Abstract
The utility model provides a non-removable antitheft self-lock bolt and nut components which can adjust the components and consists of a bolt and a nut. The bolt is opened with a ratchet slot, and the nut is internally provided with a pawl and can fasten the object by rotating clockwise; when adjusting an object, like a common nut, the utility model can repeatedly loosen, remove and fasten; when affirming the object, no adjustment is needed any more, the utility model fastens the nut, and after that, knocks down the limit cap; moreover, the nut can not rotate backward. Being safe and reliable, the utility model has simple operation and convenient using as well as high self-lock, anti-loose and antitheft performances, thus is an anti-loose and antitheft self-lock bolt and nut component which are extensively used in the occasions with components not needing removing after being fastened once in various industries.
Description
The utility model relates to a kind of bolt, nut fastener, is in particular theftproof self-locking bolt, nut assembly that a kind of object can be adjusted, can not demolition.
According to the actual job needs, some object is through trial assembly, and after its position, the service behaviour adjustment correctly, it is fastening to use bolt, nut that object is forever connected, and does not allow dismounting.Present used bolt, nut assembly, in object trial assembly adjustment process, repeated removal repeatedly, when the object position, after the service behaviour adjustment is correct, can be reliably that it is fastening, do not allow the technical requirements of dismantling but can not satisfy.
In order to solve bolt, nut in connecting fastening object process, but repeated removal, again can be after its position, service behaviour adjustment are correct with its permanent fastening and satisfied technical requirements that can not demolition, people have designed some non-removable bolts, nut assembly.A kind of " double roller pin corresponding anti-theft bolt " disclosed as Chinese utility model patent (patent No. 99210915), it is made up of screw rod and anti-theft nut, center hole outside symmetry offers two half wedge type grooves on anti-theft nut, in half wedge type groove, needle roller is housed, the port of half wedge type groove is plugged with cock cap, because the effect of two needle rollers increases nut despining moment and is twice.This kind anti-theft bolt, nut assembly do not solve the problems of the technologies described above preferably yet.
The purpose of this utility model is at deficiency of the prior art, but purport provides a kind of bolt, nut repeated removal in connecting fastening object process, again can it is permanent fastening and object that satisfy non-dismountable technical requirements can be adjusted, non-removable anti-theft self-locking screw, nut assembly after object position, service behaviour adjustment are correct.
The purpose of this utility model realizes in the following manner: object can be adjusted, the non-removable anti-theft self-locking screw, nut assembly, by bolt 1, nut 3 is formed, it is characterized in that having a ratchet-shaped groove 4 at least along bolt 1 axial direction effective thread length somewhere, nut 3 is shaped on a ratchet connected in star 11 at least, groove has towards flank of thread opening 12, locking pin slotted eye 5 passes in the groove from nut 3 outer walls, bearing pin 10 is housed in the groove, ratchet 6 is drilled with hole 7,9, opening slot 8, hole 7 is hinged with bearing pin 10, ratchet 6 is that the center of circle can be swung in ratchet connected in star 11 with bearing pin 10, spring 13 1 ends and opening slot 8 are affixed, one end slides at ratchet connected in star 11 inwalls, and locking pin 14 1 ends have limited cap 15, one ends and hole 9 hinged.
The utility model is described in detail in detail with reference to the accompanying drawings.
Fig. 1 the utility model shape assumption diagram
Fig. 2 bolt ratchet-shaped groove schematic representation
Fig. 3 locking pin slotted eye position view
Fig. 4 capping outline drawing
Fig. 5 nut K is to partial enlarged drawing
Fig. 6 pawl structures schematic representation
Fig. 7 ratchet connected in star schematic representation
Fig. 8 spring, locking pin mounting point schematic representation
With reference to Fig. 5,6,7,8, ratchet connected in star 11 is built in nut 3 end faces, locking pin 14 diameters are less than locking pin slotted eye 5 diameters, limited cap 15 diameters are greater than locking pin slotted eye 5 diameters, make it to expose at nut 3 outer walls, under the effect of limited cap 15, ratchet 6 is locked at the bottom of nut 3 internal threads outside the footpath by locking pin 14.
With reference to Fig. 1,4, capping 2 covers in locking pin slotted eye 5, ratchet 6, bearing pin 10, ratchet connected in star 11, spring 13, locking pin 14 and connects firmly with nut 3 end faces.
The utility model is to use like this: after needing fastening object to load onto bolt 1, nut 3 there is capping one end towards bolt thread and clockwise direction rotation, make the capping end face compress the purpose that object reaches fastening object, when object need be adjusted, nut 3 is the same with plain nut, can repeat to become flexible, dismantle, screw.When confirming that object no longer needs to adjust, after screwing nut, knock out the limited cap 15 that exposes at nut outer wall, 14 pairs of ratchets 6 of locking pin this moment lose lock function, under the elastic reaction of spring 13, the ratchet blade tooth is pressed to ratchet-shaped groove 4 on the bolt by opening 12, but as the little swivel nut of needs clockwise direction, makes ratchet blade tooth and ratchet-shaped groove correct engagement.This moment, nut can only rotate by clockwise direction under the interaction of ratchet and ratchet, and any existing instrument all can not make the normal rotation counterclockwise of nut and be removed.
The utility model is simple to operate, easy to use, safe and reliable, self-locking, locking, theftproof performance is strong, in industries such as water conservancy, electric power, machinery, traffic, communications, be widely used locking, the theftproof self-locking bolt in the place that need not dismantle after fastening of object, nut assembly.
