Description

A kind of spray gun for paint needle mouth

Technical field

The utility model relates to spray gun fittings technical fields, more particularly, to a kind of spray gun for paint needle mouth.

Background technique

Spray gun is the tool by the way that material spray to be sprayed to tool face under a certain pressure, and spray gun includes being arranged in the body of a gun Needle mouth and rifle needle shock is constantly generated between rifle needle and needle mouth, therefore the syringe needle of rifle needle is very due in the spray gun course of work It is prone to wear, since syringe needle abrasion will lead between rifle needle and needle mouth, contact surface is bad, causes to leak, and as contained by material spray Some ingredients have part to will lead to the corrosion of rifle needle, and therefore, it is necessary to irregular replacement rifle needles；In spraying process, coating is from spray A forward active force can be generated to nozzle by spraying in mouth, and nozzle is easy to loosen or fall, and influence coating quality.

Utility model content

The utility model is to overcome above situation insufficient, it is desirable to provide a kind of technical solution that can solve the above problem.

A kind of spray gun for paint needle mouth, including rifle needle and needle mouth, the rifle needle is by the cylindrical needle body and is set to cylindrical needle body end The conical syringe needle in portion forms, and conical syringe needle uses polyoxymethylene material；Needle mouth end is equipped with pin hole, the pin hole Diameter be equal to the diameter of the cylindrical needle body, needle mouth front end is then equipped with bellmouth, the pin hole and taper The channel for installing rifle needle is equipped between hole；The tail portion of the cylinder needle body is cased with limiting device；The outer wall in the channel It is cased with washer, the washer is made up of polypropylene.

Preferably, the round and smooth processing in tip of the conical syringe needle.

Preferably, the end of the cylindrical needle body has integrally formed tapered joint head, and the cone syringe needle is It is directly molded on the hollow cone of connector.

Preferably, the conical syringe needle is the solid cone for being directly molded on cylindrical needle body end.

Compared with prior art, the utility model has the beneficial effects that conical syringe needle uses polyoxymethylene material, make Rifle needle is more wear resistant, is hardly damaged, and the outer wall in channel is cased with washer, not only makes the more preferable of each component cooperation, but also into one Step enhances the wearability and corrosion resistance of rifle needle, extends the service life of rifle needle.

The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description In become obvious, or recognized by the practice of the utility model.

Specific embodiment

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Please refer to Fig. 1~4, in the utility model embodiment, a kind of spray gun for paint needle mouth, including rifle needle and needle mouth 6, the rifle Needle is made of the cylindrical needle body 2 with the conical syringe needle 1 for being set to 2 end of the cylindrical needle body, and conical syringe needle 1 uses polyoxy methylene Sill；6 end of needle mouth is equipped with pin hole 8, and the diameter of the pin hole 8 is equal to the diameter of the cylindrical needle body 2, 6 front end of needle mouth is then equipped with bellmouth 4, and the channel 7 for installing rifle needle is equipped between the pin hole 8 and bellmouth 4；It is described The tail portion of the cylindrical needle body 2 is cased with limiting device 3；The outer wall in the channel 7 is cased with washer 5, and the washer 5 is by polypropylene system At.

The round and smooth processing in tip of the cone syringe needle 1.

The end of the cylinder needle body 2 has integrally formed tapered joint head 9, and the cone syringe needle 1 is direct Take shape in the hollow cone of connector 9.

The cone syringe needle 1 is the solid cone for being directly molded on cylindrical 2 end of the needle body.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
