Abstract
The utility model relates to a knurled stud, which mainly comprises a stud head and a stud rod, wherein the stud head is flat; the stud head and the stud rod are connected through a smooth surface; a decorative pattern is formed on stud rod through rolling; and a plastic wiper block is arranged on the stud rod. By adopting the flat stud head with the external diameter of 10mm, the stressed area of the piston of a stud gun on the stud head is enlarged and the impact force on the stud in the stud gun is increased. The increase of the diameter of the stud head improves the fixing capability of the stud for the object. On the other hand, the plastic wiper block enables the stud and a stud tube to be coaxial, so as to prevent the stud from being bent or concrete from being cracked due to the deviation of the stud during the stud shooting process. Furthermore, the decorative pattern formed on the surface of the stud rod through rolling increases the friction between the stud rod and base bodies like a wall body, a steel plate and so on, thereby enabling the stud fixation to be firmer and harder to loose, and prolonging the service life of the stud.
Description
Technical field
The utility model relates to the nailing industry, particularly a kind of annular knurl Studs.
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.The less nail of other ailhead causes the nail distortion easily when ailhead is firmly big.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 annular knurl Studs that can bear greater impact power and be difficult for loose or dislocation for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the annular knurl Studs that the utility model is designed, it mainly comprises ailhead and nail bar, ailhead is a tablet, ailhead is connected by smooth surface with nail bar joint, and the nail bar is provided with the decorative pattern that forms by roll extrusion, and the nail bar is provided with the plastics righting block.Such structure has increased frictional force between nail bar and the matrixes such as body of wall or steel plate, makes nail be difficult for loose or dislocation.
The diameter of above-mentioned ailhead is 10mm, and the structure of plastics righting block is: middle is the annulus cover, evenly is provided with eight rectangular strips that size is identical in the annulus cover outside, and the internal diameter of annulus cover is consistent with the external diameter of nail bar, and the external diameter of plastics righting block is 12mm.This structure makes the central shaft of nail bar overlap with the central shaft of nail pipe, makes nail deflection can not take place when emission.
The resulting annular knurl Studs of the utility model, its ailhead is a tablet, external diameter is 10mm, the ailhead of this spline structure, when cooperating nailing device to use, increased the lifting surface area of piston on ailhead of nailing device, increased Studs suffered impact force in nailing device, made it can hammer into hard object more easily.The increase of ailhead diameter can increase the crystallized ability to object simultaneously.On the other hand, the use of plastics righting block can make Studs and nail guarantee and be held on the same axis, and Studs deflection can not take place in emission process, causes Studs 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 plastics righting block of the present utility model.
1 nail bar, 2 ailheads, 3 plastics righting blocks, 4 annulus covers, 5 rectangular strips, 6 decorative patterns.
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 Studs that present embodiment is described, it mainly comprises ailhead 2 and nail bar 1, ailhead 2 is a tablet, the diameter of ailhead 2 is 10mm, ailhead 2 is connected by smooth surface with nail bar 1 joint, nail bar 1 is provided with the decorative pattern 6 that forms by roll extrusion, nail bar 1 is provided with plastics righting block 3, the structure of plastics righting block 3 is: the centre is overlapped 4 outsides at annulus and evenly is provided with eight rectangular strips 5 that size is identical for annulus cover 4, and the internal diameter of annulus cover 4 is consistent with the external diameter of nail bar 1, the external diameter of plastics righting block 3 is 12mm, and the material of this annular knurl Studs is the 45# steel.
Claims (2)
1. annular knurl Studs, it mainly comprises ailhead and nail bar, it is characterized in that described ailhead is a tablet, and ailhead is connected by smooth surface with nail bar joint, and the nail bar is provided with the decorative pattern that forms by roll extrusion, follows closely bar and is provided with the plastics righting block.
2. the Studs of band pad according to claim 1, the diameter that it is characterized in that described ailhead is 10mm, the structure of plastics righting block is: middle is the annulus cover, evenly be provided with eight rectangular strips that size is identical in the annulus cover outside, the internal diameter of annulus cover is consistent with the external diameter of nail bar, and the external diameter of plastics righting block is 12mm.
