TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic levitation conveying, in particular to a distributed magnetic levitation non-continuous precision conveying device. BACKGROUND

[0002] The distributed magnetic levitation non-continuous precision conveying device has a wide application prospect in industrial production. The traditional conveying equipment such as the belt conveyor and the chain conveyor can meet the requirements of conventional production and logistics to a certain extent, but their precision and flexibility are relatively poor, and it is difficult to meet the needs of precision manufacturing and high-precision transportation. Especially in the electronic, semiconductor, medical, precision instrument and other industries, the accuracy, stability and safety of the conveying process are extremely high, and the traditional conveying equipment has been difficult to adapt to the special needs of these high-end fields. Therefore, a distributed magnetic levitation non-continuous precision conveying device is proposed.

[0003] The high-speed linear return flow mechanism capable of carrying a carrier disclosed in the patent No. CN221164972U has solved the technical defects of the traditional conveying mechanism, which not only takes a long time for the same displacement distance, but also needs secondary positioning mechanism to realize accurate positioning. However, the similar structure still has many defects in actual use, such as the existing precision conveying system, the technical means for realizing complex direction adjustment has certain limitations; the traditional mechanical device can only realize simple horizontal or vertical movement through fixed guide rails, and cannot meet the efficient and flexible requirements of multi-directional accurate adjustment position demand, which limits the adaptability and flexibility of the device and makes it difficult to cope with complex conveying tasks and diversified working environment.

[0004] Therefore, the above technical problems need to be solved. SUMMARY

[0014] The fixed frame consists of two half-hoop components, which are fixedly connected by bolts. Limit strips are fixedly installed on the outer side of each half-hoop component, and the two half-hoop components are engaged in the slot on one side of the lifting seat by the limit strips.

[0015] The elastic locking assembly consists of a telescopic pin plate, a slider, and a spring telescopic component.

The synchronous gear is sleeved on the outside of the spline transmission rod through the spline through hole. The top of the other synchronous gear is connected to the rotating seat for transmission.

[0017] Preferably, the linear mechanism consists of a mounting bracket, a lead screw, a lead sleeve, and a servo motor. The lead screw is rotatably mounted inside the mounting bracket.

[0020] The beneficial effects of this invention are:

[0021] The technical solution of this invention uses a servo motor to drive a threaded rod to rotate. The threaded rod, through a mating unlockable threaded drive assembly, enables precise lifting and lowering of the lifting mechanism, thereby adjusting the vertical position of the adjustable guide rail. When the unlockable threaded drive assembly moves to the bottom of the intermittent drive assembly, it abuts against the intermittent drive assembly, achieving spline engagement transmission. The intermittent drive assembly drives the synchronous belt assembly to rotate through the spline transmission rod, causing the rotating seat to rotate and adjust its orientation. A linear mechanism drives the adjustable guide rail to move horizontally, thus achieving multi-directional adjustment of the adjustable guide rail's connection position. Through the coordinated work of the servo motor, threaded rod, unlockable threaded drive assembly, intermittent drive assembly, synchronous belt assembly, and linear mechanism, not only can high-precision vertical position adjustment be achieved, but also precise adjustment of horizontal movement and rotation direction can be achieved through different combinations of drive components. This achieves highly precise horizontal, vertical, and multi-angle track switching, which not only improves the equipment's working efficiency but also widely adapts to different guide rail connection requirements, solving the problem of difficulty in handling complex conveying tasks and diverse working environments, and meeting the requirements of precision conveying systems for multi-directional, high-precision position adjustment.

[0041] The following will be combined with the appendix Figure 1 To be continued Figure 17 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] A distributed magnetic levitation non-continuous precision conveying device includes a housing 1, multiple anti-detachment mechanisms 3, and a lifting mechanism 5. It also includes a drive mechanism 6 fixedly installed inside the housing 1 on one side. The drive mechanism 6 is connected to the lifting mechanism 5. The lifting mechanism 5 consists of a lifting seat 501, a synchronous belt assembly 502, and a rotating seat 503. A slot is provided on one side of the lifting seat 501. The synchronous belt assembly 502 is rotatably installed on the top of the lifting seat 501. The output end of the synchronous belt assembly 502 is connected to the rotating seat 503, and the rotating seat 503 is fixedly installed on the top of one side of the lifting seat 501. A linear mechanism 4 is fixedly installed on the top of the lifting mechanism 5, and an adjustable guide rail 2 is fixedly installed on the top of the linear mechanism 4.

