Description

Technical Field

[0001] The present invention relates to the technical field of anti-tailgating doors, and in particular to an anti-tailgating corner door control device and a use method. Background Art

[0002] With the development of society, some emerging industries and new scenarios have emerged, which require small footprint and short entry and exit time for anti-tailgating entrances and exits. Traditional cross-shaped anti-tailgating rolling gates and front and rear door anti-tailgating door systems can no longer meet the needs of some scenarios. For example: smart food pickup and express delivery warehouses, the floor space of the community is limited, generally controlled within 25 square meters. If a cross-shaped anti-tailgating rolling gate is used, the floor space of the two rolling gates will be more than 7 square meters, which is not only costly but also large in floor space. In addition, during the peak period of residents picking up items at night, if a traditional front and rear door anti-tailgating access control system is used, when a person walks into the front door, the system confirms that there is only one person in the detection area after the front door is closed, and then opens the back door. After the person enters the warehouse and the back door is closed, the next person is allowed to open the front door. Each time a person enters, The front door and the rear door need to be opened and closed once each, plus the anti-tailgating door for leaving the warehouse requires a total of 8 door openings and closings. This type of door is electric and has an anti-pinch function, and the closing time cannot be too fast. If calculated at 2 seconds per door opening and closing, plus the time to pick up the express in the warehouse, each person needs about 30 seconds to pick up the express, and 30 minutes can only meet the needs of about 60 people to pick up the express. If it is the peak time for picking up express at night, especially for picking up vegetables and cooking, the anti-tailgating door in the form of the front and rear doors is not only extremely costly but also cannot meet the requirements of users buying vegetables online and picking up vegetables in the warehouse offline.

[0019] A method for using an anti-tailgating corner door device includes the following steps:

[0020] (1) When used as an entrance door:

[0021] 1) Prevent people outside the door from following others into the door when entering. When a person enters the door, open the mobile APP and pass through the main control machine for identification and verification by methods such as scanning the code or face recognition. If the main control machine does not receive the human body induction signal or humanoid image induction signal from the sensor (C), the main control machine issues an opening command, the electric lock device (3) is opened, the lock head (3-1) disengages from the lock hole (3-2), and the corner door (1) is opened. When the person pulls open the swing door (1-1) of the corner door (1) to enter, the sensor (C) senses the human body induction signal or humanoid image induction signal. The main control machine receives the signal and issues an instruction, and the electric lock tooth device (2-1) on the lock tooth assembly (2) operates. The lock tooth bolt (2-1-1) on the electric lock tooth device (2-1) changes from the retracted state to the extended state, locking the opening rotation direction of the gear (2-2) and the shaft rod (2-3). Since the connection head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connection port 1-1-2 on the connecting part (1-1-1), the rotation of the corner door (1) in the opening direction is synchronously locked, and the corner door (1) can only rotate in the closing direction under the action of the built-in or external door closer device (4) and cannot be pulled open. This prevents someone from pulling the door outside to follow others into the door when the swing door (1-1) of the corner door (1) is not closed to the initial closed position and the main control machine does not issue an opening command again. Since the connection head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the upper interface 4-3-1 of the connecting part 4-3, and the rotating shaft (4-2) of the external door closer device (4) is inserted into the lower interface 4-3-2 of the connecting part 4-3, locking the opening rotation direction of the rotating shaft (4-2), the external door closer device (4) and the corner door (1) are synchronously locked in the opening rotation direction. The corner door (1) can only rotate in the closing direction under the action of the external door closer device (4) and cannot be pulled open. This prevents someone from pulling the door outside to follow others into the door when the swing door (1-1) of the corner door (1) is not closed to the initial closed position and the main control machine does not issue an opening command again.

[0022] (2) Prevent people inside the door from following when entering the door. When people enter the door, they open the mobile APP and pass through the main control unit for identification and verification through methods such as scanning the code or face recognition. If there is someone inside the door, when the main control unit receives the human body induction signal or humanoid image induction signal from the sensor (C), the main control unit does not issue an opening instruction, the electric door locking device (3) does not act, and the corner door (1) cannot be opened; when the sensor (C) does not sense the human body induction signal or humanoid image induction signal inside the door, the main control unit issues an opening instruction, the electric door locking device (3) is opened, the lock head (3-1) disengages from the lock hole (3-2), and just after the corner door (1) is opened, if someone comes inside the door, the sensor (C) senses the human body induction signal or humanoid image induction signal, the main control unit receives the signal and issues an instruction, and the electric lock tooth device (2-1) on the lock tooth assembly (2) acts, and the lock tooth bolt (2-1-1) changes from the retracted state to the extended state, locking the opening rotation direction of the gear (2-2) and the shaft rod (2-3); since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connecting port 1-1-2 on the connecting piece (1-1-1), the rotation of the corner door (1) in the opening direction is synchronously locked, and the corner door (1) can only rotate in the closing direction under the action of the built-in or external door closer device (4) and cannot be pulled open, preventing someone from pushing the door out from the inside when the swing door (1-1) of the corner door (1) is just opened or not closed to the initial closed position; since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the upper interface 4-3-1 of the connecting piece 4-3, and the rotating shaft (4-2) of the external door closer device (4) is inserted into the lower interface 4-3-2 of the connecting piece 4-3, the opening rotation direction of the rotating shaft (4-2) is locked, resulting in the synchronous locking of the rotation of the external door closer device (4) and the corner door (1) in the opening direction, and the corner door (1) can only rotate in the closing direction under the action of the external door closer device (4) and cannot be pulled open, preventing someone from pushing the door out from the inside when the swing door (1-1) of the corner door (1) is just opened or not closed to the initial closed position; when the corner door (1) is closed to the initial closed position under the action of the built-in or external door closer device (4), the electric door locking device (3) is closed (the lock head 3-1 is inserted into the lock hole 3-2), and the corner door (1) is closed; the main control unit issues an instruction, and the electric lock tooth device (2-1) acts, and the lock tooth bolt (2-1-1) on the electric lock tooth device (2-1) returns from the extended state to the retracted state;

