Description
Technical field
The utility model relates to the structure or the installation of fuel tank, relates in particular to a kind of fuel tank positioning means.
Background technique
The orientation type of the critical component as the general gasoline engines supply system---fuel tank often need be in conjunction with lock bolt, and a plurality of parts such as fixed supported slab are finished, and its design is complicated loaded down with trivial details.For example, be that lock bolt is passed oil box now, and cooperate about lining and the pad restriction fuel tank and move forward and backward with mode; Also leave one or two journal stirrup at the fuel tank side, fuel tank is fixed on the support plate, and then limited the fuel tank inclination by bolt.Now also has another kind of mode fixed oil tank: directly stay two journal stirrups, pass through bolt at the fuel tank side.This dual mode not only all needs complicated structural design, and when blow moulding and forming, having to increases effective installation that certain wall thickness guarantees bolt hole, thereby has increased material and cost, and from technological angle, assembling is complicated loaded down with trivial details.
The model utility content
The purpose of this utility model is to provide a kind of fuel tank positioning means, and the utility model assembling is simple, can effectively locate fuel tank, realizes light dismounting.
The purpose of this utility model is achieved in that a kind of fuel tank positioning means, it is characterized in that: it comprises locking nut and the wind scooper that is used for fixing fuel tank, and wherein, the reservoir port of fuel tank stretches out the surface of described wind scooper, by cooperating, be connected on the described wind scooper with described locking nut.
Place the oil box arranged outside in the wind scooper that journal stirrup is arranged, the cushion rubber bumper of installing on the journal stirrup cooperates wind scooper to prevent that fuel tank is along self axis rotation, and then fully locate fuel tank, bigger because motor shakes in the course of the work, cushion rubber bumper can play good damping, buffering effect.
Above-mentioned locking nut is positioned in the middle of the wind scooper afterbody, and and wind scooper between also be provided with trapezoidal rubber cushion, be provided with rubbery flat gasket between wind scooper and the fuel tank, such the effect that can further play bumper and absorbing shock is set.
The bottom of above-mentioned locking nut is provided with projection, and should projection reduce gradually along the direction that locking nut screws in, and makes nut easy and convenient when assembling screws in, and has the anti-loose effect of retaining.
Above-mentioned locking nut is consistent with the selection of oil box to be good, such as adopting improved plastics structural shape, compares with metal bolts, and its cost is lower, is satisfying under the good lock ability, has lighter quality; Above-mentioned journal stirrup evenly is arranged on the casing both sides of fuel tank, cushion rubber bumper directly is pressed on the journal stirrup, since the elasticity of rubber material with and special structure, can make cushion rubber bumper combine with fuel tank closely, and cooperation wind scooper, can prevent effectively that fuel tank from producing swing in engine working process, play good damping, buffering effect.
The periphery of above-mentioned locking nut is provided with stiffening rib, in order to the intensity of raising locking nut, and for manual the screw-in provides Point of Strength, guarantees the operability that it is good.
The utlity model has following beneficial effect:
The utility model adopts a kind of novel universal petrol engine oil tank means of fixation, wherein the orientation type of fuel tank is different from conventional metals bolt type location, but employing sleeve nut from plastic material, and cooperate annex such as cushion rubber bumper, can not only effectively locate fuel tank, and the structures of using such as cushion rubber bumper more can play the effect of bumper and absorbing shock.Wherein only adopt locking nut just can finish the location of fuel tank basically, and the position of locking nut is positioned in the middle of the wind scooper afterbody, the fuel tank shoulder is stressed symmetry in the engine vibration process, and fuel tank excessive inclination can not take place.Annexes such as the cushion rubber bumper of matching design can prevent fuel tank along the rotation of self axis, and then fully locate fuel tank, and because motor shakes greatlyyer in the course of the work, annexes such as cushion rubber bumper can play good damping, buffering effect.Fuel tank positioning means in the utility model is simple in structure, and it is ingenious reasonable to design, the orientation type novelty, and structural entity is handsome in appearance.And all parts adopt plastics or/and rubber is made low cost of manufacture; Its fit is simply effective, and assembly technology has greatly been simplified in easily dismounting.
