[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1 As shown, this utility model provides a technical solution: a product lifting device, including a support structure 1 for supporting an upper component, four lifting structures 3 for lifting the upper component are fixedly connected to the top of the support structure 1, and a fixing structure 2 is fixedly connected to the top of the four lifting structures 3.

[0019] The support structure 1 provides a stable base for the whole, and the four lifting structures 3 can achieve smooth lifting and lowering of the fixed structure 2 through synchronous transmission, which solves the problem of easy tilting of traditional single-drive devices. The fixed structure 2 can ensure product safety during the lifting process. The three work together to give the device the advantages of efficient lifting and reliable fixation.

[0020] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the support structure 1 includes a base plate 11, and a support column 12 is fixedly connected to the top of the base plate 11. The fixing structure 2 includes a second support plate 22, and a connecting plate 24 is fixedly connected to the top of the second support plate 22. A groove 28 is provided inside the second support plate 22. A support block 23 is slidably connected inside the connecting plate 24. Clamping blocks 25 are fixedly connected to both ends of the top of the support block 23. Four limiting blocks 27 are fixedly connected to the top of the second support plate 22. The four limiting blocks 27 are located around the connecting plate 24. Circular holes 21 are provided around the second support plate 22.

[0021] The support structure 1, consisting of the base plate 11 and the support column 12, can evenly transmit the upper load to the ground and prevent the entire device from shaking. In the fixing structure 2, the limiting block 27 can initially limit the product position, the sliding support block 23 and the clamping block 25 can adapt to and clamp products of different sizes, and the round hole 21 can assist in inserting fixing parts. The multiple fixing design completely solves the problem of products easily shifting and falling during manual lifting, ensuring operational safety.

[0022] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the lifting structure 3 includes a column 31, a connecting block 36 is fixedly connected inside the column 31, a threaded rod 34 is rotatably connected inside the connecting block 36, a first gear 33 is fixedly connected to the bottom of the threaded rod 34, a lifting rod 35 is threadedly connected to the outside of the threaded rod 34, a motor 32 is fixedly installed on one side of the column 31, a second gear 37 is fixedly connected to the output end of the motor 32, and the second gear 37 meshes with the first gear 33.

[0023] The lifting structure 3 adopts a gear-thread transmission system of motor 32. Motor 32 drives the second gear 37 to rotate the first gear 33, which in turn causes the threaded rod 34 to rotate. The threaded engagement converts the rotational motion into the linear motion of the lifting rod 35. Compared with pneumatic and hydraulic equipment, it is easier to achieve precise control, and the structure is simple and easy to maintain, providing a reliable power foundation for the smooth lifting of the fixed structure 2.

[0024] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the lifting rod 35 is slidably connected inside the column 31, and the output end of the motor 32 passes through one side of the column 31.

[0025] The column 31 provides axial support for the lifting rod 35, preventing it from rotating with the threaded rod 34 and ensuring precise and stable lifting motion. The design of the motor 32 output end passing through the column 31 makes the gear transmission structure compact, reduces space occupation, and ensures efficient power transmission, providing structural guarantee for the lifting rod 35 to drive the fixed structure 2 to accurately adjust the height.

[0026] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, four lifting rods 35 are slidably connected inside the second support plate 22.

[0027] The sliding connection between the four lifting rods 35 and the second support plate 22 not only enhances the connection stability but also ensures uniform force during lifting and lowering, preventing the fixed structure 2 from tilting. Combined with the limiting clamping function of the fixed structure 2, the product position can be kept stable while the height can be precisely adjusted, making it suitable for precision operation requirements.

[0028] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the second gear 37 is located between the first gear 33 and the connecting block 36.

[0029] The gear position design enables more balanced transmission force, avoids deformation of the first gear 33 due to concentrated force, ensures the stability and durability of gear meshing transmission, and thus ensures smooth lifting of the lifting rod 35, providing a continuous and stable lifting environment for the product on the fixed structure 2.

[0030] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the support column 12 is fixedly connected to the bottom of the second support plate 22.

[0031] The support column 12 connects the base plate 11 and the second support plate 22 to form an auxiliary support structure 1, which can share the load of the lifting rod 35, reduce the stress on the lifting structure 3, and enhance the anti-shaking ability of the fixed structure 2, so that the product is not easy to shift even if it is subjected to slight external force after being fixed.

[0032] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, four columns 31 are fixedly connected to the top of the base plate 11.

[0033] The four columns 31 are evenly distributed on the top of the base plate 11, which can evenly transmit the power and load of the lifting structure 3 to the foundation support structure 1, avoiding excessive local stress that could damage the device, and at the same time providing a reference for the synchronous movement of the four lifting rods 35.

[0034] Working principle: After the motor 32 is started, the output end of the motor 32 begins to rotate, driving the second gear 37, which is fixedly connected to it, to rotate synchronously. Since the second gear 37 meshes with the first gear 33 and the second gear 37 is located between the first gear 33 and the connecting block 36, the meshing transmission of the gears will transmit the rotational power of the motor 32 to the first gear 33, causing the first gear 33 to rotate accordingly. The rotation of the first gear 33 is converted into the linear lifting motion of the lifting rod 35 through a mechanical connection. The first gear 33 is fixedly connected to the bottom of the threaded rod 34. Therefore, the rotation of the first gear 33 will directly drive the threaded rod 34 to rotate synchronously inside the connecting block 36. The connecting block 36 is fixed inside the column 31, providing stable rotational support for the threaded rod 34. The threaded rod 34 is externally threaded with the lifting rod 35, and the lifting rod 35 is slidably connected inside the column 31. The inner wall of the column 31 limits the lifting rod 35, restricting it from rotating with the threaded rod 34.

[0035] The tops of the four lifting rods 35 are all fixedly connected to the second support plate 22 of the fixed structure 2, and the lifting rods 35 are slidably connected inside the second support plate 22 to improve the connection stability. Therefore, the synchronous lifting of the four lifting rods 35 will drive the entire fixed structure 2 to move up and down together. The support structure 1 provides basic support for the device: the base plate 11 serves as the bottom base to bear the overall weight, and the support column 12 is fixedly connected to the top of the base plate 11 and the bottom of the second support plate 22 to help strengthen the stability of the fixed structure 2. When the product is placed on the second support plate 22 of the fixed structure 2, the four limiting blocks 27 around the perimeter can initially limit the position of the product to prevent the product from shifting horizontally. The support block 23 slidably connected inside the connecting plate 24 and the clamping block 25 at the top can further clamp the product. It needs to be used in conjunction with external operation or additional drive structure. The original text does not specify the drive method, but it is speculated to be manual adjustment or linkage adjustment. The round holes 21 around the second support plate 22 can be used to insert fixing parts to further lock the product or auxiliary fixing parts to the fixed structure 2.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
