Belong to technical field of automobile parts.
Background technique
Automotive fuel oil system is for the system and device according to operating condition to engine oil on automobile, wherein being located at vehicle body
On fuel tank and engine between using fuel pipe connect, vehicle fuel pipe be mainly used for provide gasoline flow pipe, with
The raising of fuel evaporation emission regulation demands, permeability and intensity to fuel pipe are also promoted therewith.
Fuel pipe generally includes fuel pipe and connector.Fuel pipe is used to transmit fuel oil, the freedom of fuel pipe to engine
End has corresponding flaring, and fuel pipe is connect with quick coupling type of attachment with nylon tube by flaring and rubber tube connection enlarging
Form is connect with rubber tube, realizes the connection of fuel tank and motor mechanisms, to transmit fuel oil to mechanisms such as engines.
Fuel pipe used at present, body portion diameter is relatively small, and high, the preferable nylon material of toughness using intensity
Material is made, and structure is complicated for junction portion, is relatively large in diameter, and material is harder, and resistance to compression and impact resistant capability are relatively weak, by
To damage is be easy to cause when impact, so as to cause fuel oil leakage, more seriously then cause fire.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of crash-proof novel fuel for the above-mentioned prior art
Pipe joint structure, while simplifying joint structure, it is ensured that its resistance to compression, impact resistant capability.
A kind of the technical scheme in the invention for solving the above technical problem are as follows: crash-proof novel fuel pipe fitting knot
Structure, it includes joint body, and the joint body includes successively preceding latter linked connector leading portion, connector middle section and connector back segment,
The connector middle section is made of multiple step surfaces, and the connector leading portion is circular configuration, is connected with automobile component, the connector
The end of back segment is equipped with the flaring with piping connection, is arranged with the metal to shield on the periphery of the connector leading portion
Ring.
Preferably, the whole wall thickness of the joint body thickens 2.5-3.5mm by original 1.5-2mm.
Preferably, a pair of grip part outwardly protruded is equipped on the periphery of the connector leading portion, which is used for
The connecting hole of squeezed joint leading portion, convenient for the assembly or disassembly of connector, the grip part rotates 45° angle, before causing a deviation from connector
The horizontally or vertically line of section disc, the position matched on the becket with the grip part on connector leading portion open up through-hole,
So that grip part is exposed.
Preferably, the wall thickness is 0.5-1.5mm.
Compared with the prior art, the advantages of the utility model are:
The utility model improves complicated connector leading portion, in order to can smoothly be arranged the metal to shield
Ring, while the wall thickness of butt joint entirety is enhanced, and prevents from damaging in knockout process；Furthermore by the gripping on former connector
Portion rotates 45° angle, causes a deviation from horizontal line or vertical line position, far from easy rum point, to improve the use longevity of entire connector
Life.
Detailed description of the invention
Fig. 1 is the structural blast schematic diagram in the utility model embodiment.
Fig. 2 is the structure assembling schematic diagram in the utility model embodiment.
Fig. 3 is the structure sectional view in the utility model embodiment.
Wherein:
Joint body 1
Connector leading portion 1.1
Grip part 1.1.1
Connector middle section 1.2
Connector back segment 1.3
It is flared 1.3.1
Becket 2
Through-hole 2.1.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Such as Fig. 1, shown in 2,3, one of the present embodiment crash-proof novel fuel pipe joint structure, including joint body 1,
The whole wall thickness of joint body 1 thickens 2.5-3.5mm by original 1.5-2mm, to improve the entire compression and crashworthiness of connector
Ability is hit, the joint body 1 divides for 1.3 3 connector leading portion 1.1, connector middle section 1.2 and connector back segment parts, the connector
Middle section 1.2 is made of multiple step surfaces, so that slowly become smaller by the diameter of connector leading portion 1.1 to connector back segment 1.3, the connector
Leading portion 1.1 is circular configuration, is connected with components such as the engines of automobile, belongs to diameter the best part on joint body 1,
The periphery of the connector leading portion 1.1 is equipped with a pair of grip part 1.1.1 outwardly protruded, and grip part 1.1.1 is for squeezing
The connecting hole of connector leading portion 1.1, convenient for the assembly or disassembly of connector, previous grip part 1.1.1 is mounted on the water of connector leading portion 1.1
On flat or vertical line, i.e., the position most easily contacted with external shock, in order to avoid these rum points, by the grip part
1.1.1 45° angle is rotated, the horizontally or vertically line of 1.1 disc of connector leading portion is caused a deviation from, in the end of the connector back segment 1.3
Equipped with the flaring 1.3.1 with piping connection.
Since connector leading portion 1.1 is the position of the most easy damaged in collision of entire pipeline structure, also not only by thickened wall
It can complete to improve intensity, therefore be equipped with becket 2 in 1.1 outer sheath of connector leading portion of the joint body 1, in the becket 2
It is upper to open up through-hole 2.1 with the position matched the grip part 1.1.1 on connector leading portion 1.1, so that grip part 1.1.1 is exposed,
Convenient for pressing.The wall thickness of becket is 0.5-1.5mm.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
