Abstract
The utility model discloses a kind of Shock-proof bolt of preset anti-dropout, it includes bolt, the swivel nut being set on the bolt, the upper damping washer for being set in the swivel nut top and the lower damping washer that the swivel nut lower part is set, the swivel nut includes the swivel nut ontology of tubulose, from the upper end of the swivel nut ontology, vertically the swivel nut ontology extends outwardly gasket part annular in shape, and the protrusion of the lower end outwardly convex from the swivel nut ontology, the inner ring of the lower damping washer matches setting with the outer surface of the body part, since the utility model is separated swivel nut with engine bonnet by upper damping washer and lower damping washer, avoid the direct contact of the two, the noise that collision generates both to reduce；The lower part of swivel nut is blocked with damping washer at present, so that not easy to fall off when swivel nut is preset.
Description
Technical field
The utility model relates to the Shock-proof bolts and engine bonnet of a kind of preset anti-dropout.
Background technique
Since to the technical requirements for mitigating engine weight, current engine bonnet is usually alloy or high temperature resistant modeling
Material is made, but also the plasticity of engine bonnet largely increases, it is integrated to can adapt to complicated mechanism.
But the technical problem that the engine bonnet being molded at present is big there are noise, due to the engine bonnet weight of plastics
Smaller, when encountering engine operation, the vibration of engine is transmitted to engine bonnet, engine bonnet and engine body it
Between collision generate noise, collision between engine bonnet and fixing bolt generates noise.Existing shock-dampening method is to pass through
Sealing strip progress damping between engine bonnet and engine body, but making an uproar between engine bonnet and fixing bolt
Sound still has.
Therefore, a kind of Shock-proof bolt of preset anti-dropout that can largely reduce noise is needed at present.
Summary of the invention
The purpose of the utility model is to provide the Shock-proof bolts that one kind can largely reduce the preset anti-dropout of noise.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of Shock-proof bolt of preset anti-dropout comprising bolt, the swivel nut being set on the bolt, be set in it is described
The upper damping washer on swivel nut top and the lower damping washer that the swivel nut lower part is arranged in, the swivel nut includes the swivel nut sheet of tubulose
Body, from the upper end of the swivel nut ontology, vertically the swivel nut ontology extends outwardly gasket part annular in shape, and from the swivel nut
The protrusion of the lower end outwardly convex of ontology, the inner ring of the lower damping washer is matched with the outer surface of the body part to be set
It sets.
Preferably, the bolt includes bolt body, the bolt cap that the bolt body upper end is arranged in, and setting exists
The bolt body lower part and the threaded portion of the protrusion bolt body.
It is further preferred that the inner wall protrusion of the swivel nut ontology is provided at least one protrusion.
Preferably, distance of the threaded portion apart from the bolt cap is less than or equal to the length of the swivel nut.
Preferably, the upper damping washer includes circular the first damping portion being arranged in below the gasket part, and
The second damping portion of circular tube shaped is extended downwardly into from the inner ring of first damping portion.
It is further preferred that the upper and lower surfaces of first damping portion are provided with the bulge loop of annular.
A kind of engine bonnet uses the Shock-proof bolt of above-mentioned preset anti-dropout.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
Since the utility model is separated swivel nut with engine bonnet by upper damping washer and lower damping washer, avoid
The direct contact of the two, to reduce the noise that the two collision generates；The lower part of swivel nut is blocked with damping washer at present, so that
It is not easy to fall off when swivel nut is preset.

Specific embodiment
Embodiment shown in reference to the accompanying drawing is further described the utility model:
Referring to shown in attached drawing 1-2, the fixation hole of engine bonnet 1 is arranged in a kind of Shock-proof bolt 2 of preset anti-dropout
In comprising it bolt 2, the swivel nut 3 being set on the bolt 2, the upper damping washer 4 for being set in 3 top of swivel nut and sets
Set the lower damping washer 5 in 3 lower part of swivel nut, the swivel nut 3 includes the swivel nut ontology 31 of tubulose, from the swivel nut ontology 31
The upper end gasket part 32 that vertically the swivel nut ontology 31 extends outwardly annular in shape, and from the lower end of the swivel nut ontology 31
The inner ring of the protrusion 33 of outwardly convex 34, the lower damping washer 5 matches setting with the outer surface of the swivel nut ontology 31.
Referring to figure 1, lower damping washer 5 is passed through protrusion 33 after engine bonnet 1 and is set in swivel nut by swivel nut 3
3 lower part, so that swivel nut 3 is preset at engine bonnet 1 and will not fall off
The bolt 2 includes bolt body 21, the bolt cap 22 that 21 upper end of bolt body is arranged in, and setting exists
21 lower part of bolt body and the threaded portion 23 of the protrusion bolt body 21.The inner wall of the swivel nut ontology 31 protrudes setting
There is at least one protrusion 34.Distance of the threaded portion 23 apart from the bolt cap 22 is less than or equal to the length of the swivel nut 3.?
When bolt 2 and swivel nut 3 assemble, bolt 2 is put into swivel nut 3, and stamps out protrusion 34 on swivel nut ontology 31, protrusion 34 can
The threaded portion 23 on bolt 2 is blocked, is skidded off so that bolt 2 can not fill in swivel nut 3.
The upper damping washer 4 includes the first damping portion 41 that annular shape is arranged in below the gasket part 32, and from
The inner ring of first damping portion 41 extends downwardly into the second damping portion 42 of circular tube shaped.First damping portion 41 by gasket part 32 with
It is separated between engine bonnet 1；Second damping portion 42 is set on swivel nut 3 so that swivel nut ontology 31 and engine bonnet 1 it
Between separate contacted so that bolt 2, swivel nut 3 be not direct with engine bonnet 1, so as to avoid the collision between them
The sound of generation.
The upper and lower surfaces of first damping portion 41 are provided with the bulge loop 6 of annular.The section of bulge loop 6 is semicircle
Shape, after being under pressure, the bulge loop 6 of upper and lower surface deforms respectively and is tightly attached to swivel nut 3 and engine bonnet 1 can play compared with
Good sealing effect.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
