Plastic fuel tank shape mostly is irregularly shaped, mainly adopts the blow molding process of six layers of co-extrusion to produce, and plastic fuel tank is generally arranged in the position in portion rearward under chassis.The plastic fuel tank of part nominal volume less (about 40L or following) is designed can four corners of blow molding, directly vehicle body is fixed to by bolt again after punching, but the many employings of most plastic fuel tank two fuel tanks are fixed steel band and directly tied up fuel tank at body bottom section, and four attachment points of fixing steel band are fixed in vehicle body screw or corresponding structure by the structure of bolt or hole pin.The fixed form of existing employing two steel band fixed plastics fuel tanks, in certain extreme cases (as sharp impacts etc.), easily there is play in fuel tank, even from then on skid off in space in the space that steel band and vehicle body surround; If steel band position undesirable (as two steel bands are fixed on the position, two edges of fuel tank) or fuel tank shape too flat, there is play or the possibility that skids off larger; And fuel tank causes fuel tank damaged and leakage of oil once skid off just may have, and then the risk of catching fire.
Summary of the invention
The utility model devises a kind of novel plastic fuel tank fixed sturcture, which solves in certain extreme cases, and as sharp impacts etc., fuel tank easily in the space that steel band and vehicle body surround, play occurs, the problem even from then on skidded off in space.
In order to solve the technical matters of above-mentioned existence, the utility model have employed following scheme:
A kind of novel plastic fuel tank fixed sturcture, comprise right fixing steel band (4) and steel band (5) is fixed on a left side, it is characterized in that: also comprise the plastic stent (2) being fixed on plastic fuel tank (1) front end, plastic stent (2) is provided with a waist through hole to coordinate with bolt, plastic stent (2), right fixing steel band (4) and a left side are fixed steel band (5) and are connected by bolt and body bottom panel (6) and are fixed on body bottom panel (6) by plastic fuel tank (1).
Further, be embedded with metal grommet (3) in plastic stent (2) waist through hole, metal lining (3) is the metal collar of a kidney-shaped.
Further, metal lining (3) having coating layer on surface is with antirust.
Further, plastic stent (2) waist through hole periphery is provided with reinforcement structure.
Further, plastic fuel tank (1) adopts six layers of coextrusion blow shaping, and the body front end of plastic fuel tank (1) generates a block welding boss, and plastic stent (2) adopts the mode of hot plate welding to be welded on this welding boss.
Further, weld boss periphery and be provided with reinforcement structure.
Further, plastic stent (2) adopts the material with plastic fuel tank (1) homogeneity.
Further, the two ends fixed pan that steel band (5) is fixed on right fixing steel band (4) and a left side is provided with brace panel, and all with a circular fixation hole, all there is flange the both sides that steel band (5) is fixed on right fixing steel band (4) and a left side.
Further, steel band (5) having coating layer on surface is fixed with antirust in right fixing steel band (4) and a left side.
Further, right fixing steel band (4) and a left side are fixed steel band (5) and are all adopted thickness to be that the steel plate punched of 1.5mm is shaping.
Right fixing steel band 4, left fixing steel band 5 and plastic stent 2 are connected fastening bolt tightening order with body bottom panel 6: the bolt at plastic stent 2 place is first twisted in advance, then the right side is fixed the bolt tightening that steel band 5 is fixed on steel band 4 and a left side, finally again by the bolt tightening at plastic stent 2 place.
This novel plastic fuel tank fixed sturcture has following beneficial effect:
The utility model plastic fuel tank fixed sturcture, except fixing steel band four attachment points, increase an attachment point again fuel tank is directly fixed on vehicle body, when colliding, except two fuel tanks are fixed except the binding effect of steel band, the plastic stent newly increased can play the effect pulling fuel tank simultaneously, when sharp impacts occurs, this fixed sturcture can actv. restriction plastic fuel tank side-play amount, prevent fuel tank from fixing play in steel band at fuel tank, even skid off, then avoid because of fuel tank skid off after may be damaged and leakage of oil risk on fire occurs.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 to Fig. 2 shows a kind of novel plastic fuel tank fixed sturcture, comprises plastic fuel tank 1, plastic stent 2, right fixing steel band 4, left fixing steel band 5 and some bolts 7.Plastic stent 2 is welded on the front end of plastic fuel tank 1, plastic stent 2 is provided with a waist shaped hole, and in this waist shaped hole an embedded metal grommet 3.During installation, first pass this metal grommet 3 with a bolt 7, twist in advance after being connected with the screw matched on body bottom panel 6, and then fix steel band 5 with right fixing steel band 4 and a left side plastic fuel tank 1 is tied on body bottom panel 6, fix the circular hole of steel band 5 end respectively through right fixing steel band 4 and a left side with bolt 7, be connected fastening with the panel beating with screw on body bottom panel 6, finally the bolt 7 at metal grommet 3 place tightened.
