[0026] Refer to Figures 1 to 8 , An improved one-way access door, including a frame 100, the frame 100 is a quadrangular prism, a rotation area 110 and a secondary door area 120 are arranged inside the frame 100, a revolving door body 200 is assembled in the rotation area 110, an entrance and an exit are respectively arranged in the front-rear direction of the rotation area 110, the secondary door area 120 is located on one side of the entrance, a secondary door body 300 is assembled in the secondary door area 120, the revolving door body 200 has a door shaft 210 as the rotation center, the door shaft 210 drives the secondary door body 300 to reciprocate in the radial direction of the revolving door body 200 through a linkage mechanism, a one-way ratchet 211 is assembled on the door shaft 210, and an electromagnetic lock 130 cooperating with the one-way ratchet 211 is assembled on the frame 100. The designs of the one-way ratchet 211 and the electromagnetic lock 130 enable the one-way access door to have a one-way locking function. When locking is required, the electromagnetic lock 130 will accurately engage with the ratchet, effectively preventing unauthorized reverse rotation of the door even if there is an external force attempting to move the door body in the reverse direction.

[0027] The one-way access door described in this application further includes a driving mechanism, which includes a driving unit 400 and a transmission shaft 410. The driving unit 400 has an output shaft 401, on which a first pulley 402 is provided. A second pulley 411 is provided on the transmission shaft 410, and the first pulley 402 and the second pulley 411 are connected and driven by a first synchronous belt 403. A first transmission pulley 212 is provided on the door shaft 210, and a second transmission pulley 412 meshingly assembled with the first transmission pulley 212 is provided on the transmission shaft 410. The design of pulley drive ensures the synchronism and stability of power transmission, reduces energy loss and vibration during the transmission process, and improves the smoothness and efficiency of operation. An electromagnetic clutch 420 is assembled on the output shaft 401. Such a structural design enables the system to respond quickly as needed, achieving smooth power transmission and timely separation.

[0028] In this application, the linkage mechanism includes an eccentric plate 500, a connecting rod 510, and a sliding seat 520. The eccentric plate 500 is connected to the connecting rod 510, the connecting rod 510 is connected to the sliding seat 520, the sliding seat 520 is connected to the sub-door body 300, and a slideway 170 for the sliding seat 520 to slide is provided on the frame 100. The eccentric plate 500 is fixedly assembled with the second pulley 411. The linkage mechanism can drive the sub-door body 300 to move reciprocally by the rotation of the rotating door body 200.

[0029] The sub-door body 300 includes a reel 310, on which a rolling curtain 320 is wound. A door head 330 is assembled at the free end of the rolling curtain 320, and the door head 330 is connected to the sliding seat 520. The sliding of the sliding seat 520 can drive the winding of the rolling curtain 320 to realize the function of the sub-door. A third pulley 311 is assembled on the reel 310, and a fourth pulley 140 is assembled on the frame 100. The third pulley 311 and the fourth pulley 140 are connected and driven by a second synchronous belt 340. A belt clip 521 is assembled on the sliding seat 520, and the belt clip 521 is fixedly connected to the second synchronous belt 340. Compared with the design of the reel 310 provided with a torsion spring structure, this design has a lower requirement for the strength of the structure, can more effectively reduce vibration and noise during the transmission process, ensure smooth operation, and improve the stability and reliability of the overall system.

[0030] In addition, the door head 330 is of a V-shaped structure, and the tip of the V-shaped structure is smoothly transitioned. The V-shaped structure can guide the movement of the curtain more smoothly, and the smooth transition treatment reduces the risk of collision and increases the safety of use. The door head 330 is provided with a plurality of connecting rods 331 at the top of the V-shaped structure, and the plurality of connecting rods 331 are fixedly assembled with the sliding seat 520. This design enhances the connection stability between the door head 330 and the sliding seat 520. The rolling curtain 320 includes a plurality of curtain sheets hinged in sequence. The design of the hinged curtain sheets enables the rolling curtain 320 to flexibly bend when unfolding and rolling up, adapt to various opening and closing angles, and at the same time maintain good flatness, further optimizing the sealing performance and appearance of the door body.

[0031] Furthermore, the present application further includes an anti-pinch mechanism, the anti-pinch mechanism includes a first anti-pinch member and a second anti-pinch member, and the first anti-pinch member and the second anti-pinch member are assembled on the side walls at the entrance and exit of the rotation area. The first anti-pinch member includes an anti-pinch frame 150, and an anti-pinch door 151 is slidably assembled in the anti-pinch frame 150. The second anti-pinch member includes an anti-pinch decorative plate 152. The anti-pinch mechanism can reduce the possibility of pedestrians putting their hands into the gap between the rotating door body 200 and the inner wall of the rotation area 110.

[0032] In order to further strengthen the safety performance, intelligent sensing devices such as infrared sensors or radar detectors can be integrated in the rotation area 110 for real-time monitoring of the passing state and automatic control of the opening and closing of the secondary door, so as to greatly improve the user experience and safety while ensuring the one-way passing efficiency. The one-way passing door of the present application is also equipped with an emergency stop button and a status indicator light system. The emergency stop button is arranged at a conspicuous and easily accessible position on the door body. In case of an emergency, the user can immediately operate it to stop the movement of the door body, effectively preventing accidental injuries. The status indicator light displays the current working mode of the door body (such as running, standby, fault, etc.) through lights of different colors, facilitating maintenance personnel to timely grasp the equipment status and conduct corresponding inspections and repairs. Specifically, for example, a light curtain induction plate 180 is assembled in the rotation area 110 corresponding to the secondary door body 300. When the light curtain induction plate 180 senses that there is a foreign object entering the area of the secondary door body 300, the one-way passing door will stop running and alarm.

[0033] In terms of material selection, transparent decorative panels 160 are assembled on the four sides of the frame 100 and the side walls of the rotating area 110, allowing external light to pass through the transparent decorative panels 160, ensuring sufficient light in the rotating area 110 and making pedestrians entering the rotating area 110 feel comfortable. The revolving door body 200 includes a number of door panels 220 arranged around the door shaft 210. The door panels 220 include door frames 221 made of profiles, and glass plates 222 are assembled inside the door frames 221. This makes the inside of the revolving door bright and well-lit, avoiding the uncomfortable feeling of darkness and narrowness. The glass plate 222 is laminated glass. Even if the glass breaks, the fragments will be adhered to the film, and the surface of the broken glass remains clean and smooth. This effectively prevents the occurrence of incidents where fragments pierce and penetrate and fall, ensuring personal safety. The frame 100, the door body, and each transmission component of the present invention are all made of high-quality corrosion-resistant materials, such as stainless steel or aluminum alloy, and are processed through precision machining to ensure the structural strength and durability under long-term use. In particular, for the door panels 220 of the revolving door body 200, their surface treatment not only considers aesthetics but also incorporates anti-fingerprint and easy-to-clean designs, effectively reducing the need for daily maintenance.

[0034] As another embodiment of this application, the frame 100 has a combined shape of a cylinder and a prism. The rotating area 110 is located inside the cylinder, and the secondary door area 120 is located inside the prism. Compared with the above embodiment, the shape of this embodiment is more concise. The cylindrical rotating area 110 ensures the smoothness and continuity of passage, while the prismatic secondary door area 120 provides a stable installation foundation and a more concealed secondary door storage space. The combination of the two presents a unique and harmonious visual effect.
