It is shielding cloth between end.
Further, ventilation waveguide window, power-supply filter and traffic filter are provided with the motor shield shell.
Further, the electromagnetic protection structure also includes protective stent, and the protective stent is bellows, the protection branch
The two ends of frame are respectively fixedly disposed at the both ends of the motion parts of motion pole.
Further, the junction between the motor shield shell and the shell for driving rod member passes through after setting conductive gasket
Screw is fixed.
Further, the motion pole protective cover is provided with fixed shell with the junction of rod member cage connection is driven, institute
State fixed shell and drive the junction between rod member shell to be fixed by screw after conductive gasket is set.
Further, the motion pole protective cover is provided with fixed support with the junction of motion pole end, described solid
Fixed rack is fixed after setting conductive gasket with the junction of motion pole end by screw.
The present invention has following Advantageous Effects：
The electromagnetic protection structure of the application has versatility, and shield shell is modular construction, convenient disassembly；Due to driving
There is relative motion in rod member, the application is shielded at relative motion using flexible shielding material；Shielding material one end is consolidated
Due to the shell for having relative motion with rod member, the other end is fixed on motion rod member end, and shielding material is moved with rod member；Can be effective
The leakage of signal is avoided interference, good shield effectiveness has been reached.Because the structure of the application can not only realize good electricity
Magnetic screen, moreover it is possible to realize good environmental protection, so be particularly suitable for working in the presence of a harsh environment, to electromagnetic shielding requirements compared with
Situation high, such as radio astronomy, aviation and naval vessel field.

Specific embodiment
Below, refer to the attached drawing, is more fully illustrated to the present invention, shown in the drawings of exemplary implementation of the invention
Example.However, the present invention can be presented as various multi-forms, the exemplary implementation for being confined to describe here is not construed as
Example.And these embodiments are to provide, so that the present invention is fully and completely, and will fully convey the scope of the invention to this
The those of ordinary skill in field.
As Figure 1-4, invention provides a kind of electromagnetic protection structure of driving rod member, the electromagnetic protection structure bag
Include motor shield shell 1 and motion pole protective cover 2；Wherein, motor shield shell 1 is connected with the shell 3 of rod member is driven；Motion
One end of pole protective cover 2 is fixed on the shell 3 for driving rod member, and the other end is fixed on the motion pole end for driving rod member；
It is shielding cloth 4 between the both ends of motion pole protective cover 2.
Ventilation waveguide window 5, power-supply filter 6 and traffic filter 7 are provided with motor shield shell 1.
For in preventing moving lever motion process, shielding cloth disturbs the proper motion of rod member, electromagnetic protection structure also to include anti-
Shield support 8, protective stent 8 is bellows, and the two ends of protective stent 8 are respectively fixedly disposed at the two of the motion parts of motion pole
End.
Junction between motor shield shell 1 and the shell 3 for driving rod member is consolidated after setting conductive gasket 9 by screw 10
It is fixed.
Motion pole protective cover 2 is provided with fixed shell 11, fixed shell 11 with the junction for driving rod member shell 3 to be connected
