Abstract
Description
Technical Field
[0001] This utility model relates to the field of turnstile technology, specifically to a self-locking gate mechanism. Background Technology
[0002] Parking barrier gates are common equipment in parking lot entrance and exit fee management. They create lane barriers by using a barrier arm, and the barrier arm can be raised and lowered through license plate recognition and other control methods. With societal development and the continuous increase in global vehicles, the demand for parking barrier gates at various entrances and exits is constantly increasing, requiring them to meet the needs of more diverse scenarios. During operation, parking barrier gates may encounter problems such as power outages or malfunctions in their control systems, preventing the barrier arm from raising and lowering properly and affecting normal passage. Therefore, a parking barrier mechanism that allows manual raising and lowering of the barrier arm in emergency situations is needed. Utility Model Content
[0003] Based on this, the present invention provides a clutch-type self-locking barrier gate mechanism to solve the technical problem that existing barrier gate mechanisms are inconvenient to manually control the raising and lowering of the barrier arm (gate arm) when there is a power outage or malfunction.
[0004] To achieve the above objectives, this utility model provides a clutch-type self-locking barrier gate mechanism, which includes:
[0005] Movement mounting plate;
[0006] The main shaft includes a rotary handle, an A-shaft section, a coupling, and a B-shaft section arranged sequentially along the same axis. The A-shaft section and the B-shaft section are rotatably mounted on the mechanism mounting plate via bearing seats. The ends of the A-shaft section and the B-shaft section that are close to each other are respectively provided with shaft heads that cooperate with the coupling. The coupling locks or unlocks the shaft heads of the A-shaft section and the B-shaft section by axial movement. The rotary handle is connected to the coupling via a locking shaft that axially passes through the A-shaft section. The rotary handle is used to drive the coupling to move axially via the locking shaft.
[0007] The gate arm is fixedly connected to the B-axis segment and extends radially along the B-axis segment;
[0008] A power transmission mechanism, connected to the A-shaft segment to drive the A-shaft segment to rotate; and
[0009] The balancing mechanism includes a balance arm and a tension spring. The balance arm is fixedly connected to the B-axis segment and extends radially along the B-axis segment. The tension spring is connected to the balance arm. During the gate arm raising process, the tension spring provides a positive force for the rotation of the B-axis segment, and during the gate arm lowering process, the tension spring provides a reverse force for the rotation of the B-axis segment.
[0010] As a further preferred technical solution of this utility model, the front end of the locking shaft passes through the coupling and is provided with an external threaded shaft, and the shaft head of the B shaft section is provided with an internal threaded hole. When the locking shaft drives the coupling shaft to move toward the B shaft section and locks the shaft heads of the A shaft section and the B shaft section through the coupling, the external threaded shaft and the internal threaded hole are threadedly connected.
[0011] As a further preferred technical solution of this utility model, a return spring is provided inside the shaft head of the B shaft section, and the coupling elastically abuts against the return spring.
[0012] As a further preferred technical solution of this utility model, the movement mounting plate is connected to a fixed bracket for support, one end of the tension spring away from the movement mounting plate is fixed on the fixed bracket, and the position of the tension spring on the fixed bracket relative to the installation distance of the movement mounting plate is adjustable.
[0013] As a further preferred technical solution of this utility model, there are two tension springs, which are arranged in parallel.
[0014] As a further preferred technical solution of this utility model, a connecting plate is provided at the end of the B-axis segment away from the A-axis segment, and the gate arm is fixed on the connecting plate.
[0015] As a further preferred technical solution of this utility model, the power transmission mechanism includes a motor, a small swing arm, and a rocker arm. The rocker arm is fixedly connected to the A-axis segment and extends radially along the A-axis segment. A strip-shaped groove is provided on the rocker arm. One end of the small swing arm is fixedly connected to the motor shaft of the motor, and the other end of the small swing arm is provided with a sliding shaft located in the strip-shaped groove. When the motor is running, the small swing arm drives the sliding shaft to slide in the strip-shaped groove, thereby driving the rocker arm to rotate around the A-axis segment, and thus driving the A-axis segment to rotate.
[0016] As a further preferred technical solution of this utility model, the motor is a servo motor.
[0017] The clutch-type self-locking barrier gate mechanism of this utility model, by adopting the above-mentioned technical solution, can achieve the following beneficial effects:
[0018] 1) The clutch self-locking barrier gate mechanism of this utility model uses a tension spring to provide action and reaction forces during the raising / lowering of the barrier arm, which ensures the smooth operation of the barrier arm, thereby increasing its service life and reducing maintenance costs; moreover, the smooth operation reduces operating noise, thus improving the user experience.
[0019] 2) The clutch self-locking barrier gate mechanism of this utility model has a segmented structure for its main shaft. Its A-shaft segment and B-shaft segment are flexibly connected by a coupling, which can realize the locking and unlocking of the A-shaft segment and B-shaft segment. In the event of mechanism failure or power failure, the barrier can be manually raised and lowered by manual unlocking.
[0020] 3) When the clutch self-locking barrier gate mechanism of this utility model is operating normally, the tension spring provides force to assist in the lifting process, and the gate arm rises and falls quickly, thereby ensuring the passage efficiency of the barrier.

