[0041] Upper clamping plate 15: A through slot is formed through the middle of the upper clamping plate 15. The upper clamping plate 15 is integrally formed, and a through slot is formed in the middle. A closing component is provided inside the through slot. A connecting component for connecting with the upper clamping plate 15 is provided inside the detection box 1;

[0042] Lower clamping plate 14: A rectangular opening 21 is provided in the middle of the lower clamping plate 14, and an electric push rod 13 for driving the lower clamping plate 14 to rise and fall is provided on the inner bottom surface of the detection box 1. The lower end of the electric push rod 13 is fixedly connected to the inner bottom surface of the detection box 1, and the telescopic end of the electric push rod 13 is fixedly connected to the lower end surface of the lower clamping plate 14. Two electric push rods 13 are provided and are symmetrically distributed. Marking components for marking the insulation board that has completed the inspection are provided on both sides of the upper end of the lower clamping plate 14;

[0043] The upper clamping plate 15 and the upper part of the interior of the detection box 1 form a first cavity, and a heater 5, a refrigerator 6 and a first temperature sensor 7 are arranged inside the first cavity. The heater 5, the refrigerator 6 and the first temperature sensor 7 are electrically connected to the controller 3 respectively. The heater 5 is fixedly connected to the inner wall of the first cavity by bolts. The refrigerator 6 is arranged on the top surface of the first cavity. The heater 5 is arranged to be symmetrically distributed. The heater 5 and the refrigerator 6 work in coordination to adjust and change the temperature inside the first cavity. The first temperature sensor 7 is fixedly connected to the inner wall of the first cavity by bolts. The first temperature sensor 7 is used to monitor the temperature inside the first cavity in real time. The lower clamping plate 14 and the lower part of the interior of the detection box 1 form a second cavity, and a second temperature sensor 10 is provided inside the second cavity. The second temperature sensor 10 is electrically connected to the controller 3, and the second temperature sensor 10 is fixedly connected to the inner wall of the second cavity by bolts. The second temperature sensor 10 is used to monitor the temperature inside the second cavity in real time. The second temperature sensor 10 measures data and feeds it back to the controller 3. The processor inside the controller 3 accurately calculates the data to obtain the insulation performance parameters of the insulation board, and displays them on the display screen. Extrusion components that cooperate with the marking components to squeeze the box door 2 to open it are respectively provided on both sides of the upper clamping plate 15.

[0044] Furthermore, the connecting component includes two fixed plates 12 symmetrically arranged on the inner wall of the detection box 1, and the two fixed plates 12 have chamfered corners at opposite ends. The upper ends of the upper clamps 15 are connected to the lower end surfaces of the fixed plates 12 through connecting springs 19, and the inner wall of the detection box 1 is provided with a fixed frame 11 for limiting the upward movement of the upper clamps 15. The upper surface of the fixed frame 11 is covered with a sealing coating, and a sealing gasket matching the upper clamps 15 is embedded at the lower end of the fixed frame 11. After the upper clamps 15 are abutted against the fixed frame 11, the sealing and heat-insulating effect of the upper clamps 15 and the fixed frame 11 is guaranteed. The upper end of the upper clamps 15 is provided with a sealing frame 16 that is in sliding contact with the inner wall of the fixed frame 11. The sealing frame 16 is made of rubber material and is in close contact with the inner wall of the fixed frame 11, thereby ensuring the sealing and heat-insulating effect between the sealing frame 16 and the fixed frame 11.

