Abstract
A hose for a vacuum cleaner. A connecting ring(1) is inserted in a hose(3) and a protrusion(2) is engaged with a hanging hole(6) formed on a coupling end(4a) of a hose connecting pipe(4). A front end connecting portion(3a) of the hose is inserted in an insertion hole(4c) formed by a connecting end(4b) integrally molded in the coupling end(4a) of the connection pipe. A protruded tooth portion(5) is integrally formed on the outer face of the front end connecting portion (3a) to close the insertion hole (4c).
Description
Technical field
The present invention relates to have the vacuum cleaner pipe connection of connecting portion air tight construction,, form the prominent ring of airtight usefulness at the connecting portion of the flexible pipe front end that embeds flexible pipe tube connector interior groove.
Background technology
Flexible pipe is inserted tube connector and when fastening, in order to keep tightening state conscientiously and easily, the insertion position of flexible pipe and tube connector should closely be connected airtight, like this, during the suction action of dust catcher, can not leak into the tube connector outside at the suction air of flexible pipe internal flow.
Usually, when being fastened on vacuum cleaner on the tube connector with flexible pipe, be on tube connector, to form the threaded portion, form and corresponding threaded portion, above-mentioned tube connector threaded portion in the connection end of flexible pipe, they are screwed togather mutually.Perhaps use other attaching parts (for example screw etc.) to connect.
But, in the former the connection structure, unclamp easily owing to screw togather the position, must observe at any time and it be tightened, cumbersome.When adopting other attaching parts in order to address this problem, must tighten several screws one by one, it is also cumbersome that it connects operation, and efficient is low.
In order to address the above problem, following jockey has been proposed in the prior art, that is, the connecting ring of being equipped with the card jaw integratedly is enclosed within on the flexible pipe, form hole clipping in the connection end of flexible pipe tube connector, the card jaw of above-mentioned connecting ring is embedded in this hole clipping engage.Like this, available simple structure becomes easily terminal operation, and can keep its tightening state conscientiously.
But when being connected that the end is not connected airtight mutually of the connecting portion of flexible pipe and tube connector and when producing the gap, sucking air will pass through this clearance leakage, the result causes the inhalation power reduction.
Summary of the invention
The purpose of this invention is to provide a kind of vacuum cleaner pipe connection with air tight construction, this vacuum cleaner is fastened on the tube connector with flexible pipe, available simpler structure makes terminal operation become easy, and can keep tightening state conscientiously, the connecting portion of flexible pipe and tube connector, simple structure can be connected airtight airtightly conscientiously, prevents to suck air and spills the outside.

The specific embodiment
Below, the technology contents that present invention will be described in detail with reference to the accompanying.
Vacuum cleaner pipe connection with connecting portion air tight construction of the present invention, the dead ring 1 of being equipped with card jaw 2 integratedly is enclosed within on the flexible pipe 3, outer connection end 4a at flexible pipe tube connector 4 forms hole clipping 6, the card jaw 2 of above-mentioned dead ring 1 is embedded in this hole clipping 6, wherein, in connect within the outer connection end 4a that end 4b is formed in tube connector 4 integratedly and its free end and the hole clipping 6 certain distance apart that is connected on the 4a of end outward, the front end connecting portion 3a of flexible pipe 3 is embedded by inside and outside connection end 4b, the flexible pipe that 4a forms inserts in the district 4c, form the prominent ring 5 of airtight usefulness in the outside of above-mentioned front end connecting portion 3a, it is airtight that flexible pipe is inserted district 4c.
Among the figure, the bending supporting jaw that unaccounted mark 1a is a dead ring 1,6a is formed in the outer inclined plane that connects end 4a front end, is used to make card jaw 2 to embed hole clipping 6 neatly.
In the present embodiment, as shown in Figure 2, be darted at the prominent ring 5 of airtight usefulness on the flexible pipe front end connecting portion 3a integratedly, be formed in the lateral surface of front end connecting portion 3a.Among another embodiment, as shown in Figure 3, the prominent ring 5 of this airtight usefulness is formed on the medial surface of front end connecting portion 3a.Among the another embodiment, as shown in Figure 4, the prominent ring 5 of this airtight usefulness is formed on the inside and outside two sides of front end connecting portion 3a.Can select as required above-mentioned any.
As mentioned above, form hole clipping 6, card jaw 2 these hole clippings 6 of embedding and the joint of dead ring 1 are lived, can utilize existing bindiny mechanism that flexible pipe 3 is connected with tube connector 4 at the outer connection end 4a of tube connector 4.At this moment, the flexible pipe that is embedded in the connection end of tube connector 4 inserts the prominent ring 5 of airtight usefulness of the front end connecting portion 3a in the district 4c, makes that connecting airtight the flexible pipe that inserts front end connecting portion 3a and tube connector 4 on the district 4c at flexible pipe inserts to distinguish between the 4c and do not produce the gap.
As mentioned above, be equipped with the dead ring 1 of card jaw 2 with additionally being made into one, it is enclosed within on the flexible pipe 3, outer connection end 4a at tube connector 4 forms hole clipping 6, above-mentioned card jaw 2 embeds this hole clipping 6 and is bonded with each other, by adopting this simple bindiny mechanism, tube connector 4 and flexible pipe 3 are coupled together, at this moment, because the front end connecting portion 3a with the prominent ring 5 of airtight usefulness is formed on the front end of flexible pipe 3, so the flexible pipe that this front end connecting portion 3a inserts tube connector 4 inside inserts among the district 4c, it is airtight by the prominent ring 5 of airtight usefulness flexible pipe to be inserted district 4c, does not produce the gap.Therefore, when carrying out the vacuum cleaning action, the suction air in the flexible pipe 3 does not leak into the outside fully, can keep inhalation power conscientiously, and the air that improves vacuum cleaner sucks effect.
In addition, because the prominent ring 5 of front end connecting portion 3a and airtight usefulness is integrally formed when the making of flexible pipe 3, so, simple for production, can save production costs.
