Folding canopy

Abstract

The present utility model relates to a folding tent support structure, comprising stakes and a canopy frame. The orthogonal projection of the canopy frame includes a quadrilateral and four triangular structures, each side of which is formed by linkages interconnected at two midpoints. The stake is further equipped with an expansion frame that can be linked to the canopy frame, expanding the support around the periphery of the canopy and significantly increasing the coverage area of the tent.

What is claimed is: 
     
         1 . A folding canopy, comprising 4 support rods and a canopy frame. The canopy includes a quadrilateral and four triangular structures, with each side of the quadrilateral and triangles formed by interconnecting linkages at two midpoints. The linkages on each side of the quadrilateral are respectively hinged together at the end portions through upper and lower bridging components, while the end portions of the linkages on the two sides of each triangular structure are hinged to the corresponding upper and lower bridging components, with the other end corresponding to being hinged on the fixed seat at the top of the support rod and sliding sleeve on the support rod's sliding seat. It is characterized in that: between the fixed seat and the sliding seat of the support rod, there is an expansion frame that can be linked to the canopy frame to expand and collapse. The expansion frame is composed of a long rod and a short rod, with one end of the long rod hinged on the fixed seat and the other end supported by the short rod at an inclined angle; the short rod is hinged on the sliding seat at one end and hinged on the long rod at the other end to support the long rod. 
     
     
         2 . The folding canopy as claimed in  claim 1 , a folding tent support structure, characterized in that: the orientation angle of the expansion frame hinged on the fixed seat and sliding seat is parallel to the centerline of the triangle. 
     
     
         3 . The folding canopy as claimed in  claim 1 or 2 , a folding tent support structure, characterized in that: the fixed seat is formed with a cylinder sleeve for securing to the top of the stake, two hinge slots with a 60-degree angle for hinging the linkages of the two sides of the triangle, and a hinge slot for hinging the long rod of the expansion frame; the hinge slots are formed on the upper and lower surfaces of the cylinder sleeve, and the lower surface of the cylinder sleeve is formed with a locking groove; the sliding seat has a through-hole for the stake to pass through, and the surface is formed with hinge slots corresponding to the fixed seat, and at the corresponding position of the locking groove, there is a self-locking latch; the self-locking latch, under the action of the torsion spring force, always maintains the tendency of the hooked end to engage the locking groove. 
     
     
         4 . The folding canopy as claimed in  claim 1 , a folding tent support structure, characterized in that: the canopy frame further includes a cone support frame, which is composed of four upper end-hinged cone support rod components, and the lower end of the cone support rod components is correspondingly hinged on the lower bridging components in the quadrilateral. 
     
     
         5 . The folding canopy as claimed in  claim 4 , a folding tent support structure, characterized in that: the upper end of the four cone support rod components in the cone support frame is hinged on a plastic cap, and the bottom surface of the plastic cap is evenly distributed with four hinge plates or hinge slots. 
     
     
         6 . The folding canopy as claimed in  claim 1 , a folding tent support structure, characterized in that: the ground end of the stake is provided with a foot pad, and the foot pad is formed with nail holes and a transverse hole, with a crossbar inserted in the transverse hole. 
     
     
         7 . The folding canopy as claimed in  claim 1 or 6 , a folding tent support structure, characterized in that: the stake is of a double-section detachable structure, including a small-diameter pipe section and a large-diameter pipe section, with the small-diameter pipe inserted into the large-diameter pipe. The inner side of the small-diameter pipe on one side of the insertion and matching section is embedded with a V-shaped spring ball to form a locking relationship between the two pipe sections; and a ring sleeve is fixed on the small-diameter pipe near the insertion section, and the end of the ring sleeve is integrally connected to a pressure plate, the pressure plate corresponding to the position of the V-shaped spring ball, which can press the V-shaped spring ball to release the lock.
