本考案は、例えばビニールハウスのビニールを巻き取るための連結用鋼管に関 する。 The present invention relates to a connecting steel pipe for winding vinyl in a greenhouse, for example.
【０００２】[0002]
従来の連結用鋼管としては、図７及び図８に示すものがある。このものは、大 略円筒状をなし一端の開口周縁部1aから長手方向に伸びる誘導溝2 を有する被挿 入部1 と、先細りのテーパ状をなして被挿入部1 の他端に連設され他の連結用鋼 管の被挿入部1 の開口周縁部1aと嵌合する嵌合部4 と、大略円筒状をなして嵌合 部4 に連設され他の連結用鋼管の被挿入部1 に挿入されるものであって他の連結 用鋼管の誘導溝2 に略重なって係止する係止溝6 を有する挿入部5 と、からなる 。 As a conventional connecting steel pipe, there is one shown in FIGS. 7 and 8. This product has a substantially cylindrical shape and is provided with an insertion portion 1 having a guide groove 2 extending in the longitudinal direction from an opening peripheral edge portion 1a at one end, and a tapered portion connected to the other end of the insertion portion 1. The fitting part 4 that fits into the opening peripheral edge 1a of the inserted part 1 of another connecting steel pipe, and the inserted part 1 of another connecting steel pipe that is connected to the fitting part 4 in a substantially cylindrical shape. And an insertion portion 5 having a locking groove 6 which is inserted into the guide groove 2 of another connecting steel pipe and is locked substantially overlapping with the guiding groove 2.
【０００３】 この連結用鋼管は、具体的には、所定長さを有する鋼管の一端部をスエージ加 工することによって嵌合部4 と挿入部5 が形成され、スエージ加工されない部分 が被挿入部1 をなす。また、誘導溝2 と係止溝6 は、絞り加工によって形成され る。Specifically, this connecting steel pipe has a fitting portion 4 and an insertion portion 5 formed by swaging one end portion of a steel pipe having a predetermined length, and a portion not swaged is a portion to be inserted. Make one The guide groove 2 and the locking groove 6 are formed by drawing.
【０００４】 ２本の連結用鋼管の連結は、一の連結用鋼管A の被挿入部1 に他の連結用鋼管 B の挿入部5 を挿入し、一の連結用鋼管A の被挿入部1 の開口周縁部1aと他の連 結用鋼管B の嵌合部4 を嵌合させることによってなされる。このようにして連結 された連結用鋼管は、例えばビニールハウスのビニールを巻き取るための回転軸 として用いられる。The two connecting steel pipes are connected by inserting the inserting portion 1 of the other connecting steel pipe B into the inserting portion 1 of the one connecting steel pipe A to insert the inserting portion 1 of the one connecting steel pipe A.

【０００５】[0005]
ところで、ビニールハウスのビニール巻き取りにおいては、連結された複数の 連結用鋼管が一様に回転しないと不都合が生じるので、上述のものは、一の連結 用鋼管A の誘導溝2 に他の連結用鋼管B の係止溝6 を係止させることにより、軸 回転方向に作用する力に対する連結強度を高め、連結用鋼管が個別に回転するこ とを防いでいる。 By the way, in the vinyl winding of a vinyl house, there will be inconvenience if the multiple connected steel pipes do not rotate uniformly. By locking the locking groove 6 of the steel pipe for use B, the connecting strength against the force acting in the axial rotation direction is increased, and the connecting steel pipes are prevented from rotating individually.
【０００６】 しかしながら、上述のものは、軸線方向の連結強度が弱いという問題点があっ た。すなわち、長年の間、巻き取り作業中に揺動させられたり、強風によって振 動させられたりして、一の連結用鋼管A の被挿入部1 の開口周縁部1aと他の連結 用鋼管B の嵌合部4 の間の嵌合状態が弛緩し、連結したものが外れてしまうこと がある。また、多数の連結用鋼管を連結する場合、既に連結し終わった部分が他 の部分を連結している間に揺動させられて外れてしまうことがある。However, the above-mentioned ones have a problem that the connecting strength in the axial direction is weak. That is, for many years, it has been oscillated during the winding operation or swayed by a strong wind, so that the opening peripheral edge portion 1a of the inserted portion 1 of one connecting steel pipe A and the other connecting steel pipe B The fitted state between the fitting portions 4 of may loosen and the connected one may come off. In addition, when a large number of connecting steel pipes are connected, a part that has already been connected may be swung and disconnected while connecting other parts.
