Abstract

PURPOSE: To prevent an opening/closing cover from coming out of position when the cover is subjected to shocks, etc., from the outside and to make the cover to be removed by only sliding it by coupling groove-like projections with projecting sections protruded outward after sliding and putting small semicircular recessed sections on small semicircular projecting sections when the cover is put on a dry cell case. CONSTITUTION: Small semicircular projecting sections 36 are respectively provided to projecting sections 22 protruded outward on a dry cell case 20 and small semicircular recessed sections 37 are respectively provided to groove-like projections 23 formed on an opening/closing cover 21 so that the projections 23 can be respectively engaged with the projecting sections 22. When the cover 21 is put on the case 20, therefore, the cover 21 is surely coupled with the case 20, because the recessed sections 37 are put on the projecting sections 36. When the cover 21 is strongly pulled after sliding, the cover 21 can be easily removed from the case 20 at the time of removing the cover 21 from the case 20.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to FIGS.
This will be described in detail with reference to FIG. FIG. 1 is an exploded perspective view of a dry battery housing according to an embodiment, FIG. 2 is a view showing a combined state of a dry battery case and an opening / closing lid, FIG. 3 is a vertical cross-sectional view of the dry battery housing of FIG. 2, and FIG. Figure 3 shows a lateral cross section of the dry cell housing of Figure 1;

In FIG. 1, three outwardly convex portions 22 are provided on each of the left and right sides of the dry battery case 20 in the vertical direction of the opening. Three groove-shaped projections 23 are provided on the left and right sides of the opening / closing lid 21 in the vertical direction of the opening, respectively, at positions corresponding to the outwardly projecting portions 22 when the battery case 20 and the opening / closing lid 21 are coupled. There is.

When the opening / closing lid 21 is attached to the dry battery case 20, first, the outwardly facing convex portion 22 and the groove-like protrusion 23 are aligned with each other by the marker 14 for aligning them. Thereafter, as shown in FIG. 2, the open / close lid 21 is slid in the direction of the arrow Y, so that the outward convex portion 22
And the groove-shaped projection 23 are fitted to each other, and the dry battery case 20 and the opening / closing lid 21 are connected.

Further, in the lateral direction of the dry battery case 20, two fitting holes 25 are provided on the outside of the upper surface, and two fitting holes 26 are provided on the inside of the bottom surface. The opening / closing lid 21 is provided with two key-like portions 29 each having a convex portion 27 for engaging with the fitting hole 25 at two positions on the upper portion. Further, two vertical ribs 34 having a convex portion 28 for engaging with the fitting hole 26 are provided in the lower portion.

Accordingly, when the opening / closing lid 21 is connected to the dry battery case 20, the convex portion 27 is fitted in the fitting hole 25 and the convex portion 28 is fitted in the fitting hole 26, so that the dry battery housing is laterally mounted. Also in the above, both are fixedly coupled on the upper and lower sides.

Thus, the dry battery case 20 and the opening / closing lid 2
In the state in which 1 and 7 are finally coupled, as described above, not only are they coupled at six positions by the outward-facing convex portions 22 and the groove-shaped protrusions 23 on the left and right sides in the vertical direction of the dry battery housing, but also in the lateral direction. Also, the fitting hole 25, the fitting hole 26, and the convex portion 2 of the key-like portion 29 that engages with them, respectively.
7 and the protrusions 28 of the vertical ribs 34 connect at four places, so that the dry battery case 20 and the open / close lid 21 are firmly connected.

Further, each of the outward convex portions 22 provided on the dry battery case 20 is provided with a semicircular small convex portion 36, and the opening / closing lid 21 for engaging with the outward convex portions 22. Each of the groove-shaped projections 23 provided on the above is provided with a semicircular small recess 37. Therefore, when the opening / closing lid 21 is coupled to the dry battery case 20, the semicircular small convex portion 36 is fitted in the semicircular small concave portion 37, and the dry battery case 20
And the opening / closing lid 21 are securely coupled.

To remove the opening / closing lid 21 from the dry battery case 20, the opening / closing lid 21 can be easily removed only by strongly pulling the opening / closing lid 21 in the direction opposite to the arrow Y direction shown in FIG.

As shown in FIGS. 1 and 3, the inner surface of the dry battery case 20 and the inner surface of the opening / closing lid 21 prevent the plurality of dry batteries 32A and 32B housed therein from being displaced or moved. In order to increase the strength of the dry battery case 20 and the opening / closing lid 21, a plurality of lateral ribs 31 are provided. Among them, the lateral rib 31 provided on the opening / closing lid 21 is integrally provided with a slope portion 33. It is provided.

In FIG. 3, when the opening / closing lid 21 is removed from the dry battery case 20, the sloped portion 33 is the opening / closing lid 21.
Since it moves upward with respect to the drawing, the slope part 3
3 contacts the side surface of the dry battery 32A. Further openable lid 2
1 is moved upward, the slope portion 33 becomes a dry battery 32A.
By the reaction force of the force that presses,
It moves in the direction of detaching from the dry battery case 20 (the direction of removal) together with 1. That is, the removal operation of the opening / closing lid 21 is assisted by the slope portion 33.

In the above embodiment, the dry battery case 20 is used.
Also, three outwardly projecting portions 22 and groove-like projections 23 are provided on each of the left and right side surfaces of the opening / closing lid 21, and two fitting holes and two projecting portions are provided on each of the upper and lower surfaces, but the number is not limited to this. Needless to say, the number of installations is determined by the size of the dry battery housing.

It is not necessary to provide the semicircular small convex portions 36 and the semicircular small concave portions 37 on all the outward convex portions 22 and the groove-shaped projections 23, but it is sufficient to provide them in one or two places.

[0025]

As can be understood from the above description, according to the dry battery housing structure of the present invention, one or more outwardly projecting portions and groove-like projections are provided on the longitudinal side surface of the dry battery housing, and the dry battery housing is provided with the lateral direction. Since one or more fitting holes and protrusions are provided on the front side, and semi-circular small convex portions and semi-circular small concave portions are further provided on the outward convex portion and the groove-shaped protrusion, it is possible to prevent external impact or the like. Thus, the opening / closing lid can be prevented from coming off, and the opening / closing lid can be easily removed from the dry battery case only by the sliding operation of the opening / closing lid.

Further, since the removal of the opening / closing lid is assisted by the inclined surface portion of the lateral ribs provided inside the opening / closing lid, there is an effect that the removal of the opening / closing lid becomes easier.
