[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. 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

[0024] Refer to Figure 1 、 Figure 2, An embodiment provided by the present utility model: A three-axis elevator facilitating self-locking, including two fixed frames 8. Two uniformly distributed guide rails 9 are fixedly connected to the top side of the middle part of the fixed frame 8. A second threaded rod 10 is rotatably connected to the middle part of the fixed frame 8. One end of the second threaded rod 10 penetrates through the fixed frame 8, and a handwheel 7 is fixedly connected to one end of the second threaded rod 10. One of the fixed frames 8 is slidably connected to the top side of the other fixed frame 8. One of the second threaded rods 10 is threadedly connected to the inner side of the bottom of one of the fixed frames 8. An installation frame 2 is slidably connected to the top side of one of the fixed frames 8. A moving block 27 is slidably connected inside the installation frame 2. A load platform 4 is fixedly connected to the top of the front side of the moving block 27. Two support frames 5 are fixedly connected to the front side of the moving block 27. The top sides of the support frames 5 are fixedly connected to the bottom side of the load platform 4. An electric push rod 14 is fixedly connected inside the load platform 4. Rotating rods 15 are rotatably connected to both the left and right sides of the telescopic end of the electric push rod 14. One end of the rotating rod 15 is rotatably connected to a connecting plate 16. Two sliders 13 are fixedly connected to the bottom side of the connecting plate 16. A plurality of uniformly distributed sliding grooves are formed inside the load platform 4. The sliders 13 are slidably connected inside the sliding grooves. Two mounting rods 12 are fixedly connected to the top side of the connecting plate 16. A support rod 17 is slidably connected inside the mounting rod 12. Clamping plates 11 are fixedly connected to the top sides of adjacent support rods 17.

[0025] Specifically, the fixed frame 8 is used to support the movement of the installation frame 2. The guide rail 9 can limit the movement of one of the fixed frames 8 and the installation frame 2. Rotating the handwheel 7 can drive the rotation of the second threaded rod 10, thereby driving the movement of one of the fixed frames 8 and the installation frame 2. The installation frame 2 plays a role in supporting the movement of the moving block 27. The moving block 27 is used to install the load platform 4 and the support frames 5. The support frames 5 can support the load platform 4 and increase the stability of the load platform 4. Materials can be placed on the surface of the load platform 4 for transportation. When the telescopic end of the electric push rod 14 extends and retracts, it can drive the rotation of the rotating rod 15. The rotation of the rotating rod 15 can drive the movement of the connecting plate 16. The sliding of the sliders 13 inside the sliding grooves can limit the movement of the connecting plate 16. The mounting rods 12 and the support rods 17 are used to install and fix the clamping plates 11. The clamping plates 11 can clamp and fix the materials, fixing the materials on the surface of the load platform 4.

[0026] Referring to Figure 1 , Figure 4 , a locking component is arranged inside the fixed frame 8. Both of the two locking components include a gear 24. The gear 24 is fixedly connected to the outer circumference of the second threaded rod 10. The gear 24 is arranged inside the fixed frame 8. A connecting rod 21 is rotatably connected to the inside of the fixed frame 8. A stopper 25 is fixedly connected to the top side of the connecting rod 21. One end of the stopper 25 abuts against the gear 24. A moving rod 6 is fixedly connected to the bottom of the connecting rod 21. The moving rod 6 is slidably connected to the inside of the fixed frame 8. Mounting frames 22 are fixedly connected to both the inside of the fixed frame 8 and one side of the connecting rod 21. A second spring 23 is arranged inside the fixed frame 8. The upper and lower ends of the second spring 23 are respectively fixedly connected to the outer circumferences of the two mounting frames 22.

[0027] Specifically, the connecting rod 21 is used to install the stopper 25 and drive the stopper 25 to move. After the stopper 25 abuts against the inside of the gear 24, it can block the continuous rotation of the second threaded rod 10. Pushing the moving rod 6 can drive the connecting rod 21 to rotate. The mounting bracket 22 is used to install the second spring 23, and the second spring 23 can pull the connecting rod 21 to rotate so that the stopper 25 contacts the gear 24.

[0028] Refer to Figure 1 , a motor 1 is fixedly connected to the top side of the mounting frame 2. The driving end of the motor 1 is fixedly connected to a first threaded rod 3. The first threaded rod 3 is threadedly connected to the inside of the left side of the moving block 27. A guide rod 26 is fixedly connected inside the mounting frame 2, and the guide rod 26 is slidably connected to the inside of the right side of the moving block 27.

[0029] Specifically, the motor 1 is used to drive the first threaded rod 3 to rotate. The rotation of the first threaded rod 3 can drive the moving block 27 to move up and down. The guide rod 26 is used to limit the movement of the moving block 27.

[0030] Refer to Figures 1-3 , a limiting block 20 is fixedly connected to the bottom side of the support rod 17. The limiting block 20 is slidably connected to the inside of the mounting rod 12. Two convex blocks 18 are slidably connected to the inside of the limiting block 20. One side of the convex block 18 is fixedly connected to a first spring 19. One end of the first spring 19 is fixedly connected to the inside of the limiting block 20. A plurality of uniformly distributed grooves are formed inside the mounting rod 12, and the convex block 18 is slidably connected to the inside of the groove.

[0031] Specifically, the support rod 17 can slide inside the mounting rod 12 to adjust the height of the clamping plate 11. The limiting block 20 can limit the movement of the support rod 17 to prevent the support rod 17 from falling off the inside of the mounting rod 12. The convex block 18 can be pushed by the first spring 19 so that one end is inserted into the inside of the groove, thereby fixing the height of the support rod 17.

[0032] Working principle: When transporting materials, place the materials on the top side of the loading platform 4. Then, pull the clamping plate 11 to move so that the height of the clamping plate 11 adapts to the size of the materials. The convex block 18 inside the limit block 20 is pushed by the first spring 19 and inserted into the groove to fix the height of the clamping plate 11. After that, start the electric push rod 14. The telescopic end of the electric push rod 14 extends to drive the two rotating rods 15 to rotate. The two rotating rods 15 rotate to drive the two connecting plates 16 to drive the two clamping plates 11 to move towards each other respectively, so that the two clamping plates 11 clamp and fix the materials to prevent the materials from shifting during transportation. After fixing the materials on the top side of the loading platform 4, start the motor 1. The motor 1 drives the first threaded rod 3 to rotate, thereby driving the moving block 27 and the loading platform 4 to move up and down. When the loading platform 4 moves to the appropriate position, press the moving rod 6 to drive the connecting rod 21 to rotate. The connecting rod 21 rotates to separate the stop block 25 from the gear 25, so that the stop block 24 no longer restricts the rotation of the gear 24. Then, the two handwheels 7 can be rotated. The two handwheels 7 drive the two second threaded rods 10 to rotate respectively. The two second threaded rods 10 rotate to drive one of the fixed frames 8 and the mounting frame 2 to move respectively, so as to adjust the position of the loading platform 4. When the position adjustment of the loading platform 4 is completed, the second spring 23 can pull the connecting rod 21 to rotate. The connecting rod 21 rotates to drive the stop block 25 to move and make the stop block 25 contact with the gear 24 to block the second threaded rod 10 from continuing to rotate, so as to maintain the stability of the loading platform 4.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
