[0041] Referring to Figure 1 and Figure 2 , the present utility model provides a barrier gate mechanism, comprising:

[0042] An installation member 1, the installation member 1 includes a first surface, a second surface and a through hole 10, the first surface and the second surface are disposed opposite to each other at intervals, and the through hole 10 penetrates through the first surface and the second surface;

[0043] At least one mounting seat 2, the mounting seat 2 is disposed on the first surface;

[0044] A driven rotating shaft 3, the driven rotating shaft 3 is rotatably connected to the mounting seat 2, and one end of the driven rotating shaft 3 is used for connecting to a gate rod 100 to drive the gate rod 100 to move;

[0045] A driving device 4, the driving device 4 is disposed on the second surface, the driving device 4 includes a driving member 41 and a driving rotating shaft 42, the driving member 41 is in transmission connection with the driving rotating shaft 42 to drive the driving rotating shaft 42 to rotate;

[0046] A link mechanism 5, the link mechanism 5 is in transmission connection between the driving rotating shaft 42 and the driven rotating shaft 3 to drive the driven rotating shaft 3 to rotate under the drive of the driving rotating shaft 42;

[0047] Wherein, the link mechanism 5 includes a driving swing arm 51, a driven swing arm 52 and a self-locking link 53, the first end of the driving swing arm 51 is fixedly connected to the driving rotating shaft 42, the first end of the driven swing arm 52 is fixedly connected to the driven rotating shaft 3, the self-locking link 53 is partially inserted into the through hole 10, and the first end of the self-locking link 53 is rotatably connected to the second end of the driving swing arm 51, the second end of the self-locking link 53 is rotatably connected to the second end of the driven swing arm 52, a lateral opening 530 is provided at the portion of the self-locking link 53 between its first end and second end, and the driving rotating shaft 42 is partially inserted into the lateral opening 530.

[0048] In this embodiment, the barrier gate mechanism utilizes the self-locking characteristic of the mechanical linkage mechanism and the coordinated operation of the driving device to achieve the automatic lifting and self-locking functions of the barrier rod 100. Its main principle is that the driving member 41 of the driving device 4 drives the active rotating shaft 42 to rotate, thereby driving the movement of the active swing arm 51, the driven swing arm 52, and the self-locking connecting rod 53 of the linkage mechanism 5. Finally, the rotation of the driven rotating shaft 3 is achieved, and the lifting of the barrier rod connected to the driven rotating shaft 3 is controlled. At the same time, by designing the geometric position and movement path of the self-locking connecting rod 53, the self-locking function of the barrier rod 100 is achieved.

[0049] The working process of the barrier gate mechanism of the present application solution is as follows:

[0050] Start of the driving device: The driving member 41 starts, driving the active rotating shaft 42 to rotate.

[0051] Drive the active swing arm to move: The active rotating shaft 42 rotates, and the active swing arm 51 fixedly connected thereto rotates accordingly.

[0052] Transmission of the linkage mechanism: The rotation of the active swing arm 51 is transmitted to the first end of the self-locking connecting rod 53 through its second end, causing the self-locking connecting rod 53 to rotate partially within the through hole 10. The second end of the self-locking connecting rod 53 is connected to the second end of the driven swing arm 52, thereby transmitting the movement to the driven swing arm 52. The first end of the driven swing arm 52 is fixedly connected to the driven rotating shaft 3. As the driven swing arm 52 rotates, the driven rotating shaft 3 also rotates accordingly.

[0053] Movement of the barrier rod: One end of the driven rotating shaft 3 is connected to the barrier rod 100. Through the rotation of the driven rotating shaft 3, the barrier rod 100 realizes the lifting action.

[0054] When performing the above actions, when the barrier rod 100 is in the horizontal or vertical position, the self-locking connecting rod 53 can make the force transmission path between the active swing arm 51 and the driven swing arm 52 become collinear or almost collinear through the setting of the lateral opening 530 and the preset swing path, thereby forming a mechanical dead point.

