Abstract
The utility model relates to a component of a dust collector, particularly a smooth hose which is exclusively used on the inner wall of the dust collector. The utility model has the technical proposal that a flexible belt is continuously wound to be made into a hose. The cross-sectional shape of the flexible belt is an approximate trapezoid which is composed of a front tube wall, an outer tube wall, and a rear tube wall. The bottom end of the rear tube wall is backwards bent and folded and extends to form the inner wall. The inner wall is composed of the front section of the inner wall, a transition section, and the tail section of the inner wall. A fin is arranged on the junction point of the front section of the inner wall and the transition section. After the hose is wound, the fin is positioned in the cavity of the trapezoid, and is firmly bonded with the front tube wall. The tail section of the inner wall is appressed with the inner surface of the front section of the inner wall of a posteriorsection. Then, the smooth telescopic hose of the inner wall is formed.
Description
The utility model relates to the dust catcher parts, specifically a kind of level and smooth flexible pipe of inwall that is exclusively used in dust catcher.
Existing dust collector hose forms by the soft band coiling that section is serpentine, after forming flexible pipe, " V " shape opening is radially arranged on the flexible pipe, make the flexible pipe inner surface be the interruption shape, start working at dust catcher, when air-flow flows, can increase resistance, the noise of generation in pipe, and at opening inner accumulated dust, influence pick-up performance, after after a while, the dust that gathers can have influence on the bending property of flexible pipe.
The purpose of this utility model is the level and smooth dust collector hose of a kind of endoporus of design, to reduce resistance, reduces noise, improves pick-up performance.
Its main technical schemes is that this flexible pipe is formed by a continuous coiling of soft band, the soft band section configuration preceding tube wall of serving as reasons, outer tube wall and back tube wall form an approximate trapezoid, bottom at the back tube wall bends backward and extends to form inwall, this inwall is by the inwall leading portion, changeover portion and inwall rear constitute, the inner surface of inwall leading portion along flexible pipe axially and the flexible pipe center at angle, the inner surface of inwall rear is axially parallel with the flexible pipe center along flexible pipe, seamlessly transit by crossing section between inwall leading portion and rear, the fin that oriented back upper place tilts to stretch out on the joint of inwall leading portion and changeover portion, the inwall rear begins to afterbody attenuation gradually from changeover portion, after soft band turns to flexible pipe, fin is positioned at the preceding tube wall of back one joint, in the trapezoidal chamber that outer tube wall and back tube wall form, and near preceding tube wall, the inwall rear is close to the inner surface of back one joint inwall leading portion, gapped between fin and preceding tube wall, between fin and back tube wall, the expansion joint is arranged, filling is used for the binding agent of bonding preceding tube wall and fin in the gap, the inner surface of inwall rear is parallel with the flexible pipe center, outer surface has the tapering that the inner surface with the inwall leading portion matches, the spongy elastomeric material of filling in the expansion joint between fin and back tube wall.
The utility model has the advantages that owing to after hose inner wall is made level and smooth formula, make hose inner wall almost be continuous surface, with original comparing, avoid original V-shaped part, reduced air drag, reduced noise and shake, easy to use, secondly, at fin both sides difference coating adhesive with after placing extra large bright and beautiful shape object, improved connection fastness and the air-tightness and the resilience of flexible pipe.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the amplification of A among Fig. 1.
As shown in the figure, this flexible pipe is formed by a continuous coiling of soft band, the section configuration of this soft band is preceding tube wall 2, outer tube wall 4, back tube wall 6 forms an approximate trapezoid, bends backward in the bottom of back tube wall 6 and extends to form inwall, this inwall is by inwall leading portion 10, changeover portion 9 and inwall rear 8 constitutes, the inner surface of inwall leading portion 10 along flexible pipe axially with flexible pipe center α at angle, the inner surface of inwall rear 8 is axial parallel with the flexible pipe center along flexible pipe.The outer surface of inwall rear 8 has the tapering that the inner surface with inwall leading portion 10 matches, inwall rear 8 begins to afterbody attenuation gradually from changeover portion, 8 of inwall leading portion 10 and rears are seamlessly transitted by changeover portion 9, the fin 7 that oriented back upper place tilts to stretch out on the joint of inwall leading portion and transition 9, after soft band turns to flexible pipe, the preceding tube wall 2 of a joint after fin 7 is positioned at ', outer tube wall 4 ' reach in the trapezoidal chamber of back tube wall 6 ' formation, and close preceding tube wall 2 ', inwall rear 8 be close to back one joint inwall leading portion 10 ' inner surface, guaranteeing hose inner wall smooth transition continuously, and scalable.Fin 7 and preceding tube wall 2 ' gapped 3 ', in the gap filling be used for bonding before tube wall 2 ' with the binding agent of fin 7, fin 7 and afterwards tube wall 6 ' have expansion joint 5 '.Among the figure, d, D are respectively external diameter in the flexible pipe, L is a total length, 2 ', 3 ', 4 ', 5 ', 6 ', 10 ' be respectively preceding tube wall, gap, outer tube wall, expansion joint, back tube wall, the inwall leading portion of back one joint, be respectively fin, the inwall rear of last joint, changeover portion, inwall leading portion 7 ", 8 ", 9 ", 10 ".
