The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] The drop test structure for an air protective case disclosed in this utility model is mainly applied to scenarios where traditional drop test structures for air protective cases mostly use clamps to hold the air protective case and then let it fall freely from a corresponding height. When performing multiple drop tests from the same height, time is required each time to adjust the clamps to hold the air protective case, which is cumbersome and results in a long time for a single drop test, affecting the efficiency of the drop test.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A drop test structure for an air protection sleeve includes a platform 1 and a mounting block 4, and further includes:

[0029] Adjustment mechanism, used to adjust the drop height;

[0030] An extension mechanism is used to improve the flexibility of the test structure;

[0031] The mounting block 4 has a square groove inside. A motor 8 is fixedly installed on one outer wall of the mounting block 4. The output shaft of the motor 8 is fixedly connected to a threaded rod 11. Two movable blocks 15 are sleeved on the outer wall of the threaded rod 11. An adjustment hole is provided on one outer wall of the movable block 15. A placement rod 9 is movably connected to one outer wall of the movable block 15 through a hinge. A sliding groove 16 is opened on the bottom outer wall of the placement rod 9. A base plate 13 is provided on one outer wall of the mounting block 4. An adapter block 17 is fixedly installed on one side of the top outer wall of the base plate 13. The movable block 15 is threadedly connected to the threaded rod 11 through the adjustment hole, and the threads of the two adjustment holes are opposite in direction.

[0032] The adjustment mechanism includes a column 2 fixedly installed on the top outer wall of the table 1. Several equally spaced slots 3 are opened on one side of the outer wall of the column 2. An adjustment block 5 is sleeved on the outer wall of the column 2. A rotating rod is movably connected to the inner wall of the adjustment block 5 through a bearing. A locking block 6 is fixedly connected to the outer wall of the rotating rod. A knob 7 is fixedly connected to one end of the rotating rod through the adjustment block 5. The locking block 6 is adapted to the slot 3. The adapter block 17 is located inside the slide groove 16. The threaded rod 11 is located inside the square groove.

[0033] The rotating rod is equipped with a tension spring structure (this structure is not shown).

[0034] In practical use, pull the adjusting block 5 upwards, and the locking block 6 will disengage from the locking slot 3. Under the action of the tension spring, the locking block 6 will automatically lock into the next locking slot 3, realizing the upward adjustment of the adjusting block 5. Slightly lift the adjusting block 5 upwards and rotate it to disengage the locking block 6 from the locking slot 3. Then pull the adjusting block 5 down, and finally, under the action of the tension spring, the locking block 6 will spring back and lock into the locking slot 3 again, realizing the downward adjustment of the adjusting block 5. After adjusting the position of the adjusting block 5 according to the drop test height, place the item wrapped in the air protective sleeve on the two placement rods 9, with its two ends resting on the two placement rods 9 respectively. The motor 8 starts, driving the threaded rod 11 to rotate, which in turn drives the two movable blocks 15 to move relative to each other. As one end of the placement rod 9 is pulled by the movable block 15, the adapter block 17 moves in the slide groove 16, thereby opening the two placement rods 9 to both sides, causing the air protective sleeve to fall. When conducting multiple drop tests at the same height, the item wrapped in the air protective sleeve can be quickly placed, and the operation can be repeated.

[0035] Reference Figure 1 and Figure 3 In a preferred embodiment, the extension mechanism includes a plurality of mounting slots 10 symmetrically opened on one side of the outer wall of the mounting block 4. Fixing blocks are fixedly connected to both sides of the outer wall of the base plate 13. A stud 12 is inserted into one side of the outer wall of the fixing block. The base plate 13 and the stud 12 are adapted to the mounting slots 10.

[0036] Specifically, when placing air protection sleeves of different sizes, the distance between the placement rods 9 needs to be matched accordingly. This is achieved by screwing out the studs 12, adjusting the initial position of the movable block 15 and the position of the base plate 13, and finally fixing them with the studs 12, thus completing the initial distance adjustment of the two placement rods 9.

[0037] Working principle: In use, pull the adjusting block 5 upwards, and the locking block 6 will disengage from the locking slot 3. Under the action of the tension spring, the locking block 6 will automatically lock into the next locking slot 3, realizing the upward adjustment of the adjusting block 5. Slightly lift the adjusting block 5 upwards and rotate it to disengage the locking block 6 from the locking slot 3. Then pull the adjusting block 5 down. Finally, under the action of the tension spring, the locking block 6 will spring back and lock into the locking slot 3, realizing the downward adjustment of the adjusting block 5. After adjusting the position of the adjusting block 5 according to the drop test height, place the item wrapped in the air protective sleeve on the two placement rods 9, with its two ends resting on the two placement rods 9 respectively. The motor 8 starts, driving the threaded rod. Rotating 11 causes the two movable blocks 15 to move relative to each other. As one end of the placement rod 9 is pulled by the movable block 15, the adapter block 17 moves within the slide groove 16, causing the two placement rods 9 to open to both sides, allowing the air protective sleeve to fall off. When performing multiple drop tests from the same height, items wrapped in the air protective sleeve can be quickly placed, and the operation can be repeated. When placing air protective sleeves of different sizes, the distance between the placement rods 9 needs to be adjusted accordingly. This is done by screwing out the stud 12, adjusting the initial position of the movable block 15 and the position of the base plate 13, and finally fixing it with the stud 12, thus completing the initial distance adjustment of the two placement rods 9.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
