Description

Technical Field

[0001] The utility model belongs to the field of hardware, and in particular relates to an anti-dropping nail. Background Art

[0002] The principle of using nails at present is to use the friction force formed by the cylindrical nail body of the nail and the object being nailed to play a fixing role. If only the friction force is used, the anti-slip effect is ultimately limited. Utility Model Content

[0003] The utility model provides an anti-dropping nail, which effectively solves the problems in the background technology, further increases the fixing force, and effectively prevents the nail from dropping out.

[0004] The utility model provides an anti-dropping nail, wherein a groove is arranged between the root of the nail tip and the pointed head.

[0005] As a further optimization of the present invention, the groove is annular.

[0006] As a further optimization of the present invention, the cross section of the groove is hook-shaped.

[0007] As a further optimization of the utility model, a notch is provided at the hook end of the groove.

[0008] As a further optimization of the present invention, eight notches are provided and arranged in a circular array.

[0009] As a further optimization of the utility model, the notch forms a barb on the pointed tip.

[0010] As a further optimization of the utility model, the hook tip portion of the groove is arc-shaped, and the hook handle portion of the groove is straight-line.

[0011] After the anti-dropping nail provided by the utility model is driven into the nailed object, the compressed tissue of the nailed object enters the groove under the action of deformation recovery force, thereby preventing the nail from falling off. The groove is arranged between the root of the nail tip and the pointed head, that is, arranged on the inclined surface of the nail tip. The arrangement of this position does not increase the resistance of the nail being driven into the nailed object, but also reduces the contact area between the nail and the nailed object, thereby reducing the resistance of the nail entering. The groove forms a barb structure on the pointed head, and the barb can increase the resistance, thereby preventing the nail from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of this embodiment;

[0013] Figure 2 yes Figure 1 Schematic cross-section;

[0014] Figure 3 yes Figure 1 A partial enlarged schematic diagram;

[0015] Among them, there are a nail head 1, a nail body 2, a nail tip 3, a pointed head 3a, a notch 3a1, and a groove 3b. DETAILED DESCRIPTION

[0016] A nail generally comprises a nail head 1, a nail body 2 and a nail tip 3. Figure 1-3 As shown, in this embodiment, a groove 3 b is provided between the root of the nail tip 3 and the pointed head 3 a to form an anti-dropping nail, wherein the root is the transition point between the nail tip 3 and the nail body 2 .

[0017] After the anti-dropout nail is nailed into the nailed object, the nailed object is squeezed into the groove 3b under the action of the deformation recovery force by the squeezed tissue, which plays a role in preventing it from falling off. The groove 3b is just set on the inclined surface of the nail tip 3. When the nail tip 3 enters the nailed object, no matter whether there is tissue in the nailed object entering the groove 3b, it will not form resistance to the anti-dropout nail entering the nailed object. In fact, the setting of the groove 3b also reduces the contact area between the anti-dropout nail and the nailed object, reducing the resistance to entry. When removing the nail, the groove 3b causes the tip 3a to form a barb structure, which increases the resistance when removing the nail and effectively prevents it from falling off.

[0018] In addition, the barb of the pointed tip 3a can undergo a certain degree of contraction deformation when squeezed by the nailed object, and the restoring force of the contraction deformation will further increase the squeezing force with the nailed object tissue, further enhancing the anti-dropout effect of the anti-dropout nail.

[0019] Further, the groove 3b in this embodiment is configured as a ring structure with a hook-shaped cross section. In other embodiments, the groove 3b may also be configured as a ring structure with a trapezoidal or semicircular cross section, or a hook-shaped arc structure, etc., according to specific requirements.

[0020] Preferably, in this embodiment, a notch 3a1 is provided at the hook end of the groove 3b. Specifically, eight notches 3a1 are provided and arranged in a circular array. The provision of the notch 3a1 can provide space for the deformation of the barb and is more conducive to the deformation of the barb. In other embodiments, the notches 3a1 may also be four or three, or may be arranged in a non-array manner, depending on the specific situation.

[0021] Furthermore, in the present embodiment, the groove 3b is a structure with a hook-shaped cross-section, specifically including a hook tip and a hook handle. The hook tip adopts an arc-shaped structure, and the hook handle adopts a straight-line structure. This structure is easier to process, and the arc shape of the hook tip can increase the volume of the tissue of the object being nailed when the nail is removed, thereby increasing the anti-slip force.

[0022] In other embodiments, the notch 3a1 may be larger so that the pointed tip 3a directly forms a barb structure.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
