AI Technical Summary
Portable tennis net stands are prone to loosening of the tennis net when folded for storage, lacking an effective fixing structure, making them inconvenient to take out.
The design incorporates a combination of a limiting rod, a T-shaped cylinder, and a threaded connection. By rotating the T-shaped cylinder, it moves along the threaded part of the limiting rod, causing the limiting cylinder to separate and engage at the limiting hole of the storage frame, thus enabling the tennis net to be pulled out and stored. Combined with the design of the support cylinder and the conical base, the height can be adjusted and the weight increased.
It enables the tennis net to be stably stored and unfolded within the storage frame, preventing it from becoming loose and improving the ease of use and practicality of the portable tennis net stand.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of tennis net frame technology, specifically relating to a multifunctional portable tennis net frame. Background Technology
[0002] Tennis is a ball sport. The tennis net frame is the key device that supports the net. It consists of three parts: net posts, net, and center strap. The material is usually metal (such as stainless steel or aluminum alloy) or high-strength plastic. It needs to be rust-proof and wind-resistant. Portable tennis net frames have a foldable design and are fixed with bottom weights (such as water bags or sandbags) or ground pegs, making them suitable for temporary use at home or outdoors.
[0003] In the current use of tennis net frames, portable tennis net frames are difficult to fold and store. Tennis nets have a certain length, and there is no fixed structure for storage, making them easy to fall apart and inconvenient to retrieve. Therefore, this utility model proposes a multifunctional portable tennis net frame. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional portable tennis net frame that can solve the problems mentioned in the background art.
[0005] The specific technical solution adopted in this utility model is as follows: A multifunctional portable tennis net frame includes a storage frame and a tennis net disposed between the storage frames. Two storage frames are provided, each with a winding rod rotatably connected inside. The two ends of the tennis net are fixedly connected to the two winding rods respectively. Limiting rods are installed at the top of each of the two winding rods, and threads are provided on the outer sides of each limiting rod. A T-shaped cylinder is threadedly connected to the threads, and a limiting cylinder is rotatably disposed outside the T-shaped cylinder. First limiting blocks are symmetrically installed on the limiting cylinders. A limiting hole adapted to the limiting cylinder is provided at the top of the storage frame, and first limiting grooves adapted to the first limiting blocks are symmetrically provided on the limiting hole.
[0006] The present invention is further configured such that: the interior of the T-shaped cylinder is provided with a threaded hole adapted to the thread; the top end of the T-shaped cylinder is located at the top end of the limiting cylinder; and the bottom of the T-shaped cylinder is located inside the limiting cylinder and an annular plate is installed; connecting blocks are installed on the front and back of the two storage frames; and screws are provided on each pair of connecting blocks.
[0007] The present invention is further configured such that: the inside of the limiting cylinder is provided with an annular groove adapted to the annular plate, the annular plate is rotatably disposed inside the limiting cylinder, and a second limiting block is symmetrically installed on the limiting rod below the thread.
[0008] The present invention is further configured such that: the bottom of the inner side of the limiting cylinder is symmetrically provided with a second limiting groove adapted to the second limiting block; a baffle is installed near both ends of the winding rod; and the tennis net is wound on the outside of the winding rod between the two baffles.
[0009] The present invention is further configured such that: a screw is installed at the bottom of each of the two storage boxes, a support cylinder is threadedly connected to each of the two screws, an insert rod is installed at the bottom of each of the two support cylinders, and a conical base is provided at the bottom of each of the two support cylinders.
[0010] The present invention is further configured such that: each of the two conical bases has an insertion hole at the middle position of its top end that is compatible with the insertion rod; each of the two conical bases has a connecting strap installed on one side; each of the two conical bases has a rubber plug installed on one side of its top end; the interior of the two conical bases is a cavity; and the top end of the conical bases has a through-hole, with the rubber plug embedded in the through-hole.
[0011] The technical effects achieved by this utility model are as follows: This utility model discloses a multifunctional portable tennis net holder. Through the design of a limiting rod, a T-shaped cylinder, and a threaded connection, the T-shaped cylinder moves at the threaded point on the limiting rod. The T-shaped cylinder rotates inside the limiting cylinder, and when it moves outside the limiting rod, it moves the limiting cylinder along with it, separating it from the limiting hole at the top of the storage frame. At this point, rotating the limiting rod allows the tennis net to be pulled out of the storage frame for use. When not in use, rotating the limiting rod in the opposite direction retracts the tennis net back into the storage frame and winds it onto a winding rod. The position of the limiting cylinder aligns with the limiting hole and the first limiting groove. Rotating the T-shaped cylinder causes it to engage with the limiting hole at the top of the storage frame, restricting the limiting rod and preventing the winding rod from rotating. The tennis net is then stored within the storage frame. This design allows for convenient storage of the tennis net inside the frame, making it easy to pull out when needed. The tennis net remains securely in place when stored in the frame, and the structure is simple and easy to operate. Attached Figure Description

