Description

Technical Field

[0001] This utility model relates to walkie-talkie technology, and more particularly to a walkie-talkie with a detachable antenna. Background Technology

[0002] A walkie-talkie is a portable device based on radio technology that supports two-way real-time voice communication. It is mainly used for several individuals to make instant group calls over short distances (hundreds of meters to tens of kilometers). Due to its instant communication, lack of network support, and flexible networking capabilities, walkie-talkies are widely used in scenarios such as firefighting, rescue, medical emergency, construction sites, logistics, and warehousing.

[0003] Depending on the specific needs and scenarios, different frequency bands may require different antennas. For example, rescue operations in forests require low-frequency bands with strong penetration, while high-frequency bands with strong anti-interference capabilities are needed in urban areas. However, due to factors such as manufacturing processes, reliability, and waterproofing requirements, the antennas of walkie-talkies on the market are usually non-removable. Users have to purchase multiple walkie-talkies to meet different needs, resulting in a high cost and inconvenience for carrying them during operations.

[0004] To address these issues, some walkie-talkies with detachable and replaceable antennas have emerged in the market. To increase antenna reliability, a connecting female connector consisting of a nylon sleeve, base, and other components needs to be installed inside the casing. This not only increases manufacturing costs but also imposes high assembly requirements during production, resulting in long production cycles, low production efficiency, and reduced market competitiveness for enterprises. Summary of the Invention

[0005] Purpose of the utility model: The purpose of this utility model is to provide a walkie-talkie with a simple structure and a detachable and replaceable antenna.

[0006] Technical solution: The present invention relates to a walkie-talkie with a detachable antenna, comprising an antenna, an insert at the bottom of the antenna, and a hollow housing. A circuit board is disposed within the cavity of the housing, and a through hole for antenna insertion is provided at the top of the housing. A receiving component for detachable connection with the insert is provided at the top of the circuit board, and the position of the receiving component corresponds to the position of the through hole.

[0007] Furthermore, the insert is cylindrical, and the outer wall of the insert is provided with insertion threads.

[0008] Furthermore, the receiving element is a metal ring made of metal, and the inner wall of the receiving element is provided with receiving threads, which are used to match the insertion threads.

[0009] Furthermore, the receiving component is soldered onto the top of the circuit board.

[0010] Furthermore, a seal is provided between the antenna and the receiving component. The seal may be an O-ring.

[0011] Furthermore, the housing includes a front shell and a rear shell, which together form a cavity within the housing.

[0012] Furthermore, the front shell and the rear shell are detachably connected by screws.

[0013] Furthermore, the circuit board is provided with a number of positioning slots, and the rear shell is provided with a number of positioning posts for matching the positioning slots.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages: The present invention is equipped with a metal receiving component, one side of which is detachably connected to the antenna and the other side of which is connected to the circuit board. It uses fewer parts, so it is easier to assemble and the manufacturing cost is lower. The sealing component between the antenna and the receiving component also plays a waterproof role.
