Technical Field

[0001] The utility model is applicable to the field of radio antennas and provides a radio antenna feeder connection structure. Background Technique

[0002] A radio antenna feeder is a cable connecting a radio antenna and a receiving circuit. Its main function is to transmit the electromagnetic signals received by the antenna to the interior of the radio for signal processing and enhancement. The quality and design of the feeder directly affect the intensity and clarity of the received signals, and thus affect the overall performance and reception effect of the radio.

[0003] A radio antenna feeder connection structure usually includes a fixed end and an adjustable end, allowing the length and position of the feeder to be adjusted during use. This structure usually uses rotation, sliding or telescoping mechanisms to achieve the movement of the feeder to adapt to different installation positions and radio environments. The connection ports are usually designed as rotary joints or plug-and-play interfaces for easy installation and maintenance.

[0004] The current radio antenna feeder connection structures have certain inconveniences in actual use. For example, the adjustment process is cumbersome, the connection stability is insufficient, and it is not easy to quickly disassemble and assemble. These deficiencies not only increase the operation difficulty for users, but also may affect the stability and quality of signal transmission. Content of the Utility Model

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] At the same time, in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] See Figures 1-7, the object of the present utility model is to provide a radio antenna feeder connection structure, which includes an antenna 021, an antenna connection seat 02, a feeder connection seat 01 and an antenna feeder 03. The feeder connection seat 01 is fixedly connected inside the radio housing. One side of the feeder connection seat 01 close to the radio housing is rotatably connected to the antenna connection seat 02, and the antenna feeder 03 is installed on the feeder connection seat 01. That is: the antenna 021 is installed at one end of the antenna connection seat 02. The other end of the antenna connection seat 02 is fixedly connected to a first mounting seat 1. The first mounting seat 1 is rotatably connected to the feeder connection seat 01, and the feeder connection seat 01 is installed on the radio housing; the antenna feeder 03 is fixedly connected to the feeder connection seat 01. Both the feeder connection seat 01 and the first mounting seat 1 are made of metal. When the feeder connection seat 01 and the first mounting seat 1 rotate relative to each other, the metal material of both can reduce the friction force, making the rotation smoother and reducing frictional damage.

[0030] A through reserved hole is provided on the antenna connection seat 02, and a stud 3 is inserted into the reserved hole; the stud 3 sequentially passes through the antenna connection seat 02 and the feeder connection seat 01 and is threadedly connected to a nut 4. And there is no thread at the corresponding positions of the stud 3 and the antenna connection seat 02 and the feeder connection seat 01, and there is a thread at the corresponding position of the nut 4. Thus, after the stud 3 passes through the antenna connection seat 02 and the feeder connection seat 01, it is threadedly connected to the nut 4. While tightening, the antenna connection seat 02 and the feeder connection seat 01 between the two can be made to press against each other. When pressing against each other, the nut 4 is screwed to the threadless part, making the stud 3 and the nut 4 relatively fixedly connected.

[0031] Preferably, an installation hole 012 is provided inside the feeder connection seat 01. A second mounting seat 2 is detachably connected to the first mounting seat 1. The second mounting seat 2 is made of metal, and the detachable connection method can be bolt connection, snap connection or threaded connection. The second mounting seat 2 and the feeder connection seat 01 are in corresponding positions when they are in contact. When the second mounting seat 2 is damaged by friction, it can be disassembled and replaced. A tooth column 22 is fixedly connected to the second mounting seat 2. The tooth column 22 is made of plastic; it is inserted into the tooth column 22; a plurality of toothless parts 221 are evenly annularly arranged at one end of the tooth column 22 away from the second mounting seat 2, and a clamping tooth 013 is annularly arranged inside the installation hole 012. The clamping tooth 013 is arranged in cooperation with the toothless part 221 on the tooth column 22. When the feeder connection seat 01 rotates to a certain angle each time, a toothless part 221 will be in cooperation and clamped with the clamping tooth 013.

[0032] Preferably, a clamping block 21 is provided on one side of the second mounting base 2 close to the feeder connection base 01, and a clamping groove 011 cooperating with the clamping block 21 is provided on one side of the feeder connection base 01 close to the second mounting base 2. The clamping groove 011 is "C"-shaped, and the clamping block 21 is embedded inside the clamping groove 011. When the antenna rotates, the clamping block 21 will slide inside the clamping groove 011. This prevents the wires from being twisted due to the antenna rotating in a full circle, causing damage to the wires.

[0033] Preferably, a gasket 41 is installed between the nut 4 and the feeder connection base 01. The gasket 41 is a smooth metal flat gasket with both sides being smooth. The smooth metal flat gasket on both sides has a certain hardness and can reduce the friction between the nut 4 and the feeder connection base 01. When relative sliding occurs between the two, the gasket 41 can play a protective role and prevent wear.

[0034] Preferably, a nameplate 11 is installed at the bottom of the first mounting base 1.

[0035] In summary, during actual installation of the device, the feeder connection base 01 is fixedly connected inside the radio housing. Corresponding reserved holes corresponding to the mounting holes 012 and the clamping grooves 011 are provided on the radio housing. The antenna connection base 02 is abutted at the corresponding position, and the stud 3 and the nut 4 are used to connect the two. Thus, the antenna connection base 02 is provided outside the radio housing and can rotate. During actual use, every time it rotates a certain angle, the tooth 013 will be engaged with the toothless part 221, playing a role in preventing the antenna from rotating by itself. Thus, the device can realize rapid rotation adjustment of the antenna. It not only has reliable connection, but also can be easily disassembled and quickly assembled and disassembled; it not only reduces the operation difficulty of the user, but also does not affect the stability and quality of signal transmission.

[0036] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
