The utility model is described in further detail below with reference to fig. 1-6.

The embodiment of the utility model discloses a top collapse prevention structure of a foldable awning and the awning, which are mainly used for a supporting structure of the awning, and comprise a foldable awning bracket; the sunshade bracket is formed into an umbrella-shaped structure by connecting a ceiling bracket 1, a folding bracket 3 and four upright posts 4.

The ceiling bracket 1 is formed by hinging four connecting rods 12 through a first ceiling joint 11, an anti-collapse bracket 2 is arranged above the first ceiling joint 11 on the ceiling bracket 1, and the anti-collapse bracket 2 is formed by hinging four supporting rods 21 through a second ceiling joint 22; one of the support rods 21 is hinged to one of the links 12; a push rod 13 is fixedly connected between the first ceiling joint 11 and the second ceiling joint 22, and the push rod 13, the adjacent connecting rod 12 and the support rod 21 form a triangular support structure.

Further, the first ceiling joint 11 and the second ceiling joint 22 are connected by the design of the ejector rod 13 in a relatively fixed state, and in the unfolded state of the sunshade bracket, the double-layer support structure enables the sunshade to be more stable, the collapse-preventing bracket 2 provides upward tension force for the sunshade bracket 1 and forms a stable structure by triangular support, meanwhile, the protruding structure of the collapse-preventing bracket 2 can effectively disperse stress to a certain extent, and the situation that the center of the sunshade cloth and the middle position of the sunshade bracket 1 are easy to be inwards concave to form ponding under the impact of rainwater to weigh the load of the sunshade bracket 1 when the sunshade bracket is used in a rainy day is avoided.

The folding and unfolding structure of the foldable awning bracket is designed as follows: each upright post 4 of the four upright posts 4 is sequentially sleeved with a fixed connecting seat 41 and a sliding connecting seat 42 from top to bottom; the sliding connection seat 42 is slidably sleeved on the upright post 4 and moves up and down along the shaft of the upright post 4.

Wherein, to the spacing of sliding connection seat 42, the structure design is: the stand column 4 is provided with a limiting protrusion 43 at a certain height, a spring is arranged in the limiting protrusion 43, the limiting protrusion 43 is provided with a limiting spring which is extruded to shrink inwards of the stand column 4, an opening 421 is arranged at the top end face of the connecting seat, and the opening 421 is arranged downwards in a gradient manner to form a slope 422.

When the sliding connection seat 42 slides, the opening 421 is configured to let the limiting protrusion 43 be displaced when the sliding connection seat 42 moves upwards along the shaft of the upright 4, the slope 422 is configured to press the limiting protrusion 43 inwards to shrink and let the sliding connection seat 42 move in the upward movement process, when the sliding connection seat 42 slides to be dislocated with the limiting protrusion 43, the limiting protrusion 43 loses inward extrusion force, and pops up under the action of a spring, and the limiting protrusion 43 is propped against the bottom end surface of the sliding connection seat 42 in a protruding state so as to limit the downward movement of the sliding connection seat 42 along the shaft of the upright 4, thereby realizing the limitation of the downward movement of the sliding connection seat 42 in a unfolding state.

The folding bracket 3 is formed into a diamond structure by hinging a plurality of supporting rollers 31 in pairs; one of the diamond-shaped branches of the folding bracket 3 is fixed on the fixed connecting seat 41, and the other branch is fixed on the sliding connecting seat 42.

The rollers 31 of the folding bracket 3 are hinged by a hinge, and the hinge comprises a first hinge part 32 and a second hinge part 33, wherein the front ends of the first hinge part 32 and the second hinge part 33 are provided with pin holes 34. When in use, the pin holes 34 of the first hinge part 32 and the pin holes 34 of the second hinge part 33 are overlapped, and the diamond connection between the supporting rollers 31 is completed by using pin bolts.

The connecting rod 12 is hinged with a first top support rod 121 and a second top support rod 122 away from the first ceiling joint 11, the first top support rod 121 is connected with the fixed connecting seat 41, and the second top support rod 122 is connected with the sliding connecting seat 42.
