Keep and the good sealing effectiveness of scrubbing brush elbow internal wall.But during attachment tab is separated with scrubbing brush bend pipe, due to ground
There is bend pipe hole in brush bend pipe, the deformation of contact site can aggravate at bend pipe hole, can so allow sealing ring to have situation about turning up to occur,
Whole accessory assembly therefor sealing effectiveness is caused to be deteriorated, so as to influence dust catcher performance.
Utility model content
The utility model purpose is：A kind of scrubbing brush winding pipe assembly for preventing sealing ring from overturning is provided, its is simple in construction, passes through
Scrubbing brush bend pipe is contacted with sealing ring gradual change, prevents sealing ring from turning up, and sealing effectiveness is good, and cost is low and durable in use.
The technical solution of the utility model is：A kind of scrubbing brush winding pipe assembly for preventing sealing ring from overturning, it at least includes：Stretch
The draw, the attachment tab for being fixedly connected on telescoping tube one end, at least part house the scrubbing brush bend pipe of attachment tab one end, are arranged on
On scrubbing brush bend pipe and the snap close piece that attachment tab can be fixedly connected with scrubbing brush bend pipe and be set in attachment tab and with ground
The sealed sealing ring of brush elbow internal wall, wherein the sealing ring includes base portion and integrally extended by base portion and extended with base portion
Contact site at an acute angle is intersected in direction, and at least partially transitional surface is contacted between contact site and scrubbing brush elbow internal wall.
On the basis of above-mentioned technical proposal, further comprise following attached technical scheme：
The acute angle is less than 45 degree.
The maximum gauge of the contact site is more than the inner diameter of scrubbing brush bend pipe, to ensure sealing.
At least partially guiding surface is contacted between the contact site and scrubbing brush elbow internal wall.
The contact site at least partially guiding surface.
Also include the annex cover plate set around attachment tab and the bend pipe cover plate set around scrubbing brush bend pipe.
The scrubbing brush bend pipe is provided with bend pipe hole, and attachment tab is provided with joint recess, and snap close piece one end is provided with can
The lock head being pivoted, wherein lock head through bend pipe hole and with joint recess snap fit.
The bend pipe hole is at least partly triangular in shape, and two sides and the contact site abutting contact, two of which of triangle
While joining telescoping tube depart from scrubbing brush bend pipe when compared with two while prior to touching contact site.
The triangle is right angled triangle, and the inwall on two sides has guiding surface.
The utility model advantage is：
The utility model is simple in construction, is contacted by scrubbing brush bend pipe with sealing ring gradual change, prevents sealing ring from turning up, sealing effect
Really good, cost is low and durable in use.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Fig. 1 is sectional view of the present utility model；
Fig. 2 is the sectional view of sealing ring in the utility model；
Fig. 3 is the top view of scrubbing brush bend pipe in the utility model.
Embodiment
Embodiment：As Figure 1-3, the utility model provides a kind of scrubbing brush winding pipe assembly for preventing sealing ring from overturning
Specific embodiment, it includes telescoping tube 10, the attachment tab 1 for being fixedly connected on the one end of telescoping tube 10, set around attachment tab 1
Annex cover plate 2, at least partly house the scrubbing brush bend pipe 3 of attachment tab 1 one end, set on scrubbing brush bend pipe 3 and annex can be connect
First 1 snap close piece 4 being fixedly connected with scrubbing brush bend pipe 3, the bend pipe cover plate 5 set around scrubbing brush bend pipe 3 and it is set in annex and connects
On first 1 and with the sealing ring 6 of the inner wall sealing of scrubbing brush bend pipe 3, wherein sealing ring 6 includes base portion 60 and by base portion 60 integrally being prolonged
Stretch and intersect contact site 62 at an acute angle with the bearing of trend of base portion 60, the acute angle is preferably smaller than 45 degree.
Attachment tab 1 is provided with seal groove 12, the joint recess 14 adjacent with seal groove 12 for accommodating sealing ring 6.
Scrubbing brush bend pipe 3 include housing the host cavity 30 of attachment tab 1 one end, part accommodate sealing ring 6 groove 32 and
The bend pipe hole 34 being connected with host cavity 30.Bend pipe hole 34 is at least partly triangular in shape, and triangle two sides 340 with contacting
The abutting contact of portion 62, two of which while 340 joining when telescoping tube 10 departs from scrubbing brush bend pipe 3 compared with two while 340 prior to connecing
Contact contact site 62.Triangle is preferably right angled triangle, and the inwall on two sides 340 has guiding surface.
One end of snap close piece 4 is provided with the lock that can be pivoted first 40 and the other end is then provided with spring, wherein latching
First 40 through bend pipe hole 34 and with the snap fit of joint recess 14.
During scrubbing brush bend pipe 3 is extracted, because the maximum gauge of contact site 62 of sealing ring is more than in scrubbing brush bend pipe 3
Wall diameter, the deformation of contact site 62 concentrates on bend pipe hole 34, so that stress is outwards overturn.Therefore the utility model in order that both
Contact by contact area become greatly slowly transition, contacted by gradual change type, i.e., by the joining on two sides contact area by
