Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-9As shown, the present invention provides a high-power microstrip isolator, including a housing 1 and an isolation component 110, which is installed on the inside of the housing 1.

The adjustment mechanism 2 includes a mounting frame 210, and a mounting mechanism 3 is installed on the outside of the mounting frame 210. The mounting mechanism 3 can adjust the mounting point, thereby facilitating installation and connection. A heat dissipation mechanism 4 is installed on the outside of the housing 1, so that the heat dissipation mechanism 4 can dissipate heat from the device.

[0026] The adjustment mechanism 2 includes an adjustment rod 201, and there are four adjustment rods 201. The four adjustment rods 201 are movably inserted in the shell 1. The bottom ends of the four adjustment rods 201 are fixedly connected to a fixing frame 202. The mounting frame 210 is rotatably mounted on the bottom end of the fixing frame 202. A groove 203 is opened on the outside of the adjustment rod 201.

[0027] By adopting the above technical solution, the shell 1 can slide on the adjustment rod 201, so that the height of the isolation component 110 can be adjusted, which can ensure the optimal connection between the equipment and other components, adapt to different installation environments, simplify the maintenance and debugging process, and improve the overall performance and reliability of the system.

A positioning block 205 is rotatably provided at the end of the No. 1 bolt 204. A soft pad 206 is fixed on the end of the positioning block 205 away from the No. 1 bolt 204. The soft pad 206 fits with the inner wall of the groove 203. A No. 1 rotating part 207 is fixed on the end of the No. 1 bolt 204 away from the positioning block 205.

[0029] By adopting the above technical solution, the No. 1 bolt 204 is rotated to drive the positioning block 205 to move, and the housing 1 and the adjusting rod 201 are positioned by the positioning block 205.

[0030] Two sliding grooves 211 are defined at the top of the mounting frame 210 . Sliding blocks 212 are slidably disposed in the sliding grooves 211 . A connecting plate 213 is rotatably disposed at the top of the sliding block 212 . The connecting plate 213 is rotatably connected to the fixing frame 202 at one end away from the sliding block 212 .

[0031] By adopting the above technical solution, the sliding block 212 can move in the sliding groove 211, and the angle of the fixing frame 202 can be adjusted through the connecting plate 213, so that the angle of the isolation component 110 can be adjusted, which can improve the alignment of the signal path, reduce signal reflection and loss, and thus enhance the isolation performance.

[0032] Square grooves 214 are provided on both sides of the mounting frame 210, and a No. 2 bolt 215 is fixed on the opposite side of the two sliding blocks 212. The No. 2 bolt 215 is movably inserted into the square groove 214, and a hexagonal nut 216 is threadedly sleeved on the outer side of the No. 2 bolt 215.

[0034] The mounting mechanism 3 includes a movable frame 301, which is slidably inserted at the bottom end of the mounting frame 210. A symmetrically distributed insertion rod 302 is movably inserted in the movable frame 301. A plurality of slots 303 are provided on both sides of the inner wall of the mounting frame 210. The insertion rod 302 is movably inserted in the slot 303. Fixed blocks 304 are fixed at both ends of the movable frame 301, and mounting holes 305 are provided in the fixed blocks 304.

[0035] By adopting the above technical solution, the insertion rod 302 is inserted into the slot 303, thereby completing the limiting and positioning of the movable frame 301.

[0036] The movable frame 301 is provided with an adjustment slot 310, and a threaded rod 311 is rotatably provided in the adjustment slot 310. A wedge block 312 is threadedly sleeved on the outer side of the threaded rod 311, and the wedge block 312 is movably inserted in the adjustment slot 310. A second wedge block 313 is fixedly provided at one end of the two insertion rods 302 close to the first wedge block 312, and the two second wedge blocks 313 are movably inserted in the adjustment slot 310. The two sides of the number one wedge block 312 are respectively fitted with the outer sides of the two number two wedge blocks 313, and a number two rotating part 314 is fixed at the end of the threaded rod 311.

[0037] By adopting the above technical solution, the movement of the No. 1 wedge block 312 can drive the No. 2 wedge blocks 313 on both sides to move, thereby driving the insertion rod 302 to move.

