Description

本発明は、バッテリー液補充器に関し、より詳しくは、車両用バッテリーの液量を確認して補充するためのバッテリー液補充器に関する。   The present invention relates to a battery liquid replenisher, and more particularly to a battery liquid replenisher for checking and replenishing the amount of liquid in a vehicle battery.

車両用バッテリーの液量確認を容易にして、バッテリー液の補充作業を迅速に行うためのバッテリー液補充器が、従来から知られている。例えば、特許文献１には、図６に示すように、漏斗状部５１および円筒部５２を備えるガイド５３と、指示棒５４の下端部に固定されたフロート５５とを備え、漏斗状部５１に設けられた支持部材５６により指示棒５４が上下動可能に支持された液量検知部材５０が開示されている。   2. Description of the Related Art Conventionally, a battery liquid replenisher for facilitating the confirmation of the amount of liquid in a vehicle battery and quickly replenishing the battery liquid has been known. For example, as shown in FIG. 6, Patent Document 1 includes a guide 53 including a funnel-shaped portion 51 and a cylindrical portion 52, and a float 55 fixed to the lower end portion of the indicator rod 54. A liquid amount detecting member 50 is disclosed in which an indicating rod 54 is supported by a provided support member 56 so as to be movable up and down.

この液量検知部材５０は、バッテリー本体６０の注入孔６１に円筒部５２を嵌合することにより、フロート５５がバッテリー液の液面６２に浮かんだ状態になるので、液面６２の高さを指示棒５４の目盛５４ａ，５４ｂで確認しながら、漏斗状部５１から円筒部５２を介してバッテリー本体６０内にバッテリー液を補充することができる。液面６２が最大高さまで上昇すると、円筒部５２の下端に設けられたシール部材５７にフロート５５が当接し、バッテリー液の供給流路が閉鎖される。   Since the float 55 floats on the liquid level 62 of the battery liquid by fitting the cylindrical portion 52 into the injection hole 61 of the battery body 60, the liquid level detection member 50 increases the height of the liquid level 62. The battery liquid can be replenished into the battery body 60 from the funnel-shaped portion 51 through the cylindrical portion 52 while checking with the scales 54a and 54b of the indicating rod 54. When the liquid level 62 rises to the maximum height, the float 55 comes into contact with the seal member 57 provided at the lower end of the cylindrical portion 52, and the battery liquid supply channel is closed.

特開２００６−２８６２５３号公報JP 2006-286253 A

ところが、上記従来の液量検知部材５０は、円筒部５２がバッテリー本体６０の内部に突出するため、バッテリー液の補充によりバッテリー本体６０内で液面が揺れたり液はねが生じたりすると、円筒部５２の外周面にバッテリー液が付着するおそれがあった。このため、作業後にバッテリー本体６０から液量検知部材５０を引き上げると、円筒部５２やフロート５５に付着したバッテリー液が手や衣服などに飛び散るおそれがあり、取扱性が悪いという問題があった。   However, since the cylindrical portion 52 protrudes into the battery body 60, the conventional liquid amount detection member 50 has a cylindrical shape when the liquid surface shakes or splashes in the battery body 60 due to replenishment of the battery liquid. There was a risk that the battery liquid would adhere to the outer peripheral surface of the portion 52. For this reason, when the liquid amount detection member 50 is pulled up from the battery body 60 after the work, there is a possibility that the battery liquid adhering to the cylindrical portion 52 or the float 55 may be scattered in a hand, clothes, etc., resulting in poor handling.

そこで、本発明は、作業性および取扱性に優れるバッテリー液補充器の提供を目的とする。   Therefore, an object of the present invention is to provide a battery liquid replenisher excellent in workability and handleability.

