[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Embodiment

[0017] Please refer to Figure 1-2The utility model provides the following technical solutions: A reinforced steel nail, comprising a nail head 1 and a nail body. The nail body is mainly composed of a nail rod 2, one end of which is tightly connected to the nail head 1, and the other end is provided with a sharp nail tip 3 to ensure that it can be firmly embedded in an object. The upper surface of the nail rod 1 is evenly provided with anti-recession teeth 4, which are distributed in a staggered manner, aiming to enhance the anti-recession reinforcement effect of the steel nail and increase the binding force of the nail hole. The thickness of the anti-recession teeth 4 gradually decreases from the root to the end, ensuring the strength of the anti-recession teeth 4; the diameter of the rod with the anti-recession teeth 4 at the top of the nail rod 2 is slightly larger than the diameter of the rod with the ribs 5 at the bottom of the nail rod 2, which facilitates the nail rod 2 to be driven into the nail hole, and ensures that when the nail body retreats, the end of the anti-recession teeth 4 can be abutted against the nail hole to prevent retreat. At the bottom of the nail rod 2, ribs 5 are evenly arranged on the surface. These ribs 5 are parallel to the nail rod 2 and are arranged in a circle around it, which will effectively reduce the contact between the nail rod 2 and the inner wall of the nail hole, thereby reducing the friction by reducing the contact area, thereby ensuring that the bottom of the nail rod 2 can quickly and smoothly penetrate into the nail hole, while effectively preventing the nail body from skewing.

[0018] In order to facilitate the nail tip 3 to be hammered into the target body, in this embodiment, as a preferred technical solution of the present utility model, the nail tip 3 is a tapered structure from the nail rod 2, and its cross section gradually decreases.

[0019] In order to improve the overall strength of the nail body, in this embodiment, as a preferred technical solution of the utility model, the nail head 1 is an inverted frustum-shaped structure, and the top of the nail rod 2 is connected to the smaller upper frustum of the nail head 1, and the larger upper frustum of the nail head 1 is evenly provided with anti-slip grooves 6.

[0020] In order to improve the overall strength of the nail body, in this embodiment, as a preferred technical solution of the present utility model, the nail head 1, the nail rod 2, the nail tip 3, the anti-retraction tooth 4 and the rib 5 are an integrated structure, and the whole is made of medium carbon steel.

[0021] In summary, based on the technical solution of the present utility model, when using this product, the tip 3 of the nail should first be accurately contacted and vertically positioned on the target surface, and then the nail body should be smoothly driven into the target body by using a hammering tool. After the tip 3 of the nail smoothly enters the interior of the target body, the rib 5 structure at the bottom of the nail rod 2, which is designed to be parallel to the body of the nail rod 2, will effectively reduce the contact with the inner wall of the nail hole of the target body, thereby reducing the frictional force by reducing the contact surface, so as to ensure that the bottom of the nail rod 2 can quickly and smoothly penetrate into the target body, and at the same time effectively prevent the nail body from skewing. When the part of the nail rod 2 with the rib 5 at the bottom completely enters the target body, continue to drive the part of the nail rod 2 with the anti-backlash teeth 4 designed into the target body. This part of the anti-backlash teeth 4 is designed to extend outwards and the overall diameter is slightly larger than the diameter of the nail rod 2 with the rib 5 at the bottom. The purpose is that during drilling, the anti-backlash teeth 4 in the nail hole will be squeezed by the inner wall of the nail hole, causing the end of the anti-backlash teeth 4 to abut against the inner wall of the nail hole, so that the end of the anti-backlash teeth 4 provides an additional fixing force for the nail body, thereby effectively preventing the nail body from loosening or backing out during use.
