[0039] In order to expand the application scope of the lifting device and improve the structural stability of the lifting device, an embodiment of the present invention provides a lifting device. In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail with reference to the following embodiments.

[0040] like Figures 1 to 3 As shown, the lifting device 1 provided in the embodiment of the present invention includes a base plate 2, a fixing portion 3, a support assembly 4, a driving device 7 and a controller (not shown in the figure) provided on the base plate 2, wherein:

[0041] The fixing portion 3 includes a first fixing unit 301 and a second fixing unit 302. The first fixing unit 301 includes a first fixing plate 3011 and a first linear guide 3012 vertically disposed on the first fixing plate 3011. The second fixing unit 302 includes a second fixing plate 3021 and a second linear guide 3022 vertically disposed on the second fixing plate 3021. The first fixing plate 3011 and the second fixing plate 3021 are disposed opposite each other.

[0042] The support assembly 4 includes a support portion 401 and a first slide groove (not shown) and a second slide groove (not shown) provided on the support portion 401. The first slide groove is slidably connected to the first linear guide rail 3012, and the second slide groove is slidably connected to the second linear guide rail 3022.

[0043] A driving device 7, used for driving the support portion 401 to move along the first linear guide rail 3012 and the second linear guide rail 3022;

[0044] The controller is connected to the driving device 7 and is used to control the driving device 7 to drive the support part 401 to move according to a set displacement.

[0045] To lift a component such as a water tank, the lifting device 1 employing this technical solution first places the water tank on the support portion 401. The controller then controls the drive device 7 to move the support portion 401 according to a set displacement. This allows for different lifting displacements to be set for different models of water tanks and other components, thereby expanding the applicability of the lifting device 1. Furthermore, because the support portion 401 is slidably connected to the fixing portion 3 via a slide groove and rails, the stability of the lifting device 1 is effectively improved.

[0046] like Figures 1 to 3 As shown, in any embodiment of the present technical solution, optionally, the support portion 401 includes a first support unit 4011 and a second support unit 4012 arranged relatively to each other, and the support assembly 4 also includes a connecting portion 402 for connecting the first support unit 4011 and the second support unit 4012; the first slide groove is arranged on the first support unit 4011, and the second slide groove is arranged on the second support unit 4012.

[0047] By configuring the support portion 401 as the first support unit 4011 and the second support unit 4012 , the structure of the lifting device 1 can be simplified.

[0048] like Figure 1 and Figure 2 As shown, in the embodiment of the present technical solution, optionally, the support portion 401 is provided between the first fixing plate 3011 and the second fixing plate 3021; the first fixing plate 3011 has a first strip-shaped hole 3013 provided in the vertical direction;

[0049] The lifting device 1 also includes a first adjustment component 5, which includes a first fixed block 501, a first L-shaped plate 502 and a first screw 503 arranged along the vertical direction, wherein: the first L-shaped plate 502 includes a first plate portion 5021 and a second plate portion 5022, the first plate portion 5021 is fixed to the first support unit 4011, and the second plate portion 5022 extends to the first strip hole 3013; the first fixed block 501 is arranged at the end of the first strip hole 3013 away from the bottom plate 2, and is fixed to the side of the first fixed plate 3011 away from the support portion 401; the first screw 503 is provided with a first stopper 5031 at one end close to the second plate portion 5022, and the other end passes through the first fixed block 501, and is fixed to the first fixed block 501 by two first adjustment nuts 5032 respectively provided on both sides of the first fixed block 501.

[0050] By providing the first adjustment assembly 5, before the lifting device 1 raises or lowers the enameled water tank and other components, the first adjustment nuts 5032 on both sides of the first fixing block 501 can be adjusted to adjust the vertical position of the first screw 503 relative to the first fixing block 501 as required. This in turn adjusts the relative position of the first stopper 5031 to the second plate 5022, thereby limiting the height to which the support portion 401 is raised. This effectively improves the accuracy of the height to which the lifting device 1 can be raised.

[0051] Further, such as Figure 1 and Figure 3 As shown, in any embodiment of the present technical solution, optionally, the second fixing plate 3021 has a second strip-shaped hole (not shown in the figure) arranged in the vertical direction;

[0052] The lifting device 1 also includes a second adjusting component 6, which includes a second fixed block 601, a second L-shaped plate 602 and a second screw 603 arranged along the vertical direction, wherein: the second L-shaped plate 602 includes a third plate portion 6021 and a fourth plate portion 6022, the third plate portion 6021 is fixed to the second support unit 4012, and the fourth plate portion 6022 extends to the second strip hole 3023; the second fixed block 601 is arranged at the end of the second strip hole 3023 away from the base plate 2, and is fixed to the side of the second fixed plate 3021 away from the support portion 401; the second screw 603 is provided with a second stop block 6031 at one end close to the fourth plate portion 6022, and the other end passes through the second fixed block 601, and is fixed to the second fixed block 601 by two second adjusting nuts 6032 respectively provided on both sides of the second fixed block 601.

