Description

Technical Field

[0001] This utility model relates to the field of gaming devices, and more particularly to a unidirectional lifting mechanism and a multi-round coin-dispensing device. Background Technology

[0002] In related technologies, when lifting a stressed component, the lifting mechanism must stably support it from below, with both components vertically aligned, in order to apply an upward supporting force. However, when the lifting mechanism is initially positioned above the stressed component, it cannot directly apply an upward supporting force. In this case, it is necessary to drive either the stressed component or the lifting mechanism to move horizontally, causing them to shift horizontally, and then reset the lifting mechanism to directly beneath the stressed component. This process increases the complexity of the lifting mechanism's movement. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide a unidirectional lifting mechanism that reduces the series of complex operation steps required when the initial position of the unidirectional lifting mechanism is above the support, such as horizontal movement, staggering and resetting. This simplifies the lifting process and saves lifting time.

[0004] This utility model provides a one-way lifting mechanism, which can be controlled to move in a vertical direction perpendicular to the ground and includes a support and a lifting member; the support has a first locking part; the lifting member is connected to the support via a pivot shaft, which is horizontally arranged; when the lifting member swings downward, it abuts against the first locking part to stop the swinging, and the lifting member is used to provide a vertically upward support force to the load-bearing support, so that the one-way lifting mechanism is used to lift the load-bearing support when it moves upward.

[0005] In some embodiments, the lifting member includes a rotation limiting part and a lifting body, both of which protrude radially from the pivot axis; when the lifting member swings downward, the rotation limiting part abuts against the first locking part to stop the swing, and the lifting body is used to provide a vertically upward support force to the force-bearing support; the lifting body and the rotation limiting part are connected to form a reset structure, which has a downward swinging tendency under the action of gravity.

[0006] In some embodiments, the top of the bracket is provided with a second locking portion, which is used to abut against the lifting member to prevent the center of gravity of the reset structure from passing vertically above the pivot axis.

[0007] In some embodiments, the rotation limiting part has a mating surface that abuts against the first locking part, and the lifting body has a lifting surface that abuts against the second locking part; the mating surface and the lifting surface are spaced 90° apart in the circumferential direction of the reset structure; when the rotation limiting part abuts against the first locking part, the mating surface is parallel to the vertical direction; when the lifting body abuts against the second locking part, the lifting surface is parallel to the vertical direction.

[0008] This utility model also provides a multi-round coin-dispensing device, which includes a lottery mechanism, several coin-dispensing modules, a rotating support module, and a position sensing module. The lottery mechanism includes a linear drive assembly and a one-way lifting mechanism. Each coin-dispensing module includes a coin-loading cylinder, a cover, and a force-receiving support. The force-receiving support is fixedly connected to the coin-loading cylinder, and a coin-dispensing opening is provided at the bottom of the coin-loading cylinder. The cover is detachably located below the coin-dispensing opening. The rotating support module is located below the coin-dispensing module and is used to drive the coin-dispensing module to rotate around the lottery mechanism. The position sensing device is used to detect the position of the coin-dispensing module. The linear drive assembly is configured to drive the one-way lifting mechanism to move upward and lift the force-receiving support when one of the coin-dispensing modules corresponds to the position of the lottery mechanism, thereby separating the coin-dispensing opening of the coin-loading cylinder from the cover.

[0009] In some embodiments, the multi-round coin-dispensing device further includes a central rod, a conductive brush holder, and a conductive slip ring, which are located at the center of the rotating support module and fixedly connected above the lottery mechanism. A central support is fixed to the top of the central rod, and a functional component is mounted on the central support. The conductive brush holder is mounted in the middle of the central support and is electrically connected to the functional component. The conductive slip ring is rotatably mounted on the central rod and is used to electrically couple the conductive brush holder.

[0010] In some embodiments, the linear drive assembly includes a drive device and a transmission device; the transmission device includes a gear and a transmission plate, the transmission plate is provided with a bracket mounting structure for mounting the bracket, and a rack extending vertically is also provided on the side of the transmission plate; the gear is used to be sleeved on the output shaft of the drive device and to mesh with the rack.

