Description

Technical Field

[0001] The utility model relates to the field of gasoline cylinder head covers, in particular to a throttle control assembly. Background Art

[0002] The throttle, also known as the "throttle valve", refers to the operating device that controls the power (thrust) of the cylinder head cover. On the piston cylinder head cover, the throttle controls the throttle opening of the carburetor to control the filling amount of the cylinder, thereby determining the output power of the cylinder head cover. On the gas turbine cylinder head cover, the throttle controls the metered fuel flow of the fuel regulator, thereby determining the thrust generated by the cylinder head cover. The throttle position controls the throttle lever, which is transmitted to the carburetor or fuel regulator on the cylinder head cover for control through the control system components such as pull rods, rocker arms, torque tubes, cables, pulleys, and fan wheels.

[0003] The existing throttle control assembly is an alloy rod similar to a handle, which is fixed to the top of the cylinder head cover by a gasket bolt and driven by a connecting rod structure. However, its structure cannot be used for a micro-tiller and can only achieve a single control of the cylinder head cover thrust. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing throttle control combination structure is single and can only be used for some generator sets, and cannot be used for terminals such as micro-tillers, water pumps, lawn mowers, etc., and the tensile force on the throttle line is relatively large.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: a throttle control assembly is provided, including a box bottom plate, a cylinder head cover is fixedly connected to the top of the box bottom plate near the left side, a fuel tank body is fixedly connected to the top of the cylinder head cover, a fitting piece is abutted against the front end of the fuel tank body near the bottom, a fixing bolt is rotatably connected to the rear end of the fitting piece, a gasket bolt is rotatably connected to the top of the fitting piece near the center, an extrusion piece is rotatably connected to the outside of the gasket bolt, the extrusion piece abuts against the top of the fitting piece, the extrusion piece is designed in an "L" shape, and the right side of the extrusion piece is near the top of the front end A wire fixing hole is provided at the bottom, the extrusion piece is slidably connected to a limit rod inside, the limit rod is fixedly connected to the top of the fitting piece, a return spring is sleeved on the outside of the limit rod, one end of the return spring is fixedly connected to the right side of the extrusion piece, the return spring is fixedly connected to the left side of the limit rod away from the extrusion piece, a throttle grip is slidably connected to the top of the extrusion piece, a pressing gasket is fixedly connected to the top of the throttle grip near the left side, the throttle grip and the pressing gasket are rotatably connected to the outside of the gasket bolt, and an engaging opening is provided at the rear end of the pressing gasket near the right side, and the engaging opening is engaged with the front end of the extrusion piece.

[0006] The above parts are used to fix the throttle cable outside the cable fixing hole. The throttle grip is used to control the pressing gasket to drive the extrusion plate to squeeze the return spring through the fitting opening to stretch the throttle cable. This solves the problem that the cable can easily be worn out and cannot be reset in time due to the single cable structure in the past, thereby improving the throttle control effect.

[0007] The utility model is further configured that a grip fixing hole is opened at the top of the throttle grip near the left side, the top of the grip fixing hole is larger than the bottom, and a wire pressing plate is abutted against the top of the bonding sheet near the front end.

[0008] The utility model is further configured that a pressing plate fixing hole is opened on the top of the pressing plate, a wire ring is fixedly connected to the top of the throttle grip near the left side, and the pressing plate is designed in an "n" shape.

[0009] The above parts realize the fixing effect of the throttle cable and the return spring, solve the problem of damage caused by large pulling force caused by directly fixing it to a handle in the past, and increase the service life of the throttle grip.

[0010] The utility model is further configured such that a fuel tank cap is rotatably connected to the top of the fuel tank body near the rear end, an exhaust pipe is fixedly connected to the front end of the cylinder head cover near the left side, the exhaust pipe is communicated with the cylinder head cover, and a muffler is fixedly connected to the top of the exhaust pipe.

[0012] The utility model is further configured that the starting assembly includes a pull plate, a steel cable is wound inside the pull plate, and a starting handle is fixedly connected to one end of the steel cable away from the pull plate, and the starting handle abuts against the rear end of the pull plate near the top.

[0013] The utility model is further configured that a one-way valve is provided on the top of the oil tank body, the one-way valve is connected to the gas oil tank body, and a filter assembly is provided on the top of the one-way valve.

[0014] The utility model is further configured such that the filter assembly includes a one-way valve tube, one end of the one-way valve tube is fixedly connected to the top of the one-way valve, one end of the one-way valve tube away from the one-way valve is fixedly connected to an air filter, and the air filter is fixedly connected to the front end of the air guide cover near the top.

[0015] The above parts realize the filtration of air entering the cylinder head cover and the treatment of exhaust gas, which solves the problem of reduced wear life of the cylinder head cover due to particulate impurities in the inhaled air and increases the service life of the cylinder head cover.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model ensures that the throttle cable is effectively pulled when the equipment is in operation by passing the throttle cable through the cable pressure plate and winding it around the cable fixing hole, thereby solving the problems of excessive tensile force causing damage to the throttle cable and no idling caused by simply fixing the throttle cable in the past, and the throttle lever cannot be used for terminals such as micro-tillers, water pumps, and lawn mowers at the same time, thereby increasing the usage scenarios of the throttle lever.
