All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-6 As shown, this embodiment provides a civil defense door assembly for a rail transit station, including: a slide rail 11, a connector, and a door body 30. The slide rail 11 is adapted to connect with the step surface 1 and extends along the width direction of the safety passage. The top of the connector is provided with a sliding part, which is slidably connected to the slide rail 11. The bottom of the connector is provided with a first rotating part, and a second rotating part is provided inside the door body 30. The first rotating part is located inside the door body 30 and rotates in cooperation with the second rotating part.

[0028] In some embodiments, the rail transit station is provided with a safety passage. The top of the safety passage is provided with a step surface 1 extending in the width direction of the safety passage. A slide rail 11 is installed on the step surface 1 and extends along the width direction of the safety passage to provide a track for the movement of the door 30. The top of the connector is provided with a sliding part, which is slidably connected to the slide rail 11, so that the connector can move along the slide rail 11. The bottom of the connector is provided with a first rotating part, and a second rotating part is provided inside the door 30. The first rotating part of the connector is located inside the door 30, and the first rotating part and the second rotating part inside the door 30 rotate in cooperation to realize the relative rotation between the door 30 and the connector.

[0029] Understandably, the sliding connection between the sliding part at the top of the connector and the slide rail 11 allows the connector to move freely along the slide rail 11 in the width direction of the safety passage, thereby allowing the door 30 to move freely along the width direction of the safety passage. It should be noted that the sliding connection can be achieved in various ways, such as the cooperation between the roller 22 and the track, or the cooperation between the slider and the groove, etc. There are no restrictions here, as long as it can satisfy the sliding of the door 30 relative to the safety passage.

[0030] The first rotating part at the bottom of the connector rotatably engages with the second rotating part inside the door body 30, allowing the door body 30 to rotate relative to the connector. It should be noted that the rotatable engagement can be achieved through the fit between a shaft and a hole, bearing connection, etc., and is not limited here, so that the door body 30 can rotate flexibly when opening or closing.

[0031] It is worth mentioning that the air defense door assembly of this application can achieve multiple states of opening and closing through the ability of the door body 30 to slide and rotate relative to the safety passage. That is, the door body 30 of this application has more ways of opening and closing. At the same time, the connector of this application is located between one end and the other end of the length direction of the door body 30. In case of emergency and there are opposing flows of people on both sides of the safety passage, the door body 30 of this application can rotate relative to the connector, so that the opposing flows of people can pass through on both sides of the door body 30 respectively, so as to ensure that the air defense door assembly can be opened quickly, avoiding congestion and accidents. Thus, the air defense door assembly of this application can adapt to complex and ever-changing actual use scenarios.

[0032] According to the present invention, the air defense door assembly for rail transit stations has a sliding part at the top of the connector that is suitable for cooperating with the slide rail 11, and a first rotating part at the bottom of the connector that is suitable for cooperating with the second rotating part of the door body 30. This allows the door body 30 to slide and rotate relative to the safety passage, so as to flexibly adjust the position of the door body 30 according to actual needs. This allows the door body 30 to be easily opened and closed, facilitating the passage of personnel and materials, improving the efficiency of the safety passage, and meeting the need for rotating and storing the door body 30.

[0033] According to some embodiments of the present invention, the connector includes a mounting plate 21, a roller 22 is provided on the top of the mounting plate 21, the roller 22 is constructed as a sliding part, a rotatable rotating rod 23 is provided on the bottom of the mounting plate 21, the rotating rod 23 is constructed as a first rotating part, and a hanger connected to the door body 30 is provided inside the door body 30, the hanger is constructed as a second rotating part.

[0034] In some embodiments, the connector is mainly composed of a mounting plate 21. A roller 22 is mounted on the top of the mounting plate 21. The roller 22 serves as a sliding part and is used to achieve a sliding connection with the slide rail 11. A rotatable rotating rod 23 is provided at the bottom of the mounting plate 21. The rotating rod 23 serves as a first rotating part. A hanger connected to the door body 30 is provided inside the door body 30. The hanger serves as a second rotating part and is adapted to rotate and cooperate with the rotating rod 23 of the connector.

[0035] Understandably, the roller 22 on the top of the mounting plate 21 contacts the slide rail 11. When the door 30 is pushed by an external force, the roller 22 rolls along the slide rail 11. Due to the small rolling friction, the door 30 can move relatively easily along the slide rail 11 in the width direction of the safety passage. The rotating rod 23 at the bottom of the mounting plate 21 and the hanger inside the door 30 achieve relative rotation through a rotating engagement. The rotating rod 23 can rotate around its own axis inside the hanger. When it is necessary to open or close the door 30, the door 30 rotates around the rotating rod 23 as the axis, thereby realizing the opening and closing action of the door 30.

