Description

Technical Field

[0001] This utility model relates to the field of financial equipment technology, and in particular to a gate mechanism and a banknote collection device. Background Technology

[0002] Existing banknote collection devices typically include a frame and a gate mechanism. The frame has a receiving cavity for holding banknotes, with an outlet. The gate mechanism includes a gate and a motor. The gate is movably connected to the frame and has an open position (open outlet) and a closed position (closed outlet). When the gate is in the open position, banknotes can be retrieved from the receiving cavity through the outlet. The motor is driven by the gate to move it to the open and closed positions. With this type of gate mechanism, if an external force forcibly drives the gate to the open position when it is in the closed position, the gate can be pried open, thus resulting in low security. To address this, a gate mechanism with a self-locking function has been provided. This mechanism includes a self-locking component comprising an electromagnet and a locking hook. The electromagnet is kinetically connected to the locking hook and drives the locking hook to a locked position and an unlocked position. When the locking hook is in the locked position, it engages with the gate in the closed position, preventing the gate from moving to the open position. When the locking hook is in the unlocked position, it disengages from the gate, allowing the gate to move to the open position under the drive of a motor. However, this gate mechanism includes both a motor for driving the gate and an electromagnet for driving the locking hook, increasing the manufacturing cost. Therefore, a gate mechanism with high safety and low cost is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide a gate mechanism and a banknote collection device to reduce the manufacturing cost of the gate mechanism while ensuring its safety.

[0004] On the one hand, this utility model provides a gate mechanism, which includes:

[0005] frame;

[0006] A gate is movably connected to the frame, and the gate is movable relative to the frame to have an open position and a closed position;

[0007] A locking assembly includes a stop and a resilient element. The stop is movably connected to the frame and is movable relative to the frame to have a locked position and an unlocked position. When the gate is in the closed position and the stop is in the locked position, the stop extends into the path of the gate moving from the closed position to the open position to prevent the gate from moving to the open position. When the stop is in the unlocked position, the stop retracts from the path of the gate moving from the closed position to the open position to allow the gate to move to the open position. During the movement of the gate to the open position, the gate always prevents the stop from extending into the path of the gate moving from the closed position to the open position. The resilient element is connected between the stop and the frame, and the elastic force of the resilient element is configured to give the stop a tendency to always move to the locked position.

[0008] A first transmission assembly includes a transmission shaft and a transmission component. The transmission shaft is rotatably mounted on the frame and is drively connected to the gate. The transmission shaft drives the gate to the open position. The transmission component is rotatably sleeved on the transmission shaft. When the transmission component rotates, it can drive the stop to the unlock position. When the gate is in the closed position and the stop is in the locked position, the transmission component is configured to disconnect the transmission connection with the transmission shaft during the process of driving the stop to the unlock position. After the transmission component drives the stop to the unlock position, it is drively connected to the transmission shaft so that the transmission component can drive the gate to the open position through the transmission shaft.

[0009] An electric motor is connected to the transmission component, and the electric motor is used to drive the transmission component to rotate.

[0010] As a preferred technical solution for the gate mechanism, the transmission component includes a transmission gear, a groove, and a pin. The transmission gear is connected to the motor. The groove is formed in one of the transmission shaft and the transmission gear. The groove has a first end and a second end that are spaced apart along the circumferential direction of the transmission gear. The pin is connected to the other of the transmission shaft and the transmission gear, and the pin is located in the groove.

[0011] When the gate is in the closed position and the stop is in the locked position, during the process of the transmission member driving the stop to move to the unlocked position, the pin moves from the first end to the second end relative to the groove, and the transmission gear separates from the pin, so that the transmission member disconnects from the transmission shaft. After the transmission member drives the stop to move to the unlocked position, the pin abuts against the second end of the groove, so that the transmission member is connected to the transmission shaft, and the rotating transmission gear can drive the transmission shaft to rotate synchronously in the same direction.

[0012] As a preferred technical solution for the gate mechanism, the transmission component further includes a pressing part fixedly connected to the end face of the transmission gear. During the rotation of the transmission gear, the pressing part can abut against the stop and drive the stop to move to the unlock position.

[0013] As a preferred technical solution for the gate mechanism, the transmission component further includes a limiting post. The transmission gear, the pressing part, and the limiting post are coaxial and fixedly connected in sequence. The outer diameters of the transmission gear and the limiting post are both larger than the outer diameter of the pressing part. When the pressing part abuts against the stop member, the stop member is located between the transmission gear and the limiting post.

