[0030] 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.
[0031] Reference Figures 1-5, an embodiment provided by the present utility model: a protective structure for an elevator door, including a housing 1. The housing 1 should be made of hard metal material to protect the car 3. Inside the housing 1, a motor 11 is fixedly connected, which is used to drive the opening and closing of the elevator door 2. The output end of the motor 11 is fixedly connected with a first gear 12. Through the first gear 12, a second rack 13 on its outer wall is engaged and moved, converting the rotation of the motor 11 into movement. Inside the housing 1, a first chute 5 is provided to facilitate the sliding of a slider 6 slidably connected inside the first chute 5, effectively restricting the running track of the slider 6. The second rack 13 is arranged on the outer wall of the slider 6, enabling the second rack 13 to drive the sliding of the slider 6. A second gear 14 is rotatably connected to the outer wall of the slider 6. When the slider 6 slides, since one side of the second gear 14 is engaged with the outer wall of the first rack 9, the second gear 14 will roll on the first rack 9 provided inside the housing 1, realizing the rotation of the second gear 14. Inside the housing 1, a third chute 10 is provided to provide a movement track for the elevator door 2. The elevator door 2 is slidably connected inside the third chute 10, restricting the running track of the elevator door 2 to achieve the designed effect. A third rack 15 is arranged at the bottom of the elevator door 2, and the outer wall of the third rack 15 will be engaged with the other side of the second gear 14, enabling the elevator door 2 to be driven by the second gear 14 to operate. Inside the elevator door 2, a cross member 8 is provided. The cross member 8 is also arranged inside the housing 1, so that both are connected to the cross member 8 and rotate therewith.
[0032] Inside the elevator door 2, a horizontal groove 16 is provided, enabling a first rotating shaft 17 rotatably connected to one side of the cross member 8 to be slidably connected inside the horizontal groove 16, facilitating the deformation of the cross member 8. Similarly, a second rotating shaft 18 rotatably connected to the other side of the cross member 8 is slidably connected inside a second chute 7 provided inside the housing 1, also to adapt to the deformation of the cross member 8. An anti-collision strip 4 is fixedly connected to the outer wall of the elevator door 2, effectively reducing the frictional collision between two elevator doors 2. An electric push rod 19 is fixedly connected inside the housing 1, which can drive the movement of a movable clamp 20. The output end of the electric push rod 19 is fixedly connected with a push block 21 to facilitate adapting to its connection relationship with the movable clamp 20. A rotating column 22 is slidably connected between the push blocks 21, and the outer wall of the rotating column 22 is rotatably connected with the movable clamp 20 to better control the operation of the movable clamp 20. A car 3 is fixedly connected inside the housing 1, which can be made of shock-absorbing material to optimize the sensory experience of the passengers. The movable clamp 20 is rotatably connected to the outer wall of the car 3, providing a fulcrum for the movable clamp 20, enabling the movable clamp 20 to rotate and snap into the gap of the elevator door 2 to prevent the elevator door 2 from opening during operation.
[0033] Working principle: When the elevator door 2 closes, the motor 11 drives the gear one 12 at its output end to rotate. The gear one 12 drives the rack two 13 meshing with it to slide. Then, the slider 6 connected to the rack two 13 will slide in the chute one 5 opened inside the housing 1, causing the gear two 14 on the outer side wall of the slider 6 to roll on the rack one 9 meshing with it, and the gear two 14 drives the rack three 15 also meshing with it to slide. Since the rack three 15 is connected to the elevator door 2, it will also cause the elevator door 2 to slide in the chute three 10 opened inside the housing 1, enabling the elevator door 2 to close. When the elevator door 2 closes, the anti-collision strip 4 reduces the buffer. This opening and closing mechanism is more stable and can withstand greater impact force. When the elevator door 2 closes, it will pull the gallows 8 to expand and contract, which can further reinforce the elevator door 2 and increase the ability of the elevator door 2 to withstand impacts. The rotating shafts two 18 on both sides of the gallows 8 and the rotating shaft one 17 will slide in the horizontal groove 16 and the chute two 7 respectively to realize the opening and closing of the gallows 8. After the elevator door 2 closes, the electric push rod 19 will start, and the push block 21 will push the movable clip 20 to rotate, causing the movable clip 20 to snap into the gap of the elevator door 2 to prevent the elevator door 2 from opening during operation.
[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
