Background technique
Fig. 1 and Fig. 2 show existing a kind of fuel tank switch structure.This fuel tank switch comprises housing 1, handle 2, link 3, flow pad 4 and spring 5 etc.Housing 1 has cylindrical oil suction chamber, and flow pad 4, link 3 and handle 2 are placed in this oil suction chamber successively.Flow pad 4 has a plurality of through holes 41, and partial through holes 41 wherein is communicated with the filler opening 13 of housing, and another part through hole 41 is communicated with the oil outlet 14 of housing.Link 3 is clipped between handle 2 and the flow pad 4, forms by projection on it and the mounting groove on the handle 21 circumferentially to be fixedly connected, thereby makes link 3 rotate with handle 2.The recline end face of flow pad 4 of link 3 is provided with annular groove 33.Be placed between handle 2 and the link 3 to spring 5 compressions.Handle 2 its external cylindrical surfaces are provided with the locating slot 23 of annular, come handle 2 to be installed on the housing 1 by screw 6 is screwed in restraining groove 23.Change relative position between link 3 and the flow pad 4 with the connection area between the hole 41 that changes groove 33 and flow pad 4 by handle with sleeve 2, thus realize fuel tank switch close, open or regulate the flow size.
Above-mentioned fuel tank switch only comes handle to be installed on the housing by a screw, and handle steadily also do not have some setbacks during rotation, and sealing is poor owing to single load bearing.
Summary of the invention
The handle rotation that is above-mentioned existing fuel tank switch exists to be solved by this invention does not steadily have some setbacks yet, the technical problem of sealing difference.
In order to solve the problems of the technologies described above, the present invention proposes a kind of fuel tank switch, comprise housing and be placed on flow pad in the oil suction chamber successively with oil suction chamber, link, spring and handle, housing also has filler opening and oil outlet, the oil suction chamber bottom is provided with the through hole that is communicated with filler opening and oil outlet respectively, the flow spacer has the metering orifice that is communicated with this through hole, link has annular groove at the end face of the flow pad that reclines, link and handle circumferentially are fixedly connected, handle is installed in rotation on the housing, spring is arranged between handle and the link by compression, the external cylindrical surface of handle is provided with the handle restraining groove, the sidewall of oil suction chamber is provided with and the corresponding housing restraining groove of handle restraining groove, and circlip is arranged in handle restraining groove and the housing restraining groove.
The present invention has set up handle restraining groove, housing restraining groove and circlip on existing fuel tank opening structure, further define the relative position between handle and the housing, determined the rotary motion trace of handle, made stressed even, smooth and easy, the good seal performance of stability of rotation of handle.

Fig. 7 is a link worm's eye view of the present invention.
Below in conjunction with accompanying drawing the present invention is described in detail.
Embodiment
Referring to Fig. 3, fuel tank switch comprises housing 1, handle 2, filter 6 and sediment bowl 7.Housing 1 is installed on the fuel tank by the fixed interface on it 11, installs after-filter 6 and is in the fuel tank, and the oil in the fuel tank enters housing 1 after filtering through the filter screen on the filter 6 61.
Referring to Fig. 4 and Fig. 5, housing 1 have at an upper portion thereof cylindrical oil suction chamber and its underpart go out oil pocket 12, go out oil outlet 14 and sediment bowl 7 that oil pocket 12 is communicated with housings 1 sidepiece.The bottom of oil suction chamber is provided with the through hole 15,16 that is communicated with filler opening 13 respectively and goes out oil pocket 12.The filler opening 13 of housing 1 is communicated with filter 6, and fuel-displaced 14 are communicated with oil pocket 12 and fuel tank switch outside.
Specify the mobility status of oil in fuel tank switch below in conjunction with accompanying drawing.Filter 6 is communicated with the filler opening 13 of housing 1, oil in the fuel tank enters filler opening 13 by filter 6, enter in the groove 33 of link 3 by the metering orifice 41 on filler opening 13 via through holes successively 15 and the flow pad 4 then, again successively on flow pad 4 through hole 16 of metering orifice 41 and housing 1 as go into housing 1 go out oil pocket 12, flow out housings 1 from oil outlet 14 at last.Oil at the flow circuits in the fuel tank switch shown in the arrow among Fig. 4 and Fig. 5.Groove 33 on the link 3 changes along with the rotation of handle 2 with the area that is communicated with of the through hole 16 of housing 1, groove 33 and through hole 16 to be communicated with area big more, the flow of fuel tank switch is big more, otherwise then more little.Like this, fuel tank switch by handle with sleeve 2 realized fuel tank unlatching, close and flow size control.
The present invention compares with existing fuel tank switch illustrated in figures 1 and 2, main improvement is, on the cylindrical side wall of housing 1 oil suction chamber, be provided with housing restraining groove 18, correspondingly on the cylindrical outer wall face of handle 2, be provided with handle restraining groove 24, the position of handle restraining groove 24 is all corresponding with housing restraining groove 18 with shape, and circlip 8 is placed in housing restraining groove 18 and the handle restraining groove 24.The toroidal cavity of housing restraining groove 18 for sealing on the circumferencial direction of oil suction chamber cylindrical side wall, handle restraining groove 24 are the toroidal cavity that seals on the circumferencial direction of the cylindrical outer wall face of handle 2.Circlip 8 is nonocclusive circular, can be by steel, iron or other metal, or the plastics elastomeric material is made.Circlip 8 is installed in handle restraining groove 24 and the housing restraining groove 18 by the resiliently deformable of himself, after installing, circlip 8 is all the time in handle restraining groove 24 and housing restraining groove 18, thereby further determined the relative position between housing 1 and the handle 2, improved the sealing of fuel tank switch.When handle 2 rotated, housing restraining groove 18, handle restraining groove 24 and circlip 8 had been determined the rotation track of handle 2 together jointly, and handle 2 is stressed in a circumferential direction evenly, rotates steady, smooth and easy.
In addition, the present invention has also further improved the structure of link 3, on boss 31, be provided with columned spring standing groove 34, the bottom of spring 5 is placed in the spring standing groove 34, define the position of spring 5, thereby make link 3, flow pad 4 stressed constant, even, further improved the sealing of fuel tank switch.
The foregoing description only is used for the understanding to the present invention's design, is not limitation of the present invention, and design can also have many structural simple change according to the present invention.For example, circumferentially being fixedly connected between handle and the link can realize by projection on the handle and the cooperation between the groove on the link, can adopt known other structure of those skilled in the art, connecting mode to come handle to be installed in rotation on the housing.These structural simple transformation include in protection scope of the present invention.
