Description

Technical Field

[0001] The utility model relates to the technical field of conical sealing screws, in particular to a conical sealing screw with a moisture-proof cover. Background Technique

[0002] In the fields of mechanical assembly and construction, screws, as common fasteners, are widely used for the connection and fixation of various equipment and structures. However, in some special environments, especially in humid and corrosive environments, traditional screws are prone to problems such as poor sealing and moisture and rust, which affect the connection effect and service life of the screws. In a humid environment, water vapor and pollutants outside the screw are easy to penetrate into the interior through the threads, resulting in internal corrosion or rust, and ultimately leading to the failure of the fastener. In addition, ordinary screws lack effective protection design and have poor sealing performance. When exposed to the external environment for a long time, it is easy to reduce the use efficiency of the equipment, and even requires frequent replacement or maintenance. In actual use, traditional conical sealing screws often have poor sealing effect due to imperfect sealing structure design. Especially in a humid environment, they are vulnerable to moisture intrusion, causing damage to the interior of the screw, reducing the service life of the conical screw, and having poor practicability, so improvement is needed.
