Abstract
The utility model designs a knurling polished rod nail which mainly comprises a nail rod and a nail head. The nail head is flat; a stressed block is arranged in the middle of the nail head and the stressed block is a flat cylinder; the diameter of stressed block corresponds to the diameter of the nail rod; knurls formed through rolling and compressing are arranged on the nail rod; and an upending block is arranged on the nail rod. The middle of the nail head of the knurling polished rod is provided with a stressed block, when the nail is under great impact, the nail head does not deform so that the appearance is more attractive and the situation of scratching people or objects due to the closed angle caused by deformed nail head is avoided. The upending block in use can maintain the large-headed nail and the nail pipe to be on the same axis; the large-headed nail has no declination and cannot lead the large-headed nail to bend or the concrete to crack in the sending process. Knurls formed through rolling and compressing are arranged on the nail rod surface to increase the friction between the nail rod and the wall body, the steel plate and other matrixes, so that the large-headed nail is more firmed and is not easy to loose; the service life of the nail is extended.
Description
Technical field
The utility model relates to the nailing industry, particularly a kind of annular knurl polished rod nail.
Background technique
At present nail on the market generally can only use by artificial or air gun, and this method is difficult to hammer into hard objects because its impact force is not enough for the bigger nail of this class, as concrete wall etc.In a single day promptly enable slowly to hammer into, also need to consume more manpower, and deviation takes place, will cause situations such as nail distortion or concrete burst apart.On the other hand, common nail on the market can not be used with the powerful nailing device of impact force.In nailing device, use owing to be subjected to bigger impact force in addition, ailhead is deformed, influence attractive in appearancely, may form acute angle after the distortion simultaneously, scuffing article or human body.And generally follow closely the smooth nail of bar, and can be after in hammering into matrix because frictional force is not enough, and the expansive force of matrix is little, makes that nail is loosening easily even comes off.
The model utility content
The purpose of this utility model is to provide a kind of can bear greater impact power and the on-deformable annular knurl polished rod nail of ailhead for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the annular knurl polished rod nail that the utility model is designed, it mainly comprises nail bar and ailhead, and ailhead is a tablet, is provided with a force block in the middle of ailhead, force block is a flattened cylindrical shape, the diameter of force block is consistent with the nail shank diameter, and force block is connected by smooth surface with ailhead, and forms distinct level, the nail bar is provided with the decorative pattern that forms by roll extrusion, and the nail bar is provided with righting block.After the setting of this structure made nail be subjected to the enormous impact power of nailing device, any distortion can not take place in ailhead, and outward appearance is more attractive in appearance.
The structure of above-mentioned righting block is: middle is the annulus cover, internal diameter is consistent with the nail shank diameter, evenly be provided with three support plates in the annulus cover outside, support plate is semi-circular, the thickness of support plate is less than the thickness of annulus cover, put with the support plate joint at annulus a plane is set, the distance at support plate solstics and annulus cover center is 6mm.The righting block of this structure, its maximum external diameter is 12mm, nail pipe lucky and nailing device is used.
The resulting annular knurl polished rod nail of the utility model, in the middle of ailhead, be provided with force block, the ailhead of this spline structure, when cooperating nailing device to use, when nail is subjected to huge impact power, ailhead can not deform, thereby appearance is more attractive in appearance, has also avoided simultaneously forming acute angle scuffing human body or article because of the ailhead of distortion.On the other hand, the use of righting block can make nail and nail guarantee and be held on the same axis, and nail deflection can not take place in emission process, causes nail bending or concrete to burst apart.In addition, be provided with the decorative pattern that roll extrusion forms, increased the friction between the matrixes such as nail bar and body of wall, steel plate, make Studs more firm, be difficult for becoming flexible the working life of having improved nail on nail bar surface.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the structural representation of righting block of the present utility model.
1 nail bar, 2 ailheads, 3 righting blocks, 4 support plates, 5 force blocks, 6 decorative patterns, 7 annulus covers.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As Fig. 1, shown in Figure 2, the annular knurl polished rod nail that present embodiment is described, it mainly comprises nail bar 1 and ailhead 2, ailhead 2 is a tablet, in the middle of ailhead 2, be provided with a force block 5, force block 5 is a flattened cylindrical shape, the diameter of force block 5 is consistent with nail bar 1 diameter, force block 5 and ailhead 2 are connected by smooth surface, and form distinct level, and nail bar 1 is provided with the decorative pattern 6 that forms by roll extrusion, nail bar 1 is provided with righting block 3, the structure of righting block 3 is: middle is that annulus overlaps 7, and internal diameter is consistent with nail bar 1 diameter, overlaps 7 outsides at annulus and evenly is provided with three support plates 4, support plate 4 is semi-circular, the thickness of support plate 4 is provided with a plane with support plate 4 joints less than the thickness of annulus cover 7 on annulus cover 7, the distance that support plate 4 solstics and annulus overlap 7 centers is 6mm.The material of this annular knurl polished rod nail is the 45# steel.
