Description

Technical Field

[0001] This utility model relates to the field of turnstile equipment technology, specifically to a small three-roller turnstile core and aluminum disc connection and positioning device. Background Technology

[0002] Turnstiles are access control devices used for orderly passage of people. They are often linked with facial recognition, access control or switches, and feature fast passage, high reliability, strong adaptability and easy maintenance. They are widely used in scenic spots, residential areas, stations, cinemas and other scenarios.

[0003] The shortcomings of existing technology: 1. Risk of loosening and falling off the connection: The existing connection between the movement and the aluminum disc is prone to loosening under excessive rotation and repeated impact from the positioning arm. Long-term use may cause the three fastening screws (such as M10-55mm) at the aluminum disc to loosen or even fall off, resulting in malfunction and loss to the user.

[0004] 2. Inherent deficiencies in positioning method: The traditional "planar step" positioning method has poor resistance to circumferential rotation and is difficult to effectively suppress relative rotation along the circumferential direction.

[0005] 3. Tightening alone does not provide effective positioning: Existing solutions often use three screws for clamping, but lack a matching geometric positioning structure, making it difficult to form a reliable anti-rotation positioning even after tightening.

[0006] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0007] To address the problems existing in the prior art, this utility model provides a small tripod turnstile mechanism and aluminum disc connection and positioning device.

[0008] To achieve the above objectives, the specific solution of this utility model is as follows: This utility model provides a small tripod turnstile core and aluminum disc connection and positioning device, including: The movement includes a spindle, with a cam mounted on one end and a chuck mounted on the other. The aluminum disc gate arm includes an aluminum disc and three rollers mounted on the aluminum disc, the aluminum disc being mounted on a cam; The control section, electrically connected to the movement section, is used to control the locking and unlocking of the movement. The aluminum disc is mounted on the cam by three bolts.

[0009] Furthermore, the aluminum disc is provided with three first protrusions, and the cam is provided with a first groove at a corresponding position; The first boss is positioned and fixed in the first groove; The three bolts are spaced 120 degrees from each other. Both the first boss and the first groove are provided with screw holes, and the bolts pass through the screw holes.

[0010] Further, the main shaft is installed through the bottom plate. The control part includes a main board, and the main board is installed on the bottom plate.

[0011] Further, the bottom plate is a plate-like structure with a U-shaped cross-section.

[0012] Further, the chuck is circumferentially and evenly provided with three card slots, and the three card slots are spaced 120 degrees from each other. One card arm is provided on each side of the chuck, and an electromagnet is correspondingly provided beside each card arm. The electromagnet has an output shaft, and a first spring is sleeved on the output shaft. The output shaft of the electromagnet is fixedly connected to the card arm. When the electromagnet is powered off, the first spring elastically resets and drives the output shaft and the card arm to push forward in the direction close to the chuck, and the card arm is clamped into the card slot of the chuck, and the movement mechanism is locked. When the electromagnet is powered on, the electromagnet generates suction force to cause the output shaft to contract inward, and the output shaft drives the card arm to retract in the direction away from the chuck, and the card arm withdraws from the card slot, and the chuck can rotate freely, thereby driving the main shaft, the cam and the aluminum disc to rotate synchronously, and finally realizing the rotation of the roller rod.

[0013] Further, a reset arm is further provided beside the cam. One end of the reset arm is rotatably installed on the bottom plate, the other end of the reset arm is connected to a tension spring, and the other end of the tension spring is installed on the bottom plate. A first bearing is also fixedly installed on the reset arm. Under the continuous pulling force of the tension spring, the first bearing always abuts against the outer peripheral wall of the cam.

[0014] Further, the roller rod is detachably installed on the aluminum disc through a docking structure. The docking structure includes a first lock head, a second lock head and a torsion spring. The first lock head is rotatably connected to the aluminum disc through a first rotating shaft. The roller rod is fixedly installed at one end of the first lock head. A second boss is provided at the other end of the first lock head, and the second boss is adapted to one end of the second lock head. The second lock head is rotatably connected to the aluminum disc through a second rotating shaft. The torsion spring is sleeved on the second rotating shaft, and one end of the torsion spring abuts against the aluminum disc, and the other end of the torsion spring abuts against the second lock head. The elastic force of the torsion spring always presses one end of the second lock head against the second boss of the first lock head to realize the locking of the first lock head and the second lock head.

