いる。[Prior Art and its Problems] The applicant has already proposed this type of semi-male fitting for water supply as Utility Model Registration No. 2516907. This known semi-male metal fitting is configured such that the locking portion on the tip side of the metal fitting body and the locking projection of the sliding tube can be selected and engaged according to the inner diameter of the hose joint. A bulging step is formed on the outside of the base end of the main body, and a small diameter portion is formed by the taper step provided on the inner wall of the base end of the sliding tube. The portion is arranged close to the bulging step portion of the main body, and the packing disposed on the step portion forms a watertight state between the two. Therefore, even if the hose joint is engaged with the latter locking projection, the watertight state is maintained. When the sliding pipe is retracted, the gap between the main body and the sliding pipe is enlarged to release the watertight state, so that the gap between the main body and the sliding pipe can be communicated in the axial direction. The metal fittings can be washed by using such as.

テナンスに苦慮していた。However, powdery substances such as mud, sand, and dust that have entered between the main body of the semi-male pipe and the sliding pipe in fire fighting activities using water stored in a water tank or pond, river water, etc.
If the water supply is stopped and the product is dried, it will harden extremely strongly. Even if you try to clean with tap water from a small gap, these substances cannot be completely removed because the water cannot be supplied to the back of the sliding pipe by providing a smooth flow, and it hardens especially near the packing. Since the powdery substances that are present are in a recessed position, the removal of these substances becomes insufficient by washing with tap water, resulting in damage to the packing. Regarding the semi-male pipes used for fire extinguishing equipment installed in the building, tap water is used, so there is no risk of powdery substances such as mud, sand, dust, etc. adhering to it, Due to the drying of air, the packing deteriorated quickly, which made maintenance difficult.

で洗浄水を容易に到達させることができる。Operation of the Technical Means In the first technical means, the sliding tube 3 is formed by cutting out the sliding tube 3 because the sliding tube 3 is provided with a notch 5 having a substantially U-shape on the base end side. The open portion can be brought close to the position of the packing 7. Since the inclined wall 6 is provided outward from the bottom of the cutout portion 5 and is projected from the outer cylinder 9 having the tip end thereof retracted, the outer cylinder and the sliding pipe are located at the cutout portion 5 and the inclined wall 6. The opening can be formed larger than the gap 8 between Therefore, it is possible to introduce the cleaning water into the inside of the sliding tube 3 while applying the water flow by using the notch 5 and the inclined wall 6 and easily reach the position of the packing 7.

望ましい。Since the watertight state with the main body 1 is released when the sliding tube 3 is advanced, the powdery substance appropriately passes through the gap 8 and is discharged to the outside from the front and rear sides of the gap 8 together with the washing water. I will go. When the cleaning water is supplied while rotating the sliding tube 3, the cleaning water can be supplied to the entire gap 8 between the sliding tube 3 and the metal fitting body 1. It should be noted that the number of the cutouts 5 can be at least one so that cleaning is possible, but it is desirable to provide a plurality of cutouts 5 in order to improve cleaning efficiency.

ることもできる。In the second technical means, the small hole 11 is penetrated from the outside of the sliding tube 3 toward the front of the packing 7. The gap 8 with the metal fitting body 1 is communicated with the outside. Therefore, when the cleaning water is supplied from the small holes 11, the cleaning water forming the water flow in the gap 8 can be supplied. When the cleaning water is supplied in a state where the watertight state between the sliding tube 3 and the main body 1 is released, the powdery substance is appropriately dispersed in the gap 8.
After passing through, the cleaning water is discharged to the outside from the front and rear sides of the sliding tube 3. Also in this case, if the cleaning water is supplied while rotating the sliding tube 3, the cleaning water can be supplied to the entire gap 8 between the sliding tube and the main body 1. This small hole 11 can be washed with at least one small hole. At the time of non-cleaning, it will be closed with a screw or the like not shown. The small holes 11 can also be used to inject oil or the like.

If a sloped wall is provided from the bottom of the notch toward the inside and the tip is located in front of the contact with the packing, the cleaning water can be supplied to the packing more smoothly. (Refer to claim 4). Further, when the small hole is obliquely penetrated from the front part of the locking projection toward the gap between the metal fitting body and the sliding tube, the cleaning water can be supplied toward the packing, so that the cleaning efficiency can be improved. (Refer to claim 5).