本発明の前記目的は、中空の外筒と、前記外筒内に液補充用の隙間をあけて支持された中空の内筒と、前記内筒に上下動可能に挿通された棒状体と、前記内筒から突出する前記棒状体の下部に固定されたフロートとを備え、車両用バッテリーの液口から挿入した前記フロートをバッテリー液の液面に浮かべたときの前記棒状体の高さからバッテリー液の液量を検出して、前記外筒の上部からバッテリー液を補充することができるバッテリー液補充器であって、前記外筒は、筒本体の下端から突出して前記液口に嵌合可能なリング状の嵌合部を備えており、前記嵌合部は、外部に露出する外周面の全体が前記液口の内周面に密着すると共に、前記フロートの全体を前記外筒内に収容可能に構成されているバッテリー液補充器により達成される。   The object of the present invention is to provide a hollow outer cylinder, a hollow inner cylinder supported with a liquid replenishment gap in the outer cylinder, and a rod-like body inserted through the inner cylinder so as to be movable up and down. A battery fixed from the height of the rod-shaped body when the float inserted from the liquid port of the vehicle battery floats on the liquid surface of the battery liquid. A battery liquid replenisher capable of detecting the amount of liquid and replenishing battery liquid from the upper part of the outer cylinder, and the outer cylinder protrudes from the lower end of the cylinder body and can be fitted into the liquid port A ring-shaped fitting part, and the fitting part has the entire outer peripheral surface exposed to the outside closely adhered to the inner peripheral surface of the liquid port, and the entire float is accommodated in the outer cylinder. This is achieved by a battery fluid replenisher that can be configured.

このバッテリー液補充器は、前記嵌合部に着脱可能に外嵌されて前記外筒の下端開口を覆うキャップを更に備えることが好ましい。   The battery liquid replenisher preferably further includes a cap that is detachably fitted to the fitting portion and covers a lower end opening of the outer cylinder.

本発明によれば、作業性および取扱性に優れるバッテリー液補充器を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the battery liquid replenisher excellent in workability | operativity and handleability can be provided.

以下、本発明の実施の形態について、添付図面を参照して説明する。図１は、本発明の一実施形態に係るバッテリー液補充器の斜視図である。図１に示すように、バッテリー液補充器１は、外筒２と、外筒２の内部に支持された内筒４と、内筒４に挿入された棒状体６と、棒状体６に取り付けられたフロート８とを備えている。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a battery liquid replenisher according to an embodiment of the present invention. As shown in FIG. 1, the battery liquid replenisher 1 is attached to the outer cylinder 2, the inner cylinder 4 supported inside the outer cylinder 2, the rod-like body 6 inserted into the inner cylinder 4, and the rod-like body 6. The float 8 is provided.

外筒２は、円筒状の筒本体２ａと、筒本体２ａの下端から突出するリング状の嵌合部２ｂと、筒本体２ａの上部から側方に張り出すように形成された注入部２ｃとを備えている。嵌合部２ｂは、後述するバッテリーの液口に挿入されて嵌合されるように、この液口の口径と略同じ外径を有している。   The outer tube 2 includes a cylindrical tube body 2a, a ring-shaped fitting portion 2b protruding from the lower end of the tube body 2a, and an injection portion 2c formed so as to protrude laterally from the upper portion of the tube body 2a. It has. The fitting portion 2b has an outer diameter that is substantially the same as the diameter of the liquid port so that the fitting portion 2b is inserted into and fitted into the liquid port of the battery described later.

内筒４は、外周面と外筒２の内周面との間に隙間が生じるように、支持部３によって支持されている。外筒２と内筒４との間に形成される隙間は、注入部２ｃから外筒２内に注入されたバッテリー液がスムーズに通過する程度の大きさであることが好ましい。   The inner cylinder 4 is supported by the support portion 3 so that a gap is generated between the outer peripheral surface and the inner peripheral surface of the outer cylinder 2. It is preferable that the gap formed between the outer cylinder 2 and the inner cylinder 4 has such a size that the battery liquid injected from the injection portion 2c into the outer cylinder 2 passes smoothly.

棒状体６は、中実または中空のいずれであってもよく、例えば、ポリカーボネート樹脂等からなる軽量パイプからなる。棒状体６は、内筒４に上下動可能に挿入されており、内筒４の上端および下端からの突出長さを変化させることができる。棒状体６の外周面には目盛部６ａが形成されており、内筒４の上端から突出して露出する棒状体６の目盛部６ａを目視することにより、内筒４に対する棒状体６の相対位置を把握することができる。目盛部６ａは、単一のラインで表示する以外に、複数のラインや複数色による色分け等であってもよい。   The rod-like body 6 may be either solid or hollow, and is made of a lightweight pipe made of polycarbonate resin or the like, for example. The rod-like body 6 is inserted into the inner cylinder 4 so as to be movable up and down, and the protruding length from the upper end and the lower end of the inner cylinder 4 can be changed. A scale portion 6 a is formed on the outer peripheral surface of the rod-like body 6, and the relative position of the rod-like body 6 with respect to the inner tube 4 by visually observing the scale portion 6 a of the rod-like body 6 that protrudes from the upper end of the inner tube 4 and is exposed Can be grasped. The scale part 6a may be color-coded by a plurality of lines or a plurality of colors in addition to displaying with a single line.