[0015] Further, a rod withdrawing mechanism is also fixedly installed on the bottom plate. The lever retraction mechanism includes a lever retraction power component (such as an electromagnet, a cylinder, etc.) and a baffle plate, wherein the baffle plate is fixedly installed on the output shaft of the lever retraction power component; When the aluminum disc drives the roller to rotate to the position corresponding to the retraction mechanism, the retraction power component pushes the baffle to move closer to the second locking head through the output shaft. The baffle presses down on the end of the second locking head away from the torsion spring. At this time, the end of the second locking head pressed by the torsion spring overcomes the spring force and springs upward, thus disengaging from the second boss of the first locking head. The first locking head can then rotate freely around the first rotating shaft to remove the roller from the aluminum disc.

[0016] The technical solution of this utility model has the following beneficial effects: 1. Miniaturized chassis allows for more flexible and aesthetically pleasing chassis designs: With a smaller chassis size, the chassis can be modified in various ways, resulting in a more beautiful appearance and improved quality.

[0017] 2. Significantly reduced operating noise: After structural optimization, the overall noise level of the machine has been greatly reduced, resulting in a better travel experience.

[0018] 3. Smoother operation and less wear: Avoids excessive friction when the rotating rod rotates, making the rotation smoother and reducing the wear of parts.

[0019] 4. No loosening during long-term use: After long-term testing, the aluminum disc and the movement remain firmly connected, achieving the expected anti-loosening effect. Attached Figure Description

[0034] The principle of this utility model is as follows: Mechanical transmission chain The control unit issues a command → the electromagnet 11 actuates → the chuck arm 10 releases / locks the chuck 3 → the main shaft 1, cam 2, and aluminum disc 4 rotate or remain stationary as a whole → the three rollers 5 simultaneously complete the release or blocking.

[0035] Lock / Unlock Actions Normal state of power failure: When the electromagnet 11 loses power, the output shaft extends outward under the action of the first spring 12, pushing the clamping arm 10 into the chuck 3 and the 120° evenly distributed clamping slots 9. The mechanism is mechanically locked, and the roller 5 cannot rotate.

[0036] Power-on release: When the electromagnet 11 is energized, it generates a suction force, the output shaft compresses the first spring 12 and retracts, the chuck arm 10 exits the chuck slot 9, and the chuck 3 is unlocked; the external force pushes the roller 5 to drive the aluminum disc 4, cam 2 and main shaft 1 to rotate together by 60° or 120°, realizing single release.

[0037] Automatic Reset After passage is completed, cam 2 continues to rotate with aluminum disc 4; the outer peripheral wall of cam 2 presses the first bearing 15 on reset arm 13, causing reset arm 13 to swing around the fulcrum of base plate 7 and stretch tension spring 14; when the external force disappears, tension spring 14 pulls back reset arm 13, first bearing 15 pushes cam 2 to rotate in the opposite direction, and roller 5 automatically returns to the blocking zero position, waiting for the next unlocking.

[0038] High-precision positioning and quick assembly / disassembly The aluminum disc 4 and the cam 2 are positioned by a "three-protrusion-three-groove" circumferential positioning, and the 120° evenly distributed bolts are tightened at one time to ensure that the repeated installation angle accuracy is ≤±0.2°.

[0039] The roller 5 and the aluminum disc 4 are connected by a lock-torsion spring 18 quick-release structure. Locking – Torsion spring 18 presses the second lock head 17 against the second boss 20 of the first lock head 16, and roller 5 is fixed; Disassembly – The retraction power component 22 pushes the baffle 23 down to press down the tail end of the second lock head 17. The front end of the second lock head 17 lifts up and disengages from the second boss 20. The first lock head 16, together with the roller 5, can rotate outward around the first rotating shaft 19, achieving tool-free, second-level disassembly of the rod.

[0040] Modular integration The Z-shaped base plate 7 integrates the main shaft 1, control motherboard 8, electromagnet 11, reset arm 13, and retraction mechanism into an independent core module. The whole module can be put into a small gate box for use. During maintenance, the entire core can be pulled out. A single person can complete the replacement of roller 5 or the repair of the core within 5 minutes.
