DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The embodiment of the present application discloses a portable tennis net device.

[0027] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A portable tennis net device includes a tennis net body 1, a lifting component 2, a limiting component 3, a fixing component 4 and a base 5.

[0028] There are two bases 5 , and a universal wheel 51 is fixedly mounted on the bottom end of the base 5 to facilitate tennis players to move the base 5 . An internal thread groove is provided on the top end of the base 5 .

[0029] Two lifting assemblies 2 are provided, each vertically mounted on a base 5. The lifting assemblies 2 include a fixed tube 21 and a lifting tube 22. The bottom end of the outer wall of the fixed tube 21 is provided with external threads, and the bottom end of the fixed tube 21 is threadedly connected to the base 5 via an internal thread groove. The fixed tube 21 and the lifting tube 22 are connected by bolts 8 and nuts 9. Opposite communication holes 211 are formed on the outer walls of the fixed tube 21 and the lifting tube 22. The bolts 8 pass through the communication holes 211 of the fixed tube 21 and the communication holes 211 of the lifting tube 22, respectively, and are threadedly connected to the nuts 9.

[0030] The bottom end of the lift tube 22 is a closed structure, with a receiving groove 223 and a circular groove 224 formed therein. The circular groove 224 is formed at the bottom of the receiving groove 223 and has a larger diameter than the receiving groove 223. A vertical T-slot 225 is formed at the top of the inner wall of the lift tube 22. A vertical oblong hole 222 is formed on the outer wall of the lift tube 22; the oblong hole 222 is not connected to the T-slot 225.

[0031] A reeling rod 221 is rotatably mounted within the lifting tube 22. A horizontal plate 2211 is fixedly mounted to the top of the reeling rod 221. A circular plate 2212 is fixedly mounted to the bottom of the reeling rod 221. The diameter of the circular plate 2212 is larger than the diameter of the receiving slot 223 and is positioned within the circular slot 224. The outer wall of the reeling rod 221 abuts against the wall of the receiving slot 223.

[0032] A first adhesive strip is fixedly mounted on the outer wall of the reel rod 221, and a second adhesive strip is fixedly mounted on each end of the net body 1. One end of the net body 1 corresponds to a reel rod 221. One end of the net body 1 passes through the oblong hole 222 and is adhesively connected to the reel rod 221, thereby adhesively connecting the second adhesive strip to the first adhesive strip. A screw block 6 is fixedly mounted on the top of the horizontal plate 2211. The screw block 6 facilitates the player's rotation of the reel rod 221, thereby tightening or loosening the net body 1. A fixing slot 61 is defined at the top of the screw block 6.

[0033] The limiting assembly 3 includes a limiting rod 31, a first limiting plate 32, and a second limiting plate 33, both of which are hollowed out. The first limiting plate 32 and the second limiting plate 33 are both located inside the lifting tube 22, and the first limiting plate 32, the second limiting plate 33, and the horizontal plate 2211 are located on the same horizontal plane. The second limiting plate 33 is located inside the first limiting plate 32, and the outer wall of the first limiting plate 32 is fixedly connected to the inner wall of the lifting tube. One end of the limiting rod 31 is fixedly connected to the inner wall of the first limiting plate 32, and the other end is fixedly connected to the outer wall of the second limiting plate 33. An annular groove 331 is defined on the inner wall of the second limiting plate 33, and the edge of the horizontal plate 2211 is located within the annular groove 331. A roller 7 is rotatably mounted within the annular groove 331. The outer wall of the roller 7 abuts against the groove wall of the annular groove 331 and the outer wall of the horizontal plate 2211, respectively. The roller 7 reduces friction between the horizontal plate 2211 and the second stop plate 33, thereby increasing the service life of the horizontal plate 2211 and the second stop plate 33. The stop assembly 3 prevents the winding rod 221 from sliding off the lifting tube 22.

[0034] A T-slot 225 is defined on the inner wall of the lifting tube 22, located above the screw block 6. The fixing assembly 4 includes a T-block 41 and a fixing block 42. The T-block 41 is slidably connected to the lifting tube 22 via the T-slot 225. The fixing block 42 is horizontally fixedly connected to the T-slot 225 and inserted into the fixing slot 61. It is understood that both the fixing block 42 and the fixing slot 61 have the same irregular shape. When a tennis player is playing tennis, the tennis ball is struck by the tennis ball. The configuration of the fixing assembly 4 prevents the reeling rod 221 from rotating, thereby changing the length of the tennis ball.

[0035] An auxiliary rope 226 is fixedly installed on the outer wall of the lifting tube 22, one end of the auxiliary rope 226 is fixedly connected to the lifting tube 22, and the other end is fixedly connected to the T-block 41. When screwing the screwing block 6, it is necessary to slide the T-block 41 out of the T-slot 225, which is convenient for tennis players to screw.

[0036] The implementation principle of a portable tennis net device according to an embodiment of the present application is as follows: a tennis player moves the base 5, installs the lifting assembly 2 on the base 5, slides the lifting tube 22 out of the fixing tube 21, and fixes it with bolts 8 and nuts 9. Then, the base 5 is rotated so that the oblong holes 222 on the two lifting tubes 22 face each other. The opposite ends of the tennis ball body are placed inside the lifting tubes 22 through the oblong holes 222 of the two lifting tubes 22, and the first adhesive strip and the second adhesive strip are glued together. It can be seen that the width of the oblong holes 222 is sufficient to allow the tennis player's fingers to enter the lifting tubes 22. Subsequently, the screw block 6 is rotated to rotate the winding rod 221, thereby driving the tennis ball body to tighten. Finally, the T-block 41 is slid into the T-slot 225, so that the fixing block 42 and the fixing slot 61 are inserted and engaged. At this point, the tennis player can play tennis. After the tennis player finishes playing tennis, he or she uses the auxiliary rope 226 to remove the T-block 41 from the T-slot 225, and then reversely rotates the rotating block 6 to relax the tennis ball body. Then, the first adhesive strip and the second adhesive strip are separated, and the bolt 8 and the nut 9 are separated to slide the lifting tube 22 into the fixing tube 21. The device of the present application is easy to carry.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