[0053] In this way, the height to which the support portion 401 is raised can be limited by simultaneously adjusting the screws of the first adjustment component 5 and the second adjustment component 6. In addition, the simultaneous provision of the first adjustment component 5 and the second adjustment component 6 can further increase the structural stability of the lifting device 1.

[0054] like Figure 2 and Figure 3 As shown, in an embodiment of the present technical solution, optionally, the support portion 401 further includes a first support plate 4013 arranged at the top of the first support unit 4011 along the vertical direction, and a second support plate 4014 arranged at the top of the second support unit 4012 along the vertical direction, and the first support plate 4013 and the second support plate 4014 are arranged opposite to each other and have the same height.

[0055] By providing a support plate at the top end of the support portion 401 for supporting components, the structure of the lifting device 1 can be further simplified.

[0056] Further, such as Figure 2 and Figure 3 As shown, in the embodiment of the present technical solution, optionally, a first supporting platform 4015 is provided at one end of the first supporting unit 4011 close to the first supporting plate 4013, a first fixing structure 4016 is provided at one end of the first supporting plate 4013 close to the first supporting platform 4015, and the first fixing structure 4016 is fastened to the first supporting plate 4013; a second supporting platform 4017 is provided at one end of the second supporting unit 4012 close to the second supporting plate 4014, a second fixing structure 4018 is provided at one end of the second supporting plate 4014 close to the second supporting platform 4017, and the second fixing structure 4018 is fastened to the second supporting plate 4014.

[0057] By fastening the fixed structure to the support platform, the support plate can be replaced according to different needs, and the height position of the support plate can be fine-tuned by adding gaskets between the fixed structure and the support platform, thereby further expanding the scope of application of the lifting device 1.

[0058] like Figures 1 to 3 As shown, in any embodiment of the present technical solution, optionally, a first groove 4019 is provided at one end of the first support plate 4013 away from the first support unit 4011 , and a second groove 4020 is provided at one end of the second support plate 4014 away from the second support unit 4012 .

[0059] By setting a first groove 4019 at the end of the first support plate 4013 away from the first support unit 4011, and setting a second groove 4020 at the end of the second support plate 4014 away from the second support unit 4012, it is possible to facilitate the support plate to support components with a cylindrical outer contour such as enameled water tanks, and to improve the stability of the lifting device 1 during movement.

[0060] like Figure 1 As shown, in an embodiment of the present technical solution, optionally, the connecting portion 402 is a horizontally arranged connecting plate, and the connecting plate is provided with a through hole 4021 for the driving end of the driving device 7 to extend out. The support assembly 4 also includes a third support unit 403 arranged on the side of the connecting plate close to the first support plate 4013, and the driving end is driven and connected to the third support unit 403.

[0061] By providing the third support unit 403 , not only the support stability of the supported component can be increased, but also the driving stability of the driving device 7 on the support portion 401 can be improved because the driving end of the driving device 7 is drivingly connected to the third support unit 403 .

[0062] In any embodiment of the present technical solution, optionally, the first linear guide rails are multiple and arranged in parallel, and the second linear guide rails are multiple and arranged in parallel; the first slide grooves are multiple and correspond one-to-one with the first linear guide rails, and the second slide grooves are multiple and correspond one-to-one with the second linear guide rails.

[0063] By providing multiple linear guide rails for guidance, the stability of the lifting device movement can be further improved.

[0064] In an embodiment of the present technical solution, optionally, the driving device is a driving cylinder or a driving motor.

[0065] In the various embodiments of this technical solution, the specific type of driving device is not limited. When the driving device is a driving cylinder, its driving stability is better; when the driving device is a driving motor, it can achieve flexible adjustment of the driving displacement, thereby achieving the adjustment of different lifting positions of the lifting device.

[0066] In each embodiment of the present technical solution, the specific materials of the fixing plate, support plate and connecting plate are not limited. In order to make the structure of the lifting device more stable, a 20-30 mm steel plate can be selected to avoid shaking of the lifting device during movement, thereby achieving smooth lifting movement.

[0067] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
