[0029] Example 1:

[0030] This embodiment provides an explosion-proof junction box, including:

[0031] The first box body 1 has a first storage slot 11 inside. The first box body 1 has a first connecting half tube 12 at both ends along the X direction, and the first connecting half tube 12 has a first internal threaded groove 13 inside.

[0032] The second box 2 has a second storage slot 21 inside. The two ends of the second box 2 along the X direction are respectively provided with a second connecting half tube 22, and the second connecting half tube 22 is also provided with a second internal thread groove 23.

[0033] A number of fastening screws 4 are used to connect and assemble the first housing 1 and the second housing 2 together along the Z direction;

[0034] Limiting member 3 is movable along the X direction and is disposed on the first box 1 to limit the fastening screw 4 along the Z direction;

[0035] When the first box 1 and the second box 2 are assembled together, the first connecting half tube 12 and the second connecting half tube 22 are assembled together and used to connect with the cable conduit.

[0036] In this technical solution, the first box 1, the second box 2, and the limiting member 3 are all made of metal. During installation and use, the external threaded section of the cable conduit is inserted into the first internal thread groove 13 of the first connecting half-pipe 12. Then, the second box 2 is placed on top of the first box 1, and the other half of the external threaded section of the cable conduit is inserted into the second internal thread groove 23. Finally, the first box 1 and the second box 2 are securely connected together using the fastening screws 4, thus achieving the installation and use of the explosion-proof cable box. Through the above structural design, the use of a split-type structure makes the installation and use of the explosion-proof cable box more convenient and faster, and improves work efficiency.

[0037] By setting a movable limiting member 3 on the second box 2, the limiting member 3 abuts against the head of the assembled fastening screw 4, which can limit the fastening screw 4 along the Z direction to prevent the fastening screw 4 from loosening due to long-term use, thereby ensuring that the first box 1 and the second box 2 can maintain a tight connection, thus ensuring that the explosion-proof wiring box has good sealing performance and improving the safety of use.

[0038] In summary, by designing the explosion-proof wiring box into a split structure, the installation and use of the explosion-proof wiring box are made more convenient and quick. At the same time, a limiting member 3 is set on the second box body 2 to abut against the fastening screw 4 in the Z direction, thereby limiting the fastening screw 4 and preventing it from loosening, thus ensuring good sealing of the explosion-proof wiring box and improving safety.

[0039] Example 2:

[0040] This embodiment provides an explosion-proof junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0041] Furthermore, the first housing 1 includes a plurality of first mounting holes 14, which are disposed on the first housing 1 along the Z direction;

[0042] The second box 2 includes:

[0043] Slide 25, slide 25 is formed on the second box 2 and is arranged along the X direction;

[0044] A plurality of second mounting holes 24 are provided, which pass through the second housing 2 along the Z direction;

[0045] The fastening screw 4 passes through the second mounting hole 24 and connects to the first mounting hole 14, and the limiting member 3 is movable in the slide groove 25 along the X direction.

[0046] In this technical solution, the second mounting hole 24 passes through the slide groove 25. The fastening screw 4 is inserted into the second mounting hole 24 along the Z direction and connects with the first mounting hole 14 to achieve a fastening connection between the first housing 1 and the second housing 2. The head of the fastening screw 4 is located in the slide groove 25. Furthermore, the second mounting hole 24 can be designed as a countersunk hole structure, allowing the head of the fastening screw 4 to be hidden in the second mounting hole 24. Then, by inserting the limiting member 3 into the slide groove 25, the limiting member 3 abuts against the head of the fastening screw 4, limiting the fastening screw 4 and effectively preventing it from loosening.

[0047] Furthermore, the limiting member 3 also includes a locking magnetic block 31, which is disposed on the limiting member 3 for adsorption and fixation to the second box 2. Through this structural design, the limiting member 3 is fixed by adsorption and fixation of the locking magnetic block 31 and the second box 2, effectively preventing the limiting member 3 from shifting, making the structure more stable and reliable.

[0048] Example 3:

[0049] This embodiment provides an explosion-proof junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] Furthermore, the second housing 2 is provided with a weight-reducing groove 26 arranged along the Z direction. By providing the weight-reducing groove 26, the material input of the second housing 2 is effectively reduced while ensuring structural strength, thereby reducing production costs and improving economic efficiency.

[0051] Example 4:

[0052] This embodiment provides an explosion-proof junction box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] The second box 2 includes a sealing groove 27, which is disposed on the end face of the second box 2 facing the first box 1 along the Z direction;

[0055] The sealing protrusion 15 is adapted to be inserted into the sealing groove 27.

[0056] In this technical solution, by setting a matching and interlocking sealing protrusion 15 and sealing groove 27, the gap between the first box body 1 and the second box body 2 is a bent structure, effectively preventing dust and other particulate matter from entering the first storage slot 11 and the second storage slot 21, thus achieving a dustproof effect. Furthermore, a sealing gasket 5 is also provided in the sealing groove 27, and the sealing protrusion 15 abuts against the sealing gasket 5. The sealing gasket 5 is made of rubber, and the abutting action between the sealing gasket 5 and the sealing protrusion 15 enhances the sealing performance and improves the waterproof, dustproof, and explosion-proof effects.