[0014] As a preferred technical solution for the gate mechanism, the gate mechanism further includes a second transmission assembly. The transmission shaft is connected to the gate via the second transmission assembly. The second transmission assembly includes a first transition gear, a portal gear, and a rack. The first transition gear is fixedly sleeved on the transmission shaft. The portal gear is directly or intermittently meshed with the first transition gear. The rack is fixedly connected to the gate and extends along the direction of movement of the gate. The rack also meshes with the portal gear.

[0015] As a preferred technical solution for the gate mechanism, the frame includes an outer support, and the elastic force of the elastic element causes the stop to always have a rotational tendency to move closer to the outer support;

[0016] When the gate is in the open position, the gate retracts between the stop and the outer support; when the gate is in the closed position, the gate extends out from between the stop and the outer support.

[0017] As a preferred technical solution for the gate mechanism, the frame further includes an inner support fixedly connected to the outer support, the inner support including a support shaft and a transition shaft arranged parallel to and spaced apart from the transmission shaft; the locking assembly includes two stops, both stops being rotatably sleeved on the support shaft, and both stops being able to rotate around the support shaft to the locked position and the unlocked position;

[0018] The first transmission assembly includes two transmission members, both of which are sleeved on the transmission shaft, and the two transmission members are correspondingly arranged with the two stop members; the gate mechanism further includes a third transmission assembly, which includes two second transition gears, both of which are fixedly sleeved on the transition shaft, and the two second transition gears are connected to the transmission gears of the two transmission members in a corresponding transmission connection, and one of the two second transition gears is connected to the motor.

[0019] As a preferred technical solution for the gate mechanism, the outer support includes a first wall and a second wall that are spaced apart from each other, and a third wall connected between the first wall and the second wall. The first wall is provided with a first guide groove, the second wall is provided with a second guide groove, and the third wall is provided with a rotatable limiting wheel.

[0020] The gate is located between the first wall and the second wall. The gate includes a first guide end opposite to the first wall and a second guide end opposite to the second wall. The first guide end is provided with at least two rotatable first guide wheels, and at least two first guide wheels are inserted into the first guide groove. The second guide end is provided with at least two rotatable second guide wheels, and at least two second guide wheels are inserted into the second guide groove. When the gate moves between the open position and the closed position, the first guide wheels roll along the first guide groove, the second guide wheels roll along the second guide groove, and the limiting wheel rolls along the outer surface of the gate.

[0021] As a preferred technical solution for the gate mechanism, the inner surface of the gate is provided with a retaining strip. The retaining strip includes a guide surface extending along the movement direction of the gate and a blocking surface perpendicular to the guide surface. The blocking surface is located at the end of the guide surface along the opening direction of the gate.

[0022] When the gate is in the closed position and the stop is in the locked position, the stop is located downstream of and opposite to the blocking surface in the opening direction of the gate, so as to prevent the gate from moving to the open position; when the transmission member drives the stop to the unlocked position, the stop separates from the locking strip; when the gate moves from the closed position to the open position and from the open position to the closed position, the stop can abut against the guide surface under the elastic force of the elastic member, and during the process of the gate moving to the closed position or the open position, the guide surface always prevents the stop from extending into the path of the gate moving from the closed position to the open position.

[0023] The gate mechanism provided by this utility model has at least the following beneficial effects:

[0024] The gate mechanism includes a frame, a gate, a locking assembly, a first transmission assembly, and a motor. The gate is movably connected to the frame and can move relative to the frame to have an open position and a closed position. The locking assembly includes a stop and a resilient member. The stop is movably connected to the frame and can move relative to the frame to have a locked position and an unlocked position. When the gate is in the closed position and the stop is in the locked position, the stop extends into the path of the gate moving from the closed position to the open position to prevent the gate from moving to the open position. When the stop is in the unlocked position and the stop is in the locked position, the stop retracts from the path of the gate moving from the closed position to the open position, allowing the gate to move to the open position. During the movement of the gate to the open position, the gate always prevents the stop from extending into the path of the gate moving from the closed position to the open position. Along the movement path, an elastic element connects the stop and the frame. The elastic force of the elastic element is configured to ensure that the stop always tends to move towards the locked position. The first transmission assembly includes a transmission shaft and a transmission component. The transmission shaft is rotatably mounted on the frame and is driven by the gate. The transmission shaft drives the gate to the open position. The transmission component is rotatably sleeved on the transmission shaft. When the transmission component rotates, it drives the stop to the unlocked position. When the gate is in the closed position, the transmission component is configured to disconnect from the transmission shaft during the process of driving the stop to the unlocked position. After the transmission component drives the stop to the unlocked position, it is driven back to the transmission shaft, so that the transmission component can drive the gate to the open position via the transmission shaft. A motor is driven by the transmission component and drives the transmission component to rotate. The gate mechanism provided in this embodiment uses the same motor to both drive the stop to the unlocked position and drive the gate to move, thus reducing the cost of the gate mechanism while ensuring its safety.

