Description

Technical Field

[0001] This utility model relates to the technical field of ball training, specifically to an automatically foldable ball collection and recovery net frame. Background Technology

[0002] In training and matches of ball sports such as basketball, volleyball, and soccer, ball recovery and distribution are always crucial and time-consuming tasks. In ball sports, especially basketball and volleyball, training typically requires a large number of repeated shots, passes, and catches with the ball.

[0003] Existing ball collection and retrieval systems are typically installed in fixed locations, using electrically or mechanically driven ball-collecting devices to gather balls into a storage area. These systems are complex, bulky, and lack portability, making them difficult to move and install in different locations. Furthermore, manufacturing errors in the ball-collecting net itself and unreliable anchoring methods with the net frame result in an insufficiently tight overall net after deployment, hindering the normal descent of training balls and even causing balls to get stuck. Therefore, this invention proposes an automatically foldable ball collection and retrieval net frame. Utility Model Content

[0004] The purpose of this utility model is to provide an automatically foldable ball collection and recovery net frame to solve the problems mentioned in the background art. The existing ball collection and recovery systems are usually installed in fixed venues and collect balls to the storage area through electric or mechanically driven ball collection devices. They are complex in structure and bulky, lack portability, and are difficult to move and install in different venues. Moreover, due to manufacturing errors of the ball collection net itself and unreliable anchoring methods between it and the net frame, the ball collection net is not tight enough after deployment, which hinders the normal fall of training balls and even causes ball jamming.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

An end rod is movably connected to the other end of the long traction rod. A slider is fixedly connected to the upper end of the lead screw of the lead screw stepper motor. Several second lifting lugs are provided on the outer wall of the slider corresponding to the umbrella frame base. A sliding rod is movably connected to each of the second lifting lugs. A short traction rod is movably connected to the sliding rod. An intermediate rod is movably connected to the end of the short traction rod away from the sliding rod.

[0007] Optionally, the end of the sliding rod is movably connected to the middle of the first end rod via a pin, the end of the first end rod is movably connected to the body of the intermediate rod via a pin, and the end of the intermediate rod is movably connected to the body of the end rod via a pin.

[0008] Optionally, the bottom of the connecting mounting plate is symmetrically provided with columns, and the bottom ends of the columns on both sides are fixedly connected with support plates.

[0009] Optionally, the lead screw of the lead screw stepper motor is fitted with a sleeve, and the lead screw is slidably disposed within the sleeve.

[0011] Optionally, the ball-collecting net is divided into an upper part and a lower part, the upper part being a hollow inverted square shape, and the lower part being a hollow cylinder shape.

[0012] Optionally, the ball-collecting net is made of nylon.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model adopts a multi-stage linkage folding arm design, which realizes the controllable contraction and expansion of the ball-collecting net through the drive of a lead screw stepper motor. This design not only improves the tightness of the ball-collecting net, but also ensures the stability and reliability during the ball-collecting process.

[0015] 2.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The preferred embodiment of the present invention will be described below.

[0026] Please see Figure 1-6 As shown, the automatically foldable ball collection and recycling net frame includes a connecting mounting plate 1. A lead screw stepper motor 2 is fixedly mounted on the connecting mounting plate 1. An umbrella frame base 3 is fixedly mounted on the upper end face of the lead screw stepper motor 2. The umbrella frame base 3 is movably connected to several first end rods 8 through a first lifting lug 5 arranged around the perimeter. A long traction rod 9 is movably connected to the first end rod 8. An end rod 10 is movably connected to the other end of the long traction rod 9. A slider 6 is fixedly connected to the upper end of the lead screw of the lead screw stepper motor 2. Several second lifting lugs 7 are provided on the outer wall of the slider 6 corresponding to the umbrella frame base 3. A sliding rod 11 is movably connected to each of the several second lifting lugs 7. A short traction rod 12 is movably connected to the sliding rod 11. An intermediate rod 13 is movably connected to the end of the short traction rod 12 away from the sliding rod 11.

[0027] Furthermore, the lead screw of the lead screw stepper motor 2 is fitted with a sleeve 4, and the lead screw is slidably disposed within the sleeve 4.

[0028] Furthermore, the end of the sliding rod 11 is movably connected to the middle of the first end rod 8 via a pin, the end of the first end rod 8 is movably connected to the body of the intermediate rod 13 via a pin, and the end of the intermediate rod 13 is movably connected to the body of the end rod 10 via a pin.

