[0022] In this embodiment, the fixed column 1 serves as the base support structure of the lifting column, providing installation space for components such as the movable column and gas spring. The gas spring 2 drives the lifting of the movable column through its telescopic function. The use of the gas spring enables the lifting column to automatically complete the lifting without external power. The movable column 3 slides out of or retracts into the fixed column as the gas spring extends or retracts. The lifting of the movable column achieves the main function of the lifting column. The fixed sleeve 4 provides a mounting base for the sealing sleeve and cleaning brush and allows the movable column to slide smoothly within it. The design of the sealing sleeve 5 effectively prevents dust and other impurities from entering the interior of the fixed column, ensuring the normal use of the lifting column. The sealing sleeve can rotate with the lifting of the movable column, maintaining the sealing effect. The cleaning brush 6 is used to clean the impurities on the top of the fixed column. During the use of the lifting column, it can automatically clean the top of the fixed column, maintaining its cleanliness and further extending the service life of the lifting column. The design of the butt joint block 7 allows the sealing sleeve and cleaning brush to be easily stored when not in use, avoiding affecting the lifting operation of the lifting column while maintaining the sealing effect. When the lifting column is in the lowered state, the sealing sleeve and cleaning brush can be easily stored in the clamping groove 8, avoiding collisions or wear and tear with the ground or other objects, improving the safety and reliability of the lifting column.

[0023] In further preferred embodiments of the present application, the sealing sleeve 5 is composed of a sealing tube and a guide tube. The sealing tube is slidably sleeved outside the movable column 3. The guide tube is fixedly connected with the cleaning brush 6. The top of the guide tube is designed to be inclined with the center being higher and the periphery being lower.

[0024] In this embodiment, the sealing sleeve 5 is further optimized to be composed of a sealing tube and a guide tube. This design not only maintains the original sealing function but also improves the rationality and practicality of the structure. The material and design of the sealing tube ensure its good sealing performance and wear resistance, effectively preventing dust and other impurities from entering the interior of the fixed column. The guide tube provides stable support and guidance for the cleaning brush. The top of the guide tube is designed to be inclined with the center being higher and the periphery being lower. The sealing sleeve 5 can throw off the impurities on it during rotation, ensuring the sealing effect. This optimized design not only improves the reliability and safety of the lifting column but also extends its service life and reduces maintenance costs.

[0025] In further preferred embodiments of the present application, the movable column 3 is fixedly installed with a limiting block 10 on the part inside the fixed column 1. The bottom of the fixed sleeve 4 is fixedly installed with a fixed gear 9. The fixed gear 9 is movably sleeved on the movable column 3. The fixed gear 9 is arranged between the top inner wall of the fixed column 1 and the limiting block 10. A lead screw 11 is rotatably installed in the fixed column 1. The lead screw 11 is threadedly and slidably connected with the limiting block 10. A drive gear 12 is fixedly installed on the lead screw 11. The drive gear 12 is engaged with the fixed gear 9.

[0026] In the embodiment, the limiting block 10 is used to limit the descending position of the movable column 3, preventing it from descending excessively and damaging the lifting column structure. The fixed gear 9 is engaged with the driving gear 12 for power transmission, realizing the driving of the fixed sleeve 4 and the sealing sleeve 5 by the screw rod 11. By pressing the movable column 3 downward by external force, the movable column 3 drives the limiting block 10 to descend, and the limiting block 10 is in sliding connection with the screw rod thread, so that the screw rod 11 can convert the vertical downward movement of the limiting block 10 into the rotating movement of the screw rod 11, the screw rod 11 drives the driving gear 12 to rotate, and then drives the fixed sleeve 4 and the sealing sleeve 5 to rotate, shakes off the impurities accumulated on the sealing sleeve 5, and at the same time, the rotating of the cleaning brush sweeps the surrounding impurities. Through the rotation of the fixed sleeve 4 and the sealing sleeve 5 and the sweeping effect of the cleaning brush, the accumulation of impurities on the top of the lifting column is effectively prevented, and the cleanliness and service life of the lifting column are improved.

[0027] In the further preferred embodiment of the utility model, the top of the butt joint block 7 is provided with a ring-shaped notch, and a warning light strip 13 for reminding pedestrians or drivers to pay attention is fixedly installed in the ring-shaped notch.