[0023] (2) When used for going out:

[0024] 1) Prevent people inside the door from following out when going out. When a person goes out, they open the mobile APP and submit a door opening application to the main control unit through methods such as scanning a code or face recognition. When the main control unit receives the application and also receives the human body induction signal or humanoid image induction signal from the sensor (C), the main control unit issues a door opening command, and the electric door locking device (3) is activated. The lock head (3-1) disengages from the lock hole (3-2), and the corner door (1) opens. After the person pushes open the swing door (1-1) of the corner door (1) and goes out, when the corner door (1) rotates 30-45° in the closing direction under the action of the built-in or external door closer device (4), there is no one in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4, that is, at this time the sensor (C) cannot sense the human body induction signal or the humanoid image induction signal. The main control unit issues an instruction, and the electric lock tooth device (2-1) on the lock tooth assembly (2) acts, and the lock tooth bolt (2-1-1) changes from the retracted state to the extended state, locking the opening rotation direction of the gear (2-2) and the shaft rod (2-3); since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connecting port 1-1-2 on the connecting member (1-1-1), the rotation of the corner door (1) in the opening direction is locked synchronously, and the corner door (1) can only rotate in the closing direction under the action of the built-in or external door closer device (4) and cannot be pushed open, preventing someone from pushing out from the inside of the door when the swing door (1-1) of the corner door (1) is not closed to the initial closed position or the main control unit does not issue a door opening instruction again; since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the upper interface 4-3-1 of the connecting member 4-3, and the rotating shaft (4-2) of the external door closer device (4) is inserted into the lower interface 4-3-2 of the connecting member 4-3, the opening rotation direction of the rotating shaft (4-2) is locked, resulting in the synchronous locking of the opening rotation direction of the external door closer device (4) and the corner door (1), and the corner door (1) can only rotate in the closing direction under the action of the external door closer device (4) and cannot be pushed open, preventing someone from pushing out from the inside of the door when the swing door (1-1) of the corner door (1) is not closed to the initial closed position or the main control unit does not issue a door opening instruction again; when the corner door (1) closes to the initial position under the action of the built-in or external door closer device (4), the electric door locking device (3) acts, and the lock head 3-1 is inserted into the lock hole 3-2, and the corner door (1) closes; the main control unit issues an instruction, and the electric lock tooth device (2-1) acts, and the lock tooth bolt (2-1-1) on the electric lock tooth device (2-1) returns from the extended state to the retracted state;

[0025] 2) Prevent people outside from following in after someone goes out. When a person goes out, they open the mobile APP and submit a door opening application to the main control unit through methods such as barcode scanning or face recognition. When the main control unit receives the application and also receives the human body induction signal or humanoid image induction signal from sensor (C), the main control unit issues a door opening command. The electric door locking device (3) is activated, the lock head (3-1) disengages from the lock hole (3-2), and the corner door (1) opens. After the person pushes open the swing door (1-1) of the corner door (1) and goes out, when the corner door (1) rotates 30-45° in the closing direction under the action of the built-in or external door closer device (4), if there is someone (someone following in) in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4, that is, when the sensor (C) senses the human body induction signal or the humanoid image induction signal at this time, the main control unit issues an instruction, and the electric anti-tooth device (2-4) on the door frame operates. The anti-tooth bolt (2-4-1) on the electric anti-tooth device (2-4) changes from the retracted state to the extended state, locking the closing rotation direction of the gear (2-2) and the shaft rod (2-3); since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connection port 1-1-2 on the connecting member (1-1-1), the rotation of the corner door (1) in the closing direction is synchronously locked. The person (the person following in) in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4 can only push the swing door (1-1) of the corner door (1) in the opening direction to leave. After the person who wants to follow in leaves, the sensor (C) in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4 does not sense the human body induction signal or the humanoid image induction signal. The main control unit issues an instruction, and the electric anti-tooth device (2-4) on the door frame operates. After the anti-tooth bolt (2-4-1) on the electric anti-tooth device (2-4) changes from the extended state to the retracted state, the system continues to execute the program action of "preventing people inside from following out after someone goes out".

[0026] Usage method of the anti-tailgating angular door device: When the courier pulls the cart into the warehouse to deliver goods or large express items, when the swing door (1-1) and the shielding door (1-2) of the angular door (1) need to be opened from 90° to 180°, insert the key into the button lock (7) and rotate it. The pulling rope (5-3) connected to it drives the pulling handle (5-2) on the impact latch (5) at the other end to move, so that the locking tongue (5-1) on the impact latch (5) is opened, and the locking hook (6-1) on the fixing angle piece (6) is disengaged from the locking tongue (5-1). The swing door (1-1) and the shielding door (1-2) are opened from 90° to 180° through a set of hinges (8); after the courier pulls the cart into the warehouse to deliver goods, when the swing door (1-1) and the shielding door (1-2) are closed from 180° to 90°, the locking hook (6-1) impacts the locking tongue (5-1), and the locking tongue (5-1) is opened to lock the locking hook (6-1). When the swing door (1-1) is pushed or pulled, the locking tongue (5-1) hooks the locking hook (6-1) to make the shielding door (1-2) rotate synchronously; the pulling rope (5-3) drives the pulling handle (5-2) on the impact latch (5) to move through the guide wheel (5-4) for direction change.

