(7) Referring to FIGS. 2 and 3, specifically when the frame 1 unfolded, for example, the frame 1 includes three first elbows 11 and four second elbows 12. The first elbows 11 and the second elbows 12 are all U-shaped. The three first elbows 11 are connected in sequence, in which two adjacent first elbows 11 are horizontally arranged, ends of the two first elbows 11 are facing each other and hinged to each other. In addition, the other first elbow 11 extends obliquely, and two ends of the oblique first elbow 11 are hinged to one of the horizontal first elbows 11. The oblique first elbow 11 extends obliquely upwards and away from the horizontal first elbow 11, to which the oblique first elbow is hinged.

(8) Further, two of the four second elbows 12 are respectively hinged to the two horizontal first elbows 11, specifically, ends of the two second elbows 12 are hinged to the two horizontal first elbows 11, correspondingly. The two second elbows 12 are located at the front and rear ends of the frame 1, respectively. At the same time, another second elbow 12 is hinged at a connection between the two horizontal first elbows 11, that is, the another second elbow 12 is located between the two second elbows 12 mentioned above, and the remaining second elbow 12 is hinged to the oblique first elbow 11.

(9) Therefore, when the ball pitching device is lying idle, the second elbows 12 may be rotated, so that each second elbow 12 abuts against the corresponding first elbow 11, respectively, and then the first elbows 11 are rotated, so that the first elbows 11 are stacked correspondingly, thereby reducing the space occupancy of the whole frame 1, making the device easy to fold and store when not in use.

(10) Specifically, connection sockets 6 are provided between two adjacent first elbows 11 and between the first elbow 11 and the second elbow 12, respectively, and the connection socket 6 is hinged to the first elbow 11 or the second elbow 12 through pins. The connection sockets 6 between the two adjacent horizontal first elbows 11 are T-shaped connection elements, each of which has three connection ends, two of the three connection ends are hinged to the two horizontal first elbows 11 through corresponding pins, and the other connection end is configured to be hinged to one of the second elbows 12. In addition, the connection sockets 6 between the oblique first elbow 11 and any one of the horizontal first elbows 11 are L-shaped connection elements, and similarly, the connection sockets 6 between the second elbows 12 and the first elbows 11 are also L-shaped connection elements.

(11) Therefore, by means of the connection sockets 6 and the pins, the stability of the device can be increased, the fixation effect of the pin can ensure the firm connection between the connection socket 6 and the first elbow 11 or the second elbow 12, reducing the possibility of shaking and loosening, thereby improving the stability of the device. In addition, by means of the connection sockets 6 and the pins, different parts of the device can be conveniently disassembled and maintained. If it is necessary to make reparation or replacement, relevant parts can be easily separated by detaching the pin, to carry out the necessary reparation or replacement.

(12) On the other hand, in order to improve the stability of the oblique first elbow 11, the present application further adopts the following solution.

(13) Specifically, a support rod 7 is provided between one of the second elbows 12 and the oblique first elbow 11, one end of the support rod 7 is hinged to the oblique first elbow 11, and the other end of the support rod 7 is detachably connected to the one of the second elbows 12.

(14) Correspondingly, by means of the support rod 7, the stability of the whole device may be increased, which provides an additional support, such that the second elbow 12 is more firmly connected with the oblique first elbow 11. At the same time, the position of the hinge point between the support rod 7 and the oblique first elbow 11 is modified, or the support rods 7 of different lengths are chosen, such that the inclination angle can be adjusted, and the inclination degree can be self-defined according to needs, to adapt to different usage scenarios or personal preferences.

(15) Further, a side wall of the second elbow 12 is fixedly provided with a limit block 121, and the support rod 7 is configured with a plurality of limit openings 71 at intervals along its own length direction, and the limit block 121 is engaged with one of the limit openings 71.

(16) Therefore, the limit opening 71 is engaged with the limit block 121, such that the support rod 7 can be firmly fixed at a selected position. Since there are a plurality of limit openings 71, the angle of the support rod 7 can be adjusted many times as needed. By selecting different limit openings 71, the angle between the support rod 7 and the oblique first elbow 11 and the second elbow 12 can be changed, thereby adjusting the inclination degree, to adapt to different usage scenarios and angle requirements.

(17) Further, the second elbow 12 is fixedly provided with a foot brace 122, which is configured for contacting with the ground. The foot brace provides an additional stable support, making the entire ball pitching device more stable during use. The foot brace 122 may disperse the weight of the device and increase the support area due to the contact with the ground, thereby improving the stability of the device and preventing it from shaking or inclining during use.

