Description

本考案は、指針式圧力計及びそれにより組成された充気測定器に関し、特に、測定圧力値を校正できる指針式圧力計及びそれにより組成された充気測定器に関するものである。 The present invention relates to a pointer-type pressure gauge and a charge measuring device composed thereof, and more particularly to a pointer-type pressure gauge capable of calibrating a measured pressure value and a charge measuring device composed thereof.

日常生活において、圧力計は、通常はインフレ物の気圧を測るのに使われる。たとえば、タイヤ内部のタイヤ圧力及びバスケットボールの内部圧力等を測るのに使われる。現有の圧力計は、指針式圧力計とデジタル式圧力計を主流としている。その中、デジタル式圧力計は、高い敏感度と高い精確度等の美点を備えているが、その構造が精密な電子装置であるため、一般的に、価格が高くて、震動に耐えないで、保養しにくくて、及び電源を使用しなければならない等の欠点がある。 In everyday life, pressure gauges are usually used to measure the pressure of inflation. For example, it is used to measure the tire pressure inside the tire and the internal pressure of basketball. The existing pressure gauges are mainly pointer-type pressure gauges and digital pressure gauges. Among them, the digital pressure gauge has beauty such as high sensitivity and high accuracy, but its structure is a precise electronic device, so it is generally expensive and cannot withstand vibration. However, there are drawbacks such as difficulty in recuperating and having to use a power source.

比べれば、指針式圧力計は、その構造が簡単で、震動に耐えて、電源をつけなくても使用できること等の美点を備えって、今まで相変わらず社会大衆から歓迎を受けてある。大体の指針式圧力計は、ほとんどスプリングの弾力と気体圧力の間の平衡原理を利用して、フック法則（Hooke’s law：弾力＝バネ定数×変位バネののびは、それに加えられた力に比例する）の応用を合わせて、それによって、指針を駆動させて測定圧力値を表示する。 In comparison, the pointer-type pressure gauge has received the welcome from the public as before, with the beauty of being simple in structure, resistant to vibration and being usable without turning on the power supply. Most pointer-type pressure gauges use the principle of balance between spring elasticity and gas pressure, and the Hooke's law (elasticity = spring constant x displacement spring expansion is proportional to the force applied to it. ), Thereby driving the pointer and displaying the measured pressure value.

また、実務運用の上で、所定の測定範囲内に測った測定圧力値は、いっそう精確となれる。例えば、指針式圧力計の最大測定範囲（即ち、目盛板に表示された測定範囲である）は、０〜２００psiであって、一般的に、最初で使用している時、大体中央1/3の測定範囲（即ち65〜135psiの測定範囲である）内で測った測定圧力値は、いっそうに精密で精確となる。しかし、スプリングの弾力が失い始めてくることに従い、だんだんと大体後面1/3の測定範囲（即ち135〜200psiの測定範囲である）内で図った測定圧力値は、いっそうに精密で精確となる。 Moreover, the measured pressure value measured within a predetermined measurement range can be made more accurate in practical operation. For example, the maximum measurement range of a pointer-type pressure gauge (that is, the measurement range indicated on the dial plate) is 0 to 200 psi, and is generally about 1/3 of the center when first used. The measured pressure value measured within the measuring range (ie, the measuring range of 65 to 135 psi) becomes more precise and accurate. However, as the spring's elasticity begins to lose, the measured pressure value within the measuring range of about 1/3 of the rear surface (that is, the measuring range of 135 to 200 psi) becomes more precise and accurate.

指針式圧力計は、長期に使用されていた後、いったんスプリングの弾力が失ってしまって、また、スプリングの弾性係数もついてに変動しており、同時に、おのおの連結部品は、緩くなってまたはがたがたの現象を起こして、それによって、測った測定圧力値を影響してしまう。従って、いったんより小さい圧力を測る時に、測った測定圧力値は、実際の圧力値と大きな誤差を生じている。 The pointer-type pressure gauge, after being used for a long period of time, once lost its spring elasticity and fluctuated with the elastic modulus of the spring, and at the same time, each connecting part became loose or rattled This causes the measured pressure value to be affected. Therefore, once a smaller pressure is measured, the measured pressure value has a large error from the actual pressure value.

およそ所属技術領域の中で、通常知識を持つ専門者にとって、従来の指針式圧力計は、静態なゼロ点調整機能と動態な圧力調整機能を欠いているように知られる。従って、初期化のゼロ点調整を行うことができない。即ち、少数の指針式圧力計は、ゼロ点調整の回転ボタンを設置しても、指針式圧力計のみに対して静態なゼロ点調整を行って、異なる測定範囲による圧力測定標的に対応して適当な動態圧力調整を行うことができない。従って、本考案の考案者は、指針式圧力計に係る結構の改良を必要として、それに動態な圧力調整の機能を備えさせることを深く感じている。 In the technical field of which the profession belongs, it is known to the expert with ordinary knowledge that the conventional pointer-type pressure gauge lacks a static zero-point adjustment function and a dynamic pressure adjustment function. Therefore, the zero point adjustment for initialization cannot be performed. In other words, a small number of pointer-type pressure gauges can perform zero-point adjustment statically only for the pointer-type pressure gauges, even if a zero-point adjustment rotary button is installed, to support pressure measurement targets with different measurement ranges. Appropriate dynamic pressure adjustment cannot be performed. Therefore, the inventor of the present invention deeply feels that it requires a considerable improvement of the pointer-type pressure gauge and has a dynamic pressure adjustment function.

