Description

Technical Field

[0001] This invention relates to the field of radio frequency, and in particular to a radio frequency modulation structure. Background Technology

[0002] In current RF modulation structures, an adjusting screw engages with a threaded hole on a cover plate, and the frequency between the screw and the resonant rod is adjusted by rotation. In existing technology, the rotating adjusting screw rubs against the inner wall of the threaded hole in the cover plate, generating metal debris. This metal debris can fall into the functional cavity, easily causing short circuits between the screw and the resonant rod, or leading to poor intermodulation. Existing RF modulation structures require disassembly and cleaning, followed by readjustment, which generates metal debris again. Therefore, a certain percentage of products require secondary or even multiple disassembly and cleaning operations. Consequently, existing RF modulation structures suffer from low production yield and high maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to provide a radio frequency conditioning structure that reduces the risk of metal debris falling into the functional cavity, eliminates the need for frequent disassembly and cleaning, achieves high production yield, and reduces maintenance costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a radio frequency modulation structure, comprising:

[0005] Base;

[0006] A lower cover plate is disposed on the base, and the lower cover plate and the base form a functional cavity. The lower cover plate includes a first part that is deformable and located in the middle and a second part that is fixed and non-deformable and located around the first part. The first part has an upper surface facing away from the functional cavity and a lower surface facing the functional cavity.

[0007] A resonant rod is housed in the functional cavity, fixed to the base, and spaced below the first part;

[0008] The upper cover plate is fixed to the lower cover plate and has at least one screw hole;

[0009] At least one adjustable screw is inserted into the screw hole from top to bottom. The bottom end of the adjustable screw is located above the first part and abuts against the upper surface of the first part. When the adjustable screw is screwed downward, it can cause the first part to deform toward the resonant rod.

[0010] As a further improvement of the present invention, the second part is provided with a central opening, and the first part is installed on the second part and fills the central opening.

[0011] As a further improvement of the present invention, the first part is integrally formed with the second part by processing.

[0012] As a further improvement of the present invention, it also includes a lifting hook. The first part includes an integrally formed annular main body and a central positioning part. The annular main body surrounds the central positioning part. The lifting hook is mounted on the central positioning part and extends upward through the upper cover plate. The central positioning part is provided with a through hole that allows the lifting hook to pass through vertically.

[0013] As a further improvement of the present invention, there are multiple adjustable screws, which are respectively disposed on the annular main body. The multiple adjustable screws can press against the annular main body to deform the first part.

[0014] As a further improvement of the present invention, the adjustable screw has a hollow cavity, the adjustable screw is aligned vertically with the central positioning part, the lifting hook passes through the through hole and the hollow cavity upward through the upper cover plate and protrudes from the top of the adjustable screw, and the adjustable screw can press against the central positioning part to deform the first part.

[0015] As a further improvement of the present invention, the lifting hook includes a gripping part and a bent part located at the bottom end of the gripping part, the bent part hooks the lower part of the central positioning part, and the gripping part protrudes above the central positioning part.

[0016] As a further improved technical solution of the present invention, the upper cover plate includes an upper adjacent surface adjacent to the second part, the second part includes a lower adjacent surface adjacent to the upper cover plate, the central positioning part protrudes upward from the annular main body part and the top surface of the central positioning part is lower than the upper adjacent surface and the lower adjacent surface.

[0017] As a further improvement of the present invention, when the first part is installed at the central opening, the first part further includes an overlapping portion formed by the annular main body extending integrally and bending upward, the overlapping portion being sandwiched between the upper adjacent surface and the lower adjacent surface.

[0018] As a further improvement of the present invention, the annular main body is an annular shape with a center, and the center of the central positioning part is located at the center of the annular main body.

[0019] As a further improvement of the present invention, the upper cover plate is also provided with a central hole for the lifting hook to pass through upward.

[0020] As a further improvement of the present invention, the screw hole is only one and overlaps with the central hole to form a through hole.

