It is suitable for explosive and hazardous environments such as oil refining, storage, chemical industry, medicine, military industry, and military facilities. The joint surface between the wire box body and the cover is sealed with rubber, which has good sealing and strong waterproof performance. The explosion-proof wire box is used when the line is being laid or the cable is turning, the line length exceeds the specified length, or the line is uneven or the pipeline cannot be flat. At this time, a box needs to be added in the extra place to protect the cable from damage.

[0003] The electrical lines in explosion-proof places are all arranged in the threading tube, and the threading tube is connected to the threading box. The current threading box is equipped with more than two internal threaded ports, and the threading tube end is externally threaded. This connection method requires rotating either the threading tube or the threading box around the axis to achieve the purpose of installation and removal, which is very inconvenient, especially when replacing the threading box. The threading tube is fixed on a carrier such as a wall. During installation and removal, the threading box can only be rotated to tighten and remove the screw, which can easily damage the threading tube. Therefore, the applicant has made a useful design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] Reference example Figures 1 to 3 The sealing groove 21 is provided on the upper box body 1 and the lower box body 2 is provided with a sealing member 11 corresponding to the sealing groove 21, and the sealing member 11 is embedded in the sealing groove 21, so that the connection between the upper box body 1 and the lower box body 2 forms a sealed structure. By setting the upper box body 1 and the lower box body 2 as split-type, the disassembly of the threading tube from the upper box body 1 and the lower box body 2 is improved, and the external thread of the threading tube does not need to be loosened from the internal thread groove 31. Similarly, when installing the threading tube, it is only necessary to embed the external thread groove of the threading tube into the internal thread groove 31. When the upper box body 1 and the lower box body 2 are closed, the other half of the internal thread groove 31 is naturally embedded in the external thread groove of the threading tube, reducing the difficulty of installation and disassembly. When the line is wired in the first concave cavity 12 or the second concave cavity 22, due to the split structural design, the field of view is wide, the installation time is reduced, and the work efficiency is improved.

[0025] It is worth mentioning that the upper box body 1 and the lower box body 2 are provided with at least two pipe semi-apertures 3, which correspond to each other and form a hole for wrapping the threading tube. The pipe semi-aperture 3 is provided with an internal thread groove 31, which is used in conjunction with the external thread groove of the threading tube, or is connected with an explosion-proof cable connector;

[0026] It is worth mentioning that the upper box body 1 and the lower box body 2 are provided with a plurality of mounting holes 4, which correspond to each other. The mounting holes 4 are provided with fastening screws 5, so that the upper box body 1 and the lower box body 2 are connected and fixed. The mounting holes 4 are used in conjunction with the fastening screws 5. The fastening screws 5 make the semi-apertures 3 of the pipe fittings abut against each other, so that the sealing member 11 is tightly embedded in the sealing groove 21, thereby ensuring the sealing of the connection.

[0027] It is worth mentioning that the detachable arrangement is a fastening screw 5;

[0028] It is worth mentioning that the upper box body 1 is provided with a first concave cavity 12, and the lower box body 2 is provided with a second concave cavity 22. The line led out of the threading tube is connected in the first concave cavity 12 or in the second concave cavity 22. When the upper box body 1 and the lower box body 2 abut against each other, a relatively closed space is formed between the first concave cavity 12 and the second concave cavity 22, thereby preventing sparks generated at the internal line connection from affecting external equipment, and preventing external dust and water droplets from entering the first concave cavity 12 and the second concave cavity 22;

[0029] It is worth mentioning that the sealing member 11 is arranged on the top end surface of the first cavity 12, and the material of the sealing member 11 is set to be silicone.
