Foldable food cover

Abstract

The utility model is related to the technology field of food cover, in particular to foldable food cover by adding folding components to the supporting rod for easy storage. The simple connecting structure is convenient to operate, safe and practical to reduce the storage size of the food cover effectively and improve the portability significantly. There are a top post, sliding sleeves, four sets of elastic spokes and four sets of folding support rods, wherein the sliding sleeves can be sleeved on the top post in an up-and-down sliding manner; the tops of the four sets of folding support rods are symmetrically and rotatably mounted on the top of the top post respectively; the outer ends of four sets of elastic spokes are hinged with four sets of folding support rods respectively, and inner ends of the four sets of elastic spokes are hinged with sliding sleeves, wherein each folding support rod also comprises an upper support rod, a folding component, a lower support rod and a cylindrical pin, the top end of the upper support rod is rotatably connected with the top of the top post, and the head of the folding component is inlaid and connected with the bottom end of the upper support rod.

1 . A foldable food cover featured by the composition of a top post ( 1 ), sliding sleeves ( 2 ), four sets of elastic spokes ( 3 ) and four sets of folding support rods, wherein the sliding sleeves ( 2 ) can be sleeved on the top post ( 1 ) in an up-and-down sliding manner. The tops of the four sets of folding support rods are symmetrically rotatably mounted on the tops of the top posts ( 1 ), the outer ends of the four sets of elastic spokes ( 3 ) are respectively connected with the four sets of folding support rod hinges, the inner ends of the four sets of elastic spokes ( 3 ) are all hinged connected with the sliding sleeve ( 2 ), wherein each folding support rod further comprises an upper support rod ( 4 ), a folding component ( 5 ), a lower support rod ( 6 ) and a cylindrical pin ( 7 ), the top of the upper support rod ( 4 ) is rotatably connected with the top of the top post ( 1 ), the head of the folding component ( 5 ) is inlaid with the bottom end of the upper support rod ( 4 ), the tail of the folding component ( 5 ) is rotatably connected with the lower support rod ( 6 ) by means of the cylindrical pin ( 7 ), the lower support rod ( 6 ) can rotate by taking the cylindrical pin ( 7 ) as the center of the circle, and there are yarns laid fixedly between the four sets of folding support rods. 
     
     
         2 . A foldable food cover as described in  claim 1 , featured by the tail of the folding component ( 5 ) extends to limit the rotation angle of the lower support rod ( 6 ) from 0° to 180°.
