The utility model discloses a kind of nuts, components for solid mechanical equipment, it includes ontology, ontology includes shell and through-hole, thread segment and unthreaded hole section are provided in through-hole, thread segment and unthreaded hole section are arranged on the inner wall of shell, and unthreaded hole section is located at below thread segment, have the advantages that rotation of the screw rod in nut becomes more flexible.
Description
Technical field
The utility model relates to mechanical fastening system technical field, in particular to a kind of nut.
Background technique
Last procedure that link is horizontal casting production technology is broken, it is by backpressure device, support device and breaks
Device three parts composition, backpressure device need to carry out manual adjustment according to the specification of actual production profile.Backpressure device includes back-pressure
Roller when needing to adjust anti-roll position height, twists back-pressure adjusting screw rod.
Since the height of nut must be over the thickness of crossbeam to be fixed, nut-welding is on crossbeam, so, back-pressure
The length of the threaded engagement part of adjusting screw rod and nut just seems longer, and artificial external force turns screw rod, the threaded engagement of nut
Length is longer, and resistance is bigger, and it is harder manually to turn back-pressure screw rod, is influenced by machining accuracy and actual use operating condition, it may appear that
The phenomenon that artificial external force of back-pressure screw rod can not be adjusted.
Utility model content
The purpose of the utility model is to provide a kind of nuts, and which solve the longer resistance of the length of thread engagement of nut is bigger
The problem of, have the advantages that rotation of the screw rod in nut becomes more flexible.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of nut, including ontology, ontology include shell and through-hole, and thread segment and unthreaded hole section, screw thread are provided in through-hole
Section and unthreaded hole section are arranged on the inner wall of shell, and unthreaded hole section is located at below thread segment.
By adopting the above technical scheme, in use, screw rod is screwed into nut nut by operator, the spiral shell in nut
Line section and screw rod engagement rotation shorten the length of thread segment, reduce screw thread by the way that thread segment and unthreaded hole section are arranged in through-hole
Section and screw rod engagement rotation bring frictional resistance, so that nut rotation is more flexible, operator's rotating nut more saves labour,
Reduce the labor intensity of operator.
Further preferably are as follows: cover top portion is provided with the abutting component for pushing against screw rod, and abutting component includes that abutting is thin
Piece and spring, spring one end are welded on cover top portion, and the spring other end is welded on shell top with thin slice welding, abutting thin slice is abutted
Portion.
By adopting the above technical scheme, in use, since nut-welding is on crossbeam to be fixed, nut cannot turn
Dynamic, by rotating screw rod, screw rod cooperates with nut fixes crossbeam to be fixed, when screw tip is bonded with nut top,
Screw tip squeeze abut thin slice, abut thin slice deformation occurs squeeze spring, spring contraction, due to spring elastic force have restore
Trend will abut thin slice and screw tip and push against, prevent screw rod from loosening in nut.
Further preferably are as follows: it is hemispherical to abut thin slice setting.
By adopting the above technical scheme, when screw rod is turned to flap contact is abutted, screw tip touches hemisphere first
The top of shape will not scrape the side for abutting thin slice, will not damage abutting thin slice, at the same hemispherical can disperse to abut thin slice by
Extruding force from screw rod prevents from abutting thin slice damage, extends the service life for abutting thin slice.
Further preferably are as follows: abut component and multiple groups are set, multiple groups abutting component is uniform, is distributed in cover top portion.
By adopting the above technical scheme, increase the contact area for abutting component and screw tip, so that screw tip and nut
What is be bonded is even closer, enhances the fastening effect of nut.
In conclusion the utility model has the following beneficial effects:
1. in use, operator twists screw rod to nut by being provided with thread segment and unthreaded hole section in through-hole
Into in nut, thread segment and screw rod engagement rotation in nut, thread segment and screw rod engagement rotation, by the way that screw thread is arranged in through-hole
Section and unthreaded hole section, shorten the length of thread segment, thread segment and screw rod engagement rotation bring frictional resistance are reduced, so that spiral shell
Mother's rotation is more flexible, and operator's rotating nut more saves labour, and reduces the labor intensity of operator；
2. being provided with the abutting component for pushing against screw rod by cover top portion, abutting component includes abutting thin slice and bullet
Spring, since nut-welding is on crossbeam to be fixed, nut is not able to rotate, and by rotating screw rod, screw rod will be to nut cooperation
Fixed crossbeam is fixed, and when screw tip is bonded with nut top, screw tip, which squeezes, abuts thin slice, abuts thin slice and shape occurs
Become and squeeze spring, spring contraction, the trend restored will abut thin slice and screw tip pushes against since the elastic force of spring has, and prevent
Screw rod loosens in nut；
3. hemispherical by abutting thin slice setting, when screw rod is turned to flap contact is abutted, screw tip is first
Touch hemispheric top, the side for abutting thin slice will not be scraped, will not damage abutting thin slice, at the same hemispherical can disperse to
Thin slice is connect by the extruding force from screw rod, prevents from abutting thin slice damage, extends the service life for abutting thin slice；
4. multiple groups are arranged by abutting component, multiple groups abutting component is uniform, is distributed in cover top portion, increases abutting group
The contact area of part and screw tip enhances the fastening effect of nut so that screw tip is bonded even closer with nut.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of nut, the components for solid mechanical equipment.
As depicted in figs. 1 and 2, it includes shell 11 and through-hole 12, offers thread segment 13 and unthreaded hole on 12 inner wall of through-hole
Section 14, unthreaded hole section 14 are arranged below threaded hole.
Three groups of abutting components 2 are welded at the top of shell 11, three groups of abutting components 2 are uniform, are distributed in 11 top of shell,
Abutting component 2 includes abutting thin slice 21 and spring 22, and 22 one end of spring is welded on 11 top of shell, 22 other end of spring with abut
Thin slice 21 welds, and abuts thin slice 21 and is welded on 11 top of shell, it is hemispherical to abut thin slice 21.
Working principle: screw rod is screwed into nut by operator using spanner, thread segment 13 and screw rod engagement in nut
Rotation shortens the length of thread segment 13, reduces 13 He of thread segment by the way that thread segment 13 and unthreaded hole section 14 are arranged in through-hole 12
Screw rod engagement rotation bring frictional resistance, so that nut rotation is more flexible, operator's rotating nut more saves labour, and reduces
The labor intensity of operator.
When screw rod is screwed to bottom, screw tip extruding screw top squeeze abuts thin slice 21, and abutting thin slice 21, deformation occurs
Spring 22 is squeezed, spring 22 is shunk, and is supported since there is the elastic force of spring 22 trend restored will abut thin slice 21 with screw tip
Tightly, prevent screw rod from loosening in nut.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as within the protection scope of the present utility model all by the protection of Patent Law.
