Abstract
A kind of moment of torsion enhancement mode rotational moulding oil tank joint mouth structure, described interface structure is constituted by setting metal inserted piece (2) on oil tank wall (1), it is characterized in that: the wall protruding from oil tank wall (1) towards the end outside fuel tank of described metal inserted piece (2), the part of this protrusion is as the holding division (21) for instrument clip.When fuel tank is carried out extension tube attached assembling, tool card first can be used to clamp holding division to fix metal inserted piece, carry out being screwed into of extension tube attached the most again, be prevented effectively from owing to moment of torsion is excessive and cause and occur between metal inserted piece and oil tank body to loosen with this.
Description
Technical field
This utility model relates to rotational moulding fuel tank, is specifically related to a kind of moment of torsion enhancement mode rotational moulding oil tank joint mouth structure.Described rotational moulding fuel tank can be fuel tank, it is also possible to be the hydraulic oil container for depositing hydraulic oil in hydraulic system.
Background technology
In prior art, the interface that rotational moulding fuel tank externally connects is all to realize by the method for built-in metal mold insert, metal inserted piece is embedded in oil tank wall by whole, metal inserted piece end flushes with oil tank body surface, when docking port (such as oil-out) carries out extension tube attached assembling, it is that extension tube attached is directly threaded into interface (i.e. built-in metal mold insert), restriction due to working of plastics oil tank body Yu metal embedded part bond strength, can cause when moment of torsion is excessive and occur between pre-buried mold insert and oil tank body to loosen, thus cause leakage of oil herein.
Summary of the invention
This utility model purpose is to provide a kind of moment of torsion enhancement mode rotational moulding oil tank joint mouth structure, the problem solving easily to occur metal embedded part to loosen leakage of oil during the interface external pipeline of prior art existence.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of moment of torsion enhancement mode rotational moulding oil tank joint mouth structure, described interface structure is constituted by setting metal inserted piece on oil tank wall, the wall protruding from oil tank wall towards the end outside fuel tank of described metal inserted piece, the part of this protrusion is as the holding division for instrument clip.
In such scheme, the cross sectional shape of described holding division is hexagon.
In such scheme, the cross sectional shape of described holding division is Long Circle.
In such scheme, the cross sectional shape of described holding division can be that rectangle, polygon or circle etc. are variously-shaped, when for, time circular, its outer circumference surface being preferably provided salient point or convex tendon to increase contact friction force.
This utility model compared with prior art, has the advantage that
Owing to this utility model adds a holding division protruding from oil tank wall wall on metal inserted piece, when fuel tank being carried out extension tube attached assembling, tool card first can be used to clamp holding division to fix metal inserted piece, carry out being screwed into of extension tube attached the most again, with this be prevented effectively from due to moment of torsion excessive and cause between metal inserted piece and oil tank body occur loosen.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram.
In the figures above: 1, oil tank wall；2, metal inserted piece；21, holding division.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:
Embodiment: shown in Figure 1:
A kind of moment of torsion enhancement mode rotational moulding oil tank joint mouth structure, described interface structure is constituted by setting metal inserted piece 2 on oil tank wall 1, and the wall protruding from oil tank wall 1 towards the end outside fuel tank of described metal inserted piece 2, the part of this protrusion is as the holding division 21 for instrument clip.
The cross sectional shape of described holding division 21 can be that Long Circle, rectangle, polygon or circle etc. are variously-shaped, when for, time circular, its outer circumference surface being preferably provided salient point or convex tendon to increase contact friction force.
When fuel tank being carried out extension tube attached assembling, tool card need to be used to clamp holding division 21 to fix metal inserted piece, carry out being screwed into of extension tube attached the most again, be prevented effectively from owing to moment of torsion is excessive and cause and occur between metal inserted piece 2 and oil tank body to loosen with this.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