[0029] Furthermore, the bottom of the connecting mounting plate 1 is symmetrically provided with columns 15, and the bottom ends of the columns 15 on both sides are fixedly connected with support plates 16.

[0030] Specifically, the ball collection and recycling net frame of this utility model adopts a multi-level linkage folding arm design, which allows the entire system to be folded into a smaller volume when not in use, thereby greatly saving storage and transportation space. This design makes the system easy to carry and move to different sites without complicated installation process.

[0031] Specifically, when the lead screw stepper motor 2 starts and rotates in the forward direction, the lead screw drives the slider 6 to move upward along its axis. As the slider 6 rises, the sliding rod 11 connected by the second lifting lug 7 is forced to rise as well. Since the end of the sliding rod 11 is movably connected to the middle of the first end rod 8 through a pin, the rise of the sliding rod 11 causes the bottom of the first end rod 8 to move away from the umbrella frame base 3. At the same time, the top of the first end rod 8 remains relatively fixed due to the constraint of the long traction rod 9, thereby creating an inward folding angle for the first end rod 8. One end of the long traction rod 9 is movably connected to the first end rod 8 through a pin, and the other end is connected to... The pin is movably connected to the end rod 10. As the folding angle of the first rod 8 increases, the long traction rod 9 is forced to bend, which in turn drives the end rod 10 to move inward and generate a folding angle. At the same time, the rise of the sliding rod 11 also drives the middle rod 13 to change its angle through the short traction rod 12. One end of the middle rod 13 is movably connected to the first rod 8 through the pin, and the other end is movably connected to the end rod 10 through the pin. This linkage mechanism further enhances the folding effect of the folding arm. As the multi-stage linkage folding arm folds, the various parts of the ball-collecting net 17 are gradually pulled closer and overlapped together, thereby realizing the contraction of the ball-collecting net 17.

[0032] When the lead screw stepper motor 2 rotates in the reverse direction, the lead screw drives the slider 6 to move downward along its axis. As the slider 6 descends, the sliding rod 11 also descends, causing the bottom of the first end rod 8 to move closer to the umbrella frame base 3. At the same time, the top of the first end rod 8 gradually returns to its original position due to the constraint of the long traction rod 9, thereby gradually reducing the folding angle of the first end rod 8 until it disappears. As the angle of the first end rod 8 returns to normal, the long traction rod 9 also gradually returns to a straight state, thereby driving the end rod 10 to move outward and return to its original position. Meanwhile, the descent of the sliding rod 11 also drives the middle rod 13 to return to its original angle position through the short traction rod 12. As the multi-stage linkage folding arm extends, the various parts of the ball-collecting net 17 are gradually pulled open and laid flat in the predetermined area, thereby achieving the complete unfolding of the ball-collecting net 17. Throughout the entire movement, the various components of the multi-stage linkage folding arm achieve uniform and controllable contraction and unfolding of the ball-collecting net 17 through a precise linkage mechanism.

[0033] In another embodiment provided by this utility model, such as Figure 5 As shown, several end rods 10 are equipped with ball-collecting nets 17 through the anchor points 14.

[0034] Furthermore, the ball-collecting net 17 is divided into an upper part and a lower part. The ball-collecting net 17 is woven from nylon material. The upper part is a hollow inverted square shape, and the lower part is a hollow cylinder shape.

[0035] Specifically, the ball-collecting net 17 is installed via anchor points 14 on the end rod 10. These anchor points 14 are carefully positioned on the end rod 10 to ensure that the ball-collecting net 17 can unfold evenly and stably. When the multi-stage linkage folding arm unfolds, the end rod 10 moves to the predetermined position and stretches the ball-collecting net 17 into the predetermined shape through the anchor points 14. This installation method not only simplifies the setup process of the ball-collecting net 17 but also improves its stability and durability. In actual use, the inverted square upper part of the ball-collecting net 17 can effectively capture incoming training balls and guide them to the center area of ​​the net. Subsequently, these balls will smoothly fall into the ball-release port at the bottom along the cylindrical lower channel. This design not only improves ball-collecting efficiency but also reduces the risk of ball loss and damage. At the same time, the nylon ball-collecting net 17 also has good durability and breathability, making the entire collection process smoother and more efficient.

[0036] In another embodiment provided by this utility model, such as Figure 6 As shown, this utility model is easy to carry and move to various occasions by combining with external devices.
