Description
Technical field
The utility model relates to the petrol engine technical field.
Background technique
Existing control mechanism makes general-purpose petrol engine when cold machine starts, and must petrol engine be started the manual-lock chock plate, does not close when putting in place when closing chock plate or chock plate, and motor does not just start; Complicated operation when general-purpose petrol engine starts, strongly professional, the popularization of unfavorable product; In addition, existing mechanism complexity, assembling are complicated, precision prescribed is high, and engine speed is wayward, cost is higher, general-purpose petrol engine is when being in warm boot, start quite difficulty, easily stop working when running into bigger load, the speed adjusting performance of motor is poor, complex operation in the using process, be difficult to control, the rate of fault height is a great problem that Chinese general-purpose petrol engine is difficult to go abroad.
The model utility content
The utility model purpose is to invent the choke valve control mechanism that a kind of easy operating, automation are strong, can thoroughly solve the general-purpose petrol engine of warm boot difficulty.
The purpose of this utility model is achieved through the following technical solutions: the choke valve control mechanism of general-purpose petrol engine, comprise bimetallic strip, hinged speed governing fan blade on the fan blade set screw, be fixed on the speed-regulating rack on the fan blade set screw, the fixedly connected foot piece of an end at the speed governing fan blade, on speed-regulating rack, be hinged a main fork and a secondary fork respectively, the middle part of described main fork is hinged and connected on the speed-regulating rack, one end of main fork is arranged in foot piece one side of speed governing fan blade, extension spring two is set between the other end of main fork and the speed-regulating rack, the middle part of described secondary fork is hinged and connected on the speed-regulating rack, secondary fork is provided with two side pawls, wherein between a side pawl and the speed-regulating rack extension spring three is set, other two side pawls are arranged in two outsides of the main fork that connects extension spring two, and wherein a side pawl and choke linkage are hinged.
Between above-mentioned main fork and the speed-regulating rack extension spring one is set also, this extension spring one and the homonymy of extension spring two at the hinged point of main fork.
When petrol engine is shut down; extension spring two pulls to extension spring 21 sides with an end of main fork; this end of main fork pushes secondary fork and rotates; make the secondary swing link end part that connects choke linkage push lean on an end of extension spring two to; choke linkage is closed chock plate so fully simultaneously to extension spring 21 lateral movements.Extension spring three will guarantee that carburetter choke closes reliably.And the other end of main fork with the speed governing fan blade push to bimetallic strip and near.
When the cold machine of petrol engine started, bimetallic strip was not subjected to the i.e. not distortion of heat energy, and the speed governing fan blade does not promote main fork, and main fork does not promote secondary fork, secondary fork also promotes the choke linkage that is attached thereto, and choke linkage is closed carburetter choke fully, is convenient to cold machine and starts smoothly.
When petrol engine during at warm boot, bimetallic strip is subjected to the heat energy of motor self and bending and promote the speed governing fan blade, the speed governing fan blade then promotes main fork, and main fork promotes secondary fork successively, and the choke linkage that secondary fork is attached thereto moves to extension spring two directions.Make carburetter choke be in semi-closed state like this, so that hot machine starts smoothly.
Working principle of the present utility model: when motor does not turn round, the speed governing fan blade leans on mutually with bimetallic strip, main fork leans on mutually with the afterbody of speed governing fan blade under the effect of extension spring two, the other end of main fork leans on mutually with a side of secondary fork, choke linkage is closed chock plate under the effect of extension spring three, after general-purpose petrol engine starts, the wind-force of cooling fan of engine will blow speed governing fan blade and the motion of bimetallic strip opposite direction, the speed governing fan blade will overcome the pulling force of extension spring two and move, the other end of main fork will promote secondary fork and move to the Carburetor direction, after treating that advance surpasses the central point of extension spring three, extension spring three will be moved to opposite side, the choke linkage that is attached thereto also will be opened carburetter choke like this to the motion of Carburetor direction, the normal and running of motor.
The utility model compared with prior art has following advantage:
The utility model does not need manual control, can control chock plate automatically according to the cold and hot situation of gasoline general purpose engine, and guarantee smooth ato unit, and mechanism is simple, and cost is low, stable performance.
