Description

Technical Field

[0001] The present invention relates to the technical field of wing gate equipment, and more specifically to a novel physical anti-pinch pedestrian wing gate. Background Art

[0002] The wing gate is mainly used for pedestrian passage management. It has the characteristics of fast opening, safety, and convenience. It is an ideal management and guidance equipment for pedestrians with high frequency of access. It is now widely used in airports, subway stations, stations, docks, scenic spots, parks, unit pedestrian passages, etc. It can be used with smart cards to realize the function of offline ticket management system and form unattended management of personnel entry and exit. The wing gate is generally equipped with an anti-pinch device to prevent people from being pinched by the wing gate when passing through and getting injured. The traditional wing gate anti-pinch needs to be achieved through the mainboard algorithm and the motor drive. It is costly and can only take effect under a certain amount of force. It cannot guarantee 100% anti-pinch effect. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a new type of physical anti-pinch pedestrian wing gate, which can ensure the anti-pinch function by adopting a physical buffer structure, does not require a main board and a specific motor drive to execute, and has good reliability and practicality.

[0004] The technical solution of the present invention is to provide a new type of physical anti-pinch pedestrian wing gate, including a small wing panel, a large wing panel and a wing panel driving device. The wing panel driving device is used to drive the small wing panel and the large wing panel to swing left or right. The small wing panel is hinged on the large wing panel. The wing panel driving device includes a synchronous transmission assembly, a first connecting rod, a rotating arm, a third connecting rod, a second connecting rod, and a fourth connecting rod. The first connecting rod and the rotating arm are both driven by the synchronous transmission assembly to rotate. The rotating arm and the third connecting rod are both hinged on the large wing panel. The rotating arm can push the large wing panel to swing left and right. The first connecting rod is hinged on the second connecting rod and can drive the second connecting rod to move up and down. The other end of the second connecting rod is hinged to the third connecting rod and the fourth connecting rod. The second connecting rod can drive the third connecting rod and the fourth connecting rod to rotate. The fourth connecting rod is hinged on the small wing panel and can push the small wing panel to swing left and right. The second connecting rod is retractable.

[0005] Compared with the prior art, the novel physical anti-pinch pedestrian wing gate of the present invention has the following advantages: during the closing process of the wing gate, the synchronous transmission assembly drives the rotating arm to rotate, so that the rotating arm pushes the large wing plate to swing outward; the synchronous transmission assembly drives the first connecting rod to rotate, the first connecting rod pulls the second connecting rod, the second connecting rod drives the third connecting rod and the fourth connecting rod to rotate in opposite directions, and the fourth connecting rod pushes the small wing plate to swing outward until the third connecting rod and the fourth connecting rod are in the same horizontal straight line, the large and small wing plates are swung outward into place, and the wing gate is closed; when the wing gate is not completely closed, if someone is clamped in the wing gate, the small wing plate is subjected to a force to swing inward, The fourth link is pushed to rotate and the second link is driven to extend and retract, so as to avoid the third link and the fourth link being in the same horizontal straight line, so that the fourth link cannot push the small wing plate to swing outward into place, and the force applied by the wing gate to the clamped person is very small, which can play a certain anti-pinch effect; after the wing gate is fully closed, the third link and the fourth link are in the same horizontal straight line. If a force is applied to the small wing plate to swing inward manually, the force is also transmitted to the fourth link in the horizontal direction, and the second link cannot be driven to extend and retract, and the fourth link cannot pull the small wing plate to swing inward, so that the situation of forcibly opening the wing gate by humans can be avoided.

[0006] Preferably, the second connecting rod comprises an upper connecting block, a lower connecting block and a telescopic rod connecting the upper connecting block and the lower connecting block, the upper connecting block is hinged to the ends of the third connecting rod and the fourth connecting rod, the lower connecting block is hinged to the end of the first connecting rod, a slide is arranged in the upper connecting block and / or the lower connecting block, the telescopic rod can slide in the slide, a spring is arranged on the telescopic rod, and the two ends of the spring are respectively connected to the two opposite ends of the upper connecting block and the lower connecting block. With this structure, when the second connecting rod is driven to extend and retract, the spring can play a buffering role. If someone is caught in the wing gate, the second connecting rod can slowly move upward or downward under the action of the spring, so that the force acting on the wing gate on the person caught is very small, thereby preventing the third connecting rod and the fourth connecting rod from being in the same horizontal straight line, so that the fourth connecting rod cannot push the small wing plate to swing outward to a certain position, and plays an anti-clip role.

