Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a guard that covers and protects a branch line stretched to maintain a utility pole in a vertically erected state.

[Prior Art] A first prior art technique in which a cap is attached to the expandable guard body by providing an incision in the longitudinal direction of the long tube in this type of branch line protection guard is, for example, Utility Model Application Publication No. 47-34093. There is a ``branch line guard'' of the issue.
The cap is formed from a pair of half members that are almost symmetrical, and each half member is joined to be openable and closable by an integrally molded hinge on a part of the split surface, and has male and female fittings on at least one opposing contact surface. The pipe has a plurality of protrusions on the circumferential surface thereof, and a through hole is formed in the pipe to fit the protrusions of the cap when the cap is fitted on the pipe.

In addition, as the second conventional technology, Utility Model Application No. 57-165757
There is a ``branch line cover'' of the issue. This is a cap of 2
The two halves are combined to form a lid body, which has a cylindrical part at the bottom, a conical part at the top, and a through hole through which the branch wire is inserted in the center of the upper end of the conical part. A cylindrical edge is made to hang down from the lower end of the conical part, and a groove is formed between the cylindrical edge and the above-mentioned cylindrical part to insert and lock the upper end of the cover body.

[Problem to be solved by the invention] The first conventional technique is that when a cap is fitted to the upper end of a pipe, a protrusion provided on the outer peripheral surface of each half member is inserted into a through hole drilled in the upper end of the pipe on the inner peripheral side of the pipe. Just insert it from there. As a result, the protrusions are not properly fixed, which causes them to wobble and deteriorate due to shocks and vibrations.In addition, after many years of use, rainwater can enter through the holes in the pipes and corrode the branch wires inside the pipes. . In addition, since each half member is integrally joined by a hinge, both half members must be attached or removed from the upper end of the pipe, so that it is difficult to carry out work when inspecting the inside of the pipe, for example. There is also the problem that it is time consuming.

In addition, in the second prior art, the groove of the short cylindrical part made of a double wall is fitted into the upper end of the cover body to attach the lid, but at this time, in order to engage the cover body and the lid, for example, Through-holes are opened at positions corresponding to the above-mentioned shapes, and fasteners having a flange portion and an enlarged locking portion are fitted into both holes and fixed. For this reason, there are problems in that fixing with the stopper is time-consuming and requires a separate stopper member.

Furthermore, in both the first conventional technology and the second conventional technology, when attaching the lid body to the upper end of the cover body, a recess (receiving hole) and a protrusion (locking protrusion) provided in each half member (half part) are used. They simply engage by fitting into each other. For this reason, there is a problem in that the half members are easily disengaged when subjected to impact, etc., and rainwater or the like can enter through the slight separation point, causing corrosion of the branch wires of the cover body.

[Problems to be solved by the invention] For this reason, the present invention provides a branch line protection guard in which a cap is attached to the end of the guard main body, which is formed by cutting a cylindrical long pipe at one side in the longitudinal direction so as to be expandable.
The end of the guard body is provided with engaging holes facing each other at positions perpendicular to the incision, and the cap has a conical lid body at the upper end of a short cylindrical part made of double walls that holds the end of the guard body. is extended, and a branch line holding hole is further formed in the center of the lid body, and the lid body is vertically divided symmetrically to form a pair of cap halves. A locking claw is formed in a protruding manner in the center, and a notch is formed in the center portion of the inner wall to expose the locking claw, and the lid body has a portion extending from one outer end of the side edge to the branch line holding hole. At the lower edge thereof, an engaging tongue piece whose width gradually becomes wider on the side of the branch line holding hole is protruded, and when the cap halves are assembled into a pair, the end of the guard body is inserted between the double walls of the short cylindrical part. The cap is inserted and the cap is pushed in, and the locking pawl is fitted into the engagement hole formed in the guard body.

[Operation] Place the cap halves in a pair of left and right opposite positions, align one end of each cap half with the incision, and insert the end of the guard body between the outer wall and inner wall of the short cylindrical portion. If the cap is pushed in as it is, the locking pawl provided on the inner wall of the cap half will fit into the engagement hole of the guard body, and the cap will be firmly attached to the end of the guard body with one touch.

Further, since a notch is provided in the center of the inner wall, the locking pawl provided on the outer wall can be easily seen at a glance, and alignment with the engagement hole of the guard body is facilitated.

