Abstract
Description
Technical Field
[0001] This utility model relates to the field of gate technology, and in particular to a vertical rod type three-roller gate turntable. Background Technology
[0002] As is well known, a turnstile is a channel blocking device (channel management equipment) mainly used in urban rail transit management and fare collection systems to manage pedestrian flow and regulate pedestrian access. Therefore, it creates paid and non-paid areas. Its most basic and core function is to allow only one person to pass through at a time, and it can be used at entrances in various toll collection and access control situations. Structurally, it mainly consists of a main unit and a turntable for blocking people from passing through. The turntable is connected to the mechanism inside the main unit, and its rotation controls the passage of one person at a time.
[0003] Existing turnstiles use a three-roller turnstile to control single-person passage. This consists of three rollers at a 120° angle, with each roller's centerline forming a +45° angle with the movement's centerline. The rotation of the turnstile restricts passage to one person at a time. However, in emergencies, such as sudden incidents requiring urgent evacuation, the outward extension of the rollers can obstruct passage. Current solutions address this by adding an unlocking mechanism to each roller. Therefore, with three rollers, three unlocking mechanisms are needed, each requiring both unlocking and locking functions. Given the limited space available at the turnstile location, this design becomes inconvenient and increases costs.
[0004] Therefore, to address this defect, it is necessary to provide a three-roller turntable with a simpler structure. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vertical rod type tripod turntable with a simpler structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A vertical rod type tripod turnstile includes a turntable, a single electromagnet, and three rollers. The turntable is provided with a threaded connecting post for connection with the turnstile mechanism. Each roller is provided with a shaft at one end, and the shaft and roller form an obtuse angle. The shaft is connected to the turntable through a bearing or bushing. The end of the shaft passes into the turntable and locks a cylindrical block. A locking port is provided on the side of the cylindrical block. A vertical rod is provided on the side of the turntable located on the cylindrical block. A locking block is shaft-connected to the vertical rod. The locking block is "V" shaped. A cylindrical locking rod is provided at one end of the locking block, and a trigger plate is formed at the other end of the locking block. A torsion spring or spring sheet is provided between the locking block and the vertical rod.
[0008] Under the action of the torsion spring or spring sheet, the locking rod is always in contact with the side of the cylindrical block, the electromagnet is fixedly installed on the gate, and the telescopic head of the electromagnet is placed at the turntable after it extends and coincides with the movement trajectory of the trigger piece.
[0009] Preferably, both ends of the trigger plate are provided with sloping edges, and the telescopic head of the electromagnet is equipped with a rotatable roller.
[0010] Preferably, the locking rod is rotatably mounted on the locking block.
[0011] Because of the above solution, this utility model only sets up a locking block at each roller shaft that can automatically lock the rotation of the roller shaft, and only uses one electromagnet to control the unlocking of the entire locking block, so that the drooping of the roller shaft is completed in a very simple structure. The structure is simple and very convenient for structural layout on the turntable. Attached Figure Description

[0018] like Figures 1 to 3 As shown, this embodiment provides a vertical rod type tripod turnstile, including a turntable 1, a single electromagnet 2, and three rollers 3. The turntable 1 is provided with a threaded connecting post 4 for connecting with the turnstile mechanism. Each roller 3 has a shaft 5 at one end, and the shaft 5 and the roller 3 form an obtuse angle. The shaft 5 is connected to the turntable 1 through a bearing or bushing. The end of the shaft 5 passes into the turntable 1 and locks a cylindrical block 6. A locking slot 7 is provided on the side of the cylindrical block 6. A vertical rod 8 is provided on the side of the turntable 1 located on the cylindrical block 6. The vertical rod 8 is shaft-connected to a locking block 9. The locking block 9 is "V" shaped. One end of the locking block 9 is provided with a cylindrical locking rod 10, and the other end of the locking block 9 forms a trigger plate 11. A torsion spring or spring plate 12 is provided between the locking block 9 and the vertical rod 8.
[0019] Under the action of the torsion spring or spring plate 12, the locking rod 10 is always in contact with the side of the cylindrical block 6, the electromagnet 2 is fixedly installed on the gate, and the telescopic head of the electromagnet 2 is placed at the turntable 1 after it extends and coincides with the moving trajectory of the trigger plate 11.
[0020] In this embodiment, only one locking block 9 is set at each roller 3 to automatically lock the rotation of the roller 3. The unlocking of the entire locking block 9 is controlled by only one electromagnet 2, so that the drooping of the roller 3 is completed in a very simple structure. The structure is simple and very convenient for structural layout on the turntable 1.
[0021] In actual operation, when it needs to be used as a gate, the telescopic head of the electromagnet 2 is in the retracted state. When the locking rod 10 of the locking block 9 is not embedded in the locking port 7, the rollers 3 all hang downwards due to gravity. As the turntable 1 moves, combined with the gravity of the rollers 3, the cylindrical block 6 will rotate relative to the turntable 1. When the locking port 7 and the locking rod 10 are just aligned, the rotation of the cylindrical block 6 will be locked, thereby locking the rollers 3 at an angle. As rotation continues, all three rollers 3 will be locked one by one to meet the gate's blocking requirements. When it is necessary to unlock, the telescopic head of electromagnet 2 simply extends and is positioned to contact the trigger plate 11. As the turntable 1 rotates, when the trigger plate 11 on the locking block 9 contacts the telescopic head of electromagnet 2, it will press the trigger plate 11, causing the torsion spring or spring 12 to deform, causing the locking rod 10 to disengage from the locking port 7. In order for the roller 3 to rotate when unlocked, the telescopic head of electromagnet 2 is positioned diagonally upward. Therefore, under the action of gravity, the roller 3 will rotate, and the locking port 7 and the locking rod 10 will be misaligned. After misalignment, the roller 3 can be in a drooping state, thus no longer obstructing the gate.
[0022] Furthermore, in order to enable the electromagnet 2 to better control the trigger plate 11, both ends of the trigger plate 11 in this embodiment are provided with ramp edges 13 (both sides are provided, mainly to ensure that unlocking can be completed in both forward and reverse rotation). The telescopic head of the electromagnet 2 is equipped with a rotatable roller 14. When the telescopic head of the electromagnet 2 extends and the turntable 1 rotates, the trigger plate 11 can contact the roller 14 by relying on the ramp edges 13. The rotatable design of the roller 14 itself allows it to rotate upon contact, thereby avoiding jamming.
[0023] Furthermore, because the torsion spring or spring sheet 12 will keep the locking rod 10 pressing against the cylindrical block 6, thus avoiding reducing the friction between the two, the locking rod 10 in this embodiment can be rotatably installed on the locking block 9. In this way, when the roller 3 is released from the lock, the rotation of the roller 3 will be smoother, that is, the drooping will be smoother, and there will be no jamming.
[0024] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
