Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The present invention is described below with reference to fig. 1-4:

the utility model provides a swing every single move freely movable joint, includes joint objective table 1,

joint casing

2, and 2 casing bottoms in the joint casing are equipped with articulated

seat

3, and 2 inside in the joint casing are equipped with pivot 4, and pivot 4 is connected with articulated seat 3 is articulated. The joint objective table 1 comprises a connecting plate 101, and an upper fixing plate 102 and a lower fixing plate 103 which are symmetrically arranged relative to the connecting plate 101, wherein the upper fixing plate 102, the connecting plate 101 and the lower fixing plate 103 are distributed in a U shape, and the upper fixing plate 102 and the lower fixing plate 103 are fixedly connected with the upper end and the lower end of the rotating shaft 4 respectively by using keys.

The driving shaft 5 is arranged on the joint shell 2, the driving shaft 5 is symmetrically arranged along the rotating shaft 4, the driving bevel gear 6 is arranged on the inner side of the driving shaft 5, the driving wheel 7 is arranged on the outer side of the driving shaft 5, the driven bevel gear 8 is arranged on the rotating shaft 4, the driving bevel gear 6 is meshed with the driven bevel gear 8, the fixing sleeve 9 is arranged on the outer side of the driving shaft 5, the rotating bearing 11 is arranged between the fixing sleeve 9 and the joint shell 2, and the driving shaft 5 is hinged to the fixing sleeve 9 and the rotating bearing 11.

The fixed sleeve 9 is provided with a fixed mounting plate 10 which is convenient for mounting and fixing the movable joint. A bearing 12 is arranged between the fixed sleeve 9 and the driving shaft 5. The driving shaft 5 is provided with a shaft sleeve 13 and a fixing ring 14 for fixing the bearing 12, the shaft sleeve 13 is positioned between the bearing 12 and the driving bevel gear 6, and the fixing ring 14 is positioned between the bearing 12 and the driving wheel 7.

By adopting the technical scheme, when the driving wheels 7 on the two sides of the driven bevel gear 8 rotate in the same direction at the same speed, the two driving bevel gears also rotate in the same direction, so that the two driving bevel gears 6 drive the driven bevel gear 8 to swing along the axis of the driving shaft 5, and the joint objective table 1 can do up-and-down pitching motion only by ensuring that the two driven bevel gears rotate in the same direction.

When the driving wheels 7 on both sides of the driven bevel gear 8 rotate in opposite directions at the same speed, the two driving bevel gears 6 also rotate in opposite directions, so that the two driving bevel gears 6 drive the driven bevel gear 8 to rotate about the center of the rotation shaft 4.
