A kind of wall buried modular building electrical wiring device

Abstract

An electrical wiring device for a wall-buried modular building, comprising four sets of L-shaped boards, a storage board, a combined mounting board, and an extension device, characterized in that: the adjacent two sets of L-shaped boards of the four sets of L-shaped boards The opposite sides of the board are horizontally connected with extension devices to form a rectangular frame, and a first spring rod is movably connected between the four corners of the upper surface of the storage board and the inner wall of the L-shaped board 1, and the combined installation board includes a rectangular transparent shell. and a number of bending through covers that are sleeved in sequence and can be detachably filled in the inner cavity of the rectangular transparent shell, the extension device includes a sleeve and a rack with a through slot near the end, and the two sets of L-shaped rods are pulled in a limited position. And squeeze the rotating rod so that the spline shaft and the spline sleeve cooperate to limit the position, and the snap ring is blocked by the released L-shaped rod. The present invention has the ability to adjust the position of the L-shaped plate through the extension device, and can be installed in the slotted cavity of the wall of different sizes. By combining the rectangular transparent cover and the different number of bent transparent covers, the whole device can be combined into various sizes. , the advantages of easy installation.

Description

technical field [0001] The invention relates to an electrical wiring device, in particular to an electrical wiring device of a modular building buried in walls. Background technique [0002] In home decoration, more and more buildings connect wires to the interior of the wall, which requires the use of wiring devices. The junction box is one of the electrical accessories. The wires are connected and installed inside the junction box to protect the wires. The existing electrical wiring devices have the following problems: 1. During the installation of the junction box and the wall, it is easy to cause the problem that the size of the junction box and the slot reserved in the wall cannot be matched, so the junction box and the wall are increased. The limitation of installation increases the difficulty of using the junction box; 2. It is not convenient to fix the wires after the wires are installed inside the junction box, so the wires are prone to entanglement after installat...

AI Technical Summary

Problems solved by technology

The existing electrical wiring device has the following problems: 1. During the installation process of the junction box and the wall, it is easy to have the problem that the size of the slot reserved in the junction box and the wall does not match, so the junction box and the wall are increased. The limitation of installation increases the difficulty of using the junction box; 2. It is not convenient to fix the wires after the wires are installed inside the junction box, so the wires are prone to entanglement after installation, and it is easy to affect the wires after long-term winding normal use, there is a short circuit

The building electrical wiring device is convenient to adjust the size of the junction box according to the size of the groove on the surface of the wall, which reduces the limitation of the use of the junction box, and is convenient for fixing the wires to avoid short-circuiting after the wires are installed. It is troublesome to install the socket on the top of the device, resulting in labor-intensive and time-consuming

[0003] Therefore there are above-mentioned inconveniences and problems in the known building electrical wiring device
