[0020] Specifically, when it is necessary to move the cross bar 7 on the support rod 5 to the outside of the box body 1, the push rod 813 is pressed to overcome the elastic force of the second spring 814, and the push rod 813 contacts the inclined surface of the inclined surface block 812 and pushes the inclined surface block 812 to move downward, so that the limit plate 810 overcomes the elastic force of the first spring 811 and moves downward, so that the limit plate 810 releases the lock on the mounting plate 15. Under the elastic force of the third spring 815, the sliding rod 802 slides outward in the sliding rail 801. In the process of the sliding rod 802 sliding outward, the movable plate 817 will press the airbag 1 818 The air in airbag one 818 is squeezed and gradually enters airbag two 826 through air duct 820. Under the action of throat contraction tube 821 and rotating ring 822 on air duct 820, rotating ring 822 moves on throat contraction tube 821 by rotating, so that throat contraction tube 821 squeezes air duct 820, reduces the cross-sectional area of ​​air duct 820, and reduces the flow speed of gas in air duct 820, so that sliding rod 802 moves at a constant speed under the push of spring three 815, and finally moves adjustment sleeve 6 on mounting plate 15 to the outside of box body 1.

[0021] In specific application scenarios, the uniform extension module 8 is mainly suitable for the uniform extension link in the uniform extension process, that is, the uniform extension module 8 uses the extrusion effect of the throat contraction tube 821 and the rotating ring 822 on the air guide tube 820 to increase the resistance of the gas from the airbag 1 818 to the airbag 2 826, so that the spring three 815 can effectively buffer the propulsion force generated by the sliding rod 802, so that the sliding rod 802 can drive the mounting plate 15 to move at an average and reasonable speed, reducing the inertia of the sample on the mounting plate 15 caused by the instantaneous acceleration generated by the spring three 815, effectively avoiding the situation where the sample is unhooked and falls from the cross bar 7 due to inertia, reducing the impact on the sample aging test results, protecting the integrity of the sample, and improving the accuracy of the test results.

[0022] It should be noted that the limit plate 810 can lock and unlock the mounting plate 15 by using the push rod 813 and the inclined block 812, so that the operator can come into contact with the high-temperature components in the box body 1, avoiding burns to the personnel and protecting the safety of the personnel.

[0023] Reference Figure 6 and Figure 7 In a preferred embodiment, circular notches are provided on the three adjustment sleeves 6, and the inner walls of the circular notches are rotatably connected to the outer sides of the fastening bolts 901 through external threads, and multiple cross bars 7 are provided with multiple equidistantly distributed cut grooves 903, and the inner walls of the cut grooves 903 are slidably connected to the outer sides of the rotating pieces 902, and the cut grooves 903 are connected to round rods through bolts, and the outer sides of the round rods are connected to torsion springs 904 through bolts, and the outer sides of the torsion springs 904 away from the round rods are connected to the outer sides of the rotating pieces 902 on the same side through bolts; the bottoms of the multiple rotating pieces 902 are connected to contact plates 905 through bolts, and the cross bars 7 are provided with strip grooves 906, and the inner walls of the strip grooves 906 are slidably connected to the outer sides of the rotating pieces 902. A long rod 907 is dynamically connected, and the upper side of the long rod 907 is bolted with a plurality of equally spaced transmission plates 908, the outer sides of the transmission plates 908 are in contact with the outer sides of the contact plates 905 on the same side, and the outer sides of the long rods 907 are bolted with springs 909, and the ends of the springs 909 away from the long rods 907 are bolted with the inner walls of the strip grooves 906 on the same side; the bottoms of the plurality of long rods 907 are bolted with bumps 910, and the outer sides of the cross bars 7 are rotatably connected with locking hooks 911 through bearings, the outer sides of the locking hooks 911 are clamped with the outer sides of the bumps 910 on the same side, and the bottoms of the long rods 907 are bolted with locking hooks 911.

