Abstract
The utility model discloses a double screw thread lockbolt, comprising bolt caps, a screw, screw threads and nuts. The bolt caps adopt the hexagonal standard component form, and the screw is crossedly provided with screw threads. So the double screw thread of the utility model is composed. The screw threads can be symmetrical and with identical format, and the screw threads can also be a coarse screw thread on one side and a fine screw thread on the other side. A bolt is provided with a positive rotation nut and a derotation nut. When in use, the positive rotation nut and the derotation nut which are arranged symmetrically are screwed, so the lock positioning can be achieved. In the strong vibration environment, the corresponding screwed positive rotation and derotation nuts are tighter, which ensures that the lock effect is more reliable. The double screw thread lock-bolt of the utility model adapts to various operating environments and conditions. The positive rotation and the derotation nuts can be screwed in the effective range of the right and left hand threads according to the requirement. The utility model has the advantages of anti-loose, safety, reliability and simple operation.
Description
Technical field: the utility model relates to bolt, relates in particular to two locking thread bolts, mainly is to be used for alternate load or the mechanical vibration position prevents that nut from getting loose, and guarantees safety.
Background technique: the anti-loose technology of screw pair relates generally to three aspects now, and the one, resilient pad is set, make nut remain on pressure state, under the friction torque that pressure produces, prevent relatively rotating of nut, keep anti-loosening working state; The 2nd, cotter pin or series connection wire are set, but, have weakened its due intensity on the contrary because often there is error the position that is provided with; The 3rd, realize lockingly with the way of destroying the screw pair relation, but this way only is suitable for the disposal screw thread pair that can not dismantle again, needing to be not suitable for the environment of adjusting and safeguarding.
The model utility content: the purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of pair of locking thread bolt is provided, and overall structure is simple, and easy accessibility is locking reliable, applied widely.Described in the utility model pair of locking thread bolt includes nuts, screw rod, screw thread and nut and forms.Said nuts adopts the standard piece form of six ribs, and the bolt of nuts and screw rod and prior art is basic identical, even we can say, according to the purposes difference of bolt, the screw rod of polished rod can be set, and the screw rod of polished rod also can be set.Said screw thread is set to just antisymmetric thread forms, that is to say, and on the screw rod of described in the utility model pair of locking thread bolt, screw thread arranged in a crossed manner, just said pair of screw thread of the utility model.Here said screw thread is arranged in a crossed manner, and the screw thread on both sides also can asymmetricly be provided with, Yi Bian promptly be coarse-pitch thread, another side is a fine thread.Cooperate the said two screw threads arranged in a crossed manner of the utility model, on the said bolt of the utility model, be provided with two nuts of dextrorotation and derotation.During use,, can realize locking location automatically with the nut screwing clamping of two symmetries of dextrorotation and derotation.Evidence under the strong vibration environmental conditions, can make between the positive and negative nut of dextrorotation that correspondence tightens and derotation closelyr, has guaranteed that anti-loosening effect is more reliable.As using common bolt, between nut and the fastener plain film can be set, but need not to be provided with compression spring.
Described in the utility model pair of locking thread bolt can adapt to various working environments, so long as in right-and-left threaded effective coverage, can be with the need with positive and negative two nut screwing clampings of dextrorotation and derotation, can realize anti-loosening, safe and reliable, simple to operation.
Description of drawings: accompanying drawing is the structural representation of described in the utility model pair of locking thread bolt.1-nuts 2-screw rod 3-screw thread 4-nut
Embodiment: referring now to accompanying drawing, be described as follows in conjunction with the embodiments: described in the utility model pair of locking thread bolt includes nuts 1, screw rod 2, screw thread 3 and nut 4 and forms.Said nuts 1 and screw rod 2 are basic identical with the bolt of prior art, even we can say, according to the purposes difference of bolt, the screw rod of polished rod can be set, and the screw rod of polished rod also can be set.Said screw thread 3 is set to the form of just antisymmetric screw thread 3, that is to say, and on the screw rod 2 of described in the utility model pair of locking thread bolt, screw thread 3 arranged in a crossed manner, just said pair of screw thread of the utility model.Here said screw thread 3 is arranged in a crossed manner, and the screw thread 3 on both sides also can asymmetricly be provided with, Yi Bian promptly be coarse-pitch thread, another side is a fine thread.Cooperate the said two screw threads arranged in a crossed manner of the utility model, on the said bolt of the utility model, be provided with two nuts of dextrorotation and derotation, nut 4 promptly described in the utility model.During use, the nut 4 of two symmetries of dextrorotation and derotation is tightened, can be realized locking location automatically.Evidence under the strong vibration environmental conditions, can make between the positive and negative nut 4 of dextrorotation that correspondence tightens and derotation closelyr, has guaranteed that anti-loosening effect is more reliable.As using common bolt, between nut and the fastener plain film can be set, but need not to be provided with compression spring.Described in the utility model pair of locking thread bolt can adapt to various working environments, so long as in right-and-left threaded effective coverage, can with the need positive and negative two nuts 4 of dextrorotation and derotation be tightened, can realize anti-loosening, safe and reliable, simple to operation.
Claims (2)
1, two locking thread bolts include nuts (1), screw thread (3) and nut (4) and form, and said nuts (1) adopts the standard piece form of six ribs, it is characterized in that on screw rod (2), and arranged in a crossed manner have a screw thread (3).
2, according to claim 1 pair of locking thread bolt is characterized in that bolt of the present utility model is provided with two nuts (4) of dextrorotation and derotation.
