Abstract
The utility model relates to an anti-loosening bolt. The anti-looseness bolt comprises a screw rod with a pin groove at one end, and a nut sleeved on the screw rod; a wedge block is embedded in the pin groove; and a spring ring is sleeved on the screw rod between the nut and the wedge block. According to the utility model, the structure of the bolt is improved, so that the bolt has an anti-loosening function and has the advantages of convenience in installation and processing, and reusability.
Description
Technical field
The utility model relates to a kind of anti-loose bolt.
Technical background
Though the bolt performance is good, and is simple in structure, reliability is high, is widely used, and exists easily loosening this problem, because link exists gap and frequent vibrations, all is the reason that causes bolt looseness, even comes off.In the connection of power grid iron tower, what adopt basically is that bolt connects at present, but because iron tower receives the influence of factor of natural environment for a long time; Cause iron tower to produce frequent vibrations, the bolt that accumulates over a long period will produce loosening, if under boisterous effects such as strong wind; More can aggravate bolt gets loose; Cause the part angle steel to come off, iron tower structural instability and serious accidents such as tower take place down directly endangers power grid security.
The model utility content
The utility model technical problem to be solved provides a kind of reliable performance, is easy to processing, also can effectively overcomes the easy loosening problem of nut, reusable anti-loose bolt.
The utility model adopts following technological scheme:
The utility model has the screw rod of cotter way by an end and the nut that is sleeved on the screw rod constitutes, and is equipped with voussoir on the described cotter way, on the screw rod between nut and the voussoir, is set with spring ring.
The good effect of the utility model is following:
The utility model is processed the cotter way of certain-length on screw rod, the position of this cotter way does not influence the intensity of nut working position screw rod outside the nut working position.Behind the nut installation in position, the screw jacket upper spring circle that is stretching out.This spring ring one end contacts with nut, and the end voussoir interior with embedding cotter way contacts, and voussoir one end contacts with spring ring, and an end contacts with the cotter way outer end inner wall.Satisfy spring ring during installation and be in the state of killing, make nut to end face and cotter way to there being huge extra pretightening force between the end face.This power finally makes nut can not produce moving laterally.The utility model improves bolt arrangement, makes it possess locking function, and processing, easy for installation, reusable.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model wedge structure schematic representation.
In the accompanying drawings, 1 screw rod, 1-1 screw thread, 1-2 cotter way, 2 nuts, 3 spring rings, 4 voussoirs.
Embodiment
Like accompanying drawing 1, shown in 2, the utility model has the screw rod 1 of cotter way 1-2 by an end and the nut 2 that is sleeved on the screw rod 1 constitutes, and is equipped with voussoir 4 on the described cotter way 1-2, on the screw rod 1 between nut 2 and the voussoir 4, is set with spring ring 3.The effect of spring ring 3 is that nut 2 does not reach best operational position when preventing to install, because vibrations may produce moving to the inside, causes additional pretightening force to lose efficacy in the work.The existence of spring ring 3 then can be avoided this situation.When nut 2 produces moving to the inside, spring ring 3 elongations, additional pretightening force can reduce, and is zero but can not fall sharply.This had both guaranteed to provide additional pretightening force, had guaranteed that also voussoir 4 can loose or dislocation.
Screw rod 1 passes link, uses nut 2 link of screwing, and uses the utility model, behind nut 2 installation in position, at the screw rod that stretches out 1 overcoat upper spring circle 3.In voussoir 4 wedging cotter way 1-2.Voussoir 4 one ends contact with spring ring 3, and an end contacts with cotter way 1-2 outer end inner wall.
The utility model improves bolt arrangement, makes it possess locking function, and processing, easy for installation, reusable.