[0027] The design concept of the present invention is:

[0028] 1. Select the angular door design: If traditional cross-shaped anti-tailgating rolling gates and front and rear door forms of anti-tailgating doors are selected, the two doors for entry and exit not only occupy a large area and have high costs, but also the courier's delivery cart and large express items cannot enter the warehouse. In order to significantly reduce costs and reduce the floor area, and also considering improving the pick-up speed during the peak pick-up period at night in the intelligent warehouse, two doors for entry and exit need to be designed. Based on the evaluation of the current social civilization level and the pick-up express item scenarios, the present invention does not adopt the absolute anti-tailgating function design, but adopts the relative anti-tailgating function design of the angular door + internal door barrier and external door barrier, which greatly increases the difficulty for two adults to enter and exit the door simultaneously, and also takes into account the humanized design that 1 adult + 1 child can enter and exit the door simultaneously on the premise of overcoming congestion;

[0029] 2. Manual push-pull type door opening design: Adopt the angular door design of manual push-pull by personnel and automatic door closing by the door closer. Compared with the electric door design, it has a lower cost and does not require the anti-pinch function of the electric door, and the entry and exit time is shortened to within 3 seconds.

[0030] 3. Anti-tailgating access control system design: Adopt a power door locking device to receive the system door opening command to control the opening and closing of the angular door. The main control machine receives the induction signal of the sensor to command and control a power locking gear device and a power anti-locking gear device to lock a certain rotation direction of a gear, so as to control the rotation of the angular door in the opening or closing direction, and realize the anti-tailgating function.

[0031] 4. Angle door design with variable opening angle: In order to meet the needs of couriers pulling express trucks or carrying large express parcels into the door, the swing door and the shielding door of the corner door can be freely transformed from 90° to 180° through a set of hinges: insert a key into a button lock and rotate it, and the pull rope connected to the button lock pulls the handle on the impact-type buckle lock connected to the other end through the guide wheel. The lock tongue on the impact-type buckle lock opens, and the lock hook on the fixed angle piece disengages from the lock tongue. The swing door and the shielding door are opened from 90° to 180° through a set of hinges; when the corner door is merged from 180° to 90°, the lock hook on a fixed angle piece of the swing door hits the lock tongue on the impact-type buckle lock of the shielding door, and the lock tongue opens and locks the lock hook, so that the swing door and the shielding door are connected to form a 90° angle door. When pushing or pulling the swing door or the shielding door, the other door rotates synchronously.

[0032] The advantages and beneficial effects of the present invention are

[0033] 1. The present invention adopts a corner door design with a small footprint and low manufacturing cost: The entry and exit corner doors of the present invention are designed and used on the smart express storage and retrieval warehouse, which occupies a small area (each corner door occupies only 0.8 square meters). This breaks through the promotion bottleneck of having no place to place smart express storage and retrieval warehouses due to the small open space in the community. The smart express storage and retrieval warehouse has increased the storage capacity several times compared with smart express cabinets with the same footprint.

[0034] 2. The anti-tailing design of the door closer + electric locking gear device + electric stopping gear device on the corner door of the present invention is simple and low in cost: a main control computer (NK643-2 Core 3-10th generation industrial control computer can be selected) is used to receive the sensor sensing signal and send instructions to control an electric locking gear device and an electric stopping gear device to lock a certain rotation direction of a gear to control the rotation of the corner door in the opening or closing direction, thereby realizing the anti-tailing function. Not only is the design simple and the manufacturing and operation and maintenance costs are low, but the door opening and closing speed is faster than that of an electric door, which can speed up the user's pickup speed into the warehouse, and solves the problem that online grocery shopping cannot be fully promoted in the future due to the long queue time for picking up vegetables during the evening peak, and provides the necessary conditions for the future development of online shopping from elite consumption to inclusive consumption, so that the dividends of Internet technology can benefit every citizen in the community.

[0035] 3. The corner door design of the present invention can change the opening degree to eliminate the restriction of express cabinets on the size of express parcels: the swing door and the blocking door of the corner door can be freely changed from 90° to 180° through a set of hinges, which allows couriers to pull express carts or lift large express parcels into the warehouse freely. The express parcels are placed in order on the shelf, which can meet the intelligent storage and retrieval of online shopping goods of various categories and sizes for users, and promote the online sales of large-volume fast-moving consumer goods such as large-package napkins, whole boxes of beer, whole boxes of mineral water, mats, clothes racks, general furniture, etc.

[0036] 4. The present invention uses a smart warehouse to store and retrieve express parcels. The warehouse has a large space and only needs to be equipped with air conditioners to store and retrieve fresh fruits and vegetables. Compared with the refrigeration costs of smart refrigerated express cabinets, the investment and operating costs of the smart warehouse of the present invention are lower. Smart refrigerated express cabinets cannot solve the problem of whether users can store the size and quantity of fresh fruits and vegetables they purchase daily. The present invention places fresh fruits and vegetables on the shelves in order, and does not impose too many restrictions on the size of fresh fruits and vegetables and the number of parcels.

[0037] 5. The present invention can meet the 24-hour intelligent access needs of users for online shopping, and can also meet the daily evening grocery shopping needs of users in industries such as beauty salons who cannot work from 8 am to 5 pm. BRIEF DESCRIPTION OF THE DRAWINGS

The lock gear assembly 2 and the power door locking device 3 (electromagnet can be selected) are installed on the door frame. As Figure 1 and Figure 21 , Figure 22 As shown in the figure, the door closer device 4 (built-in floor spring door closer can be selected) is installed in the lower door frame or buried underground; or as Figure 5 , Figure 9 As shown in the figure, the door closer device 4 (external door closer) is installed on the door frame, and one end of the arm of the external door closer is installed on the corner door 1, or the door closer device 4 (external door closer) is installed on the corner door 1, and one end of the arm of the external door closer is installed on the door frame. As Figure 5 As shown in the figure, the door shaft 11 is installed on the lower door frame; or as [[ID=http: / / www.wipo.int / pctdb / en / wo.jsp?wo=2013174784&IA=CN201310278772&DISPLAY=DESC&CURRENT=yes46]] Figure 9 As shown in the figure, the hinge joint 9 is installed between one side edge of the corner door 1 and the corresponding door frame. As Figures 1 - 5 , Figure 14 and Figure 21 , Figure 22 As shown in the figure, connecting members 1-1-1 are respectively provided on the upper and lower door edges of the corner door 1. As Figures 1 - 9 and Figure 21 , Figure 22 , Figure 17 , Figure 18 As shown in the figure, the sensor C is installed on the corner door 1, or can be installed above the entrance and exit or on the wall at the entrance.

