On both sides of table 14;
[0026] Described table tennis ball delivery device comprises first conduit 13 and second conduit 7, and described first conduit 13 and second conduit 7 all are the cone-shaped conduits of upper end internal diameter greater than lower end internal diameter, and described second conduit 7 is sleeved on In the first conduit 13, a telescopic conduit is formed;
[0027] The ball collecting device comprises a main body nylon net 3, two side wing nylon nets 4, and a cloth funnel-shaped storage bag 10; The side-wing nylon nets 4 are symmetrically arranged on both sides of the main body nylon net respectively, and one end of the side-wing nylon nets 4 is connected to the main body nylon net 3, and the other end is set on the grid frame 5; the cloth funnel-shaped storage bag 10 two The ends are respectively placed on the two supporting folding rods 8, and the ball outlet at the lower end of the cloth funnel-shaped storage bag is connected with the upper end of the first conduit 13.
[0028] Preferably, the inner diameter of the upper end of the first conduit 13 is 55mm, and the inner diameter of the lower end is 45mm; the inner diameter of the upper end of the second conduit 7 is 48mm, and the inner diameter of the lower end is 43mm.
[0029] Preferably, as Figure 6-7 As shown, the support rod supporting part 2 includes a cuboid support 2-1, and two symmetrically arranged rectangular grooves 2-2 are opened on the upper end surface of the cuboid support 2-1, and the rectangular groove 2-2 A group of circular through-holes 2-4 are opened on both sides opposite to one end of the trough, and a square groove 2-5 is opened at the bottom of one end of the rectangular groove 2-2, and the square groove 2-5 is connected to the The circular through hole 2-4 corresponds, the other end of the rectangular groove 2-2 is connected with the support folding rod 8 through the hinge 2-6, and the bottom end of the opening and closing support rod 9 has a rectangular through hole 2 -3, and the bottom end of the opening and closing support rod 9 is rotatably connected to the circular through hole 2-4 through the rectangular through hole 2-3, and the internal structure of the two rectangular slots 2-2 is the same. In the present invention, when the opening and closing support rod 9 is put away, the bottom end of the opening and closing support rod 9 is positioned in the square groove 2-5 to form a fix; The rectangular through hole 2-3 is pulled out from the square groove 2-5, and the space of the rectangular through hole 2-3 is used to realize the rotation around the axis of the opening and closing support rod 9.
[0030] Preferably, both the first conduit 13 and the second conduit 7 are light material conduits, the first conduit 13 is connected to the lower end of the cloth funnel-shaped storage bag by a bendable telescopic conduit, and the lower end of the first conduit 13 is One end of a thin rope is connected, and the other end of the thin rope is connected with a sheet-shaped hard board, and the thin-sheet-shaped hard board is inserted into a gap in the middle of the table tennis table and placed horizontally for fixing the first conduit 13 .
[0031] Preferably, the hinges 2-6 are 90° opening and closing hinges.
[0032] Among the present invention, the concrete installation mode of table tennis ball collection device is as follows:
[0033] Will Figure 4 As shown, it is the table tennis ball collection device in the retracted state. First, the first conduit 13 and the second conduit 7 are folded down so that they are located below the table tennis table 14, and the second conduit 7 is removed from the first conduit 13. Pull it out to the actual required length and fix it (the fixing method belongs to conventional technical means, and those skilled in the art can realize the fixing of the catheter according to actual needs, so it is not described in detail).
[0034] Then the cuboid support rod 11 is placed on the table tennis table 14, two hook-shaped support rods 12 walk around the side flange of the table tennis table 14, lean against the lower end of the table tennis table 14 desktop, and cooperate with the cuboid support rod 11 And rely on device self weight that device is fixed on the ping-pong table 14. Then the two support folding rods 8 are opened through the hinges 2-6, and at the same time, the two opening and closing support rods 9 are pulled out from the square grooves 2-5 of the support rod support part 2 to rotate, and the support rods are fixed upward. 1 open on both sides and unfold to form as figure 1status shown. The main body nylon mesh 3 is socketed on the two supporting folding rods 8, the opening and closing supporting rod 9 and the upper fixed supporting rod 1, so that the main body nylon mesh 3 can be effectively opened, and the fabric funnel-shaped storage bag 10 is socketed under the supporting folding rod 8 , and the outlet at the lower end of the cloth funnel-shaped storage bag 10 is connected to the lower end of the first conduit 13;
[0035] Finally, the two grids 5 are respectively symmetrically fixed on both sides of the table tennis table 14 by bolts 6, and the two flank nylon nets 4 connected to the two sides of the main body nylon net 3 are respectively sleeved on the two grids 5. The invention installation process is complete.
[0036] like figure 2 Shown, is the installation state of this device when trainer carries out serving training, promptly when trainer is positioned at table tennis table 14 service areas one side, when trainer sends ball, ball hits the side wing nylon net 4 of ball receiving device Or when the main body nylon net 3 is on, the elasticity of the nylon net is used to absorb the rotation and strength of the table tennis ball, the table tennis ball is buffered, and the table tennis ball is rolled into the cloth funnel-shaped storage bag 10, and due to its own gravity, the table tennis ball passes through the first conduit successively After 13 and the second conduit 7, roll out steadily, fall in the ball basket of trainer's position.
[0037] like image 3 Shown, the installation state of this device when the trainer carries out multi-ball training, promptly the trainer is positioned at 14 hitting area sides of the table tennis table, and the coach is positioned at the long side middle position of the table tennis table, when the coach puts the table tennis After the ball is delivered to the trainer, the trainer hits the table tennis ball back at a high speed. When the table tennis ball is hit on the side nylon net 4 or the main body nylon net 3 of the ball receiving device, the elasticity of the nylon net is used to absorb the rotation and strength of the table tennis ball, and The table tennis is buffered, and the table tennis rolls into the cloth funnel-shaped storage bag 10. Due to its own gravity, the table tennis rolls out smoothly after passing through the first conduit 13 and the second conduit 7 successively, and falls into the coach's position.
[0038] The specific embodiments described above have further described the technical problems, technical solutions and beneficial effects solved by the present invention in detail. It should be understood that the above descriptions are only specific embodiments of the present invention and are not intended to limit the present invention. Inventions, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
