Problems solved by technology

[0002] The current laboratory electromagnetic field test devices are basically manually adjusted, including the horizontal attitude, pitch angle, etc. of the antenna, which brings a certain degree of workload to the antenna test work. At the same time, the manual adjustment links increase, and the test accuracy of the antenna will decrease accordingly.

Abstract

The invention discloses an adaptive fixing device for a field strength antenna. The device comprises an antenna bracket, a counter weight and external testing rotatable parts, wherein rotating shafts are arranged on the two sides of the antenna bracket; the axes of the rotating shafts pass through the balance center of the whole antenna bracket; bearings are sleeved outside the rotating shafts; the counter weight is fixed on the lower surface of the antenna; the central axis of the counter weight vertically passes through the balance center of the antenna bracket; rotating holes are formed in the external testing rotatable parts; the bearings outside the rotating shafts are embedded into and assembled on the inner sides of the rotating holes in a tight fit mode; bearing fixing covers are arranged on the outer sides of the rotating holes; and the rotating shafts are fixedly connected with the bearing fixing covers. By the device, the attitude level can be automatically adjusted, the step of manually adjusting the attitude level is eliminated, the aim of keeping the attitude level after the external testing rotatable parts adaptively rotate in a vertical plane at any angle is fulfilled, and testing accuracy and working efficiency are improved.

Description

technical field [0001] The invention relates to an electromagnetic field antenna test frame, in particular to an adaptive fixing device for a field strength antenna. Background technique [0002] The current laboratory electromagnetic field test devices are basically manually adjusted, including the horizontal attitude and pitch angle of the antenna, etc., which brings a certain degree of workload to the antenna test work. At the same time, the number of manual adjustment links increases, and the test accuracy of the antenna will decrease accordingly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a field strength antenna adaptive fixing device; the fixing device can automatically adjust the attitude level of the entire test device, reducing the manual adjustment of the attitude level, and reaching the vertical plane of the self-adaptive external test device The purpose of keeping the attitude level after rotati...
