Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter packaging structure. Background Art

[0002] A filter is an electronic component or circuit that is used to selectively pass or block signals within a specific frequency range in a circuit. Its main function is to process signals based on their frequency characteristics. Common applications include signal processing, communications, audio processing, power transmission, and other fields. When replacing existing filters, it is necessary to remove the lines connecting the two sides of the filter, and then remove the fixing screws at the bottom of the packaging structure. When removing the fixing screws, it is necessary to open the lines near the filter base for disassembly. The process is relatively complicated, and when the device is affected by vibration for a long time, metal fatigue is prone to occur between the filter and the filter wing plate, and there is a risk of the filter wing plate breaking.

[0003] The implementation of the utility model aims to provide a filter packaging structure to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art mentioned in the background technology and to propose a filter packaging structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A filter packaging structure comprises a mounting base, a rubber pressing plate and a spring telescopic rod B, wherein a rubber pressing plate is provided on the inner side of the mounting base, and a spring telescopic rod B is provided on the upper end of the rubber pressing plate, a striped friction pad is provided on the bottom of the rubber pressing plate, a pressing plate control plate is provided on one side of the rubber pressing plate, a rubber pad is provided on the lower end of the rubber pressing plate, and an air bag is provided on the bottom of the rubber pad, and a spring telescopic rod A is provided on the outer side of the air bag.

[0007] Preferably, a pressure plate connecting rod is provided on the side of the rubber pressure plate, and a connecting sleeve is provided on the other side of the pressure plate connecting rod, and a sliding rod is slidably connected to the inner side of the connecting sleeve.

[0008] Preferably, a filter is provided on the inner side of the mounting base, and filter wing plates are provided on the left and right sides of the bottom of the filter, and fixing plates are fixedly connected to the left and right sides of the bottom of the mounting base.

[0009] Preferably, an airbag cushion is provided at the bottom of the filter, and an air pipe is connected through the side of the airbag cushion, and the other side of the air pipe is connected through the airbag.

[0010] Preferably, a rubber pad is provided at the bottom of the airbag cushion, and before the filter is installed, the level of the airbag cushion is lower than the rubber pad.

[0011] Preferably, rectangular grooves are provided on the left and right sides of the mounting base, and an inflation tube is provided in the groove, and the inflation tube passes through the mounting base and is connected with the airbag.

[0012] Preferably, slide bars are fixedly mounted on both left and right sides of the inner side of the mounting base, and three slide bars equidistantly distributed are respectively arranged on the left and right sides, and a connecting sleeve and a pressure plate connecting rod are arranged on the outer side of each slide bar.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, by arranging a rubber pressure plate and a spring telescopic rod B, when the staff needs to replace the filter, they can pull the pressure plate control plate upward by hand, so that the pressure plate control plate drives the rubber pressure plate to move upward, so that the rubber pressure plate is separated from the surface of the filter wing plate, and then the filter is moved forward, and then the new filter is inserted between the rubber pressure plate and the rubber pad. After the filter is inserted, the pressure plate control plate is loosened, so that the spring telescopic rod B drives the rubber pressure plate to rebound downward and press the filter wing plate to complete the installation, so that the device does not need to remove the fixing screws at the bottom of the packaging structure when replacing the filter, which simplifies the filter replacement process.

[0015] 2. By setting the spring telescopic rod A and the spring telescopic rod B, when the filter is affected by external vibrations, the filter wing plate will be pressed down during the shaking process, which will cause the rubber pad to press down and touch the bottom airbag. After the airbag is stressed, the air will be discharged into the airbag cushion through the air pipe. Then the airbag cushion bulges and fits the bottom of the filter, so that the filter and the filter wing plate can vibrate with a smaller amplitude and the same frequency, reducing the risk of metal fatigue between the filter and the filter wing plate causing the filter wing plate to break.
