[0017] The effects provided in the invention content are only the effects of the embodiments, rather than all the effects of the present invention. The above technical solutions have the following advantages or beneficial effects:

[0018] 1. The car moves up and down in the elevator shaft formed by the limit frame. The bottom plate of the mounting frame and the stabilizing frame can play a stabilizing role for the car and the limit frame, providing a stable working environment for the lifting mechanism. During construction, the bottom plate can be fixed to the ground through expansion bolts, and then the installation of the elevator can be carried out. This elevator can be installed independently without relying on a supporting wall, with a fast construction speed, improving the applicable range of the elevator and having a great market competitive advantage.

[0019] 2. By setting the car door in the form of a three-fold door linkage, the space occupied by the elevator is reduced, and a transmission mechanism with a delicate structure is adopted, with low manufacturing cost and low failure rate. After the door is closed, the inner door panel contacts the first stop block, and the middle door panel contacts the second stop block. The first stop block and the second stop block can fix the inner door panel and the middle door panel, improving the stability of the car door.

[0020] 3. When the car reaches the designated floor, the car door faces the landing door of that floor. During the movement of the car, the guide wheel will gradually insert into the card slot of the linkage plate on the landing door of that floor. When the car door opens and closes, it will drive the landing door to open and close, simplifying the transmission mechanism and saving costs.

[0021] 4. During the working process, if there is an offset, the alignment plate can align the guide wheel into the U-shaped card slot, improving the stability of the equipment. Description of the Drawings

[0043] As Figure 6 ,Figure 12 , Figure 14 As shown in Figure 14 , the door opening mechanism 38 includes a motor 381, a first transmission belt 382, a second connecting plate 383, a first connecting plate 384, and a third pulley 386. One third pulley 386 is vertically arranged at each end of the top surface of the first guide rail plate 324 facing the direction of the landing door 30. A rotating shaft is arranged at the center of the third pulley 386. The third pulley 386 is installed on the first guide rail plate 324 through a bearing seat. The motor 381 is fixed on the first guide rail plate 324. The output shaft of the motor 381 is connected to the rotating shaft of one of the third pulleys 386. The first transmission belt 382 connects the two third pulleys 386. The lower end of the first connecting plate 384 is connected to the top surface of the left outer door panel 321. The upper end of the first connecting plate 384 sequentially passes through the first guide rail plate 324 and the top surface of the car 33 and then is connected to the lower end of the first transmission belt 382. The lower end of the second connecting plate 383 is connected to the top surface of the right outer door panel 321. The upper end of the second connecting plate 383 sequentially passes through the first guide rail plate 324 and the top surface of the car 33 and then is connected to the upper end of the first transmission belt 382. The door opening mechanism 38 further includes a guide pulley 385 and a linkage plate 387. The linkage plate 387 is installed inside the inner layer plate 303. The linkage plate 387 is vertically provided with an open U-shaped card slot facing the car 33. Guide pulleys 385 corresponding to the U-shaped card slot are arranged on the side of the first connecting plate 384 and the second connecting plate 383 facing the outside of the car 33. Two guide pulleys 385 are horizontally arranged on each linkage plate 387. The guide pulleys 385 are vertically arranged facing the landing door 30. A horizontal rotating shaft is arranged at the center of the guide pulley 385. The rotating shaft is connected to the first connecting plate 384 or the second connecting plate 383. The guide pulley 385 is arranged directly above or directly below the card slot. The outer distance between the two guide pulleys 385 is equal to the width of the card slot. When the car 33 reaches the designated floor, the car door 32 is directly opposite the landing door 30 of this floor. During the movement of the car 33, the guide pulley 385 will gradually insert into the card slot of the linkage plate 387 on the landing door 30 of this floor. When the car door 32 opens and closes, it will drive the landing door 30 to open and close at the same time, simplifying the transmission mechanism and saving costs. The U-shaped card slot on the linkage plate 387 is located in the gap between the inner layer plate 303 and the car door 32. Guide plates opening outward are respectively arranged at the top and bottom openings of the U-shaped card slot. During the working process, if there is an offset, the guide plate can guide the guide pulley 385 into the U-shaped card slot, improving the stability of the equipment.

[0044] The rotation of the motor 381 drives the rotation of the first drive belt 382, thereby driving the relative movement of the outer door panels 321 on both sides. By adjusting the rotation direction of the motor 381, the opening and closing of the car door 32 can be achieved. When the car door 32 is fully opened, the outer door panels 321, the middle door panel 322, and the inner door panel 323 completely overlap and are located outside the opening of the car 33. When closing the car door 32, first start the motor 381 to drive the outer door panel 321 to move towards the middle of the opening of the car 33. At the beginning, only the outer door panel 321 moves. When the convex block on the outer door panel 321 slides to the side of the groove on the middle door panel 322 close to the center of the car 33, the outer door panel 321 drives the middle door panel 322 to move together. When the convex block on the middle door panel 322 slides to the side of the groove on the inner door panel 323 close to the center of the car 33, the middle door panel 322 drives the inner door panel 323 to move together until the outer door panels 321 on both sides are in contact, completing the door closing. After the door closing is completed, the inner door panel 323 contacts the first stop 325, and the middle door panel 322 contacts the second stop 327. The first stop 325 and the second stop 327 can fix the inner door panel 323 and the middle door panel 322, improving the stability of the car door 32. By setting the car door 32 in the form of a three-fold door linkage, the space occupied by the elevator is reduced, and a transmission mechanism with a delicate structure is adopted, with low manufacturing cost and low failure rate.
