Description

[Detailed description of the invention] [Field of industrial application] The present invention fixes a branch line protection guard that covers and protects the branch line stretched to keep the utility pole in a vertically erected state, and in particular, to improve rain protection. and a cap that fits over the end of the guard.

[Prior art] Conventionally, as for the cap of the branch line protection guard divided into two parts, for example,
There is a "branch line guard" number 120156. In this method, a plug body that closes the end opening of the guard body, which is provided with a groove over its entire length, is formed into a conical closing part with a through hole bored at the top, and a plug is formed on the outer periphery of the bottom of the closing part. A cylindrical fitting part is formed to fit into the outer periphery of the end of the guard body. The guard body is provided with a pair of engagement holes at positions sandwiching the groove therebetween, and the plug body is divided into two in the longitudinal direction of the guard body. Then, an arc-shaped fitting rib is provided inside the fitting portion along the inner circumference of the end of the guard body, and the fitting portion of one of the divided plugs and the fitting portion of the other plug are provided with the guard body. A locking part is provided with insertion holes corresponding to the pair of engagement holes, and each insertion hole and an engagement protrusion inserted into each engagement hole are engaged with the guard body using stops provided at both ends. Formed so that it is stopped.

As a result, the two-part stopper is firmly connected to the opening at the end of the guard body to close the opening.

[Problem to be solved by the invention] However, although this prior art discloses a strong coupling means between the stopper and the end opening of the guard body, the sealing structure inside the cover body is actually extremely incomplete. It is. That is, although FIG. 4 shows a structure in which something similar to an engaging tongue is protruded from each end line of the divided stopper, the terminal end of this engaging tongue is formed horizontally in cross section. In addition, when each plug is fitted to the outer periphery of the end of the guard body, it contacts only a small portion of the circumferential wall of the arc-shaped through hole of the guard body, and does not cover the entire surface of the end of the circumferential wall. . For this reason, the terminal ends of the opposing engaging tongues cannot fulfill the function of holding and holding the branch wire inserted into the through hole, and if a gap occurs in the connecting part of the stopper due to impact, the branch wire will There is a problem that it may come off and the protection cannot be provided.

In addition, since the peripheral wall of the through hole has a smooth surface, when the diameter of the branch wire inserted through the hole is smaller than that of the through hole, there is a problem that a gap is formed between the through hole and the branch wire, allowing rainwater to enter. be.

[Means for Solving the Problems] Therefore, the present invention is a cap that fits onto the end of a guard body formed by cutting a long cylindrical tube at one longitudinal side so that it can expand. A pair of cap halves are formed by vertically symmetrically dividing a conical lid extending from the upper end of a short cylindrical part to be fitted into the end of the cap, and a branch wire insertion hole provided in the center of the lid. A fin piece divided by a cut is provided around the branch line insertion hole, and a branch line insertion hole is provided in the lid body of each cap half from the outer end of one side edge to the branch line insertion hole. It is formed by protruding an engaging tongue that is wide at the side, and an arc-shaped stopper portion that matches the branch line insertion hole is provided at the terminal end of the engaging tongue.

[Function] When storing the branch line in the guard main body, the branch line guided by the edge of the engaging tongue of one half of the cap enters the center of the cap and fits into the branch line insertion hole, and at the same time, the branch line is inserted into the other cap half. The branch line is securely held by the arc-shaped stopper at the end of the engagement tongue of the half body and the arc-shaped stopper of the engagement tongue of the one cap half, so that the branch line is inserted between the ends of the cap halves. is firmly held in the branch line insertion hole without being pulled out.

The fin pieces, which are divided by cuts and provided around the branch line insertion hole, bend and stand up along the outer peripheral surface of the branch line, and close the space between the branch line insertion hole and the fin piece.

[Examples] Examples of the present invention will be described below with reference to the drawings.
In the figure, 1 is a guard body made of a long synthetic resin tube with a cylindrical inner diameter that can accommodate a connecting fitting connecting an anchor bolt B and a branch line C. It is formed so that it can be opened. At the end of the guard main body 1, engaging holes 3, 3 are provided opposite to each other at positions perpendicular to the cutout 2.

