Abstract
The present invention relates to a sealing structure of hose connecting device for vacuum dust collector for tightly closing connection position of handle tube and hose. The structure of said invented hose connecting device is characterized by that the left-right integrated extended arranged connecting rings with elastic locking jaws and inserted into the frond end of the hose tube, and the elastic locking jaws of the above-mentioned connecting rings are inserted and passed through the left-right locking holes of the hose connecting part of the handle tube, and are locked tightly so as to make the connecting hole of the front end of the hose connected with handle tube expand, integratively form internal end jaw in its expanded portion interior and integratively form internal tube in the hose connecting part interior of handle tube.
Description
Technical field
The present invention relates to a kind of hermetically-sealed construction of hose connector of vacuum cleaner, its structure is, make the connector expansion of the flexible pipe front end that is connected with the handle tube of vacuum cleaner, form the inner blade of a sword along this expansion, flexible pipe linkage section inside at handle tube forms interior pipe, the expansion front end of above-mentioned flexible pipe inserts in the insertion groove that is formed by interior pipe, the inner blade of a sword and the inner tube portion of flexible pipe closely link together simultaneously, thereby flexible pipe is coupled together, and the connecting portion of handle tube and flexible pipe is by closely airtight thus.
Background technology
Generally, in making vacuum cleaner usefulness flexible pipe and handle tube be connected, on the connector of the flexible pipe linkage section of handle tube and flexible pipe front end, form threaded portion in correspondence with each other respectively, thereby carry out mutual being threaded, other method is used other attaching parts such as attachment screw in addition and is assembled together.
But, there is following problem in above-mentioned screw connection structure, promptly the state of being threaded is easy to relax, so must carry out fastening at any time, very loaded down with trivial details in the operation, when using other attaching parts in order to address this problem simultaneously, must a plurality of screws are fastening singly, fastening operation is also very loaded down with trivial details, and the result causes the poor efficiency of use.
In addition, in order to address the above problem, a kind of jockey is developed, the connecting ring 3 that this jockey will have elastic atresia's blade of a sword 3a inserts in the flexible pipe 1, elastic atresia's blade of a sword 3a of this connecting ring 3 embeds the obturator hernia 4 of the flexible pipe linkage section 2a that passes handle tube 2, thereby flexible pipe 1 links together with handle tube 2.This structure can obtain following effect, and is promptly simple in structure, and the connection of flexible pipe 1 and lock out operation are easy, can keep stable connection status simultaneously.
But, this device only makes flexible pipe 1 be connected with handle tube 2 by connecting ring 3, its connection status defective tightness, so in the process of inhaled air by the inside of handle tube 2 and flexible pipe 1, portion of air is leaked to the outside by the gap of coupling part situation can take place, its result causes along with subtracting a little less than the air inhalation power, and the performance of dust catcher descends.
Summary of the invention
The hermetically-sealed construction that the purpose of this invention is to provide a kind of hose connector of vacuum cleaner, in vacuum cleaner is used flexible pipe and handle tube is connected, this is simple in structure, and its connection status is stable simultaneously, so can prevent to suck air well to external leakage.
Description of drawings
Fig. 1 is the broken section exploded perspective view of hermetically-sealed construction of the present invention.
Fig. 2 is the assembling view of hermetically-sealed construction of the present invention.
Fig. 3 is the amplification view of the major part of hermetically-sealed construction of the present invention.
The specific embodiment
Following with reference to accompanying drawing, technology contents of the present invention is elaborated.
The hermetically-sealed construction of hose connector of vacuum cleaner of the present invention is, extend the front end that the connecting ring 3 that is provided with elastic atresia's blade of a sword 3a inserts flexible pipe 1 left-right integratedly, elastic atresia's blade of a sword 3a of above-mentioned connecting ring 3 embeds the obturator hernia 4 about the flexible pipe linkage section 2a that passes handle tube 2 and locks, it is characterized in that
Make the connector 1a expansion of the front end of the flexible pipe 1 that is connected with handle tube 2, in its expansion, form inner blade of a sword 1b, pipe 2b in the flexible pipe linkage section 2a inside of handle tube 2 forms, the connector 1a of the front end that the quilt of flexible pipe 1 is expanded inserts the insertion groove 2c that is formed by interior pipe 2b, and the front end of above-mentioned inner blade of a sword 1b of while and interior pipe 2b closely links together.
In the accompanying drawings, the flexible pipe linkage section 2a that label 2d is illustrated in handle tube 2 goes up the inclined plane that forms, so that the embedding of elastic atresia's blade of a sword 3a and obturator hernia 4 action is carried out smoothly, label 3b represents the complications support blade of a sword of connecting ring 3.
As mentioned above, the flexible pipe linkage section 2a that the present invention uses elastic atresia's blade of a sword 3a of connecting ring 3 to be embedded in handle tube 2 goes up the obturator hernia 4 that forms and embeds the jockey of locking, and handle tube 2 and flexible pipe 1 are linked together.
At this moment, the connection 1a of front end of flexible pipe 1 that is inserted into the insertion groove of handle tube 2 is expanded, and forms inner blade of a sword 1b simultaneously in the junction, and on the pipe 2b, the connecting portion of flexible pipe 1 and handle tube 2 was by tight seal in therefore above-mentioned inner blade of a sword 1b closely was connected.
As mentioned above, the present invention uses the simple jockey of a kind of like this assembling, be to give prominence to the leading section outside that the connecting ring 3 that is provided with elastic atresia's blade of a sword 3a inserts flexible pipe 1 left-right integratedly, on the flexible pipe linkage section 2a of handle tube 2, form to make and state elastic atresia's blade of a sword 3a and embed wherein and the obturator hernia 4 of locking, thereby flexible pipe 1 and handle tube 2 are together with each other, because handle tube 2 and flexible pipe 1 link together, so this moment, inner blade of a sword 1b was integrally formed in the connector 1a of the front end of flexible pipe 1, in the connector 1a insertion handle tube 2 and the insertion groove 2c between the interior pipe 2b of above-mentioned front end, inner blade of a sword 1b by on the front end of pipe 2b in closely being connected, has kept airtight closely power by the fastening force of connecting ring 3 simultaneously.
Therefore, when vacuum cleaner carried out the air suction action, therefore the suction air of the connecting portion by flexible pipe 1 and handle tube 2 will not guarantee the very strong inhalation power of vacuum cleaner to external leakage.
In addition, because in flexible pipe 1 shaping manufacture process, the connector 1a of flexible pipe 1 front end and inner blade of a sword 1b are integrally formed,, can accurately make simultaneously, thereby can reach the effect of saving manufacturing expense, reduction manufacturing cost so it is made simply.