[0028] like Figures 1 to 3As shown, this utility model provides a clutch-type self-locking barrier gate mechanism, comprising:
[0029] Fixed bracket;
[0030] The movement mounting plate 7 is fixedly mounted on the top of the fixed bracket;
[0031] The main shaft includes a rotating handle 1, an A-shaft section 4, a coupling 5, and a B-shaft section 12 arranged sequentially along the same axis. The A-shaft section 4 and the B-shaft section 12 are rotatably mounted on the mechanism mounting plate 7 via bearing seats 6. The ends of the A-shaft section 4 and the B-shaft section 12 that are close to each other are respectively provided with shaft heads that cooperate with the coupling 5. The coupling 5 locks or unlocks the shaft heads of the A-shaft section 4 and the B-shaft section 12 by axial movement. The rotating handle 1 is connected to the coupling 5 by a locking shaft 3 that axially passes through the A-shaft section 4. The rotating handle 1 is used to drive the coupling 5 to move axially via the locking shaft 3.
[0032] The gate arm 16 is fixedly connected to the connecting plate at the end of the B-shaft segment 12 and extends radially along the B-shaft segment 12 so as to rotate with the B-shaft segment 12.
[0033] The power transmission mechanism includes a motor 14, a small swing arm 10, and a rocker arm 2. The rocker arm 2 is fixedly connected to the A-axis segment 4 and extends radially along the A-axis segment 4. A strip-shaped groove is formed on the rocker arm 2. The motor 14 is fixedly connected to the mechanism mounting plate 7 via a motor bracket plate 13. One end of the small swing arm 10 is fixedly connected to the motor shaft 15 of the motor 14, and the other end of the small swing arm 10 is provided with a sliding shaft 8 located within the strip-shaped groove. When the motor 14 operates, the small swing arm 10 drives the sliding shaft 8 to slide within the strip-shaped groove, thereby causing the rocker arm 2 to rotate about the A-axis segment 4, and thus causing the A-axis segment 4 to rotate.
[0034] The balancing mechanism includes a balance arm 9 and a tension spring 17. The balance arm 9 is fixedly connected to the B-axis segment 12 and extends radially along the B-axis segment 12. The tension spring 17 is connected to the balance arm 9, and one end of the tension spring 17 away from the main shaft is fixed to a fixed bracket. Two tension springs 17 are arranged in parallel. During the raising of the gate arm 16, the tension spring 17 provides a positive force for the rotation of the B-axis segment 12, and during the lowering of the gate arm 16, the tension spring 17 provides a reverse force for the rotation of the B-axis segment 12.
[0035] To better lock and connect shaft A section 4 and shaft B section 12 via coupling 5 using locking shaft 3, the front end of locking shaft 3 passes through coupling 5 and is provided with an external thread. The shaft head of shaft B section 12 is provided with an internal thread hole. When locking shaft 3 drives coupling 5 to move towards shaft B section 12 and locks the shaft heads of shaft A section 4 and shaft B section 12 through coupling 5, the external thread shaft and the internal thread hole are threadedly engaged. Furthermore, to better release coupling 5 from the shaft head of shaft B section 12 when unlocking shaft A section 4 and shaft B section 12, a return spring 11 is provided inside the shaft head of shaft B section 12, and coupling 5 elastically abuts against the return spring 11.
[0036] In normal use, the locking shaft 3 drives the coupling 5 to be fixed inside the shaft head of section B 12. At this time, section A 4 and section B 12 are locked together by the coupling 5. Section A 4 and section B 12 can rotate synchronously, which can drive the gate arm 16 to move through the main shaft via the power transmission mechanism, thus raising or lowering the arm. When the gate mechanism malfunctions or there is a power outage, the gate arm 16 cannot be moved by the power transmission mechanism. In this case, the gate arm 16 can be raised or lowered manually. The specific operation is as follows: first, turn the rotating handle 1 to make the locking shaft 3 drive the coupling 5 towards section A 4, thus disengaging the coupling 5 from the shaft head of section B 12, thereby unlocking section A 4 and section B 12. At this time, section B 12 can rotate independently, and the gate arm 16 can be easily pushed or pulled manually to raise or lower the arm. It should be noted that the coupling 5 of this utility model is also called a coupling joint, which is a conventional mechanical engineering device. In the process of transmitting motion and power, the coupling 5 is used to connect two separate shafts to achieve rotation together. It is a conventional technology. The specific structure of the coupling 5 and the shaft head will not be described in detail here.
[0037] In order to achieve rapid arm raising, the tension spring 17 is configured via the balance arm 9 to operate when the gate arm 16 is in the lowered state (e.g., Figure 2 When stretched to its maximum, in the lever-raised state (e.g.) Figure 3 The tension generated is minimal when the lever 16 is raised. Therefore, during the raising process of the lever 16, the elastic tension provided by the tension spring 17 assists in the rotation of the B-axis segment 12, thereby increasing the raising speed. Conversely, during the lowering process, the tension spring 17 provides a reaction force, ensuring smooth movement and effectively reducing mechanical impact, thus preventing equipment damage. Furthermore, the tension spring 17 can perform its corresponding functions during both normal electrically controlled and manual lever raising and lowering processes.
[0038] Although specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention. The scope of protection of the present invention is defined only by the appended claims.