フロート８は、バッテリー液の液面に浮かぶように、例えば合成樹脂からなる発泡体や中空体等から形成され、内筒４から突出する棒状体６の下端に固定される。フロート８の形状は特に限定されないが、例えば球体にすることができる。   The float 8 is formed of, for example, a foam or hollow body made of synthetic resin so as to float on the liquid surface of the battery liquid, and is fixed to the lower end of the rod-like body 6 protruding from the inner cylinder 4. The shape of the float 8 is not particularly limited, but may be a sphere, for example.

上記の構成を備えるバッテリー液補充器１は、図２に示すように、車両用バッテリー２０の上蓋２２に複数形成された液口２４に対して、液口栓（図示せず）を取り外した後に嵌合部２ｂを嵌合させる。これにより、筒本体２ａの下端面が上蓋２２の上面に当接し、外筒２が起立保持される。この状態で外筒２の上部からバッテリー液を注入することにより、車両用バッテリー２０にバッテリー液を補充することができる。   As shown in FIG. 2, the battery liquid replenisher 1 having the above-described configuration has a liquid plug (not shown) removed from the liquid ports 24 formed on the upper cover 22 of the vehicle battery 20. The fitting part 2b is fitted. Thereby, the lower end surface of the cylinder main body 2a abuts on the upper surface of the upper lid 22, and the outer cylinder 2 is held upright. In this state, the battery fluid can be replenished to the vehicle battery 20 by injecting the battery fluid from the upper part of the outer cylinder 2.

図３は、図２の要部断面図であり、バッテリー液補充器１が車両用バッテリーに装着された状態を示している。フロート８は、バッテリー液の液面Ｌに到達するまで自重で落下するため、車両用バッテリーの液量が不足する場合には、棒状体６の目盛部６ａが内筒４の内部に埋没する。この状態からバッテリー液を補充すると、液面Ｌの上昇によりフロート８および棒状体６が上昇し、図３に示すように、目盛部６ａが内筒４の上方に露出する。こうして、バッテリー液の液量を検出しながら液補充作業を行うことができる。なお、棒状体６の外周面には、内筒４の下端に設けられた係止部４ａと係合可能な抜け止め用の係合部６ｂが設けられている。   FIG. 3 is a cross-sectional view of the main part of FIG. 2, showing a state in which the battery liquid replenisher 1 is mounted on the vehicle battery. Since the float 8 falls under its own weight until reaching the liquid level L of the battery liquid, the scale portion 6a of the rod-shaped body 6 is buried inside the inner cylinder 4 when the amount of liquid in the vehicle battery is insufficient. When the battery liquid is replenished from this state, the float 8 and the rod-shaped body 6 rise due to the rise of the liquid level L, and the scale portion 6a is exposed above the inner cylinder 4 as shown in FIG. Thus, the liquid replenishment operation can be performed while detecting the amount of the battery liquid. The rod-like body 6 is provided with an engagement portion 6b for retaining which can be engaged with the engagement portion 4a provided at the lower end of the inner cylinder 4 on the outer peripheral surface.

図３に示すように、嵌合部２ｂは、筒本体２ａの下端から突出して外部に露出する部分の外周面全体が車両用バッテリーの液口２４の内周面に密着するように、すなわち、嵌合部２ｂの下端が上蓋２２の下面から下方に突出しないように、筒本体２ａからの突出長さが設定されている。この構成によれば、注入したバッテリー液の液はねや液面Ｌの揺れなどが生じた場合でも、嵌合部２ｂの外周面にバッテリー液が付着しないので、バッテリー液補充器１を取り外した後に、バッテリー液が手や衣服などに付着するのを防止することができる。したがって、バッテリー液補充器１の作業性や取扱性を向上させることができる。   As shown in FIG. 3, the fitting portion 2 b is arranged so that the entire outer peripheral surface of the portion protruding from the lower end of the tube main body 2 a and exposed to the outside is in close contact with the inner peripheral surface of the liquid port 24 of the vehicle battery. The protruding length from the cylinder body 2a is set so that the lower end of the fitting portion 2b does not protrude downward from the lower surface of the upper lid 22. According to this configuration, even if the injected battery liquid splashes or the liquid level L fluctuates, the battery liquid does not adhere to the outer peripheral surface of the fitting portion 2b, so the battery liquid replenisher 1 is removed. Later, the battery liquid can be prevented from adhering to hands or clothes. Therefore, the workability and handleability of the battery liquid replenisher 1 can be improved.

