【考案の詳細な説明】
この考案は複数個のブルドン管を利用した温度
計に関するものである。[Detailed description of the invention] This invention relates to a thermometer that uses a plurality of Bourdon tubes.
従来は第１図に示すように渦巻の主動ブルドン
管１内端に、主動ブルドン管より少径の微動ブル
ドン管２を接続し、かつ微動ブルドン管２の上部
に指針３を設けている。すなわち主ブルドン管の
バラツキを微動ブルドン管により調整している。
この装置では構造が複数で価格が高価になる欠点
がある。 Conventionally, as shown in FIG. 1, a fine movement Bourdon tube 2 having a smaller diameter than the main movement Bourdon tube is connected to the inner end of a spiral main movement Bourdon tube 1, and a pointer 3 is provided above the fine movement Bourdon tube 2. In other words, variations in the main Bourdon tube are adjusted by the fine Bourdon tube.
This device has the disadvantage that it has multiple structures and is expensive.

チ５を作動せしめている。 Further, as shown in FIG.
is provided, and the micro switch 5 is operated by the disc 4 with a cam.
この装置ではブルドン管の駆動トルクが弱いた
め、マイクロスイツチを確実に作動させることが
困難であつた。 In this device, the driving torque of the Bourdon tube was weak, so it was difficult to operate the microswitch reliably.

ドン管素材内部の残留応力によるエージング現象
（経年変化）やヒステリシス（歪み現象）の発生
原因となる長期間の使用や高頻度の繰返し使用に
十分耐えられなかつた。 In addition, if a Bourdon tube with sufficient wall thickness is used, it will be able to withstand long-term use and frequent repeated use, which can cause aging phenomena (changes over time) and hysteresis (distortion phenomena) due to residual stress inside the Bourdon tube material. I couldn't help it.
この考案はブルドン管の駆動トルクを増大しエ
ージング現象、ヒステリシスの発生が防止できブ
ルドン管の製造が容易であることを目的とする。 The purpose of this invention is to increase the driving torque of the Bourdon tube, prevent aging phenomena and hysteresis, and facilitate the manufacture of the Bourdon tube.
この考案を添付図面の実施例により説明する。 This invention will be explained with reference to embodiments shown in the accompanying drawings.
第３図において、感熱部１１より毛細管１２を
通じて接続金具１３に連通し、接続金具１３に同
一又は回転角度の異る複数個のブルドン管１４，
１５を速通し、両ブルドン管１４，１５は渦巻状
で並列となし、その中心端を主軸１６に連結す
る。 In FIG. 3, the heat sensitive part 11 communicates with the connecting fitting 13 through the capillary tube 12, and the connecting fitting 13 has a plurality of Bourdon tubes 14 with the same or different rotation angles,
Both Bourdon tubes 14 and 15 are spirally arranged in parallel, and their central ends are connected to the main shaft 16.
主軸１６の上部に指針１７又はカム１８を連結
し、かつマイクロスイツチ１９のレバー２０をカ
ム１８に係合せしめる。 A pointer 17 or a cam 18 is connected to the upper part of the main shaft 16, and a lever 20 of a micro switch 19 is engaged with the cam 18.
なお感熱部１１を圧力管に変更することもでき
る。 Note that the heat sensitive section 11 can also be replaced with a pressure tube.
複数のブルドン管の共用により指針又はスイツ
チ機構を作動せしめるのであるが、例えば同一ブ
ルドン管の使用により、確実な駆動トルクが得ら
れると共にエージング現象、ヒステリシスの発生
等が防止できる。 The pointer or switch mechanism is operated by using a plurality of Bourdon tubes in common. For example, by using the same Bourdon tube, reliable driving torque can be obtained and aging phenomena and hysteresis can be prevented.
又異つたブルドン管を用いた場合は両者の合成
された希望の値を得ることもできる。 Furthermore, if different Bourdon tubes are used, a desired value that is a combination of both can be obtained.
さらにトルクの増大をはかり、構造が簡単でブ
ルドン管の製造が容易である等の効果がある。 Furthermore, it has the advantage of increasing torque, having a simple structure, and making Bourdon tubes easy to manufacture.
