Description

[Detailed description of the invention] This invention relates to an improvement of a thermometer holder for measuring the internal temperature of a rubber-like substance such as a tire.

Conventionally, a thermometer holder as shown in FIG. 1 has been used to measure the internal temperature of a tire, for example, in a tire running test.

In the figure, reference numeral 1 denotes a needle-like temperature-sensing section, in which a thermocouple is housed, and is fixed to the holder main body 2.

When measuring temperature, the temperature sensing part 1 is inserted into the area to be measured, and the electromotive force generated in that state is sent to the separately provided thermometer body via the compensating conductor 3, where it is converted into temperature. It will be displayed and you can read it.

Therefore, when many objects to be measured are located widely apart,
Carrying around the thermometer itself is very inconvenient.

Therefore, a relatively easy idea is to extend the compensating lead wires near each object to be measured and connect them to the holder via a connector.

However, when there are many objects to be measured and many measurement points, the work is time-consuming and cannot be done by only one worker.

The object of this invention is to provide a thermometer holder that can solve the above-mentioned conventional problems.

This invention will be explained below based on one embodiment shown in the drawings.

FIG. 2 shows a thermometer holder 10 according to an embodiment. Similar to the conventional thermometer holder 10 shown in FIG. .

The difference from the one in FIG. 1 is that the holder main body 2 is provided with a push button switch 11, and two conductive wires 1
2 is drawn out to the outside together with the compensation conductor 3.

A push button 13 serving as an operation part of the switch 11 is provided at an upper position where it can be pressed with the thumb while holding the holder main body 2 and inserting the temperature sensing part 1 into the object to be measured.

This thermometer holder 10 includes, for example, 10a in FIG.
10b, 10C, 10d using four pieces as shown and connecting them to the thermometer main body 20 having a Phnont device,
By using the switch 11 for printing commands, the work of measuring and recording the temperature can be done by one person in a short time.

Figure 3 shows a device that simultaneously tests running four tires, with tires 21a, 21b, 21C, and 21d, which are pressed against one of rotating drums 22 and 23 and rotated. .

Thermometer holders 10a, 10b, IOC, 10d, compensation lead wires 3a, 3b, 3C, 3d and lead wire 12a, respectively
, 12 b , 12 C, 12 d are connectors 24 a
, 24b.

It is connected to the thermometer main body 20 via 24C, 24d and the same conducting wire as above, and the general structure of the thermometer main body 20 is as shown in the block diagram in FIG.

In the same figure, 25 a, 25 b, 25 C, 2
5d is each thermometer holder 10a, 10b, 10
These are input terminals for position switching and print commands corresponding to C and 10d, and conductors 12 a , 12 b , and 12 , respectively.
The extension ends of C and 12d are connected.

26a, 26b, 26C, 26d are compensation conductors 3a, 3b connected to the temperature sensing part 1 of each holder.
The extension ends of 3C and 3d are connected.

Reference numerals 27 and 28 are changeover switches, the changeover switch 27 takes a changeover position corresponding to the terminal to which the input is received, and the changeover switch 28 is switched in conjunction with the changeover switch 27.

Now, suppose that the thermometer holder 10a is used, its temperature sensing part 1 is inserted into the measured position of the tire 21a, and the push button 13 is pressed. The position corresponding to the holder 10H is displayed, the temperature is displayed on the display 30, and the printer 31 records the same contents as the above display.

Therefore, when an operator uses a thermometer holder corresponding to the object to be measured at a predetermined position, inserts the temperature sensing part 1 and presses the push button 13, the measured temperature is automatically recorded.
Measurement work can be carried out quickly by humans.

In the work of measuring the temperature of the four tires shown in Figure 3 at six locations for each tire, conventionally two workers would use one worker to pierce the temperature sensing part and the other to insert the temperature sensor into the body of the thermometer. When recording temperatures at a location, the average work time was about 2 minutes;
When the thermometer holder of the example was used, it took only one worker and the average working time was about 1 minute and 40 seconds.

In other words, the effect is not limited to simply having one worker;
The effect of shortening work time is also significant.
