Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1:
the utility model provides a multistage axle sleeve for tubular product tip, the axle sleeve appearance is the perpendicular superimposed shape of three bushing structure, and every bushing structure center is on same axis, and three bushing structure's external diameter and internal diameter are cascaded gradual reduction from bottom to top, are equipped with screw hole 3 on every bushing structure lateral wall, and every bushing structure's lower edge inboard is equipped with ball 1, and the upper portion of the bushing structure upper portion of uppermost portion seals, and every bushing structure is followed the outside down and is equipped with external screw thread 2.
A bearing 5 is screwed into the external thread 2 at the outer side of the lower edge of each sleeve structure of the shaft sleeve, steel balls of the bearing 5 face outwards, and internal threads are arranged on the inner side of the bearing 5; the threaded holes 3 on the side wall of each sleeve structure of the shaft sleeve are screwed with bolts 6.
At the moment, one end of the pipe or the shaft A is inserted into the shaft sleeve (the pipe or the shaft A can be inserted into the corresponding shaft sleeve according to different thicknesses), and the threaded hole 3 is screwed into the bolt 6, so that the pipe or the shaft A barrel shaft sleeve is fixed by the bolt 6.
The bearing 5 is sleeved outside the shaft sleeve, and if other parts are sleeved outside the bearing 5 at the moment, the pipe or the shaft A can rotate relative to the other parts.
Example 2:
the utility model provides a multistage axle sleeve for tubular product tip, the axle sleeve appearance is the perpendicular superimposed shape of three bushing structure, and every bushing structure center is on same axis, and three bushing structure's external diameter and internal diameter are cascaded gradual reduction from bottom to top, are equipped with screw hole 3 on every bushing structure lateral wall, and every bushing structure's lower edge inboard is equipped with ball 1, and the upper portion of the bushing structure upper portion of uppermost portion seals, and every bushing structure is followed the outside down and is equipped with external screw thread 2.
The lower edge of each sleeve structure of the shaft sleeve is screwed into the support 4 along the external thread 2 on the outer side, one end of the support 4 is annular, the inner side of the ring is provided with an internal thread, and the other side of the ring is provided with a connecting rod.
At this time, one end of the pipe or the shaft A is inserted into the shaft sleeve (the pipe or the shaft A can be inserted into the corresponding shaft sleeve according to different thicknesses), the shaft sleeve and the support 4 are fixed, and the pipe or the shaft A can rotate relative to the shaft sleeve due to the balls 1 arranged in the shaft sleeve.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
