Description

Connecting structure of vacuum cleaner {A VACUUM CLEANER}

The present invention relates to a vacuum cleaner, and in particular, after the first insertion hole and the first coupling hole are formed in the vacuum cleaner body, the first insertion hole can be coupled to the connector and the first coupling hole can be coupled or separated. By combining the coupling member, it is possible to improve the breakage strength of the connection part of the vacuum cleaner main body and the connection pipe, and to obtain a beautiful appearance. It is about.

The coupling configuration of the connection tube coupled to the conventional vacuum cleaner is shown in Figures 1 and 2.

That is, the said structure is the connection pipe 2 protrudingly formed in the back part of the main body 1,

Through hole 3 formed in the connecting pipe (2),

A connecting pipe 11 inserted into and separated from the connecting pipe 2;

A spring lock device 12 is inserted into the through hole 3 formed in the connecting pipe 2 to fix the connecting pipe 11 to the connecting pipe 2.

Referring to the effects of the conventional configuration as described above are as follows.

First, in order to couple the connecting pipe 11 to the connecting pipe 2 of the main body 1, by pressing the spring lock device 12 is coupled to the connecting pipe 11 by hand, and then the connecting pipe (2) (11) is inserted.

Then, when the connector 11 is continuously inserted, the spring locking device 12 recessed in the connector 11 is elastically protruded at the instant of coinciding with the through hole 3 of the connector 2. The combination is made.

Therefore, the spring locking device 12 can be fixed to the main body 1 by the support force exerted while being coupled to the through-hole 3 of the connection pipe (2).

And, when separating the connecting pipe 11 from the main body 1, pressing the spring locking device 12 is inserted into the through hole (3) of the connecting pipe (2) and then the connecting pipe (11) Pull it out to make it easier to remove.

However, in the conventional coupling structure as described above, the connection part of the connection pipe 2 and the main body 1 to which the connection pipe 11 is coupled has a weak point.

That is, the connection part between the connection pipe 2 and the main body 1 must support the weight of the main body 1, so that the connection tube 2 having the same thickness as the main body 1 should be designed with high strength. ) Is integrally molded.

Therefore, the connection tube 2 often breaks during the use of the vacuum cleaner or while the connection tube 11 is coupled to or disconnected from the connection tube 2.

In order to reinforce the weak strength of the connection part as described above, there are also means for installing a plurality of ribs or thickening the connection part of the connection pipe 2 and the main body 1, but in this case the appearance of the vacuum cleaner It was not considered a preferable means because it might be inhibited.

In the conventional art, since the connecting pipe 11 is separated from the connecting pipe 2 of the main body 1 and detached from the connecting pipe 2, the spring locking device 12 is strongly pressed with a finger to separate and engage the handle. I also had a very uncomfortable problem.

The purpose of this article to solve and complement these conventional problems,

It can improve the breakage strength of the connection part of the vacuum cleaner main body and the connecting pipe, obtain the beautiful appearance, and provide the purpose of obtaining the convenience of separating and joining the connecting pipe to the main body.

In order to achieve the above object,

After forming the first insertion hole and the first coupling hole in the vacuum cleaner body, the first insertion hole is coupled to the connecting tube and the first coupling hole is coupled to the coupling member for coupling or detaching the connection purpose of the present purpose Will be achieved.

The coupling pipe 121 is coupled from the main body 101 by being coupled or separated by being inserted into or separated from the first through hole 105 of the first partition 104 and the coupling portion 122 of the coupling pipe 121. Or it is a configuration having a coupling member 131 coupled to the first coupling hole 103 in order to be separated.

In addition, the coupling member 131 is inserted into the coupling portion 122 formed in the first through hole 105 and the connection pipe 121 formed in the first partition 104 to allow the connection pipe 121 to be coupled. Coupling portion 132 for,

The coupling portion 132 is removed from the coupling portion 122 of the coupling pipe 121, the coupling pipe

A push piece 133 for easy separation of the 121 from the body 101,

Elastic portion connecting the coupling portion 132 and the wheat piece 133 in order to give elasticity to the wheat piece 133 to obtain a coupling operation and separation operation of the coupling portion 132 as necessary.

With 134,

The elastic part 134 was provided as a pressing piece 136 formed on the upper side of the coupling member 131 so that the user can easily press from the outside.

In addition, the elastic portion 134 is composed of a plurality of uneven bending surface 135.

Then, the coupling portion 132 and the pressing piece 133 to be detached from the coupling portion 122 of the connecting pipe 121 while the coupling portion 132 is smoothly raised by the pushing force of the pressing piece 133. ), The first inclined surface 137 and the second inclined surface 138 are formed to face each other. In addition, the first insertion hole 102 and the first communication hole in communication with each other in the main body 101 in order to further improve the breaking strength of the connecting portion and to more easily mount the connecting tube 121 and the coupling member 131 to the main body 101 A third insertion hole 106 is formed, and the second insertion hole 142 and the coupling member (2) into which the connecting pipe 121 can be inserted in the first insertion hole 102 and the third coupling hole 106 which are in communication with each other. A case 141 forming a second through hole 145 in the second partition 144 into which the second coupling hole 143 into which the 131 can be inserted and the coupling portion 132 of the coupling member 131 can be inserted. ) Was inserted and mounted.

The operation of this paper is as follows.

First, Figure 3 is an exploded perspective view of the first embodiment showing the coupling structure of the connection tube coupled to the vacuum cleaner of the present invention and Figure 4 is an enlarged cross-sectional view showing the main portion of the connection state of the connection tube, the main body 101 The first insertion hole 102 is formed directly in the structure to insert the connection pipe 121.

That is, insert the connecting tube 121 into the first insertion hole 102, the insertion portion 122 formed in the connecting tube 121 is directed so as to face the first coupling hole 103 of the main body 101 Let's do it.

In addition, the coupling member 131 coupled to the first through hole 105 formed in the first partition 104 between the first insertion hole 102 and the first coupling hole 103 by the first coupling hole 103. Coupling portion 132 of the) is waiting to be inwardly protruded.

When the engaging portion 132 is in contact with the end portion of the connecting tube 121 which is continuously inserted as described above, the state of closely contacting the outer circumferential surface of the connecting tube 121 is heard upward by the pushing force of the connecting tube 121.

It is enough to remove the connecting pipe 121 while pressing the pressing piece 136 of the coupling member 131 is coupled.

That is, by the pressing operation of the pressing piece 136, the elastic portion 134 formed of a plurality of uneven bent surface 135 is compressed and the compact piece by the above compression phenomenon

133 is advanced in the direction of the coupling portion (132).

In addition, the contact piece 133 continues to move forward to come into contact with the coupling part 132, and thus, the first inclination surface 132 of the coupling part 132 provided with the second inclined surface 138 formed on the contact piece 133 is opposed to each other. 137 pushes the coupling portion 132 is lifted from the coupling portion 122 of the coupling pipe 121 while the coupling portion 132 is lifted in the direction of the first through hole 105 of the first partition wall 104. ) Can be easily separated.

Therefore, it is possible to obtain the convenience of separating and coupling the connection pipe 121 to the main body 101.
