(2) arc-shaped steel strand position rotating angle is adopted, compare steel ball position rotating angle, two end points of arc-shaped steel strand are equivalent to two steel balls, and the middle part of arc-shaped steel strand is equivalent to two steel balls to couple together, and can effectively avoid rotational slippage or rotate dumb.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure: 1-display panel, 2-outer tube, 3-holding screw, 4-O shape is enclosed, 5-elastomer joint, 6-electric interfaces, 7-arc-shaped steel strand, 8-circular groove.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, the present embodiment comprises display panel 1, outer tube 2 is provided with below display panel 1, outer tube 2 side is provided with electric interfaces 6, elastomer joint 5 is provided with below outer tube 2, elastomer joint 5 is provided with O shape with the contact position of outer tube 2 and encloses 4, and outer tube 2 is provided with screw hole, and elastomer joint 5 is fixed by holding screw 3 with outer tube 2.Elastomer joint 5 upper surface is provided with circular groove 8, arc-shaped steel strand 7 is provided with in circular groove 8, arc-shaped steel strand 7 is positioned at the Inner arc edge of circular groove 8, the arc radius of arc-shaped steel strand 7 is identical with the radius of a circle of circular groove 8, the arc chord angle of arc-shaped steel strand 7 is 90 degree, the diameter of arc-shaped steel strand 7 is 2mm, and arc-shaped steel strand 7 and circular groove 8 bottom welding are fixed.Be provided with diaphragm in elastomer joint 5, diaphragm can produce elastic deformation.
Add man-hour, embed by the anglec of rotation be applicable to the steel wire bar that diameter is 2mm in circular groove 8, by self-control tool, steel wire bar is aimed at circular groove 8 position after embedding to extrude, steel wire bar is allowed to produce Bending Deformation, form arc-shaped steel strand 7, with laser, arc-shaped steel strand 7 is welded and will be fixed on bottom circular groove 8, make other position of circular groove 8 of embedding arc-shaped steel strand 7 aim at the screw hole of outer tube 2, then screw in holding screw 3 from the screw hole of outer tube 2.
