に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hose joint having a nipple portion whose outer circumferential surface has an uneven shape in order to improve sealing properties and prevention properties.
従来、上記タイプのニップル部は、通常金属管を旋盤等
により切削加工して外周面に凹凸形状を形成していた。Conventionally, the above-mentioned type of nipple portion has been formed by cutting a metal tube using a lathe or the like to form an uneven shape on the outer circumferential surface.

ニップル部の外周面に上記のような凹凸形状を形成する
ことはほとんど不可能であった。However, this cutting process increases the number of man-hours, and also causes damage to the inner circumferential surface of the hose due to contact between the inner circumferential surface of the rubber or synthetic resin hose and the uneven edges on the outer circumference of the nipple. □ This is a cause of lower sealing capacity and lower pressure resistance. It was difficult to design the uneven shape because it was necessary to prevent the formation of squares. Also,
In a hose joint where the sleeve part and nipple part are integrally cut from a forged metal bar,
It has been almost impossible to form the above-described uneven shape on the outer peripheral surface of the nipple portion.

The hose joint of the invention achieves the above object by forming a nipple portion by integrating a cylindrical body made of rubber or synthetic resin with an uneven outer circumferential surface onto the outer circumferential surface of a metal pipe by molding. be.
以下、この発明の実施例を、図例に基づいて説明する。Hereinafter, embodiments of the present invention will be described based on illustrated examples.

リーブ７が保合可能となっているものである。The embodiment shown in FIG. 1 is an example in which one end of one metal pipe l forming a fluid metal pipe is applied to a nipple portion 2 joint. In this case, when applied to fluid metal piping such as brake hydraulic piping and fuel piping in automobiles, the fluid to which this embodiment is applied will not only have the effects of the present invention but also lead to a significant reduction in the number of manufacturing steps. The metal pipe has a nipple part 2 at one end of the metal pipe 1, and an eye joint 4 at the other end.
are welded to each other, and a sleeve 7 can be secured to the annular bulge 5 at the base of the nipple.

を型成形することが望ましい。Here, the nipple part 2 is formed by molding a cylindrical body 10 made of rubber or synthetic resin material and having a desired uneven shape on the outer peripheral surface on the outer peripheral surface of the metal tube 1 on the side beyond the annular bulging part 5. It is formed in an integrated manner. The molding method is injection,
Either transfer or compression may be used, and the material of the cylindrical body 10 is usually the same type of rubber (NBR, Co, etc.) or synthetic resin (FA, etc.) depending on the material of the hose to be fastened. In addition, in order to ensure the integration of the metal tube 1 and the cylindrical body 10, the cylindrical body 10 is attached after applying adhesive to the outer peripheral surface of the metal tube 1.
It is desirable to mold the

着現象が生じシール性向上に寄与する。As shown in FIG. 2, after fitting the nipple part 2 into the hose 11, the inlet tube 7 is caulked (in two places in the example shown) to fasten the hose 11 to a joint at one end of the fluid metal pipe. At this time, since the material forming the uneven shape of the nipple portion 2 is rubber or synthetic resin, it is softer than metal and there is no risk that the inner circumferential surface of the hose will be damaged by the uneven edges of the nipple portion. Further, when the cylindrical body 10 and the hose 11 are both molded from the same type of rubber material, a phenomenon of crosslinking and adhesion occurs over time at the interface between the two, contributing to improved sealing performance.

This is an example in which the metal tube 14 for forming the nipple portion is applied to a hose joint formed by integrally cutting a forged metal rod.
A nipple portion 18 is formed by integrating a cylindrical body 17 on the outer peripheral surface of 4 by molding. The manner of use of this embodiment, ie, the method of connecting the hose to the joint, is the same as in the above embodiment. Note that the hose joint of the present invention, in which reference numeral 20 in the figure is a female threaded portion, has the above-described configuration, and therefore has the following effects.
（ア）ニップル部外周面の凹凸形状の形成を型成形によ

容易となる。(b) Since the material forming the uneven nipple shape is rubber or synthetic resin, it is much softer than metal, and when designing the uneven shape, it is necessary to take into consideration the possibility of damage caused by the uneven edges of the inner peripheral surface of the hose. This makes it easy to design uneven shapes.

Easy to form an uneven shape on the outer circumference of the nipple.
