AI Technical Summary

Technical Problem

During cello performance, the anti-slip sleeve at the bottom of the tail column causes the body to rotate smoothly, and the foot may slide due to the reduced anti-slip effect, affecting the performance stability.

Method used

A cello tail pillar supporting foot is designed, including a support rod, insert block, an anti-slip cap and a connecting rod. The adjustable length and rotation of the support rod are achieved through bearings and threaded connections. The anti-slip cap fits with the ground to prevent sliding. The support rod and the connecting rod rotate to drive the body to rotate through the rotation rod.

Benefits of technology

The stable rotation of the piano body during the performance is achieved, preventing the support rod from sliding, and improving the smoothness and stability of the performance.

Abstract

The utility model discloses a violoncello tail column supporting leg which comprises a supporting rod and an inserting block, the inserting block is arranged on the upper side of the outer wall of the supporting rod and used for being inserted into a hole in the tail of a violoncello body to fix the supporting rod, an anti-skid cap is arranged on the lower side of the supporting rod, a connecting rod is arranged at the lower end of the supporting rod, and a rotating rod is arranged at the lower end of the connecting rod. Mounting grooves are formed in the upper end of the rotating rod and the lower end of the connecting rod, bearings are arranged in the two mounting grooves, the two bearing assemblies are connected and fixed through a fixing rod, and the connecting rod can rotate at the upper end of the rotating rod through rotation of the two bearings; when the guitar body rotates, the supporting rod can rotate at the upper end of the rotating rod through the connecting rod to drive the guitar body on the supporting rod to rotate, so that the anti-skid cap does not rotate while the guitar body and the supporting rod rotate, and the anti-skid cap is always attached to the ground to prevent the supporting rod from sliding; therefore, the sliding deviation of the supporting rod caused by the reduction of the contact surface with the ground due to the rotation of the anti-slip cap is avoided.
