Abstract
The utility model relates to a new double-pointer type temperature humidity meter, comprising a meter disc with a temperature scale and a humidity scale, a back cover, a temperature pointer driving device and a humidity pointer driving device. The utility model is characterized in that a hairspring-shaped spiral spring is made by thermosensitive and moisture sensitive materials; one end of the hairspring-shaped spiral spring is fixed on each rotary shaft, the other end of the hairspring-shaped spiral spring is penetrated through holes on the side wall of each bracket; a shaft sleeve is arranged outside each rotary shaft and is fixed on each bracket; the bracket is a closed-shaped frame, each bracket is provided with an inwards concave groove on the outer wall nearest the back cover; the back cover of the utility model is provided with two through holes corresponding to the positions of the two grooves. The utility model has the advantages of accurate indication, convenient calibration and simple structure.
Description
The utility model relates to a kind of thermohygrometer, while display environment temperature and relative humidity, and be convenient to calibration, belong to novel general instrument.
Existing two pointer thermohygrometers drive temperature pointer and humidity pointer respectively with displays temperature and humidity by thermal sensing element and humidity-sensitive element.The gear train of two pointers is the same.
The shortcoming that said structure exists is: when the examination and test of products, check and correction and after sale service, the bonnet swinging mounting that must will show to drive whole gear train rotation, makes pointer point to the right value of scale, so troublesome poeration, consuming timely takes a lot of work again.Be not easy to indicated value is aligned accurate orientation.
The purpose of this utility model is to develop a kind of thermohygrometer of new structure, makes it to be convenient to temperature value and humidity value are aligned, and it is accurate to reach indication.
Design proposal of the present utility model is: a kind of novel pointer thermohygrometer, comprise the dial plate, bonnet, temperature pointer gear train and the humidity pointer gear train that have two scales of temperature and humidity, it is characterized in that: temperature pointer is fixed on the rotation axis, rotation axis has a fixed hub outward, this axle sleeve is fixed on the support, the volute spring of a balance-like of making by thermal sensing element, its the inner is connected on this rotation axis, the through hole of rack side wall is passed in its outer end, so that should hold retractable, and do not produce transversal displacement; This support is a closed shape frame, on this support and the immediate outer wall of watch back cover, establishes a groove that caves inward; The gear train of humidity pointer is identical with the gear train of temperature, be that humidity pointer is fixed on the rotation axis, rotation axis has a fixed hub outward, this axle sleeve is fixed on another support, a balance-like volute spring of making by humidity-sensitive element, and its inner is connected on this rotation axis, the through hole of rack side wall is passed in its outer end, so that this end retractable and do not produce transversal displacement, this support is a closed shape frame, establishes a groove that caves inward on this support and the immediate outer wall of watch back cover; Correspond to two grooves on two supports on the bonnet of table, open two through holes, the big I of through hole extend in the groove screwdriver.
Advantage of the present utility model and effect are: 1, the helical spring end of balance-like made of thermal sensing element is fixed on the rotation axis, rotate in fixed hub by rotation axis, drive the beat of pointer, the displacement of temperature value and pointer is a curved line relation, according to calculating and test figure, dial scale and temperature value are corresponding relation, to realize the direct demonstration of ambient temperature value.Equally, the helical spring end of balance-like by humidity-sensitive element is made owing to be fixed on the rotation axis, drive pointer by rotation axis and swings in fixed hub, and its indicated value and humidity value also are corresponding relation.2, when detecting and after sale service need proofread and correct the indicated value of this table the time, needn't open bonnet and remove swinging mounting, but put in the through hole of bonnet with circular knife, be inserted in the groove of support, swinging mounting drives temperature or humidity gear train unitary rotation, thereby the relative dial plate with pointer of rotation axis rotates, and realizes the purpose of calibration, removes the time-consuming program of opening bonnet from.3, the utility model is simple in structure, is convenient to operation.Below in conjunction with accompanying drawing for an embodiment:
Fig. 1 is a kind of novel two pointer thermohygrometer front elevation.Fig. 2 is a kind of novel two pointer thermohygrometer general structure A-A view.Fig. 3 is a kind of novel two pointer thermohygrometer temperature indication drive mechanism figure.Fig. 4 is a kind of novel two pointer thermohygrometer temperature indication drive mechanism sectional view.Fig. 5 is humidity indication drive mechanism figure in a kind of novel two pointer thermohygrometer.Fig. 6 is a humidity indication drive mechanism sectional view in a kind of novel two pointer thermohygrometer.
Embodiment: a kind of novel two pointer Hygrothermograph, as Fig. 1, shown in Figure 2, comprise the dial plate [1] that has two scales of temperature and humidity, back table lid [2], temperature pointer gear train [3], humidity pointer gear train [4], it is characterized in that: temperature pointer [5] is fixed on the rotation axis [6], rotation axis has a fixed hub [7] outward, one needle guard [8] is arranged on the pointer, the volute spring of a balance-like [9] the inner is connected on this rotation axis, and rack side wall one through hole is passed in its outer end, and this support [10] is a polygonal frame, establish a groove that caves inward [12] on the outer wall of the bottom of support [11], on watch back cover [2], open a through hole [21] with respect to groove, as Fig. 3, shown in Figure 4, lip-deep scale mark [13] is one section curve, the expression temperature (℃).The gear train of humidity pointer is identical with the transmission structure machine of temperature pointer, as Fig. 5, shown in Figure 6, be that humidity pointer [14] is fixed on the rotation axis [15], rotation axis has a fixed hub [16] outward, one needle guard [24] is arranged on the pointer, the volute spring of a balance-like [17], its the inner is connected on this rotation axis [15], support [18] sidewall one through hole is passed in its outer end, and this support is a polygonal frame, and a through hole is arranged on the sidewall of support, helical spring outer end is passed, surface high scale line [23] is one section curve, and expression relative humidity (%RH) is established a groove that caves inward [20] on the outer wall of the bottom of support [19]; Upward open a through hole [22] with respect to groove at back table lid [2], the big I of through hole extend in the groove circular knife.
When needs are calibrated this instrument, pass the through hole that the back table covers with screwdriver, head in the groove, rotational temperature pointer transmission bracket or humidity pointer transmission bracket drive temperature or humidity gear train unitary rotation and realize calibration.Aspect service after sale, particularly in the bigger place of southern humidity drift amount, it is convenient especially that levelling is got up.
A kind of novel two pointer thermohygrometer technical specification: (1) product form: octagon 205 * 205 * 33 (mm) (2) measurement range: temperature-10 ℃~40 ℃
