Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to an anti-interference walkie-talkie antenna. Background Art

[0002] Walkie-talkies can be used for calls without any network support and without incurring any phone charges. They are suitable for relatively fixed and frequent call situations. They are composed of a casing, a host, a battery, a belt clip, a charger, and an antenna. There are three types of walkie-talkies: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies.

[0003] An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. It is a component used in radio equipment to transmit or receive electromagnetic waves.

[0004] The prior art patent document CN 204857921 U provides a vehicle-mounted walkie-talkie suction cup antenna, including: a suction cup, an antenna body, a first signal reinforcement component, a second signal reinforcement component, a connecting wire and a connecting wire storage box. The antenna body is provided on the suction cup, and the upper and lower parts of the antenna body are respectively provided with the first signal reinforcement component and the second signal reinforcement component. The connecting wire is provided on the suction cup, and the bottom of the suction cup is provided with the connecting wire storage box. Through the above method, the anti-interference performance is good, the signal strength is high, and the receiving sensitivity is high.

[0005] The above technology improves anti-interference performance by setting two signal reinforcement components, but the antenna only uses one communication frequency band. In some different terrains, the interference of this frequency band is strong, which will affect the normal operation of the above antenna. Therefore, we need an anti-interference walkie-talkie antenna. Utility Model Content

[0006] The purpose of the present invention is to provide an anti-interference walkie-talkie antenna to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an anti-interference walkie-talkie antenna, comprising a first fixing base, a connecting post fixedly connected to the top of the first fixing base, and a coil assembly provided on the outside of the connecting post, a second fixing base fixedly connected to the top of the connecting post, and a telescopic assembly provided on the top of the second fixing base;

[0008] The coil assembly includes a fixed block, and a connecting wire is fixedly connected to the interior of the fixed block, one end of the connecting wire is provided with a capacitor, and the other end of the connecting wire is fixedly connected to the coil;

[0009] The telescopic assembly includes a telescopic column, and a first limiting block is fixedly connected to the upper end inside the telescopic column, and a second limiting block is arranged at the lower end outside the telescopic column.

[0010] Preferably, a protective cap is arranged above the telescopic column, and the material of the protective cap is rubber.

[0011] Preferably, a protective shell is arranged below the protective cap, and a housing is fixedly connected to the lower part of the protective shell.

[0012] Preferably, an anti-slip sleeve is sleeved on the outside of the housing.

[0013] Preferably, a pin is fixedly connected to the lower part of the first fixing seat, and an interface is arranged below the first fixing seat.

[0014] Preferably, an external thread is provided on the outside of the interface, and it is matched with the internal thread at the socket of the walkie-talkie.

[0015] Preferably, five telescopic columns are provided, and the five telescopic columns are sleeved.

[0016] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0017] First, the present utility model is provided with a fixing seat, a connecting wire, a capacitor, and a coil. By adding a coil signal receiving device, the signal receiving frequency band is increased, so as to achieve the purpose of receiving signals in dual frequency bands. Thus, it is ensured that signals can be effectively received without replacing the receiving antenna of the walkie-talkie in different places, the transmission distance of the signal is ensured to be relatively far, the applicability of the walkie-talkie antenna is improved, and the anti-interference ability is thus improved.

[0018] Second, the present utility model is provided with a telescopic column, a first limiting block, and a second limiting block. Pull the protective cap upward to drive the telescopic column to extend. The telescopic column drives the second limiting block to move upward, and the second limiting block abuts against the first limiting block, so as to ensure that the antenna remains in an extended state. By lengthening the length of the antenna, the return loss can be reduced, and thus the technical effect of reducing the noise emitted by the walkie-talkie is achieved, enabling the user to clearly hear the information to be transmitted in the voice and improving the user experience.
