Abstract
The invention discloses a kind of radiation protection door lock covers, including cover, rectangular parallelepiped structure is fixedly connected between the front side board of cover, left plate, right side plate, upper plate and lower plate, the rear side of the upper plate of cover is flexibly connected hinge, the left plate or right side plate of cover are equipped with a L-type notch, a part of L-type notch is to extension on rear side of cover and is equipped with open end, and another part of L-type notch is equipped with sealing end；The inside of the cover is equipped with radiation protection stereotype.The present invention is mounted on the door lock of radiation-retarding door by hinge, cover covers door lock, since ray is along straightline propagation, cover can pass through the alpha ray shield of door lock fixation hole, door lock handle, which can rotate to shake by L-type notch, realizes enabling, door-closing operation, expose lock core hole by lifting in hinge rotation cover, realizes the opening and closing of door lock；Door lock does not influence to replace when damaging, and can realize enabling and shutdown in the closed state.
Description
Technical field
The present invention relates to radiation protection equipment fields, and in particular to a kind of radiation protection door lock cover.
Background technique
According to GB18871 1 " ionization radiation protection and the safe basic standard of radiation source ", put to medical radiation
It penetrates and the exposure room indoor wall of commercial plant, wall top, door and window, ventilation opening etc. can be accomplished effectively to protect, but to exposure
Room protection door lock is formed by leakage radiation and cannot but accomplish effective protection, this, which is primarily due to do protection, will affect unlocking.
The protection door lock in China's radiation protection field is in and does not do the status protected for many years, this makes staff and patient or attached
Close people is inevitably injured by radiation exposure, and not detecting or defaulting to this hidden danger in relation to detection and supervision department can not do herein
Protection.
The common x ray room of Hospitals at Present, the room DR, CT Room, linear accelerator room, the room DSA, c-type cover room, nuclear-magnetism screened room etc.
Radiation chamber and industrial flaw detection room, the door lock of radiation door are divided to two kinds, and one is the Fire-proof locks of vertical hinged door, and one is shiftings
The Tiandi lock of dynamic door, both door locks are all to have to punch door body to install, and during installation, punch the fixation hole of door body extremely
Need 3-4 less, then plus keyhole need 4-5 lockholes to need to protect altogether, do not protect, ray necessarily penetrates these lockholes；
And protect, and will cause door lock be closed and cannot it is normally-open and close.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the present invention provides a kind of radiation protection door lock cover, can be to the lockhole of radiation-retarding door
It is shielded, improves the protection effect of radiation-retarding door.
The technical solution adopted by the present invention to solve the technical problems is: a kind of radiation protection door lock cover, including cover, cover
Front side board, left plate, right side plate, rectangular parallelepiped structure is fixedly connected between upper plate and lower plate, the rear side of the upper plate of cover is living
Dynamic connects hinge, the left plate or right side plate of cover are equipped with a L-type notch, and a part of L-type notch is prolonged to cover rear side
Open end is stretched and is equipped with, another part of L-type notch is equipped with sealing end；The inside of the cover is equipped with radiation protection stereotype.
Further, the cover can be by stainless steel plate or metallic paint plate welding fabrication, be also possible to by soffening
Material compression molding.
Further, it is to be arranged in parallel that the L-type notch, which is equipped with the part of open end with the top plate of cover, and L-type notch is set
The top plate for having the part of sealing end and cover is to be vertically arranged.
The invention has the advantages that the radiation protection door lock cover, is mounted on the door lock of radiation-retarding door, cover by hinge
Door lock is covered, since ray is along straightline propagation, cover can pass through the alpha ray shield of door lock fixation hole, and door lock handle can
It rotates to shake by L-type notch and realizes enabling, door-closing operation, expose lock core hole by lifting in hinge rotation cover, realize
The opening and closing of door lock；Door lock does not influence to replace when damaging, and can realize enabling and shutdown in the closed state.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is scheme of installation of the invention.
It is indicated in figure, 1. covers, 2. hinges, 3.L type groove mouth, 4. lock cores, 5. door lock handles.
Specific embodiment
Referring to Fig.1-2, a kind of radiation protection door lock cover, including cover 1, front side board, left plate, right side plate, the upper plate of cover 1
Rectangular parallelepiped structure is fixedly connected between lower plate, the rear side of the upper plate of cover 1 installs hinge 2 by screw, enables cover 1
It spins upside down；The right side plate of cover 1 is equipped with a L-type notch 3, and a part of L-type notch 3 is parallel with the top plate of cover 1, this
A part is equipped with opening to extension on rear side of cover 1 and in the rear side of right side plate；Another part of L-type notch 3 and the top plate of cover 1
Vertically, the lower section of this part of plate to the right extends and is equipped with sealing end；The cover 1 is welded by stainless steel plate, cover
The inside of body 1 is equipped with radiation protection stereotype.
In practical applications, hinge 2 is mounted on above the door lock of radiation-retarding door, cover 1 by lock core 4, door lock handle 5 and
The fixation hole that installation door lock is punched covers, and door lock spanner 5 is exposed outside cover 1 by L-type notch 3, and door lock handle 5 can be by setting
There is a part of notch of sealing end to be rotated up and down, realizes and open the door；Since L-type notch 3 is equipped with opening on rear side of cover 1, by cover 1
Door lock handle 5 can be detached from cover 1 when being flipped up by hinge 2, expose lock core 4, locked a door with key.
