Description

Technical Field

[0001] The present application relates to the technical field of architectural decorative coatings, and in particular to a coating collecting device for architectural decoration grinding. Background Technique

[0002] Architectural decorative coatings are materials applied to the inner and outer surfaces of buildings, which can adhere well to the substrate material and form a complete and tough protective film. Such coatings not only have decorative properties but also can play a certain protective role for buildings, enhancing the durability of the base layer. When constructing common interior wall latex paints and epoxy floor paints for floors, a layer of coating is first applied, and then the underlying coating is ground and another layer of coating is applied to improve the coating quality.

[0003] A commonly used grinding tool at present includes a grinding machine body and a dust suction device for collecting the ground coatings. A dust-proof cover is installed on the grinding machine body, and one end of the dust-proof cover is open. The grinding head of the grinding machine body is located inside the dust-proof cover. An air suction pipe is provided on the side wall of the dust-proof cover far from the open end, and the end of the air suction pipe far from the dust-proof cover is connected to the dust suction device. An operating rod is also rotatably connected to the grinding machine body. When grinding the substrate coating, the user holds the operating rod, presses the grinding machine body against the substrate surface and grinds the coating. At this time, the side wall of the open end of the dust-proof cover fits against the substrate surface, and the ground coating dust is collected by the dust suction device.

[0004] In view of the above related technologies, when it is necessary to grind the architectural decorative coating on the wall surface, the user holds the operating rod, presses the grinding machine body against the wall surface, and at the same time, the user needs to swing the operating rod back and forth to grind the wall surface with the grinding machine body. When the distance between two opposite walls is small, the angle between the operating rod and the wall surface is small, which is not conducive to the user applying a force perpendicular to the wall surface direction to the operating rod, and it is not easy to keep the grinding machine body pressed against the wall surface, reducing the quality of coating grinding. Content of the Utility Model

[0005] In order to facilitate grinding the architectural decorative coating on the wall surface of a narrow space and improve the grinding quality of the coating, the present application provides a coating collecting device for architectural decoration grinding.

[0006] The coating collecting device for architectural decoration grinding provided by the present application adopts the following technical solutions:

[0007] A paint collecting device for building decoration grinding, including a grinding machine body movably located between two opposite walls and a mounting plate. A grinding head is rotatably arranged on the grinding machine body, and the grinding head is movably attached to the surface of one wall. A fixing rod is also rotatably arranged on the grinding machine body. The rotation axis of the fixing rod is perpendicular to the rotation axis of the grinding head, and the fixing rod is located on the side of the grinding machine body away from the grinding head. A support rod is rotatably arranged at one end of the fixing rod away from the grinding machine body. A universal wheel is arranged at one end of the support rod away from its rotation axis, and the universal wheel is movably attached to the surface of the other wall. An elastic member is arranged on the rotation axis of the support rod, and the elastic member always makes the universal wheel fit and press tightly against the wall surface. A locking component for fixing the support rod and the fixing rod is arranged on the fixing rod. An adsorption component for collecting the building decoration paint after being ground by the grinding machine body is arranged on the mounting plate.

[0008] By adopting the above technical solution, when grinding the building decoration paint on the surfaces of two opposite walls with a small distance, the user places the grinding machine body and the fixing rod between the two walls, makes the grinding head fit against the surface of one wall, and at the same time, the elastic member drives the support rod to rotate, so that one end of the support rod away from its rotation axis moves away from the fixing rod, thereby making the universal wheel press tightly against the surface of the other wall, realizing that the grinding head presses tightly against the wall surface. When the user drives the fixing rod to move along the wall surface and makes the grinding machine body grind the wall surface, the user does not need to apply a force perpendicular to the wall surface direction on the grinding machine body to realize that the grinding head presses tightly against the wall surface, which is convenient for the user to grind the building decoration paint on the wall surface and improves the grinding quality of the paint.

[0009] When it is necessary to grind the surface of a conventional wall, the user rotates the support rod to a position parallel to the fixing rod and fixes the support rod through the locking component, realizing the switching of two working states, which is convenient for use under different working conditions.