[0055] This dead point state makes it so that even when an external force acts to drive the barrier rod 100 or the driven rotating shaft 3, the barrier rod 100 will not rotate, achieving the self-locking effect, but it does not affect the rotation of the driven rotating shaft 3 driven by the driving member 41.

[0056] By setting the barrier gate mechanism with the above structure in the present application, the following effects are achieved:

[0057] First, stable and reliable control of the barrier rod: Through the transmission design of the linkage mechanism, the smooth lifting of the barrier rod is achieved, avoiding the impact and vibration caused by rapid movement.

[0058] Second, efficient self-locking function: The design of the self-locking link 53 ensures the self-locking function in critical positions (such as horizontal or vertical states), preventing the gate rod from accidentally moving due to external forces (such as wind or human interference), and improving the safety and reliability of the system.

[0059] Third, the design of the link mechanism 5 simplifies the transmission structure, achieving complex motion control and self-locking functions through fewer mechanical components, and reducing maintenance and failure rates.

[0060] Fourth, optimized space utilization: The above structure of this application is relatively concentrated and coherent, occupying a small area.

[0061] In summary, the gate mechanism in this embodiment realizes stable and reliable control of the gate rod and efficient self-locking function through the design of the drive device, link mechanism, and self-locking link, improving the safety and operating efficiency of the gate system.

[0062] Refer to Figure 1 and Figure 2 In some embodiments, the drive device 4 proposed in the embodiment of the present utility model is used to drive the link mechanism 5 to move between the first mechanical dead point position and the second mechanical dead point position;

[0063] Wherein, at the first mechanical dead point position, the driven swing arm 52 and the first end of the self-locking link 53 are collinear;

[0064] At the second mechanical dead point position, the driven swing arm 52 and the second end of the self-locking link 53 are collinear.

[0065] In this embodiment, the link mechanism 5 is composed of a driving swing arm 51, a driven swing arm 52, and a self-locking link 53. When the driving device 4 generates power and the driving member 41 is started, the driving main shaft 42 is driven to rotate. The driving main shaft 42 transmits the driving force to the driving swing arm 51, thereby driving the self-locking link 53 to rotate, and further driving the driven swing arm 52 to rotate, so that it reciprocates between the first mechanical dead point position and the second mechanical dead point position.

[0066] First mechanical dead point position: At this position, the driven swing arm 52 and the first end of the self-locking link 53 are collinear. This collinear state usually means that the driven swing arm 52 and the self-locking link 53 are in a stable limit position. When the gate rod 100 is driven by an external force, the driven rotating shaft 3 cannot rotate and cannot drive the driven swing arm 52 to rotate relative to the self-locking link 53.

[0067] Second mechanical dead point position: At this position, the driven swing arm 52 and the second end of the self-locking link 53 are collinear. Similar to the first mechanical dead point position, the driven swing arm 52 and the self-locking link 53 are in another stable limit position. At this time, when the gate rod 100 is driven by an external force, the driven rotating shaft 3 also cannot rotate and cannot drive the driven swing arm 52 to rotate relative to the self-locking link 53.

[0068] The first mechanical dead center position and the second mechanical dead center position respectively correspond to the positions where the gate rod 100 is lifted to the in-place position for vehicle release (the gate rod 100 is in a vertically erected state) and lowered to the in-place position (the gate rod 100 is in a horizontally placed state) for vehicle blocking proposed in the solution of the present application.

[0069] In the solution of the present application, the working process of the driving device 4 is as follows:

[0070] Initial position (the first mechanical dead center position): The driven swing arm 52 and the first end of the self-locking connecting rod 53 are collinear. At this time, the gate rod 100 is in a horizontal position, and the driving device 4 is started, and a driving force is applied starting from the initial collinear state (the first mechanical dead center position).

[0071] Link movement: As the driving member 41 outputs a driving force to drive the driving rotating shaft 42 to continuously apply a driving force to the driving swing arm 51, the self-locking connecting rod 53 is driven, and thus the driven swing arm 52 starts to rotate, leaves the first mechanical dead center position, and moves towards the second mechanical dead center position.