[0011] In some embodiments, the lottery mechanism further includes a fixed frame, on which the transmission plate is movably mounted; a first baffle and a second baffle are coupled to the fixed frame, which are spaced apart in the vertical direction; a stop block is fixedly connected to the side of the transmission plate away from the rack; the stop block is used to abut against the first baffle or the second baffle, so that the transmission plate is limited between the first baffle and the second baffle.

[0012] In some embodiments, the fixing frame is further provided with a linear slide rail extending along the vertical direction; the transmission plate is further connected with a slider that slides in cooperation with the linear slide rail.

[0013] In some embodiments, the coin dispensing module further includes an elastic reset member for applying an elastic force toward the cap to the coin cylinder.

[0014] As can be seen from the technical solution, the embodiments provided by this utility model have the following advantages:

[0015] (1) When the lifting member swings downward, it abuts against the first locking part to stop the swinging. The lifting member can provide a vertically upward support force to the force-bearing support. At the same time, the lifting member is subjected to a vertically downward opposing force. The rotational torque formed by this opposing force on the lifting member will make the lifting member and the first locking part press more tightly together, thereby fixing the lifting member relative to the support. Thus, when the unidirectional lifting mechanism moves upward, the lifting member can be fixed relative to the support and transmit power to the force-bearing support.

[0016] (2) The lifting component can swing upward relative to the bracket, and the lifting component moves away from the first locking part. When the force support is below the lifting component, the force support can push the lifting component upward, which reduces the series of complicated operation steps such as horizontal movement, offsetting and resetting that were originally required when the initial position of the unidirectional lifting mechanism was above the force support, thereby simplifying the lifting process.

[0042] The following is for reference. Figures 1-10 This invention describes a unidirectional lifting mechanism and a multi-wheel coin-dispensing device according to embodiments of the present invention.

[0043] Example 1

[0044] like Figures 1-2 As shown, this embodiment provides a one-way lifting mechanism 100. The one-way lifting mechanism 100 can move controllably in a vertical direction perpendicular to the ground. The one-way lifting mechanism 100 includes a support 1 and a lifting member 2. The support 1 has a first locking part 11. The lifting member 2 is connected to the support 1 via a pivot 3. The pivot 3 is horizontally arranged. When the lifting member 2 swings downward, it abuts against the first locking part 11 to stop the swinging. The lifting member 2 is used to provide a vertically upward support force to the support 53, so that the one-way lifting mechanism 100 is used to lift the support 53 when it moves upward.

[0045] like Figure 3and Figure 4 As shown, the unidirectional lifting mechanism 100 can move controllably in the vertical direction, meaning that both the support 1 and the lifting member 2 can move controllably in the vertical direction. Specifically, the output end of a drive such as a linear drive motor or a hydraulic drive device can be connected to the support 1, thereby driving the support 1 to move vertically. Since the lifting member 2 is pivotally mounted on the support 1, the support 1 drives the lifting member 2 to move vertically during the lifting process. The lifting member 2 can also rotate relative to the support 1 during the vertical movement to adjust its posture to adapt to different working conditions.

[0046] like Figure 6 As shown, the force support 53 here refers to one or more components on the lifting mechanism, which can contact the lifting member 2 and transmit power. For example, the multi-wheel coin dispensing device 1000 includes a coin dispensing module 300, which includes a coin cylinder 51, a cover 52, and a force support 53. The force support 53 is fixedly connected to the coin cylinder 51. A coin dispensing port 511 is provided at the bottom of the coin cylinder 51. The cover 52 is detachably located below the coin dispensing port 511. The lifting surface 231 of the lifting member 2 contacts the force support 53 and applies a vertical support force to it. The one-way lifting mechanism 100 lifts the force support 53, the coin cylinder 51 moves upward and separates from the cover 52, and then the coin cylinder 51 exposes the coin dispensing port 511 located below the coin cylinder 51. The game coins in the coin cylinder 51 flow out from the coin dispensing port 511 under their own gravity.

