DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

The tops of the two support poles 1 are both equipped with identification devices 14. The identification devices 14 can select identification methods such as face recognition, fingerprint recognition, and card swiping recognition according to usage requirements, and can also integrate multiple identification methods. The bottom end of the support pole 1 is fixedly installed with a fixed base 3. One side of the two support poles 1 is movably connected with a door rod 2 through a connecting component. The two door rods 2 are movably opposed to each other, and a rubber pad is provided at the contact position to achieve a buffering effect. A telescopic drive tube 4 is connected between the door rod 2 and the support pole 1, and the telescopic drive tube 4 is a corrugated tube. A power cylinder 8 is installed on one side of the support pole 1, and a first oil delivery pipe 9 is connected to the end of the power cylinder 8, one end of the first oil delivery pipe 9 is connected to the telescopic drive pipe 4, and a power mechanism is arranged in the power cylinder 8; when in use, the two support poles 1 are first installed on both sides of the automatic door passage area through the fixed base 3, and the installation distance between the two support poles 1 can be adjusted according to needs. When in use, the power mechanism in the power cylinder 8 inputs the oil in the power cylinder 8 into the telescopic drive pipe 4 through the first oil delivery pipe 9, so that the telescopic drive pipe 4 is extended, thereby pushing the two door rods 2 to move in a direction close to each other, so that the two door rods 2 can be moved closer to each other. The two door rods 2 fit together, so that the pedestrian door is closed. When the identification device 14 identifies that a person is passing, the power mechanism inputs the oil in the telescopic drive tube 4 into the power cylinder 8 through the first oil delivery pipe 9, thereby driving the two door rods 2 to move, so that the two door rods 2 move away from each other, so that the pedestrian door is opened. This solution uses the power cylinder 8 to transport oil to make the telescopic drive tube 4 telescopic, so that the two door rods 2 move relative to each other, so that the pedestrian door is opened or closed. The telescopic length of the telescopic drive tube 4 can be adaptively adjusted according to the distance between the two supporting uprights 1, and the passage width of the pedestrian door can be adjusted according to the use requirements, which improves the installation and use. Convenience, and the movement of the door rod 2 is always in the vertical plane between the two supporting uprights 1.

Even if the distance between the passers-by and the pedestrian door is close, it will not affect the opening and closing of the pedestrian door. The movement of the two door rods 2 is independently controlled. When two-way passage is required, only the door rod 2 on one side can be driven to move, so that it can be used as a pedestrian door for two-way passage, which improves the scope of application and reduces the cost. The telescopic drive tube 4 is driven to retract and retract by the vertically arranged power cylinder 8 and the oil drive, so that the power structure occupies less space, the door rod 2 has a larger range of motion, and the occupied space is effectively reduced.

A transmission assembly for driving the slider 17 to rise and fall is provided below the mounting seat 15, and the slider 17 is elastically connected to the pedal 27 through the transmission assembly. When the pedal 27 is stepped on, the transmission assembly drives the slider 17 to move upward, so that the slider 17 extends out of the first groove; the transmission assembly includes a second oil pipeline 22, a first oil cylinder and a second oil cylinder, the telescopic end of the first oil cylinder is connected to the slider 17, and the telescopic end of the second oil cylinder is connected to the pressure sensor 26, and the second oil pipeline 22 The two ends are respectively connected with the first oil cylinder and the second oil cylinder; the first oil cylinder includes a first cylinder 19, a first plug rod 20 and a second piston 21, the first cylinder 19 is fixedly mounted on the bottom end of the mounting seat 15, the second piston 21 is slidably mounted in the first cylinder 19, the bottom end of the first plug rod 20 extends into the first cylinder 19 and is fixedly connected to the second piston 21, the top end of the first plug rod 20 extends into the first groove and is fixedly connected to the slider 17, and one end of the second oil delivery pipe 22 is connected with the first cylinder 19; The second oil cylinder includes a second cylinder barrel 23, a second plug rod 24 and a third piston 25. The second cylinder barrel 23 is fixedly installed on the ground. The third piston 25 is slidably installed in the second cylinder barrel 23.

