All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] See also Figure 1 - Fig.10 The present invention provides a technical solution: comprising: a microwave ferrite circulator body 1, an outer wall of the microwave ferrite circulator body 1 is movably connected with a mounting shell 2, an inner conductor 3 is arranged inside the microwave ferrite circulator body 1, and the outer walls on the upper and lower sides of the inner conductor 3 are movably contacted with aluminum plates 42 respectively, and the outer walls on the opposite sides of the two aluminum plates 42 are fixedly connected with a polytetrafluoroethylene dielectric block 41.

[0031] The polytetrafluoroethylene dielectric blocks 41 arranged on the upper and lower sides of the inner conductor 3 serve as part of the heat dissipation channel to help dissipate the heat generated by the inner conductor 3 and reduce the temperature of the inner conductor 3. At the same time, the polytetrafluoroethylene dielectric block 41 can slow down the transfer of heat to a certain extent, play a role in heat insulation, and protect surrounding components and structures from high temperature.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, the outer wall of the top of the polytetrafluoroethylene dielectric block 41 above the inner conductor 3 is fixedly connected to the mounting plate 1 4, the outer wall of the bottom of the polytetrafluoroethylene dielectric block 41 below the inner conductor 3 is fixedly connected to the mounting plate 2 43, the outer walls on both sides of the top of the mounting plate 2 43 are rotatably connected to the fixing rod 5, the outer wall of the top of the mounting plate 4 is rectangular and fixedly connected to the nut 53, the lower part of the outer wall of the fixing rod 5 is fixedly connected to the gear 56, the outer wall of the fixing rod 5 is located above the gear 56 and is fixedly connected to a circular plate, the outer wall of the top of the circular plate is fixedly connected to a buffer spring 52, the inner part of the buffer spring 52 is movably sleeved with the outer wall of the fixing rod 5, the outer wall of the top of the buffer spring 52 is fixedly connected to the outer wall of the bottom of the mounting plate 4, and the upper part of the outer wall of the fixing rod 5 is fixedly connected to Threaded groove 54, the outer wall of the threaded groove 54 is rotatably connected with the interior of the mounting plate 4, the outer wall of the threaded groove 54 is threadedly connected with the internal thread of the nut 53, the outer wall of the gear 56 is meshedly connected with the tooth seat 51, the outer wall of one end of the two tooth seats 51 is fixedly connected with a fixing block 55, the outer wall on the opposite side of the two fixing blocks 55 is fixedly connected with the inner wall of the mounting shell 2, the outer walls on both sides of the mounting plate 2 43 are fixedly connected with the limiting plate 57, the mounting plate 2 43 is provided with grooves on both sides at one end close to the mounting shell 2, the inner part of the groove is slidably connected with a driving plate 7, the outer wall at the bottom of one end of the driving plate 7 is fixedly connected with the lower part of the interior of the mounting shell 2, the outer walls on both sides of the mounting plate 2 43 are fixedly connected with the limiting plate 57, and the inner part of one side of the limiting plate 57 is slidably connected with the outer wall of the tooth seat 51.

[0034] By increasing the distance between the mounting plate 1 4 and the mounting plate 2 43, the contact between the aluminum plate 42 and the inner conductor 3 can be achieved, thereby preventing the aluminum plate 42 from moving while in contact with the inner conductor 3, which would cause scratches on the inner conductor 3 and thus affect the operation of the inner conductor 3. When the scratches are severe, the inner conductor 3 needs to be replaced, which causes a waste of resources. Accordingly, by releasing the contact between the aluminum plate 42 and the inner conductor 3, the aluminum plate 42 is prevented from rubbing against the inner conductor 3 during movement, which would cause scratches on the inner conductor 3, thereby increasing the protection of the inner conductor 3 and extending the service life of the inner conductor 3.

[0035] Embodiment 3

[0036] On the basis of the second embodiment, strip holes with connected outer walls on both sides are opened on both sides of the top of the mounting plate 4, and a storage groove 8 is opened on the outer wall of the mounting plate 4 on one side of the strip hole, and an elastic block 81 is fixedly connected inside the storage groove 8, and the outer wall of one end of the elastic block 81 is fixedly connected to a connecting plate 82, and the outer wall of the connecting plate 82 is slidably connected to the inside of the storage groove 8, and a connecting groove 83 is opened on the outer wall of the mounting plate 4 on the other side of the strip hole, and the inside of the connecting groove 83 is movably plugged into the outer wall of the connecting plate 82, and the two sides of the connecting plate 82 are inclined surfaces, and the outer wall of the slide plate 61 is movably contacted with the outer wall of the connecting plate 82, and the outer wall of the slide plate 61 is slidably connected to the inside of the strip hole.

