Abstract
A butt-joining and engaging structure that allows to a pair of columns to be connected. The butt-joining and engaging structure has a seat body with a first connecting portion and a through hole, a stop part extends from an inner wall of the through hole toward the center of the through hole, a connecting member has a pair of ends defining a plug-in portion and a second connecting portion, and a position limiting part protrudes from the abutment surface of the connecting member. The first connecting portion is adapted to be affixed to one of the pair of columns. The second connecting portion is adapted to be secured to an end of the other column.
Claims9
A butt-joining and engaging structure for connecting a pair of columns, the butt-joining and engaging structure comprising:
- a seat body having a first connecting portion, said seat body having a through hole formed in said first connecting portion, said first connecting portion adapted to be affixed to one end of one of the pair of columns, said seat body having a plate body affixed to said first connecting portion and adapted to cover an end face of the one of said pair of columns;
- a stop part extending from an inner wall of the through hole toward a center of the through hole;
- a connecting member having a pair of ends respectively defining a plug-in portion and a second connecting portion, the plug-in portion conforming to a shape of the through hole so as to form a rod body structure, the plug-in portion having an abutment surface and being selectively insertable into the through hole, the second connecting portion adapted to be secured to one end of the other of the pair of columns;
- and
- a position limiting part protruding from the abutment surface of said connecting member, a cross section of the plug-in portion and the position limiting part corresponding to a shape of an accommodating space defined by the through hole and said stop part for the plug-in portion of said connecting member, wherein, said position limiting part is extendable beyond said stop part, wherein when said connecting member is rotatable relative to said seat body by a predetermined angle θ, the abutment surface of said connecting member abuts against a side end of said stop part and said position limiting part is aligned with said stop part in an overlapped clamping state such that said stop part blocks said position limiting part so as to lock said connecting member and said seat body to firmly connect the pair of columns, wherein a ring wall protrudes between the plug-in portion of said connecting member and said second connecting portion, the through hole of said seat body having an enlarged groove corresponding to a shape of the ring wall, the ring wall being selectively insertable into the enlarged groove of the through hole such that said connecting member can rotate relative to said seat body.
