Description

Technical Field

[0001] The utility model relates to the field of anti-tailgating for subway gates, in particular to an anti-tailgating device for subway gates. Background Art

[0002] The turnstile is a channel blocking device (channel management equipment) used to manage pedestrian flow and regulate pedestrian entry and exit. It is mainly used in subway turnstile systems and toll ticket gate systems. The turnstile is used to identify the passage status of pedestrians, determine whether pedestrians are passing legally, and can determine whether pedestrians are within the movement range of the barrier to protect the personal safety of pedestrians. The most basic and core function of the turnstile is to allow only one person to pass at a time. It can be used at the entrance of various toll and access control occasions.

[0003] Traditional subway turnstiles are equipped with anti-tailgating devices, usually an AB door scheme, that is, when a passenger swipes his card, Gate A opens, and then closes immediately after the passenger enters. Only then will Gate B open. If there is another passenger following, he will be discovered by the infrared recognition or image recognition system. In this case, Gate A will not close and Gate B will not open. The trailing passenger can only exit the turnstile to resume normal operation.

[0004] However, this structure still has certain shortcomings in actual use: some passengers cannot communicate and are unwilling to exit Gates AB due to reasons such as fare evasion, unreasonableness, mental problems or lack of understanding of the working principle of the gate. Passengers who pass normally will be blocked, causing channel blockage. The current gate structure does not have a mandatory anti-tailgating function. Secondly, the shielding structure of a traditional gate is usually a baffle made of glass or plastic. Due to its large force-bearing area, it is easy to deform due to collision. Once the structure is damaged, it is not convenient to quickly replace it to clear the blockage.

[0005] Therefore, it is necessary to provide a new anti-tailgating device for subway gates to solve the above technical problems. Utility Model Content

[0006] The technical problem solved by the utility model is to provide an anti-tailgating device for subway gates which has a mandatory anti-tailgating function and a gate shielding structure which is not easily damaged and convenient for quick replacement of parts.

[0007] In order to solve the above technical problems, the utility model provides an anti-tailgating device for a subway gate, comprising: a body, a guide frame, an anti-tailgating assembly and a shielding assembly, wherein two guide frames are provided and are distributed on the left and right, a vertical groove is provided on the surface of the guide frame, and the anti-tailgating assembly comprises a baffle, two baffles are distributed longitudinally, one end of each of the two baffles is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the vertical groove on one side, a coil spring is installed on the surface of the rotating shaft located in the vertical groove, a convex block is fixedly connected to the inner wall of the vertical groove on one side of the rotating shaft, and a pressure sensor is installed on the surface of the convex block;

[0008] The main body is provided with two and is distributed on the left and right sides, and the side surfaces of the two bodies that are relatively close to each other are provided with mounting grooves, and the shielding assembly includes a first cylinder, the first cylinder is installed inside the mounting groove, the output end of the first cylinder is rotatably connected to the second connecting rod, the end of the second connecting rod is rotatably connected to the mounting piece, the mounting piece is rotatably connected to the surface of the main body, a limiting hole is vertically provided on the surface of the mounting piece, and a plurality of mounting holes arranged at equal intervals are longitudinally distributed on the surface of one side wall of the mounting piece, the mounting hole is connected to the limiting hole, a shielding rod is inserted into the inside of the mounting hole, and a plug hole is provided on the surface of the shielding rod, and the plug hole corresponds to the limiting hole, and an upper lock body and a lower lock body are respectively provided on the top and bottom of the mounting piece, and a fixing rod is fixedly connected to the bottom of the upper lock body, and one end of the fixing rod passes through the limiting hole and the plug hole and is connected to the lower lock body.

[0009] As a further solution of the utility model, a second cylinder is installed inside the guide frame located at one side of the pressure sensor, and a stopper is fixedly connected to the output end of the second cylinder, and the end of the stopper extends to the outside of the vertical slot.

[0010] Through the above technical solution, when the traditional AB door structure is in use, if the person behind follows the person in front who is passing normally to enter the gate, then the A door is in an open state. Unless the person behind takes the initiative to leave, the B door cannot be opened. In this case, if the person behind does not move due to the mentality of evading tickets, unreasonableness or misunderstanding, the person in front cannot pass smoothly. Therefore, the corresponding anti-tailgating component is added to the device. When a passenger enters the guide frame, if there is a person following behind, the infrared recognition system will sense it and issue an alarm to remind the person in front. At this time, the person can persuade the following person to go back through communication. When the communication is not smooth, the person in front can forcibly pull down the baffle to avoid wasting time. When the end of the baffle touches the pressure sensor, the second cylinder on one side pushes the block forward and jams the baffle, so that the following person is forced to be blocked outside the gate, and due to the design of the anti-support plates on both sides, the person can be prevented from jumping over. Only when the system recognizes that the person in front has passed smoothly, the block can be retreated, so that the baffle is reopened under the drive of the winding spring.

[0011] As a further solution of the utility model, a first connecting rod is rotatably connected between the two baffles, and a handle is fixedly connected to the surface of the baffle located on the upper side.