[0037] By having a connecting plate 82 always inserted into the connecting groove 83, the problem of the mounting plate 4 being unable to move out through the slide plate 61 due to the lack of a strip hole between the mounting plate 4 is avoided, and the obstruction on the movement track of the mounting plate 4 is correspondingly reduced, thereby increasing the movement effect of the mounting plate 4. Furthermore, by having a connecting plate 82 always inserted into the connecting groove 83, the mounting plate 4 can drive the polytetrafluoroethylene medium block 41 to always be connected to the fixing rod 5.

[0038] Embodiment 4

[0039] On the basis of Example 3, a cleaning box 6 is provided inside the mounting shell 2, and a slide groove 21 connected to the outer walls on both sides is opened on the top of the mounting shell 2. Slide plates 61 are fixedly connected to the two sides of the outer wall at the top of the cleaning box 6. The outer walls of the two slide plates 61 are slidably connected to the inside of the slide groove 21, and the outer wall of the top of the slide plate 61 is fixedly connected to the upper part of the interior of the microwave ferrite circulator body 1. A water absorption column 62 is fixedly connected to the upper and lower sides of the cleaning box 6, and the outer walls of the upper and lower sides of the water absorption column 62 are fixedly connected to cleaning brushes 63, and the outer wall on the opposite side of the two cleaning brushes 63 is in active contact with the outer wall on the opposite side of the aluminum plate 42.

[0040] When the polytetrafluoroethylene dielectric block 41 is driven by the mounting plate 4 to pass through the cleaning box 6, the outer wall of the aluminum plate 42 can be cleaned by the cleaning brush 63 on the cleaning box 6, thereby avoiding dust on the aluminum plate 42 and affecting the contact between the aluminum plate 42 and the inner conductor 3, and correspondingly increasing the contact between the aluminum plate 42 and the inner conductor 3.

[0041] In actual use, first, when the microwave ferrite circulator body 1 works under high power conditions, the inner conductor 3 needs to withstand a large current and electromagnetic field, which causes the inner conductor 3 to heat up. As the power increases, the heat generation will also increase accordingly, thereby generating high temperature. Then, the polytetrafluoroethylene dielectric blocks 41 are arranged on the upper and lower sides of the inner conductor 3. The polytetrafluoroethylene dielectric blocks 41 serve as part of the heat dissipation channel to assist in dissipating the heat generated by the inner conductor 3 and reduce the temperature of the inner conductor 3. At the same time, the polytetrafluoroethylene dielectric blocks 41 can slow down the transfer of heat to a certain extent, play a role in heat insulation, and protect the surrounding components and structures from being affected by high temperature. The polytetrafluoroethylene dielectric blocks 41 have extremely strong corrosion resistance and can resist the erosion of various strong acids, strong alkalis and organic solvents. In the complex environment of high temperature and electromagnetic field, this chemical stability is particularly important and can ensure the long-term stable operation of the microwave ferrite circulator body 1.

[0042] By setting an aluminum plate 42 at the bottom of the polytetrafluoroethylene dielectric block 41, the aluminum plate 42 is made to movably contact the upper and lower sides of the inner conductor 3. The high thermal conductivity of the aluminum plate 42 can be utilized to effectively transfer the heat generated by the inner conductor 3 to the external environment, further improving the heat dissipation effect of the inner conductor 3.

[0043] When the polytetrafluoroethylene dielectric block 41 needs to be inspected or replaced, the operator can pull the mounting shell 2, and then the movement of the mounting shell 2 can drive the driving plate 7 and the tooth seat 51 to move at the same time, and then the driving plate 7 slides inside the groove on the mounting plate 2 43, so that the mounting plate 2 43 can remain stationary, thereby avoiding the simultaneous movement of the mounting plate 2 43 and the tooth seat 51, so that the mounting plate 1 4 and the mounting plate 2 43 are fixed to the inner conductor 3 more tightly, and then the outer wall of the inner conductor 3 is scratched, thereby affecting the working effect of the inner conductor 3, and correspondingly, the movement time of the mounting plate 2 43 and the mounting plate 1 4 is staggered with the movement time of the tooth seat 51, so that the tooth seat 51 drives the mounting plate 2 43 to move, thereby increasing the distance between the mounting plate 1 4 and the mounting plate 2 43, reducing the fixation between the mounting plate 1 4 and the mounting plate 2 43, and facilitating the removal of the mounting plate 1 4 and the mounting plate 2 43 from the inner conductor 3.

