Preferably：The body is constructed using PE, PP, EVA, PVC or ABS plastic cement material.
By adopting above-mentioned technical proposal, several annular projections, adjacent ring is arranged at intervals with the lateral wall of body
Ring-type strengthening groove is constituted between shape projection, and the groove width of ring-type strengthening groove is 1.53 and fits in the groove depth ratio of ring-type strengthening groove
Under enhancement layer on inboard wall of tube body coordinates, when the bellows is subject to oil pressure to extrude in use, ring-type strengthening groove can drive
Body has a preferable screen resilience, so that bellows is not in fracture or metaboly occurring, bulk strength is stronger, prolongs
Service life is grown, so as to extend the service life of fuel oil pump assembly；Groove width and ring-type strengthening groove such as ring-type strengthening groove
Under groove depth ratio coordinates with the enhancement layer fitted on inboard wall of tube body more than 1.53, the bellows is subject to oil pressure in use
During extruding, ring-type strengthening groove can drive body to have a poor screen resilience, so that bellows occurs that phenomenon of rupture occurs,
Bulk strength is poor, reduces service life, so as to reduce the service life of fuel oil pump assembly.Groove width such as ring-type strengthening groove
Under the enhancement layer being less than 1.53 and fit on inboard wall of tube body with the groove depth ratio of ring-type strengthening groove coordinates, the bellows is being used
During when being subject to oil pressure to extrude, ring-type strengthening groove can drive body to have a poor screen resilience, so that bellows can go out
Existing metaboly occurs, and bulk strength is poor, reduces service life, so as to reduce the service life of fuel oil pump assembly；Institute
It is 1.53 and fits in the enhancement layer cooperation on inboard wall of tube body with groove depth ratio of the groove width of ring-type strengthening groove with ring-type strengthening groove
Under, bulk strength is stronger, extends service life, so as to extend the service life of fuel oil pump assembly.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, can be with according to these other accompanying drawings of accompanying drawings acquisition.
