Figures 1-3 A drop test machine, comprising a bottom plate 1 and a stand 2 fixedly connected to the top outer wall of the bottom plate 1, a fixing rod 3 fixedly connected to the outer wall of the bottom plate 1 and the stand 2, a lifting block 5 slidingly connected to the outer wall of the fixing rod 3, a frame 6 fixedly connected to the outer wall of the lifting block 5, a bearing plate 8 rotatably connected to the outer wall of the frame 6 through a rotating shaft 7, and a lifting mechanism installed on the outer wall of the bottom plate 1 and the stand 2.

[0021] The side outer wall of the frame 6 is fixedly provided with a fixing frame 12, the fixing frame 12 is rotationally connected with a second screw rod 13, the outer wall of the second screw rod 13 is threadedly connected with a movable plate 15, the outer wall of the movable plate 15 is fixedly connected with a bolt 16, the side outer wall of the bearing plate 8 facing the fixing frame 12 is provided with a slot 11, and one end of the bolt 16 away from the movable plate 15 penetrates through the frame 6 and is adaptively inserted into the slot 11.

[0022] The lifting mechanism comprises a first screw rod 4 rotationally connected between the bottom plate 1 and the stand 2, a lifting block 5 threadedly connected to the outer wall of the first screw rod 4, a first motor 10 fixedly installed on the top outer wall of the stand 2, and an output shaft of the first motor 10 penetrating through the stand 2 and fixedly connected with the top end of the first screw rod 4.

[0023] The side outer wall of the fixing frame 12 away from the frame 6 is fixedly provided with a second motor 14, and the output shaft of the second motor 14 penetrates through the fixing frame 12 and is fixedly connected with one end of the second screw rod 13.

[0024] The bottom outer wall of the lifting block 5 is fixedly connected with a fixed plate 17, the outer wall close to the bottom end of the fixed plate 17 is provided with a suction disc 18, the rotating shaft 7 is downwardly rotated until the suction disc 18 is in contact with the suction disc 18, and the suction disc 18 can firmly suck the bearing plate 8.

[0025] The side outer wall of the frame 6 is fixedly connected with a limiting plate 9, the limiting plate 9 is located above the bearing plate 8 and is attached to the surface of the bearing plate 8, the limiting plate 9 can limit the upward rotation of the bearing plate 8, and when the limiting plate 9 is attached to the bearing plate 8, the slot 11 on the side of the bearing plate 8 away from the limiting plate 9 corresponds to the bolt 16.

[0026] The implementation principle of the falling test machine is as follows: in use, the first motor 10 is started, the output shaft of the first motor 10 drives the first screw rod 4 to rotate, the first screw rod 4 is threadedly rotated on the inner surface of the lifting block 5 to drive the lifting block 5 to move up and down along the outer wall of the first screw rod 4, the lifting block 5 slides on the outer wall of the fixed rod 3 when moving to limit and guide the lifting block 5 from being rotated by the first screw rod 4, the bearing plate 8 is lowered when the lifting block 5 is lowered, the user can place the product to be tested on the bearing plate 8, the product is lifted to the test height when the lifting block 5 is lifted by the lifting mechanism after the placement is completed.

[0027] Then the second motor 14 is started, the output shaft of the second motor 14 drives the second screw 13 to rotate, the second screw 13 is screwed in the movable plate 15, drives the movable plate 15 to move on the outer wall of the second screw 13, when the movable plate 15 moves away from the frame 6, drives the bolt 16 to disengage from the insertion slot 11, at the moment when the bolt 16 disengages from the insertion slot 11, the bearing plate 8 rotates downward around the rotating shaft 7 under the influence of the gravity of the product, the product falls from the bearing plate 8, and the test is completed;

[0028] When the bearing plate 8 rotates downward, the bearing plate 8 will contact the suction cup 18, the suction cup 18 can adsorb the bearing plate 8, prevents the bearing plate 8 from colliding and rebounding and contacting the falling product, ensures the stability of the test, after the test is completed, the bearing plate 8 can be manually rotated upward until the bearing plate 8 abuts against the limiting plate 9, at this time, the insertion slot 11 will be aligned with the bolt 16, and the movable plate 15 is driven to move close to the frame 6 by the second motor 14 and the second screw 13, and the bolt 16 is reinserted into the insertion slot 11 to fix the bearing plate 8.

[0029] It is worth noting that the length of the insertion slot 11 is equal to the length of the second screw 13, so the movement distance of the movable plate 15 and the bolt 16 can only make the bolt 16 disengage from the insertion slot 11, and the bolt 16 cannot disengage from the frame 6, so that the bolt 16 is always located in the frame 6, and the frame 6 can always limit the movable plate 15 through the bolt 16, and the movable plate 15 cannot be rotated by the rotation of the second screw 13.

[0030] Finally, it should be pointed out that: first, in the description of the application, it should be pointed out that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to represent the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
