Description

Technical Field

[0001] The utility model relates to the technical field of radiation protection doors, in particular to a middle door structure of a medical automatic radiation protection door. Background Technique

[0002] The radiation protection door in the radiology department of a hospital is a specially designed door used to prevent the leakage of radiation to other areas. The radiation protection door in the radiology department usually uses materials such as lead plates or lead glass because lead can effectively block or absorb most of the radiation to ensure that the radiation does not leak through the door gap. However, due to its relatively heavy weight, the automatic moving radiation protection door is a commonly used radiation protection door.

[0003] Since the automatic radiation protection door is too heavy, it is difficult to manually open it suddenly after a power outage, resulting in difficulties for medical staff to enter and exit conveniently, posing a safety hazard. Therefore, we propose a middle door structure of a medical automatic radiation protection door to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that the automatic radiation protection door is too heavy, making it difficult to manually open it suddenly after a power outage and causing difficulties for medical staff to enter and exit conveniently, and to propose a middle door structure of a medical automatic radiation protection door.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A middle door structure of a medical automatic radiation protection door, including an electric guide rail assembly and an embedded ground trench. One side of the electric guide rail assembly is fixedly arranged above the opening of the wall body. The bottom of the electric guide rail assembly is provided with a main door leaf door frame. The embedded ground trench is embedded in the ground at the opening of the wall body, and the embedded ground trench is slidably connected to the bottom of the main door leaf door frame. This automatic radiation protection door further includes:

[0007] A radiation protection moving door, which is arranged on the inner wall of the main door leaf door frame to prevent radiation leakage;

[0008] A middle door assembly, which is arranged on the main door leaf door frame to facilitate medical staff to enter and exit through the middle door after a power outage.

[0009] In a possible design, the radiation protection moving door includes a front door panel and a back door panel. The front door panel and the back door panel are fixedly arranged on the inner wall of the main door leaf door frame. An invisible handle is arranged on the outer side of the front door panel. A flame retardant board, a radiation protection lead plate, and an aluminum honeycomb are fixedly arranged between the front door panel and the back door panel on the inner wall of the main door leaf door frame. The flame retardant board is close to the side of the back door panel. The radiation protection lead plate is located between the flame retardant board and the aluminum honeycomb. The aluminum honeycomb is located between the radiation protection lead plate and the front door panel, and a door opening is provided on the radiation protection moving door.

[0010] In a possible design, the inner-door component of the door includes an inner skeleton, which is fixedly arranged on the door opening. An anti-radiation inner-door frame is fixedly arranged on the inner wall of the inner skeleton. An anti-radiation inner-door leaf is hinged to one side of the anti-radiation inner-door frame. A plurality of closing components for automatically closing the anti-radiation inner-door leaf are arranged at equal intervals on the anti-radiation inner-door frame and the anti-radiation inner-door leaf.

[0011] In a possible design, the closing component includes a fixing plate, which is fixedly arranged on one side of the anti-radiation inner-door frame. A fixing tube is fixedly connected to one side of the fixing plate. A rotating rod is rotatably penetrated through the fixing tube. Both ends of the rotating rod are fixedly connected to the same moving plate, and the moving plate is fixedly connected to one side of the anti-radiation inner-door leaf. A torsion spring is sleeved on the rotating rod, and both ends of the torsion spring are fixedly connected to the rotating rod. A limiting block is fixedly connected to the inner wall of the fixing tube, and the protruding end of the torsion spring is placed on one side of the limiting block.

[0012] In a possible design, the internal composition material of the anti-radiation inner-door leaf is the same as that of the anti-radiation moving door.

[0013] In a possible design, a plurality of rotating wheel axles are fixedly connected to the bottom of the main door leaf frame, and bottom rails rollers are arranged at the bottom ends of the plurality of rotating wheel axles. The plurality of bottom rails rollers all slide on the inner wall of the bottom of the embedded rail groove.

[0014] In a possible design, a floor lock is arranged at the bottom of one side of the anti-radiation moving door, which is used to fix the lower swing of the anti-radiation moving door and improve the stability of the opening of the anti-radiation inner-door leaf in the inner-door component of the door.

[0015] In this application, in the normal working state, the anti-radiation moving door is automatically opened and closed by the drive of the electric guide rail assembly, effectively preventing the leakage of radiation. The anti-radiation moving door is composed of a front door panel, a back door panel, a flame retardant board, an anti-radiation lead board and an aluminum honeycomb. The combination of these materials makes the door have excellent anti-radiation performance and flame retardant performance.

[0016] In the inner-door component part of the door, the anti-radiation inner-door frame is fixed on the door opening through the inner skeleton. The anti-radiation inner-door leaf is connected to the anti-radiation inner-door frame through a hinge. Under the action of the closing component, the anti-radiation inner-door leaf can automatically close, ensuring the sealing performance of the door. The closing component is composed of a fixing plate, a fixing tube, a rotating rod, a moving plate, a torsion spring and a limiting block.

Specifically, the radiation-proof movable door includes a front door panel 2 and a back door panel 9, both of which are fixedly arranged on the inner wall of the main door leaf door frame 8. In order to facilitate medical staff to quickly open the radiation-proof movable door in case of emergency, a hidden handle 6 is arranged on the outer side of the front door panel 2. On the inner wall of the main door leaf door frame 8, between the front door panel 2 and the back door panel 9, a flame-retardant board 10, a radiation-proof lead board 11 and an aluminum honeycomb 12 are fixedly arranged. Among them, the flame-retardant board 10 is on the side close to the back door panel 9 to improve the fire resistance of the door body; the radiation-proof lead board 11 is located between the flame-retardant board 10 and the aluminum honeycomb 12 to block the leakage of radiation, and the aluminum honeycomb 12 is located between the radiation-proof lead board 11 and the front door panel 2 to provide the light weight and structural strength of the door body. In addition, a door opening is provided on the radiation-proof movable door to facilitate the installation of the door-in-door assembly.

[0035] The door-in-door assembly is another key part of this embodiment. This assembly is arranged on the main door leaf door frame 8 to facilitate medical staff to enter and exit through the middle door in case of emergency such as power failure. The door-in-door assembly includes an inner skeleton 13, which is fixedly arranged on the door opening. The inner wall of the inner skeleton 13 is fixedly provided with a radiation-proof middle door frame 3. One side of the radiation-proof middle door frame 3 is hinged with a radiation-proof middle door leaf 4. In order to ensure that the radiation-proof middle door leaf 4 can automatically close when there is no one to operate, a plurality of closing assemblies are arranged at equal intervals on the radiation-proof middle door frame 3 and the radiation-proof middle door leaf 4.
