Wherein, the diapire edge of stretching out outside wall box of described sand-proof lid is provided with heat dissipation ventilation hole.
Wherein, described first lockhole and the second lockhole are about the central cross axial symmetry of chamber door.
Further, the left surface top of described casing and right flank bottom have convection type dehumidifying hole, and described convection type dehumidifying hole is removably provided with dust storm screen pack.
Further, the surrounding of described opening is provided with the seal groove coordinated with the periphery of described chamber door, and described seal groove surface is provided with sealing strip, and described chamber door is closed rear described chamber door medial surface and is pressed together on formation sealing on sealing strip.
Preferably, described seal groove is L shape groove.
Preferably, described sealing strip is bellows seal bar; Described sealing strip can also be rubber weather strip.
Beneficial effect of the present invention is:
1, by arranging the one-touch bayonet socket lock of door lock, the first lockhole, the second lockhole and correspondence in the middle part of chamber door, realize 3 lockings of terminal box, avoid terminal box chamber door to close for a long time cause in process chamber door distortion, rake angle and poorly sealed situation, cost is low and simple to operate, easy to maintenance;
2, by arranging sand-proof lid, water suction barrier material bag and convection type dehumidifying hole, the anti-towards sand prevention ability of terminal box is improved further;
3, by arranging the seal groove coordinated with the periphery of chamber door around opening, the surface of seal groove arranges sealing strip, and rainwater can be discharged along seal groove, plays the effect preventing dust from entering and prevent rainwater from infiltrating.
