Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an improvement of a plastic trough for storing power lines, telephone lines, etc.

(Prior Art) Conventional plastic troughs used for underground wiring or above-ground wiring such as power lines and telephone lines are equipped with partition plates on the inner bottom of the trough body in order to attach partition plates to separate the wiring. Two types of troughs are known: one in which a groove for attaching a partition plate is formed, and the other in which a raised part is provided on the bottom of the trough body and a groove for attaching a partition plate is formed in this raised part, but in the case of the former, the plate on the bottom In addition to having to increase the thickness to form the grooves, the position of the partition plate cannot be changed freely, and in the latter case, the raised part becomes a hindrance when the partition plate is not required. There were also problems such as the space for storing electric wires became narrow. Also, in Utility Model Application Publication No. 52-46297,
There are some models in which longitudinal ridges are provided on the bottom of the trough body and on the back surface of the lid, respectively, and the engaging portions at the top and bottom ends of the partition plate engage with these, but in this case, the ridge positions also vary. Since this does not change, the position of the partition plate cannot be changed freely, and since there is no raised part in the width direction, the long plastic trough body may become distorted unless it is formed very thickly.

(Problems to be solved by the invention) What the invention aims to solve is to eliminate the above-mentioned problems, to make it possible to freely change the position of the partition plate, and to eliminate the need for raised parts when the partition plate is not needed. This was completed with the aim of creating a plastic trough that would not get in the way and would not cause any distortion.

(Means for Solving the Problems) The present invention, which attempts to solve the above-mentioned problems, has ribs for engaging the holding bases arranged at required intervals at opposing positions on the lower inner surfaces of both side plate parts. A trough main body having a U-shaped cross section, a holding base that also serves as a plurality of cable pillows having a concave groove for attaching a partition plate on the upper surface and having engaging portions with the ribs at both ends, and the holding base at the lower end. It consists of a partition plate provided with a concave notch corresponding to the groove of the base, and the holding base is engaged with the rib of the trough body with the engaging parts at both ends, and the bottom of the trough body is attached to the bottom of the trough body in the width direction. A raised portion is formed, and a notch of a partition plate is engaged with the groove of the holding base to form a longitudinally extending compartment partitioned by the partition plate within the trough body. That is.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

Reference numeral 1 denotes a trough body made of reinforced plastic material and having a U-shaped cross section, and reinforcing ribs 3, 3 extending from the bottom to the top are spaced at required intervals on the inner surfaces of the side plate portions 2, 2 of the trough body 1. They are placed facing each other. In this embodiment, one rib 3 is provided at the front and rear ends of the trough body 1, and two ribs 3 are provided near the middle thereof. Reference numerals 4 and 4 designate a holding stand for attaching the partition plate which also serves as a cable pillow and has a concave groove 5 for engaging the partition plate on its upper surface. A section 6 is provided. The engaging portion 6 includes a fit-in engaging portion 6a formed on both left and right ends of the holding base 4 so as to be able to intervene between the two ribs 3, and a rib formed by cutting out both left and right end surfaces of the holding base 4. 2 with the partition engaging portion 6b that engages 3
The two-striped rib 3 has a fitting engagement portion 6a as shown in the figure to engage the rib 3, and the one-striped rib 3 has a cutout engagement portion 6b. It is designed so that it can be engaged. Reference numeral 7 denotes a partition plate that divides the internal space of the trough body 1 in the longitudinal direction and separates the wiring according to the type of electric wire. It is attached by engaging with the groove 5. In addition, 9 is a trough cover made of reinforced plastic material that covers the upper opening of the trough body 1, and 10 and 11 are formed at the front and rear ends of the trough body 1 so that a large number of trough bodies 1 can be connected and used. This is the connecting part.

(Function) In the device constructed in this way, the trough body 1 is buried underground so that its upper end is flush with the ground surface, and the trough body 1 is partitioned with a partition plate 7, and a predetermined portion is placed in each of the trough bodies 1. The cable is stored using the holding stand 4 as a cable pillow, and the upper opening of the trough body 1 is covered with a trough cover 9.
According to the present invention, the holding base 4 for attaching the partition plate 7 has ribs provided so that the engaging parts 6, 6 provided at both left and right ends thereof are opposed to the lower inner surfaces of the side plate parts 2, 2 of the trough body 1. 3 and is detachable, so if the partition plate 7 is not required, the partition part 8 provided at the lower end of the partition plate 7 can be attached to the groove 5 provided in the holding base 4. If the holding table 4 is removed after the partition plate 7 is released and the holding table 4 is removed, the storage space for electric wires, etc. can be enlarged. In addition, since the holding base 4 can be freely replaced, the mounting position of the partition plate 7 can be easily changed according to each application by preparing various holding bases 4 with different intervals of the grooves 5. There is also. Moreover, since the holding base 4 also serves as a cable pillow, the cable does not come into contact with the bottom surface without incorporating a separate cable pillow, and therefore, it can be used in places where rainwater etc. may enter the trough body 1. Also, since the holding base 4 is arranged as a raised part in the width direction at the bottom of the trough body 1 at a required interval,
There is no risk of distortion even if the wall thickness of the trough body 1 is not particularly thick.

(Effects of the invention) As is clear from the above explanation, the present invention has a holding base that also serves as a cable pillow for attaching a partition plate, and an engaging part provided at both ends of the holding base, which is attached to both sides of the trough body. It is removably attached by engaging with the ribs arranged opposite to each other on the lower part of the inner surface, and the partition plates can be attached to this holding base, so the partition plates can be attached at the required intervals when necessary and extend in the longitudinal direction. It is possible to form the required compartment, and since the holding stand prevents the cable from coming into contact with the bottom surface, it is convenient to use in areas where there is no risk of rainwater entering. It has many advantages such as reinforcing the trough body so there is no risk of distortion, and it can solve all the problems of conventional troughs of this type at once.The trough body, holding stand, and partition plate all have a simple structure, so the mold Coupled with the advantage of being inexpensive and easily mass-produced, its practical value is extremely great.
