惟,由於該覆塑層14與該密封圈15可滑動地套設在該波紋管2,因此,在安裝時,有容易滑動不易定位的缺點。However, since the plastic covering
且該閥體13是由二個半部對合而成,除了存在有縫隙外,且該密封圈15雖然可以提升該接頭基體12與該覆塑層14間的氣密效果,但該覆塑層14與該波紋管2間同樣存在有間隙,以致於整體的止漏效果不如預期。And the
因此,本發明之目的,即在提供一種能夠提升氣密性與止漏效果的管接頭及其套環製造方法。Therefore, the purpose of the present invention is to provide a pipe joint and a method for manufacturing the collar that can improve airtightness and anti-leakage effects.

該套環包括一內環壁、一環繞該內環壁且與該內環壁界定出一環隙的外環壁,及連接該內環壁一端與該外環壁一端的抵靠壁,該內環壁穿置在該波紋管內,並具有一由內表面凹陷且突出於外表面的螺旋紋路,該螺旋紋路螺合於該波紋管,該外環壁套置在該波紋管外,該抵靠壁抵靠於該波紋管一端。The collar includes an inner ring wall, an outer ring wall surrounding the inner ring wall and defining an annular gap with the inner ring wall, and an abutment wall connecting one end of the inner ring wall and one end of the outer ring wall, the inner ring wall The ring wall is inserted into the bellows, and has a helical pattern that is recessed from the inner surface and protrudes from the outer surface. The wall leans against one end of the bellows.
該止漏環環繞該波紋管,並包括一穿置在該環隙且迫抵於該抵靠壁的塞環部,及一反向於該塞環部且受迫於該第二管件之擋止部的迫抵部。The anti-leakage ring surrounds the bellows and includes a plug ring portion inserted in the annular gap and pressed against the abutting wall, and a stopper opposite to the plug ring portion and forced by the second pipe member The pressing part of the stop.
一種管接頭的套環製造方法,以一金屬板材為原料,並包含下列步驟:A method for manufacturing a collar of a pipe joint, which uses a metal plate as a raw material, and includes the following steps:
沖壓該板材成為一環件,該環件一體成型有該內環壁、該外環壁與該抵靠壁。The plate is punched to form a ring, and the ring is integrally formed with the inner ring wall, the outer ring wall and the abutting wall.
使該內環環繞一擠壓件,並接觸於該擠壓件的一凸部。The inner ring surrounds an extruded part and contacts a protrusion of the extruded part.
在該內環與該凸部相對位移且該內環與該擠壓件二者其中一者轉動的過程中,擠壓該內環壁形成該螺旋紋路。During the relative displacement of the inner ring and the protrusion and the rotation of one of the inner ring and the extruding part, the inner ring wall is extruded to form the spiral pattern.
本發明之功效在於:以層層套接的套環、波紋管、止漏環,大幅提升氣密性與止漏效果,且在螺旋紋路通過特殊之擠壓方式成型的情形下,使該套管能夠一次沖壓成型,而大幅縮短製造時間。The effect of the present invention lies in that the sleeve rings, bellows, and leak-proof rings connected in layers can greatly improve the air-tightness and leak-proof effects, and when the spiral pattern is formed by a special extrusion method, the sleeve The tube can be stamped and formed in one pass, significantly reducing manufacturing time.
