Figure 2 The figure is a schematic diagram of the structure of the use state of an embodiment of a crank arm connection device for an outdoor elevator and a staircase of the present invention. Figure 1-2 As shown, a crank arm connection device for an outdoor elevator and a staircase includes a connection platform and a controller. The connection platform is located between the entrance 3 of the elevator 1 and the entrance of the staircase 4. The entrance 3 of the elevator 1, the connection platform and the entrance of the staircase 4 are on the same horizontal plane. The entrance 3 of the elevator 1 and the entrance of the staircase 4 are connected through the connection platform, and the entrance can be directly reached without climbing the staircase 4. In order to facilitate the use of the elevator 1, the opening on the transfer platform of the staircase 4 can be retained, and the entrance 3 is opened directly above the opening of the transfer platform. The connection platform includes a connection plate 1 5 and a connection plate 2 6, and both the connection plate 1 5 and the connection plate 2 6 are steel plates. One end of the connection plate 1 5 is hinged to the wall 2 at the entrance 3 through a hinge, and the other end is hinged to the connection plate 2 6 through a hinge.

[0022] Figure 3 FIG. 1 is a transmission structure diagram of an embodiment of a crank arm connection device for an outdoor elevator 1 and a staircase 4 according to the present invention. Figure 3 As shown, the wall 2 is provided with a mounting groove 10 along the length direction of the connecting platform, and a screw rod 9 is provided in the mounting groove 10. One end of the screw rod 9 is rotatably connected to the end of the mounting groove 10 through a bearing, and the other end passes through the wall 2 and is connected to the motor 7 through a reducer 8. A hole is provided on the wall 2 for the screw rod 9 to pass through, and the diameter of the hole is not less than the diameter of the screw rod 9, so that the screw rod 9 can rotate freely in the hole. A bearing can also be provided in the hole, and the screw rod 9 is rotatably connected to the wall 2 through the bearing. The motor 7 is a servo motor 7, and the motor 7 and the reducer 8 are both fixed on the outer wall of the wall 2 provided with the inlet 3. A nut 13 adapted to the screw rod 9 is provided on the side wall of the connecting plate 2 6 away from the connecting plate 1 5, and the nut 13 is sleeved on the screw rod 9. A slot is provided on the side wall of the connecting plate 2 6, and a bearing is provided in the slot. The connecting rod of the nut 13 is inserted into the slot and rotatably connected to the connecting plate 2 6 through the bearing. The motor 7 drives the screw 9 to rotate through the reducer 8, and the nut 13 meshes with the screw 9. The forward and reverse rotation of the screw 9 is converted into the reciprocating linear motion of the nut 13. The nut 13 and the connecting plate 2 6 can only rotate, so the nut 13 drives the connecting plate 2 6 to move, and the connecting platform is unfolded or folded. When in use, the connecting platform is unfolded, and the entrance 3 of the elevator 1 can be directly reached to the entrance of the staircase 4 through the connecting platform, avoiding climbing.