[0078] As Figures 1 - 16 and Figure 21 、 Figure 22 shown, the locking tooth assembly 2 includes an electric locking tooth device 2-1 (electromagnet can be selected), a gear 2-2, and a shaft rod 2-3. The electric locking tooth device 2-1 (electromagnet can be selected) is installed on the upper door frame. There is a shaft hole 2-3-4 in the center of the gear 2-2. There are two fixing parts 2-3-3 respectively fixedly installed at the upper and lower ends of the upper door frame. The shaft rod 2-3 sequentially passes through the round holes on the lower fixing part 2-3-3 of the upper door frame, the shaft hole 2-3-4 in the center of the gear 2-2, and the round holes on the upper fixing part 2-3-3 of the upper door frame. The shaft rod 2-3 is fixedly connected to the gear 2-2 and rotates synchronously between the two fixing parts 2-3-3. There is a connecting head 2-3-1 at the lower end of the shaft rod 2-3. As Figures 1 - 5 、 Figure 14 and Figure 21 、 Figure 22 shown, there is a connecting part 1-1-1 on each of the upper and lower door edges of the side door 1's swing door 1-1. As Figures 1 - 4 、 Figure 14 and Figure 21 、 Figure 22 shown, the shaft rod 2-3 serves as the upper door hinge of the swing door 1-1 of the side door 1, and the door closer shaft head 4-1 on the door closer device 4 (built-in floor spring door closer can be selected) serves as the lower door hinge of the swing door 1-1 of the side door 1. The upper door hinge and the lower door hinge are respectively connected to the connecting parts 1-1-1 on the upper and lower door edges of the swing door 1-1, so that the swing door 1-1 of the side door 1 can drive the shielding door 1-2 to rotate and open and close along the upper and lower door frames, realizing the synchronous rotation, stop, opening and closing of the shaft rod 2-3 and the gear 2-2 with the side door 1. Or as Figures 5 - 8 and Figure 14 shown, an external door closer device 4 is selected. The shaft rod 2-3 serves as the upper door hinge of the swing door 1-1 of the side door 1, and the door shaft 11 serves as the lower door hinge of the swing door 1-1 of the side door 1. The upper door hinge and the lower door hinge are respectively connected to the connecting parts 1-1-1 on the upper and lower door edges of the swing door 1-1, so that the swing door 1-1 of the side door 1 can drive the shielding door 1-2 to rotate and open and close along the upper and lower door frames, realizing the synchronous rotation, stop, opening and closing of the shaft rod 2-3 and the gear 2-2 with the side door 1. Or as Figure 9 、 Figure 10 、 Figure 11As shown, on the door closer device 4 (external door closer), there is a rotating shaft 4-2. A connecting piece 4-3 is connected between the rotating shaft 4-2 and the connecting head 2-3-1 below the shaft rod 2-3. A hinge hinge 9 is installed between the side edge of the swing door 1-1 of the corner door 1 and the corresponding door frame, so that the swing door 1-1 of the corner door 1 drives the shielding door 1-2 to rotate and open / close along the upper and lower door frames. When the swing door 1-1 of the corner door 1 rotates to open / close, it drives the swing of the arm of the door closer device 4 (external door closer), causing the rotating shaft 4-2 to rotate synchronously. Through the connecting piece 4-3 connected thereto, the shaft rod 2-3 and the gear 2-2 can rotate, stop, open, and close synchronously with the corner door 1.

[0079] As Figures 1 - 5 、 Figure 14 and Figure 21 、 Figure 22 shown, on the connecting piece 1-1-1 at the upper and lower side edges of the swing door 1-1 of the corner door 1, there is a connection port 1-1-2. The connecting head 2-3-1 below the shaft rod 2-3 is inserted and connected to the connection port 1-1-2 on the connecting piece 1-1-1 at the upper side edge of the swing door 1-1 of the corner door 1; As Figures 1 - 4 and Figure 21 、 Figure 22 shown, the door closer shaft head 4-1 on the door closer device 4 (selectable built-in floor spring door closer) is inserted and connected to the connection port 1-1-2 of the connecting piece 1-1-1 at the lower side edge of the swing door 1-1 of the corner door 1, or as Figures 5 - 8 shown, the door shaft 11 is inserted and connected to the connection port 1-1-2 of the connecting piece 1-1-1 at the lower side edge of the swing door 1-1 of the corner door 1.

[0080] As Figure 16 、 Figure 15 shown, on the electric lock tooth device 2-1, there is a lock tooth bolt 2-1-1.

[0081] As Figures 12 - 13 、 Figure 19 、 Figure 20 shown, the lock tooth assembly 2 further includes an electric tooth stopping device 2-4 (selectable electromagnet). The electric tooth stopping device 2-4 is installed on the upper door frame, and the electric tooth stopping device 2-4 is connected with a tooth stopping bolt 2-4-1.

[0082] As Figure 21 、 Figure 22 、 Figure 23 、 Figure 24As shown in the figure, the side-hung door 1-1 and the shielding door 1-2 on the corner door 1 are connected at a 90-degree angle. The connection method can adopt a set of hinges 8. There is a fixed angle member 6 between the side-hung door 1-1 and the shielding door 1-2. There is an impact latch 5 and a knob lock 7 (a triangular lock can be selected) on the corner door 1. There is a lock hook 6-1 on the fixed angle member 6, a lock tongue 5-1 and a pull handle 5-2 on the impact latch 5. One end of a pull rope 5-3 is connected to the pull handle 5-2, and the other end of the pull rope 5-3 is connected to the knob lock 7 (a triangular lock can be selected). The fixed angle member 6 is installed on the side-hung door 1-1, and the impact latch 5 and the knob lock 7 (a triangular lock can be selected) are installed on the shielding door 1-2. Or, the fixed angle member 6 is installed on the shielding door 1-2, and the impact latch 5 and the knob lock 7 (a triangular lock can be selected) are installed on the side-hung door 1-1.

