Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of description and clarity, and are not used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0025] Referring to Figures 1-6 , a novel composite diode structure includes a hard insulating shell 1 and two pins 2. An epoxy resin layer 3 is provided inside the hard insulating shell 1. Sockets 4 for inserting the pins 2 are opened on the left and right side walls of the hard insulating shell 1. Threaded ports 5 corresponding to the positions of the sockets 4 are opened on the left and right side walls of the epoxy resin layer 3. Threaded portions matching the inner wall threads of the threaded ports 5 are provided on the surface of the pins 2. The two pins 2 respectively pass through the two sockets 4 and are respectively threadedly installed in the two threaded ports 5;

[0026] U-shaped mounting grooves 6 are symmetrically and vertically opened on the upper surface of the hard insulating shell 1. Mounting openings are symmetrically opened on the left and right side walls of the hard insulating shell 1. Multiple mounting openings are respectively communicated with the two mounting grooves 6. A hollow rod 7 with a closed end design at one end is horizontally slidably inserted in the mounting openings. A suction cup 8 is fixedly installed at the open end of the hollow rod 7. A mounting plate 9 is fixedly sleeved on the pin 2. A mounting ring 10 is fixedly sleeved on the hollow rod 7. An L-shaped connecting rod 11 is fixedly installed on the outer wall of the mounting ring 10. A support rod is fixedly installed on the upper surface of the connecting rod 11. Two support rods are fixedly installed at the top ends; a moving plate 12 is fixedly installed.

[0027] After the two pins 2 are respectively threadedly installed in the two threaded ports 5, at this time, the multiple suction cups 8 will also correspond to the positions of the two mounting plates 9 respectively. Then, by controlling the two moving plates 12 to move horizontally away from each other, the multiple suction cups 8 will respectively abut tightly against the two mounting plates 9. Under the action of the pressing force, the suction cups 8 will deform, and the gas located inside the suction cups 8 will escape from the gap between its contact surface with the mounting plate 9, thereby completing the adsorption to the mounting plate 9, which can play a role in restricting the rotation of the mounting plate 9 and the pin 2, avoiding the self-rotation of the threaded connection under the influence of external force, and improving the connection stability of the pin 2.

[0028] A silicone cushion layer 13 is provided in the socket 4, and the diameter of the silicone cushion layer 13 is smaller than the diameter of the mounting plate 9.

[0029] The closed end of the hollow rod 7 is provided with a rotating port, and a rotating shaft 14 is hermetically and rotatably installed in the rotating port. An arc-shaped port 15 is provided on the surface of the hollow rod 7. One end of the rotating shaft 14 located inside the hollow rod 7 is fixedly installed with an arc-shaped plate 16 for covering the arc-shaped port 15 through a connecting rod. The two rotating shafts 14 are controlled to rotate together through a transmission component. The transmission component includes two gears 17 respectively fixedly installed at the ends of the two rotating shafts 14 and two rack bars 18 respectively meshed with the two gears 17. The rack bars 18 are connected to the moving plate 12 through a mounting component. The mounting component includes a vertical rod 19 fixedly installed on the upper surface of the rack bar 18. Two through holes are symmetrically provided on the surface of the moving plate 12. The two vertical rods 19 are respectively slidably inserted into the two through holes. The tops of the two vertical rods 19 are fixedly installed with a mounting plate 20. The vertical rod 19 is connected to the moving plate 12 through a telescopic component. The telescopic component includes a telescopic spring 21 sleeved on the vertical rod 19. The two ends of the telescopic spring 21 are respectively fixedly connected to the moving plate 12 and the mounting plate 20.

[0030] When it is necessary to release the adsorption of the suction cup 8, only need to control the two mounting plates 20 to move down together. At this time, the multiple rack bars 18 will move down together, and the multiple gears 17 respectively meshed with the multiple rack bars 18 will drive the multiple rotating shafts 14 to rotate, so that the multiple arc-shaped plates 16 will all rotate to no longer cover the arc-shaped port 15. At this time, the gas located outside will enter the hollow rod 7 from the arc-shaped port 15, thereby releasing the adsorption of the suction cup 8 to the mounting plate 9, which is convenient and fast. When the mounting plate 20 is released, at this time, the mounting plate 20 and the rack bar 18 will quickly move up and reset under the elastic potential energy of the telescopic spring 21, and the rotating shaft 14 and the arc-shaped plate 16 will also rotate and reset, and the arc-shaped plate 16 will cover the arc-shaped port 15 again, making it in a closed state.

[0031] In the present utility model, after two pins 2 are respectively threadedly installed in two threaded ports 5, at this time, multiple suction cups 8 will also respectively correspond to the positions of two mounting plates 9. Then, by controlling two moving plates 12 to move horizontally away from each other, the multiple suction cups 8 are respectively tightly abutted against the two mounting plates 9. Under the action of the pressing force, the suction cups 8 will deform, and the gas in the suction cups 8 will escape from the gap between its contact surface with the mounting plate 9, thus completing the adsorption with the mounting plate 9, which can play the role of restricting the rotation of the mounting plate 9 and the pins 2, avoiding the self-rotation of the threaded connection under the influence of external force, and improving the connection stability of the pins 2.

[0032] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "fixation" and the like shall be understood in a broad sense.

[0033] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
