As shown in figure 4, control unit 21 has been also coupled in response to control signal and for indicating whether pressure testing machine is located
In that can be activated the indicating member 23 of state, indicating member 23 includes relay KA normally opened contact KA-2 and light emitting diode
LED, relay KA normally opened contact KA-2 one end are coupled to voltage V2, and the other end is coupled to the anode of LED,
The minus earth of LED.
Specific work process is as follows：
When using pressure testing machine, test specimen is first installed correct, then closes the sideboard 4 on two feed rods 3 respectively,
Until two pieces of sideboards 4 are connected on each self-corresponding limited block 24 respectively, so that the plate face of two pieces of sideboards 4 is in
Same plane.Drive the first lockplate 9 to turn in the holding tank of holder 10 by handle 18 again, make under the first lockplate 9
Edge abuts the upper surface of supporting plate 11, while compressing plate 12 is connected to the side away from sideboard 4 on the first lockplate 9.
When the first lockplate 9 is during rotation, the second lockplate 15 is also synchronous to be rotated, and it is connected to another piece of activity
The medial surface of baffle plate 4, so that the sideboard 4 of holder 10 will be provided with by the first lockplate 9 and the second lockplate 15
Position restriction is lived, and to limit the position of two pieces of sideboards 4, sideboard 4 is not opened.
Now, because magnetic part 19 is close to detection unit 20, Hall sensor H1 is made to be able to detect that magnetic part 19
Magnetic field, so as to export the detection signal of high level to triode Q1 base stage by resistance R1, turns on triode Q1, relay
KA coil obtains electric adhesive, and its corresponding normally opened contact KA-1 and KA-2 is all closed, if at this moment closing control button SB, pressure
Testing machine can normally start, and LED lights and pointed out.Test specimen sputters what is come during crushing
Fragment can be lived by sideboard 4 and the barrier of fixed dam 5, it is ensured that security.
If the first lockplate 9 is not buckled among holder 10 after sideboard 4 is closed, Hall sensor H1
The magnetic field of magnetic part 19 is can't detect, so as to export low level detection signal to triode Q1 base stage by resistance R1, is made
Triode Q1 ends, and relay KA coil is in power failure state, and its corresponding normally opened contact KA-1 and KA-2 all disconnects, with
The current supply circuit of cut-out pressure testing machine and LED respectively, if at this moment closing control button SB, pressure testing machine without
Method starts, and LED does not also light.
After pressure testing machine experiment is finished, then the portion by handle 18 being connected to the first lockplate 9 on supporting plate 11
Divide and be retracted among corresponding sideboard 4, while the second lockplate 15 has also carried out corresponding rotation, at this moment just can release two
The locking of block sideboard 4, enables sideboard 4 to be opened again.
