Description

Technical Field

[0001] The utility model relates to the technical field of iron nails, in particular to a high-strength anti-loosening iron nail. Background Art

[0002] Iron nails have a flat head on one end and a sharp tip on the other. They are mainly used for fixing or connecting, and can also be used to hang objects. There are many types of iron nails, including common nails, felt nails, cement steel nails, headless nails, gun nails, and coil nails. The surface can be galvanized or copper-plated, and you can choose according to your actual needs.

[0003] When using iron nails to hammer into wooden structures for connection, the wooden structure is not as hard as the concrete wall, and the friction between the iron nails and the wooden structure is not as good as the friction between the iron nails and the concrete wall. It is very likely that the iron nails will fall off during the hanging process, causing inconvenience to daily use. Utility Model Content

[0009] Preferably, the diameter of the auxiliary pin is slightly larger than the distance between the two positioning pins before the movement.

[0010] Preferably, the positioning pin is slidably connected to the hole and has a certain damping.

[0011] Preferably, the upper surface of one end of the positioning pin close to the through slot is designed to be arc-shaped.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model uses a tool to knock the nail cap so that the nail body and the nail head are embedded in the wooden structure, and then a flathead screwdriver is inserted into the flathead notch and rotated clockwise, so that the thread can be embedded in the wooden structure. At this time, the scribing piece will rotate along, and the oblique edge of the scribing piece will cut the wooden structure and insert it into the cut, and then the auxiliary nail is knocked in from the through groove. In the process of the auxiliary nail descending, the lower end of the auxiliary nail contacts the surface of the positioning pin and squeezes the positioning pin, so that the positioning pin extends out of the hole and is embedded in the wooden structure, thereby achieving the effect of auxiliary fixing, improving the connection strength of the iron nail, and further improving the anti-loosening effect.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1 The figure shows a high-strength anti-loosening iron nail, including a nail cap 1, characterized in that: a nail body 2 is fixedly installed on the bottom surface of the nail cap 1, a nail head 3 is installed on the bottom surface of the nail body 2, a through groove 4 is opened on the upper surface of the nail cap 1, an auxiliary nail 5 is slidably connected inside the through groove 4, a scriber 9 is fixedly installed on the outer surface of the nail body 2, and a hole 10 is opened on the outer surface of the nail body 2, and a positioning pin 11 is slidably connected inside the hole 10.

[0022] See also Figure 2In the figure, a thread 6 is provided on the upper end of the outer surface of the nail body 2, and a slot 7 is provided on the top surface of the nail cap 1.

[0023] In this embodiment, by inserting a flat-head screwdriver into the flat-head notch 7 and rotating it clockwise, the thread 6 can be embedded in the wooden structure, thereby improving the connection strength of the nail and preventing it from loosening.

[0024] Working principle: When in use, use a tool to knock the nail cap 1, so that the nail body 2 and the nail head 3 are embedded in the wooden structure, and then use a flathead screwdriver to insert it into the flathead slot 7 and rotate it clockwise to make the thread 6 embedded in the wooden structure. At this time, the scriber 9 will rotate with it, and the beveled edge of the scriber 9 will cut the wooden structure and insert it into the cut. Then, the auxiliary nail 5 will be knocked in from the through slot 4. During the descent, the lower end of the auxiliary nail 5 contacts the surface of the locating pin 11 and squeezes the locating pin 11, so that the locating pin 11 extends from the hole 10 and is embedded in the wooden structure, thereby achieving the effect of auxiliary fixation, improving the connection strength of the iron nail, and further improving the anti-loosening effect.

[0025] Example 2

[0026] See also Figure 1 This embodiment further explains Example 1. In the figure, a notch 8 is provided on the left side of the upper surface of the nail cap 1.

[0027] In this embodiment, by providing the notch 8, it is convenient for the staff to use tools to pry out the nails, thereby achieving the purpose of facilitating disassembly, avoiding the waste of time caused by difficulty in prying out due to over-tight connection or wrong installation position, and improving work efficiency.

[0028] See also Figure 1 In the figure, there are two groups of scribers 9 that are symmetrical to each other, and the scribers 9 are right-angled triangles with sharp blades at the hypotenuse.

[0029] In this embodiment: by providing a scribing piece 9, when the iron nail is driven into the structure and rotated, the oblique edge of the scribing piece 9 will cut the wooden structure and insert it into the cut, thereby achieving a high-strength anti-falling effect, avoiding loosening during use, and improving stability.

[0030] See also Figure 4 In the figure, the diameter of the auxiliary nail 5 is slightly larger than the distance between the two positioning pins 11 before the movement.

[0031] In this embodiment: by providing an auxiliary nail 5, after the iron nail is embedded in the wooden structure, the auxiliary nail 5 is knocked in from the through groove 4. During the descending process, the lower end of the auxiliary nail 5 contacts the surface of the positioning pin 11 and squeezes the positioning pin 11, so that the positioning pin 11 extends out of the hole 10 and is embedded in the wooden structure, thereby achieving the effect of auxiliary fixing and further improving the anti-loosening effect.

[0032] See also Figure 4 In the figure, the positioning pin 11 is slidably connected to the hole 10 and has a certain damping.

[0033] In this embodiment, by setting a sliding connection with a certain damping between the positioning pin 11 and the hole 10, it can be prevented that the positioning pin 11 falls off from the inside of the hole 10 when the nail is not in use, thereby affecting subsequent operations.

[0034] See also Figure 3 In the figure, the upper surface of the end of the positioning pin 11 close to the through slot 4 is designed to be arc-shaped.

[0035] In this embodiment: by designing the upper side of the end of the locating pin 11 to be arc-shaped, the collision force between the two can be reduced when it contacts the bottom of the auxiliary nail 5, thereby avoiding the locating pin 11 from being deformed and unable to function, and making it easier for the locating pin 11 to be embedded in the wooden structure.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include"-"comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process-method-article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process-method-article or device.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
