Description

Technical Field

[0001] The utility model relates to the field of radio frequency antennas, and particularly to a radio frequency antenna with a novel anti-interference structure. Background Technique

[0002] An antenna is a transducer that converts the guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or performs the reverse conversion. It is a component used to transmit or receive electromagnetic waves in radio equipment. The radio frequency antenna also belongs to a type of antenna. However, the existing radio frequency antennas are usually fixed with screws during installation, resulting in inconvenient quick installation and disassembly of the radio frequency antennas. Moreover, the anti-interference structure on the surface of the radio frequency antenna is not easy to quickly disassemble, leading to inconvenient quick maintenance of the radio frequency antenna.

[0003] To solve the above problems, a radio frequency antenna with a novel anti-interference structure is thus proposed here. Content of the Utility Model

Connecting blocks are snap-fitted inside several of the connecting card slots, and several of the connecting blocks are fixedly connected to several of the anti-interference protective covers respectively.

By pulling the auxiliary handle, the two pull ropes are driven to contract, thereby driving the two limiting blocks to contract into the two placement grooves and no longer limiting the two guiding blocks, thus facilitating the rapid disassembly and maintenance of the radio frequency antenna body.

[0011] Preferably, two fixing members are fixedly arranged on both sides of the substrate, and fixing holes are opened at the tops of the four fixing members. The fixed installation of the overall structure is facilitated by the arrangement of the four fixing members and the four fixing holes.

[0012] Preferably, an anti-interference layer is fixedly arranged inside the anti-interference protective cover. The anti-interference performance of the radio frequency antenna body can be improved by the combined setting of the anti-interference protective cover and the anti-interference layer.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

By pulling the auxiliary handle 24, the two pull ropes 17 are driven to contract, so as to drive the two limiting blocks 11 to contract into the two placement grooves 9, and no longer limit the two guide blocks 8, thus facilitating the quick disassembly and maintenance of the radio frequency antenna main body 5.

[0024] Two connection card slots 19 are opened at the connection parts of each of the plurality of radio frequency antenna main bodies 5 and each of the plurality of anti-interference protective covers 6.

At the same time, through the two limiting blocks 11 respectively engaging with the two limiting grooves 13 under the action of the two telescopic springs 10, the two guiding blocks 8 are limited, so as to realize the rapid installation of the RF antenna main body 5. When the RF antenna main body 5 needs to be disassembled and replaced, by pulling the auxiliary handle 24, the two pull ropes 17 are driven to contract, thereby driving the two limiting blocks 11 to contract into the two placement grooves 9, and no longer limiting the two guiding blocks 8, so as to facilitate the rapid disassembly and maintenance of the RF antenna main body 5.
