[0035] The inner side of the door frame 2 has a step for resisting the shielding door leaf 3, and the inner side of the door frame 2 is embedded with a locking device for locking the shielding door leaf 3;

[0036] The edge of the side surface of the shielding door leaf 3 that contacts the inner step of the door frame 2 has a frame-shaped embedding groove 301 , and an inflatable sealing member 9 is embedded in the frame-shaped embedding groove 301 .

[0037] This frictionless acoustic soundproofing door, designed for use in RF-shielded environments, features frictionless opening and closing, effectively reducing doorframe wear and maintaining excellent RF shielding performance. The inflatable seal 9 not only achieves frictionless opening and closing and effective sealing in RF-shielded environments, but also significantly extends the door's service life, reduces noise and vibration, and improves overall operational stability and reliability. Furthermore, its simple structure and easy maintenance significantly reduce long-term operating costs. Therefore, this frictionless acoustic soundproofing door has broad application prospects and market value in applications requiring high RF shielding.

[0038] Specifically, in this embodiment, the inflatable seal 9 is a frame-shaped airbag, and an air pump is fixedly installed on the indoor wall of the shielding room wall door opening 1. One of the air ports of the air pump is connected to the frame-shaped airbag through a bellows. The set air pump is a dual-purpose suction air pump, which is used to inflate and deflate the frame-shaped airbag.

[0039] Specifically, in this embodiment, in order to prevent impurities in the air from entering the frame-shaped airbag and affecting long-term use, an air filter is installed in one of the air ports of the air pump, and in order to reduce the noise when the air pump is working, a muffler is installed in another air port of the air pump.

[0040] Specifically, in this embodiment, the locking device is an electric push rod, and the piston rod of the electric push rod can be inserted into the lock hole on the side of the shielding door leaf 3. When the piston rod of the electric push rod is inserted into the lock hole on the side of the shielding door leaf 3, the shielding door leaf 3 is locked. When the piston rod of the electric push rod is pulled out of the lock hole on the side of the shielding door leaf 3, the shielding door leaf 3 is unlocked.

[0041] Specifically, in this embodiment, in order to facilitate the control of the electric push rod and the operation of the air pump, an outdoor control panel 6 is fixedly installed on the outdoor wall surface of the shielding room wall door opening 1, and an indoor control panel 8 is fixedly installed on the indoor wall surface of the shielding room wall door opening 1. The indoor control panel 8 and the outdoor control panel 6 are both equipped with an air pump control switch for controlling the operation of the air pump and an electric push rod control switch for controlling the operation of the electric push rod.

[0042] Specifically, in this embodiment, in order to prevent the electric push rod from malfunctioning, a contact switch 7 is fixedly installed at a position near the step on the inner side of the door frame 2, and the contact switch 7 is connected in series between the electric push rod and the electric push rod control switch. When the shielding door leaf 3 contacts the contact switch 7, the contact switch 7 is turned on. Only then can the electric push rod be controlled to work, so that the piston rod of the electric push rod can be accurately inserted into the lock hole on the side of the shielding door leaf 3 to achieve the purpose of locking the shielding door leaf 3.

[0043] Specifically, in this embodiment, in order to ensure the shielding effect of the door frame 2 and the shielding door leaf 3 on radio frequency signals, the door frame 2 is a stainless steel door frame, and the surface layer of the shielding door leaf 3 is a stainless steel shielding layer. In order to ensure the sound insulation effect of the shielding door leaf 3, the inner layer of the shielding door leaf 3 is a polyester fiber sound insulation cotton layer.

[0044] Specifically, in this embodiment, the shielding door leaf 3 is hinged in the door frame 2 via the hinge 4 .

[0045] Specifically, in this embodiment, the door frame 2 is fixed to the door opening 1 on the wall of the shielding room by means of bolts.

[0046] Specifically, in this embodiment, in order to facilitate opening and closing of the shielding door leaf 3 , handles 5 are fixedly mounted on both the inner and outer surfaces of the side of the shielding door leaf 3 away from the hinge 4 .

[0047] In summary, the frictionless acoustic soundproofing door provided in this embodiment has the following advantages:

[0048] This frictionless acoustic soundproofing door, designed for use in RF-shielded environments, features frictionless opening and closing, effectively reducing doorframe wear and maintaining excellent RF shielding performance. The inflatable seal 9 not only achieves frictionless opening and closing and effective sealing in RF-shielded environments, but also significantly extends the door's service life, reduces noise and vibration, and improves overall operational stability and reliability. Furthermore, its simple structure and easy maintenance significantly reduce long-term operating costs. Therefore, this frictionless acoustic soundproofing door has broad application prospects and market value in applications requiring high RF shielding.

[0049] When in use, when the shielding door leaf 3 is closed by the handle 5, when the shielding door leaf 3 contacts the contact switch 7, the contact switch 7 is turned on. At this time, the electric push rod control switch is used to control the electric push rod to work, so that the piston rod of the electric push rod is accurately inserted into the lock hole on the side of the shielding door leaf 3 to achieve the purpose of locking the shielding door leaf 3. Then, the air pump control switch is used to control the air pump to work and inflate the frame-shaped air bag, so that the shielding door leaf 3 and the door frame 2 form a better seal. When the door needs to be opened, the air pump control switch is used to control the air pump to work and remove the air in the frame-shaped air bag. Then, the electric push rod control switch is used to control the electric push rod to work, so that the piston rod of the electric push rod is pulled out of the lock hole on the side of the shielding door leaf 3, thereby achieving the purpose of unlocking the shielding door leaf 3. At this time, the shielding door leaf 3 can be pulled open toward the door opening 1 on the wall of the shielding room outside through the handle 5.
