In particular, the quick connector can be operated in a short time and with a simple operation, and even if an external force is inadvertently applied, The present invention relates to a safety lock ratchet structure that is highly safe because it prevents the occurrence of injury or accident due to disconnection of the pipe joint.

一般の管継手の構造は、接続管と管継手とを結合する際、管継手内に接続管を挿入し、接続管により管継手の位置決め部内のパッド、パッキン、内ばね、位置決め体などの部品を押下し、位置決め体の上部に配設した鋼球が位置決め体の中心へ向かって移動し、環溝内に接続管が進入して接続管を係合する際、接続管と管継手とが結合され、接続管の環溝内に鋼球が係入されると、位置決め体に外嵌され、鋼球により当接されて位置決めされる可動スリーブもこのときに鋼球がその斜縁から外れ、外ばねの回復力により上頂へ向かって位置決め体に当接される。接続管を取り外すときは、可動スリーブを押下し、鋼球が可動スリーブに当接される斜縁の位置まで戻ると、接続管を容易に取り外すことができる。 In general pipe joint structure, when connecting the connecting pipe and the pipe joint, the connecting pipe is inserted into the pipe joint and the pad, packing, inner spring, positioning body, etc. in the positioning part of the pipe joint are connected by the connecting pipe. When the steel ball arranged on the upper part of the positioning body moves toward the center of the positioning body and the connection pipe enters the ring groove and engages the connection pipe, the connection pipe and the pipe joint When the steel ball is engaged and inserted into the annular groove of the connecting pipe, the movable sleeve which is externally fitted to the positioning body and is positioned by contact with the steel ball is also detached from the oblique edge at this time.

When the movable collar 5 is brought into contact with the movable collar 5 and is restored by the accumulation of the compression coil spring 2, it is ejected outward and removed.

ラチェット構造７は、ギヤシフトリング７１を有し（図２を参照する）、金属材料又はプラスチック材料からなり、全体的に中空状を呈し、コネクタ本体１の枢着端１１の周囲隅部に対応した形状を有する位置決め凹溝７１１が内周壁に形成され、これによりギヤシフトリング７１がコネクタ本体１の延伸端１２に嵌合されると位置制限された状態となり、ギヤシフトリング７１の外周壁には、取り囲むように設けられて対応し合う２つの案内杆７１２と、可動カラー５に凹設された第１の嵌合孔５２の内周壁と対応した形状を有する２つのラチェットユニット７２とを有し（図２及び図３を参照する）、２つのラチェットユニット７２には、押圧防止領域７２１が形成される。押圧防止領域７２１は、制動歯７２１１と、押圧防止領域７２１の一側に位置して連通し合う押圧領域７２２と、を有する。押圧領域７２２は、全体的に長尺形状を呈する。 The ratchet structure 7 has a gear shift ring 71 (see FIG. 2), is made of a metal material or a plastic material, has a hollow shape as a whole, and corresponds to a peripheral corner of the pivot end 11 of the connector body 1. A positioning concave groove 711 having a shape is formed on the inner peripheral wall, so that when the gear shift ring 71 is fitted to the extended end 12 of the connector main body 1, the position is restricted, and the outer peripheral wall of the gear shift ring 71 is surrounded. Two guide rods 712 that are provided and correspond to each other, and two ratchet units 72 having a shape corresponding to the inner peripheral wall of the first fitting hole 52 that is recessed in the movable collar 5 (see FIG. 2 and FIG. 3), the two ratchet units 72 are formed with a pressing prevention region 721. The pressure prevention area 721 includes braking teeth 7211 and a pressure area 722 that is located on one side of the pressure prevention area 721 and communicates therewith. The pressing area 722 has a long shape as a whole.

ラチェット構造７のギヤシフトリング７１とコネクタ本体１の延伸端１２とは一体成形され、コネクタ本体１の別の構造に成形してもよい（図４を参照する）。さらに詳細に述べると、ラチェット構造７のギヤシフトリング７１とコネクタ本体１の延伸端１２とが一体成形される際、ギヤシフトリング７１の２つの案内杆７１２がコネクタ本体１の枢着端１１の外周壁に形成され、取り囲むように設けられて対応し、コネクタ本体１の別の構造については前述されているため、ここでは繰り返して述べない。 The gear shift ring 71 of the ratchet structure 7 and the extending end 12 of the connector body 1 may be integrally formed, and may be formed into another structure of the connector body 1 (see FIG. 4). More specifically, when the gear shift ring 71 of the ratchet structure 7 and the extended end 12 of the connector body 1 are integrally formed, the two guide rods 712 of the gear shift ring 71 are connected to the outer peripheral wall of the pivot end 11 of the connector body 1. Since the other structure of the connector main body 1 has been described above, it will not be repeated here.

