Abstract

The invention discloses a table tennis ball collecting device for assisting in training. The device comprises a ball collecting device, a ball feeding device and a supporting device, the ball collecting device comprises a main body ball collecting nylon net and side wing ball collecting nylon nets on the two sides, the ball feeding device comprises a cloth funnel-shaped storage bag, a first guidepipe and a second guide pipe, and the supporting device comprises a hook-shaped supporting rod, a cuboid supporting rod, a nylon net supporting component and the like. When a trainee performs ball serving training, the main body ball receiving nylon net and the side wing ball receiving nylon net can buffer rotation and impact of the ball, and finally the ball returns to the trainee through the cloth funnel-shaped storage bag and the extension state guide pipe. When a trainee performs multi-ball training, the guide pipe is contracted and rotated to a coach for conveying multiple balls, so thatthe balls return to the coach. According to the invention, the ball picking time is reduced, and the training efficiency is improved. When not in use, the device can be detached and restored into a common table tennis table, and the device can be folded and stored to save space.

[0023] The present invention will be further described below in conjunction with accompanying drawing:
[0024] like Figure 1-5 Shown, a kind of table tennis ball collecting device of auxiliary training comprises ball collecting device, ball sending device and supporting device; Wherein,
[0025] The support device includes a support rod support part 2, an upper fixed support rod 1, two support folding rods 8, two opening and closing support rods 9, two cuboid support rods 11, two hook-shaped support rods 12, two Net frame 5 and two bolts 6, the upper fixed support rod 1 is vertically fixed at the center of the support rod support part 2, and the two opening and closing support rods 9 are respectively connected to the support rod support part 2 in rotation , and symmetrically arranged on both sides of the upper fixed support rod 1, the two support folding rods 8 are respectively installed on the two ends of the support rod support part 2 through hinges 2-6, and the two cuboid support rods 11 are respectively Fixedly installed on the side of the support rod support part 2, and the two cuboid support rods 11 are symmetrically arranged, respectively located on both sides of the upper fixed support rod 1, and the two hook-shaped support rods 12 are respectively fixed on The bottom end of the support member 2 of the support rod, and the two hook-shaped support rods 12 are arranged symmetrically, and are respectively located on both sides of the upper fixed support rod 1. 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.
