Abstract

The invention discloses a hand throttle operation mechanism, comprising: a sleeve, which is used for the fixation on a vehicle body and is rotatably equipped with a hand throttle operating lever for the connection with an engine throttle pulled line; a locking anti-loosening device, which is used for automatically locking the hand throttle operating lever upon the rotation of the hand throttle operating lever and is installed between the hand throttle operating lever and the sleeve; and a limiting device, which is used for limiting a rotation angle of the hand throttle operating lever and is installed between the hand throttle operating lever and the sleeve. The hand throttle operation mechanism is simple in structure and convenient and reliable in operation, and can freely control the opening angle of the engine oil pump pulled by the pulled line in order to realize the accurate positioning of the rotating speed of engine, in addition, the hand throttle operation mechanism is easy inbeing processed and low in manufacturing cost.

Description

technical field [0001] The invention relates to a vehicle fuel control device, in particular to a hand throttle control mechanism. Background technique [0002] The hand accelerator control mechanism is generally used on agricultural transport vehicles. It is used together with the foot accelerator to ensure that the vehicle will not turn off or reverse when braking on a hill, and it is also convenient to start and stop. The existing hand throttle control mechanism uses the handle handle to drive the spline shaft to rotate, and the spline shaft drives the roller with the ring guide groove to rotate, so as to realize the tightening and loosening of the engine oil pump cable. This structure has many parts. , needs mold production, and has the disadvantages of difficult processing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand throttle control mechanism, which has a simple structure, convenient and reliabl...
