[0003] However, due to the frequent use of the piano, the number of times the piano cover is opened will also increase. The existing piano keyboard cover slow down device adopts a gas spring or a rotary damper, wherein the gas spring has a large structural size and is not beautiful, and it is placed on the piano cover. When it is closed, it is not easy to limit and fix the piano cover, which will cause the piano cover to shift when it moves, and it is not easy to support the opened piano cover, which will cause the piano cover to be closed by external force, resulting in damage to the piano and hands. all hurt

Abstract
The invention discloses a buffer device for opening and closing a piano cover. The buffer device comprises supporting legs, a supporting buffer mechanism and a limiting mechanism. The supporting buffer mechanism is arranged at the upper end of the piano cover, so that when the piano cover is closed, a sliding shaft moves relative to the upper end of a sliding groove, a first swing rod and a second swing rod are mutually folded, meanwhile, the second swing rod can push a sliding block to move towards the front end to drive a jacking mechanism to be linked, so that a buffer rod moves towards the upper end to absorb the impact force of the closed piano cover, and the advantage that the piano cover can be closed and buffered is achieved; and a limiting mechanism is arranged at the upper end of a transverse plate, when a piano cover is closed, a pressing rod can be pressed to absorb impact force, meanwhile, the pressing rod drives a pressing head to move towards the lower end, a pushing mechanism pushes a pressing mechanism to swing towards the left end, a second top bead abuts against the left end of the piano cover, and the advantage of preventing the piano cover from moving and deviating is realized.
Description
technical field [0001] The invention relates to the related field of piano lid switches, in particular to a buffer device for piano lid switches. Background technique [0002] The piano is a keyboard instrument in Western classical music. It has the reputation of the king of musical instruments. It consists of eighty-eight keys and a metal string soundboard. The role of dust. [0003] However, due to the frequent use of the piano, the number of times the piano cover is opened will also increase. The existing piano keyboard cover slow down device adopts a gas spring or a rotary damper, wherein the gas spring has a large structural size and is not beautiful, and it is placed on the piano cover. When it is closed, it is not easy to limit and fix the piano cover, which will cause the piano cover to shift when it moves, and it is not easy to support the opened piano cover, which will cause the piano cover to be closed by external force, resulting in damage to the piano and hands...
