The invention belongs to the technical field of aircraft maintenance, and relates to an aero-engine cooling and heat-insulating cabin maintenance covering cap with a quick release function, which comprises a base, a spring lock, a hinge and a covering cap, the spring lock comprises a lock cover, a base, a spring and a lock foot; a lock cavity is formed between the lock cover and the base, the two sets of lock feet are located at the two ends of the lock cavity respectively, and the spring is connected between the two sets of lock feet. A long-strip-shaped guide groove is formed in the base, an L-shaped lock hook is arranged at the bottom of the lock foot, and the lock hook extends out of the guide groove. When the covering cap is installed and maintained, the lock foot is pressed inwards, the lock hook below the lock foot moves towards the middle of the lock cavity along the guide groove, the spring is compressed in the process, and when the tail end of the lock hook reaches the edge position of the lock hole, the covering cap is pressed downwards, the lock hook is inserted into the lock hole, then the lock foot is loosened, and locking of the covering cap is achieved. No tool is needed in the opening and mounting process, and damage to the covering cap or the base body possibly caused by mounting and opening through the tool is avoided.
