The top rod 31 and the bottom rod 32 are connected through two connecting rods 33, and the two connecting rods 33 are in X-shaped structure. The two ends of the connecting rod 33 are respectively connected with the top rod 31 and the bottom rod 32 through a sliding block 332. The two ends of the top portion of the bottom rod 32 are respectively provided with an installation groove, and the sliding block 332 is located in the installation groove and connected with the inner side wall of the installation groove through a spring 322. The inside of the horizontal plate 13 is fixed with a motor 4 through a bolt, the driving end of the motor 4 is connected with a screw rod 41 through a key, the outer thread of the screw rod 41 is connected with a connecting seat 43, the outer side wall of the connecting seat 43 is rotatably connected with a friction rod 42 through a rotating shaft, and the top of the horizontal plate 13 is welded with an installation seat 131. The friction rod 42 penetrates through the installation seat 131 and is in contact with the inner side wall of the guide rail 2.

[0019] When the compartment 1 falls due to failure during movement in the elevator shaft, the motor 4 drives the screw rod 41 to rotate, so that the connecting seat 43 moves downward along the outer portion of the screw rod 41, and the end of the friction rod 42 is in contact with the inner side wall of the guide rail 2. The falling speed of the compartment 1 is reduced by friction, until the stop block 11 is in contact with the convex block 311. First, the pull rope 312 pulls the top rod 31 to slow down the impact force. The impact force generated by the falling of the compartment 1 can cause the pull rope 312 to break. At this time, the top rod 31 is pressed downward by the compartment 1, so that the sliding block 332 moves in the installation groove respectively, and the two connecting rods 33 are flattened. The spring 322 is compressed and shrunk to further buffer the compartment 1. By using multiple speed reduction of the compartment 1, the injury to the passengers in the compartment 1 can be minimized.

[0020] Specifically, referring to Figures 1-2 , the bottom of the outer side wall of the compartment 1 is welded with a stop block 11, and the top of the top rod 31 is welded with a convex block 311.

The convex block 311 and the stop block 11 can effectively prevent the bottom of the compartment 1 from contacting the top rod 31, and prevent the bottom of the compartment 1 from being deformed by impact.

[0021] Further, referring to Figure 3 , the inside of the installation seat 131 is rotatably connected with a rolling ball 421, and the rolling ball 421 is sleeved on the outer portion of the friction rod 42. The rolling ball 421 can limit the friction rod 42 and make the friction rod 42 move stably in the inside of the installation seat 131.

[0022] It is worth noting that, referring to Figures 1-2The bottom surface of the connecting rod 33 is welded with a balance plate 331, the balance plate 331 can be in sliding contact with another connecting rod 33, the top of the bottom rod 32 is welded with a plurality of baffle plates 321, the baffle plates 321 can be in contact with the balance plate 331 and the connecting rod 33, the balance plate 331 and the baffle plates 321 can prevent the two connecting rods 33 from tilting during the flattening process, and can make the top rod 31 move horizontally stably.

[0023] It is worth noting that, referring to Figures 1-2 The two ends of the top rod 31 are respectively fixed with a pull rope 312, the other end of the pull rope 312 is fixed with the inner side wall of the elevator shaft through a bolt, and the pull rope 312 can block the falling of the compartment 1 when it is broken.

[0024] It is worth noting that, referring to Figure 1 And Figure 3 The outer side wall of the compartment 1 is welded with a pull rod 12, two pull rods 12 are distributed on the outer side wall of each guide rail 2, the pull rod 12 is of L-shaped structure, the pull rod 12 is in sliding contact with the outer side wall of the guide rail 2, and the pull rod 12 can control the moving track of the compartment 1, so that the compartment 1 can always move in the vertical direction.
