Abstract

The utility model relates to a bolt, in particular to a double-head locking bolt and belongs to the technical field of standard parts. The double-head locking bolt comprises a first screw rod, a bolt head and a second screw rod, wherein the first screw rod and the second screw rod are respectively arranged on two sides of the bolt head. The double-head locking bolt is characterized in that the direction of a thread of the first screw rod is opposite to that of a thread of the second screw rod. Compared with the prior art, the double-head locking bolt has the advantages of being simple in structure, reasonable in design, reliable in performance and convenient to use. When used, two connection parts are respectively connected with the first screw rod and the second screw rod. After the bolt head is fixed through a wrench, the bolt head is fixed through a tightening connection part. Due to the fact that the thread direction of the first screw rod is opposite to that of the second screw rod, after the double-head locking bolt is tightened, the bolt is not easy to loosen. When a certain connection part needs dismantling, people just need to fix the bolt head and dismantle the connection part.

Description

A kind of double end lock bolt
Technical field
The utility model relates to a kind of bolt, especially relates to a kind of double end lock bolt, belongs to the standard piece technical field.
Background technique
Stud bolt is used for the connection between two links.Stud bolt generally comprises the first threaded stem, the second threaded stem and polished rod, the hand of spiral of the first threaded stem and the second threaded stem is consistent, when needs are pulled down one of them link, because the degree of the tightening difference of two links, usually the link that the degree of tightening is lower will be backed out, and can therefore bring inconvenience.During the equidirectional motion of two other link, common stud bolt might cause an end to become flexible.
The model utility content
The purpose of this utility model is to overcome above shortcomings in the prior art, and provides a kind of reasonable in design, double end lock bolt easy to use.
The technical scheme in the invention for solving the above technical problem is: this double end lock bolt, comprise the first threaded stem, bolt head and the second threaded stem, described the first threaded stem and the second threaded stem are separately positioned on the both sides of bolt head, it is characterized in that the hand of spiral of described the first threaded stem and the second threaded stem is opposite.
Bolt head described in the utility model is hexagon.
The incircle of outer-hexagonal described in the utility model guarantees the intensity of bolt head, the damage of bolt head when preventing from tightening greater than the major diameter of thread of the first threaded stem and the second threaded stem.
The utility model compared with prior art has the following advantages and effect: simple in structure, reasonable in design, and reliable performance, easy to use.During use, two links are connected in respectively on the first threaded stem and the second threaded stem, after bolt head is fixed with spanner, fix by tightening link, because the hand of spiral of the first threaded stem and the second threaded stem is opposite, be not easy to become flexible after therefore tightening.And when needing certain a connection piece of dismounting, only need fix bolt head, pull down this link and both can.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is left view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1~Fig. 2, double end lock bolt in the present embodiment comprises the first threaded stem 1, bolt head 2 and the second threaded stem 3, the first threaded stem 1 and the second threaded stem 3 are separately positioned on the both sides of bolt head 2, and the hand of spiral of the first threaded stem 1 and the second threaded stem 3 is opposite.
Bolt head 2 in the present embodiment is the outer-hexagonal shape, and hexagonal inscribed circle diameter A guarantees the intensity of bolt head, the damage of bolt head when preventing from tightening greater than the major diameter of thread B of the first threaded stem and the second threaded stem.
During use, two links are connected in respectively on the first threaded stem 1 and the second threaded stem 3, after bolt head 2 usefulness spanners are fixed, fix by tightening link, because the hand of spiral of the first threaded stem 1 and the second threaded stem 3 is opposite, be not easy to become flexible after therefore tightening.And when needing certain a connection piece of dismounting, only need fix bolt head 2, pull down this link and get final product.
In addition, need to prove, the specific embodiment described in this specification, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification only is to the explanation of the utility model structure example.Allly conceive equivalence variation or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
