Abstract
The utility model discloses a lock nut capable of adjusting retaining force. The lock nut comprises a polygonal body provided with a round threaded hole, a tube body is arranged at the upper end of the body and provided with the round threaded hole in accordance with the body, concave pits are formed in the side wall of the body, and flanges are arranged on the corresponding wall of the round threaded hole. An elastic tongue-shaped body is arranged on the side wall of the tube body and extends into the round hole in the radial direction. Due to the fact that multiple friction force can be generated, it can be guaranteed that the lock not does not loosen under the special conditions (strong vibration), and the lock nut is safe and reliable in usage and can be used repeatedly.
Description
Technical field
The utility model belongs to fastening piece, is specifically related to a kind of lock nut that can regulate retaining power.
Background technique
Mechanical device particularly vibrative mechanical device must be considered the loosening problem of fastening piece, otherwise fastening piece can get loose voluntarily in strenuous vibration, causes parts or complete device damage, disintegrating even leads to a disaster.For fear of becoming flexible of fastening piece, common way is to adopt lock washer.Traditional lock washer mainly relies on frictional force to reach anti-loosing effect, in low vibrations, underloading, under state at the uniform velocity, anti-loosing effect can meet the demands, but at strong motion, high loading, under rapid movement state, do not reach complete anti-loosing effect, just extended the time that nut and bolt get loose voluntarily.
Model utility content
The purpose of this utility model is to provide the lock nut that can regulate retaining power that a kind of anti-loosing effect is good.
The technological scheme that realizes the employing of the utility model object is as follows:
Can regulate the lock nut of retaining power, comprise the polygonal body of establishing thread circle hole, the upper end of described body is provided with a cylindrical shell, cylindrical shell adopts the thread circle hole consistent with body, on the sidewall of described body, be provided with pit and be provided with flange on corresponding threaded circular hole wall, on the sidewall of described cylindrical shell, be provided with the elasticity colulus radially stretching in circular hole.
Described elasticity colulus is to be positioned at sustained height but two of opposite direction.
The top of crossing described elasticity colulus on the sidewall of described cylindrical shell has in-line otch.
The lower end of described body is provided with movable saddle shaped washer.
The utility model adopts after said structure, and bolt can utilize elasticity colulus radially applying while being used in conjunction with and adjusting nut and bolt between frictional force, utilization is formed on flange corresponding on threaded circular hole wall by extruding pit and forms the frictional force between nut and bolt cusp on body sidewall, utilize in-line otch axial compression in advance distortion, in nut screwing clamping process, further increase the frictional force between nut and bolt tooth distance, saddle shaped washer also can produce distortion and increase the elastic compression power between nut and workpiece when nut screwing clamping.The amplitude stretching in circular hole by control elasticity colulus can regulate the locking power of retaining.The utility model, owing to can producing multiple frictional force and elastic compression power, can guarantee that it is not loosening, safe and reliable in special operating mode (strong vibration), and reusable, economical convenient.
Below in conjunction with accompanying drawing, further illustrate the technical solution of the utility model.

Fig. 2 is that the AA of Fig. 1 is to view.
Fig. 3 is that the BB of Fig. 1 is to view.
Fig. 4 is different structure schematic diagram of the present utility model.
Embodiment
Referring to Fig. 1-Fig. 3, can regulate the lock nut of retaining power, comprise the polygonal body 1 of establishing thread circle hole 5, the upper end of described body 1 is provided with a cylindrical shell 2, cylindrical shell 2 adopts the thread circle hole 5 consistent with body, on the sidewall of described body 1, be provided with three pits 101 and on corresponding threaded circular hole wall, be provided with three flanges 102, on the sidewall of described cylindrical shell 2, be provided with and be positioned at sustained height but two elasticity colulus 3 that radially stretch into circular hole 5 of opposite direction, the amplitude that elasticity colulus 3 stretches into is 0.01-2.0mm, the top of crossing described elasticity colulus 3 on the sidewall of described cylindrical shell 2 had the in-line otch 4 of cylindrical shell 2 radiuses.
See Fig. 4, the present embodiment and embodiment's 1 difference are by annular slot 6, to be provided with movable saddle shaped washer 7 in the lower end of described body 1.
When the utility model nut is screwed into bolt, the elasticity colulus 3 in body 1 upper end cylindrical shell 2 can produce the surface friction drag of bolt being detained more to screw thread, and this resistance can, according to the locking power of elasticity colulus 3 radial compression amplitude adjusted retaining, be set prefastening torque power.Utilize in-line otch 4 to exert pressure from end to make cylindrical shell 2 to produce axial crushing deformations simultaneously, make nut to bolt tooth apart from clamping, produce pretightening force.When nut is screwed into bolt clip clamping of workpieces, the saddle shaped washer 7 of body 1 lower end will produce common spring pad effect, and auxiliary nut keeps the steady pressure to workpiece.
