Detailed Implementation

[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] like Figures 1 to 2 As shown, this utility model provides a lifting mechanism, including an inner column 1. A gas spring assembly (not shown in the figure) is disposed inside the inner column 1. The gas spring assembly utilizes the compressibility of gas to provide lifting power. Simultaneously, the gas spring assembly has a buffering and damping effect, enabling a smoother lifting process and reducing impact and vibration. It should be noted that the gas spring assembly is prior art, and this utility model has also made improvements to this part; therefore, its principle and process will not be described in detail.

[0030] like Figure 2 , Figure 3As shown, in this embodiment, an outer column 2 is sleeved on the outer side of the inner column 1. Multiple first sliding grooves 11 are provided on the outer side of the inner column 1, and multiple second sliding grooves 21 are correspondingly provided on the inner side of the outer column 2. A sliding cavity 3 is formed between the first sliding grooves 11 and the corresponding second sliding grooves 21, and several sliding beads 4 are disposed within the sliding cavity 3. When the inner column 1 moves up and down within the outer column 2, the sliding beads 4 fill the sliding cavity 3 formed by the first sliding grooves 11 and the second sliding grooves 21. The sliding beads 4 roll within the sliding cavity 3, providing uniform support to the inner column 1 and reducing deviation and swaying. Compared to traditional mechanisms that rely solely on a large gap between the columns for movement, this invention reduces the gap between the inner column 1 and the outer column 2, providing more stable support and guidance. Furthermore, the sliding beads 4 use rolling friction instead of sliding friction, reducing frictional resistance during the lifting process, making the lifting process smoother, reducing stuttering and abnormal noise, and further improving the stability of the lifting process.

[0031] like Figure 4 , Figure 5 As shown, in this embodiment, the outer side of the inner column 1 protrudes outward to form a first sliding platform 12, and the side of the first sliding platform 12 is recessed inward to form a first sliding groove 11. The first sliding groove 11 provides installation space for the sliding ball 4, which can roll within the groove, reducing friction between the inner column 1 and the outer column 2. Furthermore, the recessed structure of the first sliding groove 11 provides a precise movement trajectory for the sliding ball 4, ensuring more stable movement of the inner column 1 within the outer column 2 and preventing wobbling or deviation. In addition, the first sliding platform 12 extends along the length of the inner column 1, providing a clear guide path for the sliding of the inner column 1, ensuring the straightness and stability of the lifting process.

[0032] like Figure 6 , Figure 7 As shown, in this embodiment, the inner side of the outer column 2 protrudes outward to form a second sliding platform 22, and the side of the second sliding platform 22 is recessed inward to form a second sliding groove 21. The second sliding groove 21 provides installation space for the sliding ball 4, which can roll within the groove, reducing friction between the inner column 1 and the outer column 2. Furthermore, the recessed structure of the second sliding groove 21 provides a precise movement trajectory for the sliding ball 4, ensuring more stable movement of the inner column 1 within the outer column 2 and preventing wobbling or deviation. In addition, the second sliding platform 22 extends along the length of the outer column 2, providing a clear guide path for the sliding of the outer column 2, ensuring the straightness and stability of the lifting process.

[0033] like Figure 2 , Figure 8As shown, in this embodiment, a connecting column 5 is provided between the inner column 1 and the outer column 2. The connecting column 5 serves as an intermediate support component between the inner column 1 and the outer column 2, effectively distributing the load during the lifting process and improving the stability of the overall structure. Furthermore, the connecting column 5 is provided with multiple connecting protrusions that correspond one-to-one with the first sliding groove 11. The connecting protrusions are connected to the bottom of the inner column 1 through a first connecting member. The corresponding design of the connecting protrusions and the first sliding groove 11 ensures precise fit between the connecting column 5 and the inner column 1, avoiding installation errors.

