Fixing principle of Wall plug

Fixing principle of Wall plug

Generally speaking, Wall plug is a metal Wall plug, and the fixation of Wall plug is to use wedge slope to promote expansion to generate friction and wrapping force, so as to achieve the fixed effect. One end of the screw is threaded and the other end has a taper. A piece of iron sheet (some are steel pipes) is wrapped on the outside, and half of the iron sheet cylinder (steel pipe) has several notches. They are inserted into the holes made on the wall together, and then the nut is locked. The nut pulls the screw outward, pulling the taper into the iron sheet cylinder. The iron sheet cylinder is expanded and tightly fixed to the wall, usually used for fastening protective fences, awnings, air conditioners, and other materials on cement, bricks, etc. But its fixation is not very reliable, and if there is significant vibration under the load, it may become loose, so it is not recommended for installing ceiling fans, etc.

Advantages:

1. Wide applicability. As long as the thread size of the male part meets, it is suitable for any form of anchor bolt head type.

2. Construction method selection. It can be preset at designated locations according to demand, or drilled or installed in a single construction site, with the same function and effectiveness.

3. High construction success rate. There is no problem with depth attachment and drilling inclination, and the construction completion rate is 100%.

4. High pitched pull design. Full tooth taper expansion special inverted hook design.

5. Locking and anti loosening effect. The special design of full tooth taper expansion utilizes the reverse thrust effect to urgently lock the workpiece.

6. Improve design thinking. Short and concise, suitable for matching with all commercially available screws, DIY, and the most satisfactory construction optional parts.

7. Ensure anchor bolt expansion. Metal plate pressing product, patented full tooth taper expansion design, strong gripping ability without idling, without the need for professional construction skills.

8. Dispose of without any trouble. As long as the anchor bolt workpiece is withdrawn and the filling agent is applied to restore the plane, there is no cutting trouble and collision risk of protruding objects.
