[0021] In order to explain the content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0022] See also Figure 1 and Figure 2 The present invention discloses a cavity filter, including a filter cavity 1 and a flying rod piece fixing structure 2. A mounting position 10 is formed in the filter cavity 1, and two mounting ribs 11 are formed on both sides of the mounting position 10. The flying rod piece fixing structure 2 is vertically installed in the mounting position 10 and is firmly installed by clamping and cooperating with the two mounting ribs 11 through vertical sliding grooves 40 on its front and rear sides.

[0023] See also Figures 2 to 4 The flying rod piece fixing structure 2 includes a flying rod piece 20 and two flying rod piece fixing seats 30. The rear sides of the two flying rod piece fixing seats 30 are respectively formed with a docking surface 31 and a slot 32 for installing the flying rod piece 20. After the two flying rod piece fixing seats 30 are docked with each other, their slots 32 are engaged with each other, and the flying rod piece 20 is fixed in the slot 32 of the two flying rod piece fixing seats 30. In order to facilitate production and reduce mold opening costs, in a specific example of the present invention, the two flying rod piece fixing seats 30 have the same structure, but not limited to this. In order to quickly dock, the docking surface 31 of the two flying rod piece fixing seats 30 is provided with a concave-convex matching structure, but not limited to this.

[0024] See also Figures 1 to 4 The fly rod piece fixing seat 30 includes a base 33 and two side plates 34 connected to the left and right sides of the base 33. A notch 35 is formed on the front side of the base 33. The base 33 is respectively connected to a left column 36 and a right column 37 spaced from the two side plates 34 on the left and right sides of the notch 35. The base 33 is connected to a rear column 38 located between the left column 36 and the right column 37 on the rear side of the notch 35. The top ends of the two side plates 34, the left column 36, the right column 37 and the rear column 38 are connected to a top plate 39. A vertical slide groove 40 corresponding to the notch 35 is formed between the column 36, the right column 37 and the rear column 38 for slidingly cooperating with the mounting rib 11 of the filter cavity 1. The left column 36, the right column 37 and the rear column 38 are respectively formed with vertical sliding surfaces 41. At least one group of protrusions 42 located at the same height are convexly provided on the vertical sliding surfaces 41 of the left column 36, the right column 37 and the rear column 38. When the mounting rib 11 slides into the vertical slide groove 40, at least one group of protrusions 42 is elastically squeezed outward by the mounting rib 11.

[0025] The flying rod piece fixing seat 30 of the present invention uses the base 33, the two side plates 34 and the top plate 39 as the overall frame to ensure the stability of the overall structure, and defines a vertical slide groove 40 that cooperates with the mounting rib 11 of the filter cavity 1 through the left column 36, the right column 37 and the rear column 38, and at least one group of protrusions 42 located at the same height are convexly provided on the vertical sliding surfaces 41 of the left column 36, the right column 37 and the rear column 38. In this way, when the flying rod piece fixing structure 2 composed of the two flying rod piece fixing seats 30 and the flying rod is assembled to the mounting position 10 of the filter cavity 1, at least one group of protrusions 42 is slid The mounting rib 11 inserted into the vertical slide groove 40 is elastically squeezed outward; thereby, it can largely avoid the situation that the installation is difficult or even fails due to the width of the vertical slide groove 40 being too small relative to the mounting rib 11, or the situation that the vertical slide groove 40 is too large relative to the mounting rib 11, causing shaking after installation. At the same time, it can also largely avoid the situation that the installation is difficult or even fails due to the size of the front-to-back direction of the flying rod piece fixing structure 2 being too large, or the situation that the flying rod piece fixing structure 2 is too small in the front-to-back direction. The size causes shaking after installation. Moreover, the present invention defines the vertical slide groove 40 by the left column 36, the right column 37 and the rear column 38, and at the same time, a convex portion 42 that can be elastically squeezed is provided on the vertical sliding surface 41 of the left column 36, the right column 37 and the rear column 38, thereby greatly enhancing the combination stability of the flying rod piece fixing structure 2 and the two mounting ribs 11, which is beneficial to ensure the working reliability of the cavity filter.