また、コネクタ本体１の枢着端１１には、接続部材８を組み合わせる。接続部材８は、金属材料又はプラスチック材料からなるとともに、接続部材８の両端を挿通させる貫通孔８０を有する。接続部材８は、結合端８１、着脱端８２及び連結端部８３を有する。結合端８１の外周面には、雄ねじ領域８１１が設けられる。着脱端８２は、多角形状を呈して結合端８１の一端に設けられる。連結端部８３は、着脱端８２の一端に突設されている。連結端部８３は、コネクタ本体１の枢着端１１に取り付けられる。 Further, the connecting member 8 is combined with the pivot end 11 of the connector body 1. The connection member 8 is made of a metal material or a plastic material and has a through hole 80 through which both ends of the connection member 8 are inserted. The connection member 8 has a coupling end 81, a detachable end 82 and a coupling end 83. A male screw region 811 is provided on the outer peripheral surface of the coupling end 81. The detachable end 82 has a polygonal shape and is provided at one end of the coupling end 81. The connecting end 83 projects from one end of the detachable end 82. The connecting end portion 83 is attached to the pivot end 11 of the connector main body 1.

前述したコネクタ本体１の枢着端１１及び接続部材８の連結端部８３には、雌ねじ領域１１１，８３２及び雄ねじ領域１１２，８３１がそれぞれ形成される。 Female screw regions 111 and 832 and male screw regions 112 and 831 are formed in the pivot end 11 of the connector main body 1 and the connecting end 83 of the connection member 8, respectively.

コネクタ本体１の枢着端１１は、全体的に雌ねじ領域１１１を有するタイプに形成される。接続部材８の連結端部８３には、全体的に雄ねじ領域８３１が形成される（図５を参照する）。 The pivot end 11 of the connector body 1 is formed in a type having a female thread region 111 as a whole. A male thread region 831 is formed as a whole at the connecting end 83 of the connecting member 8 (see FIG. 5).

コネクタ本体１の枢着端１１に全体的に雄ねじ領域１１２が形成される場合、接続部材８の連結端部８３には全体的に雌ねじ領域８３２が形成される（図６を参照する）。 When the external thread region 112 is formed entirely at the pivot end 11 of the connector body 1, the internal thread region 832 is formed entirely at the connection end portion 83 of the connecting member 8 (see FIG. 6).

このように、可動カラー５がコネクタ本体１の延伸端１２に嵌合されると、可動カラー５の第１の嵌合孔５２の内周壁に設けた２つのラチェットユニット７２は、コネクタ本体１の延伸端１２に設けたギヤシフトリング７１に対応し、圧縮コイルばね２及び押動リング座４を利用すると可動カラー５が変位可能な状態となる。 As described above, when the movable collar 5 is fitted to the extending end 12 of the connector main body 1, the two ratchet units 72 provided on the inner peripheral wall of the first fitting hole 52 of the movable collar 5 are connected to the connector main body 1. Corresponding to the gear shift ring 71 provided at the extended end 12, when the compression coil spring 2 and the push ring seat 4 are used, the movable collar 5 becomes displaceable.

そのため、コネクタ本体１の延伸端１２に外部の継手９を挿設する際、コネクタ本体１のチャンバ１０に継手９を挿入し、コネクタ本体１の延伸端１２に位置する可動カラー５が自動的に上方へ変位し、可動カラー５が一方向で回転すると、ラチェット構造７のギヤシフトリング７１の２つの案内杆７１２が２つのラチェットユニット７２の各押圧防止領域７２１の制動歯７２１１へ移動し、可動カラー５が係止状態となり、不用意に可動カラー５に外力が加わっても、外部の継手９が外れることを防ぐことができる（図７、図８及び図９を参照する）。 Therefore, when the external joint 9 is inserted into the extended end 12 of the connector body 1, the joint 9 is inserted into the chamber 10 of the connector body 1, and the movable collar 5 positioned at the extended end 12 of the connector body 1 is automatically When the movable collar 5 is displaced upward and rotated in one direction, the two guide rods 712 of the gear shift ring 71 of the ratchet structure 7 are moved to the braking teeth 7211 of the press prevention regions 721 of the two ratchet units 72, and the movable collar 5 Even if an external force is applied to the movable collar 5 carelessly, the external joint 9 can be prevented from coming off (see FIGS. 7, 8, and 9).

また、可動カラー５が他方向へ回転すると、ラチェット構造７のギヤシフトリング７１の２つの案内杆７１２が２つのラチェットユニット７２の押圧領域７２２へ移動し、可動カラー５が非係止状態となり、押圧すると外部の継手９を外すことができる（図７、図１０及び図１１を参照する）。このように、本考案の安全ロックラチェット構造は、クイックコネクタを短時間及び簡便な手間で操作することができる上、不用意に外力が加わっても外部の管継手が外れて怪我又は事故が起きることを防ぐことができるため安全性が高い。 When the movable collar 5 is rotated in the other direction, the two guide rods 712 of the gear shift ring 71 of the ratchet structure 7 are moved to the pressing areas 722 of the two ratchet units 72, and the movable collar 5 is brought into the non-locking state. Then, the external joint 9 can be removed (see FIG. 7, FIG. 10 and FIG. 11). As described above, the safety lock ratchet structure of the present invention can operate the quick connector in a short time and with simple labor, and even if an external force is applied inadvertently, the external pipe joint is detached and an injury or accident occurs. Safety is high because it can be prevented.
