[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0041] For ease of description, the front, back, left, and right directions of this application are as follows: Figure 1 shown.

[0042] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure provides a drop test device, which includes a clamping plate 10, a rangefinder 20 and a rotating rod 30. The clamping plate 10 is used to clamp the device to be tested 60; the rangefinder 20 is movably arranged on the clamping plate 10; one end of the rotating rod 30 is rotatably connected to the clamping plate 10, and the other end of the rotating rod 30 is rotatably connected to the rangefinder 20 to adjust the height of the rangefinder 20; wherein, as shown in FIG. Figures 1 to 3 As shown, the rotating rod 30 can drive the rangefinder 20 to move between a first position and a second position. When the rangefinder 20 is in the first position, the rangefinder 20 is located below the clamp 10, and the rangefinder 20 is flush with the component to be tested of the device to be tested 60; when the rangefinder 20 is in the second position, the rangefinder 20 is flush with the lower end of the clamp 10.

[0043] In the disclosed embodiment, the clamping plate 10 is used to clamp the device to be tested 60, and the device to be tested 60 is an item such as a refrigerator, a freezer or a freezer that needs to be dropped or clamped. The rangefinder 20 is rotatably arranged on the clamping plate 10 through the rotating rod 30. The rangefinder 20 can rotate relative to the clamping plate 10 and can also adjust the height relative to the clamping plate 10, so that the rangefinder 20 can rotate and can also be raised and lowered. In this way, when a drop test is required, the rangefinder 20 is adjusted to move to the first position so that the rangefinder 20 is flush with the part to be tested of the device to be tested 60, so that the drop height of the device to be tested 60 can be accurately measured. For example, when a corrugation test is required, the part to be tested is a corrugation, and the rangefinder 20 is flush with the corrugation 601 of the device to be tested at the lowest end of the device to be tested 60. When a surface test is required, the part to be tested is a surface, and the rangefinder 20 is flush with the surface at the lowest end of the device to be tested. In this way, there is no need to manually use a tape measure to check the drop height, nor is there a need to measure repeatedly, which improves the accuracy of height measurement and also improves the accuracy of measurement.

[0044] In addition, when a clamping test is required, the rangefinder 20 is flush with the lower end of the clamping plate 10, so that the height of the clamping plate 10 can be tested to ensure that the height of the device to be tested 60 meets the set height during the clamping test.

[0045] The other end of the rotating rod 30 is rotatably connected to the rangefinder 20, so that the extending direction of the rangefinder 20 is always perpendicular to the ground, avoiding the rangefinder 20 from tilting, so that the rangefinder 20 can accurately and stably test the height, thereby improving the accuracy of the test.

[0046] Optionally, when the rangefinder 20 is in the first position, the lower end of the rangefinder 20 is flush with the lower end of the component to be tested of the test device 60; when the rangefinder 20 is in the second position, the lower end of the rangefinder 20 is flush with the lower end of the clamp 10.

[0047] In the disclosed embodiment, the lower end of the rangefinder 20 is the endpoint of the rangefinder 20 for measuring distance, which facilitates the adjustment of the position of the rangefinder 20 so as to align the rangefinder 20 with the clamp 10 or the device to be tested 60 .

[0048] It can be understood that when the distance meter 20 is in other measurement modes, it is necessary to adjust the distance measurement end point of the distance meter 20 to be flush with the lowermost end of the device to be tested 60 or the lower end of the clamping plate 10 .

[0049] Alternatively, if Figure 7 and Figure 8As shown, the drop test device also includes a rotating button 406, which is movably arranged at one end of the rotating rod 30; wherein the rotating button 406 can move between a locking position and an unlocking position. When the rotating button 406 is in the locking position, the rotating button 406 abuts against the rotating rod 30, and the rotating button 406 restricts the rotation of the rotating rod 30; when the rotating button 406 is in the unlocking position, the rotating button 406 is separated from the rotating rod 30, and the rotating rod 30 can rotate.

[0050] In the disclosed embodiment, the rotating knob 406 is movably disposed at one end of the rotating rod 30. Since one end of the rotating rod 30 is rotatably connected to the clamp 10, the rotating knob 406 is used to lock or unlock the rotating rod 30. When the rotating knob 406 locks the rotating rod 30, the rotating knob 406 can abut against the rotating rod 30 to limit the rotation of one end of the rotating rod 30. In this way, the height of the rangefinder 20 can be fixed, thereby ensuring the consistency of the height of the rangefinder 20 during the drop test or the clamping test, and ensuring the accuracy of the test results.

[0051] Optionally, a first rotating hole 301 is provided at one end of the rotating rod 30, and the drop test device also includes a first rotating column 40, one end of which is connected to the splint 10 and extends from the splint 10 in a direction away from the splint 10, and the first rotating column 40 is rotatably connected to the first rotating hole 301.

[0052] In the disclosed embodiment, the first rotating column 40 extends from the splint 10 in a direction away from the splint 10, so that the rotating rod 30 rotatably connected to the first rotating column 40 can be spaced apart from the splint 10, providing sufficient space for the rotation of the rotating rod 30 to ensure smooth rotation of the rotating rod 30.

[0053] Optionally, the first rotating hole 301 passes through the rotating rod 30, the first rotating column 40 passes through the first rotating hole 301, and the other end of the first rotating column 40 extends to the side of the rotating rod 30 away from the splint 10; the rotating button 406 is located on the side of the rotating rod 30 away from the splint 10, and the rotating button 406 is provided with a second rotating hole 302, and the other end of the first rotating column 40 is rotated and located in the second rotating hole 302, and the rotating button 406 can move between a locked position and an unlocked position along the extension direction of the first rotating column 40.

[0054] In the embodiment of the present disclosure, the first rotating hole 301 passes through one end of the rotating rod 30 along the thickness direction of the rotating rod 30, so that after the first rotating column 40 is rotatably connected to the rotating hole, it can also pass through the first rotating hole 301 to extend to the side of the rotating rod 30 away from the splint 10, and the rotating button 406 is rotatably connected to the other end of the first rotating column 40 that extends to the side of the rotating rod 30 away from the splint 10, and the rotating button 406 can rotate relative to the rotating rod 30, and can move along the first rotating column 40 in the direction close to the rotating rod 30 and away from the rotating rod 30 through rotation, so that when the first rotating column 40 moves to abut against the side wall of the rotating rod 30 away from the splint 10, the rotating button 406 can lock the rotating rod 30, limit the rotating rod 30 from rotating around the first rotating column 40, and thereby limit the rotating rod 30 from rotating relative to the splint 10. When the rotating knob 406 moves in a direction away from the rotating rod 30, the rotating knob 406 is separated from the rotating rod 30, so that the rotating knob 406 no longer limits the rotating rod 30, and the rotating rod 30 can rotate around the first rotating column 40, so that the rangefinder 20 can be driven to rotate by the rotating rod 30 to adjust the relative position of the rangefinder 20 and the clamping plate 10.

[0055] Optionally, the outer wall surface of the rotating knob is provided with a plurality of raised edges to facilitate the user to rotate the rotating knob 406 .

The second rotating column 501 is rotatably connected to the fixing member 50 on which the rangefinder 20 is installed, so that when one end of the rotating column rotates, the other end of the rotating rod 30 can rotate relative to the second rotating column 501, so that the fixing member 50 rotatably connected to the second rotating column 501 can maintain the extension direction unchanged, and also enable the rangefinder 20 installed on the fixing member 50 to maintain a direction perpendicular to the ground, thereby ensuring the test accuracy and stability of the rangefinder 20.
