Specific Embodiments

[0015] Referring to Figure 1 、 Figure 2 and Figure 3 , an instrument protection box of the present utility model includes a box body 1, a box cover 2, a sealing ring 3, a wire passing hole 4, a flexible sealing sleeve 5, a flexible sealing ring 6 and a tightening belt 7. The box cover 2 is provided at the upper end of the box body 1, a sealing ring 3 is provided between the box cover 2 and the box body 1, the wire passing hole 4 is provided at the lower end of the box body 1, the flexible sealing sleeve 5 is provided at the lower end of the wire passing hole 4, the flexible sealing ring 6 is provided inside the lower end of the flexible sealing sleeve 5, and the tightening belt 7 corresponding to the flexible sealing ring 6 is provided on the flexible sealing sleeve 5.

[0016] The outer peripheral surface of the flexible sealing sleeve 5 is provided with loop belts 8 arranged at intervals in a circumferential shape, and a space for the tightening belt 7 to pass through is provided between the loop belts 8 and the flexible sealing sleeve 5.

[0017] A heat dissipation plate 9 that divides the inside of the box body 1 into an instrument chamber 11 and a heat dissipation chamber 12 is provided inside the box body 1. Heat dissipation fins 10 located in the heat dissipation chamber 12 are provided on the heat dissipation plate 9. A fan 13 is provided at the bottom of the heat dissipation chamber 12, and a heat dissipation window 14 is provided on the upper side surface of the heat dissipation chamber 12.
