[0026] 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.
[0027] Please refer to Figure 1-2 , Figure 1 A schematic structural diagram of a normal operating state of an embodiment of the folding structure of a revolving door without a display box provided by the utility model; Figure 2 The present invention is a schematic diagram of a folded state structure of an embodiment of the folding structure of a display box-free revolving door provided by the present invention.
[0028] In a specific implementation, the folding structure of the display case-free revolving door includes:
[0029] A plurality of fixed walls 1, with gaps being provided between adjacent fixed walls 1;
[0030] A central fixed column, arranged at the center of the area enclosed by the plurality of fixed walls 1;
[0031] An extension arm, the inner end of which is connected to the central fixing column;
[0032] A first rotating fixed door 2 and a second rotating fixed door 4 are arranged on different sides of the extension arm;
[0033] The first rotating folding door 5 is arranged on the side of at least one of the first rotating fixed door 2 and the second rotating fixed door 4 away from the extension arm, and an obstacle sensor is arranged on the side away from the extension arm, which is used to open or cover the gap during rotation together with the first rotating fixed door 2 or the second rotating fixed door 4 in a normal state, and drive the first rotating folding door 5 to fold toward the central fixed column after the obstacle sensor senses an obstacle.
[0034] The folding structure of the revolving door without a display box can realize the folding function in a small space when encountering an obstacle. When the obstacle sensor senses an obstacle, the first revolving folding door 5 arranged on the side of the first revolving fixed door 2 and the second revolving fixed door 4 away from the extension arm is driven to fold toward the central fixed column, and the revolving door is emergency braked instead of folding outward. The available braking distance is increased, and the outermost side of the movable door does not exceed the original position range after being folded, thereby increasing the braking distance and efficiency.
[0035] In order to further improve the braking efficiency and increase the braking distance, in one embodiment, the folding structure of the display box-free revolving door also includes a second revolving folding door 6 arranged on the side of the first revolving folding door 5 facing away from the first revolving folding door 5, and a second obstacle sensor is arranged on the front side of the second revolving folding door 6 facing away from the first revolving folding door 5, for driving the second revolving folding door 6 to fold toward the first revolving folding door 5 after sensing an obstacle.
[0036] By arranging a second revolving folding door 6 and a second obstacle sensor on the side of the first revolving folding door 5 away from the first revolving folding door 5, the second revolving folding door 6 is driven to fold toward the first revolving folding door 5 after encountering an obstacle, and a second folding is achieved with the first revolving folding door 5, thereby increasing the braking distance again. In this way, the space swept by the folding door during the folding process can be reduced while the braking distance remains unchanged, so that even if someone passes through the revolving door, the impact on the passing person can be reduced, thereby improving the safety of the revolving door.
[0037] The present application does not limit the lengths of the second rotary folding door 6 and the first rotary folding door 5 . In order to ensure the reliability of folding, the length of the second rotary folding door 6 is generally less than or equal to the length of the first rotary folding door 5 .
[0038] In the present application, there is no limitation on the size, folding method and material of the first rotating fixed door 2 and the second rotating fixed door 4. The first rotating fixed door 2 and the second rotating fixed door 4 are aluminum alloy fixed doors or stainless steel fixed doors. The first rotating fixed door 2 is located at the front end of the second rotating fixed door 4 in the rotation direction, and the length of the first rotating fixed door 2 is less than or equal to the length of the second rotating fixed door 4.
[0039] In the present application, the first rotating fixed door 2 and the second rotating fixed door 4 are fixed to the movable door. The front end of the movable door can be set. According to the needs of rotation, folding doors can be set on the first rotating fixed door 2 and the second rotating fixed door 4 to achieve folding when encountering obstacles during different rotation directions.
[0040] If the folding door can only rotate in one direction during operation, a folding door can be installed only at the front end of the movable door. If the folding door at the front end fails and cannot rotate, the folding door at the rear end can be rotated in the opposite direction to fold open a gap, thereby maintaining the revolving door. The folding door can even be folded directly to obtain a gap for the staff to enter, thereby maintaining the revolving door.
[0041] In order to ensure the normal operation of the revolving door in the present application, the length of the first revolving folding door 5 is greater than or equal to 50%-60% of the length of the second revolving fixed door 4, and the sum of the lengths of the first revolving fixed door 2, the first revolving folding door 5, and the second revolving folding door 6 is greater than or equal to the length of the gap.