上述によって、従来の指針式圧力計において、一般的に動態な圧力調整機能を欠いているため、指針式圧力計が、長く使い続けられたら、スプリングの弾力性が失われて、そしておのおの連結部品は、緩くなってまたはがたがたの現象を発生して、それによって、測った測定圧力値を影響してしまう。更に、多くの圧力測定標的の落差が大きくなって、しかもそれぞれ異なった測定範囲に当たる時、動態な圧力調整を行って精確な測定圧力値を測ることができない。 As described above, since the conventional pressure gauges generally lack a dynamic pressure adjustment function, if the pointer pressure gauges are used for a long time, the elasticity of the springs is lost, and each connecting part Causes a loose or rattling phenomenon, thereby affecting the measured pressure value. Furthermore, when the drop of many pressure measurement targets becomes large and each falls in a different measurement range, it is impossible to accurately measure the pressure value by performing dynamic pressure adjustment.

従って、本考案の主な目的は、指針式圧力計を提供して、当該指針式圧力計の圧力計本体内に貫通道を開設しており、それに直接に圧力調整部材を貫通道の一端に設置させて、しかも指針部材と圧力調整部材を連動させており、それによって、圧力調整部材で動態圧力の校正を行う。 Therefore, the main object of the present invention is to provide a pointer-type pressure gauge and to establish a through passage in the main body of the pointer-type pressure gauge, and to directly attach a pressure adjusting member to one end of the through-passage. In addition, the pointer member and the pressure adjusting member are interlocked, and the dynamic pressure is calibrated by the pressure adjusting member.

本考案は、従来の技術問題を解決するために、指針式圧力計を提供して、前記指針式圧力計は、圧力計本体と、指針部材と、圧力調整部材を含む。前記圧力計本体は、貫通道を備えており、前記指針部材は、前記圧力計本体に組み合わされて、それに前記貫通道と相通しており、前記圧力調整部材は、前記貫通道に設置されて、しかも、調節チューブと、弾性部品と、調節操作部材を含む。標準圧力値を有する気体が前記貫通道に入り込む時、前記気体は、前記調節チューブを駆動させて前記弾性部品を圧縮して、それによって前記調節チューブが前記指針部材を駆動させて、測定圧力値を表示しており、前記測定圧力値が、当該標準の気圧値と一致しない時に、前記調節操作部材は、前記弾性部品を伸縮するに用いられて、それによって動態的に当該測定圧力値を校正する。前記指針式圧力計は充気部材と結合する時、充気測定器を構成して、それは、充気気体の充気圧力値を表示する。 The present invention provides a pointer-type pressure gauge in order to solve the conventional technical problems, and the pointer-type pressure gauge includes a pressure gauge body, a pointer member, and a pressure adjusting member. The pressure gauge main body includes a through passage, the pointer member is combined with the pressure gauge main body and communicates with the through passage, and the pressure adjusting member is installed in the through passage. In addition, an adjustment tube, an elastic part, and an adjustment operation member are included. When a gas having a standard pressure value enters the through-passage, the gas drives the adjustment tube to compress the elastic part, thereby causing the adjustment tube to drive the pointer member to measure the pressure value. When the measured pressure value does not match the standard atmospheric pressure value, the adjustment operation member is used to expand and contract the elastic part, thereby dynamically calibrating the measured pressure value. To do. When the pointer-type pressure gauge is combined with the charge member, it constitutes a charge measurement device, which displays the charge pressure value of the charge gas.

本考案の好ましい実施例によれば、圧力調整部材は、更にゼロ点調整部材を含み、前記ゼロ点調整部材は、貫通道の一端に設置されて、しかも気体が前記貫通道に入れる前に調整チューブと連動しており、それによって、気体が前記貫通道に入れる前に指針部材が表示した測定圧力値をゼロ点にさせる。 According to a preferred embodiment of the present invention, the pressure adjusting member further includes a zero point adjusting member, and the zero point adjusting member is installed at one end of the through passage and is adjusted before gas enters the through passage. In conjunction with the tube, the measured pressure value displayed by the pointer member before the gas enters the through passage is brought to the zero point.

従来の技術に係る指針式圧力計と比べれば、本考案に係る指針式圧力は、前記指針式圧力計の圧力計本体内に貫通道を開設しており、直接に圧力調整部材を貫通道の一端に設置させてある。従って、標準圧力値を有する気体が前記貫通道に入り込む時、測定圧力値が測られていて、前記測った測定圧力値が、当該標準の気圧値と一致しない時に、前記圧力調整部材と前記指針部材との連動を介して、動態的に前記測定圧力値を校正することができる。 Compared with the pointer-type pressure gauge according to the prior art, the pointer-type pressure according to the present invention has a penetrating path in the pressure gauge body of the pointer-type pressure gauge, and the pressure adjusting member is directly connected to the penetrating pressure gauge. It is installed at one end. Therefore, when a gas having a standard pressure value enters the through-passage, a measured pressure value is measured, and when the measured pressure value does not match the standard atmospheric pressure value, the pressure adjusting member and the pointer The measured pressure value can be calibrated dynamically through interlocking with the member.

上述から明らかに分かって、本考案に係る指針式圧力計は、異なる測定範囲に当たる多種な圧力測定標的に対して圧力測定を行う前に、適当に動態な圧力校正を行うことができ、従って、本考案に係る指針式圧力計は確かに十分に精確な測定圧力値を測ることができる。 As can be clearly seen from the above, the pointer-type pressure gauge according to the present invention can appropriately perform dynamic pressure calibration before performing pressure measurement on various pressure measurement targets in different measurement ranges. The pointer-type pressure gauge according to the present invention can surely measure the measured pressure value sufficiently accurately.
