DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0035] Referring to Figures 1-6 As shown in the figure, a tamper-proof top ball device with high operation accuracy, comprising a cabinet body 1 with a cabinet door 11, the cabinet body 1 is provided with a ball conveying channel 2 at the top, the cabinet body 1 is internally provided with a ball washing turntable 3, a ball feeding mechanism 4 is arranged between the ball conveying channel 2 and the ball washing turntable 3 to feed one game ball on the ball washing turntable 3 to the ball conveying channel 2 each time, a plurality of support parts 31 capable of bearing game balls are uniformly distributed along the circumferential direction of the ball washing turntable 3, the ball conveying channel 2 is provided with an inlet 32 connected with the ball feeding mechanism 4 and an outlet 33 opposite to one support part 31 on the ball washing turntable 3 each time, the cabinet body 1 is provided with a rotating driver 12 for driving the ball washing turntable 3 to rotate intermittently, one support part 31 on the ball washing turntable 3 corresponds to the outlet 33 each time the ball washing turntable 3 rotates by an angle, the cabinet body 1 is internally provided with a detection assembly 5 for measuring the rotation accuracy of the ball washing turntable 3, the detection assembly 5 is provided with a reflecting part 51 arranged on the ball washing turntable 3 for reflecting signals and a sensing part 52 arranged on the cabinet body 1 for sending and receiving signals, the cabinet body 1 is further internally provided with a locking part 6 connected with the cabinet door 11 for preventing players from opening the cabinet door 11 to tamper with the rotation data of the ball washing turntable 3.

[0036] When the game starts, the locking part 6 in the cabinet body 1 is automatically started to firmly lock the cabinet door 11. Any unauthorized personnel is prevented from opening the cabinet door 11 during the game, thereby avoiding tampering with the rotation data of the ball washing turntable 3. The rotating driver 12 installed on the cabinet body 1 is responsible for controlling the intermittent rotation of the ball washing turntable 3. Whenever the ball washing turntable 3 completes a rotation, one of the support parts 31 will be accurately aligned with the outlet 33 of the ball conveying channel 2, ensuring that the game ball falling from the ball conveying channel 2 accurately falls on the support part 31 of the ball washing turntable 3.

[0037] When the player is ready, the system will prompt the player to select a specific game ball as the target. After selecting the target ball, the player presses the button to indicate the ball washing turntable 3 to stop rotating. Since each support part 31 on the ball washing turntable 3 bears a game ball, after the ball washing turntable 3 completely stops, the ball feeding mechanism 4 will push the game ball located on the current support part 31 into the ball conveying channel 2, entering the next ball guessing link. During the process of feeding the game ball, the player can observe the game ball to confirm whether the selected target ball is guessed. After the game ball enters the inlet 32 of the ball conveying channel 2, it will be accurately guided to the outlet 33. At this time, the ball feeding mechanism 4 will be in a standby state, preparing for the next ball guessing link.

[0038] During the rotation of the ball washing turntable 3, the reflection part 51 will reflect the signal from the induction part 52 every time the ball washing turntable 3 rotates by a certain angle. After receiving the reflected signal, the induction part 52 can immediately calculate the actual position and rotation speed of the ball washing turntable 3. Through real-time monitoring of the data, it can be judged whether the ball washing turntable 3 works normally according to the predetermined angle and time interval. Once any deviation is found, the rotation driver 12 will timely adjust the rotation state of the ball washing turntable 3 to ensure that the game is always running in a high-precision state.

[0039] Referring to Figures 2-4 、 Figure 6 、 Figure 8 and Figure 9 , the reflection part 51 has a first calibration piece 511 arranged at the top of the ball washing turntable 3 and close to the edge thereof, and the induction part 52 has a first sensor 521 arranged on the cabinet 1 and capable of measuring the starting point of the ball washing turntable 3 through the first calibration piece 511.

