Brush device for spray gun {Brush device for spray gun}

The present invention relates to a brush device for a spray gun, and more particularly, to provide a brush device that can effectively perform the painting work on the corners of the industrial field, such as shipbuilding tanks, and to provide a work convenience. will be.

When painting works in shipyards or the like, a method of spraying paint supplied at high pressure by an airless pump or the like to the nozzle of a spray gun is used.

This method is efficient in painting a large surface, it is possible to minimize the paint consumption, and can significantly reduce the fatigue of the operator compared to the work using a roller or a brush, there are a number of advantages.

However, spraying was difficult to paint the corners where the cotton meets. In other words, when spraying the corner portion, paint failure occurs due to bubbles, etc., so to date, a small roller or a brush is used as a means for painting the corner portion.

In the case of using the roller or brush, there is a inconvenience of carrying a paint bucket separately, and there is a problem that excessive work time results in deterioration of work efficiency and concern of musculoskeletal disorders.

Accordingly, the present inventors have studied and developed the present invention to solve the above-described problems, and in the present invention, the brush device which enables to effectively perform the painting work on the corners in industrial sites such as shipbuilding vessels, and provides work convenience In order to provide a technical problem of the present invention to complete the present invention.

In order to solve the problem, in the present invention, the brush device can be easily assembled to the spray gun in a one-touch manner to perform painting work using the spray gun in general, and to assemble the brush when painting the corners or the like. To work.

In the case of using the brush device for spray gun provided by the present invention, especially when painting the corners, it is possible to work immediately by attaching the brush to the spray gun after spraying work can be expected to improve the work efficiency, carry a paint bucket, etc. It is a very useful invention that can achieve more than expected effects, such as can eliminate the hassle of work and can provide work convenience.

The present invention is a brush device for use in assembling the spray gun, it is a U-shape formed facing the support on both sides when viewed from the side, in the center to form a fixing hole to assemble to the spray gun, the support projection is integral to the support The fixing member formed by bending the elastic piece formed outwardly and the cover inner hole into which the nozzle cover is inserted are formed in the center, and both sides of the supporting member and the elastic piece are formed to form a fixing hole in which the fixing protrusion is indented. One plate and a brush fixed to the plate is characterized by one.

In addition, in the brush device used in the assembly of the spray gun, the locking groove formed at the tip of the nozzle cover for protecting the nozzle of the spray gun, and made of plastic to be coupled to the locking groove in a one-touch type, the center of the nozzle cover It is characterized by consisting of a plate formed with an assembling hole for the tip is assembled, and a brush fixed to the plate.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on an accompanying drawing.

Figure 1 shows an exploded perspective view of the main portion extract of the first preferred embodiment of the present invention, Figure 2 shows an assembled state cross-sectional view of the first embodiment of the present invention.

Brush device 1 for spray gun provided in the first embodiment of the present invention is fixed to the fixing member 20 and the fixing member 20 for fixing the nozzle 11 of the spray gun 10 to the rear as shown The plate 30 is coupled to the one-touch type, and consists of a configuration including a brush 40 fixed to the plate (30).

The fixing member 20 is a U-shape formed to face the support 21 to both sides when viewed from the side, a fixing hole 22 for fixing to the spray gun 10 is formed in the center, the support 21 The fixing protrusion 24 is formed by bending the elastic piece 23 formed integrally with the outside.

The plate 30 has a cover inner hole 31 in which the nozzle cover 12 is embedded is formed at the center thereof, and both sides of the plate 30 are fixed while the support 21 and the elastic piece 23 of the fixing member 20 are inserted therein. The protrusion 24 has a configuration in which a fixing hole 32 is formed to be engaged inwardly, and the brush 40 is fixed to the front.

The brush 40 is arranged in a hairy donut shape (or track type), and directly planted on the edge of the plate 30 or separately manufactured to be fixed to the plate 30.

In the assembly of the first embodiment described above, the brush 40 is held by the hand, and the support protrusion 21 and the elastic piece 23 of the fixing member 20 are inserted into the fixing hole 32 formed in the plate 30 so that the locking projections are formed. The elastic piece 23 having the locking projection 24 formed in the fixing hole 32 of the plate 30 in a state in which the elastic member 23 is pressed in the state, and the separation of the brush 40 is pressed on both elastic pieces 23. And the support 21 may be removed.

Figure 3 shows an exploded perspective view showing the main parts extract showing a second embodiment of the present invention, Figure 4 shows a cross-sectional view of the assembled state of the second embodiment of the present invention.

The spray gun brush device 1 provided in the second embodiment of the present invention includes a locking groove 13 formed at the tip of the nozzle cover 12 that protects the nozzle 11 of the spray gun 10 as shown. The plate 30 is coupled to the locking groove 13 in a one-touch manner, and the brush 40 is fixed to the plate 30.

The plate 30 is made of plastic having elasticity, and an assembly hole 33 is formed at the center of which the tip of the nozzle cover 12 is fitted, and the brush 40 is fixed to the front.

The assembly hole 33 has a tapered induction hole 34 formed at the side where the nozzle cover 12 is assembled, and the elastic locking piece 35 is symmetrically symmetrical to be caught by the locking groove 13 on the assembly hole 33. Form.

The brush 40 is arranged in a hairy donut (or track) like the first embodiment, and directly fixed to the edge of the plate 30 or separately manufactured to the plate 30.

In the assembly of the second embodiment, the brush 40 is held by hand and the assembly hole 33 formed in the plate 30 is pressed in a state in which the nozzle cover 12 is located in front of the nozzle 40. According to the present invention, The taper guide hole 34 is formed in the assembly hole 33 so that the nozzle cover 12 is naturally guided into the assembly hole 33, and when the plate 30 is pressed, an elastic catch formed inside the assembly hole 33 is applied. After the piece 35 is bent and inserted into the catching groove 13, the original piece is restored and latched. The separation of the brush 40 is by holding the brush 40 and pulling the elastic catching piece 35 from the catching groove 13. ) Is bent and separated.
