この考案は、プラグとソケットからなる所謂迅速管継手
のソケットにおける防塵構造の改良に、係るものである
。[Detailed Description of the Invention] This invention relates to an improvement in the dust-proof structure of a so-called quick pipe joint socket consisting of a plug and a socket.
上記形式の迅速管継手においては、プラグの外周に形式
された施錠用溝にソケット側に配設された施錠用法を係
合させる事によってプラグとソケットとを接続させると
共に、ソケットの外周に嵌挿した操作環によってこの接
続状態を解錠して両者を分離させる様になっている。In the above-mentioned type of quick fitting, the plug and socket are connected by engaging the locking groove provided on the socket side with the locking groove formed on the outer periphery of the plug, and the fitting is inserted into the outer periphery of the socket. An operating ring is used to unlock this connection and separate the two.
ところでプラグとソケットとが分離状態にあるとき、特
にソケットの開口部は露出状態になるため、付塵しやす
い。By the way, when the plug and the socket are separated, the opening of the socket in particular is exposed and is prone to attracting dust.
これを防止するために、防塵用の保護キャップを用いる
事は従来から知られているが、従来の保護キャップの構
造にあっては、特に非使用時に保護キャップが管継手か
ら脱落してゴム管上を遊歩したり、又は紛失する欠点が
あった。In order to prevent this, it has long been known to use dust-proof protective caps, but with the structure of conventional protective caps, the protective caps fall off from the pipe joints, especially when not in use, causing the rubber pipes to leak. There was a drawback that it could be walked around on or lost.
この考案の目的は、使用時には充分信頼できる防塵効果
を与え、しかも非使用時においても管継手から脱落する
事のない様な保護キャップを備えた管継手のソケットを
、提供する事にある。The purpose of this invention is to provide a socket for a pipe joint that provides a sufficiently reliable dust-proofing effect when in use and is equipped with a protective cap that will not fall off from the pipe joint when not in use.
以下、図面に示す実施例によって、更に具体的に説明す
る。The present invention will be explained in more detail below with reference to embodiments shown in the drawings.
１０はプラグで、ソケット２０側の施錠体２２が係合す

ている。A sliding valve 34 which is resiliently repelled by a spring 33 is interposed in the annular space between the main cylinder part 26 and the valve pushing part 28, and the backing 36 of the sliding valve comes into contact with the plug 10 to close the plug. 10
and the socket) 20.
主筒部２６の外周には、施錠体２２を求心方向に押圧す
る内周斜設を有した操作環３８がバネ４０に弾撥されて
摺動可能に嵌合され、かつ該操作環の一部と該バネとを
覆うように外套体４２が嵌着されている。An operation ring 38 having a diagonal inner circumference that presses the locking body 22 in a centripetal direction is fitted to the outer periphery of the main cylinder portion 26 so as to be slidable while being elastically resilient to a spring 40. A mantle 42 is fitted to cover the spring and the spring.
ソケット主体３２には外周溝４４が形成されて、該外套
体の内周爪４６がこれに係着している。An outer circumferential groove 44 is formed in the socket main body 32, and an inner circumferential claw 46 of the mantle is engaged with the outer circumferential groove 44.

段に向ってゴム管接続部３０にはテーパ面５２（または
、一定の曲率半径をもった曲面）が形式されている。For this reason, the two cannot separate. An outer circumferential step 50 is formed following the back portion 48 of the mantle, and a tapered surface 52 (or a curved surface with a constant radius of curvature) is formed on the rubber tube connecting portion 30 toward the outer circumferential step. ing.
第１図に示す構造では、外周段部５０が外套体４２に形
成されているが、第２図に示す例のごとく、該外周段部
をゴム管接続部３０に形式してもよい。In the structure shown in FIG. 1, the outer circumferential step portion 50 is formed on the mantle 42, but the outer circumferential step portion may be formed into the rubber tube connecting portion 30 as in the example shown in FIG.

０によって容易に離脱しないようになればよい。In either case, an outer circumferential groove 60 is formed by the back portion 48, outer circumferential step portion 50, and insertion rubber tube 54, and the socket 20
The base ring 58 of the protective cap 56 that is inserted into the plug connection opening of
It is sufficient if the value 0 prevents the user from leaving easily.

図示の如く放射状方向に拡げられるための外周溝６０が
形成できるようになる。When the rubber tube 54 has a large wall thickness, the outer circumferential groove can be easily formed, but when the wall thickness is small, the rubber tube connecting portion 30
The tapered surface or curved surface 52 of the opening end
As shown in the figure, an outer circumferential groove 60 can be formed to expand in the radial direction.
プラグ１０とソケツ） ２０とを接続し或いは分離する

、塵埃が入り込むのを防止することができる。This invention uses a protective cap to protect the open end of the socket, that is, the end that connects to the plug, and is unique in that it prevents this protective cap from falling off. The side diameter is smaller than that of the connecting end side, and a stepped portion is provided on the outer periphery of the central portion, and a protective cap to be fitted into the opening of the connecting end is provided with a series of base rings, and the base ring is connected to the base ring. Because it fits into the outer step, the protective cap will not come off from the socket when the socket is connected to the rubber tube, and when the plug is not connected, it will always protect the end connected to the plug. Therefore, it is possible to prevent dust from entering.
