Technical Field

[0001] This application relates to the technical field of suction cup antennas, and in particular to a fixing device for a suction cup antenna. Background Technology

[0002] An antenna is a device used to radiate and receive electromagnetic waves. It is a core component of wireless communication, radar, broadcasting, remote sensing and other systems. Its essence is a "transducer" that converts electrical signals into electromagnetic waves. Through specific structural design, it realizes the directional transmission or reception of signals, thereby realizing the transmission and detection of wireless information.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, traditional suction cup antenna fixing devices mainly rely on a single suction cup structure for fixation. In actual use, especially in scenarios such as vehicle movement or equipment vibration, this single fixing method is not stable enough and is prone to loosening. This not only affects the antenna's signal reception effect but may also cause the antenna to fall off. Utility Model Content

[0019] Please see Figure 4 As shown, a sliding groove 3 is provided on the left side of the connecting cylinder 12, and a pressing block 31 is slidably connected to the inner wall of the sliding groove 3.

[0020] Please see Figure 2 As shown, a rotating block 211 is fixedly connected to the top of the threaded rod 21. The outer wall of the rotating block 211 is provided with an anti-slip groove to prevent the user from slipping when turning it. The bottom of the threaded rod 21 is rotatably connected to the top of the annular connecting plate 22 through a rotating shaft 212. A movable column 23 is fixedly connected to the top of the push plate 231.

[0021] Please see Figure 4As shown, a spring telescopic column 311 is fixedly connected to the left side of the pressing block 31. The setting of the spring telescopic column 311 can enable the pressing block 31 to reset after being pressed. There are two pressing blocks 31, and the right side of the pressing block 31 on the left side is fixedly connected to the left side of the spring telescopic column 311.

[0022] Please see Figure 2 As shown, the bottom of the annular connecting plate 22 is fixedly connected to the top of the movable column 23. The top of the annular protective shell 2 has a movable hole, and a limiting column 25 is slidably connected to the inner wall of the movable hole. The bottom of the limiting column 25 is fixedly connected to the top of the annular connecting plate 22. The bottom of the air cylinder 24 is fixedly connected to the top of the suction cup 26. The combination of several suction cups 26 and magnets 11 can make the overall device more stable.

[0024] Please see Figure 2 , Figure 3 As shown, there are several suction cups 26 arranged in a circular array, and several air cylinders 24 arranged in a circular array. The top of the air cylinder 24 is provided with a moving groove, and the inner wall of the moving groove is in contact with the outer wall of the moving column 23.

[0025] The implementation principle of the fixing device for a suction cup antenna in this embodiment is as follows: First, the device is placed on the metal surface to be installed. The magnet 11 at the bottom of the base 1 will immediately attract the metal surface, completing the initial fixing. Then, the rotating block 211 at the top of the threaded rod 21 is rotated. The rotating block 211 drives the threaded rod 21 to rotate in the threaded groove at the top of the annular protective shell 2. Since the bottom of the threaded rod 21 is rotatably connected to the annular connecting plate 22 through the rotating shaft 212, the rotation of the threaded rod 21 will drive the annular connecting plate 22 to move up and down. When the annular connecting plate 22 moves upward, it will push the moving column 23 and the pushing plate 231 to slide upward in the air cylinder 24. At this time, the suction cup 26 will form a negative pressure with the metal surface under the action of the pushing plate 231, so that the suction cup 26 is tightly attracted to the mounting surface, while the limiting column is also fixed. 25 slides within the moving hole, guiding and limiting the movement of the annular connecting plate 22 to ensure smooth movement. Finally, place the antenna 121 on top of the connecting cylinder 12, press the two pressing blocks 31 to compress the spring telescopic column 311, insert the limiting ring at this time, and the two hooks 32 will contact and hook with the limiting ring 33 at the bottom of the antenna 121, completing the fixation of the antenna. Press the two pressing blocks 31 to compress the spring telescopic column 311, and the hooks 32 will separate from the limiting ring 33, so that the antenna 121 can be removed from the connecting cylinder 12. Rotate the rotating block 211 in the opposite direction to drive the threaded rod 21 to move downward, and the annular connecting plate 22 will move downward accordingly, pushing the plate 231 to slide downward in the air cylinder 24. The gas in the air cylinder 24 will be ejected downward, the negative pressure in the suction cup 26 will disappear, and it will separate from the mounting surface.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