[0025] Secondly, this utility model also provides a banknote accumulation device, which includes a receiving cavity for storing banknotes and a gate mechanism as described in any of the above embodiments. The receiving cavity has an outlet. When the gate is in the closed position, the outlet is closed by the gate, and when the gate is in the open position, the outlet is opened.

[0026] The banknote accumulation device provided by this utility model has at least the following beneficial effects:

[0027] The banknote collection device employs the aforementioned gate mechanism, which ensures high security while also reducing manufacturing costs. Attached Figure Description

[0052] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0053] Please refer to Figures 1 to 3This embodiment provides a gate mechanism, which includes a frame 1, a gate 2, a locking component 3, a first transmission component 4, and a motor 5. The gate 2 is movably connected to the frame 1, and can move relative to the frame 1 to have an open position and a closed position. The locking assembly 3 includes a stop 31 and an elastic member 32. The stop 31 is movably connected to the frame 1 and can move relative to the frame 1 to have a locked position and an unlocked position. When the gate 2 is in the closed position and the stop 31 is in the locked position, the stop 31 extends into the path of the gate 2 moving from the closed position to the open position to prevent the gate 2 from moving to the open position. When the stop 31 is in the unlocked position, the stop 31 exits the path of the gate 2 moving from the closed position to the open position so that the gate 2 can move to the open position. During the process of the gate 2 moving to the open position, the gate 2 always prevents the stop 31 from extending into the path of the gate 2 moving from the closed position to the open position. The elastic member 32 is connected between the stop 31 and the frame 1. The elastic member 32 has a spring-like elasticity. The force is configured to ensure that the stop 31 always tends to move towards the locked position; the first transmission assembly 4 includes a transmission shaft 41 and a transmission member 42. The transmission shaft 41 is rotatably mounted on the frame 1 and is connected to the gate 2. The transmission shaft 41 is used to drive the gate 2 to the open position. The transmission member 42 is rotatably sleeved on the transmission shaft 41. When the transmission member 42 rotates, it can drive the stop 31 to the unlocked position. When the gate 2 is in the closed position and the stop 31 is in the locked position, the transmission member 42 is configured to disconnect the transmission connection with the transmission shaft 41 during the process of driving the stop 31 to the unlocked position. After the transmission member 42 drives the stop 31 to the unlocked position, it is connected to the transmission shaft 41 so that the transmission member 42 can drive the gate 2 to the open position through the transmission shaft 41; the motor 5 is connected to the transmission member 42 and is used to drive the transmission member 42 to rotate. In this embodiment, the elastic member 32 is a tension spring. In other embodiments, the elastic member 32 can also be a torsion spring, compression spring, etc.

[0054] In this embodiment, when the gate 2 is in the closed position, the stop 31 moves to the locked position under the elastic force of the elastic member 32. The stop 31 extends into the path of the gate 2 moving from the closed position to the open position to prevent the gate 2 from moving to the open position, thereby stably locking the gate 2 in the closed position and preventing the gate 2 from being opened under external force, ensuring the safety of the gate mechanism. When the gate 2 is to be opened, the motor 5 drives the transmission member 42 to rotate. The rotating transmission member 42 drives the stop 31 to the unlocked position. During this process, there is no transmission connection between the transmission shaft 41 and the transmission member 42. Therefore, the rotation of the transmission member 42 will not drive the transmission shaft 41 to rotate, and the transmission shaft 41 will not affect the gate 2, so that the gate 2 remains in the closed position. When the stop 31 moves to the unlocked position, the transmission member 42 is connected to the transmission shaft 41. When the transmission member 42 continues to rotate, it can drive the transmission shaft 41 to rotate synchronously and in the same direction, thereby enabling the transmission shaft 41 to drive the gate 2 to move to the open position. The gate mechanism provided in this embodiment uses the same motor 5 to drive the stop 31 to move to unlock the gate 2 and to drive the gate 2 to move to the open position. Therefore, while ensuring the safety of the gate mechanism, the cost of the gate mechanism is also reduced.

