The utility model discloses an overall structure, have easy dismounting, prevent not hard up, the sealed reliable advantage of rotating ring, applicable positive reverse operating mode simultaneously.
Description
[technical field]
The utility model relates to a kind of black box that is applied to pump series products inside.
[background technology]
At present, the being seen black box that is applied to pump series products inside on market, main existence is following notFoot: 1, adopt split-type structural, rotating ring and stationary ring are partial installations at pump body, so dismounting is notJust, be unfavorable for maintain and replace; 2, while work, between rotating ring and rotating seat, be prone to and relatively rotate, rotating ring producesGive birth to rotation phenomenon, can destroy the sealing reliability of black box; 3, because the spring of black box inside hasCertain rotation direction, makes the rotating ring of black box can only be applicable to one-directional rotation, rotates backward the torsion side with springTo on the contrary, spring fatiguability damages.
[summary of the invention]
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of adopt overall structure, dismountingConvenient, anti-locating snap ring becomes flexible, sealing is reliable, the black box of applicable forward and reverse operating mode simultaneously.
The utility model adopts following scheme to realize:
Black box, is characterized in that: comprise connecting axle and be from left to right sheathed on successively connecting axle cylindricalStationary seat, stationary ring, rotating ring, rotating seat, spring and spring base, the right-hand member of connecting axle is provided with and blocks spring baseThe annular protrusion moving to right, the left end of connecting axle is provided with and blocks the fixed screw that stationary seat moves to left, and stationary seat is with solidThe contact end face of determining between screw arranges pad, and stationary ring is arranged on stationary seat, and rotating ring is arranged on rotating seat,Under the elastic force effect of spring, the right side of stationary ring is adjacent to and contacts with the left side of rotating ring, described rotating seatLeft side arranges some the first square teeth, and right side arranges some the second square teeth, and described rotating ring cylindrical arranges and theProjection corresponding to one square tooth is inserted into the between cog of the first square tooth, and the left side of described spring base arranges and the second squareThe 3rd square tooth that tooth is corresponding, the second square tooth and the 3rd square tooth are crisscross arranged, and the second square tooth is inserted into the 3rd square toothBetween cog, the 3rd square tooth is inserted into the between cog of the second square tooth.
The endoporus of described annular protrusion arranges shaft seal O type circle, and rotating ring O type circle is set between rotating ring and rotating seat,Stationary ring O type circle is set between stationary ring and stationary seat.
In technique scheme, all parts of rotating ring, stationary ring and black box are all linked to be on connecting axleAn entirety, has adopted overall structure, and black box just can carry out integral disassembly, assembly at pump body like this,There is easy accessibility; In addition, the left side of rotating seat arranges some the first square teeth, and rotating ring cylindrical is establishedPut the between cog that the projection corresponding with the first square tooth is inserted into the first square tooth, so just can anti-locating snap ring and movingBetween ring seat, occur relatively rotating, i.e. the phenomenon of rotating ring rotation, guarantee sealing reliability; Further, rotating seatRight side arranges some the second square teeth, and the left side of spring base arranges the three square tooth corresponding with the second square tooth,The second square tooth and the 3rd square tooth intert mutually, so, when work between rotating seat and spring base just not yetThere will be and relatively rotate, so the setting of spring is just irrelevant with rotation direction, so it is forward and reverse to be applicable to pump shaftThe operating mode of rotating.
[brief description of the drawings]
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
[detailed description of the invention]