[0010] When grinding the wall surface, the adsorption component absorbs and cleans the dust of the ground building decoration paint, so that the paint dust is not easily attached to the wall surface, which is convenient for the user to observe the grinding situation and improves the grinding efficiency and quality.

[0011] Optionally, a receiving groove is formed on the side wall of the fixing rod away from the grinding head, and the support rod is movably located in the receiving groove. The locking component includes a locking block rotatably arranged on the inner side wall of the receiving groove. A locking groove for the locking block to rotate is formed on the side wall of the support rod. The locking block is movably located in the locking groove, and the locking block is movably pressed against the inner side wall of the locking groove.

[0012] By adopting the above technical solution, when fixing the support rod and the fixed rod, the user rotates the support rod to make the support rod located in the receiving groove, and then the user drives the locking block to rotate to make the locking block located in the locking groove. At this time, the locking block abuts against the inner side wall of the locking groove, making it difficult for the support rod to rotate, realizing the fixation of the support rod, and facilitating the user's grinding operation on the surface of a conventional wall.

[0013] Optionally, a sliding groove is formed in the side wall of the support rod away from its rotation axis. An expansion rod is slidably arranged in the sliding groove. One end of the expansion rod protrudes out of the sliding groove. The universal wheel is rotatably arranged at one end of the expansion rod protruding out of the sliding groove. A fixing component for fixing the expansion rod and the support rod is arranged on the support rod.

[0014] By adopting the above technical solution, when it is necessary to grind the surfaces of two relatively close walls, the user makes the grinding head fit against the surface of one side wall and makes the universal wheel abut against the surface of the other side wall. Then the user slides the expansion rod in the sliding groove to adjust the length of the expansion rod protruding out of the sliding groove, so that the universal wheel and the grinding head are in a relative position, so that the grinding head always remains in contact with the wall surface and is not prone to tilt. Then, the expansion rod and the support rod are fixed by the fixing component, so that the universal wheel and the grinding head are always in a relative position, improving the stability of the grinding head abutting against the wall surface, and thus improving the grinding quality.

[0015] Optionally, the fixing component includes a fixed rack slidably arranged in the sliding groove. The fixed rack is connected to the expansion rod. A fixed block is slidably arranged on the support rod. The fixed block is movably inserted into the tooth groove of the fixed rack. An operating handle is arranged on the side wall of the fixed block away from the fixed rack. One end of the operating handle away from the fixed block protrudes out of the outer side wall of the support rod. A reset member is arranged on the operating handle. The reset member makes the fixed block slide towards the direction close to the fixed rack.

[0016] By adopting the above technical solution, when adjusting the length of the expansion rod protruding out of the sliding groove, the user pulls the operating handle in the direction away from the fixed rack and drives the fixed block to slide in the direction away from the fixed rack, so that the fixed block is separated from the fixed rack, making it difficult for the fixed block to hinder the sliding of the fixed rack. Then the user drives the expansion rod to slide to adjust the position of the universal wheel, facilitating the adjustment of the position of the universal wheel.

[0017] After the adjustment is completed, the user releases the operating handle. The reset member drives the operating handle and the fixed block to move synchronously in the direction close to the fixed rack, and makes the fixed block inserted into the tooth groove of the fixed rack, making it difficult for the fixed rack to slide, realizing the fixation of the expansion rod and the support rod, so that the universal wheel and the grinding head are always in a relative position. The fixation operation of the expansion rod is simple and fast.

[0018] Optionally, the adsorption assembly includes a dust-proof cover provided on the main body of the grinding machine. The dust-proof cover is located on the side wall of the main body of the grinding machine close to the grinding head. One end of the dust-proof cover away from the main body of the grinding machine is open. The dust-proof cover is movably attached to the wall surface. The grinding head is located inside the dust-proof cover. An air suction member for absorbing the ground coating dust in the dust-proof cover is provided on the mounting plate.

