Description

Technical Field

[0001] This utility model relates to the field of nail technology, and in particular to a high-strength anti-loosening nail. Background Technology

[0002] Nails are a common metal product, typically used to fasten materials such as wood, boards, and steel bars. They are primarily made of iron or other metals, with a sharp, tapered head and a long, straight body. Nails are widely used in construction, furniture, transportation, and machinery, offering advantages such as stability, reliability, and ease of installation.

[0003] Most nails on the market today rely on vertical penetration to secure themselves to objects. However, vertical nails often lack sufficient friction after penetration, and the nail may deviate during driving, affecting its insertion position or causing it to bend. This compromises the tightness of the connection between the nail and the object, making it easy for the nail to fall off and significantly reducing its effectiveness. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength anti-loosening iron nail, which has the advantages of good anti-loosening effect, good positioning effect and high structural strength.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high-strength anti-loosening nail includes a nail head, a nail shaft, a nail tip, and a positioning seat. The nail shaft is fixed to the lower end of the nail head, and the nail tip is located at the bottom of the nail shaft. The outer side of the nail shaft has several arched grooves, the edges of which are all arc-shaped. A reinforcing strip is fixed to the inner side of each arched groove. The upper edge of the nail tip has an anti-loosening barb. The lower end of the nail head has several insertion blocks, one side of which is fixedly connected to the nail shaft. The upper end of the positioning seat has a positioning groove that cooperates with the anti-loosening barb. The lower end of the positioning seat also has a pre-splitting groove.

[0007] Preferably, the outer side of the nail rod is provided with an anti-slip groove, and the anti-slip groove is spiral-shaped.

[0008] Preferably, a connecting strip is fixed to the lower side of the positioning seat.

[0009] Preferably, the upper end of the nail head is provided with a cross groove.

[0010] Preferably, the surfaces of the nail head, nail shank, and nail tip are all provided with an anti-oxidation coating.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, the worker can place the nail head into the positioning seat and align the bottom of the positioning seat with the surface of the object. When the nail head is inside the positioning groove, the anti-loosening barb on its upper edge is positioned in the positioning groove, thus limiting the nail head. Then, force can be applied to the nail head to move it downwards, allowing the nail head to penetrate into the object. Since the positioning seat is made of plastic, when the nail head moves downwards under force, the positioning seat can crack along the positioning groove. The bottom of the positioning seat is also equipped with a pre-cracked groove, which allows the positioning seat to crack quickly when the nail head is driven into the object, preventing the nail head from contacting the positioning seat. This allows the nail shaft to be completely driven into the object, preventing the nail from deflecting when driven into the object, making the nail drive in more straight, and making the contact between the nail and the object tighter. This further prevents the nail from slipping and loosening, ensuring the anti-loosening effect of the nail. At the same time, the anti-loosening barb further enhances the anti-loosening effect of the nail.

[0013] 2. Several arched grooves can effectively strengthen the structural strength of the nail rod, thereby increasing the overall strength of the nail. At the same time, several reinforcing strips can further strengthen the nail rod, effectively preventing the nail from bending when it is driven into an object, thus ensuring the quality of the nail's use.

[0020] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0021] like Figures 1 to 5 As shown, a high-strength anti-loosening nail includes a nail head 1, a nail shaft 2, a nail head 3, and a positioning seat 4. The nail shaft 2 is fixed to the lower end of the nail head 1, and the nail head 3 is located at the bottom of the nail shaft 2. In use, the worker can place the nail head 3 onto the positioning seat 4, with the bottom of the positioning seat 4 contacting the surface of the object. The upper edge of the nail head 3 has an anti-loosening barb 7. The upper end of the positioning seat 4 has a positioning groove 9, which cooperates with the anti-loosening barb 7. The lower end of the positioning seat 4 also has a pre-splitting groove 10. When the nail head 3 is located inside the positioning groove 9, the anti-loosening barb 7 on its upper edge is located within the positioning groove 9, thus limiting the position of the nail head 3. Force can then be applied to the nail head 1 to move the nail head 3 downwards, allowing it to penetrate the object. Because the positioning seat 4 is made of plastic, when the nail head 3 is subjected to force and moves downwards, the positioning seat 4... The positioning seat 4 is cracked along the positioning groove 9, and a pre-cracked groove 10 is provided at the bottom of the positioning seat 4. Therefore, when the nail head 3 is driven into the object, the positioning seat 4 can quickly crack to prevent the nail head 1 from colliding with the positioning seat 4. This allows the nail shaft 2 to be completely driven into the object, preventing the nail from deflecting when driven into the object, making the nail drive in more straight, and making the contact between the nail and the object tighter. This further prevents the nail from slipping and loosening, ensuring the nail's anti-loosening effect. At the same time, the anti-loosening effect of the nail is further enhanced by the anti-loosening barb 7. A connecting strip 12 is fixed on the lower side of the positioning seat 4. The operator can move the connecting strip 12 to place the positioning seat 4, so that there is a distance between the hand and the nail, further preventing the operator from being accidentally injured when the nail is driven in, and ensuring the operator's safety.

[0022] The nail rod 2 has several arched grooves 5 on its outer side, and the edges of the several arched grooves 5 are all arc-shaped. Each arched groove 5 has a reinforcing strip 6 fixed on its inner side. The several arched grooves 5 can effectively strengthen the structural strength of the nail rod 2, thereby increasing the overall strength of the nail. At the same time, the several reinforcing strips 6 can further strengthen the strength of the nail rod 2, which can effectively prevent the nail from bending when it is driven into an object, thereby ensuring the quality of the nail.

[0023] The lower end of the nail head 1 is fixed with several insertion blocks 8. One side of each insertion block 8 is fixedly connected to the nail rod 2. When the nail rod 2 is driven into the object, the insertion blocks 8 are driven into the surface of the object. The insertion blocks 8 can prevent the nail rod 2 from rotating, so as to ensure a tighter connection between the nail and the object, thereby ensuring the nail's anti-loosening effect.

[0024] The nail rod 2 is also provided with an anti-slip groove 11 on the outside, and the anti-slip groove 11 is spiral in shape. The spiral anti-slip groove 11 can increase the friction between the nail rod 2 and the inside of the object, thereby preventing the nail rod 2 from sliding and further increasing the anti-loosening effect of the nail.

[0025] The top of the nail head 1 is provided with a cross groove 13. The cross groove 13 can be used to verify whether the nail is driven in properly with a Phillips screwdriver. When the nail cannot be turned, it can ensure a tighter connection between the nail and the object.

[0026] The surfaces of the nail head 1, nail shaft 2, and nail head 3 are all coated with an anti-oxidation coating, which prevents oxidation and further improves the service life of the nail.

[0027] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