[0055] Alternatively, please refer to Figures 4 to 6The transmission component 42 includes a transmission gear 421, a groove 422, and a pin 425. The transmission gear 421 is connected to the motor 5. The groove 422 is formed in one of the transmission shaft 41 and the transmission gear 421. The groove 422 has a first end 423 and a second end 424 spaced apart along the circumference of the transmission gear 421. The pin 425 is connected to the other of the transmission shaft 41 and the transmission gear 421, and the pin 425 is located within the groove 422. When the gate 2 is in the closed position and the stop 31 is in the locked position, During the process of the transmission component 42 driving the stop component 31 to the unlock position, the pin 425 moves from the first end 423 to the second end 424 relative to the groove 422, and the transmission gear 421 separates from the pin 425, so that the transmission component 42 disconnects the transmission connection with the transmission shaft 41; after the transmission component 42 drives the stop component 31 to the unlock position, the pin 425 abuts against the second end 424 of the groove 422, so that the transmission component 42 is connected to the transmission shaft 41, and the rotating transmission gear 421 can drive the transmission shaft 41 to rotate synchronously and in the same direction. In this embodiment, an exemplary scheme is provided where the groove 422 is disposed on the transmission gear 421 and the pin 425 is connected to the transmission shaft 41. By utilizing the insertion and engagement of the pin 425 with the groove 422, and the fact that the pin 425 has a certain angle of free travel relative to the groove 422, the transmission connection between the pin 425 and the transmission shaft 41 can be broken during the process of the transmission member 42 driving the stop member 31 to the unlocked position. Furthermore, the pin 425 can also abut against the first end 423 or the second end 424 of the groove 422, enabling a transmission connection between the pin 425 and the transmission shaft 41 after the transmission member 42 has driven the stop member 31 to the unlocked position. In other embodiments, the groove 422 can also be disposed on the transmission shaft 41, and the pin 425 can be connected to the transmission gear 421.

[0056] Specifically, in this embodiment, when the gate 2 is in the closed position and the stop 31 is in the locked position, when it is necessary to open the gate 2, the output shaft 52 of the motor 5 is in the positive direction (e.g., Figure 5(In the direction indicated by the arrow oa) the motor 5 drives the transmission component 42 to rotate in the forward direction. Initially, the pin 425 is close to the first end of the groove 422. After the transmission component 42 rotates, the pin 425 moves from the first end 423 to the second end 424 of the groove 422. The pin 425 does not contact the first end 423 and the second end 424 of the groove 422. The movement of one of the pin 425 and the groove 422 will not be transmitted to the other, so that the transmission connection between the transmission component 42 and the transmission shaft 41 is broken, and the rotation of the transmission component 42 will not be transmitted to the transmission shaft 41. After the transmission component 42 drives the stop 31 to move to the unlocked position, the pin 425 abuts against the second end 424 of the groove 422. Then, the continued rotation of the pin 425 and the groove 422 can drive the other to rotate synchronously in the same direction, so that the transmission connection between the transmission component 42 and the transmission shaft 41 is established. The rotation of the transmission component 42 can be transmitted to the transmission shaft 41, and the rotation of the transmission shaft 41 drives the gate 2 to move to the open position. When the gate moves from the closed position to the open position, the stop 31 prevents the gate 2 from extending into the path of the gate 2 moving from the closed position to the open position. In other words, the stop 31 will not affect the movement of the gate 2, so that the gate 2 can open smoothly. When gate 2 is in the open position, when it needs to be closed, the output shaft 52 of motor 5 rotates in the reverse direction, driving the transmission component 42 to rotate in the reverse direction. The pin 425 moves from the second end 424 to the first end 423 relative to the groove 422, and the transmission connection between the transmission component 42 and the transmission shaft 41 is broken. At this time, there are two scenarios for the movement between the transmission component 42 and the stop 31. One scenario is that the transmission component 42 and the stop 31 separate, and the stop 31 abuts against the inner surface of gate 2 under the action of the elastic member 32. Gate 2 prevents the stop 31 from extending into the path of the gate 2 moving from the closed position to the open position. Therefore, the stop 31 will not affect the movement of gate 2. The other scenario is that the transmission component 42 drives the stop 31 to move to the unlocked position, and the stop 31 in the unlocked position... The moving part 31 will not affect the movement of the gate 2. When the pin 425 abuts against the first end 423 of the groove 422, the transmission part 42 is connected to the transmission shaft 41. As the transmission part 42 continues to rotate in the opposite direction, the transmission part 42 drives the transmission shaft 41 to rotate in the opposite direction. The transmission shaft 41 drives the gate 2 to move towards the closed position. During this process, the movement between the transmission part 42 and the stop part 31 is the same as the movement between the transmission part 42 and the stop part 31 during the closing process. Therefore, the stop part 31 will not affect the movement of the gate 2, and the gate 2 can close smoothly. When the gate 2 moves to the closed position, the transmission part 42 and the stop part 31 separate. Under the action of the elastic force of the elastic part 32, the stop part 31 extends into the path of the gate 2 moving from the closed position to the open position to lock the position of the gate 2.

