Description

Technical Field

[0001] This utility model relates to the field of electromagnetic environment testing and analysis technology, specifically a handheld antenna fast switching device. Background Technology

[0002] When conducting radio interference analysis and electromagnetic environment testing, multi-band test receiving antennas are generally used, covering frequency bands including high-frequency antennas from 200MHz to 500MHz and very high-frequency antennas from 500MHz to 7.5GHz and above.

[0003] Existing test antennas are all individually designed, and handheld antennas are mostly separate antenna and handle designs. When using relevant frequencies, the corresponding frequency band antenna needs to be installed on the handle. Once cross-frequency band testing is required, it is necessary to manually switch between different frequency band antennas multiple times, causing interruptions in testing or interference analysis, and is also detrimental to the protection of the receiving equipment's RF port, potentially causing damage to the device port.

[0006] Preferably, both the VHF antenna and the HF antenna have a connection structure at their input ends. The connection structure includes a signal input post, one end of which is rotatably connected to a ball bearing. The end of the signal input post away from the ball bearing is provided with an input line housing. A spring is sleeved on the input line housing. One end of the spring is fixedly connected to the inner wall of the converter head, and the other end is fixedly connected to the input line housing.

[0007] Preferably, the fixed cylinder has a signal input socket and a circular groove at the end facing the converter head. The groove depth of the circular groove gradually decreases in a clockwise direction, and the signal input socket is located at the lowest point of the circular groove depth.

[0008] Preferably, the handle post is equipped with a control switch, and the handle post is equipped with a battery and an RF cable output port.

[0009] Preferably, the fixed cylinder is equipped with an RF switch, and the signal input post is plugged into the RF switch.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by using the converter head and the connection structure, the VHF antenna and the HF antenna can be rotated and connected, thereby enabling fast and efficient antenna switching, avoiding manual switching of different frequency band antennas and causing interruption of testing or interference analysis.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please refer to 1-4. One embodiment of this utility model is provided: a handheld antenna quick switching device, including a handle column 1, a fixed cylinder 2 fixedly connected to the top of the handle column 1, a fixed ring 3 fixedly connected to one end of the fixed cylinder 2, a connecting rod 5 fixedly connected to the side of the fixed ring 3, and an interference fit connecting the end of the connecting rod 5 away from the fixed ring 3 to a converter head 4. The converter head 4 is provided with a sliding groove 6, and the connecting rod 5 is slidably connected to the sliding groove 6. One end of the converter head 4 is provided with a VHF antenna 7 and a HF antenna 8. By rotating the converter head 4, the VHF antenna 7 and the HF antenna 8 are brought into contact with the internal radio frequency switcher, thereby realizing quick switching of antennas of different frequencies.

[0018] Both the VHF antenna 7 and the HF antenna 8 have a connection structure 9 at their input ends. The connection structure 9 includes a signal input post 91. One end of the signal input post 91 is rotatably connected to a ball bearing 92. The end of the signal input post 91 away from the ball bearing 92 is provided with an input line housing 93. A spring 94 is sleeved on the input line housing 93. One end of the spring 94 is fixedly connected to the inner wall of the converter head 4, and the other end is fixedly connected to the input line housing 93. During rotation, the ball bearing 92 rotates, facilitating the rotation of the converter head 4. When the RF switcher is inserted, the signal input post 91 transmits information, and the spring 94 acts as a buffer. During rotation, the spring 94 is compressed, keeping the ball bearing 92 in contact with the circular groove 22 and rolling within the circular groove 22. When the RF switcher needs to be replaced, the spring 94 is compressed during rotation, causing the signal input post 91 to retract.

[0019] The fixed cylinder 2 is provided with a signal input socket 21 and a circular groove 22 at the end facing the converter head 4. The groove depth of the circular groove 22 gradually decreases in the clockwise direction. The position of the signal input socket 21 is the lowest point of the groove depth of the circular groove 22, which ensures that the signal input post 91 can be disengaged from the signal input socket 21 during the clockwise rotation of the converter head 4.

[0020] The handle column 1 is equipped with a control switch, and the handle column 1 has a battery and RF cable output port for easy manual control; the fixed cylinder 2 has an RF switch inside, and the signal input column 91 is plugged into the RF switch for easy signal switching.
