Description

[Detailed description of the invention] The present invention is a buckle device for attaching and detaching the main body and the dust collection box in a vacuum cleaner, in which the main body and the dust collection box are configured to be detachable, and a handle is provided at the upper part of the divided part. It is related to.

Conventionally, most of these types of vacuum cleaners have a handle at the top center, so the buckle is placed on the rear top surface of the main body. It was very troublesome as I had to operate the buckle which was separated from the handle. In addition, since the buckle is provided on the top of the main body, if you accidentally press the buckle while transporting it, or if you are holding an attachment such as an extension tube, you will not be able to press the buckle with the attachment. If this happens frequently and the hand is fixed to the dust collection box side, the main unit containing the heavy electric blower may fall, injuring the user or damaging the floor or the vacuum cleaner itself. There were other problems.

The present invention solves the above problems and provides a vacuum cleaner buckle device that is easy to use and highly safe. Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 1 shows the overall structure of a vacuum cleaner according to an embodiment of the present invention, in which 1 indicates an electric blower 2.
3 is a dust collection box containing a filter 4, and both of them are configured to be detachable. Reference numeral 5 denotes a handle for the vacuum cleaner, and a buckle 6 for attaching and detaching the main body 1 and the dust collection box 3 is disposed inside the handle. It consists of hook parts 9, etc. In addition, 1
0 is the intake port to which the hose is connected, 11 is the front wheel, 1
2 is the rear wheel.

FIG. 2 is a detailed cross-sectional view of the buckle 6, in which the operating button 7 is arranged on the upper surface of the approximately central part of the buckle 5, and the lower part of the operating button 7 is provided with a spring 13 that always urges the operating button 7 upward. is provided.

are arranged, and on these guide bosses 14a, 14b,
Guide cylinder 15a, 1 integrally formed with operation button 7
5b is slidably attached.

Reference numeral 8 denotes left and right guide ribs, and these ribs prevent looseness in the vicinity of the buckle hook part 9, so that the main body 1
The slope 8a of the main body hook 8 and the slope 9a of the buckle hook 9 are inserted when connecting the dust collection box 3 and the dust collection box 3.
This force acts reliably, causing the buckle 6 to move up and down and the hooks 8 and 9 to engage with each other. Reference numeral 19 denotes a handle cover, which is attached to the guide boss 14a by screws 20.
At the same time, the end of the handle engages with a hook 21 provided on the main body 1 and is attached to the handle 5. Note that 22 is a positioning pin.

In this embodiment configured as described above, the guide mechanism is provided before and after the operation button 7, so when the operation button 7 is pressed, the entire buckle 6 is smoothly lowered, and the buckle hook part 9 is connected to the main body side hook part. 8, the main body 1 and the dust collection box 3 can be separated. In addition, since the operation button 7 is placed on the upper surface of the central part of the hand 5, the operation button 7 is in the palm of the hand while the vacuum cleaner is being carried, so it is extremely safe as there is no possibility of accidentally pressing it. Moreover, when in use, the operation part is provided on the handle 5, so the operability is very good. Furthermore, since the guide boss 14a is also used for attaching the handle cover 19,
It does not require a separate mounting boss and can be constructed at low cost.

As explained above, according to the present invention, it is possible to provide a buckle device that is highly safe, reliable, and easy to use, and has great practical effects.
