DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] See also Figures 1 to 12A rotary door control device comprises a revolving door overall frame 1, a driving assembly is installed on the inner side of the top of the revolving door overall frame 1, a rotating joint 2 is fixedly connected to the bottom of the driving assembly, a column 4 is installed below the rotating joint 2, four equally spaced outer door frames 5 are fixedly connected to the circumferential side of the column 4, a connecting plate 6 is hingedly connected to the side of the inner upper end of each outer door frame 5 away from the column 4, an inner door frame 7 hinged to the outer door frame 5 is installed below the connecting plate 6, a slide groove 19 is opened on the top of the connecting plate 6, a slider 18 is slidably connected inside the slide groove 19, a connecting block 17 is fixedly connected to the top of the slider 18, a threaded block 16 is fixedly connected to the end of the connecting block 17 away from the slider 18, a protective frame 8 is fixedly connected to the upper end of the column 4, a power assembly is fixedly connected to the middle position of the protective frame 8, both ends of the protective frame 8 are rotatably connected to screw rods 13, and each screw rod 13 is respectively threadedly connected to two threaded blocks 16.

[0033] In the rotary door access control device of the present invention, when an emergency occurs in a public place (such as a fire or earthquake) and the people in the public place need to be evacuated, the security personnel of the public place can start the power component, and the power component will drive the two screw rods 13 to rotate, and the threaded block 16 threadedly connected to the screw rod 13 will move in the direction away from the column 4. When the threaded block 16 moves, it will drive the slider 18 to move synchronously through the connecting block 17. When the slider 18 moves, it will drive the connecting plate 6 to rotate. Because the inner door frame 7 is installed together with the connecting plate 6, the connecting plate 6 will rotate with the inner door frame 7, so that the four inner door frames 7 are fully unfolded to form an evacuation channel (i.e. Figure 2 The state shown in the figure) is then displayed, and personnel can directly pass through the middle position to improve the evacuation efficiency of public places and reduce the difficulty of evacuation. In addition, the overall frame 1 of the revolving door and the driving assembly of the present invention are similar to the prior art, and a multifunctional revolving door structure disclosed in the patent with patent authorization announcement number CN210370381U is similar, so no further elaboration is made here.

[0034] As a preferred technical solution of the present invention, the power assembly includes a bidirectional motor 9, a remote control module 35, a battery 10, a wireless charging receiving module 11 and a wireless charging sending module 12. The wireless charging sending module 12 is fixedly connected to the top of the overall frame 1 of the revolving door, the bidirectional motor 9 is fixedly connected to the middle position of the protective frame 8, the output ends of the two ends of the bidirectional motor 9 are respectively fixedly connected to two screw rods 13, the remote control module 35 is fixedly connected to one side of the bidirectional motor 9, the battery 10 is fixedly connected to the top of the column 4, and the wireless charging receiving module 11 is fixedly connected to the top of the battery 10.

[0035] Specifically, when an emergency occurs in a public place, the public place will automatically start the emergency system, and the emergency system will start the bidirectional motor 9 through the remote control module 35. At this time, the battery 10 will provide power to the bidirectional motor 9, allowing the bidirectional motor 9 to drive the two screws 13 to rotate, thereby unfolding the inner door frame 7. In normal times (that is, when no emergency occurs), the battery 10 will be regularly charged through the wireless charging sending module 12 and the wireless charging receiving module 11 to power the bidirectional motor 9 in an emergency. In addition, since the bidirectional motor 9, the remote control module 35, the battery 10, the wireless charging receiving module 11 and the wireless charging sending module 12 are all existing mature products, they will not be elaborated on here.

[0036] As a preferred technical solution of the present invention, the column 4 is rotatably connected to the rotating joint 2, the end of the screw rod 13 close to the column 4 is threadedly connected to the threaded plate 14, the side of the threaded plate 14 close to the column 4 is fixedly connected to the plug block 15, and a slot 3 matching the plug block 15 is opened on the rotating joint 2, and the end of the plug block 15 away from the threaded plate 14 passes through the column 4 and extends into the slot 3.

