Side, and cover board is between cylinder head and lifting lug.
Preferably, in above-mentioned technical proposal, cylinder head gear chamber sealing structure further includes O-shaped rubber ring, is set to logical
Between hole and cover board, and O-shaped rubber ring is being sealed cover board.
Preferably, in above-mentioned technical proposal, there are two limited blocks for the outside tool of cover board, and two limited blocks cover to limit
Plate moves in the axial direction.
Preferably, it is opened up in above-mentioned technical proposal, on lifting lug there are two relief hole, and two relief holes with two limiting
Position block corresponding matching, limitation cover board move in a circumferential direction.
Compared with prior art, the utility model has the advantages that：The cylinder head gear chamber of the utility model is close
Seal structure, simple in structure, installation is simple, is not required to gluing, and can repeat dismounting not part of damage, meets nonexpondable need
It wants.

Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figures 4 to 7, according to a kind of cylinder head gear chamber sealing structure of specific embodiment of the present invention,
It includes：Cylinder head 1, gear assembly 3, through-hole, cover board 5 and lifting lug.Gear assembly 3 is installed on the inside of cylinder head 1；Through-hole