(18) Referring to FIGS. 1 and 4, on the other hand, an edge of the upper PVC sheet 2 is provided with a sleeve 22, two ends of the sleeve 22 are open. The first elbow 11 extends through the sleeve 22, to achieve the fixation between the upper PVC sheet 2 and the frame 1. At the same time, the upper PVC sheet 2 is configured with a hole 21. In the embodiment, six holes 21 are provided, three of which are arranged horizontally at intervals, and the other three holes are arranged vertically at intervals. In addition, the lower PVC sheet 3 is located below the upper PVC sheet 2, the lower PVC sheet 3 is fixedly connected with the upper PVC sheet 2. A ball storage space 8 is formed between the lower PVC sheet 3 and the upper PVC sheet 2. That is, after the ball passes through the hole 21, it enters the ball storage space 8 and is held by the lower PVC sheet 3.

(19) Correspondingly, when the upper PVC sheet 2 is connected with the first elbow 11, a part of the upper PVC sheet 2 extends horizontally while the other part of the upper PVC sheet 2 extends obliquely since one of the first elbows 11 extends obliquely, and the holes 21 are correspondingly defined in the oblique part.

(20) Further, for the fun of the device, an infrared sensor 9 is provided inside the hole 21, which is fixed relative to the lower PVC sheet 3. A screen displaying score 10 is provided on the second elbow 12, which is connected with the infrared sensor 9.

(21) When a player pitches a ball into the hole 21, the infrared sensor 9 will detect an entry of the ball. The sensor can detect a presence of the ball or determine whether the ball enters the hole 21 by change of light. Once the infrared sensor 9 detects the entry of the ball, the infrared sensor 9 will send a signal to the screen displaying score 10, which receives the signal from the infrared sensor 9 and records the corresponding score on the screen displaying score 10.

(22) In addition, the surface of the upper PVC sheet 2 is fixedly provided with a fence 23, which is arranged around several holes 21. Specifically, two fences 23 are provided, one of the two fences 23 is circular, and the other fence 23 is U-shaped. One of the two fences 23 extends around the outside of the two holes 21 which are arranged vertically, and the other fence 23 is located below the previous fence 23.

(23) Therefore, the ball may enter the hole 21 enclosed by the fence 23 due to the guidance of the fence 23, thereby improving the field goal percentage of the ball and indirectly improving the user experience.

(24) On the other hand, in order to improve the user experience during pitching, a side net 4 is correspondingly provided in the embodiment of the present application.

(25) Specifically, two side nets 4 are provided, which are located on two sides of the frame 1. The side net 4 is provided with buckles 41, which are snapped into the connection sockets 6, such that the side nets 4 may block part of the space on the left side and right side of the upper PVC after the side nets 4 are erected.

(26) Therefore, two side nets 4 may intercept the balls that bounce to outside of the device due to collision, so as to prevent the balls from rolling out of the device range, which allows users to focus more on the game without concerning about the loss of the balls or the impact of the balls on other objects.

(27) Further, the collection basket 5 is provided at a tail end of the frame 1, which includes a basket body 51 and a mesh cloth 52. The basket body 51 is rotatably supported on the first elbow 11, and the mesh cloth 52 is fixed to a side wall of the basket body 51, the mesh cloth 52 and the basket body 51 are enclosed to form the collection basket 5 opened upwards. At the same time, the collection basket 5 is located on the open end of the ball storage space 8.

(28) Therefore, when the balls enter the device but do not enter the holes 21, they will be guided to a rear collection basket 5. By the basket body 51 and the mesh cloth 52, the collection basket 5 can effectively hold the balls, so as to prevent the balls from rolling out of the device and reducing the loss of the balls.

(29) At the same time, the mesh cloth 52 makes the collection basket 5 semi-transparent, such that it is easy for users to see the goals from a side.

(30) Further, the lower PVC sheet 3 extends obliquely from an end facing the holes 21 towards an end facing the collection basket 5.

(31) Therefore, the end of the lower PVC sheet 3 facing the holes 21 is inclined, such that the balls may be guided to roll downward along an inclined surface and move towards the end facing the collection basket 5, making the balls smoothly roll into the collection basket 5, which improves the accuracy and reliability of the balls entering the collection basket 5.

(32) The implementation principle of the ball pitching device in the embodiment of the application is as follows.

(33) When the ball pitching device is lying idle, the second elbows 12 are rotated, so that each second elbow 12 abuts against the corresponding first elbow 11, and then the first elbows 11 are rotated, so that the first elbows 11 are stacked correspondingly, thereby reducing the space occupancy of the frame 1 in whole, so as to fold and store the device conveniently when not in use.

(34) The above are the preferred embodiments of the present application, which are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
