One protrusion and the second protrusion, first protrusion is identical with the rising height of second protrusion, the substrate of first protrusion
Length is more than the base length of second protrusion.
Optimally, the intermediate bar body is formed with multiple perforative waist round hole.
Further, the quantity of the waist round hole is four.
Optimally, the intermediate bar is being formed with a recess positioned at the side of the bent axle connecting pin.
Optimally, the thickness of the oil pump connecting rod is 9mm, and the width of the intermediate bar is 10mm, the bent axle connecting pin
Overall diameter be 40mm, the interior diameter of the bent axle connecting pin is 32mm, the protrusion of first protrusion and second protrusion
Height is 7mm, and the distance of the end of piston connecting pin is 90.4mm described in the distance of center circle of the bent axle connecting pin.
Optimally, protrusion recess is formed at the top of first protrusion.
Optimally, protrusion recess is formed at the top of second protrusion.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：Due in oil pump
The piston connecting pin of connecting rod is provided with the first protrusion and the second protrusion, and the first protrusion and the second protrusion role are to make oil pump
Connecting rod is easily connected on piston；The basal part of first protrusion is wider than the basal part of the second protrusion, and the effect being arranged in this way is
Facilitate oil pump link tilt to remove and install from piston.
Description of the drawings
Attached drawing 1 is a kind of front view of the preferred embodiment of oil pump connecting rod of the utility model；
Attached drawing 2 is the side view of embodiment illustrated in fig. 1；
Wherein, 1, bent axle connecting pin；2, piston connecting pin；21, the first protrusion；211, protrusion is recessed；22, second is prominent
It rises；3, intermediate bar；31, waist round hole；32, it is recessed.
Specific implementation mode
The utility model preferred embodiment is described in detail below in conjunction with attached drawing：
Oil pump connecting rod as depicted in figs. 1 and 2, its thickness are 9mm, it includes song integrally formed from bottom to top in figure
Axis connection end 1, intermediate bar 3 and piston connecting pin 2.Bent axle connecting pin 1 is formed as annular, the bent axle for being socketed in engine
On, it can be skidded off from bent axle when dismounting.Piston connecting pin 2 is used to connect in the clamping hole slot of piston in oil-feed pump, therein
Intermediate bar 3 is for connecting bent axle connecting pin 1 and piston connecting pin 2 and the transmission for carrying out power.
It is 32mm that the overall diameter of wherein bent axle connecting pin 1, which is 40mm, interior diameter,.The distance of center circle piston of bent axle connecting pin 1 connects
The threshold value for connecing end 2 is 90.4mm.
The both sides of piston connecting pin 2 are formed with the first protrusion 21 and the second protrusion 22, the first protrusion 21 and the second protrusion 22
Rising height it is identical, be 7mm, the base length of 21 to the second protrusion 22 of the first protrusion is long, the first protrusion 21 and centre
The angle that 3 surface of bar is formed is 150 °, and the angle of the second protrusion 22 and the formation of 3 surface of intermediate bar is 120 °.First protrusion, 21 He
Second protrusion, 22 role is connected in oil pump in the hole slot of piston, wherein the first protrusion 21 is set as its base length
The effect for being longer than the base length of the second protrusion 22 is to facilitate oil pump link tilt to be taken off from the hole slot of piston rod in oil pump
