Description

A kind of check bolt
Technical field
It the utility model is related to fastener areas, more particularly to a kind of check bolt.
Background technology
At present, usually used standard bolt is with being combined into, by spring by nut, screw rod, spring washer, plain washer Tension force and screw rod, nut between thread friction power reach locking purpose.In use for some time, or in vibration greatly, frequently Usually there is loose phenomenon in this bolt in the high place of rate.Check bolt on the market often sets on bolt and opened now Mouth pin or series connection wire, but error due to set location often be present, its due intensity is weakened on the contrary.
The utility model patent of Application No. 201420096466.1, a kind of fastening is disclosed apart from adjustable locking spiral shell There is a nuts bolt, screw rod upper end, and screw rod bottom has forward screw thread section to be connected with reverse thread section the thread segment being integrally formed, positive The diameter of thread segment is more than the diameter of reverse thread section, and in forward screw thread section, stop nut center has up and down locking nut The bolt hole of insertion, bolt hole are to be connected together to form by the fastening section and top of bottom the regulation section concentric with fastening section , there is the internal thread corresponding with reverse thread section on fastening section inwall, stop nut is mounted in reverse thread section through internal thread rotation On, its upper surface is in contact with the lower surface of locking nut, forms interlocking structure.The disclosed fastening of above-mentioned patent is apart from adjustable Check bolt, although the locking of locking nut can be realized, the fastening section distance of stop nut is limited, works as locking screw When during mother's locking very close to bolt head, the fastening section of check bolt can not just play a part of fastening.
Utility model content
(1) technical problems to be solved
Problem to be solved in the utility model is to provide a kind of check bolt, and the bolt is not only simple in structure, is novel in design, And anti-loosing effect is good, using stable.
(2) technical scheme
To reach above-mentioned purpose, the utility model provides a kind of check bolt, including screw bolt and nut, the nut thread It is connected on the bolt, is provided with grooving along the length direction of the bolt on the thread segment of the bolt, pacifies in the grooving Equipped with stay, the nut is provided with the rotation stop groove coordinated with the stay, in the spiral shell on the thread segment of the bolt Female outside screw is connected with stop nut.The bolt when in use, the tightening nut first on the thread segment of bolt, connects And stay is placed in the grooving and stay is inserted in the rotation stop groove on the nut, finally in the nut Outside screws the stop nut, in order to prevent that it is described locking that unnecessary stay bending can be fitted in by the loosening of stop nut On one side of nut.
In further technical scheme, the stay is T-shaped, and the width on its head is more than the thread segment of the bolt Diameter, less than the inscribed circle diameter of the nut, the width of its underpart is less than the thread segment diameter of the bolt, the stay Thickness as the width size of the grooving;The setting can effectively ensure that stay is arranged in the grooving, and Tightening for nut is not influenceed.
In further technical scheme, the rotation stop groove is six, and is arranged on evenly and at intervals around the nut axis On the face that the nut contacts with the stop nut, the width of the rotation stop groove is as the thickness size of the stay; The setting can effectively ensure the cooperation of stay and the rotation stop groove.
In further technical scheme, the grooving passes through the axis of the bolt.
In further technical scheme, the nut and the stop nut are hex nut;Using hex nut side Just it is practical.
In further technical scheme, the stay is made up of copper material;Copper material first can be effectively Prevent corrosion, secondly matter is soft, good toughness, bending when be not susceptible to be broken.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has advantages below:The check bolt is simple in construction, makes Stay is placed in the grooving and stay is inserted in the rotation stop groove on the nut by the used time, then in the nut Outside screw the stop nut, can effectively prevent the loosening of nut;In addition to prevent that the loosening of stop nut can So that unnecessary stay bending is fitted on a side of the stop nut, so as to effectively prevent the pine of stop nut It is dynamic.
