Description

Technical Field

[0001] The utility model belongs to the field of telescopic stand devices, in particular to an anti-deviation telescopic stand device. Background Art

[0002] The telescopic stand device is a device widely used in various stadiums, performance venues, conference halls and other places. However, there are still some disadvantages in the existing telescopic stands, one of the most obvious disadvantages of which is the lack of correction effect.

[0003] The telescopic stand is prone to deviation during the extension process, which may lead to insufficient utilization of the space inside the venue, affect the audience's viewing experience, and even cause safety hazards. If the telescopic stand does not have a deviation correction effect, this problem cannot be effectively solved, which brings great trouble to the venue management;

[0004] In addition, there are safety hazards in telescopic stands without a correction effect. Telescopic stands need to bear a large weight and force when extending and retracting. If there is no correction effect, it may cause the seat part to deform or swing, thus affecting the safety of the audience. This safety hazard is more obvious in the case of a large flow of people and dense audiences.

[0005] In addition, the telescopic stand without the correction effect will increase the difficulty of venue management. In the absence of the correction effect, the venue managers need to constantly maintain and adjust the position and angle of the telescopic stand to ensure that it does not deviate. This not only increases the workload of the managers, but also affects the efficiency and effectiveness of venue management. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content
