Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Figure 1 It shows a schematic structural diagram of the elevator plumb line positioning mechanism in the embodiment of the present utility model, Figure 2 It shows a schematic structural diagram of the locking component of the elevator plumb line positioning mechanism in the embodiment of the present utility model; the elevator plumb line positioning mechanism includes: a fixed base 1, a positioning plate 3 and a locking component. The top surface of the fixed base 1 is set as the placement area of the positioning plate 3, and one end of the positioning plate 3 extends outside the fixed base 1. Based on the end of the positioning plate 3 that extends outside the fixed base 1, the plumb line can be positioned. The calibrated position of the plumb line can be marked and positioned based on the positioning plate 3. When installing the next section of the guide rail, the plumb line can be quickly calibrated and positioned through the calibrated position of the plumb line marked by the positioning plate 3, and the accuracy of repeated calibration of the plumb line can be effectively improved.

[0028] The locking component includes: an action rod 21 rotatably arranged on the fixed base 1, an adjusting rod 22 arranged at one end of the action rod 21, and a suction cup 23 located on the adjusting rod 22. Based on the suction cup 23, the positioning plate 3 can be squeezed and fixed, so as to lock the position of the positioning plate 3.

[0029] The suction cup 23 is in contact with the top surface of the positioning plate 3. By rotating and adjusting the adjusting rod 22 to increase the extrusion pressure between the suction cup 23 and the positioning plate 3, the positioning plate 3 is pressed tightly against the top surface of the fixed base 1. By rotating the adjusting rod 22, the adjusting rod 22 moves downward, driving the suction cup 23 to squeeze the positioning plate 3 downward, thereby realizing the pressurized fixation of the positioning plate 3.

[0030] Further, based on the rotation of the adjusting rod 22, the extrusion pressure between the suction cup 23 and the positioning plate 3 is reduced, so that the positioning plate 3 moves on the top surface of the fixed base 1. By rotating the adjusting rod 22, the suction cup 23 of the adjusting rod 22 is separated from the positioning plate 3, and the operator can freely adjust the placement position of the positioning plate 3 on the top surface of the fixed base 1, so as to adjust the position of the positioning plate 3 according to the calibration position of the plumb line.

[0031] Specifically, the locking component further includes a rotating shaft 24. A fitting groove is provided on the fixed base 1. The rotating shaft 24 is rotatably arranged in the fitting groove. One end of the action rod 21 is fixed on the rotating shaft 24, and a spacing for accommodating the suction cup 23 and the positioning plate 3 is formed between the action rod 21 and the top surface of the fixed base 1. The action rod 21 is rotatably connected to the top surface of the fixed base 1 based on the rotating shaft 24. By rotating and adjusting the pose state of the action rod 21, the position of the suction cup 23 can be adjusted according to the position of the positioning plate 3.

[0032] Further, after the operator adjusts the position of the positioning plate 3 according to the plumb line calibration position, by rotating and adjusting the action rod 21, the suction cup 23 on the adjusting rod 22 can be attached to the positioning plate 3. By rotating the adjusting rod 22, the suction cup 23 is driven to adsorb and squeeze the positioning plate 3, so that the positioning plate 3 can be locked and fixed on the fixed base 1 based on the locking mechanism, and the action rod 21 can be locked on the fixed base 1 based on the pressing fit between the adjusting rod 22 and the positioning plate 3, thereby reducing the risk of the positioning plate 3 shifting.

[0033] Specifically, a threaded fitting hole is provided at the other end of the action rod 21. The adjusting rod 22 is inserted into the threaded fitting hole, and the adjusting rod 22 is in threaded fit connection with the threaded fitting hole of the action rod 21. The outer side wall of the adjusting rod 22 is provided with threads, so that the adjusting rod 22 can be screwed and fitted with the threaded fitting hole on the action rod 21. By rotating the adjusting rod 22, the position of the adjusting rod 22 can be adjusted in the vertical direction, so that the suction cup 23 of the adjusting rod 22 can squeeze and fix the positioning plate 3.

[0034] Further, one end of the adjusting rod 22 passes through the threaded fitting hole and is located below the action rod 21, and the suction cup 23 is arranged at one end of the adjusting rod 22. The suction cup 23 is fixed on the adjusting rod 22. When the adjusting rod 22 moves up and down in the vertical direction based on rotation, the suction cup 23 can move in the vertical direction along with the adjusting rod 22, realizing the pressing and fixing and releasing of the positioning plate 3.

[0035] Further, the other end of the adjusting rod 22 is bent to form a knob handle. The adjusting rod 22 can be integrally processed and formed, and the other end of the adjusting rod 22 is bent to form a knob handle, so that an operator can rotate and adjust the adjusting rod 22 to conveniently control the adsorption operation of the suction cup 23.

[0037] Further, a slot 32 is provided in the middle of the positioning plate 3. Based on the slot 32, the overall mass of the positioning plate 3 can be reduced, thereby improving the convenience of moving and position adjustment of the positioning plate 3.

[0040] Further, the connecting piece 41 can be made of a metal material, that is, the connecting piece 41 can be a metal sheet structure. Based on the metal sheet being wound to form a sleeve structure, the connection reliability between the positioning mechanism and the scaffold can be improved.

[0041] The connecting member 41 can also be made of plastic and is formed into a ring structure with a notch through integral molding, so that the connecting member 41 can be sleeved on the connecting rod of the scaffolding and locked on the connecting plate 42 by bolts or screws.
