[0025] Such as Figures 1-4As shown in the figure, the utility model provides an advertising display rack facilitating the replacement of an advertising board, which comprises a base 1 and a support rod 2 erected on the base 1. An upper mounting plate 3 is arranged at the top of the support rod 2, and a lower mounting plate 4 is movably arranged at a position below the upper mounting plate 3 on the outer wall of the support rod 2. A limiting sleeve 5 is sleeved on the outer wall of the support rod 2. A column 6 is arranged on the end face of the limiting sleeve 5 in contact with the lower mounting plate 4. As the lower mounting plate 4 fits with the limiting sleeve 5, the column 6 is inserted into a groove arranged on the lower mounting plate 4. And a connecting rib 7 is arranged in the inner direction of the two support rods 2. The two ends of the connecting rib 7 are respectively fixedly connected with the lower mounting plate 4 and the limiting sleeve 5 through bolts, so as to assemble the lower mounting plate 4 and the limiting sleeve 5 into a whole, and enable the lower mounting plate 4 to move up and down along the length direction of the support rod 2 along with the limiting sleeve 5. A first locking member 8 is arranged on the limiting sleeve 5. The first locking member 8 is in threaded connection with a threaded hole arranged on the limiting sleeve 5. After determining the use height of the lower mounting plate 4, the first locking member 8 is screwed clockwise, so that the front end of the first locking member 8 abuts against the outer wall of the support rod 2, for fixing the mounting height between the upper mounting plate 3 and the lower mounting plate 4. In order to improve the friction force between the first locking member 8 and the outer wall of the support rod 2, a rubber gasket is arranged at the end of the first locking member 8 in contact with the support rod 2. A first mounting groove 9 is arranged on the lower end face of the upper mounting plate 3 along its length direction. A second mounting groove 10 is arranged at the position of the lower mounting plate 4 opposite to the first mounting groove 9. After adjusting the mounting height between the upper mounting plate 3 and the lower mounting plate 4 according to the height of the advertising board 100, the upper and lower ends of the advertising board 100 are respectively inserted into the first mounting groove 9 and the second mounting groove 10 from the side. Through this structure, the mounting height between the upper mounting plate 3 and the lower mounting plate 4 can be adjusted to meet the different heights of the advertising board 100, and the overall practicability is improved.

[0026] As Figures 2-4 shown, a positioning assembly 11 is arranged at the middle position of the lower mounting plate 4. The positioning assembly 11 includes a fixed seat 1101, a positioning plate 1102 and a spring 1103. The fixed seat 1101 is detachably assembled in a fixed groove arranged on the lower mounting plate 4. The spring 1103 is arranged in the fixed seat 1101, and the other end of the spring 1103 is connected with the positioning plate 1102, so that the positioning plate 1102 is inserted into a card slot of the advertising board 100 under the action of the spring 1103, thereby fixing the advertising board 100 between the upper mounting plate 3 and the lower mounting plate 4, thus simplifying the disassembly and assembly steps of the advertising board 100 on the advertising display rack and facilitating the operation of personnel.

[0027] Further, in order to facilitate the disassembly and assembly of the advertising board 100, guiding inclined surfaces 12 are provided on both sides of the positioning plate 1102 in the pushing and pulling directions of the advertising board 100. When installing the advertising board 100, the advertising board 100 first contacts the guiding inclined surfaces 12 to facilitate the continuous pushing of the advertising board 100. The advertising board 100 presses the positioning plate 1102 downward. As the advertising board 100 is pushed in, the positioning plate 1102 will be squeezed into the fixing seat 1101. When the card slot of the advertising board 100 moves directly above the positioning plate 1102, the positioning plate 1102 is inserted into the card slot under the action of the spring 1103, thereby fixing the position of the advertising board 100. At the same time, a plurality of second locking members 13 are provided along the length direction of the lower mounting plate 4. The second locking members 13 are connected to the threaded holes provided on the lower mounting plate 4. After the advertising board 100 is installed on the upper mounting plate 3 and the lower mounting plate 4, the second locking members 13 are rotated clockwise so that the front end portions of the second locking members 13 extend into the second mounting groove 10 and abut against the advertising board 100, thereby improving the stability of the position of the advertising board 100 after installation. When replacing the advertising board 100, a deformation force greater than that of the spring 1103 is used to pull the advertising board 100 outwards in the reverse direction. The guiding inclined surfaces 12 cause the positioning plate 1102 to be compressed into the fixing seat 1101 under force, so as to facilitate the pulling out of the advertising board 100. In order to improve the stability of the positioning plate 1102 during the lifting movement, guiding ribs 14 vertically downwardly provided on the guiding inclined surfaces 12 are slidably engaged with guiding grooves 15 provided on the inner wall of the fixing seat 1101, so that the positioning plate 1102 moves vertically up and down.

[0028] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
