Adopt the beneficial effect of above-mentioned further scheme to be make the intensity of whole shielding window higher, damping effect is better.
Further, above-mentioned damping diagonal brace mechanism comprises strut and sleeve, above-mentioned strut one end is hingedly mounted on protective shield, one end of above-mentioned strut other end grafting sleeve is inner, and coordinated with sleeve resilience by the spring be socketed on strut, above-mentioned sleeve is hingedly mounted on base away from the other end of strut.
Adopt the beneficial effect of above-mentioned further scheme to be that structure is comparatively simple, whole damping diagonal brace institution secure performance is higher, and damping effect is stronger.
Further, inlay in above-mentioned protective shield LED light source is installed.
Adopt the beneficial effect of above-mentioned further scheme to be supplement light source, be convenient to observe blasting process in test.
Further, the end face that above-mentioned protective shield deviates from damping diagonal brace mechanism is provided with transparent cover plate, and above-mentioned cover plate covers outside above-mentioned LED light source.
The beneficial effect of above-mentioned further scheme is adopted to be the situation effectively preventing LED light source may be damaged at blasting process.
Further, the end face of above-mentioned protective shield connection damping diagonal brace mechanism has T-shaped groove, in above-mentioned T-shaped groove, gusset plate is installed.
Adopt the beneficial effect of above-mentioned further scheme to be when blast process is stronger, the intensity of whole shielding window can be improved, ensure that it is not damaged.
Further, above-mentioned gusset plate is steel plate.
The beneficial effect of above-mentioned further scheme is adopted to be the structural strength promoting whole shielding window.