[0026] In some embodiments, the convex portion 42 includes a vertical surface 421 and an upslope surface 422 and a downslope surface 423 respectively connected to the upper and lower ends of the vertical surface 421, and the upslope surface 422 and the downslope surface 423 are used to transitionally connect the vertical sliding surface 41 and the vertical surface 421. This design facilitates the sliding installation of the mounting rib 11 to the vertical sliding groove 40 and the stable matching of the mounting rib 11 and the convex portion 42.

[0027] In some embodiments, a groove 43 corresponding to the convex portion 42 is formed on the side of the left column 36 and the right column 37 opposite to the vertical sliding surface 41. Through this design, the elastic deformation of the corresponding convex portion 42 when pressed can be further increased, which is conducive to the fly bar piece fixing structure 2 being more firmly clamped and combined with the two mounting ribs 11, and the tolerance requirements can also be further relaxed.

[0028] In some embodiments, the notch 35 is in a trumpet shape to guide the mounting rib 11 to slide into the vertical slide groove 40 , thereby facilitating the rapid assembly of the fly bar piece fixing structure 2 .

[0029] In some embodiments, the middle parts of the two side plates 34, the left column 36, the right column 37 and the rear column 38 are connected with reinforcing plates 44, and the reinforcing plates 44 separate the left column 36, the right column 37 and the rear column 38 into an upper column portion S and a lower column portion X, and the upper column portion S and the lower column portion X are respectively formed with a group of protrusions 42. The provision of the reinforcing plates 44 can increase the strength of the overall structure, which is conducive to the fly rod piece fixing structure 2 being more firmly clamped and combined with the two mounting ribs 11.

[0030] As a preferred embodiment, the rear end face of the reinforcing plate 44 is flush with the rear end faces of the base 33 and the two side plates 34, the rear end faces of the base 33, the two side plates 34 and the reinforcing plate 44 form a docking surface 31, the rear end faces of the two side plates 34 are formed with two corresponding first card grooves 321, and the card groove 32 includes two first card grooves 321. Through this design, it is easy to achieve reliable docking between the two fly rod piece fixing seats 30 and stable installation of the fly rod piece 20.

[0031] Specifically, a middle plate 45 located between the two side plates 34 is connected between the reinforcing plate 44 and the base 33. The middle plate 45 is opposite to and connected to the rear column 38. The rear end surface of the middle plate 45 is flush with the rear end surfaces of the two side plates 34 and is formed with a second card slot 322 corresponding to the two first card slots 321. The card slot 32 also includes a second card slot 322. Through this design, the strength of the overall structure can be further increased, and a more stable installation of the flying rod piece 20 can also be achieved.

[0032] In some embodiments, the front side of the top of the two side plates 34 is connected to the top plate 39, and the rear side of the top of the two side plates 34 extends upward to form two connecting plates 46. The front side of the top of the two connecting plates 46 is connected to a crossbeam 47 located above the top plate 39, and the middle part of the crossbeam 47 is convexly provided with a protrusion 48, and the crossbeam 47 is staggered with the left column 36 and the right column 37 in the front-to-back direction. By forming the crossbeam 47 and the protrusion 48, the difficulty or even failure of installation caused by the large vertical tolerance and the shaking phenomenon caused by the small tolerance after installation can be effectively reduced, and reliable contact with the filter cover (not shown) can be achieved. Moreover, since the crossbeam 47 is staggered with the left column 36 and the right column 37 in the front-to-back direction, when it is pressed downward by the filter cover, it will basically not affect the cooperation between the left column 36 and the right column 37 and the mounting rib 11, which is conducive to the stable installation of the flying rod piece fixing structure 2.

[0033] The above disclosure is only a preferred embodiment of the present invention, which is to facilitate the understanding and implementation of the present invention by those skilled in the art. It certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
