Description

Gecko nail structure

This creation is about a gecko nail locked on a wall such as gypsum board, especially the gecko nail will not deform during the drilling process. After the screw is locked into the gecko nail, the deformed gecko nail structure will split.

According to the current, the object is to be nailed on the wall of the gypsum board. Most of them will be drilled on the wall with a special gecko nail for gypsum board, and then locked with a screw, then the screw will open the gecko nail. The locking end of the gecko nail is split into two feet so as to be fixed on the wall surface of the sheet-shaped gypsum board.

Expansion screws are introduced on the market, such as the "Anchor" invention patent of US Patent Publication No. US7762751. The Anchor is first drilled on the wall, and then locked into the gecko nail with a screw to allow the screw to open the gecko nail. The two legs 224,226 are used to split the two legs so as to be fixed on the wall of the gypsum plasterboard. However, the design of the two legs 224,226 is not partially penetrated by the end only to achieve the purpose of connection. This design is easy. The twisting force between the two feet of 224,226 during the installation of the gecko nail on the wall surface caused the two feet to produce an unexpected separation. When the two feet produced an unexpected separation, they could not be successfully drilled into the gypsum board, making the gecko nail The effect is lost, but only another gecko nail is used for drilling, or the end part of the unpenetrated part is lengthened. However, when the unpenetrated part is lengthened and the screw is locked into the gecko nail, the unpenetrated part cannot be smoothly disconnected. The lengthening of the part made it impossible for the two legs 224,226 to be stretched, thereby losing the effect of fixing the thin plasterboard wall surface.

In view of the familiarity of the gecko nails, the author often has two feet disconnected during the installation of the gypsum board, or when the screws are locked into the gecko nails after the gypsum board is installed, the two feet cannot be used. Successfully disconnected, this kind of action that can not reach 100% of the expected, so that many gecko nails must be wasted. Based on the ideas of Nai Si and creation, after many discussions and trials of sample experiments, and multiple amendments and improvements, this creation was launched. .

This creation provides a gecko nail structure, including: a gecko nail, the gecko nail includes: a first end and a second end opposite to the first end, the first end and the second end have a central axis, a A shaft extending from the first end to the second end. The shaft and the first end are provided with a head larger than the outer diameter of the shaft, and an end of the head is provided with a deep tool groove. The tool slot can provide a driving tool for turning or screwing in. The outer surface of the shaft is provided with a thread from the first end to the second end. The second end of the shaft is tapered. A drill point, and a penetrating crack hole is cut on the rod body, and the penetrating hole penetrates the tool slot, so that the rod body is divided into a first leg and a second leg with the crack hole as a boundary, and the crack hole is formed by the rod. The body section extends to the lower section of the shaft, and the crack is divided into a first section, a second section and a third section, the first section is close to the first end and passes through the central axis, and the second section is connected to the first section and It is bent and deformed, so that the second section has a protruding portion formed on the opposite side of the first leg and the second leg respectively. The third segment is connected to the second segment and extends obliquely to the side of the second leg, so that the first leg and the second leg are unequal in length, and there is an uncut connection at the end of the third segment. A segment connects the first leg and the second leg, and a thin piece of connecting strip is connected between the first leg and the second leg in the third segment, the connection is provided with a first thickness T1, The connecting section 176 has a second thickness T2. The first thickness T1 of the connecting band is one third of the second thickness T2 of the connecting section 176, and the first thickness T1 does not exceed 3 mm.

The main purpose of this creative gecko nail structure is that when the gecko nail is drilled into the hollow gypsum board, the reverse torsion between the first leg and the second leg is simultaneously connected by the connecting section and the entire length of the connecting belt. Because the torsion is equally divided over the longer total length of the connection, it can be ensured that the gecko nail completely locks the hollow gypsum board, and the first leg and the second leg are completely disconnected unexpectedly; When the screw is locked in the tool slot of the gecko nail, the shaft is expanded and expanded, and the connection band will only be torn from the thinnest front end by the thickness, and then gradually enlarged and finally the entire connection band is torn apart. The connection section at the end can therefore easily disconnect the connection band and the connection section, and has the advantages that the gecko nail can withstand large torque and the first leg and the second leg can be easily disconnected.
