Description

Technical Field

[0001] The utility model relates to the technical field of door access control systems, in particular to a security device facility. Background Art

[0002] Access control refers to the prohibition of door permissions. In the field of intelligent facilities, it is a management method to identify the access permissions of different pedestrians and vehicles. Access control achieves the purpose of security defense by managing access permissions. Therefore, in daily life, especially in the security of shopping malls and office areas of office buildings, security access control devices are very common.

[0003] Existing access control facilities have certain drawbacks. Some access control doors on the market are opened and closed from the inside and outside, which results in a large door rotation radius and low utilization of pedestrian passage space. In some occasions, only one access control can be set up in the pedestrian passage space, and people entering and leaving the passage all pass through the same access control. Therefore, the access control needs to be designed with two opening and closing directions, which is easy to conflict with pedestrians, posing a safety hazard to pedestrians and the risk of damaging the device facilities. For this reason, it is necessary to design a security access control device to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a security access control device to solve the problem that the access control device proposed in the above background technology has low space utilization and is prone to conflict with pedestrians during use, posing a safety hazard to pedestrians and damaging the device facilities.

[0005] The above technical objective is achieved through the following technical scheme, including two access control boxes arranged horizontally opposite to each other, a switch module is fixedly installed on the outer surface of the upper end of the access control box, a rotating shaft is fixed in the middle of the opposite side of the two access control boxes, the rotating shaft is rotatably connected to the main gear lever, the rotating shaft is horizontally arranged, and the rotation direction of the main gear lever is vertical, the main gear lever partially extends into the access control box, and the part of the main gear lever extending into the access control box is connected to an electromagnetic suction device for driving the gear lever to move in a vertical direction, and the switch module signal is connected to the electromagnetic suction device for controlling the power on and off of the electromagnetic suction device.

[0006] By adopting the above technical solution, when the switch module detects that the door needs to be opened due to the access permission of pedestrians, the door opening signal is transmitted to the electromagnetic suction device. The electromagnetic suction device receives the signal and is powered on and drives the shaft to start rotating. After the main lever rotates and drops to a suitable position with the shaft, the access control passage is fully opened; after the pedestrian passes through the access control, the electromagnetic suction device is powered off and the shaft is reset. The access control device realizes the opening and closing of the passage in the above manner. Compared with the horizontal opening and closing, the vertical rotation opening and closing method of the door eliminates the horizontal rotation radius of the door, improves the space utilization rate when the access control door is opened, and reduces the possibility of conflict with pedestrians.

[0007] Optionally, each of the two access control boxes is provided with a set of wheel train devices, the electromagnetic suction device and the rotating shaft are connected through the wheel train device, the wheel train device is located above the electromagnetic suction device, the electromagnetic suction device includes an upper electromagnet sheet and a lower electromagnet sheet that attract each other in a vertical direction, the upper electromagnet sheet is fixedly connected to the wheel train device, and the lower electromagnet sheet is fixed to the access control box.

[0008] By adopting the above technical solution, when the access control device opens the door, the electromagnetic suction device is energized, and the upper and lower electromagnetic iron sheets in the vertical direction attract each other, driving the gear train device, which transmits power to the shaft, and the main lever connected to the shaft rotates and descends. Compared with the use of motor drive, the structure based on the electromagnetic suction device drive design can also realize the transmission and limit functions, and the method is relatively simple, efficient and feasible. At the same time, it can also reduce the noise caused by mechanical vibration caused by contact between components and extend the service life of the device.

[0009] Optionally, the wheel train device includes a movable pulley, a fixed pulley, and a wheel rope. The movable pulley is connected to the upper electromagnet sheet and can move up and down in the vertical direction. The fixed pulley includes a first transmission shaft fixed in the access control box and a first rotating body sleeved on the first transmission shaft. The fixed pulley is located in the upper part of the access control box on the side of the passage. One end of the wheel rope is fixedly connected to an end of the main baffle bar extending into the access control box. The wheel rope starts from the main baffle bar, passes over the first rotating body and under the movable pulley in sequence, and is fixedly connected to the inner wall of the access control box away from the passage.

