Description

Novel expansion nail

Technical Field

The utility model relates to the technical field of expansion nails, in particular to a novel expansion nail.

Background

The expansion nail is composed of a screw rod, an expansion pipe and the like. The tail part of the screw is in a conical shape: the inner diameter of the cone is larger than the inner diameter of the expansion pipe. As the nut is tightened, the screw moves outwardly. By axial displacement of the thread. The conical part is used for moving, so that a large positive pressure is formed on the periphery of the expansion pipe, and the angle of the cone is small, so that friction self-locking is formed among the wall body, the expansion pipe and the cone, and the fixing effect is achieved. The expansion nail achieves the fixing effect by utilizing the friction force generated by the expansion caused by the wedge-shaped slope. The fastening device is generally used for fastening guard rails, rain canopies, air conditioners and the like on materials such as cement, foam bricks, brickwork, hollow bricks and the like.

However, the existing expansion nail is not very reliable in fixation, the connection between the sleeve and the hole wall is not tight enough, and only one group of sleeves are arranged in the expansion nail, so that once the sleeves are broken, the expansion nail loses the effect, and is likely to loosen or fall off, and the service life is shortened.
