides of the axis in a direction that draws them toward each other.

This type of branch plug saddle allows both half-split saddle members to swing open and close around their pivot points, making it easy to fit and secure the mantle to the conduit, and to improve the efficiency of branching work. If the split saddle member is of a type that cannot be divided, it becomes bulky during the distribution stage, making it difficult to carry a large number of branch plug saddles.

Therefore, in the past, as shown in Japanese Utility Model Publication No. 52-7860, for example, the pivot portions of the two half-saddle members were configured in a hinge type, and the free end side was connected using bolts and nuts. Configuring techniques have also been proposed. With this configuration, the two halves of the saddle members can be separated and connected at the pivot point, so that they can be separated and stacked on top of each other during the distribution stage, thereby making it more compact and increasing the volumetric efficiency. However, in this conventional technology, both halves of the saddle members are configured so that they can be separated and connected from any relative position, so even in the closed position where they are wound around the conduit, if the tightening connection point loosens, the halves can be separated and connected. There was a problem in that the split saddle member was easily separated at the pivot connection point, and restoration work was time-consuming.

Although the present invention is a swing opening/closing type and allows the two halves of the saddle members to be compactly stacked on top of each other during the distribution stage, the structure for this purpose does not require the work of fitting the saddle into the conduit and the work of fitting it into the conduit and connecting it to the conduit. It is an object of the present invention to provide a branch plug saddle that does not impede the stability of a connected posture and can promote improvement in workability.

The characteristic configuration of the present invention for achieving the above object is that, in the above-mentioned branch plug saddle, the shaft member formed in the one half-saddle member is moved in the radial direction of the conduit held by both half-saddle members. The bearing portion of the other half saddle member has a diameter smaller than the long axis of the shaft member and smaller than the short axis of the shaft member. A notch with a larger width is formed along the circumferential direction of the conduit on the outer peripheral side of the other half-saddle member, and is opened in a direction toward the end opposite to the side where the bearing portion is present. This structure has the following advantages.

In other words, when the double-half saddle member is in a tightening state during use or simply hanging in the hand,
If the two halves of the saddle members do not separate from each other and do not intentionally swing open beyond the open rocking position in which they can be inserted into and removed from the conduit from the closed position, the two halves of the saddle members will separate and connect. Since this is not possible, there is little risk that the two halves of the saddle members will come off unexpectedly not only in the fixed position of fitting the mantle into the conduit, but also when swinging to close to that position or swinging open from that position. In other words, after the two halves of the saddle members are pivotally connected, they will not come off unexpectedly, even if you handle them roughly, such as by throwing them.
There is no accidental dislodgement during fitting the mantle into the conduit.

Hereinafter, embodiments of the present invention will be described based on the drawings.

The branch plug saddle connects the branch plug 20 to the conduit 21.
The shaft members 5, 5' connected to the upper half-saddle member 1 that holds the are fitted into the corresponding bearings 6, 6' connected to the lower half-saddle member 2, and the shaft of the conduit 21 is inserted. It is pivotally connected to swing open and close around an axis P parallel to the core, and 3 and 3' are swing fulcrum parts of both half-saddle members 1 and 2, 4 is a tightening connector, Specifically, the fulcrum parts 3 and 3' are provided at both ends in the width direction along the axis P, and the connector 4 is provided in the middle part in the width direction. Both fulcrum portions 3, 3' include shaft members 5, 5' integrally connected outward in the width direction at the end of the upper half-saddle member 1, and shaft members 5, 5' at the end of the lower half-saddle member 2. Shaft members 5, 5'
A bearing part 6 integrally connected to surround the interior of the bearing part 6,
6', the connecting tool 4 is connected to bolt holes 7 and 8 formed in the free end flanges of both half saddle members 1 and 2, and between both holes 7 and 8. A case is shown in which a bolt/nut 9 is inserted and tightened. In this case, the shaft members 5, 5' are formed by cutting a part of the cylinder into a substantially flat shape so that the cross-sectional shape has different diameters including a major diameter portion and a minor diameter portion, while the bearing portions 6, 6' are notches 6a and 6 for inserting and removing the shaft members 5 and 5'.
a', and at a certain opening angle (b) in Fig. 4 when the two half-saddle members 1, 2 are swung sufficiently wide from the predetermined closed state (a) in Fig. 4, the shaft members 5, 5' The shaft members 5, 5' can be pulled out from the bearing parts 6, 6' and reinserted in a state where the flat parts are in contact with the outer peripheral surface of the lower half-saddle member 2. In terms of angle, the opening widths of the notches 6a, 6a' are determined in relation to the diameters of the shaft members 5, 5' so that they cannot be inserted or removed. In other words, the two half saddle members 1,
The shaft members 5, 5' formed on one of the half saddle members 1 of 2 are arranged such that the direction along the radial direction of the conduit held by both half saddle members 1 and 2 is the major axis, and the direction along the circumferential direction The bearing portion 6 of the other half saddle member 2 is configured to have different diameters with the minor axis in the direction, and the bearing portion 6 of the other half saddle member 2,
6' are provided with notches 6a, 6a' having a width smaller than the major axis of the shaft members 5, 5' and larger than the minor axis thereof, in the circumferential direction of the conduit on the outer peripheral side of the other half saddle member 2. It is formed to be open in the direction along the same direction and toward the end opposite to the side where the bearing parts 6, 6' are present.

In addition, the bearing part 6,
6' may be implemented by providing shaft members 5, 5' on the lower half-saddle member 2.

In the figure, reference numeral 10 denotes a female threaded cylindrical portion formed in the circumferential middle of the upper half saddle member 1, into which a branch plug 20 is screwed. Reference numeral 11 denotes an annular packing fitted to the circumferential portion of the cylindrical portion 10, and is pressed against the outer circumferential surface of the conduit 21. 12 is a valve body, 13 is a valve body holder, 14, 15

Reference numeral 18 indicates a blind packing, and reference numeral 19 indicates an anti-corrosion core for the peripheral surface of the branch opening formed in the conduit 21.

When the upper and lower halves of the saddle members 1 and 2 are superimposed in the same direction, one of the halves of the saddle halves 1 and 2 shown in FIG. Next, the shaft member 5' can be inserted into the bearing portion 6, and the bolts and nuts 9 can be inserted into both holes 7 and 8.