[0012] Through the above technical solution, the first connecting rod is designed to enable the two sets of baffles to move synchronously, and the handle makes it convenient for people who pass normally to pull down the baffles to forcibly isolate the people following behind.

[0013] As a further solution of the utility model, voice broadcast modules and signboards are longitudinally distributed on one side surface of the two guide frames relative to the main body, and an alarm light is connected to the surface of the guide frame on one side by bolts.

[0014] Through the above technical solution, setting up a voice broadcast module and a signboard can guide people to pass through here, and setting up an alarm light can remind normal passers-by that there are people following behind.

[0015] As a further solution of the utility model, anti-support plates are fixedly connected to the top surfaces of the two guide frames located on one side of the vertical slot.

[0016] Through the above technical solution, the anti-support plate can prevent ticket evaders from jumping over by supporting themselves with both hands on the guide frame, and the structural design is reasonable.

[0017] As a further solution of the utility model, a card reader and a facial recognition system are respectively installed on the top surface of the main body on one side, and an infrared recognition system is installed on the side wall surfaces of the two guide frames located on the lower side of the anti-support plate.

[0018] Through the above technical solution, setting up a card reader and a facial recognition system can facilitate the machine to identify the identity of fellow travelers and collect tolls.

[0019] As a further solution of the utility model, the surface of the pressure sensor abuts against the bottom of the baffle located on the upper side, and the baffle located on the upper side is between the pressure sensor and the stopper.

[0020] Through the above technical solution, the baffle can be restricted only when it is located between the pressure sensor and the stopper, thereby preventing the trailing personnel from pulling up the baffle at will.

[0021] Compared with the related art, the anti-tailgating device for subway gate provided by the utility model has the following beneficial effects:

[0022] 1. In the utility model, when the traditional AB door structure is in use, if the rear personnel follow the normal passing personnel in front to enter the gate, then the A door is in an open state. Unless the rear personnel take the initiative to leave, the B door cannot be opened. In this case, if the rear personnel do not move due to the reason of fare evasion, unreasonableness or misunderstanding, the front personnel cannot pass smoothly. Therefore, the corresponding anti-tailgating component is added to the device. When a passenger enters the guide frame, if there is a trailing person behind, the infrared recognition system will sense it and send out an alarm to remind the front personnel. At this time, the person can persuade the trailing person to go back through communication. When the communication is not smooth, the front personnel can forcibly pull down the baffle to avoid delaying time. When the end of the baffle touches the pressure sensor, the second cylinder on one side pushes the block forward and jams the baffle, so that the trailing person is forced to be blocked outside the gate. And due to the design of the anti-support plates on both sides, the person can be prevented from jumping over. Only when the system recognizes that the front personnel pass smoothly, the block can be retreated, so that the baffle is reopened under the drive of the coil spring;

[0023] 2. In the utility model, the baffle of the gate is replaced with a shielding rod in the structure. The force-bearing area of ​​a single rod is small and not easily damaged. At the same time, the second connecting rod is used as an oblique support, so that the strength of the structure is relatively high. When the structure has been used for a long time and the surface is damaged, the user can use the key to open the lower lock body so that the upper lock body and the fixed rod can be separated from the mounting parts. At this time, several shielding rods can be easily removed. This design is conducive to rapid maintenance and replacement by the staff to avoid affecting the passage of personnel.

Figure 1 ; Figure 4 This is a schematic diagram of the partial structure of an anti-tailgating device for a subway gate in the utility model. Figure 2 An anti-tailgating device for a subway gate includes:

[0032] A body 1, a guide frame 2, an anti-tailgating component 4 and a shielding component 5. Two guide frames 2 are provided and are distributed on the left and right. A vertical slot 3 is provided on the surface of the guide frame 2. The anti-tailgating component 4 includes a baffle 13. Two baffles 13 are distributed longitudinally. One end of each of the two baffles 13 is fixedly connected to a rotating shaft. The rotating shaft is rotatably connected to the inner wall of the vertical slot 3 on one side. A coil spring 26 is installed on the surface of the rotating shaft located in the vertical slot 3. A convex block is fixedly connected to the inner wall of the vertical slot 3 on the side opposite to the rotating shaft. A pressure sensor 25 is installed on the surface of the convex block.

[0033] The main body 1 is provided with two and is distributed on the left and right sides. The surfaces of the two relatively close sides of the two main bodies 1 are both provided with mounting grooves. The shielding component 5 includes a first cylinder 16, which is installed inside the mounting groove. The output end of the first cylinder 16 is rotatably connected to the second connecting rod 18, and the end of the second connecting rod 18 is rotatably connected to the mounting member 11. The mounting member 11 is rotatably connected to the surface of the main body 1. A limiting hole 21 is vertically provided on the surface of the mounting member 11. A plurality of mounting holes 22 arranged at equal intervals are longitudinally distributed on the surface of one side wall of the mounting member 11. The mounting hole 22 is connected to the limiting hole 21. A shielding rod 12 is inserted into the inside of the mounting hole 22. A plug hole 17 is provided on the surface of the shielding rod 12, and the plug hole 17 corresponds to the limiting hole 21. An upper lock body 20 and a lower lock body 19 are respectively provided on the top and bottom of the mounting member 11. A fixing rod is fixedly connected to the bottom of the upper lock body 20. One end of the fixing rod passes through the limiting hole 21 and the plug hole 17 and is connected to the lower lock body 19.

