[0037] Please refer to Figures 1 to 7, A carton drop test device that is convenient to adjust, including a base 1, a mounting frame 2 fixedly installed on the base 1, and a control box 3 arranged on the base 1. A movable sleeve 4 is movably installed on the mounting frame 2, and the movable sleeve 4 is driven by a driving mechanism to move up and down along the mounting frame 2. The driving mechanism includes a driving motor 9a, a speed reducer 9b is provided on the driving motor 9a, a driving gear 9c is provided at the output end of the speed reducer 9a, and the driving gear 9c meshes with a rack 2a provided on the mounting frame 2. A support member 5 for placing the carton 100 is rotatably installed at the lower end of the movable sleeve 4, and the support member 5 is connected by a push-pull cylinder 6 provided on one side. An adjustable limit assembly 7 is installed at the upper end of the movable sleeve 4.

[0038] The specific structure is as follows:

[0039] The limit assembly 7 includes a vertical rod 7a fixed to the movable sleeve 4. A horizontal rod 7b is movably arranged on the vertical rod 7a, and a carton corner fixing block 7c is provided on the horizontal rod 7b to fix the inclined carton 100. A side limit rod 7d is provided on one side of the vertical rod 7a on one side of the carton 100, and a front limit rod 7e is provided at the front end of the horizontal rod 7b to limit the front side of the carton 100.

[0040] In this embodiment, the connection between the horizontal rod 7a and the vertical rod 7b, the connection between the side limit rod 7d and the vertical rod 7a, and the connection between the front limit rod 7e and the horizontal rod 7a are all connected by a movable joint 7f, and a fixing knob 7g is provided on the movable joint 7f for fixing; the connection between the carton corner fixing block 7c and the horizontal rod 7b is also fixed by the fixing knob 7g. At the same time, both the vertical rod 7a and the horizontal rod 7b are provided in two groups.

[0041] The limit assembly 7 in the present utility model can limit the side by the side limit rod 7d. The upper carton corner fixing block 7c is provided with a clamping groove corresponding to the right angle of the carton, and is clamped and fixed at the right angle position of the carton 100. At the same time, it is limited by the front limit rod 7e at the front side, and is supported by the support member 5 below. Furthermore, the carton 100 at different inclination angles can be fixed. At the same time, it is convenient to adjust the positions of the carton corner fixing block 7c, the side limit rod 7d and the front limit rod 7e, which is convenient for fixing cartons at different inclination angles and improves the convenience of carton drop testing.

[0042] Please refer to Figure 2, a first mounting seat 5a is provided at the lower end of the movable sleeve 4. One end of the support member 5 is rotatably mounted on the first mounting seat 5a through a rotating shaft 5b. The other end of the support member 5 is provided with a support plate 5c, and an arc-shaped limiting portion 5d is provided on the support plate 5c to limit the bottom of the placed carton 100. When the carton is inclined for testing the drop of the right-angle part, it is easy for the bottom of the carton to move on the support plate 5c. Therefore, the limiting portion 5d can play a role of resisting and blocking, and at the same time, the arc-shaped design facilitates the movement of the support member 5 relative to the carton 100.

[0043] Further, the upper end of the rotating shaft 5b protrudes out of the first mounting seat 5a and is provided with a limiting wheel 5e, and a limiting tooth 5f is provided on the limiting wheel 5e. A limiting cylinder 8 is also provided on the first mounting seat 5a, and a limiting shaft 8a connected to the limiting cylinder 8 can cooperate with the limiting tooth 5f to fix the rotating shaft 5b.

[0044] Specifically, a second mounting seat 6a is provided on the movable sleeve 4. The push-pull cylinder 6 is rotatably mounted on the second mounting seat 6a, and the output rod 6b of the push-pull cylinder 6 is rotatably connected to the support member 5.

[0045] In the present utility model, the control box 3 adopts a PLC control system to control the driving motor 9a to drive the movable sleeve 4 to move up and down, and at the same time control the push-pull cylinder 6 and the limiting cylinder 8 to work, thereby realizing automatic control testing. This control method belongs to the prior art, so it will not be described in detail.

[0046] The working principle of the present utility model is as follows:

[0047] When it is necessary to perform a drop test on the carton 100 at a specified height, first, adjust the height of the movable sleeve 4 to the specified height of the test. Then, according to the position of the test carton, adjust the positions of the carton top angle fixing block 7c and the front side limiting rod 7e, and adjust them roughly according to the angle of the carton. Since the test angle of the carton does not need to be particularly precise, it only needs to be set according to the position of the test drop. After the position adjustment of the limiting component 7 is completed, the carton is installed on the support plate 5c. At this time, the limiting shaft 8a connected to the limiting cylinder 8 meshes with the limiting tooth 5c to maintain the stability of the support member 5. The upper end of the carton is fixedly clamped with the carton top angle fixing block 7c. After the carton is fixed, the next drop test can be carried out.

[0048] The limiting shaft 8a connected to the limiting cylinder 8 disengages from the limiting tooth 5c, and at the same time, the push-pull cylinder 6 pulls the limiting member 5 backward to rotate. At this time, the limiting member 5 disengages from the carton, and the carton automatically drops downward, and the damage condition of the dropped carton is observed. The structure of the present utility model can perform drop tests on cartons at different heights, test cartons at different angles or with materials, and is limited by the limiting component 7, improving the stability during the test.

[0049] Based on the disclosure and teachings of the above specification, those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model. Any other devices using the same or similar ones are within the protection scope of the present utility model.
