Abstract

The utility model relates to a dust-free polishing machine, in particular to a dust-free polishing machine which is used for polishing a wall surface, a wood board, a floor board or other planes. The dust-free polishing machine comprises a circular grinding disc driven by a power, and a sealing cover, wherein the sealing cover comprises a main body part and a split part; the main body part and the split part are combined into a circle matched with the circular grinding disc along an outer tangent line of the circular grinding disc; and the split part of the sealing cover is moveably connected on the main body part. When the novel dust-free polishing machine is used for polishing an inside corner of the wall surface, the wood board or the floor board, the split part of the sealing cover which is moveably connected on the main body part is only required to be removed or staggered by a certain distance, and the main body part is tightly adhered to an inside corner line of the wall surface, the wood board or the floor board along the outer tangent line of the circular grinding disc, so that the polishing machine can directly polish an inside surface near the inside corner line, and overcome the defect that a dead corner exists when the conventional polishing machine is used for polishing the wall surface, the wood board or the floor board.

Description

A kind of new no-dust sander
Technical field
The utility model relates to a kind of dustless sander, relates in particular to a kind of isoplanar dustless sander in metope, plank or floor that is used for polishing, and belongs to the engineering goods production field.
Background technology
At present, mainly by polishing, the mode of polishing is a kind of to be artificial polishing to plane sanding processing such as metope, plank or floors, and this mode inefficiency and labor strength are big; Another kind is to polish by the sander of machinery; Sander forms dustless effect in order to seal dust, and seal closure need be set; Like publication number is the disclosed technical scheme of the disclosed Chinese patent of CN201702625U; This dustless sander includes the circular emery disc of power drive and the circular seal cover that matees with circular emery disc, but this sander has certain distance owing to the circle of mating with circular emery disc that is shaped as of seal closure between the outer rim of seal closure and the outer rim of circular emery disc; When running into metope, plank or floor inner corner trim place; Circular seal closure impels the circular emery disc in the sander can't be polished to the position of inner corner trim face near inside corner line, causes and can not directly polish to metope, plank or floor with sander comprehensively, stays " dead angle " of polishing.
Summary of the invention
The utility model technical scheme, the technical problem that a kind of new no-dust sander will solve are directly to adopt the circular emery disc of dustless sander to be polished in the inside corner line place on metope, plank or floor, eliminate the defective that adopts sander to stay " dead angle ".
In order to solve the problems of the technologies described above; A kind of new no-dust sander that the utility model provides; Include circular emery disc and seal closure that power drives (power includes power such as motor or general gasoline engines); Seal closure includes main part and branch body portion, and main part is combined into the circle of mating with circular emery disc with branch body portion tangent line outside circular emery disc, and seal closure split piecemeal activity is connected on the main part.
Adopt the new no-dust sander of present technique scheme, because seal closure includes main part and branch body portion, main part is combined into the circle of mating with circular emery disc with branch body portion tangent line outside circular emery disc; Seal closure split piecemeal activity is connected on the main part; In polishing when metope, plank or floor inner corner trim place, only need to be movably connected in seal closure branch body portion on the main part and remove or let open position, like this; The practical part of sander just includes only the circular emery disc and the seal closure main part of dynamic drive; The inside corner line place on metope, plank or floor is close at the outer tangent line place of the circular emery disc in the edge of main part, and like this, sander just can directly be polished to the position of inner corner trim face near inside corner line; Eliminated at present and polished in metope, plank or floor, stayed the defective at " dead angle " with sander.
Further; Limit in the technique scheme, the mode that seal closure branch body portion and main part flexibly connect is on the contact-making surface of described seal closure branch body portion and main part, is provided with inserting column in a minute body portion; Be provided with the jack that is connected with inserting column in main part; Form the mode that seal closure divides the flexible connection main part of the dismountable inserting column jack of body portion like this, when polishing metope, plank or floor inner corner trim place, only need will the branch body portion to remove and get final product; When not being when polishing the inner corner trim place, plug the branch body portion and get final product, neither the influence sealing is comprehensive; Can eliminate at present again and polished in metope, plank or floor with sander; Stay the defective at " dead angle ", and it is quick, simple in structure to be easy to use.
Same reason; Limit in the technique scheme; The mode that seal closure branch body portion and main part flexibly connect is to be provided with rotating shaft at the place, back of the contact-making surface of described seal closure branch body portion and main part; Divide body portion through described rotating shaft hinge on main part; Forming seal closure branch body portion like this can turn over or the mode of the flexible connection main part of side upset around described rotating shaft, when polishing metope, plank or floor inner corner trim place, only needs will the branch body portion to turn over or the side upset gets final product; When not being during at polishing inner corner trim place; The split partial switching is returned to get final product, also can reach the comprehensive of neither influence sealing, can eliminate at present again and polished in metope, plank or floor with sander; Stay the purpose of the defective at " dead angle "; The situation that further guarantees seal closure branch body portion can not throw off with the seal closure main part and cause the branch body portion to lose easily exists, and uses also convenient and swift, simple in structure equally.
In addition; Can also limit in the technique scheme; The mode that seal closure branch body portion and main part flexibly connect is the place, back at the contact-making surface of described seal closure branch body portion and main part; The branch body portion is provided with draw-in groove, and main part is provided with the card rail that is connected with draw-in groove, forms seal closure branch body portion like this through the movable mode that is connected to the flexible connection main part of card rail of draw-in groove; In polishing when metope, plank or floor inner corner trim place, only need will the branch body portion to move to position, limit or remove to get final product along card rail direction; When not being during at polishing inner corner trim place; Will the branch body portion returning original position gets final product; Also can reach the comprehensive of neither influence sealing, can eliminate at present again and polished in metope, plank or floor, stay the purpose of the defective at " dead angle " with sander; Use also convenient and swift, simple in structure equally.
For the dust that produces that guarantees better will to polish siphons away, be limited to described seal closure working face and be provided with and the opposite helicla flute of circular emery disc rotation direction.
