Technical Field
[0001] The utility model relates to the technical field of radiation-proof doors, in particular to a radiation-proof door capable of preventing pinching. Background Art
[0002] Radiation-proof doors, also known as ray protection doors or medical radiation-proof doors, are mainly used in places such as hospital radiology departments where it is necessary to prevent radiation from causing harm to the human body. They are usually composed of door leaves with embedded lead plates and airtight door frames. Lead is a substance with a higher atomic number in nature and has a good shielding effect on radiation. Radiation-proof doors can be divided into many types. According to the opening power, they can be divided into manual doors and automatic doors; according to the opening method, they can be divided into sliding doors and translation doors. Anti-pinch radiation-proof doors are a specially designed protective device that aims to provide radiation protection while ensuring the safety of users and avoid pinching hands or other body parts during the closing process.
[0003] Existing radiation-proof doors use a telescopic rod and a spring to decelerate. However, as the use time increases, the spring will be oxidized and corroded in the air, causing its elasticity to weaken. This will cause the spring and telescopic rod to be unable to decelerate in time when the radiation-proof door is closed, thereby increasing the risk of people being pinched. Therefore, those skilled in the art have provided a radiation-proof door that is anti-pinching to solve the problems raised in the above background technology. Utility Model Content

The internal gas of the sealing airbag will be discharged through the exhaust pipe to avoid over-inflation of the sealing airbag, so that the sealing airbag can fit tightly into the gap between the door frame and the radiation-proof door body, thereby improving the sealing and radiation-proof effect.
