Abstract

The utility model discloses a light-gathering protective sleeve of a thermometer, which solves the problems that in the practical production, thermometers are fragile and easy to be broken, and indication of the thermometers is not easy to read in dark environments. A main body of the light-gathering protective sleeve of the thermometer is divided into an upper sleeve, a transitional sleeve and a lower sleeve from up to bottom, wherein the internal diameter of the upper sleeve is greater than the external diameter of the thermometer, a vertical bar-shaped gap is arranged on the side wall of the upper sleeve, the width of the gap is greater than the external diameter of the thermometer and the length of the gap equals to that of the upper sleeve, and the thermometer is inserted into the lower sleeve; and the protective sleeve also comprises a reflection sheet whose surface is irregular, wherein the reflection sheet is plastered on the inner wall of the upper sleeve. The metal protective sleeve of the utility model can ensure that the thermometer is not broken or fractured; and the reflection sheet whose surface is irregular is arranged on the inner wall of the protective sleeve, which ensures that indicated value of the thermometer can be read accurately and authentically in the dark environments.

Description

Thermometer optically focused protective sleeve

Technical field

The utility model relates to a kind of thermometer protective device in use.

Background technology

In field produces, temperature value is a very important manufacturing parameter, is mercury or alcohol thermometer and thermometric generally uses.When specifically measuring temperature, thermometer is inserted in the specific thermometer hole, because the main body of thermometer is to be processed by frangible glass, is easy to because of carelessness fractureed so use, after thermometer fractureed, the half thermometer of folding in thermometer hole was not easy taking-up very much; In addition at night or cloudy day or tolerable indoor in daylighting; The indicating value of thermometer is difficult to see clearly; The result is that the error of reading is big naturally, so under dim condition, need accomplish reading by electric torch usually; But the light beam direct irradiation that promptly uses electric torch also is not easy to see clearly temperature value on thermometer.

Summary of the invention

The purpose of the utility model provides a kind of optically focused protective sleeve of thermometer, and this protective sleeve can protect thermometer not fractureed, and can guarantee again under dim condition, accurately, clearly to read temperature value, thereby guarantee the authenticity of reading.

For realizing the foregoing invention purpose, the technical scheme that the application adopts is: a kind of thermometer optically focused protective sleeve, and its main body adopts tube-in-tube structure; Be divided into three sections according to from top to bottom order during vertical the setting; Be respectively upper bush, transition sleeve and lower sleeve, wherein the internal diameter of upper bush is provided with the vertical bar v notch v greater than the external diameter of thermometer on the sidewall of upper bush; The width of breach is greater than the external diameter of thermometer, and the length of breach equals the length of upper bush; Thermometer body or thermometer are inserted in the lower sleeve after being with ring outward, and thermometer can be along the lower sleeve axial float; This protective sleeve also comprises the reflecting piece of a surface irregularity in addition, and the specification after the specification of reflecting piece and upper bush inwall flatten is identical, and said reflective silver is attached on the upper bush inwall.

Vertical bar v notch v on the preferred upper bush sidewall, its width equals the internal diameter of upper bush; What also preferred reflecting piece adopted is zinc-plated molybdenum sheet; Also preferred lower sleeve inwall is lined with rubber layer or built-in cushion rubber.

Beneficial effect: the application's thermometer optically focused protective sleeve, can frangible thermometer be inserted in the firm metal-coating, expose temperature measuring head; And then be inserted in and carry out thermometric in the thermometer hole; Effectively protected thermometer not fractureed, even fracture has taken place thermometer, cleaning is got up also very convenient; In addition; The rough reflectorized material that posts in this protective sleeve; Have certain astigmatism effect, this astigmatic effect can be alleviated the intensity of high light, makes light become softer; Be well suited for the fine comfort level of eye, thereby help operating personnel in dim environment, also can clearly see the scale value of thermometer clearly.

Embodiment

Below in conjunction with accompanying drawing the application is further described:

Combine shown in Figure 2 by Fig. 1: a kind of thermometer optically focused protective sleeve; Its main body adopts tube-in-tube structure, is divided into three sections according to from top to bottom order during vertical the setting, is respectively upper bush 1, transition sleeve 2 and lower sleeve 3; Wherein the internal diameter of upper bush 1 is greater than the external diameter of thermometer 4; Vertical bar v notch v 5 is set on the sidewall of upper bush 1, and the width of breach 5 is greater than the external diameter of thermometer 4, and the width of breach 5 preferably equals the internal diameter of upper bush 1; What the inwall of upper bush 1 revealed like this is maximum, and the length of breach 5 equals the length of upper bush 1; Thermometer 4 bodies or thermometer are inserted in the lower sleeve 3 after being with ring outward, and thermometer 4 can be along lower sleeve 3 axial floats, also can be in lower sleeve 3 wall liner rubber layer or cushion rubber is set, rubber layer or cushion rubber can effectively block the downslide of thermometer; This protective sleeve also comprises the reflecting piece 6 of a surface irregularity in addition, and the specification after the specification of reflecting piece 6 and upper bush 1 inwall flatten is identical, and said reflecting piece 6 is attached on the inwall of upper bush 1; Above-mentioned reflecting piece 6 can adopt the reflectorized material of the lamp bowl use that constitutes searchlight; Like zinc-plated molybdenum sheet material; The rough surface of this kind material has the astigmatism effect, and the light beam that the electric torch irradiation is come spreads out, and helps the operator and clearly sees the temperature indicating value clearly.

Claims (4)
