Lock shield for antiradiation door

Abstract

The invention discloses a lock shield for an antiradiation door. The lock shield comprises a shield body, wherein a front side plate, a left side plate, a right side plate, an upper plate and a lower plate of the shield body are fixedly connected into a cuboid structure, the rear side of the upper plate of the shield body is movably connected to a hinge, the left side plate or right side plate of the shield body is provided with an L-shaped notch, one part of the L-shaped notch extends to the back side of the shield body and is provided with an open end, and the other part of the L-shaped notch is provided with a sealing end; and an antiradiation lead plate is arranged in the shield body. The lock shield is mounted on a door lock of the antiradiation door by the hinge, the shield body covers the door lock, since rays are transmitted along a straight line, the shield body can shield the rays penetrating through a fixing hole of the door lock, a door lock handle can realize door opening and closing operations by rotating and shaking the L-shaped notch, the shield body is rotated and turned over upwards by the hinge to expose a lock cylinder hole, thereby realizing unlocking and locking of the door lock; and replacement is not affected when the door lock is damaged, and the door opening and closing under a closing state can be realized.

Description

technical field [0001] The invention relates to the field of radiation protection equipment, in particular to a radiation-proof door lock cover. Background technique [0002] According to GB18871-2002 "Basic Standards for Ionizing Radiation Protection and Radiation Source Safety", effective protection can be achieved for the indoor walls, wall tops, doors, windows, and vents of the exposure room with medical radiation and industrial equipment, but The radiation leakage formed by the protective door lock of the exposure room cannot be effectively protected, mainly because the protection will affect the unlocking. For many years, the protective door locks in the field of radiation protection in my country have been in the status quo without protection, which makes it inevitable for staff, patients or people nearby to be harmed by radiation exposure. The relevant inspection and supervision departments do not detect this hidden danger or default here. Do protection. [0003] At...

Problems solved by technology

[0002] According to GB18871-2002 "Basic Standards for Ionizing Radiation Protection and Radiation Source Safety", effective protection can be achieved for the indoor walls, wall tops, doors, windows, vents, etc. of the exposure room with medical radiation and industrial equipment, but The radiation leakage formed by the protective door lock of the exposure room cannot be effectively protected, mainly because the protection will affect the unlocking.

For many years, the protective door locks in the field of radiation protection in my country have been in the status quo without protection, which makes it inevitable for staff, patients or nearby people to be harmed by radiation exposure. The relevant inspection and supervision departments do not detect this hidden danger or default here. do protection

[0003] At present, X-ray rooms, DR rooms, CT rooms, linear accelerator rooms, DSA rooms, C-type shielding rooms, nuclear magnetic shielding rooms and other radiation rooms common in hospitals, as well as industrial flaw detection rooms, have two types of door locks for the radiation protection doors. One is the fireproof lock of the swing door, and the other is the heaven and earth lock of the mobile door. These two kinds of door locks must penetrate the door body to be installed. During installation, at least 3-4 fixing holes are required to penetrate the door body. , plus the keyhole, a total of 4-5 lockholes need to be protected. Without protection, the rays must penetrate these lockholes; and with protection, the door lock will be closed and cannot be opened and closed normally.
