[0023] The following is combined with Figure 1-4 The present invention is described in further detail.

[0024] Reference Figure 1 The automatic revolving door soundproof box includes a box body 1 and a door 2. The door 2 is hinged on the opening of the box body 1. The box body 1 is composed of a stainless steel layer, a cold-rolled plate layer, an aluminum plate layer, a damping sound insulation felt layer, a damping shock-absorbing pad layer, a high-density plate layer, a polyurethane sponge layer, a glass fiber wool layer and a sealing rubber from the outside to the inside. The structure of the door 2 is the same as that of the box body 1 and will not be repeated. The stainless steel layer has good corrosion resistance and can provide good protection for the internal structure. The damping sound insulation felt layer, the damping shock-absorbing pad layer, the high-density plate layer, the polyurethane sponge layer and the glass fiber wool layer all have good sound absorption and noise reduction effects, which can block the noise from propagating outside the box body 1 during the noise test, and can also block the external noise from propagating into the box body 1, avoiding noise pollution around the box body 1 while ensuring the accuracy of the noise test in the box body 1. After the door 2 is closed, the sealing rubber of the door 2 fits tightly with the sealing rubber of the box body 1, and the box body 1 is sealed to further block the propagation of noise.

[0025] Reference Figure 1 and Figure 2 A floating frame 6 is provided on one side where the box body 1 and the box door 2 are hinged. The floating frame 6 includes a first mounting plate 61 and a second mounting plate 62. The first mounting plate 61 is fixed on the outer wall of the box body 1, and the second mounting plate 62 is fixed on the outer wall of the box door 2. A plurality of mounting holes 7 are provided on the first mounting plate 61 and the second mounting plate 62. A switch assembly 3 is provided on the first mounting plate 61. The switch assembly 3 includes a transmission plate 32 and a push-pull cylinder 31. The transmission plate 32 is fixed on the second mounting plate 62. One end of the push-pull cylinder 31 is hinged on the first mounting plate 61. The piston rod of the push-pull cylinder 31 is hinged to the transmission plate 32.

[0026] In the initial state, the piston rod of the push-pull cylinder 31 is extended, and the box door 2 is in a closed state. When a noise test is required, the piston rod of the push-pull cylinder 31 is retracted, pulling the transmission plate 32 to move, and the transmission plate 32 drives the box door 2 to rotate, so that the box door 2 is opened, which is convenient for placing the acoustic and electrical products into the box body 1. After the acoustic and electrical products are placed in the box body 1, the piston rod of the push-pull cylinder 31 is extended, driving the box door 2 to close again, which is convenient for subsequent noise testing.

[0027] Since it is difficult to control the force of opening and closing the door 2 when the push-pull cylinder 31 is used, it is easy to cause excessive force on the door 2 during the closing process, causing the door 2 to impact the box body 1 and generate noise. Therefore, a buffer component 4 is provided on the top surface of the box body 1. When the door 2 is about to close, the closing of the door 2 is buffered. In this embodiment, when the angle between the door 2 and the box body 1 is 30°, the buffer component 4 buffers the closing of the door 2.

[0028] Reference Figure 1 and Figure 2 The buffer assembly 4 includes a mounting seat 41, a buffer 42 and a baffle 43. The mounting seat 41 is fixed on the top surface of the box body 1, the buffer 42 is fixed on the mounting seat 41, and the baffle 43 is fixed on the top surface of the box door 2. The baffle 43 rotates with the rotation of the box door 2, and the active end of the buffer 42 extends to the rotation path of the baffle 43. During the closing process of the box door 2, the baffle 43 rotates with the box door 2, gradually approaches the active end of the buffer 42, and finally abuts against the active end of the buffer 42. As the box door 2 is further closed, the baffle 43 pushes the detection end of the buffer 42 to retract, and the buffer 42 absorbs the impact force when the box door 2 is closed, which significantly reduces the sound when the box door 2 is closed. The buffer 42 can be a hydraulic buffer 42, an air buffer 42, etc.

[0029] Reference Figure 3 The box body 1 is provided with a locking assembly 5 on one side of the free end of the box door 2. The locking assembly 5 includes a buckle 51, an abutment plate 52 and a locking cylinder 53. The buckle 51 is fixed to the side wall of the free end of the box door 2. The buckle 51 rotates as the box door 2 is opened and closed. One end of the locking cylinder 53 is hinged to the outer wall of the box body 1, and the piston rod of the locking cylinder 53 is set toward the buckle 51. A fixing block is fixed on the outer wall of the box body 1, and the middle part of the abutment plate 52 is hinged to the fixing block. One end of the abutment plate 52 is connected to the piston rod of the locking cylinder 53. The extension and retraction of the piston rod of the locking cylinder 53 can drive the abutment plate 52 to swing.

[0030] After the door 2 is opened, or during the process of opening or closing the door 2, the piston rod of the locking cylinder 53 is in a retracted state, at which time the end of the abutment plate 52 away from the piston rod of the locking cylinder 53 swings away from the buckle 51 and escapes from the rotation path of the buckle 51, and the door 2 can be opened or closed smoothly. After the door 2 is closed, the piston rod of the locking cylinder 53 extends, driving the abutment plate 52 to swing, so that the end of the abutment plate 52 away from the piston rod of the locking cylinder 53 swings into the buckle 51, and after the abutment plate 52 enters the buckle 51, it applies a thrust to the inner wall of the buckle 51, so that the door 2 and the box body 1 fit more closely.

[0031] Reference Figure 1 and Figure 4 A first protective cover 8 is fixed on the outer wall of one side where the box body 1 and the box door 2 are hinged, and the push-pull cylinder 31 is inside the first protective cover 8. A second protective cover 9 is fixed on the outer wall of the box body 1 on one side of the free end of the box door 2, and the locking cylinder 53 is inside the second protective cover 9. Since the push-pull cylinder 31 and the locking cylinder 53 swing during operation, there is a certain impact on objects or staff in the surrounding area. The first protective cover 8 protects the push-pull cylinder 31, and the second protective cover 9 protects the locking cylinder 53 to prevent the push-pull cylinder 31 and the locking cylinder 53 from hitting surrounding objects and being damaged during operation; at the same time, the first protective cover 8 and the second protective cover 9 protect the surrounding staff to prevent the push-pull cylinder 31 and the locking cylinder 53 from affecting the surrounding staff during operation.

[0032] The working process of the embodiment of the present invention is as follows: in the initial state, the box door 2 is closed, the piston rod of the push-pull cylinder 31 extends, the piston rod of the locking cylinder 53 extends, the abutment plate 52 extends into the buckle 51, and applies a thrust to the buckle 51, so that the box door 2 is tightly attached to the box body 1. When the acoustic and electrical product needs to be tested for noise, the piston rod of the locking cylinder 53 retracts, the abutment plate 52 escapes from the buckle 51, the piston rod of the push-pull cylinder 31 retracts, and the box door 2 is pulled open. After the acoustic and electrical product is placed in the box body 1, the piston rod of the push-pull cylinder 31 extends, pushing the box door 2 to close. When the box door 2 is closed to the angle between the box door 2 and the box body 1 is 30°, the box door 2 abuts against the buffer 42, and the buffer 42 buffers the closing of the box door 2 until the box door 2 is completely closed. The piston rod of the locking cylinder 53 extends, the abutment plate 52 re-extends into the buckle 51 and applies a thrust to the buckle 51, locking the box door 2. After completing the noise test, when replacing the acoustic and electrical products, just repeat the above-mentioned process of opening and closing the box door 2.

[0033] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
