Abstract
The utility model discloses a double thread deflection type lock nut, which comprises a bolt and a main nut, an eccentric internal thread and a pressure spring chamber are arranged in the main nut, a pressure spring gasket is arranged in the pressure spring chamber, an auxiliary nut is arranged on the eccentric internal thread in the main nut, the auxiliary nut is integrated with the main nut, a standard threaded hole is arranged at the center of the main nut and an auxiliary nut connector, and when the main nut and the auxiliary nut lock bolts, the auxiliary nut is turned to move axle center forward and offset, so as to realize the purpose of anti-loosening.
Description
Technical field
It is a kind of of fastening component that the utility model relates to, particularly two screw thread deflector type lock nuts.
Background technique
In general fastening component, nut is generally and widely component of a kind of purposes.As at machinery, its effect is not embodied in each field such as electric power, automobile, railway, aviation, navigation, military affairs nowhere.Particularly in sharp pounding and irregular powerful fluctuation, nut loosening and obscission often occur, cause dangerous accident to take place, have a strong impact on machinery, the normal operation and the use of each side such as vehicle also cause very big loss to national economy simultaneously.
Because the two screw thread gauche form lock nuts of former patent are in actual use except that anti-loosening property, in its structural design, still there is some deficiency, in order to advance a deficiency of improving in the design for the first time, make its product use more extensive more convenient operation in practice, really reach and alleviate labor strength, prolong life cycle, improve the running time of equipment, create that better economic benefit and social benefit are ad hoc has counted " two screw thread deflector type lock nut ".
Summary of the invention
Main purpose of the present utility model provide a kind of rational in infrastructure, novel, manufacturing is simple, easy to use, strongly professional, standardization level is high, helps promoting the use of " two screw thread deflector type lock nut ".
The utility model " two screw thread deflector type lock nut " is except that the characteristics of " the two screw thread gauche form lock nut " that keep, the outstanding professional and reliability that has embodied " two screw thread deflector type lock nut ", the characteristics that its anti-loosening property is used repeatedly, credibility is higher.
The purpose of the utility model " two screw thread deflector type lock nut " is achieved in that
It comprises the body of bolt and mother nut, is provided with eccentric internal thread of auxiliary connection nut and lock bolt internal thread in the mother nut body and is two screw threads.Secondary nut is provided with eccentric outside thread and is connected one with the eccentric internal thread of mother nut, and secondary nut is provided with locking screw key internal thread and mother nut locking screw key internal thread is same axle center.Equal diameters, with same axle center of external diameter and secondary nut outside thread, mother nut is connected internal thread off-centre with secondary nut, and its eccentricity value is 0.01mm-12mm.
Described, the mother nut inner nut connects an end and is provided with the pressure spring packing ring.
Described, mother nut and secondary nut bulk shape are that N limit type and circular five equilibrium are shaped grooved.
Because the utility model has taked said structure to have the following advantages compared with prior art: have high strength, the powerful anti-loosening property of high reliability: novel and reasonable structure, manufacturing process is simple, and the standardization level height is convenient to large-scale popularization and is adopted.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is a N limit type plan view under the locking state;
Fig. 3 is the shaped grooved plan view of circular five equilibrium under the locking state;
Among the figure: 1, the body of bolt; 2, secondary nut; 3, mother nut; 4, spring washer; 5, secondary nut lockk bolt internal thread; 6, secondary nut outside thread; 7, mother nut auxiliary connection nut 2 internal threads; 8, pressure spring packing ring chamber; 9, mother nut 3 lock bolt internal threads; 10, locking and positioning pin on the mother nut body; 11, locking and positioning groove on the secondary nut body; 12, zero-bit groove.
Embodiment
During manufacturing, in mother nut 3, be provided with auxiliary connection nut 2 internal threads and lock bolt internal thread 9 and be two screw threads.Secondary nut 2 is provided with eccentric outside thread 6 and is connected one with mother nut 3 eccentric internal threads 7, and secondary nut 2 is provided with lock bolt internal thread 5 and is same axle center with mother nut 3 lock bolt internal threads 9, and equal diameters is with the same axle center of external diameter; With secondary nut 2 outside threads 6 mother nuts 3 internal threads 7 off-centre, its eccentricity value is 0.01mm～12mm.Secondary nut 2 is connected locking back drill centers with mother nut 3, attack internal thread, beat " zero " degree groove then, decomposition mother nut 3 and secondary nut 2 pressure spring packing rings are packed in mother nut 3 spring housing, again the mother nut 3 of secondary nut 2 being packed into connects one to " zero " degree groove, when being passed integral nut, the body of bolt 1 reaches user mode, then with secondary nut 2 angle of deflection in the direction of the clock, general deflection angle is between 30 °～75 °, secondary nut 2 internal threads are with the body of bolt 1 locking under the effect of eccentric screw thread, secondary nut 2 outside threads produce secondary locking with mother nut body 3 under the effect of skew, so far make the body of bolt not produce loosening with mother nut 3 secondary nuts 2, reach locking purpose, when unclamping nut, it is concentric with spanner secondary nut 2 to be rotated counterclockwise the secondary nut of " zero " position mother nut groove this moment 32, can withdraw from the body of bolt.
