Description
Technical field
The invention belongs to technology of gasoline engine field, specifically, 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 subject to the impact of complete machine operation vibration in long-term use, and fuel tank easily deforms or weares and teares, and the working life of fuel tank is shorter.Once fuel tank damage can cause fuel leakage, not only waste fuel oil, befouling environment, and there is the potential safety hazards such as inflammable and explosive.Meanwhile, supported the weight of whole machine by fuel tank, stability is also poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of petrol engine oil tank base that can effectively prevent that fuel tank from damaging.
Technological scheme of the present invention is as follows: a kind of fuel tank underneath type petrol engine base, there is pedestal (1), described pedestal (1) is flat " U " shape, by base plate (1a), front side plate (1b) and back side panel (1c) composition, two ends, left and right at described front side plate (1b) top are symmetrically arranged with journal stirrup (1d), this journal stirrup (1d) is upper offers 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, left and right at described back side panel (1c) top are symmetrically arranged with boss (1e), this boss (1e) is rearward outstanding, and offer along the vertical direction pilot hole on boss (1e).
The present invention is installed at the bottom of fuel tank, pedestal is flat " U " shape, this pedestal catches fuel tank, two journal stirrups on pedestal front side plate are corresponding with two positioning tables in two positioning blocks and petrol engine pulling plate before fuel tank, the screw wearing from front to back passes the pilot hole on the via hole on front side plate journal stirrup, mounting hole and the fuel tank positioning block on pulling plate positioning table, and front side plate journal stirrup, pulling plate positioning table and fuel tank positioning block are fixed together.Two boss on pedestal back side panel are corresponding with two locating columns on two platforms and crankcase after fuel tank, the screw wearing is from the bottom up successively through the pilot hole on back side panel boss, the via hole on fuel tank platform, and extend in the mounting hole of crankcase locating column, back side panel boss, fuel tank platform and crankcase locating column are fixed together.
As can be seen here, the present invention does not change the original structure of petrol engine, and ingeniously utilizes the mounting structure between fuel tank and pulling plate and crankcase to assemble, and not only assembling is simple, convenient, and the soundness connecting is good, can not occur loosening or come off.The present invention catches fuel tank from the bottom up, the weight of whole machine is supported by the present invention, avoid fuel tank directly to contact with ground, can effectively prevent that fuel tank from deforming or wearing and tearing, fuel tank can not be subject to the impact of complete machine operation vibration and be damaged, both improve the Security that fuel tank uses, greatly extended again the working life of fuel tank.The present invention is flat-bottom structure, large with the area of contact on ground like this, supports the good stability of whole machine.
Between two boss (1e), be provided with riser (1f), this riser (1f) by the middle part of back side panel (1c) upwards one extend and form, between described riser (1f) and boss (1e), there is gap, 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, further to improve the stability that supports whole machine.
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.
Between described front side plate (1b) and base plate (1a), have the angle of 110-120 °, described journal stirrup (1d) vertically arranges.Above structure can either guarantee that base structure is small and exquisite, can avoid again the corresponding part of front side plate and fuel tank to interfere; Meanwhile, the corresponding part of the adjacent fuel tank of front side plate, makes the combination of pedestal and fuel tank compacter.
In order to facilitate manufacturing, reduce production costs, described base plate (1a), front side plate (1b), back side panel (1c), journal stirrup (1d) and boss (1e) are by injection moulding global formation.
In order to increase structural strength, prevent that pedestal from deforming or wearing and tearing, on described base plate (1a), front side plate (1b) and back side panel (1c), be distributed with stiffening rib.
Beneficial effect: the present invention supports the weight of whole petrol engine, the good stability not only supporting, and can effectively prevent fuel tank distortion or wearing and tearing, the working life and the Security that have effectively improved fuel tank; The present invention does not change the original structure of petrol engine, and utilizes existing mounting structure on petrol engine to assemble, and dismounting is not only convenient but also quick.