嵌合部２ｂの上述した突出長さは、短すぎるとバッテリー液補充器１を上蓋２２の上面に確実に起立させることが困難になり、液補充の作業性を損なうおそれがあるから、これらを考慮して、嵌合部２ｂの突出長さを設定することが好ましい。一例として、筒本体２ａの高さが６０ｍｍ、外径が２８ｍｍである場合に、外径が２０ｍｍの嵌合部２ｂの突出長さを、２ｍｍ程度に設定することができる。   If the above-described protruding length of the fitting portion 2b is too short, it is difficult to reliably stand the battery liquid replenisher 1 on the upper surface of the upper lid 22, and there is a possibility that the workability of liquid replenishment may be impaired. Considering this, it is preferable to set the protruding length of the fitting portion 2b. As an example, when the cylinder body 2a has a height of 60 mm and an outer diameter of 28 mm, the protruding length of the fitting portion 2b having an outer diameter of 20 mm can be set to about 2 mm.

フロート８は、液補充作業の終了後に全体を外筒２の内部に収容可能となるように、嵌合部２ｂを通過できる大きさであることが好ましく、例えば、フロート８が球体である場合には、フロート８の直径を嵌合部２ｂの内径よりも小さくすることが好ましい。また、内筒４は、外筒２の下部にフロート８の収容空間を確保できるように、外筒２内の設置高さを調整することが好ましい。   The float 8 is preferably sized so as to be able to pass through the fitting portion 2b so that the whole can be accommodated in the outer cylinder 2 after the liquid replenishment operation is completed. For example, when the float 8 is a sphere. It is preferable to make the diameter of the float 8 smaller than the inner diameter of the fitting portion 2b. Moreover, it is preferable that the installation height in the outer cylinder 2 is adjusted so that the inner cylinder 4 can ensure the accommodation space of the float 8 in the lower part of the outer cylinder 2. FIG.

この構成によれば、バッテリー液補充器１を車両用バッテリーから取り外す前に、図４に示すように、フロート８が内筒４の下端に当接するまで棒状体６を引き上げて、フロート８の全体を外筒２の内部に収容することで、バッテリー液が付着したフロート８の外周面が外部に露出するのを防止することができる。したがって、この点からもバッテリー液補充器１の作業性や取扱性を向上させることができる。   According to this configuration, before removing the battery fluid replenisher 1 from the vehicle battery, the rod 6 is pulled up until the float 8 contacts the lower end of the inner cylinder 4 as shown in FIG. Can be prevented from being exposed to the outside of the float 8 to which the battery liquid adheres. Therefore, also from this point, workability and handleability of the battery liquid replenisher 1 can be improved.

また、バッテリー液補充器１は、図５に示すように、フロート８を外筒２に収容した後に、外筒２の下端開口を覆うキャップ１０を備える構成であってもよい。キャップ１０は、例えば、樹脂やゴム等の弾性材料からなり、嵌合部２ｂに着脱可能に外嵌される。この構成によれば、使用後のフロート８を外筒２内に確実に保持すると共に、フロート８に付着したバッテリー液の垂れ落ちを防止できるので、バッテリー液補充器１の作業性や取扱性をより向上させることができる。キャップ１０は、嵌合部２ｂに対して螺合等により外嵌される構成であってもよい。   Further, as shown in FIG. 5, the battery liquid replenisher 1 may be configured to include a cap 10 that covers the lower end opening of the outer cylinder 2 after the float 8 is accommodated in the outer cylinder 2. The cap 10 is made of, for example, an elastic material such as resin or rubber, and is detachably fitted to the fitting portion 2b. According to this configuration, the float 8 after use can be securely held in the outer cylinder 2, and the battery liquid adhering to the float 8 can be prevented from dripping, so that the workability and handling of the battery liquid replenisher 1 can be improved. It can be improved further. The cap 10 may be configured to be externally fitted to the fitting portion 2b by screwing or the like.
