Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, specifically to an anti-torsion nail. Background Technology
[0002] A nail is a fastener used to secure objects by driving them into the ground. It is propelled at high speed by a nail gun to fix the object in place, and is widely used in construction, decoration, and carpentry. Currently used nails typically have single cylindrical or conical heads, which results in less than ideal torsional resistance when fixing objects. Utility Model Content
[0003] The purpose of this utility model is to provide an anti-torsion nail, specifically an anti-torsion nail.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] An anti-torsion nail includes a screw and a nail head, wherein the screw and the nail head are integrally formed, and the screw consists of a load-bearing part, a threaded part and a buffer part from top to bottom, and the nail head is placed at the bottom of the buffer part.
[0006] Furthermore, the nail head consists of a connecting part and a fixing part from top to bottom, with a gasket connected to the connecting part.
[0007] Furthermore, the buffer section includes a conical segment and a frustum segment. The conical segment is a cone shape that is narrower at the top and wider at the bottom, and the frustum segment is located at the bottom of the conical segment.
[0008] Furthermore, a nail head is provided at the bottom of the buffer section, and the screw is coaxially arranged with the nail head.
[0009] Furthermore, at least two nail heads are provided at the bottom of the buffer section.
[0010] Furthermore, the two nail heads are symmetrically distributed on both sides of the buffer section.
[0011] Furthermore, the cross-section of the fixing part is circular.
[0012] Furthermore, the cross-section of the fixing part is an equilateral polygon.
[0013] By adopting the above technical solution, the beneficial technical effects of this utility model are:
[0014] This invention improves the nail head. When using a single nail head, its cross-section is polygonal. When the nail is driven into a fixed object, the polygonal edges effectively increase the nail's torsional strength. When using multiple nail heads, the multiple nail heads effectively increase the nail's torsional strength. This invention, through improvements to the nail head, effectively improves the torsional strength of the nail and increases its service life. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of an anti-torsion nail.
[0016] Figure 2 This is a schematic diagram of a torsion-resistant nail with two nail heads.
[0017] Figure 3 This is a schematic diagram of an anti-torsion nail with two polygonal nail heads. Detailed Implementation
[0018] Example 1
[0019] like Figure 1 As shown, an anti-torsion nail includes a screw 1 and a nail head 2, which are integrally formed. The screw 1 consists of a load-bearing part 11, a threaded part 12, and a buffer part 13 from top to bottom. The nail head 2 is located at the bottom of the buffer part 13. When fixing an object, a hole is first drilled in the object. The diameter of the hole is smaller than the circumcircle of the polygonal nail head 2. When the nail is fired into the hole by a nail gun, multiple grooves are added around the hole to fit the edges of the nail head 2, thereby increasing the torsional strength and service life of the nail. During installation, the load-bearing part 11 is located at the firing end of the nail gun, and the nail head 2 is located at the end away from the nail gun. After the nail gun fires the nail, the buffer part 13 provides cushioning to the threaded part 12, preventing damage to the threaded part 12. The cross-section of the load-bearing part 11 is square. When the nail gun fires, the load-bearing part 11 is impacted. The upper end of the load-bearing part 11 expands outward under the impact force, but does not exceed the diameter of the threaded part 12, so that the nut can be installed on the threaded part 12.
[0020] The nail head 2 consists of a connecting part 21 and a fixing part 22 from top to bottom. A washer is connected to the connecting part 21, and the washer also provides a buffering effect for the threaded part 12. The buffering part 13 includes a tapered section 131 and a frustum section 132. The tapered section 131 is a cone shape that is narrower at the top and wider at the bottom, and the frustum section 132 is located at the bottom of the tapered section 131. When the impact force reaches the tapered section 131, the outer side of the tapered section 131 will passively move upward, consuming part of the impact force to ensure the integrity of the threaded part 12.
[0021] A nail head 2 is provided at the bottom of the buffer part 13. The screw 1 is coaxially arranged with the nail head 2, and the cross-section of the fixing part 22 is an equilateral hexagon. The nail head 2 can be set as an equilateral hexagon, and the torsional resistance of the equilateral hexagonal nail head is greater than that of the circular nail head; it can also be set as a conical equilateral polygon, and the torsional resistance of the conical equilateral polygon is slightly less than that of the equilateral hexagon, but still greater than that of the circular nail head.
[0022] Example 2
[0023] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that at least two cylindrical nail heads 2 are provided at the bottom of the buffer part 13, and the channel is also slightly smaller than the diameter of the nail head. The two nail heads 2 are symmetrically distributed on both sides of the buffer part 13, and the cross-section of the fixing part 22 is circular. Since each nail head 2 provides torsional strength, a larger number of nail heads 2 will increase the torsional strength of the nail. In this embodiment, the fixing part 22 can be made into a cone shape that is wider at the top and narrower at the bottom, which effectively increases the speed at which the nail enters the channel and reduces the friction between the nail head 2 and the channel. The cone-shaped nail head still has greater torsional performance than the circular nail head.
[0024] Example 3
[0025] like Figure 3 As shown, the difference between this embodiment and Embodiment 2 is that the cross-section of the fixing part 22 is an equilateral polygon. When the equilateral polygonal nail head 2 enters the channel, a groove adapted to the shape of the nail head 2 will be opened around the channel to increase the torsional strength of the nail. In this embodiment, the fixing part 22 can be made into a cone shape that is wider at the top and narrower at the bottom, which effectively increases the speed at which the nail enters the channel and reduces the friction between the nail head 2 and the channel.
[0026] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
