[0024] See also Figure 1-Figure 5 The aviation plug connection structure includes a socket 1 and a plug 2. The socket 1 and the plug 2 are connected in a socket-and-socket manner.

[0026] A sliding rod 12 is fixedly connected to the end of the inner cavity 8 away from the interface, and the radial cross-section of the sliding rod 12 is rectangular. A sliding sleeve 7 is slidably connected to the rod body of the sliding rod 12. A through hole is provided at the top of the slot 3 to cooperate with the sliding sleeve 7 for sliding connection.

The return spring 13 is sleeved on the lower part of the rod body of the sliding rod 12, and the two ends of the sliding rod 12 are in close contact with the bottom wall of the inner cavity 8 and the bottom end of the limiting ring 9 respectively.
[0027] The return spring 13 provides elastic force to apply a constant upward force to the sliding sleeve 7, and cooperates with the top wall of the inner cavity 8 to limit the pressing block 10, so that the sliding sleeve 7 is always at the top position of the sliding rod 12 in the initial state, and extends out of the top of the card seat 4 for easy pressing.
[0028] A sleeve rod 14 is vertically fixedly connected to the center of the temporal part of the inner cavity 8, and a first clamping arm 15 and a second clamping arm 16 are rotatably connected to the rod body of the sleeve rod 14; a first sleeve ring 17 is fixedly connected to one end of the first clamping arm 15, and the first clamping arm 15 is rotatably connected to the sleeve rod 14 through the first sleeve ring 17, and a first push plate 19 is fixedly connected to the end of the first sleeve ring 17 away from the first clamping arm 15; a second sleeve ring 18 is fixedly connected to one end of the second clamping arm 16, and the second clamping arm 16 is rotatably connected to the sleeve rod 14 through the second sleeve ring 18, and a second push plate 20 is fixedly connected to the end of the second sleeve ring 18 away from the second clamping arm 16; The first push plate 19 and the second push plate 20 are rectangular block structures, and are provided with notches on the first push plate 19 and the second push plate 20 to avoid obstruction to the rotation of the first clamp arm 15 and the second clamp arm 16, so as to avoid the first sleeve ring 17 and the second sleeve ring 18, and the first push plate 19 and the second push plate 20 are respectively fixedly connected with the first sleeve ring 17 and the second sleeve ring 18 in a centrally symmetrical offset manner, and the first push plate 19 and the second push plate 20 cooperate with each other to form a linear slideway, and the pressure block 10 is slidably connected with the linear slideway, and the sliding connection of the first sleeve ring 17 and the second sleeve ring 18 on the rod body of the sleeve rod 14 is distributed up and down.
[0029] With the sleeve rod 14 as a fulcrum, the first clamp arm 15 and the second clamp arm 16 cooperate with each other to form a clamping structure, and a straight slide formed by the combination of the first push plate 19 and the second push plate 20 is provided on the side away from the clamping end to cooperate with the pressure block 10 to slide and push away, thereby realizing the clamping function of the holding mechanism.
[0030] The first clamp arm 15 and the second clamp arm 16 are both L-shaped block structures, and the two clamp arm L-shaped structures cooperate with each other to form a rectangular cavity. The two clamp arms are vertically fixedly connected to the side wall on one side close to the rectangular cavity with a positioning column 21, and a limit spring 11 is provided in the middle of the two positioning columns 21, and the two ends of the limit spring 11 are respectively sleeved on the column bodies of the two positioning columns 21; there are two wedge blocks 6, and the two wedge blocks 6 are respectively fixedly connected to the side wall of the two clamp arms away from the rectangular cavity; there are two slots 5, and the two slots 5 are symmetrically located on both sides of the inner wall of the slot 3, and the side wall of the base 4 is provided with sliding holes that cooperate with the sliding connection of the two prime wedge blocks 6.
[0031] The limit spring 11 provides elastic force to push the first clamp arm 15 and the second clamp arm 16 , so that the two clamp arms are always subjected to a separating force, thereby causing the two wedge blocks 6 to slide outwards and protrude from the side wall of the holder 4 .
[0032] In actual use, when connection is required, the socket 1 and the plug 2 are pushed toward each other after alignment through the structural features of the card slot 3 and the card seat 4. When the wedge-shaped blocks 6 protruding on both sides of the card seat 4 contact the side walls of the card slot 3, due to the inclined structure of the wedge-shaped blocks 6, they automatically shrink inward until they are pushed to the position of the slot 5. Under the elastic force of the limit spring 11, the letter "" pops up to complete the connection; when disconnection is required, both hands hold the socket 1 and the plug 2 respectively, and the thumb of the hand holding the plug 2 presses the top of the sliding sleeve 7 and applies downward pressure to resist the reset spring The elastic force 13 drives the sliding sleeve 7 to drive the pressure block 10 to move downward, and the pressure block 10 slides in the linear slideway formed by the first push plate 19 and the second push plate 20. Due to the elliptical radial cross-sectional structure of the pressure block 10, the first push plate 19 and the second push plate 20 are pushed to deviate to both sides while sliding. Under the support of the two rings, the first clamp arm 15 and the second clamp arm 16 approach each other against the elastic force of the limit spring 11. At this time, the wedge blocks 6 on both sides are contracted inward, thereby disengaging from the slot 5, and finally disconnecting the socket connection between the socket 1 and the plug 2.
[0033] In summary: the aviation plug connection structure realizes the automatic pop-up of the wedge block 6 through the mutual cooperation of the sliding sleeve 7, the pressure block 10, the first clamp arm 15, the second clamp arm 16, the limit spring 11 and the return spring 13, and cooperates with the limit of the slot 5 to axially limit the connection of the aviation plug 2 to avoid loose connection, and the plug-in and unplug operations are convenient and quick, and are suitable for operation in a small space.
