Description

Technical Field

[0001] The utility model belongs to the field of one-way revolving doors, in particular to a one-way revolving door. Background Art

[0002] In public buildings, commercial centers, large office spaces and other crowded areas, revolving doors are usually used as entrances and exits to effectively manage and control the flow of people. Revolving doors can not only isolate the outside environment, maintain indoor temperature and cleanliness, but also play a role in security to a certain extent. Traditional revolving doors are mostly designed for two-way passage, that is, allowing people to enter and exit freely in both directions. However, in certain specific occasions, such as stations, revolving doors also need to have a one-way passage function to prevent passengers from passing items without security inspection.

[0003] In order to achieve the function of one-way passage, in the existing technical solutions, the Chinese utility model patent with application number 202020076605.X discloses a sub-door group and a one-way door with the sub-door group. The one-way door includes a main door that performs rotational motion and a sub-door group that performs linear reciprocating motion. The sub-door group includes sub-door 1, sub-door 2, and sub-door 3. These sub-doors and the sub-door group and the main door are connected by a complex linkage mechanism to achieve the effect of one-way passage.

[0004] Although this design can achieve the purpose of one-way traffic, it has the following disadvantages:

[0005] 1. Complex structure: Since multiple auxiliary doors and complex linkage mechanisms are required to achieve one-way passage, the structure of the entire door becomes complex, which not only increases the difficulty of design and manufacturing, but also makes maintenance and repair work more difficult. The complex structure means that more materials and higher processing precision are required, which will undoubtedly increase the production cost of the entire revolving door.

[0006] 2. High failure rate: The existence of multiple auxiliary doors and linkage mechanisms increases the possibility of failure of the revolving door. Once a part fails, it may affect the normal operation of the entire door, resulting in reduced traffic efficiency or even unusable.

[0007] In view of the above-mentioned deficiencies of the prior art, it is necessary to develop a new type of one-way revolving door, aiming to simplify the structure, reduce the cost, and reduce the failure rate, so as to improve the reliability and economy of the revolving door.

[0031] refer to Figures 1 to 5 A one-way revolving door includes a door frame 10, the left and right sides of the door frame 10 are closed, and the front and rear sides of the door frame 10 are respectively provided with an entrance 11 and an exit 12. The door frame 10 is equipped with a revolving door body 20 and a one-way door body 30. The space area in the door frame 10 is divided into a passing area and a reverse area by the entrance 11, the center of the revolving door body 20, and the exit 12 as the dividing line. The one-way door body 30 is located on the side of the reverse area. The revolving door body 20 and the one-way door body 30 are connected by a linkage mechanism 40. The revolving door body 20 includes a rotating shaft 21, and a plurality of door panels 22 are distributed in an annular manner on the rotating shaft 21. The one-way door body 30 includes a rolling door shaft 31, and a rolling curtain 32 is installed on the rolling door shaft 31. The linkage mechanism 40 is connected to the head end of the rolling curtain 32 for pulling.

[0032] In the present invention, the rotation of the revolving door body 20 can be driven by a motor for unidirectional rotation, or can be driven by pedestrians' hand push. When driven by pedestrians' hand push, a unidirectional rotation structure can be added to the revolving door body 20 to prevent pedestrians from pushing in the opposite direction. A reset structure such as a torsion spring shaft that can reset itself can be added to the rolling door shaft 31 to prevent the rolling curtain 32 from getting stuck when rolling back or unfolding.

[0033] Preferably, the linkage mechanism 40 includes a first gear 41 and a second gear 42 meshing with each other, the first gear 41 is assembled with the rotating shaft 21, the second gear 42 is coaxially assembled with a connecting rod seat 43, a first connecting rod 44 is assembled on the connecting rod seat 43, one end of the first connecting rod 44 is connected to the connecting rod seat 43, the other end of the first connecting rod 44 is connected to the second connecting rod 45, one end of the second connecting rod 45 is connected to the first connecting rod 44, and the other end of the second connecting rod 45 is connected to the sliding seat 46. The door frame 10 is provided with a limiting slide 47 for the sliding seat 46 to slide between the rolling door shaft 31 and the rotating shaft 21 of the rotating door body 20. Under this structural design, when the rotating door body 20 rotates, the first gear 41 drives the second gear 42 to rotate, and the first connecting rod 44 fixedly assembled with the second gear 42 drives the sliding seat 46 to move linearly in the limiting slide 47, so that the rotation of the rotating door body 20 can be converted into a reciprocating linear movement of the sliding seat 46 in the limiting slide 47.

[0034] The working principle of the one-way revolving door described in the utility model is as follows: Figure 4 and Figure 5 , the rotating door body 20 rotates and drives the rolling curtain 32 to move linearly back and forth. When the door panel 22 of the rotating door body 20 rotates to the area where the rolling curtain 32 is located, the rolling curtain 32 is rolled back to the rolling door shaft 31. At this time, the one-way door body 30 is in a fully open state to facilitate the passage of the door panel 22. After the door panel 22 passes, the rolling curtain 32 is gradually unfolded under the drive of the linkage mechanism 40. After the head end of the rolling curtain 32 approaches or reaches the rotating shaft 21 of the rotating door body 20, it is gradually rolled back until the next door panel 22 rotates to the area where the rolling curtain 32 is located. The continuous movement process of the rolling curtain 32 gradually unfolding and then gradually rolling back occurs in the area between two adjacent door panels 22 in the retrograde area, so that the space in this area is always restricted or separated by the rolling curtain 32, and cannot accommodate pedestrians or objects.

[0035] To ensure smooth movement of the rolling curtain 32, the head end of the rolling curtain 32 for pulling is equipped with a door head plate 33, and the door head plate 33 is connected to the slide seat 46, so that the rotation of the revolving door body 20 can drive the rolling curtain 32 to move linearly. The door head plate 33 covers the head end of the rolling curtain 32 for pulling in the vertical direction to ensure that the upper and lower sides of the head end of the rolling curtain 32 can move synchronously.

[0036] Furthermore, the door frame 10 is equipped with interior panels 13 on the left and right sides, and the interior panels 13 are arc-shaped, so that the interior panels 13 and the door panels 22 can cooperate to isolate the entrance 11 and the exit 12, avoiding leaving a gap for convenient delivery of items.

[0037] Furthermore, in order to enhance the aesthetics of the revolving door, the door frame 10 is equipped with a top decorative panel 14 above the revolving door body 20 and the one-way door body 30, and the linkage mechanism 40 is located above the top decorative panel 14 to hide the linkage mechanism 40, so that the interior of the revolving door looks simple and beautiful. The door panel 22 includes a door frame 23, and a glass plate 24 is installed in the door frame 23, so that the interior of the revolving door is bright and well-lit, avoiding the discomfort of darkness and narrowness. The door frame 23 is made of aluminum profiles to reduce the weight of the door panel 22, and the glass plate 24 is laminated glass. Even if the glass is broken, the fragments will be adhered to the film, and the broken glass surface will remain clean and smooth. It effectively prevents the occurrence of fragments stabbing and penetrating falling events to ensure personal safety.

[0038] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
