[0029] like Figure 2 As shown in the preferred embodiment of this utility model, the explosion-proof motor 1 includes: a housing 11, a front cover 12, a rear cover 13, a screw 14, a cable outlet screw hole 15, and an explosion-proof cable outlet nut 16. The housing 11 is disposed between the front cover 12 and the rear cover 13. The reducer assembly 4 is mounted on the front cover 12, the explosion-proof brake 3 is mounted on the rear cover 13, and the integrated explosion-proof controller 2 is mounted on the upper part of the front cover 12 and the rear cover 13. The front cover 12 and the rear cover 13 are both made of ZL105. The cable outlet screw hole 15 is disposed on the side of the front cover 12. The cable outlet screw hole 15 and the explosion-proof cable outlet nut 16 are configured to cooperate. The front cover 12 and the rear cover 13 are connected on the outside by the screw 14, and there are four screws 4.
[0030] Both the front cover 12 and the rear cover 13 are made of ZL105, and their thickness exceeds the relevant requirements of the corresponding explosion-proof equipment category. The front cover 12 is provided with a cable outlet screw hole 15 on the side. The front cover 12 and the rear cover 13 are directly connected on the outside by four screws 14, which greatly reduces the connection channels between the inside and outside of the explosion-proof motor 1, thereby improving the explosion-proof safety guarantee.
[0031] like Figure 3As shown in the preferred embodiment of this utility model, the integrated explosion-proof controller 2 includes: a housing 21, a cover 22, screws 23, a micro switch 24, a lead screw 25, a collision nut 26, a control main board 27, a power switch 28, a terminal block 29, an explosion-proof output coil 210, and an explosion-proof output bolt 211.
