BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a minicab conduit auxiliary material.

[0002]

2. Description of the Related Art Conventional cabs support cables with cable racks, and it is difficult to unify the separation distances of pipes, and it is not easy to insert and connect wires. Moreover, it was difficult to effectively use the road space, and it was not possible to reduce the cost of undergrounding by using ordered roads. In the conventional cab system, it is not possible to expect a large number of pipes in a tight space, which deteriorates the efficiency of construction work and naturally limits the applicable range. Therefore, the present inventor has made it possible to unify the separation distance of the pipes, facilitate the entry and wiring work, enable multiple pipes in a smaller space compared to the conventional cab system, and enable effective use of road space. Already devised. That is,
An end spacer that attaches and supports both ends of each cable introduction tube that has adhesive means applied to the joint end surface of the separator plate that has a plurality of through holes for the introduction tube with a bell mouth, and that has multiple upper and lower surfaces. Of one or more segments provided with semi-reduced holes for the introduction pipe and two segments having a plurality of semi-reduced holes for the introduction pipe corresponding to the above on one of the upper and lower surfaces An intermediate spacer for supporting and supporting by means of an adhering means, and a lid-hanging type mini cab box in which the duct auxiliary material having the above-mentioned composition is accommodated. This is a minicab conduit auxiliary material in which a positioning mechanism such as a dowel is provided at the corresponding portion of the joint surface of the segment.

[0003]

However, in this type of minicab conduit auxiliary material, the composition of the intermediate spacer and the end spacer joint of the auxiliary material of the conduit, as well as the conduit in which the cable introducing pipe is fixedly integrated. It is desired to improve the workability of the auxiliary material assembly and to improve the function of the extension work of the auxiliary material on the site.

[0004]

The present invention has been made in order to solve the above-mentioned conventional problems, and the gist of the present invention is that at least the end spacers of the conventional minicab conduit auxiliary member are used. Frame-shaped double-sided adhesive tape with leg projections at the bottom to improve sliding inside the minicab box, and adhesive means for joining the end faces of the end spacers to the peripheral edge of the separator plate, and guide pins and guide pin holes at the corresponding parts. And a mini-cab conduit auxiliary material characterized in that a retaining protrusion and a fixing protrusion are respectively provided on the inner wall of the introduction pipe through hole with a bell mouth portion and the inner wall of the introduction pipe half-removal portion of the segment. . Next, the present invention will be described in detail with reference to the following embodiments with reference to the drawings.

First, the minicab conduit auxiliary material previously devised by the present inventor will be described with reference to FIGS. First, 1 is an end spacer, which will be described with reference to FIGS. 1A and 2A and 2B. That is, as shown in FIGS. 2A and 2B, through holes 5 for introducing pipes with bell mouth portions 4 are vertically and horizontally arranged in plural rows (three rows) in a rectangular separator plate 2 made of plastic or the like. Adhesive means S such as a double-sided adhesive tape 6 is applied to the entire area of the joint end surface 3 of the plate 2 on the bell mouth portion 4 side. Then, both ends of each of the nine cable introduction pipes 9 are respectively connected to the respective introduction pipe through holes 5.
It can be fitted and supported on. Further, positioning mechanisms P for positioning the joint portion, which are formed with a dowel 7 and a dowel hole 8, are provided at the four corner portions of the joint end surface 3 of the both-ends spacer 1 having the above-described structure. Next, 10 is an intermediate spacer made of plastic or the like.
A, B, and C will be described. That is, the intermediate spacer 10 includes one or more (two) segments 11 having a plurality of (three) introduction hole semi-recessed holes 5a on the upper and lower surfaces 13 and 14, and the above-described one on one of the upper and lower surfaces 15. It is composed of two segments 12 provided with a plurality of corresponding (three) introduction hole half-holes 5a, and is composed as shown in FIG. 3A. The middle portions of the nine cable introduction pipes 9 are joined together. Adhesion is supported by an adhesive means S such as the double-sided adhesive tape 16 provided on the entire surface or a part of the surface.
Further, a positioning mechanism P such as a dowel 17 and a dowel hole 18 is appropriately provided at the corresponding portion of the joint surface of each adjacent segment 11 and 12 in the intermediate spacer 10. In the illustrated embodiment, the case where two intermediate spacers 10 are used is illustrated. Therefore, in the present invention, as described above, the two end portions of each of the plurality of nine cable introduction pipes 9 having the intermediate portions bonded and supported by the two intermediate spacers 10, 10 are fitted and supported by the end spacers 1, respectively. 1A, the conduit auxiliary material M as shown in FIG.
Minicab box 1 with 20 lids as shown in B and C
It is accommodated in 9. Further, the front and rear end faces or the one end faces of the end spacer 1 and the intermediate spacer 10 may have an uneven surface in which, as shown in FIG. 6 and FIG.
And in the present invention, in the field work, the mini cab box 19
The assembly conduit auxiliary material M accommodated therein can be successively added and extended by joining the corresponding end spacers 1 and 1 of each adjacent one. In the present invention, however, in the above-mentioned mini-cab conduit auxiliary material, in order to improve the sliding movement in the mini-cab box 19 at several places below the end spacer 1 and the intermediate spacer 10 (only the end spacer 1 is sufficient). The leg protrusions 22 are provided as appropriate. Further, as shown in FIG. 6, a rectangular frame-shaped double-sided adhesive tape 23 in which the bonding means S for the joining end surface 3 of the end spacer 1 is provided on the periphery of the separator plate 2.
And the guide pin 24 and the guide pin hole 25 at the corresponding portion. Further, as shown in FIGS. 6 and 7, stopper protrusions 21 are provided on the inner wall of the introduction pipe through hole 5 with the bell mouth portion 4 in the end spacer 1, and the segments 11, 12 of the intermediate spacer 10 shown in FIG. The fixed protrusions 26 are provided on the inner walls of the introduction pipe half-removed holes 5a, respectively. In addition, an intermediate spacer 1 formed by combining the segments 11 and 12
The composition of 0 is the side through hole 27 provided on both sides as shown in FIG.
It is performed by screwing a set bolt 28 and a nut 29 which are respectively inserted into The guide pin 24 of the end spacer 1 has a collet chuck structure having a conical protrusion 24a and a slit 24b as shown in FIG. 8 so that it can be firmly fixed by the guide pin hole 25. .

[0006]

EFFECTS OF THE INVENTION In the present invention, since the retainer protrusion and the fixed protrusion are provided on the inner wall of the introduction pipe through hole with the bell mouth and the inner wall of the introduction pipe semi-recessed hole portion of each segment, the spacer and the cable introduction pipe are connected. Fitting and locking can be done easily and surely. Further, since leg projections are provided at least in the lower portion of the end spacer, the assembly pipe auxiliary member slides well in the mini cab box, and the workability can be improved. Further, the connection of the adjacent end spacers in the connection of the conduit auxiliary members can be reliably and firmly and stably performed by the adhesion with the frame-shaped double-sided adhesive tape combined with the fixing function of the guide pin.
