[0011] Compared with the prior art, the beneficial effects of the utility model are: the promotional stand with an adjustment structure can adjust the height of the promotional stand by moving the relative positions of the first support column and the second support column, so that the promotional stand has an adjustment structure, and the promotional stand is adsorbed on the ground by a suction cup, thereby increasing the contact area between the promotional stand and the ground, enhancing its stability, making it difficult for the promotional stand to collapse, and moving the fixed frame into the slot of the slot, and then limiting the fixed frame by an insert block, thereby facilitating the assembly of the promotional frame.

[0012] 1. The publicity rack with an adjustment structure, if the height of the publicity rack needs to be adjusted, the second bevel gear is rotated by the knob, so that the threaded rod and the second support column are threadedly transmitted, so that the second support column is raised, and finally the height of the publicity rack is adjusted. The publicity rack has an adjustment structure, and the suction cup is used to stably support the publicity rack on the ground, and the stability is good;

[0013] 2. The promotional stand with an adjustable structure moves the insert block and inserts the fixing frame into the slot, and then releases the insert block. The spring then resets and automatically pushes the insert block into the first fixing block, thereby limiting the fixing frame and facilitating quick assembly of the promotional stand.

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1 , Figure 5 and Figure 6 The utility model provides a technical solution: a promotional stand with an adjustment structure, comprising a base 1, a first support column 2, a fixing frame 9 and a second support column 10, wherein suction cups 13 are fixed around the base 1, a first support column 2 is welded on the top of the base 1, a second support column 10 is inserted into the interior of the first support column 2, a threaded rod 4 is arranged inside the second support column 10, a first bevel gear 3 is fixed to the outside of one end of the threaded rod 4 close to the base 1, a second bevel gear 11 is meshedly connected to one side of the first bevel gear 3, and a knob 12 is fixed to one end of the rotating shaft of the second bevel gear 11.

[0023] See attached Figure 1 , Figure 5 and Figure 6 The first bevel gear 3 and the second bevel gear 11 are meshed with each other, the threaded rod 4 is rotationally connected to the first support column 2 through a bearing, the threaded rod 4 is threadedly connected to the second support column 10, the second support column 10 is a regular quadrilateral structure, and the second support column 10 is slidingly connected to the first support column 2.

[0024] During specific implementation, if it is necessary to adjust the height of the publicity rack, the second bevel gear 11 is rotated by the knob 12, so that the second bevel gear 11 and the first bevel gear 3 are meshed and transmitted, and then the first bevel gear 3 drives the threaded rod 4 to rotate, so that the threaded rod 4 and the second support column 10 are threadedly transmitted, so that the second support column 10 moves along the inner wall of the first support column 2. The second support column 10 is a square structure so that it moves along a specified path. The second support column 10 is raised or lowered by the forward and reverse knob 12, and finally the height of the publicity rack is adjusted. The publicity rack is installed with the billboard and placed in the shopping mall. Stepping on the base 1 allows the suction cup 13 to evacuate the air inside, and then adsorb on the ground, and cooperate with the base 1 to increase the contact area between the publicity rack and the ground, and the stability is better.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A card slot 15 is provided on one side of the second support column 10, a fixing frame 9 is arranged inside the card slot 15, a second fixing block 6 is arranged on the top of the fixing frame 9, and a connecting block 14 is arranged inside the second fixing block 6, the second fixing block 6 is fixed to the second support column 10, a spring 7 is abutted on the top of the connecting block 14, and the end of the spring 7 away from the connecting block 14 abuts on the inner wall of the second fixing block 6, an insert block 8 is fixed to the end of the connecting block 14 away from the spring 7, and a first fixing block 5 is sleeved on the outside of the end of the insert block 8 away from the second fixing block 6, and the first fixing block 5 is fixed to the outer wall of the second support column 10.

[0026] During specific implementation, if it is necessary to assemble the promotional rack, first pull the plug block 8, which will drive the connecting block 14 to move along the second fixed block 6, while squeezing the spring 7 to contract, and then move the fixed frame 9 to insert it into the slot 15, and then release the plug block 8 so that the spring 7 loses pressure and rebounds, thereby pushing the plug block 8 into the first fixed block 5 through the connecting block 14, and finally restricting the fixed frame 9, so that the promotional rack can be quickly assembled without the use of bolts or welding.

[0027] To sum up, the billboard is pasted on the fixed frame 9 of the publicity rack and placed in the shopping mall. Its height can be adjusted according to actual conditions. The publicity rack displays the billboard in a conspicuous position to play a publicity role.