[0047] The unidirectional lifting mechanism 100 provided in this embodiment has the following advantages:

[0048] (1) When the lifting member 2 swings downward, it abuts against the first locking part 11 to stop the swinging. The lifting member 2 can provide a vertically upward support force to the force-bearing support 53. At the same time, the lifting member 2 is subjected to a vertically downward opposite force. The rotational torque formed by this opposite force on the lifting member 2 will make the lifting member 2 and the first locking part 11 press more tightly together, thereby fixing the lifting member 2 relative to the support 1. Thus, when the one-way lifting mechanism 100 moves upward, the lifting member 2 can be fixed relative to the support 1 and transmit power to the force-bearing support 53.

[0049] (2) The lifting component 2 can swing upward relative to the support 1 (e.g. Figure 2 (The direction pointed to by the dashed arrow in the middle) The lifting member 2 separates from the first locking part 11. When the force support 53 is below the lifting member 2, the force support 53 can push the lifting member 2 upward, reducing the series of complex operation steps such as horizontal movement, offsetting and resetting that were originally required when the initial position of the unidirectional lifting mechanism 100 was above the force support 53, thereby simplifying the lifting process.

[0050] Example 2

[0051] like Figure 2 As shown, the lifting member 2 further includes a rotation limiting part 22 and a lifting body 23. Both the rotation limiting part 22 and the lifting body 23 protrude radially from the pivot shaft 3. When the lifting member 2 swings downward, the rotation limiting part 22 abuts against the first locking part 11 to stop the swing. The lifting body 23 is used to provide a vertically upward support force to the force support 53. The lifting body 23 and the rotation limiting part 22 are connected to form a reset structure. The reset structure moves downward under the action of gravity.

[0052] In a specific example, the lifting member 2 includes a rotating connection portion 21, which is constructed as a cylindrical structure extending axially along the pivot shaft 3. The rotating connection portion 21 is sleeved on the outer periphery of the pivot shaft 3. The lifting body 23 is connected to the cylindrical surface of the rotating connection portion 21, and the rotation limiting portion 22 is connected to the cylindrical surface of the rotating connection portion 21. The rotating connection portion 21, the lifting body 23, and the rotation limiting portion 22 are integrally formed. It can be understood that the lifting member 2 is rotatably connected to the support 1 via the pivot shaft 3. When the rotation limiting portion 22 is separated from the first locking portion 11, the lifting member 2 can swing freely relative to the support 1. The rotating connection part 21 is cylindrical. Since the rotation limiting part 22 and the rotating connection part 21 are protrusions connected to the outer cylindrical surface of the cylinder, the reset structure formed after the two are connected makes the mass distribution of the lifting member 2 relative to the pivot shaft 3 uneven. Therefore, when the rotation limiting part 22 is separated from the first locking part 11, the reset structure applies a rotational torque in one direction to the rotating connection part 21. This rotational torque makes the center of gravity of the reset structure tend to rotate directly downwards towards the pivot shaft 3.

[0053] In this embodiment, by setting a reset structure, the mass distribution of the lifting member 2 relative to the pivot shaft 3 is uneven, and the lifting body 23 can swing downward under the action of gravity, without the need for an additional drive mechanism, thus further simplifying the structure.

[0054] Therefore, the working principle of the lifting component 2 in this embodiment is as follows:

[0055] When the lifting body 23 swings downward, the rotation-limiting part 22 approaches the first locking part 11. When the one-way lifting mechanism 100 is in the condition of lifting the support 53, the rotation-limiting part 22 abuts against the first locking part 11, and the lifting body 23 stops swinging. That is, the first locking part 11 can restrict the downward swing of the lifting body 23, and the lifting body 23 can support the support 53. The lifting body 23 applies a vertically upward supporting force to the support 53. At the same time, the lifting body 23 is subjected to a vertically downward opposing force. The rotational torque formed by this opposing force on the lifting member 2 makes the rotation-limiting part 22 and the first locking part 11 press more tightly together, and the lifting body 23 is fixed relative to the support 1. Thus, when the one-way lifting mechanism 100 moves upward, the lifting member 2 can be fixed relative to the support 1 and transmit power to the support 53.

