Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1 to 6, the embodiment discloses a dining car folding mechanism, which includes a front frame 1, a rear frame 2 and a dining plate frame 3, the front frame 1 is connected with the rear frame 2 by a pin, the rear frame 2 can rotate on the front frame 1 around the pin, the dining plate frame 3 is arranged on the front frame 1, a sliding groove 6 is further arranged on the dining plate frame 3, a limiting hole 10 is arranged at the end of the sliding groove 6, a rotating seat 5 is arranged on the rear frame 2, the rotating seat 5 includes a knob pin 11, a return spring 12, a bayonet sleeve 13 and a nut 14, the knob pin 11 sequentially passes through the rotating seat 5, the return spring 12, the bayonet sleeve 13 and the limiting hole 10, and the rear frame 2 is connected with the sliding groove 6 on the dining plate frame 3 through the nut 14.
Still be equipped with dinner plate body 4 on the dinner plate frame 3, the cross-sectional shape of dinner plate body 4 and the cross-sectional shape looks adaptation of dinner plate frame 3, dinner plate body 4 can be held in dinner plate frame 3.
The cross section of the sliding groove 6 is of an arc-shaped structure, the cross section of the rotating seat 5 is of an L-shaped structure, and one side of the rotating seat 5 slightly protrudes, so that the dinner plate frame 3 is kept in a horizontal or vertical state when the dinner plate frame 3 stops rotating.
The diameter of the nut 14 is larger than that of the limiting hole 10, the limiting hole 10 is of a funnel-shaped structure with a large outer part and a small inner part, and the large head end of the T-shaped bayonet sleeve 13 can be inserted into the limiting hole 10.
