Description

Technical Field

[0001] The invention relates to camping supplies, in particular to an awning rack. Background Art

[0002] Camping tents are generally divided into tents and awnings. The difference between the two lies in the upper and lower position relationship between the tarpaulin and the pole. The tent includes a tent frame (pole) and a tarpaulin, and the tarpaulin is connected under the tent frame. The awning includes an awning frame (pole) and a tarpaulin, and the tarpaulin is covered on the awning frame.

[0003] The existing awning frame includes a top connection seat and a plurality of frame rod groups. The frame rod group includes a column, a awning rod group and a strut. A fixed seat is fixedly provided on the top of the column, and a sliding seat is provided on the column. The awning rod group includes a first awning rod and a second awning rod, the inner end of the first awning rod is rotatably connected to the top connection seat, the inner end of the second awning rod is rotatably connected to the outer end of the first awning rod, and the outer end of the second awning rod is rotatably connected to the fixed seat. The lower end of the strut is rotatably connected to the sliding seat, and the upper end is rotatably connected to the second awning rod. A scissor mechanism is also provided between the fixed seat and the sliding seat of each adjacent column, and the scissor mechanism includes at least one scissor unit. In order to keep the awning frame in the unfolded state, a locking mechanism needs to be provided between the sliding seat and the column of each column. Therefore, it has the following shortcomings: first, when folding, the locking mechanism of each column needs to be loosened, the steps are cumbersome, and it is inconvenient to open or fold; second, when opening, it is necessary to push the slide seat up relative to each column. In order to ensure that multiple columns push the slide seats up synchronously, multiple people may be required to operate together, and it is necessary to confirm whether each locking mechanism is in a locked state, the steps are cumbersome, and it is inconvenient to open or fold.

[0004] In view of the above shortcomings, some people have proposed solutions, such as:

[0005] CN207714893U adds a bottom connection seat to the original awning frame, and a rotating rod is rotatably connected between each bottom connection seat and the first awning rod. One end of the rotating rod is rotatably connected to the bottom connection seat, and the other end is rotatably connected to the first awning rod. A telescopic rod assembly is provided between the top connection seat and the bottom connection seat, and a tension spring is provided between the bottom connection seat and the top connection seat. The awning frame is assisted in unfolding by the tension of the tension spring, and the distance between the bottom connection seat and the top connection seat is limited by the telescopic rod assembly being in the shortest position. By limiting the distance, the telescopic rod assembly, the rotating rod and the first awning rod form a triangular structure to keep the awning frame in the unfolded position.

[0006] US10060153 or CN109667467A adds a bottom connection seat, and a rotating rod is rotatably connected between each bottom connection seat and the first tent pole, one end of the rotating rod is rotatably connected to the bottom connection seat, and the other end is rotatably connected to the first tent pole, and a limiting rod is fixed under the top connection seat. When unfolded, the bottom connection seat passes the dead point, and the bottom connection seat abuts against the limiting rod to limit the distance between the bottom connection seat and the top connection seat. The distance is limited so that the telescopic rod assembly, the rotating rod and the first tent pole form a triangular structure to keep the tent frame in the unfolded position.