【０００７】 本考案は、かかる事由に鑑みてなしたもので、その目的とするところは、堅固 に連結させることができる連結用鋼管を提供するにある。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connecting steel pipe that can be firmly connected.

【００１２】[0012]
以下、本考案の第１実施例を図１乃至図３に基づいて説明する。この連結用鋼 管は、例えばビニールハウスのビニールを巻き取るための回転軸として用いられ るものであり、大略円筒状をなし一端の開口周縁部1aから長手方向に伸びる誘導 溝2 を有する被挿入部1 と、先細りのテーパ状をなして被挿入部1 の他端に連設 され他の連結用鋼管の被挿入部1 の開口周縁部1aと嵌合する嵌合部4 と、大略円 筒状をなして嵌合部4 に連設され他の連結用鋼管の被挿入部1 に挿入されるもの であって他の連結用鋼管の誘導溝2 に略重なって係止する係止溝6 を有する挿入 部5 と、からなる構成は先の従来例と同様である。 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. This connecting steel pipe is used, for example, as a rotary shaft for winding vinyl in a greenhouse, and has a generally cylindrical shape, and has a guide groove 2 extending in the longitudinal direction from an opening peripheral edge 1a at one end. Part 1 and a fitting part 4 that is formed in a tapered shape and is connected to the other end of the inserted part 1 and that is fitted to the opening peripheral edge part 1a of the inserted part 1 of another connecting steel pipe, and a generally cylindrical shape. Locking groove 6 that is connected to the fitting part 4 and is inserted into the insertion part 1 of another connecting steel pipe and that substantially overlaps the guiding groove 2 of the other connecting steel pipe. The configuration including the insertion portion 5 having the is similar to that of the conventional example.
【００１３】 この連結用鋼管は、所定長さを有する鋼管の一端部をスエージ加工することに よって嵌合部4 と挿入部5 が形成され、スエージ加工されない部分が被挿入部1 をなす。また、誘導溝2 と係止溝6 は、絞り加工によって形成される。In this connecting steel pipe, the fitting portion 4 and the insertion portion 5 are formed by swaging one end portion of the steel pipe having a predetermined length, and the portion not swaged serves as the insertion portion 1. The guide groove 2 and the locking groove 6 are formed by drawing.
【００１４】 そして、被挿入部1 の壁面には、挿入された他の連結用鋼管の挿入部5 の壁面 を押圧するよう内方に突出する押圧突部3,3 を設けてある。この押圧突部3,3 は 、具体的には、被挿入部1 の壁面に外方からダボを打つことにより形成される。The wall surface of the inserted portion 1 is provided with pressing projections 3 and 3 that protrude inward so as to press the wall surface of the insertion portion 5 of another inserted connecting steel pipe. The pressing protrusions 3, 3 are specifically formed by hitting a dowel from the outside on the wall surface of the inserted portion 1.
【００１５】 ２本の連結用鋼管を互いに連結させるときは、一の連結用鋼管A の被挿入部1 に他の連結用鋼管B の挿入部5 を、係止溝6 が誘導溝2 に重なるように位置を合 わせて挿入する。このとき、挿入部5 の壁面と被挿入部1 の押圧突部3,3 が擦れ 合うことにより、強い摩擦抵抗が生じて挿入しにくいが、腕力によって押し込む ことは十分にできるので、挿入部5 を押し込み、一の連結用鋼管A の被挿入部1 の開口周縁部1aと他の連結用鋼管B の嵌合部4 を嵌合させる。When connecting two connecting steel pipes to each other, the inserting portion 1 of one connecting steel pipe A overlaps the inserting portion 5 of the other connecting steel pipe B, and the locking groove 6 overlaps the guiding groove 2. And insert it in the correct position. At this time, the wall surface of the insertion part 5 and the pressing projections 3, 3 of the insertion target part 1 rub against each other, which causes strong frictional resistance and makes it difficult to insert, but the insertion force is sufficient to insert the insertion part 5. Is pushed in to fit the opening peripheral edge portion 1a of the inserted portion 1 of the one connecting steel pipe A and the fitting portion 4 of the other connecting steel pipe B.
