[0026] The housing 3 is connected to the base plate 2 by connecting the first connecting portion and the second connecting portion.

[0027] Specifically, refer to Figure 5 and Figure 6The first connecting part includes a cylinder 901 fixed to the bottom of the shell 3, a circular groove 902 is arranged on the outside of the cylinder 901, and the other end of the cylinder 901 is connected to a conical head 904 through a vertical shaft 903. The diameter of the vertical shaft 903 is smaller than the diameters of the cylinder 901 and the conical head 904, so that a slot 905 is formed in the peripheral area of ​​the vertical shaft 903.

[0028] The second connection part includes a hollow column 906 disposed on the bottom plate 2, the bottom of the hollow column 906 extends out of the bottom plate 2, a first electromagnet 907 is fixed to the bottom of the hollow column 906, an iron sleeve 908 is slidably connected to the outside of the hollow column 906, the sleeve 908 includes an extrusion layer 909 and a hollow groove 910, a convex ring 911 is fixed to the bottom of the hollow column 906, a first spring 912 is disposed outside the hollow column 906, the first spring 912 is located between the sleeve 908 and the convex ring 911, and a conical groove 913 is disposed at the bottom of the hollow column 906; Limiting grooves 914 are evenly distributed on the outside of the hollow column 906 , and spherical clamping blocks 915 are arranged inside the limiting grooves 914 . The clamping blocks 915 are used to cooperate with the circular grooves 902 .

[0029] The limiting groove 914 is wide at one side close to the extrusion layer 909 and narrow at one side away from the extrusion layer 909 , and the narrowest part of the limiting groove 914 is larger than the diameter of the block 915 , so as to prevent the block 915 from falling out of the limiting groove 914 .

[0030] An iron plug 916 is disposed inside the hollow column 906. The plug 916 is deformable and connected to each other to form a whole. A second electromagnet 917 is disposed at the bottom of the hollow column 906. When the second electromagnet 917 is powered on, the plug 916 moves toward the side close to the second electromagnet 917. When the second electromagnet 917 is powered off, the plug 916 is reset and enters the slot 905. When the first electromagnet 907 and the second electromagnet 917 are powered on at the same time, the first connecting portion can be inserted into the second connecting portion. When the first electromagnet 907 and the second electromagnet 917 are powered off, the first connecting portion is connected to the second connecting portion.

[0031] Optionally, the housing 3 of the electromagnetic lock body 1 is separately provided with a button for controlling the first electromagnet 907 and the second electromagnet 917 , and the button is separate from the indication button and the operation button.

[0032] It should be noted that the first electromagnet 907 and the second electromagnet 917 are energized by the button of the electromagnetic lock body 1. When the first electromagnet 907 is energized, the iron sleeve 908 is attracted by a strong magnetic force, and then the sleeve 908 descends outside the hollow column 906 and compresses the first spring 912. When the sleeve 908 descends, the extrusion layer 909 on the inner side thereof leaves the position of the block 915, and the hollow groove 910 moves to the position of the block 915, and then the extrusion layer 909 presses against the block 915. The pressure disappears, and the block 915 can move between the limit groove 914 and the hollow groove 910. The limit groove 914 is wider on the side close to the extrusion layer 909 and narrower on the side away from the extrusion layer 909. The narrowest part of the limit groove 914 is larger than the diameter of the block 915, so as to prevent the block 915 from falling out of the limit groove 914. After the second electromagnet 917 is energized, the plug 916 is attracted, and then the plug 916 is deformed and close to the inner wall of the hollow column 906, and then the cylindrical 901 at the bottom of the shell 3 is Insert the conical head 904 into the interior of the hollow column 906, and then the conical head 904 moves into the interior of the conical groove 913, and the circular groove 902 is just located at the position of the block 915, and then the first electromagnet 907 and the second electromagnet 917 are powered off, and the adsorption force of the first electromagnet 907 on the sliding sleeve 908 disappears after the power is turned off, and then the first spring 912 is reset to drive the sliding sleeve 908 to rise, and then the squeezing layer 909 rises and re-presses the block 915, forcing the block 915 to enter the interior of the slot 905, and the second electromagnet After the iron 917 is powered off, the plug block 916 recovers its deformation, and then multiple plug blocks 916 enter the interior of the circular groove 902, which is conducive to firmly fixing the cylinder 901 inside the hollow column 906 through the coordinated use of the clamping block 915 and the plug block 916, and then fixing the shell 3 on the top of the bottom plate 2. When the electromagnetic lock body 1 needs to be disassembled and repaired, the first electromagnet 907 and the second electromagnet 917 are energized again, and the plug block 916 leaves the slot 905, and then the bottom plate 2 can be separated from the shell 1.

