Description

Technical Field

[0001] This utility model relates to the field of full-height turnstiles, and in particular to the mechanism of full-height turnstiles. Background Technology

[0002] Full-height turnstiles, as high-security access control equipment, are widely used in subways, airports, and other locations requiring strict control. Their core function is to achieve one-way passage for personnel through a combination of mechanical blocking and electronic control. The traditional structure consists of a gate arm, a mechanism, sensors, and a control system. The locking reliability of the mechanism directly determines the equipment's anti-tailgating and anti-collision performance.

[0003] Current mainstream mechanisms use a solenoid valve to drive the locking tongue to radially lock the drive shaft, relying on continuous power to maintain the locked state. When the drive shaft rotates, the solenoid valve is energized to retract the locking tongue and release the limit; during reset, the solenoid valve is de-energized and the locking tongue is ejected to complete axial fixation. Although this structure meets basic requirements, it has a fatal flaw: in the event of a sudden power failure, the solenoid valve immediately loses its magnetism and releases the locking tongue, causing the drive shaft to be in a free state, and the gate lever can be pushed at will, losing its safety barrier function. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a mechanism for a full-height turnstile, which can effectively solve the technical problem that the mechanism fails after a power outage and cannot lock.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The mechanism of the full-height turnstile includes a support platform. The support platform houses a power shaft that drives the turnstile lever, an automatic reset component that resets the power shaft after rotation, and a positioning component that locks the power shaft. The surface of the power shaft is equipped with a reset plate for the paired automatic reset component and a positioning plate for the paired positioning component. The positioning component includes two symmetrical positioning locking rods and two geared motors. Each positioning locking rod has a long rod section and a short rod section, with a corner section between them. The positioning locking rods are "7"-shaped. The corner section of the positioning locking rod is rotatably connected to the support platform via a rotating shaft. The long rod section of the positioning locking rod is drive-connected to the geared motor. The short rod section of the positioning locking rod can restrict the rotation of the positioning plate. A manual gate-opening lock head is located on one side opposite the two positioning locking rods. The lock hole of the manual gate-opening lock head extends to the lower surface of the support platform. An eccentric wheel is located at the end of the manual gate-opening lock head away from the lock hole. The manual gate-opening lock head can drive the eccentric wheel to rotate, and the rotation of the two eccentric wheels can respectively push the long rod sections of the two positioning locking rods.

[0007] Furthermore, the edge of the positioning disk is provided with three or more protruding teeth at equal intervals, and the two positioning locking rods can respectively abut against the two sides of the protruding teeth.

[0008] Furthermore, one end of the power shaft extends to the surface of the support platform and is provided with a pin hole for connection with the rotating rod.

[0009] Furthermore, the automatic reset assembly includes a reset rod and a tension spring. The reset rod is "gate" shaped and is connected to the support platform via the tension spring. A push bearing is provided on the surface of the reset rod. The edge of the reset plate is provided with three or more convex lobes at equal intervals, forming a valley between the convex lobes. The push bearing can slide on the edge of the push bearing.

[0010] Furthermore, the reset lever is composed of a crossbeam and a linear guide rail. The linear guide rail is arranged parallel to both ends of the crossbeam. The tension spring is connected to the linear guide rail. The push bearing is located in the middle section of the crossbeam. A linear bearing is fixedly installed in the bearing platform. The linear guide rail is slidably connected to the linear bearing.

[0011] Furthermore, the reset assembly is located on the surface of the support platform, and the reset disk extends to the outside of the support platform.

[0012] Furthermore, the output shafts of the two geared motors are connected to gears, and the long rod of the positioning locking rod is provided with a rack that meshes with the gears.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The geared motor drives the positioning locking rod to press against the positioning disk. When the positioning disk rotates on one side, it pushes the short rod of the corresponding locking rod, forcing the long rod to deflect towards the manual unlocking lock head. At this time, the eccentric wheel presses against the long rod to form a self-lock, realizing the unidirectional irreversible movement of the power shaft. When the two positioning locking rods press against the positioning disk at the same time, the power shaft is completely locked, resisting the impact of positive and negative external forces. The pure mechanical locking structure does not rely on electricity to maintain, and it still maintains the locked state after power failure. The manual unlocking lock head is opened by rotating the key. The eccentric wheel pushes the long rod of the positioning locking rod, and the short rod of the positioning locking rod disengages from the positioning disk. In addition to the mechanical locking state, it supports a dual redundant design of motor-driven unlocking and manual mechanical unlocking. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is combined Figures 1-9 The mechanism of the full-height turnstile of this utility model is described in detail below:

