Filter easy to assemble

Abstract

The utility model relates to a filter easy to assemble, which comprises a bottom shell, two resonant cavities are arranged in the bottom shell, resonant partition plates are sequentially connected to the inner side walls of the two resonant cavities in a staggered manner, and positioning insertion holes are formed in the four corners of the inner cavity walls of the resonant cavities and the two ends of the resonant partition plates. And a resonator is fixedly mounted at a position between every two adjacent resonance partition plates. The utility model relates to the technical field of filtering devices. According to the filter easy to assemble, when the sealing cover is buckled to the upper end of the bottom shell, the U-shaped lock catches slide into the two sliding grooves in the same side of the bottom shell and the sealing cover at the same time, and then the effect that the sealing cover is fixedly installed on the top of the bottom shell is achieved; the U-shaped lock catch and the sliding groove form a dovetail joint shape, so that the connection stability of the U-shaped lock catch and the sliding groove is improved, the purpose of preventing the U-shaped lock catch from loosening is achieved, and the stability of the filter is effectively improved.
