Description
Technical Field
The utility model relates to a cylinder part's technical field, in particular to rotatory air flue structure.
Background
The air cylinder is usually connected with an air inlet pipe and an air outlet pipe, when the air cylinder rotates, the air inlet pipe and the air outlet pipe can be wound, the inconvenience of the work of the air cylinder is caused, the normal action of the air cylinder is influenced, and the air pipe is easy to damage.
Disclosure of Invention
To the technical problem, the utility model provides a rotatory air flue structure, its simple structure when can realizing admitting air of cylinder and giving vent to anger, effectively prevents tracheal winding, has guaranteed the normal action of cylinder, has avoided tracheal damage.
The technical scheme is as follows: a rotating airway structure characterized by: the air channel structure comprises an annular inner ring, the annular inner ring is clamped and connected with an annular outer ring, the annular outer ring rotates around the annular inner ring, at least two annular air channels are arranged between the annular inner ring and the annular outer ring, air inlet connectors corresponding to the air channels are arranged on the annular inner ring and are respectively connected with the air channels, air outlet connectors corresponding to the air channels are arranged on the annular outer ring, and the air outlet connectors are respectively communicated with the air channels.
The sealing device is further characterized in that first sealing rings are arranged at two ends of the joint of the annular inner ring and the annular outer ring, and a second sealing ring is arranged between air passages at the joint of the annular inner ring and the annular outer ring; the annular outer ring is provided with a buckle corresponding to the annular inner ring.
The utility model adopts the above structure, annular inner circle card and connection annular outer lane, annular outer lane card is rotatory around annular outer lane, be provided with two at least annular air flues between annular inner circle and annular outer lane, annular inner circle is provided with the air inlet connector who corresponds with the air flue, the air flue is connected respectively to the air inlet connector, be provided with the joint of giving vent to anger that corresponds with the air flue on the annular outer lane, the joint of giving vent to anger communicates the air flue respectively, so when the cylinder is rotatory, can guarantee corresponding air inlet connector and give vent to anger to connect forever through the air flue, because annular inner circle and annular outer lane can relative rotation, can guarantee among the cylinder rotating assembly with the air inlet connector of external trachea connection or give vent to anger to connect fixedly, when the cylinder is rotatory, when realizing the admitting air of cylinder and giving vent to anger, effectively prevent tracheal winding, the normal action of cylinder has been guaranteed, tracheal damage has been avoided.
Drawings
FIG. 1 is a schematic front view of the rotary air passage structure of the present invention;
FIG. 2 is a left side view of FIG. 1;
fig. 3 is an enlarged view of a direction a of fig. 2.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1, 2 and 3, a rotary air passage structure comprises an annular inner ring 1, an annular inner ring clamp 1 and a connecting annular outer ring 2, wherein the annular outer ring 2 rotates around the annular inner ring 1, two annular air passages 3-1 and 3-2 are arranged between the annular inner ring 1 and the annular outer ring 2, the annular inner ring 1 is provided with air inlet connectors 4-1 and 4-2 corresponding to the air passages 3-1 and 3-2, the air inlet connectors 4-1 and 4-2 are respectively connected with the air passages 3-1 and 3-2, the annular outer ring 2 is provided with air outlet connectors 5-1 and 5-2 corresponding to the air passages 3-1 and 3-2, the air outlet connectors 5-1 and 5-2 are respectively communicated with the air passages 3-1 and 3-2, and two ends of the joint of the annular inner ring 1 and the annular outer ring 2 are provided with first sealing rings 6-1, 6-2, 6-2, a second sealing ring 7 is arranged between air passages 3-1 and 3-2 at the joint of the annular inner ring 1 and the annular outer ring 2, so that when the cylinder rotates, the air passage can ensure that the corresponding air inlet connector and the air outlet connector are communicated forever, and because the annular inner ring and the annular outer ring can rotate relatively, the air inlet connector or the air outlet connector connected with an external air pipe in the cylinder rotating assembly can be ensured to be fixed, when the cylinder rotates, the air inlet and the air outlet of the cylinder are realized, the winding of the air pipe is effectively prevented, the normal action of the cylinder is ensured, and the damage of the air pipe is avoided.
The annular outer ring 2 is provided with the buckle 8 corresponding to the annular inner ring 1, so that the annular inner ring is prevented from transversely moving and falling, and the stability of relative rotation of the annular outer ring and the annular inner ring is ensured.
In this embodiment, adopted two air flues, of course also can adopt the air flue of other quantity, as long as guarantee with the air inlet connector of external trachea connection or give vent to anger to connect fixedly, when revolving cylinder, external pipeline can not follow the rotation, prevent that external pipeline from twining, all be the utility model discloses a protection scope.
Give vent to anger and connect the definition that is only a name with giving vent to anger, the rotation of annular outer lane and annular inner circle is also relative, and the annular outer lane can be rotatory around annular inner circle, and of course the annular inner circle also can be rotatory around annular outer lane, as long as set up one of them to fixed, and the gas coupling above it is connected with external trachea, prevents its rotation and makes external trachea rotatory, prevents external trachea winding, all is the utility model discloses a protection scope.
The present invention and the embodiments thereof have been described above schematically, and the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, and as long as the person skilled in the art receives the teaching, without departing from the spirit of the present invention, the present invention shall not be limited to the embodiments and the structural modes similar to the technical solution, but also shall belong to the protection scope of the present invention.
