It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: a dual-directional coupler for microwave ferrite, the dual-directional coupler for microwave ferrite comprising: a coupler body 1, an output terminal 2 and a mounting ring 3 are arranged on the side of the coupler body 1, a thread groove 4 is provided on the end face of the mounting ring 3, a connecting pipe 5 is sleeved on the surface of the output terminal 2, a second thread groove 6 is provided on the end face of the connecting pipe 5, and a positioning ring 7 can be screwed in the second thread groove 6;

[0032] A traction frame 8, a fixing plate 9 is sleeved on the surface of the traction frame 8, and a limiting plate 10 and a positioning plate 11 are arranged inside the fixing plate 9;

[0033] When it is necessary to quickly connect the device connector to the coupler body 1 during use, the traction frame 8 can be used to guide the device connector to be inserted into the output end 2 of the coupler body 1. The horn-shaped structure at one end of the traction frame 8 can be used to conveniently guide the device connector, so that the connector can be conveniently connected to the coupler body 1. The length of the output end 2 of the coupler body 1 can be adjusted by the cooperation of the connecting tube 5 and the positioning ring 7, and the cooperation of the positioning ring 7 and the output end 2, so as to facilitate the length adjustment of the output end 2 of the coupler body 1 for convenient connection.

[0034] Embodiment 2: On the basis of embodiment 1, in order to facilitate the adjustment of the connection length of the output end 2, a connecting tube 5 is provided. A limiting nut 12 is sleeved on the surface of the connecting tube 5. A threaded hole is provided on the surface of the connecting tube 5. A limiting bolt 13 is screwed in the threaded hole. The contact between the limiting bolt 13 and the surface of the output end 2 can be used to fix the connecting tube 5 on the surface of the output end 2. A connecting sleeve 14 is provided on the end face of the positioning ring 7. A limiting threaded hole 15 is provided on the surface of the connecting sleeve 14. One end of the limiting bolt 13 can be screwed into the limiting threaded hole 15. The outer ring surface of the positioning ring 7 is provided with threads. The positioning ring 7 can be screwed into the second thread groove 6 using the threads provided on the surface. The outer diameter and inner diameter of the connecting sleeve 14 are the same as the outer diameter and inner diameter of the output end 2. A thread is provided on one end of the surface of the output end 2. The connecting tube 5 can be screwed on the thread provided on the surface of the output end 2. The mounting ring 3 is fixedly connected to the side of the coupler body 1 by bolts. The mounting ring 3 is fixed in position so that the output end 2 is located at the center point of the surface of the mounting ring 3. The connecting tube 5 can slide along the output end 2.

[0035] When the length of the output end 2 needs to be adjusted according to the needs during use, the limiting bolt 13 can be loosened first and then the limiting nut 12 can be used to displace the connecting pipe 5 on the output end 2, so that the connecting pipe 5 is screwed on the thread opened on the surface of the output end 2, and then the positioning ring 7 can be screwed into the second thread groove 6, and the limiting bolt 13 is rotated to make one end of the limiting bolt 13 screwed into the limiting threaded hole 15 to fix the connecting sleeve 14, so that the output end 2 can be increased by a certain length with the help of the connecting pipe 5, the connecting sleeve 14 and the positioning ring 7, so that the connector can be conveniently connected to the output end 2 under special circumstances, thereby improving the convenience of using the coupler body 1.

[0036] In order to facilitate the quick alignment and connection of the joint with the output end 2 of the coupler body 1, a traction frame 8 is provided. A fixing groove 16 is provided on the outer ring surface of the mounting ring 3. The fixing groove 16 is an annular plate structure. A second thread is provided on the outer ring surface of one end of the traction frame 8. One end of the traction frame 8 can be screwed into the thread groove 4 by using the provided second thread. One end of the traction frame 8 is a trumpet-shaped structure as a whole, and the other end of the traction frame 8 is a tubular structure as a whole.

[0037] When in use, first install the traction frame 8 in the mounting ring 3. Then, when it is necessary to quickly connect the connector of the device to the output end 2 of the coupler body 1, the connector can be directly inserted into the traction frame 8. The horn-shaped setting at one end of the traction frame 8 can facilitate the traction and guidance of the connected connector, so that the connector can be quickly aligned with the output end 2 for connection, which saves time and is more convenient.

[0038] In order to improve the installation stability of the traction frame 8 and the mounting ring 3, a limit card plate 20 is set. The fixed plate 9 is an annular plate structure. The surface of the fixed plate 9 is fixedly connected with a vertical plate 17. A hole is opened on the side of the vertical plate 17. A damping bearing 18 is arranged in the hole. A rotating rod 19 is fixedly connected to the inner ring surface of the damping bearing 18. The surface of the rotating rod 19 is sleeved with a limit card plate 20. The limit card plate 20 is an "L"-shaped plate structure as a whole. One end of the limit card plate 20 can be inserted into the fixed card slot 16. Two groups of limit card plates 20 are provided, and the two groups of limit card plates 20 are symmetrically distributed about the traction frame 8.

