Technical Field

[0001] This utility model belongs to the technical field of lifting table frames, specifically relating to a lifting table frame with a telescopic connection structure. Background Technology

[0002] A height-adjustable desk frame, also known as a height-adjustable desk frame, is a type of desk frame whose height can be adjusted according to the user's needs. In traditional height-adjustable desk frames, the length of the crossbeam is usually fixed. However, the desk board comes in various lengths such as 1.2m, 1.5m, and 1.8m.

[0003] To accommodate tabletops of varying lengths, crossbeams of different lengths must be produced, undoubtedly increasing production complexity and costs. In packaging, the varying crossbeam lengths necessitate the use of different sized packaging materials, further increasing costs. During processing, the diverse crossbeam specifications require frequent mold changes and adjustments to process parameters, reducing production efficiency. In terms of transportation, the different lengths of crossbeams occupy varying amounts of space, leading to reduced space utilization in transport vehicles and increased transportation costs.

[0004] Therefore, in order to solve the above problems, it is necessary to design a height-adjustable table frame with a telescopic connection structure. Utility Model Content

[0050] like Figures 1 to 4 As shown, this embodiment provides a height-adjustable table frame with a telescopic connection structure, including:

[0051] Two lifting columns 1 and a telescopic crossbeam 2 disposed between the two lifting columns 1; wherein the telescopic crossbeam 2 includes: two stacked inner tubes 201 and outer tubes 202 sleeved at both ends of the two inner tubes 201; wherein the two outer tubes 202 are respectively connected to the two lifting columns 1; and the two inner tubes 201 are adapted to slide within the two outer tubes 202 to adjust the distance between the two lifting columns 1.

[0052] In this embodiment, when it is necessary to adjust the distance between the two lifting columns 1, the two inner tubes 201 are pulled to slide within the outer tube 202, thereby adjusting the length of the telescopic beam 2 to adjust the distance between the two lifting columns 1. By setting the telescopic beam 2, the problem of the fixed length of the beam of the traditional lifting table frame and its inability to adapt to various table lengths is effectively solved, while reducing production costs, packaging costs, transportation costs and improving production efficiency.

[0053] The telescopic crossbeam 2 further includes at least two set screws 203; wherein the set screws 203 are adapted to penetrate the bottom of the outer tube 202 and the lower inner tube 201, and engage with the lower inner tube 201; and after engaging with the lower inner tube 201, the set screws 203 abut against the bottom of the upper inner tube 201, so that the upper inner tube 201 and the lower inner tube 201 are tightly abutted against the inner wall of the outer tube 202; wherein by setting the set screws 203 and engaging with the lower inner tube 201, when the set screws 203 are tightened, the set screws 203 move upward to generate contact pressure with the bottom of the upper inner tube 201, so that the two inner tubes 201 move away from each other, so that the two inner tubes 201 are tightly abutted against the inner wall of the outer tube 202, thereby achieving a tight lock of the three-layer tube structure, so that the telescopic crossbeam 2 can remain stable after the length is adjusted, and improving the stability and safety of the entire table frame structure.
