Problem.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of tappet body, including tappet body body, the sidewall of described tappet body body has at least one direction recess,
The length direction of described direction recess is parallel to tappet body body axis, and the lower end of described tappet body body is provided with roller and installs
Groove, and the sidewall of tappet body body lower end is downwardly extending two relative lugs, and described lug has roller pin peace
Dress hole, the upper end of described tappet body body is provided with on oil storage tank, and tappet body body and has for oil storage tank, roller being installed
The oil through that groove connection is got up, the outer wall of described tappet body body is provided with two lubricating oil holding tanks, and described lubricating oil is deposited
Storage tank is positioned on the upper end of lug, and the cell wall of lubricating oil holding tank and has the first oilhole, the hole wall of described roller pin installing hole
On have the second oilhole being connected with the first oilhole, the outer wall of described tappet body body also has annular oil groove, described ring
Shape oil groove is positioned at the top of lubricating oil holding tank, and annular oil groove is connected with lubricating oil holding tank, described tappet body body
Lower end is positioned at the both sides of lug and has lubrication groove.
As a kind of preferred version of the present utility model, described lubricating oil holding tank is rectangular configuration.
As a kind of preferred version of the present utility model, described lubrication groove is U-shaped structure.
As a kind of preferred version of the present utility model, described direction recess is U-shaped structure.
The beneficial effects of the utility model are, described a kind of tappet body is by offering lubrication on the outer wall of tappet body body
Oil holding tank, and lubricating oil holding tank is connected with roller pin installing hole, and then can subtract at roller pin surface formation lubricating oil film
Friction between trundle pin and roller pin installing hole inwall；Secondly, offering of annular oil groove enables to tappet body body and exists
Close smooth movement in cylinder；Additionally, lubrication groove is offered in the both sides of lug, it is not only convenient for processing, and makes the lubricating oil can be more
Good is lubricated between roller and cam, roller and roller pin, thus reduces between roller and cam, roller and roller pin
Friction, improve the bearing capacity of tappet body body, extend the service life of injection pump simultaneously.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.Can manage
Solving, embodiment described herein is used only for explaining this utility model, rather than to restriction of the present utility model.
Refer to shown in Fig. 1 to Fig. 3, Fig. 1 is the perspective view of this utility model a kind of tappet body；Fig. 2 is this
The front view of utility model a kind of tappet body；Fig. 3 is the cross-sectional schematic at A-A of a kind of tappet body shown in Fig. 2.
In the present embodiment, a kind of tappet body, including tappet body body 1, the sidewall of described tappet body body 1 has one
Bar direction recess 2, described direction recess 2 is U-shaped structure, and the length direction of direction recess 2 is parallel to tappet body body 1 axis,