[0019] By adopting the above technical solution, when grinding the wall surface, the grinding head abuts against the wall surface, and at the same time, the side wall of the open end of the dust-proof cover also abuts against the wall surface, so that the ground building decoration coating dust is not easily leaked, and thus the coating dust is not easily attached to the wall surface, which is convenient for the user to observe the grinding situation. Moreover, the coating dust is concentrated in the dust-proof cover, and then the air suction member is used to absorb and clean the coating dust in the dust-proof cover, improving the cleaning efficiency.

[0020] Optionally, the air suction member includes a connecting hose provided on the dust-proof cover. The connecting hose is communicated with the inside of the dust-proof cover. One end of the fixing rod away from the main body of the grinding machine is detachably provided with an operation tube. The end of the connecting hose away from the dust-proof cover is communicated with the operation tube. One end of the operation tube away from the fixing rod is detachably provided with a suction hose. The operation tube is communicated with the suction hose. A collection box is provided on the mounting plate. An air pump is provided on the collection box. The air pump is communicated with the collection box. The end of the suction hose away from the operation tube is communicated with the air pump. A placement box is provided on the side wall of the mounting plate close to the collection box. A moving wheel is provided on the side wall of the mounting plate away from the collection box. The moving wheel is in contact with the ground.

[0021] By adopting the above technical solution, when grinding the wall surface, the provided operation tube is convenient for the user to hold, and is convenient for the user to drive the main body of the grinding machine to grind. At the same time, when the air pump works, the ground coating dust enters the collection box through the connecting hose, the operation tube and the suction hose in sequence, so as to realize the collection of the coating dust, which is convenient for the user to observe the grinding situation and improves the grinding efficiency and quality.

[0022] After the grinding work is completed, the user separates the suction hose from the operation tube and the connecting hose from the operation tube, and then the user separates the operation tube from the fixing rod, which is convenient for the user to put the disassembled operation tube and fixing rod into the placement box, realizing the storage of the operation tube and the fixing rod, reducing the occupied space of the overall device when not grinding. Then the user pushes the mounting plate, which is convenient for the user to move the overall device to the next working location.

[0023] Optionally, the adsorption assembly further includes a fixed cylinder disposed on the grinding machine body. The fixed cylinder is arranged coaxially with the grinding head. The dust-proof cover is movably connected to the fixed cylinder. A guiding hole corresponding to the dust-proof cover is formed in the side wall of the dust-proof cover away from the opening end. The outer peripheral wall of the fixed cylinder is movably abutted against the inner side wall of the guiding hole. The dust-proof cover is in the shape of a Reuleaux triangle, and a flexible sealing cover for movably blocking the guiding hole is provided on the fixed cylinder.

[0024] By adopting the above technical solution, when grinding the wall surface, the provided sealing cover makes it difficult for paint dust to leak out from the guiding hole. When grinding to the corner between the wall surface and the adjacent wall, the user makes one outer side wall of the dust-proof cover fit against the adjacent wall surface, and makes the grinding machine body continue to move in the direction closer to the adjacent wall surface until the outer peripheral wall of the fixed cylinder abuts against the inner side wall of the guiding hole, reducing the distance between the grinding head and the inner side wall of the dust-proof cover and reducing the grinding dead angle.

[0025] When grinding to the corner between the wall surface and the two adjacent walls, the user makes the other adjacent outer side wall of the dust-proof cover fit against the other adjacent wall surface, and then the user makes the grinding machine body continue to move in the direction closer to the other adjacent wall surface until the outer peripheral wall of the fixed cylinder abuts against the inner side wall of the guiding hole, reducing the distance between the grinding head and the two adjacent inner side walls of the dust-proof cover. Since the dust-proof cover is in the shape of a Reuleaux triangle, at this time, the dead angle of the coverage area of the dust-proof cover on the wall surface is small, further reducing the grinding dead angle and improving the grinding quality.

[0026] Optionally, a central spring is provided on the outer peripheral wall of the fixed cylinder. One end of the central spring away from the fixed cylinder is connected to the side wall of the dust-proof cover away from the opening end. There are three central springs, and the three central springs are arranged at equal intervals along the circumferential direction of the fixed cylinder.

