[0032] like Figure 1-4 As shown, a chain-driven slide rail civil air defense door comprises a civil air defense door frame 1, a guide rail 2, a chain-driven suspension mechanism 3 and a civil air defense door body 4;

[0033] The civil air defense door frame 1 is pre-buried in the wall of the civil air defense door frame 1, and the civil air defense door frame 1 is provided with a door opening 10;

[0034] The guide rail 2 is arranged on the upper part of the civil air defense door frame 1;

[0035] The chain-driven suspension mechanism 3 is disposed on the guide rail 2, and the chain-driven suspension mechanism 3 is used to suspend and guide the civil air defense door body 4 to move along the length direction of the guide rail 2;

[0036] The chain drive suspension mechanism 3 includes a support frame 31, a support wheel 32, a sprocket assembly 33, a suspension assembly 34 and an annular traction chain 35;

[0037] The support wheel 32 is arranged inside the support frame 31 and is meshedly connected with the sprocket assembly 33. The suspension assembly 34 is arranged outside the support frame 31. The suspension assembly 34 is used to suspend the civil defense door body 4. The power input end of the sprocket assembly 33 is provided with the annular traction chain. The sprocket assembly 33 is driven by the annular traction chain 35. The drive of the sprocket assembly 33 is used to drive the support wheel 32 to move along the guide rail 2. The movement of the support wheel 32 is used to drive the civil defense door body 4 on the suspension assembly 34 to open and close the door opening 10.

[0038] Specifically, the civil air defense door body 4 is suspended on the suspension assembly 34, and the sprocket assembly 33 is driven by manually pulling the annular traction chain 35 in different directions, and the support wheel 32 is driven to move along the guide rail 2, so that the door body can be easily driven to move along the guide rail 2 to open and close the civil air defense door, without using electricity or other energy, and the operation is simple and convenient. At the same time, the annular traction chain 35 is used to drive the sprocket assembly 33 and the suspension assembly 34, etc., to ensure the stability and safety of the civil air defense door, and avoid the problems of the civil air defense door falling off or running off during the movement.

[0039] To further explain, since the civil defense door frame 1 is embedded in the reinforced concrete civil defense door frame 1 wall at the entrance connecting the civil defense project with the large commercial center, it can be a passage for personnel to enter and exit the civil defense project and the large commercial center in normal times. In wartime, the civil defense project can be blocked by the civil defense door body 4 to form an effective enclosure structure to ensure the safety of personnel sheltered inside the civil defense project.

[0040] In summary, the chain-driven sliding rail civil air defense door provided in the present application has the advantages of simple and convenient operation, safety and reliability, strong adaptability, etc., and can be widely used in various large entrances and exits that need to be protected and sealed.

[0041] Further explanation, the chain drive suspension mechanism 3 and the civil air defense door body 4 are arranged in one-to-one correspondence, and the civil air defense door body 4 is provided with at least one group;

[0042] The guide rail 2 is arranged in an L-shape, and the length of the guide rail 2 is greater than the width of the civil air defense door frame 1 .

[0043] Since the guide rail 2 is arranged in an L-shape, and the length of the guide rail 2 is greater than the width of the civil air defense door frame 1, one end of the guide rail 2 is mounted on the top of the civil air defense door frame 1, and the other end of the guide rail 2 is mounted on the reinforced concrete side wall of the door opening 10. Therefore, when the door opening 10 of the civil air defense door needs to be opened, multiple civil air defense door bodies 4 are transferred to the side of the door opening 10 for folding and placement, saving stacking space; when the door opening 10 of the civil air defense door needs to be closed, multiple civil air defense door bodies 4 are transferred to the door opening 10 position in sequence to block the door opening 10 of the door frame, so that the civil air defense project forms a complete enclosure structure.

[0044] To further illustrate, a support rod 36 is disposed on the support frame 31, the support wheel 32 is sleeved on the outer periphery of the support rod 36, and a bearing is disposed between the support wheel 32 and the support rod 36;

[0045] The support wheel 32 is H-shaped, and the outer diameter at both ends of the support wheel 32 is larger than the outer diameter in the middle. The outer periphery in the middle of the support wheel 32 forms a matching portion 321 that contacts the surface of the guide rail 2. The outer peripheries at both ends of the support wheel 32 are provided with external teeth 37, and the external teeth 37 are meshed and connected with the sprocket assembly 33.

[0046] In this embodiment, since the outer diameters at both ends of the support wheel 32 are larger than the outer diameter in the middle, the outer diameters at both ends of the support wheel 32 play a guiding role, so that the middle outer diameter of the support wheel 32 always keeps rolling along the guide rail 2 without deviation or derailment.

[0047] To further illustrate, the sprocket assembly 33 includes a driving wheel 331, a transmission rod 332 and a sprocket 333;

[0048] The driving wheel 331 is disposed inside the support frame 31, and the driving wheel 331 is meshed and connected with the support wheel 32;

[0049] One end of the transmission rod 332 is transmission-connected to the driving wheel 331 , and the other end of the transmission rod 332 extends out of the support frame 31 and is fixedly connected to the sprocket 333 . The outer periphery of the sprocket 333 is meshedly connected to the annular traction chain 35 .

[0050] Compared with other transmission modes, the transmission efficiency of the sprocket 333 mechanism and the annular traction chain 35 is higher, and the accumulated kinetic energy and rotational force can be accurately transmitted to the next mechanical component, thereby reducing energy loss and transmission error.

[0051] To further illustrate, the suspension assembly 34 includes a suspension bracket 341 and a universal rotating ring 342;

[0052] The hanging bracket 341 is fixed to the outside of the supporting frame 31 , the rotating end of the universal rotating ring 342 is fixed to the hanging bracket 341 , and the hanging end of the universal rotating ring 342 is installed with the civil air defense door body 4 .

[0053] In this embodiment, the civil defense door body 4 is hung on the universal rotating ring 342 of the suspension assembly 34. This is because the universal rotating ring 342 is a tool used for lifting, and it can rotate freely, so that the suspension assembly 34 and the civil defense door body 4 can be easily connected, thereby improving the safety of opening / closing and moving the civil defense door.

[0054] Further explanation, the guide rail 2 is made of a light steel rail. In this embodiment, the guide rail 2 is made of a light steel rail, which has low manufacturing cost, convenient maintenance and good economy.

[0055] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
