[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0027] Reference Figure 1-6 The utility model provides an embodiment: a waterproof chip inductor, including a supporting shell 1, a limiting slot 15 is provided in the middle of the supporting shell 1, a traction rod 4 is slidably connected inside the limiting slot 15, the bottom end of the traction rod 4 is fixedly connected to a main roller 11, the top of the traction rod 4 is fixedly connected to a pulling piece 3, a winding coil 12 is wound around the inner side of the main roller 11, a plurality of air flow slots 17 are evenly provided around the inner side of the main roller 11, both sides of the bottom end of the main roller 11 are fixedly connected to terminal posts 7, a telescopic limiting component is installed on the top of the supporting shell 1, and the bottom of the supporting shell 1 The end is fitted with a bottom gasket 5, the bottom end of the bottom gasket 5 is fixedly connected to a fitting film 6, the bottom gasket 5 is connected to the inner side of the support shell 1 through a sealing mounting assembly, the telescopic limiting assembly includes a rotating notch 8 located at the top of the support shell 1, the interior of the rotating notch 8 is rotatably connected to a positioning fixing ring 2, a threaded notch 10 is provided on the outside of the traction rod 4, the top of the main roller 11 is connected to the inner top of the support shell 1 through a push spring 9, the inner side of the positioning fixing ring 2 is threadedly connected to the threaded notch 10 on the outside of the traction rod 4, and the outside of the terminal 7 passes through the fitting film 6 and both sides of the fitting film 6 respectively;

[0028] When installing the inductor, the protective film at the bottom of the display screen 6 is peeled off, and the cylinder 4 is pulled upward through the supporting arc plate 3. As the cylinder 4 slides inside the exhaust box 15, the soft rubber pad 11 is pulled upward. When the colloid nozzle 10 outside the cylinder 4 is pulled out, the colloid nozzle 10 contacts the inner thread of the mounting frame 2, and the mounting frame 2 is rotated so that the inner thread of the mounting frame 2 is matched with the colloid nozzle 10, thereby fixing the cylinder 4. At this time, the first motor 7 is retracted into the inside of the supporting table 1, and the display screen 6 is attached to the surface of the object to be installed. The mounting frame 2 is rotated in the opposite direction. When the inner thread of the mounting frame 2 is disengaged from the colloid nozzle 10, the connecting pipe 9 generates a downward thrust on the soft rubber pad 11, thereby popping out the first motor 7 for interlaced connection, avoiding direct contact with the tentacles due to external forces, protecting the stability of the inductor joint, and improving safety.

[0029] Reference Figure 4 and Figure 5 The sealing installation assembly includes a connecting sleeve 13 located at the top of the bottom gasket 5, a sealing rubber ring 16 is fixedly connected to the bottom end of the supporting shell 1, and a sealing notch 14 is opened on the outside of the connecting sleeve 13 at the top of the bottom gasket 5.

The outer dimensions of the main roller 11 are adapted to the inner dimensions of the connecting sleeve 13.

[0030] When the inductor is damaged during operation, the colloid placement frame 5 and the support plate 1 rotate relative to each other, and the inner thread of the support plate 1 contacts the outer thread of the second motor 13, thereby disengaging the support plate 1 and removing the support plate 1, so that the internal inductor can be inspected, repaired, and reinstalled. The air valve 16 fits inside the positioning plate 14. As the support plate 1 and the colloid placement frame 5 are squeezed, the air valve 16 completely fills the inside of the positioning plate 14, thereby sealing the inductor, providing convenient maintenance for the damaged inductor, and the inductor is sealed, isolating external moisture, providing waterproof ability, and less internal moisture.

[0031] Working principle: When installing the inductor, peel off the protective film at the bottom of the display screen 6, pull the cylinder 4 upwards through the supporting arc plate 3, and pull the soft rubber pad 11 upwards as the cylinder 4 slides inside the exhaust box 15. When the colloid nozzle 10 outside the cylinder 4 is pulled out, the mounting frame 2 is rotated to fix the cylinder 4. At this time, the first motor 7 is retracted into the inside of the supporting plate 1, and the display screen 6 is attached to the surface of the object to be installed. The mounting frame 2 is rotated in the opposite direction. When the inner thread of the mounting frame 2 is disengaged from the colloid nozzle 10, the connection The connecting pipe 9 generates a downward thrust on the soft rubber pad 11, thereby popping out the first motor 7 for interlaced connection. When the inductor is damaged during operation, the colloid placement frame 5 and the support table 1 rotate relative to each other, thereby separating the support table 1 and removing the support table 1 to inspect, repair and reinstall the internal inductor. The air valve 16 fits inside the positioning plate 14. As the support table 1 and the colloid placement frame 5 are squeezed, the air valve 16 completely fills the inside of the positioning plate 14, thereby sealing the inductor.
