[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-5As shown, this utility model provides a technical solution: a network filter anti-interference protective shell, including a mounting base 1 and an anti-interference protective shell body 2. A filter body 3 is fixedly mounted on the surface of the mounting base 1, and a mounting plate 4 is fixedly mounted on the side of the mounting base 1. Positioning holes 5 are formed on the surface of the mounting plate 4. A heat sink 6 is fixedly mounted on the lower surface of the mounting base 1. An embedding groove 7 is formed on the surface of the mounting base 1. A limiting frame 8 is fixedly mounted on the side of the mounting base 1. A limiting block 9 is slidably connected inside the limiting frame 8. A guide rod 10 is fixedly mounted inside the limiting frame 8, and a tension spring 11 is provided inside the limiting frame 8. The anti-interference protective shell body 2 has a limiting hole 12 on its side. The anti-interference protective shell body 2 is fitted and connected to the embedding groove 7. The limiting block 9 is slidably connected to the limiting hole 12 and the limiting block 9 is slidably connected to the guide rod 10. One end of the tension spring 11 is fixedly connected to the inner side of the limiting frame 8, and the other end of the tension spring 11 is fixedly connected to the side of the limiting block 9. The mounting base 1 is provided with a tension spring 13 inside. The mounting base 1 is slidably connected with a top block 14 inside. One end of the tension spring 13 is fixedly connected to the inner side of the mounting base 1, and the other end of the tension spring 13 is fixedly connected to the side of the top block 14.

[0024] In this embodiment, the anti-interference protective shell body 2 is fitted into the embedding groove 7 of the mounting base 1, facilitating the installation and removal of the protective shell. When maintenance or repair of the filter is required, first pull the limiting block 9 to slide it out of the limiting hole 12. At the same time, the tension spring 11 will be compressed, releasing the limiting of the anti-interference protective shell body 2. The anti-interference protective shell body 2 can then be easily removed from the embedding groove 7. The entire process is simple and quick, eliminating the need for traditional screw fixing and complex tools, significantly shortening the maintenance and repair time. To reduce time and labor costs, after installation, the tension spring 11 returns to its elasticity, pushing the limit block 9 back into the limit hole 12 to achieve limit fixation. During the disassembly of the anti-interference protective shell body 2, through the tension spring 13 and the top block 14 inside the mounting base 1, when the fixation of the anti-interference protective shell body 2 is released, the tension spring 13 will return from the compressed state, thereby causing the top block 14 to apply an upward pushing force to the bottom end of the anti-interference protective shell body 2, which makes it easier to remove the anti-interference protective shell body 2, thus improving the convenience of disassembly operation.

[0025] The working principle of this embodiment is as follows: During use, after the mounting base 1 is installed using the mounting plate 4, the filter body 3 is fixedly installed on the surface of the mounting base 1. Next, the anti-interference protective shell body 2 is inserted along the embedding groove 7 of the mounting base 1, ensuring a tight fit. At this time, the limiting block 9 in the limiting frame 8, under the action of the tension spring 11, slides along the guide rod 10 and inserts into the limiting hole 12 on the side of the anti-interference protective shell body 2, completing the fixing of the protective shell and ensuring its stable protection of the filter from interference. When the protective shell needs to be disassembled for filter maintenance or repair, the limiting block 9 is first manually pulled to overcome the elastic force of the tension spring 11 and slide out from the limiting hole 12 along the guide rod 10, releasing the limiting of the anti-interference protective shell body 2. Simultaneously, the inside of the mounting base 1 is under compression. The tension spring 13, in its reset state, pushes the connected top block 14 upward. The top block 14 applies an upward force to the bottom of the anti-interference protection shell body 2. Thus, under the combined action of the limit release and the upward force, the anti-interference protection shell body 2 can be easily removed from the embedding groove 7. The whole process is simple to operate and requires no complicated tools. After maintenance and repair, the anti-interference protection shell body 2 is re-embedded into the embedding groove 7. The limit block 9 automatically returns to its original position and inserts into the limit hole 12 under the action of the tension spring 11, completing the reinstallation of the protection shell and restoring the filter to its normal protected state. Thus, through the synergistic action of various components, the convenient installation and removal of the protection shell and the stable anti-interference protection function are realized, meeting the needs of network filters for efficient operation and convenient maintenance in complex electromagnetic environments.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
