The present invention proposes a new fixing system for a buried box for fixing an outlet, a switch, or a communication terminal to a buried box buried in a building wall to expose electrical wiring or communication lines.

Building construction is foundation work. It proceeds with facility construction for water supply and electricity supply, wall construction, floor construction, ceiling construction, etc., followed by window installation, exterior wall finishing, handrail construction. Painting work, interior repair work (interior), etc. go through a very complex and specialized step, and in this process, construction efficiency and safety issues are very important. In particular, various electrical facilities are carried out step by step from the initial stage of building construction to the interior and exterior finishing stages.For example, electric piping is carried out by attaching electric piping to the retaining wall reinforcement and formwork during wall and floor construction. After the work is completed, the electrical wiring work is performed through the electrical pipe exposed on the wall. Various electrical facilities such as various electrical facilities, light switches, outlets, communication terminals, and TV outlets are installed in the building through electrical wiring.

Among the finishing construction of such electrical facilities, in particular, the outlet box is a facility frequently used by users residing in buildings, and corresponds to an important device that must be kept safe even if the building is aging. The present invention provides a new fixing method that can increase the value of a building by improving safety and increasing work efficiency when fixing the outlet with the outlet box after connecting the outlet with the wire in the outlet box during electrical wiring work.

Specifically, a coupling pin made of elastic material is used instead of a conventional screw-type metal bolt as a fastening means for connecting to an outlet or a switch on the front side of the buried box or the connection box corresponding to the cover of the buried box. In addition, in order to fix or release the outlet and the embedded box through the coupling pin, the fixing or releasing operation can be performed simply by manual operation of an operator without additional equipment.

To this end, a coupling fixing part for fixing or releasing a coupling pin for fixing an outlet is formed in a buried box embedded in the wall. The coupling fixing part has a through hole in which a fastening protrusion is formed on an inner surface, unlike the screw fastening groove formed in the fixing part of the buried box in the conventional fixing method through screw fastening. It is possible to fix the embedded box and the outlet through a first state in which the coupling pin is engaged with the fastening protrusion of the through hole, and the outlet can be separated from the embedded box through a second state in which the coupling pin does not engage with the fastening protrusion in the through hole. .

The coupling pin that connects with the fastening protrusion and fixes the outlet to the embedded box is made of elastic insulating material, and does not cause physical damage to the wire in the embedded box during the process of fixing the outlet and the embedded box, and the sheath of the wire is peeled off and exposed. There is no risk of electric shock even if you come into contact with the damaged part.

Hereinafter, the technical configuration and operation of the fixing system for a buried box of the present invention will be described in more detail through a preferred embodiment with reference to the drawings.

The number of coupling fixing portions may vary depending on the size of the buried box or the size of the outlet fixed to the buried box, and it is desirable to include at least two coupling fixing portions in the buried box to stably maintain the fixing force. The position of the government may be disposed above and below the inner surface of the buried box or on the left and right sides, respectively.

The coupling fixing part 120 has a through hole 122 formed therein, and includes a pair of fastening protrusions 124 spaced apart from each other so as to face each other on the inner circumferential surface of the through hole. The fastening protrusion is fitted with a coupling pin to be described later to fix a part exposing an electrical terminal or communication terminal such as a buried box and an outlet or switch.