【００１６】 上述のようにして連結した連結用鋼管は、一の連結用鋼管A の被挿入部1 の開 口周縁部1aと他の連結用鋼管B の嵌合部4 が嵌合する上に、挿入部5 の壁面と押 圧突部3,3 の間に強い摩擦抵抗が生じるので、抜け外れにくい。従って、例えば 多数の連結用鋼管の連結作業中に、既に連結し終わった部分が、他の部分を連結 している間に揺動させられて抜け外れる可能性が低減し、連結作業を効率良く行 うことができる。また、ビニールハウスにおけるビニール巻取り作業に用いられ る場合、長年の間の巻き取り作業中の揺動や強風による振動によって抜け外れる 可能性が低減するので、点検、保守作業に費す時間を削減することができる。The connecting steel pipes connected as described above are such that the opening peripheral portion 1a of the inserted portion 1 of one connecting steel pipe A and the fitting portion 4 of the other connecting steel pipe B are fitted together. , A strong frictional resistance is generated between the wall surface of the insertion part 5 and the pressing projections 3, 3 so that it does not easily come off. Therefore, for example, during the connection work of a large number of steel pipes for connection, the possibility that the part that has already been connected will be swung and disconnected while connecting other parts is reduced, and the connection work can be performed efficiently. It can be carried out. Also, when used for vinyl winding work in vinyl greenhouses, the possibility of falling out due to rocking or vibration due to strong wind during winding work for many years is reduced, so the time spent for inspection and maintenance work is reduced. can do.
【００１７】 なお、連結用鋼管は、同一形状のものを複数連結させるに限らず、図４に示す ような、大略円筒状の鋼管の両端部をスエージ加工して嵌合部4 及び挿入部5 を 形成するとともに係止溝6 を設けてなる雄鋼管7 と、大略円筒状の鋼管の両端部 に誘導溝2 と押圧突部3,3 を設けてなる雌鋼管8 と、を交互に連結させるように してもよい。また、押圧突部は、突起状のものに限らず、例えば被挿入部の内周 に沿ってリング状に形成されたものでもよい。The steel pipes for connection are not limited to connecting a plurality of steel pipes having the same shape, and the fitting portion 4 and the insertion portion 5 are formed by swaging both ends of a substantially cylindrical steel pipe as shown in FIG. And the male steel pipe 7 having the locking groove 6 formed therein and the female steel pipe 8 having the guide groove 2 and the pressing projections 3 and 3 at both ends of the substantially cylindrical steel pipe are alternately connected. You may do so. Further, the pressing protrusion is not limited to a protrusion and may be formed in a ring shape along the inner circumference of the inserted portion, for example.
【００１８】 次に、本考案の第２実施例を図５及び図６に基づいて説明する。なお、第１実 施例のものと基本的な機能が同じ部材には同じ符号を付し説明を省略する。Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. The members having the same basic functions as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.
【００１９】 この連結用鋼管は、被挿入部1 の押圧突部3 が、誘導溝2 と重なるように設け られており、かつ、挿入部5 の係止溝6 の中間部が、押圧突部3 が引掛かるよう 幅狭に形成されている。In this connecting steel pipe, the pressing projection 3 of the inserted portion 1 is provided so as to overlap the guiding groove 2, and the intermediate portion of the locking groove 6 of the insertion portion 5 is the pressing projection. The width is narrow so that 3 can be hooked.
