Problems solved by technology

[0003] At present, the manual struts of upright pianos need two hands to operate during the process of lifting and retracting, that is, one hand supports the top cover, and the other hand realizes the operation of the struts, because the top cover has a certain weight. , when operated alone, it is easy to have the danger of improper support and the top cover will fall, the risk factor is high, and it needs to be improved urgently

Abstract

An upright piano top cover strut structure, the invention relates to the technical field of musical instruments; an inner rod is movably inserted inside the outer rod, the lower end of the outer rod and the upper end of the inner rod are both provided with through holes, and the lower end of the outer rod and The upper ends of the inner rods are inserted between two symmetrically arranged rotating pieces, and the two symmetrically arranged rotating pieces are fixed on the fixed seat, and the double-ended screw is inserted into the rotating pieces and the through holes. , and the two ends of the double-ended screw are screwed with nuts respectively; the upper end side wall of the outer rod is provided with a socket, and the side wall of the inner rod is provided with several slots from top to bottom. Insert the inner end of the socket into the socket after passing through the socket. The structure is simple and easy to process, and there is no power consumption of the electric push rod and oil leakage of the hydraulic push rod, which reduces the processing cost, and at the same time facilitates the user to support the top cover, which is convenient for operation, higher in safety and practical. Sex is stronger.