[0056] In a specific example, the lifting component 2 is connected to the support 1 via a pivot shaft 3 and includes a rotation limiting part 22 and a lifting body 23. The rotation limiting part 22 protrudes radially from the pivot shaft 3, and the lifting body 23 protrudes radially from the pivot shaft 3. The maximum distance between the rotation limiting part 22 and the pivot shaft 3 is L1, and the maximum distance between the lifting body 23 and the pivot shaft 3 is L2, where L2 > L1.

[0057] During installation, the horizontal distance between the support 53 and the pivot 3 should be less than L2 and greater than L1. The maximum radial protrusion of the limiting part 22 is L1, and the maximum radial protrusion of the lifting body 23 is L2, where L2 > L1. Furthermore, the horizontal distance between the support 53 and the pivot 3 should be less than L2 and greater than L1. Therefore, when the lifting body 23 and the support 53 are separated in the horizontal direction, the other parts of the lifting member 2 must also be separated from the support 53 in the horizontal direction.

[0058] It should be further noted that during the installation phase, the distance between the unidirectional lifting mechanism 100 and the load-bearing support 53 should meet the following conditions: the horizontal interval between the load-bearing support 53 and the pivot shaft 3 should be less than L2 and greater than L1.

[0059] The lifting body 23 needs to be supported below the force-bearing support 53 in order to apply a vertically upward supporting force to the force-bearing support 53. However, when the initial position of the one-way lifting mechanism 100 is that the lifting body 23 is above the force-bearing support 53, the one-way lifting mechanism 100 needs to move to a position where the lifting body 23 is supported below the force-bearing support 53. During this process, when the lifting member 2 moves vertically, it passes the force-bearing support 53. The force-bearing support 53 contacts the lifting body 23 and causes the lifting body 23 to swing upward, thereby opening the lifting body 23. The lifting body 23 can then swing to a position that is horizontally offset from the force-bearing support 53. When the lifting body 23 swings downward until the first locking part 11 abuts against the rotation-limiting part 22, the distance between the lifting body 23 and the force-bearing support 53 is less than L2, allowing the lifting body 23 to contact the force-bearing support 53.

[0060] Example 3

[0061] like Figure 2 As shown, the top of the support 1 is further provided with a second locking part 12, which is used to abut against the lifting member 2 to prevent the center of gravity of the reset structure from passing vertically above the pivot shaft 3. By providing the second locking part 12, it is possible to prevent the center of gravity of the reset structure from passing vertically above the pivot shaft 3 when the force support 53 pushes open the lifting body 23. As a result, the reset structure always exerts a downward swinging tendency on the lifting body 23, and the swinging tendency of the lifting body 23 can be controlled more precisely.

[0062] Example 4

[0063] like Figure 2 As shown, further, the rotation limiting part 22 has a mating surface 221 that abuts against the first locking part 11, and the lifting body 23 has a lifting surface 231 that abuts against the second locking part 12; the mating surface 221 and the lifting surface 231 are spaced 90° apart in the circumferential direction of the reset structure; when the rotation limiting part 22 abuts against the first locking part 11, the mating surface 221 is parallel to the vertical direction; when the lifting surface 231 abuts against the second locking part 12, the lifting surface 231 is parallel to the vertical direction. That is to say, the mating surface 221 and the lifting surface 231 are spaced 90° apart in the circumferential direction, and are both parallel to the vertical direction when abutting against the corresponding locking parts, which defines a clear boundary for the swing angle of the reset structure, including the lifting body 23 and the rotation limiting part 22. With pivot axis 3 as the center, when the lifting body 23 swings under the action of various forces, the contact between mating surface 221 and first locking part 11, and lifting surface 231 and second locking part 12, limits the swing range of the lifting body 23 to within 90°, which allows for more precise control of the swing angle of the lifting body 23.

