Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Crossed countersunk head hand-screw self-locking nail of the present utility model, as depicted in figs. 1 and 2, it comprises ailhead 1, nail body 2 and circular cone cone point 4, the top of described nail body 2 is fixedly connected with integral with ailhead 1, bottom and the circular cone of nail body 2 are bored point 4 and are fixedly connected with integral, described ailhead 1, nail body 2 and circular cone cone point 4 are coaxial setting, both sides in the middle part of described circular cone cone point 4 are symmetrically fixed with a Rhizoma Sparganii latch hook 3 respectively, the side that bottom and the circular cone of each Rhizoma Sparganii latch hook 3 are bored in the middle part of point 4 is fixedly connected with integral (namely Rhizoma Sparganii main cone cutting edge of a knife or a sword down), each Rhizoma Sparganii latch hook 3 and circular cone bore sharp 4 in the middle part of side all there is angle.
In technique scheme, described each Rhizoma Sparganii latch hook 3 and circular cone bore that the angle of side in the middle part of point 4 is equal and angular range is 25 ° ~ 30 °.
In technique scheme, have gap 5 between the side bottom the side on described each Rhizoma Sparganii latch hook 3 top and nail body 2, this gap 5 is beneficial to the utility model and rotates in mother metal.
In technique scheme, be all fixed with reinforcer 6 between the side that the side in the middle part of described each Rhizoma Sparganii latch hook 3 and circular cone bore sharp 4 tops, described reinforcer 6 forms knife edge face with joint, side in the middle part of corresponding Rhizoma Sparganii latch hook 3.Described reinforcer 6 is for ensureing that Rhizoma Sparganii latch hook 3 and circular cone bore sharp 4 intensity be connected.
In technique scheme, the end face of described each Rhizoma Sparganii latch hook 3 is plane.
In technique scheme, described ailhead 1 is smooth rounded head, is convenient to hammer into mother metal.Described nail body 2 is smooth cylinder nail body, and its length can be produced as required.The end face of described ailhead 1 is provided with cross recess 1.1, and cross recess 1.1 is convenient to Torx screwdriver and is carried out manual rotation to nail body.
In technique scheme, the material of crossed countersunk head hand-screw self-locking nail can be any materials that hardness is greater than mother metal.
In technique scheme, the size of the ailhead 1 of crossed countersunk head hand-screw self-locking nail, nail body 2 and sharp 4 each several parts of circular cone cone can carry out independent design, thus makes the utility model be applicable to multiple different occasion.
The utility model can look Environmental Conditions difference, selects clockwise or is rotated counterclockwise.And also can, for different mother metal characteristic, select whether to rotate.
Using method of the present utility model is: first crossed countersunk head hand-screw self-locking nail is hammered into mother metal during use, and after being pinned to the suitable use degree of depth, cross recess 1.1 place using Torx screwdriver to aim at ailhead 1 rotates, and can be determined by circumstances in angle of swing and direction.The main rib cutting edge of a knife or a sword of Rhizoma Sparganii because of Rhizoma Sparganii latch hook 3 down, therefore be convenient to hammer into mother metal, two other rib cutting edge of a knife or a sword is positioned at both sides, can be convenient to rotate after crossed countersunk head hand-screw self-locking nail hammers into mother metal, and after rotating, the function that mother metal inside achieves self-locking is blocked at the top of the Rhizoma Sparganii latch hook 3 of crossed countersunk head hand-screw self-locking nail.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
