DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example

[0034] Reference Figure 1-4 The utility model provides an embodiment: an adjustable publicity column, comprising a lifting plate 3, a publicity main plate 1 and two adjustment mechanisms 2, and through holes 7 are provided on both sides of the upper end surface of the lifting plate 3;

[0035] Positioning holes 5 are provided on both sides of the upper end surface of the propaganda main board 1, and semicircular threaded rods 8 are fixedly provided on both sides of the lower end surface of the propaganda main board 1 and both ends of the lifting plate 3;

[0036] The adjustment mechanism 2 includes a rotating rod 208, a rotating seat 202 is rotatably provided at the lower end of the rotating rod 208, a supporting leg 201 is fixedly provided at the lower end of the rotating seat 202, and a fixing frame 209 is fixedly provided at the center of the upper end surface of the supporting leg 201;

[0037] A poster tube 203 is movably sleeved on the body of the rotating rod 208, a trapezoidal slot 204 is provided inside the poster tube 203, a trapezoidal clip strip 205 is movably provided inside the trapezoidal slot 204, a positioning bearing 206 is fixedly sleeved at the upper end of the body of the rotating rod 208, and a vertical wind wheel 207 is fixedly provided at the upper end of the rotating rod 208;

[0038] The positioning bearing 206 allows the rotating rod 208 to rotate more smoothly.

[0039] An observation window 6 is provided at the front end of the promotional main board 1, and a glass plate 4 is fixedly arranged inside the observation window 6 near the front end, which plays a dust-proof role. One end of the trapezoidal clamping strip 205 is fixedly connected to the rotating rod 208, and the upper end of the fixing frame 209 is fixedly connected to the front end of the promotional main board 1. The trapezoidal clamping strip 205 is clamped in the trapezoidal clamping groove 204, which facilitates the rotation of the rotating rod 208 and the up and down movement of the poster tube 203. The outer ring of the positioning bearing 206 is fixedly sleeved inside the positioning hole 5 to increase the stability of the rotation of the rotating rod 208.

[0040] The rotating rod 208 is located inside the through hole 7, and the poster tube 203 is located at the upper end of the lifting plate 3. The lifting plate 3 is used to lift the poster tube 203. The diameter of the through hole 7 is smaller than the diameter of the poster tube 203 and larger than the diameter of the rotating rod 208, which is convenient for the lifting plate 3 to lift the poster tube 203 without affecting the rotation of the rotating rod 208. The four semicircular threaded rods 8 are grouped in pairs up and down to form two complete external threaded rods, which are easy to fix through external nuts.

[0041] The utility model utilizes wind energy to drive the vertical wind wheel 207 to rotate, and drives the poster tube 203 to rotate through the rotating rod 208, so as to realize the automatic rolling display of the poster. This mechanism does not require additional energy supply, which saves energy and reduces environmental pressure.

[0042] The simple poster replacement mechanism allows the lifting plate 3 to be quickly removed by removing two nuts, thereby easily replacing posters. This feature greatly improves the convenience of operation compared to the traditional method of completely disassembling the publicity board.

[0043] With the help of the positioning bearing 206, the rotating rod 208 can rotate more smoothly, further improving the stability and aesthetics of the poster during display.

[0044] A glass plate 4 is fixedly arranged inside the observation window 6 at the front end of the promotion main board 1, close to the front end, to provide dust protection for the displayed posters and keep the displayed content clear and tidy.

[0045] The design of the poster tube 203, the trapezoidal slot 204 and the trapezoidal clip strip 205 facilitates the rotation of the rotating rod 208 and the upward and downward movement of the poster tube 203. This structural design effectively improves the convenience in use.

[0046] The outer ring of the positioning bearing 206 is designed to be fixedly sleeved inside the positioning hole 5, which increases the stability of the rotating rod 208 when rotating and ensures the overall stability of the publicity column.

[0047] The lifting plate 3 is specially designed to lift the poster tube 203 through the designed through hole 7, thereby ensuring the stable support of the poster tube 203. At the same time, this structural design also ensures the smooth rotation of the rotating rod 208 without being affected.

[0048] The semicircular threaded rod 8 structural design adopted allows for quick fixation via nuts during assembly, thus improving the assembly efficiency and stability of the entire billboard.

[0049] Working principle: During installation, you only need to wrap the poster around the two poster tubes 203, and then push the lifting plate 3 upwards. The lifting plate 3 moves upwards to make the poster tube 203 move upwards and enter the interior of the promotional main board 1. At the same time, the semicircular threaded rods 8 are combined in pairs and then fixed with nuts to store the poster inside the promotional main board 1. The installation of the poster is very convenient and the adjustment is very convenient. When the external wind blows the vertical wind wheel 207, the vertical wind wheel 207 rotates to drive the rotating rod 208 to rotate, and the rotating rod 208 rotates to drive the poster tube 203 to rotate, thereby realizing the automatic movement of the poster, which is energy-saving and environmentally friendly.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
