Abstract
A kind of fastening U-bolt component, including U-bolt ontology and flange surface nut, acting surface on U-bolt body bottom portion is plane, and the threaded portion on U-bolt ontology both ends is different rotation direction screw threads, and two flange surface nuts are engaged with respective matched threaded portion respectively；Different rotation direction screw threads on U-bolt ontology both ends, and using the flange surface nut that can increase contact surface, it can prevent nut from being influenced generation inertia jerk by road surface factor and loosened；Acting surface on U-bolt ontology is plane, and vehicle frame is because being there is adverse consequences by concentrfated load when can prevent from tightening.
Description
Technical field
The utility model relates to fastener areas more particularly to a kind of fastening U-bolt components.
Background technique
U-bolt component is to realize the common components that are fastenedly connected with chassis of dress part in commercial vehicle, U-bolt component by
U-bolt and nut composition.
As illustrated in fig. 1 and 2, common U-bolt uses round steel cold drawn forming, and U-bolt is by a bottom 1 and two d-axis portions
2 form, and the composition of threaded portion 3 is equipped on the end in two d-axis portions.Because the bottom cross section of U-bolt is circle, when assembly, is U-shaped
Acting surface 101 on stud base is linearly contacted with chassis frame lower aerofoil, easily causes vehicle frame aerofoil by concentrfated load, out
The hidden danger such as existing U-bolt deformation leads to fill part Joint failure, and being broken occurs in vehicle frame stress concentration.On U-bolt both ends
Threaded portion pass through pressing plate 4 and fastened with hex nut 5, dress is partially and the connection on chassis in realization；Because of the threaded portion of U-bolt
It for same rotation direction screw thread, and is matched using the lesser hex-head nut of contact surface, is influenced to will lead to spiral shell by bumpy road factor
Mother loosens.
Summary of the invention
To overcome existing U-bolt component to have the defects that linear contact and nut loosening, the utility model proposes one kind
Fastening U-bolt component.
The technical solution of the utility model are as follows: a kind of fastening U-bolt component, including U-bolt ontology and flange face
Nut, it is characterised in that: the acting surface on U-bolt body bottom portion is plane, and the threaded portion on U-bolt ontology both ends is not
With rotation direction screw thread, two flange surface nuts are engaged with respective matched threaded portion respectively.
Above-mentioned technical proposal is further improved, the side of the U-bolt body bottom portion, which is equipped with, tightens up prompt word
Sample.Increase tightens up prompt printed words, operator can be reminded periodically to tighten nut, avoids because of unnecessary loss caused by loosening.
The utility model has the advantages that
In the utility model, different rotation direction screw threads on U-bolt ontology both ends, and using the flange that can increase contact surface
Face nut can prevent nut from being influenced generation inertia jerk by road surface factor and loosened；Acting surface on U-bolt ontology
For plane, vehicle frame is because being there is adverse consequences by concentrfated load when can prevent from tightening.
Detailed description of the invention
Fig. 1 is U-bolt component structure diagram in the prior art.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural schematic diagram of the utility model.
Fig. 4 is the left view of Fig. 3.
Specific embodiment
Single to reduce nut fastening means, the drawbacks of linearly contact on existing U-bolt there are acting surface, this is practical
In novel, U-bolt ontology, which locally uses to forge into plane and increase, tightens up prompt, processes different rotation direction screw threads at both ends and adopts
With flange surface nut, original structure drawback can be effectively overcome, realize reinforcement effect.
As shown in Figure 3 and Figure 4, a kind of fastening U-bolt component, including it is U-bolt ontology 6, left-handed to flange face spiral shell
To flange surface nut 8, the acting surface on U-bolt body bottom portion is plane 601 for mother 7 and dextrorotation, i.e., the cross section of bottom is in square
Shape, the threaded portion on U-bolt ontology both ends are different rotation direction screw threads, i.e. threaded portion on U-bolt ontology left end is left-handed
Threaded portion on screw thread 9, right end is dextrorotation to screw thread 10, and two flange surface nuts are nibbled with respective matched threaded portion respectively
Close, i.e., it is left-handed to flange surface nut with it is left-handed engaged to screw thread, dextrorotation is engaged with dextrorotation to screw thread to flange surface nut；
The side of the U-bolt body bottom portion, which is equipped with, tightens up prompt printed words 11, such as: " periodically tightening up " tightens up prompt
Printed words.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.Do not elaborate place in this specification, is technology well known in the art.