Reference numeral 4 denotes a cap attached to the end of the guard body 1, which has a conical lid 6 extending from the upper end of the short cylindrical portion 5 and a branch wire insertion hole 7 in the center of the lid 6. It consists of a pair of cap halves 4a and 4b that are vertically divided symmetrically at the center of the insertion hole 7, and each cap half 4a and 4b has a short cylindrical portion 5.
A locking pawl 8 having a horizontal upper surface and an inclined lower surface is protrudingly provided at the center of the inner surface. Further, the lid body 6 is provided with an engaging tongue piece 9 protruding from the lower edge of the portion extending from one outer edge of the side edge to the branch line insertion hole 7, the width of which gradually increases as it reaches the branch line insertion hole 7. The terminal end of the engaging tongue piece 9 forms an arc-shaped stopper portion 9' that matches the branch line insertion hole 7. In the embodiment, the inner diameter of the short cylindrical portion 5 is formed to match the outer diameter of the guard body 1, and an inner wall 10 that is in contact with the inner surface of the guard body 1 is vertically provided inside the short cylindrical portion 5. .
This inner wall 10 has a notch formed in its center so that the locking pawl 9 is exposed. Moreover, a fin piece 12 divided by a notch 11 is provided around the branch line insertion hole 7 .

The cap halves 4a and 4b formed in this way are combined into a set with each cap half 4a and 4b facing each other.
Align one side end of the guard body 1 with the cutout 2, insert the end of the guard body 1 between the short cylindrical part 5 and the inner wall 10, and push the locking claw 8 into the guard body 1. By fitting into the matching hole 3, the cap 4 is firmly fixed to the guard body 1.

Figure 3 shows the state of use, and shows utility pole A.
If the incision 2 is widened and the guard body 1 is passed through the branch line C which is stretched in an inclined manner between the anchor bolt B and the anchor bolt B whose one end is buried in the ground, the cap 4 is formed.
Then, the branch line C is the cap half 4a with one side expanded,
4b, go between the two caps, and remove one half of the cap 4.
The cap 4 is guided by the edge of the engaging tongue piece 9 of a.
At the same time, the terminal end of the engaging tongue piece 9 of the other cap half 4b and the stopper part 9' of the engaging tongue piece 9 of the other cap half body 4a enter into the center of the branch line insertion hole 7. As a result, the branch wire C is securely held in the branch wire insertion hole 7 without being pulled out from between the cap halves 4a and 4b.

Then, when the opening of the cutout 2 of the guard body 1 is stopped, the branch line C is held in the branch line insertion hole 7 at the center of the cap 4 at the end of the guard body 1, and is positioned at the center within the guard body 1. be able to. In addition, in the cap 4 in which the branch line C is held in the branch line insertion hole 7 in the central part, the engaging tongue pieces 9 of each cap half are overlapped with the lower surface of the lid 6 of the other cap half,
Further, the fin piece 12 bends and stands up along the outer circumferential surface of the branch line C, and closes the space between the branch line insertion hole 9 and the fin piece 12, thereby making it possible to improve rain protection.

[Effects of the invention] As described above, the cap of the branch line protection guard of the invention is formed by forming a pair of cap halves, which are made by vertically dividing the short tube part and the lid body symmetrically and facing each other. , the short cylindrical part was inserted into the guard body, the locking claws protruding from the short cylindrical part were fitted into the engagement holes provided in the guard body to ensure secure installation, and the incision was expanded to allow the branch wire to pass through. At this time, the branch line was guided by the edge of the engaging tongue protruding from the lid piece of one half of the cap, and it fit into the branch line insertion hole provided in the center of the lid body. In this state, the force to hold the branch line in the branch line insertion hole is strengthened by the stopper part at the end of the engaging tongue of each cap body, and the branch line can be firmly maintained in the center of the protective guard.
Furthermore, these engaging tongues close the space between the lid bodies, and the fin pieces, which are divided by cuts and placed around the branch line insertion hole, also close the space between the branch line insertion holes, improving the effect of keeping out rain. There are some advantages.
