[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0024] This utility model provides a lifting platform that can solve the problem in related technologies where lifting platforms tend to sway and operate unstably when rising along the guide rails, posing certain safety risks.

[0025] See Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a lifting platform, comprising: a main frame 1, with a guide rail 2 installed along the height direction, the guide rail 2 including a base plate 21 fixed to the main frame 1 and a vertical plate 22 perpendicular to the base plate 21; a lifting platform 3, slidably mounted on the guide rail 2 via a roller mechanism 4, the roller mechanism 4 including a first roller 41 and a second roller 42, the wheel surfaces of the first roller 41 and the second roller 42 respectively clamping the two sides of the plate surface of the vertical plate 22; and a drive mechanism 9, mounted on the main frame 1 and connected to the lifting platform 3. In this embodiment, by changing the traditional guide rail to a guide rail 2 with a base plate 21 and a vertical plate 22, and by setting two rollers to slide between the two sides of the vertical plate 22 respectively, the gap between the rollers and the guide rail is reduced, thereby reducing the shaking of the lifting platform, making the operation more stable, and reducing safety risks.

[0026] See Figure 1 and Figure 2 As shown, in some embodiments, the roller mechanism 4 further includes a third roller 43, the wheel surface of which abuts against the top surface of the vertical plate 22. In this embodiment, by setting the third roller 43, the axis of the third roller 43 is perpendicular to the axes of the first roller 41 and the second roller 42. The third roller 43 slides along the vertical plate 22, which can further reduce the gap between the roller mechanism and the guide rail 2 and increase the stability of the lifting platform.

[0027] See Figure 1 and Figure 2 As shown, in some embodiments, the roller mechanism 4 includes a first mounting plate 44 fixed to the lifting platform 3. The first mounting plate 44 has a U-shaped groove 45 in the center. The first roller 41 and the second roller 42 are respectively mounted on both sides of the U-shaped groove 45. In this embodiment, the surface of the first mounting plate 44 is parallel to the surface of the base plate 21. By setting the two rollers on both sides of the U-shaped groove 45, sufficient space is reserved for the vertical plate 22, avoiding interference between the roller mechanism 4 and the guide rail 2 during the sliding process, and ensuring the safety of the lifting process.

[0028] See Figure 1 and Figure 2 As shown, in some embodiments, a second mounting plate 46 is fixed to the inner side of the first mounting plate 44, and the surface of the second mounting plate 46 is parallel to the surface of the vertical plate 22. The third roller 43 is mounted on the second mounting plate 46. In this embodiment, by setting the second mounting plate 46, it is convenient to install the third roller 43 and make the wheel surface of the third roller 43 closely attached to the surface of the vertical plate 22.

[0029] See Figure 1 and Figure 2 As shown, in some embodiments, the U-shaped groove 45 is located above the vertical plate 22, and the third roller 43 extends out from the U-shaped groove 45. In this embodiment, the first roller 41 and the second roller 42 are sandwiched between opposite sides of the vertical plate 22, and the third roller 43 is located between the first roller 41 and the second roller 42, and extends out from the U-shaped groove 45 to abut against the top surface of the vertical plate 22. This can restrict the movement direction of the roller mechanism 4 on the guide rail 2 from all directions, and increase the stability of the lifting platform 3 when sliding.

[0030] See Figure 1 As shown, in some embodiments, a limiting plate 47 is fixed to the top of the first mounting plate 44. The surface of the limiting plate 47 is perpendicular to the surface of the vertical plate 22. The limiting plate 47 is provided with a limiting groove 48, and the vertical plate 22 is located in the limiting groove 48. In this embodiment, by setting the limiting plate 47, the limiting groove 48 can further restrict the movement path of the roller mechanism 4 along the guide rail 2, further reduce the shaking of the lifting platform 3, and make the operation more stable.

[0031] See Figure 1 As shown, in some embodiments, the guide rail 2 has a T-shaped cross-section, and the vertical plate 22 is located in the center of the base plate 21, resulting in uniform stress distribution, simple structure, and low cost. The guide rail 2 can also be L-shaped, cross-shaped, or other shapes.

[0032] See Figure 1 and Figure 2 As shown, in some embodiments, a mounting base 5 is fixed to the top of the limiting plate 47, and the mounting base 5 is fixed to the lifting platform 3. A pull rod 6 is mounted on the mounting base 5. In this embodiment, by setting the mounting base 5, the roller mechanism 4 can be fixed to the mounting base 5 after assembly, which is convenient to install and has high structural strength. The pull rod 6 is used for transmission connection with the drive mechanism 9 to provide driving force for the lifting platform 3.

[0033] See Figure 3As shown, in some embodiments, square supports 7 are provided on both sides of the lifting platform 3, and a roller mechanism 4 is installed at each of the four corners of the square supports 7. The installation of a roller mechanism 4 at each of the four corners of the square supports 7 increases the support of the lifting platform 3 and makes the lifting platform 3 more stable.

[0034] As shown in Figure 3, in some embodiments, a protective net 8 is installed on the outer side of the main frame 1 to provide protection and improve safety during operation.
