Detailed description of the invention
Below, with reference to accompanying drawing, preferred implementation of the present utility model is described in detail.
Accompanying drawing shows the preferred implementation being implemented on by the utility model and being arranged on and being used between Fuel Tank and driving engine when the liquid fuel in described Fuel Tank being supplied to the fuel supply device of driving engine with predetermined flow, fuel supply device is formed with housing 1, described housing 1 has housing body 11 and lid 2, the upper surface open of housing body, have bottom and inside is formed with fuel storage groove 12, lid utilizes setting tool (fixture) 6 by the opening 13 of packing ring 3 hermetic covering shell main body 11.
And, the various parts (not shown) such as petrolift are accommodated in described housing body 11, fuel intake 15 such as from the side 14 being formed in described housing body 11 imports fuel, and sprays fuel from projecting fuel nozzle 21 on lid 2.
Especially, in the present embodiment, on the desired location of the edge of opening 16 of housing body 11, one is formed with locating dowel pin 4 highlightedly, simultaneously lid 2 relative with the edge of opening 16 of described housing and the flange 22 abutted is formed with the knock hole 5 of confession described locating dowel pin 4 intercalation.
Therefore, lid 2 is being covered in the operation in described housing body 11, by being inserted in the knock hole 5 be formed on described lid 2 by projecting locating dowel pin 4 on the edge of opening 16 of housing body 11, lid 2 is installed to the pre-position of housing body 11.
Then, by setting tools 6 such as the such as fixtures that arranges in addition, lid 2 is fixed to housing body 11, as shown in Figure 4 simultaneously, by by, projecting locating dowel pin 4 (as shown in Figure 2) compression on the edge of opening 16 of housing body 11 outstanding from the knock hole 5 be formed on described lid 2, form outstanding compressed part 41 to seal.
According to the present embodiment, obviously can seal simply and reliably, because projecting locating dowel pin 4 in housing body 11 is fixed in predetermined intercalation position, therefore also have concurrently lid 2 effect fixing with housing body 11.
In addition, when lid 2 is deliberately opened post sales, compressed part 41 is destroyed, and therefore easily can confirm that lid 2 is opened, and once lid 2 is opened, compressed part 41 is destroyed, and cannot again compress.
And, in the present embodiment, as shown in Figure 5, locating dowel pin 4 is made up of the large-diameter portion 42 being formed in base end side and the minor diameter 43 that is formed in its front, as shown in (b) of Fig. 3 and (b) of Fig. 4, knock hole 5 for the intercalation of described locating dowel pin 4 is formed with the large-diameter portion 52 and minor diameter 53 that coordinate with described locating dowel pin 4 continuously, reliably carries out intercalation support, therefore reliably lid 2 can be arranged on position accurately in two places of different bore.
Especially, in the present embodiment, the cross section of the large-diameter portion 42 of described locating dowel pin 4 is rounded, and the cross section being formed in the minor diameter 43 in its front excises from center to longitudinal predetermined altitude the semicircle that a semidiameter formed in by described large-diameter portion 42, therefore described large-diameter portion 42 and described minor diameter 43 can be formed by one-body molded in advance, also can be formed by other manufacturing process such as cuttings.
In addition, in the present embodiment, the central axis forming the described large-diameter portion 42 of locating dowel pin 4 and the large-diameter portion 52 of minor diameter 43 and knock hole 5 and minor diameter 53 staggers, and therefore lid 2 can be arranged on position very accurately.
In addition, for compression, when locating dowel pin 4 is formed by metal, adopting existing known approaches such as beaing, when locating dowel pin is formed by synthetic resin, adopting the existing known approaches such as hot melt, therefore without the need to being particularly limited to material.
In addition, in the present embodiment, to needing airtight or fluid tight the fuel supply device covering lid 2 to be described, but be not limited thereto, obvious the utility model can be applied to housing body and the lid of various uses.
In addition, the situation this embodiment illustrates and form locating dowel pin 4 in housing body 11, forming knock hole 5 on lid 2, but obviously can be implemented on equally and on lid 2, form locating dowel pin 4 on the contrary, in housing body 11, form the situation (not shown) of knock hole 5.
In addition, in the present embodiment, by compressing positioning pin 4, the fixed effect of lid 2 can be improved, and when increasing the quantity of locating dowel pin 4, not only can improve positioning precision when being covered in housing body 11 by lid 2, can also fixed effect be increased, therefore such as also can replace setting tool to use.
