Description

Technical Field

[0001] This utility model relates to the field of gate technology, and in particular to an automatic locking rotary gate mechanism. 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 and ticketing 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 paid and access control situations.

[0003] For turnstiles, the most crucial component is the locking mechanism. Currently, existing turnstile locking mechanisms use a single electromagnet to control a single latch. When locking is required, the latch engages with the tooth groove. However, to ensure the rigidity of the tooth protrusion, it is designed to be relatively wide, primarily to prevent breakage due to insufficient rigidity. This design sometimes causes the latch to only touch the tooth tip and not immediately engage in the groove, requiring a slight rotation to lock. This explains why turnstiles can sometimes rotate a certain angle after locking, a performance flaw, especially for heavy-duty turnstiles.

[0004] Therefore, it is necessary to optimize the existing gate locking mechanism. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic locking turntable mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic locking and rotating turnstile mechanism includes a base plate and a motor fixedly mounted on the base plate. A rotating rod is mounted on the base plate via bearings. One end of the rotating rod is positioned on one end face of the base plate and connected to the gate arm of the turnstile. A locking disc is provided at the other end of the rotating rod. The surface of the locking disc is provided with first bevel teeth. The output of the motor is connected to a rotating shaft via a coupling. The rotating shaft is mounted on the base plate via bearings. The end of the rotating shaft is provided with a second bevel tooth that meshes with the first bevel tooth. The side of the locking disc is provided with protruding teeth, and grooves are formed between the protruding teeth. An electromagnet is provided on the side of the base plate near the locking disc. The electromagnet is a bidirectional electromagnet, with a first locking rod and a second locking rod connected by a shaft. The armature at one end of the electromagnet is connected to the first locking rod, and the armature at the other end of the electromagnet is connected to the second locking rod. Each armature of the electromagnet is fitted with a corresponding spring, and the springs on different armatures respectively abut against the first locking rod and the second locking rod. A limit block is provided on the armature of the electromagnet at the other end face opposite to the first locking rod and the second locking rod. The other end of the first locking rod and the second locking rod is provided with a locking pin that can be embedded in a tooth groove. Under the action of the spring, the locking pin always tends to be embedded in the tooth groove.

[0008] Specifically, when the locking disc moves, whenever the groove on the locking disc is aligned with the locking pin on the first locking rod, the locking pin on the second locking rod is aligned with the protruding tooth on the locking disc, and whenever the protruding tooth on the locking disc is aligned with the locking pin on the first locking rod, the locking pin on the second locking rod is aligned with the groove on the locking disc.

[0009] Preferably, the armature of the electromagnet is provided with an unlocking rod, the base plate is provided with a rotary lock, the lock cylinder of the rotary lock extends to the unlocking rod and is provided with two protrusions, and the rod body of the unlocking rod is placed between the two protrusions.

[0010] Preferably, a protective cover is also provided on the substrate, which covers the locking disc.

[0011] Preferably, one end of the rotating rod is connected to the protective cover via a bearing.

[0012] Preferably, the end of the rotating rod is placed outside the protective cover and is provided with a trigger plate, and the protective cover is provided with a photoelectric switch adapted to the trigger plate.

[0013] By adopting the above-mentioned solution, this utility model uses a single electromagnet with bidirectional movement to connect the first locking rod and the second locking rod, automatically realizing that the locking pins of the first locking rod and the second locking rod move towards the locking disc synchronously, and automatically completing the locking. At the same time, by setting the tooth protrusion and tooth groove of the first locking rod and the second locking rod to be staggered, it can be ensured that one of the locking pins can be quickly inserted into the tooth groove during locking, so as to complete the quick locking of the gate, without rotating a certain distance after issuing the locking command.

[0020] like Figures 1 to 3 As shown, this embodiment provides an automatic locking and rotating turnstile mechanism, including a base plate 1 and a motor 2 fixedly mounted on the base plate 1. A rotating rod 3 is mounted on the base plate 1 via bearings. One end of the rotating rod 3 is placed on one end face of the base plate 1 and connected to the gate arm 100 of the turnstile. A locking disc 4 is provided at the other end of the rotating rod 3. The surface of the locking disc 4 is provided with first bevel teeth 5. The output of the motor 2 is connected to a rotating shaft 6 via a coupling. The rotating shaft 6 is mounted on the base plate 1 via bearings. The end of the rotating shaft 6 is provided with a second bevel tooth 7 that meshes with the first bevel tooth 5. The side of the locking disc 4 is provided with protruding teeth 8, and grooves 9 are formed between the protruding teeth 8. An electromagnet 10 and an electromagnet are provided on the side of the base plate 1 near the locking disc 4. A first locking rod 11 and a second locking rod 12, which can be rotated, are connected by a shaft. The electromagnet 10 is a bidirectional electromagnet. The armature at one end of the electromagnet 10 is connected to the first locking rod 11 through the shaft, and the armature at the other end of the electromagnet 10 is connected to the second locking rod 12 through the shaft. Each armature of the electromagnet 10 is fitted with a corresponding spring 13. The springs 13 on different armatures respectively abut against the first locking rod 11 and the second locking rod 12. A limit block 14 is provided on the armature of the electromagnet 10 at the other end face of the first locking rod 11 and the second locking rod 12. The other end of the first locking rod 11 and the second locking rod 12 is provided with a locking post 15 that can be embedded in the tooth groove. Under the action of the spring 13, the locking post 15 always tends to be embedded in the tooth groove 9.