[0072] Intermediate transition: During the movement of the link mechanism 5, the angle between the driven swing arm 52 and the self-locking connecting rod 53 gradually changes until it reaches the second mechanical dead center position.

[0073] Second mechanical dead center position: The link mechanism 5 moves to the second mechanical dead center position. At this time, the driven swing arm 52 and the second end of the self-locking connecting rod 53 are collinear, and at this time, the gate rod 100 is in a vertical position.

[0074] In the driving device 4 of this embodiment, by driving the link mechanism 5 to reciprocate between two mechanical dead center positions, precise positioning and stable control of the system are achieved, which has the advantages of high efficiency, safety, and self-locking, and is applicable to mechanical systems that require precise control and high reliability.

[0075] Refer to Figures 1 to 5 , in some embodiments, the self-locking connecting rod 53 proposed in the embodiment of the present utility model includes a first arm 531, a second arm 532, and a transition portion 533. The first arm 531 and the second arm 532 are arranged obliquely at an obtuse angle. The transition portion 533 is arc-shaped and is connected between one end of the first arm 531 and one end of the second arm 532. The end of the first arm 531 away from the second arm 532 forms the first end of the self-locking connecting rod 53, and the end of the second arm 532 away from the first arm 531 forms the second end of the self-locking connecting rod 53. A lateral opening 530 is provided on one side of the transition portion 533.

[0076] In some embodiments, the inner wall of the lateral opening 530 is U-shaped.

[0077] In this embodiment, the basic principle of the self-locking link 53 is to utilize the structures of the first arm 531, the second arm 532, and the transition portion 533, such that when in a specific position (horizontal or vertical), the link mechanism is in a mechanical dead point state, thereby preventing accidental movement under the action of an external force.

[0078] The working process of the self-locking link 53 in the solution of this application is as follows:

[0079] Initial position (the first mechanical dead point position): As Figure 4 shown, the driven swing arm 52 is collinear with the first arm 531 of the self-locking link 53. At this time, the brake lever 100 is in the horizontal position, and the driving device 4 is started, and a driving force is applied starting from the initial collinear state (the first mechanical dead point position).

[0080] Link movement: As the driving member 41 outputs a driving force to continuously apply a driving force to the driving rotating shaft 42 towards the driving swing arm 51, it drives the self-locking link 53, thereby driving the driven swing arm 52 to start rotating, leaving the first mechanical dead point position, and moving towards the second mechanical dead point position.

[0081] Intermediate transition: During the movement of the link mechanism 5, the angle between the driven swing arm 52 and the self-locking link 53 gradually changes until it reaches the second mechanical dead point position.

[0082] Second mechanical dead point position: When the link mechanism 5 moves to the second mechanical dead point position, as Figure 5 shown, at this time, the driven swing arm 52 is collinear with the second arm 532 of the self-locking link 53, and at this time, the brake lever 100 is in the vertical position.

[0083] When the brake lever 100 descends to the position of blocking the vehicle, at this time, the first arm 531 of the self-locking link 53 is collinear with the driven swing arm 52, and at this time, it is in the first mechanical dead point position.

[0084] When the brake lever 100 rises to the position of releasing the vehicle and remains stable without rising further, at this time, the second arm 532 of the self-locking link 53 is collinear with the driven swing arm 52, and at this time, it is in the second mechanical dead point position. Even if an external force acts on the brake lever 100 or the driven rotating shaft 3, it will not cause the driven rotating shaft 3 and the self-locking link 53 to rotate, thereby realizing the self-locking function.

[0085] In some embodiments, a lateral opening 530 is provided on one side of the transition portion 533, and the inner wall is U-shaped. Its function is to allow a part of the driving rotating shaft 42 to pass through it. The U-shaped inner wall of the lateral opening 530 provides a space for rotation. The lateral opening 530 allows the driving rotating shaft 42 to rotate flexibly within a certain range, ensuring the effective transmission of the link mechanism and the precise control of the brake lever.

