[0019] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0020] Embodiment 1: refer to Figures 1-4A power cord tensile testing machine includes a support frame 1, a movable frame 3 slidably connected to one side of the upper end of the support frame 1, a drive motor 4 for moving the movable frame 3 connected to the support frame 1, a clamp 2 fixedly connected to the other side of the upper end of the support frame 1, a tensile gauge 5 hanging on the movable frame 3, the movable frame 3 and the clamp 2 being on the same straight line, and the tensile gauge 5 being located between the movable frame 3 and the clamp 2, a shock absorber 6 slidably inserted into the movable frame 3, one side of the shock absorber 6 being an arc-shaped structure, a plurality of airbags 8 being connected to the arc-shaped structure of the shock absorber 6, and a spring 7 fixedly connected to the shock absorber 6, one end of the spring 7 being fixedly connected to the movable frame 3.
[0021] Work process:
[0022] When performing a tensile test on the power cord, one end of the power cord is fixed to the tensile gauge 5, and the other end of the power cord is fixed to the clamp 2. After the drive motor 4 is started, it drives the movable frame 3 to move away from the clamp 2. After the movable frame 3 moves, it pulls the power cord through the tensile gauge 5. After the movable frame 3 moves a certain distance, the power cord is in a straight state. The tensile gauge 5 displays the tensile force on the power cord. When the tensile force on the tensile gauge 5 reaches the set value, the drive motor 4 stops driving the movable frame 3 to move, and the tensile gauge 5 continues to pull the power cord to perform the tensile test.
[0023] After the power cord breaks, the tension value on the tension gauge 5 drops to zero. At the same time, the tension gauge 5 impacts the shock absorber 6. The airbag 8 is located on the shock absorber 6. The airbag 8 reduces the impact intensity between the tension gauge 5 and the shock absorber 6. After the shock absorber 6 is impacted, it pulls the spring 7. The spring 7 generates elastic force after being pulled. The elastic force generated by the spring 7 buffers the shock absorber 6. With the cooperation of the airbag 8, the impact intensity on the tension gauge 5 is reduced, making the tension gauge 5 less likely to be damaged by the collision.
[0024] Example 2: In Example 1, after the power cord breaks, the broken power cord bounces to both sides, and the bounced power cord hits the device, which can easily cause damage to the device. (Refer to...) Figure 3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the upper end of the movable frame 3 is provided with a slot, a card block 9 is engaged in the slot, the upper end of the card block 9 is fixedly connected to a first connecting rod 10, one end of the first connecting rod 10 is fixedly connected to an anti-ballistic mechanism, and the anti-ballistic mechanism is located between the clamp 2 and the tension gauge 5.
[0025] The locking block 9 fixes the first connecting rod 10, and the first connecting rod 10 fixes the anti-ballistic mechanism. The two ends of the power cord are respectively fixed on the clamp 2 and the tension gauge 5. The power cord between the clamp 2 and the tension gauge 5 is located inside the anti-ballistic mechanism. The anti-ballistic mechanism is in contact with the power cord. After the power cord breaks, the anti-ballistic mechanism limits the power cord. At the same time, the friction between the anti-ballistic mechanism and the power cord slows down the broken power cord, so that the power cord is not easily ejected, and thus it is not easy to damage the device.
[0026] Example 3: In Example 2, after the movable frame 3 moves, the distance between it and the clamp 2 changes, but the shielding distance of the anti-ballistic missile mechanism cannot be changed. (Refer to...) Figures 2-3 As another preferred embodiment of this utility model, the difference from embodiment 2 is that the anti-ballistic mechanism includes a first open mask 11, one end of the first open mask 11 is fixedly connected to a first connecting rod 10, the other end of the first open mask 11 is provided with a movable groove, a second open mask 12 is slidably connected to the movable groove, the upper end of the second open mask 12 is fixedly connected to a second connecting rod 13, one end of the second connecting rod 13 is fixedly connected to a fixed seat 14, the fixed seat 14 is snapped into the support frame 1, and an anti-slip pad is fixedly connected to the fixed seat 14. The anti-slip pad is an anti-slip rubber pad and is located between the fixed seat 14 and the support frame 1.
[0027] The fixed base 14 fixes the second connecting rod 13, and the second connecting rod 13 fixes the second open mask 12. After the movable frame 3 moves, it drives the locking block 9 to move. The locking block 9 drives the first connecting rod 10 to move. The first connecting rod 10 drives the first open mask 11 to move. After the first open mask 11 moves, the distance between it and the second open mask 12 increases. The first open mask 11 unfolds, and the covering distance can be adjusted.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
