Abstract

A stepless type rotation shaft positioning mechanism includes a rotation shaft having a peripheral surface integrally provided with a protrusion plate part; a wear-resistant sheet provided at one side of a first plate surface of the protrusion plate part; a plurality of plate-shaped springs stacked at one side of a second plate surface of the protrusion plate part; an outer casing provided with an accommodating room for allowing the rotation shaft to pass therethrough, fixing the wear-resistant sheet, and accommodating the protrusion plate part and the plate-shaped springs; and an elastic piece pressing plate for pressing the plate-shaped springs at the side opposite to the side of the second plate surface. The elastic piece pressing plate is screwed to the outer casing such that a depth of screwing changes a pressing force of the plate-shaped springs applied to the second plate surface. The first plate surface abuts tightly against the wear-resistant sheet. Accordingly, the rotation shaft is rotatable for angle adjustment through rotation and upon completion of the angle adjustment when the rotation force disappears, the protrusion plate part can be instantly locked by the axial heavy pressing force of the plate-shaped springs in combination with the fixed wear-resistant sheet, such that the rotation shaft can be immediately positioned without steps.

Description

Stepless shaft positioning mechanism

The invention provides a technical field of a rotating shaft, in particular to provide a stepless rotating shaft positioning mechanism, wherein the rotating shaft is provided with a protruding disc portion, and the two sides of the protruding disc portion are respectively a wear-resistant piece and a disc-shaped spring, and are wear-resistant. The sheet is fixed, and the disc spring is a pressure-adjusting disc portion and a wear-resistant sheet with adjustable weight pressure, so that the shaft-free positioner can be reached.

According to the current practice, there are several ways to position the shaft, which are ratchet type shaft positioning, bolt type shaft positioning, and torsion spring type shaft positioning. However, the ratchet type shaft positioning has a paragraph sense, and its ratchet and The ratchet bite has a large gap. When it is shaken, the gap will be amplified. The gap is larger and difficult to use, or it is easy to damage. Therefore, the ratchet method still has quite a few disadvantages, and the plug type has more problems, except that it must have holes. The problem of position alignment, the problem of gaps in the plug pins, etc., and the torsion spring type of the shaft used in the notebook computer, because of the limited force that the torsion spring can withstand, is not stable and firm, so it is used for heavy loads. The environmental damage rate is extremely high, so it has gradually been eliminated.
