[0003] In conventional RF modulation structures, the screw and nut are separate components. The nut has internal threads, and the screw has external threads. The screw extends into and is suspended from the cover plate by the engagement of these threads. Frequency is adjusted by varying the depth to which the screw extends beneath the cover plate. However, because the cover plate has a through-hole through which the screw passes, when the screw and nut are separate components with internal threads and external threads, debris generated by the helical engagement of the internal and external threads easily falls into the cavity beneath the cover plate through the through-hole. Therefore, in conventional RF modulation structures, the long-term accumulation of debris within the cavity can affect the frequency modulation performance. Summary of the Invention

The cover plate 2 includes a base plate portion 21 and a column portion 22 convex upwards from the substrate portion 21 , which has a through hole 20 running from top to bottom through the column portion 22 and the substrate portion 21 in the vertical direction, and the column portion 22 is provided with an external thread 220 spirally enclosed in the vertical direction. The preceding adjusting screw portion 11 is provided through the preceding through hole 20 and is capable of adjusting its installation depth relative to the preceding cover plate 2 by relying on a fit between the preceding internal thread 120 and the preceding external thread 220 . Since the invention resorts to disposition of the internal thread 120 on the cap cover portion 12 of the preceding adjusting screw 1 and the external thread 220 disposed on the cylinder portion 22 of the preceding cover plate 2 In combination, its installation depth relative to the cover plate 2 is adjusted to adjust the frequency. At the same time, the debris generated by the helical fit between the internal thread 120 and the external thread 220 is blocked by the column part 22 of the aforementioned cover plate 2, avoiding the debris falling under the cover plate 2 through the aforementioned through hole 20, improving intermodulation and further optimizing the frequency modulation effect.

[0021] Please refer specifically to Figs.

[0022] 3, 4, 6 and 7, the cap cover portion 12 includes a brim portion 121 extending in the aforementioned vertical direction, the aforementioned cap brim portion 121 surrounds outside the aforementioned tuning screw portion 11, and the aforesaid internal thread 120 is disposed on and facing the aforementioned tuning screw portion 11 . It is easy to imagine that the so-called cap cap portion 12 is similar to a bottle cap, the inner wall surface 1211 of the aforementioned cap is circular, the internal thread 120 spirally loops on the vertically extended inner wall surface 1211 of the cap, the internal thread 120 faces the aforementioned adjusting screw portion 11 to facilitate screwing with the external thread portion 22 provided on the spiral cap plate 2 2 .

[0023] Continued with reference to Figures 3 , 4 , 6 , and 7 , the aforementioned base plate portion 21 defines a horizontal orientation, the cap lid portion 12 includes a base 122 extending in the aforementioned horizontal direction, which is integrally connected between the aforementioned tuning screw portion 11 and the aforementioned cap brim portion 121 . The cap portion 12 is analogous to a cap, and it is of course understandable that the cap includes a horizontally extended base 122 located at the top, which functions to connect the aforementioned tuning screw portion 11 extending in the aforementioned vertical direction and the aforementioned cap brim portion 121 extending in the aforementioned vertical direction.

[0024] Referring to Figs. Such a setup facilitates the mounting depth of the preceding adjusting screw portion 11 through the preceding through hole 20 and extending below and partially extending downward with respect to the preceding cover plate 2, such that the cap cover portion 12 is able to rely on the fit between the preceding internal threads 120 and the aforementioned external threads 220 to screw and suspend the cylinder portion 22 on the preceding cover plate 2.

[0025] Referring to Figs. When the second height H2 is 1 / 2 of the first height H1, the exposed and unexposed portions of the preceding tuning screw portion 11 with respect to the cap brim portion 121 each occupy half, i.e., the tuning screw portion 11 has half of a length for regulating it with respect to the lid The installation depth of plate 2, that is, the frequency adjustment range is relatively small; Of course, the range of the aforementioned second height H2 and the aforementioned first height H1 is not specifically limited, it is only necessary to satisfy that the aforementioned second height H2 is less than the aforementioned first height H1, so that the aforementioned tuning screw portion 11 has an exposed part relative to the aforementioned cap brim portion 121 .

[0026] Referring to Figures 4 and 7, the aforementioned adjusting screw 1 is integrally injection molded. Specifically, the adjusting screw rod portion 11 can be considered as being deposited downwards from the center of the aforementioned base 122 during the injection molding process. An annular space 10 exists between the aforementioned adjusting screw rod portion 11, the aforementioned base 122, and the aforementioned brim portion 121, with at least a portion of the aforementioned column portion 22 located within the annular space 10. The function of the annular space 10 is to accommodate a portion of the aforementioned column portion 22 during the vertical adjustment and installation of the aforementioned adjusting screw 1 relative to the aforementioned cover plate 2, providing corresponding space for movement.

[0027] Referring to Figures 3, 4, and 7, the aforementioned adjusting screw portion 11 includes an inner surface 111 and an outer surface 112 arranged in opposite directions. The bottom of the adjusting screw portion 11 away from the aforementioned base 122 is closed, while the top of the adjusting screw portion 11 near the aforementioned base 122 is open. This arrangement is intended to facilitate the integral molding of the aforementioned adjusting screw 1 and to reduce the weight of the aforementioned adjusting screw 1, thereby achieving product lightweighting.

