[0024] The soundproof cover 2 is made of transparent acrylic material, the arc rails 3 on both sides are arranged in a quarter arc, and the sliding sleeve 5 slides and rotates along the outer wall of the arc rail 3 as a motion trajectory.

[0025] Better: In the untested state, the connecting plate 6 and the abutment plate 8 are both in a vertical upright state inside the soundproof cover 2. During the test, the electric telescopic rod 4 is operated to drive the connecting plate 6 to slide along the outer walls of the arc-shaped rails 3 on both sides with the cooperation of the sliding sleeves 5 on both sides, and adjust it from a vertical state to a horizontal state. With the help of squeezing the vertical rods 7 on both sides to deform the first spring 9, the abutment plate 8 is brought into contact with the home appliance to be tested below. In this process, it can be ensured that the knocking force during the contact between the abutment plate 8 and the outer wall of the home appliance can be balanced and uniform, thereby ensuring the accuracy and reliability of the test results.

[0026] A noise sensor 10 is fixedly connected to the bottom of the inner wall of the detection base 1, and columns 11 are fixedly connected at the four corners of the top of the inner wall of the detection base 1. The tops of the four side columns 11 are fixedly connected to the second springs 12, and the adjacent ends of the four side second springs 12 are fixedly connected to the detection base 13. Grooves 14 are provided on both sides of the top of the detection base 13, and the inner walls of the grooves 14 on both sides are slidably connected with positioning plates 15. The outer walls of the positioning plates 15 on both sides are fixedly connected with third springs 16. A motor 17 is fixedly connected to the center position of the bottom of the detection base 13, and a dial 18 is fixedly connected to the driving end of the motor 17. The dial 18 is rotatably connected to the top of the detection base 13. The bottom of the detection base 13 is located next to the motor 17 and is fixedly connected to a vibration pickup 19. A control panel 20 is fixedly installed on the front outer wall of the sound insulation cover 2, and the control panel 20 is electrically connected to the electric telescopic rod 4, the noise sensor 10 and the vibration pickup 19.

[0027] The elastic stiffness of the second spring 12 matches that of the detection seat 13 , and the positioning plate 15 is arranged at a right angle.

[0028] Better: After placing the home appliance to be tested on the detection seat 13, rotate to close the sound insulation cover 2, and control the motor 17 to start operating through the control panel 20. According to the size of the home appliance to be tested, the motor 17 drives the dial 18 to rotate on the top of the detection seat 13. The outer wall of the dial 18 squeezes the positioning plates 15 on both sides to move and adjust along the inner wall of the groove 14, and finally adheres to the outer wall of the home appliance to tightly position it. The setting of the third springs 16 on both sides can firmly lock the positioning plates 15 on both sides. After processing, as the abutment plate 8 knocks on the outer wall of the home appliance for testing, the noise sensor 10 and the vibration pickup 19 can extract the corresponding information in the detection environment and transmit it to the control panel 20 for detection and analysis.

[0029] The above implementation works as follows:

[0030] The steps for running the job are as follows:

[0031] First, place the home appliance to be tested on the detection seat 13, rotate and close the sound insulation cover 2 to cover the outside of the detection base 1 to form a closed environment, and control the motor 17 to start operation through the control panel 20. According to the size of the home appliance to be tested, the motor 17 drives the dial 18 to rotate on the top of the detection seat 13. The outer wall of the dial 18 squeezes the positioning plates 15 on both sides to move and adjust along the inner wall of the groove 14, and finally adheres to the outer wall of the home appliance to tightly position it. The setting of the third springs 16 on both sides can firmly lock the positioning plates 15 on both sides.

[0032] After the processing is completed, as the abutment plate 8 performs a knocking test on the outer wall of the home appliance, the noise sensor 10 and the vibration pickup 19 can extract the corresponding information in the detection environment and transmit it to the control panel 20 for detection and analysis. In the undetected state, the connecting plate 6 and the abutment plate 8 are both in a vertical upright state inside the soundproof cover 2. During the detection, the electric telescopic rod 4 is operated to drive the connecting plate 6 to slide along the outer wall of the arc-shaped rails 3 on both sides with the cooperation of the sliding sleeves 5 on both sides, and adjust it from a vertical state to a horizontal state. With the help of squeezing the vertical rods 7 on both sides to deform the first spring 9, the abutment plate 8 is made to contact the home appliance to be detected below. In this process, it can be ensured that the knocking force during the contact between the abutment plate 8 and the outer wall of the home appliance can be balanced and uniform, thereby ensuring the accuracy and reliability of the detection results.
