Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint spraying equipment technology, and in particular to an atomizing nozzle for spraying exterior wall paint. Background Technology
[0002] Atomizing nozzles for paint spraying are an important component of spray guns. When spraying paint onto exterior walls using a spray gun, the paint is transported to the nozzle through a pipe and sprayed out from the nozzle under pressure, forming a thin, uniform coating with strong adhesion on the wall surface.
[0003] Many paints contain solid particles such as pigments and fillers, and the nozzles of atomizing nozzles are usually quite small to achieve good atomization. However, this also results in weak anti-clogging ability. When the paint stops flowing after use, these particles are prone to depositing and accumulating near the nozzle. In addition, some paints dry quickly. If they are not cleaned in time after use, the paint left in the nozzle will dry and harden rapidly, clogging the nozzle and affecting the normal use of subsequent spraying. Utility Model Content
[0004] The purpose of this invention is to provide an atomizing nozzle for spraying exterior wall coatings, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An atomizing nozzle for spraying exterior wall paint includes a nozzle body, a connecting seat fixedly installed at one end of the nozzle body, a spray hole opened at the other end of the nozzle body, two fixing seats fixedly installed on the outside of the nozzle body, a slider movably installed in each of the two fixing seats, and a connecting shaft inserted between the two fixing seats, with a pin fixedly installed on the connecting shaft located between the two fixing seats.
[0007] As a further preferred embodiment of this utility model, a sliding groove is provided in the fixing seat, which provides conditions for the installation of the pin.
[0008] As a further preferred embodiment of this utility model, the slider is slidably installed in the slide groove, and limit blocks are fixedly installed on both sides of the slider. The limit blocks are placed on one side of the fixed seat. The slider can achieve stable horizontal radial movement in the slide groove with the help of the limit blocks on both sides, thereby providing conditions for the push and reset of the connecting shaft.
[0009] As a further preferred embodiment of this utility model, a guide rod is fixedly installed on the side of the slider opposite to the connecting shaft. The side of the guide rod away from the slider extends through the through hole in the fixed seat to the side of the fixed seat. A compression spring is fitted on the outside of the guide rod. One side of the compression spring abuts against the side of the slider, and the other side of the compression spring abuts against the side of the groove. The slider, together with the guide rod and the compression spring, can realize the automatic push and reset of the connecting shaft, so that one end of the needle is inserted into the spray hole and then automatically removed.
[0010] As a further preferred embodiment of this utility model, the connecting shaft has an L-shaped structure, and one end of the pin is fixedly mounted on the connecting shaft, which enables the pushing and rotating operation of the pin.
[0011] As a further preferred embodiment of this utility model, the end of the insert pin away from the connecting shaft is fixedly equipped with an insertion part. The insertion part is provided at one end of the insert pin, so that after the insert pin moves, the insertion part can be inserted into the positioning groove, thereby breaking up the foreign objects blocking the positioning groove, which is conducive to the subsequent high-pressure medium spraying the broken particles out of the nozzle.
[0012] As a further preferred embodiment of this utility model, a positioning groove is provided on the outer side of the nozzle body near the fixed seat, and a magnetic block is fixedly installed at the bottom of the positioning groove. The positioning groove allows the pin to be flipped and positioned on the outer side of the nozzle body when the nozzle body is used.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In this invention, a pin is rotatably mounted on the outside of the nozzle body via a fixed seat and a connecting shaft. An insertion part is provided at one end of the pin. The pin can be pulled by the connecting shaft, causing the insertion part at one end of the pin to break up the foreign objects blocking the nozzle orifice, thereby achieving convenient cleaning of the nozzle orifice. At the same time, the flip-up pin can be positioned and adsorbed in the positioning groove, so as not to affect the normal use of the nozzle body. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figures 1-5 As shown, the present invention provides an atomizing nozzle for spraying exterior wall coatings, comprising a nozzle body 1, a connecting seat 2 fixedly installed at one end of the nozzle body 1, a spray hole 3 opened at the other end of the nozzle body 1, two fixing seats 4 fixedly installed on the outside of the nozzle body 1, sliders 5 movably installed in the two fixing seats 4 respectively, and a connecting shaft 6 inserted between the two fixing seats 4, and a pin 7 fixedly installed on the connecting shaft 6 located between the two fixing seats 4.