[0039] When the traction frame 8 is connected to the mounting ring 3 during use, the limiting card plate 20 is first rotated in conjunction with the damping bearing 18 to an angle, and then the traction frame 8 can be connected to the mounting ring 3. After the connection, the limiting card plate 20 is rotated so that one end of the limiting card plate 20 is inserted into the fixed card slot 16. The setting of the damping bearing 18 can prevent the limiting card plate 20 from rotating at will and play a damping role, and also prevent the limiting card plate 20 from detaching after being inserted into the fixed card slot 16.

[0040] Embodiment 3: On the basis of embodiment 2, in order to facilitate the connection of the joint into the output end 2 and fix it, a positioning plate 11 is provided, a support rod 37 is provided on the inner side of the placement groove 31, the positioning plate 11 is sleeved on the support rod 37, the positioning plate 11 can rotate around the support rod 37, two groups of positioning plates 11 are provided, the two groups of positioning plates 11 are symmetrically distributed about the inside of the traction frame 8, the positioning plate 11 is a square plate structure, a damping pad 38 is provided on the outer surface of the positioning plate 11, the damping pad 38 is glued to the surface of the positioning plate 11, a base 39 is provided on the surface of the placement groove 31, a positioning spring 40 is provided on the surface of the base 39, one end of the positioning spring 40 is fixedly connected to the surface of the base 39, and the other end of the positioning spring 40 is fixedly connected to the surface of the positioning plate 11, and the pulley 36 provided at the other end of the limit plate 10 is in contact with the upper surface of the positioning plate 11;

[0041] During use, after the connector is connected to the output end 2 of the coupler body 1, the positioning plate 11 provided in the traction frame 8 can be used to hold the connector in place. The damping pad 38 provided on the surface of the positioning plate 11 can increase the friction with the connector surface to improve the limiting stability, and on the other hand, it can also avoid the problem of the positioning plate 11 causing wear on the surface of the equipment connector. The setting of the positioning spring 40 can facilitate the traction force of the positioning spring 40 to reset the positioning plate 11 when the positioning plate 11 is not in use, so that the positioning plate 11 can be stored in the placement slot 31 to improve the convenience of use.

[0042] In order to make it more convenient to use the positioning plate 11 to fix the joint connected to the output end 2, a limit plate 10 is provided on the side of the limit plate 10, and the limit plate 10 can be sleeved on the guide rod 32 by using the slide groove 34. The limit plate 10 can be displaced on the guide rod 32 through the slide groove 34, and the limit plate 10 can be displaced in the movable groove 30. A traction wheel 35 is provided at one end of the limit plate 10, and a pulley 36 is provided at the other end of the limit plate 10. The traction wheel 35 and the pulley 36 can be rotated with the help of external force. One end of the traction spring 33 is fixedly connected to the surface of the movable groove 30, and the other end of the traction spring 33 is fixedly connected to the side of the limit plate 10. A movable groove 30 is provided on the side of the fixed plate 9, and a placement groove 31 is provided in the traction frame 8. The placement groove 31 and the movable groove 30 are connected to each other. A guide rod 32 is provided on the inner surface of the movable groove 30, and a traction spring 33 is sleeved on the surface of the guide rod 32. The limit plate 10 is an "L"-shaped plate structure as a whole;

[0043] The traction spring 33 is set so that the limit plate 10 can be reset along the guide rod 32 when not in use, so that the limit plate 10 can be reset to the original position when not in use.

[0044] In actual use, when it is necessary to quickly connect the device connector to the coupler body 1, the setting of the traction frame 8 can be used to guide the device connector to be inserted into the output end 2 of the coupler body 1. The horn-shaped structure at one end of the traction frame 8 can be used to conveniently guide the device connector, so that the connector can be conveniently connected to the coupler body 1. The connection tube 5 and the positioning ring 7 can be used to cooperate with the positioning ring 7 and the output end 2 to adjust the length of the output end 2 of the coupler body 1, so as to facilitate the length adjustment of the output end 2 of the coupler body 1 for connection. This avoids the problem that the internal and external structures of the existing directional coupler body 1 are relatively simple, which makes it inconvenient for operators to quickly assemble and connect other device connectors with the device during use, and at the same time, when connecting the output end 2 of the coupler body 1, it is inconvenient for operators to slightly adjust the length of the output end 2 of the coupler body 1 according to usage requirements.
