[0029] Reference Figure 1 The mounting structure 2 includes a first limiting rod 21 located on both sides of the frame body 1 and a driving member for driving the two first limiting rods 21 to slide in a direction away from or close to each other. A first sliding groove is opened on both sides of the frame body 1, and the length direction of the first sliding groove is parallel to the width direction of the frame body 1. The cross-section of the first limiting rod 21 is rectangular, and the first limiting rod 21 is slidably connected to the first sliding groove.
[0030] Reference Figure 1The first limiting rods 21 have a threaded portion at one end close to each other, the driving member is a sleeve rod 22, the sleeve rod 22 has a threaded hole inside, the threaded portion of the first limiting rod 21 is threadedly connected to the sleeve rod 22, and the threaded portions of the two first limiting rods 21 have opposite directions of rotation. By rotating the sleeve rod 22, the two first limiting rods 21 can slide in a direction away from each other, so that the distance between the ends of the two first limiting rods 21 away from each other is greater than the distance of the elevator door, so that the first limiting rods 21 abut against the cavity walls on both sides of the elevator door, thereby limiting the frame 1.
[0031] Reference Figure 1 A second limiting rod 23 is fixedly connected above the first limiting rod 21, and the second limiting rod 23 is set in an L shape. The first limiting rod 21 and the second limiting rod 23 are fixedly connected to a plurality of abutment blocks 24 near the side wall of the elevator shaft, and the plurality of abutment blocks 24 are distributed along the width direction of the frame 1, and the abutment blocks 24 are elastically set.
[0032] Reference Figure 1 The abutment block 24 is conical, and a conical adsorption chamber 241 is provided on the side of the abutment block 24 close to the elevator shaft. When the abutment block 24 abuts against the walls on both sides of the elevator door, the air in the adsorption chamber 241 is squeezed out, so that the abutment block 24 abuts against the walls on both sides of the elevator door, thereby improving the limiting stability of the first limiting rod 21 and the second limiting rod 23.
[0033] Reference Figure 1 A support rod 3 is fixedly connected to one side of the frame 1 near the elevator entrance. Two support rods 3 are provided.