[0083] As Figure 23 , Figure 24 shown in the figure, a guide wheel 5-4 is provided on the corner door 1. The pull rope 5-3 bypasses the guide wheel 5-4, and the pull rope 5-3 changes direction through the guide wheel 5-4, so that the pull handle 5-2 and the knob lock 7 can be linked.

[0084] As Figure 25 shown in the figure, two corner doors 1 are installed on the front of the express delivery storage bin 101. A storage shelf 102 is provided in the express delivery storage bin 101, and the express delivery 103 is placed on the storage shelf 102. An inner door barrier 1-3 and an outer door barrier 1-4 are provided on the opening side of the side-hung door 1-1 on the corner door 1. The door closer device on the door frame of the side-hung door 1-1 selects an external door closer.

[0085] As Figure 11 , Figure 14 shown in the figure, a square column 2-3-2 is provided in the middle of the shaft rod 2-3. There is a square shaft hole 2-3-4 in the center of the gear 2-2. The square column 2-3-2 on the shaft rod 2-3 passes through and remains at the square shaft hole 2-3-4, so that the shaft rod 2-3 and the gear 2-2 rotate synchronously.

[0086] As Figures 1 - 26 , Figure 17 , Figure 18 shown in the figure, the specific usage method of the device of the present invention is as follows:

[0087] I. When the device of the present invention is used as an entrance door:

[0088] 1. Prevent people outside the door from following in after entering the door

[0089] As Figures 1 - 9 , Figure 21 , Figure 25 , Figure 17 , Figure 18As shown in the figure, when a person (user, courier) enters the door, they open the mobile APP and pass the identification verification of the main control machine (NK643-2 Core 3-10 industrial control machine can be selected) through methods such as scanning the code and face recognition, and the main control machine does not receive the human body induction signal or human figure image induction signal of sensor C (human body induction sensor or human figure image sensor). The main control machine (NK643-2 Core 3-10 industrial control machine can be selected) issues an opening instruction, and the electric door locking device 3 (electromagnet can be selected) is opened (the lock head 3-1 disengages from the lock hole 3-2), and the corner door 1 is opened. When the person pulls open the swing door 1-1 of the corner door 1 to enter, sensor C (human body induction sensor or human figure image sensor) senses the human body induction signal or human figure image induction signal, the main control machine receives the signal and issues an instruction, and the electric lock tooth device 2-1 (electromagnet can be selected) on the lock tooth assembly 2 acts, and the lock tooth bolt 2-1-1 on the electric lock tooth device 2-1 (as Figure 16 shown) changes from the retracted state to the extended state (as Figure 15 shown), locking the opening rotation direction of the gear 2-2 and the shaft rod 2-3. As Figures 1 - 5 , Figure 14 and Figure 21 shown, since the connecting head 2-3-1 at the lower end of the shaft rod 2-3 is inserted into the connecting port 1-1-2 on the connecting part 1-1-1, the swing door 1-1 of the corner door 1 is synchronously locked in the opening rotation direction, and the corner door 1 can only rotate in the closing direction under the action of the built-in or external door closer device 4 and cannot be pulled open, preventing someone from pulling the door and following in when the swing door 1-1 of the corner door 1 is not closed to the initial closed position. As Figure 9 , Figure 10 , Figure 11 shown, since the connecting head 2-3-1 at the lower end of the shaft rod 2-3 is inserted into the upper interface 4-3-1 of the connecting part 4-3, and the rotating shaft 4-2 on the door closer device 4 (external door closer) is inserted into the lower interface 4-3-2 of the connecting part 4-3, locking the opening rotation direction of the rotating shaft 4-2, the door closer device 4 (external door closer) and the swing door 1-1 of the corner door 1 are synchronously locked in the opening rotation direction, and the corner door 1 can only rotate in the closing direction under the action of the door closer device 4 (external door closer) and cannot be pulled open, preventing someone from pulling the door and following in when the swing door 1-1 of the corner door 1 is not closed to the initial closed position or the main control machine does not issue an opening instruction again.

[0090] 2. Prevent people inside the door from following out when entering the door

