[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] Reference Figure 1 - Figure 3The utility model provides an embodiment: a wiring structure of an explosion-proof solenoid valve, including a solenoid valve housing 1, which is used to maintain the stability of the internal structure. A conductive tube 2 is fixedly connected to the outer side of the solenoid valve housing 1, which can export electrical signals. A protective shell 3 is fixedly connected to the outside of the conductive tube 2. A plurality of wiring holes 4 are opened on the outside of the protective shell 3, through which the lines to be wired can be inserted. A plurality of fixing components are arranged on the top of the protective shell 3, which can firmly fix the lines inside the device. The fixing components include a rotating twist 5, a threaded sleeve 6, and an extrusion block 7. The outer thread of the threaded sleeve 6 is connected to the inside of the protective shell 3, and the bottom of the rotating twist 5 is fixedly connected to the top of the threaded sleeve 6. The inside of the sleeve 6 is slidably connected with an extrusion block 7, which can fix the circuit inside the device, the outside of the extrusion block 7 is slidably connected to the outside of the conductive block 8, and the outside of the extrusion block 7 contacts the inner wall of the wire insertion slot 9 for tightly fitting the circuit, and a plurality of conductive blocks 8 are fixedly connected to the top of the conductive tube 2 for deriving electrical signals, and wire insertion slots 9 are provided on the far sides of the plurality of conductive blocks 8, and a plurality of shells 10 are fixedly connected to the inside of the protective shell 3, and a rotating block 11 is rotatably connected to the inside of the shell 10, and a cross groove 12 is provided on the top of the rotating block 11, and a threaded block 13 is fixedly connected to the bottom of the rotating block 11, and an elastic component is provided inside the shell 10, which can provide elastic force for the structure at both ends.

[0021] The elastic component includes a spring 14, which is arranged inside the shell 10, one end of the spring 14 is fixedly connected to the bottom of the threaded block 13, and the other end of the spring 14 is fixedly connected to the top of the special-shaped block 15. The shell 10 is provided with a special-shaped block 15, and the outside of the special-shaped block 15 is slidably connected to the inner wall of the shell 10. The outside of the special-shaped block 15 contacts the outside of two squeezing balls 16. Two squeezing balls 16 are arranged inside the shell 10, and the outsides of multiple squeezing balls 16 contact the inside of the protective shell 3.

[0022] Compared with some existing technologies, the above content enables the device to apply pressure to the spring 14 during use so that the spring 14 applies pressure to the squeezing ball 16 through the special-shaped block 15, thereby solving the problem that the installation and disassembly steps of some devices during use easily cause squeezing deformation of the internal shape of the shell, affecting the use of the device.

[0023] Working principle: first align the line to be wired with the wiring hole 4, then slowly insert the line into the wiring hole 4, so that it enters the inside of the wire slot 9, and then rotate the rotating knob 5 so that the threaded sleeve 6 at the bottom of the rotating knob 5 is threadedly rotated inside the protective shell 3, and slowly descends during the rotation process, thereby driving the extrusion block 7 to move downward, so that the extrusion block 7 can steadily enter the line into the inside of the wire slot 9, so that the wires in the line are in close contact with the outside of the wire slot 9, so that the conductive tube 2 can transmit electricity to the line. When there is a problem inside the device, use a cross cone to align the cross slot 12 to rotate the rotating block 11. During the rotation of the rotating block 11, the threaded block 13 rotates inside the shell 10, so that the spring 14 is compressed and rotated, so that the spring 14 drives the bottom special-shaped block 15 to rotate and move, and during the movement of the special-shaped block 15, the extrusion ball 16 is squeezed, so that the extrusion ball 16 moves outward, so that the extrusion ball 16 is in close contact with the inside of the protective shell 3, thereby fixing the protective shell 3, and it can be released anyway.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
