Description
Technical Field
The invention relates to a plunger oil needle matching structure of a carburetor.
Background
The carburetor is a mechanical device which mixes gasoline and air in a certain proportion under the action of vacuum generated by the operation of an engine. The carburetor is a precise mechanical device, and utilizes the kinetic energy of the sucked air flow to realize the atomization of gasoline so as to ensure the normal operation of the machine. The carburetor can automatically match corresponding concentration according to different working state requirements of the engine and output corresponding amount of mixed gas, and in order to enable the mixed gas to be uniformly mixed, the carburetor also has the effect of atomizing fuel oil so as to enable a machine to normally run. In the existing carburetor, oil needles are fixedly arranged on a plunger, and the positions of the oil needles relative to the plunger cannot be adjusted.
Disclosure of Invention
The invention aims to overcome the defects and provides a plunger oil needle matching structure of a carburetor.
According to the scheme adopted by the invention for solving the technical problem, the carburetor plunger oil needle matching structure comprises a plunger and an oil needle, wherein a through hole is formed in the middle of the plunger, the through hole is partitioned by a diaphragm plate, a sleeve is vertically arranged in the middle of the upper side face of the diaphragm plate, an internal thread is formed in the inner wall of the sleeve, a channel hole through which the lower end of the oil needle penetrates is formed in the middle of the diaphragm plate, the oil needle is positioned in the sleeve, the lower end of the oil needle extends out of the channel hole, a spring is sleeved on the oil needle, the lower end of the spring abuts against the diaphragm plate, the upper end of the spring abuts against the oil needle, a pressing block is arranged above the oil needle in the.
Furthermore, a straight groove is formed in the middle of the upper surface of the pressing block.
Furthermore, the upper end of the oil needle is provided with a limit stop, and the upper end of the oil needle abuts against the limit stop.
Furthermore, the limit stop is integrated with the oil needle.
Furthermore, the sleeve is internally screwed with the diaphragm plate or is integrally manufactured.
Further, the diaphragm is integrated with the plunger.
Compared with the prior art, the invention has the following beneficial effects: simple structure, reasonable in design can move the regulation relatively to the plunger axial of oil needle, and it is convenient to adjust.
