Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a foldable dipole broadcasting and television transmitting antenna. Background Art

[0002] A transmitting antenna is an electronic device that converts electrical signals into electromagnetic waves for transmission to a designated receiver, such as a broadcast station, satellite, wireless communication network, or radar system. It consists of a variety of components, and common designs include linear antennas, dipoles, directional antennas, parabolic antennas, array antennas, etc. After the antenna receives electrical signals from the feed source, it converts these electrical signals into electromagnetic waves through the transmitting oscillator. The rotating transmitting oscillator can change the direction of the transmitted signal or optimize the propagation of the signal by adjusting the polarization.

[0003] The current dipole transmitting antenna is mainly composed of a transmitting oscillator, a transmission line and a transmitting surface welded together. Although the structure is relatively stable, the transmitting oscillator, the transmission line and the transmitting surface are assembled into a whole before installation, which occupies a large space in both the horizontal and vertical directions. Therefore, when transferring and storing, the transmitting antenna as a whole will occupy a large space, which brings inconvenience to transfer, storage and installation.

[0004] In summary, there is a need for a dipole transmitting antenna that is easy to transfer and store. Utility Model Content

[0034] Embodiment 2

[0035] like Figure 2-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0036] The locking component 536 includes a first push plate 5361, a sliding rod 5362, an insert block 5363 and a spring 5364. Two sliding rods 5362 are fixed to the side wall of the first push plate 5361. The sliding rod 5362 is connected to the interior of the positioning plate 535. An insert block 5363 is fixed to the end of the sliding rod 5362 away from the first push plate 5361. The top surface of the insert block 5363 is an inclined structure. A spring 5364 is sleeved on the outer wall of the sliding rod 5362. The spring 5364 is arranged between the positioning plate 535 and the insert block 5363. The insert block 5363 is inserted into the interior of the blocking component 537.

[0037] In this embodiment, the plug-in component 537 includes a second push plate 5371, a plug-in plate 5372 and a stopper 5373. The plug-in plate 5372 is fixed to the bottom surface of the second push plate 5371. The plug-in plate 5372 is an inverted U-shaped structure. The plug-in plate 5372 is plugged into the first mounting frame 531. The stopper 5373 is fixed to the side wall of the plug-in plate 5372. The bottom surface of the plug-in plate 5372 passes through the bottom surface of the first mounting frame 531. The plug-in block 5363 is plugged into the plug-in plate 5372. The bottom surface of the plug-in plate 5372 is an inclined structure.

[0038] By inserting the insert plate 5372 into the first mounting frame 531, when the transmitting vibrator 52 is unfolded, the stop block 5373 can be used to stop and position the first flap 533, thereby ensuring the unfolded positioning of the transmitting vibrator 52. Then, when the transmitting vibrator 52 is folded, the first flap 533 is inserted into the U-shaped groove of the insert plate 5372 to achieve the positioning of the first flap 533, thereby ensuring the positioning effect of the transmitting vibrator 52 when unfolded and folded.

[0039] In this embodiment, the flip support assembly 6 includes a second mounting frame 61, a second rotating shaft 62, a second flap 63, a third rotating shaft 64, a torsion spring 65 and a third mounting frame 66. The second rotating shaft 62 is fixed to the top surface of the second flap 63, and the third rotating shaft 64 is fixed to the bottom surface. The second mounting frame 61 is fixed to the bottom surface of the transmission line 51, and the third mounting frame 66 is fixed to the side wall of the first fixing frame 3. The second rotating shaft 62 is rotatably connected to the inside of the second mounting frame 61, and the third rotating shaft 64 is rotatably connected to the inside of the third mounting frame 66. The outer wall of the third rotating shaft 64 is sleeved with a torsion spring 65, and one end of the torsion spring 65 is connected to the inner wall of the third mounting frame 66.

[0040] During the flipping process of the support frame 54, the second flap 63 is used for flipping support to ensure the stability of the entire launching mechanism 5 when flipping, folding or unfolding. When the second folding component 55 is unlocked during unfolding, the torsion spring 65 is used to flip and reset the second flap 63 to promote the flipping and unfolding of the launching mechanism 5, thereby improving the convenience of installing the transmitting antenna.

[0041] In this embodiment, a docking block 521 is fixed to one end face of the transmitting vibrator 52, and a plurality of docking ports 511 are provided on the side wall of the transmission line 51. The docking block 521 is inserted into the docking port 511 by flipping the transmitting vibrator 52.

[0042] By arranging the docking block 521 on the transmitting oscillator 52 , when the transmitting oscillator 52 is unfolded, the docking block 521 can be inserted into the docking port 511 for positioning, thereby ensuring the stability of the docking between the transmitting oscillator 52 and the transmission line 51 .

[0043] The working principle and use process of this utility model:

[0044] Press first Figure 1-Figure 5 When installing the transmitting antenna, the first folding assembly 53 and the second folding assembly 55 are unlocked first. The first folding assembly 53 and the second folding assembly 55 are unlocked in the same way. The first push plate 5361 is pulled to pull the plug block 5363 out of the plug plate 5372, and then the second push plate 5371 is pulled to pull the plug plate 5372 out of the first mounting frame 531, thereby unlocking the first flap 533.

[0045] Then, the second flap 63 is flipped under the torsion force of the torsion spring 65, so that the support frame 54 is flipped upward, the support frame 54 is unfolded, and then the second folding component 55 is locked and positioned, and then the transmitting vibrator 52 is unfolded, so that the docking block 521 is inserted into the docking port 511, so that the transmitting vibrator 52 and the transmission line 51 are unfolded and docked;

[0046] Then, each plug plate 5372 is inserted back into the first mounting frame 531. During the insertion process, the plug plate 5372 first uses the inclined surface at the bottom to push the plug block 5363 obliquely, causing the spring 5364 to contract until the plug plate 5372 is completely clamped and positioned to position the first flap 533. The spring 5364 pushes the plug block 5363 into the plug plate 5372 to lock the position of the plug plate 5372, thereby allowing the transmitting antenna to be stably deployed and installed as a whole.
