At present, the engine working process generates vibration, a high-pressure oil inlet of an oil sprayer is connected with a high-pressure oil pipe, so that the high-pressure oil inlet of the oil sprayer is stressed, the positioning part of the oil sprayer receives larger force, the main positioning is performed on the cap tightening part and the positioning frame, long-time vibration is performed, the cap tightening part of the oil sprayer is easy to abrade, dust easily enters the hole, and meanwhile a plurality of oil sprayers are fixed on one positioning frame and are not convenient to detach and overhaul.
The above background disclosure is only provided to aid understanding of the inventive concepts and solutions of the present invention, and it does not necessarily pertain to the prior art of this patent application, and it should not be used to assess the novelty and inventive aspects of this application without explicit evidence that such contents are disclosed at the filing date of this patent application.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a location structure's sprayer solves the long-time vibrations of present sprayer, leads to the tight cap of sprayer to have wearing and tearing easily, and the dust easily gets into downtheholely, and a plurality of sprayers are fixed on a locating rack problem of the dismantlement maintenance of being not convenient for simultaneously.
In order to realize the purpose, the utility model adopts the following technical proposal:
a kind of oil atomizer of the positioning structure, characterized by: the fuel injector comprises a nozzle, a tightening cap and an injector body, wherein the nozzle is arranged in the center of the bottom of the tightening cap, and the top of the tightening cap is connected with the bottom of the injector body; the lower part of the tightening cap is provided with a first positioning end, the middle part of the oil injector body is provided with an O-shaped ring groove, and the lower part of the O-shaped ring groove is provided with a second positioning end; two symmetrical bayonets are arranged on two sides of the upper part of the O-shaped ring groove; the top of the oil injector body is provided with a high-pressure oil inlet hole, and an oil return hole and a wiring harness plug-in terminal are respectively arranged below the high-pressure oil inlet hole.
Furthermore, the top of the tightening cap is connected with the bottom of the oil injector body in a threaded screw hole mode.
Furthermore, a hexagonal nut body is arranged at the lower part of the first positioning end.
Furthermore, an O-shaped ring is arranged on the O-shaped ring groove.
The utility model has the advantages of compared with the prior art:
1. the utility model discloses mainly constitute by nozzle, tight cap and injector body, be equipped with the mounting hole lower part on tight cap that first location end and the cylinder cap cooperate and realize injector location installation, still be equipped with the second location end on the injector body simultaneously and cooperate with the realization dual location with the mounting hole upper portion on O type circle and the cylinder cap, the oblique installation of cutting during preventing the assembly leads to injector slope to influence engine work with the vibrations of engine operation process.
2. The utility model discloses an injector body both sides are equipped with two symmetrical bayonets, compress tightly the location alone with the sprayer through chucking piece and bayonet socket cooperation, can prevent that the sprayer is not hard up and slope.
3. The utility model has the advantages of compact structure, multi-point positioning, convenient installation and good sealing performance.
