[0029] It should be noted that the outer lower side of the base frame 1 is mounted on the inner wall of the elevator shaft, and a plurality of screw holes are provided on the mounting beam 4 for mounting the elevator host.

[0030] like Figure 3 , Figure 4 As shown, the fixing mechanism 3 includes a fixing beam 31, the front and rear ends of the mounting beam 4 are fixedly connected to the left and right sides of the side where the fixing beam 31 is close to each other, the outer wall of the fixing beam 31 is movably sleeved on the inner side of the placement groove 2 near the bottom, and the left and right sides of the base frame 1 are fixedly connected to the upper side with a clamping plate 32, and the upper sides of the two clamping plates 32 are overlapped with fixing frames 33, and the interiors of the front and rear sides of the two fixing frames 33 are threadedly connected with two screws 34 symmetrically distributed front and back, and the outer wall of the screw 34 is threadedly connected to the inner side of the left and right walls of the base frame 1 near the bottom.

[0031] It should be noted that the bottoms of the front and rear sides of the fixing frame 33 are movably sleeved in grooves opened near the four corners of the upper surface of the base frame 1, and the screws 34 are used to fix the fixing frame 33 on the base frame 1, so that the fixing beam 31 cannot be taken out.

[0032] like Figure 3 , Figure 5 As shown, a first bevel gear 35 is rotatably connected to the middle part of the inner upper surface of the fixed beam 31, and two left-right symmetrical fixing components 38 are movably sleeved on the inner side of the fixed beam 31 near the left and right sides. A screw rod 36 is threadedly connected to the inner side of the fixing component 38, and a second bevel gear 37 is fixedly connected to the outer wall of the screw rod 36 near the middle part, and the upper side of the second bevel gear 37 is meshed and connected with the left side of the screw rod 36.

[0033] It should be noted that the screw rod 36 is a bidirectional screw rod having two threads in opposite directions. The two fixing components 38 are threadedly connected to different threads respectively. Rotating the first bevel gear 35 causes the first bevel gear 35 to drive the second bevel gear 37 to rotate. When the second bevel gear 37 rotates, it drives the screw rod 36 to rotate. When the screw rod 36 rotates, the two fixing components 38 make opposite movements in the left and right directions.

[0034] like Figure 3 , Figure 4 As shown, the fixing assembly 38 includes a movable sleeve 381, the outer wall of the movable sleeve 381 is movably sleeved on the inner side of the fixed beam 31, the inner side of the movable sleeve 381 is threadedly connected to the outer wall of the screw rod 36, the outer wall of the movable sleeve 381 is movably sleeved with a rubber sleeve 382, ​​a movable sleeve 383 is movably sleeved in a mounting groove opened on the side of the movable sleeve 381 away from the first bevel gear 35, a first spring 384 is fixedly connected to the inner side of the movable sleeve 383 away from the first bevel gear 35, and the left and right sides of the fixed beam 31 are fixedly connected with first rubber pads 310.

[0035] It should be noted that the first rubber pad 310 is used to provide redundant space when the fixed beam 31 moves left and right. The outer wall of the movable sleeve 381 is movably sleeved on the inner sides of the left and right walls of the base frame 1 on the side away from the first bevel gear 35. The first spring 384 contains a damping mechanism. When the elevator main unit is vibrated and drives the fixed beam 31 to move left and right, the first spring 384 pushes the movable sleeve 383 and then pushes the movable sleeve 381 in the opposite direction to offset the lateral force.

[0036] like Figure 3 , Figure 5As shown, a limiting component 39 is fixedly connected to the middle part of the upper surface of the fixed beam 31, and the limiting component 39 includes a first fixed sleeve 391, the lower side of the first fixed sleeve 391 is fixedly connected to the middle part of the upper surface of the fixed beam 31, the inner side of the first fixed sleeve 391 is movably sleeved with a limiting sleeve 393, the inner side of the first fixed sleeve 391 is movably sleeved with a second spring 392, and the second spring 392 is located on the lower side of the limiting sleeve 393, and the upper side axis of the first bevel gear 35 is fixedly connected with a special-shaped block 394 through a round rod, and the outer side of the special-shaped block 394 is movably sleeved on the inner side of the limiting sleeve 393.

[0037] It should be noted that when the special-shaped block 394 is located inside the limiting sleeve 393, the first bevel gear 35 cannot be rotated, and the limiting sleeve 393 is pressed downward, so that the special-shaped block 394 is separated from the limiting sleeve 393, so that the first bevel gear 35 can rotate.

