It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0035] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] First, the X direction, Y direction and Z direction mentioned in the embodiment of the present application can be referred to in the attached drawings. Figure 1 and Figure 3 The marked directions. Among them, the X direction, Y direction and Z direction intersect each other.

[0038] like Figures 1-6 As shown, according to the first aspect of an embodiment of the present application, a lifting device is provided, including a driving mechanism 1, a first connecting member 2 and a second connecting member 3; the driving mechanism 1 includes a first synchronous wheel assembly 11, a second synchronous wheel assembly 12 and a synchronous belt 13, the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12 are spaced apart along the X direction, and the synchronous belt 13 is sleeved on the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12; the first connecting member 2 is rotatably connected to the first synchronous wheel assembly 11, and the first connecting member 2 can move relative to the first synchronous wheel assembly 11 along the Z direction; the second connecting member 3 is rotatably connected to the second synchronous wheel assembly 12, and the second connecting member 3 can move relative to the second synchronous wheel assembly 12 along the Z direction.

[0039] like Figures 1-4 As shown, the lifting device includes a driving mechanism 1 , a first connecting member 2 and a second connecting member 3 .

[0040] Among them, the driving mechanism 1 includes a first synchronous wheel assembly 11, a second synchronous wheel assembly 12 and a synchronous belt 13. The first synchronous wheel assembly 11 and the second synchronous wheel assembly 12 are arranged at intervals in the X direction, and an accommodating space is formed between the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12; the synchronous belt 13 is sleeved on the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12. When the synchronous belt 13 rotates, it will drive the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12 to rotate around their own axes, that is, around the axis in the Z direction.

[0041] The first connecting member 2 is rotationally connected to the first synchronous wheel assembly 11. When the first synchronous wheel assembly 11 rotates around the axis of the Z direction, the first connecting member 2 will move along the Z direction relative to the first synchronous wheel assembly 11; the second connecting member 3 is rotationally connected to the second synchronous wheel assembly 12. When the second synchronous wheel assembly 12 rotates around the axis of the Z direction, the second connecting member 3 will move along the Z direction relative to the second synchronous wheel assembly 12.

[0042] To further illustrate, the first connecting member 2 and the second connecting member 3 can be connected to both ends of the mesh plate 8. When the first connecting member 2 and the second connecting member 3 move in the Z direction, the mesh plate 8 will move in the Z direction along with the first connecting member 2 and the second connecting member 3. Since the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12 rotate via the synchronous belt 13, the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12 rotate synchronously, so the first connecting member 2 and the second connecting member 3 also move synchronously. Therefore, the two ends of the mesh plate 8 moved by the first connecting member 2 and the second connecting member 3 also move synchronously, thereby preventing the mesh plate 8 from being skewed.

[0043] In an optional embodiment, the first synchronous wheel assembly 11 includes a first synchronous wheel 111 and a first screw 112, the first screw 112 is connected to the first synchronous wheel 111, the first connecting member 2 is rotatably connected to the first screw 112, and the first connecting member 2 can move along the Z direction relative to the first screw 112;

[0044] The second synchronous wheel assembly 12 includes a second synchronous wheel 121 and a second screw 122, the second screw 122 is connected to the second synchronous wheel 121, the second connecting member 3 is rotatably connected to the second screw 122, and the second connecting member 3 can move along the Z direction relative to the second screw 122; the synchronous belt 13 is sleeved on the first synchronous wheel 111 and the second synchronous wheel 121.

[0045] like Figure 1 and Figure 2As shown, the first synchronous wheel assembly 11 includes a first synchronous wheel 111 and a first screw 112, wherein the first screw 112 is connected to the first synchronous wheel 111, the axis of the first screw 112 coincides with the axis of the first synchronous wheel 111, the axis direction of the first screw 112 and the axis direction of the first synchronous wheel 111 are the same as the Z direction, and the first connecting member 2 is rotationally connected to the first screw 112. Therefore, when the first synchronous wheel 111 rotates about the Z direction, the first screw 112 will also rotate accordingly, and the first connecting member 2 will move along the Z direction relative to the first screw 112. The second synchronous wheel assembly 12 includes a second synchronous wheel 121 and a second screw 122, wherein the second screw 122 is connected to the second synchronous wheel 121, the axis of the second screw 122 coincides with the axis of the second synchronous wheel 121, the axial direction of the second screw 122 and the axial direction of the first synchronous wheel 111 are the same as the Z direction, and the second connecting member 3 is rotatably connected to the second screw 122. Therefore, when the second synchronous wheel 121 rotates about the Z direction, the second screw 122 will also rotate accordingly, and the second connecting member 3 will move along the Z direction relative to the second screw 122.

[0046] To further illustrate, the synchronous belt 13 is sleeved on the first synchronous wheel 111 and the second synchronous wheel 121, so when the synchronous belt 13 rotates, the first synchronous wheel 111 and the second synchronous wheel 121 will rotate at the same time; the first synchronous wheel assembly 11 and the second synchronous wheel assembly 12 in this embodiment have a simple structure, are easy to install, and have a good synchronization effect.

[0049] like Figure 1 and Figure 2As shown, the drive mechanism 1 also includes a drive assembly 14 and a driving wheel 15.

The driving wheel 15 and the second synchronous wheel 121 can be arranged sequentially along the X direction, or can be arranged between the first synchronous wheel 111 and the second synchronous wheel 121 in the X direction. The synchronous belt 13 is sleeved on the driving wheel 15, the first synchronous wheel 111 and the second synchronous wheel 121. The driving end of the drive assembly 14 is connected to the driving wheel 15. Therefore, when the drive assembly 14 drives the driving wheel 15 to rotate, it will drive the synchronous belt 13 to rotate, and at the same time, the first synchronous wheel 111 and the second synchronous wheel 121 will also rotate accordingly. By providing the driving wheel 15, the drive mechanism 1 does not need to install the lead screw and the drive assembly 14 on the first synchronous wheel 111 or the second synchronous wheel 121 at the same time, which can simplify the installation structure.
