Description

Compact range feed source mounting structure Technical Field The utility model relates to the technical field of feed source installation, in particular to a compact field feed source installation structure. Background In the field of modern electromagnetic measurement, the compact range can simulate the characteristic of a far-field test environment in a limited space, so that the compact range becomes a key facility for researching antenna performance test, radar scattering cross section measurement and the like, and the compact range emits spherical waves through a feed source and converts the spherical waves into plane waves through a reflecting surface, so that a stable electromagnetic environment is provided for the test, and the accuracy and reliability of a test result are directly determined by the installation accuracy of the feed source. At present, a feed source waveguide is usually fixed by adopting a bolt fastening type clamp, namely, after the waveguide is clamped by adopting the clamp matched with the waveguide, the waveguide is clamped and installed by screwing the bolt to fix the clamp, when the axial position of the waveguide is adjusted by adjusting the focus of the feed source, the clamp is required to be loosened by screwing the bolt, and then the waveguide is displaced, however, the existing clamp is better in clamping stability, a plurality of bolts are required to be screwed one by adopting a bolt fastening mode, the bolts are required to be loosened sequentially during the installation, the operation is tedious and time-consuming, particularly, the operation efficiency is greatly influenced under the scene of frequently replacing or adjusting the feed source, and during the direct operation, the waveguide is easy to scratch and collide with surrounding parts, and the surface scratch and deformation are possibly caused, so that the performance and the service life of the waveguide are influenced. Based on the above situation, we propose a compact feed installation structure to solve the above problems. Disclosure of utility model The utility model provides a compact feed source installation structure which aims to solve the problems in the prior art. The technical problems solved by the utility model are realized by adopting the following technical scheme: The utility model provides a compact range feed source mounting structure, includes mounting base, clamping piece and retaining member, mounting base is at least one end open-ended tubular structure, and its inner wall is provided with along axially extending's dovetailed guide rail groove, the clamping piece is used for carrying out the centre gripping to the feed source main part fixedly, just the clamping piece is through dovetailed guide rail groove sliding connection in mounting base's inside for drive the feed source main part and carry out axial position adjustment, the clamping piece is used for carrying out the centre gripping fixedly to the feed source main part, just the clamping piece is through dovetailed guide rail groove sliding connection in mounting base's inside for drive the feed source main part and carry out axial position adjustment. Preferably, the clamping piece comprises a connecting member and two clamping jaws movably connected with the connecting member, the two clamping jaws are oppositely arranged with the central line of the connecting member, the lower ends of the two clamping jaws are provided with extension parts, and the two extension parts are detachably connected through bolts. Preferably, the locking piece comprises a locking rod connected to the upper end of the connecting member in a threaded manner and a locking plate arranged on the locking rod, and when the locking rod drives the locking plate to abut against the mounting base, the clamping piece is fixed.
