Abstract: A quick assembly and disassembly structure of a toilet seat base, including a supporting base, base boards, lid bodies, and axial hole portions and connecting portions on the supporting base; each connecting portion is provided with a sliding groove; each base board is slidable back and forth within a corresponding sliding groove and non-movable vertically within the corresponding sliding groove; one end of each lid body is pivotally connected with a corresponding connecting portion; a bottom surface of each lid body is provided with positioning ribs; a top surface of each connecting portion is provided with positioning holes; the positioning holes of each connecting portion are in communication to a corresponding sliding groove. When each lid body is closed, the positioning ribs pass through the positioning holes and fit with the positioning grooves, so that each base board and a corresponding sliding groove are fixed.

Abstract: A novel toilet seat structure, including a supporting base, a toilet seat, fixing blocks and two first buffered-descent modules; the toilet seat includes a child seat that has a child seat body and a first decorative lid; a rear end of the child seat body is provided with a shaft portion including first shaft sleeves and a sliding groove; the first decorative lid is detachably fitted with an opening part of the sliding groove; two ends of the supporting base are provided with second shaft sleeves respectively; a fixing block is embedded inside and being limited from rotating circumferentially in each second shaft sleeve; each first buffered-descent module is embedded inside the shaft portion through the sliding groove, and then passes through a corresponding first shaft sleeve and is then connected to a corresponding fixing block.
