Embodiment 1

[0031] refer to figure 1 , a stripline device, comprising a stripline 2, one end fixedly connected to the stripline 2 and a plurality of hoisting ropes 3 whose other end passes through the top shielding plate 1 of the anechoic chamber, and one end of the centrally fixed hoisting ropes 3 away from the stripline 2 The walking trolley 4 and the track 5 for walking the trolley 4. Stripline 2 remains horizontal.

[0032] In order to prevent external interference, the anechoic chamber is closed by a shielding plate 1 , and a wave-absorbing material 10 is fixed inside the shielding plate 1 . The stripline 2 is hidden in the absorbing material 10 when it rises to the limit. The hoisting rope 3 adopts non-metallic rope, preferably a skydiving rope, which has low elasticity and high strength, and its quantity has 12 in total, which are evenly fixed on the strip line 2. The hoisting rope 3 is in a tensioned state, and the other end away from the strip line 2 is concentrated and fixed ...

Abstract

The invention relates to a stripline device, which includes a stripline, a plurality of hoisting ropes whose one end is fixedly connected to the stripline and whose other end passes through the top shielding plate of an anechoic chamber, and a centrally fixed hoisting rope at one end away from the stripline The trolley and the track for the trolley to walk on, the strip line is kept horizontal. The invention has the characteristic of more convenient adjustment of the height of the strip line.

Description

technical field [0001] The invention relates to an immunity test device, in particular to a strip line device. Background technique [0002] In the anechoic chamber, when the immunity test of the whole vehicle is carried out, the test strip line needs to be hoisted to the top of the anechoic chamber. The stripline is usually hidden in the top absorbing material of the anechoic chamber, and the height of the stripline is adjusted according to the size of the car during use. [0003] The traditional design adopts the way of hand-operated pulley, and the waveguide on the top of the anechoic chamber passes through the non-metallic rope to realize hoisting and height adjustment, which is inconvenient to use. Contents of the invention [0004] The object of the present invention is to provide a stripline device which is characterized by ease of use. [0005] The above object of the present invention is achieved through the following technical solutions: a stripline device, com...
