The invention discloses a camera support pressurization
system. The camera support pressurization
system comprises a support body, wherein a plurality of telescopic supporting legs are arranged on thesupport body; the camera support pressurization
system is characterized in that a pressurization cavity is arranged at the lower part of the support, one side of the pressurization cavity is providedwith a pneumatic pump, and the pneumatic pump is connected to the upper part of the pressurization cavity; the pressurization cavity comprises a plurality of connecting pipes which are arranged at the bottom and are connected to an inner
pipe cavity of the supporting legs, a magnetic control valve is arranged on the openings of the connecting pipes, and one side of the magnetic control valve is further provided with a
pressure sensor; and a main switch of the pneumatic pump, the magnetic control valve and the
pressure sensor is arranged at the hinged position of the supporting legs, the mainswitch is turned on when the supporting legs are unfolded towards the periphery, and the main switch is turned off when the supporting legs are folded towards the center. According to the camera support pressurization system, the supporting legs are pressurized and stretched through the pneumatic pump, when the supporting legs meet resistance in the stretching process, the
pressure sensor measuresthe pressure change, the magnetic control valve is directly or indirectly controlled to
cut off the air pressure from the pressurization cavity, so that the supporting legs can be stretched and keptin an stretched state; and the supporting legs do not need to be touched manually, and are automatically adjusted according to the contact surface, so that time and labor are saved, and use is convenient and fast.
