    • A pipe joint is provided to connect and fix a pipe firmly against drawing force by integrally turning and securely fitting a displacement restricting ring in assembling a cap nut with a pipe joint body. A pipe joint is composed of a joint body(13) having a male screw part(19) and a cap nut(5) thread-connected to the male screw part of the joint body. A C-shaped displacement restricting ring(1) is composed of a cut portion formed in a circumference, and an inner blade formed in the end of the cut portion to cut a recessed groove(4) in an outer periphery(12a) of a pipe(12). An outer periphery of the C-shaped displacement restricting ring is arranged and contacted to a tapered inside(6) of a hole part(25) of the cap nut, and the cap nut and the C-shaped displacement restricting ring are integrally turned by a common turning unit. The common turning unit is composed of a recessed groove part axially formed in the tapered inside of the cap nut, and a fitting protruded part fitted to the recessed groove part and formed in the outer periphery of the displacement restricting ring.
    • 提供管接头,通过一体地转动并牢固地将位移限制环组装在具有管接头主体的盖帽螺母上,从而牢固地连接和固定管子。 管接头由具有阳螺纹部(19)的接头体(13)和与接合体的阳螺纹部螺纹连接的螺母(5)构成。 C形位移限制环(1)由形成在圆周上的切割部分和形成在切割部分的端部中的内刀片组成,以在其外周(12a)中切割凹槽(4) 管(12)。 C形位移限制环的外周被布置并接触到帽形螺母的孔部分(25)的锥形内部(6),并且帽形螺母和C形位移限制环通过 一个共同的车削单元。 公共转动单元由在螺母的锥形内侧轴向形成的凹槽部以及嵌合于凹槽部并形成在位移限制环的外周的嵌合突出部构成。

    • PURPOSE: A pipe joint is provided to improve endurance by protecting a connection portion of a pipe with a cover, and to connect the pipe firmly by checking displacement of a diameter extension piece through the transparent cover. CONSTITUTION: A pipe joint comprises a main body(2) having an insertion cylindrical part(3) fitted to the end of a pipe(1); a sealing member(4) mounted in a concave groove of the insertion cylindrical part; a slit mount clamp ring(5) combining the end of the pipe fitted to the insertion cylindrical part; and a diameter extension piece(6) fitted to the end of a slit(51) to extend the diameter of the clamp ring against the elastic force of the clamp ring, and displaced by contacting to the end of the pipe. The diameter extension piece is separated conveniently with pushing the pipe. The pipe is combined with the clamp ring without damage in the surface of the pipe, and sealing efficiency is improved with forming the slit. Working efficiency is improved with checking the displacement of the diameter extension piece.
    • 目的:提供一种管接头,通过保护具有盖子的管道的连接部分来提高耐久性,并通过检查直径延伸件通过透明盖的位移来牢固地连接管道。 构成:管接头包括主体(2),其具有安装在管(1)端部的插入圆柱形部分(3); 密封构件(4),其安装在所述插入圆柱形部分的凹槽中; 一个将安装在插入圆柱形部分上的管的端部组合的狭缝安装夹环5; 以及安装在狭缝(51)的端部上的直径延伸件(6),以克服夹紧环的弹力使夹紧环的直径延伸,并通过与管的端部接触而移位。 通过推动管道方便地分离直径延伸件。 管道与夹紧环组合,管道表面没有损坏,并且通过形成狭缝来提高密封效率。 通过检查直径延伸件的位移来提高工作效率。
