Abstract
The utility model belongs to spray gun fittings technical field, more particularly to a kind of wear-resisting rifle pin of spray gun for paint, including rifle pin body, rifle pin includes being coated with wearing layer respectively on the conical syringe needle and the cylindrical needle body of integral type, the outer surface of the outer surface of syringe needle, the outer surface for the forward end of needle body being connected with syringe needle or the whole needle body；The utility model has the advantage that：One layer of ceramic layer or titanium plated alloy layer are sprayed in the outer surface of rifle pin, the wearability of rifle pin is improved, reduces the abrasion of rifle pin and nozzle, the service life of rifle pin can be extended.
Description
Technical field
The utility model belongs to spray gun fittings technical field, more particularly to a kind of spray gun for paint wear-resisting rifle pin.
Background technology
Spray gun is generally by the instrument that material spray is sprayed to tool face under a certain pressure, and spray gun includes being arranged on rifle
Body inner nozzle and rifle pin, due to producing shock between the need of work rifle pin and rifle mouth of spray gun, therefore the head of rifle pin holds very much
Easily wear and tear, cause the contact surface of rifle pin and nozzle bad, cause leakage.At present, most spray gun is all used on the market
Stainless steel material is as rifle pin, although the rifle pin manufacturing cost of this material is low, easy to wear, service life is low, therefore market
On also occur in that whole rifle pin is made of ceramic material, but the rifle pin being made of ceramic material, although solve rifle
The problem of pin is easy to wear, but cost is high, the very big overall cost for improving spray gun.
Utility model content
The purpose of this utility model is to provide a kind of wear-resisting rifle pin of spray gun for paint.
What the purpose of this utility model was realized in：
A kind of wear-resisting rifle pin of spray gun for paint, including rifle pin body, rifle pin include the conical syringe needle and cylinder of integral type
Sprayed respectively on the needle body, the outer surface of the outer surface of syringe needle, the outer surface for the forward end of needle body being connected with syringe needle or the whole needle body
There is wearing layer.
The axial length of the wearing layer of the outer surface for the leading section that the above-mentioned needle body is connected with syringe needle accounts for needle body axial overall length
1/3rd.
The above-mentioned tip rounding off for stating conical syringe needle.
The tail end necking down of the above-mentioned cylindrical needle body forms the afterbody of the frusto-conical bodily form.
Above-mentioned wearing layer is ceramic layer or titanium plated alloy layer.
The thickness of above-mentioned wearing layer is 0.1mm-0.5mm.
The thickness of above-mentioned wearing layer is 0.2mm.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1st, the utility model sprays one layer of ceramic layer or titanium plated alloy layer in the outer surface of rifle pin, improves the wear-resisting of rifle pin
Property, reduce the abrasion of rifle pin and nozzle, the service life of rifle pin can be extended.
2nd, the manufacturing cost of the utility model rifle pin is low, effectively reduces the overall cost of spray gun.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is use state schematic diagram of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-3：
A kind of wear-resisting rifle pin 1 of spray gun for paint, including the body of rifle pin 1, rifle pin 1 include the conical syringe needle 2 and circle of integral type
The cylindricality needle body 3, the tip of conical syringe needle 2 is spherical end, and the tail end necking down of the cylindrical needle body 3 forms the frusto-conical bodily form
Afterbody 5, the outer surface of syringe needle 2, the outer surface for the leading section of the needle body 3 being connected with syringe needle 2 are coated with wearing layer 4, the axle of wearing layer 4
Accounted for length on 1/3rd of the axial overall length of the needle body 3, or the outer surface of the whole needle body 3 and be coated with wearing layer 4, wearing layer 4
For ceramic layer or titanium plated alloy layer, the utility model Ceramics layer as wearing layer 4；The thickness of wearing layer 4 is 0.1mm-
0.5mm, the specific thickness of wearing layer 4 of the present utility model is 0.2mm.
The diameter for the outer end that the diameter of above-mentioned needle body afterbody 5 and the abutting end of the needle body 3 is more than, and needle body afterbody 5 and the needle body 3
The diameter of abutting end is equal
The inner face top of the utility model bellmouth 11 of the conical pipette tips outer surface of rifle pin 1 and nozzle 10 when in use
Connect, therefore the spraying abrasion-proof layer 4 in the outer surface of syringe needle 2 can effectively reduce the abrasion of rifle pin 1 and nozzle 10, extension rifle pin 1
Service life
Above-described embodiment is only preferred embodiment of the present utility model, and protection model of the present utility model is not limited according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
Within the scope of.
