Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dust collection chamber cover and a pivot structure for a handle of a vacuum cleaner.

BACKGROUND ART Conventionally, this type of vacuum cleaner has a structure as shown in FIGS. 6 and 7. That is, a main body 1 of the vacuum cleaner is provided with a shaft 2, a dust collection chamber lid 4 with a bearing 3 rotatably fitted on this shaft 2, and further a dust collection chamber lid 4 with a bearing 3 rotatably fitted thereon.
A handle 5 is rotatably attached to the handle. This handle 5
The cross-sectional shape of is set to be square. When attaching the dust collection chamber cover 4 with the handle 5 attached to the main body 1,
In order to fit the bearing 3 onto the shaft 2, the main body 1 and the handle 5 are
A gap a is required between the two. The dust collection chamber lid 4
The angle of opening and closing is regulated by a locking portion provided on the main body 1.

Problems to be Solved by the Invention However, with such a configuration, since the gap a is required for the above-mentioned reason, the bearing 3 is likely to come off from the shaft 2, and the gap a causes problems such as poor appearance. It was hot.

SUMMARY OF THE INVENTION The present invention solves these conventional problems and provides a structure that prevents the bearing from coming off and that is easy to assemble.

Means for Solving the Problems In order to solve the above problems, the present invention provides a handle with a cross-sectional shape that is substantially triangular in shape and open downward. Furthermore, the locking portion that regulates the opening angle of the dust collection chamber lid is configured to be inclined.

Function As described above, in the present invention, the handle is configured in a triangular shape, so that elasticity is improved, and even if the gap between the main body and the handle is small, assembly is easy and it is difficult to come off. In addition, since the locking portion that locks the opening angle of the dust collection chamber lid is tilted, the bearing moves in the direction of the shaft, making it even more difficult for the bearing to come off.

Embodiment The embodiment will be described below with reference to FIGS. 1 to 5.

The main body 12 of the vacuum cleaner has a dust collection chamber 11 in front thereof. The dust collection chamber 11 has an open upper part and is closed with a dust collection chamber lid 13. This dust collection chamber lid 13
is a main body cover 14 that closes the rear opening of the main body 12;
The dust collection chamber 1 is rotated about a shaft 15 formed in the
Open and close 1. The entire handle 17 has a U-shape,
When not in use, it is housed in a recess 17a formed in the main body cover 14 and the dust collection chamber cover 13 so as to be continuous with each other, and is designed to be raised and lowered by rotating about the shaft 15.

More specifically, the shaft 15 is provided to protrude outward from the inner wall of the recess 17a, and by fitting cylindrical bearings 16 facing inward from both rear sides of the dust collection chamber cover 13, the shaft 15 collects the dust. The dust chamber lid 13 is pivotally supported, and the handle 17 has a substantially triangular cross section with an opening 19 at the bottom, and a shaft hole 1 provided in the inner piece thereof.
8 is externally fitted into a cylindrical bearing 16 of the dust collection chamber lid 13 to be pivotally supported.

20 is a locking part that regulates the opening angle of the dust collection chamber lid 13, and the contact surface 21 with the dust collection chamber lid 13 is connected to the shaft 1.
The structure is inclined with respect to 5.

The operation of this embodiment will be explained.

Connect the shaft hole 18 of the handle 17 to the bearing 16 of the dust collection chamber lid 13.
After that, the bearing 16 is fitted onto the shaft 15 of the main body cover 14. In this case, the handle 17
The gap d between the outer dimension b and the inner dimension c of the main body cover 14
Even if the handle 17 is made small, it can be easily assembled because the handle 17 has a triangular cross section and is elastic. Also, even after assembly, handle 1 from the place where the gap d is small.
7 does not move and does not come off easily.

Furthermore, when the dust collection chamber lid 13 is opened and rotated in the direction of the arrow D, the dust collection chamber lid 13 is pressed in the direction of the arrow E by the inclined contact surface 21 provided on the locking part 20, so that the shaft The bearing 16 does not come off from the bearing 15.

Effects of the Invention As described above, the present invention improves elasticity by making the cross-sectional shape of the handle triangular, so that it can be easily assembled even if the gap with the main body is small, and it is difficult to come off even after assembly.

In addition, because the contact surface of the locking part that regulates the opening angle of the dust collection chamber lid is sloped, if you try to open the dust collection chamber cover beyond the contact surface of the locking part,
Since the bearing of the dust collection chamber lid is pressed in the axial direction, the shaft will not come off.