[0064] Example 5

[0065] Combination Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, this embodiment provides a multi-round coin-dispensing device 1000, which includes a lottery mechanism 200, a coin-dispensing module 300, a rotating support module 400, and a position sensing device 9. The lottery mechanism 200 includes a linear drive assembly 4 and a one-way lifting mechanism 100 as described in the above embodiment. The coin-dispensing module 300 includes a coin-loading cylinder 51, a cover 52, and a force-receiving support 53. The force-receiving support 53 is fixedly connected to the coin-loading cylinder 51. A coin-dispensing opening 511 is provided at the bottom of the coin-loading cylinder 51, and the cover 52 is detachably disposed below the coin-dispensing opening 511. The rotating support module 400 is located below the coin-dispensing module 300 and is used to drive the coin-dispensing module 300 to rotate around the lottery mechanism; the position sensing device 9 is used to detect the position of the coin-dispensing module 300; the linear drive device 41 is configured to drive the one-way lifting mechanism 100 to move upward and lift the force support 53 when the positions of the coin-dispensing module 300 and the lottery mechanism 200 correspond, thereby separating the coin-dispensing opening 511 of the coin cylinder 51 from the cover 52.

[0066] Each coin-dispensing module 300 is not equipped with a lottery mechanism 200. Instead, the rotating support module 400 drives one of the coin-dispensing modules 300 to rotate to the position corresponding to the lottery mechanism 200. Then, the lottery mechanism 200 draws the lottery for the coin-dispensing module 300. That is, the force support 53 drives the coin cylinder 51 to rise under the lifting of the one-way lifting mechanism 100, so that the coin-dispensing opening 511 of the coin cylinder 51 separates from the cover 52, and the game coins in the coin cylinder 51 can be dispensed to the user.

[0067] Specifically, the multi-round coin-dispensing device 1000 contains multiple coin-dispensing modules 300, which rotate around the lottery-drawing mechanism under the drive of the rotating support module 400. During rotation, each coin-dispensing module 300 has the opportunity to move to a specific relative position with the lottery-drawing mechanism 200. When a particular coin-dispensing module 300 moves to this specific relative position, it is said that this coin-dispensing module 300 and the lottery-drawing mechanism 200 are "positionally aligned". Once the "positional alignment" state is achieved, the linear drive device 41 will start working, driving the one-way lifting mechanism 100 to move upward, thereby lifting the force support 53, realizing the separation of the coin-dispensing opening 511 of the coin cylinder 51 from the cover 52, so as to carry out the coin-dispensing operation. Therefore, "positional alignment" is a key positional condition for triggering the coin-dispensing action.

[0068] Combination Figure 7 and Figure 9 As shown, in the multi-round coin-dispensing structure, since the rotating support module 400 is used to drive the coin-dispensing module 300 to rotate around the lottery mechanism, when installing and debugging the multi-round coin-dispensing device 1000, when one coin-dispensing module 300 moves to a specific relative position, that is, when the position of the coin-dispensing module 300 corresponds to the position of the lottery mechanism 200, it is only necessary to ensure that the force support 53 of the coin-dispensing module 300 can be lifted by the one-way lifting mechanism 100. This will ensure that when the positions of other coin-dispensing modules 300 correspond to the position of the lottery mechanism 200, the force support 53 of the other coin-dispensing modules 300 can also be lifted by the one-way lifting mechanism 100.

[0069] Specifically, the rotating support module 400 includes a slewing bearing and a rotating drive motor. Several coin-spraying modules 300 are disposed on the outer ring of the slewing bearing, and the lottery mechanism 200 is fixed on the inner ring of the slewing bearing. The rotating drive motor is used to drive the outer ring of the slewing bearing to rotate, and the multiple coin-spraying modules 300 rotate accordingly.

[0070] The coin-dispensing module 300 has a coin-loading cylinder 51 that can hold a certain number of game coins. When a user wins a prize, the game coins from one of the coin-dispensing modules 300 are dispensed into the coin outlet corresponding to the winning user's area. Each coin-dispensing module 300 is used to dispense prizes, and each module 300 can also flexibly change its position as the slewing bearing rotates, enabling it to dispense prizes to users in different positions and flexibly replenish coins. Specifically, after the game coins in one coin-dispensing module 300 are dispensed, if another user wins a prize within a short period of time, the other coin-dispensing modules 300 that still contain game coins can change their positions under the rotation of the slewing bearing to continue dispensing prizes to subsequent winners. Meanwhile, the emptied coin-dispensing modules 300 change their positions under the rotation of the slewing bearing and replenish coins after aligning with the coin replenishment device 631.

