Description
Technical field
Machanical fastener technical field is the utility model is related to, specifically a kind of round end washer cross Self Drilling Screws.
Background technology
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages
The instrument of implements parts；Self Drilling Screws is the new invention of people in recent years, is also self-tapping screw, the afterbody of Self Drilling Screws is in drilling tail
Or fine stern shape, without secondary process, can directly material is set, drilling, tapping, locking on basic material, significantly save and construct
Time, however, Self Drilling Screws learies of the prior art are very big, and easily occurs drilling tail work among the process of processing
The low situation of efficiency, to improve operating efficiency, reduce scrappage and production cost, the utility model proposes a kind of round end washer
Cross Self Drilling Screws.
Utility model content
Technical problem to be solved in the utility model is the shortcomings that overcoming prior art, there is provided a kind of round end washer ten
Word Self Drilling Screws, improves operating efficiency and practicality, reduces scrappage, reduces production cost.
The utility model solve above technical problem technical scheme be：
A kind of round end washer cross Self Drilling Screws, including nut, screw rod and the drilling tail set gradually, nut, screw rod with
And drilling tail is formed in one structure；The junction of nut and screw rod is provided with protective cover, disc and spiral shell of the screw rod perpendicular to protective cover
The axis of bar along its length passes through the center of circle of protective cover；
One side of the protective cover away from nut is equipped with washer pad, and washer pad uniformly divides in the one side away from protective cover
The multiple sharp cone distals of cloth fix drilling tails, and fixed drilling tail offers screw thread parallel to screw rod on screw rod around its whole body；
Drilling tail is sharp cone distal, and it is hollow cutting structure that it is internal, that is, forms internal cavities, be filled with inside internal cavities
Anticorrosion silicon rubber, the groove for chip removal is offered in sharp cone distal drilling tail.
The technical scheme that the utility model further limits is：
Foregoing round end washer cross Self Drilling Screws, protective cover use nylon material, and the washer pad on protective cover uses
Stainless steel.
Foregoing round end washer cross Self Drilling Screws, the middle part of end face of the nut away from protective cover form island shape and protruded
Portion, the upper surface of protuberance offer cross docking recess.
Foregoing round end washer cross Self Drilling Screws, the material of anticorrosion silicon rubber is polysiloxanes high molecular polymer.
Foregoing round end washer cross Self Drilling Screws, nut are rigid quality of rubber materials, and the outer surface of screw rod and drilling tail is equal
With zinc coat.
The beneficial effects of the utility model are：
The junction of technical scheme designed by the utility model, nut and screw rod is provided with protective cover, and protective cover is provided with
Washer pad, and fixed drilling tail is uniformly provided with washer pad, operating efficiency is effectively raised, is made between screw and workpiece more
Add firmly, fixed drilling tail and the drilling tail cooperation of screw bottom are had an effect, and alleviate the workload of staff so that screw is tight
Gu effect is good, time saving and energy saving, the cutting portion of screw is hollow-core construction, and moistureproof silicon rubber is filled with hollow-core construction, is changed
The big present situation of screw learies, silicon rubber can be moistureproof, strengthen the practicality and utilization rate of screw, reduce learies, protect
Environment has been protected, and the technical scheme is simple in construction, it is easy to use, safeguard simple.
