The sample rack 2 is composed of a frame 28, a top plate 21 with a lifting rod 5, an adjustment plate 22, and an adjustment screw assembly. The top plate 21 and the adjustment plate 22 are stuck in the frame 28, and the frame 28 is used to be placed on a support table on the inner wall of the box body 1, and the side wall of the frame 28 is close to the inner wall of the box body 1. A plurality of rows of strip grooves 20 are arranged on the top plate 21 of the sample placement rack 2, and a through hole 4 communicating with the solution storage part is arranged next to each strip groove 20; an adjustment plate 22 is arranged below the top plate 21 of the sample placement rack 2, and a plurality of arc-shaped columns 23 are arranged on the adjustment plate 22; an arc-shaped groove 24 is arranged on the side wall of the strip groove 20, and the arc-shaped columns 23 on the adjustment plate 22 can be inserted into the arc-shaped groove 24; the strip groove 20 is used to place strip-shaped pyrotechnic test products, and when the top wall of the arc-shaped column 23 on the adjustment plate 22 is lower than the upper surface of the top plate 21, the space directly above the arc-shaped column 23 is used to place the columnar pyrotechnic test product.

[0024] In this embodiment, an adjusting screw 25 is connected to the adjusting plate 22, and a circular limit platform 29 is provided at the bottom of the adjusting screw 25. The limit platform 29 is just located in the circular groove at the bottom of the adjusting plate 22, and the bottom wall of the limit platform 29 is flush with the bottom wall of the adjusting plate 22. The lower part of the adjusting screw 25 passes through the hole on the adjusting plate 22 and is loosely matched with the hole. The adjusting screw 25 threadably matches the top plate 21 and penetrates the top plate 21. When the adjusting screw 25 is turned clockwise, the adjusting plate 22 is driven to move upward, and when the adjusting screw 25 is turned counterclockwise, the adjusting plate 22 moves downward; and when the adjusting screw 25 is turned clockwise to make the adjusting plate 22 in the upper limit position, the top wall of the arc column 23 is flush with the upper surface of the top plate 21.

[0025] In this embodiment, a circular hole 27 is provided on the bottom wall of the strip groove 20, and the hole wall of the circular hole 27 and the groove wall of the arc groove 24 are located on the same circumferential surface; a notch 26 is provided between the two arc cylinders 23 for matching the two arc grooves 24 in the same strip groove 20, and the lateral opening of the notch 26 is arranged in the same direction as the length direction of the strip groove 20, and the diameter of the two arc cylinders 23 is slightly smaller than the diameter of the circular hole on the bottom wall of the strip groove 20 (in essence, a notch is opened on the cylinder, so as to form a notch as shown in FIG. Figure 3 The arc-shaped cylinder 23 shown has a diameter slightly smaller than the diameter of the circular hole on the bottom wall of the strip groove 20, and slightly smaller means that the difference in diameter between the two is 3-5 mm).

[0026] In this embodiment, the through hole 4 provided on the top plate 21 and the through hole 4 provided on the adjustment plate 22 have the same specifications and are coaxially arranged; the through hole 4 on the adjustment plate 22, the space between the top plate 21 and the adjustment plate 22, the notch 26 and the circular hole 27 together constitute a first airflow passage, that is, Figure 2 The through hole 4 on the adjustment plate 22, the space between the top plate 21 and the adjustment plate 22 and the through hole 4 on the top plate 21 together constitute a second airflow path, that is, Figure 2 The direction is indicated by the medium and long arrow.

[0027] In this embodiment, a through hole 4 is provided between adjacent strip grooves 20 in the same horizontal row; the sample placement rack 2 is placed in the middle of the box body 1, and the distance between adjacent strip grooves is 15 mm.

[0028] One of the methods of using the long-term storage environment adaptability test device for explosive pyrotechnics in this embodiment is: turn the adjusting screw 25 clockwise to move the adjusting plate 22 to the upper limit position. At this time, the top wall of the arc column 23 is flush with the upper surface of the top plate 21, and the gap 26 between the two arc columns 23 completely overlaps with the strip groove 20, which is equivalent to the arc column 23 being completely matched in the arc groove 24. The strip groove 20 is a rectangular groove, such as Figure 7 As shown; when conducting a long storage environment adaptability test, it is only necessary to place the long strip of pyrotechnics in the strip groove 20.

[0029] The second method of using the long-storage environment adaptability test device for explosive pyrotechnics in this embodiment is: turn the adjusting screw 25 counterclockwise to move the adjusting plate 22 to the lower limit position. At this time, the arc column 23 is separated from the top plate 21, which is equivalent to the arc column 23 being completely located below the circular hole 27, and the arc groove 24 on the side wall of the strip groove 20 is completely exposed; when conducting a long-storage environment adaptability test, it is only necessary to place the columnar pyrotechnics in the arc groove 24 and the circular hole 27, and support them with the help of the top wall of the arc column 23.

[0030] The third method of using the long-storage environment adaptability test device for explosive pyrotechnics in this embodiment is: turn the adjusting screw 25 counterclockwise to move the adjusting plate 22 to the position where the top wall of the arc column 23 is higher than the bottom wall of the strip groove 20 and lower than the upper surface of the top plate 21. At this time, the arc column 23 is partially fitted in the arc groove 24; when conducting a long-storage environment adaptability test, first place the long strip of pyrotechnics (such as fuse) in the strip groove 20 and the notch 26 (equivalent to placing the long strip of pyrotechnics in the strip groove 20 and passing through the notch 26), and then place the columnar pyrotechnics (such as detonators) in the arc groove 24 and support them with the help of the top wall of the arc column 23. This case is particularly suitable for effectively and safely conducting tests on the columnar pyrotechnics and the matching long strip of pyrotechnics at the same time.

[0031] The long-storage environment adaptability test device for explosive pyrotechnics in this example has a simple and ingenious structure. It is not only suitable for long-storage environment adaptability tests on cylindrical pyrotechnics, but also suitable for long-storage environment adaptability tests on elongated pyrotechnics (including flexible or rigid elongated pyrotechnics) without replacing the sample placement rack and increasing the volume of the test device. It can also effectively and safely test both cylindrical pyrotechnics and elongated pyrotechnics at the same time, which is beneficial to improving the relevance and accuracy of the long-storage environment adaptability test results of cylindrical pyrotechnics and elongated pyrotechnics. By using the device in this example, it can be ensured that the wet atmosphere generated in the solution storage part acts on the pyrotechnics in a relatively gentle manner, and that the wet atmosphere in the test box flows relatively gently, rather than immediately acting on or even flushing the pyrotechnics. By using the device in this example, it can be quickly switched to a state suitable for placing different types of pyrotechnics, and it can be ensured that the wet atmosphere acts on the pyrotechnics from multiple directions, and blind spots in the test can be avoided as much as possible. In addition, the length of arc column 23 extending into circular hole 27 and arc groove 24 can be flexibly adjusted according to the specifications of the pyrotechnics, which is suitable for the long-storage environment adaptability test of most conventional pyrotechnics.
