Description

Gecko nail structure

The present invention relates to a gecko nail that is locked on a wall such as gypsum board, and particularly refers to a gecko nail structure in which the gecko nail will not be deformed during the drilling process, and the gecko nail will be split and deformed after the screw is then locked into the gecko nail.

Press, at present, to hang objects on the wall of the gypsum board, most of them use a gecko nail special for gypsum board to drill on the wall first, and then lock the gecko nail with a screw, so that the screw can open the gecko nail. Split the locking end of the gecko nail into two legs to fix it on the sheet-like gypsum board wall.

Expansion screws are available in the market, such as the "Anchor" invention patent of US Patent Publication No. US7762751. The anchor is drilled on the wall first, and then a screw is locked into the anchor to make the screw open the anchor. The two legs 224,226 are split to be fixed on the sheet-like gypsum board wall. However, the two legs 224,226 of this design are only partially penetrated at the ends to achieve the purpose of connection. This design is easy The twisting force between the two legs 224,226 during the process of drilling the gecko nail on the wall caused unexpected separation of the two legs. When the two legs were unexpectedly separated, the gecko nail could not be successfully drilled into the gypsum board. If the effect is lost, the only way to use another gecko nail for drilling, or to lengthen the partially non-penetrated part of the end. However, when the non-penetrated portion is lengthened and the screw is locked into the gecko nail, the non-penetrated portion cannot be disconnected smoothly. The lengthening of the part prevents the two legs 224,226 from being stretched, and thus loses the function of fixing to the sheet-like gypsum board wall.

In view of the conventional gecko nails, it often happens that the two feet are disconnected during the process of drilling into the gypsum board, or when the screws are locked into the gecko nail after drilling into the gypsum board, the two feet cannot Smoothly disconnected, this kind of action cannot achieve the expected 100%, so that a lot of gecko nails must be wasted, so the idea of thinking and creation, after many discussions, trial sample tests, and many modifications and improvements, the present invention .

The shaft 11 is gradually changed from the first end 101 to a cylindrical shape and extends to the second end 102. The shaft 11 and the first end 101 are set larger than The head 12 of the outer diameter of the shaft 11 is provided with a deep tool slot 121 at the end of the head 12, and the tool slot 121 can provide a driving tool to penetrate and rotate or the screw 20 to lock in. The tool slot 121 is A cross square hole or a Pozi-shaped hole can be driven by a variety of forms. The outer surface of the shaft 11 is provided with a first thread 13 from the first end 101 to the second end 102, and the first thread 13 is a positive thread type. , And the first thread 13 close to the first end 101 is a deep thread 131 with a high tooth depth, the first thread 13 close to the second end 102 is a shallow thread 132 with a shallow tooth depth, and the shaft 11 is close to the second end A section of the outer diameter of 102 is provided with a plurality of cutting grooves 14 extending from the first end 101 to the second end 102, and the cutting groove 14 and the shallow thread 132 are in the same section position, The second end 102 of the shaft 11 is configured as a taper-shaped drill tip 15, and a second thread 16 is provided on the outer surface of the drill tip 15. The second thread 16 is a reverse thread type and is connected to the first thread. The shallow threads 132 of a thread 13 are staggered, and the first thread 13 is closest to the first end 101 to provide an anti-rotation surface 133.

In addition, a through hole 17 is cut in the shaft 11, and the hole 17 penetrates the tool slot 121, so that the shaft 11 is divided into a first leg 18 and a second leg 19 with the slit 17 as the boundary. The split hole 17 extends from the upper section of the shaft 11 to the lower section of the shaft 11, and the split hole 17 is divided into a first section 171, a second section 172, and a third section 173. The first section 171 is close to the first end 101 and Through the central axis 103, the second section 172 is connected to the first section 171 and formed into a curved shape, so that the second section 172 is formed with a protrusion on the opposite side of the first leg 18 and the second leg 19 The third section 173 is connected to the second section 172 and extends obliquely toward the second leg 19, so that the first leg 18 and the second leg 19 have unequal lengths. The third section There is an uncut connecting section 176 at the end of 173 connecting the first leg 18 and the second leg 19, and a sheet-shaped connecting strap 177 in the third section 173 connects the first leg 18 and the second leg. Between the two legs 19, the connection has a first thickness T1, the connection section 176 has a second thickness T2, and the first thickness T1 of the connection band is one third of the second thickness T2 of the connection section 176. At the same time, the first thickness T1 does not exceed 4mm, and the first thickness is preferably between 1.2mm and 0.4mm, and is located outside the first leg 18 and the second leg 19 near the head 12. Each is provided with a bending groove 181, 191.