[0028] Referring to Figures 6 and 7, the aforementioned brim portion 121 includes an inner wall surface 1211 and an outer wall surface 1212 arranged in opposite directions. It should be noted that the aforementioned inner wall surface 1211 is a circular surface, which is beneficial for etching and forming the aforementioned internal thread 120 on the aforementioned inner wall surface 1211; the aforementioned outer wall surface 1212 consists of a plurality of planes connected end to end, and the outer edge of the aforementioned base 122 is a polygon. In a specific embodiment, the outer edge of the aforementioned outer wall surface 1212 looks like the outer contour of a hexagonal nut. This arrangement facilitates adjustment by turning the aforementioned adjusting screw 1 with a tool.

[0029] Referring to Figures 6 and 7, the aforementioned cylindrical portion 22 includes an inner ring surface 2201 and an outer ring surface 2202 arranged in opposite directions. It should be noted that the outer ring surface 2202 is a circular surface, which facilitates the etching and forming of the external thread 220 on the outer ring surface 2202. It should also be specifically noted that the etching height of the internal thread 120 on the inner wall surface 1211 is the same as the etching height of the external thread 220 on the outer ring surface 2202. That is, when the highest point of the internal thread 120 is aligned with the highest point of the external thread 220, the lowest point of the internal thread 120 is also aligned with the lowest point of the external thread 220. Therefore, a fully matched meshing state between the internal thread 120 and the external thread 220 can be guaranteed.

[0030] Continuing with reference to Figure 7 , the aforementioned cap brim portion 121 also includes an inner bottom surface 1213 , and the aforementioned cap lid portion 12 also includes a cap mouth portion 123 , which is the third height H3 to the aforementioned cap mouth portion 123 . That is, the invention also reserves a distance between the bottom of the preceding external thread 220 and the upper surface of the preceding substrate portion 21 and between the cap and mouth portion 123 and the aforementioned inner bottom surface 1213 to facilitate the screwing between the preceding internal thread 120 and the preceding external thread 220 after the screwing between the said internal thread 120 and the said external thread 220 is fully fitted into place. Thus, that is, to reduce the number of helical turns of the aforementioned internal thread 120 and the aforementioned external thread 220 as much as possible, it is also possible to increase the adjustment depth of the aforementioned tuning screw 1 as much as possible.

[0031] 7 to 14. The RF regulated structure of the invention also includes a base 3 . The base 3 is located below the cover plate 2 and a cavity 30 is formed between the cover plate 2 and the base 3 . The thread of the preceding tuning screw 1 is mounted on the cover plate 2 of the preceding and extends into the cavity 30 of the preceding cavity for frequency regulation. It is specifically noted that the preceding cavity 30 includes two types: the first refers to a first cavity 301 enclosed only by an outer wall surrounding the preceding base 3 ; Therefore, the wall thickness of the first cavity 301 is different from that of the second cavity 302. It can be understood that the wall thickness of the second cavity 302 is greater than the wall thickness of the first cavity 301 , so the shielding effect is good, in terms of the efficiency of frequency regulation, more significant and more efficient. The modulator 1 of the radiofrequency modulated structure of the present invention is a plural, part of the preceding modulator 1 extends into the preceding first cavity 301 and the remaining part of the preceding modulator 1 extends into the preceding second cavity 302 . Such a setup allows for targeted modulation of the frequency by dividing the aforementioned tuning screw 1 into different types. For example: if the regulatory efficiency of the tuning screw 1 in the first cavity 301 is set to Level 1, the tuning performance of the tuning screw 1 in the second cavity 302 may be referred to as Level 2 . That is, the conditioning efficiency of the tuning screw 1 within the second cavity 302 is twice that of the tuning screw 1 in the first cavity 301 . Such frequency regulation of the radiofrequency modulation structure of the present invention is capable of separately modulating control by means of a plurality of modulation screws 1 having different regulation efficacy of primary and secondary levels.

[0032] In summary, by providing an internal thread 120 on the cap portion 12 of the aforementioned adjusting screw 1 and an external thread 220 on the cylindrical portion 22 of the aforementioned cover plate 2, when the aforementioned adjusting screw rod portion 11 passes through the through hole 20 on the cylindrical portion 22 of the aforementioned cover plate 2, the aforementioned adjusting screw 1 can adjust its installation depth relative to the aforementioned cover plate 2 to adjust the frequency by relying on the cooperation between the aforementioned internal thread 120 and the aforementioned external thread 220. At the same time, the debris generated by the helical cooperation between the internal thread 120 and the external thread 220 is blocked outside the aforementioned cover plate 2 by the cylindrical portion 22 of the aforementioned cover plate 2, preventing debris from falling into the cavity 30 below the cover plate 2 through the aforementioned through hole 20, improving intermodulation, and further optimizing the frequency modulation effect.
