It should be understood that the specific embodiments described herein are part of the embodiments of the utility model, not all embodiments, and are only used to explain the embodiments of the utility model, and do not limit the embodiments of the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] Please refer to Figures 1-5 The utility model provides a technical scheme: an adjustable waveguide coaxial converter, including waveguide coaxial converter body 1, the surface of waveguide coaxial converter body 1 is equipped with connector 2, the one end of connector 2 away from waveguide coaxial converter body 1 is fixed with screw joint 3, the outside of connector 2 is equipped with protective sleeve 4, and protective sleeve 4 is fixed on the surface of waveguide coaxial converter body 1, and the outer ring surface of protective sleeve 4 is screwed with clamping screw rod 8, and the one end of protective sleeve 4 away from waveguide coaxial converter body 1 is equipped with reserved slot 5, and reserved slot 5 is annular groove, and the circular arc surface of reserved slot 5 is equipped with installation groove 6, and installation groove 6 is circular groove, and the two parallel distribution side walls between installation groove 6 are fixed with rubber ring one 7, and clamping screw rod 8 is equipped with multiple, and multiple clamping screw rod 8 is arranged around protective sleeve 4, and one end of clamping screw rod 8 is against the outer ring surface of rubber ring one 7. After the connector of transmission line is sleeved on connector 2, the transmission line connector is screwed on screw joint 3, and the connecting place of connector and connector 2 is protected by protective sleeve 4, so that the swing phenomenon of connector is avoided, and clamping screw rod 8 is screwed to the inside of protective sleeve 4, and rubber ring one 7 is stretched during the advancing of clamping screw rod 8, and until rubber ring one 7 is clamped between transmission line connector and clamping screw rod 8, the connection of transmission line connector and connector 2 is reinforced.

[0020] The inside of protective sleeve 4 is equipped with waterproof cover 10, one end of waterproof cover 10 is fixed with rubber ring two 11, the surface of reserved slot 5 is equipped with storage groove 9, and storage groove 9 is annular groove, and one end of waterproof cover 10 is fixed in the inside of storage groove 9, and the length of the pipe of waterproof cover 10 is greater than the length of the pipe of protective sleeve 4;The surface of reserved slot 5 is fixed with limit ring 12, and limit ring 12 is circular plate with " C " shaped section, and after waterproof cover 10 is stored in storage groove 9, rubber ring two 11 is sleeved in limit ring 12. When transmission line connector and connector 2 are connected, before clamping screw rod 8 is screwed to clamp transmission line connector, first, waterproof cover 10 is unfolded, that is, rubber ring two 11 drives waterproof cover 10 to unfold and be sleeved on the connecting place of transmission line structure and connector 2, and then clamping screw rod 8 is operated to clamp transmission line connector and reinforce connection.
