Background technique
Currently, general bolt can fasten some on-deformable objects, but for those be easy to produce vibration or
Person is influenced the object being easily deformed by external condition, and the fastening effect of general bolt is unsatisfactory, and in addition spring has
The function of deforming and change with object, therefore spring can be used under many operating conditions, but spring how in conjunction with object but always
It is a problem.
In order to guarantee fastening effect, it will appear some technologies for preventing bolt counter-rotating in the market, but these technologies
Be only used for fastening those objects being not easy to deform, once object is influenced by external condition and deformation occurs, this fastening effect
Fruit is with regard to very poor.
In order to overcome the defect of fastening effect difference, some staff can twist bolt with strength, even more so that bolt invader
Body, but this will lead to object deformation, destroy the integrality of object, inherently a kind of defect.
Utility model content
The purpose of this utility model is precisely in order to solve above-mentioned technical problem, and propose a kind of helical spring.Which overcome existing
The deficiency of fastening bolt, be to provide it is a kind of can securing objects and the fastening tool that deforms object, while being not easy again
It loosens.
The utility model provides a kind of helical spring, including nut, bolt and the spring for being welded on bolt bottom end, the spiral shell
Bolt includes upper thread segment, non-threaded section and lower thread segment, and nut is screwed on the upper thread segment, and the spring is arranged in lower screw thread
Section lower section, on coaxial line, the spring bottom end carries out grinding process for the central axis of the spring and the central axis of bolt
Form plane.
As preferred means, the nut is wing nut or six face nuts.
As further preferred means, the height of six face nut and upper thread segment equal length.
As further preferred means, the non-threaded section of upper semisection is equipped with six face bolt heads, and lower semisection is smooth section.
As further preferred means, the hand of spiral of the spring from bottom to top is clockwise.
As further preferred means, the spring diameter is less than the diameter of the lower thread segment unthreaded sections of bolt.
As further preferred means, the bolt bottom end is equipped with ring groove, and the spring upper end is just caught in circle
Ring groove.
A kind of fastening method of helical spring, specific fastening steps are as follows:
1) helical spring size selection: operator confirms the size of wanted fastening bolt holes inner bolt；
2) replacement of bolt: the helical spring that bolt currently in use back-out changes same size screw thread into is fastened；
3) fastening of helical spring: helical spring is inserted into screw hole, in wing nut precession in thread segment, is then carried out clockwise
Wing nut is replaced by helical spring rotation after reaching desired tightness with six face nuts, completes to fasten.
The utility model the utility model has the advantages that using bolt and high-strength spring combination, both can satisfy different degrees of tight
It Gu requiring, and can protect the object fastened, be easily deformed especially suitable for fastening by change of external conditions or itself holds
The object easily shaken.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
A kind of helical spring of the utility model, including nut, bolt 2 and the spring 3 for being welded on 2 bottom end of bolt, the spiral shell
Bolt 2 includes upper thread segment 21, non-threaded section 22 and lower thread segment 23, is screwed with nut on the upper thread segment 21, the spring 3 is set
It sets below lower thread segment 23, the central axis of the spring 3 and the central axis of bolt 2 are on coaxial line, 3 bottom of spring
End carries out grinding process and forms plane.
The nut is wing nut 1 or six face nuts.
The height of six face nut and upper 21 equal length of thread segment.When by helical spring pass through 1 precession screw hole of wing nut
After interior, 1 opposite direction spiral of wing nut is gone out into upper thread segment 21, then by six face nut precessions in thread segment 21, due to six
Nut rotation in face facilitates spiral bolt, but it is larger, and after installing helical spring, the wing nut 1 on securing objects surface can interfere it
He operates, and after the replacement of six face nuts, six face nuts are just bonded with non-threaded section of 22 upper semisection, six face bolt head 221, quite
In in bolt head one six face bolt head of formation.
Non-threaded section of 22 upper semisections are equipped with six face bolt heads 221, and lower semisection is smooth section 222.
The hand of spiral of the spring 3 from bottom to top is clockwise.When spring 3 and bolt hole bottom end contact, spring bottom end
End can generate friction with bottom end, when rotating clockwise helical spring, the end of 3 bottom end of spring can be sliding along bolt hole bottom end
Dynamic, frictional force is small, after fastening helical spring, if helical spring is easy to produce vibration in object itself or temperature is easily varied, is moved through
The end that 3 bottom end of counteracting spring is generated in journey can generate conflict with bolt hole bottom end, and frictional force is larger, and helical spring is not easy to screw out bolt
Hole.Reverse resistance is generated, bolt looseness is prevented.
3 diameter of spring is less than the diameter of 23 unthreaded sections 201 of lower thread segment of bolt 2.3 diameter of spring is small will not
Friction is generated with bolt hole inner wall.
2 bottom end of bolt is equipped with ring groove 202, and 3 upper end of spring is just caught in ring groove 202.Spring 2
Ring groove 202 is sticked into, spring 3 is just more firm when installing with bolt 2, then welds.
Helical spring has different sizes according to actual needs, and spring also requires also to have according to bolt hole depth and to elastic force
There is different intensity, can satisfy the fastening requirements different to object.
A kind of fastening method of helical spring, specific fastening steps are as follows:
1) helical spring size selection: operator confirms the size of wanted fastening bolt holes inner bolt；
2) replacement of bolt: the helical spring that bolt currently in use back-out changes same size screw thread into is fastened；
3) fastening of helical spring: helical spring is inserted into screw hole, in 1 precession of wing nut in thread segment 21, then clockwise
Helical spring rotation is carried out, after reaching desired tightness, wing nut 1 is replaced with six face nuts, completes to fasten.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
