The left-handed and right-handed threaded rod is installed in the middle of the protective cover. The ends of the two hooks that are close to each other are respectively installed on rod bodies with different rotation directions at both ends of the left-handed and right-handed threaded rods. The ends of the two hooks that are away from each other extend to the outside of the protective cover.

[0013] The utility model provides a magnetic core with a protective structure, which has the following beneficial effects:

[0014] 1: In the utility model, the vibration force transmitted to the magnetic core body is reduced by the airbag, thereby avoiding the phenomenon that the magnetic core body breaks free from the constraint and collides with the box body and finally causes it to be damaged. At the same time, when the vibration force is too large and the magnetic core body moves to one side under the drive of the force, the part of the airbag on this side that is squeezed is compressed, and the other parts that are not squeezed by the magnetic core body are further expanded by the increased air pressure. Finally, there is still an elastic body wall of the airbag as a partition between the magnetic core body and the protective box body, so that the magnetic core body cannot directly collide with the box body of the protective box, that is, the phenomenon that the magnetic core body is directly damaged when colliding with the protective box is effectively reduced. When the vibration force transmitted from the outside is slightly weak, that is, the force transmitted to the magnetic core body is less than the internal pressure of the airbag, the magnetic core body is gradually pushed to the middle of the inside of the protective box by the pressure inside the airbag, that is, the axis of the magnetic core body gradually coincides with the circle at one end of the arc of each airbag, thereby achieving the effect of automatically re-constraining the magnetic core body after breaking free from the constraint.

[0015] 2: The setting of the locking assembly in the utility model ensures that during the process of the airbag restraining the magnetic core body, the air pressure provided by the gas inside the airbag cannot push the protective cover outward, that is, the internal pressure of the airbag can be maintained in a relatively high range for a long time; the setting of the buffer block facilitates further protection of the magnetic core body; the setting of the observation window facilitates personnel to observe the status between the magnetic core body and the airbag inside the protection box; the setting of the quick-release assembly facilitates personnel to open the end of the protection box, thereby facilitating the removal or placement of the magnetic core body; the setting of the mounting protrusion facilitates the installation and fixation of the airbag; the staggered airbags can better restrain and fix the magnetic core body.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] Reference Figure 1-9 A magnetic core with a protective structure comprises a magnetic core body 1 and a protection box 2, wherein two groups of U-shaped air bags 3 are arranged inside the protection box 2, the openings of the two groups of air bags 3 are far away from each other, and the centers of the arc-shaped ends of the two groups of air bags 3 that are close to each other coincide and together form an annular constraint space, the magnetic core body 1 is inserted in the constraint space, and the two ends of the protection box 2 are respectively provided with a protective cover 4 and a sealing cover 10 through a locking assembly and a quick-release assembly, a connecting cavity 5 is arranged inside the body wall of the protection box 2, and the bottom of the connecting cavity 5 is connected to a plurality of air bags 3 through a connecting pipe, a piston cavity 6 is connected to one side of the upper part of the connecting cavity 5, and a piston 7 is arranged inside the piston cavity 6, one end of the piston 7 extends to the outside of the protection box 2 and is fixedly connected to the protective cover 4, and the piston 7 and the piston cavity 6 have good air tightness through a rubber sleeve or the like.

[0029] Example 2

[0030] Reference Figure 1-9 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0031] The locking assembly includes a left-handed and right-handed threaded rod 8 and two hooks 9. The left-handed and right-handed threaded rod 8 is installed in the middle of the protective cover 4. The ends of the two hooks 9 that are close to each other are respectively installed on rod bodies with different rotation directions at both ends of the left-handed and right-handed threaded rod 8. The ends of the two hooks 9 that are away from each other extend to the outside of the protective cover 4. The outer wall of the protective box 2 is provided with a matching card groove corresponding to the end of the hook 9 located outside the protective cover 4. The setting of the locking assembly ensures that during the process of the airbag 3 restraining the magnetic core body 1, the air pressure provided by the gas inside the airbag 3 cannot push the protective cover 4 outward, that is, the internal pressure of the airbag 3 can be maintained in a higher range for a long time.

