The rotating part can be used to make the existing planar net surface changeable to a net surface with corners, so as to achieve the rebound requirements of different angles on the same net surface at the same time, so as to meet different rebound requirements.

[0005] Furthermore, in order to adjust the number and position of the corners of the mesh surface as needed, the rotating part is arranged at the upper end of the fixed part or at the lower end of the fixed part or at both ends of the fixed part.

[0009] Furthermore, the limiting mechanism includes limiting holes penetrating the mounting portion, the limiting holes are arranged at intervals along the rotation path of the rotating portion, the mounting portion is provided with a latch passing through the limiting hole, and the rotating portion is provided with a latch hole cooperating with the latch.

[0010] Furthermore, universal wheels are arranged at intervals at the lower end of the base to facilitate the movement of the rebounding net.

[0016] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0017] Embodiment 1, as Figure 1-3As shown, the structure of this embodiment is: a multi-angle rebound net, which includes a frame and a net surface 1, the net surface 1 can be made of PE material, and its edge is hemmed, and multiple groups of binding straps are arranged along the edge of the side of the net surface, and each group of binding straps is composed of two elastic ropes, one elastic rope is provided with a spherical spring buckle, and the other elastic rope passes through the spherical spring buckle, and the two elastic ropes are tied to the frame, so as to tie the net surface to the frame. The frame includes support columns 2 which are arranged at intervals at the upper end of the base along the lateral direction, and universal wheels 12 are arranged at intervals at the lower end of the base, and the universal wheels 12 are equipped with brakes; side columns are arranged on the support columns 2, and the left and right sides of the mesh surface 1 are installed on the side columns, and the side columns include a fixed part 3 and a rotating part 4, the fixed part 3 is fixedly connected to the support column 2 through a branch pipe, and the rotating part 4 is either arranged at the upper end of the fixed part 3 or at the lower end of the fixed part 3 or at both the upper and lower ends of the fixed part 3. In the embodiment, the rotating part 4 is simultaneously arranged at both the upper and lower ends of the fixed part 3. In order to install the rotating part 4, a mounting part 5 is arranged on the fixed part 3, and the mounting part 5 is connected to the rotating part 4 through a rotating shaft. The rotating part 4 can be rotated to the same direction as the fixed part 3, and the rotating parts 4 on both sides are connected by a transverse beam 6, and the mesh surface 1 is installed on the transverse beam 6. The support column 2, the fixed part 3, the rotating part 4 and the transverse beam 6 can be made of metal round tubes. The rotating part 4 and the transverse beam 6 can be welded and fixed, or a mounting hole can be set on the rotating part 4. When in use, one end of the transverse beam 6 is inserted into the rotating part 4 to combine them together. When not in use, the transverse beam 6 is removed for easy storage.

[0018] The mounting portion 5 is provided with a limiting mechanism for fixing the rotation angle of the rotating portion 4. The limiting mechanism may be an existing mechanism such as a locking bolt. In this embodiment, the limiting mechanism includes a limiting hole 10 penetrating the mounting portion 5. The limiting holes 10 are arranged at intervals along the rotation path of the rotating portion 4. The mounting portion 5 is provided with a latch 11 passing through the limiting hole 10, and the rotating portion 4 is provided with a latch hole matched with the latch 11. An internal thread may be provided in the latch hole, and the latch 11 is provided with an external thread matched with the internal thread.

[0019] Specific usage method: The left and right sides of the mesh 1 are fixed on the fixed part 3 and the rotating part 4 of the side column, and the upper and lower sides of the mesh 1 are fixed on the transverse beam 6, so that the mesh 1 is fully unfolded. When the mesh 1 is unfolded in a plane, it is a square or a nearly square shape. This not only makes the rebound force generated by each edge of the mesh 1 tend to be consistent, but also greatly reduces the rebound force reduction caused by the mesh 1 being too long and the rebound amplitude being too large.

[0020] When the bending angle of the mesh surface 1 needs to be adjusted, the latch 11 is removed from the mounting portion 5, and then the rotating portion 4 is swung to a certain angle as required, and then the latch 11 is reinserted into the mounting portion 5 and inserted into the latch hole on the rotating portion 4, so that the mesh surface is at a certain angle.

[0021] Embodiment 2, as Figure 1-3 As shown, the other structures and methods of use of this embodiment are the same as those of embodiment 1, but in this embodiment, in order to further facilitate storage and use, the base comprises supports 7 disposed on the left and right sides of the mesh surface 1, the supports 7 can be square tubes, and the supports 7 on both sides are connected by reinforcing beams 8, and the reinforcing beams 8 and the transverse beams 6 are both formed by at least two hollow sleeves 9 being nested. This embodiment is illustrated with two sleeves 9. For the convenience of description, the two sleeves 9 constituting the reinforcement beam 8 are named reinforcement beam sleeve No. 1 and reinforcement beam sleeve No. 2, respectively. One ends of reinforcement beam sleeve No. 1 and reinforcement beam sleeve No. 2 are respectively installed on the supports 7 on both sides, and the other end of reinforcement beam sleeve No. 1 is inserted into reinforcement beam sleeve No. 2. The two sleeves 9 constituting the transverse beam 6 are named cross beam sleeve No. 1 and cross beam sleeve No. 2, respectively. One ends of cross beam sleeve No. 1 and cross beam sleeve No. 2 are connected to the rotating parts 4 on both sides, and one end of cross beam sleeve No. 1 is inserted into cross beam sleeve No. 2. The two sleeves are coaxially matched, and matching positioning holes and elastic positioning parts are provided on the adjacent two sleeves 9, wherein the positioning hole is provided in the outer sleeve 9, and the elastic positioning part is provided in the inner sleeve 9, and the elastic positioning part can adopt a spring buckle.

[0022] Specific usage method: during training, the reinforcing beam 8 and the transverse beam 6 are pulled apart, and the marbles on the spring buckle are inserted into the positioning holes; after the training is completed, the marbles on the spring buckle are pressed down, and then the reinforcing beam 8 and the transverse beam 6 are extended and retracted, that is, one sleeve 9 moves inwardly of another sleeve 9 in the same group, so that the frame can be folded to reduce the floor space occupied when stored.