[0091] As Figures 1 - 9 , Figure 21 , Figure 25 , Figure 17 , Figure 18As shown, when a person (user, courier) enters the door, they open the mobile APP and pass the identification verification of the main control machine (the NK643-2 Core 3-10 industrial control machine can be selected) through methods such as scanning the code and face recognition, and the main control machine receives the human body induction signal or human form image induction signal of sensor C (human body induction sensor or human form image sensor). The main control machine (the NK643-2 Core 3-10 industrial control machine can be selected) does not issue an opening instruction, the electric door locking device 3 (the electromagnet can be selected) does not act, and the corner door 1 cannot be opened; when sensor C (human body induction sensor or human form image sensor) does not sense the human body induction signal or human form image induction signal inside the door, the main control machine issues an opening instruction, and the electric door locking device 3 (the electromagnet can be selected) is opened, so that the lock head 3-1 disengages from the lock hole 3-2; just after the corner door 1 is opened, sensor C (human body induction sensor or human form image sensor) senses the human body induction signal or human form image induction signal, the main control machine receives the signal and issues an instruction, and the electric lock tooth device 2-1 (the electromagnet can be selected) on the lock tooth assembly 2 acts, and the lock tooth bolt 2-1-1 (as Figure 16 shown) changes from the retracted state to the extended state (as Figure 15 shown), locking the opening rotation direction of the gear 2-2 and the shaft rod 2-3. As Figures 1 - 5 , Figure 14 and Figure 21 shown, since the connecting head 2-3-1 at the lower end of the shaft rod 2-3 is inserted into the connecting port 1-1-2 on the connecting piece 1-1-1, the rotation of the side-hung door 1-1 of the corner door 1 in the opening direction is synchronously locked, and the corner door 1 can only rotate in the closing direction under the action of the built-in or external door closer device 4 and cannot be pulled open, preventing someone from pushing the door out from the inside when the side-hung door 1-1 of the corner door 1 has just been opened or has not been closed to the initial closed position. As Figure 9 , Figure 10 , Figure 11 shown, since the connecting head 2-3-1 at the lower end of the shaft rod 2-3 is inserted into the upper interface 4-3-1 of the connecting piece 4-3, and the rotating shaft 4-2 on the door closer device 4 (external door closer) is inserted into the lower interface 4-3-2 of the connecting piece 4-3, the opening rotation direction of the rotating shaft 4-2 is locked, so that the door closer device 4 (external door closer) and the side-hung door 1-1 of the corner door 1 are synchronously locked in the opening rotation direction, and the corner door 1 can only rotate in the closing direction under the action of the door closer device 4 (external door closer) and cannot be pulled open, preventing someone from pushing the door out from the inside when the side-hung door 1-1 of the corner door 1 has just been opened or has not been closed to the initial closed position.

[0092] As Figures 1 - 9 , Figure 21As shown in the figure, when the swing door 1-1 of the corner door 1 is closed to the initial closed position under the action of the built-in or external door closer device 4, the electric door locking device 3 (electromagnet can be selected) is closed, so that the lock head 3-1 is inserted into the lock hole 3-2, and the corner door 1 is closed; the main control machine issues an instruction, and the electric lock tooth device 2-1 (electromagnet can be selected) on the electric lock tooth assembly 2 acts, and the lock tooth bolt 2-1-1 on the electric lock tooth device 2-1 returns from the extended state (as shown in Figure 15 shown) to the retracted state (as shown in Figure 16 shown).

[0093] II. When the device of the present invention is used for going out:

[0094] 1. Prevent people inside the door from following out when going out

[0095] As shown in Figures 1 - 9 , Figure 21 , Figure 25 , Figure 17 , Figure 18 shown, when a person (user, courier) goes out, open the mobile APP and submit an opening application to the main control machine (NK643-2 Core 3-10 industrial control machine can be selected) through methods such as scanning code and face recognition. When the main control machine receives the application and also receives the human body induction signal or humanoid image induction signal of sensor C (human body induction sensor or humanoid image sensor), the main control machine issues an opening instruction. When sensor C (human body induction sensor or humanoid image sensor) senses the human body induction signal or humanoid image induction signal, the main control machine issues an opening instruction, and the electric door locking device 3 (electromagnet can be selected) is opened (the lock head 3-1 is disengaged from the lock hole 3-2), and the corner door 1 is opened; after the person pushes open the swing door 1-1 of the corner door 1 and goes out, when the corner door 1 rotates a certain angle (30-45°) in the closing direction under the action of the built-in or external door closer device 4, there is no one in the area formed by the swing door 1-1 of the corner door 1, the shielding door 1-2 and the inner door railing 1-3 and the outer door railing 1-4, that is, at this time, sensor C (human body induction sensor or humanoid image sensor) cannot sense the human body induction signal or humanoid image induction signal, the main control machine issues an instruction, and the electric lock tooth device 2-1 (electromagnet can be selected) on the lock tooth assembly 2 acts, and the lock tooth bolt 2-1-1 (as shown in Figure 16 shown) changes from the retracted state to the extended state (as shown in Figure 15 shown), locking the rotation direction of the gear 2-2 and the shaft rod 2-3 for pushing open the door. As shown in Figures 1 - 5 , Figure 14 and Figure 21As shown, since the connector 2-3-1 at the lower end of the shaft rod 2-3 is inserted into the connection port 1-1-2 on the connector 1-1-1, the swing door 1-1 of the corner door 1 is synchronously locked against rotation in the door-opening direction. The corner door 1 can only rotate in the closing direction under the action of the built-in or external door closer device 4 and cannot be pushed open, preventing someone from pushing the door open from the inside when the swing door 1-1 of the corner door 1 is not closed to the initial closed position or the main control unit does not issue another door-opening command. As Figure 9 、 Figure 10 、 Figure 11 As shown, since the connector 2-3-1 at the lower end of the shaft rod 2-3 is inserted into the upper interface 4-3-1 of the connecting member 4-3, and the rotating shaft 4-2 of the door closer device 4 (external door closer) is inserted into the lower interface 4-3-2 of the connecting member 4-3, the rotation of the rotating shaft 4-2 in the door-opening direction is locked, resulting in the synchronous locking of the rotation of the door closer device 4 (external door closer) and the swing door 1-1 of the corner door 1 in the door-opening direction. The corner door 1 can only rotate in the closing direction under the action of the door closer device 4 (external door closer) and cannot be pushed open, preventing someone from pushing the door open from the inside when the swing door 1-1 of the corner door 1 is not closed to the initial closed position or the main control unit does not issue another door-opening command.

[0096] As Figures 1 - 9 、 Figure 21 As shown, when the swing door 1-1 of the corner door 1 is closed to the initial position under the action of the built-in or external door closer device 4, the electric door locking device 3 (electromagnet can be selected) operates, and the lock head 3-1 is inserted into the lock hole 3-2, closing the corner door 1. The main control unit issues a command, and the electric lock gear device 2-1 (electromagnet can be selected) operates.