[0027] By adopting the above technical solution, when grinding the wall surface, due to the action of the three central springs, the fixed cylinder is located at the center of the dust-proof cover, making it difficult for the dust-proof cover to shake relative to the grinding machine body, reducing the risk of paint dust leakage, improving the absorption and cleaning effect of the paint dust, and at the same time reducing the collision between the dust-proof cover and the wall, improving the service life of the dust-proof cover.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. With the grinding machine body, grinding head, fixed rod, support rod, universal wheels, elastic members, telescopic rods, locking components and fixing components provided, when it is necessary to grind the architectural decorative coatings on the surfaces of two relatively close walls, the user makes the grinding head fit against the surface of one side wall. At the same time, the elastic member drives the support rod to rotate, so that the universal wheels abut against the surface of the other side wall, realizing that the grinding head abuts against the wall surface. Then the user adjusts the length of the telescopic rod protruding from the sliding groove to make the universal wheels and the grinding head in a relative position, and fixes the telescopic rod through the fixing component, so that the universal wheels and the grinding head are always in a relative position, improving the stability of the grinding head abutting against the wall surface, thereby improving the grinding quality. When the user drives the fixed rod to move along the wall surface and grind the wall surface, the user does not need to apply a force perpendicular to the wall surface direction on the grinding machine body to realize that the grinding head abuts against the wall surface, which is convenient for the user to grind the architectural decorative coatings on the wall surface and improves the grinding quality of the coatings;

[0030] When it is necessary to grind the surface of a conventional wall, the user rotates the support rod to a position parallel to the fixed rod and fixes the support rod and the fixed rod through the locking component, realizing the switching between two working states, which is convenient for use under different working conditions;

[0031] 2. With the mounting plate, dust-proof cover, connecting hose, operation tube, suction hose, air pump, collection box, placement box and moving wheels provided, when grinding the wall surface, the operation tube is convenient for the user to hold and drive the grinding machine body to grind. At the same time, the coated dust after grinding is not easy to leak out in the dust-proof cover. Then, through the air pump, the coated dust after grinding enters the collection box through the connecting hose, operation tube and suction hose in sequence, thereby realizing the absorption and cleaning of the coated dust, making the coated dust not easy to adhere to the wall surface, being convenient for the user to observe the grinding situation, and improving the grinding efficiency and quality;

[0032] After grinding, the user separates the operation tube from the connecting hose and the operation tube from the suction hose, and also separates the operation tube from the fixed rod. Then the user puts the operation tube and the fixed rod into the placement box to reduce the occupied space of the overall device when not grinding. Then the user pushes the mounting plate, which is convenient for the user to move the overall mobile device to the next working location.

[0033] 3. The dust cover is in the shape of a Leroy triangle through the set fixed cylinder, guide hole, sealing cover and center spring. When grinding to the corner between the wall surface and the adjacent wall, the fixed cylinder can continue to move in the direction close to the adjacent wall, reducing the distance between the grinding head and the inner wall of the dust cover. When grinding to the corner between the wall surface and the two adjacent walls, the fixed cylinder can continue to move in the direction close to the adjacent wall, reducing the distance between the grinding head and the other inner wall adjacent to the dust cover. Due to the shape of the dust cover, the dead angle covered by the dust cover on the wall surface is smaller at this time, thereby reducing the grinding dead angle and improving the grinding quality. Through the action of the three center springs, the fixed cylinder is located in the center of the dust cover, which makes it difficult for the dust cover to shake relative to the grinder body, reducing the risk of paint dust leakage, while reducing the collision between the dust cover and the wall, and improving the service life of the dust cover.

[0039] The following is combined with Figures 1-4 This application is described in further detail.

