Abstract
The utility model provides a kind of Combined locknut preventing loosening voluntarily on bolt, comprises tightening nut, lock washer, spring washer and gland nut.Its feature is: limited location groove on tightening nut, lock washer has stop ear and retaining ear, gland nut has slideproof tooth.After the workpiece on bolt being tightened with tightening nut, be inserted in lock washer and spring washer more successively and make the stop ear on lock washer embed in the limited impression of tightening nut, precession tighten gland nut again, namely retaining ear on lock washer is inserted in the teeth groove of gland nut slideproof tooth, make the tightening nut after tightening, lock washer, spring washer and gland nut form a fastening entirety, and frictional force is very large all the time between the screw thread of this entirety and bolt, so this Combined locknut plays good anti-loosing effect, and it is simple to operate, reusable.
Description
(1) technical field
The utility model relates to a kind of fastening piece, particularly a kind of Combined locknut.
(2) background technique
The application of nut is very extensive, but plain nut is without locking functions, can be more and more loose when the factors such as vibrated, impact affects, the existing anti-loosing effect had with the nut of locking functions is not good, some operation inconvenience, what have can not reuse, and is not all very practical.
(3) summary of the invention
In order to make up the deficiency of existing lock nut, the utility model provides a kind of Combined locknut, practical, and anti-loosing effect is good.
The utility model is achieved through the following technical solutions:
A kind of Combined locknut, comprises tightening nut, lock washer, spring washer and gland nut.Its feature is: limited location groove on tightening nut, lock washer has stop ear and retaining ear, gland nut has slideproof tooth.
The lower end surface of tightening nut described in the utility model, with flange part, the cylindrical side of flange part has the limited impression corresponding with the stop ear of lock washer.
The stop ear of lock washer described in the utility model and retaining ear be by the square evagination of the radial direction of two on lock washer cylindrical in the axial direction each other reverse side roll over an angle of 90 degrees form, after lock washer is inserted in bolt, its stop ear can embed just to condition each other in the limited impression of tightening nut, and its retaining ear can insert in the teeth groove of gland nut slideproof tooth and get loose to prevent gland nut from turning round.The effect of described spring washer is to provide pretightening force, the external diameter of spring washer is less than the external diameter of lock washer, insert in the teeth groove of gland nut slideproof tooth with the external diameter making the retaining ear of lock washer can cross spring washer, spring washer and lock washer are all be made up of the metallic material that elasticity is strong.
The upper-end surface of gland nut described in the utility model is with flange part, and the cylindrical side of flange part is carved with the zigzag fashion slideproof tooth of uniformly continous for one week, the trend of slideproof tooth and gland nut to screw direction contrary.
The beneficial effects of the utility model are, the nut freely rotated due to two on bolt after holding out against mutually between two nuts end thrust increase, so axial force increases and makes two nuts become and is difficult to rotate between the screw thread of two nuts and bolt, therefore after gland nut described in the utility model holds out against tightening nut, recycling lock washer makes relative distance between tightening nut and gland nut remain unchanged, then tightening nut, lock washer, namely elastic washer and gland nut form a fastening entirety on bolt, and frictional force is very large all the time between the screw thread of this entirety and bolt, thus more lasting anti-loosing effect is served.The utility model is simple to operate, reusable, and anti-loosing effect is good.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of the utility model using state.
Fig. 2 is the schematic appearance of the utility model tightening nut.
Fig. 3 is the schematic appearance of the utility model lock washer.
Fig. 4 is the schematic appearance of the utility model gland nut.
In figure, 1 tightening nut, 2 lock washers, 3 spring washers, 4 gland nuts, 5 limited impressions, 6 slideproof tooth, 7 stop ears, 8 retaining ears, 9 bolts, 10 workpiece.
(5) embodiment
A kind of Combined locknut, comprises tightening nut 1, lock washer 2, spring washer 3 and gland nut 4.The lower end surface of tightening nut 1, with flange part, the cylindrical side of flange part has the limited impression 5 corresponding with the stop ear 7 of lock washer 2.Two square evaginations of radial direction on lock washer 2 cylindrical are the stop of reverse side folding an angle of 90 degrees formation each other ear 7 and retaining ear 8 in the axial direction.The upper-end surface of gland nut 4 is with flange part, and the cylindrical side of flange part is carved with the zigzag fashion slideproof tooth 6 of uniformly continous for one week, the trend of slideproof tooth 6 and gland nut 4 to screw direction contrary.The external diameter of spring washer 3 is less than the external diameter of lock washer 2, and insert in the teeth groove of the slideproof tooth 6 of gland nut 4 with the external diameter making the retaining ear 8 of lock washer 2 can cross spring washer 3, spring washer 3 and lock washer 2 are all be made up of the metallic material that elasticity is strong.
First with tightening nut 1 workpiece 10 on bolt 9 tightened during use and make the lower end surface of tightening nut 1 outside, successively lock washer 2 and spring washer 3 be inserted in bolt 9 again and make the stop ear 7 of lock washer 2 embed in the limited impression 5 of tightening nut 1, then precession gland nut 4 make its upper-end surface inwards, the retaining ear 8 suitably levering up lock washer 2 when retaining ear 8 close to lock washer 2 of the slideproof tooth 6 of gland nut 4 continues precession to allow gland nut 4, its meeting of 8, the retaining ear of release lock washer 2 constantly slip over from the slideproof tooth 6 of gland nut 4 with the precession of gland nut 4 under natural resiliency, when lock washer 2 after gland nut 4 is suitably screwed retaining ear 8 by be inserted in the slideproof tooth 6 of gland nut 4 teeth groove in prevent gland nut 4 from turning round, therefore the tightening nut 1 after tightening, lock washer 2, spring washer 3 and gland nut 4 form a fastening entirety, and frictional force between this overall and bolt 9 screw thread is very large all the time, serve more lasting anti-loosing effect.
During dismounting, first the retaining ear 8 of lock washer 2 prized from the teeth groove of the slideproof tooth 6 of gland nut 4 and screw out gland nut 4 simultaneously, then taking out spring washer 3, lock washer 2, screwing out tightening nut 1.
