Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a branch line guard that protects branch lines that support utility poles, buildings, etc. in an upright state, or prevents contact with the branch lines.

(Prior art) As this type of branch line guard, for example,
- As described in Publication No. 165757, a synthetic resin main body formed into a cylindrical shape, a synthetic resin plug body attached to the upper end of the main body in a closed state,
It is composed of a main body and a connecting member that is inserted into a locking hole provided in each of the plugs fitted to the upper end of the main body to connect the main body and the plug.

This main body is provided with a kerf over the entire length in the longitudinal direction in order to pass the branch line inside the cylinder.

In addition, the plug body has a conical closing part with a through hole formed at the top through which the branch wire is inserted, a cylindrical fitting part that fits on the outer periphery of the upper end of the main body, and a cylindrical fitting part that fits on the inner periphery of the upper end of the main body. It has a cylindrical fitting rib that fits together, and is divided into two along the longitudinal direction corresponding to the longitudinal direction of the main body to form a pair of plug members. Then, the upper end opening of the main body is closed in the joined state of the pair of plug members.

In addition, the connecting member has a locking portion having a diameter larger than the locking hole at the tip of the shaft-shaped insertion portion that is inserted into the locking hole, and the connecting member has a locking portion having a diameter larger than the locking hole. The locking part is press-fitted into the locking hole of the stopper, and is passed through the locking hole to be locked to the inner edge of the locking hole, thereby connecting the main body and the stopper.

When the branch line guard is attached to the branch line, the main body is supported by the stopper that fits on the branch line, and the main body covers and guards the branch line.

(Problem to be solved by the invention) In the conventional branch line guard, the plug body is divided into two parts, so even if the pair of plug members are joined and assembled to the main body, the joint will not work properly. It is easy to have gaps between the parts, and the gaps are visible from the outside and look bad.

In addition, since the main body is supported by the stopper that fits into the branch line, the force applied to the main body acts on the stopper, which tends to cause deformation of the stopper. Therefore, in order to prevent deformation of the plug, it is necessary to increase the wall thickness of the plug as a whole, but this reduces moldability, increases the amount of material used, and increases cost.

Furthermore, the insertion part of the connecting member is inserted into the locking hole to connect the main body and the plug, but since the locking part at the tip of the insertion part has a larger diameter than the locking hole, it is very difficult to insert and work. Bad sex.

The present invention was created in view of these problems, and it hides the gap between the joints of the two-part plug body, improves the strength of the plug body while suppressing cost increases, and also improves the connection. It is an object of the present invention to provide a branch line guard with good connection workability using members.
