Preferably, the buckle body is provided with an operation table at the rear side of the filter screen assembly support table.
The operation panel is used for operating the filter screen buckle when the filter screen assembly is replaced.
Preferably, the buckle body is fixed with a top column at two sides of the front part of the guide inclined plane.
When the oil storage chamber is installed, the top column is pressed against the inner side of the oil storage chamber.
Preferably, the bottom of the filter screen assembly supporting table is provided with an upward concave groove, and a gap is reserved between the front side of the groove and the bottom of the filter screen assembly supporting table.
Through recess and fore-set, reduced the space occupation of filter screen buckle to increased the oil storage volume of oil storage chamber, the clearance of recess front side makes recess and oil storage chamber inner chamber be linked together.
Preferably, the bottom of the filter screen assembly is fixed with a supporting seat, and the supporting seat is matched with the filter screen assembly supporting table.
Make through the supporting seat and form the space between filter screen subassembly brace table and the filter screen subassembly to it is indoor that the fuel of being convenient for gets into the oil storage.
The fuel pump assembly is characterized in that the oil storage chamber is arranged below the fuel pump core, and the oil storage chamber is used for storing oil when a vehicle is accelerated rapidly, so that the oil supply is avoided being insufficient.

Detailed Description
The invention is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
Example 1
As shown in fig. 1-6, a fuel pump assembly with a rapidly replaceable underneath filter screen assembly comprises a fuel pump body 1, a fuel pump core 2, a pressure regulating valve 3 and an oil outlet pipeline 4, wherein the fuel pump core 2, the pressure regulating valve 3 and the oil outlet pipeline 4 are arranged on the fuel pump body 1, an oil storage chamber 5 is arranged below an oil inlet of the fuel pump core 2 of the fuel pump body 1, the oil storage chamber 5 in be equipped with filter screen subassembly 6, the oil-out 61 of filter screen subassembly 6 and the oil inlet 21 phase-match of fuel pump core 2, oil storage chamber 5 is equipped with filter screen buckle 7 in filter screen subassembly 6's below, the bayonet 51 with filter screen buckle 7 assorted is seted up to the lateral part of oil storage chamber 5.
The filter screen buckle 7 comprises a buckle body 71 and a clamping head 72 matched with the bayonet 51, wherein the top of the buckle body 71 comprises a filter screen assembly support platform 73 and a guide inclined surface 74 arranged on the front side of the filter screen assembly support platform 73.
The buckle body 71 is provided with an operation table 75 on the rear side of the screen assembly support base 73.
The clip body 71 has a top post 76 fixed to both sides of the front of the guide slope 74.
The bottom of the filter screen assembly support platform 73 is provided with an upwardly concave groove 77, and a gap is left between the front side of the groove 77 and the bottom of the filter screen assembly support platform 73.
The bottom of filter screen subassembly 6 is fixed with a supporting seat 62, supporting seat 62 and filter screen subassembly brace table 73 phase-match setting.
The invention discloses a method for mounting and dismounting a filter screen assembly 6, which comprises the following steps:
