[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] See also Figures 1-6 A construction material lifting platform includes a base plate 1, a bearing plate 2 and a scissors frame 3. The upper surface of the base plate 1 is connected to two support seats 4, and the two support seats 4 are symmetrical. The inner wall of the support seat 4 is rotatably connected to a screw rod 5, which provides supporting force for the screw rod 5 through the support seat 4 to maintain the stability of the screw rod 5 during rotation. The outer surface of the screw rod 5 is connected to a threaded seat 6, and the outer surface of the threaded seat 6 is connected to a connecting rod 7. The connecting rod 7 is rotatably connected to one end of the scissors frame 3, and a driving force is generated by the rotation of the screw rod 5 to push the threaded seat 6 to move its position. When the threaded seat 6 moves its position, the scissors frame 3 is driven to retract through the connecting rod 7, providing power for the retraction of the scissors frame 3.

[0024] A first snap ring 8 is connected to one side of one of the support seats 4, and a second snap ring 9 is slidably connected to the outer surface of the screw rod 5. The second snap ring 9 is in contact with the first snap ring 8, and the first snap ring 8 provides support force for the second snap ring 9. After the second snap ring 9 contacts the first snap ring 8, the rotation of the second snap ring 9 is restricted.

[0025] A spring 10 is sleeved on the outside of the screw rod 5, one end of the spring 10 is connected to one side of the second retaining ring 9, and the other end of the spring 10 is connected to one side of the support sleeve 13. The spring 10 provides elastic driving force to push the second retaining ring 9 to tightly contact the first retaining ring 8. At the same time, the spring 10 provides reset power after the second retaining ring 9 is separated from the first retaining ring 8.

[0026] The outer surface of the second snap ring 9 is connected to a support plate 11, and the outer surface of the support plate 11 is connected to a relay rod 12. The second snap ring 9 receives the driving force of the heart-shaped groove 18 through the relay rod 12. One end of the screw rod 5 is connected to a support sleeve 13, and a slide groove 14 is provided on the inner side of the support sleeve 13. The outer surface of the support sleeve 13 is rotatably connected to a handwheel 15, and the inner wall of the handwheel 15 is connected to a stopper 16, and the stopper 16 is located inside the slide groove 14. The stability of the handwheel 15 during rotation is maintained by the support sleeve 13, and the handwheel 15 outputs power through the stopper 16, and the support sleeve 13 receives the power output by the stopper 16 through the slide groove 14. The opening of the slide groove 14 is larger than the stopper 16. When the handwheel 15 drives the stopper 16 to rotate, there will be a period of idle period. The stopper 16 moves to contact one end of the slide groove 14 before it can drive the screw rod 5 to rotate.

[0027] A heart-shaped plate 17 is connected to one side of the handwheel 15, and a heart-shaped groove 18 is provided on the inner side of the heart-shaped plate 17. The heart-shaped groove 18 is similar to a triangle, and there is an inclination angle between the heart-shaped groove 18 and the relay pole 12. The inner wall of the heart-shaped groove 18 is slidably connected to the outer surface of the relay pole 12. When the handwheel 15 rotates during the idle period, the heart-shaped plate 17 is driven to move its position. The heart-shaped plate 17 drives the relay pole 12 to move its position through the heart-shaped groove 18, and the relay pole 12 drives the second retaining ring 9 to disengage from contact with the first retaining ring 8 through the support plate 11.

[0028] A positioning groove 19 is provided on the inner side of the screw rod 5, and a positioning block 20 is connected to the inner wall of the second retaining ring 9. The outer surface of the positioning block 20 is slidingly connected to the inner wall of the positioning groove 19. The positioning groove 19 guides the moving direction of the positioning block 20 to maintain the stability of the positioning block 20. The positioning block 20 provides support force for the second retaining ring 9 to improve the stability of the second retaining ring 9.

[0029] Two slides 21 are connected to the upper surface of the base plate 1, and the two slides 21 are symmetrical. There are two scissor frames 3, and the two scissor frames 3 are symmetrical. The driving force is generated by the contraction of the scissor frames 3, and the stability of the first slide 23 when it is in the moving position is maintained by the slide 21. The bottom ends of the two scissor frames 3 are rotatably connected with the first base 22 and the first slide 23. The first base 22 is connected to the upper surface of the base plate 1, and the first slide 23 is slidably connected to the inner wall of the slide 21. The first base 22 provides support for the scissor frames 3 to maintain the stability of the scissor frames 3, and the scissor frames 3 are driven to contract by moving the position of the first slide 23.

[0030] The top of the scissors frame 3 is connected to a second base 24 and a second slide 25. The second base 24 is connected to the lower surface of the carrying plate 2. The driving force of the scissors frame 3 is transmitted to the carrying plate 2 through the second slide 25 and the second base 24, driving the carrying plate 2 to rise and fall. The lower surface of the carrying plate 2 is connected to a slide 26. The outer surface of the slide 26 is slidably connected to the inner wall of the second slide 25. The second slide 25 is supported by the slide 26 to maintain the stability of the second slide 25 when it is in the moving position. The angle difference generated by the scissors frame 3 when it is retracted is compensated by the slide 26.

[0031] When the utility model is in use: first, the hand wheel 15 is rotated. When the hand wheel 15 rotates, the stopper 16 and the heart-shaped plate 17 are moved at the same time. When the heart-shaped plate 17 moves, the relay rod 12 is driven to move through the heart-shaped groove 18. The relay rod 12 drives the support plate 11 to move. The support plate 11 drives the second snap ring 9 to move. After the second snap ring 9 moves, it disengages from the contact with the first snap ring 8. The second snap ring 9 moves and the spring 10 is compressed. At the same time, the stopper 16 contacts one end of the slide groove 14. After the stopper 16 contacts the slide groove 14, the hand wheel 15 can output power to the support sleeve 13. The support sleeve 13 drives the screw rod 5 to rotate. After the hand wheel 15 stops rotating, the spring 10 pushes the second snap ring 9 to contact the first snap ring 8, forming a mutual dislocation blockage, thereby limiting the rotation of the screw rod 5.
