[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] As Figure 4 shown, a four-corner tent bracket provided by the embodiment includes a connecting piece 4 and four vertical first telescopic rods 1. The top of the first telescopic rod 1 is hinged to the second telescopic rod 3, and one end of the second telescopic rod 3 away from the first telescopic rod 1 is hinged to the connecting piece 4. Adjacent first telescopic rods 1 are connected by an X-shaped telescopic bracket 2. The above is the basic structure of the tent bracket in the prior art;

[0032] The invention point of this application lies in:

[0033] As Figures 1 to 3 shown, the bottom plate of the square tube 13 is not shown. The first telescopic rod 1 includes a first fixed tube 11 and a first sliding rod 12 slidably disposed within the first fixed tube 11;

[0034] The top end of the first sliding rod 12 passes through the first fixed tube 11, and a vertical rack 121 is provided at the bottom of the first sliding rod 12. The X-shaped telescopic bracket 2 is disposed on the upper part of the first sliding rod 12;

[0035] A coaxial and communicating square tube 13 is provided at the bottom end of the first fixed tube 11. A rotatable half gear 15 is disposed within the square tube 13. A vertically extending strip-shaped hole 132 is provided on the side wall of the square tube 13. A foot plate 14 is fixedly disposed along the tangent direction on the toothless part of the outer edge of the half gear 15. The rotation of the half gear 15 can drive the foot plate 14 to rotate out from the strip-shaped hole 132, and a through hole 141 is provided on the foot plate 14;

[0036] When the rack 121 is located in the lower part of the square tube 13, it meshes with the half gear 15.

[0037] Specifically, a shaft rod 16 is arranged coaxially with the half gear 15. The half gear 15 is rotatably connected to the shaft rod 16 through a bearing 151, and the inner ring of the bearing 151 is fixedly connected to the shaft rod 16;

[0038] One end of the shaft rod 16 is provided with a threaded section 161, and a threaded hole 131 is arranged on the side wall of the square tube 13 to cooperate with the threaded section 161.

[0039] A horizontal guide tube 162 is arranged on the inner side wall of the square tube 13, and the other end of the shaft rod 16 is slidably arranged in the guide tube 162.

[0040] A backing plate 142 is arranged on the side of the foot plate 14 away from the center of the half gear 15. The width and length of the backing plate 142 are the same as those of the foot plate 14. There are two through holes 141 that penetrate the backing plate 142, and the width of the strip-shaped hole 132 is greater than the widths of the foot plate 14 and the backing plate 142.

[0041] Magnetic sheets 5 that can be magnetically attracted to the backing plate 142 are arranged on the vertical side walls of the strip-shaped hole 132.

[0042] With the backing plate 142 located in the strip-shaped hole 132, during use, first expand the four first telescopic rods 1 as in the prior art, and then lift the first sliding rod 12, which drives the rack 121 to rise, thereby driving the half gear 15 to rotate 90 degrees, causing the foot plate 14 to rotate to the outside of the strip-shaped hole 132, that is, from the Figure 6 state to the Figure 7 state. After that, the backing plate 142 touches the ground, and a U-shaped pin rod can be inserted into the two through holes 141 to complete the fixation of the first telescopic rod 1 to the ground. Then, lift the connecting piece 4 to support the tent top. When putting away the tent, as the first sliding rod 12 drives the rack 121 downward, the half gear 15 can be rotated in the reverse direction to retract the foot plate 14 into the strip-shaped hole 132.

[0043] When the site is limited and it is not desired to expand the foot plate 14, the shaft rod 16 can be rotated, and the end of the shaft rod 16 without the threaded section 161 can be pushed into the guide tube 162, so that the half gear 15 is disengaged from the rack 121, and after moving, the backing plate 142 is magnetically attracted to the magnetic sheet 5, keeping the foot plate 14 still in a vertical state.

[0044] Furthermore, as shown in Figure 5 , a fixing hole 7 is arranged on the first fixing tube 11, and a plug rod 6 that can pop out horizontally is arranged on the first sliding rod 12 to fix the extended first telescopic rod 1, that is, after extension, the fixing hole 7 is aligned with the plug rod 6, and the plug rod 6 is ejected by a spring. When it is necessary to retract the first sliding rod 12, press the plug rod 6 inward. Using a snap structure as the fixing part of the telescopic rod is a conventional technical solution in the art.

[0045] Similarly, the second telescopic rod 3 can also adopt the above structure.

[0046] In addition, a pull ring 41 is provided at the bottom of the connecting member 4, which facilitates the operation when the tent bracket is retracted.

[0047] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
