In the following description, many specific details are set forth to provide a thorough understanding of the embodiments. However, it is obvious that, for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail so as not to unnecessarily obscure these embodiments. Additionally, all embodiments may be used in combination with each other.

[0027] Please refer to Figures 1 to 6 , the present utility model provides a technical solution:

[0028] Embodiment 1, a thin and light multi-channel filter cavity, the thin and light multi-channel filter cavity includes: a filter cavity main body 1.

[0029] Specifically, a mounting bracket 2 is fixedly connected to the center of each cavity of the filter cavity main body 1. One end of the mounting bracket 2 is rotatably connected to a lead screw 3. The mounting bracket 2 facilitates the rotational installation of the lead screw 3. Two mounting bases 4 symmetrically arranged with the lead screw 3 as the center are threadedly inserted into the side surface of the lead screw 3. The mounting base 4 contacts the filter cavity main body 1 and is slidably connected to the filter cavity main body 1. A plurality of positioning grooves 5 for inserting resonance rods are formed in the side surface of the mounting base 4. In this way, after rotating the mounting bracket 2 to slide the mounting base 4 out of the filter cavity main body 1, the corresponding resonance rod can be inserted into the positioning groove 5, and then by rotating the mounting bracket 2, the mounting base 4 can be slidably inserted into the filter cavity main body 1. A plurality of fixing components 6 corresponding to the positions of the positioning grooves 5 and used for fixing the resonance rods are arranged on the side surface of the mounting base 4. The resonance rod inserted into the positioning groove 5 will be fixed by the fixing component 6, making the connection between the resonance rod and the screw more stable. A plurality of screw holes 8 corresponding to the positions of the positioning grooves 5 are formed in one side of the filter cavity main body 1. The mounting base 4 entering the filter cavity main body 1 will make the resonance rod correspond to the screw holes 8, thereby making the connection between the screw and the resonance rod more convenient and fast.

[0030] To facilitate the sliding installation of the mounting base 4, a slider 9 is fixedly connected between the two mounting bases 4 of the present application. The lead screw 3 is threadedly inserted into the slider 9, and the slider 9 is slidably connected to the mounting bracket 2. When the lead screw 3 is rotated, it will drive the slider 9 to slide in the mounting bracket 2, thereby driving the two mounting bases 4 to slide synchronously. In this way, it is not only convenient for the sliding insertion of the mounting base 4, but also can make the mounting base 4 more stable after entering the filter cavity main body 1.

[0031] To facilitate the installation of the lead screw 3, a limit block 31 is fixedly connected to one side of the lead screw 3 of the present application. An installation groove 22 for rotatably installing the limit block 31 is provided on the side surface of the mounting bracket 2. Through the cooperation of the installation groove 22 and the limit block 31, the lead screw 3 can be well rotatably installed on the mounting bracket 2, and at the same time, the axial displacement of the lead screw 3 can be effectively avoided. A sliding groove 21 for slidably installing the slider 9 is provided at one end of the mounting bracket 2. As Figure 3 and Figure 4 shown, the sliding groove 21 can not only facilitate the sliding of the slider 9, but also facilitate the insertion of the lead screw 3, and can effectively prevent the slider 9 from rotating when being driven by the lead screw 3 to slide, thereby making the movement of the mounting base 4 more stable.

[0032] To facilitate the fixing component 6 to fix the resonant rod, a plurality of missing grooves 41 for installing the fixing component 6 are provided on the side surface of the mounting base 4 of the present application. The missing grooves 41 communicate with the positioning grooves 5, so that the fixing component 6 can better fix the resonant rod.

[0033] To better fix the resonant rod, the fixing component 6 of the present application includes a clamping plate 61 arranged in a "V" shape. The clamping plate 61 is located in the inner cavity of the missing groove 41 and is slidably connected to the mounting base 4. A spring 63 is fixedly connected between the fixing component 6 and the mounting base 4. Before the resonant rod is inserted into the positioning groove 5, first control the clamping plate 61 to slide away from the positioning groove 5, then insert the resonant rod into the positioning groove 5, and then release the restraint on the clamping plate 61. The clamping plate 61 in the free state will cooperate with the mounting base 4 under the action of the spring 63 to clamp the resonant rod in the positioning groove 5.

[0034] To facilitate the installation of the clamping plate 61, one end of the clamping plate 61 of the present application is fixedly connected with a guide rod 62. A plurality of mounting plates 7 corresponding to the positions of the missing grooves 41 are fixedly connected to one side of the mounting base 4. The guide rod 62 is slidably inserted into the mounting plate 7 and the spring 63 is located between the mounting plate 7 and the clamping plate 61. A jack 71 for slidably inserting the guide rod 62 is provided through one side of the mounting plate 7. A jack 71 for slidably inserting the guide rod 62 is provided through one side of the mounting plate 7. Through the sliding insertion of the guide rod 62 and the mounting plate 7, it is more convenient to control the displacement of the clamping plate 61.

[0035] To further improve the structure of the fixing component 6, one end of the guide rod 62 of the present application is fixedly connected with a baffle 64. The baffle 64 can more conveniently apply a pulling force to control the sliding of the clamping plate 61, and can also effectively limit the sliding of the guide rod 62 out of the mounting plate 7. A rubber pad 65 is fixedly connected to the side of the clamping plate 61 in contact with the resonant rod. The rubber pad 65 can further protect the resonant rod, and the rubber pad 65 can also increase the friction between the clamping plate 61 and the resonant rod, making the resonant rod fixed more stably.

[0036] In actual implementation, first rotate the screw rod 3 to control the sliding of the mounting base 4 out of the filter cavity body 1. Then, according to the corresponding positioning groove 5, control the sliding of the clamping plate 61 corresponding to the positioning groove 5 away from the positioning groove 5. At this time, insert the resonance rod into the positioning groove 5 correspondingly. Then loosen the baffle 64. At this time, the clamping plate 61 will slide under the action of the spring 63 and cooperate with the mounting base 4 to clamp and fix the resonance rod in the positioning groove 5. Then install the resonance rods in sequence. After all the resonance rods are installed, rotate the screw rod 3 to slide the mounting base 4 into the filter cavity body 1. At this time, the resonance rods in each positioning groove 5 will correspond to the multiple screw holes 8 on the filter cavity body 1. Then thread-insert the screws into the screw holes 8 and the resonance rods, and the resonance rods can be fixed on the filter cavity body 1, which is very convenient.

[0037] 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. The scope of the present invention is defined by the appended claims and their equivalents.
