State in order to ensure with maintaining above-mentioned conventionally upper and lower two nuts and setting, is carved with station location marker (3), (4) in the corresponding side of upper and lower two nuts.In order to prevent because casual external force causes the state that upper and lower two nuts set conventionally destroyed, between upper cap nut (1) and lower nut (2), be provided with a spring (5), this spring (5) can remain afore mentioned rules interval (15) by the interval of the bottom of the top of eccentric circle tubular jut (11) and large diameter tapped hole (14).And; in the situation that locking mechanism is subject to external force, spring (5) can play the effect of buffering, assurance upper cap nut (1) that can be to a certain degree; the relative position of lower nut (2) and bolt (9) can not be changed, and can also play the not impaired effect of protection bolt.
With the state that upper and lower two nuts set conventionally, upper and lower two nuts are locked to bolt (9) simultaneously, after bolt (9) produces required axle power, only upper cap nut phase (1) is screwed in to a specific angle to lower nut (2) and make to produce coupling mechanism force perpendicular to the bias of axis direction.Simultaneously, thread pitch and first, second central, threaded hole (10) due to large outer-diameter threads portion (12) and large diameter tapped hole (14), (13) thread pitch is different, can make lower nut bolt be produced on axis direction to the coupling mechanism force of an extruding.The three-dimensional coupling mechanism force producing at the both direction of axis direction and axle center Vertical direction guarantees that whole fastening structure can not get loose phenomenon.Because the axle power of fastening structure is produced when the locking fixation by lower nut (2) and bolt (9), when playing a role, three-dimensional coupling mechanism force can't bring any impact to the axle power having produced, so guaranteed stability and the axle power controllability of whole fastening structure.Add the powerful anti-loosing effect of three-dimensional coupling mechanism force, and the buffer protection effect of spring (5), even if can guarantee under the Environmental Conditions of very severe, whole fastening structure all can keep stable safe condition for a long time.
If by upper and lower two nuts (1), (2) after opening, only need first spring to be placed on lower nut (2), upper cap nut (1) is screwed into lower nut (2) to the visual consistent state that is in of polygonal appearance (take hexagonal in figure as example) of two nuts, and first of upper and lower two nuts, the second mark is simultaneously also in consistency from top to bottom state, and the extruding that spring (5) is just subject to upper cap nut (1) and lower nut (2) starts to produce elastic force, at this moment go up, lower two nuts (1), (2) first, the second central, threaded hole (10), (13) centerline is on same straight line, screw thread is in consistent breakthrough status, nut group is returned to again and conventionally sets state.
The following describes as concrete effect and the effect of the lock nut group of said structure.
As shown in Figure 7, bolt (9) is inserted to fixture one (6) and fixture two (7), and by screw thread and nut group (8) locking.The meaning of locking is herein that upper cap nut (1) and lower nut (2) state position sign 3,4 is as shown in Figure 1 in the situation that conventionally sets state and screws in bolt (9) and make that lock nut group (8) is upper produces required axle power.After bolt (9) produces required axle power, the angle that only the relative lower nut (2) of upper cap nut (1) is screwed in to a regulation makes to produce coupling mechanism force perpendicular to the bias of axis direction.Simultaneously, thread pitch and first, second central, threaded hole (10) due to large outer-diameter threads portion (12) and large diameter tapped hole (14), (13) thread pitch is different, can make upper and lower nut (1), (2) on axis direction, produce the coupling mechanism force of an extruding to bolt (9).The three-dimensional coupling mechanism force producing at the both direction of axis direction and axle center Vertical direction guarantees that the whole structure that is locked can not get loose phenomenon.
In addition, in order to ensure the state with maintaining above-mentioned conventionally upper and lower two nuts and setting, in the corresponding side of upper and lower two nuts, be carved with the first mark (3), the second mark (4), in order to prevent that a spring (5) is established in the gap between upper cap nut (1) and lower nut (2) because casual external force causes the state that upper and lower two nuts set conventionally destroyed.With the locking of the state that conventionally sets of upper and lower two nuts with unload all very convenient easy to operate.
Above preferably mode of execution of the present utility model is illustrated, but the utility model is not limited to this, within not departing from the scope of its aim, can carries out various changes and implement.