[0021] Compared to existing technologies, this invention features a screw hole on the upper cover plate and a deformable first part in the middle of the lower cover plate. An adjustable screw passes through the screw hole in the upper cover plate and abuts against the first part. During downward rotation of the adjustable screw, the first part deforms towards the resonant rod, allowing the adjustable screw, the first part, and the resonant rod below it to work together to adjust the frequency. Because the adjustable screw passes through the upper cover plate but abuts against the deformable first part of the lower cover plate, it never actually passes through the lower cover plate during frequency adjustment. Metal debris generated during the rotation of the adjustable screw with the upper cover plate is trapped and collected on the lower cover plate. Therefore, this invention reduces the risk of metal debris falling into the functional cavity without requiring frequent disassembly and cleaning, resulting in high production yield and reduced maintenance costs.

If several embodiments exist, features in these embodiments may be combined with each other without conflict. When the description refers to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements.

The singular forms “a,” “the,” or “the” as used in the specification and claims of this invention are also intended to include the plural forms unless the context clearly indicates otherwise.

[0049] It should be understood that the terms "first," "second," and similar words used in the specification and claims of this invention do not indicate any order, quantity, or importance, but are merely used to distinguish features. Similarly, the terms "an" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one. Unless otherwise stated, the terms "front," "back," "left," "right," "upper," "lower," and similar words appearing in this invention are for ease of explanation only and are not limited to a specific location or spatial orientation. The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" encompasses the element following "comprising" or "including" and its equivalents, but this does not preclude the element preceding "comprising" or "including" from also including other elements. In this invention, the term "several" means two or more.

[0050] Please refer to Figures 1 to 25 As shown, the present invention relates to a radio frequency adjustment structure 100, comprising: a base 1, a lower cover plate 2, a resonant rod 3, an upper cover plate 4, and at least one adjustable screw 5. The lower cover plate 2 covers the base 1, and the lower cover plate 2 and the base 1 enclose a functional cavity 10. The lower cover plate 2 includes a deformable first portion 21 located in the middle and a fixed, non-deformable second portion 22 located around the first portion 21. The first portion 21 has an upper surface facing away from the functional cavity 10 and a lower surface facing the functional cavity 10. The resonant rod 3 is fixed inside the base 1 and spaced below the first portion 21. The upper cover plate 4 is fixed on the lower cover plate 2 and has at least one screw hole 40. Both the lower cover plate 2 and the upper cover plate 4 are made of metal plates. Therefore, when at least one of the adjustable screws 5 is inserted into the screw hole 40 from top to bottom and the adjustable screw 5 is screwed, metal shavings will be generated between the adjustable screw 5 and the inner wall surface of the screw hole 40 of the upper cover plate 4. Because the bottom end of the adjustable screw 5 is located above the first part 21 and abuts against the upper surface of the first part 21, the first part 21 can deform towards the resonant rod 3 during the downward screwing process. In other words, throughout the frequency adjustment process, the adjustable screw 5 never passes through the lower cover plate 2, and the metal debris generated during the screwing process with the upper cover plate 4 is blocked and collected on the lower cover plate 2. Therefore, the RF adjustment structure 100 of this invention reduces the risk of metal debris generated during frequency modulation falling into the functional cavity 10, eliminates the need for frequent disassembly and cleaning, achieves high production yield, and reduces maintenance costs.

