[0023] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0024] like Figure 1-6 As shown, an easily assembled goal frame includes a crossbeam 1, a bottom beam 2, a flexible rear beam 3, two uprights 4, two corner joints 5, two support rod assemblies 6, and two base rods 7. The uprights 4 are detachably connected to the crossbeam 1 via the corner joints 5. The two ends of the bottom beam 2 are detachably connected to the two base rods 7 respectively. The two ends of the flexible rear beam 3 are detachably connected to the corners of the two support rod assemblies 6 respectively. The two ends of the base rods 7 are detachably connected to the bottom of the uprights 4 and one end of the support rod assembly 6 respectively. The other end of the support rod assembly 6 is detachably connected to the corner of the corner joint 5.

[0025] This easily assembled goal frame features a detachable connection between the uprights 4 and the crossbeam 1 via corner joints 5. The bottom beam 2 is detachably connected at both ends to two bottom poles 7. The flexible rear beam 3 is detachably connected at both ends to the corners of two support rod assemblies 6. The bottom poles 7 are detachably connected at both ends to the bottom of the uprights 4 and one end of the support rod assembly 6, respectively. The other end of the support rod assembly 6 is detachably connected to the corner of the corner joint 5. This design avoids welding for fixing the crossbeam 1, bottom beam 2, flexible rear beam 3, two uprights 4, two corner joints 5, two support rod assemblies 6, and two bottom poles 7, making assembly and disassembly easier, facilitating transport and outdoor use, and simplifying disassembly and relocation. Furthermore, the flexible rear beam 3, connected at the corners of the two support rod assemblies 6, directly supports the rear half of the net, preventing it from sagging. This eliminates the need for the traditional method of using two uprights and ropes to suspend the net from the back. The lighter weight of the flexible rear beam 3 also contributes to reducing the overall weight of the goal frame.

[0026] Furthermore, the corner joint 5 includes a hollow corner tube 51 for the door frame and a corner reinforcing tube 52 nested within the hollow corner tube 51 and extending to both ends of the hollow corner tube 51. The inner wall of the hollow corner tube 51 has multiple spaced-apart limiting ridges 8, all of which abut against the outer wall of the corner reinforcing tube 52. The two ends of the corner reinforcing tube 52 are respectively inserted into the crossbeam 1 and the column 4. The multiple limiting ridges 8 and the corner reinforcing tube 52 work together to enhance the overall structural strength and load-bearing capacity of the double-tube reinforced structure, resulting in greater structural stability and preventing the corner joint 5 from easily deforming during human climbing after the goal is assembled.

[0027] Furthermore, the hollow tube 51 at the corner of the door frame is an aluminum alloy hollow tube, and the corner reinforcing tube 52 is a hollow iron tube, which together enhance the overall structural strength and load-bearing capacity of the corner joint 5.

[0028] Furthermore, the crossbeam 1, corner joint 5, and upright 4 are respectively provided with recessed transverse guide rails 9, right-angle guide rails 10, and longitudinal guide rails 11. Multiple I-shaped rope buckles 12 for fastening the net are slidably connected to the transverse guide rails 9, right-angle guide rails 10, and longitudinal guide rails 11. The sliding contact surface of each I-shaped rope buckle 12 has a protruding damping strip 13 to provide sliding resistance. Multiple I-shaped rope buckles 12 are slidably connected to the transverse guide rails 9, right-angle guide rails 10, and longitudinal guide rails 11, so that the net can be hung on the crossbeam 1, corner joint 5, and upright 4 via the I-shaped rope buckles 12. In addition, the damping strip 13 helps to prevent the I-shaped rope buckles 12 from easily sliding and affecting the normal use of the net.

[0029] Furthermore, the bottom beam 2 and the two bottom rods 7 are each fixedly connected with multiple spaced net clips 14 for fastening the net. The net clips 14 fix the bottom of the net to the bottom beam 2 and the two bottom rods 7, preventing balls from leaking out between the net and the bottom beam 2, and between the net and the two bottom rods 7 during use.

[0030] Furthermore, each of the two support rod groups 6 is fixedly connected with a hanging ring 15 at its corner. The flexible rear beam 3 includes a flexible rope 31 and two locking buckles 32. The end of the flexible rope 31 is connected to the hanging ring 15 through the locking buckle 32, so that the flexible rope 31 is arranged laterally between the two support rod groups 6 to form a flexible rear beam 3. When applied to the goal and the net is hung, the flexible rope 31 directly supports the rear half of the net, avoiding the problem of the rear half of the net collapsing. It is easy to assemble and helps to avoid the cost of adding two additional uprights, which helps to reduce the overall weight of the goal frame.

[0031] Furthermore, the end of the flexible rope 31 is bent and pressed together by the rope clamp 16 to form a loop structure 17. The loop structure 17 is fastened to the lock 32. The loop structure 17 can be used directly, avoiding manual knotting during assembly and improving assembly efficiency.

[0032] Furthermore, the support rod assembly 6 includes a first upright rod 61, a second upright rod 62, and a corner support rod 63 that are sequentially inserted and connected. The hanging ring 15 is fixedly connected to the corner of the corner support rod 63. During assembly, the first upright rod 61, the second upright rod 62, and the corner support rod 63 are sequentially inserted and connected, which helps to improve assembly efficiency.

[0033] Furthermore, the goal frame also includes a sheet metal part 18 fixedly connected to the end of the corner support rod 63 away from the second upright rod 62. The corner support rod 63 is detachably connected to the corner joint 5 through the sheet metal part 18, which facilitates assembly and disassembly, makes it easy to transport and carry outdoors, and facilitates disassembly and relocation. Even further, the sheet metal part 18 is fixedly fastened to the corner joint 5 with bolts.

[0034] Furthermore, the bottom of the column 4 is provided with an insertion hole 19, one end of the bottom rod 7 is inserted into the insertion hole 19, and the other end of the bottom rod 7 has a connecting pipe 20 protruding from it. The bottom end of the support rod group 6 is inserted into the connecting pipe 20.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
