[0002] A walkie-talkie, also known as a two-way radio, is a portable device capable of two-way communication, allowing users to conduct point-to-point or point-to-multipoint communications within a certain distance. Walkie-talkies are widely used in public security, civil aviation, transportation, water conservancy, railways, manufacturing, construction, services and other industries for communication and command and dispatch between group members, improving communication efficiency and the ability to respond quickly to emergencies.

[0003] After searching, the existing patent number CN218123913U discloses an audio connector device for a walkie-talkie. The patent provides an audio connector device for a walkie-talkie with a switching and adaptation function, which is convenient for connecting the walkie-talkie with ordinary headphones, thereby being easy to use and saving costs. However, the audio connector can only connect and convert walkie-talkies of a specific brand or the same size of audio sockets. When it is necessary to convert walkie-talkies of different brands or audio socket sizes, the corresponding audio connector needs to be replaced, which reduces the application range of the device, and therefore needs to be improved.

The bottom end of the first round rod 10 passes through the No. 2 rectangular plate 9 and the No. 1 rectangular plate 8 in sequence and extends to the bottom of the No. 1 rectangular plate 8.

[0025] When the first round rod 10 is rotated, the semicircular plate 11 will rotate. When the semicircular plate 11 rotates to the left, the fixing effect on the second rectangular plate 9 and the rotating plate 4 will be released.

[0026] Among them, the outer surface of the first round rod 10 is movably connected to the No. 1 spring 12, the top of the No. 1 spring 12 is fixedly connected to the bottom of the No. 1 rectangular plate 8, and the bottom end of the No. 1 spring 12 is fixedly connected to the outer surface of the first round rod 10.

[0027] Due to the design of the No. 1 spring 12, the first round rod 10 has a good reset function.

[0028] Among them, the right side of the fixing frame 3 is fixedly connected to the audio cable 13, the other end of the audio cable 13 is fixedly connected to the conversion socket 14, the top of the conversion socket 14 is movably connected to the baffle 15, and the inside of the baffle 15 is movably sleeved with a rotating rod 16.

[0029] When the baffle 15 rotates, the rotating rod 16 will be driven to rotate.

[0030] The other end of the rotating rod 16 passes through the conversion socket 14 and extends to the outside of the conversion socket 14 and is movably connected to the inside of the conversion socket 14. The right end of the rotating rod 16 is fixedly connected to a gear 17. A vertical slot 20 is opened on the right side of the conversion socket 14.

[0031] When the gear 17 rotates, it drives the rotating rod 16 to rotate together.

[0032] The outer surface of the gear 17 is meshed with a tooth plate 18 , and the bottom end of the tooth plate 18 is fixedly connected to a moving block 19 . The outer surface of the moving block 19 is movably connected to the inside of the vertical slot 20 .

[0033] When the moving block 19 moves, it drives the tooth plate 18 to move vertically up and down under the limiting action of the vertical slot 20.

[0036] The working principle and use process of this utility model:

[0037] First, when the audio connector needs to be used, pushing the push rod 22 will cause the moving block 19 to drive the tooth plate 18 to move vertically upward under the limiting action of the vertical slot 20, and cause the gear 17 to drive the rotating rod 16 to rotate, thereby causing the baffle 15 to rotate. At this time, the sealing effect on the top of the conversion socket 14 will be released, making it convenient for the operator to use the conversion socket 14 normally, and realizing the sealing effect on the top of the conversion socket 14 when the conversion socket 14 is idle, thereby preventing dust and water vapor from entering the interior of the conversion socket 14 and affecting the service life of the conversion socket 14.

[0038] When it is necessary to convert audio between walkie-talkies of different brands, and the size of the conversion plug 2 in the device does not match, and the conversion plug 2 needs to be replaced, first rotate the first round rod 10 to make the semicircular plate 11 rotate to the left. At this time, under the elastic force of the No. 1 spring 12, the semicircular plate 11 will be separated from the inside of the No. 2 rectangular plate 9 and the No. 1 rectangular plate 8, and the fixing effect on the No. 2 rectangular plate 9 and the rotating plate 4 will be released. Then, the rotating plate 4 is rotated to make the two connecting rods 5 move, so that the two connecting rods 5 drive the two clamping plates 6 to move horizontally opposite to each other under the limiting action of the limit rod 7, thereby releasing the fixing effect on the conversion plug 2, realizing the function of facilitating the disassembly and assembly of the conversion plug 2, improving the application range of the device, and reducing the labor intensity of the operator.
