[0002] The sports net is a sports facility and also a sports equipment. Its main body is made of high-quality dark natural or artificial fibers. Support structures are installed on the left and right ends of its bottom. When assembling the existing sports net, it is necessary to manually place the support structures on both sides of the sports net on both sides of the sports field, and then hang the sports net on the support structures. Since the support structures require a heavier weight to support the sports net and keep the sports net in an unfolded state, and manual labor needs to consume more physical strength in the process of carrying the support structures, the existing sports net is inconvenient to install.

[0003] After searching, the publication number CN214861053U discloses a sports net that is easy to assemble, which relates to the field of sports equipment technology, including a base, the number of which is two, and wheels are movably connected to the inner wall of the base through a pin shaft on both sides, a main cylinder is fixedly inserted into the top of the base, a positioning groove is provided on the top of the main cylinder, a lifting rod is fixedly connected to the inner wall of the positioning groove, a brake block is fixedly connected to the bottom of the lifting rod, a push cylinder is sleeved on the outer side of the main cylinder, a latch is movably inserted into the front of the push cylinder, a spring is sleeved on the outer side of the latch, and a scissor rod structure is movably connected to the front of the push cylinder through a pin shaft. When the device is in use, by standing on one side of the sports field and pulling the handle of one main cylinder upward, the scissor rod structure is extended, and the other main cylinder is pushed away from the grasped main cylinder with the cooperation of the wheels at its bottom, that is, when the handle of one main cylinder is pulled upward, the other main cylinder is pushed to move to the other side of the sports field;

[0004] The above-mentioned utility model does not require manual handling of the support structure and can unfold the sports net by operating the support structure on one side, thereby improving the convenience of assembling the sports net.

[0028] A sports net that is easy to assemble, comprising a base 1, wherein the base 1 is provided with two groups, the tops of the two groups of bases 1 are respectively fixedly connected with a first support rod 2 and a second support rod 3, a sports net body 4 is installed at the tops of the two groups of first support rods 2 and second support rods 3, a folding frame 5 is installed between the first support rod 2 and the second support rod 3, the tops of the left and right sides of the folding frame 5 are fixedly connected with the first support rod 2 and the second support rod 3 through a connecting sleeve 6, and the bottoms of the left and right sides of the folding frame 5 are slidably connected with the first support rod 2 and the second support rod 3 through a sliding sleeve 7, and further comprising:

[0029] The lifting mechanism 8 is fixedly installed on the outer side of the second support rod 3 , and is used for folding the moving net body 4 and lifting and lowering the sliding sleeve 7 .

[0030] First, the lifting mechanism 8 includes a driving box 801 fixedly connected to the bottom end of the second supporting rod 3, the outer side of the driving box 801 is rotatably connected with a crank 802, and the top of the driving box 801 is rotatably connected with a threaded rod 803, the top of the threaded rod 803 is rotatably connected to the connecting sleeve 6 through a first connecting block 804, the outer side of the threaded rod 803 is threadedly connected to the sliding sleeve 7 through a second connecting block 805, the outer side of the second connecting block 805 is fixedly connected with a lifting rod 806, and the top of the lifting rod 806 is fixedly connected to the moving net body 4 through a connecting rod 807. When assembling the moving net body 4, rotating the crank 802 drives the threaded rod 803 to rotate, and drives the sliding sleeve 7 to slide upward under the connection of the second connecting block 805, thereby driving the folding frame 5 to unfold, pushing the base 1 to move to unfold the moving net body 4 horizontally, and at the same time, the upward movement of the second connecting block 805 drives the lifting rod 806 to move upward, thereby turning the longitudinally folded moving net body 4 upward, and then fully unfolding the moving net body 4, and only one person is required to perform the assembly operation during the operation.

[0031] Furthermore, multiple sets of moving wheels 101 are installed at the bottom of the two sets of bases 1, and the ends of the bottoms of the two sets of bases 1 that are away from each other are threadedly connected with fixed legs 102. The base 1 is moved by the multiple sets of moving wheels 101 at the bottom, and when the sports net main body 4 is in use, the fixed legs 102 are rotated downward to make them press against the ground to increase friction, thereby preventing the sports net main body 4 from moving and maintaining stability.

[0032] Then, the top ends of the left and right sides of the folding frame 5 are rotatably connected to the connecting sleeve 6, and the bottom ends of the left and right sides of the folding frame 5 are rotatably connected to the sliding sleeve 7. When the lifting mechanism 8 is used to drive the sliding sleeve 7 to move upward, the folding frame 5 can be driven to unfold and push the base 1 to move to unfold the sports net body 4 horizontally.

When assembling the sports net main body 4, first pull the pull rod 812 to release the fixed tooth block 813 from fixing the fixed gear 810, and use the sliding rod 815 to ensure the stable movement of the fixed tooth block 813, and then turn the crank 802 to lift and lower the sliding sleeve 7.

[0036] Finally, the top ends of the left and right sides of the sports net main body 4 are slidably connected to the connecting rod 807 through the first connecting column 816, and the outer side of the first connecting column 816 is fixedly connected to the connecting rod 807 by screws, and the bottom ends of the left and right sides of the sports net main body 4 are slidably connected to the top ends of the first support rod 2 and the second support rod 3 through the second connecting column 817, and the outer side of the second connecting column 817 is fixedly connected to the top ends of the first support rod 2 and the second support rod 3 by screws. When the sports net main body 4 is in use, the first connecting column 816 and the second connecting column 817 are fixed by screws, so as to fix the four corners of the sports net main body 4 to ensure its stability during use. After the sports net main body 4 is damaged, the screws fixing the first connecting column 816 and the second connecting column 817 are unscrewed and then disassembled, the first connecting column 816 is pulled out from the inner side of the connecting rod 807, and the second connecting column 817 is pulled out from the top end of the second support rod 3, and the sports net main body 4 can be disassembled for replacement, which further improves the convenience of replacing the sports net main body 4.

[0037] In this embodiment, the implementation scenario is specifically as follows: when assembling the sports net main body 4, first pull the pull rod 812 so that the fixed tooth block 813 releases the fixation of the fixed gear 810, and then turn the crank 802 to drive the driving gear 808 to rotate, and drive the threaded rod 803 to rotate under the transmission of the driven gear 809, and drive the sliding sleeve 7 to slide upward under the connection of the second connecting block 805, thereby driving the folding frame 5 to unfold, and push the base 1 to move to unfold the sports net main body 4 horizontally. At the same time, the upward movement of the second connecting block 805 drives the lifting rod 806 to move upward, thereby turning the longitudinally folded sports net main body 4 upward, and then fully unfolding the sports net main body 4, and when the sports net main body 4 is used, it is turned downward to fix it. The support foot 102 makes it press against the ground to increase friction, thereby preventing the sports net main body 4 from moving and maintaining stability. After the sports net main body 4 is damaged, the screws fixing the first connecting column 816 and the second connecting column 817 are unscrewed for disassembly, and the first connecting column 816 is pulled out from the inner side of the connecting rod 807, and the second connecting column 817 is pulled out from the top of the second support rod 3. The sports net main body 4 can be disassembled for replacement. The entire operation process is simple and convenient. Compared with the existing sports nets that are easy to assemble, the utility model is designed so that not only one person can complete the assembly operation of the sports net, but also the operation is convenient and labor-saving, thereby greatly improving the convenience of assembly of the sports net. At the same time, it improves the convenience of replacing the sports net after the sports net is damaged.