[0033] like Figure 8 As shown, further, a second spring 12 is fixed on the inner side of the through slot 5, a second arc-shaped clamping plate 13 is fixed on one end of the second spring 12, and a micro switch 14 is arranged on the inner side of the second arc-shaped clamping plate 13. The second spring 12 is arranged so that the second arc-shaped clamping plate 13 can adapt to grounding rods 6 of different diameters. Due to the rebound force of the second spring 12, grounding rods 6 of different sizes and diameters can be fitted with the second arc-shaped clamping plate 13, so that grounding rods 6 of different diameters can be in contact with the micro switch 14, and then the installed grounding rod 6 is clamped and fixed with the micro cylinder 71.

[0034] The electromagnetic lock body 1 is provided with four modules inside, including a shell structure module, a logic locking module, a manual unlocking module, and a power supply module. The modular design makes the modules replaceable and easy to assemble, saving the maintenance time of the electromagnetic lock body 1. The shell structure adopts a double-compartment design, which can realize the isolation of the lock body side and the power supply side, protect the internal components, and reduce the humidity in the cabin. The logic locking, mechanical unlocking, status indicator light and operation buttons are in one compartment, and the aviation plug terminal and the step-down module are in another compartment. A waterproof strip and an inner guide groove are added to the gap between the lock body compartment and the power supply compartment of the electromagnetic lock body 1, and a waterproof gasket is added to the grounding wire hole. This design prevents water drops and condensation from forming between the lock body compartment and the power supply compartment. The logic interlocking module adopts relay type, which has low manufacturing cost, long service life, reliable contact output and fast response. All logic interlocking is realized through relays, and more contacts are introduced through a small number of mechanical switches. The manual unlocking module includes a step-down module, a protection module, and an operation module. The step-down module converts 220V AC into 12V DC to reduce the risk of electric shock to personnel and increase the module replacement speed to less than 60s. The step-down module is plug-in type, and the power supply incoming line connection line, status indicator light, and operation button connection line are connected to the circuit board through a connector, which shortens the replacement time. The plug-in output ripple is less than <100mV, the module load short-circuit response time is short, it has excellent waterproof performance and long service life. The plug-in type is specifically encapsulated, and the overall potting glue treatment meets the requirements of the selection basis. The protection module can protect the wiring inside the lock body and prevent the mechanical device from wearing out the wiring insulation. The protection module is isolated by a metal baffle. A metal isolation baffle is installed above the coil transmission sheet. The indicator light connection line, button connection line, and coil connection line are tied with cable ties to fully isolate the connection line from the transmission sheet. After the metal isolation baffle is installed, the transmission sheet scratch rate is 0 and the service life is long. The operation module is convenient for replacing frequently damaged parts and reducing maintenance costs. The operation module adopts split installation and has a long service life. The power supply module can be hot-swapped in less than 10 seconds, quickly introduced into and out of the device, and reduces the incidence of short-circuit failures during wiring. It uses a screw-locking aviation plug with high reliability and short production time.

