【考案の詳細な説明】
本考案は圧力式温度記録計における外気温度補
償機構に関するものである。[Detailed Description of the Invention] The present invention relates to an outside air temperature compensation mechanism in a pressure type temperature recorder.
従来における圧力式温度記録計の外気温度補償
は作動板、記録ペン等の機構部の変位により二次
的な補正を行なつていたものであり、精度の面で
問題があつた。 Conventional pressure-type temperature recorders compensate for outside air temperature by performing secondary corrections based on the displacement of mechanical parts such as actuating plates and recording pens, which poses a problem in terms of accuracy.
これに対し、本考案では圧力バランス部に外気
温に応じて変位する温度変位体を直接組入れて精

て、該スプリングの端部をバイメタル等の温度変
位体で受ける構造を組み入れ、その変位量をスプ
リングの力に変換して補正するものである。 In contrast, the present invention aims to improve accuracy by directly incorporating a temperature displacement body that displaces according to the outside temperature into the pressure balance section. That is, in the present invention, in contrast to the conventional basic structure consisting of a force due to the internal pressure of the bellows and a spring that opposes this force, a structure is incorporated in which the end of the spring is supported by a temperature displacement body such as a bimetal, and the displacement thereof is This corrects the amount by converting it into spring force.
以下本考案の実施例について図面と共に説明す

接する。ベローズ３には感温筒を有するキヤピラ
リチユーブ５が接続される。 An embodiment of the present invention will be described below with reference to the drawings. A bellows 3 is provided on one side of a case 1 with a seat plate 2 interposed therebetween, and a driving body 4 abuts on a moving end 3a of the bellows 3. A capillary tube 5 having a temperature-sensitive cylinder is connected to the bellows 3.
駆動体４は筒状に形成され、ベローズ３との当
接部の反対側は圧力設定用の圧縮スプリング６の
受部として構成される。 The drive body 4 is formed into a cylindrical shape, and the side opposite to the contact portion with the bellows 3 is configured as a receiving portion for a compression spring 6 for setting pressure.
圧縮スプリング６の他端は圧縮調整板７により
受け止められ、該圧力調整板７には圧力調整ネジ
８が螺合している。 The other end of the compression spring 6 is received by a compression adjustment plate 7, and a pressure adjustment screw 8 is screwed into the pressure adjustment plate 7.
９はペンレバーであり、前記駆動体４の内部に
対する衝合突部９ａとケース１の支点１ａに対す
る係合部９ｂを有し、引張りスプリング１０が内
端部に係止されることにより衝合突部９ａは常時
駆動体４に対して圧接する。 Reference numeral 9 denotes a pen lever, which has a protrusion 9a that abuts against the inside of the drive body 4 and an engaging part 9b that engages with the fulcrum 1a of the case 1, and when the tension spring 10 is locked to the inner end, the abutment comes into contact. The portion 9a is always in pressure contact with the driving body 4.
以上説明したところは従来公知の構造である
が、本考案においては、圧力設定用の圧縮スプリ

合して設けられる。 The above-described structure is conventionally known, but in the present invention, a cap-shaped bimetal 11, 11 is placed between the driving body 4 and the adjusting plate 7 at both ends of the compression spring 6 for pressure setting. The hole 11a is provided by engaging the protrusion 4a of the driver 4 or the adjustment screw 8.

めてベローズ３の伸張成分に対抗させる。 In the above configuration, when the outside air temperature around the bellows 3 rises, the internal pressure of the bellows 3 increases and the moving end 3a of the bellows tries to extend outward.
11 warps outward, increasing the elasticity of the compression spring 6 to counteract the expansion component of the bellows 3.

どの優れた効果を奏するものである。 As described above, the present invention provides a compression spring opposite to the thermally responsive body via a drive body, a pen lever is driven by the drive body, and a temperature displacement body using a bimetal at the end of the compression spring. In addition, since the compression spring is supported by a compression adjustment plate to which an adjustment screw is screwed, it is possible to further improve the compensation accuracy of the outside air temperature in the pressure-type temperature recorder, and also to reduce the The adjustment of the position of the pen lever, that is, the adjustment of the pen lever, can be carried out very easily using this adjustment screw, which provides an excellent effect.
