Technical Field

[0001] The utility model belongs to the technical field of one-way access doors, and particularly relates to a transmission structure of a secondary door body for a one-way access door. Background Art

[0002] With the acceleration of the urbanization process, the demand for the safety and management of public places and buildings is increasing day by day. As an effective personnel flow control device, one-way access doors have been widely used in places such as subway stations, airports, shopping malls, and office buildings. Such door systems usually need to have high-efficiency passage capabilities, safety performance, and good user experience. Among them, the secondary door body, as a supplement to the main door body, often plays roles such as assisting in controlling the flow direction of people and enhancing safety protection.

[0003] In the design of traditional one-way access doors, the transmission structure of the secondary door body mostly adopts the method of torsion spring drive or motor drive combined with a complex gear set. The torsion spring structure uses the elastic potential energy of the spring to realize the automatic opening and closing of the door body, which has the advantages of simple structure and low cost. However, there are problems such as limited service life, unstable door body opening and closing speed, and difficult to accurately control the force after spring fatigue. After long-term use, it is easy to generate large vibrations and noises, affecting the use experience and the tranquility of the surrounding environment.

[0004] Therefore, based on some of the above situations in the prior art, this application has been further designed and improved. Content of the Utility Model

[0028] Refer to Figures 1 to 8, An improved one-way access door, including a frame 100, the frame 100 is in the shape of 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-back direction in the rotation area 110, the secondary door area 120 is located on one side of the entrance, and 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, and 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 that cooperates with the one-way ratchet 211 is assembled on the frame 100. The design of the one-way ratchet 211 and the electromagnetic lock 130 enables 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.

[0029] The one-way access door described in this application further includes a driving mechanism, and the driving mechanism includes a driving unit 400 and a transmission shaft 410. The driving unit 400 has an output shaft 401, a first pulley 402 is arranged on the output shaft 401, a second pulley 411 is arranged 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 wheel 212 is arranged on the door shaft 210, and a second transmission wheel 412 that is meshed and assembled with the first transmission wheel 212 is arranged on the transmission shaft 410. The design of pulley transmission 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.

[0030] 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 secondary door body 300, and a slideway 170 for the sliding seat 520 to slide is arranged on the frame 100. The eccentric plate 500 is fixedly assembled with the second pulley 411. The linkage mechanism can drive the secondary door body 300 to reciprocate through the rotation of the revolving door body 200.

[0031] The auxiliary door body 300 includes a reel 310, a rolling curtain 320 is wound on the reel 310, 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 auxiliary door. A third pulley 311 is assembled on the reel 310, a fourth pulley 140 is assembled on the frame 100, and 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 reel 310 provided with a torsion spring structure, this design has less requirement for the strength of the structure, can more effectively reduce the vibration and noise during the transmission process, ensure smooth operation, and improve the stability and reliability of the overall system.

[0032] In addition, the door head 330 is of a V-shaped structure, and the tip of the V-shaped structure has a smooth transition. 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. A plurality of connecting rods 331 are arranged at the top of the V-shaped structure of the door head 330, 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.

[0033] 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.

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 events such as fragments stabbing and penetrating and falling, 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.

[0036] 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 embodiments, 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 storage space for the secondary door. The combination of the two presents a unique and harmonious visual effect.