[0035] Working principle: through the disassembly structure 9, the first electromagnet 907 and the second electromagnet 917 are energized through the button of the electromagnetic lock body 1. When the first electromagnet 907 is energized, the iron sleeve 908 is attracted by the strong magnetic force, and then the sleeve 908 descends outside the hollow column 906 and compresses the first spring 912. When the sleeve 908 descends, the extrusion layer 909 on the inner side leaves the position of the block 915, and the hollow groove 910 moves to the position of the block 915. Then the pressure of the extrusion layer 909 on the block 915 disappears, and the block 915 can be in the limit groove 914 and The limiting groove 914 is wider on one side close to the extrusion layer 909 and narrower on the other side away from the extrusion layer 909. The narrowest part of the limiting groove 914 is larger than the diameter of the block 915 to prevent the block 915 from falling out of the limiting groove 914. After the second electromagnet 917 is energized, the plug block 916 is adsorbed, and then the plug block 916 is deformed and close to the inner wall of the hollow column 906. Then, the cylinder 901 at the bottom of the shell 3 is inserted into the interior of the hollow column 906. Then, the conical head 904 moves into the interior of the conical groove 913, and the circular groove 902 is just located at the position of the block 915. Then, the first electromagnet 917 is energized. The magnet 907 and the second electromagnet 917 are powered off. After the first electromagnet 907 is powered off, the adsorption force on the sliding sleeve 908 disappears, and then the first spring 912 is reset to drive the sliding sleeve 908 to rise, and then the extrusion layer 909 rises and re-presses the block 915, forcing the block 915 to enter the inside of the slot 905. After the second electromagnet 917 is powered off, the plug block 916 recovers its deformation, and then multiple plug blocks 916 enter the inside of the circular groove 902, which is conducive to firmly fixing the cylinder 901 inside the hollow column 906 through the cooperation of the block 915 and the plug block 916, and then fixing the shell 3 on the bottom plate 2. When the electromagnetic lock body 1 needs to be disassembled and repaired, the first electromagnet 907 and the second electromagnet 917 are energized again, and the plug block 916 is removed from the slot 905, and then the bottom plate 2 can be separated from the shell 1, which is conducive to the disassembly and installation of the electromagnetic lock body 1 by powering off and on the first electromagnet 907 and the second electromagnet 917. The whole process takes a short time, which is conducive to solving the problem that the screws are removed by a screwdriver and then the shell is opened during the existing maintenance, and the screws are fixed after the maintenance is completed. Due to the large number of screws and the need to use a screwdriver, the whole disassembly and assembly process is cumbersome and time-consuming. Through the connection mechanism 7, the grounding rod 6 is installed in the electromagnetic lock body 1, the output end of the micro cylinder 71 extends out and moves with the connecting plate 74, and then the two rods 73 rotate in the opposite direction and move with the two first arc clamping plates 75 in the opposite direction. The first arc clamping plates 75 are conducive to clamping grounding rods of different diameters, so as to adapt to grounding rods of different diameters. In addition, the electromagnetic lock body 1 is provided with a voice prompt function, which can voice prompt the status of the switch node, which is convenient for fault maintenance. The electromagnetic lock body 1 is provided with four modules inside, including a shell structure module, a logic locking module, a manual unlocking module, and a power supply module. The modular design makes the modules replaceable and easy to assemble, saving the maintenance time of the electromagnetic lock body 1. The shell structure adopts a double-compartment design, which can realize the isolation of the lock body side and the power supply side, protect the internal components, and reduce the humidity in the cabin. The logic locking, mechanical unlocking, status indicator light and operation buttons are in one compartment, and the aviation plug terminal and the step-down module are in another compartment. A waterproof strip is added to the gap between the lock body compartment and the power supply compartment of the electromagnetic lock body 1. The diversion groove and the grounding wire hole are equipped with waterproof gaskets. This design makes the lock body compartment and the power supply compartment free of water drops and condensation. The logic interlocking module adopts relay type, which has low manufacturing cost, long service life, reliable contact output and fast response. All logic interlocks are realized through relays, and more contacts are introduced through a small number of mechanical switches. The manual unlocking module includes a step-down module, a protection module and an operation module. The step-down module converts 220V AC into 12V DC to reduce the risk of electric shock to personnel and increase the module replacement speed to less than 60s. The step-down module adopts plug-in type to connect the power supply line The wires, status indicator lights and operation button connection wires are connected to the circuit board through connectors, and the required replacement time is short.

The protection module is isolated by a metal baffle, and a metal isolation baffle is installed above the coil transmission sheet. The indicator light connection wire, button connection wire, and coil connection wire are tied with cable ties Tie it up to fully isolate the connecting wire from the transmission sheet. After adding the metal isolation baffle, the transmission sheet scratch rate is 0 and it has a long service life.