[0037] Specifically, when the screw rod 13 rotates, the threaded plate 14 will drive the plug block 15 to move away from the column 4, thereby pulling the plug block 15 out of the slot 3. After the plug block 15 is pulled out, the column 4 and the rotary joint 2 will be in a rotational connection. If the revolving door stops in an emergency, the outer door frame 5 and the inner door frame 7 are just in the middle position of the evacuation passage (that is, the outer door frame 5 and the inner door frame 7 will affect the evacuation of personnel), the security personnel can directly manually push the outer door frame 5 to rotate, so that the outer door frame 5 and the inner door frame 7 rotate to both sides of the passage. Since the plug block 15 has been pulled out, the column 4 will not drive the rotary joint 2 and the driving component on the top of the rotary joint 2 to rotate when it rotates, so it is more labor-saving and convenient for the security personnel to push the outer door frame 5 to rotate.

[0038] As a preferred technical solution of the present invention, a plane is provided on a side of the rotary joint 2 close to the plug block 15 , and a chamfer is provided on a peripheral side of the plug block 15 away from the threaded plate 14 .

[0039] Specifically, after the disaster relief is completed, when the maintenance personnel reset the revolving door, the plane can clearly mark the position of the slot 3, which is convenient for aligning the plug block 15 with the slot 3. At the same time, the plug block 15 is chamfered to facilitate the insertion of the plug block 15 into the slot 3.

[0040] As a preferred technical solution of the present invention, a limiting groove 21 is provided on one side of the inner door frame 7 close to the column 4, a limiting column 22 is fixedly connected to the middle position of the limiting groove 21, and the upper end of the outer side of the limiting column 22 is slidably connected with a block 23 matching the limiting groove 21, a groove 20 matching the block 23 is provided at the bottom of the connecting plate 6 close to one end of the column 4, and a reset elastic member 24 is sleeved on the lower end of the limiting column 22.

[0041] Specifically, if the bidirectional motor 9 is damaged during long-term standby and is not discovered by the maintenance personnel, resulting in the inner door frame 7 being unable to automatically unfold to form an evacuation passage, the security personnel of the public place can slide the block 23 downward to disengage the block 23 from the slot 20, and then directly push the inner door frame 7 to rotate, thereby unfolding the inner door frame 7, so that the middle position of the revolving door forms an evacuation passage (such as Figure 3 The figure shows the state after the inner door frame 7 is manually unfolded), and this structure improves the stability and fault tolerance of the equipment.

[0042] As a preferred technical solution of the present invention, gripping grooves 25 are provided on both sides of the clamping block 23 , and a universal wheel 26 is rotatably connected to one end of the bottom of the inner door frame 7 close to the column 4 .

[0043] Specifically, it is more labor-saving and convenient to push the block 23 to slide through the gripping groove 25, and the universal wheel 26 provides support for the inner door frame 7, making it more convenient for the inner door frame 7 to rotate.

[0044] As a preferred technical solution of the present invention, a storage groove 27 is opened on one side of the column 4, and a guide plate 28 is provided inside the storage groove 27. The lower end of the guide plate 28 is hinged to the column 4, and the two ends of the guide plate 28 close to the column 4 are hinged to side panels 29, and the opposite surfaces of the two side panels 29 are fixed with elastic evacuation indicator cloths 30, and the lower ends of the opposite surfaces of the two side panels 29 are fixed with unfolding elastic members 31, and the other ends of the two unfolding elastic members 31 are fixed to the guide plate 28.

[0045] Specifically, after the inner door frame 7 is fully unfolded, if the visibility in the room decreases due to various reasons (such as power outages, large amounts of smoke generated by fire), it is difficult for personnel to observe the location of the evacuation passage. At this time, the guide plate 28 can be rotated to make the guide plate 28 horizontal, and then the side plate 29 is rotated to unfold the elastic evacuation indicator cloth 30 between the two side plates 29 to indicate the evacuation direction for personnel, making it easier for personnel to quickly find the evacuation exit. In addition, the guide plate 28 can also play a role in diverting the evacuated personnel, allowing the evacuated personnel to pass more smoothly from both sides of the column 4, making it difficult for the evacuated personnel to come into contact and collide with the column 4.

[0046] As a preferred technical solution of the present invention, a rotating groove 32 is provided in the middle position of the column 4, and a rotating ring 33 is rotatably connected inside the rotating groove 32. A notch matching the guide plate 28 is provided on one side of the rotating ring 33, and a plurality of equally spaced toggle grooves 34 are provided on the rotating ring 33.

[0047] Specifically, under normal circumstances (i.e., when no emergency occurs), the guide plate 28 is in the storage groove 27. At this time, the rotating ring 33 can be turned to make the notch of the rotating ring 33 staggered with the guide plate 28 to prevent the guide plate 28 from rotating and opening by itself. At the same time, a turning groove 34 is provided to make it more convenient for the rotating ring 33 to be turned.

[0048] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