[0071] Each coin-dispensing module 300 on the rotating support module 400 can be used as a prize draw target, solving the problem of not being able to conduct multiple rounds of prize draws, avoiding excessively long user waiting times, and optimizing the user experience. Furthermore, the position sensing device 9, in conjunction with the prize-drawing mechanism 200, ensures that each coin-dispensing module 300 aligned with the winning area can accurately deliver the prize to the winning user, guaranteeing the reliability and accuracy of prize output and further enhancing the user experience.

[0072] Combination Figure 6 and Figure 7 As shown, in one embodiment, the coin dispensing module 300 includes a coin cylinder 51, a cover 52, and a support 53. The cover 52 is a ramp with an inclined surface, which guides the game coins flowing out of the coin cylinder 51. Therefore, its installation direction needs to be determined in advance during design. Specifically, during installation, it is only necessary to ensure that the game coins flowing down the inclined surface of the ramp can enter the user area. The coin cylinder 51 has openings at the top and bottom, with the lower opening being the coin dispensing port 511, the cross-section of which is parallel to the inclined surface. In this way, when the coin dispensing port 511 of the coin cylinder 51 contacts the inclined surface, the inclined surface can close the coin dispensing port 511 under the weight of the coin cylinder 51 itself, preventing the game coins in the coin cylinder 51 from flowing out. Conversely, the game coins in the coin cylinder 51 can flow down the inclined surface. Thus, the opening and closing of the coin cylinder 51 is achieved by the up-and-down movement of the coin cylinder 51. Therefore, a fixedly connected force support 53 is provided on the coin cylinder 51 to facilitate the lottery mechanism 200 in lifting or lowering the coin cylinder 51 by contacting the force support 53. Specifically, the lottery mechanism 200 lifts the coin cylinder 51 using the force support 53 to move the coin dispensing opening 511 away from the slope, and lowers the coin cylinder 51 using the force support 53 to seal the coin dispensing opening 511 against the slope. In one embodiment, to ensure that the game coins flowing from the cover 52 do not fall from the sides of the slope but only flow out from the bottom of the slope, partitions can be provided on both sides of the cover 52.

[0073] Example 6

[0074] Combination Figures 6-9 As shown, the multi-round coin-dispensing device 1000 further includes a central rod 6, a conductive brush holder 64, and a conductive slip ring 65; the central rod 6 is located at the center of the rotating support module 400 and is fixedly connected above the lottery mechanism 200. A central bracket 62 is fixed to the top of the central rod 6, and a functional component 63 is mounted on the central bracket 62; the conductive brush holder 64 is mounted in the middle of the central bracket 62 and is electrically connected to the functional component 63; the conductive slip ring 65 is rotatably mounted on the central rod 6 and is used for electrically coupling the conductive brush holder 64 and the coin-dispensing module 300.

[0075] Specifically, the central rod 6 is located at the center of the rotating support module 400 and is fixedly connected above the lottery mechanism 200. The central rod 6 does not rotate and its position is fixed. That is, the rotating support module 400 drives several coin-distributing modules 300 to rotate around the central rod 6. A central support 62 is fixed to the top of the central rod 6, and a functional component 63 is installed on the central support 62. A conductive brush holder 64 is installed in the middle of the central support 62 and is electrically connected to the functional component 63. In other words, the positions of the conductive brush holder 64, the functional component 63, and the central support 62 are fixed. A conductive slip ring 65 is rotatably mounted on the central rod 6 and is used for electrical coupling to the conductive brush holder 64. Therefore, an electrical connection is made between the conductive slip ring 65 and the functional component 63 to transmit electrical signals and supply power.

