Abstract
The utility model relates to New self-tapping screw, and it comprises nut and the screw rod of order setting; Described nut is cylindrical, and the diameter in cross section is c, has 6.0mm≤c≤6.3mm; Described screw rod is the cylindricality with V thread screw, and the diameter in cross section is f, has 2.80mm≤f≤3.00mm; Described screw rod is set with packing ring, and the diameter of this packing ring is b, has 15.40mm≤b≤16.00mm.The New self-tapping screw that the utility model provides, by nut, packing ring and the cooperation of cylindricality screw rod with V thread screw, make New self-tapping screw simultaneously can complete tapping, one side completes and locking operation, quite convenient; At utmost challenge, utilize the deformability of material by intense beam mould, once complete expansion, diameter reducing process.
Description
Technical field
The utility model relates to hardware field, especially a kind of New self-tapping screw that can complete tapping simultaneously and lock function.
Background technique
Along with the paces of modernization construction constantly advance, the process requirements for screw is more and more higher, and for special technological requirement, existing plain screw can not complete tapping simultaneously and lock function, has certain narrow limitation, can not meet technological requirement.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of New self-tapping screw that can complete tapping simultaneously and lock function.
The utility model solves technological scheme that its technical problem adopts: New self-tapping screw, comprises nut and the screw rod of order setting; Described nut is cylindrical, and the diameter in cross section is c, has 6.0mm≤c≤6.3mm; Described screw rod is the cylindricality with V thread screw, and the diameter in cross section is f, has 2.80mm≤f≤3.00mm; Described screw rod is set with packing ring, and the diameter of this packing ring is b, has 15.40mm≤b≤16.00mm, and the thickness of described packing ring is d, has 0.70mm≤d≤1.05mm.
As preferably, the length of described screw rod is e, has 11mm≤e≤13mm.
As preferably, described nut is provided with plum blossom cave, the thickness of described nut is a, has 1.6mm≤a≤2.0mm.
The beneficial effects of the utility model are: New self-tapping screw of the present utility model, and by nut, packing ring and the cooperation of cylindricality screw rod with V thread screw, make New self-tapping screw simultaneously can complete tapping, one side completes and locking operation, quite convenient; Because screw diameter f is less, be that 2.80mm≤f≤3.00mm, head diameter c are comparatively large, be 6.0mm≤c≤6.3mm, at utmost challenge, utilize the deformability of material by intense beam mould, once complete expansion, diameter reducing process.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings;
Fig. 1 is schematic front view of the present utility model;
Fig. 2 is schematic top plan view of the present utility model;
In figure, 1-nut, 2-screw, 3-packing ring, 4-plum blossom cave.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described, but protection domain of the present utility model is not limited to the following stated.
As Figure 1-Figure 2, New self-tapping screw of the present utility model, comprises nut 1 and the screw rod 2 of order setting; Described nut 1 is cylindrical, and the diameter in cross section is c, has 6.0mm≤c≤6.3mm; Described screw rod 2 is for having the cylindricality of V thread screw, and the diameter in cross section is f, has 2.80mm≤f≤3.00mm; Described screw rod 2 is set with packing ring 3, and the diameter of this packing ring 3 is b, has 15.40mm≤b≤16.00mm.New self-tapping screw of the present utility model, by nut 1, packing ring 3 and the cooperation of cylindricality screw rod 2 with V thread screw, make New self-tapping screw simultaneously can complete tapping, one side completes and locking operation, quite convenient; Because screw rod 2 diameter f is less, be 2.80mm≤f≤3.00mm, nut 1 diameter c is comparatively large, is 6.0mm≤c≤6.3mm, is at utmost challenged, utilized the deformability of material during use by intense beam mould, once complete expansion, diameter reducing process.It should be noted that the effect mainly locking and increase lifting surface area of packing ring 3, prevent mechanical deterioration, the thickness of described packing ring 3 is d, has 0.70mm≤d≤1.05mm.
The length that it should be noted that described screw rod 2 is e, has 11mm≤e≤13mm.
It should be noted that and described nut 1 is provided with plum blossom cave 4, the thickness of described nut 1 is a, has 1.6mm≤a≤2.0mm.It should be noted that described plum blossom cave 4 also can use cross cave, but conveniently quick assembling, as excellent be adopt plum blossom cave 4.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
