Two sliding rods are connected to the opposite side of the first fixing block and the second fixing block, and a second adjusting block is slidably connected to the outer wall of the sliding rod. A fourth connecting rod is rotatably connected to both sides of the bottom end of the second adjusting block, and a sliding column is connected to the end of each fourth connecting rod away from the second adjusting block. A fifth connecting rod is rotatably connected to the outer wall of each sliding column, and a first adjusting block is rotatably connected to one end of each of the two fifth connecting rods. A telescopic rod is connected to one side of the outer wall of the second adjusting block.

[0007] Furthermore, clamps are installed at the bottom of both the second and first adjusting blocks, and anti-slip pads are provided on the inner walls of the clamps.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 This utility model provides a technical solution for a load-bearing testing device for an infant jumping trainer:

[0022] In the embodiments of this utility model, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The system includes a frame 1 and a training device 21. A pressure assembly is installed inside the frame 1. The pressure assembly includes a first motor 2 installed inside the frame 1. One end of the first motor 2 is rotatably connected to a first crank 3. The bottom inner wall of the first crank 3 is rotatably connected to a first connecting rod 4. One end of the first connecting rod 4 is rotatably connected to a second connecting rod 5. The end of the second connecting rod 5 away from the first connecting rod 4 is rotatably connected to a mounting block 6. The bottom end of the mounting block 6 is fixedly connected to a push rod 7. The other end of the first connecting rod 4 is connected to a third connecting rod 8. The end of the third connecting rod 8 away from the first connecting rod 4 is connected to a second crank 9. One end of the second crank 9 is rotatably connected to a second motor 10.

[0023] It should be noted that after the first motor 2 starts, it drives the first connecting rod 4 by rotating the first crank 3. The movement of the first connecting rod 4 causes the second connecting rod 5 and the third connecting rod 8 to be linked, thereby pushing the push rod 7 to reciprocate. The reciprocating motion of the push rod 7 simulates the jumping action of an infant on a jumping training device, applying different pressures and frequencies to the training device to test its load-bearing capacity and stability. At the same time, the start of the second motor 10 can cause the second crank 9 to rotate. When the second crank 9 rotates, it will drive the third connecting rod 8, which is connected to the rotation of the second crank 9, to pull the first connecting rod 4. At the same time, it will link the second connecting rod 5 to change the distance the push rod 7 is pushed out. This allows for necessary adjustments when different pressures need to be applied or when the size of the device needs to be changed.

[0024] See Figure 4 , Figure 5 The bottom end of the push rod 7 is connected to the mounting plate 11. The bottom ends of the mounting plate 11 are connected to the first fixing block 12 and the second fixing block 13 respectively. The opposite sides of the first fixing block 12 and the second fixing block 13 are connected to two sliding rods 14. The outer walls of the sliding rods 14 are slidably connected to the second adjusting blocks 16. The bottom ends of the second adjusting blocks 16 are rotatably connected to the fourth connecting rods 18. The end of each fourth connecting rod 18 away from the second adjusting block 16 is connected to the sliding column 19. The outer wall of each sliding column 19 is rotatably connected to the fifth connecting rod 20. The two fifth connecting rods 20 are rotatably connected to the first adjusting block 15. The outer wall of one side of the second adjusting block 16 is connected to the telescopic rod 17.

[0025] It should be noted that: the bottom of the mounting plate 11 is connected to the first fixing block 12 and the second fixing block 13 respectively. The opposite side of the first fixing block 12 and the second fixing block 13 is connected to two sliding rods 14. The outer wall of the sliding rod 14 is slidably connected to the second adjusting block 16. The bottom of the second adjusting block 16 is rotatably connected to the fourth connecting rod 18. The first adjusting block 15 is linked through the fourth connecting rod 18, the sliding column 19, and the fifth connecting rod 20. When the telescopic rod 17 starts to push or pull the second adjusting block 16, it will simultaneously drive the first adjusting block 15 to move relative to each other. This can train the equipment 21 to test different pressure points or adapt to equipment of different sizes.

[0026] See Figure 1 , Figure 4 The bottom ends of the second adjusting block 16 and the first adjusting block 15 are each equipped with a clamp. The inner wall of the clamp is provided with an anti-slip pad. The anti-slip pad is made of wear-resistant material. The bottom ends of the second adjusting block 16 and the first adjusting block 15 are equipped with training equipment 21.

[0027] It should be noted that the clamp can fix the training equipment 21 and prevent instability caused by movement or vibration of the equipment during the test. At the same time, the anti-slip pad increases the friction between the clamp and the training equipment 21, improves the stability of the overall structure, and protects the paint surface of the training equipment 21 from being damaged by the clamp.

[0028] See Figure 5 The first fixing block 12 and the second fixing block 13 are fixedly connected to the bottom of the mounting plate 11. The inner walls of the second adjusting block 16 and the first adjusting block 15 are slidably connected to the outer wall of the slide rod 14. The tops of the two sliding columns 19 are slidably connected to the inner wall of the mounting plate 11.

[0029] It should be noted that the fixed connection between the first fixing block 12, the second fixing block 13 and the mounting plate 11 ensures the stability of the sliding of the second adjusting block 16 and the first adjusting block 15 during the test, preventing inaccurate data due to shaking or vibration of the equipment during the test, and ensuring the reliability of the test results.

[0030] See Figure 2 The outer wall of the first motor 2 is fixedly connected to the inner wall of the frame 1, the end of the first crank 3 away from the first motor 2 is rotatably connected to the inner wall of the frame 1, and the bottom end of the push rod 7 is fixedly connected to the top end of the mounting plate 11.

[0031] It should be noted that the fixed connection between the push rod 7 and the mounting plate 11 ensures the effective transmission of force and the accuracy of the test.

[0032] See Figure 1 The bottom ends of both sides of the mounting plate 11 are slidably connected to the inner wall of the mounting plate 11, and the top end of the mounting plate 11 is slidably connected to the inner top wall of the frame 1.

[0033] It should be noted that the sliding connection allows the mounting plate 11 to be adjusted for different device sizes, improving the versatility of the components.

[0034] Working principle: The first motor 2 drives the first crank 3 to rotate on the inner wall of the frame 1. When the first crank 3 rotates, it drives the first connecting rod 4 to swing. The swing of the first connecting rod 4 pushes the second connecting rod 5, which is rotatably connected to the first connecting rod 4. Because the push rod 7 is rotatably connected to the second connecting rod 5 through the mounting block 6, the swing can be converted into a vertical reciprocating motion. The bottom end of the push rod 7 is fixedly connected to the top end of the mounting plate 11. Therefore, when the first motor 2 is started, it can drive the mounting plate 11 to perform up-and-down reciprocating pressure testing. At the same time, if the second motor 10 is started, the second motor 10 will cause the second crank 9 to deflect. The rotation of the second crank 9 on the inner wall of the third connecting rod 8 can change the position of the third connecting rod 8. Since the second crank 9 is rotatably connected to the inner wall of the frame 1, the position of the second crank 9 will not change. However, the change in the angle of the first connecting rod 4 can change the distance that the push rod 7 pushes out of the mounting plate 11.
