Detailed description of the invention
The core of the present invention is to provide a kind of pantograph pressure gauge, and this pantograph pressure gauge can improve tonometric accuracy.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Refer to the front view of the pantograph pressure gauge that Fig. 1 to Fig. 4, Fig. 1 provide for the embodiment of the present invention; Fig. 2 is the side view of Fig. 1; Fig. 3 is the top view of Fig. 1; Fig. 4 is the structural representation of upper connector in Fig. 1.
A kind of pantograph pressure gauge provided by the invention, including upper connector 1, lower connection 6 and strain gauge 201; That is, contact net 9 is disposed with upper connector 1, strain gauge 201, lower connector 6 and pantograph from top to bottom; And upper connector 1, strain gauge 201 and lower connector 6 are whole installation; And the lower domed structure of connector 6, in order to be connected with pantograph.
Carrying out in detection process to pantograph, first, pantograph pressure gauge upwards pushed up and hang on contact net, opening strain gauge 201, unit is set as N (newton) and resets; Pantograph rises, and pantograph should not encounter pantograph pressure gauge when rising; Rising after pantograph, slowly drop-down pantograph, and pantograph pressure gauge is shifted onto between two slide plates of pantograph, withstanding cross bar, keeping pressure value checking device vertical, reading record after stable about 5 seconds. When test completes, after pantograph is fallen, pull-out pantograph pressure gauge, turns off strain gauge power supply, pantograph pressure gauge and related tool is picked up and put into packing box downwards.
Adopting above-mentioned set-up mode, owing to upper connector 1, strain gauge 201 and lower connector 6 keep vertical state, therefore the reading of strain gauge can remain stable for, and improves the accuracy of measurement.
