Description

A kind of Anti-loose fastener
Technical field
The present invention relates to technical field of fastening, and in particular to a kind of Anti-loose fastener.
Background technique
Fastener is widely used mechanical basic part, is widely used in rail traffic, aerospace, car lift on lift off ship Multiple objects can be not only fastenedly connected by the use in the heavy equipments such as oceangoing ship, wind-power electricity generation field, fastener, moreover it is possible to transmit lotus It carries, quality and reliability plays an important role to the safety of structure.Fastener often produces after by Fatigue Load Raw loosening, even failure phenomenon, seriously affect integrally-built safety;In addition fastener is also widely present corrosion problem, can lead The intensity of fastener is caused to be affected, in addition the corrosion problem of fastener will lead to bolts and nuts adhesion, it is not easy to dismantle.
General fastener locking moves measure, and certain anti-loosening effect, but this can be such as played using double nut fixation Kind method is only limitted to more small and weak loosening, can not play strong pre- anti-loosening effect;Sealant tape pair and water pipe The small-sized bolts such as installation have preferable effect, but poor to high-intensitive high-frequency vibration resistance;For the rust of fastener Erosion problem, using electrogalvanizing mode due to cost height, the corrosion resistance of coating flash plating is poor.It is dynamic for existing fastener locking With the drawbacks described above of anti-corrosion measure, we need it is a kind of satisfaction can make to set under high-strength load and outdoor environment corrosion function The standby measure worked normally.
Summary of the invention
The purpose of the present invention is to provide a kind of Anti-loose fasteners, with overcome the deficiencies in the prior art, especially in height It can work normally under strong load and outdoor environment eating condition.
The purpose of the present invention can be realized by following technical proposals:
A kind of Anti-loose fastener, the device include bolt, nut;The bolt includes knob, fixing groove, shank of bolt, tooth Take turns drive rod, sawtooth bolt, bolt movable span, lubricating oil;The bolts and nuts are connect by screw thread with sawtooth bolt;Institute It is tubular gap inside the shank of bolt stated, nut interior is equipped with latch groove;The tubular aperture diameter is omited than gear-driving rod Greatly, the gap between shank of bolt and gear-driving rod is by oil refill, and lubricating oil can be flow to by latch groove bolt with The thread space of nut;The knob can be such that gear-driving rod rotates, and drive the translation of sawtooth bolt by gear, knob can It slides up and down, and is may be stuck in fixing groove along gear-driving rod top.
As preferred design scheme, the gear-driving rod and sawtooth bolt by gear drive make sawtooth bolt to Different directions are mobile.
As preferred design scheme, the bolt movable span is identical as bolt slot aperture and inserts slightly larger than sawtooth Pin.
As preferred design scheme, the fixing groove is more bigger than cuboid knob in cuboid empty slot and fixing groove can Knob is prevented, while fixing groove also can be used as at lubricating oil addition.
The present invention has the advantages that
(1) sawtooth bolt is moved to latch groove using gear drive principle by gear-driving rod, can effectively prevent bolts and nuts it Between generate displacement, and then ensure that the overall work of fastener is horizontal.
(2) gap between shank of bolt and gear-driving rod is by oil refill, and lubricating oil can be flowed by latch groove To the thread space of bolts and nuts, fastener internal corrosion can be effectively prevent.
(3) setting of knob and fixing groove can effectively prevent the rotation in violent load action lower gear drive rod.
Detailed description of the invention
For the clearer technical solution for illustrating this patent embodiment, spy draws following pictures and is introduced.
Fig. 1 is overall structure diagram of the invention.
Fig. 2 is forward sight planing surface figure when gear-driving rod and sawtooth latch structure of the invention work.
Fig. 3 is vertical view planing surface figure when gear-driving rod and sawtooth latch structure of the invention work.
Fig. 4 is structural schematic diagram when knob of the invention is stuck in fixing groove.
Appended drawing reference summarizes: 100- bolt, 110- knob, 120- fixing groove, 130- shank of bolt, 140- gear-driving rod, 150- sawtooth bolt, 160- bolt movable span, 170- lubricating oil, 200- nut, 210- latch groove.
Specific embodiment
It elaborates in conjunction with the accompanying drawings and embodiments to the present invention, embodiment described below is a part of the invention Embodiment.On the basis of the embodiment of the present invention, those skilled in the art are not making other creative works under the premise of institute The embodiment obtained is all within the scope of protection of the invention.
Embodiment 1:
As shown in Figs 1-4, the embodiment of the invention provides a kind of Anti-loose fastener, which includes bolt 100, nut 200; The bolt includes knob 110, fixing groove 120, shank of bolt 130, gear-driving rod 140, sawtooth bolt 150, bolt activity Hole 160, lubricating oil 170;The bolt 100 is connect by screw thread with sawtooth bolt 150 with nut 200;The shank of bolt 130 inside are tubular gap, are equipped with latch groove 210 inside nut 200;The tubular aperture diameter is than gear-driving rod 140 Bigger, the gap between shank of bolt 130 and gear-driving rod 140 is filled by lubricating oil 170, and lubricating oil 170 can pass through bolt Slot 210 flow to the thread space of bolt 100 Yu nut 200;The knob 110 can be such that gear-driving rod 140 rotates, and lead to Crossing gear drives sawtooth bolt 150 to be translatable, and knob 110 can be slided up and down along 140 top of gear-driving rod, and may be stuck in fixing groove In 120.
As shown in Figure 2,3, gear-driving rod 140 makes sawtooth bolt 150 to difference with sawtooth bolt 150 by gear drive Direction is mobile, and bolt movable span 160 is identical as 210 aperture of latch groove and is slightly larger than sawtooth bolt 150, when bolt 100 is screwed to Fixed position, bolt movable span 160 are precisely aligned with latch groove 210;Rotating clockwise knob 110 can be by sawtooth bolt 150 It withdraws, sawtooth bolt 150 can be screwed out by rotating knob 110 counterclockwise.
As shown in figure 4, fixing groove 120 is more bigger than the knob 110 of cuboid in cuboid empty slot, fixing groove 120 can be prevented Knob 110 rotates, and further limits the displacement of sawtooth bolt 150, achievees the purpose that anti-loosening, while fixing groove 120 can also be made At 170 addition of lubricating oil.
