The effect of described U-shaped glass tube 1 is to be used for storing temperature sensing liquid, and when temperature sensing liquid expanded or shrink, transfer liquid was followed moving of temperature sensing liquid and moved, thereby push pointer moves; The effect of scaleplate 5 is to be used for fixing U-shaped glass tube 1, and printing scale numerical value; Described printing scale 6 is used to refer to current temperature value and the highest and minimum temperature value; Described magnetic stripe is used for attracting the pointer of U-shaped glass tube 1, thus the highest or minimum of record; Described spring can make magnetic stripe be close to scaleplate 5 back sides; Described loam cake 10 is used for fixing U-shaped glass tube 1 and scaleplate 5; Described bottom 11 is as the supporting surface of spring, and is fixed on the loam cake 10.
Assembly relation of the present utility model carries out according to following steps:
1) before glass tube is made U-shaped, drain clean capillary inner air tube, temperature sensing liquid is poured in down a chimney in the pipe, by covering liquid, excess liquid is flowed out, put into pointer, the glass tube stage casing is heated with high temperature, bend to the U-shaped pipe of solid shape with anchor clamps, after cooling, inject transfer liquid with syringe again, and then add temperature sensing liquid and put into pointer, then end socket.
2) the U-shaped pipe that will inject temperature sensing liquid and transfer liquid is put into 10 ℃, 40 ℃ Water Tanks with Temp.-controlled, marks out two temperature spot positions, measures distance.
3) scale printing: by to the expansivity of temperature sensing liquid, the calculating that capacity and 10 ℃, 40 ℃ distances are steeped in the glass tube termination, draw temperature scale, make version, be printed on scaleplate 5 both sides.
4) watch core assembling: according to different watch core distances, selects identical scale to assemble, 10 ℃ with 40 ℃ of lines will with aligned in position accordingly on the scale mark, be fixed on the scaleplate 5 with glue.
5) magnetic stripe assembling: two magnetic stripe back side Double-face gummed papers are torn, be attached on the press strip 9 that resets.
6) scaleplate assembling: the scaleplate 5 that will assemble watch core is placed on the loam cake 10 conversely, can not be inverted up and down.
7) press strip assembling: the press strip 9 that will post magnetic stripe oppositely is placed on the scale backboard, and middle button is passing scaleplate 5.
8) spring assembling: with spring minor diameter circle down, be stuck on the breach at press strip 9 back sides.
9) bonnet assembling: bonnet 11 is covered on loam cake 10, bonding with glue.
Before the use, the button by middle can make magnetic stripe and scaleplate 5 back sides on the press strip 9 that resets form certain distance, thereby makes pointer can not get attractive force on the magnetic stripe, and under action of gravity, free-falling is owing to the density of transfer liquid is 1.5g/cm
3, the gravity of pointer stops so pointer falls to the upper end of transfer liquid less than the surface tension of transfer liquid; Release button resets press strip 9 under the acting force of spring, is close to scaleplate 5 back sides, thereby makes magnetic stripe also be close to scaleplate 5 back sides, makes pointer be subjected to magneticaction.
Because the two-end structure of U-shaped pipe 1 is different, left end is a right cylinder bulb,, the about 6ml of capacity, and temperature sensing liquid is full of wherein; The about 2ml of ball capacity of right-hand member, and certain air is arranged in the cone of upper end.
Principle of work of the present utility model is as follows: when temperature rises, the temperature sensing liquid at two ends, the left and right sides all can expand, but owing to the left end full of liquid does not have air, so must move down along kapillary, and right-hand member has air, the pressure that the temperature sensing liquid expansion produces dwindles volume of air, so when temperature raises, the temperature sensing liquid on U-shaped pipe 1 left side moves down, and the temperature sensing liquid of right-hand member moves up under the promotion of transfer liquid.
The pointer on the left side stops in the middle of the temperature sensing liquid, and can not descend along with the decline of temperature sensing liquid owing to be subjected to the effect of magnetic stripe magnetic force at this moment; The pointer on the right also has been subjected to the magneticaction of magnetic stripe, but magnetic force is less than the expulsive force of transfer liquid, so transfer liquid can push pointer move up.
When temperature is increased to peak (as 35 ℃), the scale of the temperature sensing liquid lower end correspondence of the right and left should be 35 ℃, the lower end of right-hand member pointer also rests on 35 ℃ of lines, and the right of transfer liquid also rests on 35 ℃ of lines topmost, and 35 ℃ of indicated lines of pointer lower end this moment are maximum temperature value; When temperature descends, left end temperature sensing liquid volumetric contraction, temperature sensing liquid moves up, transfer liquid moves to the upper end simultaneously, and the temperature sensing liquid and the transfer liquid of right-hand member move down, because the effect of magnetic force, the pointer of right-hand member can rest in the middle of the temperature sensing liquid, and does not move with liquid; The pointer of left end can move up under the promotion of transfer liquid, because thrust adds pointer gravity greater than attractive force; When (as-10 ℃), the temperature sensing liquid lower surface at two ends, the left and right sides and the upper surface of transfer liquid are all indicated-10 ℃ of scale mark positions when temperature is reduced to minimum, and the pointer lower end of left end is also in this position; When temperature is (as 20 ℃) between-10 ℃ and 35 ℃ the time, the pointer at two ends is through the effect of the highest temperature and lowest temperature, being transferred liquid is pushed to the highest and the minimum temperature point, under the effect of magnetic stripe attractive force, rest on this 2 point, so maximum temperature and the minimum temperature that can notify the temperature value of read pointer lower end to know that this thermometer is measured.Pointer lower end, the left side is shown as the minimum temperature value; Pointer lower end, the right is shown as maximum temperature value.
Whenever, the pairing scale value in temperature sensing liquid lower end, two ends is a current temperature value.
By the button of middle-end, make magnetic stripe and scaleplate 5 produce certain distance, the attractive force of magnetic stripe is less than pointer gravity, and pointer drops on the transfer liquid upper end, promptly is equivalent to the highest minimum temperature value and resets.
Can carry out the thermometric and the record of a new round.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
