Expanding-type frictional overturning wheel structure for louver with built-in double-layer hollow glass
The invention discloses an expanding-type frictional overturning wheel structure for a louver with built-in double-layer hollow glass, and belongs to the technical field of shading hollow glassware. The structure comprises a curtain sheet overturning shaft, an overturning wheel, and an overturning wheel seat. The structure is characterized in that the structure also comprises an overturning wheel shaft; the overturning wheel shaft is supported by the overturning wheel seat; the center of the overturning wheel shaft is provided with a curtain sheet overturning shaft mating hole; the curtain sheet overturning shaft mating hole is in inserting fit with the curtain sheet overturning shaft for fixing; the right end of the overturning wheel shaft forms an overturning wheel shaft limiting flange; the left side surface of the overturning wheel shaft limiting flange contacts with the right end face of the overturning wheel; the overturning wheel is disposed at the center of the overturning wheel shaft in a sleeve manner through an overturning wheel hole, and is corresponding to an overturning wheel storage cavity; the left end of the overturning wheel forms a limiting step, and the upper part of the right end of the overturning wheel is provided with an expanding groove; the left end of the front side wall of the overturning wheel seat and the left end of the rear side wall of the overturning wheel seat respectively form a limiting step convex block. The structure avoids the frictional damage of a curtain sheet overturning pulling rope, avoids rope-wheel friction damage of the curtain sheet overturning pulling rope, and protects an elevator rope, connected to the overturning wheel through a rope winding tongue plate, from being damaged.
