Description

Technical Field

[0001] This utility model relates to the field of antennas, and more specifically, to an antenna vibrator and an antenna. Background Technology

[0002] An antenna element consists of an element box, an element tube mounted on the element box, and an element circuit board placed inside the element box. The element box is installed on the antenna main mast. The element tube is relatively long and occupies a lot of space, thus increasing the packaging volume of the antenna. Antenna manufacturers usually disassemble the element tube and package it as individual parts, but this results in the antenna requiring multiple parts to be assembled with tools, which takes a long time to install. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an antenna vibrator and an antenna including the antenna vibrator, wherein the vibrator tube does not need to be removed from the vibrator box, which is convenient to install and can save the packaging volume of the antenna.

[0004] On the one hand, the technical solution provided by this utility model is as follows:

[0005] An antenna vibrator includes a vibrator box, a vibrator tube mounted on the vibrator box, and a vibrator circuit board mounted inside the vibrator box. The vibrator tube and the vibrator circuit board are connected. The vibrator tube includes two U-shaped tubes. Bases are provided on opposite sides of the vibrator box. Rotating components are sleeved at both ends of the U-shaped tubes. The rotating components are movably mounted on the bases and can rotate on the bases.

[0006] The base and the rotating component are provided with mutually cooperating limiting structures. The limiting structures are used to restrict the rotating component to a first limiting position or a second limiting position. When the rotating component is restricted to the first limiting position, the two U-shaped tubes are in a horizontal position. When the rotating component is restricted to the second limiting position, the two U-shaped tubes are in a vertical position.

[0007] The antenna element also includes fasteners. After the rotating part is limited, the fasteners are locked to fix the base and the rotating part.

[0008] As a preferred structure of this utility model, the mutually cooperating limiting structure provided on the base and the rotating part is a groove and concave-convex structure.

[0009] As a preferred structure of this utility model, the base has a mounting hole one, and the fastener is a bolt structure. The screw of the bolt structure passes through the mounting hole two of the rotating part and enters the mounting hole one, so that the rotating part is movably mounted on the base and the rotating part can rotate on the base.

[0010] As a further improvement to the above preferred structure, a cross-shaped groove is provided on the end face of the base. The cross-shaped groove is centered on the mounting hole one of the base. The rotating part is provided with a protrusion one. The protrusion one and the groove form a slot-groove structure. When the protrusion one is engaged in the longitudinal arm of the groove, the rotating part is restricted to the first limit position. When the protrusion one is engaged in the transverse arm of the groove, the rotating part is restricted to the second limit position.

[0011] As a further improvement to the above-mentioned preferred structure, a cross-shaped groove is provided on the end face of the base, with the mounting hole one of the base as the center. The rotating part is provided with a cross-shaped protrusion two, with the mounting hole two of the rotating part as the center. The protrusion two and the groove form a slot-groove structure. The rotation of the protrusion two restricts the rotating part to the first limit position or the second limit position.

[0012] Furthermore, the rotating component is provided with a columnar protrusion three, and the mounting hole two of the rotating component passes through the protrusion three, with the protrusion two arranged along the outer periphery of the protrusion three.

[0013] Furthermore, the bolt structure is a butterfly-type manual fastening element.

[0014] Furthermore, the butterfly-type manual fastening element includes a semi-threaded screw and a wing nut. The semi-threaded screw passes through a base and two rotating parts on a U-shaped tube, with the base positioned between the two rotating parts on the U-shaped tube.

[0015] As a preferred structure of this utility model, the structure in which the oscillator tube and the oscillator circuit board are connected is specifically as follows:

[0016] The antenna vibrator also includes a metal sheet. One end of the metal sheet is clamped between the rotating part and the base. The screw that passes through the mounting hole two of the rotating part also passes through the metal sheet. The end of the U-shaped tube contacts the screw inside the rotating part. The other end of the metal sheet is connected to the vibrator box through a metal part. This metal part is also connected to the antenna vibrator interface of the vibrator circuit board. Thus, the metal sheet enables the U-shaped tube to communicate with the vibrator circuit board.

[0017] On the other hand, this utility model also provides an antenna, including an antenna main rod and the aforementioned antenna vibrator, wherein the vibrator box in the antenna vibrator is installed on the antenna main rod.

[0018] In this invention, rotating parts are installed at both ends of the U-shaped tube. The rotating parts are movably mounted on the base of the vibrator box and can rotate on the base. The U-shaped tube does not need to be removed from the vibrator box during antenna packaging. The base and rotating parts are provided with mutually cooperating limiting structures. When installing the antenna vibrator, the rotating parts are rotated to the first limiting position. At this time, the two U-shaped tubes are in a horizontal position, which is the working position of the antenna vibrator. The installation process is simple and quick. When packaging the antenna vibrator, the rotating parts are rotated to the second limiting position. At this time, the two U-shaped tubes are in a vertical position. The spatial size of the antenna vibrator is reduced, and it can also be matched with the size of other antenna structures, saving the overall packaging volume of the antenna. The U-shaped tube does not need to be removed from the vibrator box 1 during antenna packaging. After the rotating parts are limited, the fasteners are used to fix the base and rotating parts.

