Abstract
The utility model relates to a spiral floor nail with barbs, which comprises a nail cap and a nail rod with a spiral groove. The utility model is characterized in that the side surface of the nail cap is a conical surface and is directly connected with a nail rod surface, the side surface forms an included angle with the nail rod surface, a plurality of spiral barb sections on which the barbs are distributed are arranged on the nail rod, the rotation direction of a spiral channel of the spiral barb section is opposite to the rotation direction of a spiral groove of the nail rod, the barb sections which are oppositely locked and rebounded are distributed on the nail rod, the barb sections are locked more and more tightly under the action of force so no phenomenon of the inverse fleeing of the nail body emerges to enhance the opposite tightening force of a floor and a keel, and simultaneously, no through position is arranged between the nail cap and the nail rod so the nail cap is naturally and smoothly nailed to make convex-concave grooves of the floor conveniently connected in order to bring convenience to construction.
Description
The utility model belongs to a kind of flooring nail, and particularly a kind of hammering into firmly is difficult for the spiral wolf's fang flooring nail that pulls up.
At present the flooring nail that uses of decoration industry adopts the spiral flooring nail more, and this flooring nail is because still there is certain deficiency in the use in structural defective, hammer into the floor as nail after, as long as one looseningly will pull out riveting, thereby the easy perk in floor.Also have a kind of nail surface to be covered with friction projection, approximate wood file when hammering into the floor is also filed when hammering into wooden body and is hindered wooden substance, the nail hole is enlarged, so can not finely play the effect of locking.Therefore under the effect of the power of being everlasting,, the nail body is returned gradually scurry, cause the floor loosening, cause the low-grade worry of enjoying of high gear finishing because the floor produces bounce-back.
The purpose of this utility model is: a kind of spiral wolf's fang flooring nail is provided, distribution many places wolf's fang section on the nail body, wolf's fang likeness in form fish hook, locking firmly after hammering into the floor, use often also and can perk not become flexible, the head of a nail can hammer into wooden body naturally simultaneously, makes the tongue and groove on floor be convenient to connect, and brings convenience to construction.
The purpose of this utility model is achieved in that it comprises the head of a nail, band spiral fluted nail bar, and it is characterized in that: the side of the head of a nail is a conical surface, and directly is connected with the nail pole face, and this face is in a certain angle with the nail pole face; On the nail bar spiral wolf's fang section that multistage is distributed with the wolf's fang tooth is set, the spiral goove sense of rotation of spiral wolf's fang section is opposite with nail bar spiral chute sense of rotation.
The conical surface of the above-mentioned head of a nail is 158-179 degree angle with the nail pole face.
The spiral goove rotation direction of above-mentioned spiral wolf's fang section is the 34-80 degree with nail bar spiral fluted rotation direction angle.
The height of projection of above-mentioned spiral wolf's fang tooth is the 0.25-0.32 millimeter.
The utility model has the advantages that: distribution many places wolf's fang section on the nail body, the wolf's fang profile of tooth is like fish hook, locked relatively bounce-back, under the effect of power, more and more tighter, thereby the phenomenon of body anti-channeling can not appear following closely, and improved the relative fastening force between floor and keel, all improving the insurance degree on the construction process He on the working service.Simultaneously owing to do not have through position between the head of a nail and the nail bar, thereby the head of a nail also can hammer into naturally smoothly, makes the tongue and groove on floor be convenient to connection, brings convenience to construction.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is head of a nail side and nail pole face switching place schematic representation.
