Problems solved by technology

[0002] The existing plane sandpaper grinding frame can basically not grind horizontally. When grinding horizontally, the sandpaper frame will jump up and cannot move smoothly, and can only be polished vertically or obliquely. More than 50% of the contact area with the wall requires more working time to smooth the wall; the existing sandpaper holders are generally short in length, and if they are lengthened, they are easy to deform and the loss outweighs the gain; the sanding work is affected by the movement of hands The width is limited and the grinding area is small; the existing flat corner sandpaper holder, the free end of the wide surface is easily deformed longitudinally, and the sandpaper holder needs to be turned around when grinding the corner, which is not very convenient. The wall cannot be polished smoothly or horizontally, and the sandpaper at the outer corners is easy to wear, which is a waste of sandpaper

Embodiment 1

[0035] Such as figure 1 , Figure 7 As shown, when grinding the wall surface, select the appropriate type of self-adhesive sandpaper or emery cloth and paste it with the hook surface velcro cloth 02, and then attach the emery cloth surface to the wall or corner, within the range of human body height, the worker can hold it with one hand Handle 03 for grinding, or connect the handle 03 with the round hole 035 and then connect the extension rod or telescopic handle 08, the worker holds the extension rod or telescopic handle 08 to polish the wall, and can open it when the indoor light is insufficient Lighting lamp 082 carries out precise grinding on the wall surface. When finely grinding the bottom putty of fluorocarbon paint, it can firstly use the connecting elastic sheet sandpaper frame to carry out fine grinding without trace. 01 can move smoothly horizontally without jumping and flipping, which greatly improves the polishing progress and the flatness of the wall.

Embodiment 2

[0037] Such as figure 2 As shown in -7, the back of the frame body 01 is provided with a universal joint 04 and then connected to an extension rod or a telescopic handle 08, and the worker can hold the extension rod or the telescopic handle 08 to move the wall up and down or left and right Or arc-type mobile grinding, the structural device of the present invention greatly improves the grinding progress, reduces the physical exertion of workers, reduces the dependence on the use of scaffolding, and increases the construction safety; For quick adjustment of knuckle flexibility, there may be a round hole in the middle of the frame body 01 and hook surface Velcro 02, which can be used for screwdriver or hexagon pickpocket to tighten the screw plug after passing through the round hole.

Embodiment 3

[0039] Such as figure 1 As shown in -7, when the device of the present invention grinds the inner corner of the wall, the frame body 01 can be flexible and smooth without turning around and just can polish the left wall or the right wall of the corner. The support setting on the side and the strength of the frame are effectively improved, and the service life of the sandpaper at the corner is doubled, which can maintain the simultaneous loss of the sandpaper or abrasive cloth on the plane and the sandpaper or abrasive cloth on the corner, thereby increasing the use time of the sandpaper. Reduced construction costs.

Abstract

The invention provides a universal self-adhesive three-sided double-angle internal and external corner sandpaper frame, and relates to the field of wall putty polishing construction, and comprises a concave or right-angle U-shaped frame body, a right-angle aluminum alloy frame body, an elastic sheet sandpaper frame, a hook surface hook and loop fastener cloth, a handle, a universal joint, a lengthened rod or a telescopic handle rod. The two three-sided double-angle sides can make the strength of the frame body be strengthened without deformation due to use, the frame body can be lengthened, the grinding surface is widen, thickening in the middle of the back makes the grip connection be strong and durable, double-angle setting can prolong the use time of sandpaper and reduce the cost, due to the use of the elastic sheet sandpaper frame, the grinding connecting part is in seamless connection, and the application of the universal joint, the lengthened rod or the telescopic handle rod canreduce the technical requirements on workers, increase the moving distance of the frame body, make the frame body not jump when moving transversely, can accurately grind the wall surface, and increasethe construction speed and safety.

Description

technical field [0001] The invention relates to the field of wall putty grinding construction, in particular to a universal self-adhesive sandpaper stand with three sides, double corners, yin and yang corners. Background technique [0002] The existing flat sandpaper grinding frame can basically not grind horizontally. When grinding horizontally, the sandpaper frame will take off and cannot move smoothly, and can only be polished vertically or obliquely. More than 50% of the contact area with the wall requires more working time to smooth the wall; the existing sandpaper holders are generally short in length, and if they are lengthened, they are easy to deform and the loss outweighs the gain; the movement of the hand is affected by the sanding work The amplitude is limited and the grinding area is small; the existing flat corner sandpaper holder, the free end of the wide surface is easily deformed longitudinally, and the sandpaper holder needs to be turned around when grindin...
