[0036] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention.

[0038] Reference Figures 1-3As shown, a lifting column outer cylinder includes an outer cylinder body 1, an outer cylinder bottom plate 2, and a junction box 3 assembled together; a first flange 1-1 for receiving the lifting mechanism is integrally formed on the top of the outer cylinder body 1, and a plurality of connecting holes 1-2 are provided on the first flange 1-1, preferably four connecting holes 1-2; a second flange 1-3 is integrally formed on the bottom of the outer cylinder body 1, and the outer cylinder bottom plate 2 is installed and fixed on the second flange 1-3; the junction box 3 is installed on the upper side of the outer wall of the outer cylinder body 1, and a drain hole 4 is provided on the lower side of the outer wall of the outer cylinder body 1.

[0039] The outer cylinder 1 and its first flange 1-1 are made by rolling and flanging processes. The connecting hole 1-2 has a downwardly extending extension connecting part 1-4 obtained by melt drilling. The extension connecting part 1-4 is preferably a threaded connecting part to facilitate connection.

[0040] Since the outer cylinder 1 and the first flange 1-1 are formed by rolling and flanging, and the connecting hole 1-2 and the extension connecting part 1-4 on the first flange 1-1 are obtained by melting and drilling, the outer cylinder 1, the first flange 1-1 and the extension connecting part 1-4 are an integral structure of the same material, which has greater structural strength, better reliability, fewer parts, simpler process and higher production efficiency.

[0041] The junction box 3 can be obtained by stamping and flanging. The outer cylinder bottom plate 2 and the junction box 3 can be fixed to the outer cylinder 1 by welding, riveting and other processes.

[0042] Compared with existing technologies, the lifting column outer cylinder provided in this embodiment facilitates the assembly of the lifting mechanism and the lifting column outer cylinder by providing a first flange 1-1 at the top of the outer cylinder 1 to support the lifting mechanism. After assembly, the first flange 1-1 provides load-bearing and limiting (limiting is achieved through the upper flange of the first flange 1-1), effectively improving the assembly stability and anti-collision performance of the lifting mechanism and making it less susceptible to damage from impacts. Simultaneously, by providing connecting holes 1-2 on the first flange and corresponding extension connecting parts 1-4, the lifting mechanism and the outer cylinder 1 can be reliably connected by bolts, facilitating installation and maintenance. Furthermore, the placement of the junction box 4 further facilitates cable routing and cable storage.

[0043] Furthermore, in this embodiment, it is preferable to connect a plurality of support plates 5 between the outer wall of the outer cylinder 1 and the bottom side of the first flange 1-1, preferably four support plates 5. The support plates 5 are welded and fixed to the outer wall of the outer cylinder 1 and the bottom side of the first flange 1-1. Since the entire outer cylinder 1 is manufactured by a rolling and flanging process, the support plates 5 can further enhance the structural strength of the outer cylinder after rolling and flanging, ensuring the support effect of the first flange 1-1.

[0044] Preferably, each of the support plates 5 is further provided with a plurality of notches and slots 5-1. By providing notches and slots 5-1, the gripping effect of the outer cylinder of the lifting column can be enhanced, thereby enhancing the anti-collision performance of the lifting column.

[0045] Reference Figure 4 , Figure 5 As shown, the anti-collision lifting column of this utility model includes an inner cylinder 6, an outer cylinder 7 and a lifting mechanism 8 assembled together. A guide column 9 is provided in the outer cylinder 7. The inner cylinder 6 is connected to the guide column 9 through a guide hole. The lifting mechanism 8 is installed in the outer cylinder 7 to push the inner cylinder 6 to move up and down along the height direction of the outer cylinder 7. The structure of the outer cylinder 7 is as described above.

[0046] The lifting mechanism 8 has a mounting flange 8-1 that mates with the first flange 1-1. A clamping mounting plate 10 is provided corresponding to the mounting flange 8-1. Through holes corresponding to the connecting holes 1-2 are provided on the mounting flange 8-1 and the clamping mounting plate 10. A bolt 11 passes through each through hole and the connecting hole to lock and fix the lifting mechanism 7 to the outer cylinder of the lifting column.

[0047] Here, the connection structure using mounting flange 8-1, clamping mounting plate 10, and bolt locking not only ensures a stable and reliable connection but also facilitates disassembly and maintenance.

[0048] Reference Figures 6-8 As shown, the inner cylinder 6 includes an inner cylinder body 6-1 and a first guide ring 6-2 formed by folding the lower end of the inner cylinder body 6-1 outward. The first guide ring 6-2 is an integral structure with the inner cylinder body 6-1. The first guide ring 6-2 is provided with a first groove hole 6-3, a first guide hole 6-4 and a first height limiting component mounting hole 6-5. There are at least two first guide holes 6-4 and at least three first height limiting component mounting holes 6-5. In this embodiment, three are preferred, arranged in a triangular pattern, which not only improves reliability but also avoids the assembly inconvenience caused by too many holes.

[0049] A second guide ring 6-6 is installed on the outer wall of the inner cylinder 6-1. The second guide ring 6-6 is provided with a second groove hole, a second guide hole and a second height limiter mounting hole that correspond to the first groove hole, the first guide hole and the first height limiter mounting hole, respectively.

[0050] A downward-protruding first height-limiting bolt 6-7 is installed in the mounting hole of the first height-limiting component, and preferably a first flexible pad is provided at the bottom of the first height-limiting bolt 6-7. A upward-protruding second height-limiting bolt 6-8 is installed in the mounting hole of the second height-limiting component, and a second flexible pad is provided at the top of the second height-limiting bolt 6-8. The flexible pad provides a better anti-collision effect.

[0051] Preferably, a bushing 6-9 that mates with the guide shaft is also provided on the first guide hole and the second guide hole. The bushing 6-9 has a through hole for the guide shaft to pass through. The inner wall of the through hole fits against the outer wall of the guide shaft, thereby ensuring the smooth lifting and stability of the inner cylinder of the lifting column.

[0052] A top cover 6-10 is installed on the top opening of the inner cylinder 6-1, and a connecting plate 6-11 for connecting the lifting device is installed on the top cover 6-10. The top cover 6-10 and the connecting plate 6-11 are connected by bolts 6-12 to form a suspended connection, so that the connecting plate 6-11 extends into the inner cylinder 6-1. When assembling the inner cylinder of the lifting column with the lifting device, the lifting rod of the lifting device can be connected to the connecting plate 6-11 first, and then the top cover 6-10 can be installed on the top opening of the inner cylinder 6-1. The assembly is convenient and quick, effectively improving the connection and assembly efficiency between the inner cylinder of the lifting column and the lifting device.
