Description

[Detailed Description of the Invention] (Industrial field of application) This invention prepares a large number of pipes that are made by joining half-divided pipes, and adds them in series through an annular joint material to connect cables and the like inside. The present invention relates to a flexible split tube for cable protection in which a flexible split tube that stores and protects it can be flexibly connected and that has a waterproof structure.

(Prior Art) Most of the tubes for protecting the cables of this type are perfect circles, and few of them are waterproof type to prevent water intrusion. In addition, it is difficult to waterproof the mating surfaces of the ones made by butting the half-split tubes, and those having a waterproof structure have not been used.

Therefore, as in Japanese Utility Model Laid-Open No. 62-54526, a packing material for covering the halved pipe is provided along the longitudinal butting portion, and a packing material for covering the both ends of the substantially annular joint material is provided. Were developed.

In this method, two adjacent pipes are arranged in a straight line, and their butt ends are covered with a joint material.

(Problems to be Solved by the Invention) In Japanese Utility Model Laid-Open No. 62-54526, a packing material is provided on both end edges of a substantially annular joint material so as to cover these end edges. Therefore, when connecting in a straight line, the packing material at both end edges of the joint material contacts the entire outer circumference of the end portion of the pipe,
Although a waterproof effect is obtained, when the adjacent pipes are bent and connected, the packing materials at both end edges of the joint material do not contact the entire outer circumferences of the end portions of the two adjacent pipes. Therefore, a gap is created between the outer circumference of the pipe and the joint material, and water may enter through this gap.

As described above, the conventional one is not completely waterproof, and especially when the protective tube is bent and connected, the joint is not completely waterproof.

Therefore, the present invention provides a universal split tube that is made of a joint material that can ensure a waterproof effect even when bending and connecting a plurality of flexible split tubes for cable protection, and which is a simple joint material for connecting multiple flexible split tubes. It is intended to solve the above problems by providing them.

(Means for Solving the Problem) The present invention constructs a pipe by abutting half-split pipes, prepares a large number of these pipes, and covers the abutting ends of two adjacent pipes with a substantially annular joint material. , A flexible split tube made by flexibly connecting a plurality of tubes, with a packing material interposed between the longitudinal edges of the split tubes forming each tube, and locking edges on the outer periphery of both ends of each tube. The substantially annular joint material has an inner peripheral edge projecting from both end edges in the inner peripheral direction, and an inner peripheral packing material having a constant thickness is provided on the inner peripheral surface of the joint material between the two inner peripheral edges of both ends. The outer circumferences of the engaging edges of the adjacent butting ends of the pipes are pressed against the inner circumference packing material of the joint material.

In addition to the above configuration, two half-split pipes forming each of the pipes are connected via a hinge and a stopper, and the stopper and the stoppers of the two semi-annular members forming the joint material are respectively one-touch type stoppers. In some cases.

(Function) Since the locking edges provided on the outer circumferences of the abutting ends of two adjacent pipes are covered with the inner peripheral edges of both end edges of the joint material, and the joint material is tightened and fixed through the stoppers, Do not disconnect the two pipes. Although each pipe is a half-split pipe,
A packing material is interposed between the butt ends for waterproofing. In addition, at the connecting points of these pipes, since the outer periphery of the engaging edge of the outer periphery of the butting end is in pressure contact with the inner packing material having a constant thickness on the inner circumference of the joint material, water does not enter from the outside. Further, the joint material is an annular body having a constant width, and since an inner peripheral packing material having a constant thickness is provided on the entire inner peripheral surface of the annular body, it is possible to bend adjacent pipes to each other and add them. Even in that case, the outer circumference of each locking edge is pressed against the inner packing material.

Also, if the stopper is a one-touch type, insert the cables into these pipes, and when connecting these pipes from above the cables, stop the pipes with one touch and tighten the joint material that connects many pipes with one touch, Can be fixed.