[0097] 2. Prevent people outside from following in after going out

[0098] As Figure 12 、 Figure 13 、 Figure 19 、 Figure 20 、 Figure 25 、 Figure 17 、 Figure 18As shown, when a person (user, courier) goes out, they open the mobile APP and submit a door opening application to the main control unit (NK643-2 Core 3-10 industrial control unit can be selected) through methods such as scanning the code and face recognition. When the main control unit receives the application and also receives the human body induction signal or humanoid image induction signal from sensor C (human body induction sensor or humanoid image sensor), the main control unit issues a door opening instruction. Sensor C (human body induction sensor or humanoid image sensor) senses the human body induction signal or humanoid image induction signal, and the main control unit issues a door opening instruction. The electric door locking device 3 (electromagnet can be selected) is opened (the lock head 3-1 disengages from the lock hole 3-2), and the corner door 1 is opened. After the person pushes open the swing door 1-1 of the corner door 1 and goes out, when the corner door 1 rotates a certain angle (30 - 45°) in the closing direction under the action of the built-in or external door closer device 4, if there is someone (someone follows) in the area formed by the swing door 1-1 and the shielding door 1-2 of the corner door 1 and the inner door barrier 1-3 and the outer door barrier 1-4, that is, at this time, when sensor C (human body induction sensor or humanoid image sensor) senses the human body induction signal or humanoid image induction signal, the main control unit issues an instruction, and the electric stop gear device 2-4 (electromagnet can be selected) on the door frame acts, and the stop gear bolt 2-4-1 on the electric stop gear device 2-4 changes from the retracted state (as shown in Figure 19 shown) to the extended state (as shown in Figure 20 shown), locking the closing rotation direction of the gear 2-2 and the shaft rod 2-3. As shown in Figure 12 , Figure 13 and Figure 14 shown, since the connecting head 2-3-1 at the lower end of the shaft rod 2-3 is inserted into the connecting port 1-1-2 on the connecting member 1-1-1, the swing door 1-1 of the corner door 1 is synchronously locked in the closing rotation direction. The person (the following person) in the area formed by the swing door 1-1 and the shielding door 1-2 of the corner door 1 and the inner door barrier 1-3 and the outer door barrier 1-4 can only push the swing door 1-1 of the corner door 1 in the opening direction to leave. After the following person leaves, when sensor C (human body induction sensor or humanoid image sensor) in the area formed by the swing door 1-1 and the shielding door 1-2 of the corner door 1 and the inner door barrier 1-3 and the outer door barrier 1-4 does not sense the human body induction signal or humanoid image induction signal, the main control unit issues an instruction, and the electric stop gear device 2-4 (electromagnet can be selected) on the door frame acts, and the stop gear bolt 2-4-1 on the electric stop gear device 2-4 changes from the extended state (as shown in Figure 20 shown) to the retracted state (as shown in Figure 19 shown), and the system continues to execute the "preventing people inside the door from following out when going out" program action.

[0099] III. Opening and closing process of the swing door 1-1 and the shielding door 1-2 of the corner door 1 of the present invention:

[0100] When the courier pulls a cart to deliver goods into the warehouse (such as the express storage warehouse 101), when the side door 1 needs to open the French door 1-1 and the baffle door 1-2 from 90° to 180°, as Figure 21 , Figure 22 , Figure 23 , Figure 24 shown, insert the key into the button lock 7 (a triangular lock can be selected) and rotate it. The pull rope 5-3 connected to it drives the handle 5-2 on the impact latch 5 at the other end to move, so that the locking tongue 5-1 on the impact latch 5 is opened, and the locking hook 6-1 on the fixed angle piece 6 is disengaged from the locking tongue 5-1. The French door 1-1 and the baffle door 1-2 are opened from 90° to 180° through a set of hinges 8; when the French door 1-1 and the baffle door 1-2 are closed from 180° to 90°, the locking hook 6-1 impacts the locking tongue 5-1, and the locking tongue 5-1 is opened to lock the locking hook 6-1. When pushing and pulling the French door 1-1, the locking tongue 5-1 hooks the locking hook 6-1 to make the baffle door 1-2 rotate synchronously; the pull rope 5-3 can drive the handle 5-2 on the impact latch 5 to move through the deflection of the guide wheel 5-4.

