The invention discloses a constant temperature, constant humidity, constant oxygen and constant static air conditioning suit with ambient pressure resistance. The constant temperature, constant humidity, constant oxygen and constant static air conditioning suit with the ambient pressure resistance comprises a coat; both two sides of the coat are fixedly connected with sleeves; the top of each sleeve is fixedly connected with a protective cover; the front surface of the coat is fixedly connected with a protective pad; the inner wall of the coat is fixedly connected with a first sponge layer; the inner wall of the first sponge layer is fixedly connected with a first bending plate; the inner wall of the first bending plate is fixedly connected with a second bending plate; a spring is fixedly connected between the first bending plate and the second bending plate. According to the constant temperature, constant humidity, constant oxygen and constant static air conditioning suit with the ambient pressure resistance, the ambient pressure can be reduced when the air conditioning suit is collided by arranging the protective cover, the protective pad, the first sponge layer, the first bending plate, the second bending plate, the spring, the second sponge layer, a ventilating layer and a third sponge layer, so that the damage of components in the air conditioning suit is prevented, the air conditioning suit is prevented from being replaced because of collision damage, and the economic consumption of a user is reduced.