The first cylinder barrel 19, the second cylinder barrel 23 and the second oil pipe 22 are all filled with oil.

[0038] When a pedestrian steps on the pedal 27, the pedal 27 is pressed and moves downward, so that the second plug rod 24 moves downward, so that the third piston 25 inputs the oil in the second cylinder 23 into the first cylinder 19 through the second oil delivery pipe 22, so that the second piston 21 drives the first plug rod 20 to move upward, so that the slider 17 moves upward, so that the slider 17 extends out of the first groove. As the pedestrian door is opened, the door rod 2 moves to the top of the mounting seat 15. At this time, the one-way block 16 enters the slot provided at the bottom end of the door rod 2, thereby locking the door rod 2, so that when the pedestrian does not leave the pedal 27, the door rod 2 is locked and will not move, thereby making the electromagnet 13 inoperative. It does not need to be opened for a long time. It only needs to turn on the electromagnet 13 for a period of time when the pedestrian steps on the pedal 27 to make the pedestrian door fully open, and then the electromagnet 13 can be turned off, thereby reducing energy consumption. When the pedestrian leaves the pedal 27, the pedal 27 moves upward and resets under the elastic action of the elastic support pad 28, so that the first cylinder and the second cylinder are reset, so that the slider 17 moves downward and resets, and then the one-way block 16 is moved out of the slot, thereby releasing the lock on the door rod 2, so that the door rod 2 moves to reset the pedestrian door, so that the pedestrian will not close when the pedestrian does not leave the pedal 27, thereby improving the safety of the use of the pedestrian door and preventing pedestrians from being accidentally injured when the pedestrian door is closed.

[0039] Working principle: When the pressure sensor 26 detects that a pedestrian steps on the pedal 27, the recognition device 14 turns on the camera for recognition. After successful recognition, the control electromagnet 13 is turned on. The electromagnet 13 attracts the two first pistons 10 to move toward the iron core through magnetic attraction, so that the oil in the telescopic drive tube 4 is input into the power cylinder 8 through the first oil delivery pipe 9, so that the telescopic drive tube 4 contracts, thereby driving the door rod 2 to move, so that the pedestrian door is opened for travel;

[0040] When the pedestrian steps on the pedal 27, the pedal 27 is pressed and moves downward, so that the second plug rod 24 moves downward, so that the third piston 25 inputs the oil in the second cylinder 23 into the first cylinder 19 through the second oil delivery pipe 22, so that the second piston 21 drives the first plug rod 20 to move upward, so that the slider 17 moves upward, so that the slider 17 extends out of the first groove. As the pedestrian door is opened, the door rod 2 moves to the top of the mounting seat 15. At this time, the one-way block 16 enters the slot opened at the bottom end of the door rod 2, thereby locking the door rod 2, so that the door rod 2 is locked and will not move when the pedestrian does not leave the pedal 27. When the pedestrian leaves the pedal 27, the pedal 27 moves upward and resets under the elastic action of the elastic support pad 28, so that the first oil cylinder and the second oil cylinder are reset, so that the slider 17 moves downward and resets, and then the one-way block 16 moves out of the slot, thereby releasing the lock on the door rod 2, so that the door rod 2 moves to reset the pedestrian door.

[0041] When in use, the advertising leaflet can be pasted on the advertising tape 30. When the pedestrian door is closed, the door rod 2 moves toward the direction close to the supporting pole 1. Under the action of the spring 33, the rotating cylinder 32 rotates, so that the advertising tape 30 is rolled up on the rotating cylinder 32, thereby storing the advertising tape 30. When the pedestrian door is opened, the door rod 2 moves toward the direction away from the supporting pole 1, thereby pulling the advertising tape 30 out of the storage box 29. The setting of the advertising tape 30 can close the gap between the supporting pole 1 and the door rod 2 to prevent pedestrians from reaching their hands between the supporting pole 1 and the door rod 2 to prevent their hands from being pinched.
