Description

A kind of sand frame of novel suitable polishing inner corner trim

Technical field

The utility model relates to the polisher on wall face in building decoration field, especially a kind of novel suitable polishing inner corner trim Sand frame.

Background technique

In building decoration construction, the polishing of metope is essential working procedure, is metope of being polished with sand frame in the past, Now with the progress of science and technology, people start to improve work efficiency, still generally using disc type wall grinding machine come metope of polishing What handwork still had, the smooth place of large area because wall grinding machine can only polish, at those narrow places and inner corner trim, Still need to polish by sand frame, be usually on the clamping plate of traditional sand frame burning into sand paper side install a torque spring and The iron sheet of iron clamp piece is again thin, and intensity is inadequate, is easily deformed for a long time using iron clamp piece, and sand paper just presss from both sides insecure, is using Cheng Zhong, sand paper are easy displacement, and worker needs the compactness of often correction sand paper and sand frame bottom plate, brings inconvenience to construction； What is pasted on traditional sand frame bottom plate is common elastic sponge layer, is used for a long time, and the corner angle on four sides are easy to be extruded abrasion At fillet, it will appear when such sand frame polishing inner corner trim that compactness is poor, the bad situation of grinding effect.

Summary of the invention

The purpose of this utility model is to provide for a kind of sand frame of novel suitable polishing inner corner trim.

In order to achieve the above objectives, the utility model is implemented according to following technical scheme:

A kind of sand frame of novel suitable polishing inner corner trim, including rectangular recess pedestal and the handle being set on rectangular recess pedestal Hand, the bottom of the rectangular recess pedestal are fixed with hard foam layer, are enclosed in the bottom and side wall of the hard foam layer Elastomeric skin layer, the both ends interior of the rectangular recess pedestal are respectively equipped with sand paper clamping plate, and the bottom of the sand paper clamping plate is solid It is scheduled on rectangular recess pedestal, the upper end of the sand paper clamping plate is zigzag and pastes with the interior of the rectangular recess pedestal It closes, is fixed by screws between the inner wall of the sand paper clamping plate and the rectangular recess pedestal there are two sand paper clamping plate can be made The middle part of the L-type spring leaf of clamp rectangular groove base side wall, the sand paper clamping plate is connected with pressing hand by connecting shaft Handle.

Further, the side of the rectangular recess pedestal is equipped with red warning labeling.

Further, the L-type spring leaf include L-type elastic plate and be set to L-type elastic force board ends fixation upper plate and Fixed lower plate.

Further, the fixed upper plate is fixed by screws on the inner wall of the clamping plate, and the fixed lower plate passes through Screw is fixed on the rectangular recess pedestal.

Further, there is drawer-like sand in the bottom of the rectangular recess pedestal by L-type spring leaf and sand paper Boards wall Paper, the drawer-like sand paper do not have mortar crust on the side outer wall far from the red warning labeling.

Compared with prior art, the sand frame of the novel suitable polishing inner corner trim of the utility model is compared with traditional sand frame, is adopted With rectangular recess pedestal, mating installation drawer-like sand paper is wrapped in four sides of sand frame pedestal also by sand paper, corner of polishing When, it is not in the case where fast side of sand paper scratches metope, the pedestal side of the utility model is equipped with red warning labeling, described Sand paper does not have mortar crust on the side wall far from red warning labeling, and design is pasted with red to remind staff in this way There is mortar crust on the side wall of color warning labeling, should be noted that when polishing paintless door set or switch enclosure with no sand One end fitting paintless door set or switch enclosure of crust are starched, in order to avoid damage.

Traditional sand frame usually using single torque spring strap, for a long time using will appear clamping plate offset, sand Paper fixes the case where out-of-flatness, and the clamping plate of the utility model generates elastic force by two L-type spring leafs to be tensioned clamping plate, and structure is steady Gu be unlikely to deform, for a long time using being not in sand paper sideslip the phenomenon that, in addition traditional sand frame use the conduct of hard foam layer Bottom, in use process, four corner angle of hard foam layer can be worn, polish inner corner trim when poor, the grinding effect that will appear compactness Bad situation, the utility model are wrapped in the bottom and side wall of hard foam layer using elastomeric skin layer, reinforce the strong of corner angle Degree, corner angle are not damaged, polish inner corner trim when compactness it is high, grinding effect is good, improves work task efficiency.
