PURPOSE: A furniture board connecting device is provided to control weakening of connection between a vertical panel and a horizontal panel which is caused by vibration during transfer or use. CONSTITUTION: A furniture board connecting device comprises a fastening ring(10) and a coupling bolt(20). The fastening ring is inserted into an insertion part of a horizontal panel. The coupling bolt is connected to a vertical panel which is orthogonal with the horizontal panel. A head unit(21) of the coupling bolt is inserted into a cam groove(12) which is eccentric to the fastening ring. If the fastening ring is rotated, the head unit is pulled and the horizontal panel and vertical panel are combined. The protrusions(13) are formed around a fixed point in the inner circumference of the cam groove. When a recess unit(23) formed at the lower end of the head unit goes over the protrusions, the rotation of the fastening ring is stopped. A cut-out part(14) is formed right on top of the protrusions on the outer circumference of the fastening ring. |
