[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Please refer to Figure 1-4 , Figure 1 A structural schematic diagram of an embodiment of a two-wing revolving door structure provided by the utility model; Figure 2 A schematic structural diagram of a positioning spring clamping bead of an embodiment of a two-wing revolving door structure provided by the utility model; Figure 3 A schematic diagram of the structure of the positioning spring clamping beads of an embodiment of the two-wing revolving door structure provided by the utility model; Figure 4 The utility model provides a two-wing revolving door structure of an embodiment of the positioning spring card assembly installation structure schematic diagram.

[0033] In a specific embodiment, the two-wing revolving door structure includes:

[0034] The rebound door 1 is connected to the rotating fixed door 2 via a rotating shaft 3;

[0035] The rotating fixed door 2 is fixedly connected to the rotating main beam 7 at the top and rotates with the rotating main beam 7;

[0036] The rotating support beam 4 is fixedly connected to the rotating main beam 7 at the top and rotates with the rotating main beam 7;

[0037] An elastic component 5, wherein a first end of the elastic component 5 is connected to the rebound door 1, and a second end of the elastic component 5 is connected to the rotationally fixed door 2;

[0038] Among them, the rebound door 1 folds inward after encountering an obstacle, and the state of the elastic component 5 changes. After the revolving door sensor senses that there is no obstacle, the external force driving the rebound door 1 to fold disappears, and the rebound door 1 is driven by the external force of the elastic component 5 to return to the normal operating position.

[0039] By setting an elastic component 5, and connecting the first end of the elastic component 5 to the rebound door 1, and the second end to the rotating fixed door 2, the rebound door 1 folds inwards after encountering an obstacle, and the state of the elastic component 5 changes. After the rotating door sensor senses that there is no obstacle, the external force driving the rebound door 1 to fold disappears, and the rebound door 1 is driven by the external force of the elastic component 5 to return to the normal operating position. After the rebound door 1 folds inwards after encountering an obstacle, it can automatically return to the normal operating position. The structure is simple, and no manual return is required, thereby improving the traffic efficiency.

[0040] The type and size of the elastic component 5 are not limited in the present application. The elastic component 5 is a spring elastic component, a rubber elastic component, a cylinder elastic component or an electromagnet elastic component, or other elastic components 5. In one embodiment, the elastic component 5 is an electromagnet elastic component, and the first magnetic pole of the electromagnet elastic component is installed on the rebound door 1, and the second magnetic pole is installed on the rotating fixed door 2. When the rebound door 1 folds inward after encountering an obstacle, the electromagnet elastic component controls the first magnetic pole and the second magnetic pole to be the same, so that the first magnetic pole and the second magnetic pole repel each other, and after the rotating door sensor senses that there is no obstacle, the first magnetic pole and the second magnetic pole are controlled to be different in magnetic pole, so that the first magnetic pole and the second magnetic pole attract each other, driving the rebound door 1 to return to the normal operating position.

[0041] By changing the polarity of the two magnetic poles under different conditions, it is achieved that during the folding process of the rebound door 1, magnetism is generated without electricity, or repulsion is generated, thereby ensuring efficient folding of the rebound door 1. During the rebound process, the recovery of the rebound door 1 is accelerated through suction, thereby improving the recovery efficiency.

[0042] It should be pointed out that, in the present application, only one type of the elastic component 5 mentioned above may be used, or multiple types may be used to ensure its reliability in use.

[0043] In order to further improve the convenience of connection, in one embodiment, the two-wing revolving door structure also includes a connecting plate 6 arranged between the rebound door 1 and the elastic component 5, the rebound door 1 is connected to the elastic component 5 through the connecting plate 6, and the connecting plate 6 is rotationally connected to the rebound door 1 and the elastic component 5.

[0044] The elastic component 5 and the rebound door 1 can be freely connected through the connecting plate 6, and the relevant parameters such as the length can be freely designed, which reduces the design difficulty.

[0045] The present application does not limit the material, size, connection and fixing method of the connecting plate 6 .

[0046] In order to reduce or even avoid misoperation when the rebound door 1 is in a folded state, in one embodiment, the two-wing revolving door structure also includes a limiter arranged on the connecting plate 6, which is used to limit the elastic component 5 during the process from the rebound door 1 being folded to the rebound door 1 canceling the folding after the revolving door sensor senses that there is no obstacle, control the elastic component 5 to stop exerting force on the rebound door 1, and control the elastic component 5 to drive the rebound door 1 to return to the normal operating position during the process from the rebound door 1 canceling the folding after the revolving door sensor senses that there is no obstacle.

