Problems solved by technology

[0004] 1. Due to the repeated compression of the spring, the spring is prone to fatigue damage, which affects the service life of the piano bench
[0005] 2. The cushioning effect produced by the compression of the spring belongs to the mechanical cushioning method, and the flexibility of the cushioning is poor
This makes the position of the seating part unstable

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like figure 1 and figure 2 As shown, the embodiment of the present invention discloses a piano stool, which includes a seating portion 10, a base 20, and a buffer mechanism 30. The buffer mechanism 30 has two functions. One is to provide support for the seating portion 10 to Sitting on the seat portion 10 for the pianist, the second is to play a cushioning and shock-absorbing effect on the buttocks and the span of the vertical vibration of the pianist. The buffer mechanism 30 specifically includes a piston rod 31 , a piston 33 , a cylinder 32 and a damping spring 34 . The piston rod 31 is vertically fixed on the bottom of the seating part 10, the cylinder body 32 is vertically arranged on the top of the base 20, the pis...

Abstract

The invention discloses a piano bench which comprises a sitting part, a base and a buffering mechanism arranged between the sitting part and the base and used for supporting and buffering the sitting part. The buffering mechanism comprises a piston rod fixed to the bottom of the sitting part, and a cylinder fixed to the upper portion of the base and provided with an air cavity. A piston is fixed to the free end of the piston rod. The piston is arranged in the air cavity and divides the air cavity into an upper chamber and a lower chamber. A damping spring abutting against the piston is arranged in the lower chamber. The mechanical damping mode and the pneumatic damping mode are combined together through the buffering mechanism, and the damping effect of the piano bench is improved.

Description

technical field [0001] The invention relates to a stool, in particular to a stool for a pianist to sit on. Background technique [0002] Piano players (or learners) need to sit in front of the piano for a long time to play, and the pianists (or learners) are always moving in the body or limbs when playing, for example, the pianist (or learners) are playing During the process, in order to keep the body in sync with the rhythm of the music, the hips and buttocks need to drive the upper body to leave the stool and fall on the stool under the action of gravity, or the seat of the hips and hips and the stool often happens Collision, like this, the seat portion of the stool produces greater impact on the crotch and buttocks, thereby damaging the bones and muscles thereon. In order to prevent this situation from taking place, technicians have designed a kind of piano bench that prevents seat part from producing bigger impact to crotch and buttocks. The piano stool is provided wit...