[0057] It should be noted that during the movement of gate 2 from the closed position to the open position, the number of rotations of the transmission gear 421 can be set according to actual needs. During one rotation of the transmission gear 421, the transmission component 42 periodically drives the stop 31 to the unlocked position and periodically separates from it. As gate 2 moves from the closed position to the open position, the continuous rotation of the transmission gear 421 causes the movement of the stop 31 to change periodically. Specifically, when the stop 31 is driven to the unlocked position by the transmission component 42... When the gate 2 can move smoothly, when the transmission member 42 separates from the stop member 31, under the action of the elastic member 32, the stop member 31 abuts against the gate 2, and the gate 2 can prevent the stop member 31 from moving to the locked position, which will not hinder the movement of the gate 2. In addition, when the gate 2 moves to the open position, since the current angle of the transmission gear 421 cannot be determined, the transmission member 42 may separate from the stop member 31 at this time, and the stop member 31 may abut against the inner surface of the gate 2 under the action of the elastic member 32; or the transmission member 42 may drive the stop member 31 to the unlocked position.

[0058] Alternatively, please refer to Figure 5 In this embodiment, the transmission component 42 includes two grooves 422, both of which are formed on the transmission gear 421. The two grooves 422 are symmetrically arranged about the axis of the transmission gear 421. The two ends of the pin 425 extend out of the transmission shaft 41 and are respectively inserted into the two grooves 422. With this arrangement, when the two ends of the pin 425 abut against the second ends 424 of the two grooves 422 and drive the transmission shaft 41 to rotate, the power of the transmission component 42 can be transmitted to the transmission shaft 41 more stably and reliably.

[0059] As one alternative, please refer to Figure 7The transmission component 42 includes a transmission gear 421, a protrusion 426, and a groove 422. The transmission gear 421 is connected to the motor 5. One of the protrusion 426 and the groove 422 is located on the end face of the transmission gear 421, and the other of the protrusion 426 and the groove 422 is located on the end face of the transmission shaft 41. Along the circumferential direction of the transmission gear 421, the size of the groove 422 is larger than the size of the protrusion 426. The groove 422 has a first end 423 and a second end 424. The protrusion 426 is inserted into the groove 422. When the gate 2 is in the closed position... When the stop 31 is in the locked position and the transmission member 42 drives the stop 31 to the unlocked position, the protrusion 426 moves from the first end 423 to the second end 424 relative to the groove 422, and the transmission connection between the transmission member 42 and the transmission shaft 41 is broken. When the transmission member 42 drives the stop 31 to the unlocked position, the protrusion 426 abuts against the second end 424 of the groove 422, and the rotating transmission member 42 can drive the transmission shaft 41 to rotate synchronously and in the same direction, so that the transmission connection between the transmission member 42 and the transmission shaft 41 is maintained.

[0060] Alternatively, please refer to Figure 4 and Figure 7 The transmission member 42 also includes a pressing part 427 fixedly connected to the end face of the transmission gear 421. During the rotation of the transmission gear 421, the pressing part 427 can abut against the stop member 31 and drive the stop member 31 to move to the unlock position. With this configuration, when the transmission gear 421 rotates, when the pressing part 427 is opposite to the stop member 31, the pressing part 427 will push the stop member 31 to move to the unlock position. When the pressing part 427 separates from the stop member 31, the stop member 31 always has a tendency to move towards the locked position under the drive of the elastic member 32. This realizes that during one rotation of the transmission gear 421, the transmission gear 421 can periodically drive the stop member 31 to the unlock position and periodically separate from the stop member 31.

