Patent ID: 8911034

Claim:
A housing having quick-dismounting structure, comprising: a base plate, having a retaining portion, wherein the retaining portion has a first side substantially perpendicular to the base plate and a bottom side extended from a bottom end of the first side substantially parallel to the base plate; a covering plate, having one side corresponding to the retaining portion of the base plate and formed with a switch recess thereon; and a switch module, rotatably dispose in the switch recess, said switch module includes: a holding portion exposed outside the switch recess, having a stopping member extended from an edge thereof adjacent to the base plate, the stopping member substantially parallel to the first side of the retaining portion, wherein the stopping member has a pushing block protruded toward and approximated to the retaining portion; a hook piece protrudedly formed and integrally extended from an inner side of the holding portion toward the base plate; and an elastic element, assembled on the holding portion for providing a recovering force for the holding portion and the hook piece; wherein the hook piece has an oblique surface slanted to the first side of the retaining portion, a hooking end-portion concaved from a top end of the oblique surface faced the retaining portion, and a recess defined between the hooking end-portion and the stopping portion for selectively restricting the retaining portion therein; wherein the pushing block and the hooking end-portion are located at two sides of the retaining portion; wherein when the holding portion is moved, the hook piece shifts accordingly and the hooking end-portion is selectably hooked the retaining portion which then lock or disengage the covering plate; wherein when a bottom end of the holding portion is rotated outside from the switch recess for opening the covering plate, the pushing block of the stopping member exerts an action force on the retaining portion of the base plate, and the retaining portion of the base plate therefore exerts a reaction force on the holding portion.
