Description
Technical field
It the utility model is related to radiation protection equipment field, and in particular to a kind of radiation proof door lock cover.
Background technology
According to GB18871 1《Ionization radiation protection and the safe basic standard of radiation source》, to being put with medical radiation
Penetrate and the exposure room indoor wall of commercial plant, wall top, door and window, ventilating opening etc. can be accomplished effectively to protect, but to exposure
The room leakage radiation that is formed of protection door lock can not but be accomplished effectively to protect, and this, which is primarily due to do protection, can influence to unlock.
The protection door lock in China's radiation protection field is in the present situation do not done and protected for many years, and this causes staff and patient or attached
Near people is injured by radiation exposure unavoidably, and this hidden danger is not detected or given tacit consent to about detection and supervision department can not do herein
Protection.
The common x ray room of Hospitals at Present, DR rooms, CT Room, linear accelerator room, DSA rooms, c-type cover room, nuclear-magnetism screened room etc.
Radiation chamber, and industrial flaw detection room, the door lock of its radiation door are divided to two kinds, and a kind of is the Fire-proof lock of vertical hinged door, and one kind is to move
The Tiandi lock of dynamic door, both door locks are all to have to punch door body to install, and when mounted, punch the fixing hole of door body extremely
3-4 are needed less, then adds keyhole to need 4-5 lockholes to need to protect altogether, are not protected, ray necessarily penetrates these lockholes；
And protect, can cause again door lock be closed and can not it is normally-open and close.
Utility model content
In order to overcome above-mentioned technical deficiency, the utility model provides a kind of radiation proof door lock cover, can be to radiation-retarding door
Lockhole is shielded, and improves the protection effect of radiation-retarding door.
Technical scheme is used by the utility model solves its technical problem：A kind of radiation proof door lock cover, including cover body,
Rectangular parallelepiped structure is fixedly connected between the front side board of cover body, left plate, right plate, upper plate and lower plate, after the upper plate of cover body
Side is flexibly connected hinge, and the left plate or right plate of cover body are provided with a L-type notch, and the part of L-type notch is to after cover body
Side extends and is provided with openend, and another part of L-type notch is provided with sealing end；The inside of the cover body is provided with radiation proof stereotype.
Further, the cover body can be by stainless steel plate or the shaping of metallic paint plate weld or by soffening
Material compression molding.
Further, the L-type notch is provided with the part of openend with the top plate of cover body to be arranged in parallel, and L-type notch is set
There is the top plate of the part of sealing end and cover body to be vertically arranged.
The beneficial effects of the utility model are the radiation proof door lock covers, are arranged on by hinge on the door lock of radiation-retarding door,
Cover body covers door lock, and because ray is along straightline propagation, cover body can be by through the alpha ray shield of door lock fixing hole, door lock handle
Hand can rotate to shake by L-type notch realizes enabling, door-closing operation, and cover body is rotated to lift by hinge exposes lock core hole,
Realize the opening and closing of door lock；Door lock does not influence to change when damaging, and can realize enabling in the closed state and close the door.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is scheme of installation of the present utility model.
Indicated in figure, 1. cover bodies, 2. hinges, 3.L type groove mouths, 4. lock cores, 5. door lock handles.
Embodiment
Reference picture 1-2, a kind of radiation proof door lock cover, including cover body 1, front side board, left plate, right plate, the upper plate of cover body 1
Rectangular parallelepiped structure is fixedly connected between lower plate, the rear side of the upper plate of cover body 1 installs hinge 2 by screw, enables cover body 1
Spin upside down；The right plate of cover body 1 is provided with a L-type notch 3, and a part for L-type notch 3 is parallel with the top plate of cover body 1, this
A part extends to the rear side of cover body 1 and is provided with opening in the rear side of right plate；Another part of L-type notch 3 and the top plate of cover body 1
Vertically, the lower section of this part of plate to the right extends and is provided with sealing end；The cover body 1 is welded by stainless steel plate, cover
The inside of body 1 is provided with radiation proof stereotype.
In actual applications, hinge 2 be arranged on radiation-retarding door door lock above, cover body 1 by lock core 4, door lock handle 5 and
The fixing hole that installation door lock is punched is covered, and door lock spanner 5 is exposed outside cover body 1 by L-type notch 3, and door lock handle 5 can be by setting
A part of notch for having sealing end rotates up and down, realizes and opens the door；Because L-type notch 3 is provided with opening on rear side of cover body 1, by cover body 1