[0086] Refer to Figures 1 to 5In some embodiments, the active swing arm 51 provided in the embodiments of the present utility model is disposed between the self-locking connecting rod 53 and the driving member 41 in the axial direction of the active rotating shaft 42 .

[0087] Furthermore, in some embodiments, the driving member 41 includes a motor, and the driving device 4 further includes a reducer 43, which is transmission-connected between the motor and the driving shaft 42;

[0088] The active swing arm 51 is disposed between the self-locking connecting rod 53 and the reducer 43 in the axial direction of the active rotating shaft 42 .

[0089] In the above embodiment, the active swing arm 51 is located between the self-locking connecting rod 53 and the driving member 41 in the axial direction of the active rotating shaft 42 (in a further embodiment, it is located between the self-locking connecting rod 53 and the reducer 43). This arrangement optimizes the space utilization and force transmission path of the transmission structure, thereby improving the operating stability of the system and the reliability of the self-locking function.

[0090] The working principle of the above application scheme is:

[0091] Motor drive: The driving member 41 (motor) is started, and the high-speed rotation of the motor is converted into a low-speed high-torque output through the reducer 43 and transmitted to the active shaft 42.

[0092] Active swing arm drive: The active shaft 42 rotates, driving the active swing arm 51 to rotate. Since the active swing arm 51 is axially arranged between the self-locking connecting rod 53 and the reducer 43, the transmission distance of the active swing arm 51 is short, ensuring a simple and efficient force transmission path.

[0093] Transmission of connecting rod mechanism: The rotation of the active swing arm 51 is transmitted to the first end of the self-locking connecting rod 53 through its second end, and the self-locking connecting rod 53 moves accordingly. The second end of the self-locking connecting rod 53 is connected to the second end of the driven swing arm 52, thereby transmitting the movement to the driven swing arm 52. The first end of the driven swing arm 52 is fixedly connected to the driven rotating shaft 3, thereby driving the driven rotating shaft 3 to rotate, and finally realizing the lifting and lowering action of the gate rod 100.

[0094] When the gate rod 100 is in a horizontal or vertical position, the self-locking link 53 forms a collinear or nearly collinear state with the active swing arm 51 and the driven swing arm 52 due to its specific geometric design, causing the system to be in a mechanical dead point, thereby realizing the self-locking function.

[0095] The present application achieves the following effects by setting the positional relationship between the active rotating shaft 42, the self-locking connecting rod 53 and the driving member 41 of the above structure:

[0096] First, high-efficiency power transmission: The active swing arm 51 is axially located between the self-locking link 53 and the reducer 43 on the active rotating shaft 42, ensuring direct transmission of the driving force, reducing energy loss in intermediate links, and improving the transmission efficiency of the system.

[0097] Second, compact structure: This layout optimizes space utilization. The arrangement of the reducer, motor, active rotating shaft, active swing arm, and self-locking link is compact, reducing the occupied space and making the entire barrier gate system more compact and aesthetically pleasing.

[0098] Third, further, the use of the reducer 43 reduces the speed of the motor and increases the output torque, making the system operate more smoothly during operation, reducing vibration and shock, and improving the service life and reliability of the barrier gate.

[0099] Further explanation of the role of the reducer 43:

[0100] The reducer 43 converts the high-speed rotation of the motor into a low-speed high-torque output through gear transmission, thus adapting to the requirements of the barrier gate system.

[0101] The motor generates high-speed rotation and transmits it to the reducer 43 through the drive shaft. The internal gear group of the reducer 43 transmits the power, converts the high-speed rotation into a low-speed high-torque output, and transmits it to the active rotating shaft 42. The low-speed high-torque output of the active rotating shaft 42 directly drives the active swing arm 51 to achieve smooth movement of the linkage mechanism.

[0102] The reducer 43 amplifies the output torque of the motor, enabling the system to have sufficient power when driving the gate rod 100 and ensuring smooth lifting and lowering of the gate rod. The low-speed output makes the motion control of the system more precise, enabling accurate positioning and stable control of the gate rod. Through the speed reduction transmission of the reducer 43, wear caused by high-speed rotation is reduced, improving the durability and service life of the system.