[0051] As described above, the lower cover plate 2, like the upper cover plate 4 which has the screw holes 40, is typically made of metal. Please refer to... Figures 1 to 10The first and second embodiments of the radio frequency modulation structure 100 of the present invention are shown. In each embodiment, the second part 22 of the radio frequency modulation structure 100 has a central opening 20. The first part 21 is mounted on the second part 22 and fills the central opening 20. This separate design of the first part 21 and the second part 22 facilitates the independent molding and replacement of the first part 21. Please refer to... Figures 11 to 15 In the third embodiment of the radio frequency modulation structure 100 of the present invention shown, the first part 21 is integrally formed with the second part 22 by processing a metal plate. Specifically, the processing method can be a stretching method for the metal plate. Stretching is performed on the middle of the originally rigid metal plate, making the middle of the metal plate thinner and softer, thus giving it a certain degree of elasticity, meaning it can be deformed by pressure. By using this stretching processing method, the first part 21 and the second part 22 are integrated, avoiding the need for opening holes in the lower cover plate 2 made of metal plate material, making full use of the entire metal plate, and saving a subsequent installation step. For a clearer illustration,

[0052] Figure 20 The first part 21 and the second part 22 are shown to be separate units;

[0053] Figure 21 The diagram shows that the first part 21 and the second part 22 are integrated into one unit. In other words, the lower cover plate 2 of the radio frequency modulation structure 100 of the present invention has two configuration methods as described above.

[0054] Please refer to Figures 1 to 25 And focus on referring to Figures 22 to 24 As shown, the radio frequency adjustment structure 100 of the present invention also includes a lifting hook 6. The first part 21 includes an integrally formed annular main body 211 and a central positioning part 212, wherein the annular main body 211 surrounds the central positioning part 212. The lifting hook 6 is mounted on the central positioning part 212 and extends upward through the upper cover plate 4. Please refer to... Figure 20 and Figure 21As shown, the central positioning part 212 is provided with a through hole 2120 through which the lifting hook 6 passes vertically. Because the bottom end of the adjustable screw 5 is located above the first part 21 and abuts against the upper surface of the first part 21, the first part 21 can deform towards the resonant rod 3 when the adjustable screw 5 is screwed downward. Normally, the first part 21 relies on its own elasticity to rebound, that is, the first part 21 will naturally rebound when the adjustable screw 5 is screwed upward in the opposite direction. The purpose of setting the lifting hook 6 is to not only rely on the natural rebound of the first part 21, but also rely on human assistance to help the first part 21 rebound upward, that is, to lift and rebound. This setting avoids elastic fatigue of the first part 21 after being pressed repeatedly, making it easier for the first part 21 to return to its original position.

[0055] Please refer to Figures 1 to 5 and Figure 22 In the illustrated embodiment, there are two adjustable screws 5. The two adjustable screws 5 are symmetrically arranged on opposite sides of the central positioning part 212. Each of the two adjustable screws 5 can press against the annular main body 211, causing the first part 21 to deform. When the two adjustable screws 5 are turned simultaneously, each adjustable screw 5 applies force to one side of the central positioning part 212, ensuring that the external force applied to the first part 21 is distributed on both sides. This avoids the force being concentrated in one place, which could cause significant deformation of a certain part of the first part 21, potentially damaging the resonant rod 3 below. It is easy to imagine that the case of two adjustable screws 5 in Embodiment 1 can be extended to multiple adjustable screws 5. Multiple adjustable screws 5 are respectively disposed on the annular main body 211. Multiple adjustable screws 5 can press against the annular main body 211 to deform the first part 21. This can also avoid the damage caused by a large deformation of a certain part of the first part 21 due to the force being concentrated in one place.

[0056] Please refer to Figures 6 to 10 , Figure 23 The second embodiment shown, and Figures 11 to 15 , Figure 24In the illustrated embodiment three, the adjustable screw 5 has a hollow cavity 50. The adjustable screw 5 is vertically aligned with the central positioning part 212. The lifting hook 6 extends upward from the through hole 2120 and the hollow cavity 50 through the upper cover plate 4 and protrudes from the top of the adjustable screw 5. The adjustable screw 5 can press against the central positioning part 212, causing the first part 21 to deform. By configuring the adjustable screw 5 with a hollow cavity 50 in this way, the adjustable screw 5 and the lifting hook 6 can be integrated into one place, saving product space and making the product structure more compact.

