Abstract

The invention relates to an antitheft exhibition stand, in particular to an air pressure type intelligent antitheft exhibition stand. A pneumatic system is arranged on a base. The upper end of a piston rod of a cylinder is connected with a connecting base plate which is connected with a connecting end cover. The lower end of a drive rod runs through the connecting end cover to be arranged on the connecting base plate. A direct current motor is fixed on the connecting end cover. A small gear is arranged on an output shaft of the direct current motor, and is meshed with a large gear arranged on the drive rod. The upper end of the drive rod runs through a hole on a bottom plate of an exhibition stand box, and is extended into the exhibition stand box and connected with an exhibition plate. A rubber gasket is arranged on the exhibition plate. Electrodes of an electric field sensor are uniformly arranged on the exhibition plate on the periphery of the rubber gasket. A photoelectric proximity switch is arranged in a central hole of the rubber gasket. The exhibition stand box is connected with the base by struts. A movable flashboard mechanism is arranged on the inner side of a top plate of the exhibition stand box. Vibration sensors are arranged on the four inner lateral surfaces of the exhibition stand box. The exhibition stand has improved safety performance, and functions in automatically protecting an exhibit.

Description

technical field [0001] The invention relates to an anti-theft booth, in particular to a pneumatic intelligent anti-theft booth. Background technique [0002] At present, there are more and more buildings such as museums, exhibition centers, and exhibition halls, and the requirements for booths are also getting higher and higher. Most of the existing booths are equipped with glass windows on a fixed base. The disadvantage of this type of booth is that it cannot be moved, and there is no anti-theft facility. Even if there is an anti-theft facility, it can only send an alarm signal without automatic protection. When a dangerous situation occurs, the alarm can only be sounded, but the exhibits cannot be protected, and the exhibits are still in a dangerous situation. Contents of the invention [0003] Aiming at the problems existing in the current booths, the present invention provides a pneumatic intelligent anti-theft booth, which solves the problem that the booth cannot aut...
