As shown in the figure, this embodiment comprises locking member and nut 2, is used for locking ball stud 1 and mounting arm 5.Reach by reference to the accompanying drawings correlation technique as can be known, ball stud 1 is provided with installs the conical surface 11, and the end that the conical surface 11 is installed is provided with ball head structure, and the other end is provided with thread section 12.Wherein, ball head structure is installed in the ball-stud socket 4, and can be in ball-stud socket 4 interior rotations.Mounting arm 5 is socketed in to be installed on the conical surface 11, and nut 2 is screwed onto on the thread section 12, and the screwing force of nut 2 fits tightly the conical surface that the conical surface 11 and mounting arm 5 are installed.Locking member is installed on the ball stud 1, and places between mounting arm 5 and the nut 2, and in the process that nut 2 is tightened or unscrewed, locking member can with mounting arm 5 and ball stud 1 locking, can not rotate with nut 2 ball stud 1.
Preferably, referring to Fig. 3-Fig. 7, locking member further is lock washer 3, and lock washer 3 is socketed on the thread section 12, and the inner edge of lock washer 3 is provided with the first claw 31, and outer rim is provided with the second claw 32.Be provided with vertically the first draw-in groove 121 on the outer wall of thread section 12, and the first draw-in groove 121 runs through the end face of thread section 12.Mounting arm 5 is provided with the end face 52 that the second draw-in groove 51, the second draw-in grooves 51 run through mounting arm near the outer wall of end face 52.And the first claw 31 on the lock washer 3 is held in the first draw-in groove 121 on the thread section 12, is held in the second draw-in groove 51 after the second claw 32 bendings on the lock washer 3.Can be found out by said structure, the first claw 31 is relative fixing with mounting arm 5 with ball stud 1 with the second claw 32.
Certainly, lock washer 3 also can be socketed on the mounting arm 11, and the first draw-in groove 121 extends on the mounting arm 11 along thread section 12, and the first claw 31 of lock washer 3 is held in the first draw-in groove 121 that extends on the mounting arm 11.
Further preferably, referring to Fig. 4, Fig. 7, lock washer 3 can further include the 3rd claw 33, the 3rd claw 33 is connected to the outer rim of lock washer 3, and, nut 2 is hexagon nut, and any one outer wall with hexagon nut 2 after 33 bendings of the 3rd claw fits, and prevents that nut 2 is loosening.
It can also be seen that from Fig. 3, Fig. 4, Fig. 7, the second claw 32 and the 3rd claw 33 are the long strip sheet structure, during installation, will be held in the second draw-in groove 51 after 32 bendings of the second claw, will fit with any one outer wall of nut 2 after 33 bendings of the 3rd claw.Certainly, the second claw 32 also can be processed as the L-type structure, has saved the bending operation in the installation process.
In the present embodiment, shaping structure can be processed as one lock washer 3, the first claw 31, the second claw 32 and the 3rd claw 33, the shaping structure that also lock washer 3, the first claw 31 and the second claw 32 can be processed as one is so that lock washer has better rigidity and intensity.
During assembling, first ball stud 1 and ball-stud socket 4 are assembled into one, the installation conical surface 11 with ball stud 1 inserts in the taper hole of mounting arm 5 again, the first claw 31 on lock washer 3 inner edges is held in the first draw-in groove 121 of thread section 12 again, at this moment, ball stud 1 still can rotate in ball-stud socket 4.Lock washer 3 and ball stud 1 are rotated together, make the second claw 32 over against the second draw-in groove 51 of mounting arm 5, will stick in the second draw-in groove 51 after 32 bendings of the second claw, at this moment, ball stud 1 can not relatively rotate with mounting arm 5.Then nut 2 is installed on the thread section 12, during installation, can be by pneumatic impact wrench or manually tighten, in the rundown process, ball stud 1 can not rotate, and is fitted on a certain outer wall of nut 2 after the 3rd claw 33 bendings with lock washer 3 after tightening, and prevents that nut 2 is loosening.During dismounting, first bending is folded flat to the 3rd claw 33 on nut 2 outer wall, backs out nut 2, take off again lock washer 3, separate at last ball stud 1 and mounting arm 5.
Compare with existing locking mechanism, the present embodiment has following advantage:
1) lock washer has prevented relatively rotating of ball stud and mounting arm, when installation and removal, can not occur because the situation that can't tighten He can't dismantle that ball stud causes along with nut rotates together.
2) the present embodiment prevents nut loosening by the 3rd claw locking nut, and is simple in structure.
Embodiment two:
Referring to Fig. 8, Fig. 8 is the utility model ball stud retention mechanism the second embodiment's structural representation.
The present embodiment and embodiment's one difference is: the locking mechanism of nut 2.
Referring to Fig. 8, the inner edge of the lock washer 3 in the present embodiment is provided with the first claw 31, and outer rim is provided with the second claw 32.The first claw 31 is held in the first draw-in groove 121 on the thread section 12, is held in after 32 bendings of the second claw in the second draw-in groove 51 on the mounting arm 5, and dependency structure gets final product with reference to embodiment one, and the present embodiment does not repeat them here.
In the present embodiment, nut 2 is slotted nut, and by cotter pin 6 slotted nut is locked on the thread section 12.Particularly: radially have through hole on the thread section 12, the through hole on slotted nut and the thread section 12 is passed in cotter pin 6, and slotted nut is locked on the ball stud 1, prevents that it is loosening.
Lock washer in the present embodiment can not relatively rotate ball stud and mounting arm, and when the installation and removal nut, ball stud can not rotate with nut.In addition, the present embodiment by cotter pin with nut check on ball stud, simple in structure, easy for installation.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
