Product Information：
Expansion Nail is a kind of Sanitary Accessory that uses the friction force generated by the expansion caused by the wedge inclination to achieve a fixed effect.
Expansion Nail is composed of screw and expansion pipe. From the material, it is divided into metal expansion nails and plastic expansion nails, from the installation method into screw-in expansion nails and percussion expansion nails.
Product Features:
Expansion Nail is composed of screw and expansion pipe. The screw tail is conical: the inner diameter of the cone is larger than the inner diameter of the expansion pipe. When the nut is tightened, the screw moves outward. Through the axial movement of the thread. Use the cone part to move, and then form a great positive pressure on the outer circumference of the expansion pipe, and the angle of the cone is small, so that friction self-locking is formed between the wall, the expansion pipe and the cone, thereby achieving a fixed effect. Expansion nails use the friction force generated by the expansion caused by the inclination of the wedge to achieve a fixed effect. It is generally used to fasten protective fences, awnings, air conditioners, etc. on cement, bricks and other materials.
Instructions:
Prefabricate holes of appropriate expansion nail size in the connecting base; implant the expansion nails into it; expand the sleeve to make it firmly fixed to the base; the diameter of the drill hole cannot be larger than the diameter of the expansion pipe.
Most expansion nails are detachable after being fixed, but when they are disassembled and reassembled, the fixing reliability will decrease to varying degrees, and sometimes they may even fail. Reason: The deformability of the casing is reduced, and the prefabricated hole becomes larger due to disassembly. Treatment method: Replace the same type of casing, replace the large-size casing, and re-enlarge the prefabricated hole if necessary.