[0040] When the ball washing turntable 3 starts to rotate, the first calibration piece 511 will rotate with the ball washing turntable 3. When the first calibration piece 511 passes through the first sensor 521, the first sensor 521 accurately measures the starting point of the ball washing turntable 3 by detecting the position of the first calibration piece 511.

[0041] It is ensured that the system can accurately obtain the initial position of each rotation of the ball washing turntable 3, thereby providing a reference for subsequent angle and speed monitoring.

[0042] Referring to Figures 2-4 、 Figure 6 、 Figure 8 and Figure 9 , the reflection part 51 further has a plurality of second calibration pieces 512 arranged at the bottom of the ball washing turntable 3 and close to the edge thereof, one of the second calibration pieces 512 is arranged between every two adjacent support parts 31, and the induction part 52 further has a second sensor 522 arranged on the cabinet 1 and capable of measuring the rotation angle of the ball washing turntable 3 through the second calibration piece 512.

[0043] When the ball washing turntable 3 rotates, all the second calibration pieces 512 will pass through the second sensor 522 in turn. The second sensor 522 accurately measures the angle of each rotation of the ball washing turntable 3 by detecting the position change of the second calibration piece 512.

[0044] It is ensured that the system can obtain the specific rotation angle of the ball washing turntable 3 in real time, further improving the rotation accuracy and the accuracy of ball feeding, and avoiding the phenomenon that the game ball is stuck during the feeding process.

[0045] Referring to Figure 8 and Figure 9As shown, the first calibration member 511 and the second calibration member 512 are both plate-shaped structures, and the side of the first calibration member 511 and the second calibration member 512 that can reflect signals is a vertical side to prevent dust accumulation from interfering with signal reflection.

[0046] Since the side of the first calibration member 511 and the second calibration member 512 that can reflect signals is a vertical side, dust accumulation that interferes with signal reflection can be prevented.

[0047] Compared to a horizontal side that can reflect signals, the first calibration member 511 and the second calibration member 512 significantly reduce dust accumulation on the surface, so that dust is not easily deposited. Thus, the stability and accuracy of signal reflection are ensured, and the detection accuracy and reliability of the ball washing turntable 3 are further improved.

[0048] Referring to Figures 2-7 As shown, the ball feeding mechanism 4 includes a ball lifting assembly 41 arranged below the ball washing turntable 3, a guide pipe 42 arranged above the ball washing turntable 3, and a ball moving assembly 43 arranged between the guide pipe 42 and the ball conveying passage 2. There is a support part 31 corresponding to the ball lifting assembly 41 and the guide pipe 42 for each rotation angle of the ball washing turntable 3, forming a three-point coaxial movement path for the game balls to be lifted from the support part 31 to the guide pipe 42.

[0049] The ball lifting assembly 41 has a lifting rod 411 coaxial with the guide pipe 42 and a lifting driver 412 for driving the lifting rod 411 to lift and lower.

[0050] The ball moving assembly 43 has a guide rail 431 connected between the guide pipe 42 and the ball conveying passage 2, and a sliding sleeve 432 for moving the game balls lifted to the top of the guide pipe 42 along the guide rail 431. The sliding sleeve 432 has a sleeve opening for the game balls to be embedded from bottom to top. The cabinet 1 is provided with a linear driver 433 for driving the sliding sleeve 432 to move along the guide rail 431.

[0051] The guide rail 431 and the inlet 32 of the ball conveying passage 2 are further provided with a turnover plate 321 that turns from the guide rail 431 to the ball conveying passage 2. The cabinet 1 is provided with a turnover driver 322 for driving the turnover plate 321 to rotate. The turnover plate 321 is provided with a circular opening for supporting the game balls. When the game balls are moved by the sliding sleeve 432 to the turnover plate 321, the game balls fall from the sliding sleeve 432 to the circular opening on the turnover plate 321. With the sliding sleeve 432 returning to its original position, the turnover driver 322 drives the turnover plate 321 to rotate, so that the game balls enter the ball conveying passage 2.

