AI Technical Summary
Traditional guide rails lack a stable guiding fit design between the rail housing and the support structure, which can easily lead to sliding deviation or jamming. In addition, the lack of an anti-sinking support structure results in the rail housing sinking and the reduction of sliding accuracy during long-term use.
A stable guiding structure, anti-sinking support components, and a leveling calibration component are set in the guide rail. The guiding stability and anti-sinking are achieved through the sliding fit between the outer and inner rail shells, the sliding connection between the side plate and the guide groove, the threaded fit between the bracket and the adjusting screw, and the level bubble in the bottom shell.
It achieves stable sliding of the guide rail, avoids sliding deviation and jamming, prevents sinking, and ensures the long-term stability and sliding accuracy of the guide rail.

Abstract
Claims
1. A sinking-preventing guide rail comprising an outer rail shell, an inner rail shell being slidably mounted inside the outer rail shell, characterized in that: Side plates are provided on both sides of the outer rail shell, and the side plates are fixedly connected to the outer rail shell. A back shell is provided on the outside of the side plates. Guide grooves are provided on both sides of the inside of the side plates. Guide strips are provided on both sides of the side plates near the guide grooves, and the guide strips are slidably connected to the guide grooves. A bracket is provided at the bottom of the side plates inside the back shell. An adjusting screw is provided at the bottom of the bracket. The adjusting screw is connected to the back shell by a threaded engagement. A bottom shell is installed on both sides of the lower end of the outer rail shell. An iron shell is provided inside the bottom shell. A spirit level is installed inside the iron shell.
2. The sink resistant track of claim 1, wherein: A magnet is embedded in the upper part of the inner part of the bottom shell and is fixedly connected to the bottom shell. The top of the iron shell is attached to the magnet, and the horizontal bubble is fixedly connected to the iron shell.
3. The sink resistant track of claim 1, wherein: The outer side of the back shell is provided with equidistant anti-slip ridges along the length of the back shell, and the anti-slip ridges are integrally formed with the back shell.
4. The sink resistant track of claim 1, wherein: The outer rail shell has through holes that are evenly distributed along its length, and the through holes are integrally formed with the outer rail shell.
5. The sink resistant track of claim 4, wherein: The through hole is fitted with reinforcing ribs, which are integrally formed with the outer rail shell.
6. The sink resistant track of claim 1, wherein: The back shell has countersunk holes at all four corners, and the countersunk holes are integrally formed with the back shell. The top of the adjusting screw is rotatably connected to the bottom of the bracket.
