Abstract
The invention relates to an adjustable cavity shrinkage rod of a main nozzle, comprising a knocking head, an adjusting rod, a main body, a limit head, a spring, a rod casing and a hand disc. The adjustable cavity shrinkage rod is characterized in that the knocking head is fixedly connected with the main body by threads, the limit head and the spring are arranged inside the main body, the adjusting rod and the knocking head are movably and adjustably connected by threads, and the rod casing is riveted with the hand disc. The main nozzle is taken down after a carburetor is disassemble, the upper end of the main nozzle is put into a 5mm through hole, a 4mm through hole or a 5.5mm through hole of a sizing block according to the type of the main nozzle, the hand disc is rotated by heads so as to adjust the adjusting rod, the adjusting rod is rotated clockwise to move downwards to drive the limit head to move downwards, the adjusting rod is rotated counterclockwise to move upwards, and the limit head shrinks inwards under the action of the spring, therefore, the change of the limit head at any points between an A end and a B end is realized so as to achieve the function of adjusting the size of the limit head.
Description
Technical field
The present invention relates to petrolic carburetor maintenance tool, is a kind of main burner shrinkage cavity rod of regulating concretely.
Background technology
The motorcycle overwhelming majority is used the carburetor fuel feeding, the carburetor simple structure, easy to maintenance, but there is obvious weak point: inevitably want pine to subtract throttle during owing to motorcycle driving, at high rotating speed during to slow-speed of revolution transition, because the suction that engine produces is greater than the air inlet of carburetor, fuel oil is sucked engine through main burner in a large number; Differed by precision of manufacturing process, atomizer becomes irregular circle, worn and torn by gasoline with carburetor, and injector orifice is bigger than normal to cause oil consumption big, seriously polluted.This can regulate main burner shrinkage cavity rod mainly come from the main burner shrinkage cavity rod of inventor in the patent of invention 2009103044674 that on July 17th, 09 application has been authorized in actual use the drawback that can not regulate of pilot pin size improve and form.
Summary of the invention
The object of the present invention is to provide a kind of main burner shrinkage cavity rod of regulating, make on the structure basis of invariable that guarantees former carburetor, also have the carburetor of raising precision, reduce oil consumption, reduce exhaust emissions, can be used as the gasoline engine carburetor fuel-economizing maintenance tool.
The present invention realizes with following technical scheme: this a kind of main burner shrinkage cavity rod of regulating is made up of striking head, adjusting rod, main body, spacing head, spring, bar cover, setting stick.It is characterized in that: striking head is that screw threads for fastening is connected with main body, and spacing head and spring are installed in the inside of main body, and adjusting rod and striking head are movable adjustable being threaded, bar cover and setting stick riveted joint.Carburetor is decomposed, take off main burner, model according to main burner, the upper end of main burner is put into through hole or the through hole of 4mm or the through hole of 5.5mm of the 5mm of parallels, rotate setting stick by hand, so that reach adjustment to adjusting rod, clockwise adjusting rod moves down and drives spacing head and move down, being rotated counterclockwise adjusting rod moves up, effect lower limit potential head at spring contracts inward, thereby realizes that the arbitrfary point of spacing head between side a and b changes, so that reach the function to spacing size adjustment, after the adjustment, handle panel together takes out together with the bar cover.Regulating main burner shrinkage cavity rod perpendicular to main burner, knock gently with adz-eye hammer and can regulate main burner shrinkage cavity rod, the limit rotation can be regulated main burner shrinkage cavity rod when knocking, to guarantee evenly dwindling of main burner, the reduction volume of main burner is with the benchmark that is adjusted to of spacing head, and spacing head can be measured the fit clearance of main spindle and main burner earlier before regulating, so that guarantee that the size of spacing head is consistent with main spindle.
Beneficial effect: this a kind of main burner shrinkage cavity rod of regulating has the function that can regulate spacing head size.
Description of drawings
Accompanying drawing is a kind of structure chart of regulating main burner shrinkage cavity rod of the present invention.
1. striking head among the figure, 2. adjusting rod, 3. main body, 4. spacing head, 5. spring, 6. bar cover, 7. setting stick.
The specific embodiment
Accompanying drawing is a kind of structural map of regulating main burner shrinkage cavity rod of the present invention, is made up of striking head 1, adjusting rod 2, main body 3, spacing 4, spring 5, bar cover 6, setting stick 7.In the accompanying drawings, striking head 1 and main body 3 be for screw threads for fastening is connected, and spacing 4 and spring 5 are installed in the inside of main body 3, and adjusting rod 2 and striking head 1 are movable adjustable being threaded, bar cover 6 and setting stick 7 riveted joints.
Spacing 4 A end 2mm, B holds 2.5mm.
20 ° at oblique angle, main body 3 below.
The bottom shape of bar cover 6 and the end shape of adjusting rod 2 match.
The present invention assembles with following steps: adjusting rod 2 is spun on the striking head 1, and spring 5 is enclosed within earlier and is placed on together on spacing 4 in the main body 3 again, then main body 3 is tightened on the striking head 1; Setting stick 7 and the riveted joint of bar cover 6 usefulness boards form.
Claims (3)
1. can regulate main burner shrinkage cavity rod for one kind, form by striking head, adjusting rod, main body, spacing head, spring, bar cover, setting stick, it is characterized in that: striking head is that screw threads for fastening is connected with main body, spacing head and spring are installed in the inside of main body, adjusting rod and striking head are movable adjustable being threaded, bar cover and setting stick riveted joint.
2. a kind of main burner shrinkage cavity rod of regulating according to claim 1 is characterized in that: the A end 2mm of spacing head, B holds 2.5mm.
