Description

Corner anti-collision device for hollow shutter glass Technical Field The utility model belongs to the technical field of hollow shutter glass, and particularly relates to a corner anti-collision device for hollow shutter glass. Background The hollow shutter glass is energy-saving glass, mainly comprises two layers of glass and a group of shutter fans, and realizes the operation of the shutter fans by controlling a closing device and a lifting device through magnetic force, so that the hollow shutter glass saves the use space, simultaneously, the glass door and window has good sun shading performance, the heat preservation performance of the hollow glass is improved, the indoor light environment is improved, and the hollow shutter glass is glass with various functions, high cost performance and environmental protection and energy saving. In the prior art, the problem of corner protection of hollow shutter glass has long been a technical bottleneck. In addition, although the hollow built-in shutter glass realizes basic functions through the silicone sealant and the winding device, the anti-collision performance of the glass corners is not specifically designed. The traditional protective structure adopts an external butt joint cover or a thin protective pad, and the protective structure is fixed on the outer side of the frame through bolts or adhesion, so that the installation is complicated, the thickness of the protective layer is limited, and the impact energy is difficult to effectively absorb. In addition, the problem that current protector ubiquitous does not laminate with the frame surface, exist the clearance between protection pad and the frame for example, lead to the protection effect unstable. Disclosure of utility model The utility model aims to provide a corner anti-collision device for hollow shutter glass, which aims to solve the problems in the background technology. The corner anti-collision device for the hollow shutter glass comprises a hollow shutter glass body and a corner anti-collision device, wherein the hollow shutter glass body comprises a frame, toughened glass and aluminum alloy shutters arranged on the inner side of the frame; The corner anti-collision device comprises an elastic protective sleeve and a reinforcing structure, wherein the elastic protective sleeve is sleeved at four corners of the frame, and the reinforcing structure is arranged in the elastic protective sleeve; The four corners of the frame are provided with L-shaped anti-collision grooves which enable the elastic sheath to be flush with the surface of the frame.
