Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with embodiment.
The utility model provides a kind of and comprises connecting rod 2 for the relative wall of connect box in casing and the plate body 1 that is installed on connecting rod 2 for the washboard in casing, connecting rod 2 comprises the first pole 21, second pole 22 and connects the elastic component 23 of the first pole 21 and the second pole 22, and elastic component 23 resilient mounting is between the first pole 21 and the second pole 22.Be installed on the direction that the washboard on connecting rod 2 rocks at fuel oil and add obstruction, cut down the energy that fuel oil rocks generation, thus play the effect reducing noise.And, elastic component 23 carries out resilient mounting to the first pole 21 and the second pole 22, thus the distortion that when box deformation shrinks, washboard caused can be resisted and stress is concentrated, and what the weld nugget of the respiratory movement that can cushion fuel tank to washboard and fuel tank produced tears stress, to promote wave resistance performance and the mechanical characteristics of washboard.Meanwhile, the connecting rod 2 with elastic component 23 can be played a supporting role to casing, thus can increase the intensity of casing.
Wherein, the first pole 21 and the second pole 22 can be arranged in casing in a variety of forms, such as, arrange or mutually stagger arrange along same straight line.As one preferred embodiment, as shown in Figure 3, first pole 21 and the second pole 22 are arranged along same straight line, wherein, first pole 21 is positioned at directly over the second pole 22, and plate body 1 is installed on the second pole 22, elastic component 23 resilient mounting is between the first pole 21 and the opposed end of the second pole 22.The relative wall of connecting rod 2 connect box (is specially, the roof of the first pole 21 connect box, the diapire of the second pole 22 connect box), and elastic component 23 carries out resilient mounting to the first pole 21 and the second pole 22, thus the stress produced in casing can be resisted, also can carry out resilient mounting to increase the intensity of casing to the roof of casing simultaneously.
Further, elastic component 23 can be various ways, such as, rubber block or rubber cylinder etc., wherein, when elastic component 23 is rubber cylinder, rubber cylinder is supported between the first pole 21 and the opposed end of the second pole 22, the axis of rubber cylinder is in the bearing of trend of the first pole 21 or the second pole 22, and the two ends of rubber cylinder are connected with the end winding support of the first pole 21, second pole 22 respectively.And in a preferred embodiment, as shown in Figure 3, elastic component 23 comprises many curved bars of connection first pole 21 and the second pole 22.The upper end of curved bar is fixedly connected with the first pole 21, the lower end of curved bar is fixedly connected with the second pole 22, and the middle part of curved bar is outstanding to the direction away from connecting rod 2, can the stress between the first pole 21 and the second pole 22 effectively be cushioned by the elastic deformation of curved bar.
Wherein, curved bar can be bending bar or curvature bar, and bending bar is bent by vertical bar and forms, and form the angle of 30 ° to 150 ° between two sections of vertical bars of bending bar, and curvature bar is the strip component along curvature, the central angle of curvature bar is 30 ° to 150 °.Preferably use bending bar in the present embodiment, many curved bars (the bending bar such as shown in Fig. 3) are divided into the relative both sides (being preferably rotational symmetry to arrange) that two groups are arranged at connecting rod 2 respectively, and the curved bar being positioned at the same side is spaced, and from the inner side near connecting rod to outside, identical and the size of each curved strip increases, thus the stress can born equably between the first pole 21 and the second pole 22, realize resilient mounting effect better.Certainly, curved bar arranges with other forms and distributes also is feasible, as long as can realize the resilient mounting between the first pole 21 and the second pole 22.
Further, connecting rod 2 is formed with the weld cap 24 for welding with the relative wall of casing, weld cap 24 is arranged at the free end of the first pole 21 and the second pole 22, first pole 21 and the second pole 22 are welded with the wall of casing respectively by weld cap 24, thus it is fixing to realize washboard, and elastic component 23 just in time can cushion that weld cap 24 produces with the weld nugget of casing tears stress.Wherein, the material of washboard mostly is plastics, and welding herein mostly also correspondingly more is thermofussion welding.
In addition, in order to increase the installation strength between plate body 1 and connecting rod 2, also comprise the reinforced rib 3 extended to from connecting rod 2 plate body 1 for the washboard in casing.Meanwhile, plate body 1 offers multiple through hole, can be flowed in casing through through hole by the liquid that washboard stops, thus do not affect the serviceability of liquid while preventing the liquid spray in casing from producing noise.And the edge of plate body 1 is formed with a circle flange, and the flange of plate body 1 is set to meet the flow direction to the liquid spray usually, thus while the intensity increasing plate body 1, also can increase the area of contact between washboard and the liquid spray, and promote wave resistance effect.
Further, the utility model also provides a kind of fuel tank, and it is provided with above-mentioned for the washboard in casing.Wherein, the profile of fuel tank can be cube or cylindrical etc., or is applicable to the profiled shape of installing space of fuel tank in machinery space, and its inside is provided with for the washboard in casing, thus can reduce the noise of fuel tank.
Wherein, as shown in Figures 1 to 4, as one preferred embodiment, fuel tank is preferably formed to the shape of a saddle, it gallery 60 comprising the first branch mailbox 40, second branch mailbox 50 and be communicated with the first branch mailbox 40 and the second branch mailbox 50, extend in the second branch mailbox 50 through gallery 60 in the first branch mailbox 40 for the washboard in casing, and be provided with connecting rod 2 in the first branch mailbox 40, in gallery 60 and in the second branch mailbox 50.So be arranged so that between washboard and fuel tank, to be at least formed with six weld nuggets, washboard is stably installed in fuel tank, and each connecting rod 2 carries out resilient mounting to the first branch mailbox 40, gallery 60 and the second branch mailbox 50 respectively, thus while the stress that can produce in each branch mailbox of antagonism, strengthen the intensity of each branch mailbox.
The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
