AI Technical Summary

Technical Problem

In extra-large louvered insulated glass, the existing lifting devices are laborious and inconvenient to operate. In particular, the traditional under-mounted counterweight structure results in the inner controller being in a high position, the outer controller being inconvenient to operate, and the lifting ropes being laborious.

Method used

The internal and external controllers are connected by magnetic attraction. The internal controller has a lower counterweight. The upper counterweight is added through a combination of lifting rope assembly, upper and lower steering wheel assembly, corner seat and movable pulley assembly. The counterweight is offset to form a lifting rope assembly with multiple force application points. Combined with the movable pulley assembly and magnetic attraction device, the position of the operating handle is optimized and friction is reduced.

Benefits of technology

It achieves more effortless and convenient operation of raising and lowering Venetian blinds of the same size, conforms to ergonomics, improves user experience, and reduces operating stroke and starting thrust.

Abstract

The application provides a lightweight lifting device for super-large size louver hollow glass, which comprises a plurality of lifting rope groups, each of which comprises a lifting rope, two upper redirecting wheel assemblies and two lower redirecting wheel assemblies; each of the upper redirecting wheel assemblies comprises an upper redirecting wheel seat and an upper redirecting wheel, and each of the lower redirecting wheel assemblies comprises a lower redirecting wheel seat and a lower redirecting wheel; the upper redirecting wheel seat and the lower redirecting wheel seat are also provided with rope passing holes; one end of the lifting rope is fixed to a corner seat, the other end of the lifting rope is wound downward around a movable pulley, then is wound upward around a fixed pulley in the corner seat, then is passed downward through the rope passing hole of the proximal upper redirecting wheel, then is sequentially passed upward through the rope passing holes of the proximal lower redirecting wheel and the distal lower redirecting wheel, is redirected by the distal upper redirecting wheel, is passed downward through the proximal upper redirecting wheel and the fixed pulley, and is finally fixed to the movable pulley assembly. The lifting device provided by the application has the advantages of labor saving and convenient operation, and can greatly improve the control experience of the user.
