Different assembly modeling can be completed by adjusting different angles of the rotating shaft and matching various plates.

Concrete installation method of clamping plate type connecting piece in embodiment

The modeling of the furniture is determined, and in the process of installing the two plates, a rotating shaft with a thickness adjusting gasket or a rotating shaft without the thickness adjusting gasket is selected according to the actual thickness of the plates. The first side plate 11 and the second side plate 12 are attached to the inner side and the outer side of the plate, the inner holes and the outer holes of the two side plates are kept horizontal, the rotating shaft and the two side plates are combined and fixed in a mode that the pair of holes 1312 of the upper rotating body of the rotating shaft 13 and the holes of the side plates are kept horizontal, finally, the screw 14 extends into the outer hole 111 of the first side plate 11, the screw cap 141 can be clamped outside the inner hole 112 of the first side plate, so that the screw cap can be retained in the accommodating cavity of the outer hole 111, the screw rod sequentially penetrates through the inner hole 112 of the first side plate, the hole 1312 of the upper rotating body, the inner hole 122 of the second side plate and the nut 123 arranged in the second side plate, the contact length of the screw thread 143 and the nut 123 can be determined by the thickness of the plate, the soft rubber gasket 113 arranged in the first side plate and the soft rubber gasket 124 arranged. The connection mode of the following pair of side plates and the plate is the same as that described above, and the description is omitted. After the upper and lower side plates are connected with the plate, multi-angle rotation is achieved by the action between the thread groove 1313 of the upper rotator 131 and the thread 1323 of the lower rotator 132 of the rotating shaft until the required angle is achieved. When only two panels are rotated, the angle is not controlled very accurately by man, but when the connection of a series of panels is connected, the angle can be determined accurately naturally through the integral assembly.
