Describe in detail below in conjunction with accompanying drawing.

Please refer to FIG. 1 to FIG. 3 , which are a three-dimensional schematic diagram, another three-dimensional schematic diagram and a side view of an embodiment of the opening structure of the signal isolation box cover of the present invention. As shown in the figure, the signal isolation box 1 of the present utility model is preferably made of a metal material having an appropriate thickness, and includes an isolation box 10, an isolation cover 20 and at least one cover opening mechanism 30, The top of the isolation box 10 has at least one opening 11 , and at least one hinge 12 is provided at one edge of the opening 11 of the isolation box 10 .

The isolation cover 20 is pivotally connected to one side edge of the opening 11 of the isolation box 10 through a hinge 12, and can be tightly closed to the opening 11 of the isolation box 10, so that when the isolation cover 20 is tightly closed to the isolation box When the opening 11 of 10 is used, an electromagnetic wave-tight space can be formed inside the isolation box 10 .

The cover opening mechanism 30 is correspondingly connected and arranged on one side 21 of the isolation cover 20 on both sides of the hinge 12 and on the surface of the side plate 13 of the isolation box 10, so that under the actuation of the cover opening mechanism 30, the The isolation cover 20 is opened or closed from the opening 11 of the isolation box 10 , and the cover opening mechanism 30 includes a first connecting rod 31 , a second connecting rod 32 and a pneumatic cylinder 33 respectively.

One end of the first link 31 is pivotally connected to a first pivot 34 on the side 21 of the isolation cover 20, and one end of the second link 32 is pivotally connected to a second pivot on the side plate 13 of the isolation box 10. The shaft 35, the other end of the first connecting rod 31 and the second connecting rod 32 are pivotally connected to each other on a fixed shaft 36, and the air cylinder 33 is pivotally arranged on a third pivot 37 on the side plate 13 of the isolation box 10 , the end of a telescopic rod 331 of the pneumatic cylinder 33 is pivotally connected on the second connecting rod 32 between the second pivot 35 and the fixed shaft 36, so that when the isolation cover 20 is intended to be opened from the isolation box 10, Through the action of the pneumatic cylinder 33, the telescopic rod 331 of the pneumatic cylinder 33 can be extended outwards, and the first connecting rod 31 and the second connecting rod 32 can be simultaneously driven to generate interlocking movement so that the isolation cover takes the hinge 12 as the axis The core rotates and opens an appropriate angle upwards; on the contrary, when the isolation cover 20 is intended to be closed from the isolation box 10, the telescopic rod 331 of the pneumatic cylinder 33 can be contracted inwardly by the action of the pneumatic cylinder 33, and simultaneously drive The first connecting rod 31 and the second connecting rod 32 are interlocked so that the isolation cover 20 rotates around the hinge 12 and closes toward the opening 11 of the isolation box 10 .

Please refer to FIG. 4 , which is a schematic diagram of the action when the isolation cover of an embodiment of the signal isolation box of the present invention is opened. As shown in the figure, when the isolation cover 20 of the signal isolation box 1 of the present utility model is opened from the isolation box 10, the pneumatic cylinder 33 is first activated, and when the telescopic rod 331 of the pneumatic cylinder 33 is extended outward At this time, the telescopic rod 331 will push the second connecting rod 32 to rotate upwards with the second pivot 35 as the axis, and when the second connecting rod 32 rotates, it will simultaneously drive the first connecting rod 31 to rotate with the first pivot 34 In addition to rotating for the axis, the isolation cover 20 pivotally connected with the first connecting rod 31 can be rotated upwards with the hinge 12 as the axis; similarly, when the isolation cover of the signal isolation box 1 of the present utility model When the body 20 is intended to be closed from the isolation box 10, it is only necessary to actuate the pneumatic cylinder 33. When the telescopic rod 331 of the pneumatic cylinder 33 shrinks inwardly, the second connecting rod 32 and the linkage of the first connecting rod 31 , the isolation cover 20 rotates with the hinge 12 as the axis and closes the opening of the isolation box 10 downward tightly.

Furthermore, due to the setting of the cover opening mechanism 30, the isolation cover 20 in the utility model can be opened at an angle greater than or equal to more than 90 degrees corresponding to the opening 11 of the isolation box 10, which will facilitate the use Or place a larger test object inside the isolation box 10 for testing, without the trouble of placing the test object inside the isolation box 10 because the opening angle of the isolation cover 20 is too small.

The utility model mainly uses the setting of the cover opening mechanism, so that when the cover opening mechanism operates, the linkage and cooperation of the connecting rod group can be used to make the isolation cover corresponding to the isolation box to produce a larger opening angle. , in order to facilitate placing the test object inside the isolation box.

To sum up, it is only a preferred embodiment of the utility model, and is not intended to limit the utility model; all other equivalent modifications or replacements that do not deviate from the spirit disclosed in the utility model should be included in the within the scope of the claims of the application.
