Description

  TECHNICAL FIELD The present invention relates to a water stop coupling device for tubular bodies that can connect water pipes as horticultural supports and the like to secure water stop and connect them easily and firmly, yet separably.

  When cultivating tomatoes and eggplants, if rainwater adheres to them, pests are generated and the tomatoes are liable to crack or rot. Therefore, for example, a simple rain guard a as shown in FIG. 36 is used to prevent such damage.

  The rain guard a has a plurality of pipe-shaped U-shaped struts e in one direction in which the upper portion b is bent in an inverted U shape and the lower end portions d and d of the strut portions c and c on both sides are buried in the soil. 37, the upper end portion f of the U-shaped support column e and the both side portions g, g thereof are connected by a pipe-like horizontal connecting rod h, and the support frame j shown in FIG. And a rain protection sheet m is placed on the upper portion k of the support frame j. As shown in FIG. 37, the U-shaped support column e includes an arched pipe n, straight upper pipes q and q connected to both lower ends p and p thereof, and lower ends of the linear upper pipes q and q. It consisted of straight lower pipes s, s connected to r. The horizontal splice h was composed of two straight horizontal pipes t, t connected to each other.

  For assembling the U-shaped support column e and the horizontal connecting rod h, for example, a joint pipe insertion method similar to that disclosed in Japanese Patent Application Laid-Open No. 2002-814020 has been adopted. That is, with respect to the U-shaped support column e, as shown in FIGS. 38 to 39, a joint pipe v to be inserted into the lower end portion u of the arched pipe n is integrally projected at the upper end of the linear upper pipe q. In addition, a joint pipe v that is inserted into the lower end portion w of the linear upper pipe q protrudes from the upper end of the linear lower pipe s. A conical cap x that narrows downward was fitted to the lower end of the straight lower pipe s. As for the horizontal splice h, as shown in FIGS. 40 to 41, a joint pipe v is inserted at one end of one linear horizontal pipe t1 and inserted into an end portion y of the other linear horizontal pipe t2. It was. Note that a cap z was fitted to the outer ends of the two laterally connecting rods h and h.

  The conventional rain guard a employs an assembly method in which short pipes are detachably connected to each other for convenience of storing the rain guard after harvesting of tomatoes and the like at a store. This was to reduce the sales space.

  However, as described above, the pipes in the rain guard a having the above-described configuration employ a joint pipe insertion method in which the joint pipe v projecting from one pipe is inserted into the end portion of the other pipe. Therefore, when the wind blows into the inside of the rain guard during use as a rain guard, the joint pipe v may come off from the end part due to the arch-shaped part i floating. Further, after the lower end portions d and d of the U-shaped support column e are pierced into the soil, there is a problem that the joint pipe v comes off from the end portion when the U-shaped support column is pierced again to correct the piercing state. Repair work was difficult.

Also, since the pipes were connected to each other by inserting the joint pipe into the end part, storms occurred inside the pipes when rainwater entered the pipes from the joints between the pipes, and the pipe strength deteriorated. There was also an easy problem.