[0036] It should be noted that this application uses roller 22 as the sliding part, and uses rolling friction instead of sliding friction, which greatly reduces the friction force, making the movement of the door 30 on the slide rail 11 smoother, reducing energy loss and wear, and extending the service life of the air defense door assembly. Moreover, the rotational cooperation design between the rotating rod 23 and the hanger makes the opening and closing operation of the door 30 more flexible, and can complete the opening and closing action quickly and smoothly, improving the ease of use and response speed of the door 30. Of course, by integrating the roller 22 and the rotating rod 23 together through the mounting plate 21 to form a connector, the structure of the entire air defense door assembly is more compact, which is convenient for installation and maintenance, and also saves space.

[0037] According to some embodiments of the present invention, the outer peripheral wall of the roller 22 is provided with a rolling groove extending in the circumferential direction, and part of the slide rail 11 is disposed in the rolling groove.

[0038] Understandably, when the roller 22 rolls on the slide rail 11, since the slide rail 11 is partially embedded in the rolling groove of the roller 22, the inner wall of the rolling groove will limit the outer wall of the slide rail 11, allowing the roller 22 to move stably along the predetermined path of the slide rail 11 during rolling, and preventing it from easily detaching from the slide rail 11. At the same time, the cooperation between the rolling groove and the slide rail 11 also increases the contact area between the roller 22 and the slide rail 11, dispersing the pressure between the roller 22 and the slide rail 11, making the rolling of the roller 22 more stable.

[0039] According to some embodiments of the present invention, the slide rail 11 includes a vertical plate 111, a first horizontal plate 112 is provided at the top of the vertical plate 111 and the first horizontal plate 112 is located in the rolling groove, and a second horizontal plate 113 is provided at the bottom of the vertical plate 111 and the second horizontal plate 113 is adapted to be connected to the stepped surface 1.

[0040] It is understood that the first horizontal plate 112 is embedded in the rolling groove of the roller 22. When the roller 22 rolls, the side wall of the rolling groove cooperates with the first horizontal plate 112 to restrict the left and right displacement of the roller 22 in the horizontal direction, ensuring that the roller 22 can only roll along the extension direction of the slide rail 11 (i.e. the width direction of the safety passage), effectively preventing the roller 22 from derailing, thereby realizing the stable and accurate movement of the door 30.

[0041] The second horizontal plate 113 is connected to the step surface 1, providing stable support for the entire slide rail 11, enabling the slide rail 11 to withstand the weight of the door body 30 and connecting parts, as well as various forces generated during operation. It is worth mentioning that the second horizontal plate 113 is connected to the step surface 1 via the mounting bracket 12, and the second horizontal plate 113 is located at the end of the mounting bracket 12 furthest from the step surface 1. This allows a gap to be formed between the slide rail 11 and the step surface, preventing interference from the step surface 1 when the roller 22 overlaps with the slide rail 11, while ensuring smooth movement of the roller 22 relative to the slide rail 11.

[0042] According to some embodiments of the present invention, the vertical plate 111, the first horizontal plate 112, and the second horizontal plate 113 form a mating space open toward the stepped surface 1. The roller 22 is rotatably connected to the mounting plate 21 via a rotating shaft 24. A baffle 25 is provided at one end of the rotating shaft 24 away from the mounting plate 21. The free end of the baffle 25 extends toward the second horizontal plate 113 and is provided with a flange 251. At least a portion of the flange 251 is located within the mating space and can selectively abut against the vertical plate 111 and / or the first horizontal plate 112.

[0043] In some embodiments, when the roller 22 rolls on the slide rail 11, the flange 251 moves relative to the roller 22 within the mating space. When the roller 22 tends to disengage from the slide rail 11, the flange 251 will abut against the vertical plate 111 and / or the first horizontal plate 112, preventing the roller 22 from rotating circumferentially along the slide rail 11, thereby preventing the roller 22 from disengaging from the slide rail 11. This further improves the stability of the mating between the roller 22 and the slide rail 11, ensuring that the door 30 moves stably in the width direction of the safety passage, and ensuring the reliability of the operation of the blast door assembly.

[0044] According to some embodiments of the present invention, the hanger includes a connecting plate 31, which is connected to the door body 30. The top of the mounting plate 21 is provided with a hanger body, and the end of the hanger body away from the connecting plate 31 is provided with a rotating hole. The end of the rotating rod 23 away from the mounting plate 21 is rotatably disposed in the rotating hole.

[0045] In some embodiments, the connecting plate 31 is connected to the door body 30 to fix the hanger on the door body 30. One end of the rotating rod 23 is inserted into the rotating hole of the hanger body to form a rotating connection point. When the door body 30 needs to be opened or closed, the door body 30 drives the hanger to rotate around the rotating rod 23 with the rotating rod 23 as the axis, so as to realize the opening and closing action of the door body 30.

[0046] Therefore, the connection method between the connecting plate 31 and the door body 30 ensures a firm connection between the hanger and the door body 30, enabling the hanger to stably bear the weight of the door body 30 and various forces generated during the opening and closing of the door body 30. The cooperation between the rotating rod 23 and the rotating hole reduces problems such as jamming or damage to the door body 30 caused by poor rotation.

