Abstract

<P>PROBLEM TO BE SOLVED: To provide an air gun type tool for pressure inspection having a structure connectable directly to a compressor hose, and not destructing a radiator even when a pressure regulator is not used. <P>SOLUTION: A pair is formed by mounting on the tip of the air gun, a pressure gage 4, a check valve 13 on the inlet side of the pressure gage, and a rubber tube 5 on the outlet side for sending the air into the radiator, and screwed and fitted so that the check valve can be inserted inside the tip of the air gun. A through-hole 14 is provided in a passage between the check valve 13 and an opening/closing lever 12 of the air gun. When the rubber tube 15 of the air gun is inserted into the radiator, and the compressor hose is connected to a plug 10, and the opening/closing lever 12 is gripped, pressurized air to be sent into the radiator is slipped wholly out of the through-hole 14 in front of the check valve 13 of the pressure gage 4, and thereby a pressure is not generated in the radiator. The through-hole 14 is closed by a finger, and the radiator can be pressurized mildly, while confirming the pressure by the pressure gage 4, to thereby dispense with the pressure regulator. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

この発明はラジエーターの水漏れ検査に用いて、コンプレッサーホースに直接接続して使用でき、圧力調整器が不要な構造で、安全に任意の検査圧力を得られるエアーガンである。The present invention is an air gun that can be used by directly connecting to a compressor hose for use in a water leak inspection of a radiator, and can safely obtain an arbitrary inspection pressure with a structure that does not require a pressure regulator.

従来コンプレッサーを使用して、ラジエーターの水漏れ検査の加圧検査設備は図１に示すように、コンプレッサーの圧力を直接加えてしまって、ラジエーターを破壊する危険性があるので、減圧する圧力調整器（２）が必要であった。As shown in Fig. 1, the pressure inspection equipment for water leakage inspection of a radiator using a conventional compressor has a risk of destroying the radiator by directly applying the pressure of the compressor. (2) was required.

しかしながら、圧力調整器で減圧する、ラジエーター加圧検査設備は固定式がほとんどで、一般自動車整備工場では普及しておらず、一般エアー工具と同様に、コンプレッサーホースに直接接続できて、圧力調整器がなくてもラヂエーターを破壊しない構造の、エアーガン型の道具を提供することを課題とする。However, most of the radiator pressurization inspection equipment that depressurizes with a pressure regulator is not fixed in general automobile maintenance shops, and like a general air tool, it can be directly connected to a compressor hose, and the pressure regulator It is an object to provide an air gun type tool that does not destroy the radiator even if it is not.

以上の課題を解決するために、第一発明は、図３の断面図に示すように、エアーガンの先端に、圧力計（４）の入り口に逆支弁（１３）、出口にゴム管（１５）を１対としたものを組み込み、エアーガンの開閉バルブ（１２）と圧力計の逆支弁（１３）の間に抜け穴（１４）を設ける。コンプレッサーからの流入空気をプラグ（１０）の流入調整弁（１１）で微弱まで絞り、エアーガンの開閉バルブを握った時に先端に流れる空気を全て抜け穴（１４）から抜けさせる。その微弱な空気の流れを指先（９）で塞ぎ、圧力計を確認しながら緩やかにゴム管に送り、ラジエーターに任意の圧力を得る。ラジエーターに送り込んだ空気は開閉バルブと指先を離しても圧力計の入口の逆支弁の作用により保たれる。プラグと流入量調整ネジの斜視図は図６に示す。
また、第二発明は図４の斜視図に示すように、コンプレッサーの使用できない場合の為に、圧力計（４）逆支弁（１３）ゴム管（１５）を一対とし、先端部分から外せる構造とする。逆支弁（１３）を自転車の虫ゴムを使用するとこにより、自転車の空気入れでも加圧できるようにした。In order to solve the above problems, as shown in the cross-sectional view of FIG. 3, the first invention has a back valve (13) at the inlet of the pressure gauge (4) and a rubber tube (15) at the outlet as shown in the cross section of FIG. Is installed, and a through hole (14) is provided between the open / close valve (12) of the air gun and the reverse support valve (13) of the pressure gauge. The inflow air from the compressor is throttled to a weak level by the inflow adjustment valve (11) of the plug (10), and all the air flowing to the tip when the air gun open / close valve is gripped is released from the through hole (14). The weak air flow is closed with the fingertip (9), and it is gently sent to the rubber tube while checking the pressure gauge to obtain an arbitrary pressure on the radiator. The air sent to the radiator is maintained by the action of the reverse valve at the inlet of the pressure gauge even if the on-off valve and fingertip are separated. A perspective view of the plug and the inflow adjusting screw is shown in FIG.
Further, as shown in the perspective view of FIG. 4, the second invention has a structure in which a pressure gauge (4) a reverse support valve (13) and a rubber pipe (15) are paired and removed from the tip portion when the compressor cannot be used. To do. The reverse support valve (13) is made of bicycle rubber so that it can be pressurized even when the bicycle is inflated.

