Hot chamber provides a highly safe working environment for operators through its special structure and protective facilities. Hot chamber is provided with operating hand hole, dosing lifting etc. to reduce the radiation dose of workers during subpackaging operation. The operating hand hole of hot chamber is used for operating glove, and the operating hand hole can also be called glove mouth.

[0003] In order to better prevent radiation, protective cover is installed at the hole position of glove mouth of hot chamber. The protective cover is a round cover structure matched with the hole position of glove mouth. However, the connection between the protective cover and the glove mouth still has a straight gap that can allow radiation to be emitted, so that the effect of radiation prevention is poor. Therefore, the present application designs a radiation protection glove mouth cover mechanism to improve the effect of radiation prevention. SUMMARY

[0004] In order to solve the above technical problems, the utility model provides a kind of radiation protection glove mouth cover mechanism, which effectively blocks the radiation emitted by radiation source in box by multiple groups of protective blocks with different thickness and taper angle on the inner side of protective cover.

[0005] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0006] A radiation protection glove mouth cover mechanism, characterized by comprising a protective cover, the protective cover is installed at the glove mouth position of the radiation protection door, the inner side of the protective cover is provided with multiple groups of protective blocks arranged in a stepped manner, the adjacent protective blocks are connected integrally, and the outer surface of the protective block is provided with a conical surface structure,

[0007] One end of the protective cover is rotatably installed on the radiation protection door by a rotating shaft.

[0008] Specifically, the protective cover is made of professional radiation-proof lead material.

[0009] Specifically, the radiation protection door is installed on the box of hot chamber.

[0010] The utility model has the advantages of:

[0011] The utility model discloses a protective cover is rotatoryly installed in the glove port position department of the radiation protection door, and the rotatory protective cover can adjust the glove port to be opened and closed, and the protective blocks with the conical surface structure are arranged on the inner side of the protective cover in the form of ladder, and the radiation from the radiation source in the hot chamber is effectively blocked by the protective blocks with different thickness and taper angle, because the radiation is ray, so the radiation does not exist the circuitous route, and the protective cover and the glove port of the radiation protection door are connected by the multiple groups of inflection points of the protective blocks arranged in the form of ladder, so that the radiation can be better blocked to realize the effective radiation protection.
