Abstract

The invention relates to a lifting referee chair. Frisbee devices are arranged in armrest plates on the two sides of an upper seat respectively, a rotary shaft is connected between the two frisbee devices, a groove is formed in the armrest plate on one side of the upper seat, a push rod is inserted in the groove, and a fixed pulley is arranged at the tail end of the interior of the groove; one end of a first steel wire is connected to the push rod, and the other end of the steel wire bypasses the fixed pulley to be wound around a small disc of the frisbee device; a second pulley block is arranged on the bottom of the outer wall of each of the armrest plates on the two sides of the upper seat, a first pulley block and a hook are arranged on the top of the outer wall of each of armrest plates on the two sides of a base, one end of each second steel wire is fixed to the corresponding hook, and the other end of each second steel wire bypasses one pulley of the corresponding second pulley block and one pulley of the corresponding first pulley block in sequence in a circulating mode to be finally wound around a large disc of the frisbee device. The lifting referee chair has the advantages that the pulley blocks are effectively utilized so that lifting can be achieved effortlessly and quickly, the structure is simple, service life is long, production cost is low, maintenance is not needed, safety and reliability are high, and storage and dust prevention can be achieved conveniently.
