Detailed Description

The technical scheme of the invention is further explained in detail by combining the attached drawings:

a table tennis sleeve bag is shown in figure 1 and comprises an outer shell 1 and an inner shell 2, the upper end of the outer shell is closed, a latch 21 is arranged in the inner shell 2, a spring III 211 is arranged in the latch 21, telescopic teeth 212 are arranged at two ends of the latch 21, the telescopic teeth 212 can extend out of the latch 21 under the action of the spring III 211, a plurality of clamping grooves are uniformly distributed in the side wall of the inner shell 2, the telescopic teeth 212 can be inserted into the clamping grooves to limit the movement of the latch 21 in the inner shell 2, and a spring II 22 for driving the latch 21 to move is arranged between the top of the inner shell 2 and the latch 21; the lower end of the inner shell 2 is provided with an elastic catch 23 for blocking the table tennis.

A telescopic sleeve 3 is further arranged between the outer shell 1 and the inner shell 2, a first spring 31 for driving the telescopic sleeve 3 to slide in the outer shell 1 is arranged at the top of the telescopic sleeve 3, a plurality of pushing teeth 32 are uniformly distributed on the inner side wall of the telescopic sleeve 3, the pushing teeth 32 are the same in number with the clamping grooves, and the positions of the pushing teeth 32 and the clamping grooves are staggered one by one; one side of flexible tooth 212 towards spring 31 is provided with inclined plane 213, and when telescopic sleeve 3 moved towards shell 1 upper end, push tooth 32 can push flexible tooth 212 in the latch 21, the lower extreme of telescopic sleeve 3 stretches out shell 1 and is provided with trigger 33.

The upper end of the shell 1 is detachably connected with a sealing cover 4. A rotary clamping groove 41 is formed in the sealing cover 4, and the sealing cover 4 is fixedly connected with the shell 1 through being screwed into the rotary clamping groove 41. A handle 42 is provided on the cover 4. The removable cover 4 facilitates removal of the spring and latch 21 for filling the table tennis ball.

The elastic separation blades are made of plastic materials and are circumferentially and uniformly distributed on the side wall of the inner shell 2, and the elastic separation blades transversely extend from the side wall of the inner shell 2 towards the axis of the inner shell 2.

Description of specific embodiments:

before the table tennis bat is used, table tennis balls are firstly filled into the inner shell 2 in the following filling mode: the cover 4 is disassembled, the second spring 22 and the latch 21 are taken out, then the inner shell 2 is filled with table tennis balls, and finally the second spring 22, the latch 21 and the cover 4 are reinstalled. After the table tennis balls are filled, the table tennis ball is bound on the front arm of a user, and therefore, a binding belt can be arranged on the shell 1 of the table tennis ball, and the table tennis ball is convenient to bind; in the binding, the end with the trigger 33 is directed towards the wrist and the trigger 33 is located just at the wrist.

When in use, a user bends the wrist and makes the palm under the lower end of the inner shell 2, and makes a ball-catching gesture. When the user bends the wrist, the force of the wrist will press the trigger 33, thereby pushing the telescopic sleeve 3 towards the upper end. At this moment, no matter which clamping groove the clamping tooth 21 is in, a corresponding pushing tooth 32 pushes the telescopic tooth 212 into the clamping tooth 21, so that the clamping tooth 21 is separated from the limiting of the clamping groove, then moves towards the lower end of the inner shell 2 under the action of the second spring 22, meanwhile pushes the table tennis ball downwards, the table tennis ball at the lowest position is pushed out of the inner shell 2 and then falls into the hand of a user, the telescopic tooth 212 of the clamping tooth 21 also enters the next clamping groove at the same time, and the clamping tooth 21 is limited to move again. And the user, after receiving the ball, straightens the bent wrist, so that the trigger 33 loses the pushing force of the wrist and then is immediately restored under the action of the first spring 31.
