Abstract
The utility model relates to a part of a cleaning tool and in particular relates to a vacuum cleaner vacuum tube with a hose with a bending preventing protection block. The vacuum tube comprises a bend, the hose, a hose coupler and a retainer ring, wherein the hose coupler is arranged at the joint of the bend and the hose and has a sealing effect; and the retainer ring is sleeved in the hose to join the hose and the bend firmly. The vacuum tube is characterized in that brim-shaped extension parts matched with each other are respectively arranged below the rear of connection parts of the bend and the retainer ring; and the inner wall of the brim-shaped extension part on the retainer ring is matched with the arc-shaped outer wall of the connection part of the hose. The vacuum tube is simple in structure, long in service life, good in effect and convenient to manufacture.
Description
Technical field
The utility model relates to a kind of parts of cleaning device.Especially a kind of dust collecting tube of dust collector, the dust collecting tube of dust collector of the specifically anti-folding protection of flexible pipe band piece.
Background technology
Dust catcher has become the household electrical appliance that western countries are generally used now, almost popularizes in each household family, and market is very wide.
Dust catcher is constantly pulled back and forth due to sweep-up pipe in the course of the work, and flexible pipe exists often by the bending situation, the as easy as rolling off a log appearance cracking of the connecting portion of the flexible pipe of sweep-up pipe and bend pipe after long-term the use, and dust catcher often can't use because of the flexible pipe cracking.This defect has been brought inconvenience and has brought worry to manufacturer to the consumer.Visible slight flexible pipe has but become the critical position of dust catcher.This problem has caused insider's attention, all manages to improve these parts.
Summary of the invention
The purpose of the utility model be to society, disclose a kind of simple in structure, easy to make, the dust collecting tube of dust collector of the anti-folding protection of the effective flexible pipe band of long service life piece.
Technical solution adopted in the utility model is such:
The dust collecting tube of dust collector of the anti-folding protection of a kind of flexible pipe band piece, comprise hose coupling that bend pipe, flexible pipe, described bend pipe and described flexible pipe convergence part seal, be inserted in described flexible pipe described flexible pipe and described bend pipe are connected to firmly collar; It is characterized in that, the connecting portion back lower place of described bend pipe and collar all is provided with the extension of a shade shape cooperatively interacted, and the inwall of the extension of the shade shape of this collar and the connecting portion arc outer wall of described flexible pipe are suitable.The extension of the shade shape of this collar is holding in the palm flexible pipe all the time, prevents that the convergence part of flexible pipe and bend pipe is bent damage.
Take after above-mentioned technical measures compared with prior art its advantage to be:
Because the connecting portion of described bend pipe and collar all is provided with the extension of a shade shape cooperatively interacted; the inwall of the extension of the shade shape of this collar and the connecting portion arc outer wall of described flexible pipe are suitable; so flexible pipe is with after bend pipe is connected; the connecting portion of flexible pipe is subject to the protection of the extension of collar and bend pipe connecting portion shade shape; while making in the dust catcher operation process that sweep-up pipe is constantly pulled back and forth, flexible pipe can be by bending, thereby has extended the service life of flexible pipe.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment Split type structure schematic diagram;
Fig. 3 is dust catcher overall structure schematic diagram;
Fig. 4 is former dust collecting tube of dust collector structural representation;
Fig. 5 is former dust catcher overall structure schematic diagram.
The specific embodiment
Each Reference numeral title in accompanying drawing is:
The extension 32 of suction head of suction cleaner 1, long straight tube 2, bend pipe 3, former bend pipe 3 ', buckle 31, bend pipe back lower place shade shape, flexible pipe 4, dust collector host 5, collar 6, card button 61, the extension 62 of collar back lower place shade shape, hose coupling 7.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The dust collecting tube of dust collector of the anti-folding protection of a kind of flexible pipe band piece, comprise hose coupling 7 that bend pipe 3, flexible pipe 4, described bend pipe and described flexible pipe convergence part seal, be inserted in described flexible pipe described flexible pipe and described bend pipe are connected to firmly collar 6; It is characterized in that, the connecting portion back lower place of described bend pipe 3 and collar 6 all is provided with the extension 32,62 of a shade shape cooperatively interacted, and the inwall of the extension of the shade shape of this collar and the connecting portion arc outer wall of described flexible pipe are suitable.
The connecting portion of described bend pipe 3 and collar 6 all is provided with the extension 32,62 of a shade shape cooperatively interacted; the inwall of the extension 32 of the shade shape of this collar and the connecting portion arc outer wall of described flexible pipe are suitable; so flexible pipe 4 is with after bend pipe 3 is connected; the connecting portion of flexible pipe 4 is subject to the protection of the extension 32,62 of collar and bend pipe connecting portion shade shape; while making in the dust catcher operation process that sweep-up pipe is constantly pulled back and forth, flexible pipe 4 can be by bending, thereby has extended the service life of flexible pipe.
The buckle 31 at bend pipe 3 rear portions matches with the card button 61 on collar 6.Because collar 6 is inserted in flexible pipe 4, when collar 6 inserts bend pipe 3, card button 61 springs on collar 6 are first compressed; One be inserted on bend pipe 3 buckle 31 place the time, spring stretches, card button 61 is sprung in the buckle 31 on bend pipe 3, has solved flexible pipe 4 and the close-connected problem of bend pipe 3.