[0021] When the locking disc 4 moves, whenever the tooth groove on the locking disc 4 is aligned with the locking pin on the first locking rod 11, the locking pin 15 on the second locking rod 12 is aligned with the protruding tooth 8 on the locking disc 4, and whenever the protruding tooth 8 on the locking disc 4 is aligned with the locking pin 15 on the first locking rod 11, the locking pin 15 on the second locking rod 12 is aligned with the tooth groove 9 on the locking disc 4.

[0022] In this embodiment, a single electromagnet with bidirectional movement is used to connect the first locking rod 11 and the second locking rod 12. This automatically enables the locking pins 15 of the first locking rod 11 and the second locking rod 12 to move towards the locking disc 4 simultaneously, thus automatically completing the locking. At the same time, by staggering the tooth protrusion 8 and tooth groove 9 of the first locking rod 11 and the second locking rod 12, it is ensured that one of the locking pins 15 can quickly insert into the tooth groove 9 during locking, thereby completing the rapid locking of the gate without rotating a certain distance after issuing the locking command.

[0023] In actual operation, when locking is required, the electromagnet 10 is in a de-energized state. In this case, the spring 13 pushes the first locking rod 11 and the second locking rod 12, so that the other ends of the first locking rod 11 and the second locking rod 12 press against the locking disc 4. Therefore, because the first locking rod 11 and the second locking rod 12 are in a staggered state when inserted into the tooth groove 9, only one locking rod's locking pin 15 will be inserted into the tooth groove 9, thereby ensuring rapid automatic locking, that is, suppressing the rotation of the locking disc 4. After the locking disc 4 is stopped from rotating, because it is integrally connected with the rotating rod 3, the gate rod 100 will also stop rotating, thus achieving the locking effect. When unlocking is required, electromagnet 10 is energized, and the armature pushes the first locking rod 11 and the second locking rod 12 to move in another direction. Spring 13 is compressed, causing the locking pins 15 on the first locking rod 11 and the second locking rod 12 to move away from the locking disc 4, thus releasing the entire locking state. At this time, the motor works, using the second bevel gear 7 on the rotating shaft 6 to drive the first bevel gear 5 to rotate. The first bevel gear 5 is connected to the locking disc 4, so the locking disc 4 also rotates. When electromagnet 10 is de-energized, the entire system returns to the locked state. It should be noted that, depending on the scenario design, the system can lock when electromagnet 10 is de-energized and unlock when it is energized, or vice versa. This substitution only requires changing the position of spring 13 and the installation direction of electromagnet 10.

[0024] Furthermore, to cope with emergencies where automatic unlocking is not possible, the armature of the electromagnet 10 in this embodiment is provided with an unlocking rod 16, and a rotary latch 17 is provided on the base plate 1. The lock cylinder of the rotary latch 17 extends to the unlocking rod 16 and is provided with two protrusions 18. The rod body of the unlocking rod 16 is placed between the two protrusions 18. When the rotary latch 17 is rotated in the unlocking direction, the protrusions 18 will drive the unlocking rod 16 to move, thereby pulling the armature of the electromagnet 10 to move along the unlocking direction. In this way, manual unlocking can be performed in an emergency.

[0025] Furthermore, to prevent debris from entering the locking disc 4, which could cause jamming, a protective cover 19 is also provided on the base plate 1 in this embodiment. The protective cover 19 covers the locking disc 4. To make the rotating rod 3 more stable, one end of the rotating rod 3 is connected to the protective cover 19 via a bearing. To allow an external system to know the number of rotations, the end of the rotating rod 3 is placed outside the protective cover 19 and is equipped with a trigger plate 20. A photoelectric switch 21 adapted to the trigger plate 20 is provided on the protective cover 19. Therefore, the number of rotations is fed back by triggering the photoelectric switch 21 once for each rotation.

[0026] 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.
