Description
Technical field
The utility model relates to a kind of adjusting screw, more particularly, relates to a kind of Carburetor adjusting screw of petrol engine.
Background technique
The high speed fuel delivery of motor and low speed fuel delivery are controlled by the high speed adjusting screw and the low speed adjusting screw of Carburetor respectively, make Carburetor provide suitable fuel oil by adjusting high speed adjusting screw and low speed adjusting screw, thereby make motor reach best working state to motor.
At present, the adjusting screw of conventional construction generally adopts the metal threaded direct cooperation of the metal threaded and Carburetor of adjusting screw body, therefore, causes gas leakage easily.Especially when high engine speeds turned round, if rotating speed surpasses 10000 rev/mins, at this moment, because the influence of being vibrated, the high speed adjusting screw and the low speed adjusting screw of Carburetor were easy to generate rotation, thereby influence the performance of motor.In addition, the adjusting screw on the Carburetor adopts spring mechanism more, sees Fig. 1.Adopt the adjusting screw of spring mechanism to have following situation: 1, too many if adjusting screw is locked in the Carburetor, then spring can produce doubling-up; 2, if adjusting screw is locked in the Carburetor very little, adjusting screw is rotated and influence the performance of motor; 3, spring is aging easily; 4, spring itself can not play the effect of sealing.How to solve the problems of the technologies described above, become problem demanding prompt solution.
The model utility content
Technical problem to be solved in the utility model provide a kind of simple in structure, can prevent to become flexible and the Carburetor adjusting screw of good sealing effect.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
A kind of Carburetor adjusting screw comprises body, and the body front end is provided with the adjusting section of band tapering, and the body rear end is provided with the head that is used to adjust, and body surface is provided with no thread section and thread section; Also be provided with the nonmetallic material section on the body surface, this nonmetallic material section is by the grooving that is arranged on the body surface, and the nonmetallic material body that is located on the grooving is formed.
Further, described nonmetallic material body be shaped as shape of threads, or be no shape of threads.
Further, described grooving is the grooving along the body axial surface, or is the grooving along the body radial surface.
Further, described nonmetallic material section is positioned between described head and the thread section.
Further, described nonmetallic material section is positioned between described no thread section and the thread section.
Further, described thread section has two, and the nonmetallic material section is positioned between two thread sections.
Further, described nonmetallic material section is positioned at described head and does not have between the thread section.
Further, described nonmetallic material body is made by plastics or other nonmetallic material.
The utility model is owing to adopted said structure, body surface to be provided with the nonmetallic material section, and the nonmetallic material section is by the grooving that is arranged on the body surface, and the nonmetallic material body that is located on the grooving is formed.For example, grooving is along the grooving of body axial surface or is the grooving along the body radial surface that it can be processed arbitrarily, simultaneously, the nonmetallic material body can be located on the grooving by adopting any technology mode.When the body of adjusting screw of the present utility model was locked the metal threaded hole of Carburetor, the nonmetallic material body contacted with the internal thread of Carburetor.Because the material of nonmetallic material body and Carburetor and shape is different, make the metal internal thread of nonmetallic material body and Carburetor produce extruding, play sealing and prevent the purpose of rotating, the Carburetor that produces leaks gas thereby the utility model has overcome that the Carburetor metal internal thread in the conventional art cooperates with the adjusting screw metal external thread and problem such as adjustment susceptibility.Because the nonmetallic material section can be positioned at the diverse location of body surface, so the utility model is easier to satisfy the different requirements of moment of rotation and processing technology.Because head has adjustable shape, therefore, the utility model is fit to multiple adjustment instrument, and it is very easy to use.The utility model is simple in structure.
After the detailed description of reading mode of execution of the present utility model in conjunction with the accompanying drawings, it is clearer that characteristics of the present utility model and advantage will become.