[0043] The drive mechanism 6 includes a mounting bracket 601, an intermittent drive assembly 602, a threaded rod 603, an unlockable threaded drive assembly 604, a servo motor 605, a spline transmission rod 606, and a second encoder 607. The unlockable threaded drive assembly 604 consists of a threaded sleeve 6041, a fixed sleeve 6042, an elastic locking assembly 6043, and a contact plate 6044. The outer side of the threaded sleeve 6041 has a pin groove, and the inner side of the contact plate 6044 has a V-shaped sliding groove. The fixed sleeve 6042 is fixedly sleeved on the outer side of the threaded sleeve 6041. The elastic locking assembly 6043 is threadedly installed inside the fixed sleeve 6042. The contact plate 6044 is movably installed inside the fixed sleeve 6042 through the elastic locking assembly 6043, and the contact plate 6044 penetrates through the fixed sleeve 6042.

[0044] The rotational motion of the threaded rod 603 drives the threaded sleeve 6041 to move linearly along the threaded rod 603. The linearly moving threaded sleeve 6041 drives the contact plate 6044 and the lifting mechanism 5 to move up and down through the fixed sleeve frame 6042.

[0045] The lifting mechanism 5, which moves up and down, drives the adjustable guide rail 2 to move up and down through the linear mechanism 4, thereby realizing the vertical movement of the adjustable guide rail 2 and changing the vertical connection position. When the contact plate 6044 moves up to the bottom of the intermittent drive component 602, it squeezes the intermittent drive component 602, realizing the dynamic connection of the intermittent drive component 602. The contact plate 6044 drives the elastic locking component 6043 away from the pin groove on the outside of the threaded sleeve 6041 through the V-shaped slide groove, thereby unlocking the threaded sleeve 6041. When the threaded rod 603 continues to rotate, the threaded drive of the threaded sleeve 6041 is released. At the same time, the threaded rod 603 continues to rotate, driving the intermittent drive component 602 to rotate intermittently. The intermittent drive component 602 drives the spline transmission rod 606 to rotate intermittently. The intermittently rotating intermittent drive component 602 drives the rotating seat 503 to rotate intermittently through the synchronous belt component 502. The intermittently rotating rotating seat 503 drives the adjustable guide rail 2 to rotate and adjust the angle through the linear mechanism 4, changing the connection position of the adjustable guide rail 2.

[0046] The adjustable guide rail 2 is driven to move vertically by the drive mechanism 6, lifting mechanism 5, and linear mechanism 4 in coordination, thereby changing the vertical connection position of the adjustable guide rail 2; and the adjustable guide rail 2 is driven to rotate, thereby changing the connection position of the adjustable guide rail 2 in multiple directions. The adjustable guide rail 2, which moves vertically and rotates, is adjusted to a horizontal position by the linear mechanism 4, thereby realizing the switching of horizontal, vertical and multi-angle tracks.

[0047] It should be noted that the drive mechanism 6 operates by the servo motor 605 driving the threaded rod 603 to rotate. The rotating threaded rod 603, in conjunction with the unlockable threaded drive assembly 604, precisely controls the lifting operation of the lifting mechanism 5, thereby achieving precise adjustment of the vertical position of the adjustable guide rail 2.

[0048] When the unlockable threaded drive assembly 604 moves to the bottom of the intermittent drive assembly 602, it abuts against the intermittent drive assembly 602 to achieve spline engagement transmission. The intermittent drive assembly 602 drives the synchronous belt assembly 502 to drive the rotating seat 503 to rotate through the spline transmission rod 606. The rotating seat 503 drives the adjustable guide rail 2 to rotate and adjust its position through the linear mechanism 4, providing multiple docking positions and widely adapting to different guide rail docking requirements.

[0049] The adjustable guide rail 2 is driven to move horizontally by the linear mechanism 4, thereby adjusting the horizontal position of the adjustable guide rail 2.

[0050] The entire device, through the servo motor 605, threaded rod 603, unlockable threaded drive assembly 604, intermittent drive assembly 602, synchronous belt assembly 502 and linear mechanism 4 in the drive mechanism 6, realizes the vertical movement, rotational movement and precise adjustment of the horizontal position of the adjustable guide rail 2, thereby achieving efficient guide rail connection and conveying in different directions and meeting the requirements of precision conveying.

