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
Usually comprise in the vacuum cleaner; Can produce suction and reach main body of dust collector through inhaled air categorised collection material; And the suction through said main body of dust collector setting sucks extraneous air and the brush assembly that uses during the foreign matters such as dust that are inhaled into, and parts such as the telescoping tube that uses when being drawn into the foreign matter that sucks through the brush assembly and air in the air main body of dust collector again, handle component, bending type flexible pipe are formed.
The seal member that original telescoping tube is located to be embedded at the front end (with the link of outer tube) of interior pipe; The pipe and end diameter and the outer tube diameter of seal member were suitable in stretched out the end of seal member, and the inner and outer pipe suit is accomplished the end and the outer tube that lean on seal member to manage in stretching out in the back and asked that formation seals.Owing to have the gap about 1mm between the inner and outer pipe; Inner and outer pipe produces and rocks during use, because inner and outer pipes length is longer, the value of rocking of pipe end can reach about 15mm; Influence is used; And be prone to make seal member stretch out in the end of pipe produce deformation, the sealing effectiveness variation influences the performance of vacuum cleaner.
Summary of the invention
Technical problem to be solved by this invention is: inner and outer pipes rocked vacuum cleaner telescoping tube little, good seal performance when a kind of the use was provided.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: the vacuum cleaner telescoping tube comprises outer tube, the interior pipe in the said outer tube that is slidingly located in; The front end place of interior pipe is embedded with seal member; Interior pipe is stretched out in the end of seal member, and interior pipe is provided with some draw-in groove row, and every row draw-in groove lists along length direction and is arranged at intervals with a plurality of draw-in grooves; The rear end that is installed in said outer tube be used on outer tube optionally fixing said in the length adjustment parts of pipe adjustment telescoping tube length, the front end sleeve of managing in said is provided with the sealing and reinforcing spare of pipe shape.
Said draw-in groove number of columns is two row, and isolates each other on the outer circumference surface of in said, managing, and said sealing and reinforcing spare is provided with two locating convex blocks that match with draw-in groove.
The periphery bottom of pipe is provided with along length direction and prevents the rail groove that rotates in said, and said sealing and reinforcing spare is provided with the anti-rotation projection that matches with rail groove.
Offer telescopic chute on the said sealing and reinforcing spare, telescopic chute is positioned at and axially connects whole sealing and reinforcing spare on the perpendicular bisector of two locating convex blocks.
Said sealing and reinforcing spare two ends respectively are provided with one and are convenient to sealing and reinforcing spare suit installation gap on inner pipe.
The invention has the beneficial effects as follows: owing to be arranged with sealing and reinforcing spare on the interior pipe, inner and outer pipe is played the support fixation effect, reduced rocking relatively of inner and outer pipe, make that this vacuum cleaner telescoping tube is easy to use; And avoided seal member distortion in use simultaneously, and sealing fixture itself also plays certain sealing function, strengthened vacuum cleaner telescoping tube sealing on the whole greatly, improved the serviceability of vacuum cleaner.
Because sealing and reinforcing spare is provided with two locating convex blocks that match with draw-in groove, make sealing and reinforcing spare that the difficult slip in back on inner pipe is installed.
Because sealing and reinforcing spare is provided with the anti-rotation projection that matches with rail groove, make that sealing and reinforcing spare is difficult for rotating with respect to interior pipe.
Owing to offer telescopic chute on the sealing and reinforcing spare, telescopic chute is positioned on the perpendicular bisector of two locating convex blocks and axially connects whole sealing and reinforcing spare, make sealing and reinforcing spare suit be set in pipe last time more easy.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
Be depicted as a kind of embodiment of vacuum cleaner telescoping tube like Fig. 1-6; Comprise outer tube 1, the interior pipe 2 in the said outer tube 1 that is slidingly located in, the front end place of interior pipe 2 is embedded with seal member 3; Pipe 2 in stretch out the end of seal member 3; In pipe 2 be provided with two row draw-in grooves row, and isolation each other on the outer circumference surface of pipe 2 said in, every row draw-in groove lists along length direction and is arranged at intervals with a plurality of draw-in groove 20l; The rear end that is installed in said outer tube l be used on outer tube l optionally fixing said in pipe 2 adjust the length adjustment parts 4 of telescoping tube length; The front end sleeve of pipe 2 is provided with the sealing and reinforcing spare 5 of pipe shape in said, and said sealing and reinforcing spare 5 is provided with two locating convex block 50l that match with draw-in groove 20l.In pipe 2 periphery bottom be provided with along length direction and prevent the rail groove 202 that rotates, sealing and reinforcing spare 5 is provided with the anti-rotation projection 502 that matches with rail groove 202.Offer telescopic chute 503 on the said sealing and reinforcing spare 5, telescopic chute 503 is positioned at and axially connects whole sealing and reinforcing spare 5 on the perpendicular bisector of two locating convex blocks 501.Sealing and reinforcing spare 5 two ends respectively be provided with one be convenient to sealing and reinforcing spare 5 be sleeved in the installation gap 504 of pipe on 2.
