Model utility content
For solving above technical problem, the utility model provides a kind of structure simple, and good airproof performance, during oiling, does not need to turn on fuel tank cap, can carry out the available power sump filler opening sealing configuration of annotating.
Its technological scheme is as follows:
A kind of available power sump filler opening sealing configuration, comprise the filler opening be arranged on oil tank body and the fuel tank cap being arranged on this filler opening place, its key is: described filler opening extends straight up along oil tank body upper-end surface, described fuel tank cap and this filler opening stretch out the end face outer rim screw-thread fit of oil tank body, described filler opening inwall is provided with at least 2 pieces of reeds, this reed is evenly distributed on the same cross section of filler opening substantially horizontal, area after reed split is more than or equal to filler opening sectional area, every block reed lower end surface is separately installed with stage clip, this stage clip upper end is connected with described reed lower end surface, lower end is outward-dipping and be supported on the sidewall of filler opening, described fuel tank cap is equipped with connecting tube slidably.
Adopt above structure, in filler opening, reed is set, fuel tank cap installs connecting tube, during fuel up, pressure connecting tube, it is made to overcome reed and stage clip elastic force, stretching in oil tank body, can refueling operation being carried out, without the need to turning fuel tank cap, not only easy to use, and substantially increase the sealability of fuel tank.
Further, the upper stop piece vertical with this connecting tube and lower stop piece is separately installed with between described connecting tube two ends, described upper stop piece is positioned at above fuel tank cap, lower stop piece is positioned at the filler opening below fuel tank cap, and the spacing between described upper stop piece and lower stop piece is greater than the distance of reed to fuel tank cap upper-end surface.Adopt above structure, it is spacing that upper and lower catch completes the upper and lower stroke of connecting tube, can depart from reed completely when guaranteeing that connecting tube lower end is in top dead center, when being in lower dead center, can deep enough oil tank body inner.
Further, described lower stop piece lower end surface is provided with sealing gasket, this structure is when oil tank body inside is stretched in connecting tube lower end, and lower stop piece can guarantee the reliable sealing of reed connecting part.
Further, described reed is 3 pieces, and this spring surface is coated with elastic rubber layer.3 pieces of reeds make connecting tube more laborsaving when backing down reed, and when the elastic rubber layer of spring surface makes it closed, sealing effect is better.
Further, described connecting tube and fuel tank cap cooperation position are provided with stuffing box gland, to guarantee the effective sealing of fuel tank cap and connecting tube cooperation position.
Further, one end that described connecting tube stretches out fuel tank cap at it is provided with pipe cap, and this pipe cap is provided with vent.Installing pipe cap can prevent foreign matter from entering in fuel tank through connecting tube, pollutes fuel oil, and the setting of vent occurs negative pressure in the chamber in order to prevent fuel tank cap and reed from surrounding, and then upwards oil suction.
Beneficial effect: the available power sump filler opening sealing configuration adopting above technological scheme, this structure is simple, novel, does not need loosening fuel tank cap, can complete fuel filling operation, easy to use, substantially increases the sealability of fuel tank simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of oil tank body in the utility model;
Fig. 3 is the structural representation of reed distribution in the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, a kind of available power sump filler opening sealing configuration, comprise the filler opening 2 be arranged on oil tank body 1 and the fuel tank cap 3 be arranged on this filler opening 2, described oil tank body is fastened by oil tank upper body 11 and fuel tank lower body 12 and is formed, described oil tank upper body 11 is symmetrical arranged with fuel tank lower body about 12, respectively after impact briquetting, one is formed again through roll welding, described filler opening 2 is arranged on oil tank upper body 11 upper-end surface, fuel tank lower body 12 sets out hydraulic fluid port 13, this filler opening 2 extends straight up along oil tank upper body 11 upper-end surface, fuel tank cap 3 and filler opening 2 end face outer screw-thread fit.
Fig. 1 shows in detail the structure at filler opening 2 place, described filler opening 2 inwall is provided with reed 4, composition graphs 3 can be found out, reed is 3 pieces altogether, and be evenly distributed on the same level cross section of filler opening 2, described reed 4 one end and filler opening 2 inwall are welded and fixed, the other end is free end, the free end of polylith reed 4 overlaps the sealing formed filler opening 2 mutually, area after its split is more than or equal to the sectional area of filler opening 2 substantially horizontal, this reed 4 is coated with elastic rubber layer on the surface, below every block reed 4, stage clip 41 is set respectively, this stage clip 41 upper end is connected to center, described reed 4 lower end surface, lower end is outward-dipping and be fixed on the sidewall of filler opening.
Be it can also be seen that by Fig. 1, described fuel tank cap 3 center offers the connecting tube via hole of up/down perforation, and wear connecting tube 5, in this via hole, arrange stuffing box gland 7, connecting tube 5 and stuffing box gland 7 are transition fit, connecting tube 5 are provided with abreast upper stop piece 51 and lower stop piece 52, connecting tube 5 is coaxially arranged with upper stop piece 51 and lower stop piece 52, connecting tube 5 is each passed through the center of this upper stop piece 51 and lower stop piece 52, and upper stop piece 51 upper-end surface is stretched out in this connecting tube 5 upper end, and lower stop piece 52 lower end surface is stretched out in lower end.
