Summary of the invention
The purpose of this utility model is the problem that multiple occasion ornaments are placed in order to solve bimetallic system cell and to use, and a kind of reasonable in design is provided, and can hang, can put, can receive, the collapsible bimetallic system cell of conveniently moving.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of collapsible bimetallic system cell, it is characterized in that comprising the lower carrier plate and the upper supporting plate that are hinged, in described upper supporting plate, be provided with watchcase, bi-metal plate shape body is housed in watchcase, in a dial front, establishes a pointer and be connected with thermometal plate-like body.Bimetallic system cell is to utilize material when temperature variation, and its resistance is also measured temperature along with the feature changing, and when change in resistance, work instrument just demonstrates the corresponding temperature value of resistance.In order to adapt to the practicality of present technique, the thermometal thermo-sensitive material of this device is designed to discoid element, in short cylindrical shape watchcase volume functor as thermometal plate-like body, dial, pointer setting wherein, and by window reading, by lower carrier plate and upper supporting plate are folding, form one and can pack up and put, also can as suspension member, furnish by lower carrier plate.
As preferably, in the middle part of described lower carrier plate, be provided with through hole, watchcase front is provided with watch glasses, and described lower carrier plate through hole is greater than the physical dimension of watch glasses.Both can alleviate lower carrier plate weight, and can utilize again through hole to mount.When packing up, lower carrier plate can be integrated by articulated section and upper supporting plate.
As preferably, in described watchcase, be provided with element frame, thermometal plate-like body is connected with dial by element frame.General thermometal plate-like body need to be fixed installation by element frame, to keep the normal operation of thermometal plate-like body.
As preferably, described dial center is provided with central shaft, and thermometal plate-like body is connected with pointer by central shaft.Bimetallic system cell principle of work is the multilayered metal film that forces together and form with two or more metal film stacks, utilize two kinds of different metals degrees of expansion different operating when temperature change, thermometal plate-like body passes to pointer by central shaft this variable quantity.
As preferably, described lower carrier plate and the articulated section of upper supporting plate are provided with anglec of rotation position limiting structure.When vertical placement, this device is supported by lower carrier plate, so lower carrier plate is along upper supporting plate reverse rotation one angle, as 120 when spend, by anglec of rotation position limiting structure restriction location, to reach the best observation angle of pointer and dial.
As preferably, on the described watchcase that is positioned at pointer top, perspective table window is housed.Perspective table window adopts transparent material to make, and can protect the safety of pointer.
As preferably, described perspective table window is fixed in upper supporting plate by watch glasses.Watch glasses installation and the replacing that facilitates perspective table window be set.
As preferably, described watchcase bottom is provided with air vent.Air vent not only can dispel the heat, and can also make thermometal plate-like body directly contact surveyed environment temperature.
Effective effect of the present utility model is: on-the-spot displays temperature, and intuitive and convenient, safe and reliable, long service life rational in infrastructure; Can be placed directly on table top and on end use, also can mount use.
