Rotary elevating mechanism of liquid crystal screen rack for showing car

Abstract

The invention discloses a rotary elevating mechanism of a liquid crystal screen rack for showing car and belongs to the technical field of car show. The showed car comprises a chassis girder of a car frame and a carriage body. The rotary elevating mechanism of the liquid crystal screen rack comprises a fixed box rotating device which is mounted on the chassis girder of the car frame, a fixed box which is connected with the fixed box rotating device, a display screen rack elevating device which is matched with the fixed box, a fixed display screen rack which is corresponding to one side of the display screen rack elevating mechanism, a movable display screen rack which is corresponding to the other side of the display screen rack elevating mechanism, and a pair of movable display screen rack turning and folding devices which is mounted at the side of the fixed display screen rack towards the movable display screen rack, wherein the display screen rack elevating mechanism has sleeve type overlapped structure. The rotary elevating mechanism of the liquid crystal screen rack for showing car is capable of avoiding the directional limits in different angles in showing, enables the display and watching effects to be improved, enables the structure to be simplified, and is capable of representing the display screen rack in double-wide structure in use so that the large screen display requirement is satisfied.

Description

technical field [0001] The invention belongs to the technical field of display vehicles, and in particular relates to a rotating and lifting mechanism for a liquid crystal display frame of a display vehicle. Background technique [0002] Demonstration cars are called mobile advertisements, and their applications are becoming more and more frequent and widespread. The pre-planning and / or real-time display of the event, such as the art department sending art to the countryside for display, and the medical, health and epidemic prevention department's tour presentation and display, and so on. [0003] In the published Chinese patent literature, it can be seen that all the technical information about the liquid crystal display frame of the display car is typical, such as the "Liquid Crystal Display Stand Lifting Mechanism of the Display Car" recommended by the invention patent authorization announcement number CN101409034B, one of the achievements of this patent solution The adv...

AI Technical Summary

Problems solved by technology

But this patent scheme has the following shortcomings: one, because the liquid crystal display frame only has a lifting function and does not have a rotary function, so the display effect is affected; device) and a pair of lifting frames, so the structure is complicated, especially, once the lifting of a pair of lifting devices is out of sync, it will damage the LCD frame; third, because the rising height of the LCD frame is only for lifting The height of the gantry of the device, and thus the lifting height is restricted, which is not enough to reflect the desired display effect to a certain extent. However, if the height of the gantry is simply increased, then it will be restricted by the height of the car's compartment itself. Restrictions, that is, the height of the door frame is not allowed to exceed the height of the