[0045] Furthermore, the closing component includes two closing plates 17. When the two closing plates 17 are closed to each other, the through-mouth groove is closed to prevent the through-mouth groove from always being in a connected state, that is, the first cavity and the second cavity are in a connected state. After the detection is completed, the heat preservation plate is taken away, which is easy to cause the temperature in the first cavity to change rapidly. The two closing plates 17 are hingedly matched with the upper end surface of the upper clamping plate 15 through a reset hinge. The upper ends of the two closing plates 17 are provided with an inclined plate 20 matched with the fixed plate 12. The stiffness coefficient of the connecting spring 19 is greater than the stiffness coefficient of the reset hinge. When in use, the heat preservation plate to be tested is first placed on the lower clamping plate 14, The rectangular opening 21 is covered, and then the electric push rod 13 is started to extend. The extension of the electric push rod 13 drives the lower clamping plate 14 to move upward. The upward movement of the lower clamping plate 14 drives the insulation plate to be detected to move upward, so that the insulation plate to be detected and the upper clamping plate 15 are close to each other. When the insulation plate to be detected and the upper clamping plate 15 are in contact with each other, the electric push rod 13 continues to extend, which will cause the upper clamping plate 15 to move upward, and then the connecting spring 19 is gradually compressed. In this process, the upward movement of the upper clamping plate 15 will drive the closing plate 17 and the inclined plate 20 to move upward, so that the inclined plate 20 and the fixed plate 12 produce relative displacement (refer to the attached manual Figure 4 ), since the inclined plate 20 is separated from the fixed plate 12, the closing plate 17 will flip upward under the action of the reset hinge, so that the through-mouth groove is in a connected state, ready for subsequent inspection. On the contrary, when the inspection is completed, the electric push rod 13 is started to contract, and the contraction of the electric push rod 13 drives the lower clamping plate 14 to move downward, and under the reset action of the connecting spring 19, the upper clamping plate 15 moves downward. In this process, the inclined plate 20 will gradually approach the fixed plate 12. Under the extrusion cooperation of the inclined plate 20 and the fixed plate 12, the closing plate 17 flips downward to close the through-mouth groove, thereby avoiding the heat in the first cavity from being easily lost through the through-mouth groove after the insulation plate is taken out.

[0046] Further, the marking assembly includes a deflection plate 22 and a fixed side plate 24 arranged at the upper end of the lower clamping plate 14. One end of the deflection plate 22 is rotatably connected to the fixed side plate 24 through a connecting shaft 25. The connecting shaft 25 is rotatably connected to the fixed side plate 24 through a bearing. A mounting hole for mounting the connecting shaft 25 is reserved on the fixed side plate 24. A torsion spring 27 is provided at the rotation connection between the fixed side plate 24 and the deflection plate 22. Under the action of the torsion spring 27, the deflection plate 22 is in an inclined state (refer to the attached manual). Figure 8 ), the other end of the deflection plate 22 is provided with a rotating wheel 23, the surface of the deflection plate 22 is elastically connected with a compression rod that cooperates with the fixed side plate 24, the compression rod includes a slide bar 33 that movably penetrates the deflection plate 22 and a compression block 31 arranged at one end of the slide bar 33, the compression block 31 is hemispherical, the compression block 31 is connected to the surface of the fixed side plate 24 through a second compression spring 32, one end of the compression rod is elastically connected with a marking pen 26, one end of the marking pen 26 is formed with a mounting cavity and is sleeved on one end of the slide bar 33, the slide bar 33 is connected to the inner wall of the mounting cavity through a first compression spring 30, when in use, the lower splint 14 moves upward to approach the upper splint 15, when the insulation board to be detected contacts the lower end surface of the upper splint 15, at this time The rotating wheel 23 is located below the fixed frame 11. As the lower clamping plate 14 continues to move upward, driving the upper clamping plate 15 to move upward so that the connecting spring 19 is compressed, the contact between the rotating wheel 23 and the lower end surface of the fixed frame 11 will be limited, and then continued upward movement will cause the deflection plate 22 to deflect. The deflection of the deflection plate 22 drives the pressure rod and the marking pen 26 to revolve. When the pressure block 31 in the pressure rod contacts the fixed side plate 24, the marking pen 26 will move to one side of the insulation board and contact the side wall of the insulation board. Then, as the marking pen 26 revolves, it will mark the side of the insulation board, that is, after the insulation board is inspected, the inspected side of the insulation board will be marked to avoid repeated inspections and affect work efficiency.

