Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a bidirectional combined magnetic ring, comprising a shell 1, a forward magnetic ring 8 is arranged on the inner side of the shell 1, a reverse magnetic ring 2 is arranged on the inner side of the shell 1 and below the forward magnetic ring 8, mesh boxes 7 are arranged on the outer sides of the forward magnetic ring 8 and the reverse magnetic ring 2 and on the inner side of the shell 1, a support plate 6 is arranged below the shell 1, a fixed plate 5 is arranged below the support plate 6, the shell 1 and the two mesh boxes 7 are connected by a connecting drying device 3, and the support plate 6 and the fixed plate 5 are connected by a shift buffer device 4.

[0023] Specifically, the connecting drying device 3 includes a vertical plate 31, a compression spring 33, a connecting frame 36 and a spring pin 37. Two connecting frames 36 are installed on the two mesh boxes 7 and located outside the shell 1. The top of the connecting frame 36 is installed with a spring pin 37. The vertical plate 31 is installed below the shell 1 and located above the support plate 6. Two compression springs 33 are installed between the vertical plate 31 and the bottom of the two connecting frames 36.

[0024] By adopting the above technical solution, the magnetic rings can be disassembled by simple operations to disassemble the forward magnetic ring 8 and the reverse magnetic ring 2 when needed, thereby reducing the difficulty of the disassembly work and alleviating the labor burden of the staff.

[0025] Specifically, the connection drying device 3 further includes a silica gel desiccant 34 and a threaded barrel 35 . The threaded barrel 35 is threadedly mounted on the connection frame 36 and located on one side of the mesh box 7 . The inside of the threaded barrel 35 is filled with silica gel desiccant 34 .

[0026] By adopting the above technical solution, the magnetic rings can keep the areas around the forward magnetic ring 8 and the reverse magnetic ring 2 dry through the silica gel desiccant 34 when needed, thereby reducing the possibility of the work being affected by the surrounding moisture.

[0027] Specifically, the connecting drying device 3 further includes a threaded rod 32 , and the threaded rod 32 is installed above the support plate 6 and at a position located inside the vertical plate 31 .

[0028] By adopting the above technical solution, the staff can adjust the height of the positive magnetic ring 8 and the reverse magnetic ring 2 through the cooperation of the vertical plate 31 and the threaded rod 32 when necessary, so as to better meet the working needs in different situations.

[0029] When the present embodiment is used, when it is necessary to use the bidirectional combination magnetic ring, the fixing plate 5 is fixed in the working position, and then the vertical plate 31 in the connection drying device 3 is rotated, and the vertical plate 31 is threadedly connected to the threaded rod 32, so that the vertical plate 31 is rotated and raised, thereby adjusting the height of the structures such as the reverse magnetic ring 2 and the forward magnetic ring 8, and then the reverse magnetic ring 2 and the forward magnetic ring 8 can be used. During use, the silica gel desiccant 34 in the two threaded cylinders 35 ensures the drying of the two mesh boxes 7 and the reverse magnetic ring 2 and the forward magnetic ring 8. When it is necessary to disassemble the reverse magnetic ring 2 and the forward magnetic ring 8, the staff only needs to pull the two spring pins 37 to separate them from the shell 1, and then the two connecting frames 36 move under the action of the two compression springs 33, thereby driving the two mesh boxes 7 and the reverse magnetic ring 2 and the forward magnetic ring 8 to leave the shell 1, and then the staff can remove the reverse magnetic ring 2 and the forward magnetic ring 8.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the shift buffer device 4 includes a connecting box 41, a knob 42, a screw rod 43, a movable plate 44 and an outer ring plate 45, a connecting box 41 is arranged between the support plate 6 and the fixed plate 5, a knob 42 is arranged on one side of the connecting box 41, a screw rod 43 is installed on the side of the knob 42 close to the connecting box 41, a movable plate 44 is installed below the support plate 6 and at a position located on the inner side of the connecting box 41 and the outer side of the screw rod 43, and an outer ring plate 45 is installed on the outer side of the connecting box 41 and at a position above the knob 42.

[0032] By adopting the above technical solution, the staff can adjust the positions of the forward magnetic ring 8 and the reverse magnetic ring 2 through the cooperation of the screw rod 43 and the movable plate 44 after the magnetic ring is fixed, so as to better meet the working needs in different situations.

[0033] Specifically, the displacement buffer device 4 also includes an elastic rubber tube 46 and a small damper 47. A plurality of elastic rubber tubes 46 are installed between the outer ring plate 45 and the fixed plate 5. A plurality of small dampers 47 are installed between the outer ring plate 45 and the fixed plate 5 and at positions located on the inner side of each elastic rubber tube 46.

