[0032] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-5 The present invention provides a technical solution: an inductor coil protection device with high protection performance and easy to install, comprising an inductor coil body 3, a box body 1 carrying the inductor coil and a protective shell 4 movably connected to the box body 1, the box body 1 is provided with a fixing groove 11 matching the protective shell 4, and both sides of the protective shell 4 are provided with plug holes 41 near the bottom, and also comprises a door frame 5 located outside the protective shell 4, an insulating cover 8 and an elastic telescopic rod 6 located inside the protective shell 4, the door frame 5 plays a role in driving the elastic telescopic rod 6 to contract, and the insulating cover 8 is used to increase the protection effect, a positioning hole 111 is provided on one side of the fixing groove 11, one end of the elastic telescopic rod 6 is fixedly sleeved in the positioning hole 111, and the elastic telescopic rod 6 is composed of a guide sleeve 61 located in the positioning hole 111, a guide rod 62 matching the plug hole 41 and a compression spring 6 3, the elastic telescopic rod 6 is horizontally distributed and arranged in the fixed groove 11 and used in conjunction with the socket 41. After the elastic telescopic rod 6 is stretched, it is inserted into the socket 41 to lock the protective shell 4, the door frame 5 and the protective shell 4 are slidably matched up and down, and the bottom and one end of the elastic telescopic rod 6 are slidably matched, and the two sides of the protective shell 4 are provided with slide grooves 42 that are slidably matched with two vertical plates 51 on the door frame 5. The slide grooves 42 are connected with the socket 41 to facilitate the vertical plate 51 to move down and push the guide rod 62. The matching ends of the guide rod 62 and the vertical plate 51 are wedge-shaped, and the vertical force is applied by inclined drive. The elastic telescopic rod 6 shrinks laterally, and the top of the insulating cover 8 is fixedly provided with a driving rod 81 that penetrates the protective shell 4 and is fixedly connected to the door frame 5. When installed, the insulating cover 8 moves down to increase the protection gap and improve the protection level.

[0034] Specifically, Figure 2 As shown, heat dissipation holes 7 are provided on the side walls of the protective shell 4 and the insulating cover 8, and heat dissipation holes 7 are provided both inside and outside to facilitate heat dissipation. The heat dissipation holes 7 at two positions can also be staggered, thereby also playing a dust-proof role.

[0035] Specifically, Figure 2 As shown, it also includes a reset spring 2. The door frame 5 is connected to the top of the protective shell 4 through the reset spring 2. The reset spring 2 can also be mounted on the driving rod 81. When the door frame 5 is pressed, the reset spring 2 is compressed. After releasing the door frame 5, the door frame 5 automatically resets, which makes the operation more convenient.

[0036] Specifically, a rubber pad that seals with the protective shell 4 is bonded to the bottom of the fixing groove 11. When the door frame 5 is manually controlled to be pressed back and forth, the insulating cover 8 is driven to move downward, thereby the accumulated dust inside can be discharged by air pressure, which has the effect of cleaning the dust.

[0037] Working principle: When in use, hold the door frame 5 and insert the protective shell 4 into the fixed groove 11. The bottom of the protective shell 4 contacts the wedge-shaped surface at the end of the guide rod 62. When the guide rod 62 encounters a large resistance to sliding outward, continue to press the door frame 5, the reset spring 2 is compressed, and the inclined surface of the wedge-shaped structure at the end of the vertical plate 51 contacts the inclined surface of the wedge-shaped structure on the guide rod 62, thereby pushing the guide rod 62 to slide laterally outward, and the compression spring 63 is compressed. At this time, the protective shell 4 is inserted into the bottom of the fixed groove 11, and the door frame 5 is released. The vertical plate 51 moves upward under the push of the reset spring 2, and the guide rod 62 extends out and is inserted into the socket 41 under the push of the compression spring 63. At this time, the installation of the protective shell 4 is completed. During this installation process, the insulating cover 8 is located in the protective shell 4 to play a double protection role.
