Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-9 ;

[0027] A high-sealing soundproof door includes a door frame 1, with a door panel 2 hinged vertically to the door frame 1 to enable opening and closing of the door panel 2. The door panel 2 includes an upper connector 3 and a lower connector 4. The upper connector 3 has two first slots 31 and two second slots 32 symmetrically arranged at its top and bottom. The lower connector 4 has two third slots 41 and two fourth slots 42 symmetrically arranged at its top and bottom. The two first slots 31 and two fourth slots 42 are respectively embedded with outer panels 5. The two second slots 32 and two third slots 41 are symmetrically distributed vertically. The second and third slots 41 on the left and right sides are respectively fitted with two outer panels 5. A honeycomb cardboard core 6 is provided between the two outer panels 5 at the top, between the two outer panels 5 at the bottom, and between the two outer panels 5 in the middle. When sound waves pass through the outer panels 5 and enter the interior of the door panel 2, due to the special structure of the honeycomb cardboard core 6, the sound waves will be continuously reflected and attenuated in the honeycomb pores inside, ultimately greatly reducing the sound wave energy and achieving a good sound insulation effect. Preferably, the connectors, outer panel 5 and honeycomb cardboard core 6 are fixedly connected by means of structural adhesive coating or screw fastening to ensure structural stability and sealing during long-term use.

[0028] In addition, a bottom groove 7 is provided between the two lower outer panels 5. The bottom groove 7 is located at the bottom of the lower honeycomb cardboard door core 6. An automatic lifting sealing strip 71 is installed in the bottom groove 7. The structure of the automatic lifting sealing strip 71 can be referred to in the existing patent document "CN215804237U, an automatic lifting device for sealing strips of cleanroom doors", which is also a common product and will not be described in detail here. When the door panel 2 is closed, the sealing strip will automatically descend and contact the ground, effectively sealing the gap between the bottom of the door and the ground, ensuring sealing and sound insulation performance.

[0029] In another embodiment, in order to solve the problem of impact noise that may be generated when the door panel 2 is closed quickly by external force, a fixed plate 11 is provided on the outward side of the door frame 1. Two movable grooves 12 are provided on the fixed plate 11 at intervals. A buffer spring 13 is provided at the bottom of each of the two movable grooves 12. The other end of each of the two buffer springs 13 is connected to a movable block 14. The two movable blocks 14 are respectively movably connected in the corresponding movable grooves 12, and the other end of each of the two movable blocks 14 extends to the outside of the corresponding movable grooves 12. When the door panel 2 rotates in the closing direction, the movable block 14 on the side closest to the hinge of the door panel 2 will first contact the door panel 2. At this time, the door panel 2 pushes the movable block 14 into the movable groove 12, compressing the buffer spring 13 and generating a damping force, thereby initially slowing down the closing speed of the door panel 2. As the door panel 2 continues to rotate and approaches the fully closed state, the movable block 14 on the other side will contact the end of the door panel 2 away from the hinge, compressing another buffer spring 13. The buffer spring 13 applies a secondary damping force, thereby further slowing down the closing speed of the door panel 2, reducing the collision noise between the door panel 2 and the door frame 1, and avoiding the door deformation problem caused by rapid closing, thus extending the service life of the door panel 2.

[0030] In this embodiment, the door panel 2 has a through-hole 21, which serves as a delivery channel for paper express packages or small items. A storage rack 22 is located on the inner side of the door panel 2, with storage space corresponding to and connected to the through-hole for temporary storage of delivered items. The storage rack 22 has an opening at its top, allowing the user to retrieve items from the storage space from the inside of the door. Hinges 23 are symmetrically arranged on the outer side of the door panel 2, positioned below the through-hole 21. Two hinges 23 are hinged together to a cover plate 24, which covers the external opening of the through-hole 21. A fixing member 25 is located below the cover plate 24. The top of the fixing member 25 has a groove 251, and the bottom of the groove 251 has at least one return spring 252. Preferably, this application provides three return springs 252. The other end of the return spring 252 is provided with a sliding bolt 253, which is movably connected in the slide groove 251. The other end of the sliding bolt 253 extends to the outside of the slide groove 251, and its inner wall abuts against the outer wall of the cover plate 24. When it is necessary to deliver an item, the operator can press down the sliding bolt 253 to make it move downward against the elastic force of the return spring 252. At this time, the contact point between the sliding bolt 253 and the cover plate 24 is displaced, causing the cover plate 24 to open around the axis of the hinge 23 under the action of gravity, exposing the delivery port of the strip-shaped through hole 21. After the express delivery or small item is inserted into the through hole, the sliding bolt 253 is released, and the return spring 252 drives the sliding bolt 253 to move upward, thereby driving the cover plate 24 to return to its original position, and finally the cover plate 24 covers the strip-shaped through hole 21 again to prevent the inserted item from being lost.

[0031] In this embodiment, a sealing ring gasket 241 is provided on the inner side of the cover plate 24, and the other side of the sealing ring gasket 241 abuts against the outer wall of the door panel 2 and surrounds the outer periphery of the strip-shaped through hole 21. When the cover plate 24 is in the closed state, the sealing ring gasket 241 and the outer wall of the door panel 2 form a planar seal, which not only ensures the sound insulation effect of the door panel 2, but also prevents external dust or small insects from entering the room through the gaps.

[0032] In this embodiment, a limiting groove 254 is provided on the outer wall of the fixing member 25, which communicates with the sliding groove 251. A limiting rod 255 is provided on the outer wall of the sliding bolt 253. The limiting rod 255 is perpendicular to the sliding bolt 253 and extends through the limiting groove 254 to the outside of the fixing member 25. The outer wall of the limiting rod 255 is in contact with the inner wall of the limiting groove 254. When it is necessary to press down the sliding bolt 253, the user can directly act on the limiting rod 255 to operate. Pressing the limiting rod 255 causes it to move downward vertically, which in turn causes the sliding bolt 253 to move downward against the elastic force of the return spring 252. The top of the limiting groove 254 serves as the highest displacement limit point of the limiting rod 255, effectively controlling the upward stroke of the limiting rod 255. When the return spring 252 pushes the sliding bolt 253 back, the limiting rod 255 cannot exceed the limit position under the constraint of the limiting groove 254, preventing the sliding bolt 253 from dislodging due to excessive spring return force, thus ensuring long-term stable operation.
