[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figure 1-3 A detachable double-layer decorative panel comprises an inner panel 1 and an outer panel 2, both of which are rectangular, and a sound-absorbing cotton 3 arranged therebetween, wherein a connecting piece 4 is protruding outward from the middle of one side of the inner panel 1 close to the sound-absorbing cotton 3, and a fastener 5 cooperating with the connecting piece 4 is arranged on the outer panel 2. After the connecting piece 4 passes through the sound-absorbing cotton 3, it cooperates with the fastener 5 to fix the inner panel 1 and the outer panel 2 together; a telescopic positioning piece 6 for adjusting the distance between the inner panel 1 and the outer panel 2 is arranged between the inner panel 1 and the outer panel 2, and the two ends of the telescopic positioning piece 6 are fixedly connected to the inner panel 1 and the outer panel 2 respectively; the sound-absorbing cotton 3 is sleeved on the outer periphery of the telescopic positioning piece 6.

[0025] Furthermore, the connecting piece 4 is an internally threaded sleeve, and the sound-absorbing cotton 3 is sleeved on the outer periphery of the internally threaded sleeve; the fastener 5 is a countersunk bolt, and the external thread of the countersunk bolt matches the internally threaded sleeve; a threaded through hole 21 is provided in the middle of the outer plate 2, and the countersunk bolt is locked with the internally threaded sleeve after passing through the threaded through hole 21.

[0026] Furthermore, the number of telescopic positioning members 6 is at least four, which are placed at the four corners of the outer panel 2; each telescopic positioning member 6 includes a positioning sleeve 61 and a positioning rod 62 slidably sleeved in the positioning sleeve 61; one end of the positioning rod 62 away from the positioning sleeve 61 is fixedly connected to the inner panel 1, and one end of the positioning sleeve 61 away from the positioning rod 62 is fixedly connected to the outer panel 2; wherein the positioning sleeve 61 and the connecting member 4 are arranged on the same side of the outer panel 2; the sound-absorbing cotton 3 is sleeved on the outer periphery of the positioning sleeve 61.

[0027] The sound-absorbing cotton 3 is sleeved on the outer periphery of the internal threaded sleeve and the positioning sleeve 61 to quickly locate the installation position of the sound-absorbing cotton 3; the spacing between the inner plate 1 and the outer plate 2 is adjusted by the slidingly connected positioning rod 62 and the positioning sleeve 61 to adapt to the sound-absorbing cotton 3 of different thicknesses, thereby meeting different sound insulation requirements; the inner plate 1 and the outer plate 2 are fixedly connected by the cooperation of the countersunk bolts and the internal threaded sleeve, and at the same time, under the action of the positioning rod 62 and the positioning sleeve 61, the relative rotation between the inner plate 1 and the outer plate 2 is limited, thereby preventing the countersunk bolts from detaching from the internal threaded sleeve, thereby ensuring the stability of the fixed connection between the inner plate 1 and the outer plate 2.

[0028] Furthermore, in order to increase the force application points and facilitate the taking of the outer plate 2, a threaded groove 22 is also provided on the outer plate 2, and a handle 7 connected thereto is provided in the threaded groove 22. The end 71 of the handle 7 is a screw handle head, and the tail 72 of the handle 7 is provided with an external thread that matches the internal thread of the threaded groove 22.

[0029] Furthermore, in order to maintain the flatness of the outer panel 2, a countersunk groove 23 is also provided on the side of the threaded through hole 21 away from the inner panel 1. When the inner panel 1 and the outer panel 2 are fixedly connected by countersunk bolts and internally threaded sleeves, the nut of the countersunk bolt is placed in the countersunk groove 23; a decorative sticker 24 for covering the countersunk bolt and the threaded groove 22 is also provided on the outer panel 2.

[0030] Furthermore, a plurality of stickers 8 are bonded to one side of the inner panel 1 away from the sound-absorbing cotton 3, and a sticker protective layer 9 is bonded to the other side of the sticker 8. When the placement position of the inner panel 1 is determined, the sticker protective layer 9 can be torn off and the inner panel 1 can be bonded.

[0031] The working principle of this utility model:

[0032] See also Figure 1-3 , tear off the protective layer 9 of the sticker, so that the inner panel 1 is adhered to the wall through the sticker 8, and the sound-absorbing cotton 3 is sleeved on the outer periphery of the positioning sleeve 61 and the internal threaded sleeve to complete the setting of the sound-absorbing cotton 3, and the positioning rods 61 on the inner panel 1 are respectively inserted into the positioning sleeves 62 corresponding to their positions to prevent the sound-absorbing cotton 3 from falling off and limit the relative rotation between the inner panel 1 and the outer panel 2; the countersunk bolt placed in the threaded through hole 21 of the outer panel 2 is locked with the internal threaded sleeve to fix the inner panel 1 and the outer panel 2. At this time, the nut of the countersunk bolt is placed in the countersunk groove 23, and a decorative sticker 24 that can cover the countersunk bolt and the threaded groove 22 is adhered to the outer panel 2 to maintain the flatness of the appearance of the outer panel 2.

[0033] If the outer panel 2 is damaged, the method of replacing it is as follows: tear off the decorative sticker 24 to expose the countersunk groove 23, use a screwdriver to screw the countersunk bolt to separate the countersunk bolt from the internal threaded sleeve, and then remove the outer panel 2 for replacement. In order to increase the force application point and facilitate the removal of the outer panel 2, the tail 72 of the pinch handle 7 can be screwed into the threaded groove 22 of the damaged outer panel 2, so that the pinch handle 7 is fixedly connected to the outer panel 2. At this time, the force application point is increased by screwing the handle 7 to remove the outer panel 2.