[0034] like Figure 1 As shown, a second cylinder 23 is installed inside the guide frame 2 located on one side of the pressure sensor 25 , and a stopper 24 is fixedly connected to the output end of the second cylinder 23 , and the end of the stopper 24 extends to the outside of the vertical slot 3 .

[0035] When the traditional AB door structure is in use, if the person behind follows the normal person in front to enter the gate, then the A door is in the open state, unless the person behind takes the initiative to leave, the B door cannot be opened. In this case, if the person behind does not move for reasons such as fare evasion, unreasonableness or misunderstanding, then the person in front cannot pass smoothly. Therefore, the device adds a corresponding anti-tailgating component 4. When a passenger enters the guide frame 2, if there is a person following behind, the infrared recognition system 7 will sense it and send an alarm to remind the person in front. When the communication is not smooth, the person in front can forcibly pull down the baffle 13 to avoid wasting time. When the end of the baffle 13 touches the pressure sensor 25, the second cylinder 23 on one side pushes the block 24 forward to jam the baffle 13, so that the following person is forced to be blocked outside the gate, and due to the design of the anti-support plates 6 on both sides, the person can be prevented from jumping over. Only when the system recognizes that the person in front has passed smoothly, the block 24 can be retracted, allowing the baffle 13 to be reopened under the drive of the coil spring 26.

[0036] like Figure 1 As shown, a first connecting rod 15 is rotatably connected between the two baffles 13, and a handle 27 is fixedly connected to the surface of the baffle 13 located on the upper side.

[0037] The first connecting rod 15 is designed to enable the two groups of baffles 13 to move synchronously, and the handle 27 makes it convenient for normal passers-by to pull down the baffles 13 to forcibly isolate the trailing persons.

[0038] like Figure 1 As shown, voice broadcast modules 14 and signboards 8 are longitudinally distributed on one side surface of the two guide frames 2 relative to the body 1, and an alarm light is connected to the surface of the guide frame 2 on one side by bolts.

[0039] The voice broadcast module 14 and the sign 8 are provided to guide people to pass through here, and the alarm light is provided to remind normal passers-by that there are people following behind.

[0040] like Figure 1 As shown, the top surfaces of the two guide frames 2 located on one side of the vertical slot 3 are both fixedly connected with anti-support plates 6.

[0041] The anti-support plate 6 can prevent ticket evaders from jumping over by supporting themselves with both hands on the guide frame 2 , and the structural design is reasonable.

[0042] like Figure 1 As shown, a card reader 9 and a facial recognition system are installed on the top surface of the main body 1 on one side, and an infrared recognition system 7 is installed on the side wall surfaces of the two guide frames 2 located under the anti-support plate 6.

[0043] The card reader 9 and the facial recognition system 10 are provided to facilitate the machine to identify the identity of the fellow passengers and collect tolls.

[0044] like Figure 1 As shown, the surface of the pressure sensor 25 abuts against the bottom of the baffle 13 located on the upper side, and the baffle 13 located on the upper side is between the pressure sensor 25 and the stopper 24.

[0045] The baffle 13 can be restricted only when it is located between the pressure sensor 25 and the stopper 24, thereby preventing the trailing person from pulling up the baffle 13 at will.

[0046] The working principle of the anti-tailgating device for subway gate provided by the utility model is as follows:

[0047] Step 1: When the traditional AB door structure is in use, if the person behind follows the normal person in front to enter the gate, then the A door is in the open state, unless the person behind takes the initiative to leave, otherwise the B door cannot be opened. In this case, if the person behind does not move for reasons such as fare evasion, unreasonableness or misunderstanding, then the person in front cannot pass smoothly. Therefore, the device adds a corresponding anti-tailgating component 4. When a passenger enters the guide frame 2, if there is a person following behind, the infrared recognition system 7 will sense it and issue an alarm to remind the person in front. The person on the other side can persuade the person behind to go back through communication. When the communication is not smooth, the person in front can forcibly pull down the baffle 13 to avoid delaying time. When the end of the baffle 13 touches the pressure sensor 25, the second cylinder 23 on one side pushes the block 24 forward to block the baffle 13, so that the person behind is forced to be blocked outside the gate. Due to the design of the anti-support plates 6 on both sides, the person can be prevented from jumping over. Only when the system recognizes that the person in front has passed smoothly, the block 24 can retreat, so that the baffle 13 is reopened under the drive of the coil spring 26.

[0048] The second step: In this structure, the baffle of the gate is replaced with a shielding rod 12. The force-bearing area of ​​a single rod is small and not easily damaged. At the same time, the second connecting rod 18 serves as an oblique support, which makes the strength of the structure higher. When the structure has been used for a long time and the surface is damaged, the user can use the key to open the lower lock body 19, so that the upper lock body 20 and the fixed rod can be separated from the mounting part 11. At this time, several shielding rods 12 can be easily removed. This design is conducive to rapid maintenance and replacement by the staff to avoid affecting the passage of people.
