[0006] To achieve the above purpose, the utility model provides the following technical solution: A filter resonator rod mounting assembly, the filter resonator rod mounting assembly includes:

[0007] A filter main body, a plurality of screw holes are opened on the side of the filter main body, one end of the screw hole is threadedly inserted with a screw, a plurality of fixing plates with corresponding screw positions are fixedly connected to both sides of the filter main body, a "V"-shaped limiting plate is slidably connected to one side of the fixing plate, a first spring is fixedly connected between the limiting plate and the fixing plate, a fixing component for restricting the sliding of the limiting plate is arranged on the side of the fixing plate, a plurality of inclined side baffles are fixedly connected to one end of the limiting plate, and a rubber pad is fixedly connected to the side of the limiting plate in contact with the screw.

[0024] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0025] Embodiment 1, a filter resonator rod mounting assembly, the filter resonator rod mounting assembly includes: a filter main body 1.

[0026] Specifically, a plurality of screw holes 11 are formed in the side surface of the filter body 1. One end of each screw hole 11 is threadedly inserted with a screw 2. The screw holes 11 facilitate the threaded insertion of the screws 2. The screws 2 can fix the resonant rod inside the filter body 1. A plurality of fixing plates 5 corresponding to the positions of the screws 2 are fixedly connected to both sides of the filter body 1. One side of the fixing plate 5 is slidably connected with a limiting plate 3 arranged in a "V" shape. The fixing plate 5 facilitates the sliding installation of the limiting plate 3. A first spring 4 is fixedly connected between the limiting plate 3 and the fixing plate 5. A fixing component for restricting the sliding of the limiting plate 3 is arranged on the side surface of the fixing plate 5. When installing the screw 2, it is necessary to slide the limiting plate 3 away from the screw 2. At this time, the limiting plate 3 is fixed by using the fixing component, and the installation space of the screw 2 can be avoided. After the screw 2 is installed, the restraint of the limiting plate 3 is released, and the limiting plate 3 in the free state will slide and contact the screw 2 under the action of the first spring 4. One end of the limiting plate 3 is fixedly connected with a plurality of inclined side baffles 6. The side baffles 6 can further restrict the screw 2 and further prevent the screw 2 from sliding out of the screw hole 11. A rubber pad 7 is fixedly connected to the side of the limiting plate 3 in contact with the screw 2. The rubber pad 7 can further increase the friction between the limiting plate 3 and the screw 2, making the installation of the screw 2 more stable. At the same time, the rubber pad 7 can also provide a certain protection for the screw 2.

[0027] To facilitate the sliding installation of the limiting plate 3, one end of the limiting plate 3 of the present application is fixedly connected with a guide rod 31. A positioning hole 51 for the sliding insertion of the guide rod 31 is formed through one side of the fixing plate 5. Through the sliding insertion of the guide rod 31 and the positioning hole 51, the limiting plate 3 can be well slidably installed on the fixing plate 5. One end of the guide rod 31 is fixedly connected with a limiting block 32. The first spring 4 is located between the limiting block 32 and the fixing plate 5. The limiting block 32 can first prevent the guide rod 31 from sliding out of the fixing plate 5, and second, it can make the first spring 4 better installed between the limiting plate 3 and the fixing plate 5. At the same time, the limiting block 32 can also facilitate the application of a pulling force to control the sliding of the limiting plate 3.

[0028] To further stabilize the limiting plate 3, a first slider 34 is fixedly connected to one side of the guide rod 31 of the present application. A sliding groove 12 for the sliding of the first slider 34 is formed in one side of the filter body 1. Through the sliding connection of the first slider 34 and the sliding groove 12, the sliding track of the limiting plate 3 can be further restricted, making the limiting plate 3 more stable.

[0029] To effectively limit the sliding of the limit plate 3, the fixing component of the present application includes a limit rod 8. The limit rod 8 is located on one side of the fixing plate 5 and is slidably connected to the fixing plate 5. After the limit rod 8 slides, it is inserted into the insertion hole 33. The insertion hole 33 is opened on one side of the guide rod 31 and there are two of them. After the limit plate 3 and the guide rod 31 slide away from the screw 2, the limit rod 8 is slidably inserted into the insertion hole 33 close to the limit plate 3, thereby restricting the continuous sliding of the limit plate 3. After the limit plate 3 is reset, the limit rod 8 is slidably inserted into the insertion hole 33 close to the end of the fixing plate 5, thereby further restricting the limit plate 3 from shaking under the influence of vibration.

[0030] To facilitate the installation of the limit rod 8, one end of the limit rod 8 of the present application is fixedly connected with a second slider 81. A plug hole 82 is opened on one side of the second slider 81. One end of the fixing plate 5 is fixedly connected with a shaft rod 52 that is inserted into the plug hole 82 of the second slider 81, which can well slidably install the limit rod 8 on the fixing plate 5.

[0031] To further stabilize the limit rod 8, one end of the shaft rod 52 of the present application is fixedly connected with a connecting plate 53. The connecting plate 53 can limit the limit rod 8 from sliding out of the shaft rod 52. A second spring 9 is fixedly connected between the connecting plate 53 and the second slider 81. The second spring 9 can make the limit rod 8 more stably inserted into the insertion hole 33.

[0032] During actual implementation, first, the limit plate 3 and the guide rod 31 are slid away from the screw 2. Then, the limit rod 8 is slidably inserted into the insertion hole 33 close to the limit plate 3. Then, the screw 2 is threadedly inserted into the screw hole 11 and the resonant rod. After the screw 2 is fixed, the limit rod 8 is slid away from the guide rod 31. At this time, the first spring 4 will pull the limit block 32 to slide, thereby promoting the limit plate 3 to slide and contact the screw 2. Then, with the cooperation of the rubber pad 7, the friction force is used to limit the rotation of the screw 2 under the influence of vibration, and the side baffle 6 can further limit the upward sliding of the screw 2. After the side baffle 6 is in place, the limit rod 8 will also slide and be inserted into the insertion hole 33 close to the fixing plate 5 under the action of the second spring 9, further preventing the limit plate 3 from shaking and displacing under the influence of vibration. In this way, the screw 2 can be stably installed on the filter body 1, thereby making the installation of the resonant rod more stable.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
