Abstract
A threaded nail designed by the utility model mainly comprises a nail rod and a nail head, wherein the nail head is a long cylinder, screw threads are arranged on the surface of the nail head, the nail head and the nail rod are in transitional connection through a smooth and curved surface, a wiper block is arranged on the nail rod, and a protection cap is arranged on the nail head. In the threaded nail, as the nail head has a structure that the nail head is the long cylinder, the nail head is not deformed when a nail bears great impulsive force in the case of being matched with a nail shooting device for use; as the screw threads are arranged on the nail head, the screw threads on the nail head can be matched with a screw for fixing an object after the nail is in a base body, and the structure can bear greater load, and the fixing is firmer; on the other hand, the threaded nail is kept to be in the same axial line as a nail pipe, and an eyelet nail is not deflected during the shoot process to avoid the eyelet nail from bending or the concrete from cracking through the use of the wiper block; and the screw threads are protected from being damaged in the shooting process through the use of the protection cap.
Description
Technical field
The utility model relates to the nailing industry, especially a kind of drive screw.
Background technique
Nail on the market generally can only use by artificial or air gun at present, and this method is difficult to hammer into hard objects for the bigger nail of this class, as concrete wall, steel plate etc. because its impact force is not enough.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 addition, general nail its ailhead after hammering into matrix is tablet or sphere, can't fix some objects on ailhead.
The model utility content
The purpose of this utility model is to provide a kind of ailhead to be provided with the drive screw that can be used with nailing device of screw thread for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the drive screw that the utility model is designed, it mainly comprises nail bar and ailhead, the ailhead elongated cylindrical is provided with screw thread on the surface of ailhead, and ailhead is connected by the smooth surface transition with the nail bar, the nail bar is provided with righting block, and ailhead is provided with protective hat.This structure makes on the ailhead can pass through the screw fixed object.
The structure of 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, and the structure of protective hat is a cylinder ring.Such structure can make nail overlap with the central shaft of the nail pipe of nailing device, and can also protect screw thread when emission.
The resulting drive screw of the utility model, its ailhead are oval column type, the ailhead of this spline structure, and when cooperating nailing device to use, when nail was subjected to huge impact power, ailhead can not deform.And ailhead is provided with screw thread, can realize nail behind matrix inside, and the screw thread on the ailhead can cooperate with screw fixes some objects, and such structure can bear bigger load, and fixing more firm.On the other hand, the use of righting block can make drive screw and nail guarantee and be held on the same axis, and the eyelet nail deflection can not take place in emission process, causes eyelet nail bending or concrete to burst apart.The use of protective hat can protect screw thread not to be damaged when emission.
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 protective hats, 5 annulus covers, 6 support plates.
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 drive screw that present embodiment is described, it mainly comprises nail bar 1 and ailhead 2, ailhead 2 elongated cylindrical, surface at ailhead 2 is provided with screw thread, ailhead 2 is connected by the smooth surface transition with nail bar 1, nail bar 1 is provided with righting block 3, ailhead 1 is provided with protective hat 4, the structure of righting block 3 is: middle is that annulus overlaps 5, and internal diameter is consistent with nail bar 1 diameter, overlaps 5 outsides at annulus and evenly is provided with three support plates 6, support plate 6 is semi-circular, the thickness of support plate 6 is provided with a plane with support plate 6 joints less than the thickness of annulus cover 5 on annulus cover 5, the distance that support plate 6 solstics and annulus overlap 5 centers is 6mm, the structure of protective hat 4 is a cylinder ring, and the material of this drive screw is the 45# steel.
Claims (2)
1. drive screw, it mainly comprises nail bar and ailhead, it is characterized in that described ailhead elongated cylindrical, is provided with screw thread on the surface of ailhead, and ailhead is connected by the smooth surface transition with the nail bar, follows closely bar and is provided with righting block, and ailhead is provided with protective hat.
2. drive screw according to claim 1, the structure that it is characterized in that described 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, and the thickness of support plate is less than the thickness of annulus cover, puts with the support plate joint at annulus a plane is set, the distance at support plate solstics and annulus cover center is 6mm, and the structure of protective hat is a cylinder ring.