[0034] By adopting the above technical solution, the magnetic ring can buffer external vibration to a certain extent through the cooperation of the elastic rubber tube 46 and the small damper 47, thereby reducing the possibility of adverse effects on structures such as the forward magnetic ring 8 and the reverse magnetic ring 2.

[0035] When this embodiment is used, when it is necessary to adjust the positions of structures such as the reverse magnetic ring 2 and the forward magnetic ring 8, the staff can rotate the knob 42 in the shift buffer device 4, thereby driving the screw rod 43 to rotate. The screw rod 43 is threadedly connected to the movable plate 44, and the outer side of the movable plate 44 and the inner side of the connecting box 41 are tightly attached to each other, so the screw rod 43 drives the movable plate 44 and the support plate 6 thereon and other structures to move, thereby adjusting the positions of structures such as the reverse magnetic ring 2 and the forward magnetic ring 8. The multiple elastic rubber tubes 46 and multiple small dampers 47 between the outer ring plate 45 and the fixed plate 5 can buffer external vibrations.

[0036] The structure and principle of the reverse magnetic ring 2 and the forward magnetic ring 8 in the utility model have been disclosed in a bidirectional combined magnetic ring disclosed in Chinese patent application No. 202321575166.7. The working principle is that after the forward magnetic ring and the reverse magnetic ring are set, the external magnetic field acts on the two magnetic rings at the same time. Since the nanocrystalline soft magnetic tape material wound on the outer arc surface of the forward magnetic ring or the reverse magnetic ring is in opposite directions, the interference signals generated are also opposite. When the two iron cores are the same, the interference signals are offset by each other; since the forward magnetic ring and the reverse magnetic ring are stacked up and down, and are limited by protective grooves and positioning rods, the use status of the forward magnetic ring and the reverse magnetic ring is guaranteed, and the installation of two sets of limit seats is used to ensure that the staff can quickly distinguish The forward magnetic ring and the reverse magnetic ring are pressed against the forward magnetic ring and the reverse magnetic ring by the lifting and lowering of the pressure plate, so as to further limit the position. At the same time, the forward magnetic ring and the reverse magnetic ring can be quickly replaced or adjusted due to the installation of the limit seat. The magnetic ring is mainly used in the three-phase through-type isolation current transformer. When a single magnetic ring is used, the error difference of the current transformer during forward and reverse connection is: the ratio difference is 0.05%, and the angle difference is 1.2 points. After the bidirectional magnetic ring is used, the error difference of the current transformer during forward and reverse connection is: the ratio difference is 0.01%, and the angle difference is 0.3 points. The three-phase through-type isolation current transformer using the bidirectional magnetic ring is combined with other improvement measures, so that the accuracy of the transformer is improved from the original 0.01% to 0.005%.

[0037] The structure and principle of the small and medium-sized damper 47 of the utility model have been disclosed in a micro-box device for computer network security disclosed in Chinese Patent Application No. 202020567163.9. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0038] The working principle and use process of the utility model are as follows: when it is necessary to use the two-way combined magnetic ring, fix the fixing plate 5 in the working position, and then rotate the vertical plate 31 connected to the drying device 3. The vertical plate 31 is threadedly connected to the threaded rod 32, so the vertical plate 31 rotates and rises, thereby adjusting the height of the reverse magnetic ring 2 and the forward magnetic ring 8 and other structures, and then the reverse magnetic ring 2 and the forward magnetic ring 8 can be used. During use, the silica gel desiccant 34 in the two threaded cylinders 35 ensures the drying of the two mesh boxes 7 and the reverse magnetic ring 2 and the forward magnetic ring 8. When it is necessary to disassemble the reverse magnetic ring 2 and the forward magnetic ring 8, the staff only needs to pull the two spring pins 37 to separate them from the shell 1, and then the two connecting The connecting frame 36 moves, thereby driving the two mesh boxes 7 and the reverse magnetic ring 2 and the forward magnetic ring 8 to leave the shell 1, and then the staff can remove the reverse magnetic ring 2 and the forward magnetic ring 8; when it is necessary to adjust the position of the reverse magnetic ring 2 and the forward magnetic ring 8 and other structures, the staff can turn the knob 42 in the shift buffer device 4, thereby driving the screw rod 43 to rotate, the screw rod 43 is threadedly connected to the moving plate 44, and the outer side of the moving plate 44 and the inner side of the connecting box 41 are tightly attached to each other, so the screw rod 43 drives the moving plate 44 and the support plate 6 thereon and other structures to move, thereby adjusting the position of the reverse magnetic ring 2 and the forward magnetic ring 8 and other structures, and the multiple elastic rubber tubes 46 and multiple small dampers 47 between the outer ring plate 45 and the fixed plate 5 can buffer external vibrations.

[0039] 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.
