Abstract

A design for controlling hovering of a hinge eccentric shaft on torsion equipment such as a folding screen and the like is formed by connecting a left spreading wing 1 of a strip-shaped conjoined body, a plurality of 2-1 right spreading wings 2, 2-2 right spreading wings 3, 2-3 right spreading wings 4 and 2-4 right spreading wings 5 which are adjacently crossed and staggered in a split mode with each other and each shaft sleeve in the middle position of the two wings. The A1 left wing-spreading shaft sleeve 6 and the B1 right wing-spreading shaft sleeve 7 are oppositely crossed and adjacent, are coaxial and concentric, and pass through the C1 shaft 8 in the middle. The axis is D1 and 9, which are a group. The axes of the first group and the second group are respectively different and slightly different, namely the A2 left wing-stretching shaft sleeve 10 and the B2 right wing-stretching shaft sleeve 11 are oppositely crossed and adjacent, are coaxial and concentric, and pass through the C2 shaft 12 in the middle. The axis is D2 axis 13. Because the respective axes of the first group and the second group are different, damping friction is generated, so that the left wing and the right wing mutually pull the elbow to balance, and the purpose of hovering at any time is achieved. The invention has the characteristics of simple and stable structure, uncomplicated manufacturing process, controllable torsion damping, low cost, practicality and durability.
