Description
【０００１】[0001]
本考案は、エンジンの潤滑油検油装置に関する。 The present invention relates to a lubricating oil inspection device for an engine.
【０００２】[0002]
エンジンの潤滑油検油装置の従来技術として、図９に示すものがある。これは オイルパン内の潤滑油を検油するオイルレベルゲージ１００の抜き差しを案内す るゲージガイドパイプ１０１を備え、このゲージガイドパイプ１０１の下端部１ ０２を環状の弾性シール材１０３のパイプ挿入孔１０４に内嵌し、この弾性シー ル材１０３をエンジン本体１０５の壁１０６にあけたシール材挿入孔１０７に挿 脱自在に取り付けて構成してある。 FIG. 9 shows a conventional technique of a lubricating oil inspection device for an engine. This is equipped with a gauge guide pipe 101 that guides the insertion and removal of an oil level gauge 100 that detects the lubricating oil in the oil pan, and the lower end portion 102 of this gauge guide pipe 101 is a pipe insertion hole of an annular elastic sealant 103. The elastic seal member 103 is internally fitted in 104 and is removably attached to a seal member insertion hole 107 formed in a wall 106 of an engine body 105.
【０００３】 ところで、この従来技術では、弾性シール材１０３をゲージガイドパイプ１０ １の下端部１０２に焼き付けにより離脱不能に取り付けてある。By the way, in this prior art, the elastic seal material 103 is attached to the lower end portion 102 of the gauge guide pipe 101 by baking so as not to be detachable.
【０００４】[0004]
上記従来技術では、次の問題がある。 弾性シール材１０３をゲージガイドパイプ１０１の下端部１０２に焼き付け により取り付けてあるため、弾性シール材１０３の取付時にこれが熱劣化し、弾 性シール材１０３の耐久性が低下する。 The above conventional technique has the following problems. Since the elastic seal material 103 is attached to the lower end portion 102 of the gauge guide pipe 101 by baking, the elastic seal material 103 is thermally deteriorated when attached, and the durability of the elastic seal material 103 is reduced.
【０００５】 弾性シール材１０３をゲージガイドパイプ１０１の下端部１０２に離脱不能 に取り付けてあるため、経時的に劣化した弾性シール材１０３を交換する場合に は、これをゲージガイドパイプ１０１ごと交換する必要があり、不経済であった 。Since the elastic seal material 103 is irremovably attached to the lower end portion 102 of the gauge guide pipe 101, when replacing the elastic seal material 103 that has deteriorated over time, replace it with the gauge guide pipe 101. It was necessary and uneconomical.
【０００６】 本考案は、弾性シール材をゲージガイドパイプの下端部に着脱可能に取り付け ることができる、エンジンの潤滑油検油装置を提供することをその課題とする。An object of the present invention is to provide an engine lubricating oil oil detecting device in which an elastic sealing material can be detachably attached to a lower end portion of a gauge guide pipe.
【０００７】[0007]
本考案は、図１に例示するように、オイルパン１内の潤滑油２を検油するオイ ルレベルゲージ３の抜き差しを案内するゲージガイドパイプ４を備え、このゲー ジガイドパイプ４の下端部５を環状の弾性シール材６のパイプ挿入孔７に内嵌し 、この弾性シール材６をエンジン本体８の壁９にあけたシール材挿入孔１０に挿 脱自在に取り付けた、エンジンの潤滑油検油装置において、次のようにしたこと を特徴とする。 As shown in FIG. 1, the present invention includes a gauge guide pipe 4 for guiding insertion and removal of an oil level gauge 3 for detecting a lubricating oil 2 in an oil pan 1, and a lower end portion of the gauge guide pipe 4. 5 is fitted in a pipe insertion hole 7 of an annular elastic seal material 6, and the elastic seal material 6 is removably attached to a seal material insertion hole 10 formed in a wall 9 of an engine body 8. The oil tester is characterized by the following.
【０００８】 図１〜図８に示すように、上記ゲージガイドパイプ４の下端部５を上記弾性シ ール材６のパイプ挿入孔７に圧入して、上記ゲージガイドパイプ４の下端部５の 外周面と弾性シール材６のパイプ挿通孔７の内周面との密着部分の摩擦抵抗で、 上記弾性シール材６を上記ゲージガイドパイプ４の下端部５に着脱可能に摩擦固 定した。As shown in FIGS. 1 to 8, the lower end portion 5 of the gauge guide pipe 4 is press-fitted into the pipe insertion hole 7 of the elastic seal member 6 so that the lower end portion 5 of the gauge guide pipe 4 is inserted. The elastic seal material 6 was removably fixed to the lower end portion 5 of the gauge guide pipe 4 by the friction resistance of the contact portion between the outer peripheral surface and the inner peripheral surface of the pipe insertion hole 7 of the elastic seal material 6.
【０００９】[0009]
図１に示すように、ゲージガイドパイプ４をエンジン本体８に取り付ける場合 には、ゲージガイドパイプ４の下端部５を弾性シール材６のパイプ挿入孔７に圧 入して、弾性シール材６をゲージガイドパイプ４の下端部５に摩擦固定し、次に この弾性シール材６をシール材挿入孔１０に挿入して固定する。 As shown in FIG. 1, when the gauge guide pipe 4 is attached to the engine body 8, the lower end portion 5 of the gauge guide pipe 4 is press-fitted into the pipe insertion hole 7 of the elastic seal material 6 to attach the elastic seal material 6. The gauge guide pipe 4 is frictionally fixed to the lower end portion 5, and then the elastic sealing material 6 is inserted into the sealing material insertion hole 10 and fixed.
【００１０】 そして、弾性シール材６が経時的に劣化した場合には、ゲージガイドパイプ４ を弾性シール材６ととともにシール材挿入孔１０から抜き取り、ゲージガイドパ イプ４の下端部５から弾性シール材６を取り外し、これを新規なものと交換して 、再度、エンジン本体８に取り付ける。When the elastic seal material 6 deteriorates with time, the gauge guide pipe 4 together with the elastic seal material 6 is pulled out from the seal material insertion hole 10, and the elastic seal is applied from the lower end portion 5 of the gauge guide pipe 4. Remove the material 6, replace it with a new one, and attach it again to the engine body 8.
【００１１】[0011]
弾性シール材をゲージガイドパイプの下端部に摩擦固定により取り付けるた め、焼き付けの場合と異なり、弾性シール材の取付時にその劣化がなく、弾性シ ール材の耐久性が高まる。 Since the elastic seal material is attached to the lower end of the gauge guide pipe by friction fixing, unlike the case of baking, the elastic seal material does not deteriorate when it is attached, and the durability of the elastic seal material increases.
【００１２】 弾性シール材をゲージガイドパイプの下端部に着脱可能に摩擦固定してある ため、弾性シール材が経時的に劣化した場合は、この弾性シール材のみを新規な ものに交換して、ゲージガイドパイプを継続使用でき、経済的である。Since the elastic seal material is removably fixed to the lower end of the gauge guide pipe by friction, if the elastic seal material deteriorates with time, replace only this elastic seal material with a new one. It is economical because the gauge guide pipe can be used continuously.