[0023] like Figures 4-5 As shown, a groove 8 is provided inside the fixed base 4. The groove 8 provides conditions for the installation of the pin 7. The slider 5 is slidably installed in the groove 8. Limiting blocks 9 are fixedly installed on both sides of the slider 5, and the limiting blocks 9 are located on one side of the fixed base 4. The slider 5 can achieve stable horizontal radial movement in the groove 8 with the help of the limiting blocks 9 on both sides, thereby providing conditions for the push and reset of the connecting shaft 6. A guide rod 10 is fixedly installed on the side of the slider 5 away from the connecting shaft 6. The side of the guide rod 10 away from the slider 5 extends through the through hole in the fixed base 4 to one side of the fixed base 4. A compression spring 11 is fitted on the outside of the guide rod 10. One side of the compression spring 11 abuts against one side of the slider 5, and the other side of the compression spring 11 abuts against one side inside the groove 8. The slider 5, together with the guide rod 10 and the compression spring 11, can realize the automatic push and reset of the connecting shaft 6, so that one end of the pin 7 is inserted into the nozzle 3 and then automatically removed.
[0024] like Figures 1-2 , Figure 4As shown, the connecting shaft 6 has an L-shaped structure. One end of the pin 7 is fixedly installed on the connecting shaft 6, which can realize the pushing and rotating operation of the pin 7. The end of the pin 7 away from the connecting shaft 6 is fixedly installed with an insertion part 12. The insertion part 12 is provided at one end of the pin 7. After the pin 7 moves, the insertion part 12 can be inserted into the positioning groove 13, thereby breaking up the foreign objects blocking the positioning groove 13, which is conducive to the subsequent high pressure medium spraying the broken particles out of the nozzle hole 3. The positioning groove 13 is provided on the outside of the nozzle body 1 near the fixed seat 4. A magnetic block is fixedly installed at the bottom of the positioning groove 13. The positioning groove 13 can be used to flip the pin 7 and position it on the outside of the nozzle body 1.
[0025] It should be noted that this utility model is an atomizing nozzle for exterior wall paint spraying. First, the nozzle body 1 is installed on the spray gun through the connecting seat 2. During normal spraying, the pin 7 is adsorbed in the positioning groove 13, which will not affect the paint from the spray hole 3. The paint is transported to the nozzle body 1 through the equipment pipeline and sprayed evenly from the spray hole 3 under pressure to realize the exterior wall spraying operation.
[0026] When a single spraying is completed and the nozzle 3 becomes clogged, one end of the connecting shaft 6 can be manually pinched. The connecting shaft 6 drives the pin 7 to rotate around its mounting point. The end of the pin 7 away from the connecting shaft 6 has an insertion part 12 and is positioned on one side of the nozzle 3. Then, the connecting shaft 6 is manually pulled towards the connecting seat 2. As a result, the connecting shaft 6 moves within the grooves 8 of the two fixed seats 4 and pushes the slider 5 within the grooves 8 to one side. The slider 5 drives the guide rod 10 to move within the through hole of the fixed seat 4 and compresses the compression spring 11. Thus, the connecting shaft 6 drives the pin 7 to move together with the guide rod 10. The needle 7 moves step by step, causing the insertion part 12 at one end to penetrate into the nozzle 3. During this process, the insertion part 12 breaks up the foreign objects blocking the nozzle 3. Then, the broken particles can be sprayed out of the nozzle 3 through the high-pressure medium, thus cleaning the nozzle 3. After the insertion part 12 of the needle 7 is inserted into the nozzle 3, the connecting shaft 6 is released. Under the elastic force of the compression spring 11, the slider 5 drives the connecting shaft 6 to return to its original position, and the insertion part 12 at one end of the needle 7 automatically moves out of the nozzle 3. After cleaning, the needle 7 is flipped over and adsorbed into the positioning groove 13 for easy use next time.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