8. A method for using the anti-tailgating corner door control device according to any one of claims 1 to 7, characterized in that, The steps include: (1) When used as an entrance door: 1) To prevent people outside the door from following in after entering the door. When a person enters the door, they open the mobile APP and pass through the main control unit for identification and verification by methods such as scanning a code or face recognition. If the main control unit does not receive a human body induction signal or a humanoid image induction signal from the sensor (C), the main control unit issues an opening instruction, the electric door locking device (3) is activated, the lock head (3-1) disengages from the lock hole (3-2), and the corner door (1) opens. When the person pulls open the swing door (1-1) of the corner door (1) to enter, the sensor (C) senses a human body induction signal or a humanoid image induction signal. The main control unit receives the signal and issues an instruction, and the electric lock tooth device (2-1) on the lock tooth assembly (2) operates. The lock tooth bolt (2-1-1) on the electric lock tooth device (2-1) changes from the retracted state to the extended state, locking the opening rotation direction of the gear (2-2) and the shaft rod (2-3). Since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connecting port 1-1-2 on the connecting part (1-1-1), the rotation of the corner door (1) in the opening direction is synchronously locked, and the corner door (1) can only rotate in the closing direction under the action of the built-in or external door closer device (4) and cannot be pulled open. This prevents the swing door (1-1) of the corner door (1) from not being closed to the initial closed position and someone from pulling the door outside to follow in when the main control unit does not issue an opening instruction again. Since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the upper interface 4-3-1 of the connecting part 4-3, and the rotating shaft (4-2) of the external door closer device (4) is inserted into the lower interface 4-3-2 of the connecting part 4-3, locking the opening rotation direction of the rotating shaft (a), the external door closer device (4) and the corner door (1) are synchronously locked in the opening rotation direction. The corner door (1) can only rotate in the closing direction under the action of the external door closer device (4) and cannot be pulled open, preventing the swing door (1-1) of the corner door (1) from not being closed to the initial closed position and someone from pulling the door outside to follow in when the main control unit does not issue an opening instruction again. (2) Prevent people inside the door from following out when entering the door. When people enter the door, they open the mobile APP and pass through the main control machine for identification and verification through methods such as scanning codes or face recognition. If there is someone inside the door, the main control machine receives the human body induction signal or humanoid image induction signal from the sensor (C), and the main control machine does not issue an opening instruction. The electric door locking device (3) does not act, and the corner door (1) cannot be opened. When the sensor (C) does not sense the human body induction signal or humanoid image induction signal inside the door, the main control machine issues an opening instruction, the electric door locking device (3) is opened, the lock head (3-1) disengages from the lock hole (3-2). Just after the corner door (1) is opened, if someone comes inside the door, the sensor (C) senses the human body induction signal or humanoid image induction signal, the main control machine receives the signal and issues an instruction, and the electric lock tooth device (2-1) on the lock tooth assembly (2) acts, and the lock tooth bolt (2-1-1) changes from the retracted state to the extended state, locking the opening rotation direction of the gear (2-2) and the shaft rod (2-3). Since the connecting head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connecting port 1-1-2 on the connecting piece (1-1-1), the rotation of the corner door (1) in the opening direction is synchronously locked, and the corner door (1) can only rotate in the closing direction under the action of the built-in or external door closer device (4) and cannot be pulled open, preventing someone from pushing the door out from the inside when the swing door (1-1) of the corner door (1) is just opened or not closed to the initial closed position. Since the connecting head (2-3-1) at the lower end of the shaft rod (2- ​ 1) Prevent people inside the door from following others out when going out. When a person goes out, they open the mobile APP and submit a door opening application to the main control unit through methods such as scanning a code or face recognition. After receiving the application and the human body induction signal or humanoid image induction signal from the sensor (C), the main control unit issues a door opening command. The electric door locking device (3) is activated, the lock head (3-1) disengages from the lock hole (3-2), and the corner door (1) opens. After the person pushes open the swing door (1-1) of the corner door (1) and goes out, when the corner door (1) rotates 30-45° in the closing direction under the action of the built-in or external door closer device (4), there is no one in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4, that is, at this time the sensor (C) cannot sense the human body induction signal or the humanoid image induction signal. The main control unit issues a command, and the electric lock tooth device (2-1) on the lock tooth assembly (2) operates, and the lock tooth bolt (2-1-1) changes from the retracted state to the extended state, locking the opening rotation direction of the gear (2-2) and the shaft rod (2-3); since the connection head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connection port 1-1-2 on the connecting member (1-1-1), the rotation of the corner door (1) in the opening direction is synchronously locked, and the corner door (1) can only rotate in the closing direction under the action of the built-in or external door closer device (4) and cannot be pushed open, preventing someone from pushing the swing door (1-1) of the corner door (1) out when it is not closed to the initial closed position or the main control unit does not issue a door opening command again; since the connection head (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the upper interface 4-3-1 of the connecting member 4-3, and the rotating shaft (4-2) of the external door closer device (4) is inserted into the lower interface 4-3-2 of the connecting member 4-3, the opening rotation direction of the rotating shaft (4-2) is locked, resulting in the synchronous locking of the rotation of the external door closer device (4) and the corner door (1) in the opening direction. The corner door (1) can only rotate in the closing direction under the action of the external door closer device (4) and cannot be pushed open, preventing someone from pushing the swing door (1-1) of the corner door (1) out when it is not closed to the initial closed position or the main control unit does not issue a door opening command again; when the corner door (1) closes to the initial position under the action of the built-in or external door closer device (4), the electric door locking device (3) operates, the lock head 3-1 is inserted into the lock hole 3-2, and the corner door (1) closes; the main control unit issues a command, and the electric lock tooth device (2-1) operates, and the lock tooth bolt (2-1-1) on the electric lock tooth device (2-1) returns from the extended state to the retracted state; 2) Prevent people outside from following in after going out. When a person goes out, they open the mobile APP and submit a door opening application to the main control unit through methods such as scanning a code or face recognition. When the main control unit receives the application and also receives the human body induction signal or humanoid image induction signal from the sensor (C), the main control unit issues a door opening command, and the electric door locking device (3) is activated. The lock head (3-1) disengages from the lock hole (3-2), and the corner door (1) opens. After the person pushes open the swing door (1-1) of the corner door (1) and goes out, when the corner door (1) rotates 30 - 45° in the closing direction under the action of the built-in or external door closer device (4), if there is someone in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4, that is, when the sensor (C) senses the human body induction signal or the humanoid image induction signal at this time, the main control unit issues an instruction, and the electric stop gear device (2-4) on the door frame operates. The stop gear bolt (2-4-1) on the electric stop gear device (2-4) changes from the retracted state to the extended state, locking the closing rotation direction of the gear (2-2) and the shaft rod (2-3). Since the connector (2-3-1) at the lower end of the shaft rod (2-3) is inserted into the connection port 1-1-2 on the connector (1-1-1), the rotation of the corner door (1) in the closing direction is synchronously locked. People in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4 can only push the swing door (1-1) of the corner door (1) in the opening direction to leave. After the person who wants to follow leaves, the sensor (C) in the area formed by the swing door (1-1) and the shielding door (1-2) of the corner door (1) and the inner door barrier 1-3 and the outer door barrier 1-4 does not sense the human body induction signal or the humanoid image induction signal. The main control unit issues an instruction, and the electric stop gear device (2-4) on the door frame operates. After the stop gear bolt (2-4-1) on the electric stop gear device (2-4) changes from the extended state to the retracted state, the system continues to execute the program action of "preventing people inside from following out after going out".