[0007] Preferably, a rotating arm pin is fixedly arranged on the large wing plate, and the rotating arm and the third connecting rod are both hinged on the large wing plate by being rotatably connected to the rotating arm pin. With this structure, it is convenient to connect and assemble the rotating arm and the third connecting rod, and it is also convenient for the rotating arm to push the large wing plate to swing.

[0008] Preferably, the second connecting rod pin is further included, and the ends of the second connecting rod, the third connecting rod and the fourth connecting rod are hinged together by being rotatably connected to the second connecting rod pin. This structure is convenient for connecting and assembling the second connecting rod, the third connecting rod and the fourth connecting rod.

[0009] Preferably, the first connecting rod pin is further included, and the ends of the first connecting rod and the second connecting rod are hinged together by being rotatably connected to the first connecting rod pin. This structure is convenient for connecting and assembling the first connecting rod and the second connecting rod.

[0010] Preferably, a receiving cavity and an entrance and exit are provided in the large wing plate, a small wing plate pin is fixedly provided in the receiving cavity, the small wing plate is provided in the receiving cavity of the large wing plate and is rotatably connected to the small wing plate pin, and the small wing plate can extend out of the receiving cavity or retract into the receiving cavity through the entrance and exit. With this structure, space is fully utilized, the structure is reasonable and beautiful, and the situation that the small wing plate is forcibly pulled to open the wing gate can be avoided.

[0011] Preferably, the synchronous transmission assembly is a synchronous belt transmission assembly composed of a driving wheel, a driven wheel, and a belt. This structure is simple and easy to implement, and the transmission capacity of the synchronous belt transmission assembly is affected by the belt tension, which can prevent the wing gate from closing too quickly and injuring people.

[0012] Preferably, the synchronous transmission assembly is composed of mutually meshing gear sets. With this structure, it is simple and easy to implement, and the torque of the gear transmission is large, which can ensure that the opening or closing of the wing gate is accurately controlled.

[0013] Preferably, the synchronous transmission assembly is driven by a motor. This structure is simple and easy to implement. When the motor is out of control or cannot output torque normally, the synchronous transmission assembly can also be driven manually to avoid pedestrians being stranded.

[0020] Embodiment 1:

[0021] like Figure 1 and Figure 2 As shown in the figure, the new physical anti-pinch pedestrian wing gate of the present invention includes a small wing plate 15, a large wing plate 16 and a wing plate driving device, and the wing plate driving device is used to drive the small wing plate 15 and the large wing plate 16 to swing left or right; the large wing plate 16 is provided with a accommodating cavity and an external entrance and exit 16-1, and a small wing plate pin shaft 14 is fixedly provided in the accommodating cavity. The small wing plate 15 is arranged in the accommodating cavity of the large wing plate 16 and is connected to the small wing plate pin shaft 14. The small wing plate 15 can rotate left and right around the small wing plate pin shaft 14, so that it can enter and exit the accommodating cavity through the entrance and exit 16-1.

[0022] The wing plate driving device includes a driving wheel 1, a driven wheel 2, a belt 3, a first connecting rod 4, a rotating arm 5, a third connecting rod 6, a second connecting rod 7, a fourth connecting rod 8, a rotating arm pin 11, a second connecting rod pin 12, and a first connecting rod pin 13. The driving wheel 1 and the driven wheel 2 are connected and driven by the belt 3; a rotating arm pin 11 is fixedly arranged in the accommodating cavity of the large wing plate 16, one end of the rotating arm 5 is rotatably connected to the rotating arm pin 11, and the other end is connected to the driving wheel 1 and driven by the driving wheel 1 and rotates; one end of the first connecting rod 4 is connected to the driven wheel 2 and is driven to rotate by the driven wheel 2, and the other end is rotatably connected to the first connecting rod pin 13; the two ends of the second connecting rod 7 are rotatably connected to the first connecting rod pin 13 and the second connecting rod pin 12 respectively; the two ends of the third connecting rod 6 are rotatably connected to the rotating arm pin 11 and the second connecting rod pin 12 respectively; one end of the fourth connecting rod 8 is hinged on the small wing plate 15, and the other end is rotatably connected to the second connecting rod pin 12.

