Abstract

PURPOSE:To enable one same box to be applicab to various kinds of dry batteries by attaching a plurality of guide rods to a dry battery storage part and guiding and holding a slide plate provided with other end side contact members by means of the guide rods. CONSTITUTION:One end side contact members 3, 3 are arranged on one end side part wall of a box main body 10 and a dry battery storage part 8 is formed in the side wall 11 in the main body 10. On both sides of the storage part 8, guide rods 1, 1 are stably assembled between the side wall 11 and the other end side wall 12 by using nuts and washers. A slide plate 2 is movably inserted around the rods 1, 1 and the other end side contact members 4, 4 are attached to the plate 2. Cylindrical compressed elastic materials 7 are incorporated between the plate 2 and the side wall 12 in the main body 10 in such a state as being inserted by the rods 1. Respective dry batteries from a size D to a size AA or a size AAA are thus appropriately set in one box so as to enable a test and measurement and its handling can be facilitated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry battery box suitable for teaching materials and the like, in which dry batteries having different lengths such as AA to AA or AAA are properly and stably accommodated and set in the same dry battery box. The purpose of the present invention is to provide a dry battery box which can be tested or used.

[0002]

2. Description of the Related Art In the case of learning about dry batteries, testing, and measuring, it is necessary to set them in a housing, electrically connect them, and energize them. The length is different up to AAA, and it is common for classmates to bring different things to each other when studying and experimenting at schools, etc. It is necessary to prepare different boxes.

[0003]

As described above, it is not easy to prepare separate boxes for dry batteries having different lengths from AA to AA. Especially in schools, etc., it is necessary to train a large number of children at the same time. Not only is the cost high, but there are significant disadvantages in storage and management.

Therefore, in actual learning, it is often necessary to carry out an experiment in a box that does not exactly match the dry cell, and the experiment is carried out while setting and holding the dry cell in the box. It is inconvenient and unavoidable, such as impeding accurate test measurement.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been studied to solve the above-mentioned problems in the prior art, and a slide plate using a cylindrical elastic material as a contact member for one end side of a dry battery, and the slide plate. By adopting a guide rod for guiding the battery, it has succeeded in promptly responding to any dry cell with the same box, and is as follows.

(1) A plurality of guide rods are attached to a dry battery accommodating portion in which one end side contact member is disposed on one end side wall, and a slide plate in which the other end side contact member is disposed is guided and held by these guide rods. A dry battery box suitable for a teaching material or the like, characterized in that a guide tube supports a compression cylindrical elastic material that presses the slide plate.

(2) The teaching material as described in the above item (1), characterized in that the one end side contact member and the other end side contact member are respectively connected with cords which can be connected to each other or separately. Suitable for dry battery box.

[0008]

Operation: A plurality of guide rods are attached to the dry battery accommodating portion in which one end side contact member is disposed on one end side wall, and a slide plate in which the other end side contact member is disposed is guided and held by these guide rods. Slide the slide plate on which the other end side contact member is arranged with respect to the dry battery accommodating section in which the contact member is arranged, and set dry cells of different lengths such as AA to AA in the same box as appropriate. Test and measure.

As described above, since the plurality of guide rods attached to the dry battery accommodating portion support the compression cylindrical elastic member for elastically pressing the slide plate, the compression elastic action of the compression cylindrical elastic member is exerted on the slide plate. Any of the dry cells that have been supplied and have different lengths as described above is held in the uniform pressure contact energized state between the contact members. A particularly preferable compression tubular elastic material is a coil spring.

By connecting the one end side contact member and the other end side contact member to each other or connecting the cords which can be respectively connected to each other, the dry batteries accommodated in the dry battery accommodating portion as described above are directly or It is possible to connect them in an appropriate connection relationship in parallel and perform test measurement under each condition.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, one end side contact members 3, 3 are arranged on one end side wall 11 of a box body 10. A dry battery storage portion 8 is formed in the one end side wall 11 in the box body 10, and guide rods 1, 1 are provided on both sides of the dry battery storage portion 8 with the other end side wall 12 by using nuts and washers. It is assembled in a stable manner.

The slide plate 2 is movably inserted into the guide rods 1 and 1 as described above, the other end side contact members 4 and 4 are attached to the slide plate 2, and the slide plate 2 is also attached. Compressed tubular elastic members 7 are assembled between the side wall 12 and the other side wall 12 of the box body 10 by the guide rods 1, respectively.

The contact members 3, 3 and 4, as described above,
The cords 5, 5 or 6, 6 are connected to the cords 4, respectively, but the tips of the cords 5, 5, 6, 6 are peeled off so that they can be electrically connected. The connection relationship between the cords 5, 5, 6 and 6 is as shown in FIG. 2 separately. By connecting the cords 5 and 5 on one side and pulling them out from the cords 6 and 6 on the other side as shown in FIG. Batteries 9 and 9 through the contact members 3, 3, 4, and 4
Are connected in series, and as shown in FIG.
It is clear that 5 and the cords 6, 6 are connected in parallel by connecting and withdrawing them.

In the present invention, the dry batteries AA to AA or AAA as described above differ not only in the height but also in the diameter of the dry battery, but the dry battery 9 having such a different diameter is used.
It is clear that in order to set the battery in the dry battery accommodating portion 8 in a stable state, an interposition of an appropriate thickness may be interposed between both dry batteries 9 in cases other than the large-sized AA dry battery. However, it is possible to form a stable and accurate setting state.

[0015]

According to the present invention as described above, various dry batteries ranging from AA to AA or AAA can be appropriately set and tested and measured in one box. It is easy to handle, and it is possible to easily install and remove the dry battery by simply moving the slide plate, and it is possible to accurately perform various test measurements including series and parallel connection relationships. It is an invention that has a large effect.
