That is, the ball shooting device 10 includes a ball seating portion 450 in which a ball is seated in a space spaced forward from the target 610, and a ball seated on the ball seating portion 450 And is capable of being hit so that the ball of the ball seating portion 450 is emitted toward the target 610 under the control of the controller 200 provided at the front.

Referring to FIGS. 2 and 3, a detailed view of the rear surface coupling area between the controller and the duct of the present invention and the coupling relationship between the entire disk rotation and the duct of the present invention shown in FIG. 3, The apparatus 10 transmits the compressed air generated by the punching ball 2200 and the punching ball 220 to the cylinder 30 that generates compressed air by the blow and constitutes the piston 33 of the cylinder 30 to strike the ball .

The cylinder 30 includes a piston 33 disposed at a lower portion of the ball seating portion 450 and capable of flowing upward and downward by the compressed air. The cylinder 30 includes a piston 30 for transmitting compressed air of the punching ball 220 to the cylinder 30, The member 300 is connected to the back surface of the controller 200 and the lower portion of the ball seating portion 450.

First, the controller 200 configures the user to control the ball to be launched.

In the present invention, the controller 200 is constituted by a punching ball 220 having a restoring force, compressed air is generated by striking the punching ball 220, and when the generated compressed air flows into the cylinder 30 and hits the piston 33 , So that the upper piston rod 33b is fired at a ball.

In addition, the controller 200 may be provided with various buttons for using a ball shooting device.

The configuration of the controller 200 will be described in detail with reference to the drawings for explaining the operation of the punching ball of the present invention shown in Figs.

5, a hollow auxiliary bracket 242 is coupled to the outer circumferential surface of the air intake port 260 by a coupling member 240 on the upper surface of the base plate 210 on which the air intake port 260 is formed.

The coupling member 240 is threaded and formed with a thread at one end to connect the back surface of the auxiliary bracket 242 to the outer circumferential surface of the air inlet 260. The portion where the screw head is formed is not formed with the auxiliary bracket 242 And a thin film 230 is interposed between the upper surface and the screw head to move up and down.

That is, the coupling member 240 may be a book-like screw in the form of a semi-thread (fabric cap bolt, head cap bolt).

4, the coupling member 240 is partially fixed to the base plate 210 by screwing, and a thin film 230 is formed between the upper surface of the base plate 210 and the screw head of the coupling member 240 Respectively.

The thin film 230 normally covers the upper surface of the base plate 210 due to its own weight. When the punching ball 220 is charged, the punching ball 220 is pressed, and the compressed air presses the upper surface of the thin film 230 The thin film 230 covers the upper surface of the air inlet 260 and prevents the air from escaping. As a result, the compressed air is discharged to the compressed air outlet 250.

6, when the punching ball 220 is pushed and pressed, the air remaining in the punching ball 220 becomes compressed air, thereby pressing the upper portion of the thin film 230 in the arrow direction more reliably to block the air inlet 260 The compressed air is discharged to the compressed air discharge port 250.

The thin film 230 of the air intake port 260 opens the air intake port 260 by the restoring force of the punching ball 220 so that the air flows into the inside of the punching ball 220 Restoration is easy.

Referring to FIG. 7, the thin film 230 rises in the space x from the upper surface of the auxiliary bracket 242 to the screw head, and opens the inlet of the air intake port 260 to allow air to flow.

The outer circumferential surface of the punching ball 220 must be in close contact with the auxiliary bracket 242 so as to prevent the inflow and outflow of air. Therefore, the outer circumferential surface of the coupling portion 222).

In addition, the punching ball 220 should be operated to reduce the volume of the air contained therein because the punching ball 220 is easily distorted by external pressure or price.

In addition, the punching ball 220 is formed of a rubber material having elasticity of a constant thickness in the vicinity of the vertex, and has a thicker thickness from the vertex to the outer circumference.

Referring to FIG. 4, it can be seen that the thickness increases from the outer circumferential surface of the punching ball 220 to a certain height y1.

With this configuration, even if the punching ball 220 is pressed and the vertex P 2 is distorted and compressed, the upper portion of the punching ball can be quickly restored.

Referring to FIG. 6, the urged vertex P2 can be quickly restored as shown in FIG. 7 while air is sucked through the air inlet 260.

The punching ball 220 and the cylinder 30 are coupled to each other by the duct member 300 so that the punching ball 220 is pressed and discharged without damaging the cylinder 30 as much as possible, do.

To this end, the duct member 300 is in tight contact with the compressed air outlet port 250 of the controller 200, and the duct member 310 is connected to the tubular duct 310 for transmitting the compressed air of the controller 200 to the cylinder 30, The cylinder 30 is hermetically fixed.

In addition, the duct member 300 of the present invention can be easily separated from the controller 200, so that the controller 200 can be separated from the duct member 300, if necessary, and the interior of the duct member 300 can be repaired or inspected.

To this end, one end of the duct 310 is tightly coupled with or separated from the compressed air outlet 250 of the controller 200, and the coupling portion is press-coupled by the sealing member 320, .

Referring to FIG. 2, the sealing member 320 is press-coupled with the back surface of the compressed air discharge port 250 so as to be folded or separated.

Therefore, in order to maximize the sealing effect, the sealing member 320 is fixed to the one end of the duct 310 with an adhesive so as to be completely sealed, and the other surface is sealed with the back surface of the compressed air outlet 250 by the folding operation of the controller 200 It is preferable to make them to be combined.

Further, a sealing member 212 such as a rubber material is attached to the back surface of the compressed air discharge port 250 so that they are pressed against each other to be sealed.

In order to prevent this, the cylinder 30 of the present invention has a tubular guide tube 32 into which an upper rod cover 35 and a piston 33 which flows upward and downward are inserted into the lower rod cover 330, And an upper piston rod 33b and a lower piston rod 33a which are respectively inserted into the rod holes 35a and flow up and down.

Although the lower rod cover 330 is illustrated as being formed at one end of the duct 310 in the present invention, it may be formed at the lower portion of the cylinder 30 as a matter of course.

Reference numerals 31 and 34 denote sealing members for preventing the loss of compressed air when the upper rod cover 35 and the lower rod cover 330 are coupled to the upper and lower portions of the guide tube 32, respectively.

Referring to FIG. 12, the upper piston rod 33b and the lower piston rod 33a are vertically coupled with respect to the circular compression plate 33e.

The compression plate 33e is inserted into the center of the integrally formed piston rod and fixed by the upper and lower fixing pins 33c and 33d.

The outer surface of the compression plate 33e is configured to be in close contact with the inner wall of the cylinder or guide tube 32 so that compressed air does not flow out into the gap, It should be configured to rise quickly by air.

The piston rods are raised and lowered through the rod holes formed at the center of the upper and lower rod covers to center the piston rod so that the upward and downward movements can occur rapidly in the guide tube 32. [

Meanwhile, a spring (not shown) may be inserted into the upper piston rod 33b so that the upper piston rod strikes the ball and quickly returns to the original position.
