[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 This utility model provides a technical solution: an explosion-proof permanent magnet isolation box, including an explosion-proof box body 1 and a box cover 4. Several fixed seats 2 are fixedly connected to the bottom side of the explosion-proof box body 1. A sealing groove 101 is opened on the top of the explosion-proof box body 1, and a sealing strip 6 is embedded in the sealing groove 101. When the box cover 4 is completely pressed against the top of the explosion-proof box body 1, the sealing strip 6 is compressed, forming good airtightness and explosion-proof sealing performance, preventing possible internal electric sparks from leaking into the external environment. The permanent magnet coupling system 7 is located inside the explosion-proof box body 1. The driving and driven ends achieve contactless transmission through magnetic field interaction. Since the explosion-proof box body 1 and the box cover 4 adopt high-strength materials and multiple sealing structures, they can effectively resist external explosion pressure and prevent internal energy leakage, ensuring operational safety.

[0017] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, a U-shaped clamping plate 3 is fixedly connected to the top of the explosion-proof enclosure 1. The enclosure cover 4 slides with the U-shaped clamping plate 3. A second dovetail groove 102 is provided on the top side of the explosion-proof enclosure 1 near the opening end of the clamping plate 3. A second dovetail block 52 slides within the second dovetail groove 102. An L-shaped connecting plate 5 is fixedly connected to the second dovetail block 52. A first dovetail block 53 is fixedly connected to the vertical end of the connecting plate 5. A third dovetail groove 302 and a first dovetail groove 401 that mate with the first dovetail block 53 are respectively provided on the clamping plate 3 and the enclosure cover 4. The first dovetail groove 401 is aligned with and inserted into the first dovetail block 53. At the same time, the first dovetail block 53 is also inserted into the first dovetail block 53. The third dovetail groove 302 is used for lateral positioning; a U-shaped groove 501 is provided on one side of the vertical end of the connecting plate 5, and a second stud 10 passing through the U-shaped groove 501 is fixedly connected to the clamping plate 3 to limit and assist in fixing; a groove 301 is provided on the side of the clamping plate 3 away from the second stud 10, and a side plate 51 that mates with the groove 301 is fixedly connected to the connecting plate 5.

[0018] Working principle: In use, first, align the box cover 4 with the U-shaped plate 3 and slide it into the appropriate position along the U-shaped plate 3. Then, align the first dovetail block 53 with the third dovetail groove 302 and the second dovetail block 52 with the second dovetail groove 102. Insert the L-shaped connecting plate 5 until the U-shaped groove 501 engages with the second stud 10 to limit and assist in fixing. At this time, the first dovetail block 53 engages with the third dovetail groove 302 and the first dovetail groove 401, and the second dovetail block 52 engages with the second dovetail groove 102 to achieve lateral positioning. At the same time, the side plate 51 is inserted into the groove 301 and initially positioned by the first stud 8 passing through the positioning hole 5101.