[0052] Specifically, when the ball washing turntable 3 rotates by one angle, each support part 31 corresponding to the ball pushing assembly 41 and the guide pipe 42 forms a three-point coaxial movement path, so that the game ball can be lifted from the support part 31 into the guide pipe 42. The lifting rod 411 in the ball pushing assembly 41 is coaxial with the guide pipe 42 and is driven by the lifting driver 412 to perform a lifting action to lift the game ball.

[0053] At the same time, the linear driver 433 drives the sliding sleeve 432 to move along the guide rail 431, so that the game ball moves along the guide rail 431 from the top of the guide pipe 42 to the turnover plate 321.

[0054] When the game ball reaches the turnover plate 321, the game ball falls from the sliding sleeve 432 into the round hole on the turnover plate 321, at which time the player can clearly see the game ball and know whether the selection is correct. Subsequently, the sliding sleeve 432 returns to the original position, the turnover driver 322 drives the turnover plate 321 to rotate, and finally the game ball is sent into the ball conveying channel 2 and returns to the ball washing turntable 3.

[0055] Referring to Figures 2-4 , Figure 6 , Figure 8 and Figure 9 , the support part 31 is specifically a groove opened on the ball washing turntable 3 and capable of fitting the game ball. The bottom of the groove is an opening structure capable of lifting the game ball into the guide pipe 42 by the ball pushing assembly 41.

[0056] When the ball washing turntable 3 rotates, the game ball is located in the groove opened on the turntable, the groove fits the shape of the game ball, and the stability is ensured.

[0057] When the lifting rod 411 of the ball pushing assembly 41 is lifted by the lifting driver 412, the game ball can be smoothly lifted from the groove through the opening of the groove until the game ball enters the guide pipe 42 above. The accurate positioning and smooth transition of the game ball during the lifting process are ensured.

[0058] Referring to Figures 1-6 and Figure 10 , the locking member 6 is specifically an electronic lock, and the cabinet door 11 is provided with a control panel 61 for opening the electronic lock through a program.

[0059] When the authorized personnel needs to open the cabinet door 11, the control panel 61 receives the opening instruction through the preset program and sends the unlocking signal to the electronic lock. After receiving the signal, the electronic lock performs the unlocking action, so that the cabinet door 11 can be smoothly opened.

[0060] Compared with the traditional mechanical unlocking mode, the possibility of the player opening the cabinet door 11 is avoided. At the same time, the automation and intelligent management of the cabinet door 11 opening are realized. The opening of the cabinet door 11 is strictly controlled by the program, and the security and automation level are improved.

[0061] Referring to Figures 1-4 As shown, the top of the cabinet body 1 is provided with a glass cover 7 in which the ball passing channel 2 and the feeding mechanism cover are arranged.

[0062] The glass cover 7 effectively isolates the influence of the external environment on the game ball, prevents dust and foreign matter from entering, and ensures the stable operation of the ball feeding mechanism 4. At the same time, the transparent glass cover 7 provides good visibility, and the player can clearly observe the transfer of the game ball, ensuring that the player can know whether he has made the right choice.

[0063] The utility model discloses a rotation process of the ball washing turntable 3 is monitored in real time through the cooperation of the reflection part 51 and the induction part 52, the accuracy of the ball feeding mechanism 4 is improved, and the game ball jamming condition is avoided.

[0064] In order to ensure the fairness of the game, the cabinet door 11 is fixed by the locking member 6. After the control panel 61 receives the opening instruction, the unlocking signal is sent to the electronic lock, so that the cabinet door 11 is only authorized to open, and unauthorized operation is prevented. Prevent unauthorized personnel from tampering with the ball feeding data, further protect the fairness and safety of the game.

[0065] The above embodiments only express one or several embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the protection scope of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the appended claims.
