Abstract
The invention discloses an expansion pipe for a vacuum cleaner, which comprises an outer pipe, an inner pipe sheathed in the outer pipe in a sliding mode and a length regulation element; the front end of the inner pipe is embedded with a sealing element; the end part of the sealing element extends out of the inner pipe; the inner pipe is provided with a plurality of trough rows; each trough row is provided with a plurality of troughs at intervals along the length direction; the length regulation element is installed on the rear end of the outer pipe and is used for selectively fixing the inner pipe on the outer pipe to regulate the length of the expansion pipe; and the front end of the inner pipe is sheathed with a circular-pipe-shaped sealing reinforcing member. The invention provides an expansion pipe for a vacuum cleaner, which has good sealing performance, and the inner pipe and the outer pipe are slightly shaken when the expansion pipe for a vacuum cleaner is used.
Description
Technical field
The present invention relates to vacuum cleaner, refer more particularly to a kind of vacuum cleaner telescoping tube.
Background technology
Conventionally vacuum cleaner comprises, the main body of dust collector of the air classification collection of material that can produce suction and pass through to suck, and the suction arranging by described main body of dust collector suck extraneous air and be inhaled into the foreign matters such as dust time the brush combination body that uses, and the parts such as the telescoping tube using when the foreign matter sucking by brush combination body and air are drawn in air main body of dust collector again, handle component, bending type flexible pipe form.
The seal member that original telescoping tube is located to be embedded at the front end (with the link of outer tube) of inner tube, end diameter and outer tube diameter that inner tube and seal member are stretched out in the end of seal member are suitable, after inner and outer pipe has been set with, by seal member, stretches out between the end of inner tube and outer tube and form and seal.Owing to there being the gap of 1mm left and right between inner and outer pipe, during use, inner and outer pipe produces and rocks, because inner and outer pipes length is longer, the value of rocking of pipe end can reach 15mm left and right, impact is used, and the end that easily makes seal member stretch out inner tube produces deformation, sealing effectiveness variation, affects the performance of vacuum cleaner.
Summary of the invention
Technical problem to be solved by this invention is: when a kind of use is provided, inner and outer pipes rocks vacuum cleaner telescoping tube little, good seal performance.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: vacuum cleaner telescoping tube, comprise outer tube, the inner tube being slidably located in described outer tube, the front end place of inner tube is embedded with seal member, inner tube is stretched out in the end of seal member, is provided with some draw-in groove row in inner tube, and every row draw-in groove lists along length direction and is arranged at intervals with a plurality of draw-in grooves; The length adjustment parts of telescoping tube length are adjusted in the rear end that is arranged on described outer tube for optionally fix described inner tube on outer tube, the front end sleeve of described inner tube is provided with the sealing and reinforcing part of circular tube shaped, the periphery bottom of described inner tube is provided with the rail groove that prevents rotation along length direction, is provided with the anti-rotation projection matching with rail groove on described sealing and reinforcing part.
Described draw-in groove number of columns is two row, and isolation mutually on the outer circumference surface of described inner tube, is provided with two locating convex blocks that match with draw-in groove on described sealing and reinforcing part.
On described sealing and reinforcing part, offer telescopic chute, telescopic chute is positioned at and on the perpendicular bisector of two locating convex blocks, axially connects whole sealing and reinforcing part.
Described sealing and reinforcing part two ends are respectively provided with one and are convenient to sealing and reinforcing part suit installation gap on inner pipe.
The invention has the beneficial effects as follows: owing to being arranged with sealing and reinforcing part in inner tube, inner and outer pipe is played to support fixation, reduced relatively rocking of inner and outer pipe, make this vacuum cleaner telescoping tube easy to use; And avoided seal member distortion in use, and sealing fixture itself also plays certain sealing function simultaneously, greatly strengthened on the whole vacuum cleaner telescoping tube sealing, improved the serviceability of vacuum cleaner.
Owing to being provided with two locating convex blocks that match with draw-in groove on sealing and reinforcing part, sealing and reinforcing part being installed and be difficult for afterwards on inner pipe sliding.
Owing to being provided with the anti-rotation projection matching with rail groove on sealing and reinforcing part, make sealing and reinforcing part be difficult for rotating with respect to inner tube.
Owing to offering telescopic chute on sealing and reinforcing part, telescopic chute is positioned on the perpendicular bisector of two locating convex blocks and axially connects whole sealing and reinforcing part, more easy while making sealing and reinforcing part be set in inner tube.
