Abstract
The utility model provides a little screw hole, it has the stay bolt to form a complete set on the little screw hole, and the stay bolt supports in grooved surface that stop nut has a recess in the stop nut middle section, has a plurality of evenly distributed size to equal around the screw hole. During the use, screw up the stay bolt around the screw hole downwards, played further fixing bolt stop nut's effect under the effect of power, prevent more easily than conventional method that the nut from droing from the bolt.
Description
Technical field
The utility model relates to a kind of nut, is specifically related to a kind of lock nut.
Background technique
Nut is exactly nut, is used for the part played the role of fastening with bolt or screw rod together with being screwed in, all manufacturing machinery must a kind of element.Wherein lock nut is the wherein one in nut, and it is by certain vibrational power flow, can prevent this lock nut from dropping from bolt absent-mindedness.
At present, life and the lock nut of industrial mounting article, what general two nuts limited mutually is used for preventing lock nut from dropping from bolt absent-mindedness, but still the phenomenon that existence causes lock nut to come off from bolt due to the vibration of environmental factor.
Model utility content
The purpose of this utility model is to provide a kind of lock nut, lock nut is provided with groove, bolt hole is screwed into a circle stove bolt, stove bolt supports into groove surface, serve the effect of further fix bolt-unfastening preventing nut under force, comparatively conventional method more easily prevents nut from coming off from bolt.
Lock nut described in the utility model, described lock nut axially offers the tapped hole running through this lock nut, described lock nut stage casing offers a groove from tapped hole to lock nut outer wall direction, and the degree of depth of described groove is the half of this lock nut sidewall thickness; Described lock nut is uniformly distributed and equal minor thread hole, aperture offering at least 4 around tapped hole place, and lock nut end face is run through to groove in described minor thread hole, and supporting on minor thread hole have stay bolt, and stay bolt is butted on groove groove face.
As preferred version of the present utility model, described groove is provided with anticracking arc near the top of lock nut sidewall.
As preferred version of the present utility model, the position of described groove is at 2/3rds places of lock nut height.
As preferred version of the present utility model, described minor thread hole is positioned at 2/3rds sides of groove and lock nut end face.
As preferred version of the present utility model, the head of described stay bolt has a small through hole.
As preferred version of the present utility model, the small through hole iron wire of described stay bolt head is connected.
As preferred version of the present utility model, described lock nut is uniformly distributed and equal minor thread hole, aperture offering 6 around tapped hole place.
Owing to adopting technique scheme, the utility model tool has the following advantages:
Lock nut of the present utility model, by rational vibrational power flow, make this lock nut in use, the stay bolt around downward threaded together hole, serve the effect of further fix bolt-unfastening preventing nut under force, comparatively conventional method more easily prevents nut from coming off from bolt.

Fig. 2: the plan view of lock nut.
Fig. 3: front view when lock nut uses.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1-3, lock nut provided by the utility model, described lock nut axially offers the tapped hole 1 running through this lock nut, lock nut stage casing preferably lock nut height 2/3rds place digs a groove 2 from tapped hole 1 to lock nut outer wall direction, groove 2 degree of depth is the half of lock nut sidewall thickness, groove 2 is anticracking arc shape 5 near the top of lock nut sidewall, around tapped hole 1, there are at least 4 to be uniformly distributed equal-sized minor thread hole 3, also can distribute 6 to 8 minor thread holes 3, minor thread hole 3 degree of depth is the length of distance groove 2 side far away to groove 2, supporting on minor thread hole 3 have stay bolt 4.
The utility model in use, king-bolt 7 is screwed into after in tapped hole 1, is screwed in minor thread hole 3, is screwed to all stay bolts 4 always and is butted on groove 2 groove face, twist stay bolt 4 downwards further, will produce downward power to groove 2, make slot opening dilatating and deformable respectively, the opening of distortion acts on the screw thread of king-bolt, produce power up and down, thread pitch on the screw thread of tapped hole 1 and king-bolt 7 is misplaced, increases the friction factor between two screw threads, be fitted together to more closely.In order to prevent screw cap-falling further, open a small through hole 6 at each top being screwed into the stay bolt 4 in minor thread hole, all small through hole 6 use iron wire class object to be together in series, and tighten up rear knotting and fix, several stay bolt 4 is checked and balance, prevents stay bolt 4 from rotating pine and move back.
Lock nut of the present utility model, by being provided with groove on lock nut, bolt hole is screwed into a circle stove bolt, and stove bolt supports into groove, serve the effect of further fix bolt-unfastening preventing nut under force, comparatively conventional method more easily prevents nut from coming off from bolt.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