[0047] According to some embodiments of the present invention, the hanger body includes a surrounding plate 32, one side wall of the surrounding plate 32 is provided with a rotating hole, and the side wall of the surrounding plate 32 opposite to the rotating hole is connected to the connecting plate 31.

[0048] In some embodiments, the bottom end of the rotating rod 23 extends through the rotating hole into the enclosure 32 and is adapted to cooperate with the fastener, thereby connecting the rotating rod 23 to the hanger body. This ensures the stability of the connection between the rotating rod 23 and the hanger body, simplifies the connection method between the rotating rod 23 and the hanger body, and improves the connection efficiency between the rotating rod 23 and the hanger body.

[0049] According to some embodiments of the present invention, a transition plate 321 is provided on the side wall of the enclosure 32 opposite to the rotating hole. The transition plate 321 extends toward the connecting plate 31 and is provided with a first mating hole. The connecting plate 31 is provided with a connecting ear 311 extending toward the enclosure 32. The connecting ear 311 is provided with a second mating hole opposite to the first mating hole. The screw 322 passes through the first mating hole and the second mating hole and engages with the nut to connect the transition plate 321 and the connecting ear 311.

[0050] In some embodiments, the connecting plate 31 is provided with two connecting ears 311, which are spaced apart from each other. The adapter plate 321 is located between the two connecting ears 311, and the first mating hole of the adapter plate 321 and the second mating holes of the two connecting ears 311 are directly opposite each other. The screw 322 passes through the second mating hole of one of the connecting ears 311, the first mating hole of the adapter plate 321 and the second mating hole of the other connecting ear 311 in sequence and then engages with the nut, thereby connecting the enclosure plate 32 and the connecting plate 31.

[0051] Understandably, the aligned design of the first and second mating holes provides an accurate position for the screw 322 to pass through. Through the threaded engagement of the screw 322 and the nut, a tightening force is generated, which firmly fixes the adapter plate 321 and the connecting ear 311 together, thereby achieving a reliable connection between the enclosure plate 32 and the connecting plate 31.

[0052] When the door 30 is subjected to external force, the force is transmitted to the connecting ear 311 through the connecting plate 31, and then to the adapter plate 321 through the connection structure of the screw 322 and nut, and then to the enclosure 32 and the entire hanger body. This can effectively disperse and bear the various forces generated by the door 30, and ensure the stability of the hanger structure.

[0053] According to some embodiments of the present invention, the rotating rod 23 is rotatably connected to the mounting plate 21 via the first rotating bearing 26, and the roller 22 is rotatably connected to the mounting plate 21 via the second rotating bearing 27.

[0054] In some embodiments, the inner ring of the first rotary bearing 26 is fixedly connected to the rotating rod 23, and the outer ring of the first rotary bearing 26 cooperates with the mounting plate 21. When an external force is applied to the door body 30 and drives the rotating rod 23 to rotate, the rotating rod 23 passes through the inner ring of the first rotary bearing 26, causing the rolling elements to roll within the outer ring, thereby realizing the rotation of the rotating rod 23 relative to the mounting plate 21. The first rotary bearing 26 converts sliding friction into rolling friction, significantly reducing the friction between the rotating rod 23 and the mounting plate 21, reducing component wear, extending the service life of the rotating rod 23 and the mounting plate 21, and reducing maintenance costs.

[0055] The inner ring of the second rotary bearing 27 is fixedly connected to the shaft of the roller 22, and the outer ring of the second rotary bearing 27 mates with the mounting plate 21. When the roller 22 rolls on the slide rail 11, the inner ring of the second rotary bearing 27 causes the rolling elements to roll within the outer ring, thus realizing the rotation of the roller 22 relative to the mounting plate 21. The second rotary bearing 27 converts sliding friction into rolling friction, significantly reducing the friction between the roller 22 and the mounting plate 21, reducing component wear, extending the service life of the roller 22 and the mounting plate 21, and reducing maintenance costs.

[0056] According to some embodiments of the present invention, a connector corresponds to a door 30. The door 30 is constructed as a plurality of doors spaced apart along the extension direction of the slide rail 11. The plurality of doors 30 cooperate to divide the safety passage into a first passage and a second passage spaced apart along the extension direction of the safety passage.

[0057] In some embodiments, each door 30 is equipped with an independent connector, enabling each door 30 to move and rotate independently on the slide rail 11, ensuring that the movement of each door 30 can be precisely controlled and stably supported. Multiple doors 30 are arranged at intervals along the extension direction of the slide rail 11, and the multiple doors 30 cooperate with each other to divide the originally continuous safety passage into a first passage and a second passage.

[0058] It is understood that the safety passage is provided with a hidden door compartment 2, which is connected to one side wall of the safety passage in the width direction. The civil defense door component of this application provides multiple door bodies 30, so that the length of each door body 30 can be smaller, thereby making it easier to accommodate the door body 30 in the hidden door compartment 2.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