First, from the sixth, seventh and eighth diagrams, the gecko nail 10 is drilled in from the outside of a hollow plasterboard 30. When nailing, the gecko nail 10 is nailed in with the drill point 15 The rapid rotation enables the shallow thread 132 of the first thread 13 to be quickly brought in, and at the same time the second thread 16 produces a sharp cutting, cuts off excessive plaster powder and quickly drills in, and uses the reverse thread pattern of the second thread 16 Squeeze the gypsum powder inward, so that the hole will not become too large and the hole can be relatively complete. After a section of drilling, the second thread 16 loses its effect, and the cutting groove 14 is used to more effectively remove the excess gypsum and contain it. Put part of the gypsum powder, and make the dug hole flat and straighten out the hole so that the hole can be very flat and not too large, so that the large deep thread 131 of the first thread 13 continues to be screwed in by twisting. Until the shaft 11 is completely submerged into the hollow gypsum board 30 and the head 12 is attached to the hollow gypsum board 30. When the shaft 11 is screwed in, the first leg 18 and the second leg 19 will produce a reverse twisting pull. If only the connecting section 176 is connected, it is difficult to withstand the twisting force. Using the strip-like characteristic of the connecting belt 177, the whole connecting belt 177 and the connecting section 176 can bear and increase the twisting and pulling between the first leg 18 and the second leg 19, so that the gecko nail 10 is When the hollow plasterboard 30 is completely locked, the first leg 18 and the second leg 19 will not be unexpectedly separated, opened or broken. Once the first leg 18 and the second leg 19 are generated Unexpected separation, the gecko nail 10 cannot be locked into the hollow plasterboard 30.

Then, as shown in the eighth, ninth and tenth figures, the screw 20 is locked into the tool slot 121, the screw 20 will enter along the tool slot 121 and the crack hole 17, and use the screw 20 pushes against the protrusion 174, 175 to gradually expand the shaft 11, so that the first leg 18 and the second leg 19 gradually separate. When the expansion area reaches the connecting belt 177, the connecting belt 177 is a thin sheet. Therefore, when the shaft 11 is stretched, it will only be torn by the thinnest front end of the connecting belt 177, and then gradually expand and finally tear the whole connecting belt 177 and the connecting section 176 at the end, and finally by the tenth As shown in the figure, when the connecting band 177 and the connecting section 176 are completely broken, the first leg 18 and the second leg 19 will be expanded outwards by the bending grooves 181, 191 respectively to reach the inside Fixed.

From the structure of the above specific embodiment, the following benefits can be obtained: when the gecko nail 10 is drilled in from the outside of the hollow plasterboard 30, the first leg 18 and the second leg 19 will be reversely twisted Pull, at this time, the torsion force between the first leg 18 and the second leg 19 is simultaneously connected by the entire length of the connecting section 176 and the connecting belt 177. As shown in the fifth figure, the total connecting length L bears the torsion force, because the torsion force is equally divided The longer total length L of the connection can ensure that when the gecko nail 10 is locked into the hollow gypsum board 30, the first leg 18 and the second leg 19 are completely free from unexpected separation and disconnection; When the screw 20 is locked into the tool slot 121 of the gecko nail 10, the shaft 11 is expanded and the connecting strap 177 is only torn from the thinnest front end at the thickness T, and then gradually expanded. Finally, the entire connecting strap 177 and the connecting section 176 at the end are torn apart, so that the connecting strap 177 and the connecting section 176 can be easily disconnected.
