For solving above-mentioned technical problem, the technical solution adopted in the present invention is: dust collector expansion pipe seal member, including the outer section linked together, stage casing and inner segment, inner segment is fastened in interior pipe, the circular orientation groove matched with locating recesses on interior pipe it is provided with in the middle part of inner segment, inner segment periphery is respectively provided on two sides with at least one ring packing raised line at detent, stage casing is provided with the positioning boss of the interior pipe pipe end of restriction, outer section of external diameter is along being gradually increased away from interior pipe direction, the described outer section of joint portion in circular cone tubular including being connected with stage casing and thickness are less than the port part of stage casing thickness, the port part periphery of outer section is provided with at least one ring packing raised line.
As the preferred scheme of one, the port part periphery of described outer section is provided with twice annular sealed batten, and wherein away from the external diameter of the ring packing raised line of interior pipe equal to outer tube external diameter, the external diameter near the ring packing raised line of interior pipe is equal to outer tube diameter.
As the preferred scheme of one, inner segment periphery is respectively provided on two sides with the twice external diameter ring packing raised line equal to interior pipe external diameter at detent.
As the preferred scheme of one, positioning boss is provided with at least one external diameter sealing bulge loop equal to outer tube diameter；Ring rib on described inner segment is respectively provided on two sides with cannelure；Inner segment end is provided with fillet surface.
The invention has the beneficial effects as follows: formed with interior pipe, outer tube seal owing to the inner segment of seal member and outer section are respectively adopted sealed batten, sealed batten can be fitted tube wall preferably, good sealing effect.
Owing to the described outer section joint portion in circular cone tubular including being connected with stage casing and thickness are less than the port part of stage casing thickness, port part wall thickness is less, producing corresponding deformation under the constraint of wall within the outer tube, outer tube wall of fitting better, thus improving sealing effectiveness；And the setting of circular cone tubular joint portion makes the deformation of port part will not be conducted to stage casing and the inner segment of seal member, make the sealing between seal member and interior pipe unaffected.
Owing to the port part periphery of outer section is provided with twice annular sealed batten, wherein away from the external diameter of the ring packing raised line of interior pipe equal to outer tube external diameter, this road ring packing raised line can resist use friction more of a specified duration, thus improving the service life of seal member；And near the external diameter of ring packing raised line of interior pipe equal to outer tube diameter so that the sealing effectiveness between outer section and outer tube is better.
Owing to inner segment periphery is respectively provided on two sides with the twice external diameter ring packing raised line equal to interior pipe external diameter at detent, this sealed batten can resist use friction more of a specified duration, thus improving the service life of seal member.
Owing to positioning boss is provided with at least one external diameter sealing bulge loop equal to outer tube diameter so that between seal member and interior pipe, sealing effectiveness is better；
Owing to the ring rib on described inner segment is respectively provided on two sides with cannelure so that when seal member and interior pipe, outer tube assembling, ring rib is not easy to rupture because friction is pushed；
Owing to inner segment end is provided with fillet surface, it is simple to the assembling of seal member and interior pipe.
The present invention to be solved technical problem is that another: provides the dust collector expansion pipe seal member of a kind of good seal performance.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: dust collector expansion pipe, including outer tube, be slidably located in the interior pipe in described outer tube, the front end place of interior pipe is embedded with seal member substantially cylindrically, interior pipe is stretched out in the end of seal member, interior pipe is provided with some draw-in grooves row, each column draw-in groove row are arranged at intervals with multiple draw-in groove along length direction；The rear end being arranged on described outer tube adjusts the length adjusting elements of telescoping tube length for optionally fixing said inner tube on outer tube, and described seal member is the seal member in any of the above-described item.
The invention has the beneficial effects as follows: owing to adopting novel seal member so that the sealing property of this dust collector expansion pipe is greatly improved.
