Further, the thickness of described sealing strip 3 is 3cm～10cm.
Seen from the above description, the thickness of described sealing strip 3 is 3cm～10cm, sealing strip 3 is the thickest, the deflection that sealing strip 3 can be extruded is the biggest, the mismachining tolerance that can allow when contacting between sealing strip 3 with flange 11 is the biggest, sealing is the best, fully ensures that the effectiveness of the contact area of whole circle, good sealing effect between sealing strip 3 and flange 11.
Further, the material of described sealing strip 3 is foaming ethylene propylene diene rubber.
Seen from the above description, foaming ethylene propylene diene rubber has preferable pliability, and the amount that can be deformed is relatively big, fully ensures that the effectiveness of the contact area of whole circle, good sealing effect between sealing strip 3 and flange 11.
Further, described case lid 2 is hinged with casing 1, and the spacing between medial surface and the flange 11 of described casing 1 of described case lid 2 is equal to 0.5～0.8 times of described sealing strip 3 thickness.
Seen from the above description, after casing 1 is connected with case lid 2, sealing strip 3 be extruded after 0.5～0.8 times that thickness is the thickness before sealing strip 3 is extruded, rational in infrastructure, good sealing effect.
Further, the medial surface edge of described case lid 2 is provided with convex edge 21.
Seen from the above description, the medial surface edge of described case lid 2 is provided with convex edge 21, and dust and rainwater can play the effect of stop.
Further, the angle between described convex edge 21 and described case lid 2 medial surface is 85 °～95 °.
Seen from the above description, the angle between described convex edge 21 and described case lid 2 medial surface is 85 °～95 °, can effectively prevent dust especially rainwater from entering case lid 2 medial surface from the gap between case lid 2 and flange 11, and preventing dust rainwater is effective.
Further, the width of described convex edge 21 is 0.8cm～5cm.
Seen from the above description, the width of described convex edge 21 is 0.8cm～5cm, effectively prevents dust especially rainwater from entering case lid 2 medial surface from the gap between case lid 2 and flange 11, and preventing dust rainwater is effective.
Further, the distance between described flange 11 and described convex edge 21 is 0.2cm～1cm.