[0026] The mechanism of the full-height turnstile includes a support platform 1. The support platform 1 houses a power shaft 2 that drives the turnstile arm, an automatic reset assembly 3 that resets the power shaft 2 after rotation, and a positioning assembly 4 that locks the power shaft 2. The surface of the power shaft 2 is provided with a reset disc 11 paired with the automatic reset assembly 3 and a positioning disc 10 paired with the positioning assembly 4. One end of the power shaft 2 extends to the surface of the support platform 1 and is provided with a pin hole for connection to the turnstile arm. The exposed shaft end design accommodates standardized pin holes, supporting quick assembly and disassembly of the turnstile arm module. The positioning assembly 4 includes two symmetrical positioning locking rods 5 and two geared motors 6. The positioning locking rods 5 are provided with a long rod portion 501 and a short rod portion 502. The section between 2 is a corner section. The positioning locking rod 5 is in the shape of a "7". The corner section of the positioning locking rod 5 is rotatably connected to the bearing platform 1 through the rotating shaft 7. The output shafts of the two reduction motors 6 are connected to gears 601. The long rod section 501 of the positioning locking rod 5 is provided with a rack 503 that meshes with the gear 601. The short rod section 502 of the positioning locking rod 5 can restrict the rotation of the positioning disk 10. A manual unlocking lock head 8 is provided on the opposite side of the two positioning locking rods 5. The lock hole of the manual unlocking lock head 8 extends to the lower surface of the bearing platform 1. An eccentric wheel 9 is provided at the end of the manual unlocking lock head 8 away from the lock hole. The manual unlocking lock head 8 can drive the eccentric wheel 9 to rotate. The rotation of the two eccentric wheels 9 can push the long rod section 501 of the two positioning locking rods 5 respectively.

[0027] The geared motor 6 drives the positioning locking rod 5 to press against the positioning disk 10. When the positioning disk 10 rotates on one side, it pushes the corresponding short rod part 502 of the locking rod, forcing the long rod part 501 to deflect towards the manual unlocking lock head 8. At this time, the eccentric wheel 9 presses against the long rod part 501 to form a self-lock, realizing the unidirectional irreversible movement of the power shaft 2. When both positioning locking rods 5 press against the positioning disk 10 at the same time, the power shaft 2 is completely locked, resisting the impact of positive and negative external forces. The purely mechanical locking structure does not rely on electricity for maintenance and remains locked after power failure. The manual unlocking lock head 8 is opened by rotating the key, and the eccentric wheel 9 pushes the long rod part 501 of the positioning locking rod 5, causing the short rod part 502 of the positioning locking rod 5 to disengage from the positioning disk 10. In addition to the mechanical locking state, it supports a dual redundant design of motor-driven unlocking and manual mechanical unlocking. The geared motor 6 only needs to be energized when driving the positioning locking rod 5 to rotate. After the positioning locking rod 5 presses against the positioning disk 10, it is locked through a mechanical structure, reducing power consumption. In traditional structures, the solenoid valve needs to be continuously energized to achieve locking.

[0028] The positioning disk 10 has three protruding teeth 1001 evenly spaced on its edge. Two positioning locking rods 5 can be placed on both sides of the protruding teeth 1001 respectively, thereby locking the power shaft 2 in both forward and reverse directions. The number of protruding teeth 1001 is consistent with the number of zones of the turnstile.

[0029] The automatic reset assembly 3 includes a reset lever 12 and a tension spring 13. The reset lever 12 is "gate" shaped and is connected to the support platform 1 via the tension spring 13. A push bearing 14 is provided on the surface of the reset lever 12. Three convex lobes 1101 are equidistantly arranged on the edge of the reset disk 11. The number of convex lobes 1101 is the same as the number of protruding teeth 1001. A trough 1102 is formed between the convex lobes 1101. After the push bearing 14 slides along its edge, the power shaft 2 stops rotating at the trough 1102. The structure of the convex lobes 1101 and the trough 1102, together with the push bearing 14, forms a three-stage braking system: sliding buffer, trough 1102 positioning, and tension spring 13 locking. The center line of the protruding teeth 1001 of the positioning disk 10 is aligned with the center of the cam trough of the reset disk 11, so that after successful reset, the positioning locking rod 5 can abut against the protruding teeth 1001 of the positioning disk 10, thereby achieving locking.

[0030] The reset lever 12 consists of a crossbeam 1201 and a linear guide rail 1202. The linear guide rail 1202 is arranged parallel to both ends of the crossbeam 1201. A tension spring 13 is connected to the linear guide rail 1202. A push bearing 14 is located in the middle section of the crossbeam 1201. A linear bearing 15 is fixedly installed in the bearing platform 1. The linear guide rail 1202 is slidably connected to the linear bearing 15. The linear guide rail 1202 and the bearing platform 1 are slidably connected to the linear bearing 15, which significantly improves the guiding accuracy and stability of the reset process. Linear motion reduces frictional resistance, avoids jamming, and ensures fast and consistent reset action, making it suitable for high-frequency opening and closing scenarios while reducing mechanical wear. The reset assembly is located on the surface of the bearing platform 1, and the reset disk 11 extends to the outside of the bearing platform 1. Setting the reset assembly and reset disk 11 on the outside of the bearing platform 1 facilitates on-site debugging, cleaning, and troubleshooting.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