[0040] The present application embodiment discloses a paint collection device for architectural decoration and polishing. Figure 1 and Figure 2, a paint collection device for building decoration grinding includes a mounting plate 2 horizontally placed on the ground and a grinding machine body 1 movably arranged between two walls. A grinding head 11 is rotatably connected to the grinding machine body 1, and the grinding head 11 is movably attached to the surface of one wall. When the grinding head 11 is in contact with the wall surface, the rotation axis of the grinding head 11 is perpendicular to the wall surface. A plurality of moving wheels 23 are fixed to the bottom side of the mounting plate 2. In this application, there are four groups of moving wheels 23, and the four groups of moving wheels 23 are respectively located at the four corners of the bottom of the mounting plate 2. A placement box 21 is fixed to the top side of the mounting plate 2, and a handle 22 is also fixed to the top side of the mounting plate 2.

[0041] In order to collect the building paint polished by the grinding machine body 1, an adsorption component 5 is provided on the mounting plate 2. Refer to Figure 1 and Figure 2 , the adsorption component 5 includes a fixed cylinder 53 fixed to the grinding machine body 1. The fixed cylinder 53 is fixed to the side wall of the grinding machine body 1 close to the grinding head 11. A dust-proof cover 51 is movably connected to the fixed cylinder 53, and the fixed cylinder 53 is arranged coaxially with the grinding head 11. One end of the dust-proof cover 51 away from the grinding machine body 1 is open, and the side wall of the open end of the dust-proof cover 51 is movably attached to the wall surface. The grinding head 11 is located inside the dust-proof cover 51. The dust-proof cover 51 is in the shape of a Reuleaux triangle. A guiding hole 54 corresponding to the shape of the dust-proof cover 51 is formed on the side wall of the dust-proof cover 51 away from the open end. The outer peripheral wall of the fixed cylinder 53 is movably abutted against the inner side wall of the guiding hole 54. A flexible sealing cover 55 for movably blocking the guiding hole 54 is fixed to the fixed cylinder 53.

[0042] In order to prevent the dust-proof cover 51 from shaking relative to the grinding machine body 1, a central spring 56 is fixed to the outer peripheral wall of the fixed cylinder 53. One end of the central spring 56 away from the fixed cylinder 53 is fixedly connected to the side wall of the dust-proof cover 51 away from the open end. There are three central springs 56, and the three central springs 56 are arranged at equal intervals along the circumference of the fixed cylinder 53.

[0043] In order to absorb the polished paint dust inside the dust-proof cover 51, an air suction member 52 is provided on the mounting plate 2. Refer to Figure 1, the air suction member 52 includes a connecting hose 521 fixed to the side wall of the dust-proof cover 51. The connecting hose 521 is communicated inside the dust-proof cover 51. One end of the fixing rod 12 away from the grinding machine body 1 is detachably connected with an operation tube 522. One end of the connecting hose 521 away from the dust-proof cover 51 is connected to the outer peripheral wall of the operation tube 522. The connecting hose 521 is communicated with the operation tube 522. One end of the operation tube 522 away from the fixing rod 12 is detachably connected with an air suction hose 523. The air suction hose 523 is communicated with the operation tube 522. A collection box 524 is fixed to the top side of the mounting plate 2. An air pump 525 is fixed to the collection box 524. The air pump 525 is communicated with the collection box 524. One end of the air suction hose 523 away from the operation tube 522 is connected to the air pump 525.

[0044] When grinding the wall surface, the user makes the grinding head 11 fit with the wall surface. The operation tube 522 is provided to facilitate the user's grip and facilitate the user to drive the grinding machine body 1 to grind the wall surface. At this time, the side wall of the open end of the dust-proof cover 51 also fits with the wall surface, so that the dust of the architectural decorative paint after grinding is not easily leaked. The provided sealing cover 55 makes the paint dust not easily leak from the guiding hole 54. Through the action of the three central springs 56, the fixing cylinder 53 is located at the center of the dust-proof cover 51, and it is not easy for the dust-proof cover 51 to shake relative to the grinding machine body 1, further reducing the risk of paint dust leakage, so that the paint dust is not easily attached to the wall surface, facilitating the user to observe the grinding situation and improving the grinding efficiency and quality.

