[0002] As people's living standards continue to improve, many middle- and high-income people are choosing more comfortable and improved housing. For these multi-story duplexes or villas, traditional stairs can no longer meet the needs of owners. Especially for elderly people with limited mobility, climbing stairs is difficult and dangerous. Therefore, many owners have begun to install elevators in their homes.

[0003] However, during the use of the elevator, it is inevitable that malfunctions may occur, causing dangerous accidents such as the elevator falling, thereby failing to ensure the personal safety of people riding the elevator. Therefore, it is necessary to provide a safety elevator that can prevent high-speed falling to meet actual usage needs.

[0004] Chinese invention patent CN202220836171.8 discloses a fall-proof villa elevator. By installing rollers on both sides of the elevator, when the elevator falls, the rollers slide in the roller grooves on both sides of the elevator, and the spring A on one side of the roller acts as a shock absorber. At the same time, the compression of spring B provides a buffering process, and the buffering elastic ball inside the elevator frame also provides a buffering effect. Existing technologies cannot lock the elevator car when it falls, making accidents more likely.

[0032] like Figure 1-9As shown, a fall-proof villa ladder comprises a mounting frame 1, a car assembly 2 is slidably mounted on the front side of the mounting frame 1, guide rails 3 are respectively provided on the left and right sides of the mounting frame 1, a guide pulley mechanism 4 is provided at positions corresponding to the guide rails 3 on the outer wall of the car assembly 2, the guide pulley mechanism 4 is movably mounted on the guide rails 3, an anti-fall mechanism 5 is provided between the car assembly 2 and the mounting frame 1, a chain fixing seat 6 is provided on the mounting frame 1, a lifting chain is provided between the chain fixing seat 6 and the anti-fall mechanism 5, a lifting mechanism 7 is provided inside the mounting frame 1, and the lifting chain is wound around a guide mechanism 8 at the upper end of the lifting mechanism 7. The mounting frame 1 described in the present invention comprises supporting square tubes spaced apart on the left and right, a connecting cross tube is provided between the supporting square tubes, the guide rails 3 are arranged on the middle portion of the inner side of the supporting square tubes through the mounting seat, and the guide rails 3 effectively increase the overall strength of the mounting frame 1. In the present invention, the car assembly 2 is slidably mounted on the guide rail 3 via a guide pulley mechanism 4. A lifting chain pulls an anti-fall mechanism 5 disposed between the car assembly 2 and the guide rail 3. A lifting mechanism 7 drives the lifting chain upward or downward, thereby driving the car assembly 2 up and down. If the lifting chain breaks, the anti-fall mechanism 5 effectively locks the car assembly 2 to the guide rail 3, preventing the car assembly from rapidly falling and causing an accident. The present invention is simple in structure and safe and reliable.

[0033] Reference Figure 3 、 5and 8. The anti-fall mechanism 5 of the present invention includes a rod seat plate 51 arranged in the car assembly 2, a chain rod 52 is movably provided in the rod seat plate 51, the upper end of the chain rod 52 is connected to one end of the lifting chain, and a first connecting rod 53 is hinged at the lower end of the chain rod 52. A connecting slot 54 is provided in the car assembly 2 on the lower side of the rod seat plate 51, which passes through the inside and outside of the car assembly 2. An articulated seat 55 is provided on the car assembly 2 inside the communicating slot 54. A second connecting rod 56 is provided inside the car assembly 2. The first end of the second connecting rod 56 extends through the connecting slot 54. The second end of the second connecting rod 56 is hinged to the lower end of the first connecting rod 53. A tension spring 57 is provided between the second end of the second connecting rod 56 and the car assembly 2. A third pull rod 58 is connected to the first end of the second connecting rod 56. A safety clamp 59 capable of locking the guide rail 3 is provided at a position corresponding to the guide rail 3 on the outside of the car assembly 2. The lower end of the third pull rod 58 is connected to the driving end of the safety clamp 59. The safety clamp 59 of the present invention is fixed to the car assembly 2. When the chain is normally not broken, the safety clamp 59 slides up and down on the guide rail 3 following the car assembly 2. When the chain breaks, the first connecting rod 53 loses the tension of the lifting chain. Under the action of the tension spring 57, the second end of the second connecting rod 59 moves downward, driving the first end of the second connecting rod 56 to pull the third connecting rod 58 upward, thereby causing the safety clamp 59 to lock the guide rail 3.

[0034] Reference Figure 9 The safety clamp 59 of the present invention includes a clamp seat 591 fixedly connected to the outside of the car assembly 2. A slide groove 592 is provided in the clamp seat 591. The guide rail 3 is disposed in the slide groove 592.