[0057] Therefore, the arrangement state, i.e., the relative positional relationship, between the adjustable screw 5 and the lifting hook 6 can be one of two types: a state in which the adjustable screw 5 and the lifting hook 6 are separated (referred to as the separated state) and a state in which the adjustable screw 5 and the lifting hook 6 are integrated together (referred to as the integrated state). These two arrangement states between the adjustable screw 5 and the lifting hook 6, along with the two arrangement methods between the first part 21 and the second part 22 of the lower cover plate 2, can be combined to form various embodiments. This invention only details embodiments one, two, and three as shown above. In embodiment one, the adjustable screw 5 and the lifting hook 6 are separate, and the first part 21 and the second part 22 are separately configured. In embodiment two, the adjustable screw 5 and the lifting hook 6 are integrated, while the first part 21 and the second part 22 are separately configured. In embodiment three, the adjustable screw 5 and the lifting hook 6 are integrated, while the first part 21 and the second part 22 are integrally configured. In fact, there can be a fourth combination: please refer to [reference needed]. Figure 25 The fourth embodiment shown is a combination in which the adjustable screw 5 and the lifting hook 6 are separated, and the first part 21 and the second part 22 are integrally formed.

[0058] Please refer to Figures 22 to 25As shown in the specific embodiment, the lifting hook 6 is made of wound metal wire, including a gripping part 61 and two bent parts 62 located at opposite ends of the gripping part 61. In other embodiments, the lifting hook 6 may also include a gripping part 61 and at least one bent part 62 located at the bottom end of the gripping part 61. Furthermore, the lifting hook 6 may not be made of wound metal wire but by other processes, as long as it ensures that there is a gripping part 61 at the top and a bent part 62 at the bottom. For example, the bottom end of the gripping part 61 may be provided with a bent part 62 in an L-shape. The bent part 62 hooks onto the lower part of the central positioning part 212, while the gripping part 61 protrudes above the central positioning part 212. This simple winding method facilitates the forming of the lifting hook 6 and its positioning and installation on the lower cover plate 2, and also helps control costs.

[0059] Please continue to refer to Figures 22 to 25 As shown, the upper cover plate 4 includes an upper adjacent surface 422 adjacent to the second part 22, and the second part 22 includes a lower adjacent surface 224 adjacent to the upper cover plate 4. The central positioning part 212 protrudes upward from the annular main body part 211, and the top surface of the central positioning part 212 is lower than the upper adjacent surface 422 and the lower adjacent surface 224. In fact, the central positioning part 212 does not necessarily have to protrude upward from the annular main body part 211. The central positioning part 212 and the annular main body part 211 can also perform the positioning function for the lifting member 6 when they are on the same plane. In a specific embodiment, the central positioning part 212 is set to protrude upward from the surface of the annular main body part 211, and the lower part of the central positioning part 212 is recessed to form the receiving cavity of the bent part 62. This arrangement is more conducive to the positioning of the lifting member 6 and the positioning effect is better.

[0060] Please refer to Figure 2 , Figure 4 , Figure 7 , Figure 9 as well as Figure 22 , 23 As shown, when the first part 21 is installed at the central opening 20, the first part 21 also includes an overlapping portion 213 formed by integrally extending and bending the annular main body 211 upwards. The overlapping portion 213 is sandwiched between the upper adjacent surface 422 and the lower adjacent surface 224. The purpose of providing the overlapping portion 213 is to facilitate the installation of the first part 21 on the second part 22. The overlapping portion 213 is provided with several holes to facilitate the passage of the second fastener 72 described below, allowing the first part 21 to be installed on the second part 22. This arrangement also provides stability and ease of disassembly for the installation of the first part 21 on the second part 22.

[0061] Please refer to Figure 2 , Figure 7 and Figure 12 As shown, the annular main body 211 is a ring with a center, and the center of the central positioning part 212 is located at the center of the annular main body 211. This facilitates a symmetrical arrangement of the structure of the radio frequency modulation structure 100 of the present invention.

