[0033] The top and bottom of the sheath 5 are both slidably connected with mounting rods 6, and a spring 7 is sleeved and installed at the connection between the mounting rod 6 and the sheath 5. The ends of the mounting rods 6 that are close to each other are fixedly connected with an inclined wedge block 8, and the inclined wedge block 8 passes through the sheath 5. The ends of the mounting rods 6 that are far away from each other are fixedly connected with a dial head 9;

[0034] The outer surface of the male connector 3 is in contact with the oblique wedge 8, the sheath 5 is movably sleeved with the male connector 3, and the male connector 3 is movably sleeved with the female connector 4. The oblique wedge 8 is used to prevent the male connector 3 from being separated from between the sheath 5 and the female connector 4.

[0035] An inner hole 10 is provided at the axis center of the female connector 4, and an outer ring body 11 is fixedly mounted on the surface of the female connector 4;

[0036] The male connector 3 and the sheath 5 are both provided with an outwardly convex bevel ring on one side, which is used to facilitate mutual clamping and locking;

[0037] In this embodiment, during installation, when the male connector 3 has just passed the inclined wedge block 8, the male connector 3 can still continue to move forward, but the male connector 3 cannot return without pushing the dial head 9 outward;

[0038] See also Figures 4 to 6 , a technical solution of an embodiment of the present invention: the surface of the female connector 4 is symmetrically provided with an oblique cut 12, a guide groove 13 is penetrated through the oblique cut 12, a slider 15 is slidably connected in the guide groove 13, and a semi-ring body 16 is fixedly connected to the surface of the slider 15;

[0039] The outer surface of the inner hole 10 is fixedly connected with a mounting block 14, and a cable for connecting the transmission line 1 and the inner hole 10 is arranged in the mounting block 14;

[0041] A slip ring 18 is slidably connected to the female joint 4, and push rods 19 are symmetrically installed on the top and bottom of the slip ring 18. A spring 20 is sleeved and installed at the connection between the slip ring 18 and the female joint 4;

[0042] The female joint 4 is also provided with a U-shaped rod 21, the bottom of the U-shaped rod 21 is hinged with a pressing plate 22, the pressing plate 22 is rotatably connected to the female joint 4, and a torsion spring 23 is installed at the connection between the pressing plate 22 and the U-shaped rod 21;

[0043] A baffle 24 is fixedly mounted on one side of the pressing plate 22 close to the U-shaped rod 21, and the push rod 19 abuts against the U-shaped rod 21. The baffle 24 is used to limit the flipping angle of the pressing plate 22 so that the push rod 19 will not cause the pressing plate 22 to flip during the return process.

[0044] An outer needle 26 is fixedly connected to the axis of the male connector 3;

[0045] In this embodiment, when unlocking, the slip ring 18 drives the push rod 19 to return to its original position, which in turn drives the U-shaped rod 21 to rotate in the opposite direction and triggers the torsion spring 23 to twist. During this process, the pressure plate 22 will not swing in the opposite direction. After the push passes through the U-shaped rod 21, the torsion spring 23 drives the U-shaped rod 21 to return to its original position automatically.

[0046] In this embodiment, the two half ring bodies 16 are joined together to form a circular ring with an inclined arc on the inner surface, which facilitates smooth contact with the end of the outer needle 26 and plays a guiding role;

[0047] See also Figures 7 and 8 , a technical solution of an embodiment of the present invention: a buckle strip 27 is hingedly connected to one end of the male connector 3 close to the transmission line 1, one end of the buckle strip 27 is connected to a spring 28, and the end of the buckle strip 27 away from the spring 28 is movably connected to the sheath 5;

[0048] The end of the male connector 3 close to the transmission line 1 is rotatably connected to an unlocking ring 29, and the inner surface of the unlocking ring 29 is fixedly connected to an arc strip 30, and the inner surface of the arc strip 30 abuts against one end of the buckle strip 27;

[0049] In this embodiment, in the initial state, the buckle strip 27 is in an inclined state. After being locked with the sheath 5, the buckle strip 27 is in a slightly horizontal state. During the unlocking process, the buckle strip 27 is inclined toward the other end, and the end in contact with the sheath 5 is tilted.

[0050] The use method and advantages of the present invention: The high-frequency transmission line connection device for unmanned vehicles has the following working process:

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0052] S1: When connecting, the operator holds the transmission line 1 and the transmission line 2 respectively, and places the male connector 3 opposite to the female connector 4, so that the male connector 3 is inserted into the gap between the sheath 5 and the female connector 4. When the end of the male connector 3 enters the sheath 5, it contacts the upper and lower inclined wedge blocks 8, and pushes the inclined wedge blocks 8 to compress the spring 1 7. When the end of the male connector 3 passes the inclined wedge blocks 8, the spring 1 7 returns to its original position so that the male connector 3 is limited in the sheath 5, which is convenient and quick to connect during operation;

[0053] S2: As the male connector 3 continues to be pushed inward, the end face of the male connector 3 is in contact with the slip ring 18 and pushes the slip ring 18 forward. During this process, the spring 20 is gradually compressed. At this time, the outer needle 26 in the male connector 3 approaches the inner hole 10. When the push rod 19 contacts the U-shaped rod 21, the U-shaped rod 21 is pushed to rotate. Through the baffle 24, the pressure plate 22 is pushed downward to flip, so that the guide plate 17 moves downward and the spring 3 25 is compressed. During this process, the slider 15 sliding in the guide plate 17 extends outward along the guide groove 13 and moves along the guide groove 13. The guide groove 13 slides, driving the semi-ring body 16 to wrap the outer ring body 11, and the two semi-ring bodies 16 form a circle. When the outer needle 26 approaches the inner hole 10, the angle of the outer needle 26 is corrected, so that the outer needle 26 is axially aligned with the inner hole 10, so that the outer needle 26 can be smoothly inserted into the inner hole 10. When the tip of the outer needle 26 enters the inner hole 10, the push rod 19 is disconnected from the U-shaped rod 21, and the guide plate 17 returns to its original position, so that the semi-ring body 16 is retracted and enters the inside of the oblique cut 12, and the slip ring 18 continues to be pushed forward by the male connector 3;

[0054] S3: When the slip ring 18 slides to the end, the buckle strip 27 set on the outer surface of the male connector 3 contacts the surface of the sheath 5, and follows the inclined surface of the sheath 5 so that the buckle strip 27 buckles the sheath 5. At this time, the buckle strip 27 changes from an inclined state to a horizontal state, and compresses the spring four 28 for a distance. The outer needle 26 and the inner hole 10 are docked, the male connector 3 and the female connector 4 are docked and locked, and the transmission line 1 and the transmission line 2 are connected. When the transmission line needs to be disconnected, the operator rotates the unlocking ring 29 to make the arc strip 30 set corresponding to the buckle strip 27 press down one end of the buckle strip 27, so that the end of the buckle strip 27 that contacts the sheath 5 is tilted, and then the spring two 20 is quickly released, so that the transmission line two 2 and the female connector 4 are quickly ejected, and the inner hole 10 and the outer needle 26 are quickly disconnected.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention.
