Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1-2, the super bolt of long stem be conveniently screwed into comprises screw rod, screw head 3, and described screw rod is coaxial with screw head 3, and described screw rod comprises polished rod 4 and screw rod 1, and described screw rod 1 is positioned at polished rod lower end, and described polished rod 4 upper end is connected with screw head 3; Institute's polished rod 4 and screw head 3 joint are provided with cylindrical boss 2, described boss 2 is provided with radial direction through hole 21, described screw head 3 sidewall is provided with several through holes, described screw head 3 sidewall is also provided with anti-slip veins.
Owing to being provided with boss 2 in polished rod upper end, boss 2 being provided with through hole 21, when bolt is screwed into, larger moment can being applied by inserting thin iron staff in through hole 2 to it, thus make to tighten simple to operate, easily realize.
Because super bolt of long stem needs comparatively high pulling torque when tightening, in order to larger moment of torsion can be provided to bolt.Further, described screw head 3 upper surface central position is to being arranged with hexagonal groove 31.By arranging hexagonal groove 31, by interior six sides, it being tightened when tightening, enough moment can be applied.
In order to save production material, reduce manufacture cost, a kind of optimal way of the super bolt of long stem be conveniently screwed into is, the total length a that described screw rod has is 350mm, the second length b that described screw rod 1 has is 50mm, the 3rd length c that described boss 2 has is 6mm, and the 4th length d that described screw head 3 has is 8.2mm, and described screw head 3 has the first radius R
1for 12.3mm, the circumcircle of described hexagonal groove 31 has the second radius R
2for 6.2mm, the diameter that described boss 2 has is 8mm, the diameter of phi that described screw rod has
1for 8mm.
