Description
Technical field
The utility model belongs to the technology of gasoline engine field, specifically, and the particularly base of fuel tank underneath type petrol engine.
Background technique
At present, the miniature gasoline engines such as 139F generally adopt fuel tank underneath type structure, that is: fuel tank is positioned at the lowermost end of machine, are supported the weight of whole machine by fuel tank.Because fuel tank is working of plastics, the intensity of itself is limited, and not wear-resisting, and fuel tank directly contacts with ground, is subjected to the impact of complete machine operation vibration in long-term the use, and fuel tank deforms easily or weares and teares, and the working life of fuel tank is shorter.In case the fuel tank damage can cause fuel leakage, not only waste fuel oil, befouling environment, and have the potential safety hazards such as inflammable and explosive.Simultaneously, support the weight of whole machine by fuel tank, stability is also relatively poor.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of petrol engine oil tank base that can prevent effectively that fuel tank from damaging.
The technical solution of the utility model is as follows: a kind of understructure, has pedestal (1), described pedestal (1) is flat " U " shape, by base plate (1a), front side plate (1b) and back side panel (1c) form, two ends, the left and right sides at described front side plate (1b) top are symmetrically arranged with journal stirrup (1d), this journal stirrup (1d) is upper to offer via hole along fore-and-aft direction, the front end of the bottom of described front side plate (1b) and base plate (1a) is fixedly linked, the bottom of the rear end of base plate (1a) and back side panel (1c) is fixedly linked, two ends, the left and right sides at described back side panel (1c) top are symmetrically arranged with boss (1e), this boss (1e) is rearward outstanding, and offers along the vertical direction pilot hole on the boss (1e).
The utility model is installed at the bottom of fuel tank, pedestal is flat " U " shape, this pedestal catches fuel tank, two positioning blocks and two positioning tables on the petrol engine pulling plate of two journal stirrups on the pedestal front side plate and fuel tank front are corresponding, the screw that wears from front to back passes via hole, the mounting hole on the pulling plate positioning table and the pilot hole on the fuel tank positioning block on the front side plate journal stirrup, and front side plate journal stirrup, pulling plate positioning table and fuel tank positioning block are fixed together.Two platforms and two locating columns on the crankcase of two boss on the pedestal back side panel and fuel tank back are corresponding, the screw that wears from the bottom up passes the pilot hole on the back side panel boss, the via hole on the fuel tank platform successively, and extend in the mounting hole of crankcase locating column, back side panel boss, fuel tank platform and crankcase locating column are fixed together.
This shows that the utility model does not change the original structure of petrol engine, and ingeniously utilize the mounting structure between fuel tank and pulling plate and the crankcase to assemble, not only assembling is simple, convenient, and the soundness that connects is good, can not occur loosening or comes off.The utility model catches fuel tank from the bottom up, the weight of whole machine is supported by the utility model, avoided fuel tank directly to contact with ground, can prevent effectively that fuel tank from deforming or wear and tear, fuel tank can not be subjected to the impact of complete machine operation vibration and be damaged, both improve the Security that fuel tank uses, greatly prolonged again the working life of fuel tank.The utility model is flat-bottom structure, and the area of contact with ground is large like this, supports the good stability of whole machine.
Between two boss (1e), be provided with riser (1f), this riser (1f) is extended and is formed by the middle part of back side panel (1c) one that makes progress, have the gap between described riser (1f) and the boss (1e), and the end face of riser (1f) is higher than the end face of described boss (1e).Above structure can strengthen the structural strength of back side panel on the one hand, and on the other hand, riser is positioned at the below at the circular convex closure of crankcase place, plays supplemental support, supports the stability of whole machine with further raising.
The end face of described riser (1f) is concave arc shape.The circular convex closure of the shape of riser end face and crankcase adapts, and the so not only better effects if of supplemental support, and riser is combined closely with the circular convex closure of crankcase, has more in appearance aesthetic feeling.
The angle that has 110-120 ° between described front side plate (1b) and the base plate (1a), described journal stirrup (1d) vertically arranges.Above structure can either guarantee that base structure is small and exquisite, can avoid again the counterpart of front side plate and fuel tank to interfere; Simultaneously, the counterpart of the adjacent fuel tank of front side plate makes the combination of pedestal and fuel tank compacter.
In order to make things convenient for manufacturing, reduce production costs, described base plate (1a), front side plate (1b), back side panel (1c), journal stirrup (1d) and boss (1e) are by the injection moulding global formation.
In order to increase structural strength, prevent that pedestal from deforming or wear and tear, and is distributed with stiffening rib at described base plate (1a), front side plate (1b) and back side panel (1c).
Beneficial effect: the utility model supports the weight of whole petrol engine, the good stability that not only supports, and can effectively prevent fuel tank distortion or wearing and tearing, Effective Raise working life and the Security of fuel tank; The utility model does not change the original structure of petrol engine, and utilizes that existing mounting structure assembles on the petrol engine, and dismounting is not only convenient but also quick.
