[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model embodiment discloses an anti-theft door with a sound insulation structure.

[0028] The utility model provides Figure 1-5 An anti-theft door with a sound insulation structure shown includes a door frame 1 and an anti-theft door body 2, the interior of the anti-theft door body 2 includes a first sound insulation layer 3, a second reinforcement layer 4, a third moisture-proof layer 5 and a fourth sound-absorbing layer 6, a hinge 7 is fixedly connected between the side wall of the anti-theft door body 2 and one side of the interior of the door frame 1, the anti-theft door body 2 is rotatably connected to the door frame 1 through the hinge 7, a groove is provided on the side of the door frame 1 away from the hinge 7, a plurality of buffer mechanisms are arranged at the bottom of the groove, the input ends of the plurality of buffer mechanisms are respectively connected to a fixing plate 8, a buffer pad 9 is fixedly connected to the other side of the fixing plate 8, and rubber pads 10 are arranged around the inner wall of the door frame 1.

[0029] In order to prevent the anti-theft door body 2 from colliding with the door frame 1 when closing, Figure 2 and 3 As shown, the buffer mechanism includes a shell 11, a connecting rod 12, a spring 13 and a limit plate 14, one end of the connecting rod 12 passes through a side wall of the shell 11 and is movably connected to the shell 11, one end of the connecting rod 12 is fixedly connected to the side wall of the fixing plate 8 and the other end of the connecting rod 12 is fixedly connected to the limit plate 14, the spring 13 is movably connected to the rod wall of the connecting rod 12 and the two ends of the spring 13 are respectively fixedly connected to the outer wall of the shell 11 and the side wall of the connecting rod 12.

[0030] When closing the anti-theft door body 2, the outer side of the anti-theft door body 2 contacts the buffer pad 9 and compresses the spring 13 through the fixed plate 8, reducing the force of closing the door, preventing the anti-theft door body 2 from being closed with too much force, which not only creates noise, but also easily causes damage to the anti-theft door body 2 and the door frame 1, and destroys the sound insulation structure inside the anti-theft door body 2 to reduce the sound insulation effect.

[0031] In order to make the anti-theft door body 2 have a sound insulation effect, Figure 4 As shown, the first sound insulation layer 3 is a damping sound insulation board layer, and the fourth sound absorption layer 6 is a glass fiber wool layer.

[0032] When noise is emitted from the outside of the anti-theft door body 2, the damping sound insulation board of the first sound insulation layer 3 can isolate most of the noise, and the remaining noise is absorbed by the glass fiber wool of the fourth sound-absorbing layer 6, which can effectively control noise pollution.

[0033] In order to make the anti-theft door body 2 more solid, Figure 4 and 5 As shown, the second reinforcement layer 4 is an aluminum honeycomb panel, and the internal gap of the second reinforcement layer 4 is filled with a polyurethane foam layer.

[0034] The aluminum honeycomb panel of the second reinforcement layer 4 is strong enough to withstand high-intensity pressure and shear force and is not easily deformed, thereby improving the strength of the anti-theft door body 2 and preventing the anti-theft door body 2 from being damaged. The interior is filled with polyurethane foam which not only further improves the strength but also has a heat preservation effect.

[0035] Finally, in order to prevent the anti-theft door body 2 from rotting due to moisture during long-term use, Figure 4 As shown, the third moisture-proof layer 5 is an activated carbon layer.

[0036] The activated carbon layer of the third moisture-proof layer 5 can absorb the moisture in the anti-theft door body 2 to prevent the anti-theft door body 2 from rotting due to humid air.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
