Abstract
The utility model provides a mounting structure of carburetor oil needle, includes plunger and oil needle, and the one end of oil needle is equipped with the recess, and the other end is the toper, is equipped with the clamp in the recess, and the one end cover that the oil needle has the recess has the spring, and the oil needle passes the oil needle hole of plunger bottom and carries on spacingly by the clamp, and the one end of spring supports and leans on the mount, and the mount is spacing by the boss of plunger inner wall. After the technical scheme of the invention is adopted, the connection between the oil needle and the plunger is more stable and reliable, and the oil needle can be effectively prevented from moving up and down in use, so that the oil supply of the carburetor is stable, the engine operates stably, and the oil consumption of the engine is reduced.
Description
Technical field
The present invention relates to Carburetor, especially the mounting structure of component on the Carburetor.
Background technique
Common flat-absorpting type plunger Carburetor is controlled air inflow and oil pump capacity by the elevating movement of plunger and spindle, thus the amount and the concentration of control inflammable mixture.Spindle is the long tapered rod how much fuel of control can be inhaled into carburetor throat, and an end of spindle is connected on the plunger, and the other end is taper and stretches into main nozzle.On existing motorcycle carburetor, spindle is connected on the plunger with the M jump ring, and spindle takes place to go here and there moving easily in the use, make the gap between spindle tapered end and the main nozzle suddenly big or suddenly small, the fuel feeding instability has influence on the stationarity of engine running, and causes oil consumption higher.
Summary of the invention
The mounting structure that the purpose of this invention is to provide a kind of carburetor needle valve, this structure make and are connected more steadily between spindle and the Carburetor plunger, and to be not easy that string takes place moving for spindle in the use.
For achieving the above object, the mounting structure of carburetor needle valve provided by the invention, comprise plunger and spindle, one end of spindle is provided with groove, and the other end is taper, and clip is housed in the groove, the end that spindle has groove is with spring, spindle passes the spindle hole of plunger base and is undertaken spacingly by clip, and an end of spring is resisted against on the fixing frame, and fixing frame is spacing by the boss of plunger inwall.
Spring among the present invention is connected between spindle and the fixing frame, spring makes clip more closely be fitted in the spindle nose end of plunger base, under the elastic force effect of spring, spindle just can not take place because of the oil pressure that is subjected to the oil nozzle place to go here and there up and down, make the gap between spindle tapered end and the main nozzle remain constant, the Carburetor fuel feeding is stable, helps to reduce the oil consumption of motor.
The said fixing frame is turriform, and the boss of plunger inwall has three and be circumferentially evenly and distribute, and has three flanges to overlap with above-mentioned boss on the fixing frame and cooperates, and has three to be circumferential equally distributed cannelure on the fixing frame, and cannelure is between flange.Stretch in the cannelure with clip during assembling plunger is clamped and put into to fixing frame, allow the flange on the fixing frame and the boss dislocation of plunger inwall, rotary fixing frame several angle then, the flange on the fixing frame has just been realized overlapping with the boss of plunger inwall and has been cooperated.
All-in-one-piece is provided with projection on the faying surface of said fixing frame flange, and the boss of plunger inwall is circumferentially carrying out spacingly by this projection to fixing frame, is convenient to assembling like this, also prevents from landing to occur between the boss of fixing frame and plunger inwall.
The technique effect that the present invention obtains is: being connected between spindle and the plunger is more steady, reliable, and spindle occurs that string is moving up and down in effectively avoiding using, thereby makes the Carburetor fuel feeding stable, and engine running is steady, and helps to reduce the oil consumption of motor.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of mounting structure of carburetor needle valve, be mainly used on the motorcycle flat-absorpting type plunger Carburetor, one end of spindle 1 is provided with groove 11, and the other end is taper, and groove is equipped with clip 2 for 11 li, the end that spindle 1 has groove 11 is with spring 3, spindle 1 passes the spindle hole 41 of plunger 4 bottoms and is undertaken spacingly by clip 2, and an end of spring 3 is resisted against on the fixing frame 5, and fixing frame 5 is spacing by the boss 42 of plunger 4 inwalls.
As Fig. 1, Fig. 2 and shown in Figure 3, fixing frame 5 is turriform, the boss 42 of plunger 4 inwalls has three and be circumferentially evenly and distribute, there are three flanges 51 to cooperate on the fixing frame 5 with above-mentioned boss 42 overlap joints, have three to be circumferential equally distributed cannelure 52 on the fixing frame 5, cannelure 52 is between flange 51.Stretch in the cannelure 52 with clip during assembling plunger 4 is clamped and put into to fixing frame 5, allow boss 42 dislocation of flange 51 and plunger 4 inwalls on the fixing frame 5, rotary fixing frame 5 several angles then, the flange 51 on the fixing frame 5 have just realized that with the boss 42 of plunger 4 inwalls overlap joint cooperates.
As Fig. 2, shown in Figure 3, all-in-one-piece is provided with projection 53 and 54 on flange 51 faying surfaces of fixing frame 5, the boss 42 of plunger 4 inwalls by projection 53 and the 54 pairs of fixing frames 5 circumferentially carry out spacing, projection 53 is than projection 54 height, flange 51 rotates to boss 42 along this end of projection 54 and cooperates during assembling, assemble rear boss 42 between projection 53 and 54, prevent from landing to occur between the boss 42 of fixing frame 5 and plunger 4 inwalls.
Under the elastic force effect of spring 3, clip 2 more closely is fitted in spindle hole 41 ends of plunger 4 bottoms, and spindle 1 can not take place to go here and there up and down, makes the Carburetor fuel feeding stable, and engine running is steady, and helps to reduce the oil consumption of motor.