[0051] like Figures 2 to 5 As shown, the mounting bracket 601 consists of a mounting base 6011, two slide rails 6012, and a mounting top bracket 6013. The two slide rails 6012 are fixedly installed on both sides of the top of the mounting base 6011 and are installed opposite to each other. The mounting top bracket 6013 is fixedly installed on the top of the two slide rails 6012 and is fixedly installed on the top wall of the chassis 1. A position sensor 608 is embedded on one side of the top of the mounting base 6011.

[0052] It should be noted that the mounting bracket 6013 has a guide hole inside, and a mounting hole is provided at the top of the guide hole. The mounting hole provides a rotational mounting position for the transmission turntable 6021, and the guide hole provides a movable guide for the spline sleeve 6026.

[0053] The slide rail bracket 6012 provides a sliding position for the slide rail sleeves on both sides of the lifting seat 501, guides the smooth movement of the slide rail sleeves, and ensures that the lifting seat 501 remains stable during lifting and moving.

[0054] The position sensor 608 detects the lifting position of the lifting seat 501 in real time and transmits the detection electrical signal to the controller at the top of the chassis 1. When the controller calculates that the lifting position 501 has reached the set value, the controller controls the servo motor 605 to stop running, thus ensuring the accuracy of the lifting position 501.

[0055] like Figures 11 to 12 As shown, the intermittent drive assembly 602 consists of a transmission turntable 6021, a toggle lever 6022, and an intermittent turntable 6023. One end of the toggle lever 6022 is fixedly installed on the top of the transmission turntable 6021. The intermittent turntable 6023 has toggle grooves equidistantly opened inside. The toggle lever 6022 is intermittently driven to the intermittent turntable 6023 through the toggle grooves. A spline linkage rod 6024 is fixedly installed at the bottom of the transmission turntable 6021. A spring 6025 is sleeved on the outside of the spline linkage rod 6024. A spline sleeve 6026 is dynamically sleeved on the outside of the spline linkage rod 6024.

[0056] It should be noted that the finely designed actuating groove inside the intermittent turntable 6023 can form a specific disengagement and engagement state with the movement of the actuating lever 6022 during rotation, thereby outputting periodic intermittent motion; and the intermittent turntable 6023 can control the current angle, so that the power output by the intermittent turntable 6023 through the synchronous belt assembly is transmitted intermittently at the same angle, which is beneficial for precise control of the rotation adjustment angle.

[0057] When the unlockable threaded drive assembly 604 moves to the bottom of the intermittent drive assembly 602, it abuts upward against the bottom of the spline sleeve 6026 in the intermittent drive assembly 602, causing the spline sleeve 6026 to move upward into the guide hole inside the mounting bracket 6013. The guide hole provides space for the spline sleeve 6026 to move upward, and the upward-moving spline sleeve 6026 compresses the spring 6025 on the outside of the spline linkage rod 6024. When the spline sleeve 6026 moves to the spline position of the spline linkage rod 6024, the spline sleeve 6026 and the spline linkage rod 6024 are splined and connected for transmission. The threaded rod 603 transmits the rotational force to the transmission turntable 6021 through the spline connection spline sleeve 6026 and spline linkage rod 6024. The transmission turntable 6021 drives the actuating rod 6022 to rotate. The rotating actuating rod 6022 interacts with the actuating groove in the intermittent turntable 6023 to achieve intermittent transmission. The intermittently rotating intermittent turntable 6023 drives the synchronous belt assembly 502 to rotate through the spline transmission rod 606. The rotating synchronous belt assembly 502 drives the adjustable guide rail 2 on the top of the linear mechanism 4 to rotate and adjust the connection position through the rotating seat 503.

[0058] When the servo motor 605 drives the threaded rod 603 to rotate in the opposite direction, the unlockable threaded drive assembly 604 moves down away from the bottom of the intermittent drive assembly 602, releasing the resistance force on the spline sleeve 6026. The compressed spring 6025 returns to its original position, moving down against the spline sleeve 6026, releasing the spline connection transmission between the spline sleeve 6026 and the spline linkage rod 6024. This causes the lowered unlockable threaded drive assembly 604 to drive the lifting mechanism 5 to move down, so that the lifting mechanism 5 drives the adjustable guide rail 2 to move down to the same horizontal position as the transverse extension guide rail 103 through the linear mechanism 4. The linear mechanism 4 adjusts the horizontal position of the adjustable guide rail 2 so that the adjustable guide rail 2 mates with the transverse extension guide rail 103.

