[0035] Further, the edge of the ball outlet 1 is provided with a sliding rail 8 for sliding cooperation of the anti-pinch door 3.

[0036] The working principle of the utility model is:

[0037] As an embodiment 1, the game scene of the application takes throwing a ping-pong ball as an example, for example, when the door body assembly is opened relative to the collection box 1-1, the ping-pong ball will fall from the ball outlet 1 of the collection box 1-1 into the game bin 1-2, when the door body assembly is closed, if there is a ping-pong ball at the ball outlet 1, the door body assembly may cause the ping-pong ball to be pinched when it continues to close (the same principle also applies to hand pinching), in order to solve this problem, the application proposes the following design concept:

[0038] The transmission device 73 takes a motor, a gear and a rack as an example, when the anti-pinch door 3 touches the ball body during the closing process, the anti-pinch door 3 will slide relative to the linkage door 2 due to the action force of the ball body, since the spring rod 5 is arranged between the anti-pinch door 3 and the linkage door 2, and the positioning rod 21 is arranged on the linkage door 2, and the movable hole 22 is arranged on the anti-pinch door 3, so when the anti-pinch door 3 is subjected to an external force, the movable hole 22 on the anti-pinch door 3 will move away from the ball body along the positioning rod 21, when the anti-pinch door 3 touches the travel switch 4, the travel switch 4 transmits an electrical signal to the motor, the motor drives the gear to rotate, and drives the linkage door 2 to move to open the ball outlet 1 through the cooperation of the gear and the rack, when the opening door detection sheet metal piece 711 on the linkage door 2 moves to the lower side of the opening door detector 71, the opening door detector 71 feeds back a signal to the motor at this time, the motor reverses to drive the linkage door 2 to move in the opposite direction, when the closing door detection sheet metal piece 721 on the linkage door 2 moves to the lower side of the closing door detector 72, the motor stops rotating, and then the linkage door 2 and the anti-pinch door 3 close the ball outlet 1.

[0039] It should be noted that when the anti-pinch door 3 is subjected to the force of the ball, the anti-pinch door 3 will slide relative to the linkage door 2 to touch the travel switch 4, at this time the spring rod 5 is in a compressed state; but when the ball falls to the game bin 1-2 after leaving the ball outlet 1, at this time the force of the ball on the anti-pinch door 3 disappears, that is, the spring rod 5 will restore the deformation to make the anti-pinch door 3 restore to the original relative position with the linkage door 2, so the anti-pinch door 3 and the linkage door 2 together can close the ball outlet 1.

[0040] On the basis of the above technical scheme, in order to prevent the anti-pinch door 3 from being too large to damage the travel switch 4. The travel switch 4 of the present application is fixed on the linkage door 2 through the mounting seat 6, and the abutting portion 61 is arranged on the mounting seat 6, that is, when the anti-pinch door 3 moves relative to the linkage door 2, the anti-pinch door 3 will first touch the abutting portion 61, and the abutting portion 61 has a buffering effect on the force of the anti-pinch door 3, and then the anti-pinch door 3 will touch the travel switch 4. On this basis, in order to make the anti-pinch door 3 accurately touch the travel switch 4, the present application is provided with a limiting plate 62 on the mounting seat 6, and the limiting plate 62 and the linkage door 2 surround to form a travel channel, which has a guiding effect on the movement track of the anti-pinch door 3.

[0041] On the basis of the above technical scheme, regarding the sliding cooperation of the linkage door 2 and the anti-pinch door 3 at the ball outlet 1, a sliding rail 8 can be arranged on the edge of the ball outlet 1 for the sliding of the linkage door 2 and the anti-pinch door 3.

[0042] In order to prevent the ball and the hand from being pinched, the anti-pinch door 3 is arranged on the linkage door 2 to slide, and the anti-pinch door 3 will slide relative to the linkage door 2 to touch the travel switch 4 when subjected to the action of foreign matter, the travel switch 4 feeds back a signal to the control device, the control device controls the movement of the linkage door 2 and the anti-pinch door 3, so that the foreign matter can smoothly leave the ball outlet 1, effectively achieving the effect of anti-pinch.

[0043] Although the present application has been described in detail with reference to the above examples, it is obvious to those skilled in the art through the disclosure that various changes or modifications can be made to the present application without departing from the principles and spirit of the application defined in the claims. Therefore, the detailed description of the embodiments of the present application is only used to explain, not to limit the present application, and the protection scope is defined by the content of the claims.
