Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0017] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model proposes a dust-proof device for instruments for engineering cost, including a mounting base 1, a hook 2, a rotating base 3, a protective structure 4 and an instrument structure 5. The hook 2 is arranged on the mounting base 1, the rotating base 3 is rotatably arranged on the mounting base 1, the protective structure 4 is fixed on the rotating base 3, and the instrument structure 5 is fixed on the rotating base 3. The protective structure 4 includes a protective cover 6, an adjustment window 7, a slide 8 and a sealing plate 9. The protective cover 6 is fixed on the rotating base 3, the adjustment window 7 opening is arranged on the protective cover 6, the slide 8 is fixed on the protective cover 6, and the sealing plate 9 is slidably arranged on the slide 8. The sealing plate 9 is arranged in an arc shape and the sealing plate 9 covers the adjustment window 7.
[0018] like Figure 1 and Figure 3 As shown, the instrument structure 5 includes an instrument host 10, a lens 11, a protective cover 12, a lens 2 13 and a protective cover 2 14. The instrument host 10 is fixed on the rotating seat 3, and the instrument host 10 is entirely wrapped by the protective cover 6. The lens 11 passes through the protective cover 6 and is fixed on the instrument host 10. The protective cover 12 is snap-connected to the lens 11. The protective cover 12 is made of rubber material. The lens 2 13 passes through the protective cover 6 and is fixed on the instrument host 10. The protective cover 2 14 is snap-connected to the lens 2 13.