[0076] By setting the conductive slip ring 65 and the conductive brush holder 64, it is beneficial to simplify the layout of the electrical connection structure, reduce the instability of the electrical connection caused by wire entanglement, and reduce the complexity of the electrical connection structure.

[0077] The functional component 63 here includes a position detector 632 and a coin replenishment device 631. The top of the coin cylinder 51 has a coin replenishment port 512. When the position detector 632 detects that the coin cylinder 51 to be replenished is located below the coin replenishment device 631, the coin replenishment device 631 is used to output game coins to the coin replenishment port 512.

[0078] Example 7

[0079] See Figure 3 and Figure 4 As shown, the linear drive assembly 4 further includes a drive device 41 and a transmission device 42; the transmission device 42 includes a gear 421 and a transmission plate 422, the transmission plate 422 is provided with a bracket mounting structure for mounting bracket 1, and a rack 423 extending vertically is also provided on the side of the transmission plate 422; the gear 421 is used to be sleeved on the output shaft 411 of the drive device 41 and to mesh with the transmission rack 423. The transmission connection between the gear 421 and the rack 423 can improve the stability of the linear transmission, which is beneficial for the unidirectional lifting mechanism 100 to move stably in the vertical direction.

[0080] Example 8

[0081] See Figure 3 and Figure 4As shown, the lottery-drawing mechanism 200 further includes a fixed frame 8, on which the transmission plate 422 is movably mounted. A first baffle 81 and a second baffle 82 are coupled to the fixed frame 8, spaced apart vertically. A stop block 424 is fixedly connected to the side of the transmission plate 422 facing away from the rack 423. The stop block 424 abuts against the first baffle 81 or the second baffle 82, limiting the transmission plate 422 between the first baffle 81 and the second baffle 82. This design limits the movement space of the transmission plate 422, preventing it from swaying arbitrarily or exceeding its expected position during movement, ensuring the stability and accuracy of the transmission plate 422's movement. For example, when the linear drive assembly 4 drives the transmission plate 422, the cooperation of the stop block 424 with the first and second baffles 82 ensures that the transmission plate 422 moves within a predetermined track, avoiding collisions or interference with other components due to excessive movement, thus affecting the normal operation of the entire coin-drawing device.

[0082] See Figure 7 Furthermore, the rotating support structure includes a sleeve 61, which is constructed as a cylindrical structure extending in the vertical direction. The axis of the sleeve 61 coincides with the central rod 6 and can rotate around the central rod 6. Multiple coin-dispensing modules 300 are mounted on the outer cylindrical surface of the sleeve 61 along the circumference of the sleeve 61 via mounting brackets 55. The side wall of the sleeve 61 is also provided with elongated holes 611 corresponding to each of the coin-dispensing modules 300. The force-bearing support 53 extends into the interior of the sleeve 61 through the elongated holes 611.

[0083] See Figure 3 and Figure 4 As shown, the fixed frame 8 is further provided with a linear slide rail 83 extending vertically; the transmission plate 422 is also connected with a slider 425 that slides in cooperation with the linear slide rail 83. Thus, when the linear drive assembly 4 drives the transmission plate 422 to rise or fall, the slider 425 slides smoothly along the linear slide rail 83, so that the transmission plate 422 can move more accurately along the predetermined trajectory.

[0084] See Figure 7 As shown, the coin dispensing module 300 further includes an elastic reset member 54, which applies an elastic force towards the cover 52 to the coin cylinder. The elastic reset member 54 is a linear spring, with one end fixed to the coin cylinder 51 and the other end fixed to the sleeve 61. After the coin dispensing action is completed, the one-way lifting mechanism 100 and the force-bearing support 53 separate, and no longer apply an upward force to the force-bearing support 53. At this time, the elastic force of the elastic reset member 54 comes into play, causing the coin cylinder 51 to quickly return to its initial position, tightly fitted with the cover 52, preparing for the next coin dispensing operation. This automatic reset function helps improve the working efficiency of the coin dispensing device, enabling it to quickly enter the next round of coin dispensing, achieving continuous and stable coin dispensing operations.
