Detailed Description
The present invention will be described in further detail with reference to the following examples:
as shown in fig. 1, in embodiment 1, as shown in fig. 1, fig. 2 and fig. 3, the present invention is a table tennis serving device, wherein a ball passing device is disposed at a ball outlet 4 of the serving device. The ball passing device is arranged on the inner side of the ball outlet 4 of the ball serving device and used for protecting the ball passing device and avoiding damage of the ball passing device caused by external force impact. The ball passing device comprises a blocking part 1 and a resetting part 2, wherein the blocking part 1 is arranged on the inner wall of a ball outlet 4 of the ball serving device and can rotate around a point. When no ball passes through the ball outlet 4, one end part of the blocking part 1 shields the ball outlet 4 of the ball serving device, and one end part of the blocking part 1 shields the counting device 3. The reset part 2 is a magnet respectively arranged on the side walls of the blocking part 1 and the ball outlet 4 of the ball serving device. The blocking part 1 blocks that 4 one end tip of ball outlet is the arc, can reduce the friction to the table tennis, extension blocking part 1 life, and the blocking part 1 other end is rectangle or other suitable shapes, and blocking part 1 adopts the preparation of high rigidity material like polycarbonate. When the ball outlet 4 is provided with a ball to pass through, the table tennis extrudes the blocking part 1, the blocking part 1 is stressed to rotate around one point to the blocking part 1 and does not shield the ball outlet 4 of the ball serving device any more, the counting device is kept away from the other end of the blocking part 1 at the moment, counting is triggered, and two magnets arranged on the side walls of the blocking part 1 and the ball outlet 4 of the ball serving device are contacted with each other. After table tennis passes through, the ball outlet is free of balls, and magnets arranged on the side walls of the blocking part 1 and the ball outlet 4 of the ball serving device mutually push the blocking part 1 to reset to the blocking part 1 to partially shield the ball outlet 4 of the ball serving device.
In the further scheme, blocking portion 1 shelters from fixed being provided with the arc spare on ball mouth 4 one end is on a parallel with the axial plane of blocking portion 1, and arc spare one end is provided with the pivot, and the pivot has run through arc spare, blocking portion 1 after-fixing at ball mouth 4 lateral walls, and arc spare revolutes the pivot motion, and then drives the blocking portion and revolutes the pivot motion. The reset part 2 is a magnet respectively arranged on the arc-shaped part of the blocking part 1 and the side wall of the ball outlet 4 of the ball serving device, and the two magnets are opposite in homopolar. Along with the approaching movement of the arc-shaped piece towards the side wall of the ball outlet 4 of the ball serving device, the two magnets are gradually contacted and one end part of the blocking part 1 close to the counting device shields the counting device 3. In the further scheme, the hole is formed in the side wall of the ball outlet 4 of the ball serving device to accommodate the magnet, the side wall of the ball outlet 4 can be further provided with a groove for accommodating the arc-shaped part and the arc-shaped end part of the blocking part 1, and the shape of the groove is matched with the shapes of the arc-shaped part and the arc-shaped end part of the blocking part 1.
When table tennis passes through ball outlet 4, keep away from service device ball outlet 4 behind the table tennis extrusion of blocking portion 1, the magnet that sets up on blocking portion 1 arc piece is pressed close to together with the magnet of fixing at service device ball outlet 4 lateral walls, and the table tennis passes through service device ball outlet 4 smoothly. After the table tennis passes through the ball outlet 4 of the ball serving device, the magnets arranged on the arc-shaped pieces of the blocking parts 1 repel each other with the same poles of the magnets fixed on the side walls of the ball outlet 4 of the ball serving device, and the blocking parts 1 are reset to the blocking parts 1 by repulsive force to partially shield the ball outlet 4 of the ball serving device. In a further scheme, the blocking part 1 and the side wall of the ball outlet 4 of the ball serving device are provided with a plurality of pairs of magnets, so that the repulsive force is increased, and the number of suitable magnets can be set to meet the operation requirement of the actual ball serving device.
The embodiment 2 is different from the embodiment 1 mainly in that when the counting device 3 is a photoelectric sensor and the counting device 3 is arranged as a photoelectric counting sensor, the blocking part 1 blocks the counting device 3 to judge the passing of the table tennis balls and count the table tennis balls, so that an accurate counting result is obtained. Counting assembly 3 is that photoelectric sensor sets up and keeps away from service device export one end at blocking portion 1, and when blocking portion 1 part sheltered from service device play ball mouth 4, blocking portion 1 kept away from service device export one end and sheltered from counting assembly 3. When table tennis passes through the ball outlet 4, the blocking part 1 is extruded by the table tennis and moves out of the ball outlet 4 of the ball serving device, the blocking part 1 moves away from the counting device 3, the photoelectric sensor triggers to transmit a counting signal to the receiving device for counting, and the table tennis smoothly passes through the ball outlet 4 of the ball serving device. After the table tennis passes through the ball outlet 4 of the ball serving device, the magnets arranged on the arc-shaped pieces of the blocking parts 1 repel each other with the same poles of the magnets fixed on the side walls of the ball outlet 4 of the ball serving device, and the blocking parts 1 are reset to the photoelectric sensors of the counting device 3 by repulsive force to shield the photoelectric sensors.