[0034] In this embodiment, the connecting protrusion is provided with a plurality of first connecting holes, and the bottom of the first sliding groove 11 is provided with a plurality of second connecting holes. The first connector passes through the first connecting holes and engages with the second connecting holes to form a firm connection, thereby improving the strength and stability of the overall structure. In addition, the design of the first connector allows the connection between the connecting protrusion and the bottom of the inner column 1 to be easily disassembled and reinstalled, facilitating maintenance and replacement of components.

[0035] like Figure 2 , Figure 8 As shown, in this embodiment, the lifting mechanism also includes a mounting component 6. The bottom of the mounting component 6 is connected to the inner column 1, and the top of the mounting component 6 is connected to the mounting base 7. The mounting component 6 serves as a transition component between the inner column 1 and the mounting base 7, achieving a reliable connection between the two. Specifically, the bottom of the mounting component 6 is provided with an opening 61 corresponding to the first sliding groove 11, and at least a portion of the first sliding table 12 is disposed within the opening 61. The inner column 1 is provided with a third connecting hole, and the mounting component 6 is provided with a corresponding fourth connecting hole. The second connecting component passes through the third connecting hole and engages with the fourth connecting hole, ensuring a precise connection between the mounting component 6 and the inner column 1 and avoiding installation errors. In addition, the even distribution of multiple connecting holes can evenly transfer the load on the mounting base 7 to the inner column 1, avoiding local stress concentration. At the same time, the number and position of the connecting holes can be adjusted according to actual needs to adapt to different load and lifting height requirements. Secondly, the design of the second connector allows for easy disassembly and reinstallation of the connection between the mounting component 6 and the inner column 1, facilitating maintenance and component replacement. The tightening effect of the second connector enhances the connection strength between the mounting component 6 and the inner column 1, improving the overall structural load-bearing capacity. Thirdly, the second connector can be designed as a bolt or screw; in actual design, its structure can be tailored to specific needs.

[0036] In this embodiment, the mounting base 7 is provided with a fifth connecting hole, and the top of the mounting component 6 is correspondingly provided with a sixth connecting hole. The third connecting component passes through the fifth connecting hole and mates with the sixth connecting hole to ensure a precise connection between the mounting base 7 and the top of the mounting component 6. Furthermore, the design of the third connecting component allows for easy disassembly and reinstallation of the connection between the mounting base 7 and the top of the mounting component 6, facilitating maintenance and component replacement. Additionally, the even distribution of multiple fifth and sixth connecting holes helps to evenly distribute the load on the mounting base 7, improving the overall load-bearing capacity of the structure. Secondly, the third connecting component can be designed as a bolt or screw; its structure can be customized according to actual needs. Thirdly, the mounting base 7 connects to the desktop board, thereby enabling the desktop to rise and fall.

[0037] In this embodiment, a lifting switch (not shown in the figure) is provided on the mounting component 6. The lifting switch is connected to the gas spring assembly, allowing the user to easily control the movement of the lifting mechanism by operating the lifting switch. The lifting switch controls the working state of the gas spring assembly (such as inflating or deflating) to achieve the lifting function of the lifting mechanism. It should be noted that the lifting switch controlling the working state of the gas spring assembly is existing technology, and this utility model is an improvement on this part; therefore, its principle and process will not be described in detail.

[0038] like Figure 1 , Figure 2 As shown, in this embodiment, the lifting mechanism also includes a protective column 8, which is sleeved on the outside of the outer column 2, and the top of the protective column 8 is connected to the mounting component 6. During the lifting process, it can effectively prevent the inner column 1 from being damaged by the external environment and extend the service life of the inner column 1. In addition, as an external support structure, the protective column 8 can enhance the rigidity and stability of the overall lifting mechanism.

[0039] In use, the mounting base 7 is connected to a desktop wooden board or the like. The gas spring assembly is controlled by the lifting switch to drive the inner rod to rise and fall along the outer rod. The sliding ball 4 rolls in the sliding cavity 3, which can evenly support the inner column 1 and reduce the deviation and shaking of the inner column 1.
