Description

Actuator worm sealing structure Technical Field The utility model relates to the technical field of automobile parts, in particular to an actuator worm sealing structure. Background The invisible door handle actuator is generally used on an automobile invisible door handle, is loaded on the automobile door handle, drives an actuating rod to do repeated linear motion through forward rotation or reverse rotation of an output shaft of a motor, and achieves opening and closing actions of the invisible door handle, so that the limiting surface formed on the actuating rod and a matching surface matched with the limiting surface in a shell are fully utilized to achieve the functions of stopping rotation and guiding linear motion, but the conventional invisible door handle actuator has the following defects when in use: The telescopic worm inside the existing door handle actuator in the market is sealed by adopting a simple sealing ring, the sealing mode is poor in effect, external air is easy to enter the actuator shell through the worm and the sealing ring, joints inside the actuator shell are polluted, and the service life of the inner structure of the actuator shell is influenced. Disclosure of Invention The utility model provides an actuator worm sealing structure, which aims to solve the problems in the background technology. In order to achieve the purpose, the technical scheme is that the actuator worm sealing structure comprises a retainer ring, wherein the retainer ring is sleeved on a worm and comprises a supporting framework and sealing rings coated outside the supporting framework, the number of sealing main lips of the sealing rings is not less than two, and springs corresponding to the two sealing main lips are sleeved on two sides of the sealing rings respectively. Furthermore, the inner ring of the sealing ring is also provided with at least two sealing auxiliary lips, and the two sealing auxiliary lips respectively correspond to the two sealing main lips. Furthermore, both sides of the sealing ring are provided with avoidance notches. Furthermore, the inside of dodging the breach is provided with the annular, the inside of annular is located in the movable cover of spring. Further, the outer rings of the supporting framework and the sealing ring are provided with positioning protrusions. Further, the worm is movably arranged in the actuator shell, and a sealing groove for installing the check ring is arranged in the actuator shell. Further, positioning grooves are formed in two sides of the sealing groove, and one end of each positioning protrusion extends to the inside of each positioning groove. Further, one end of the worm penetrates through the check ring and extends to the outside of the actuator shell, and the other end of the worm is provided with a double-head worm through the push-out screw.
