Description

[Detailed description of the invention] [Industrial application field] This invention relates to a hole opening device for an electrolyte container for a vehicle battery. This invention relates to a container opening device.

[Conventional technology]

Conventionally, the MF battery for motorcycles and the electrolyte container are transported separately, so when in use, the electrolyte is injected into the battery from the container containing the electrolyte.
For example, an electrolyte container A as shown in FIG. 5 is used, and this electrolyte container A has a liquid chamber 5 with a liquid spout 6 at the bottom and an air inlet 7 at the top as sealed ports. , the number corresponding to the number of cells in the battery 8 (in this case, the number of six 1-cell/2-volt cells connected) is arranged in the same manner as each cell, and is composed as a whole. Each liquid chamber 5 of this electrolytic solution container A is filled with a known and ordinary electrolytic solution (not shown) in advance, and when this electrolytic solution is required, each of the liquid pouring ports of the electrolytic solution container A described above is used. 6 using a tool such as nippers or scissors, and then inserting each liquid outlet 6 into each liquid inlet 9 of the battery 8 to remove the air flow protruding from each upper part of the liquid chamber 5. By individually cutting the inlets 7 with the above-mentioned tools (nippers, scissors, etc.), the liquid inlet 9 is opened from each liquid outlet 6 at the bottom while atmospheric pressure is obtained in each liquid chamber 5. Each electrolytic solution is injected into the cell opening directly below each position through the opening.

[Problem that the invention attempts to solve]

Due to the above, conventionally, when pouring electrolyte from the electrolyte container A into the battery 8, the following problems occurred.

(1) When injecting the electrolyte in each liquid chamber 5 into the battery 8, the liquid spout 6 protrudes from the bottom of each liquid chamber 5.
A tool (for example, nippers, scissors, etc.) is required to individually cut the air inlets 7 protruding from each upper part, which is time-consuming and sometimes results in forgetting to cut.

(2) Furthermore, when the sealing ports 6 and 7 of the electrolyte container A are cut with a tool such as nippers or scissors, the electrolyte (dilute sulfuric acid) contained in each liquid chamber 5 may adhere to the tool, causing the tool to It rusted, which increased the wear rate of the tool.

[Means for solving problems]

This invention solves the problems of the prior art described above, and provides a hole opening device for the electrolyte container that allows for easy and quick injection of liquid from the electrolyte container into the battery without the need for tools. Our goal is to provide the following. The feature of this invention is that cylinders are formed on the support plate with the same number and arrangement of sealing ports at the upper and lower ends of the battery electrolyte container, and each cylinder has an individual liquid chamber in the electrolyte container at the center position. It consists of an upright hole piercing bar that pierces through the sealing openings formed at the upper and lower ends of each.

[Effect]

With the above configuration, when injecting liquid from the electrolyte container into the battery, each hole pierce of this hole holder is placed in contact with the lower liquid spout of the electrolyte container, and then When a pressing force is applied, each hole puncturer breaks through the sealed port at each position, so the unsealed liquid spout is inserted into each liquid inlet of the battery and communicated with the cell immediately below. At this point, each aperture piercer of the aperture device is brought into contact with the upper air inlet of the electrolyte container, and pressing force is again applied to the aperture device.
Each air inlet is opened at the same time to obtain atmospheric pressure in all liquid chambers, thereby easily and reliably injecting the electrolyte in all liquid chambers into the cells at each position of the battery at once. be able to. After the liquid is injected, by tightly fitting the hole opening device into the liquid injection port of the battery, the hole opening device can be used as a sealing stopper for the liquid opening of the battery.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 1 to 4, the opening device for the electrolyte container according to this invention is constructed as follows. That is, by molding the resin material, the top surface of the rectangular support plate 2 is provided with a battery electrolyte container A.
The same number and the same arrangement as the sealing ports 6 and 7 at the upper and lower ends (this is also the same number and the same arrangement as each liquid inlet 9 of the battery 8, and it is tightly fitted into the inner diameter of each liquid inlet 9 as a liquid inlet sealing plug. Each cylindrical body 3 is formed so as to have an outer diameter that allows for A cone-shaped hole puncture bar 4 that can be pierced by a puncture operation is installed in each of the sealing ports of the liquid spout 6 at the bottom and the air inlet 7 at the top. It is configured as a body retractor 1. Note that 10 indicates each liquid inlet 9 of the battery 8.
A cell (single cell) is placed directly below the battery 8 and is the main component of the battery 8. Further, 11 indicates that when each cylindrical body 3 of the hole opening device 1 is tightly fitted into each liquid inlet 9 of the battery 8 as a liquid inlet sealing plug, the support plate 2 of the hole opening device 1 is attached to the upper surface of the battery 8. This is a groove for fitting in the same plane as the

With the above-mentioned configuration, when injecting liquid into the battery 8 from the electrolytic solution container A, which is formed by filling and sealing the electrolytic solution into each liquid chamber 5 in advance, each of the aperture piercers 4 of the aperture device 1 is electrolyzed. When a pressing force is applied to the perforator 1 toward the liquid chamber 5 side while it is in contact with the lower liquid spout 6 of the liquid container A, each perforator 4 releases the liquid at each position. In order to break through the sealed opening of the outlet 6, each unsealed liquid spout 6 is inserted into each liquid inlet 9 of the battery 8. (See Figure 2) In this case, each liquid spout 6 communicates with each cell 10 immediately below it via the liquid inlet 9, but since each air inlet 7 at the top is in a sealed state, at this point No liquid is injected from inside the liquid chamber 5 yet. In this state, next, each aperture piercer 4 of the aperture device 1 is brought into contact with the upper air inlet 7 of the electrolyte container A, and the same as above is carried out again.
When a pressing force is applied to the opening device 1 toward the liquid chamber 5 side, the air inlets 7 of the electrolyte container A are opened all at once. (See Fig. 3) Therefore, atmospheric pressure is obtained in all the liquid chambers 5, which allows the electrolyte in all the liquid chambers 5 to be easily and reliably transferred into the cells 10 at each position of the battery 8 at once. can be injected into. After the liquid is injected as described above, by tightly fitting the opening device 1 into the liquid inlet 9 of the battery 8, the opening device 1 can function as a liquid port sealing plug for the battery 8.

[Effect of idea]

This idea consists of forming cylinders on a support plate, and at the center of each cylinder, a perforated protrusion is installed that penetrates the sealing openings formed at the upper and lower ends of each liquid chamber of the electrolyte container. It is characterized by the following. Therefore, when pouring liquid from the liquid chamber of the electrolyte container into the battery, the liquid can be poured easily and quickly by using this hole puncher without the need for any tools, thereby eliminating the hassle of using tools. It has the effect of eliminating the wear and tear of the sheath and the tool that occurs during use, and can also be used as a sealing plug that is a part of the battery.
