Description
Technical field:
The present invention relates to dust collector expansion pipe seal member and a kind of dust collector expansion pipes.
Background technique:
It include the dust catcher master that can generate suction and the air classification collection of material by sucking in usual vacuum cleaner
Body, and the brush used when the foreign matters such as the suction sucking outside air being arranged by the main body of dust collector and the dust being inhaled into
Assembly, and when foreign matter and air that are sucked by brush combination body are drawn into again in air cleaner main body use it is flexible
The components such as pipe, handle component, bending type hose composition.
The seal member that original telescoping tube is embedded at the front end (connecting pin with outer tube) of inner tube, the end of seal member
Inner tube is stretched out in portion and the end diameter of seal member is suitable with outer tube diameter, is stretched out after the completion of inner and outer pipe suit by seal member
Sealing is formed between the end and outer tube of inner tube.Due to traditional seal member end face be equipped with one section of ring segment be used for in outer tube
Sealing is formed between wall, but ring segment can not be bonded well with outer pipe internal surface, there is a degree of gas leak phenomenon；And it seals
Component generates more serious abrasion after a period of use, and service life is shorter, aggravates gas leak phenomenon, influences vacuum cleaner
Performance.
Utility model content:
The technical problems to be solved by the present invention are: providing a kind of dust collector expansion pipe sealing of good seal performance
Part.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows: dust collector expansion pipe seal member, packet
The outer segment to link together, middle section and inner segment are included, inner segment is fastened in inner tube, is equipped with and locating recesses phase in inner tube in the middle part of inner segment
The circular orientation groove of cooperation, inner segment periphery are respectively equipped at least one of ring packing raised line in positioning groove two sides, on middle section
Positioning convex platform equipped with limitation inner tube pipe end, outer segment outer diameter are gradually increased along far from inner tube direction, and the outer segment includes and middle section
What is be connected is less than the port part of middle section thickness in the engaging portion of cone tube shape and thickness, and the port part periphery of outer segment is equipped with extremely
Few one of ring packing raised line.
As a preferred solution, the port part periphery of the outer segment is equipped with twice annular sealed batten, wherein separate
The outer diameter of the ring packing raised line of inner tube is equal to outer pipe outside diameter, and the outer diameter close to the ring packing raised line of inner tube is equal in outer tube
Diameter.
As a preferred solution, inner segment periphery is respectively equipped with twice outer diameter equal to inner tube outside diameter in positioning groove two sides
Ring packing raised line.
As a preferred solution, positioning convex platform is equipped with the sealing bulge loop that at least one of outer diameter is equal to outer tube diameter；
Ring packing raised line two sides on the inner segment are respectively equipped with annular groove；Inner segment end is equipped with fillet surface.
The beneficial effects of the present invention are: since sealed batten and inner tube, outer is respectively adopted in the inner segment and outer segment of seal member
Pipe forms sealing, and sealed batten can preferably be bonded tube wall, and sealing effect is good.
Due to the outer segment include be connected with middle section be less than middle section thickness in the engaging portion of cone tube shape and thickness
Port part, port part wall thickness is smaller, and corresponding deformation is generated under the constraint of outer tube wall, can be preferably bonded in outer tube
Wall, to improve sealing effect；And the setting of cone tube shape engaging portion is so that the deformation of port part will not be conducted to seal member
Middle section and inner segment, keep the sealing between seal member and inner tube unaffected.
Since the port part periphery of outer segment is equipped with twice annular sealed batten, wherein the ring packing raised line far from inner tube
Outer diameter is equal to outer pipe outside diameter, which can resist more long use friction, to improve the use longevity of seal member
Life；And it is equal to outer tube diameter close to the outer diameter of the ring packing raised line of inner tube, so that the sealing effect between outer segment and outer tube is more preferable.
Since inner segment periphery is respectively equipped with the ring packing raised line that twice outer diameter is equal to inner tube outside diameter in positioning groove two sides,
The sealed batten can resist more long use friction, to improve the service life of seal member.
Since positioning convex platform is equipped with the sealing bulge loop that at least one outer diameter is equal to outer tube diameter so that seal member with it is interior
Sealing effect is more preferable between pipe；
Since the ring packing raised line two sides on the inner segment are respectively equipped with annular groove, so that seal member and inner tube, outer
When pipe assembles, ring packing raised line is not easy to be broken due to pushing because rubbing；
Since inner segment end is equipped with fillet surface, convenient for the assembly of seal member and inner tube.
The present invention another the technical problem to be solved is that: provide the dust collector expansion pipe of good seal performance a kind of with close
Seal component.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows: dust collector expansion pipe, including outer tube are sliding
The inner tube being set in the outer tube is moved, is embedded with substantially cylindrical seal member at the front end of inner tube, seal member
Inner tube is stretched out in end, and several card slot column are provided in inner tube, and each column card slot, which is arranged, is arranged at intervals with multiple cards along length direction
Slot；It is mounted on the length tune that the rear end of the outer tube adjusts flexible length of tube for selectively fixing said inner tube on outer tube
Integeral part, the seal member are the seal member in any of the above-described.
The beneficial effects of the present invention are: due to using novel seal member, so that the leakproofness of this dust collector expansion pipe
It can greatly improve.
