Abstract
The utility model discloses a cylinder head cover, which comprises a cylinder head cover body, wherein the upper wall of the cylinder head cover body is provided with a through hole from which an oil atomizer wire harness passes; a counterbore used for installing a lip-shaped sealing ring is coaxially arranged above the through hole; due to the fact that the through hole is formed in the upper wall of the cylinder head cover body and the oil atomizer wire harness passes through the through hole, the connector of the oil atomizer wire harness is positioned on the outer part of the cylinder head cover body and is positioned in a larger space above the cylinder head cover body; in the space, the connector can be very conveniently plugged and unplugged; in addition, a bracket dedicated for fixing the oil atomizer wire harness can be arranged in the space for fixing the oil atomizer wire harness so as to improve the use reliability of the oil atomizer; the counterbore is formed above the through hole, and the lip-shaped sealing ring is installed in the counterbore to seal engine oil. According to the above structure, after the cylinder head cover is fixedly installed on an engine by fasteners, the cylinder head cover does not need to be disassembled, and the use convenience is improved.
Description
Technical field
The utility model relates to technical field of engines, relates in particular to the valve mechanism cover that motor uses.
Background technique
The fuel injector magnetic system of the motor of some type is positioned at valve mechanism cover inside at present, and oil sprayer wire harness mounting hole site is in rocker arm bonnet side.The plug of oil sprayer wire harness connector assembly need to be removed valve mechanism cover just can carry out.Oil sprayer wire harness is positioned at valve mechanism cover inside, because valve mechanism cover wire harness that space is limit is without fixed support, easily and the interior wall friction of rocker arm bonnet and cause the damage of wire harness.
Summary of the invention
Technical problem to be solved in the utility model is: be applicable to the valve mechanism cover that oil sprayer wire harness is installed.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of valve mechanism cover, comprise valve mechanism cover body, the upper wall of described valve mechanism cover body is provided with for the through hole through oil sprayer wire harness, and the top of described through hole is coaxially provided with for the counterbore of lip-type packing is installed.
As a kind of preferred version, the sidewall of described counterbore is higher than the upper surface of described valve mechanism cover body.
As a kind of preferred version, the sidewall of described counterbore is provided with three for the fixed hole of fixing described lip-type packing.
As a kind of preferred version, the periphery of the upper wall of described valve mechanism cover body is provided with five for the mounting hole of valve mechanism cover body is installed, and wherein two mounting hole site are in the both sides of described counterbore.
Owing to having adopted technique scheme, by through hole being set on the upper wall at valve mechanism cover body, oil sprayer wire harness passes from through hole, make the connector assembly of oil sprayer wire harness be positioned at valve mechanism cover body exterior, and the space that the top that is positioned at valve mechanism cover body is larger, in this space, the plug of connector assembly is very convenient, and can be at the support of a special fixing oil sprayer wire harness of this spatial placement, fix oil sprayer wire harness, improve the reliability that oil sprayer uses, one counterbore is set above through hole, in counterbore, install lip-type packing and be used for sealing machine oil, pass through said structure, after valve mechanism cover is fixedly mounted on motor by fastening piece, just no longer need to dismantle valve mechanism cover, improved the convenience of using.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model embodiment's plan view;
Fig. 2 be Fig. 1 along A-A to sectional view;
In figure: 1, valve mechanism cover body; 2, through hole; 3, counterbore; 4, mounting hole; 5, fixed hole; 6 sidewalls.
Embodiment
As shown in Fig. 1 and Fig. 2 are common, a kind of valve mechanism cover, comprise valve mechanism cover body 1, the upper wall of described valve mechanism cover body 1 is provided with for the through hole 2 through oil sprayer wire harness, the top of described through hole 2 is coaxially provided with for the counterbore 3 of lip-type packing is installed, the sidewall 6 of described counterbore 3 is higher than the upper surface of described valve mechanism cover body 1, the sidewall 6 of described counterbore 3 is provided with three for the fixed hole 5 of fixing described lip-type packing, these three fixed holes 5 are evenly distributed on counterbore 3 sidewalls 6, the periphery of the upper wall of described valve mechanism cover body 1 is provided with five for the mounting hole 4 of valve mechanism cover body 1 is installed, wherein two mounting holes 4 are positioned at the both sides of described counterbore 3.
During use, valve mechanism cover body 1 is passed to mounting hole 4 by bolt to be fixed in the cylinder head of motor, the wire harness of oil sprayer is drawn from through hole 2, the support of one special fixing fuel injector wire harness is set above valve mechanism cover body 1, position with constraint wire harness, the connector assembly of oil sprayer wire harness is fixed on the outside of valve mechanism cover body 1, thereby can conveniently plug, do not need to dismantle valve mechanism cover body 1, interior installation one lip-type packing of counterbore 3, installs a pressing plate by fixed hole 5 lip-type packing is fixed.
