Summary of the invention
The utility model provides a kind of high pulling torque high life rotary buffer simple in structure, easy to manufacture for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of high pulling torque high life rotary buffer, comprise housing, described housing one end opening, the inner cylindrical chamber that forms, be arranged with the longitudinal rib body on the inner peripheral surface of described chamber, the chamber interior of described housing is fitted with the axis of rotation of metal material, one end of described axis of rotation has connection handle, described connection handle stretches out described housing, the openend of described housing is equipped with end cover, symmetrical blade is installed on the described axis of rotation, it is characterized in that: be positioned on the outer circumference surface of axis of rotation of described enclosure interior and be coated with wearing layer.
The utility model can also adopt following technical scheme:
The external surface of described wearing layer is periphery.
The external surface of described wearing layer is the curved surface of the circumferential gradual change of radius.
Described wearing layer is plastic material.
Described wearing layer is nylon material.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, namely the external surface in the rotating shaft of snubber adds one deck wearing layer, greatly reduce the wearing and tearing between the longitudinal rib body of rotating shaft and enclosure interior, application life that can the significant prolongation snubber.

The specific embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1-Fig. 5, a kind of rotary buffer, its structure comprises an end opening, the inner housing 1 of cylindrical chamber and the indoor axis of rotation 2 of cylindrical cavity that is inserted into housing 1 of forming, part in the axis of rotation 2 is positioned at the cylindrical cavity chamber interior of housing 1, another part of axis of rotation 2 is positioned at the outside of housing 1, inside and outside two parts of axis of rotation 2 by suit axis of rotation 2 and be fixed on the openend of housing 1 end cover 3 separately, end cover 3 makes housing 1 with axis of rotation 2 sealing fits and forms annular seal space, is marked with damping oil in the annular seal space.The inwall of housing 1 is provided with symmetrical longitudinal rib body 1-1, the outer wall of housing 1 is provided with for the card muscle 1-3 that installs, axis of rotation 2 is positioned at housing 1 an outer end and has connection handle 2-1, the part that axis of rotation 2 is positioned at housing 1 is arranged with latch 2-2, the external surface that axis of rotation 2 inserts the part of housing 1 coats wearing layer 6, in the present embodiment, wearing layer 6 is plastic material or nylon, and the external surface of wearing layer 6 is curved surfaces of radius gradual change.The material of housing 1 is PBT, the material of axis of rotation 2 is metal, it is housing 1, be positioned at the longitudinal rib body 1-1 on housing 1 inwall and be positioned at the integrative-structure that the card muscle 1-3 on housing 1 outer wall is made by the PBT material, axis of rotation 2, being positioned at latch 2-2 on the axis of rotation 2 and the connection handle 2-1 of axis of rotation 2 one ends is integral structures of being made by metal material, so axis of rotation 2 can guaranteed, under the prerequisite of latch 2-2 intensity, reduce to a certain extent the size of axis of rotation, thereby reduce the overall dimensions of snubber, dwindle snubber shared space is installed, order is installed more attractive in appearance.In this non-limiting embodiment, the metal material that is used for making rotating shaft 2 and latch 2-2 is kirsite or magnesium alloy, because of the magnesium alloy high cost, selects zinc alloy material in the present embodiment.
The inside, bottom surface of housing 1 is positioned at longitudinal rib body 1-1 both sides and is equipped with oil pressure guiding gutter 1-2, above-mentioned axis of rotation 2 is the buffering direction of rotation of snubber from the direction that a side direction that has oil duct 4-2 on the blade 4 has the sideway swivel of buffering plane 4-3 on it, and the cell body width from its end to end reduces oil pressure guiding gutter 1-2 gradually from the buffering direction of rotation of snubber.
Two latch 2-2 that the curved surface of the radius gradual change of above-mentioned wearing layer is rotated on the axle 2 are divided into two parts, every part curved surface is made of three sections circular arc cambers, the side with buffering plane 4-3 to another blade 4 is made as the first circular arc buffering suface 2-3 successively from the side with oil duct 4-2 of a blade 4 on the axis of rotation 2, the second circular arc buffering suface 2-4 and three-arc buffering suface 2-5, and the radius of cambered surface increases successively.In laying respectively at latch both sides two parts curved surface, the arc length of three-arc buffering suface is greater than the arc length of the three-arc buffering suface of its opposite side.
Above-mentioned embodiment only is to functional descriptions of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model; external surface such as wearing layer is periphery, all drops within the protection domain of the present utility model.
