Description

Technical Field

[0001] The utility model relates to the technical field of through-wall screw rods, in particular to a through-wall screw rod with good adaptability. Background Art

[0002] A through-wall screw is a connector used to penetrate a wall or other similar structures, and is usually used to install, fix or support various equipment, components or devices. Publication No. CN220117757U discloses a through-wall screw, comprising: a screw body, with external threads at both ends; a nut, with a fixing structure on its outer wall, and an internal thread matched with the external thread on its inner wall, wherein the fixing structure abuts against the template; wherein the screw body passes through the templates oppositely arranged on both sides of the wall, and is connected to the nut through the external thread and the internal thread; and the nut is fixed to the templates oppositely arranged on both sides of the wall through the fixing structure. By adopting this through-wall screw, a solid screw body is provided to replace the traditional through-wall screw and plastic pipe, thereby eliminating the operation of sealing the plastic pipe after the construction is completed, thereby simplifying the operation process and improving work efficiency. However, the length of this type of through-wall screw is always fixed. When facing a thick wall, this type of through-wall screw cannot penetrate the wall. At this time, it is necessary to replace it with a longer through-wall screw. The adaptability is low and the length cannot be adjusted, so it needs to be improved. Utility Model Content
