Boring in tail screw at above-mentioned a kind of lightning, described seal closure is dome shape, the through hole that seal closure upper center has with spiral shell neck diameter mates mutually.
Boring in tail screw at above-mentioned a kind of lightning, have for the sealing groove that sealing-ring embeds in described seal closure, sealing groove is stretched out in sealing-ring embedding sealing groove and lower end local.
Adopt above structure so that screw when boring into hole, the extruding of sealing-ring close bottom crimp, more tight with hole edge, the things such as outside water, dust can be avoided and enter thread segment, destroy the compactness connected and fasten. Seal embedding sealing groove and be fixed on sealing groove by composite gum, avoids its landing, is convenient to the operation of staff, and the interior hole of sealing-ring and seal closure through hole are overlapped in addition.
Boring in tail screw at above-mentioned a kind of lightning, the length of described thread segment is 10��12 times of spiral shell neck length.
Adopt above structure, screw can be improved and bore into firm property during hole.
Boring in tail screw at above-mentioned a kind of lightning, the quantity of described major cutting edge, auxiliary-blade and junk slot is respectively two and be symmetrical arranged with medullary ray.
Boring in tail screw at above-mentioned a kind of lightning, the height of described drill body is 5��10mm, and the height of above-mentioned junk slot is identical with drill body height.
Adopt above structure, it is to increase screw bores the efficiency into hole and chip removal efficiency, can effectively avoid the phenomenon that chip removal causes screw excessively slowly and breaks, namely be convenient to the operation of staff, unnecessary loss can be reduced again.
Compared with prior art, this lightning bore tail screw advantage have following some:
1, this lightning bores spiral shell head in tail screw is also have interior hexagonal groove inside outer-hexagonal shape and its upper end, and staff rotates by spanner or socket screw hexagon wrench and bores tail screw, adds operating method, facilitates operation.
2, this lightning bores in tail screw and is provided with seal closure and sealing-ring, can avoid the things such as outside water, dust and enter screw connection section, it is to increase strength of joint and connection life-span, strengthen the security in operating process.
3, this lightning bores the height raising chip removal efficiency identical with drill body height of junk slot in tail screw, ensure that screw continue to bore into speed, reduce friction and resistance that discharge scrap produces, can effectively avoid the phenomenon that brill tail screw breaks.
Accompanying drawing explanation
Fig. 1 is the front view that this lightning bores tail screw.
Fig. 2 is the vertical view that this lightning bores tail screw.
In figure, 1, spiral shell head; 2, spiral shell neck; 3, thread segment; 4, interior hexagonal groove; 5, seal closure; 6, sealing-ring; 7, drill body; 8, major cutting edge; 9, auxiliary-blade; 10, junk slot; 11, circular platform.
Embodiment
The following is specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.
As shown in Figure 1 and Figure 2, this lightning bores tail screw, comprise spiral shell head 1, bore tail, spiral shell neck 2 and thread segment 3, from on under be respectively spiral shell head 1, spiral shell neck 2, thread segment 3 and bore tail, its spiral shell head 1 is for having interior hexagonal groove 4 inside outer-hexagonal shape and its upper end, spiral shell head 1 time end has the circular platform 11 of reinforcing, circular platform 11 lower surface and seal closure 5 upper end mutually against, spiral shell head 1 can be avoided to contact with the direct of seal closure 5, prevent spiral shell head 1 from wearing and tearing, reduce its work-ing life and strengthen the operation easier to staff.The length of thread segment 3 is 10��12 times of spiral shell neck 2 length in addition, can improve screw and bore into firm property during hole.
Spiral shell neck 2 is provided with seal closure 5, has the sealing-ring 6 mutually mated with it in seal closure 5. Seal closure 5 is dome shape, the through hole that seal closure 5 upper center has with spiral shell neck 2 diameter mates mutually. Having for the sealing groove that sealing-ring 6 embeds in seal closure 5, sealing groove is stretched out in sealing-ring 6 embedding sealing groove and lower end local. Make screw when boring into hole, the close bottom crimp extruding of sealing-ring 6, more tight with hole edge, the things such as outside water, dust can be avoided and enter thread segment 3, destroy the compactness connected and fasten. Seal embedding sealing groove and be fixed on sealing groove by composite gum, avoids its landing, is convenient to the operation of staff, and the interior hole of sealing-ring 6 and seal closure 5 through hole are overlapped in addition.
Bore tail and comprise drill body 7 and major cutting edge 8, the height of drill body 7 is 8mm, major cutting edge 8 is positioned at drill body 7 bottom side and is obliquely installed, major cutting edge 8 is connected with auxiliary-blade 9 on the upside of edge, has the V-shaped junk slot in cross section 10 between major cutting edge 8 and auxiliary-blade 9, and height and the drill body 7 of junk slot 10 are highly identical, improve screw and bore the efficiency into hole and chip removal efficiency, can effectively avoid the phenomenon that chip removal causes screw excessively slowly and breaks, namely be convenient to the operation of staff, unnecessary loss can be reduced again. The quantity of major cutting edge 8, auxiliary-blade 9 and junk slot 10 is respectively two and be symmetrical arranged with medullary ray in addition.
Ultimate principle: when using brill tail screw fixing, the top of screw thread drill body 7 first touch fasteners, then while deep gradually, it is positioned at drill body 7 bottom side and the major cutting edge 8 that is obliquely installed starts effect, then auxiliary-blade 9 starts effect, rotate the discharge produced to be discharged by junk slot 10, owing to junk slot 10 is bigger, chip removal efficiency height, screw can not be affected continue to bore into speed, reduce friction and resistance that discharge scrap produces, avoid boring tail screw to break, when turning tight brill tail screw, sealing-ring 6 can be connected with hole edge compactness by pressure, avoid outside water, the things such as dust enter screw connection section, improve strength of joint and connect the life-span. having interior hexagonal groove 4 inside spiral shell head 1 upper end, be convenient to the operation of staff, staff can be rotated by spanner and socket screw hexagon wrench and bore tail screw, adds operating method.
Specific embodiment described herein is only to the utility model spirit explanation for example. Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by the utility model person of ordinary skill in the field, but can't deviate spirit of the present utility model or surmount the scope that appended claims defines.
Although more employing the terms such as spiral shell head 1, spiral shell neck 2, thread segment 3, interior hexagonal groove 4, seal closure 5, sealing-ring 6, drill body 7, major cutting edge 8, auxiliary-blade 9, junk slot 10, circular platform 11 herein, but do not get rid of the possibility using other term. These terms are used to be only used to describe and explain essence of the present utility model more easily; They are construed to any a kind of additional restriction all disagree with the utility model spirit.
