Abstract
The utility model relates to a built-in rigid connection device of a plastic fuel tank, belonging to the technical field of the plastic fuel tank. The built-in rigid connection device of a plastic fuel tank comprises a support bar and bowl seats connected to two ends of the support bar. The support bar has a tubular structure, two ends of the support bar are connected to the bowl bottom center of each bowl seat, respectively, a bowl body is between the bowl bottom and the bowl mouth, multiple waist-shaped holes are uniformly arranged on the bowl body, respectively, and the waist-shaped holes on each bowl body are located on the same circumference and extend along the circumferential direction of the bowl body, respectively. When mounting, the bowl seat is located inside a hot high-density polyethylene parison, the bowl mouth is attached to the inner wall of the parison, the mold corresponding to the parison is provided with a disc structure with a groove, the shape and size of the groove match the bowl mouth of the bowl seat, and a certain force is applied, to extrude the hot parison into the bowl mouth and extrude out from the waist-shaped hole, so as to firmly combine the bowl seat and the inner wall of the parison. The device can greatly improve the rigidity and strength of the tank body, and occupies a small volume of the tank body.
Description
Technical field
The utility model relates to a kind of plastic fuel tank, particularly a kind of built-in device that is rigidly connected of plastic fuel tank.
Background technology
The inner maximum pressure scope of tradition fuel tank in order to improve the rigidity of traditional fuel tank, adopts the Kiss-off structure at-2.5-10KPa usually, and the Kiss-off structure is meant in the fuel tank forming process a kind of structure that fuel tank upper and lower surfaces regional area is realized welding.The Kiss-off structure is to come out through mould molding, and the corresponding frustum of a cone is arranged respectively on the cope and drag pattern tool, when matched moulds, promptly can on fuel tank, form this structure, does not need other frock.Adopt this kind structure to have a series of shortcoming, for example manufacturability poor, sacrifice nominal volume, acutely be easy to generate little wall thickness regions etc. because parison stretches, also there is bigger limitation the position of its layout.
The parts in the casing and the connection mode of inner wall of oil tank mainly contain two kinds.A kind of is the hot plate welding manner, can adopt manipulator to go deep into the inner wall of oil tank welding, perhaps adopts the two-piece type blow molding process to be welded on the parison, and its pulling capacity is approximately 3000N.Another kind of be the welding mode, be provided with some pits with the contact surface of fuel tank, under certain pressure, get in the parison of heat, its pulling capacity probably has 2000N.For improving the rigidity of casing, need relative inner wall of oil tank is coupled together, above-mentioned two kinds of connection mode out of reachs require or poor.
The utility model content
The purpose of the utility model is, overcomes the problem that exists in the prior art, and a kind of built-in device that is rigidly connected of plastic fuel tank is provided, and its Joint strenght is high and little to the volume influence of fuel tank.
For solving above technical matters; The built-in device that is rigidly connected of a kind of plastic fuel tank that the utility model provided comprises strut bar and is connected the bowl seat at strut bar two ends that said strut bar is a tubular structure; The two ends of strut bar are connected to the bowl center, the end of each said bowl seat; Be a bowl body between bowl end of said bowl of seat and the rim of a bowl, evenly be provided with a plurality of waist shaped holes respectively on the said bowl body, the waist shaped hole on each bowl body is positioned on the same circumference and the circumferencial direction extension of the said bowl in edge body respectively.
With respect to prior art, the utility model has been obtained following beneficial effect: during installation, the bowl seat is positioned at the high density polyethylene (HDPE) parison inside of heat; The rim of a bowl is pasting the parison inwall, on the cooresponding mould of this place's parison, is provided with the disc structure of band groove, and the geomery of groove is suitable with the rim of a bowl of bowl seat; Apply certain force; The parison of heat will be got in the rim of a bowl, and from waist shaped hole, extrudes, thereby makes bowl seat and parison inwall mortise.Adopt this connecting device can improve the rigidity of casing greatly, and the volume that takies casing seldom.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation, accompanying drawing only provides reference and explanation usefulness, and is non-in order to restriction the utility model.

Fig. 4 is the block diagram one of Fig. 3.
Fig. 5 is the block diagram two of Fig. 3.
Among the figure: 1. strut bar, 2. at the bottom of bowl seat, the 2a. bowl, 2b. the rim of a bowl, 2c. waist shaped hole, 3. parison.
The specific embodiment
Extremely shown in Figure 5 like Fig. 1; The built-in device that is rigidly connected of the utility model plastic fuel tank comprises strut bar 1 and is connected bowl seat 2 (end only is shown among the figure) at strut bar two ends that strut bar 1 is a tubular structure; The two ends of strut bar 1 are connected to the bowl center, the end of each bowl seat 2; Between the bowl end 2a of bowl seat 2 and the rim of a bowl 2b be a bowl body, evenly is provided with a plurality of waist shaped hole 2c respectively on the bowl body, and the waist shaped hole 2c on each bowl body is positioned on the same circumference and respectively along the circumferencial direction extension of bowl body.Strut bar 1 can adopt metallic material, also can be plastics, as adopting the polyformaldehyde of Shooting Technique moulding.
During installation, bowl seat 2a is positioned at the high density polyethylene (HDPE) parison inside of heat, and the rim of a bowl 2b is pasting parison 3 inwalls; The disc structure that on the cooresponding mould of this place's parison, has groove; The geomery of groove is suitable with the rim of a bowl of bowl seat 2a, applies certain force, and the parison of heat will be got in the rim of a bowl 2b; And from waist shaped hole 2c, extrude, thereby make bowl seat and parison inwall mortise.
The above is merely the preferable possible embodiments of the utility model, non-so the limitation the utility model scope of patent protection.Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
