The copper integrated waveguide has relatively small signal loss in microwave transmission due to the high electrical conductivity of copper, and is widely used in high-quality transmission occasions. Common shapes of integrated waveguides include circular and rectangular shapes.

[0011] Preferably, the support part includes a threaded sleeve fixedly connected to the surface of the collar, a threaded rod threadedly connected to the inner wall of the threaded sleeve, and a support ring fixedly connected to the lower end of the threaded rod. Through the above components, when the support part is providing support, the threaded rod can be rotated in the threaded sleeve, and the threaded rod drives the support ring to adjust and then provide support.

[0012] Preferably, a compression pad is fixedly connected to the inner wall of the collar. After the collar is fitted onto the first waveguide and the second waveguide using the above-mentioned components, the compression pad will be compressed, thereby ensuring the overall stability of the fitting and reducing damage to the first waveguide and the second waveguide.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an integrated waveguide for microwave transmission, including a first waveguide 1 and a second waveguide 2, the second waveguide 2 being disposed on one side of the first waveguide 1, and a connecting device 3 being disposed on the surface of the first waveguide 1.

[0024] Specifically, the connecting device 3 includes a fixing ring 31, which is fixedly connected to the surface of the first waveguide 1. Four stabilizing rods 32 are fixedly connected to the surface of the fixing ring 31. A positioning ring 35 is fixedly connected to the surface of the second waveguide 2. A locking member 34 is rotatably connected to the inner wall of the positioning ring 35. A groove 37 is opened on the surface of the locking member 34. The stabilizing rods 32 are inserted into the inner wall of the positioning ring 35. A slot 33 is opened on the surface of the stabilizing rods 32. The locking member 34 is engaged with the inner wall of the slot 33. A reset component is provided between the locking member 34 and the positioning ring 35. A pushing part 36 is opened on the surface of the locking member 34.

[0025] In this embodiment: When in use, the connecting pipes of the first waveguide 1 and the second waveguide 2 can be aligned first. Then, the stabilizing rod 32 can be inserted into the inner wall of the positioning ring 35. The pushing part 36 can control the locking piece 34, thereby cooperating with the reset component to lock the locking piece 34 into the slot 33 on the surface of the stabilizing rod 32 to achieve connection. When disassembling, simply rotate the locking piece 34 to align the slot 37 with the stabilizing rod 32. The locking piece 34 will then lose its restraint on the slot 33 on the surface of the stabilizing rod 32, and can be disassembled. The overall connection is more convenient and faster.

[0026] Specifically, there are four grooves 361 on the surface of the card 34, and the four grooves 361 are arranged in a semi-circle.

[0027] Specifically, the pushing part 36 includes a groove 361 formed on the surface of the card 34. There are three grooves 361, and multiple anti-slip balls 362 are fixedly connected to the inner wall of the groove 361. The multiple anti-slip balls 362 are arranged at equal intervals.

[0028] In this embodiment: when pushing the card 34, the rotation of the card 34 can be controlled by the groove 361 in conjunction with the anti-slip ball 362, thereby improving the overall ease of use.

[0029] Specifically, the reset assembly includes four positioning rods 38 that are fixedly connected to the surface of the locking piece 34. The inner wall of the positioning ring 35 is provided with a positioning groove 310. The positioning rods 38 are slidably connected to the inner wall of the positioning groove 310. A spring 39 is fixedly connected to the side of the positioning rod 38 corresponding to the inner wall of the positioning groove 310. When the locking piece 34 rotates, the positioning rods 38 can move in the positioning groove 310, thereby playing a guiding and positioning role, ensuring that the groove 37 can be accurately moved to the stabilizing rod 32. The spring 39 can control the locking piece 34 to reset, improving the stability of the locking piece 34 in the locking groove 33 of the stabilizing rod 32.

[0030] Specifically, both the first waveguide 1 and the second waveguide 2 are provided with a support component 4. The support component 4 includes two collars 41 that are sleeved and connected to the first waveguide 1 and the second waveguide 2. The lower surface of the collars 41 is provided with a support portion 43.

[0031] In this embodiment: When in use, the two collars 41 can be respectively fitted onto the first waveguide 1 and the second waveguide 2, and supported by the support part 43.

[0032] Specifically, the support part 43 includes a threaded sleeve 431 fixedly connected to the surface of the collar 41, a threaded rod 432 threadedly connected to the inner wall of the threaded sleeve 431, and a support ring 433 fixedly connected to the lower end of the threaded rod 432.

[0033] In this embodiment: when the support part 43 is providing support, the threaded rod 432 can be rotated in the threaded sleeve 431, and the threaded rod 432 drives the support ring 433 to adjust and then provide support.

[0034] Specifically, the inner wall of the collar 41 is fixedly connected to a compression pad 42. After the collar 41 is fitted onto the first waveguide 1 and the second waveguide 2, the compression pad 42 will be compressed, thereby ensuring the overall stability of the fitting and reducing damage to the first waveguide 1 and the second waveguide 2.

[0035] Working principle: When connecting the first waveguide 1 and the second waveguide 2, the connecting ends of the first waveguide 1 and the second waveguide 2 can be aligned first. Then, the locking piece 34 is pushed to rotate by the groove 361 and the anti-slip ball 362. The locking piece 34 drives the positioning rod 38 to move in the positioning groove 310. The spring 39 is stressed. Then, the stabilizing rod 32 is inserted into the positioning ring 35. The stabilizing rod 32 passes through the semi-circular groove 37 on the surface of the locking piece 34. When the positioning ring 35 is in contact with the fixing ring 31, the pushing part 36 is released. The spring 39 releases its elastic force, which can drive the positioning rod 38 to rotate. 8 and the locking piece 34 are reset. After reset, the locking piece 34 can be inserted into the slot 33 on the surface of the stabilizing rod 32 to achieve positioning, thereby completing the connection. The overall assembly and disassembly are more convenient. After the connection is completed, the two collars 41 can be respectively fitted onto the first waveguide 1 and the second waveguide 2. The compression pad 42 will be compressed, thereby ensuring the stability of the overall fitting and reducing damage to the first waveguide 1 and the second waveguide 2. Rotate the threaded rod 432 in the threaded sleeve 431. The threaded rod 432 drives the support ring 433 to adjust and then provide support, thus completing the use.