The cap can be installed with the cap halves firmly fixed, and the gap between the side edges of the lid body of both cap halves is closed by overlapping engagement tongues, preventing rainwater from entering. I can do it.

[Example] An example 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 cylindrical synthetic resin tube with an inner diameter capable of accommodating a connecting fitting connecting an anchor bolt B and a branch line C. The guard body is made expandable by cutting a straight line on one side in the longitudinal direction. , and engagement holes 3, 3 are provided oppositely at positions perpendicular to the cutout 2 at the end.

4 is a cap attached to the end of the guard main body 1, and a short cylindrical portion 7 consisting of a double wall of an outer wall 5 and an inner wall 6 that clamps the end of the guard main body 1 from both inside and outside.
A pair of cap halves are formed by extending a conical lid 8 at the upper end and having a branch line holding hole 9 in the center of the lid 8, which is vertically divided symmetrically at the center of the branch line holding hole 9. It is formed from bodies 4a and ab.
Moreover, 6a is a notch formed in the center portion of the inner wall 6. Each of the cap halves 4a, 4b has a locking pawl 10 projecting from the center inside the outer wall 5, and a notch 6a is provided at the center of the inner wall 6 so that the locking pawl 10 is exposed. Further, the lid body 8 is provided with an engaging tongue piece 11 protruding from the lower edge of the portion extending from one outer end of the side edge to the branch line holding hole 9, the width of which gradually increases on the side of the branch line holding hole 9. Further, the branch line holding hole 9 is provided with a flexible fin piece 12 which is divided into a large number of parts.

Cap halves 4a and 4b formed in this way
are arranged in pairs on the left and right, and each cap half 4a,
By aligning one end of the guard body 4b with the cutout 2, inserting the end of the guard body 1 between the outer wall 5 and inner wall 6 of the short cylindrical portion 7, and pushing it in, the cap halves 4a and 4b will be removed. The locking pawl 10 provided on the inner wall 6 is fitted into the engagement hole 3 of the guard body 1, and the cap 4 can be firmly fixed to the end of the guard body 1 with one touch. At this time, since the locking pawl 10 provided on the outer wall 5 is exposed through the notch 6a provided in the center portion of the inner wall 6, alignment with the engagement hole 3 of the guard body 1 can be easily performed.

Next, the usage will be explained. As shown in Fig. 4, the cutout 2 is widened and the guard body 1 is passed through the branch line C which is stretched in an inclined manner between the utility pole A and the anchor bolt B whose one end is buried in the ground. As the cutout 2 of the guard body 1 expands, the cap 4 also expands one side of the cap halves 4a, 4b, so that the branch line C fits into the cap 4. At this time, since the engaging tongue piece 11 is provided on one of the cap halves 4a, the branch line C enters the branch line holding hole 9 while being guided along the edge of this engaging tongue piece to the center of the cap 4. The branch line C can be easily fitted and held.

If the opening of the incision 2 is stopped with the branch line C fitted into the branch line holding hole 9, the cap halves 4a and 4b will no longer expand and the branch line C will be held at the center position of the protective guard. Furthermore, the gap between the side ends of the lid body 8 of the cap halves 4a and 4b is closed by the overlapping engagement tongue piece 11, so that the gap is eliminated, and the gap between the side ends of the lid body 8 of the cap halves 4a and 4b is closed, and the gap between the side ends of the lid body 8 of the cap halves 4a and 4b is closed. Hole 9
Since the fin piece 12 bends and closes the space between the two, the effect of keeping out the rain can be improved.

[Effects of the invention] As described above, in the branch line protection guard of the invention, the cap to be attached to the end of the guard body is formed by a pair of cap halves symmetrically aligned with the cutout of the guard body, and each A short cylindrical part to be inserted into the end of the guard body is formed as a double wall in the cap half, and a locking pawl is provided protruding from the short cylindrical part so that the guard body is inserted between the double walls of the short cylindrical part. By pinching the end of the cap and pushing it in, the locking pawl will fit into the engagement hole provided in the guard body, and the cap can be firmly fixed to the guard body with one touch. Not only does this improve durability, but it also prevents the branch wire from shifting when passing it through, and the cap from falling off during use. In this case, since the notch is provided in the center of the inner wall, the locking pawl provided on the outer wall can be easily seen and can be easily fitted into the engagement hole of the guard body. Further, the effect of keeping out rain can be further enhanced by the engagement tongue pieces provided on the side edges of the lid body of each cap half and the fin pieces provided in the branch line holding holes.
