Abstract
A cone-shaped disk head inner hexagonal bolt comprises a cone-shaped end head, an inner hexagonal blind hole, a threaded rod and the like. The inner hexagonal blind hole is arranged in the top of the cone-shaped end head, six cross sections of the inner hexagonal blind hole are arc-shaped, the bottom of the inner hexagonal blind hole is cone-shaped, the outer surface of the cone-shaped end head is a cone-shaped disk surface, the inner surface of the cone-shaped end head is a planar disk surface, the diameter of the cone-shaped end head is larger than that of the threaded rod, the diameter of the inner hexagonal blind hole is smaller than that of the threaded rod, circular spiral threaded teeth are arranged on the threaded rod, and the threaded teeth are arranged at the same angle. The cone-shaped disk head inner hexagonal bolt has the advantages of being capable of bearing larger tightening torque, good in connection strength, large in fastening force, beneficial to connection of parts and compact in structure.
Description
Technical field:
The utility model relates to a kind of screw, is specifically related to a kind of taper coiled hair hexagon socket head cap screw.
Background technique:
It is very widely that hexagon socket head cap screw uses at machinery industry, and hexagon socket head cap screw is when screwing or dismantle, on six planes of the Point of Strength of spanner hexagonal blind hole in the termination.But in long-term using process a fatal shortcoming being arranged is exactly hexagonal cunning side to occur easily, because in the plane of the general recessed equipment component of hexagon socket head cap screw, but be not exposed to the clamping point of outside, cause and take out relatively difficulty of damaged bolt, people often take a lot of ways, but slightly do not note or removing method improper, cause damage will for machinery itself, also may cause thoroughly scrapping of equipment component when serious, cause larger economic loss, but also waste time and energy.
The model utility content:
For the technical deficiency of existing the said goods, the purpose of this utility model is to provide a kind of taper coiled hair hexagon socket head cap screw, and it is comprised of cone-shaped end, interior hexagonal blind hole, screw rod etc.
The technological scheme that its technical problem that solves the utility model adopts is: be provided with interior hexagonal blind hole in the cone-shaped end top, six cross sections of interior hexagonal blind hole are arc, the bottom of interior hexagonal blind hole is conical bottom, the appearance of cone-shaped end is the tapered disk face, table is the flat circle card in the cone-shaped end, and the diameter of interior hexagon end head is greater than screw diameter, and interior hexagonal blind hole diameter is less than screw diameter, screw rod is provided with the thread with round spiral, and thread is the arrangement with angle.
The beneficial effects of the utility model are: bear larger screw-down torque, join strength is high, and fastening strength is larger, is connected compact structure between the feature.
Description of drawings:
Fig. 1 is the utility model overall structure schematic representation;
Fig. 2 is the utility model cone-shaped end structural representation;
Among the figure, 1, cone-shaped end 2, interior hexagonal blind hole 3, screw rod 4, tapered disk face 5, flat circle card 6, cross section 7, round edge edge
Embodiment:
As shown in the figure, a kind of taper coiled hair hexagon socket head cap screw, it is comprised of cone-shaped end 1, interior hexagonal blind hole 2, screw rod 3, cylindrical card 4, cylindrical card 5, cross section 6.Be provided with interior hexagonal blind hole 2 in cone-shaped end 1 top of bolt, six cross sections 6 of interior hexagonal blind hole 2 are arc, the bottom of interior hexagonal blind hole 2 is conical bottom, the appearance of cone-shaped end 1 is tapered disk face 4, table is flat circle card 5 in the cone-shaped end 1, tapered disk face 4 is provided with round edge along 7 with flat shape disc face 5 contacting points, makes bolt in the plane of recessed equipment component, takes out the bolt ratio and is easier to; The diameter of cone-shaped end 1 is greater than screw rod 3 diameters, and interior hexagonal blind hole 2 diameters are less than screw rod 3 diameters, and screw rod 2 is provided with the thread with round spiral, and each circular thread is the arrangement with angle, compact overall structure.
