Abstract

A movable spray-painting stand includes a worktable provided with four casters and having a wind-exhausting device and a filtering device assembled thereon. The wind-exhausting device has an air inlet communicating with the wind outlet of the filtering device. A separating device is provided in front of the wind inlet of the filtering device to form a spray painting space. A collapsible work frame is pivotally assembled with the work table and positioned under the separating device, able to be positioned in the spray painting space after articles to be spray painted are placed on its upper plate. The spray painting stand can be moved around freely, and the exhaust and the odor of paint produced during spray painting can be filtered by the filtering device, conforming to environmental protection and ensuring workers'"'"' health.

Claims

1. A movable spray-painting stand comprising:

A work table provided with four legs under its table top, said four legs having their lower ends respectively assembled with a caster;

A wind-exhausting device assembled on said table top of said work table, said wind-exhausting device composed of a motor, a cover and a blade wheel, said blade wheel fitted on a rotating shaft at the front end of said motor to be driven to rotate, said cover covered around said blade wheel and having its front side bored with an air inlet and its topside bored with an air outlet;

A wind-power indicator comprising a supporting member, a swing member, an indicating faceplate and an index hand, said supporting member assembled inside said cover of said wind-exhausting device, said supporting member positioned near said air outlet of wind-exhausting device, said swing member having one end pivotally positioned on the intermediate portion of said supporting member, said swing member having the other end pivotally inserted out of the opposed wall of said cover, said swing member having its intermediate portion provided with a wind-actuated rod extending outward vertically, said wind-actuated rod positioned at the air exhausting passageway of said air outlet of said wind-exhausting device, said indicating faceplate assembled on the outer wall of said cover, which said swing member is inserted there-through, said index hand fixed at the outer end of said swing member, said index hand able to swing on said indicating faceplate together with the rotation of said swing member, a wind exhausting power able to be judged according to a spot where said index hand indicates on said indicating faceplate;

A filtering device composed of a machine housing, a first filtering plate and a second filtering plate, said machine housing assembled on said table top of said work table, said machine housing having its front end formed with an wind inlet and its rear end formed with a wind outlet, said wind outlet of said machine housing communicating with said air inlet of said cover of said wind-exhausting device, said first filtering plate assembled at the location of said wind inlet of said machine housing, said second filtering plate assembled at a location near the intermediate portion of said machine housing;

A separating device composed of an upper blocking plate and two side blocking plates, said upper blocking plate assembled on the topside of said machine housing of said filtering device and positioned above said wind inlet, said two side blocking plates respectively assembled at the opposite sides of said wind inlet of said machine housing, said two side blocking plates having their upper edges respectively connected with said upper blocking plate, said upper blocking plate and said two side blocking plate connected with one another to form a spray painting space; and

A work frame composed of plural feet and an upper plate positioned on said feet, said feet able to be collapsed and laid under said stand, said upper plate used for placing articles to be spray painted, said upper plate having its inner end pivotally assembled with two opposed legs of said work table, said stand able to be pivotally turned inward and collapsed.

2. The movable spray painting stand as claimed in claim 1, wherein said second filtering plate is positioned in a cut groove bored at the upper side of the intermediate portion of said machine housing, able to be pulled out of said cut groove.

3. The movable spray painting stand as claimed in claim 1, wherein the rear half portion of said filtering device is rectangular-shaped and the front half portion is trumpet-shaped so as to increase an air-sucking area and enlarge a spray painting space.

4. The movable spray painting stand as claimed in claim 1, wherein said first and said second filtering plate of said filtering device are made of active carbon screen and non-woven fabric.

5. The movable spray painting stand as claimed in claim 1, wherein said upper blocking plate and said two side blocking plates are respectively provided with a frame attached thereon with a cloth screen.

6. The movable spray painting stand as claimed in claim 1, wherein said two side blocking plates of said separating device have their outer lower ends respectively fixed with an elastic insert member, and said upper plate of said work frame has the outer ends of its opposite sides respectively bored with a positioning hole so that said two side blocking plates can be stabilized on said upper plate by respectively inserting said elastic insert members into said positioning holes of said upper plate.
