A modular wall assembly using a solenoid, the modular wall assembly comprising:
- a plurality of main frames fixed to an installation surface, the plurality of main frames being parallel with and separated from each other;
- a supply line mounted on an inside of each of the plurality of main frames, the supply line configured to supply water, a signal, or electricity;
- a withdrawal connector arranged in an exposed manner on an outside of each of the plurality of main frames, the withdrawal connector being connected to the supply line;
- a plurality of installation frames arranged in two dimensions on the plurality of main frames, each of the plurality of installation frames being installed on an edge of a panel or a product;
- a detachable unit mounted on each of the plurality of installation frames, the detachable unit being detachably coupled to each of the plurality of main frames and fixing each of the plurality of installation frames to each of the plurality of main frames;
- and
- a coupling connector mounted on each of the plurality of installation frames, the coupling connector being coupled to the withdrawal connector and thus connected to the supply line and being connected to a line for supplying, to the outside, the water, the signal, or the electricity supplied through the supply line,
- wherein the detachable unit includes:
- a body mounted on each of the plurality of installation frames, the body being inserted into a detaching hole formed in each of the plurality of main frames;
- a solenoid fixed to an inside of the body, the solenoid being operated by a control signal of an operator mounted on each of the plurality of installation frames;
- a slider slidably mounted on the inside of the body, the slider having an attractive force to the solenoid according to an operation of the solenoid;
- a coupling member extending outwards from the slider;
- a plurality of link members hinged to the coupling member and arranged in a radial pattern from a center of the coupling member;
- a plurality of trapping members each having a first side, a second side, and a trap portion, the first side being hinged to an end of each of the plurality of link members, the second side being hinged to the body, the trap portion being trapped in the detaching hole, and the plurality of trapping members being configured to allow the trap portion of each of the plurality of trapping members to be released from the detaching hole by gathering toward the center of the coupling member when the coupling member pulls the plurality of link members according to the operation of the solenoid;
- and
- a spring mounted on the body and configured to produce an elastic force to allow each of the plurality of trapping members to return to an original position, at which the trap portion of each of the plurality of trapping members protrudes outwards and is trapped in the detaching hole.
