The invention discloses a gravity self-adaption elevator for an LED television production line. The gravity self-adaption elevator for the LED television production line comprises two oppositely-arranged longitudinal supports, and a fixed friction board and a carrying platform which are located between the two longitudinal supports. Rolling grooves are formed in the opposite sides of the two longitudinal supports. The upper plane at one end of the carrying platform is connected with an elevating motor through a cable. The elevating motor is located above the carrying platform. The lower plane at the other end of the carrying platform is rotationally installed on a transverse rod. The two ends of the transverse rod are installed in the rolling grooves in a rolling manner. A herringbone friction supporting rod is rotationally installed in the middle of the transverse rod, a flat sliding board fixedly connected to one end of the herringbone friction supporting rod is limited in a rectangular groove in the lower plane of the carrying platform, and a sliding friction board fixedly connected to the other end of the herringbone friction supporting rod makes contact with a fixing friction board. By the adoption of the gravity self-adaption elevator, friction force, resistance and gravity are automatically matched and are adaptive, goods on the carrying platform descend at constant speed, and therefore the gravity self-adaption elevator has the beneficial effects of being capable of saving energy consumption and simple and reliable in structure.
