[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, this explosion-proof sewage pump includes a pump body 1, a pump cover 2, and a connecting chamber 3 for connecting the pump body 1 and the pump cover 2. The pump cover 2 is provided with several support seats 4, and the support seats 4 are provided with a wiring chamber 5 for installing wiring. A vertically arranged screw 6 is provided at the center of the wiring chamber 5. A wiring slide 7 is provided on one side of the wiring chamber 5. A pressure plate 8 is provided at the bottom of the wiring chamber 5. A fixing block 9 is provided at one end of the pressure plate 8. The fixing block 9 slides on the wiring slide 7.

[0017] When installing the wiring, the copper wire protruding from the front end of the wiring is usually bent into a circle and then put on the screw 6. Alternatively, for wiring with a conductive ring at the front end, the conductive ring can be put directly on the screw 6 during installation, and then the wiring is inserted along the wiring slide 7 so that the wiring abuts against the fixing block 9.

[0018] Preferably, the screw 6 is also provided with a pressure plate 2 10 symmetrically arranged with pressure plate 1 8, and a fixing block 2 11 symmetrically arranged with fixing block 1 9 is provided at one end of pressure plate 2 10. The copper wire or conductive ring at the front end of the wiring is clamped by the pressure plate 2 10 abutting against pressure plate 1 8.

[0019] Preferably, the second pressure plate 10 is provided with a nut 12 that is axially connected to it. The second pressure plate 10 is provided with a disc-shaped rotating groove 13. The nut 12 is provided with a rotating part 14 that is installed in conjunction with the rotating groove 13. The rotating part 14 has the same shape as the rotating groove 13. By turning the nut 12, the nut 12 pushes the second pressure plate 10 toward the first pressure plate 8.

[0020] Preferably, a slot 15 is provided on the opposite side of the pressure plate 18 and the pressure plate 10. An elastic plate 16 is provided outside the slot 15. A connecting rod 17 is provided between the slot 15 and the elastic plate 16. One end of the connecting rod 17 extends into the slot 15, and a mutual limiting part 18 is provided on both the slot 15 and the elastic plate 16. After the nut 12 is turned, the elastic plate 16 will abut against the two sides of the copper wire or the conductive ring respectively. At this time, if the nut 12 is turned further, the elastic plate 16 will be compressed, and the connecting rod 17 will enter the slot 15.

[0021] Preferably, the connecting rod 17 is provided with an elastic element 19 with an elastic reset function, which applies pressure to the elastic plate 16 through elastic reset, so that the elastic plate 16 makes closer contact with the copper wire or conductive ring.

[0022] Preferably, the fixing block is provided with a pressing part 20 of soft material. The opposite side of the pressing part 20 is arc-shaped. When the elastic plate 16 abuts against the copper wire or conductive ring, the pressing part 20 will tighten the connection and reinforce the gap between the connection and the connection through deformation.

[0023] Preferably, the support base 4, wiring compartment 5, screw 6, wiring slide 7, pressure plate 1 8, fixing block 1 9, pressure plate 2 10, fixing block 2 11, nut 12, rotating groove 13, rotating part 14, slot 15, elastic plate 16, connecting rod 17, limiting part 18, elastic element 19, and pressing part 20 together constitute the wiring mechanism, which is used for all wiring terminals of this explosion-proof sewage pump.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0025] Although this document frequently uses terms such as pump body 1, pump cover 2, connecting chamber 3, support base 4, wiring chamber 5, screw 6, wiring slide 7, pressure plate 1 8, fixing block 1 9, pressure plate 2 10, fixing block 2 11, nut 12, rotating groove 13, rotating part 14, slot 15, elastic plate 16, connecting rod 17, limiting part 18, elastic element 19, and extrusion part 20, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
