[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a high-sealing inductor coil, including a sealing member 1, a sealing cover 2 connected to the top of the sealing member 1, an inductor coil 3 encapsulated inside the sealing member 1 through the sealing cover 2, an adapter 4 embedded on the front of the sealing member 1, a coil pin 5 located inside the adapter 4 connected to both ends of the coil on the inductor coil 3, and the other end of the coil pin 5 extending to the outside of the sealing member 1 through the adapter 4, and an adjustment member 6 located on the top of the adapter 4 is provided inside the sealing member 1.

[0026] The adapter 4 includes a mounting plate 41 that is fixedly mounted on the front of the seal 1. Two sealing airbag rings 42 are fixedly sleeved inside the mounting plate 41. The coil pins 5 pass through the inside of the sealing airbag rings 42. The mounting plate 41 has a connecting hole 43 inside, and the sealing airbag rings 42 are connected to the adjusting member 6 through the connecting hole 43. Due to the setting of the adapter 4, the sealing airbag rings 42 can be expanded with the cooperation of the adjusting member 6. Then, under the restriction of the mounting plate 41, the inner wall of the sealing airbag rings 42 gradually shrinks and can be sealed and fitted with the outer surface of the coil pins 5 with different diameter specifications, thereby achieving the sealing effect.

[0027] The sealing element 1 includes a sealing cylinder 11 connected to the bottom of the sealing cover 2. The top of the sealing cylinder 11 has an encapsulation cavity 12. The inductor coil 3 is fixedly installed inside the encapsulation cavity 12. The top of the sealing cylinder 11 has an integrally formed connecting ring 13.

[0028] The inner diameter of the connecting ring 13 is larger than the inner diameter of the encapsulation cavity 12, and the outer diameter of the connecting ring 13 is smaller than the distance between the adjusting member 6 and the axis of the sealing cylinder 11.

[0029] The sealing cover 2 includes a sealing cover that is threaded onto the outside of the connecting ring 13. A sealing gasket is movably fitted onto the top of the inner cavity of the sealing cover. The sealing gasket moves down with the sealing cover and finally seals against the top of the connecting ring 13. Due to the setting of the sealing cover 2, with the cooperation of the external threads of the connecting ring 13, it is easy for the operator to connect the sealing cover 2 to the top of the sealing element 1. It is also easy to disassemble it so that the inductor coil 3 inside the encapsulation cavity 12 can be removed for replacement and reuse. With the cooperation of the sealing gasket at the top of the inner cavity of the sealing cover 2, it forms a sealed state with the inside of the encapsulation cavity 12 through the connecting ring 13.

[0030] Among them, the sealing airbag ring 42 is a hollow ring structure. The outer surface of the sealing airbag ring 42 is fixedly sleeved inside the mounting plate 41. The inner diameter of the sealing airbag ring 42 is larger than the outer diameter of the coil pin 5.

[0031] The adjusting component 6 includes a sealing cavity 61 located inside the sealing component 1 and on top of the mounting plate 41. The bottom of the sealing cavity 61 is connected to the upper end of the connecting hole 43. The cross-section of the connecting hole 43 is "V" shaped. The top of the connecting hole 43 is connected to the bottom of the sealing cavity 61. The two ends of the bottom of the connecting hole 43 are respectively fixedly connected to the left and right sealing airbag rings 42. Due to the setting of the adjusting component 6, the connection between the sealing cover 2 and the sealing component 1 will not be affected. Moreover, with the cooperation of the connecting hole 43, it is easy to press part of the air inside the sealing cavity 61, i.e. the bottom of the piston 62, into the interior of the left and right sealing airbag rings 42, thereby achieving the effect of controlling the expansion and contraction of the left and right sealing airbag rings 42. This allows the inner wall of the sealing airbag ring 42 to fit tightly against the outer surface of the coil pins 5 of different specifications to achieve sealing.

[0032] The inside of the sealing cavity 61 is sleeved with the piston 62, the top of the piston 62 is connected with the adjusting rod 63, and the adjusting rod 63 is threadedly sleeved in the inside of the sealing element 1; due to the sealing cavity 61, the piston 62 can move along the inside of the sealing cavity 61 under the control of the adjusting rod 63, so that the air at the bottom of the piston 62 can be pressed into the inside of the sealing air bag ring 42 or extracted from the inside of the sealing air bag ring 42, so that the effect of controlling the expansion and contraction of the sealing air bag ring 42 is achieved.

[0033] The height size of the sealing cavity 61 is greater than the height size of the piston 62, the top of the piston 62 is movably sleeved with the rotating shaft 64, the top of the rotating shaft 64 penetrates through the piston 62 and is fixedly connected to the bottom of the adjusting rod 63; due to the rotating shaft 64, the adjusting rod 63 can drive the piston 62 to move synchronously when the adjusting rod 63 moves up and down, but the piston 62 can rotate with the adjusting rod 63 when the adjusting rod 63 rotates, so that the abrasion of the piston 62 in the sealing cavity 61 is reduced.

[0034] The working principle and use process of the utility model are as follows:

[0035] The inductance coil 3 is placed in the packaging cavity 12, and it is ensured that the two coil pins 5 are penetrated through the two sealing air bag rings 42 to the outside of the sealing cylinder 11, the sealing cover 2 is rotated around the back to be connected to the top of the sealing cylinder 11 under the cooperation of the connecting ring 13, and the sealing gasket at the top of the inner cavity of the sealing cover 2 is continuously rotated to be sealingly attached to the top of the connecting ring 13.

[0036] The adjusting rod 63 is rotated to slowly move down in the cooperation of the threads on the inner wall of the sealing element 1, the piston 62 is pushed to slowly move down along the inner wall of the sealing cavity 61 through the rotating shaft 64 due to the downward movement of the adjusting rod 63, the air in the inside of the sealing cavity 61, that is, the bottom of the piston 62, can be pressed into the inside of the two sealing air bag rings 42 through the communication hole 43 and make the two sealing air bag rings 42 expand, and the inner ring of the sealing air bag ring 42 can be made to shrink inwardly under the limitation of the mounting plate 41, so that the inner wall is tightly attached to the outer surface of the coil pin 5, thereby realizing the sealing effect.
