[0024] By adopting the above technical solution, the protective tube is provided to achieve penetration and internal and external fixed installation.

[0025] Compared with the prior art, the invention has the following beneficial effects: the impact-resistant mining intrinsically safe switch can

[0026] (1) This case solves the problem that the shell of the intrinsically safe mine switch in the above solution does not have corresponding anti-impact facilities by setting up: protective tube and protective pad in the base protection structure. Although the shell is hard, after being impacted, its internal parts are easily damaged by the vibration of the impact, affecting its use. When the impact intrinsically safe mine switch body is installed inside the connection frame, the operator connects the protective tube with the protective pad and the installation plate to wrap and protect the intrinsically safe mine switch body installed inside the protective tube, and uses the protective pad set to provide preliminary buffering protection for the impact force generated. When the impact force is transmitted to the surface of the protective tube, the protective tube will diffuse the transmission force to provide anti-impact protection for the internal intrinsically safe mine switch;

[0027] (2) The heat dissipation holes, connection frame, filling water and epoxy resin are arranged in the base protection structure and the placement limit structure, so as to solve the problem that the heat generated inside the intrinsically safe switch during use is not easy to dissipate, and the internal parts are easily malfunctioned due to excessive temperature. When the heat generated during the use of the mining intrinsically safe switch body is absorbed and diffused by the epoxy resin, when the heat is absorbed and diffused, it is transferred to the connection frame and the filling water. At this time, the connection frame and the filling water quickly absorb the transferred heat for heat exchange processing, and the external air flow passes through the heat dissipation holes to exchange and carry out the heat diffused inside the protective tube, thereby achieving efficient heat dissipation for the intrinsically safe switch;

[0028] (3) The base protection structure is provided with: mounting plate, connection limit groove, guide connection groove, protection tube and connection rod, so as to facilitate the quick installation and later disassembly of the protection tube. When the protection tube needs to be disassembled, the operator uses the operating handle to rotate the protection tube to drive the connection rod to connect the connection limit groove and the guide connection groove. When the force is rotated, the protection tube is separated from the mounting plate by force, and the placed mining intrinsically safe exchange body can be quickly placed and taken out;

[0029] (4) By setting: placing a limit structure, the problem of the intrinsically safe type of mine switch body being placed and installed inside the base protection structure and shaking due to impact force is solved. When the intrinsically safe type of mine switch body needs to be installed inside the installation plate, the operator slides the intrinsically safe type of mine switch body and the connecting plate through the connecting slider and the connecting groove. At this time, the intrinsically safe type of mine switch body is limited and installed between the connecting plates, and the spring rod and the installation spring set in the limit structure are placed to play the role of installation elastic recovery limit for the intrinsically safe type of mine switch body, which also avoids the shaking and displacement of the intrinsically safe type of mine switch body due to impact force.

When 4 connecting limit grooves are opened through the above structure, it not only reflects the connecting limit property of the above structure, but also reflects the equidistant distribution property of the above structure. When 4 connecting limit grooves are opened through the above structure, it reflects the practicality of the above structure and the superposition with the guiding connecting groove 103. When the connecting limit grooves 102 are opened in a ring array with respect to the mounting plate 101, the axial and longitudinal axis symmetry of the above structure is reflected.

[0042] The above scheme further connects the limit groove 102 to the protective tube 105 through a connecting rod 104 for rotation and limiting connection. The overall shape of the protective tube 105 is a cylindrical structure, and the protective tube 105 is made of metal material. When the overall shape of the above-mentioned parts is a cylindrical structure, it not only reflects the wrapping property of the above-mentioned parts, but also reflects the ventilation and heat dissipation property of the above-mentioned parts. When the overall shape of the above-mentioned parts is a cylindrical structure, it also reflects the wrapping protection of the above-mentioned parts.