[0010] By adopting the above technical solution, since metal parts in the surrounding environment will affect the electromagnetic suction device, the electromagnetic suction device can be set at one end away from the pedestrian passage by designing the gear train device transmission to reduce the interference of the magnetic field. At the same time, due to the characteristics of the movable pulley device, the relative movement stroke of the upper electrode sheet and the lower electrode sheet required to control the stroke of the main gear lever can be shortened. When the upper electromagnet sheet and the lower electromagnet sheet are far apart, a larger magnetic field strength is required to generate suction. By controlling the maximum distance between the upper electromagnet sheet and the lower electromagnet sheet, the magnetic field strength in the environment can be reduced, ensuring the stability of the drive device and improving the safety of pedestrians.

[0011] Optionally, vertical guide rails are installed on both sides of the access control box body parallel to the main stop rod, and each of the two guide rails is slidably connected to a guide rail slider, and a second transmission shaft is fixedly connected between the two guide rail sliders, and the second transmission shaft is rotatably connected to the movable pulley.

[0012] By adopting the above technical solution, due to the long-term use of the device, the tension of the wheel rope will change, and the electromagnet sheet will have a magnetization effect, which will cause the movable pulley to shift from its original position. By connecting the movable pulley with a guide rail arranged in the vertical direction, the movable pulley can be limited to ensure the stability of the wheel system device.

[0013] Optionally, a fan-shaped shielding cloth is fixedly connected below the main shielding rod.

[0014] By adopting the above technical solution, when the access control is closed, the shielding cloth under the main barrier can expand the shielding area of ​​the pedestrian passage, reduce the possibility of children or other objects passing from below, and improve the reliability and safety of the access control device.

[0015] Optionally, the rotating shaft is hinged to a plurality of shielding rods having the same shape and specification as the main shielding rod, and the main shielding rod and the shielding rod are fixedly connected by the shielding cloth.

[0016] By adopting the above technical solution, since there may be other interference factors such as wind fields in the surrounding environment of the access control device, the shielding rod connected to the main shielding rod and the shielding cloth can enhance the interference of the device to certain forces in the channel direction and improve the stability of the access control device; the structure connecting the shielding rod and the shielding cloth ensures the foldability of the shielding cloth when opening the channel.

[0017] Optionally, a limit rod is fixed in the vertical direction below the main stop rod, and the limit rod is fixedly connected to the access control box.

[0018] By adopting the above technical solution, the limit rod can limit the main barrier rod through the shielding cloth, and can also ensure that the shielding cloth is tensioned to improve the stability of the device; the structural design of limiting the main barrier rod is simplified. In comparison, the overall structure is simpler after using the limit rod, and the limiting method is feasible and efficient.

[0019] Optionally, the side walls of the two access control boxes are each provided with a storage groove for the main barrier rod, the shielding cloth and the shielding rod to rotate into, and the storage groove is located below the rotating shaft.

[0020] By adopting the above technical solution, when the access control is opened, the main barrier bar, the shielding cloth and the shielding bar can be transferred into the storage slot, thereby reducing the passage space occupied by the box and the main barrier bar, improving the passage efficiency and widening the passage access size.

[0021] Optionally, a cushion layer is affixed to the outer surface of the main barrier rod, and reflective stickers are affixed to the outer surface of the cushion layer at even intervals.

[0022] By adopting the above technical solution, it can play the role of anti-collision and warning for pedestrians in the passage.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] The door of the present application is opened and closed by vertical rotation, which eliminates the lateral rotation radius of the door, improves the space utilization rate when the door is opened, and reduces the possibility of conflict with pedestrians in some occasions;

[0025] The present application adopts a folding mechanism to open and close the access control, reducing the volume of the access control box. The main barrier rod, the shielding cloth and the shielding rod are folded into the storage slot, saving the space occupied by the access control device in the passage and widening the access size of the passage.
