Abstract

The utility model provides a folding type support device provided with lockpin, which comprises a seat body, a swing component, a pivot shaft component, a sliding device, a cam, an actuating component and a limiting component. The swing component can be pivoted on the seat body in a forward and backward swinging mode through the pivot shaft component, the sliding device is arranged in the swing component in a sliding mode and comprises a connecting component and a latching component provided with a lockpin, wherein the connecting component is used to assemble a display device. The cam is fixedly arranged on the seat body, the actuating component is arranged on the lateral face of the swing component in a sliding mode, one end of the actuating component is pressed on the cam, the other end is pressed on the limiting component, thereby, when the swing component swings forwards, the cam is pressed on the actuating component and drives the limiting component to slide for buckling the limiting component and the lockpin, and the sliding device is latched on the swing component. When the swing component recovers on the original position, the limiting component is separated from the lockpin due to the tensile force of a resetting elastic component to achieve the purpose of automatic unlocking, and the sliding device can slide on the swing component.