[0061] Specifically, please continue to refer to Figure 4 and Figure 6 In this embodiment, the pressing part 427 is a flange with a semi-circular or fan-shaped cross-section. When the flange abuts against the stop 31, it can push the stop 31 to the unlock position. When the flange separates from the stop 31, the stop 31 can move to the locked position under the elastic force of the elastic member 32. As an alternative, the pressing part 427 is a cam. When the transmission member 42 rotates at a first angle, the cam abuts against the stop 31 and pushes the stop 31 to the unlock position. When the cam rotates at a second angle, the cam separates from the stop 31, and the stop 31 moves to the locked position under the elastic force of the elastic member 32.

[0062] Alternatively, please refer to Figure 4 and Figure 6The transmission component 42 also includes a limiting post 428. The transmission gear 421, the pressing part 427, and the limiting post 428 are coaxial and fixedly connected in sequence. The outer diameters of the transmission gear 421 and the limiting post 428 are both larger than the outer diameter of the pressing part 427. When the pressing part 427 abuts against the stop 31, the stop 31 is located between the transmission gear 421 and the limiting post 428. With this configuration, the end faces of the transmission gear 421 and the limiting post 428 are respectively opposite to the two sides of the stop 31, so as to restrict the position of the stop 31 by the end faces of the transmission gear 421 and the limiting post 428, thereby ensuring reliable unlocking of the stop 31.

[0063] Alternatively, please refer to Figure 3 and Figure 8 The gate mechanism also includes a second transmission assembly 6. The transmission shaft 41 is connected to the gate 2 via the second transmission assembly 6. The second transmission assembly 6 includes a first transition gear 61, a gate gear 62, and a rack 63. The first transition gear 61 is fixedly sleeved on the transmission shaft 41. The gate gear 62 is directly or intermittently meshed with the first transition gear 61. The rack 63 is fixedly connected to the gate 2 and extends along the direction of movement of the gate 2. The rack 63 also meshes with the gate gear 62. With this configuration, when the transmission shaft 41 rotates, it drives the first transition gear 61 to rotate synchronously, thereby moving the gate 2 to the open or closed position through the meshing of the first transition gear 61, gate gear 62, and rack 63. In this embodiment, an indirect meshing scheme between the gate gear 62 and the first transition gear 61 is provided as an example. In other embodiments, the gate gear 62 can also directly mesh with the first transition gear 61.

[0064] Alternatively, please refer to Figure 8 The gate mechanism includes two second transmission components 6, which are located at both ends of the transmission shaft 41. The racks 63 of the two second transmission components 6 are fixed to both ends of the gate 2, and the first transition gears 61 of the two second transmission components 6 are fixed to both ends of the transmission shaft 41. With this configuration, the gate 2 is driven to move by the two second transmission components 6, which can further improve the stability of the opening and closing movement of the gate 2.

[0065] Alternatively, please refer to Figures 1 to 3The frame 1 includes an outer support 12. The elastic force of the elastic member 32 causes the stop member 31 to always have a rotational tendency to approach the outer support 12. When the gate 2 is in the open position, the gate 2 retracts between the stop member 31 and the outer support 12. When the gate 2 is in the closed position, the gate 2 extends out from between the stop member 31 and the outer support 12. This configuration ensures that when the gate 2 moves from the open position to the closed position, the stop 31 remains in contact with the inner surface of the gate 2 under the action of elastic force. The gate 2 prevents the stop 31 from extending into the path of the gate 2 moving from the closed position to the open position. When the gate 2 moves to the closed position, the stop 31 separates from the gate 2 along the rotation direction of the stop 31. Under the action of the elastic force of the elastic member 32, the stop 31 can extend into the path of the gate 2 moving from the closed position to the open position to lock the position of the gate 2. When the stop 31 is driven to the unlocked position by the transmission member 42, the stop 31 exits the path of the gate 2 moving from the closed position to the open position, and the gate 2 can move to the open position. When the gate 2 moves to the open position, the gate 2 prevents the stop 31 from extending into the path of the gate 2 moving from the closed position to the open position, so that the gate 2 can smoothly move to the closed position when it closes again.

