However, the composition of the lifting structure does not consider the overall waterproof and dustproof requirements. As a result, it is easy for moisture and dust to invade into the interior from the assembly gap of its components during use, causing internal gear sets, actuation shafts and other mechanical parts to be affected by moisture and dust and malfunction. In addition to subsequent maintenance problems, At the same time, it also affects the overall service life, and it is necessary to try to solve the improvement.

In view of the lack of water-proof and dust-proof performance of conventional linear actuators, the internal parts are prone to failure and affect the service life. The creators have carried out research and development based on their years of experience and technology in related industries, and then completed this Creative structure of linear actuator.

In order to effectively prevent external moisture and dust from invading the interior of the linear actuator, the original creation is based on the structure, which is mainly to make an integrated tube seat on the side of the base of the linear actuator to insert the tube sleeve of the actuator shaft. Assembled, and a waterproof gasket is placed between the inner end of the pipe sleeve and the pipe seat, and a waterproof gasket is also placed between the outer end of the pipe sleeve and the dust cover, so that the actuator parts assembled inside can be waterproof and dustproof In addition, a motor shield is provided on the outside of the motor assembled on one side of the base, and a waterproof gasket is also placed between the motor shield and the base to provide the motor with waterproof and dust-proof protection, thus achieving its expectations Function of the person.

The innovative structure of the linear actuator in this creation, through the installation of waterproof gaskets between the assembly interfaces of its components, can give an excellent sealing effect, so as to effectively prevent the intrusion of moisture and dust, and prevent the internal base parts from being damaged. Affected by moisture and dust, which can effectively reduce the probability of failure to maintain the normal operation of its functions and extend its service life.