[0059] like Figures 9 to 11 As shown, a spline head is fixedly installed on the top of the threaded rod 603, and the spline head is movably connected to the bottom of the spline sleeve 6026. The bottom end of the threaded rod 603 is fixedly connected to the output end of the servo motor 605, and the servo motor 605 is fixedly installed on the bottom of the mounting base 6011.

[0060] It should be noted that the spline head at the top of the threaded rod 603 serves to connect movably with the bottom of the spline sleeve 6026, ensuring that the two can rotate in tandem while maintaining the change in axial distance; when the servo motor 605 is powered on, it drives the threaded rod 603 to rotate in both directions. The rotating threaded rod 603 drives the unlockable thread drive assembly 604 to move reciprocally in a straight line along the seat of the threaded rod 603. The unlockable thread drive assembly 604 drives the lifting mechanism 5 to perform lifting operations.

[0061] like Figures 9 to 11 As shown, a threaded head is fixedly installed at the top of the spline drive rod 606, and the spline drive rod 606 is fixedly connected to the bottom of the intermittent turntable 6023 through the threaded head. A shaft that passes through the mounting base 6011 is fixedly installed at the bottom of the spline drive rod 606, and a second encoder 607 is installed on the spline drive rod 606 through the shaft. The second encoder 607 is fixedly installed at the bottom of the mounting base 6011.

[0062] It should be noted that the threaded end of the spline drive rod 606 is used to fix and connect the intermittent turntable 6023, ensuring a stable connection between the two and guaranteeing the accuracy of the transmission. When the spline drive rod 606 rotates, the second encoder 607 checks the number of rotations of the spline drive rod 606 in real time, providing reliable data support for the precise control of the device, and making it easy for the controller to calculate the rotation angle of the adjustable guide rail 2 based on the number of rotations of the spline drive rod 606.

[0063] like Figures 13 to 16As shown, the fixed sleeve 6042 consists of two half-hoop components, which are fixedly connected by bolts. Limit strips are fixedly installed on the outer side of each half-hoop component, and the two half-hoop components are snapped into the slot on one side of the lifting seat 501 by the limit strips. The elastic locking component 6043 consists of a telescopic pin plate 60431, a slider 60432, and a spring telescopic component 60433. The slider 60432 is fixedly installed on one side of the telescopic pin plate 60431. The slider 60432 extends into the V-shaped groove inside the contact plate 6044. The spring telescopic component 60433 is threadedly installed inside the fixed sleeve 6042. The spring telescopic component 60433 consists of a threaded tube, a spring, and a telescopic rod, and one end of the telescopic rod is fixedly connected to the end face of the telescopic pin plate 60431.

[0064] It should be noted that the two half-hoop kits are fixedly connected by bolts to form a complete sleeve frame, which is used to fix the threaded sleeve 6041. The fixing sleeve frame 6042 is engaged with the slot on one side of the lifting seat 501 through the limit strip on the outside to form a fixed structure, so that when the threaded sleeve 6041 moves linearly, the lifting seat 501 is driven to move up and down through the fixing sleeve frame 6042.

[0065] The telescopic pin plate 60431 engages with the V-shaped groove inside the contact plate 6044 via a slider. When the contact plate 6044 is subjected to external force, the telescopic pin plate 60431 is driven to telescopically move through the V-shaped groove inside the contact plate 6044 and the slider. This allows the telescopic pin plate 60431 to dynamically lock and unlock the threaded sleeve 6041 by engaging the pin groove on one side of the threaded sleeve 6041. This enables the threaded sleeve 6041 to be dynamically locked and unlocked, and changes the transmission mode of the threaded rod 603. When the threaded sleeve 6041 is locked, the threaded rod 603 drives the threaded sleeve 6041 to move linearly. When the threaded sleeve 6041 is unlocked, the threaded sleeve 6041 abuts against the intermittent drive component 602, causing the threaded rod 603 to engage with the intermittent drive component 602.

