Description

Technical Field

[0001] The utility model belongs to the technical field of rocker arms and relates to a rocker arm structure which is easy to install. Background Art

[0002] As a necessary component of the engine, the rocker arm structure needs to move frequently during operation. The traditional rocker arm of a general small gasoline engine is connected to the rocker arm bracket in a planar motion manner. The traditional rocker arm is an integrated structure, which is connected to the intake and exhaust valves at the same time through a pin shaft on the rocker arm bracket. The rocker arm directly controls the intake valve and the exhaust valve. Since the current cylinder heads are cast in one piece, two coaxial and transverse through holes need to be opened on the cylinder head when the cylinder head is molded to install the rocker arm structure.

[0003] In view of the above problems, a rocker arm structure that is easy to install is proposed, which is convenient for installing the rocker arm structure and reduces the cumbersome process caused by opening the cylinder head mold. Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and proposes a rocker arm structure which is easy to install.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a rocker arm structure that is easy to install, including a rocker arm body, wherein the rocker arm body is provided with a rocker arm shaft, the rocker arm shaft can be removed from the rocker arm body, the rocker arm shaft includes a circular mounting block that is clearance-matched with the rocker arm body, the rocker arm body can be rotated on the circular mounting block, and one side of the mounting block is provided with a mounting plate for mounting the rocker arm body to the cylinder head.

[0006] In the above-mentioned rocker arm structure that is easy to install, a mounting hole is provided on the mounting plate.

[0007] In the above-mentioned rocker arm structure that is easy to install, a lubrication hole is opened on the top of the rocker arm body.

[0008] In the above-mentioned rocker arm structure that is easy to install, a lubrication notch is provided on the side of the rocker arm body.

[0009] Compared with the prior art, the utility model adopts a split structure for the rocker arm body and the rocker arm shaft, and enables the rocker arm body to rotate on the rocker arm shaft, and the rocker arm can be installed through the mounting plates at both ends of the rocker arm shaft, and the mounting holes on the mounting plates can be fixed thereto with bolts, thereby facilitating the installation of the rocker arm body on the cylinder head; by providing lubrication holes and lubrication gaps, the staff can introduce lubricating oil from the lubrication holes and the lubrication gaps, thereby improving the lubrication effect between the rocker arm body and the rocker arm shaft, and making the rotation between the rocker arm structure and the rocker arm shaft smoother.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Example

[0015] like Figures 1 to 3 As shown, a rocker arm structure that is easy to install includes a rocker arm body 1, characterized in that a rocker arm shaft 2 is arranged on the rocker arm body 1, and the rocker arm shaft 2 can be removed from the rocker arm body 1. The rocker arm shaft 2 includes a circular mounting block 21 that is clearance-matched with the rocker arm body 1, and the rocker arm body 1 can be rotated on the circular mounting block 21. One side of the mounting block is provided with a mounting piece 22 for mounting the rocker arm body 1 to the cylinder head 6.

[0016] Furthermore, a mounting hole 3 is provided on the mounting plate 22 .

[0017] Furthermore, a lubrication hole 4 is provided on the top of the rocker arm body 1 .

[0018] Furthermore, a lubrication notch 5 is provided on the side of the rocker arm body 1 .

[0019] The utility model adopts a split structure for the rocker arm body 1 and the rocker arm shaft 2, and enables the rocker arm body 1 to rotate on the rocker arm shaft 2, and the rocker arm can be installed through the mounting plates 22 at both ends of the rocker arm shaft 2, and the mounting holes 3 on the mounting plates 22 can be fixed to the cylinder head 6 by bolts, so as to facilitate the installation of the rocker arm body 1 on the cylinder head 6; by providing the lubrication hole 4 and the lubrication notch 5, the staff can introduce lubricating oil from the lubrication hole 4 and the lubrication notch 5, so as to improve the lubrication effect between the rocker arm body 1 and the rocker arm shaft 2, and make the rotation between the rocker arm structure and the rocker arm shaft 2 smoother.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