[0028] In the embodiment, the design of the ring-shaped notch provides space for the installation of the warning light strip 13, so that the warning light strip 13 can be stably fixed on the butt joint block 7. The warning light strip 13 is used to remind pedestrians or drivers to pay attention, avoiding collision accidents caused by unclear vision. The warning light strip 13 can emit bright light to warn pedestrians or drivers not to approach or hit the lifting column, especially at night or in poor visibility, which can effectively warn. When the lifting column is in the raised state, the butt joint block 7 and the warning light strip 13 thereon will be located at the top of the lifting column, forming an obvious warning sign. At this time, the warning light strip 13 can emit bright light to remind pedestrians or drivers to pay attention, avoiding collision accidents. This optimized design not only improves the safety of the lifting column, but also makes the appearance of the lifting column more beautiful and practical, enhances the visual effect and warning effect.

[0029] In the further preferred embodiment of the utility model, a guide rod 14 is rotatably installed in the fixed column 1, and the guide rod 14 slidably penetrates the limiting block 10.

[0030] In this embodiment, the design of the guide rod 14 provides stable guidance for the lifting of the limit block 10 and the movable column 3, ensuring that the lifting process is more stable and controllable. The gas spring 2 pushes the movable column 3 upwards, and the sliding through action of the guide rod 14 during the lifting process ensures that the limit block 10 does not deviate from the track during the lifting process, thereby ensuring the stability and reliability of the lifting column. The design of the guide rod 14 also enhances the load-bearing capacity of the lifting column. Because the guide rod 14 provides additional support for the lifting process, the lifting column can maintain stability and reliability even when subjected to a large load. This optimized design not only improves the lifting performance and stability of the lifting column, but also makes the structure of the lifting column more compact and reasonable, reducing manufacturing and maintenance costs.

[0031] In further preferred embodiments of the present application, the guide rod 14 is fixedly installed with a clamping block 15, and the limit block 10 is provided with a corresponding butt joint groove 16. When the movable column 3 is lowered, the clamping block 15 is used, and the limit block 10 is fixedly installed with a stop block 17 at both ends. The stop block 17 is in sliding contact with the clamping block 15.

[0032] In this embodiment, the design of the clamping block 15 provides additional limiting and stabilizing effects for the movable column 3. When the movable column 3 needs to be lowered, the clamping block 15 is aligned with the butt joint groove 16, allowing the movable column 3 to slide along the guide rod 14. When the clamping block 15 is misaligned with the butt joint groove 16, the movable column 3 is locked and cannot slide. The design of the stop block 17 limits the alignment of the clamping block 15 and the butt joint groove 16. When the clamping block contacts the stop block, the clamping block 15 and the butt joint groove 16 are on the same horizontal line, and can slide through the butt joint groove 16. The introduction of the clamping block 15, the butt joint groove 16 and the stop block 17 realizes the locking and unlocking of the movable column 3, further improving the stability and reliability of the lifting column.

[0033] In further preferred embodiments of the present application, the top of the fixed column 1 is provided with an operation groove 18, and the top of the guide rod 14 is fixedly installed with an adjusting block 19, which extends into the operation groove 18.

[0034] In the embodiment, the design of the operation groove 18 enables the user to operate the adjusting block 19 through an external tool, thereby achieving the adjustment and control of the guide rod 14. The adjusting block 19 provides an operable interface for the user, and the user can rotate the guide rod 14 by operating the adjusting block 19, thereby achieving the adjustment and control of the lifting process of the movable column 3. When the lifting column needs to be adjusted, the user can extend the corresponding operating rod into the operation groove 18 to rotate the adjusting block 19. Since the adjusting block 19 is fixedly connected with the guide rod 14, rotating the adjusting block 19 will drive the guide rod 14 to rotate. After the operation groove 18 and the adjusting block 19 are introduced, the user can more conveniently adjust and control the lifting column without disassembling other components of the lifting column, thereby improving the adjustment performance and ease of use of the lifting column and making the structure of the lifting column more compact and reasonable.

[0035] In summary, compared with the related art, the introduction of the sealing sleeve and the cleaning brush effectively prevents impurities such as dust from entering the inside of the fixed column and automatically cleans the impurities on the top of the fixed column, thereby ensuring the normal use of the lifting column and prolonging the service life. The design of the guide rod and the limiting block provides stable guidance and limiting for the lifting of the movable column, thereby ensuring the stability and controllability of the lifting process. In addition, the introduction of the clamping block, the butt joint groove, and the stop block further improves the locking and unlocking performance of the lifting column, thereby enhancing the stability and reliability of the lifting column. The design of the operation groove and the adjusting block enables the user to conveniently adjust and control the lifting column through an external tool without disassembling other components, thereby improving the adjustment performance and ease of use of the lifting column. This design also makes the structure of the lifting column more compact and reasonable. The installation of the warning light strip on the butt joint block effectively reminds pedestrians or drivers to pay attention, thereby avoiding collision accidents caused by unclear vision. This design not only improves the safety of the lifting column but also enhances the visual effect and warning effect of the lifting column.
