Description
Technical field
The utility model relates to medical imaging devices, are more particularly to a kind of cabinet Simple electromagnetic shielding cover board structure.
Background technique
In large-scale visual medical equipment, the electric component such as power control cabinet, computer housing, these electronics have been generally comprised
Electric component is both needed to meet certain electromagnetic shielding demand, could work normally under circumstances.It therefore need to be to these electronics
Cabinet where electricity piece does corresponding electromagnetic shielding measure, and the door of cabinet is protected in research and development debugging stage and subsequent maintenance
It needing often to open and close during supporting, the electromagnetic shielding measure between cabinet and door is particularly important, for large-scale visual medical equipment,
The usually production of small lot, and the labyrinth of some electromagnetic shield doors usually requires out particular manufacturing craft, higher cost.Therefore
It designs a kind of cabinet and shields door with Simple electromagnetic and be of great significance, the shielding cover board structure of existing cabinet: one is
Groove and protrusion are opened up on cover board and cabinet, is generated centainly when closing cover board and cabinet by some card slot fit structures
Pressing force makes cover board and cabinet form continuous electric conductor by the conductive seal item being set between the two.Another kind is straight
Connect and cover board and conductive seal item be pressed on cabinet by the way of screw fastening, there are the problem of: first way is usual
With more complex structure, special metal plate punching mold is needed out, the higher cost for the case where small lot produces.The
Two kinds of modes need to be arranged the engagement that a large amount of screw hole location is evenly arranged on cabinet and cover board for biggish chassis cover
Place, is not easy to debugger routine, maintenance.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of cabinet use convenient for debugger routine, maintenance
Simple electromagnetic shielding cover board structure.
To achieve the above object, the utility model provides following technical solution: a kind of cabinet Simple electromagnetic screening cover
Hardened structure, including cabinet and cover board, the cabinet are equipped with the bending edges bent inwardly on one side, and in addition three sides are equipped with inwardly
The top surface of the right angle flange of bending, the bottom surface of the bending edges and three right angle flange is equipped with conductive seal item, the cover board
On one side be equipped with latch, in addition three sides be equipped with bend inwards and with the one-to-one ruffle of right angle flange, the latch
Threaded hole corresponding with position is offered on cabinet, the threaded hole is interior to be equipped with screw, the bottom surface to right angle of the bending edges
The distance of flange top surface is less than twice of conductive seal thickness and the sum of the thickness at the ruffle of cover board.
The further threaded hole sets there are two and is located at the both ends of latch.
The width of the further right angle flange is 8mm-10mm.
In conclusion the utility model utilizes simple metal plate bending, ruffle technique and two screw fasteners completions pair
Compression between cover board and cabinet, and without occupying excessive box opening region area, it is convenient for debugger routine, maintenance.

Specific embodiment
A kind of embodiment of cabinet Simple electromagnetic shielding cover board structure of the utility model is made into one referring to figs. 1 to Fig. 4
Walk explanation.
A kind of cabinet 2 structure of Simple electromagnetic shielding cover board, including cabinet 1 and cover board 2, the cabinet 1 are equipped on one side
The bending edges 13 bent inwardly, in addition three sides are equipped with the right angle flange 3 to bend inwards, the bottom surface and three of the bending edges 13
The top surface of a right angle flange 3 is equipped with conductive seal item 12, and the cover board 2 is equipped with latch 21 on one side, in addition sets on three sides
Bend inwards and with the one-to-one ruffle 21 of right angle flange 3, it is corresponding that position is offered on the latch 21 and cabinet 1
Threaded hole, be equipped with screw 3 in the threaded hole, the distance of the bottom surface of the bending edges 13 to 3 top surface of right angle flange is less than leading
Twice of electric 12 thickness of sealing strip with the sum of the thickness at the ruffle 21 of cover board 2.
The ruffle 21 of cover board 2 is against to the 3 conductive seal item 12 of right angle flange of cabinet 1, case is inserted into 2 one end of cover board when installation
In the bending edges 13 of body 1, keep latch 21 opposite with the fitting of cabinet 1 and the position of threaded hole, the sealing of 2 compression conductive of holddown plate
Item 12, locks that two screws were both detachable, and the ruffle 21 in the present embodiment can also reinforce 2 rigidity of cover board, is not easy when compressing
Deformation is completed using simple metal plate bending, 21 technique of ruffle and two 3 fasteners of screw to the pressure between cover board 2 and cabinet 1
Tightly, and without occupying excessive 1 open areas of cabinet, it is convenient for debugger routine, maintenance.
Preferably the threaded hole sets there are two and is located at the both ends of latch 21, two screw lockings the present embodiment
It is firm, and operate simple.
The width of the preferred right angle flange 3 of the present embodiment is 8mm-10mm, and too long easy waste material, which increases, to be processed
Difficulty, the too short installation dimension for not being able to satisfy conventional conductive seal item 12.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
