DETAILED DESCRIPTION

[0018] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figures 1 to 4 As shown, a portable billboard includes a supporting tube 1 and a billboard body 2, and the billboard body 2 is fixedly arranged at the upper end of the supporting tube 1, and a slidable hollow tube 3 is arranged in the supporting tube 1. By adjusting the position of the hollow tube 3 in the supporting tube 1, the height of the billboard body 2 can be adjusted, and a fixing mechanism 5 is arranged between the supporting tube 1 and the hollow tube 3. Then, the fixing mechanism 5 can be used to fix the supporting tube 1 and the hollow tube 3, so as to fix the adjusted height of the billboard for people to watch.

[0020] The fixing mechanism 5 includes a plurality of fixing pins 13, push columns 14 are provided on both sides of the support tube 1, slide grooves 15 are provided on both sides of the hollow tube 3, and the tail ends of the push columns 14 are slidably located in the slide grooves 15, two fixing blocks 16 are arranged in the hollow tube 3, and one end of the two push columns 14 is fixedly connected to the fixing blocks 16 respectively, and by pressing the two push columns 14 inward, the fixing blocks 16 can be driven to move inward. The two pressing columns 14 are respectively provided with a return spring 17, and the return spring 17 is connected between the top of the pressing column 14 and the outer wall of the supporting tube 1. Two rows of fixing holes 18 are respectively opened on both sides of the hollow tube 3. Every two fixing pins 13 are respectively fixed on the fixing block 16 and are respectively located in the fixing holes 18. When the fixing block 16 moves inward, the two fixing pins 13 can be driven to disengage from the fixing holes 18 respectively. At this time, the return spring 17 is squeezed to generate elastic force, and then the supporting tube 1 can be pulled, so that the supporting tube 1 slides upward along the hollow column 8. At this time, the pressing column 14 slides along the slide groove 15 at the same time. When the supporting tube 1 is adjusted to a suitable position, the fixing block 16 can be driven back to the initial position by the return action of the return spring 17, so as to drive the fixing pin 13 to be pushed into the corresponding fixing hole 18 again, so that the fixation between the hollow tube 3 and the supporting tube 1 can be achieved, and finally the height of the billboard body 2 can be adjusted.

[0021] A base 4 is provided below the support tube 1, and the lower end of the hollow tube 3 is fixedly connected to the base 4, grooves 6 are provided on both sides of the support tube 1, and adjustment grooves 7 are provided on both sides of the groove 6. A hollow column 8 is provided in the groove 6, and both ends of the hollow column 8 are slidably located in the two adjustment grooves 7 respectively, a support column 9 is provided in the groove 6, and the support column 9 is fixed on the hollow column 8, a supporting mechanism 10 is provided in the base 4, and the supporting mechanism 10 cooperates with the supporting column 9. When the billboard is adjusted to a suitable height, the height and expansion angle of the supporting column 9 can be adjusted by sliding up and down and rotating the hollow column 8, and finally the supporting mechanism 10 can be cooperated to support the billboard, so that the billboard is more stable after being placed, further improving the practicality of the billboard.

[0022] Two rows of limit holes 11 are symmetrically opened on one side of the support tube 1, and each row of limit holes 11 is respectively connected with the adjustment groove 7. A limit pin 12 is passed through the limit hole 11, and the top end of the limit pin 12 is located in the hollow column 8. When the support column 9 moves up and down along the adjustment groove 7 for adjustment, the hollow column 8 can be driven to slide up and down along the adjustment groove 7. Then, the limit pin 12 can be passed through the corresponding limit hole 11, and the top end of the limit pin 12 can be inserted into the hollow column 8 to fix the hollow column 8, which can further improve the support stability of the billboard to prevent the billboard from tipping over after placement.

[0023] The supporting mechanism 10 includes two supporting legs 19, which are slidably located in the base 4 respectively. Two fixing screws 20 are passed through the base 4. A plurality of connecting holes 21 are respectively opened on the two supporting legs 19, and the top ends of the fixing screws 20 are located in the connecting holes 21. A plurality of slots 22 are respectively provided on each supporting leg 19. An insert block 23 is fixed to the lower end of the supporting column 9, and the insert block 23 cooperates with the slot 22. By pulling the two supporting legs 19, the fixing screws 20 are passed through the base 4 so that the top ends of the fixing screws 20 are inserted into the connecting holes 21, so as to achieve the fixation between the supporting legs 19 and the base 4. Therefore, the supporting stability of the billboard can be improved by the supporting legs 19 contacting the ground. Then, the position of the supporting column 9 can be rotated and adjusted up and down so that the insert block 23 can be inserted into the corresponding slot 22. Finally, the supporting stability of the billboard can be further improved by the supporting column 9.

[0024] The bottoms of the two grooves 6 are respectively provided with fixing grooves 24, and the insert blocks 23 cooperate with the fixing grooves 24. When the billboard is carried, the insert blocks 23 can be inserted into the fixing grooves 24 to fix the fixing columns in the grooves 6. At the same time, the hollow tube 3 adopts a hollow design, which can further reduce the overall mass of the billboard, thereby further improving the portability of the billboard.

[0025] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