[0044] Through the movement of the tooth seat 51, the gear 56 can drive the fixing rod 5 to rotate on the mounting plate 2 43, and then through the rotation of the fixing rod 5, the thread groove 54 can be rotated inside the nut 53, and then the movement of the thread groove 54 can be used to drive the mounting plate 1 4 to move upward. Then, through the movement of the mounting plate 1 4, the polytetrafluoroethylene medium block 41 can drive the aluminum plate 42 to move upward, thereby increasing the distance between the mounting plate 1 4 and the mounting plate 2 43, so that the contact between the aluminum plate 42 and the inner conductor 3 can be contacted, thereby avoiding the aluminum plate 42 from moving when in contact with the inner conductor 3, which will cause scratches on the inner conductor 3, thereby affecting the work of the inner conductor 3. When the scratches are serious, the inner conductor 3 needs to be replaced, resulting in a waste of resources. Accordingly, by releasing the contact between the aluminum plate 42 and the inner conductor 3, it is prevented that the aluminum plate 42 rubs against the inner conductor 3 when moving, causing scratches on the inner conductor 3, thereby increasing the protection of the inner conductor 3 and extending the service life of the inner conductor 3.

[0045] When the driving plate 7 moves to one end of the groove, the driving plate 7 can pull the mounting plate 2 43 to move, and then the movement of the mounting plate 2 43 can drive the mounting plate 1 4 to be removed from the interior of the microwave ferrite circulator body 1, so as to facilitate the inspection and maintenance of the polytetrafluoroethylene dielectric block 41, and avoid the occurrence of cracks, breakage, deformation or aging signs in the polytetrafluoroethylene dielectric block 41, which affects the use of the polytetrafluoroethylene dielectric block 41. Accordingly, by inspecting the polytetrafluoroethylene dielectric block 41, problems with the polytetrafluoroethylene dielectric block 41 can be discovered in time so that it can be replaced in time to maintain the working effect of the polytetrafluoroethylene dielectric block 41.

[0046] When the mounting plate 2 43 drives the mounting plate 1 4 to move to the position of the slide plate 61 and continues to move, the setting of the slide plate 61 can squeeze the connecting plate 82. When the connecting plate 82 is subjected to the squeezing force, the connecting plate 82 will squeeze the elastic block 81, so that the connecting plate 82 enters the interior of the storage groove 8, so that the mounting plate 1 4 can be moved out of the interior of the microwave ferrite circulator body 1 through the slide plate 61. Then, since there are two connecting plates 82, when the first connecting plate 82 passes through the slide plate 61, the connecting plate 82 can be pushed back into the interior of the connecting groove 83 under the action of the elastic block 81, so that one of the two connecting plates 82 is always in the interior of the connecting groove 83, avoiding that there is no strip hole between the mounting plates 1 4 and they cannot be moved out through the slide plate 61, correspondingly reducing the obstruction on the movement track of the mounting plate 1 4, increasing the movement effect of the mounting plate 1 4, and since there is always one connecting plate 82 inserted into the interior of the connecting groove 83, the mounting plate 1 4 can drive the polytetrafluoroethylene medium block 41 to be always connected to the fixing rod 5.

[0047] After the inspection of the polytetrafluoroethylene dielectric block 41 is completed, it can be reinserted into the interior of the microwave ferrite circulator body 1 and fixed on the outer wall of the inner conductor 3. When the mounting plate 4 drives the polytetrafluoroethylene dielectric block 41 through the cleaning box 6, the outer wall of the aluminum plate 42 can be cleaned by the cleaning brush 63 on the cleaning box 6, thereby avoiding dust on the aluminum plate 42 and affecting the contact between the aluminum plate 42 and the inner conductor 3, thereby increasing the contact between the aluminum plate 42 and the inner conductor 3 accordingly.

[0048] By setting the water absorption column 62, the clean water inside the cleaning box 6 can be transferred to the cleaning brush 63 through the water absorption column 62, thereby increasing the wetness of the cleaning brush 63 and improving the working effect of the cleaning brush 63. At the same time, the wet cleaning brush 63 can reduce the generation of static electricity and prevent dust and dirt from being re-adsorbed onto the surface of the aluminum plate 42 due to static electricity during the cleaning process.

[0049] It should be noted that: through the square plug provided on the top of the cleaning box 6, the square plug can be removed and clean water can be added to the inside of the cleaning box 6.

[0050] When the mounting plate 2 43 stops moving, the mounting shell 2 can push the tooth seat 51 and the driving plate 7 to move, and the gear 56 can drive the thread groove 54 to move, so that the mounting plate 1 4 drives the polytetrafluoroethylene medium block 41 to move downward, so that the aluminum plate 42 and the inner conductor 3 are closely fitted, avoiding the occurrence of a gap between the aluminum plate 42 and the inner conductor 3, affecting the transmission of heat, and correspondingly increasing the working effect of the aluminum plate 42. By setting the buffer spring 52, when the mounting plate 1 4 moves downward, it can play a buffering and supporting role, preventing the mounting plate 1 4 from driving the polytetrafluoroethylene medium block 41 to squeeze the inner conductor 3 too tightly, causing damage to the inner conductor 3. By setting the limiting plate 57, the movement of the tooth seat 51 can be limited, thereby increasing the stability of the movement of the tooth seat 51.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
