[0027] The car 11 is raised and lowered by the lifting mechanism 3. When it is lifted to a specified height, the lifting mechanism 3 is limited by the limiting mechanism 4 so that the lifting mechanism 3 cannot rotate, thereby ensuring the safety of the car 11. When the car 11 falls accidentally, the protection mechanism 2 protects the car 11 to reduce the impact on the car 11.

[0028] like Figure 2 , Figure 3 As shown, the front and rear parts of the left end of the car 11 are fixedly connected to the limit block 13, the outer wall of the limit block 13 is slidably connected to the inner wall of the partition 12, the front and rear ends of the car 11 are fixedly connected to the limit block 2 14, the outer wall of the limit block 2 14 is slidably connected to the inner wall of the elevator shaft 1, and the outer shapes of the limit block 13 and the limit block 2 14 are both T-shaped.

[0029] When the car 11 moves, it drives the limit block 13 to slide on the inner wall of the partition 12, and the limit block 13 limits the car 11, so that the car 11 will not derail when moving. At the same time, the car 11 drives the limit block 2 14 to slide on the inner wall of the elevator shaft 1, and the limit block 2 14 guides the car 11, so that the car 11 slides more smoothly, which plays the effect of limiting and guiding, and increases the stability of the car 11.

[0030] like Figure 2 As shown, a spring 22 is movably sleeved on the outer wall of the damper 21, a protection plate 23 is fixedly connected to the top of the damper 21, and the outer wall of the protection plate 23 is slidably connected to the bottom of the inner cavity of the elevator shaft 1.

[0031] When the car 11 falls due to an accident, the bottom end of the car 11 contacts the top end of the protection plate 23. The protection plate 23 drives the damper 21 and the spring 22 to contract. The damper 21 and the spring 22 absorb the impact force, reducing the impact on the car 11, thereby protecting the car 11.

[0032] like Figure 2 , Figure 4As shown, the output end of the motor 31 is fixedly connected to a threaded rod 32, the top of the threaded rod 32 is rotatably connected to the top of the inner cavity of the elevator shaft 1, the bottom of the threaded rod 32 is fixedly connected to a latch tooth 321 in a circular array, the bottom of the threaded rod 32 is threadedly connected to a slider 33, the outer wall of the slider 33 is slidably connected to the inner wall of the partition 12, and the right end of the slider 33 is fixedly connected to the rear end of the car 11.

[0033] The threaded rod 32 is driven to rotate by the motor 1 31 , so that the slider 1 33 slides on the outer wall of the threaded rod 32 . At the same time, the slider 1 33 drives the car 11 to move synchronously, so that the car 11 slides in the inner cavity of the elevator shaft 1 .

[0034] like Figure 2 , Figure 4 As shown, the front and rear ends of slider 1 33 are fixedly connected to slider 2 34, the inner wall of slider 2 34 is slidably connected to a guide rod 35, one end of the guide rod 35 is fixedly connected to one end of the inner cavity of the elevator shaft 1, the outer wall of slider 2 34 is slidably connected to the inner wall of the partition 12, and the right end of slider 2 34 is fixedly connected to the left end of the car 11.

[0035] When the slider 1 33 slides, it drives the slider 2 34 to slide on the outer wall of the guide rod 35 , and the slider 1 33 is limited and guided by the slider 2 34 and the guide rod 35 , so that the slider 1 33 slides more smoothly.

[0036] like Figure 2 , Figure 5 As shown, the output end of the motor 2 41 is fixedly connected with a bidirectional threaded rod 42, the outer wall of the bidirectional threaded rod 42 is rotatably connected with a fixed box 43, the bottom end of the fixed box 43 is fixedly connected with the top end of the support plate 15, the front and rear parts of the outer wall of the fixed box 43 are threadedly connected with a connecting rod 44, the outer wall of the connecting rod 44 is slidably connected with the inner wall of the fixed box 43, the right end of the connecting rod 44 is fixedly connected with a limiting ring 45, and the shape of the limiting ring 45 is an arc-shaped tooth.

[0037] When the car 11 reaches the specified height, the motor 2 41 drives the bidirectional threaded rod 42 to rotate, so that the connecting rod 44 slides on the outer wall of the bidirectional threaded rod 42, driving the limit ring 45 to move synchronously, so that the outer wall of the limit ring 45 engages with the outer wall of the latch tooth 321, thereby limiting the position of the threaded rod 32 and preventing the threaded rod 32 from rotating, thereby ensuring that the car 11 will not move, ensuring the safety of the car 11, and achieving the effect of increasing safety.

[0038] The working principle of the utility model is as follows: when in use, by pressing the button of the desired floor, the motor 2 41 is started, driving the bidirectional threaded rod 42 to rotate, so that the connecting rod 44 slides on the outer wall of the bidirectional threaded rod 42, and the connecting rod 44 drives the limiting ring 45 to move synchronously, so that the outer wall of the limiting ring 45 is away from the outer wall of the latch 321, thereby canceling the limit on the threaded rod 32, and at the same time, when the door of the car 11 is closed, the motor 2 41 stops rotating at the same time. If the door of the car 11 is not completely closed and is opened again, the motor 2 When the door of the car 11 is closed, the motor 1 31 is started at the same time, and the motor 1 31 drives the threaded rod 32 to rotate, so that the slider 1 33 slides on the outer wall of the threaded rod 32, and the slider 1 33 drives the slider 2 34 to slide on the outer wall of the guide rod 35, and the slider 1 33 is limited by the slider 2 34 and the guide rod 35. The positioning and guiding of the slider 1 33 makes the slider 1 33 slide more smoothly. At the same time, the slider 1 33 and the slider 2 34 drive the car 11 to move synchronously, so that the car 11 drives the limit block 1 13 to slide on the inner wall of the partition 12. The limit block 13 limits the car 11, so that the car 11 will not derail when moving. At the same time, the car 11 drives the limit block 2 14 to slide on the inner wall of the elevator shaft 1, and the limit block 2 14 guides the car 11, so that the car 11 slides more smoothly, which plays a role in limiting and guiding, and increases the safety of the car 11. Stability. When the car 11 stops, the limit ring 45 re-engages with the latch tooth 321, thereby limiting the threaded rod 32 and preventing the threaded rod 32 from rotating, thereby ensuring that the car 11 does not move and the safety of the car 11 is ensured. When the car 11 falls due to an accident, the bottom end of the car 11 contacts the top end of the protection plate 23, and the protection plate 23 drives the damper 21 and the spring 22 to contract. The damper 21 and the spring 22 absorb the impact force and reduce the impact on the car 11, thereby greatly improving the user experience.
