[0037] Specifically, by Figure 1-Figure 4 A mobile tennis post is provided, comprising: a storage component, the storage component comprising two posts 1, a net 5 is arranged between the two posts 1; a moving component, arranged on the bottom surfaces of the two posts 1, and used to move the storage component; a storage cavity 101 is opened in the post 1, a fixed post 102 is arranged at the center of the bottom surface of the storage cavity 101, a roller 3 is arranged on the fixed post 102 so as to be rotatable laterally, one end of the net 5 is fixedly connected to the side wall of the roller 3, a first locking block 6 is fixedly connected to the top surface of the roller 3, a guide post 7 is arranged above the first locking block 6, one end of the guide post 7 is fixedly connected to the second locking block 701, the first locking block 6 is engaged with the second locking block 701, a rectangular through hole 103 is opened at the center of the top surface of the post 1, and the other end of the guide post 7 passes through the rectangular through hole 103 and is arranged on the top surface of the post 1.

[0038] In the utility model, by adopting the above-mentioned design, when setting up the tennis pole, the trainer can pull the guide column 7 to make the second locking block 701 move away from the first locking block 6, and then adjust the positions of the two columns 1 by moving the assembly. After the column 1 reaches the specified position, the guide column 7 is lowered to fix the position of the roller 3, thereby fixing the length of the net 5, and then the setting can be completed.

[0039] This makes the distance between the two columns 1 not fixed and can be adjusted according to the position and direction of the venue, making the device applicable to a wider range of venues, and the positions and angles of the two columns 1 can be freely adjusted, making the training methods of the trainees more diverse and flexible, and when disassembling and moving, only the two columns 1 need to be moved, making the moving and disassembly process simple and fast, reducing the use cost and time cost.

[0040] Furthermore, as a specific implementation of the utility model, the utility model provides a movable tennis post.

[0041] Specifically, Figure 1As shown, the moving component includes a moving disk 2, which is arranged on the bottom surface of the column 1. The moving disk 2 is triangular in shape. A locking universal wheel 201 and two universal wheels 202 are arranged at the triangular portion of the bottom surface of the moving disk 2. One corner of the locking universal wheel 201 is facing the left or right side of the column 1, and the sharp corners of the moving disk 2 are all rounded.

[0042] In the utility model, by adopting the above-mentioned design, the trainee can drag the column 1 by locking the universal wheel 201 and the universal wheel 202 on one side of the column 1, and use rolling friction instead of sliding friction, so that the trainee can save more effort when moving the column 1, and the trainee can fix the position of the column 1 by stepping on the universal wheel 202 after dragging. The rounded corners can prevent the trainee from being injured due to collision with the sharp corners of the moving disk 2 when moving the column 1.

[0043] Furthermore, as a specific implementation of the utility model, the utility model provides a movable tennis post.

[0044] Specifically, Figure 3 and Figure 4 As shown, one end of a torsion spring 4 is fixedly connected to the bottom surface of the storage cavity 101, and the torsion spring 4 is sleeved around the outer wall of the fixed column 102. A circular ring is integrally formed on the bottom surface of the drum 3, and the other end of the torsion spring 4 is fixedly connected to the bottom surface of the circular ring.

[0045] In the utility model, by adopting the above-mentioned design, when setting up the tennis pole, the torsion spring 4 will deform and accumulate elastic potential energy. When the tennis pole needs to be stored, it is only necessary to pull up the guide column 7 to drive the second locking block 701 away from the first locking block 6. The torsion spring 4 will convert the elastic potential energy previously accumulated into kinetic energy, and automatically drive the roller 3 to reset and thus complete the winding of the net 5.

[0046] Furthermore, as a specific implementation of the utility model, the utility model provides a movable tennis post.

[0047] Specifically, Figure 3 and Figure 4 As shown, one end of a spring 8 is fixedly connected to the top surface of the second locking block 701 . The spring 8 is sleeved around the outer wall of the guide column 7 . The other end of the spring 8 is fixedly connected to the top surface of the storage cavity 101 .

[0048] In the utility model, by adopting the above-mentioned design, the second locking block 701 will always conflict with the first locking block 6 without human interference, preventing the second locking block 701 from falling off from the first locking block 6 due to unexpected factors during transportation or training, thereby causing the net 5 to become loose.

[0049] Furthermore, as a specific implementation of the utility model, the utility model provides a movable tennis post.

[0050] Specifically, Figure 3 and Figure 4 As shown, a plurality of clamping blocks are arranged on the first locking block 6, and the plurality of clamping blocks are arranged in a circular array at equal intervals, and each clamping block is provided with a chamfer 601, and the chamfers 601 are oriented in the same direction.

[0051] In the utility model, by adopting the above-mentioned design, when setting up the tennis pole, under the pull of the trainer, the chamfer 601 provided on the first locking block 6 will automatically push the second locking block 701 upward, so that the second locking block 701 can only rotate in one direction, thereby making it possible to set up the tennis pole without pulling the guide column 7, making the setting up of the tennis pole more convenient.

[0052] Furthermore, as a specific implementation of the utility model, the utility model provides a movable tennis post.

[0053] Specifically, Figure 1-Figure 4 As shown, a handle 9 is provided on the top surface of the guide column 7 , guard plates are provided on both sides of the handle 9 , and a rubber sleeve 901 is provided on the handle 9 .

[0054] In the present invention, by adopting the above-mentioned design, when the trainee stores the tennis pole, he can pull the guide pole 7 by holding the handle 9, which makes it more convenient for the trainee to store the tennis pole. In addition, the rubber sleeve 901 arranged on the handle 9 has a relatively soft texture and a higher friction force due to the characteristics of the material itself, which further facilitates the trainee to apply force when holding the handle 9.

[0055] Working principle:

[0056] In order to adapt to more venues, enrich the training methods and flexibility of trainers, and simplify the movement and disassembly of tennis poles.

[0057] In the utility model, a storage component and a moving component are provided.

[0058] When setting up the tennis pole, the column 1 can be transported to a designated position through the moving assembly, and the locking universal wheel 201 on one side of the column 1 can be stepped on to fix one column 1, and then the other column 1 can be transported to another designated position through the moving assembly to complete the setting up of the tennis pole. When it needs to be disassembled or moved, it is only necessary to hold and pull the handle 9 to drive the second locking block 701 away from the first locking block 6 to automatically complete the storage.

[0059] The distance between the two uprights 1 is not fixed, and can be adjusted according to the position and direction of the venue, so that the device can be applied to a wider range of venues, and the positions and angles of the two uprights 1 can be freely adjusted, making the training methods of the trainees more diverse and flexible. When disassembling, only the handle 9 needs to be pulled to automatically complete the storage of the net 5, and the disassembly process becomes simple and fast, reducing the use cost and time cost.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