[0038] like Figure 1 , Figure 6 and Figure 7 As shown, the shielding mechanism 6 includes an isolation cover 61, and four rectangularly distributed mounting holes 62 are provided on the lower surface of the isolation cover 61 near the four corners, and the inner sides of the four mounting holes 62 are movably sleeved with mounting components 64, and the mounting components 64 include a second fixed sleeve 641, and the outer wall of the second fixed sleeve 641 is movably sleeved on the inner side of the mounting hole 62, and the lower end of the second fixed sleeve 641 is fixedly connected to the upper surface of the base frame 1 near the four corners, and the inner side of the second fixed sleeve 641 is movably sleeved with a circular plate 642, and the outer wall of the circular plate 642 is fixedly connected to the mounting sleeve 643 through a connecting block, and the outer wall of the mounting sleeve 643 is rotatably connected to a rotating sleeve 644, and the inner walls of the four mounting holes 62 are provided with placement grooves 63 near the left and right sides.

[0039] It should be noted that two annularly distributed protrusions are fixedly connected to the outer wall of the rotating sleeve 644. When the protrusions are aligned with the placement grooves 63, the rotating sleeve 644 can be movably sleeved on the inner side of the mounting hole 62, otherwise it cannot.

[0040] like Figure 7 As shown, the inner wall of the second fixing sleeve 641 is movably sleeved with a third spring 645 , and the third spring 645 is located on the upper side of the circular plate 642 , and the inner walls of the four mounting holes 62 are provided with limiting grooves 65 at the front and rear sides near the upper side.

[0041] It should be noted that the rotating sleeve 644 is pulled upward and then rotated to align the protrusion on the rotating sleeve 644 with the limiting groove 65, and then released so that the third spring 645 pushes the protrusion on the rotating sleeve 644 to the inside of the limiting groove 65, so that the isolation cover 61 is fixed.

[0042] like Figure 7 As shown, the outer wall of the rotating sleeve 644 is provided with friction patterns.

[0043] It should be noted that the friction pattern is used to increase the friction force of the hand on the rotating sleeve 644, making it easier to pull or rotate the rotating sleeve 644.

[0044] The working principle of the utility model is as follows: first, the outer wall of the rotating sleeve 644 is fixedly connected with two annularly distributed protrusions. When the protrusions are aligned with the placement grooves 63, the rotating sleeve 644 can be movably sleeved on the inner side of the mounting hole 62, otherwise it cannot be pulled upward, and then the rotating sleeve 644 is rotated, and the protrusions on the rotating sleeve 644 are aligned with the limiting grooves 65, and then the third spring 645 is released to push the protrusions on the rotating sleeve 644 to the inner side of the limiting grooves 65, so that the isolation cover 61 is fixed, and the isolation cover 61 is fixed by aligning the placement grooves 63 with the protrusions on the rotating sleeve 644. It is installed on the outside of the second fixed sleeve 641, and then the protrusion on the rotating sleeve 644 is movably sleeved into the inner side of the limiting groove 65, so that the isolation cover 61 is fixed. It is easy to install, simple to operate, quick to disassemble, and easy to maintain. Finally, the bottom of the front and rear sides of the fixing frame 33 are movably sleeved in the grooves opened near the four corners of the upper surface of the base frame 1. The screw 34 is used to fix the fixing frame 33 on the base frame 1, so that the fixed beam 31 cannot be taken out. The screw 36 is a bidirectional screw with two threads in opposite directions. The two fixing components 38 are respectively threadedly connected with different threads. The first bevel gear 35 is rotated so that the first bevel gear 35 drives the second bevel gear 37 to rotate. When the second bevel gear 37 rotates, the screw rod 36 is driven to rotate. When the screw rod 36 rotates, the two fixed components 38 make opposite movements in the left and right directions. The first rubber pad 310 is used to provide redundant space when the fixed beam 31 moves left and right. The outer wall of the movable sleeve 381 is away from the side of the first bevel gear 35 and is movably sleeved on the inner sides of the left and right walls of the base frame 1. The first spring 384 contains a damping mechanism. When the elevator host is vibrated and drives the fixed beam 31 to move left and right, the first spring 384 pushes the movable sleeve 383 Then, the movable sleeve 381 is pushed in the reverse direction to offset the lateral force. When the special-shaped block 394 is located on the inner side of the limiting sleeve 393, the first bevel gear 35 cannot be rotated, and the limiting sleeve 393 is pressed downward, so that the special-shaped block 394 is separated from the limiting sleeve 393, so that the first bevel gear 35 can rotate. By installing the elevator main unit on the mounting beam 4, the second rubber pad 5 reduces the upper and lower side forces on the elevator main unit due to external vibration. The movable sleeve 383 is used to reduce the lateral force on the elevator main unit due to external vibration, so that the vibration of the elevator is offset, thereby increasing the service life of the elevator main unit.
