Description

Technical Field

[0001] The utility model belongs to the field of exhibition stand devices, and in particular relates to an exhibition stand device with an anti-dumping structure. Background Art

[0002] Exhibition is the abbreviation of collective commercial or non-commercial activities such as conferences, exhibitions, and large-scale events. Its conceptual connotation refers to a mass social activity in which many people gather together in a certain geographical space to transmit and exchange information regularly or irregularly, institutionally or non-institutionally. The World Expo is the most typical exhibition activity. At present, the domestic exhibition industry chain is quite complete, and booths are often needed to display items in exhibitions.

[0003] A Chinese patent with publication number CN219680230U discloses an anti-dumping structure exhibition stand, including a counterweight base and a display stand. The display stand is installed above the counterweight base, and a lifting component is installed between the counterweight base and the display stand. The display height of the display stand can be adjusted up and down by using the lifting component. Reinforcement components are installed on the side walls around the counterweight base, and the counterweight base can be laterally supported by means of the reinforcement components. The utility model has a plurality of counterweight blocks hidden and withdrawn on the counterweight base, which is convenient for the subsequent individual removal and replacement of the counterweight blocks. With the cooperation of the reinforcing components, the side walls around the counterweight base are supported in an inclined manner by the reinforcing components, which further enhances the stability of the counterweight base and avoids the problem of the display stand tipping over. At the same time, with the assistance of the lifting components, it is convenient to dynamically adjust the display height of the display stand, which can adapt to different display environments and has strong adaptability. The anti-tipping structure exhibition stand in this application needs to rotate and unfold multiple adjustment platforms one by one, and then rotate the No. 2 threaded rod to drive the anti-slip rod to support the bottom surface. It is time-consuming and labor-intensive to adjust the anti-tipping structure, which makes it time-consuming and labor-intensive to place the exhibition stand stably.

[0004] In view of this, the present utility model is proposed. Utility Model Content