[0019] In this invention, the fasteners can be semi-threaded screws and wing nuts. The semi-threaded screws pass through the rotating parts installed at both ends of the U-shaped tube, and the base is installed between the rotating parts at both ends of the U-shaped tube, so that the base and the rotating parts can be manually tightened or loosened quickly.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1 to 5 An antenna vibrator includes a vibrator box 1, a vibrator tube 2 mounted on the vibrator box 1, and a vibrator circuit board 13 mounted inside the vibrator box 1. The vibrator tube 2 and the vibrator circuit board 13 are connected. The vibrator tube 2 includes two U-shaped tubes 3. The vibrator box 1 has a base 4 on each of its opposite sides. Each end of the U-shaped tube 3 is fitted with a rotating part 5. A butterfly-type manual fastening element is selected as the fastener 16 of the antenna vibrator. The butterfly-type manual fastening element includes a semi-threaded screw 6 and a butterfly nut 7. The semi-threaded screw 6 passes through the base 4 and the two rotating parts 5 on one of the U-shaped tubes 3. The base 4 is mounted between the two rotating parts 5 on one of the U-shaped tubes 3. The hexagonal head of the semi-threaded screw 6 is engaged with the screw head seat of one of the transmission parts 5. When the butterfly nut 7 is loosened, the rotating part 5 is movably mounted on the base 4 and can rotate on the base 4.

[0030] See Figure 6 and Figure 7 The through hole for the semi-threaded screw 6 to pass through the base 4 is mounting hole 1 8, and the through hole for the semi-threaded screw 6 to pass through the rotating part 5 is mounting hole 2 9.

[0031] A cross-shaped groove 10 is formed on the end face of the base 4, with the mounting hole 8 of the base 4 as the center. The rotating component 5 has a cross-shaped protrusion 11, with the mounting hole 9 of the rotating component 5 as the center. The rotating component 5 also has a columnar protrusion 12, through which the mounting hole 9 of the rotating component 5 passes. The protrusion 11 is located along the outer periphery of the protrusion 12. The protrusion 11 and the groove 10 form a slot-and-groove structure, which is a mutually cooperating limiting structure. The rotation of the protrusion 11 restricts the rotating component 5 to either the first limiting position or the second limiting position.

[0032] See Figure 1 When the rotating part 5 is restricted to the first limit position, the two U-shaped tubes 3 are in a horizontal position, which is the working position of the antenna vibrator. See [link / reference]. Figure 8 When the rotating part 5 is restricted to the second limit position, the two U-shaped tubes 3 are in a vertical position.

[0033] See Figures 2 to 5 The structure connecting the oscillator tube 2 and the oscillator circuit board 13 is specifically as follows:

[0034] The antenna vibrator also includes a metal sheet 14. One end of the metal sheet 14 is clamped between the rotating part 5 and the base 4. The semi-threaded screw 6, which passes through the mounting hole 2 9 of the rotating part 5, also passes through the metal sheet 14. The end of the U-shaped tube 3 contacts the semi-threaded screw 6 inside the rotating part 5. The other end of the metal sheet 14 is connected to the vibrator box 1 through a metal part 15. The metal part 15 is also connected to the antenna vibrator interface of the vibrator circuit board 13. Thus, the metal sheet 14 enables the U-shaped tube 3 to communicate with the vibrator circuit board 13.

[0035] In this embodiment, the metal part 15 is a bolt that mates with a nut.

[0036] In this embodiment, rotating parts 5 are installed at both ends of the U-shaped tube 3. The semi-threaded screw 6 movably mounts the two rotating parts 5 of one U-shaped tube 3 onto the base 4 of the vibrator box 1, and the rotating parts 5 can rotate on the base 4. When the antenna vibrator is installed, the rotating parts 5 are rotated to rotate the cross-shaped protrusion 11 of the rotating parts 5 to the first limit position. At this time, the two U-shaped tubes 3 are in a horizontal position. The wing nut 7 is locked, and the rotating parts 5 and the base 4 are fixed. When the antenna vibrator is packaged, the wing nut 7 is loosened, the rotating parts 5 are rotated, and the cross-shaped protrusion 11 of the rotating parts 5 is rotated to the second limit position. At this time, the two U-shaped tubes 3 are in a vertical position. The spatial size of the antenna vibrator is reduced, and it can also be matched with the size of other antenna structures, saving the packaging volume of the entire antenna. The U-shaped tube 3 does not need to be removed from the vibrator box 1 when the antenna is packaged.

[0037] The installation or packaging of the antenna vibrator can be completed by rotating the rotating part 5 and manually tightening or loosening the wing nut 7. The structure is simple, convenient and quick.

[0038] In this embodiment, the second protrusion 11 and the groove 10 can be of other shapes, as long as they can form a slotted structure. The rotation of the second protrusion 11 restricts the rotating member 5 to the first or second limiting position. Based on the cross-shaped position of the U-shaped tube 3 when it is unfolded and retracted, this embodiment uses a cross-shaped second protrusion 11 and groove 10 to ensure accurate positioning of the rotating member 5 after rotation, which facilitates manual tightening of the wing nut 7 afterwards.

[0039] The antenna vibrator and antenna provided in the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the structure of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
