Abstract

This invention discloses a wall polisher for building decoration of this invention, comprising a main body, a housing fixedly arranged on one end of the main body, a slot with an opening towards one end disposed in the housing, a handle fixedly set on the top end face of the main body, standing bases up and down symmetrically disposed on one end face of the main body, a pushing cushion which is fixedly connected to one end face of the main body arranged between the two standing bases; wherein the housing is attached on the rough wall surface with the handle held and the push force applied to the pushing cushion; a dust collecting device which is dismountable disposed on the bottom of the housing; wherein the dust produced during polishing is collected by the dust collecting device, which prevents the dust from spreading to pollute the environment.

Claims

1. A wall polisher for building decoration of this invention, comprising:

a main body,

a housing fixedly arranged on one end of said main body,

a slot with an opening towards one end disposed in said housing,

a handle fixedly set on a top end face of said main body,

standing bases up and down symmetrically disposed on one end face of said main body,

a pushing cushion which is fixedly connected to one end face of said main body arranged between two said standing bases;

a dust collecting device which is dismountable disposed on a bottom of said housing,

a hanging slot mounted on one bottom end face of said housing,

a pushing assembly which pushes said dust collecting device arranged on the bottom end face of said main body,

a polishing head arranged in said slot,

wherein a bottom end wall of said slot is provided with a tilted slot;

a drive device which is used for driving said polishing head to rotate arranged in said main body,

wherein said drive device comprises a control cavity and a through hole which is communicated between said control cavity and said slot,

a spindle rotatably mounted in said through hole through a bearing,

wherein one end of said spindle extends towards one end into said slot and is fixedly connected with said polishing head, and the other end of said spindle extends towards the other end into said control cavity and is fixedly provided with a left bevel gear;

wherein an upper end wall of said control cavity is provided with an upper sliding chute, and a lower end wall of said control cavity is provided with a lower sliding chute,

wherein one end wall of said upper sliding chute is provided with a upper transversal slot, and one end wall of said lower sliding chute is provided with a lower transversal slot;

a drive slot communicated between one end of said upper transversal slot and one end of said lower transversal slot,

an upper matching slot and a lower matching slot up and down symmetrically arranged on one end wall of said control cavity,

an upper slider which slides towards two ends arranged in said upper sliding chute,

wherein said upper transversal slot is provided with an upper transverse block which slides towards two ends, and on end of said upper transverse block is integrated with said upper slider,

wherein the other end of said upper transverse block extends towards one end into said drive slot and is integrated with an upper connection block which extends downward,

wherein a bottom end face of said upper connection block is fixedly provided with an upper rack;

a lower slider which slides towards two ends arranged in said lower sliding chute,

wherein said lower transversal slot is provided with a lower transverse block which slides towards two ends and one end of which is integrated with said lower slider,

wherein one end of said lower transverse block extends towards one end into said drive slot and is integrated with a lower connection block which extends upward, and a top end face of said lower connection block is fixedly provided with a lower rack;

a power assembly arranged between said upper rack and said lower rack as well as at the middle of said drive slot,

a rotating motor embedded in a bottom end face of said upper slider,

wherein an output shaft of said rotating motor extends downward into said control cavity and is fixedly provided with a right bevel gear which is opposite to said upper matching slot and is used for engaging with said left bevel gear;

wherein a top end face of lower slider, through a connecting rod, is fixedly provided with a fixed bevel gear which is opposite to said lower matching slot and is used for engaging with said left bevel gear;

wherein said rotating motor is controlled to operate to drive the right bevel gear to rotate to drive the left bevel gear to rotate, which drives the polishing head to rotate through a spindle, and the housing is attached on a rough wall surface with said handle held and the push force applied to said pushing cushion, and the rough wall surface is polished through the polishing head.

2. The wall polisher for building decoration according to claim 1, wherein said power assembly comprises a drive gear which is rotatably arranged through said rotating shaft and engages with said upper rack and said lower rack,

wherein said drive gear is fixedly connected to said rotating shaft,

wherein a rear end of said rotating shaft is in power connection with said drive motor which is set on the rear end wall of said drive slot, and a front end of said rotating shaft is in rotational engagement with the front end wall of said drive slot;

wherein the drive motor is controlled to operate to drive the rotating shaft to rotate, so that the drive gear is driven to rotate.

3. The wall polisher for building decoration according to claim 1, wherein said dust collecting device comprises a box body,

a collecting tank which has an upward opening and is used for being communicated with said tilted slot arranged in said box body,

wherein one side of the top end face of said box body is provided with a hanging plate, and said box body and said hanging plate are formed into a one-piece structure;

wherein one end face of said hanging plate is fixedly provided with a hanging block which is used for coupling with said hanging slot,

wherein a periphery of one end face of said hanging block is provided with a guide bevel, wherein said collecting tank is hemispherical, and the dust produced during polishing is collected by the collecting tank through the tilted slot.

4. The wall polisher for building decoration according to claim 1, wherein said pushing assembly comprises a pushing sliding chute,

a pushing sliding plate which slides towards two ends and extends downward mounted in said pushing sliding chute,

a grab handle fixedly disposed on one end face of said pushing sliding plate,

a pushing spring slot arranged on one end wall of said pushing sliding chute,

wherein said pushing sliding chute is provided with a guide rod which extends towards two ends and penetrates through said pushing sliding plate and is in sliding fit connection with said pushing sliding plate,

wherein one end of said guide rod is fixedly connected with one end wall of said pushing sliding chute, and the other end of said guide rod is fixedly connected with the other end wall of said pushing sliding chute;

a pushing spring which is used for pushing said pushing sliding plate towards one side wound around said guide rod,

wherein one end of said pushing spring is fixedly connected to one end face of said pushing sliding plate, and the other end of said pushing spring is fixedly connected to one end wall of said pushing spring slot;

wherein the pushing sliding plate is pulled towards one side through a grab handle, and then said hanging block is inserted into said hanging slot and couples with the said hanging slot, which makes the top end face of the box body touch against the bottom end face of the housing, thereby making the collecting tank communicated with the tilted slot, and then, through releasing the grab handle, the pushing sliding plate pushes the hanging plate under the elastic force of the pushing spring, which locks the position where the box body is.

5. The wall polisher for building decoration according to claim 1, wherein respective volumes of said left bevel gear, right bevel gear and fixed bevel gear are the same, and one end face of said polishing head is in the same plane as one end face of said housing.

6. The wall polisher for building decoration according to claim 1, wherein

said upper connection block, said upper slider and said upper transverse block are formed into a one-piece structure, and said lower connection block, said lower slider and said lower transverse block are also formed into a one-piece structure.