【００２０】 この連結用鋼管においては、一の連結用鋼管A の被挿入部1 に他の連結用鋼管 B の挿入部5 を係止溝6 が誘導溝2 に重なるように挿入するとき、押圧突部3 は 係止溝6 の側壁6a,6a 間を通ることになる。その結果、押圧突部3 が係止溝6 の 幅狭部9 に引掛かり、挿入部5 の挿入が一旦止まる。ここで、腕力によって挿入 部5 を押し込むと、押圧突部3 は幅狭部9 の側壁6a,6a 間を通らず幅狭部9 の上 方の空間を通る。このとき、押圧突部3 と幅狭部9 の間には、強い摩擦抵抗が生 じる。そして、押圧突部3 が幅狭部9 を通り過ぎることにより、挿入部5 の挿入 が再び進んで、一の連結用鋼管A の被挿入部1 の開口周縁部1aと他の連結用鋼管 B の嵌合部4 が嵌合する。In this connecting steel pipe, when inserting the inserting portion 5 of the other connecting steel pipe B into the inserted portion 1 of one connecting steel pipe A so that the locking groove 6 overlaps the guiding groove 2, The protrusion 3 passes between the side walls 6a, 6a of the locking groove 6. As a result, the pressing protrusion 3 is caught by the narrow portion 9 of the locking groove 6, and the insertion of the insertion portion 5 is temporarily stopped. Here, when the insertion portion 5 is pushed in by an arm force, the pressing protrusion 3 passes through the space above the narrow portion 9 without passing between the side walls 6a, 6a of the narrow portion 9. At this time, a strong frictional resistance is generated between the pressing protrusion 3 and the narrow portion 9. Then, when the pressing protrusion 3 passes through the narrow portion 9, the insertion of the insertion portion 5 progresses again, and the opening peripheral edge portion 1a of the inserted portion 1 of the one connecting steel pipe A and the other connecting steel pipe B are connected. Fitting part 4 fits.
【００２１】 かかる連結用鋼管は、押圧突部3 が係止溝6 の幅狭部9 を通るときだけ強い摩 擦抵抗が生じるので、連結された連結用鋼管が抜け外れにくくなる上に、挿入部 5 の抜き差しを省力的に行うことができる。In such a connecting steel pipe, a strong friction resistance is generated only when the pressing projection 3 passes through the narrow portion 9 of the locking groove 6, so that the connected connecting steel pipes are hard to come off and are inserted. Part 5 can be inserted and removed labor-savingly.
【００２２】[0022]
請求項１記載の連結用鋼管は、被挿入部の壁面に、挿入された他のものの挿入 部の壁面を押圧するよう内方に突出する押圧突部を設けることにより、挿入部の 壁面と押圧突部の間に強い摩擦抵抗が生じる。従って、連結された連結用鋼管が 抜け外れにくくなる。 The connecting steel pipe according to claim 1, wherein the wall surface of the inserted portion is provided with a pressing protrusion projecting inward so as to press the wall surface of the inserted portion of another inserted member, thereby pressing the wall surface of the inserted portion against the wall surface of the inserted portion. A strong frictional resistance occurs between the protrusions. Therefore, the connected connecting steel pipes are unlikely to come off.
【００２３】 また、請求項２記載の連結用鋼管は、請求項１記載の効果の上に、押圧突部を 、誘導溝と重なるように設けるとともに、挿入部の係止溝の中間部を、押圧突部 が引掛かるよう幅狭に形成することにより、押圧突部が係止溝の幅狭の部分を通 るときだけ強い摩擦抵抗が生じる。従って、挿入部の抜き差しを省力的に行うこ とができる。In addition, according to the steel pipe for connection of claim 2, in addition to the effect of claim 1, the pressing protrusion is provided so as to overlap with the guide groove, and the intermediate part of the locking groove of the insertion part is By forming the pressing protrusion so narrow that it can be caught, a strong frictional resistance is generated only when the pressing protrusion passes through the narrow portion of the locking groove. Therefore, the insertion / removal of the insertion portion can be performed labor-savingly.