[0066] Alternatively, please refer to Figure 1 , Figure 3 and Figure 8The frame 1 also includes an inner support 11 fixedly connected to the outer support 12. The inner support 11 includes a support shaft 111 and a transition shaft 112 arranged parallel to and spaced apart from the transmission shaft 41. The locking assembly 3 includes two stops 31, both of which are rotatably sleeved on the support shaft 111. Both stops 31 can rotate around the support shaft 111 to the locked position and the unlocked position. The first transmission assembly 4 includes two transmission members 42, both of which are sleeved on the transmission shaft 41. The two transmission members 42 are arranged one-to-one with the two stops 31. The gate mechanism also includes a third transmission assembly 7, which includes two second transition gears 71, both of which are fixedly sleeved on the transition shaft 112. The two second transition gears 71 are connected to the transmission gears 421 of the two transmission members 42 in a one-to-one transmission connection. One of the two second transition gears 71 is connected to the motor 5. With this arrangement, the gate 2 can be locked and closed simultaneously by the two stops 31, which can further improve the safety of the gate mechanism. Specifically, when the output shaft 52 of the motor 5 rotates, the transition shaft 112 rotates via the second transition gear 71 connected to the motor 5, and then the two second transition gears 71 drive the two transmission components 42 to rotate. The two transmission components 42 simultaneously drive the two stop components 31 to rotate to the unlocked position; or, the two transmission components 42 drive the transmission shaft 41 to rotate synchronously and in the same direction, so that the transmission shaft 41 drives the gate 2 to open and close via the second transmission assembly 6. Preferably, the output shaft 52 of the motor 5 is fixed with a motor gear 51, and when the output shaft 52 of the motor 5 rotates, the motor gear 51 is connected to the transmission gear 421 via the third transmission assembly 7.

[0067] Alternatively, please refer to Figure 2 , Figure 3 and Figure 8 The inner support 11 also includes a first plate 113, a second plate 114, and a third plate 115 connected between the first plate 113 and the second plate 114. The motor 5 is fixedly connected to the first plate 113. The two ends of the support shaft 111 and the transition shaft 112 are supported by the first plate 113 and the second plate 114. The inner support 11 also includes a fourth plate 116, a fifth plate 117, and a sixth plate 118. The fourth plate 116 is spaced apart from the first plate 113, and the fifth plate 117 is spaced apart from the second plate 114. The first plate 113 and the second plate 114 are located between the fourth plate 116 and the fifth plate 117. The sixth plate 118 is connected between the fourth plate 116 and the fifth plate 117 and is also fixedly connected to the third plate 115. The two ends of the transmission shaft 41 are supported by the fourth plate 116 and the fifth plate 117. Preferably, the first transition gear 61 and the portal gear 62 of the two second transmission components 6 are respectively installed on the fourth plate 116 and the fifth plate 117.

[0068] Alternatively, please refer to Figure 8The third transmission component 7 also includes a first gear 72 rotatably mounted on the first plate 113, a second gear 73 coaxial with and fixedly connected to the first gear 72, and a third gear 74 coaxial with and fixedly connected to the second transition gear 71. The first gear 72 meshes with the motor gear 51, and the second gear 73 meshes with the third gear 74. When the output shaft 52 of the motor 5 rotates, the torque of the motor 5 is transmitted to the second transition gear 71 in sequence through the motor gear 51, the first gear 72, the second gear 73 and the third gear 74, and then drives the transmission component 42 to rotate through the second transition gear 71.

[0069] Alternatively, please refer to Figure 1 , Figure 2 , Figure 9 and Figure 10 The outer support 12 includes a first wall 121 and a second wall 122 arranged at relative intervals, and a third wall 123 connected between the first wall 121 and the second wall 122. The first wall 121 is provided with a first guide groove 124, the second wall 122 is provided with a second guide groove (not shown in the figure), and the third wall 123 is rotatably provided with a limiting wheel 125. The gate 2 is located between the first wall 121 and the second wall 122. The gate 2 includes a first guide end opposite to the first wall 121 and a second guide end opposite to the second wall 122. The first guide end is provided with at least two rotatable first guide wheels 21, and at least two first guide wheels 21 are inserted into the first guide groove 124. The second guide end is provided with at least two rotatable second guide wheels 22, and at least two second guide wheels 22 are inserted into the second guide groove. When the gate 2 moves between the open position and the closed position, the first guide wheel 21 rolls along the first guide groove 124, the second guide wheel 22 rolls along the second guide groove, and the limiting wheel 125 rolls along the outer surface of the gate 2. With this configuration, the first guide wheel 21 and the second guide wheel 22 at both ends of the gate 2 are respectively inserted into the first guide groove 124 and the second guide groove, which restricts the position of the gate 2 relative to the frame 1, so that the gate 2 can only move along the extension direction of the two guide grooves. At the same time, the position of the gate 2 is further restricted by the rolling engagement of the limiting wheel 125 with the outer surface of the gate 2. This allows the gap between the guide wheel and the guide groove to be set relatively large, which facilitates installation, reduces manufacturing costs, and does not affect the stability of the opening and closing movement of the gate 2.