[0062] Undoubtedly, the upper cover plate 4 also has a central hole 41 for the lifting hook 6 to pass upwards. When the adjustable screw 5 and the screw hole 40 are only two symmetrically arranged, please refer to... Figure 2 As shown, the two screw holes 40 are symmetrically distributed on opposite sides of the central hole 41; and in conjunction with reference to... Figure 7 and Figure 12 As shown, when there is only one adjustable screw 5 and one screw hole 40, the screw hole 40 overlaps with the center hole 41 to form... Figure 7 and Figure 12 The through hole 401 allows the adjustable screw 5 to pass through while also causing the lifting hook 6 to protrude upward from the upper cover plate 4.

[0063] Please refer to Figures 1 to 25 As shown, the radio frequency conditioning structure 100 also includes a plurality of fasteners 7.

[0064] First, please refer to Figures 1 to 15 as well as Figure 16 and Figure 17 As shown, the fastener 7 includes a plurality of first fasteners 71. Please refer to... Figure 16 and Figure 17 As shown, since the three components to be positioned by the first fastener 71 are, in order, the upper cover plate 4 at the top, the lower cover plate 2 where the second part 22 is located, and the base 1 at the bottom, the first fastener 71 uses a long bolt of a certain length for fixing the upper cover plate 4 to the second part 22 and the base 1. The upper cover plate 4 is provided with several first holes 4001 through which the long bolt passes, and the second part 22 is provided with several second holes 2201 through which the long bolt passes. Of course, the base 1 is also provided with holes for easy locking.

[0065] Secondly, please refer to Figures 1 to 15 as well as Figure 18 and Figure 19As shown, the fastener 7 also includes several second fasteners 72. Because the first fastener 71 is used for fixing the first part 21 and the second part 22, and the positioning is for the upper and lower components, the second fasteners 72 are ordinary bolts. The first part 21 is provided with several third holes 2102 for the ordinary bolts to pass through, and the second part 22 is provided with several fourth holes 2202 for locking the ordinary bolts in place.

[0066] Please refer to Figure 2 , Figure 7 and Figure 20 As shown, the upper cover plate 4 is also provided with a plurality of fifth holes 4002 for receiving and exposing the second fastener 72. This arrangement facilitates the operation of the second fastener 72 by personnel. A plurality of first fasteners 71 and a plurality of second fasteners 72 are each arranged in a ring at intervals, with the first fasteners 71 located on the outer ring and the second fasteners 72 located on the inner ring. A plurality of second holes 2201 and a plurality of fourth holes 2202 on the second portion 22 are also arranged in corresponding inner and outer rings, with the plurality of second holes 2201 surrounding the plurality of fourth holes 2202. Similarly, a plurality of first holes 4001 and a plurality of fifth holes 4002 on the upper cover plate 4 are also arranged in corresponding inner and outer rings, with the plurality of first holes 4001 surrounding the plurality of fifth holes 4002.

[0067] Please refer to Figure 2 , Figure 5 , Figure 7 , Figure 10 , Figure 2 and Figure 15 As shown, the fastener 7 also includes a third fastener 73 for fixing the resonant rod 3 to the base 1. The base 1 has a protrusion 11, and the third fastener 73 positions the resonant rod 3 on the protrusion 11. The third fastener 73 can be a long bolt like the first fastener 71, or a regular bolt like the second fastener 72. The customer can choose freely according to the height of the protrusion 11.

[0068] In summary, since the adjustable screw 5 never passes through the lower cover plate 2 during the entire frequency adjustment process, the metal debris generated by the adjustable screw 5 during the screwing process with the upper cover plate 4 is blocked and collected on the lower cover plate 2. Therefore, the RF adjustment structure 100 of the present invention reduces the risk of metal debris generated during the frequency adjustment process falling into the functional cavity 10, eliminates the need for frequent disassembly and cleaning, achieves high production yield, and reduces maintenance costs.

[0069] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on those skilled in the art. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention.
