Description

Technical Field

[0001] The utility model relates to the field of filter maintenance, in particular to a maintenance device for broadband microwave bandpass filters. Background Art

[0002] A broadband microwave bandpass filter is an electronic component used in wireless communication systems. It allows signals within a certain frequency range to pass while blocking signals of other frequencies. This filter is essential for ensuring signal clarity and preventing out-of-band interference. During use, the filter may fail due to aging, physical damage or electromagnetic interference and require maintenance. Therefore, a maintenance device for broadband microwave bandpass filters is needed.

[0003] After searching, a filter that is easy to repair with announcement number CN211183912U includes a filter body, a mounting plate is provided at the bottom of the filter body, mounting screws are provided on the inner wall of the mounting plate, a block is fixedly connected to the upper surface of the mounting plate, the block is located between the filter body and the mounting screws, and a spring is fixedly connected to the upper surface of the baffle. When repairing the filter body, the utility model pulls and rotates the clamping column to separate the clamping column from the clamping block. At this time, the filter body can be removed from the mounting plate. After repair, the filter body is placed on the mounting plate, and the positioning block is inserted into the positioning groove. Then, the clamping column is pulled and rotated so that the clamping column is stuck in the clamping groove. At this time, the filter body can be installed on the mounting plate, which makes it easy for users to disassemble and assemble the filter body, making it easier to repair the filter body.

[0004] Based on the above patent, by setting a mounting plate, a stopper, a spring, a support block, a clamping column, a clamping block, a clamping groove, a positioning groove and a positioning block, when the filter body needs to be repaired, the clamping column is pulled and rotated to separate the clamping column from the clamping block. At this time, the filter body can be removed from the mounting plate. After maintenance, the filter body is placed on the mounting plate, and the positioning block is inserted into the positioning groove. Through the cooperation of the positioning groove and the positioning block, the filter body cannot move forward and backward. Then the clamping column is pulled and rotated to make the clamping column stuck in the clamping groove. At this time, the filter body can be installed on the mounting plate, which is convenient for the user to disassemble and assemble the filter body and make the filter body The filter body is relatively easy to maintain, and the supporting block and the sliding column are connected together by a connecting ring, and then the supporting block is limited by a limiting block to prevent excessive pulling of the card column, which makes the spring unable to recover, and then makes the card column unable to be stuck in the slot, so that the filter body cannot be fixed on the mounting plate. At the same time, through the cooperation of the rotating shaft and the bearing, the sliding rod can rotate freely around the rotating shaft as the center, and thus does not affect the user to remove the card column from the slot. However, the spring will have mechanical wear during use, and its effectiveness will become worse and worse after repeated use, and it needs to be replaced regularly. In this regard, in response to this technical problem, this application proposes a maintenance device for broadband microwave bandpass filters. Utility Model Content
