Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] With reference to Figures 1-3 The utility model provides an embodiment: a kind of high-low pressure magnesium-based solid hydrogen storage material test box, the structure of box 1 is made of high-strength material, ensure that it has good pressure resistance and corrosion resistance, hinged joint 2 is fixedly connected at the top of box 1, hinged joint 2 one side is fixedly connected with box cover 3, box cover 3 and box 1 are connected by hinged joint 2, ensure that box cover 3 can be smoothly opened and closed, high-low pressure regulator 5 is arranged in box 1, limit slot 6 is opened in box 1, for installing and adjusting the position of separation assembly, separation assembly is arranged in box 1, connection assembly is arranged on the side of box 1;

[0035] The separation assembly includes a partition plate 7, which is slidably connected inside the box 1. A sliding groove 8 is formed inside the partition plate 7. A limiting plate 9 is slidably connected inside the sliding groove 8. A support column 10 is fixedly connected inside the partition plate 7. The limiting plate 9 is slidably connected to the outer wall of the support column 10. The limiting plate 9 is slidably connected inside the sliding groove 8, ensuring that the limiting plate 9 can slide smoothly and be stably fixed. A spring 11 is sleeved on the outer wall of the support column 10, with both ends fixedly connected inside the partition plate 7 and the limiting plate 9, respectively, to maintain the stability of the separation assembly.

[0036] Specifically, when using the test box, first, through the high-low pressure regulator 5 inside the box 1, and in cooperation with the pressure-resistant and corrosion-resistant materials of the box 1 and the box cover 3, and the partitioning of the interior space of the box 1 by the partition plate 7, the performance of the hydrogen storage material under different pressure conditions can be accurately evaluated. The high-low pressure regulator 5 can accurately control the pressure environment inside the box 1. By adjusting the gas input or output, the required test conditions are maintained, thereby ensuring the accuracy of the experimental data. When the interior space of the box 1 needs to be adjusted, first, the partition plate 7 is inserted into the box 1. In this process, the limiting plate 9 inside the partition plate 7 is extruded by the inner wall of the box 1, causing the limiting plate 9 to smoothly slide into the sliding groove 8 inside the partition plate 7. At the same time, the limiting plate 9 extrudes the spring 11 on one side, causing the spring 11 to contract. At this time, the compression of the spring 11 makes the partition plate 7 more stable with the assistance of the internal pressure. When the partition plate 7 is completely inserted into the box 1, the spring 11 unloads and rebounds, thereby pushing the limiting plate 9 into the limit slot 6 inside the box 1 to complete the fixation, thereby achieving the effect of facilitating the rapid adjustment of the interior space of the box 1.

[0038] Specifically, when it is necessary to close the box body 1, first, the box cover 3 is flipped through the hinge 2 so that the box cover 3 is closed above the box body 1 to form a tight closed structure, at the same time, the fixed plate 12 on one side of the box cover 3 is rotated to above the fixed plate 12 on one side of the box body 1, at this time, rotating the handle two 19 will drive the rotating block 18 to rotate on the outer wall of the support shaft 17, by rotating the handle two 19, the rotating block 18 drives the clasp 20 inside to displace, the clasp 20 is forced to slide into the opening 15 in the fixed block 14 to complete the fixation, the locking effect of the clasp 20 ensures the tight closure of the box body 1, not only enhances the sealing of the box body 1, but also improves the safety of the box body 1 under high pressure, finally realizes the effect of locking and sealing the box body 1 conveniently, ensures the safety during the hydrogen storage test and the accuracy of experimental data.

[0039] Working principle: when using the test box, first through the high and low pressure regulator 5 inside the box 1, and cooperate with the anticorrosion material and the partition plate 7 of the box 1 and the box cover 3 of the box 1, the performance of the hydrogen storage material under different pressure conditions can be accurately evaluated, when the space inside the box 1 needs to be adjusted, first insert the partition plate 7 into the box 1, in this process, the limiting plate 9 inside the partition plate 7 will be extruded by the inner wall of the box 1, so that the limiting plate 9 slides into the sliding groove 8 inside the partition plate 7, at the same time, the limiting plate 9 will extrude the spring 11 on one side, so that it shrinks, when the partition plate 7 is completely inserted into the box 1, at this time, the spring 11 unloads and rebounds, and then pushes the limiting plate 9 to slide into the limiting slot 6 inside the box 1 to complete the fixation, so as to achieve the effect of facilitating the adjustment of the space inside the box 1, when the box 1 needs to be closed, first turn the box cover 3 through the hinge 2, so that the box cover 3 is closed above the box 1, at the same time, the fixed plate 12 on one side of the box cover 3 is turned above the fixed plate 12 on one side of the box 1, at this time, turn the handle 19, so that it drives the rotating block 18 to rotate outside the supporting shaft 17, at the same time, the handle 19 will drive the clasp 20 inside to displace, so that the clasp 20 slides into the gap 15 inside the fixed block 14 to complete the fixation, so as to achieve the effect of facilitating the locking of the box 1.
