Description
Technical field
The utility model is related to a kind of screw, especially a kind of self-tapping screw.
Background technology
In building field, there is the connection between many components to use screw connection, usually used self-tapping screw is main
Including screw head, screw rod and tail point, screw rod and tail point are provided with the screw thread spiraled, and the end of tail point can be the shapes such as fine stern or drilling tail
Formula.The screw head of self-tapping screw is inserted in sleeve, self-tapping screw applied with axial compressive force and radial rotary by power set
Power, rapidly can pierce target object by self-tapping screw.And building is during the use after the completion of construction, by various planted agents
The influence of power, each part can produce skew, can also often bear the effect of the external force such as typhoon, self-tapping screw is in above-mentioned various power
Under effect, particularly as the external force such as violent typhoon than in the case of larger, being uprooped, causing building tie point sometimes
Reduce, reduce safety coefficient.
Utility model content
The purpose of this utility model is to provide a kind of self-tapping screw, the problem of to solve to propose in above-mentioned background technology.
The purpose of this utility model is achieved by following technical proposals：A kind of self-tapping screw, including lead screw, tail
Point, nut, screw tooth and barb, the lower end of the lead screw are provided with tail point, and are structure as a whole with tail point, and peace is fixed in upper end
Equipped with nut；The screw tooth is skewed to be arranged in lead screw；The barb is fixedly mounted on the middle section position of lead screw.
Further, the nut upper end is provided with cross recess.
Further, the angle of inclination of the screw tooth is 20-35 °.
Further, the barb includes mounting seat, hangnail and block.
Further, the hangnail top on the barb is provided with outside oblique angle.
Compared with prior art, the beneficial effects of the utility model are a kind of new self-tapping screw, simple in construction, tension
Remove ability strong, be difficult strongly to be pulled out, using it is simple the advantages of, be adapted to promote the use of.
Brief description of the drawings
Fig. 1 is the utility model overall structure design sketch；
Fig. 2 is the utility model overall structure barb structure for amplifying design sketch；
In figure：1- lead screw, 2- tail points, 3- nuts, 4- screws tooth, 5- barbs.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
As shown in Figure 1-2, the utility model discloses a kind of self-tapping screw, including lead screw 1, tail point 2, nut 3, screw
Tooth 4 and barb 5, the lower end of the lead screw 1 are provided with tail point 2, and are structure as a whole with tail point 2, and upper end is installed with spiral shell
Cap 3；The screw tooth 4 is skewed to be arranged in lead screw 1；The barb 5 is fixedly mounted on the middle section position of lead screw 1, institute
State the upper end of nut 3 and be provided with cross recess, the angle of inclination of the screw tooth 4 is 20-35 °, and the barb 5 includes mounting seat, fallen
Hangnail top on thorn and block, the barb 5 is provided with outside oblique angle.
The self-tapping screw, simple in construction, tension removes ability by force, is difficult strongly to be pulled out, using simple.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