[0047] Further, the extrusion assembly includes a mounting plate 34 fixed to the side wall of the upper clamping plate 15 and a fixing block 38 provided at the upper end of the mounting plate 34. A slide plate 39 squeezed by the rotating wheel 23 is elastically connected to one side of the fixing block 38. One side of the slide plate 39 is connected to the surface of the fixing block 38 through a third compression spring 37. The integrally formed side wall of the slide plate 39 has a notch. A slide groove 35 for sliding connection of the slide plate 39 is provided through the surface of the mounting plate 34. An extrusion rod 36 for extruding the box door 2 is fixedly provided on one side of the slide plate 39. A through hole is provided on the fixing block 38 for the extrusion rod 36 to slide through. One end of the extrusion rod 36 is hemispherical. When in use, after the insulation board is detected, the electric push rod 13 contracts to drive the lower clamping plate 14 to move downward (refer to the attached manual Figure 3), the lower clamping plate 14 moves downward to drive the deflection plate 22 to move downward, and the deflection plate 22 moves downward to drive the rotating wheel 23 to move downward, so that the lower surface of the rotating wheel 23 contacts the upper surface of the mounting plate 34, and then due to the downward movement of the upper clamping plate 15, when the closing plate 17 is closed, the inclined plate 20 abuts against the fixed plate 12 (refer to the attached manual). Figure 4 ), which limits the downward movement of the upper clamping plate 15, that is, limits the downward movement of the mounting plate 34. Therefore, after the lower surface of the rotating wheel 23 contacts the upper surface of the mounting plate 34, the electric push rod 13 continues to contract, which will cause the deflection plate 22 to gradually deflect into a vertical state, that is, a horizontal displacement is generated between the deflection plate 22 and the mounting plate 34, and then the slide plate 39 is squeezed to make the slide plate 39 move. The movement of the slide plate 39 drives the squeezing rod 36 to move, and the squeezing rod 36 moves to squeeze the box door 2, so that the box door 2 is automatically opened, which is convenient for the staff to take and put the insulation board.

[0048] Furthermore, a fixing ring 28 is fixedly provided on one side of the deflection plate 22, one end of the torsion spring 27 is fixedly engaged with the surface of the fixed side plate 24, and the other end of the torsion spring 27 is in a suspended state. An arc groove 29 is provided on the surface of the fixing ring 28 to match the suspended end of the torsion spring 27. In the process of the deflection plate 22 gradually deflecting to a vertical state (refer to the appendix of the specification), Figure 8 With the instruction manual Fig. 9 ), the deflection of the deflection plate 22 will not cause the torsion spring 27 to be deformed by force in the reverse direction, thereby avoiding damage to the torsion spring 27. When the deflection plate 22 deflects in the reverse direction, the torsion spring 27 will be deformed by force under the cooperation of the arc groove 29 and the torsion spring 27, thereby preparing for the subsequent deflection and resetting of the deflection plate 22.

[0049] Furthermore, a base 4 is provided at the lower end of the detection box 1, a supporting foot is provided at the lower end of the base 4, and a universal wheel is provided at the lower end of the base 4. A mounting block 8 is fixedly provided on the inner bottom surface of the detection box 1. The setting of the mounting block 8 can effectively reduce the space size inside the second cavity and improve the detection sensitivity of the second temperature sensor 10. The size of the mounting block 8 is smaller than the size of the rectangular opening 21. A plurality of driven rollers 9 are rotatably provided on the upper end of the mounting block 8. When the electric push rod 13 drives the upper end surface of the lower clamping plate 14 to be lower than the height of the upper surface of the driven roller 9, the insulation board is placed on the driven roller 9 at this time, which is convenient for the staff to take and place the insulation board more labor-saving.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
