Abstract
The utility model discloses an external hexagonal bolt, comprising a stud and an external hexagonal bolt head, wherein one layer of circular baffle plate is arranged between the stud and the external hexagonal bolt head; the baffle plate is larger than the inscribed circle of the external hexagonal bolt head in diameter; a second baffle plate having the same appearance with the circular baffle plate is arranged on the other side, opposite to the circular baffle plate, of the external hexagonal bolt head. By the adoption of the external hexagonal bolt provided by the utility model, the separation of a spanner away from the external hexagonal bolt head in the course of screwing or unscrewing is prevented, so that the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of bolt, and more particularly, it relates to a kind of outer-hexagonal bolt.
Background technique
Outer-hexagonal bolt in existing industry is tightened with stiff hand or adjustable spanner conventionally; in rundown process, spanner often can be because the angle problem that overexerts or have an effect detaches outer-hexagonal; make inconvenience in outer-hexagonal bolt tightening process, so that make to tighten inefficiency.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of outer-hexagonal bolt of departing from from hexagon spiral shell head of preventing in rundown process.
For achieving the above object, the utility model provides following technological scheme: a kind of outer-hexagonal bolt, comprise double-screw bolt and outer-hexagonal spiral shell head, between described double-screw bolt and outer-hexagonal spiral shell head, be provided with one deck rounded stops, described block diameter is greater than the inscribed circle diameter of outer-hexagonal spiral shell head, and described outer-hexagonal spiral shell head is provided with second block identical with rounded stops external form on the opposite side with respect to rounded stops.
By adopting technique scheme, at outer-hexagonal spiral shell head, be respectively arranged with up and down the second block and rounded stops, spanner can be stretched between the second block and rounded stops, after coordinating with outer-hexagonal spiral shell head, tighten, in this case, spanner has block to block the scope that just can not detach outer-hexagonal spiral shell head up and down, has facilitated tightening of outer-hexagonal bolt, has improved and has tightened efficiency.
The utility model is further set to: described the second block and outer-hexagonal spiral shell head are one-body molded setting.
By adopting technique scheme, guaranteed the join strength between the second block and outer-hexagonal spiral shell head, guaranteed in using process not fragilely, guaranteed working life.
The utility model is further set to: on described the second block, be provided with straight groove.
By adopting technique scheme, increased tightening or unscrewing mode of outer-hexagonal bolt, can select suitable mode according to different operating modes, improved the practicability of outer-hexagonal bolt.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model outer-hexagonal bolt example.
Drawing reference numeral explanation:
1, the second block; 2, rounded stops; 3, outer-hexagonal spiral shell head; 4, double-screw bolt; 5, straight groove.
Embodiment
With reference to Fig. 1, the utility model outer-hexagonal bolt embodiment is described further.
A kind of outer-hexagonal bolt, comprise double-screw bolt 4 and outer-hexagonal spiral shell head 3, between described double-screw bolt 4 and outer-hexagonal spiral shell head 3, be provided with one deck rounded stops 2, described block diameter is greater than the inscribed circle diameter of outer-hexagonal spiral shell head 3, and described outer-hexagonal spiral shell head 3 is provided with second block 1 identical with rounded stops 2 external forms on the opposite side with respect to rounded stops 2.
By adopting technique scheme, at outer-hexagonal spiral shell head 3, be respectively arranged with up and down the second block 1 and rounded stops 2, spanner can be stretched between the second block 1 and rounded stops 2, after coordinating with outer-hexagonal spiral shell head 3, tighten, in this case, spanner has block to block the scope that just can not detach outer-hexagonal spiral shell head 3 up and down, has facilitated tightening of outer-hexagonal bolt, has improved and has tightened efficiency.
Described the second block 1 is one-body molded setting with outer-hexagonal spiral shell head 3.
By adopting technique scheme, guaranteed the join strength between the second block 1 and outer-hexagonal spiral shell head 3, guaranteed in using process not fragilely, guaranteed working life.
On described the second block 1, be provided with straight groove 5.
By adopting technique scheme, increased tightening or unscrewing mode of outer-hexagonal bolt, can select suitable mode according to different operating modes, improved the practicability of outer-hexagonal bolt.
Claims (3)
