Abstract
The invention discloses a nut with an anti-loose function and convenient to tighten. The nut comprises a nut body, multiple elastic protrusions are arranged on any one end face of the nut body and can elastically deform in the process of fastening the nut body, and the free end of each elastic protrusion inclines in a direction of loosening the nut. In the structure, the nut body is used for being in threaded connection with a screw to fasten mutual connection. In the structure, under the circumstance that an elastic pad is not used in a matched manner, the nut has high anti-loosen capability; the free end of each elastic protrusion inclines in the direction of loosening the nut, deformation of the elastic protrusions can be guided in the process of tightening the nut, in this way, it is easy to force the elastic protrusions to elastically deform to realize the technical effect of tightening the nut.
Description
Technical field
The present invention relates to mechanical fastener technical field, particularly relate to and a kind ofly there is locking functions and be convenient to the nut tightened.
Background technique
Bolt is a kind of mechanical parts, is generally the cylindrical threaded fastening piece of adapted nut.Bolt is made up of head and screw rod (with externally threaded cylindrical body) two-part, and need and nut screw connection during use, for being fastenedly connected two parts with through hole, this Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.Divide by the force way connected: point common and have articulation hole.Divide by nose shape: have hexagon head, round end, square spigot, countersunk head etc.Wherein hexagon head is the most frequently used.
At present, for bolted locking, comparatively general a kind of form adopts elastic washer.But in the maintenance process or assembly process of reality; particularly in maintenance process, often can, because the carelessness or not responsible of maintainer, elastic washer be sheathed on bolt; cause tie point absent-mindedness under vibrations, occur seal failure or connect lax situation occurring.
Summary of the invention
For in above-mentioned prior art in the maintenance process of reality or assembly process; particularly in maintenance process; frequent meeting is because the carelessness or not responsible of maintainer; elastic washer is not sheathed on bolt; cause tie point absent-mindedness under vibrations; there is seal failure or connect lax situation produced problem, the invention provides and a kind ofly there is locking functions and be convenient to the nut tightened.
Provided by the invention a kind ofly have locking functions and the nut being convenient to tighten solves problem by following technological points: a kind of have locking functions and be convenient to the nut tightened, comprise nut body, any one end face of described nut body is also provided with multiple elastic bumps, can there is elastic strain in described elastic bumps, the free end of described elastic bumps tilts towards the direction of relaxing nut in the process that nut body is fastening.
In this structure, the nut body of setting is used for being connected with screw flight, with fastening interconnective connection.In this structure, by arranging elastic bumps on the end face of any one end of nut body, like this, in the process that nut is tightened, elastic bumps and absorption surface generation elastic strain, the elastic force that above elastic strain produces can be used as the locking prestressing force of nut body, like this, this bolt is not when matching use cushion, also there is good anti-loosening ability, adopt the free end of elastic bumps towards the setting of the direction inclination of absent-mindedness nut, in the process can tightened at nut, leading role is produced to the distortion of elastic bumps, like this, be easy to force elastic bumps resiliently deformable, reach the technique effect being convenient to tightening nuts.
Further technological scheme is:
For making above prestressing force be uniformly distributed in the circumference of nut body, described elastic bumps is uniform in the form of a ring relative to the axis of nut body.
As making above prestressing force be uniformly distributed further technological scheme in the circumference of nut body, the number of described elastic bumps is greater than 3.
As a kind of bolt pattern being convenient to manufacturing, described nut body and elastic bumps are the overall structure by casting.
The present invention has following beneficial effect:
In this structure, the nut body of setting is used for being connected with screw flight, with fastening interconnective connection.In this structure, by arranging elastic bumps on the end face of any one end of nut body, like this, in the process that nut is tightened, elastic bumps and absorption surface generation elastic strain, the elastic force that above elastic strain produces can be used as the locking prestressing force of nut body, like this, this bolt is not when matching use cushion, also there is good anti-loosening ability, adopt the free end of elastic bumps towards the setting of the direction inclination of absent-mindedness nut, in the process can tightened at nut, leading role is produced to the distortion of elastic bumps, like this, be easy to force elastic bumps resiliently deformable, reach the technique effect being convenient to tightening nuts.
Accompanying drawing explanation
Fig. 1 of the present inventionly a kind ofly has locking functions and is convenient to the structural representation of the nut specific embodiment tightened.
Numbering in figure is followed successively by: 1, nut body, and 2, elastic bumps.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples.
Embodiment 1:
As shown in Figure 1, a kind of have locking functions and be convenient to the nut tightened, comprise nut body 1, any one end face of described nut body 1 is also provided with multiple elastic bumps 2, can there is elastic strain in described elastic bumps 2, the free end of described elastic bumps 2 tilts towards the direction of relaxing nut in the process that nut body 1 is fastening.
In this structure, the nut body 1 of setting for being connected with screw flight, with fastening interconnective connection.In this structure, by arranging elastic bumps 2 on the end face of any one end of nut body 1, like this, in the process that nut is tightened, elastic bumps 2 and absorption surface generation elastic strain, the elastic force that above elastic strain produces can be used as the locking prestressing force of nut body 1, like this, this bolt is not when matching use cushion, also there is good anti-loosening ability, adopt the free end of elastic bumps 2 towards the setting of the direction inclination of absent-mindedness nut, in the process can tightened at nut, leading role is produced to the distortion of elastic bumps 2, like this, be easy to force elastic bumps 2 resiliently deformable, reach the technique effect being convenient to tightening nuts.
Embodiment 2:
As shown in Figure 1, the present embodiment is further qualified on the basis of embodiment 1: for making above prestressing force be uniformly distributed in the circumference of nut body 1, described elastic bumps 2 is uniform in the form of a ring relative to the axis of nut body 1.
As making above prestressing force be uniformly distributed further technological scheme in the circumference of nut body 1, the number of described elastic bumps 2 is greater than 3.
As a kind of bolt pattern being convenient to manufacturing, described nut body 1 and elastic bumps 2 are the overall structure by casting.
Above content is the further description done the present invention in conjunction with concrete preferred implementation, can not assert that the specific embodiment of the present invention is confined to these explanations.For general technical staff of the technical field of the invention, not departing from other mode of executions drawn under technological scheme of the present invention, all should be included in protection scope of the present invention.
