Abstract

The present invention relates to the field of photographing equipments and discloses a waterproof stabilizer. The waterproof stabilizer has a fastening assembly, a rotary assembly and a waterproof assembly. The rotary assembly has a first motor, a second motor and a third motor, a first connecting arm piece and a second connecting arm piece. The first motor, the second motor and the third motor are spatially distributed orthogonally. The waterproof assembly has a first seal ring, a second seal ring, a third seal ring, a fourth seal ring, a first waterproof plug, a second waterproof plug and a third waterproof plug. Multiple said seal rings and said waterproof plug are respectively arranged between structural parts or between connecting parts to reinforce the sealability of the waterproof stabilizer, which enables the waterproof stabilizer to be waterproof and functionally applicable in dampness or when contacting water.