[0070] Alternatively, please refer to Figure 2 and Figure 3The first wall 121 and the fourth plate 116 are spaced apart, and the second wall 122 and the fifth plate 117 are spaced apart. Support columns 13 are connected between the first wall 121 and the fourth plate 116, and between the second wall 122 and the fifth plate 117, to ensure the structural stability of the frame 1. Optionally, two second transmission components 6 are respectively disposed between the first wall 121 and the fourth plate 116, and between the second wall 122 and the fifth plate 117. Optionally, the rack 63 and the limiting wheel 125 are arranged on the inner and outer sides of the gate 2 and together clamp the gate 2, making the opening and closing movement of the gate 2 more stable and smooth.

[0071] Alternatively, please refer to Figure 3 , Figure 9 and Figure 10 The cross-sectional shape of the third wall 123 matches the cross-sectional shape of the gate 2. In this embodiment, the gate 2 is rotatably connected to the frame 1, and the cross-sectional shapes of both the gate 2 and the third wall 123 are circular arcs. When the gate 2 is in the open position, the gate 2 and the third wall 123 are concentric circular arcs. In other embodiments, the gate 2 can also be slidably connected to the frame 1, and the cross-sectional shapes of both the gate 2 and the third wall 123 are straight lines. When the gate 2 is in the open position, the gate 2 retracts between the third wall 123 and the stop member 31, and the gate 2 and the third wall 123 are arranged parallel and spaced apart.

[0072] Alternatively, please refer to Figure 10 The portal gear 62 is rotatably mounted on the inner bracket 11. When the drive shaft 41 rotates, it drives the portal gear 62 to rotate through the first transition gear 61. The portal gear 62 rolls along the rack 63, driving the gate 2 to open or close. The rotation center of the gate 2, the rotation center of the portal gear 62, and the rotation center of the limit wheel 125 are located on the same straight line (e.g., Figure 10 As shown in the straight line L, this arrangement ensures that the forces exerted on the gate 2 by the gate gear 62 or the limit wheel 125 pass through the rotation center of the gate 2, minimizing the impact on the rotation of the gate 2 and further guaranteeing the smooth and stable opening and closing of the gate 2.

[0073] Alternatively, please refer to Figures 11 to 13The inner surface of the gate 2 is provided with a retaining strip 23. The retaining strip 23 includes a guide surface 231 extending along the movement direction of the gate 2 and a blocking surface 232 perpendicular to the guide surface 231. The blocking surface 232 is located at the end of the guide surface 231 along the opening direction of the gate 2. When the gate 2 is in the closed position and the stop 31 is in the locked position, the stop 31 is located downstream of the blocking surface 232 and opposite to the blocking surface 232 along the opening direction of the gate 2 to prevent the gate 2 from moving to the open position. When the transmission member 42 drives the stop 31 to the unlocked position, the stop 31 separates from the retaining strip 23. When the gate 2 moves from the closed position to the open position and from the open position to the closed position, the stop 31 abuts against the guide surface 231 under the action of the elastic force of the elastic member 32. During the process of the gate 2 moving to the closed position or the open position, the guide surface 231 always prevents the stop 31 from extending into the path of the gate 2 moving from the closed position to the open position. With this configuration, during the movement of the gate 2 from the open position to the closed position, and during the movement of the gate 2 from the closed position to the open position, when the pressing part 427 separates from the stop member 31, the stop member 31 abuts against the guide surface 231 under the action of the elastic member 32, and the guide surface 231 prevents the stop member 31 from extending into the path of the gate 2 moving from the closed position to the open position; when the gate 2 is in the closed position and the stop member 31 is in the locked position, the guide surface 231 separates from the stop member 31, and the stop member 31 enters the path of the gate 2 moving from the closed position to the open position under the drive of the elastic member 32 and abuts against the blocking surface 232, so as to lock the position of the gate 2 in the closed position.

[0074] This embodiment also provides a banknote collecting device, which includes a receiving cavity for storing banknotes and a gate mechanism. The receiving cavity has an outlet. When the gate 2 is in the closed position, the outlet is closed by the gate 2; when the gate 2 is in the open position, the outlet is opened. This banknote collecting device uses the aforementioned gate mechanism, which ensures high security of the gate mechanism while also reducing its manufacturing cost.
