[0029] See also Figures 1 to 6The embodiment of the utility model provides a column structure for a parasol, including a main column 1 and a secondary column 2, wherein the secondary column 2 is sleeved in the main column 1, a plurality of pulleys 3 are arranged on the outside of the secondary column 2, a guide groove 101 adapted to the pulley 3 is arranged on the inside of the main column 1, and the main column 1 and the secondary column 2 are slidably connected through the pulley 3 and the guide groove 101. By adopting a double-layer column structure of the main column 1 and the secondary column 2, and sleeved the secondary column 2 in the main column 1, the stability of the column structure is enhanced, so that the column structure is not easily broken when encountering strong winds. In addition, by adopting a method of arranging the pulley 3 on the outside of the secondary column 2 and the guide groove 101 on the inside of the main column 1, when the motor 7 drives the secondary column 2 to rise or fall to fold or open the parasol, the lifting action of the secondary column 2 is smoother.

[0030] Among them, specifically, Figure 4 and Figure 5 As shown, the main column 1 and / or the auxiliary column 2 are multi-layer hollow structures, that is, the main column 1 can be set as a multi-layer hollow structure, or the auxiliary column 2 can be set as a multi-layer hollow structure, or both the main column 1 and the auxiliary column 2 can be set as a multi-layer hollow structure, which can further enhance the wind resistance of the column structure, so that the column structure composed of the main column 1 and the auxiliary column 2 is not easy to be broken. Among them, when the main column 1 and the auxiliary column 2 are both set as multi-layer hollow structures, the wind resistance of the column structure is the strongest and the structural stability is better.

[0031] Among them, preferably Figure 4 and Figure 5 As shown, the cross-sectional shape of the main column 1 and / or the auxiliary column 2 is a double-layer polygon, which not only improves the wind resistance of the column, but also facilitates the installation of the auxiliary column 2 inside the main column 1 without hindering the movement of the auxiliary column 2. Among them, the cross-sectional shape of the main column 1 and / or the auxiliary column 2 can be preferably a double-layer octagonal shape for easy processing. Of course, the cross-sectional shape of the main column 1 and / or the auxiliary column 2 can also be set to other shapes, and the utility model is not limited here.

[0032] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the main column 1 and / or the auxiliary column 2 include a plurality of hollow trapezoidal structures adjacent to each other in sequence, wherein the main column 1 is an integrally formed aluminum profile structure. By adopting a plurality of hollow trapezoidal structures adjacent to each other in sequence, the stability and wind resistance of the column structure are enhanced; and the main column 1 adopts an integrally formed aluminum profile structure, which is convenient for processing and also improves the stability of the column structure.

[0033] Specifically, the heights of two adjacent trapezoidal structures are different, so that a guide groove 101 is formed between the two spaced trapezoidal structures; because the outer wall of the secondary column 2 and the higher trapezoidal structures in the inner wall of the main column 1 are abutted and connected, the lower trapezoidal structures in the inner wall of the main column 1 form a sliding space for the pulley 3 between the outer wall of the secondary column 2, which can not only limit the secondary column 2, but also avoid uneven pressure on the inner side walls of the main column 1 due to the heavy weight of the secondary column 2, thereby improving the stability of the column structure.

[0034] Further, such as Figure 3 and Figure 4 As shown, a plurality of first grooves 102 for placing connecting wires can be provided on the outer side of the main column 1. When an ambient LED light or a lighting lamp is provided on the umbrella ribs or umbrella cloth, the connecting wires can be provided in the first grooves 102 and hidden, thereby improving the overall aesthetics of the parasol; also preventing consumers from accidentally touching the parasol during use, improving safety, and preventing the connecting wires from being damaged by external forces when the parasol is in use.

[0035] Among them, Figure 4 As shown, the first groove 102 is also provided with a closing cover 4 for closing the first groove 102, and the closing cover 4 is detachably connected to the first groove 102 to facilitate placement of the connecting wires or maintenance of the connecting wires.

[0036] In one embodiment, convex strips 1021 are provided on both side walls of the first groove 102 , and strip grooves 401 are provided on both sides of the closing cover 4 . The convex strips 1021 are detachably connected to the strip grooves 401 .

[0037] Or in another embodiment, strip grooves 401 are provided on both side walls of the first groove 102 , and convex strips 1021 are provided on both sides of the closing cover 4 , and the convex strips 1021 are detachably connected to the strip grooves 401 .

[0038] The above two embodiments facilitate installation and removal of the closing cover 4. Of course, the closing cover 4 and the first groove 102 may also be detachably connected by other connection structures, which is not limited in this embodiment.

[0039] The column structure of the utility model further includes a ball screw 5, which is arranged in the auxiliary column 2 and a nut seat 6 of the ball screw 5 is fixedly connected to the auxiliary column 2; when the motor 7 drives the ball screw 5 to rotate, the nut seat 6 drives the auxiliary column 2 to move up and down in the main column 1. The motor 7 can be arranged near the lower end of the ball screw 5, and after the shaft end of the ball screw 5 is connected to a linear gearbox or a right-angle gearbox through a joint, the gearbox is connected to the DC servo motor 7, so as to drive the ball screw 5 to rotate through the DC servo motor 7.

[0040] In summary, the column structure of the utility model enhances the stability of the column structure by adopting a double-layer column structure of a main column 1 and a secondary column 2, so that the column structure is not easily broken when encountering strong winds. In addition, by adopting a method of arranging a pulley 3 on the outside of the secondary column 2 and a guide groove 101 on the inside of the main column 1, when the motor 7 drives the secondary column 2 to rise or fall to fold or open the parasol, the lifting action of the secondary column 2 is smoother.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
