Detailed Implementation

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution:

[0026] A portable product drop tester includes a fixed frame 1. An adjusting screw 2 is rotatably connected inside the fixed frame 1. A Z-shaped movable plate 3 is slidably connected to the inner side of the fixed frame 1. The adjusting screw 2 passes through the Z-shaped movable plate 3 and is threadedly connected to it. An electric telescopic rod 4 is fixedly connected above the Z-shaped movable plate 3. A push block 5 is fixedly connected below the electric telescopic rod 4. Two clamping arms 6 are rotatably connected to one side of the Z-shaped movable plate 3. A spring 7 is fixedly connected between the two clamping arms 6. A folding mechanism is provided below the fixed frame 1. A servo motor 8 is fixedly connected above the fixed frame 1. The output end of the servo motor 8 is coaxially fixedly connected to the adjusting screw 2. First, the tester places the test product between the two clamping arms 6. Then, the electric telescopic rod 4 is activated, which drives the push block 5 to move downward. The push block 5 moves downward between the two clamping arms 6, so that the bottom ends of the two clamping arms 6 come closer to each other, clamping the test product. During this process, the spring 7 is compressed and contracted by the two clamping arms 6. Then the tester starts the servo motor 8, which drives the adjusting screw 2, which is fixedly connected to its output end, to rotate. At this time, the Z-shaped movable plate 3 moves along the direction of the adjusting screw 2 until it reaches the specified height. Then the electric lifting rod 4 is started, which drives the push block 5 to move upward. At this time, the spring 7 opens, causing the bottom ends of the two clamping arms 6 to move away from each other, and the test item falls between the two clamping arms 6.

[0027] A connecting shaft 9 is fixedly connected to both sides of the fixed frame 1. Mounting holes 10 are opened on both sides of the fixed frame 1, and the mounting holes 10 are located below the connecting shaft 9. The folding mechanism includes two brackets 11. A connecting hole 12 is opened on the inner side of each of the two brackets 11. The connecting shaft 9 is rotatably connected to the connecting hole 12. A fixing hole 13 and a fixing hole 14 are opened on each of the two brackets 11. A fixing bolt 15 is provided on both sides of the fixed frame 1. The fixing bolt 15 is threadedly connected to the mounting hole 10. The fixing hole 13 and the fixing hole 14 are both adapted to the fixing bolt 15. When this utility model needs to be folded and stored, first unscrew the two fixing bolts 15 and take them out from the fixing hole 13. Then, rotate the fixed frame 1 downward 180° with the connecting shaft 9 as the axis. Then insert the fixing bolt 15 from the fixing hole 14 and screw it into the mounting hole 10.

[0028] A handle 16 is fixedly connected to the top of the fixed frame 1, and a base 17 is fixedly connected to the bottom of the two supports 11. A scale line 18 is provided on one side of the fixed frame 1. The handle 16 makes it convenient for operators to carry and transport the product. The base 17 serves as a counterweight and fixation. The scale line 18 is used to assist testers in adjusting the height of the product.

[0029] The working principle of this utility model is as follows:

[0030] First, the tester places the test product between the two clamping arms 6. Then, the electric telescopic rod 4 is activated, causing the push block 5 to move downwards. The push block 5 moves downwards between the two clamping arms 6, bringing the bottom ends of the two clamping arms 6 closer together and clamping the test product. During this process, the spring 7 is compressed and contracted by the two clamping arms 6. Next, the tester activates the servo motor 8, which drives the adjusting screw 2, which is fixedly connected to its output end, to rotate. At this time, the Z-shaped movable plate 3 moves along the direction of the adjusting screw 2 until it reaches the specified height. Then, the electric telescopic rod 4 is activated, causing the push block 5 to move upwards. At this time, the spring 7 opens, causing the bottom ends of the two clamping arms 6 to move away from each other, and the test item falls between the two clamping arms 6. With the help of the scale lines 18 on the fixed frame 1, the height of the test product can be quickly and accurately adjusted to adapt to different testing needs. When this utility model needs to be folded and stored, first unscrew the two fixing bolts 15 and take them out from the fixing hole 13. Then, rotate the fixing frame 1 downwards by 180° with the connecting shaft 9 as the axis. Then, insert the fixing bolts 15 from the fixing hole 14 and screw them into the mounting hole 10. The folding is completed. The height after folding is only half of the working state, which makes it convenient to store, carry and transport. The folding process is also very quick.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
