Abstract

The utility model relates to a clock type double metal thermometer. Various thermometric instruments increasingly become the needs for all industries and families. The utility model is formed by the integration of the double metal thermometer and various clocks, such as machine clocks, semiconductor clocks and quartz crystal clocks. The utility model simultaneously observes the air temperature and the time, has two functions and the temperature measurement accuracy is suitable for common requirements. The utility model has the advantages of high trivoltine degree, firmness, low cost, convenient use, convenient maintenance, etc.

Description

Clock type double metal thermometer

Along with development and national economy, corresponding the increasing of various temperature instrumentation kinds become the necessity of all trades and professions and part family.In real work and life, when needs are known the air themperature of some time branch, should be from observation time on the clock and watch, observation station's temperature indicative on instrument exists some troubles and inconvenience again; The shortcoming that used in addition glass temperature table has the reading difficulty and damages easily.

The utility model can be indicated temperature and time at that time simultaneously, also can only use as thermometer or clock, can overcome above-mentioned inconvenience and shortcoming.

Accompanying drawing 1 is an embodiment synoptic diagram of the present utility model.The clock type bimetallic thermometer, mainly by the bimetallic thermometer mechanism (C) in its casing assembly (A), temperature-time scale (B) and the shell, (D) combine constitutes clockwork (containing various such as machinery, semiconductor, quartz crystal clock mechanism).On temperature-time scale (B) face, temperature scale, number, time-division time scale are arranged.Temperature pointer (4) is driven by its bimetallic thermometer mechanism (C), clockwork (D) respectively with hour hands (3), minute hand (2), second hand (1), the corresponding temperature and time of indication on the temperature-time scale.Each rotating shaft of temperature pointer, hour hands and minute hand is positioned on the same axis of scale central authorities.As accompanying drawing 1(a), (b), a second hand or a second lamp (1) are positioned on the side of scale central authorities.Second, lamp triggered luminous by time pulse electric current second that the dynamo-electric mechanism of clock (D) sends.

Accompanying drawing 2 is bimetallic thermometer of the present utility model (C) mechanism for implementing illustration intentions.Scale of one column cap bearing (6) keyed is adjusted button frame (7), be fixed on clockwork (D) frame plate the time minute hand shaft axis position on.Axostylus axostyle (5) is supported by time bearing (the containing the column cap bearing) hole on the minute hand shaft axis on two frame plates of clockwork.The temperature-sensing element of bimetallic thermometer is made of double metal spiral sheet (9) and core hoop (8) thereof.The core banding hoop of temperature-sensing element is on axostylus axostyle (5), and scale is adjusted the notch on the button frame (7), and the double metal spiral sheet outer end of temperature-sensing element is being held in the mouth.Temperature pointer (4), hoop fixes on the outer end head of axostylus axostyle (5).During temperature variation, temperature pointer indicates corresponding temperature value on temperature-time scale (B).When its temperature error of indication is overproof, can adjusts button frame (7) by scale and adjust.

The thermometric degree of accuracy of bimetallic thermometer can reach ± 1 ℃.The temperature-measuring range of thermometer, pointer full scale subtended angle, indication heat sensitivity, generally can select respectively :-35 ℃～+ 45 ℃, 120 °～270 ° ,≤4 °/℃.

In brief, respectively will be such as machinery, semiconductor, quartz crystal clock design, through a little corresponding modify, mechanism is combined with bimetallic thermometer, promptly constitutes the clock type bimetallic thermometer of all size.Because its wide in variety, parts three change degree height are so the utility model also has inexpensive advantage.

The utility model can be widely used in all trades and professions and each family.

Claims

1, the utility model, be the clock type thermometer, it is characterized in that: a bi-metal temperature table is furnished with such as machinery, semiconductor, the dynamo-electric mechanism (D) of quartz crystal clock, its temperature pointer, hour hands, each rotating shaft of minute hand, be positioned at same temperature-time scale (B) central authorities, and on same axis.

2, the described clock type bimetallic thermometer of claim 1 is characterized in that: bimetallic thermometer mechanism, mainly adjust button frame, axostylus axostyle, bearing bracket stand and temperature pointer by thermometal temperature-sensing element, scale and constitute.

3, claim 1,2 described clock type bimetallic thermometers is characterized in that: on its temperature-time scale (B), temperature scale, number and time-division time scale are arranged.
