Description
Technical field
The utility model belongs to technical field of fastening, especially relates to the anti-loose mechanical retention mechanism of a kind of self tightening.
Background technique
Screw pair retention mechanism is a kind of retention mechanism of common screw-thread fit, the modal fastening connection piece cooperatively interacted for bolts and nuts, realizes being threaded to machinery link by the screw thread of bolt.The switching performance of bolts and nuts is good, structure is simple, be widely used in technical field of mechanical equipment, but bolts and nuts also exist the defect easily loosened, the gap shaking link along with equipment frequently increases, and causes bolts and nuts to loosen, even comes off, the mutual break-off of connecting body is easily there is, serious easy generation security incident when like this some being mechanically connected.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses a kind of compact form Anti-loose bolt [application number: 201220063479.X] mutually, is made up of screw rod, inner nut, outer nut.Screw flight is forward and reverse screw thread, and the internal thread of inner nut is forward screw thread, and the internal thread of outer nut is reverse thread.Inner nut and outer nut 2 ~ 12 anti-slip tanks are provided with to end face.Anti-slip tank is the structure raised gradually counterclockwise.
Such scheme improves the problem easily loosened when existing bolts and nuts connect to a certain extent, although such scheme at inner nut and outer nut to end face being provided with several anti-slip tanks, but the screw thread starting point of inner nut, outer nut, bolt is all uncertain, anti-slip tank is that very difficult realization is stuck object mutually.Even if can accidentally be stuck, but, it is low still to there is join strength in the program, when shaking large, inner nut and outer nut easily occur that gap or inner nut easily promote outer nut and to shrink back the problem causing loosening between inner nut and connecting body, and finally cause outer nut and inner nut to depart from bolt situation occurring.
Model utility content
The purpose of this utility model is for the problems referred to above, provide a kind of reasonable in design, structure simple, has the anti-loose mechanical retention mechanism of self tightening of anti-loose function.
For achieving the above object, the utility model have employed following technical proposal: the anti-loose mechanical retention mechanism of this self tightening, comprise the body of bolt, the described body of bolt have two thread sections be connected with anti-loosing nut screw thread with gland nut respectively, and the hand of spiral of two thread sections is contrary, it is characterized in that, the described body of bolt is arranged with the regulating ring between gland nut and anti-loosing nut, described gland nut is connected by one-way rotation structure with between regulating ring, locate by one-way rotation structure and regulating ring are circumferential towards the gland nut described in when the circumference rotational motion of anti-loosing nut side or movement tendency when gland nut has to rotate relative to regulating ring circumference away from the gland nut described in when the circumference rotational motion of anti-loosing nut side or movement tendency and to have when gland nut, be provided with between described regulating ring and anti-loosing nut and can make the circumferential positioning structure that regulating ring and anti-loosing nut circumference are located and the axial positioning structure that can make regulating ring and anti-loosing nut axially locating, also shock-damping structure is provided with between described regulating ring and anti-loosing nut.During use, the effect of axial positioning structure is when gland nut moves down, due to the existence of axial positioning structure, due to regulating ring and anti-loosing nut axially locating, such regulating ring can not move down along with gravity, when gland nut towards away from anti-loosing nut side circumference rotational motion or movement tendency time described in gland nut can relative to regulating ring circumference rotate, namely when gland nut is towards the motion of locking direction, gland nut can rotate relative to regulating ring circumference, gland nut and regulating ring are separated from each other, when compacted object exists, this athletic meeting is prevented from certain interval, anti-loosing nut is because one-way rotation structure can not depart from the body of bolt, locate by one-way rotation structure and regulating ring are circumferential towards the gland nut described in when the circumference rotational motion of anti-loosing nut side or movement tendency when gland nut has, simultaneously, because regulating ring and anti-loosing nut are positioned together by circumferential positioning structure and axial positioning structure, and gland nut screw thread and anti-loosing nut screw thread are opposite direction screw threads, make gland nut cannot rotate towards anti-loosing nut side circumference like this, but the rotation potential energy of gland nut gives anti-loosing nut by one-way rotation structure through regulating ring transmission, drive anti-loosing nut to the circumferential rotational motion of gland nut side or movement tendency, gland nut is so just made to be in continuous self-tightening process all the time, then the auto-lock function of mechanism is realized, mutually locate due to anti-loosing nut and regulating ring simultaneously and make anti-loosing nut to depart from the body of bolt due to the existence of one-way rotation structure.
In the anti-loose mechanical retention mechanism of above-mentioned self tightening, described one-way rotation structure comprises and is arranged on gland nut one end and the compression helicoid distributed in the shape of a spiral and be arranged on regulating ring one end and the cooperation helicoid distributed in the shape of a spiral, described compression helicoid with compress helicoid and match and forms one-way rotation helicoid pair.When gland nut has towards the circumference rotational motion of anti-loosing nut side or movement tendency, due to compression helicoid here with coordinate helicoid mutually against can make gland nut and regulating ring circumference locate, obviously, the structure of one-way rotation structure is varied, and those skilled in the art can also select other structures.