[0032] A buffer block 11 is installed in the middle of the inner side of the protective cover 4 and the sealing cover 10. One end of the buffer block 11 away from the protective cover 4 and the sealing cover 10 abuts against the end of the magnetic core body 1. The setting of the buffer block 11 is convenient for further providing protection for the magnetic core body 1; four observation windows 12 are installed on the plate body of the sealing cover 10, and the observation windows 12 are distributed in a cross shape on the outside of adjacent buffer blocks 11. The setting of the observation windows 12 is convenient for personnel to observe the state between the magnetic core body 1 and the airbag 3 inside the protective box 2; the quick-release assembly includes four pull ropes 15, a sliding frame 13, a hook 14 and a limiting column. One end of the four pull ropes 15 is connected to the sealing cover 10, and the other end of the pull rope 15 is connected to the sliding frame 13. The protective box 2 is connected with the frame 13, the sliding frame 13 is sleeved on the outside of the protective box 2, the hook 14 is rotatably installed on the side of the sliding frame 13 away from the pull rope 15, the limit column is fixed on the outer wall of the protective box 2 and cooperates with the hook 14, and the setting of the quick-release assembly is convenient for personnel to open the end of the protective box 2, so as to facilitate the removal of the magnetic core body 1; a plurality of installation protrusions are provided inside the protective box 2, and the airbags 3 are arranged in each installation protrusion. The setting of the installation protrusions is convenient for the installation and fixation of the airbags 3; the number of capsules used to constrain the magnetic core body 1 in the two groups of airbags 3 differs by one, and the capsules in the two groups of airbags 3 are staggered. The staggered airbags 3 can better constrain and fix the magnetic core body 1.

[0033] Principle and advantages of use: During the use of the utility model, when the magnetic core body 1 is transported or stored, the personnel first pulls the protective cover 4 so that the protective cover 4 drives the piston 7 to move toward the end away from the protection box 2, and as the piston 7 moves, the space inside the piston cavity 6 is increased, that is, suction is generated inside the piston cavity 6, so that the gas inside each airbag 3 is sucked through the connecting cavity 5, that is, at this time the airbag 3 gradually shrinks, thereby increasing the inner space of the arc-shaped end of the airbag 3, and then another person can directly insert the magnetic core body 1 on the inner side of the arc-shaped end of each airbag 3, and then the personnel pushes the protective cover 4 to move toward the protection box 2. At this time, the space in the piston cavity 6 that can store air is compressed, that is, the gas inside the piston cavity 6 is squeezed into the connecting cavity 5, and finally squeezed into the airbag 3, that is, the gas inside the airbag 3 increases, the air pressure increases, and the airbag 3 expands accordingly, and the inner side of the expanded airbag 3 can forcefully abut against the outer wall of the magnetic core body 1, that is, a plurality of airbags 3 form a relatively firm restraint effect on the magnetic core body 1.

[0034] In the above process, since the magnetic core body 1 is restrained by the airbag 3, that is, during transportation and storage, the vibration force transmitted to the magnetic core body 1 is reduced by the airbag 3, thereby preventing the magnetic core body 1 from breaking free from the constraint and colliding with the box body and eventually causing damage to it. At the same time, when the vibration force is too large and the magnetic core body 1 moves to one side under the drive of the force, the part of the airbag 3 on this side that is squeezed is compressed, and the remaining parts that are not squeezed by the magnetic core body 1 are further expanded by the increased air pressure. Finally, there is still the elastic body wall of the airbag 3 as a partition between the magnetic core body 1 and the box body of the protection box 2, so that the magnetic core body 1 cannot directly collide with the box body of the protection box 2, that is, the phenomenon of the magnetic core body 1 being directly damaged when colliding with the protection box 2 is effectively reduced.

[0035] Furthermore, in the above process, when the vibration force transmitted from the outside is slightly weak, that is, the force transmitted to the magnetic core body 1 is less than the internal pressure of the airbag 3, the magnetic core body 1 is gradually pushed to the middle of the inside of the protective box 2 by the pressure inside the airbag 3, that is, the axis of the magnetic core body 1 gradually coincides with the circle at one end of the arc of each airbag 3, thereby achieving the effect of automatically re-constraining the magnetic core body 1 after breaking free from the constraint.

[0036] It should be further explained that the setting of the locking assembly ensures that during the process of the airbag 3 restraining the magnetic core body 1, the air pressure provided by the gas inside the airbag 3 cannot push the protective cover 4 outward, that is, the internal pressure of the airbag 3 can be maintained in a relatively high range for a long time; the setting of the buffer block 11 is convenient for further providing protection for the magnetic core body 1; the setting of the observation window 12 is convenient for personnel to observe the status between the magnetic core body 1 and the airbag 3 inside the protective box 2; the setting of the quick-release assembly is convenient for personnel to open the end of the protective box 2, so as to facilitate the removal or placement of the magnetic core body 1; the setting of the installation protrusion is convenient for the installation and fixation of the airbag 3; the staggered airbags 3 can better restrain and fix the magnetic core body 1.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
