[0023] Please see Figure 1-5 An explosion-proof electromagnetic brake includes: an electromagnetic brake body 1, a wiring structure 2 on the electromagnetic brake body 1, the wiring structure 2 including a terminal block 21 fixedly connected to the electromagnetic brake body 1, and a power cord 22 that can be plugged into the terminal block 21; a secondary connector 23 is fixedly installed on the outer surface of the power cord 22; a primary connector 26 is fixedly installed on the outer surface of the terminal block 21; a positioning cylinder 24 is fixedly installed on the side of the secondary connector 23 adjacent to the primary connector 26; a sealing ring 25 is provided between the terminal block 21 and the power cord 22; and a reinforcing component 3 is also provided on the terminal block 21; the terminal block 21 and the power cord 22 are connected... A groove for accommodating the sealing ring 25 is provided on the adjacent end face. The sealing ring 25 is made of rubber. The positioning cylinder 24 can be inserted into the main connecting seat 26. The inner ring size of the positioning cylinder 24 is larger than the outer ring size of the bolt 33, which can prevent the positioning cylinder 24 from affecting the bolt 33 from being screwed into the secondary connecting seat 23. The positioning cylinder 24 can also align the threaded hole on the secondary connecting seat 23 with the bolt 33. There are two secondary connecting seats 23. The number of main connecting seats 26 is the same as the number of secondary connecting seats 23. The upper end of the bolt 33 can pass through the main connecting seat 26, and the part of the bolt 33 that passes through the main connecting seat 26 can be threadedly connected to the secondary connecting seat 23.

[0024] The reinforcing component 3 includes a receiving seat 31 fixedly installed on the outer surface of the terminal block 21, a bolt 33 disposed in the internal cavity of the main connecting seat 26, and a nut 311 fixedly installed on the side wall of the inner cavity of the main connecting seat 26. A disc-shaped shaft 35 and a drive shaft 39 are rotatably mounted inside the receiving seat 31. A square rod 34 is fixedly installed on the side of the disc-shaped shaft 35, and the square rod 34 is slidably connected to the bolt 33. The bolt 33 is threadedly connected to the nut 311. A ring gear 310 is fixedly installed on the circular outer surface of the disc-shaped shaft 35. A gear ring 37 meshes with the ring gear 310. A bearing 36 is disposed on the side of the gear ring 37, and the gear ring 37 is rotatably connected to the receiving seat 31 through the bearing 36. Both ends of the drive shaft 39 are respectively fixedly mounted... Equipped with a columnar head 32 and a drive gear 38, the drive gear 38 also meshes with a gear ring 37. A limit block is fixedly installed at the end of the square rod 34, which is located inside the bolt 33. The gear ring 37 is provided with two annular meshing teeth, one of which is located on the outer surface of the gear ring 37 and the other is located on the inner surface of the gear ring 37. This design of the gear ring 37 can improve the flexibility of the overall structure and meet its transmission requirements, allowing the user to adjust the state of multiple bolts 33 at the same time. The upper surface of the columnar head 32 is on the same plane as the upper surface of the receiving seat 31, and the upper surface of the columnar head 32 is provided with a hexagonal socket that can be used with a hexagonal wrench, which facilitates the user to adjust the overall structure.

[0025] Working principle: A secondary connector 23 is fixed to the surface of the power cord 22, and a positioning cylinder 24 is fixed to the side of the secondary connector 23. After aligning the positioning cylinder 24 with the main connector 26 on the surface of the terminal block 21, the power cord 22 is inserted into the terminal block 21 of the electromagnetic brake body 1. Then, a hex wrench is inserted into the cylindrical head 32 to drive the cylindrical head 32 to rotate. The transmission shaft 39, which is fixedly connected to the cylindrical head 32, rotates synchronously inside the receiving seat 31. The drive gear 38 at the end of the transmission shaft 39 meshes with the outer annular meshing teeth of the gear ring 37. The gear ring 37 is rotatably connected to the receiving seat 31 using the bearing 36, and the inner annular meshing teeth of the gear ring 37 mesh with the disc shaft 35. The ring gear 310 meshes with the cylindrical head 32, so after the cylindrical head 32 rotates, the disc shaft 35 rotates synchronously. The square rod 34 fixed on the disc shaft 35 is also slidably connected to the bolt 33. The bolt 33 is threadedly connected to the nut 311 fixed inside the main connecting seat 26. After the disc shaft 35 drives the square rod 34 to rotate, the bolt 33 will be unscrewed from inside the main connecting seat 26 and then screwed into the threaded hole on the secondary connecting seat 23 to fasten the secondary connecting seat 23 to the main connecting seat 26. At this time, the sealing ring 25 between the power cord 22 and the terminal block 21 is squeezed, filling the gap between the power cord 22 and the terminal block 21 to ensure the sealing of the connection.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
