In this embodiment, the connection method between the two is bolt connection.
[0029] Below the mounting plate 1, there are a fixed plate 2 and a rotating plate 3 which are sequentially distributed along the normal movement direction of the hanging chair. The fixed plate 2 and the rotating plate 3 are made of steel. Figure 1 As shown, from left to right is the normal movement direction of the hanging chair, then the fixed plate 2 is located on the left side of the rotating plate 3, and the fixed plate 2 and the rotating plate 3 are parallel to each other. Specifically, the rotating plate 3 is a rectangular plate structure, the rotating plate 3 is rotatably connected to the mounting plate 1, and the bottom of the rotating plate 3 is located on the movement trajectory of the hanging chair; two coaxial mounting rings 4 are fixedly provided on the mounting plate 1. In this embodiment, the outer side wall of the mounting ring 4 is fixedly connected to the surface of the mounting plate 1, and the connection method of the two is welding; the top end of the rotating plate 3 is fixedly connected to the rotating shaft 301, and the two ends of the rotating shaft 301 extend into the corresponding mounting ring 4 and are rotatably connected to the mounting ring 4. The edge of the rotating plate 3 is fixedly connected to the outer side wall of the rotating shaft 301, and the connection method of the two is welding; as shown Figure 2 As shown, the rotating shaft 301 is a stepped shaft, the middle of the rotating shaft 301 is a large diameter section, and the two ends of the rotating shaft 301 are small diameter sections. The diameter of the small diameter section is slightly smaller than the inner diameter of the mounting ring 4, so that a rotation margin for the small diameter section is formed between the outer wall of the small diameter section and the inner wall of the mounting ring 4; the diameter of the large diameter section is larger than the inner diameter of the mounting ring 4 and smaller than the outer diameter of the mounting ring 4, so that a rotation margin for the rotating shaft 301 is formed between the outer wall of the rotating shaft 301 and the mounting plate 1.
[0030] The fixed plate 2 is a rectangular plate-shaped structure. The fixed plate 2 is located on one side of the rotating plate 3 and is vertically fixedly connected to the mounting plate 1.

The setting of the rubber pad cushions the impact force of the hanging chair on the rotating plate 3, thereby improving the life of the rotating plate 3.
[0033] In this embodiment, at least one reinforcing plate 203 is disposed between the fixed plate 2 and the mounting plate 1. Reinforcing plate 203 is located on the side of the fixed plate 2 facing away from the rotating plate 3. There are two reinforcing plates 203, evenly distributed across the width of the mounting plate 1.

The rotating plate 3 and the slider 5 are connected in such a way that two coaxial mounting rings 4 are fixedly provided on the slider 5. In this embodiment, the outer side wall of the mounting ring 4 is fixedly connected to the surface of the slider 5, and the two are connected by welding; the top end of the rotating plate 3 is fixedly connected to a rotating shaft 301, and the two ends of the rotating shaft 301 extend into the corresponding mounting ring 4 and are rotatably connected to the mounting ring 4. The edge of the rotating plate 3 is fixedly connected to the outer side wall of the rotating shaft 301, and the two are connected by welding; as shown Figure 6 As shown, the rotating shaft 301 is a stepped shaft, the middle of the rotating shaft 301 is a large diameter section, and the two ends of the rotating shaft 301 are small diameter sections.

[0038] The compression spring 6 is located between the baffle 7 and the slider 5. One end of the compression spring 6 is fixedly connected to the slider 5, and the other end of the compression spring 6 is fixedly connected to the baffle 7. When the hanging chair does not pass through the device, Figure 3 As shown, the rotating plate 3 is in a vertical state under the action of gravity, and the compression spring 6 presses the slider 5 against the fixed plate 2; when the chairlift operates normally to the device, as shown in FIG. Figure 4 As shown, the chair passes under the fixed plate 2 and contacts the rotating plate 3, pushing the rotating plate 3 to rotate counterclockwise, and finally passes over the rotating plate 3. Figure 5 As shown, the hanging chair moves from right to left and collides with the lower part of the rotating plate 3, pushing the slider 5 to move toward the baffle 7. The compression spring 6 is in a compressed state, which plays a buffering role, reducing the force at the connection between the rotating plate 3 and the slider 5, and avoiding breakage at this position.
