Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of square optical instrument light shield, including rectangular cover 11, it is described
Connecting plate 4 is provided with the upside of the both ends of rectangular cover 11, the both ends inwall of rectangular cover 11 is hinged with left shadow shield 10 and right shadow shield 9, square
The upper end inwall of shape cover 11 is hinged with shadow shield 7, and the upper end of rectangular cover 11 and both ends sidewall upper are provided with limiting plate 8, the left side
Shadow shield 10 and the corresponding position of limiting plate 8 of right shadow shield 9 and upper shadow shield 7 are respectively arranged with left and right magnet 1 and upper magnet 6,
The position of upper magnet 6 on the corresponding upper shadow shield 7 of left shadow shield 10 and right shadow shield 9 is provided with fixed magnet 5, the He of upper magnet 6
Fixed magnet 5 is different in nature each other, and steel disc is provided with limiting plate 8, connecting hole 3 and inserting groove 2, rectangular cover are provided with connecting plate 4
11 be working of plastics.
The utility model realizes connection installation function, passes through the left shadow shield of hinged design by the design of connecting plate 4
10th, right shadow shield 9 and upper shadow shield 7, left shadow shield 10, right shadow shield 9 and the Activities Design of upper shadow shield 7 is realized, passes through limit
The design of position plate 8 and corresponding left and right magnet 1 and upper magnet 6, realizes left shadow shield 10, right shadow shield 9 and upper shadow shield 7
Opening regular worker, then the design by upper magnet 6 and fixed magnet 5 realizes left shadow shield 10, right shadow shield 9 and upper screening
Fixing function when tabula rasa 7 closes, opened by left shadow shield 10, right shadow shield 9 and upper shadow shield 7 and realize shade function, led to
