Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Example: Figure 7 , Figure 8 As shown:

[0042] The connecting rod 8 is made of glass fiber rod and can be elastically bent within a certain range; the eaves cantilever rod 10 is also made of glass fiber rod. The telescopic rod assembly 9 can adjust its length and is an existing structure and will not be described in detail.

[0043] The first four-way umbrella head assembly 5 and the second four-way umbrella head assembly 6 have the same structure and can be used interchangeably.

[0044] The first four-way umbrella head assembly 5 is located at the central node position of the field-shaped outline, the four second four-way umbrella head assemblies 6 are respectively located at the middle node positions of the upper middle, lower middle, left middle and right middle sides, and the four three-way umbrella head assemblies 7 are respectively located at the four corner node positions of the upper left, lower left, upper right and lower right.

[0045] The first, second, third and fourth umbrella heads of the first four-way umbrella head assembly 5 are respectively connected to the first umbrella head of the second four-way umbrella head assembly 6 at the middle nodes of the four sidelines through the connecting frame rod 8;

[0046] The first and second umbrella heads in the three-way umbrella head group 7 are respectively connected to the second / third umbrella heads of two adjacent second four-way umbrella head assemblies 6 through a connecting rod 8; the third umbrella head in the three-way umbrella head group 7 is connected to the end of the telescopic rod assembly 9;

[0047] The first, second and third umbrella heads of the second four-way umbrella head assembly 6 are connected to corresponding connecting rods 8, and the connecting rods 8 are used to connect with the first four-way umbrella head assembly 5 / three-way umbrella head assembly 7; the fourth umbrella head of the second four-way umbrella head assembly 6 is connected to the eaves cantilever rod 10.

[0048] like Fig. 9 As shown, the telescopic rod assembly 9 and the two connecting frame rods 8 are all rotatably connected to the three-way umbrella head assembly 7.

[0049] The second four-way umbrella head assembly 6 is as follows Figure 1-Figure 6As shown, it includes a base 1, a first connecting member 2 and a second connecting member 3;

[0050] A through hole 12 is provided in the middle of the base 1, which is narrow in the middle and wide at both ends. Four card slots 11 are arranged around the through hole 12 on the top of the base 1. Figure 2 The four slots 11 are arranged in a cross shape; two adjacent side openings are arranged on the six sides of the slot 11, namely the top surface of the slot 11 and a side away from the through hole 12; a rotating shaft is arranged in each slot 11 (not shown in the drawings).

[0051] The ends of the first connecting member 2 and the second connecting member 3 are both adapted to the slot 11. The first connecting member 2 and the second connecting member 3 are provided with a socket 31 of the same shape at one end away from the base 1. The connecting rod 8 and the eaves cantilever rod 10 can be inserted into the socket 31 and fixed with the clamping screws.

[0052] One end of the first connecting member 2 is rotatably connected to the corresponding slot 11 via a rotating shaft, and the first connecting member 2 rotates within the corresponding slot 11 within a range of 0°-90°. Figure 6 As shown, a waist-shaped hole 33 is opened at one end of the second connecting member 3, and the width of the waist-shaped hole 33 is adapted to the outer diameter of the rotating shaft. The rotating shaft rotates and moves relatively in the waist-shaped hole 33, so that the second connecting member 3 can rotate and move relative to the slot 11 through the cooperation of the waist-shaped hole 33 and the rotating shaft.

[0053] like Figure 2 , Figure 3 As shown, the first limiting portion includes a first limiting groove 13 and a second limiting groove 14. The first limiting groove 13 is opened on a side wall of the slot 11 close to the through hole 12, and the second limiting groove 14 is opened on a side edge position of the slot 11 away from the through hole 12; the bottom wall of the slot 11 is also opened with an avoidance groove 111, and the avoidance groove 111 is used to provide a movable space for the first limiting boss 32 during the rotation of the second connecting member 3.

[0054] like Figure 6 As shown, the second limiting portion includes a first limiting boss 32 and a second limiting boss 34. The first limiting boss 32 is arranged on the left side wall of the second connecting member 3, and the second limiting boss 34 is arranged on the front and rear side walls of the second connecting member 3; and the first limiting boss 32 is located on the left side of the waist-shaped hole 33, and the second limiting boss 34 is located on the right side of the waist-shaped hole 33; to avoid insufficient strength when the first limiting portion and the second limiting portion for plug-in mating are arranged on one side of the rotating shaft.

[0055] like Figure 4As shown, the lower end of the fastener 4 is provided with a thread hole 41 that passes through the left and right sides, the outer diameter of the lower end of the fastener 4 is larger than the inner diameter of the through hole 12, and the upper end of the fastener 4 is provided with a cross groove 42 of a cross-shaped structure, so that four isolated islands are formed on the upper end of the fastener 4, so that it has a certain deformation ability; when in use, the belt of the tent fabric passes through the thread hole 41 and is knotted to achieve the connection between the fastener 4 and the tent fabric; then as shown in FIG. Figure 1 As shown, the other end of the fastener 4 is inserted into the through hole 12, and a self-tapping screw is used to spirally insert it into the cross groove 42 of the fastener 4, so that the self-tapping screw cooperates with the inner thread of the cross groove 42 of the fastener 4 and pushes the four isolated parts to expand outward, thereby fixing the fastener 4 in the through hole 12, and the self-tapping screw and the end of the fastener 4 with the wire hole 41 are respectively located on opposite sides of the base 1.

[0056] The rotating shaft includes a T-shaped threaded rod and a nut fastener. One end of the threaded rod and the nut fastener are detachably threadedly connected to each other, so that the first connecting member 2 and the second connecting member 3 can be removed from the slot 11 or replaced with a new one at a later time.

[0057] Working principle:

[0058] The two first connecting members 2 and one second connecting member 3 are used to install the corresponding connecting rods 8, and the remaining second connecting member 3 is used to install the eaves cantilever rod 10.

[0059] The free end of the eaves cantilever rod 10 is connected to the tent fabric, so that the eaves cantilever rod 10 can be used as an extended eave of the tent when unfolded. The eaves cantilever rod 10 in the unfolded state cooperates with the tent fabric to expand the sunshade area.

[0060] The second connecting member 3 of the eaves cantilever rod 10 is rotated so that the length of the second connecting member 3 is relatively parallel to the upper surface of the base 1, and the tent is unfolded. The tent fabric is in a stretched and tensioned state. The tension of the tent fabric drives the second connecting member 3 to extend into the slot 11. Figure 1 As shown, at this time, the first limiting boss 32 of the second connecting member 3 is inserted into the first limiting groove 13, and at the same time, the second limiting boss 34 of the second connecting member 3 is inserted into the second limiting groove 14, so that the second connecting member 3 cannot rotate relative to the base 1.

[0061] When disassembly is required, external force is applied to manually drive the second connecting member 3 out of the slot 11, so that the first limiting boss 32 is disengaged from the first limiting groove 13, and the second limiting boss 34 is disengaged from the second limiting groove 14. Then the second connecting member 3 can be rotated relative to the base 1, and the second connecting member 3 is rotated to be perpendicular to the base 1 to reduce its size.

[0062] During normal use of the tent, if there is no need to extend the eaves to expand the sunshade area, the second connecting member 3 can be rotated so that its first limiting boss 32 is inserted into the avoidance groove 111 to fold up the extended eaves.