[0023] The second connecting rod 7 is retractable, and includes an upper connecting block 7-3, a lower connecting block 7-2, and two telescopic rods 7-1 connecting the upper connecting block 7-3 and the lower connecting block 7-2. The upper connecting block 7-3 is connected to the second connecting rod pin 12, and the lower connecting block 7-2 is connected to the first connecting rod pin 13. A slideway is provided in the upper connecting block 7-3 and / or the lower connecting block 7-2, and the two telescopic rods 7-1 can slide in the slideway at the same time, so that the telescopic rod 7-1 can extend or retract into the upper connecting block 7-3 and / or the lower connecting block 7-2. A spring is provided on the telescopic rod 7-1, and the two ends of the spring are respectively connected to the opposite ends of the upper connecting block 7-3 and the lower connecting block 7-2; when the telescopic rod 7-1 retracts into the upper connecting block 7-3 and / or the lower connecting block 7-2, the spring is compressed; when the telescopic rod 7-1 extends out of the upper connecting block 7-3 and / or the lower connecting block 7-2, the spring rebounds to restore the original length or is stretched.

[0024] When the new physical anti-pinch pedestrian wing gate of the present invention switches from an open state to a closed state, the driving wheel 1 is driven to output torque, and the driven wheel 2 rotates synchronously. The driving wheel 1 drives the rotating arm 5 to rotate right, and the rotating arm 5 pushes the rotating arm pin 11 to make the large wing plate 16 swing to the right. At the same time, the driven wheel 2 drives the first connecting rod 4 to rotate right, and the first connecting rod 4 pulls the second connecting rod 7 downward, and the second connecting rod 7 simultaneously pulls the third connecting rod 6 and the fourth connecting rod 8, so that the third connecting rod 6 rotates clockwise around the rotating arm pin 11, and the fourth connecting rod 8 rotates counterclockwise around the second connecting rod pin 12 while pushing the small wing plate 15 to the right, so that the small wing plate 15 swings to the right around the small wing plate pin 14 and extends out of the large wing plate 16 from the entrance and exit 16-1 until the third connecting rod 6 and the fourth connecting rod 8 rotate to the same horizontal straight line, and the second connecting rod 7 is pulled down to the lowest position by the first connecting rod 4, and the new physical anti-pinch pedestrian wing gate of the present invention is in a closed state. The driving wheel 1 can be driven by a motor or manually.

[0025] During the above process, the upper connecting block 7-3 is pressed downward by the third connecting rod 6 and the fourth connecting rod 8, the second connecting rod 7 is always compressed, the telescopic rod 7-1 is retracted into the upper connecting block 7-3 and / or the lower connecting block 7-2, and the spring on the telescopic rod 7-1 is compressed. If someone is trapped in the wing gate, the small wing plate 15 is subjected to a force to the left. At this time, the spring can play a buffering role, so that the upper connecting block 7-3 drives the second connecting rod pin 12 to move up and down, avoiding the third connecting rod 6 and the fourth connecting rod 8 from being in the same horizontal straight line, so that the fourth connecting rod 8 cannot push the small wing plate 15 to swing to the right to a fully closed state or pull the small wing plate 15 to swing to the left. In this case, the person trapped is subjected to very little force from the wing gate, which plays an anti-pinch role.

[0026] When the new physical anti-pinch pedestrian wing gate of the present invention is in a normal closed state, the third link 6 and the fourth link 8 are in the same horizontal straight line, exerting a force to push the small wing plate 15 to the left, and the force is transmitted to the second link pin 12 in a horizontal direction, making it impossible for the second link pin 12 to move up and down, and also impossible for the fourth link 8 to pull the small wing plate 15 to swing to the left, thereby avoiding the situation where the small wing plate 15 is forcibly retracted into the large wing plate 16 to open the wing gate.

[0027] When the new physical anti-pinch pedestrian wing gate of the present invention switches from a closed state to an open state, it only needs to reversely drive the active wheel 1, so that the rotating arm 5 pulls the rotating arm pin 11 to the left to make the large wing plate 16 swing to the left, and at the same time, the first connecting rod 4 rotates to the left and pushes the second connecting rod 7 upward, and the second connecting rod 7 pushes the third connecting rod 6 and the fourth connecting rod 8 at the same time, so that the third connecting rod 6 rotates counterclockwise around the rotating arm pin 11, and the fourth connecting rod 8 rotates clockwise around the second connecting rod pin 12 while pulling the small wing plate 15 to the left, so that the small wing plate 15 swings to the left around the small wing plate pin 14 until it is retracted from the entrance and exit 16-1 into the large wing plate 16. At this time, the new physical anti-pinch pedestrian wing gate of the present invention is in an open state.

[0028] Embodiment 2:

[0029] The difference between the new physical anti-pinch pedestrian wing gate in this embodiment and embodiment 1 is that the wing plate driving device adopts a transmission gear set to replace the synchronous belt transmission assembly composed of the driving wheel 1, the driven wheel 2, and the belt 3.

[0030] The above are only specific embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should all be included in the protection scope of the claims of the present invention.
