Description

A kind of nozzle of spray gun for paint

Technical field

The utility model relates to lance technology fields, and in particular to a kind of nozzle of spray gun for paint.

Background technique

Spray gun for paint is a kind of pneumatic tool for spray painting.In order to control the spraying swath size of coating, in spray gun for paint usually It can be improved on air flue.The air-flow of spray gun for paint divides two-way by the air flue of gun body, passes through the gas of 4 ∮ 2.5mm of nozzle facade all the way Hole is discharged from the centre bore of spray head and plane hole, and another way is by the stomata of the 4 ∮ 2.6mm in nozzle side from two goat's horn hole of spray head Discharge.Wherein the stomata of ∮ 2.5mm mainly has the function of controlling spraying overlap, flash, therefore the gas cell distribution situation of ∮ 2.5mm Directly affect spraying flash；The stomata of ∮ 2.6mm mainly has the function of atomised coating behind spraying swath goat's horn hole, it is directly affected Atomizing particle, distributing position influence the size and stabilization of atomization air flow.But existing nozzle its air-flow can be distributed not because of hole site It uniformly changes, there is the problems such as uneven by spraying, atomizing effect is poor.Furthermore existing nozzle does not conform to since stomata is laid out Reason, causes the mechanical strength of nozzle poor, is easily damaged.

Summary of the invention

Therefore, for above-mentioned problem, the utility model proposes a kind of new type nozzles of spray gun for paint, it is therefore intended that solves existing There is the above problem existing for nozzle.

The technical solution adopted in the utility model is as follows:

A kind of nozzle of spray gun for paint, including tube body, the upper end of the tube body are equipped with nozzle head, and lower end, which is equipped with, to be used for and spray gun for paint The external screw thread being connected, the outer wall of above-mentioned tubular body is alternatively arranged along its axial direction is provided with first annular recess portion, the second annular Recess portion and third annular recess, and the outer wall of tube body forms a ring body in first annular recess portion and the second annular recess；It is above-mentioned The upper surface of tube body is set around nozzle head there are six the first stomata for being in arranged in regular hexagon shape, and above-mentioned first stomata is another End axially extends to third annular recess along tube body, and above-mentioned ring body sets that there are six for being connected to first annular recess portion and second annular Recess portion and be in arranged in regular hexagon shape the second stomata.

Further, projection of first stomata with the second stomata along tube body axial direction mutually staggers.

Further, the tube wall at above-mentioned first annular recess portion and the second annular recess position is in regular hexagonal prism shape Shape, through regular hexagonal prism corner location, above-mentioned second stomata is located on the outside of the sideline of regular hexagonal prism above-mentioned first stomata.

Further, the diameter of above-mentioned first stomata is 2.0mm；The diameter of above-mentioned second stomata is 2.3mm.

Further, above-mentioned second stomata is obliquely installed towards the axle center of above-mentioned tubular body from top to bottom.

Further, said nozzle head includes up-small and down-big conical tube, and the upper end of the conical tube is equipped with cylindrical tube Body, lower end are docked with the sealing of the upper end of above-mentioned tubular body.

It is compared with existing technology, utility model has the advantages that

One, the utility model include tube body, and tube body is provided with first annular recess portion, the second annular recess and third annular Recess portion, and a ring body is formed in first annular recess portion and the second annular recess；Above-mentioned tubular body is in arranged in regular hexagon shape there are six setting The first stomata, ring body set there are six be in arranged in regular hexagon shape the second stomata.Wherein the first stomata is used for the plane with spray cap Hole is connected, and the second stomata is used to be connected with the goat's horn hole of spray cap.By the layout again to the first stomata and the second stomata, It allows the more rationally uniform distribution setting of these stomatas, allows and reach the speed of the air-flow of spray cap faster, it is more stable.

Secondly, in the utility model, the diameter of the first stomata is 2.0mm；The diameter of above-mentioned second stomata is 2.3mm.Phase Than in existing nozzle, since the diameter of the first stomata becomes smaller, air-flow is just more anxious in the case that face air pressure is constant, flow velocity faster, is inhaled The pressure of paint is just bigger, and the diameter of the second stomata becomes smaller, and atomization air flow becomes larger in the case that air pressure is constant, and the atomization of coating is just It is finer and smoother.

Thirdly, in the utility model, projection of first stomata with the second stomata along tube body axial direction mutually staggers.First stomata It is mutually staggered with the second stomata, the air-flow of spray gun for paint air flue can be allowed more uniform, more smoothly flow into the first stomata and Two stomatas guarantee that the air-flow of each stomata is more steady, are conducive to improve final spray painting effect.In addition, first annular recess portion and Tube wall at second annular recess position is in regular hexagonal prism shape, above-mentioned first stomata through regular hexagonal prism corner position It sets, above-mentioned second stomata is located on the outside of the sideline of regular hexagonal prism.Tube body at first annular recess portion and the second annular recess position Outer wall is in regular hexagonal prism shape, and the first stomata is run through and is arranged in regular hexagonal prism corner location, it is ensured that nozzle Mechanical strength.
