[0024] Reference Figure 1-3 The utility model provides an embodiment: a table tennis training device, including a body 1, the left and right sides of the bottom end of the body 1 are rotatably connected to support legs 2, the rear side of the bottom end of the body 1 is fixedly connected to a connecting leg 3, the top of the body 1 is fixedly connected to a first ball storage barrel 4, and the inside of the first ball storage barrel 4 is slidably connected to a second ball storage barrel 5.
[0025] Specifically, the body 1, the supporting legs 2, the connecting legs 3, the first ball storage barrel 4 and the second ball storage barrel 5 form an overall bracket structure, and the body 1 is fixed by the supporting legs 2 and the connecting legs 3, so that the body 1 will not shake during operation or be knocked down by the table tennis balls during training. The balls are transported into the body 1 through the first ball storage barrel 4 and the second ball storage barrel 5, so that the space for placing the table tennis balls is expanded, thereby enhancing the training effect of the body 1.
[0026] A mounting groove 6 is provided inside the connecting leg 3, and a bidirectional threaded rod 7 is rotatably connected inside the mounting groove 6. A rotating rod 8 is fixedly connected to the bottom end of the bidirectional threaded rod 7. The inside of the mounting groove 6 is rotatably connected to the outside of the rotating rod 8. The upper and lower sides of the outside of the bidirectional threaded rod 7 are threadedly connected to threaded sleeves 9. The inside of the mounting groove 6 is slidably connected to the outside of the threaded sleeve 9. A clamping block 10 is fixedly connected to the front end of the threaded sleeve 9, and the inside of the mounting groove 6 is slidably connected to the outside of the clamping block 10.
[0027] Specifically, the mounting groove 6 limits the bidirectional threaded rod 7 and the rotating rod 8, so that the bidirectional threaded rod 7 and the rotating rod 8 are stable when rotating. The mounting groove 6 limits the threaded sleeve 9 and the clamping block 10, so that the threaded sleeve 9 and the clamping block 10 will not deviate when moving. By rotating the rotating rod 8, the bidirectional threaded rod 7 is driven to rotate, and then the two threaded sleeves 9 are driven to move toward one end, thereby driving the clamping block 10 to move with it, and then the clamping block 10 clamps the table, so that the body 1 is fixed, and then the body 1 is stable during operation and will not be knocked down by the table tennis ball.
[0028] A buckle assembly 11 is provided inside the second ball storage barrel 5, and the buckle assembly 11 includes two clamping grooves 1102, which are respectively opened on the left and right sides of the interior of the second ball storage barrel 5, and a clamping block 1101 is slidably connected inside the clamping groove 1102. A reset assembly 12 is provided inside the first ball storage barrel 4, and the reset assembly 12 includes two limit grooves 1201, which are respectively opened on the left and right sides of the interior of the first ball storage barrel 4, and the inner wall of the limit groove 1201 is fixedly connected with a spring 1202, and the proximal ends of the two springs 1202 are fixedly connected to the limit block 1203, and the separated ends of the two clamping blocks 1101 are fixedly connected to the proximal ends of the two limit blocks 1203, and the interior of the limit groove 1201 is slidably connected to the exterior of the limit block 1203.
[0029] Specifically, the limiting groove 1201 and the limiting block 1203 fix the spring 1202, so that the spring 1202 is stable when elastically deformed, and the limiting groove 1201 limits the limiting block 1203 and the clamping block 1101, so that the limiting block 1203 and the clamping block 1101 will not deviate when moving, and the limiting groove 1201 limits the limiting block 1203, so that the clamping block 1201 will not be separated from the limiting groove 1201, and the clamping block 1101 moves and engages in the clamping groove 1102, so that the position of the second ball storage barrel 5 is fixed, and the second ball storage barrel 5 is moved upward, so that the two clamping blocks 1101 move toward the separated ends, thereby driving the limiting block 1203 to move. 203 moves with it, thereby squeezing the spring 1202 to make elastic deformation, and then when the second ball storage barrel 5 moves to a suitable position, the spring 1202 performs a reset activity, thereby driving the two limit blocks 1203 to move toward the adjacent end, thereby driving the clamping block 1101 to move with it into the clamping groove 1102, thereby making the clamping block 1101 engage with the clamping groove 1102, so that the position of the second ball storage barrel 5 is fixed, and by moving the second ball storage barrel 5 downward, the two clamping blocks 1101 move toward the separated end, thereby making the clamping block 1101 disengage from the clamping groove 1102, so that the second ball storage barrel 5 moves downward to the inside of the first ball storage barrel 4, so as to facilitate its carrying.
[0030] Working principle: When the ball table needs to be clamped so that the body 1 is fixed, the rotating rod 8 is rotated to drive the bidirectional threaded rod 7 to rotate, thereby driving the two threaded sleeves 9 to move toward the end close to each other, thereby driving the clamping block 10 to move with it, and then the clamping block 10 clamps the ball table, so that the body 1 is fixed. When the pinball container needs to be expanded, the second ball storage cylinder 5 is moved upward, so that the two clamping blocks 1101 move toward the separated end, thereby driving the limit block 120 3 moves with it, thereby squeezing the spring 1202 to make elastic deformation, and then when the second ball storage tube 5 moves to a suitable position, the spring 1202 performs a reset activity, thereby driving the two limit blocks 1203 to move toward one end, thereby driving the clamping block 1101 to move with it into the clamping groove 1102, and then the clamping block 1101 is engaged with the clamping groove 1102, so that the position of the second ball storage tube 5 is fixed, and then the pinball container can hold more table tennis balls, thereby reducing the frequency of filling during training.