[0038] The movable frame 301 is provided with symmetrically distributed circular grooves 315, and the two insertion rods 302 are movably inserted in the two circular grooves 315 respectively. A fixed plate 316 is fixed on the outer side of the insertion rod 302, and the fixed plate 316 is movably inserted in the circular groove 315. The inner wall of the circular groove 315 and the fixed plate 316 are fixedly connected with a compression spring 317, and the insertion rod 302 is movably inserted in the compression spring 317.

[0039] By adopting the above technical solution, the compression spring 317 can push the fixed plate 316 to move toward the second wedge block 313, thereby allowing the insertion rod 302 to be disengaged from the slot 303 without being subjected to force.

[0040] The outer side of the shell 1 is fixed with external slideways 401 that are symmetrically distributed. A back panel 402 is installed on the outer side of the shell 1. Insertions 403 are fixed at both ends of the back panel 402. Mounting slots 404 are opened in the inserts 403. The mounting slots 404 are movably inserted in the inserts 403. A number 1 heat sink fin 405 is installed on the outer side of the back panel 402.

[0041] By adopting the above technical solution, the back plate 402 can be disassembled from the housing 1, and the first heat sink fin 405 can be replaced as needed.

[0042] The inner wall of the shell 1 is installed with a No. 2 heat dissipation fin 410, and the inner wall of the shell 1 is fixed with a No. 3 heat dissipation fin 411 on both sides. The No. 2 heat dissipation fin 410 and the No. 3 heat dissipation fin 411 are both detachable. The top of the shell 1 is installed with a cover plate 101, and the cover plate 101 is installed on the top of the shell 1 by screws.

[0043] By adopting the above technical solution, the heat will be absorbed by the second heat sink fin 410 and the third heat sink fin 411, and then transmitted to the outside of the shell 1 through the shell 1, and a large amount of heat will be absorbed and dissipated through the first heat sink fin 405, thereby improving the heat dissipation effect.

[0044] Working principle: When the device needs to be installed, first determine the installation point, then use the rotating tool to rotate the second rotating member 314, the rotation of the second rotating member 314 drives the threaded rod 311 to rotate, and the rotation of the threaded rod 311 drives the first wedge block 312 to move in the adjustment groove 310, so that the first wedge block 312 moves toward the direction of the second rotating member 314. As the first wedge block 312 moves, the second wedge blocks 313 on both sides are no longer pushed by the second wedge block 313. At this time, the compression spring 3 17 rebounds, the compression spring 317 rebounds and pushes the fixed plate 316 and the insertion rod 302 to move, thereby causing the insertion rod 302 to be disengaged from the slot 303, and then the position of the movable frame 301 can be adjusted, and then the position of the mounting hole 305 can be adjusted, and then the position of the two movable frames 301 can be adjusted to facilitate the installation and connection of the device, and then the hexagonal nuts 216 on both sides of the mounting frame 210 are loosened, and then the sliding block 212 is pushed so that the sliding block 212 slides in the sliding groove 211 The height of the fixing frame 202 can be adjusted by the movement. After the adjustment is completed, the sliding block 212 can be tightened by the hexagonal nut 216. By precisely adjusting the angle of the isolator, the alignment of the signal path can be improved, the signal reflection and loss can be reduced, and the isolation performance can be improved. Then the housing 1 can be slid outside the four adjustment rods 201, so that the height of the housing 1 and the isolation assembly 110 can be adjusted. After adjusting to the appropriate height, the No. 1 rotating member 207 is rotated according to the outside, so that the No. 1 rotating member 207 rotates and drives the No. 1 bolt 204 to rotate. As the No. 1 bolt 204 rotates, it will move in the housing 1, thereby moving the positioning block 205 and the soft pad 206. The positioning block 205 and the soft pad 206 will fit with the inner wall of the groove 203, and then the adjusting rod 201 can be tightened, so that the position of the housing 1 can be positioned. The height adjustment can ensure the best connection between the equipment and other components, adapt to different installation environments, simplify the maintenance and debugging process, and improve the overall performance and reliability of the system.

[0045] During the heat dissipation process, the heat generated by the operation of the isolation component 110 will first be absorbed by the No. 2 heat dissipation fins 410 and the No. 3 heat dissipation fins 411, and then transmitted to the outside of the shell 1 through the shell 1, and the heat will be absorbed and dissipated by the No. 1 heat dissipation fins 405, thereby improving the heat dissipation effect and facilitating the installation and disassembly of the heat dissipation mechanism 4.

[0046] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
