Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example:

[0022] like Figures 1-5 As shown, a high-strength wheel hub fatigue testing device includes a wheel hub fatigue testing device 1. A sound insulation mechanism is provided on the outer surface of the wheel hub fatigue testing device 1. The sound insulation mechanism includes a composite sound-absorbing wall 2 and a sound-absorbing door 3 to isolate noise. A sliding mechanism is provided at the top of the sound-absorbing door 3, including a pulley 5 for opening and closing the sound-absorbing door 3. A fixing mechanism is provided on the front surface of the sound-absorbing door 3, including a magnetic guide plate 7 and a magnetic guide block 12 for locking the sound-absorbing door 3 and the composite sound-absorbing wall 2. The composite sound-absorbing wall 2 is fixed to the outer surface of the wheel hub fatigue testing device 1. A track 4 is fixedly connected to the front surface of the composite sound-absorbing wall 2. The top of the pulley 5 is fitted onto the surface of the track 4, and a crossbar 8 is fixedly connected to the rear surface of the bottom end of the pulley 5. An opening is provided on the front surface of the sound-absorbing door 3. The sound-absorbing door 3 has a slot 9, with the rear end of the crossbar 8 inside the slot 9. A roller 6 is installed at the bottom of the sound-absorbing door 3. A C-shaped fixing rod 11 is fixedly connected to the front surface of the sound-absorbing door 3. A pull rod 10 is fitted on the surface of the C-shaped fixing rod 11. A magnetic block 12 is fixed inside the sound-absorbing door 3. A rotating block 13 is installed inside the front surface of the magnetic block 12. A triangular hole 14 is opened inside the rotating block 13. The two ends of the pull rod 10 are respectively located inside the triangular holes 14 on both sides. A strong magnet 15 is fixedly connected to the rear surface of the rotating block 13. A rubber ring 17 is installed inside the magnetic block 12. The rear end of the strong magnet 15 is located inside the rubber ring 17. An aluminum block 16 is fixedly connected to the middle of the magnetic block 12. A sealing groove 18 is opened in the middle of the composite sound-absorbing wall 2. A magnetic plate 7 is fixedly connected to the inner side of the sealing groove 18.

[0023] The existing wheel hub fatigue testing device 1 generates a lot of noise during long testing periods, which greatly affects the working environment and the production operations of the workers. By installing a sound insulation mechanism, when testing the wheel hub, the wheel is placed inside the wheel hub fatigue testing device 1 and fixed. Before starting, the sound-absorbing door 3 must be closed. The pull rod 10 is held and the sound-absorbing door 3 is pushed. The pulley 5 moves on the track 4, and the roller 6 moves on the ground track until the sound-absorbing door 3 reaches the sealing groove 18. Then, the pull rod 10 is lifted upwards, and the pull rod 10 slides upwards on the surface of the C-shaped fixing rod 11. The two ends of the pull rod 10 are respectively inserted into the triangular holes 14 on both sides. The rotating block 13 is pushed upwards, causing it to rotate 90 degrees. Simultaneously, the rotating block 13 rotates, causing the strong magnet 15 to rotate inside the rubber ring 17. After rotation, as... Figure 5 As shown, at this time, the N and S poles of the strong magnet 15 are respectively facing the two magnetic blocks 12. The N pole to the magnetic block 12, then to the other magnetic block 12 and then to the S pole forms a closed magnetic field line. At this time, the entire magnetic block 12 is magnetic. The magnetic block 12 and the magnetic plate 7 inside the sealing groove 18 attract each other. The slot 9 slides inside the crossbar 8. The rear end of the sound-absorbing door 3 enters the inner side of the sealing groove 18. The magnetic block 12 and the magnetic plate 7 are tightly attached and fixed. To open, simply press down the pull rod 10 to make the strong magnet... When body 15 rotates 90 degrees, the magnetic lines of force are interrupted by aluminum block 16. The magnetic lines of force can only form closed circuits in the two magnetic blocks 12 respectively. At this time, the entire magnetic block 12 is not magnetic, and the unlocking is completed. The sound-absorbing door 3 is pulled out from the inside of the sealing groove 18 and pushed to one side to complete the operation. By setting up a sound insulation mechanism, noise is isolated from the transmission to the outside. The cooperation between the sliding mechanism and the fixed mechanism improves the sealing performance, reduces sound leakage, greatly improves the comfort of the working environment, and the opening and closing operation is simple, improving work efficiency.

[0024] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, a heat exchanger 19 and a humidifier 20 are installed at the top of the composite sound-absorbing wall 2. By setting up the heat exchanger 19 and the humidifier 20, the temperature and humidity in the sealed space can be regulated, which facilitates the simulation of wheel hub fatigue testing under different humidity and temperature conditions.
