[0033] Please refer to the following: Figures 1 to 2The present invention describes the nickel-plated stainless steel air-raid shelter door opening mechanism. The nickel-plated stainless steel air-raid shelter door opening mechanism includes a handwheel 11, a first gear 12, a second gear 13, a slider 14, and a swing rod 21. The handwheel 11 is adapted to rotate with the door body 31, opening or closing the air-raid shelter door by rotating the handwheel 11. The first gear 12 is coaxially arranged with and connected to the handwheel 11. The second gear 13 has a smaller diameter than the first gear 12, is located on one side of the first gear 12, and meshes with the first gear 12. The second gear 13 is adapted to rotate with the door body 31. The slider 14 is located below the second gear 13 and has a degree of freedom to slide along a first trajectory, which is arc-shaped and concentric with the second gear 13. The swing rod 21 slides with the slider 14 and has a degree of freedom to slide along the length direction of the swing rod 21. The extension line of the swing rod 21 along its length direction passes through the axis of the second gear 13, and its end is adapted to engage with the second gear 13.

[0034] It should be noted that in the initial state, the lever 21 is separated from the second gear 13, so that when the handwheel 11 is turned directly, the handwheel 11 can rotate normally without driving the lever 21 to rotate.

[0035] When the handwheel 11 needs to be driven to rotate via the swing arm 21, first rotate the swing arm 21 to one end of the first track; then push the swing arm 21 upward so that the end of the swing arm 21 engages with the second gear 13, and push the other end of the swing arm 21 along the first track; then, retract the swing arm 21 to separate it from the second gear 13, and push the other end of the swing arm 21 along the first track, and push the swing arm 21 upward so that the end of the swing arm 21 engages with the second gear 13. Repeat this process to drive the handwheel 11 to rotate, thus opening or closing the air-raid shelter door.

[0036] The beneficial effects of the nickel-plated stainless steel air-raid shelter door opening mechanism provided by this utility model are as follows: Compared with the prior art, the nickel-plated stainless steel air-raid shelter door opening mechanism provided by this utility model uses a smaller diameter second gear 13 to drive a larger diameter first gear 12, amplifying the force. A swing arm 21 is provided on the lower side of the second gear 13, and the swing arm 21 can be engaged or disengaged from the second gear 13 by pushing or pulling the swing arm 21, so that people who are short or have difficulty standing can easily grasp the swing arm 21. By reciprocating the swing arm 21, the second gear 13 is driven to rotate, which in turn drives the first gear 12 and the handwheel 11 to rotate, opening or closing the air-raid shelter door. Furthermore, the swing arm 21 increases the lever arm, and the diameter of the second gear 13 is smaller than the diameter of the first gear 12, thus amplifying the force applied to the swing arm 21, so that the handwheel 11 can be driven to rotate with less force to open or close the air-raid shelter door.