[0103] In summary, in this embodiment, by reasonably arranging the active swing arm 51, self-locking link 53, and driving member 41 (the reducer 43 can be further provided in some embodiments) axially on the active rotating shaft 42, high-efficiency force transmission, a compact structural layout, a reliable self-locking function, and a smooth operating effect are achieved, thus significantly improving the overall performance and reliability of the barrier gate system.

[0104] Refer to Figure 6, in some embodiments, the active swing arm 51 proposed in the embodiments of the present utility model has a first surface and a second surface that are relatively spaced apart, and a peripheral wall surrounding the peripheries of the first surface and the second surface. The first end of the active swing arm 51 has a connection hole 510 that penetrates through the first surface and the second surface. A part of the active rotating shaft 42 is inserted into the connection hole 510. The second end of the active swing arm 51 is provided with a first hinge portion 511, and the first hinge portion 511 is used to rotatably connect to the first end of the self-locking link 53 through a hinge.

[0105] In this embodiment, through its specific structural design, the active swing arm 51 in the solution of the present application realizes the mechanical connection and motion transmission with the active rotating shaft 42 and the self-locking link 53. Specifically, the first end of the active swing arm 51 is connected to the active rotating shaft 42 through the connection hole 510, and the second end is connected to the first end of the self-locking link 53 through the first hinge portion 511. When the driving device 4 is started, the active swing arm 51 rotates under the drive of the active rotating shaft 42, transmits the motion to the self-locking link 53, thereby driving the entire link mechanism 5 to operate, and finally realizing the lifting and self-locking functions of the gate rod 100.

[0106] The working process of the active swing arm 51 in the solution of the present application is as follows:

[0107] Driving device starts: The driving member 41 starts and drives the active rotating shaft 42 to rotate through transmission connection.

[0108] Active swing arm moves: A part of the active rotating shaft 42 is inserted into the connection hole 510 of the active swing arm 51. Through the rotation of the active rotating shaft 42, the active swing arm 51 is driven to rotate synchronously.

[0109] Link mechanism transmission: The second end of the active swing arm 51 is provided with a first hinge portion 511, and the first hinge portion 511 is rotatably connected to the first end of the self-locking link 53 through a hinge. As the active swing arm 51 rotates, the first end of the self-locking link 53 also rotates accordingly, transmitting the motion to the self-locking link 53.

[0110] Self-locking link transmission: The second end of the self-locking link 53 is connected to the second end of the driven swing arm 52, thereby transmitting the motion to the driven swing arm 52. The first end of the driven swing arm 52 is fixedly connected to the driven rotating shaft 3, and the driven rotating shaft 3 rotates accordingly, thereby driving the gate rod 100 to lift.

[0111] In some embodiments, the hinge can be selected as a rotating shaft.

[0112] Refer to Figure 7, in some embodiments, the driven swing arm 52 proposed in the embodiments of the present utility model includes a cylindrical structure 521, a driven arm 522, and a second hinge portion 523. The cylindrical structure 521 is hollow, and a part of the driven rotating shaft 3 is inserted into the cylindrical structure 521. One end of the driven arm 522 is fixedly connected to the circumferential side of the cylindrical structure 521, and the second hinge portion 523 is provided at the other end of the driven arm 522. The second hinge portion 523 is used to rotatably connect to the second end of the self-locking link through a hinge.

[0113] In this embodiment, through its specific structural design, the driven swing arm 52 in the embodiments of the present utility model realizes the mechanical connection and motion transmission with the driven rotating shaft 3 and the self-locking link 53. Specifically, the driven swing arm 52 includes a cylindrical structure 521, a driven arm 522, and a second hinge portion 523. The cylindrical structure 521 is hollow, and a part of the driven rotating shaft 3 is inserted therein. One end of the driven arm 522 is fixedly connected to the circumferential side of the cylindrical structure 521, and the second hinge portion 523 is provided at the other end, which can be rotatably connected to the second end of the self-locking link 53 through a hinge. When the driving swing arm 51 drives the self-locking link 53 to move, the driven swing arm 52 rotates accordingly, thereby driving the movement of the driven rotating shaft 3 and the brake rod 100.