[0066] like Figures 7 to 8 As shown, slide rail sleeves are fixedly installed on both sides of the lifting seat 501. The synchronous belt assembly 502 consists of a synchronous toothed belt and two synchronous gears. The synchronous toothed belt is wrapped around the outside of the two synchronous gears. One of the synchronous gears has a spline through hole inside. The synchronous gear is sleeved on the outside of the spline transmission rod 606 through the spline through hole. The top of the other synchronous gear is connected to the rotating seat 503 for transmission.

[0067] It should be noted that the lifting seat 501 is slidably connected to two slide rail frames 6012 via a slide rail sleeve, which guides the vertical movement of the lifting seat 501 and ensures the stability of the vertical movement of the lifting seat 501. The main function of the synchronous belt assembly 502 is to transmit power and maintain the synchronous movement of the two synchronous gears. It ensures that the two synchronous gears operate synchronously by wrapping around the outside of the two synchronous gears. One of the synchronous gears has a spline through hole inside, which can transmit power by inserting it into the spline transmission rod 606. The other synchronous gear is mechanically connected to the rotating seat 503, so that its spline transmission rod 606 drives the synchronous gear inserted into the spline through hole to rotate. The rotating synchronous gear is transmitted to the synchronous gear fixedly installed at the bottom of the rotating seat 503 through the synchronous toothed belt, thereby realizing the linkage between the two, and thus driving the rotating seat 503 to rotate, achieving efficient power transmission and driving effect.

[0068] like Figures 5 to 6 As shown, the linear mechanism 4 consists of a mounting frame 401, a lead screw 403, a threaded sleeve 404, and a servo motor 405. The lead screw 403 is rotatably mounted inside the mounting frame 401. The output end of the servo motor 405 is fixedly connected to one end of the lead screw 403, and the servo motor 405 is fixedly mounted on one side of the mounting frame 401. The other end of the lead screw 403 is sleeved with a first encoder 406, and the first encoder 406 is fixedly mounted on the other side of the mounting frame 401. The threaded sleeve 404 is threaded onto the outside of the lead screw 403. Two guide slide rods 402 are installed through both sides of the threaded sleeve 404, and the two guide slide rods 402 are fixedly mounted inside the mounting frame 401.

[0069] It should be noted that the mounting bracket 401 serves as a support structure, providing a mounting base for the lead screw 403, servo motor 405, guide slide 402, and threaded sleeve 404. The lead screw 403 rotates under the drive of the servo motor 405, thereby driving the threaded sleeve 404, which is threaded to it, to move linearly. The guide slide 402 guides the movement trajectory of the threaded sleeve 404, ensuring its precise linear motion. The first encoder 406 monitors the rotational position of the lead screw 403 in real time, achieving precise positioning and feedback control. Specifically, the servo motor 405 drives the lead screw 403 to rotate. The screw sleeve 404 is driven to make linear displacement along the guide slide rod 402. The linear displacement of the screw sleeve 404 drives the adjustable guide rail 2 to move linearly. The first encoder 406 realizes precise position control and feedback, ensuring the stability and accuracy of the linear movement of the adjustable guide rail 2, and achieving the purpose of flexibly adjusting the horizontal position of the adjustable guide rail 2. When rotating the adjustable guide rail 2, the above actions move the adjustable guide rail 2 to the center position of the mounting shaft frame 401, ensuring that the adjustable guide rail 2 does not touch, and also facilitating the subsequent horizontal movement of the adjustable guide rail 2 to open and close the anti-detachment mechanism 3.

[0070] likeFigures 1 to 3 As shown, two sets of transverse guide rails 101 are fixedly installed on both sides of the top of the chassis 1, and a longitudinal guide rail 102 is installed on the back of the top of the chassis 1 via a bracket. An extended transverse extension guide rail 103 is fixedly installed inside the chassis 1 via a bracket. A moving trolley 104 is movably installed on the top of the transverse guide rails 101, the longitudinal guide rails 102, the transverse extension guide rails 103, and the adjustable guide rail 2.

[0071] It should be noted that a controller is fixedly installed on one side of the top of the chassis 1. The controller is electrically connected to the electrical equipment inside the device through wires, which facilitates the calculation of the received inspection signals and enables high-precision control of the device's lifting, horizontal, and rotating movements.