[0014] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0015] like Figure 1-3 As shown, a multifunctional portable tennis net frame includes a storage frame 1 and a tennis net 2 disposed between the storage frames 1. There are two storage frames 1. A screw 3 is installed at the bottom of each storage frame 1. A support cylinder 4 is threaded onto each screw 3. An insertion rod 22 is installed at the bottom of each support cylinder 4. A conical base 5 is provided at the bottom of each support cylinder 4. An insertion hole 23, matching the insertion rod 22, is provided at the center of the top of each conical base 5. A connecting strap 6 is installed on one side of each conical base 5. A rubber stopper 7 is installed on one side of the top of each conical base 5. The interior of the chassis 5 is hollow, and the top of the conical chassis 5 is provided with an opening. The rubber plug 7 is embedded in the opening. The rubber plug 7 is opened at the top of the conical chassis 5 to expose the opening. Water is injected into the interior of the conical chassis 5 through the opening to increase the weight. The rubber plug 7 is then inserted into the opening to close it. The support cylinder 4 is rotated and extends and moves outside the screw 3. The tennis net 2 is placed so that its height can be adjusted. It can be used as a badminton net to improve its practicality and increase its functionality. The insertion rod 22 is inserted into the insertion hole 23 on the conical chassis 5. The storage frame 1 is placed at the top of the conical chassis 5. Both storage frames 1 are rotatably connected to a winding rod 10. The two ends of the tennis net 2 are fixedly connected to the two winding rods 10 respectively. A limit rod 12 is installed at the top of each of the two winding rods 10. Threads 13 are provided on the outer sides of each limit rod 12, and a T-shaped cylinder 14 is threadedly connected to the thread 13. A limit cylinder 15 is rotatably installed outside the T-shaped cylinder 14. First limit blocks 17 are symmetrically installed on the limit cylinder 15. A limit hole 20 adapted to the limit cylinder 15 is provided at the top of the storage frame 1. First limit grooves 21 adapted to the first limit blocks 17 are symmetrically provided on the limit hole 20. A threaded hole adapted to the thread 13 is provided inside the T-shaped cylinder 14. The top of the T-shaped cylinder 14 is located at the top of the limit cylinder 15, and the bottom of the T-shaped cylinder 14 is located inside the limit cylinder 15. Equipped with an annular plate 16, (when the tennis net 2 is placed inside the storage frame 1) rotating the T-shaped cylinder 14 causes the T-shaped cylinder 14 to move upward at the thread 13 on the limiting rod 12, driving the limiting cylinder 15 to move upward together. The limiting cylinder 15 separates from the limiting hole 20 at the top of the storage frame 1. Rotating the limiting rod 12 pulls the tennis net 2 out of the storage frame 1. Alternatively, the storage frame 1 can be pulled to the sides to pull the tennis net 2 out of the storage frame 1 for use. Then, rotating the T-shaped cylinder 14 in the opposite direction causes the T-shaped cylinder 14 to move downward at the thread 13 on the limiting rod 12, and the limiting cylinder 15 moves downward together. The first limiting block 17 and the second limiting groove 19 on the limiting cylinder 15 are respectively locked with the first limiting groove 21 and the second limiting block 18, restricting the limiting rod 12 from rotating. Connecting blocks 8 are installed on the front and back of both storage boxes 1. Screws 9 are provided on every two connecting blocks 8. (After the tennis net 2 is used and retracted into the storage box 1,) The two storage boxes 1 are aligned so that the screws 9 correspond to the connecting blocks 8 on the storage box 1. Rotating the screws 9 causes them to be located inside the two connecting blocks 8, so that the two storage boxes 1 are placed close together and retracted for easy retrieval. The inside of the limiting cylinder 15 is provided with an annular groove that matches the annular plate 16. The annular plate 16 is rotatably set inside the limiting cylinder 15. The limiting rod 12 is symmetrically equipped with second limiting blocks 18 below the thread 13. The bottom of the inside of the limiting cylinder 15 is symmetrically equipped with second limiting grooves 19 that match the second limiting blocks 18. The winding rod 10 is equipped with baffles 11 near both ends. The tennis net 2 is wound around the outside of the winding rod 10 between the two baffles 11.
[0016] The working principle of this utility model is as follows: (The overall device is in the state before use as shown in the figure) Figure 3(As shown) Open the rubber plug 7 at the top of the conical base 5 to expose the opening. Inject water into the interior of the conical base 5 through the opening to increase the weight. Then insert the rubber plug 7 into the opening to close it. Rotate the T-shaped cylinder 14. The T-shaped cylinder 14 moves upward at the thread 13 on the limiting rod 12, which drives the limiting cylinder 15 to move upward together. The limiting cylinder 15 separates from the limiting hole 20 at the top of the storage frame 1. Rotate the limiting rod 12 to pull the tennis net 2 out of the storage frame 1. Alternatively, the storage frame 1 can be pulled to both sides to pull out the tennis net 2 from inside the storage frame 1 for use. Then, the T-shaped cylinder 14 can be rotated in the opposite direction. The T-shaped cylinder 14 moves downward on the thread 13 of the limiting rod 12, and the limiting cylinder 15 moves downward together. The first limiting block 17 and the second limiting groove 19 on the limiting cylinder 15 are respectively locked with the first limiting groove 21 and the second limiting block 18, which restricts the limiting rod 12 from rotating. The support cylinder 4 extends and moves outside the screw 3 to place the tennis net 2 so that the height can be adjusted. Furthermore, the insertion rod 22 is inserted into the insertion hole 23 on the conical base 5, and the storage frame 1 is placed on the top of the conical base 5. When the whole assembly is not in use, the T-shaped cylinder 14 is rotated, and the T-shaped cylinder 14 moves upward at the thread 13 on the limiting rod 12, which drives the limiting cylinder 15 to move upward together. The limiting cylinder 15 separates from the limiting hole 20 at the top of the storage frame 1. The limiting rod 12 is rotated in the opposite direction to wind the tennis net 2 onto the winding rod 10. After winding, the limiting rod 12 is restricted, so that the screw 9 corresponds to the connecting block 8 on the storage frame 1. The screw 9 is rotated, and the screw 9 is located in the two connecting blocks 8, so that the two storage frames 1 are placed close together and put away.
[0017] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
