Abstract

一种不带镜片挡圈组件的观液镜,它是通过本体上的外螺纹与镜片座上的内螺纹联接,利用本体顶部的圆环形平面将O型橡胶密封圈和放大镜压紧。O型橡胶密封圈既密封螺纹,又密封和固定放大镜。

Description

观液镜
本实用新型是观察空调系统中氟里昂液体流动情况的装置。
目前，公知的观液镜是由本体、O型橡胶密封圈、放大镜、镜片座、镜片挡圈(组件)和护盖装配而成。本体有进液孔和出液孔，将其联接在空调系统中，即可透过放大镜观察氟里昂液体的流动情况。但是，这种观液镜是由本体上的内螺纹与镜片座上的外螺纹联接，其O型橡胶密封圈仅用于螺纹联接的密封，而放大镜在镜片座中必须用镜片挡圈组件来固定和密封，其结构相当复杂。
本实用新型的目的是提供一种没有镜片挡圈组件的观液镜。
本实用新型的目的是这样实现的：在本体上，O型橡胶密封圈、放大镜、镜片座和护盖顺序装配，其特征是：本体上的外螺纹与镜片座的内螺纹联接，利用本体顶部的圆环形平面将O型橡胶密封圈和放大镜压紧，O型橡胶密封圈同时起到内、外螺纹联接处的密封及放大镜的固定和密封作用。
由于采用上述方案，不再需要镜片挡圈组件，结构简单。
下面结合附图和实施例对本实用新型进一步说明。
图中：1.本体     2.O型橡胶密封圈
      3.放大镜   4.镜片座   5.护盖在图中，本体(1)的下部是进液孔和出液孔，利用螺纹分别与进液管和出液管相连。本体(1)的顶部是圆环形平面，与O型橡胶密封圈(2)、放大镜(3)、镜片座(4)、护盖(5)顺序联接。由于本体(1)上的外螺纹与镜片座(4)上的内螺纹联接，将其间的O型橡胶密封圈(2)、放大镜(3)压紧。O型橡胶密封圈(2)不但将本体(1)和镜片座(4)的螺纹联接处密封，而且将放大镜(3)固定和密封，护盖(5)装在镜片座(4)的外面，其中间有孔，通过此孔和放大镜(3)即可清晰地看到本体(1)内氟里昂液体的流动情况。

Claims (2)

1.一种观液镜，在本体上，O型橡胶密封圈、放大镜、镜片座和护盖顺序装配，其特征是：本体上的外螺纹与镜片座上的内螺纹联接，利用本体顶部的圆环形平面将O型橡胶密封圈和放大镜压紧。
2.根据权利要求1所述的观液镜，其特征是：O型橡胶密封圈既密封螺纹，又密封和固定放大镜。
