The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, a kind of handle door opener of electromagnetic shield door, comprise thread bush 2, nut sleeve 3, supporting cover 11, seat cushion circle 9, handle head 1, handlebar 13 and two ends have the Handle axis 6 of square toes, handle head 1 is enclosed within on the square toes of Handle axis 6 and with Handle axis 6 fixedlys connected, one end of handlebar 13 is inserted in the handle head 1, thread bush 2 and nut sleeve 3 are by being threaded, thread bush 2 is fixedlyed connected with shield door 17 by the hole on the shield door, supporting cover 11 is fixedlyed connected with shield door 14, seat cushion circle 9 is fixed on the supporting cover 11, Handle axis 6 is passed thread bush 2, nut sleeve 3 and supporting pad 9, and Handle axis 6 is bearing on the nut sleeve 3 by clutch shaft bearing 15, Handle axis 6 is by second bearing 15 ' be bearing on the seat cushion circle 9, be set with disc type reed 8 on the Handle axis 6 between thread bush 2 and the clutch shaft bearing 15, disc type reed 8 is bearing on the step of Handle axis 6, also be provided with metallic gasket 5 between thread bush 2 and the Handle axis 6, wire lath sealing mat 5 is sleeved on the Handle axis 6, be provided with tamponade 4 in the hole of thread bush 2, tamponade 4 is sleeved on the Handle axis 6, and the lower end of tamponade 4 props up metallic gasket 5.
As shown in Figure 1, handle head 1 is fixedlyed connected with the square toes of Handle axis 6 by stopping screw 16.
Operating principle of the present utility model is as follows:
According to the local movable span of metallic shield body slit principle of electromagnetic shield-ing: if want local movable span slit to obtain to be equivalent to effect when seamless, then deep thickness must be worn quite or allow repeatedly catadioptric of electromagnetic wave with electromagnetic in metal plate hole slit.These two kinds of measures all are used in structure design of the present utility model, and as dose wire lath sealing mat and disc type reed in the axis hole crack, shielding properties is much improved than original handle door opener.
