Description

Technical Field

[0001] The utility model relates to the technical field of airtight doors, in particular to a radiation-proof airtight door. Background Art

[0002] The radiation-proof door is a radiation protection door mainly used in the medical and nuclear industries. At present, the radiation-proof doors in the industry only focus on the radiation protection function. However, individual departments and hospitals require that the radiation-proof door not only has the radiation protection function, but also has good airtightness. The structure of the radiation-proof airtight door is roughly the same as that of the ordinary radiation-proof door, and both include a door frame with radiation protection function and a door panel with radiation protection function. The door panel and the door frame are connected by a hinged method. In order to improve the airtightness, the radiation-proof airtight door is different from the ordinary radiation-proof door in that: the sealing strip on the door frame in the ordinary radiation-proof door is replaced by an airtight strip with resilience. After the door panel is closed, under the elastic action of the airtight strip, the door panel can be closely attached to the airtight strip, achieving a certain sealing effect.

[0003] The existing radiation-proof airtight doors have the following technical problems: there is a certain gap under the door panel, which affects the overall sealing performance of the radiation-proof airtight door, and electromagnetic waves are easily leaked from this gap. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model provides a radiation-proof airtight door, including: a door frame; a door panel, the door panel is installed on the door frame, and there is a preset gap between the bottom of the door panel and the ground; an automatic lifting sealing strip, the automatic lifting sealing strip is installed at the bottom of the door panel, and the automatic lifting sealing strip is in sealing cooperation with the preset gap; a first lead plate, the first lead plate is arranged between the opposite ends at the bottom of the door frame, and the first lead plate is in shielding cooperation with the preset gap.

[0006] Further, the radiation-proof airtight door further includes: a threshold, the opposite ends of the threshold are respectively connected to the opposite ends at the bottom of the door frame, and the first lead plate is arranged inside the threshold.

[0007] Further, the opposite ends of the threshold are respectively detachably connected to the door frame.

[0008] Further, the door frame has a "door" - shaped structure. The door frame includes a horizontal frame and two vertical frames.

[0030] The utility model provides a radiation-proof airtight door.

[0031] A radiation-proof airtight door comprises: a door frame 1; a door panel 2, the door panel 2 is mounted on the door frame 1, and a preset gap is provided between the bottom of the door panel 2 and the ground; an automatic lifting seal strip 21, the automatic lifting seal strip 21 is mounted on the bottom of the door panel 2, and the automatic lifting seal strip 21 is sealed with the preset gap; a first lead plate 33, the first lead plate 33 is arranged between the opposite ends of the bottom of the door frame 1, and the first lead plate 33 is shielded with the preset gap. The automatic lifting seal strip 21 is a common sealing structure of a flat-opening airtight door, which belongs to the scope of the prior art, and the specific structure and working principle are not described in detail here.

[0032] In the technical solution proposed in the present application, the automatic lifting sealing strip 21 cooperates with the preset gap to ensure the sealing under the door panel 2, and the first lead plate 33 cooperates with the preset gap shielding. Even if the gap under the door panel 2 becomes larger due to the installation of the automatic lifting sealing strip 21, the radiation protection capability under the door panel 2 can be guaranteed. In summary, the automatic lifting sealing strip 21 cooperates with the first lead plate 33 to ensure the sealing under the door panel 2 while ensuring the radiation protection capability under the door panel 2.

[0033] The radiation-proof airtight door further includes a threshold 3, the opposite ends of which are respectively connected to the opposite ends of the bottom of the door frame 1, and a first lead plate 33 is arranged inside the threshold 3. Installing the first lead plate 33 inside the threshold 3 not only facilitates the installation of the first lead plate 33, but also can protect the first lead plate 33 through the threshold 3.

[0034] The opposite ends of the threshold 3 are detachably connected to the door frame 1 respectively. When it is necessary to push something through the radiation-proof airtight door, the threshold 3 can be disassembled to ensure the passability of the radiation-proof airtight door. Since the first lead plate 33 is installed inside the threshold 3, when the threshold 3 is disassembled, the first lead plate 33 will be disassembled together with the threshold 3.

[0035] The door frame 1 is in a "door" shape structure. The door frame 1 includes a horizontal frame 11 and two vertical frames 12. The threshold 3 includes: a first part 31, the first part 31 is in a rectangular box shape structure with an open top. The opposite two side plates of the first part 31 are detachably connected to the bottom sides of the two vertical frames 12 respectively; a second part 32, the top of the first part 31 is buckled with the second part 32 and is detachably connected. In a specific embodiment, the bottom of the first lead plate 33 and the inner bottom of the first part 31 are connected by sealant. Between the opposite two side plates of the first part 31 and the bottom sides of the two vertical frames 12, they are respectively connected by cross recessed countersunk head self-tapping screws 34. The first part 31 and the second part 32 are also connected by cross recessed countersunk head self-tapping screws 34. In order to make the installation of the first lead plate 33 more firm, after the second part 32 and the first part 31 are buckled, the second part 32 and the first lead plate 33 are pressed against each other. The setting of the above structure not only facilitates the detachable connection between the threshold 3 and the door frame 1, but also facilitates the installation of the first lead plate 33.

[0036] The height of the first lead plate 33 is greater than the height of the preset gap. The height of the first lead plate 33 being greater than the height of the preset gap can better realize the shielding cooperation between the first lead plate 33 and the preset gap.

[0037] The door panel 2 is rotatably installed on one side of the door frame 1. An airtight strip is provided on the joint surface of the door frame 1 and the door panel 2, and the airtight strip has a certain resilience. A lock body is provided on the door panel 2, and a lock plate is provided on the door frame 1. The lock body cooperates with the lock plate. The horizontal frame 11 is provided with a second lead plate 111, and the vertical frame 12 is provided with a third lead plate 121. The setting of the second lead plate 111 and the third lead plate 121 enables the door frame 1 to also have radiation-proof ability.

[0038] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. All equivalent structural transformations made under the inventive concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
