DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: an advertising display board support device that is convenient to adjust specifications, including: connecting block one 1 and connecting block two 12. Connecting block one 1 is in an L shape, connecting block one 1 is located at the lower end of connecting block two 12, and both connecting block one 1 and connecting block two 12 are symmetrically provided with two pieces. Limiting grooves one 2 and limiting grooves two 14 are respectively opened at the adjacent ends of connecting block one 1 and connecting block two 12. By inserting the advertising board into limiting grooves one 2 and limiting grooves two 14, it is fixed. A threaded column 10 is fixedly installed at the upper end of each connecting block one 1. A sliding hole 15 is opened on the side wall of one end of each connecting block two 12. The inner diameter of sliding hole 15 is larger than the diameter of threaded column 10. The upper end of threaded column 10 passes through sliding hole 15. Two adjusting nuts 11 are threadedly connected to the outer wall of each threaded column 10. The two adjusting nuts 11 are respectively located at the upper and lower ends of connecting block two 12. By rotating the adjusting nuts 11, the position of connecting block two 12 on threaded column 10 can be changed, thereby changing the distance between connecting block two 12 and connecting block one 1, so that advertising boards of different heights can be placed between connecting block one 1 and connecting block two 12.

[0024] Fixed plates 4 are installed at the lower ends of the two connecting blocks one 1 through support rods 3. One end of support rod 3 is fixedly installed on the side wall at the lower end of connecting block one 1, and the other end is fixedly installed at the center of the side wall at the upper end of fixed plate 4. A number of fixing holes are evenly opened on the outer side wall of fixed plate 4. Support rod 3 supports connecting block one 1 and connecting block two 12. Fixed plate 4 increases the contact area between support rod 3 and the ground, thereby stably supporting connecting block one 1 and connecting block two 12.

[0025] Or the connecting block one 1 and the connecting block two 12 can be fixedly fixed by passing a fixing rod through the fixing hole and driving it into the ground.

[0026] The two connecting blocks 1 are slidably connected by the strip plate 1, and the two connecting blocks 2 12 are connected by the strip plate 2 16. A threaded hole 1 5 is provided on the side wall of one end of the connecting block 1, and a threaded hole 2 13 is provided on the side wall of one end of the connecting block 2 12. Strip holes 7 are provided at the centers of the strip plate 1 6 and the strip plate 2 16, and tooth grooves are provided on the side walls of one end. A hand-tightening bolt 1 8 is threadedly connected in the threaded hole 1 5. A tooth plate 1 9 is rotatably connected to the outer wall of the hand-tightening bolt 1 8. One end of the hand-tightening bolt 1 8 passes through the strip hole 7 and is threadedly connected to the inner wall of the threaded hole 1 5, so that the tooth plate 1 9 engages with the tooth groove on the outer wall of the strip plate 1 6, fixing the two connecting blocks 1. When it is necessary to adjust the distance between the two connecting blocks 1, by flipping the hand-tightening bolt 1 8, the tooth plate 1 9 is separated from the tooth groove, and the connecting block 1 can be moved.

[0027] A hand-tightening bolt 2 17 is threadedly connected in the threaded hole 2 13. A tooth plate 2 18 is rotatably connected to the outer wall of the hand-tightening bolt 2 17. One end of the hand-tightening bolt 2 17 passes through the strip hole 7 and is threadedly connected to the inner wall of the threaded hole 2 13, so that the tooth plate 2 18 engages with the tooth groove on the outer wall of the strip plate 2 16. When moving the connecting block 1, it is necessary to first screw the hand-tightening bolt 2 17 outward to separate the tooth plate 2 18 from the tooth groove, and move the moving block 1 and the connecting block 2 12 simultaneously to change the distance between the two connecting blocks 1 and the two connecting blocks 2 12, facilitating the installation of advertising boards of different lengths.

[0028] In actual use, by rotating the adjusting nut 11, the position of the connecting block 2 12 on the threaded post 10 can be changed, thereby changing the distance between the connecting block 2 12 and the connecting block 1. Thus, advertising boards of different heights can be placed between the connecting block 1 and the connecting block 2 12. Screw the hand-tightening bolt 1 8 and the hand-tightening bolt 2 17 outward, so that the tooth plate 1 9 and the tooth plate 2 18 are separated from the tooth grooves, and move the moving block 1 and the connecting block 2 12 simultaneously to change the distance between the two connecting blocks 1 and the two connecting blocks 2 12, facilitating the installation of advertising boards of different lengths.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
