The invention discloses a longitudinally-folding wing face locking mechanism which comprises a fixed joint, a taper pin, a bush, a driving lever, a spring, a baffle, a rotary joint and a rotary shaft. The taper pin is installed on the fixed joint. A kidney-shaped groove is formed in the side face of the fixed joint. The driving lever and the taper pin are connected through the kidney-shaped groove. The spring is arranged in the kidney-shaped groove. The taper pin, the spring, the driving lever and the fixed joint are assembled through the baffle and screws to form a sliding pair. The axis of the taper pin is parallel to that of the rotary shaft. The bush is embedded in the rotary joint. The axis of the bush and the axis of the taper pin are located in circles with the axis of the rotary shaft as the center, wherein the radii of the circles are equal. When the rotary joint is rotated to the locking position, the axis of the bush and the axis of the taper pin exactly coincide with each other, the taper pin is pressed into the bush under the effect of spring force, and the rotary joint is locked. The longitudinally-folding wing face locking mechanism is exquisite, simple in structure and convenient to detach and install; and the mechanism and the fixed joint are integrally designed and not warped by a protruding structure, and the pneumatic appearance is not damaged.