[0114] A part of the driven rotating shaft 3 is inserted into the cylindrical structure 521 and is rotatably connected to the mounting seat 2 to provide a rotation fulcrum. One end of the driven arm 522 is fixedly connected to the circumferential side of the cylindrical structure 521 to ensure that the driven arm 522 and the cylindrical structure 521 rotate synchronously. The second hinge portion 523 is provided at the other end of the driven arm 522 and is rotatably connected to the second end of the self-locking link 53 through a hinge.

[0115] The driving member 41 is activated to drive the driving rotating shaft 42 to rotate, and then drives the driving swing arm 51 to rotate through the connection hole 510. The rotation of the driving swing arm 51 is transmitted to the self-locking link 53 through the first hinge portion 511, causing the self-locking link 53 to move.

[0116] The first end of the self-locking link 53 is connected to the driving swing arm 51, and the second end is connected to the driven swing arm 52 through the second hinge portion 523. As the self-locking link 53 moves, the second hinge portion 523 of the driven swing arm 52 drives the driven arm 522 to rotate.

[0117] The driven arm 522 transmits the motion to the driven rotating shaft 3 through the cylindrical structure 521, causing the driven rotating shaft 3 to rotate accordingly. The other end of the driven rotating shaft 3 is connected to the brake rod 100, driving the brake rod 100 to perform a lifting action.

[0118] When the brake rod 100 is in a horizontal or vertical position, the self-locking link 53 forms a collinear or nearly collinear state with the driving swing arm 51 and the driven swing arm 52, making the system in a mechanical dead point, realizing the self-locking function and preventing accidental movement under the action of external forces.

[0119] The present application achieves the following effects by providing the driven swing arm 52 with the above structure:

[0120] Stable and reliable motion transmission: The cylindrical structure 521 and the driven arm 522 of the driven swing arm 52 ensure the rotational transmission of the driven rotating shaft 3, with a stable and reliable structure.

[0121] Efficient force transmission: The design of the driven swing arm 52 ensures the efficient transmission of the rotational torque of the driven rotating shaft 3, enabling the system to smoothly control the lifting of the gate rod 100.

[0122] Compact structure: The driven swing arm 52 has a hollow cylindrical structure 521, rationally utilizing space and maintaining the compactness and aesthetics of the system.

[0123] In summary, the driven swing arm 52 in this embodiment, through the structural design of its cylindrical structure 521, driven arm 522, and second hinge portion 523, achieves stable and reliable motion transmission, efficient force transmission, a compact structural layout, and smooth operation effects, significantly improving the overall performance and reliability of the barrier gate system. At the same time, the connection between the second hinge portion 523 and the self-locking link 53 ensures the reliability of the self-locking function and improves the safety of the system.

[0124] Referring to Figure 7 , in some embodiments, the peripheral wall of the cylindrical structure 521 proposed in the embodiment of the present utility model has a first opening 5210, and a locking hole 5211 is provided on the circumference of the cylindrical structure 521 near the first opening 5210. The locking hole 5211 is used to tighten the first opening 5210 to clamp the driven rotating shaft 3.

[0125] In this embodiment, the design of the cylindrical structure 521 includes a first opening 5210 and a locking hole 5211 near this opening. This design allows the cylindrical structure 521 to have a certain degree of flexibility when installing or adjusting the driven rotating shaft 3. Through the tightening action of the locking hole 5211, the first opening 5210 of the cylindrical structure 521 can clamp the driven rotating shaft 3, thereby achieving a firm fixing effect.

[0126] The driven rotating shaft 3 passes through the first opening 5210 of the cylindrical structure 521. Adjust the position of the driven rotating shaft 3 to ensure its proper positioning within the cylindrical structure 521. Use a locking screw or other fastener to pass through the locking hole 5211. Tighten the locking hole 5211 so that the peripheral wall of the cylindrical structure 521 tightens at the first opening 5210, thereby clamping the driven rotating shaft 3.

