A combination bolt with anti-loosening and corrosion resistance

Abstract

The present invention provides a lock - preventing and corrosion - resistant combined bolt, which relates to the field of bolts and includes: a top piece. The interior of the top piece is of a cylindrical structure. At the top end inside the top piece, there is a top bin. The interior of the top bin is of a funnel - shaped structure. The top bin is communicated with the interior of the top piece, and there is a partition board at the connection position between the top bin and the top piece. When in use, after the main body is installed, the top piece is controlled to be installed outside the main body, so that the sealing plate is in sealed contact with the installation position, and the top piece is located outside the main body for protection, improving the corrosion - resistant effect. At the same time, after the top piece is tightened, the top end of the main body pushes the moving rod through the round plate, so that the moving rod drives the cutting piece to move, and the cutting piece cuts the partition board, and anti - corrosion coating is automatically added to the gap and outside the main body, improving the anti - corrosion effect. This solves the problems that the existing combined bolts are prone to corrosion during use, lack corrosion - resistant structures, and cannot automatically control the discharge of corrosion - resistant liquid materials after the installation of the corrosion - resistant structures.

[0009] Beneficial effects

[0010] 1. By arranging the pressing plate and the contact part, when the device is in use, the pressing plate uses its own elasticity to push the contact block. At the same time, after the moving part receives the power of the spring, it supports and pushes the pressing plate, thereby improving the elasticity of the pressing plate. At the same time, the moving part itself installs the contact part, so that the contact part can be stressed together with the contact block and fixedly contact the installation position. After the combination bolt is tightened, the fixing effect can be improved, thereby preventing the bolt from loosening;

[0011] 2. By setting the insert, when the device is in use, after the inner part is installed together with the main body, the insert can be forced to insert into the installation gap. At the same time, the inner part bends the insert made of elastic metal material through the clamping groove, and the support plate made of elastic metal material continuously pushes the inner part, so that the insert is continuously inserted into the connection gap, thereby improving the fixed connection effect and preventing the main body from loosening.

[0012] 3. By setting the top bin and the sealing plate, when the device is in use, after the main body is installed, the top part can be controlled to be installed outside the main body, so that the sealing plate can be in sealed contact with the installation position, and the top part can be used for protection outside the main body, thereby improving the corrosion resistance effect. At the same time, after the top part is tightened, the top end of the main body can push the moving rod through the round plate, so that the moving rod drives the cutting part to move, and the cutting part can cut the partition plate, so that the liquid anti-corrosion coating inside the top bin can seep downward under the action of gravity, and then be in the gap and outside the main body, thereby automatically adding the anti-corrosion coating and improving the anti-corrosion effect.