第一発明、または第二発明によれば、自動車整備工場において、エアー工具と同様な扱いで、ラジエーターの水漏れ検査が出来るようになり、コンプレッサーのない場合も一般に普及している安価な自転車の空気入れを使用し、加圧検査が出来るようになった。  According to the first invention or the second invention, in an automobile maintenance shop, it becomes possible to perform a water leak inspection of a radiator in the same manner as an air tool. A pressurization test can now be performed using an air pump.

この発明の一実施形態を、図５に示す。
本体（８）はエアーガンで、プラグ（１０）に空気の流れを制限する流量調整ネジがある（図６参照）、先端に圧力計（１４）と逆支弁（図４の１３参照）とゴム管（１５）を１対したものを有する（図４参照）、エアーガンの開閉レバー（１２）と圧力計の入口の逆支弁（図４の１３参照）の間に抜き穴（１４）を設けている構造とする。One embodiment of the present invention is shown in FIG.
The main body (8) is an air gun, and the plug (10) has a flow rate adjusting screw for restricting the air flow (see FIG. 6), a pressure gauge (14), a reverse valve (see 13 in FIG. 4) and a rubber tube at the tip. (15) has a pair (see FIG. 4), and a through hole (14) is provided between the open / close lever (12) of the air gun and the reverse support valve (see 13 in FIG. 4) at the inlet of the pressure gauge. Structure.

「実施形態の効果」
この実施形態によれば、本発明エアーガンのゴム管をラヂエーターに差し込み、プラグにコンプレッサーホースを接続し、開閉レバーを握るだけではラヂエーターには圧力がまったく掛からず、微弱に抜き穴から流れ出る空気を指で塞ぐことで、緩やかな圧力の上昇を圧力計で確認しながらラヂエーターに任意の検査圧力が得られるので、圧力調整器の必要がなく、構造が簡単である。"Effect of the embodiment"
According to this embodiment, the rubber tube of the air gun of the present invention is inserted into the radiator, the compressor hose is connected to the plug, and the pressure is not applied to the radiator at all by simply grasping the opening / closing lever, and the air that flows out of the punch hole is weakly indicated. By plugging in with the pressure gauge, an arbitrary inspection pressure can be obtained in the radiator while confirming a gradual rise in pressure with a pressure gauge, so there is no need for a pressure regulator and the structure is simple.

「他の実施形態」
実施形態では、抜け穴（１４）の位置は逆支弁（１３）と開閉レバー（１２）の間に空ければ位置は問わない。"Other embodiments"
In the embodiment, the position of the through hole (14) is not limited as long as it is vacant between the reverse support valve (13) and the opening / closing lever (12).

本発明は、ラジエーターの圧力検査のみならず、本発明エアーガン出口のゴム管でラジエーター注水口横のオーバーフローパイプにより、ラジエーター内部に圧力を送り込んだ後、それを外し、ラジエーター内部圧力の変化をキャップ開放時の内部圧力の噴出し音、ラジエーターホースの膨らみで確認することで、キャップ及び注水口の保持力の良否判断が可能で、産業上の利用の可能性を有する。In the present invention, not only the pressure check of the radiator, but also the rubber pipe at the outlet of the present invention, the overflow pipe next to the water inlet of the radiator is used to send the pressure into the radiator, then the pressure is removed, and the change in the internal pressure of the radiator is opened. It is possible to judge whether the holding power of the cap and the water inlet is good or not by checking the sound of the internal pressure at the time and the swelling of the radiator hose.
