Description

  The present invention relates generally to an exchanger used when replacing a water faucet with a saddle that branches a water supply pipe from a water main, and more specifically to an attachment structure used for such an exchanger.

  Conventionally, a water faucet with a saddle has been widely used as a method of diverting water without being cut off from a water main buried in the ground.

Among the conventional water faucets with saddles, there is a water faucet body provided with a ball type valve body (also called a ball type). When replacing the ball-type saddle-equipped water faucet, the ball-type valve element is appropriately closed / opened by a rotating operation. For example, after the ball-type valve body is closed and water is stopped at the main body of the water faucet body, the attachment (FIG. 9 shows the appearance of a conventional attachment. In FIG. 9, the attachment 90 is shown as an example. A water stop device having an upper fastening portion 91 and an attachment main body 92) is attached to the attachment port of the water faucet main body, and the ball-type valve body is opened again so that the water faucet main body is inserted and attached. By inserting the main shaft of the water stop device to the deep part of the water faucet and closing the branch hole drilled in the water main pipe by expanding the tip of the main shaft, etc., it is completely possible to prevent water leakage even if the water faucet with saddle is removed. Stop water. In this completely water-stopped condition, it is possible to replace an old water faucet with a saddle with a new water faucet with a saddle, or a water faucet with a different saddle. It becomes.
This water stop device is also referred to as a saddle-equipped water faucet exchanger (hereinafter sometimes referred to as “exchanger”).

  In recent years, there has been an increasing demand for replacement of water faucets with saddles of different diameters. This is because, for example, the demand for water supply in the same site area increases due to apartment management and the two-household. In particular, the exchange from a 25 mm diameter water faucet to a 50 mm diameter water faucet is increasing. So far there has been no demand for 50 mm diameter water faucets. When replacing the water faucet with a saddle in this case (25 mm diameter → 50 mm diameter), first, when removing the plug with a diameter of 25 mm, attach the “25 mm diameter attachment” to the main shaft of the exchanger (cap The water faucet body is temporarily stopped by screwing it into the water faucet mounting port, and the diameter of the water main pipe is completely stopped by expansion of the tip of the main shaft. Remove the Saddle with Saddle (25 mm diameter attachment is also removed at the same time). Next, when installing a 50 mm diameter water faucet with a saddle, it is necessary to stop the water faucet body appropriately, so this time, an exchanger with a “50 mm diameter attachment” attached to the main shaft is used. The Rukoto.

  Thus, in the case of exchanging the saddle-equipped water faucets with different plug diameters, attachments with the respective plug diameters (in the example described above, a 25 mm diameter attachment and a 50 mm diameter attachment) are required.

  These attachments are made of copper castings as an example, and are heavy to carry. Especially, the types of attachments equipped in standard exchangers are 13 mm diameter to 25 mm diameter (of the same plug diameter) If there is a small 50mm diameter attachment, it will be significantly more important and capacity than other diameter attachments. Inconvenience occurs when transporting the container set.

  On the other hand, lids and plugs having a plurality of diameters already exist. As an example, a water purifier or the like that does not use an attachment according to the type and diameter of the faucet is provided (Patent Document 1).

  That is, Patent Document 1 discloses a connection tool that can be connected to a discharge port of a faucet having different diameters, and a thread portion is provided on the inner wall of the upper edge portion of a cylindrical and hard material that is open vertically. A first faucet connection portion is provided to form a cylindrical shape made of an elastic material opened vertically below the first faucet connection portion in the outer frame, and the inner diameter is larger than that of the first faucet connection portion. A faucet connector characterized by inserting a small second faucet connector is disclosed.

  Also, it can be used for 2 or 3 types of bolts of different sizes by attaching a detachable adapter to the cap and selecting this adapter while being attached to the protruding head of the bolt by screwing means. Caps that can be used are provided.

  That is, in Patent Document 2, a cylindrical main body having an upper wall having a lower end opened and an upper end having a screw hole for screwing in the upper end, and free rotation is prevented by the screw hole of the upper wall. And an adapter provided with a screw hole for screwing a bolt smaller in diameter than the screw hole in the center, and a lid screwed in a removable manner on an external screw formed on the outer peripheral surface of the main body There is disclosed a bolt cap in which the entire interior of the main body or at least the lower part of the main body has a space for storing a tightening nut to be screwed into the bolt.

  However, the faucet connector disclosed in Patent Document 1 connects the faucet by a threaded portion formed on the inner peripheral surface of the annular rib, and is assumed to be connected to a domestic faucet. Although the water faucet connector does not drop out of the water faucet at the level of the water flow of the spigot, the stability is not sufficient unlike the threaded connection with a helical screw or the like.

  In addition, the adapter disclosed in Patent Document 2 has a screw hole for screwing in and is detachable, and can be attached by being fitted into a recess provided in the upper part of the main body. There is a problem that the characteristics may not be sufficient, and there is a risk of loss.

  The present invention is an attachment comprising an insertion hole through which a main shaft of a water faucet exchanger with a saddle can be inserted, and a lid portion having a spiral groove that can be screwed into a water faucet attachment port with a saddle, The lid portion includes a plurality of lid portions having different diameters to be screwed into the attachment ports of the plurality of types of water cocks with saddles due to different diameters of the attachment ports.

  Further, each of the plurality of lid portions includes an outer lid portion and an inner lid portion each having a spiral groove on the inner side, and the inner lid inner spiral groove and the outer lid inner spiral groove when viewed from the bottom surface side of the lid portion. The starting surface coincides with the bottom surface of each lid portion.

  According to the present invention, it is possible to provide a saddle-attached faucet exchanger attachment that is convenient for water pipe work.
