Revolving shaft structure

Technical Field

The utility model relates to a revolving axle structure particularly, indicates to the cylinder with air supply drive, and its inside revolving axle cooperation gyration cover is with steel ball and locating lever to correspond the gyration body inner wall and form limited actuation, be used for improving the purpose of friction consume.

Background

A conventional revolving shaft is structurally characterized in that the periphery of the surface of the revolving shaft is engraved with an external thread for receiving the inside of the body of the revolving shaft, and is engraved with an internal thread matching with the external thread.

When the revolving shaft is matched with a sleeving part and arranged in the body, the sleeving part indirectly limits the axial direction of the revolving shaft through the mutual meshing of the internal thread and the external thread, and when the revolving shaft is driven by a dynamic source, the internal thread of the revolving shaft is limited by the external thread in the body and the sleeving part, so that the revolving shaft is converted into linear motion.

However, the conventional rotating shaft has low transmission efficiency due to the friction between the internal thread and the external thread, and the service life of the rotating shaft is not long due to wear caused by the friction.

Although the industry has made subsequent improvements to the above-mentioned drawbacks, the main solution is to use steel balls disposed between the internal threads and the external threads to reduce the friction area between the main body and the rotating shaft, and to add a lubricant to help the steel balls to run smoothly, thereby improving the wear-out situation.

SUMMERY OF THE UTILITY MODEL

In view of the above circumstances and problems, the inventor has accumulated the development experience of related industries for many years, and has diligently studied and made a pivot structure more suitable for the needs of modern users by integrating the above conventional structure.

The utility model discloses revolving axle structure, its gyration body top has outside can supplying the glide machanism to inlay a recess of putting usefulness, the inside of this gyration body still is provided with one and wears the groove and leads to a perforation of this wearing groove, and the outer circumference is carved with a gyration axle and the outside that the gyration caulking groove is provided with spacing hole and a gyration cover of caulking hole, wherein should inlay the downthehole steel ball that is equipped with, establish the back with this gyration cover of the inboard cooperation of this gyration cover, further set up in this wearing groove, make the steel ball top support the inner wall of this gyration caulking groove and this wearing groove, and cooperate a locating lever to lead to this spacing downthehole through this perforation, make this revolving axle can be limited by this steel ball and rotate and actuate.

The second objective of the revolving axle structure of the present invention is that the sliding mechanism is composed of a sliding seat and a sliding rail, the sliding seat is embedded in the groove, and the sliding rail is disposed inside the sliding seat.

The third purpose of the revolving shaft structure of the present invention is that the revolving shaft is made of metal material.

By the purpose, the abrasion problem caused by the conventional internal and external thread structure can be improved, the contact abrasion area of the steel balls is reduced, the service life is prolonged, and the maintenance steps can be simplified. However, the above description is only a preferred practical embodiment of the present invention, and not the scope of the present invention, so that the equivalent structural changes of the present invention, which are described in the specification and drawings, are all included in the scope of the present invention, and it is well known.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1-3, the present invention is a revolving shaft structure, which comprises: a revolving body 10, a groove 11 for embedding a sliding mechanism 40 is provided above the revolving body, the sliding mechanism 40 is composed of a sliding base 41 and a sliding rail 42, the sliding base 41 is embedded in the groove 11, then the sliding rail 42 is arranged on the track in the sliding base 41, a through groove 12 and a through hole 13 communicated with the through groove 12 are further provided in the revolving body 10, wherein the through hole 13 vertically penetrates through the through groove 13.

A revolving shaft 20 made of metal material, a revolving caulking groove 21 is carved on the outer circumference of the revolving shaft 20; the outer side of the rotating sleeve 30 is respectively provided with a limiting hole 310 and at least one embedding hole 311, and the embedding hole 311 is internally provided with a steel ball 32.

Referring to fig. 4-5, after the inner side of the rotary sleeve 30 is sleeved with the rotary shaft 20, the rotary sleeve is further disposed in the through groove 12, the steel ball 32 abuts against the inner wall 121 of the through groove 12 and the rotary caulking groove 21, and a positioning rod 14 is inserted into the limiting hole 310 through the through hole 13, as shown by the arrow in fig. 5, which is the distance that the rotary shaft 20 can be displaced by the positioning rod 14, so that the rotary shaft 20 can be restricted by the steel ball 32 to perform a rotary motion.

In summary, the innovative structure design of the revolving shaft structure of the present invention changes the precision processing requirement of the rotation movement of the internal thread and the external thread, which is commonly used originally, into that the revolving caulking groove 21 of the revolving shaft 20 is matched with the revolving sleeve 30 and arranged in the through groove 12 of the revolving body 10, and the limiting hole 310 of the revolving sleeve 30 is matched with the positioning rod 14 to form the limitation, and the steel ball 32 is arranged in the caulking hole 311 of the revolving sleeve 30, so that the steel ball 32 can be pushed against the revolving caulking groove 21 and the inner wall 121 of the through groove 12, the friction loss generated by the rotation of the revolving shaft 20 can be improved, thereby prolonging the service life of the components and reducing the complicated steps of maintenance.