[0127] After locking, the driven rotating shaft 3 is firmly fixed within the cylindrical structure 521, preventing it from displacing or loosening during operation.

[0128] As needed, the fastener of the locking hole 5211 can be loosened to adjust the driven rotating shaft 3, and then locked again to ensure the best transmission effect.

[0129] In summary, through the design of the first opening 5210 and the locking hole 5211 in the cylindrical structure 521 of this embodiment, the stable fixation, convenient installation and adjustment, wear reduction and transmission efficiency improvement of the driven rotating shaft 3 are realized, thereby significantly enhancing the overall performance and reliability of the barrier gate system. This design simplifies the installation and maintenance processes and improves the stability and service life of the system.

[0130] Referring to Figure 1 and Figure 2 , in some embodiments, the number of the mounting seats 2 proposed in the embodiments of the present invention is two, the two mounting seats 2 are arranged opposite to each other at intervals, and the driven swing arm 52 is located between the two mounting seats 2;

[0131] In some embodiments, the barrier gate core further includes a support 6, the support 6 is arranged on the second surface of the mounting member 1, the support 6, the self-locking connecting rod, the driving swing arm 51 and the driving member 41 are arranged in sequence along the horizontal direction, and one end of the driving rotating shaft 42 facing away from the driving member 41 is rotatably connected to the support 6.

[0132] In this embodiment, the purpose of arranging the two mounting seats 2 is to provide a stable and reliable support structure for the driven rotating shaft 3 to ensure the smooth operation of the driven rotating shaft 3. Through the arrangement of the two mounting seats 2, the loads of the driven rotating shaft 3 and the gate rod 100 can be effectively dispersed and borne, vibrations and offsets in the system can be reduced, and the overall stability and precision can be improved.

[0133] In some embodiments, the rotational connection between the mounting seat 2 and the driven rotating shaft 3 is usually achieved by mechanical elements such as bearings or bushings. It can provide low-friction rotational movement while ensuring the stable operation of the driven rotating shaft 3 within the mounting seat 2. The bearing or bushing provides rotational support between the driven rotating shaft and the mounting seat, allowing the driven rotating shaft to rotate freely when subjected to a driving force while maintaining its position stability.

[0134] The support 6 is fixed on the second surface of the mounting member 1, on the opposite side of the driving member 41. After one end of the driving rotating shaft 42 passes through the self-locking connecting rod and the driving swing arm 51, the end facing away from the driving member 41 is connected to the support 6 through a rotational connection device such as a bearing or a bushing.

[0135] The support 6 serves as a support point, sharing part of the load of the driving rotating shaft 42 and ensuring its stability during rotation. With the support of the support 6, the driving rotating shaft 42 can remain stable when rotating under the action of the driving member 41, reducing axial and radial movements.

[0136] The support 6 helps to disperse the torque and load transmitted from the driving member 41 to the driving rotating shaft 42, reducing the burden on the driving member 41. By reasonably dispersing the force, the support 6 reduces the stress concentration in the system and the risk of wear and damage.

[0137] Furthermore, the present utility model provides a barrier gate, which includes a chassis, an electronic control device, a gate rod 100, and the barrier gate core as described in the foregoing embodiments. The electronic control device and the barrier gate core are arranged in the chassis. The gate rod 100 is connected to the driven rotating shaft 3 of the barrier gate core. The electronic control device is electrically connected to the barrier gate core to control the driving device 4 of the barrier gate core to drive the driven rotating shaft 3 to drive the gate rod 100 to move. When the driving device 4 drives the driven rotating shaft 3 to drive the gate rod 100 to move to the horizontal or vertical state, the link mechanism is respectively in the first mechanical dead point position and the second mechanical dead point position, thereby preventing the undesirable phenomenon that the gate rod 100 is lifted or lowered under the action of an external force.