[0072] The two sets of transverse guide rails 101 are transverse double rails. The drive mechanism 6, together with the lifting mechanism 5, drives the adjustable guide rail 2 to move upward to the same horizontal plane as the transverse guide rail 101 through the linear mechanism 4. Then, the linear mechanism 4 drives the adjustable guide rail 2 to dynamically adjust its horizontal position, so that the adjustable guide rail 2 can be dynamically connected between the two sets of transverse guide rails 101 to realize the transverse double rail path, so that the moving trolley 104 can dynamically switch tracks and move laterally on the two sets of transverse guide rails 101.

[0073] The longitudinal guide rail 102 provides a longitudinal sliding path for the moving trolley 104. When the drive mechanism 6, in conjunction with the lifting mechanism 5, drives the adjustable guide rail 2 to move upward through the linear mechanism 4 and then adjusts the angle, after the angle adjustment is completed, the drive mechanism 6, in conjunction with the lifting mechanism 5, drives the adjustable guide rail 2 to move downward to the same horizontal plane as the longitudinal guide rail 102 through the linear mechanism 4. Then, the linear mechanism 4 drives the adjustable guide rail 2 to move horizontally and dock with the longitudinal guide rail 102, so that the moving trolley 104 can move longitudinally. This adds an additional lateral sliding path, allowing the moving trolley 104 to achieve a wider range of lateral movement.

[0074] The drive mechanism 6, together with the lifting mechanism 5, drives the adjustable guide rail 2 to move upward to the same horizontal plane as the transverse extension guide rail 103 through the linear mechanism 4. Then, the linear mechanism 4 drives the adjustable guide rail 2 to move horizontally and dock with the longitudinal guide rail 102, providing additional degrees of freedom for adjustment.

[0075] The multi-layered guide rail structure provides the moving trolley 104 with flexible three-dimensional spatial movement capabilities, enabling precise position adjustment and high-precision positioning in confined spaces.

[0076] like Figure 1 , Figure 2 , Figure 3 , Figure 17As shown, the anti-detachment mechanism 3 consists of an unlocking component 301 and a limiting component 302. The unlocking component 301 is fixedly installed at the bottom of both sides of the adjustable guide rail 2, and the limiting component 302 is located on one side of the transverse guide rail 101, the longitudinal guide rail 102, and the transverse extension guide rail 103, respectively. The unlocking component 301 consists of a mounting sleeve 3011 and an arc-shaped track component 3012, with the arc-shaped track component 3012 fixedly installed inside the mounting sleeve 3011. The limiting component 302 consists of a fixed shaft bracket. Composed of 3021, two spiral springs 3022 and baffle 3023, the two spiral springs 3022 are fixedly installed on both sides inside the fixed shaft frame 3021, the two sides of the bottom end of the baffle 3023 are fixedly connected to the two spiral springs 3022 respectively through shafts, a contact wheel 3024 is fixedly installed on one side of the baffle 3023, and the contact wheel 3024 is dynamically contacted with the arc-shaped track component 3012, and a rubber block 3025 is fixedly installed on one side of the top end of the baffle 3023;

[0077] It should be noted that the moving trolley 104 on the guide rail is limited in the non-connected state of the limiting component 302 to prevent the moving trolley 104 from derailing. Specifically, without external force against the limiting component 302, the baffle 3023 is flipped to one side of the moving trolley 104 by the spiral spring 3022 in the limiting component 302, and is limited by the soft contact between the rubber block 3025 and one side of the moving trolley 104.

[0078] The guide rail in the docking state is unlocked by the limiting component 302 at the corresponding position of the unlocking component 301. Specifically, when the adjustable guide rail 2 is driven to move horizontally by the linear mechanism 4, the limiting component 302 at the bottom of both sides of the adjustable guide rail 2 abuts against the unlocking component 301, releasing the limiting component 302 from restricting the moving trolley 104. Specifically, when the adjustable guide rail 2 moves horizontally to dock with the guide rail, the adjustable guide rail 2 moves to the corresponding limiting component 302 through the unlocking component 301 on one side. The arc-shaped track component 3012 in the unlocking component 301 abuts against the abutting wheel 3024, causing the baffle 3023 to flip around the shaft connected to the spiral spring 3022 as the axis and to wind around the spiral spring 3022. The flipped baffle 3023 drives the rubber block 3025 away from the moving trolley 104, releasing the restriction on the moving trolley 104.

[0079] By setting up the anti-derailment mechanism 3, the stable operation of the moving trolley 104 on the guide rail is ensured, avoiding derailment problems caused by improper connection or unexpected situations.
