When the preset value is reached, the PLC controller 13 controls the multi-stage electric telescopic rod 12 to automatically close, which facilitates the effect of automatically and accurately adjusting the touched height according to the bending requirements of different building boards.

[0030] The method of using this embodiment is as follows: when testing the bending strength of a building board by extrusion, first place the building board on top of the four supporting rollers 7, then start the electric push rod 3 in the positive direction to drive the U-shaped rod 4 to move downward, and the U-shaped rod 4 drives the pressure block 6 to move downward through the pressure detector 5. At the same time, the U-shaped rod 4 drives the four pressing plates 10 downward to squeeze the building board through the four first springs 9 and the four T-shaped guide rods 8 in turn. In the extrusion state, the pressing plate 10 is blocked and restricted by the building board. At this time, the U-shaped rod 4 that continues to move downward slides downward on the four T-shaped guide rods 8 and stretches the first spring 9. The elastic force generated by the stretching of the first spring 9 is used to tighten and press the building board. The pressure block 6 that continues to move downward impacts and extrude the building board. During the extrusion test, the pressure detector 5 detects and displays the test pressure value to realize the bending strength test of the building board by extrusion. Combined with the method of automatically tightening and pressing the building board during the downward extrusion test, an integrated automatic fixation is realized, and there is no need for personnel to perform fixing operations separately, thereby improving the fixing efficiency and convenience of use.

[0031] When the building board is bent downward due to the impact of squeezing, the building board presses the touch switch 16 downward to touch the touch switch 16, and the touched touch switch 16 transmits an alarm signal to the PLC controller 13. The PLC controller 13 controls the sound and light alarm 20 to start the alarm to remind the personnel, so as to achieve the effect of automatically and promptly reminding the personnel when the building board is squeezed and bent beyond the requirement. By means of automatic alarm, the detection accuracy is improved and the phenomenon of misjudgment by traditional manual observation is reduced;

[0032] When it is necessary to adjust the touched height according to the bending requirements of different plates, the PLC controller 13 is used to pre-set the spacing value of the multi-stage electric telescopic rod 12 according to the bending requirements of different building plates. Then, the multi-stage electric telescopic rod 12 is turned on to drive the rectangular tube 14 to move down or up. The rectangular tube 14 drives the touch switch 16 to move down or up through the second spring 17 and the T-shaped rod 15 in turn, changing the touched height position during detection. When the rectangular tube 14 moves, it also drives the reflective sheet 19 to move down and up. The laser distance sensor 18 measures the distance with the reflective sheet 19 in real time. The spacing between the two is transmitted to the PLC controller 13. When the preset value is reached, the PLC controller 13 controls the multi-stage electric telescopic rod 12 to automatically close, so as to achieve the effect of automatically and accurately adjusting the touched height according to the bending requirements of different building boards, thereby improving the scope of application. The second spring 17 is set so that when the building board bends downward and squeezes the touch switch 16 to move downward as a whole, the touch switch 16 drives the T-shaped rod 15 to move downward and compress the second spring 17. The compressible characteristic of the second spring 17 can achieve the effect of elastic avoidance and prevent hard collision.

[0033] After the detection is completed, when the electric push rod 3 is started in reverse to drive the U-shaped rod 4 to rise, the U-shaped rod 4 drives the pressure block 6 to rise through the pressure detector 5, and releases the tensile force on the first spring 9. After the tensile force is released, the U-shaped rod 4 that continues to move upward drives the pressure plate 10 to rise through the first spring 9 and the T-shaped guide rod 8 in turn, thereby achieving the effect of automatic unfastening after detection.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
