[0002] Aviation plug is a type of connector. It originated from the military industry, hence the name, also known as aviation plug. Aviation plug is an electromechanical component that connects electrical circuits. Therefore, its own electrical parameters are the first thing to consider when selecting an aviation plug. Correct selection and use of aviation plugs is an important aspect of ensuring circuit reliability.

[0003] Chinese utility model patent CN214542750U discloses a multifunctional adjustable aviation plug, including: a conversion head and a connector, the left side of the conversion head is provided with multiple energized contact rods, the right end of the conversion head is rotatably connected to an output connection block, the right end of the output connection block is provided with multiple energized sleeve rods, the upper and lower sides of the connector are respectively rotatably connected to pressing plates, the left sides of the two pressing plates are respectively fixedly connected to a card block, the right sides of the two pressing plates are respectively fixedly connected to a spring, the right side of the connector is fixedly connected to two fixed plates, and an adjustment rod is rotatably connected between the two fixed plates.

[0004] In the above technical solution, an upward thrust is generated on the pressing plate by the spring, so that the left end of the pressing plate moves downward. The downward movement of the left end of the pressing plate causes the clamping block to move downward, and the fitting of the clamping block and the clamping slot prevents the connector and the conversion head from falling off. However, the fitting of the clamping block and the clamping slot by the upward force of the spring has poor stability, which can easily lead to unstable connection between the connector and the conversion head. Utility Model Content

[0006] In view of this, the utility model provides an adjustable aviation plug, comprising: a conversion head and a connecting head, wherein the left end of the conversion head is provided with a plurality of energized contact rods, the right end of the conversion head is rotatably connected to a connecting cylinder, and the right end of the connecting cylinder is provided with a plurality of energized sleeves, and is characterized in that the outer wall of the connecting cylinder near one end of the connecting cylinder is provided with four sliding grooves in the circumference, and a first tooth plate is provided in the upper and lower sliding grooves, and a pull rod is symmetrically installed on the upper and lower ends of the connecting head, and one end of the pull rod passes through the connecting head and is connected to the second tooth plate, and the first tooth plate is meshed with the second tooth plate.

[0007] In the above technical solution, further, a reset spring is sleeved on the outer wall of the pull rod, one end of the reset spring is fixedly connected to the inner wall of the connector, and the other end of the reset spring is fixedly connected to the upper surface of the second tooth plate.

[0008] In the above technical solution, further, a fixing block adapted to the left and right sliding grooves is provided at the left end of the connector.

[0009] In the above technical solution, further, the right end of the connector is fixedly connected to two fixing plates, a connecting rod is connected between the two fixing plates by rotating a knob, and an electric wire is provided at one end of the connecting rod away from the connector.

[0010] In the above technical solution, further, a rotation groove is provided at the right end of the conversion head, and the connecting tube is movably sleeved in the rotation groove at one end close to the conversion head.

[0011] In the above technical solution, further, a plurality of balls are provided on the outer wall of the connecting cylinder located in the conversion head, and the plurality of balls are rotatably connected to the inside of the rotating groove.

[0012] The beneficial effect of the present invention is that before the connecting tube is inserted into the interior of the connecting head, the pull rods at the upper and lower ends of the connecting head are pulled outward, thereby driving the second tooth plate to move upward, and then the connecting tube is inserted into the interior of the connecting head, and the pull rod is released. Under the action of the reset spring, the second tooth plate enters the slide groove and is engaged with the first tooth plate, thereby achieving a stable connection between the connecting head and the conversion head.
