[0002] An induction type self - reset DC electromagnet is an electromagnet device that combines the principle of electromagnetic induction and a mechanical reset mechanism. It generally consists of two major parts: an electromagnet assembly and an induction assembly. The electromagnet assembly is composed of an electromagnet housing, an electromagnetic coil, an iron core, a connecting rod, etc. The iron core is slidably arranged in the electromagnet housing and realizes the self - reset function through a reset spring. The induction assembly includes elements such as a trigger piece and a micro - switch, which are used to detect the position of the iron core and control the on - off of the electromagnet.

[0003] In industrial production, transportation, or specific experimental environments, electromagnet devices often need to withstand vibrations from various factors such as machine operation, vehicle driving, or the external environment. The long - term vibration effect will cause the clearance between the bolt and the screw hole to gradually increase, thereby reducing the pre - tightening force of the bolt and ultimately leading to loosening, which affects the stability and reliability of the electromagnet. Summary of the Utility Model

[0025] In order to more clearly understand the above - mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0027] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: an induction type self - reset DC electromagnet, including an outer shell 1, a base 2 is provided at the bottom of the outer shell 1, bolts 3 are threadedly connected between the outer shell 1 and the base 2, an electromagnet 4 is provided inside the outer shell 1, a push rod 5 is provided at the left end of the electromagnet 4, a limiting component 6 is provided on the base 2, and a cleaning component 7 is provided at the bottom of the outer shell 1;

[0028] The limiting component 6 is slidably connected to the bolt 3 and rotationally limits the bolt 3, and the cleaning component 7 cleans the dust on the surface of the electromagnet 4 by moving left and right.

[0029] The limiting component 6 includes a fixed frame 61 arranged on the front and rear end surfaces of the base 2. Guide rods 62 are arranged on the inner walls of the fixed frame 61. Springs 63 are wound around the guide rods 62. The other end surfaces of the springs 63 are fixedly connected to sliders 64. The sliders 64 slide on the guide rods 62. Pulling rods 65 are arranged on the side surfaces of the sliders 64 facing away from the housing 1. Limiting blocks 66 are arranged on the side surfaces of the sliders 64 facing the housing 1. Limiting grooves 67 are opened on the outer walls of the bolts 3.

[0030] When the user fixes the housing 1 on the base 2, first pull the pulling rod 65 in the direction away from the housing 1, so that the pulling rod 65 drives the slider 64 to slide in the fixed frame 61 on the guide rod 62, and the slider 64 squeezes the spring 63. At the same time, the slider 64 drives the limiting block 66 to move. Then, thread the bolt 3 through the housing 1 and rotate it into the base 2 to connect the housing 1 and the base 2. Then release the pulling rod 65, and use the restoring force of the spring 63 to push the slider 64 to slide back on the guide rod 62, and the slider 64 drives the limiting block 66 to slide into the limiting groove 67 synchronously, so as to achieve the purpose of limiting the rotation of the bolt 3.

[0031] It should be noted that the limiting block 66 is designed in a rectangular shape, and the limiting groove 67 is opened as a counterbore matching the limiting block 66. The limiting groove 67 and the limiting block 66 are well adapted. Through this design, the four sides of the limiting block 66 are fully attached to the four sides of the inner wall of the limiting groove 67, so as to prevent the limiting block 66 from shaking in the limiting groove 67, which may cause the bolt 3 to loosen and affect the connection stability between the housing 1 and the base 2. One end of the spring 63 is welded to the inner wall of the fixed frame 61, and the other end of the spring 63 is welded to the surface of the slider 64. Through this design, the two ends of the spring 63 can be fixed, preventing the spring 63 from vibrating back and forth on the guide rod 62 and hitting the slider 64 and the fixed frame 61 when the housing 1 vibrates, which may cause noise pollution to the environment. The pulling rod 65 is designed in a round handle shape, and the surface of the pulling rod 65 is treated by grinding. Through this design, it is convenient for the staff to pull the pulling rod 65, and at the same time, the friction between the staff's hand and the pulling rod 65 is increased to prevent the situation of hand slipping. The slider 64 slides linearly in the fixed frame 61, and a through hole matching the guide rod 62 is opened in the slider 64. The middle part of the slider 64 slides on the guide rod 62. Through this design, the fixed frame 61 can achieve the purpose of guiding the sliding of the slider 64 and prevent the slider 64 from shaking during the sliding process on the guide rod 62.

[0032] The cleaning component 7 includes a movable bin 71 arranged on the top surface of the housing 1. A bearing 72 is arranged at the left end of the movable bin 71. A lead screw 73 is fixedly connected to the right end of the bearing 72. A transmission block 74 is threadedly connected to the lead screw 73. Cleaning brushes 75 are arranged on the front and rear end surfaces of the transmission block 74. A hand wheel 76 is arranged at the right end of the lead screw 73.

[0033] When it is necessary to clean the dust on the surface of the electromagnet 4, first rotate the handwheel 76, so that the handwheel 76 drives the lead screw 73 to rotate on the bearing 72, and the rotating lead screw 73 acts on the transmission block 74, and drives the transmission block 74 to move back and forth on the lead screw 73. While the transmission block 74 is moving, it synchronously drives two groups of cleaning brushes 75 to clean the dust on the surface of the electromagnet 4;

[0034] It should be noted that the handwheel 76 can also be fixed on the lead screw 73 through bolts. The surface of the handwheel 76 is provided with anti-slip lines. Through this design, when the handwheel 76 is damaged, the handwheel 76 can be disassembled through bolts, so as to facilitate the staff to replace the handwheel 76. At the same time, when using the handwheel 76, the anti-slip lines can be used to increase the friction between the staff and the handwheel 76, preventing the situation of hand slipping when rotating the handwheel 76. Soft hairs are provided on the surface of the cleaning brush 75 facing the electromagnet 4, and the soft hairs are tightly attached to the outer wall of the electromagnet 4. Through this design, the cleaning brush 75 can be fully attached to the surface of the electromagnet 4, so as to improve the cleaning efficiency of the cleaning brush 75, and at the same time reduce the frictional damage of the cleaning brush 75 to the surface of the electromagnet 4. The transmission block 74 is designed in a cross shape, and through holes adapted to the transmission block 74 are opened in the movable bin 71. The transmission block 74 moves linearly in the movable bin 71. Through this design, the movable bin 71 can achieve the purpose of limiting the rotation of the transmission block 74, so that under the action of the thread of the lead screw 73, the transmission block 74 makes a linear reciprocating motion in the movable bin 71.

[0035] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