[0024] Specifically, before hanging the sample on the cross bar 7, press the locking hook 911 to rotate the locking hook 911 and release the lock on the protrusion 910. Under the push of the spring four 909, the long rod 907 moves away from the adjusting sleeve 6, so that the transmission plate 908 on the long rod 907 no longer presses the contact plate 905. Under the torsion of the torsion spring 904, the rotating piece 902 rotates ninety degrees, and the sample is hooked on the side of the rotating piece 902 close to the support rod 5 to start the aging test. After the test is completed, use your fingers to hook the locking hook 911 and pull it in the direction of the adjusting sleeve 6, so that the protrusion 910 on the long rod 907 is hooked with the locking hook 911 again, and the transmission plate 908 pushes the rotating piece 902 connected to the contact plate 905 to overcome the torsion of the torsion spring 904 and reset it to be hidden in the groove 903.

[0025] In specific application scenarios, the stable hooking module 9 is mainly suitable for the stable hooking link in the stable hooking process, that is, the stable hooking module 9 uses the long rod 907 and the rotating plate 902 to keep the sample in this position after being hung on the cross bar 7, so that when the driving motor 806 drives the cross bar 7 to rotate, the centrifugal force generated will not make the tests on the same cross bar 7 fit together, ensuring the spacing between the samples, allowing hot air to circulate smoothly, and ensuring the aging test effect of the samples.

[0026] An aging test method for non-metallic parts of an internal blowout prevention tool, using the above-mentioned non-metallic parts aging test tool for an internal blowout prevention tool, comprises the following steps: Step 1: Open the box door 2, use the uniform extension module 8 to pull the mounting plate 15 out of the box body 1, so that the support rod 5 and the cross bar 7 on the mounting plate 15 can come to the outside of the box body 1, use the stable hook module 9 to rotate and unfold the rotating piece 902, hang the sample on the rotating piece 902 on the cross bar 7, push the mounting plate 15 back into the box body 1, and close the box door 2 (when it is necessary to move the cross bar 7 on the support rod 5 to the outside of the box body 1, overcome the elastic force of the spring 2 814 to press the push rod 813, the push rod 813 contacts the inclined surface of the inclined surface block 812 and pushes the inclined surface block 812 to push ... The surface block 812 moves downward, so that the limit plate 810 overcomes the elastic force of the spring 1 811 and moves downward, so that the limit plate 810 releases the lock on the mounting plate 15. Under the elastic force of the spring 3 815, the sliding rod 802 slides outward in the sliding rail 801. During the sliding outward sliding of the sliding rod 802, the movable plate 817 squeezes the airbag 1 818, so that the gas in the airbag 1 818 gradually enters the airbag 2 826 through the air guide tube 820. Under the action of the throat shrinkage tube 821 and the rotating ring 822 on the air guide tube 820, the rotating ring 822 is pressed against the airbag 1 818. By rotating, the throat shrinkage tube 821 moves, so that the throat shrinkage tube 821 squeezes the air guide tube 820, so that the cross-sectional area of ​​the air guide tube 820 is reduced, and the flow speed of the gas in the air guide tube 820 is reduced, so that the sliding rod 802 moves at a constant speed under the push of the spring three 815, and finally the adjustment sleeve 6 on the mounting plate 15 moves to the outside of the box body 1. Before hanging the sample on the cross bar 7, the locking hook 911 is pressed to rotate the locking hook 911 and release the lock of the protrusion 910. Under the push of the spring four 909, the long rod 907 moves away from the adjustment sleeve 6. The rotating piece 902 is rotated 90 degrees under the torsion force of the torsion spring 904, and the sample is hooked on the side of the rotating piece 902 close to the support rod 5 to start the aging test. After the test is completed, the locking hook 911 is hooked with the finger and pulled in the direction of the adjustment sleeve 6 to re-hook the protrusion 910 on the long rod 907 with the locking hook 911, and the transmission plate 908 pushes the rotating piece 902 connected to the contact plate 905 to overcome the torsion force of the torsion spring 904 and reset and hide in the cut groove 903); Step 2: Start the heating wire 13 and the fan 12, so that the fan 12 circulates the air heated by the heating wire 13 in the box 1, and start the drive motor 806, so that the drive motor 806 drives the support rod 5 to rotate, so that the hot air in the box 1 blows the sample.
