Description

[Detailed description of the invention] Industrial applications The present invention relates to an engagement device used in various types of equipment.

Structure of a conventional example and its problems Hereinafter, a conventional engaging device will be explained using a drawing, taking a small vacuum cleaner as an example.

In FIG. 1, 1 is the body of a small vacuum cleaner, 2 is a motor installed inside the body 1 and drives a fan 3, and 4
1 is a handle provided on the body 1, 5 is a filter for collecting dust in the dust-containing air sucked by the fan 3, and 6 is a dust box detachably attached to the body 1 with screws 7.

However, according to the above configuration, when discarding dust, the screw 7
After removing the dust box 6, I had to remove the dust and throw away the dust, which was a lot of work.

FIG. 2 shows another conventional example, in which the same members as in FIG. 1 are given the same numbers. In FIG. 2, reference numeral 8 indicates an engaging portion provided on the body 1, and reference numeral 9 indicates an opening provided at a location corresponding to the engaging portion 8 of the dust box 6.
The dust box 6 was attached to the body 1 by engaging the engaging portion 8 with the holder. Further, the dust box 6 was removed from the body 1 by pushing in the retaining part 8.

However, when removing the dust box 6, use your finger to remove the engaging part 8.
There is a drawback that a displacement occurs between the engaging portion 8 and the dust box 6 due to pressing, and a finger may be caught between the opening 9 and the retaining portion 8.

OBJECTS OF THE INVENTION In view of the above-mentioned problems, the present invention provides a locking device that is easy to use.

Structure of the Invention The retaining device of the present invention includes a protrusion provided in the retaining portion having elasticity,
A locking hole for locking the protrusion is provided in the engaged portion, a suppressing portion having elasticity is provided on one side of the locking hole, and a suppressed portion is provided in the engaging portion facing the suppressing portion. With this configuration, the suppressor can be easily removed by simply pushing the suppressor, making it very convenient to use.

DESCRIPTION OF EMBODIMENTS Hereinafter, a case in which an embodiment of the present invention is applied to a small vacuum cleaner will be described with reference to FIGS. 3, 4, and 6.

Note that the same numbers are given to the same members as in the conventional example.

1o is an elastic engagement portion provided on the body 1, 11 is a protrusion provided on the engagement portion 10, and 12 is provided on the dust box 6 facing the protrusion 11 to lock the protrusion 11. A locking hole 13 is formed by making a notch 14 from one side of the locking hole 12, and a pressing part 15 is formed integrally with the dust box 6 to provide elasticity. The provided pressed portion 16 is a locking portion of a fitting type provided on the back side of the suppressing portion of the dust box 6.

With the above configuration, when the user removes the dust box 6 from the body 1, when the user presses the suppressing part 13 with his or her finger, the suppressing part 13 does not press the pressed part 16 of the engaging part 10 located on the back side. The pressed portion 15 is pressed by the protrusion 11 that is integrated with it.
is pushed, and as a result, the protrusion 11 comes off from the locking hole 12 of the dust box 6.

The dust box 6 can be easily removed from the body 1 by simply pressing the pressing part 13. Further, since the suppressing part 13 is provided integrally with the dust box 6, there is no operational deviation around the suppressing part 13, and there is no chance of fingers being caught.

Effects of the Invention As is clear from the description of the above embodiments, according to the locking device of the present invention, the engaged portion is provided with a pressing portion and the locking hole, and the engaging portion is provided with a pressed portion that is pressed by the pressing portion. By providing a protrusion that is locked in the locking hole, the locking can be easily released by simply pushing the suppressing part, and furthermore, there is no operational misalignment between the pressing part and the surrounding parts. Since there is no risk of pinching of fingers or skin, it is extremely convenient to use.
