Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model sealing gasket, comprises packing ring body 31 and is located at the mounting hole 32 on packing ring body 31, packing ring body 31 is loop configuration, can be the track type that straight line connects in the middle of circular arc for ring, ellipse, square or two ends.
The end face of the contact up and down non-planar surface of the utility model middle washer body 31, the upper and lower end face of packing ring body is respectively equipped with the projection that highly inwardly outer edge is successively decreased gradually, be that to contact up and down end face be to have protruding transitional surface to sealing gasket 3, in the time installing and using, sealing gasket 3 upper and lower end faces are squeezed, high spot is out of shape to both sides of the edge, in deformation process, plane out-of-flatness on the lower plane of the hydraulic fuel tank cap 2 contacting with sealing gasket 3 and vehicle body 1 is partially filled, thereby solves the oil impregnate problem that has gap to cause because of contact plane out-of-flatness.
The utility model provides the embodiment of two kinds, and as shown in Figure 2, the cross section of packing ring body 31 projections is the arcuate structure of smooth transition, and arcuate structure extends to inward flange by the outward edge of packing ring body 31, covers the whole upper and lower surface of contact of packing ring body 31.As shown in Figure 4, the cross section structure triangular in shape of projection, triangular structure extends to inward flange by the outward edge of packing ring body 31.Preferably, the flex point of arcuate structure or triangular apex are all located to neutral position, high near medium position, reduce gradually to two ends.High spot is located to neutral position, and arc from centre to two edges gradual change or triangular structure by, can realize uniform extruding stress deformation, ensures on surface of contact, injustice place and gap place to be filled more fully more uniformly, to obtain better sealing effect.
On packing ring body 31, be provided with some mounting holes 32, as shown in Figure 3, the through hole that mounting hole 32 is diminished to centre by two ends gradually for aperture.Mounting hole 32 is in order to pass bolt 4, mounting hole 32 is the arcuate structure outstanding to middle part along the cross section of axial direction, aperture, two ends is large, mid diameter is little, and even transition, in the time of construction bolt 4, the distortion that is squeezed of the little circular arc of mounting hole 32 middle diameter, fill thread pitch, hydraulic oil can not be oozed out from thread pitch, thereby solved this place's oil impregnate problem.The cross section of mounting hole 32 adopts arc transitional surface, can ensure stressed extruding homogeneous deformation, with blind more fully.Mounting hole 32 is evenly distributed on ring washer body 31, and multiple bolts 4 are fixed on fuel tank cap 2 on vehicle body 1 along surrounding, to realize firm stable being fixedly connected with.
In the utility model, sealing gasket 3 is ring-shaped rubber sealing gasket, and rubber is corrosion-resistant, and strength and toughness is good, and extrusion-deformation easily recovers after cancellation external force, can repeatedly use.Ring-shaped rubber sealing gasket can be designed to hollow structure, and to reduce consumptive material, weight reduction, can apply and weight is required in high sealing configuration.Sealing gasket as high-intensity in need can add metal supporting rings in hollow structure, to strengthen the intensity of sealing gasket.
The utility model gasket structure is simple, and good sealing effect can solve the oil impregnate problem that has gap to cause because of contact plane out-of-flatness; The problem of connecting thread gap location oil impregnate; The protruding structure of complete even gradual change, ensures on surface of contact, injustice place and gap place to be filled more fully more uniformly, to obtain better sealing effect.The utility model gasket structure is simple, good sealing effect, and the sealing to hydraulic oil container on application and fork truck, assembling is simple, can play the effect that well prevents hydraulic oil seepage, improves vehicle performance, has stronger practicability.
The utility model also provides a kind of fork truck, as shown in Figure 5, comprises hydraulic oil container, between the fuel tank cap 2 of hydraulic oil container and vehicle body 1, is provided with sealing gasket 3.Select the sealing gasket 3 identical with fuel tank cap 2 shapes, sealing gasket 3 has the structural feature of sealing gasket in above-mentioned the utility model.Owing to having adopted the ring structure in above-described embodiment, therefore there are all advantages of above-mentioned sealing gasket.The fuel tank cap 2 of fork truck, between sealing gasket 3 and vehicle body 1, connect by bolt 4, preferably, bolt 4 is hexagon flange bolt, the flange supporting surface that hexagonal is spread unchecked bolt is provided with an angle, in the process of locking, contact with the upper surface of fuel tank cap 2, surface of contact is little, easily locking, when increasing supporting surface, clamping force can produce certain distortion, contact laminating with the upper surface of fuel tank cap 2, the rebounding force producing can play certain locking effect, therefore adopt hexagon flange bolt can save the use of original bullet pad, avoid the oil impregnate phenomenon that has joint gap to produce between bullet pad and original plain bolt.
By reference to the accompanying drawings the utility model is exemplarily described above; but the utility model is not limited to aforesaid way; as long as adopt the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out or directly apply to other occasion, all drop in protection domain of the present utility model.