[0047] By setting a limiter, the elastic component 5 is limited to eliminate the thrust or pulling force when the rebound door 1 is in the folded state. On the one hand, it reduces the damage to the rebound door 1. On the other hand, it can also avoid controlling the release of the thrust on the rebound door 1 during the process of canceling the folding, avoid dangerous operations caused by excessive acceleration, etc., and improve the safety of use.

[0048] In order to further meet different connection requirements, in one embodiment, the two-wing revolving door structure also includes a plurality of connecting holes arranged on the connecting plate 6 and along the length direction of the connecting plate 6, the elastic component 5 is connected to the connecting element of the connecting plate 6 through the connecting holes, and the plurality of connecting holes are arranged at equal intervals on the connecting plate 6.

[0049] By setting up multiple connection holes, different connection holes are connected in different situations to adapt to different occasions. For example, if the rebound door 1 needs to rebound quickly, the connection hole close to the rebound door 1 should be used, otherwise, the connection hole far away from the rebound door 1 should be used. The present application does not limit the shape, size and spacing of the connection holes.

[0050] In addition to the above-mentioned adjustment method, since it can only adopt discrete adjustment and cannot be continuously adjusted, in one embodiment, the two-wing revolving door structure also includes a slide rail arranged on the connecting plate 6 along the length direction of the connecting plate 6, and the connecting element between the elastic component 5 and the connecting plate 6 is slidably connected to the connecting plate 6 through the slide rail, and the relative position of the slide rail and the connecting element is fixed by a clamping component.

[0051] By setting the slide rail, continuous position adjustment can be achieved to meet different needs. Multiple elastic components 5 can also be set at the same time for connection to meet different design requirements.

[0052] This application does not limit the configuration, shape, size, etc. of the slide rail.

[0053] In order to fully ensure the efficient resetting of the rebound door 1, in one embodiment, the two-wing revolving door structure also includes a damping component and a charging component arranged in parallel or in series with the elastic component 5, the damping component is used to eliminate the vibration of the elastic component 5 after the elastic component 5 is folded or returned to the normal operating position, and the charging component is used to charge the elastic component 5 after it reaches the new position, so that the elastic component 5 has the ability to drive the rebound door 1 to return to the normal operating position.

[0054] The vibration generated by the elastic component 5 after the rebound door 1 is folded or returned to the normal operating position is eliminated by the damping component, thereby improving the reliability and service life of the rebound door 1. The charging component can eliminate the energy reduced by the vibration of the elastic component 5 for the damping component, and charge the elastic component 5 after reaching the new position, so that the elastic component 5 can drive the rebound door 1 to return to the normal operating position, thereby improving the use efficiency of the rebound door 1.

[0055] Because the front part of the rebound door 1 is prone to swing inward when it is affected by strong wind on the vertical side, and long-term swinging affects its service life. In order to solve this technical problem, ensure the reliability and safety of use and improve the service life, in one embodiment, the two-wing revolving door structure also includes a positioning spring bead 10 arranged between the top rotating bracket and at least one of the rebound door 1, the rotating support beam 4, and the rotating main beam 7. The positioning spring bead 10 includes a shell 103, a spring 102 arranged on the shell 103, and a steel ball 101 arranged on the top of the spring 102. The positioning spring bead 10 is used to press the steel ball back into the cavity of the shell 103 where the spring 102 is installed after the external force borne by the rebound door 1 exceeds the rebound force of the positioning spring bead 10, and the rebound door 1 performs a folding operation.

[0056] By providing a positioning spring bead 10, when the rebound door 1 is subjected to an external force exceeding the rebound force of the positioning spring bead 10, the steel ball is pressed back into the cavity of the shell 103 in which the spring 102 is installed, and the rebound door 1 is folded to avoid slight shaking caused by external strong winds or external small thrusts, thereby improving the safety, reliability and service life of use.

[0057] In addition to the above-mentioned structure, other structures may also be used, such as setting a first magnet on the top of the rebound door 1 or the rotating support beam 4, and setting a second magnet on the path passed by the first magnet during the rotation of the rebound door 1, so that in the absence of sufficient external force, the rebound door 1 will not rotate and the shaking will be reduced. A damping component may also be provided to eliminate shaking, etc., thereby improving the reliability of use.

[0058] The present application includes but is not limited to the above-mentioned positioning spring bead 10 structure, and other structures may also be used. The present application does not limit the size and shape of the positioning spring bead 10.

