Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of airless spray gun nozzle, and it can be suitable for different work spraying swath requirements when spraying operation.
For solving the problems of the technologies described above, the technical solution of the utility model airless spray gun nozzle is:
Comprise cylinder nozzle carrier, end one section of cylinder nozzle carrier forms four passages of right-angled intersection, a round nozzle and an elliptical nozzles is inlaid with respectively, to make cross-distribution in 90 ° between round nozzle and elliptical nozzles in two wherein adjacent passages; Nozzle carrier connects shower nozzle guard shield by left and right snap ring; Left and right snap ring is made up of the semicircle snap ring of two panels, and one end of the semicircle snap ring of two panels is with button fastening, and the other end is fastening by snap ring cap; Semicircle rail groove is formed inside the curved portions of semicircle snap ring; Semicircle rail groove can provide guiding for the rotation of nozzle carrier; Nozzle carrier is provided with two salient points, two salient points correspond to the opening of semicircle rail groove, and insert shower nozzle guard shield.
Described round nozzle is fixedly connected with the access bore of nozzle carrier respectively by nozzle pad, nozzle mold insert with elliptical nozzles
The other end of described nozzle carrier is provided with cross handle, is beneficial to the rotation of nozzle carrier relative to left and right snap ring.
Described cross handle is provided with the shape corresponding to round nozzle and elliptical nozzles, is understood the state of nozzle by the shape on cross handle.
Described cylinder nozzle carrier is refined by stainless steel and forms.
Described round nozzle and elliptical nozzles adopt wearable hard alloy to make.
The technique effect that the utility model can reach is:
The utility model can either spray circle and elliptical graphic, can realize again, from the function of clear type nozzle, being washed out by the tamper on nozzle.
The utility model is integrated with round nozzle, elliptical nozzles, nozzle from clear type nozzle three types, and pass through the guide effect of left and right first circular rail groove of snap ring, use during different graphic spraying swath need not change nozzle at needs, spraying swath nozzle half-twist just can need only wanted, rotate 180 ° and can realize recoil from clear, handled easily, simple and practical.

Detailed description of the invention
As shown in Figure 4, the utility model airless spray gun nozzle, comprise cylinder nozzle carrier 1, end one section of cylinder nozzle carrier 1 forms four passages a, b, c, d of right-angled intersection, a round nozzle and an elliptical nozzles 2 is inlaid with respectively, to make cross-distribution in 90 ° between round nozzle and elliptical nozzles in wherein adjacent two passages a, b;
Round nozzle is fixedly connected with the access bore of nozzle carrier 1 respectively by nozzle pad 21, nozzle mold insert 22 with elliptical nozzles 2;
Nozzle carrier 1 connects shower nozzle guard shield 3 by left and right snap ring 4; Left and right snap ring 4 is made up of the semicircle snap ring of two panels, and one end of the semicircle snap ring of two panels is with button fastening, and the other end is fastening by snap ring cap 41; The semicircle snap ring of two panels is fixed on shower nozzle guard shield 3; Semicircle rail groove is formed inside the curved portions of semicircle snap ring; Semicircle rail groove can provide guiding for the rotation of nozzle carrier 1, is led by left and right snap ring 4 when nozzle carrier 1 enters shower nozzle guard shield 3; Nozzle carrier 1 is provided with two salient points, two salient points correspond to the opening of semicircle rail groove, and insert shower nozzle guard shield 3;
The other end of nozzle carrier 1 is provided with cross handle, is beneficial to the rotation of nozzle carrier 1 relative to left and right snap ring; Cross handle is provided with the shape corresponding to round nozzle and elliptical nozzles, is understood the state of nozzle by the shape on cross handle.
Cylinder nozzle carrier 1 is refined by high-quality stainless steel and forms, and sealing property is good, with the coating of applicable different medium.
Because round nozzle and elliptical nozzles very easily wear and tear, once nozzle bore becomes large, film super thick and uneven, not only increases paint consumption, but also paint vehicle can be made to be difficult to drying, affect manufacturing schedule; As bad in nozzle material and cause wearing and tearing, spray orifice becomes large and justifies, and ejection coating is fan-shaped and diminish, and flow increases, and has a strong impact on presentation quality and the thickness quality of paint film, therefore nozzle material quality to the service life of nozzle and spraying swath quality most important.Round nozzle of the present utility model and elliptical nozzles adopt wearable hard alloy to make, and are applicable to the spraying of high viscosity, high density and zinc-rich paint, can improve service life.
Operation principle of the present utility model is as follows:
As shown in Figure 5 a to 5 c, when round nozzle upwards time, nozzle sprays circular spraying swath; Make nozzle carrier 1 rotate 180 °, now round nozzle is downward, as shown in Fig. 7 a to Fig. 7 c, can wash out the tamper on round nozzle, reach the object of self-cleaning;
Make nozzle carrier 1 half-twist, now elliptical nozzles upwards, as shown in Fig. 6 a to Fig. 6 c, can change oval spraying swath into from circular spraying swath; Make nozzle carrier 1 rotate 180 ° again, now elliptical nozzles is downward, as shown in Fig. 8 a to Fig. 8 c, can wash out the tamper on elliptical nozzles, reach the object of self-cleaning.
