Description
Technical field
The utility model relates to a kind of bolt, is specifically related to a kind of high-strength bolt with replacement head.
Background technique
Bolt is one of the most common fastening piece in machinery industry.Existing bolt, it generally comprises as holistic bolt head and screw rod, and the end face be connected with screw rod bottom bolt head is plane.Bolt head can be provided with hexangle type or cross groove, proper implements can be used to embed in these grooves bolt is carried out tightening or unscrewing, in routine use process, the bolt that frequent appearance causes because bolt head is used for fastening groove wearing and tearing cannot normally use, great potential safety hazard can be brought time serious, bolt of the present utility model, not only itself has fastening function, according to the demand of different use occasion, for bolt provides multiple replacement head, reliably be connected between replacement head with bolt head, bolt can be made to meet the needs of different occasion, also the replacement head of different size immediately can be replaced when wearing and tearing appear in bolt head time, greatly facilitate the use of bolt.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of high-strength bolt with replacement head, the use difficulty that bolt of the present utility model effectively can prevent bolt head from wearing and tearing and cause, and carries replacement head, and multiple screws cutter can be coordinated to use.
Following scheme is adopted in order to reach above-mentioned technical purpose the utility model:
A kind of high-strength bolt with replacement head, comprise bolt shank, bolt head and replacement head, the upper end of described bolt shank is provided with bolt head, the lower end of bolt shank is provided with threaded one end section, described bolt head is the sleeve of an outer-hexagonal shape, the inwall of bolt head is evenly equipped with the fin of 6 rectangles, the position of described fin is corresponding with six vertical side edge of outer-hexagonal shape sleeve respectively, described replacement head is provided with the groove corresponding with rectangular fin on sleeve lining, replacement head is in fin and groove stud bolt head, and replacement head is provided with special fastening grooves.
By technique scheme, specialization of the present utility model is, bolt head is the sleeve of an outer-hexagonal shape, one: the bolt head of this shape can be convenient to use socket wrench and carry out degree of tightness; Its two: when outer-hexagonal shape bolt head use wearing and tearing, or operator is when lacking socket wrench on hand, replacement head, in groove and fin embedding outer-hexagonal shape sleeve, because replacement head is provided with special fastening grooves, therefore can use the screw-driver of the model that matches to carry out degree of tightness to bolt.
Further, the inwall of bolt head described in the utility model is interior hexagon, top edge 0.2 ~ the 0.5cm of the upper end distance sleeve lining of the rectangular fin on sleeve lining, in the technical program, the inwall of sleeve is designed to interior hexagon, fin and sleeve top edge leave certain distance, in fact bolt are become again a hexagon socket head cap screw, can be convenient to use inner hexagon spanner degree of tightness.
Further, the thread section of bolt shank lower end described in the utility model is provided with and runs through screw rod and axially extended positioning hole.
Further, replacement head described in the utility model is provided with at least one, and each replacement head is provided with different special fastening grooves, by the technical program, is the replacement head that a set of specification of this type of bolt preparation is different, facilitates the user demand under multiple occasion.
Further, special fastening groove described in the utility model can be any one in yi word pattern, cross, quincunx, triangle, square, hexagon.
The beneficial effects of the utility model are: 1. bolt head of the present utility model uses the sleeve of outer-hexagonal shape, and the bolt head of this shape not only can be convenient to use socket wrench and carry out degree of tightness; And when outer-hexagonal shape bolt head uses wearing and tearing, or operator is when lacking socket wrench on hand, replacement head, in groove and fin embedding outer-hexagonal shape sleeve, because replacement head is provided with special fastening grooves, therefore can use the screw-driver of the model that matches to carry out degree of tightness to bolt.2. high-strength bolt of the present utility model is equipped with the different replacement head of the specification of a set of different size, facilitates the user demand under multiple occasion.