[0059] In order to further reduce the damage caused to the revolving door and avoid the damage caused by the rolling process of the steel ball 101, in one embodiment, the two-wing revolving door structure also includes a bead seat 9 arranged on the top rotating bracket and an arc track connected to the bead seat 9 and located on both sides of the bead seat 9, and the surface of the bead seat 9 is provided with a groove. When the rebound door 1 does not undergo a folding operation, the steel ball 101 of the positioning spring bead 10 is confined in the groove. After the external force borne by the rebound door 1 exceeds the rebound force of the positioning spring bead 10, the steel ball slides out of the groove and moves on the arc track.

[0060] By providing the bead holder 9 and the groove and adjusting the size of the groove, the limitation on driving by different external forces is achieved, thereby improving the flexibility of use.

[0061] The present application does not limit the shape and size of the bead holder 9 and the groove.

[0062] In order to further improve the installation efficiency and convenience of the bead holder 9, in one embodiment, the two-wing revolving door structure further includes a rotating mounting seat 8 for mounting the bead holder 9, and the rotating mounting seat 8 is fixed to the top rotating bracket.

[0063] It should be pointed out that in addition to the above-mentioned installation method, in the present application, the bead seat 9 and the rotating mounting seat 8 can also be installed on the top of the rebound door 1, the rotating support beam 4, and the rotating main beam 7, and the positioning spring 102 bead 10 can be installed on the rotating bracket, or other installation methods can be used.

[0064] The present application does not limit the installation of the bead holder 9, which can be circumferentially continuous, that is, the steel ball 101 will automatically enter the next groove after coming out of a groove. However, this structure will make the revolving door have a strong sense of frustration, consume more external force during rotation, and have high energy consumption. It is also possible to set a groove at a certain angle. For example, if there are three doors, three grooves are set at designated positions, and the revolving door will be restricted to stop rotating only at specific positions.

[0065] In one embodiment, the two-wing revolving door structure includes: a rebound door 1, which is connected to a rotating fixed door 2 via a rotating shaft 3; the rotating fixed door 2 is fixed to a top rotating main beam 7 and rotates with the rotating main beam 7; the rotating shaft 3 connects the rebound door 1 and the rotating fixed door 2; a rotating support beam 4, on which one end of a spring connecting device is fixed; a connecting plate 6, one end of which is fixed to the upper part of the rebound door 1 and the other end is connected to a spring, and both ends of the fixed position can rotate.

[0066] When the rebound door 1 encounters an obstacle, it will fold inward. In the early stage of the folding of the rebound door 1, the spring of the spring connecting device will not be stretched. After folding to a certain position, the spring begins to be stretched. When the rebound door 1 rebounds to the set position, it will remain motionless. After a period of time, the revolving door sensor senses that there is no obstacle, and the force that causes the rebound door 1 to fold will disappear. At this time, the rebound door 1 only bears the spring tension. Under the action of the spring tension, the rebound door 1 will return to the normal operating position.

[0067] When the revolving door is in normal use, the steel ball 101 of the positioning spring card bead 10 is pressed against the hemispherical groove on the inner side of the card bead seat 9. When the rebound door 1 receives wind force, the rebound door tends to fold. This is because the card bead seat 9 squeezes the steel ball 101, and the steel ball 101 squeezes the lower spring 102. The spring 102 generates elastic force. Only when the wind force exceeds a certain limit, the steel ball 101 is completely pressed into the inner cavity of the shell 103, and the rebound door 1 will swing. By selecting springs 102 of different specifications, it can be ensured that the folding of the rebound door 1 is not affected when it touches an obstacle, and it can also prevent the rebound door 1 from swinging under the action of wind, affecting safety and user experience.

[0068] In this solution, the spring 102 can be replaced by a door closer; the positioning spring card bead 10 can be replaced by a strong magnet.

[0069] To summarize, the two-wing revolving door structure provided by the embodiment of the utility model is provided with an elastic component, and the first end of the elastic component is connected to the rebound door, and the second end is connected to the rotating fixed door. The rebound door folds inwards after encountering an obstacle, and the state of the elastic component changes. After the revolving door sensor senses that there is no obstacle, the external force driving the rebound door to fold disappears, and the rebound door is driven by the external force of the elastic component to return to the normal operating position. After the rebound door folds inwards after encountering an obstacle, it can automatically return to the normal operating position. The structure is simple, and no manual return is required, thereby improving the traffic efficiency.

[0070] The above is a detailed introduction to the two-wing revolving door structure provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
