Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lid for a wiring pit installed on a floor to house various types of wiring, and particularly to a lid for a wiring pit installed on a floor to house various types of wiring. The present invention relates to a wire passage structure that is attached to a lid body for wire passage.

Conventionally, in offices, factories, etc., gutters (pits) were opened under the floors and used primarily for drainage.

However, in recent years, mechanization has been attempted in offices such as banks, hospitals, schools, factories, etc., and computers and other electronic devices are being used more frequently. The pit is placed in a pit and the pit is closed off with a lid so as not to interfere with work.
-1 Cut out the intangible part from one side to form a notch opening,
There was a wiring structure in which the wiring arranged in the pit was pulled out onto the floor through this notch opening and connected to electronic equipment installed on the floor.

However, since this type of wiring structure has a notch opening in the lid, a large gap is created between the notch opening and the wiring pulled out to the outside, and rats can enter the wiring pit through this gap. problems such as the wiring being eaten away and damaged by the notch opening, the wiring coming from the notch opening coming into contact with the edge of the notch rero causing wear and damage, and the wiring being damaged by dust and foreign matter entering through the notch opening. There was a point.

In addition, a through hole is drilled in the lid body, and a rubber grommet is attached to this through hole to pull out the wiring inside the wiring e-tout to the outside.
A type of wiring structure has been known that solves the above-mentioned problems, but when the wire is passed through the grommet attached to the through hole, one end of the long wire must be connected to the through hole and the grommet. The problem was that the wiring had to be passed through the wiring pit, making it cumbersome to pull out the wiring from inside the wiring pit.

Furthermore, in order to eliminate such defects, an inner cover is provided that closes the notch opening, this inner cover is divided into two, and a through hole is drilled at the partition line of this two-divided inner cover member, so that the wiring pit can be To pull out the wiring, open the front inner cover member, pull out the wire, push the wire into half of the through hole formed in the rear inner cover member, and then open the open front inner cover member. While closing, push the wire pulled out into half of the hole,
A model in which the front inner lid member is fixed with screws has also been developed. However, in order to pull out the wiring from the wiring pit, the front inner lid member is opened and pulled out, so it can be easily pulled out, but in order to open the front inner lid member, the inner lid The parts are attached with screws, so it is necessary to loosen the screws with a tool such as a screwdriver, and I also tightened the screws to close the front inner cover part after pulling out the wiring. There were expectations for the development of a wiring structure that would make it difficult to open and close the inner lid member and would allow wiring to be installed more quickly.

Accordingly, the present invention provides that one side of the lid of the wiring pit is opened in order to route the wiring arranged in the wiring pit provided under the floor to the equipment provided on the floor surface. This wire passage structure of a wiring pit cover body is fitted into an opening in which the wiring pit is fitted, and this wire passage structure includes: - one side has a notch opening that is open on one side; It has a pair of opposing edge frames formed by opening the
The pair of edge frames each have a wire passage structure body in which an inward protruding edge and a locking piece are formed facing each other, and the wire passage structure body slides on an inward solid line of the wire passage structure body to fit into the notch opening. An inner cover is provided with a fitting part that is rotatably fitted to the locking piece of the edge frame in a state in which the notch opening is closed, and the inner cover is closed to the wire passage structure main body. When drilling an arbitrary number of through holes at the center position of the partition line formed between the inner cover and the wire passage structure body, the fitting part of the inner cover fits into the locking part of the wire passage structure body. A wire passage structure of a pit cover body that allows wiring to be easily and quickly drawn out from a wiring pit by providing a wire passage structure of a single lid body that can prevent movement of the inner lid toward the open end side. The purpose is to obtain.

An embodiment of the present invention will be explained below with reference to the drawings. Fig. 1 is a plan view of the wiring et closed with a lid,
