[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 Figures 1 to 4The present invention discloses a flying rod fixing seat 100, which is in the shape of a rectangular parallelepiped as a whole. A flying rod positioning hole 1 and a lower end opening 2 that penetrate front and back are formed at the lower part of the flying rod fixing seat 100. The upper end of the lower end opening 2 is connected to the flying rod positioning hole 1, and the lower end of the lower end opening 2 penetrates downward. The left and right sides of the flying rod fixing seat 100 are respectively provided with vertically penetrating mounting grooves 3. The upper part of the flying rod fixing seat 100 is provided with a groove 4 that extends vertically and penetrates upward. The cross-section of the groove 4 is rectangular. The front and rear side walls of the groove 4 are respectively formed with grooves 5 that penetrate the flying rod fixing seat 100 outwards. The left and right sides of the groove 4 are respectively close to the two mounting grooves 3. The flying rod fixing seat 100 is respectively formed with two elastic beams 6 on the upper sides of the two grooves 5, and a protrusion 61 is protruded upward in the middle of the elastic beam 6.

[0023] The upper part of the flying rod fixing seat 100 of the present invention is provided with a rectangular groove 4 extending vertically and penetrating upward, and the front and rear side walls of the groove 4 are respectively formed with grooves 5 penetrating outwardly through the flying rod fixing seat 100, and the left and right sides of the groove 4 are respectively close to the two mounting slots 3, so that when the tolerance of the flying rod fixing seat 100 relative to the mounting position 201 in the cavity 200 in the left and right directions is too large, it can be elastically squeezed and deformed inward by the mounting ribs 202, which can largely avoid the difficulty in installing the flying rod fixing seat 100 due to the excessively large tolerance in the left and right directions, and even cause the phenomenon of failure in the installation of the flying rod fixing seat 100, and at the same time, it can also effectively prevent the occurrence of the phenomenon of too small processing tolerance caused by the fear of too large tolerance, reduce the shaking of the flying rod fixing seat 100 after installation, and even cause the phenomenon of failure due to poor indicators; moreover, by means of the rectangular frame design of the upper part of the flying rod fixing seat 100, the structural strength of the flying rod fixing seat 100 can also be guaranteed under the premise of ensuring its elastic deformation. In addition, due to the formation of the elastic beam 6 and the protrusion 61, the difficulty or even failure of installation caused by large vertical tolerance and the shaking after installation caused by small tolerance can be effectively reduced, and reliable contact with the filter cover (not shown) can be achieved. In addition, since the groove 4 and the elastic beam 6 are formed on the side wall different from the mounting slot 3, the deformation of the mounting slot 3 caused by the same side as the mounting slot 3 can be effectively avoided when the filter cover is excessively squeezed downward, and the stable combination of the mounting slot 3 and the mounting rib 202 can be effectively guaranteed.

[0024] In some embodiments, the slots 5 are formed at the upper portions of the front and rear side walls of the groove 4 , thereby avoiding damage to the strength of the fly rod fixing seat 100 due to the excessive vertical length of the groove 4 .

[0025] In some embodiments, the slot 5 is rectangular in shape, so as to facilitate the formation of the elastic beam 6 on the upper side thereof.

[0026] In some embodiments, the width of the groove 4 in the left-right direction is at least equal to the width of the widest part of the fly rod positioning hole 1. This design is conducive to the fly rod fixing seat 100 being elastically squeezed in the left-right direction to generate deformation.

[0027] In some embodiments, a connecting beam 7 is formed between the groove 4 and the flying rod positioning hole 1, and the vertical length of the groove 4 is much larger than the vertical length of the connecting beam 7, which is conducive to the flying rod fixing seat 100 being elastically squeezed and deformed in the left and right directions.

[0028] As a preferred embodiment, the vertical length of the flying rod positioning hole 1 at the middle position is greater than the vertical length of the connecting beam 7 at the middle position, so as to facilitate the flying rod fixing seat 100 to be elastically squeezed and deformed in the left and right directions.

[0029] In some embodiments, the width of the lower opening 2 is at least equal to the widest part of the fly rod positioning hole 1, and the two side walls of the connection between the lower opening 2 and the fly rod positioning hole 1 are respectively provided with stopper portions 8 protruding inwardly for stopping the fly rod 300. This design facilitates the fly rod fixing seat 100 to be elastically squeezed and deformed in the left and right directions.

[0030] In some embodiments, the mounting slot 3 includes a lower slot 31 and an upper slot 32, the width of the lower slot 31 is greater than the width of the upper slot 32, and the top ends of the two side walls of the lower slot 31 transition inwardly to the bottom ends of the two side walls of the upper slot 32. The design of the slightly wider lower slot 31 facilitates assembly with the mounting rib 202, and the interference fit between the slightly narrow upper slot 32 and the mounting rib 202 ensures that the fly rod fixing seat 100 is securely installed.

[0031] As a preferred embodiment, the bottom end of the lower slot 31 is connected with a guide slot 33 opened outward, so that the flying rod fixing seat 100 can be quickly assembled.

[0032] See also Figures 1 to 4 The present invention also discloses a cavity filter, including a cavity 200, a flying rod fixing seat 100 and a flying rod 300, a mounting position 201 is formed in the cavity 200, two mounting ribs 202 are formed on both sides of the mounting position 201, the flying rod fixing seat 100 is as described in the above embodiment, the flying rod 300 is installed in the flying rod positioning hole 1, the flying rod fixing seat 100 is vertically installed in the mounting position 201, and the mounting ribs 202 are clamped in the mounting slot 3.

[0033] The present invention provides a rectangular groove 4 extending vertically and penetrating upwardly on the upper part of the flying rod fixing seat 100, and the front and rear side walls of the groove 4 are respectively formed with grooves 5 penetrating outwardly through the flying rod fixing seat 100, and the left and right sides of the groove 4 are respectively close to the two mounting slots 3, so that when the tolerance of the flying rod fixing seat 100 relative to the mounting position 201 in the cavity 200 in the left and right directions is too large, it can be elastically squeezed and deformed inwardly by the mounting ribs 202, which can largely avoid the difficulty in installing the flying rod fixing seat 100 due to the excessively large tolerance in the left and right directions, and even cause the phenomenon of failure in installing the flying rod fixing seat 100, and at the same time, it can also effectively prevent the occurrence of the phenomenon of too small processing tolerance caused by the fear of too large tolerance, reduce the shaking of the flying rod fixing seat 100 after installation, and even cause the phenomenon of failure due to poor indicators; moreover, by means of the rectangular frame design of the upper part of the flying rod fixing seat 100, the structural strength of the flying rod fixing seat 100 can also be guaranteed under the premise of ensuring its elastic deformation. In addition, due to the formation of the elastic beam 6 and the protrusion 61, the difficulty or even failure of installation caused by large vertical tolerance and the shaking after installation caused by small tolerance can be effectively reduced. In addition, since the groove 4 and the elastic beam 6 are formed on the side wall different from the mounting slot 3, the deformation of the mounting slot 3 caused by being arranged on the same side as the mounting slot 3 can be effectively avoided when the filter cover is excessively squeezed downward, and the stable combination of the mounting slot 3 and the mounting rib 202 can be effectively guaranteed.

[0034] 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.