[0042] The present application does not limit the connection and fixing method of the rotary folding door. The first rotary fixed door 2, the second rotary fixed door 4 and the first rotary folding door 5, and the first rotary folding door 5 and the second rotary folding door 6 are connected by a folding axis or hinge, or are connected in other ways.
[0043] In order to further improve the maintenance efficiency of the revolving door in the present application, in one embodiment, the extension arm includes a smooth door 7 and a partition door 3, the inner end of the smooth door 7 is connected to the central fixed column, and the outer end is connected to the partition door 3, the smooth door 7 is a smooth door 7 that can slide toward the notch, and the outer end of the partition door 3 is connected to the first rotating fixed door 2 and the second rotating fixed door 4.
[0044] By setting the smooth door 7 and sliding it toward the partition doors 3 on both sides, the staff can shuttle between different spaces, so that when the revolving door does not rotate, maintenance can be carried out on various positions of the revolving door, thereby improving the maintenance efficiency of the revolving door.
[0045] The present application does not limit the size and sliding mode of the sliding door 7 and the partition door 3 .
[0046] In order to further protect the partition door 3, in one embodiment, the folding structure of the display box-free revolving door also includes a limiter arranged on the folding axis or the hinge, which is used to limit the rotation angle of the first revolving folding door 5 and the second revolving folding door 6, and prohibit the first revolving folding door 5 and the second revolving folding door 6 from touching the partition door 3 during the folding process.
[0047] By setting a limiter to limit the rotation angle of the first rotating folding door 5 and the second rotating folding door 6, the first rotating folding door 5 and the second rotating folding door 6 are prohibited from touching the partition door 3 during the folding process, thereby avoiding the loss caused by collision with the partition door 3 during the folding process.
[0048] In one embodiment, the folding structure of the display box-free revolving door includes: a fixed wall 1; a first revolving fixed door 2; a partition door 3; a second revolving fixed door 4, which is smaller in size than the first revolving fixed door and is made of aluminum profiles to facilitate folding around hinges and prevent the partition door 3 from being touched during folding around the hinges; a first revolving folding door 5, which is connected to the second revolving fixed door 4 through a hinge and can only be folded inward; a second revolving folding door 6, which is connected to the first revolving folding door 5 through a hinge, has an obstacle sensor installed at the front end, and the overall length generally does not exceed the first revolving folding door 5, and can only be folded outward; a smooth door 7, which can be opened by sliding to both sides (in the direction of the partition door 3).
[0049] The revolving door generally rotates in only one direction, so only the front end of the revolving door is designed to be a foldable structure. The second fixed door is a fixed door that does not rotate, and one side of the door is hinged to connect with the first revolving folding door 5. The first revolving folding door 5 and the second revolving folding door 6 are foldable components. The folding door is best with two pieces, and can also be multiple pieces. When there are multiple pieces, the width of the second fixed door does not need to be changed; if there is only one piece, in order to ensure that the damage to obstacles is reduced, the width, length and other dimensions of the second fixed door need to be redesigned.
[0050] In addition to the above-mentioned folding, the first rotary folding door 5, the second rotary folding door 6, and even the second fixed door can also slide successively to the inside or outside of the rotary fixed door, which is achieved by the motor drive at the connection.
[0051] During the normal operation of the revolving door, after the obstacle sensor senses that the revolving door touches an obstacle, the revolving door performs emergency braking, and the folding doors fold at the same time, with the first revolving folding door 5 folding inward and the second revolving folding door 6 folding outward. After sensing that the obstacle has left, the folding door returns to its original position after a few seconds, and the revolving door continues to operate normally.
[0052] The folding door will not touch the partition door 3 when folding, and the outermost side of the folding door will not exceed the original position range after folding. After the change, the braking distance can be increased, the motor can be braked relatively smoothly, the service life is increased, and the loss is reduced.
[0053] To summarize, the folding structure of the display box-free revolving door provided in the embodiment of the utility model can realize the folding function in a small space when encountering an obstacle, and the movable door is folded and the revolving door is urgently braked when encountering an obstacle, and the available braking distance is increased. Moreover, the outermost side of the movable door does not exceed the original position range after being folded, thereby increasing the braking distance and efficiency.
[0054] The folding structure of the revolving door without display box provided by the utility model is introduced in detail above. The principle and implementation method of the utility model are explained in this article by using specific examples. The description of the above embodiments 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.