[0045] At the same time, the air pump 525 works to make the paint dust after grinding enter the collection box 524 through the connecting hose 521, the operation tube 522 and the air suction hose 523 in sequence, so as to realize the absorption and cleaning of the paint dust. Since the paint dust is concentrated in the dust-proof cover 51, the efficiency of paint dust absorption is improved.

[0046] When grinding to the corner between the wall surface and the adjacent wall, the user makes one outer side wall of the dust-proof cover 51 fit with the adjacent wall surface. At this time, the central spring 56 is provided to reduce the collision generated between the dust-proof cover 51 and the wall, improving the service life of the dust-proof cover 51. Then the user pushes the grinding machine body 1 to continue moving in the direction close to the adjacent wall surface until the outer peripheral wall of the fixing cylinder 53 abuts against the inner side wall of the guiding hole 54, reducing the distance between the grinding head 11 and the inner side wall of the dust-proof cover 51 and reducing the grinding dead angle.

[0047] When grinding to the surface of the wall and the corners of two adjacent walls, the user makes the outer wall of the dust cover 51 adjacent to another wall surface fit with the surface of the adjacent other wall. Then the user pushes the grinding machine body 1 to continue moving in the direction closer to the surface of the adjacent other wall until the outer peripheral wall of the fixed cylinder 53 abuts against the inner wall of the guide hole 54, reducing the distance between the grinding head 11 and the two inner walls of the dust cover 51 adjacent to each other. Since the dust cover 51 is in the shape of a Reuleaux triangle, at this time, the dead angle of the coverage area of the dust cover 51 on the wall surface is small, further reducing the grinding dead angle and improving the grinding quality.

[0048] After the grinding work is completed, the user separates the suction hose 523 from the operation tube 522 and the connecting hose 521 from the operation tube 522. Then the user separates the operation tube 522 from the fixed rod 12, which is convenient for the user to put the disassembled operation tube 522 and fixed rod 12 into the placement box 21, realizing the storage of the operation tube 522 and the fixed rod 12, reducing the occupied space of the overall device when not grinding. Then the user pushes the handle 22 to drive the mounting plate 2 to move, which is convenient for the user to move the overall device to the next working location.

[0049] Furthermore, in order to facilitate the grinding of the architectural decorative coatings on the relatively two wall surfaces with a small distance, referring to Figure 2 and Figure 3 , a fixed rod 12 is also rotatably connected to the grinding machine body 1. The rotation axis of the fixed rod 12 is perpendicular to the rotation axis of the grinding head 11. The fixed rod 12 is located on the side of the grinding machine body 1 away from the grinding head 11. One end of the fixed rod 12 away from the grinding machine body 1 is rotatably connected to a support rod 13. The rotation axis of the support rod 13 is parallel to the rotation axis of the fixed rod 12. A sliding groove 131 is formed on the side wall of the support rod 13 away from its rotating shaft. An expansion rod 16 is slidably connected in the sliding groove 131. One end of the expansion rod 16 protrudes from the sliding groove 131. A universal wheel 14 is fixed to the end of the expansion rod 16 protruding from the sliding groove 131. The universal wheel 14 and the grinding head 11 are located on both sides of the fixed rod 12 respectively. The universal wheel 14 is in active contact with the surface of the other wall. An elastic member 15 is provided at the rotating shaft of the support rod 13. The elastic member 15 always makes the universal wheel 14 fit and abut against the wall surface tightly. In this application, the elastic member 15 is a tightening torsion spring.

[0050] In order to fix the expansion rod 16 and the support rod 13 and keep the relative positions of the universal wheel 14 and the grinding head 11 constant, a fixing assembly 4 is provided on the support rod 13. Referring to Figure 2 and Figure 3, the fixing component 4 includes a fixing rack 41 slidably arranged in the sliding groove 131. The fixing rack 41 is fixedly connected to the telescopic rod 16. A fixing block 42 is slidably connected to the support rod 13. The sliding direction of the fixing block 42 is perpendicular to the outer side wall of the support rod 13 and perpendicular to the rotation axis of the support rod 13. The fixing block 42 is movably inserted into the tooth groove of the fixing rack 41. An operating handle 43 is fixed to the side wall of the fixing block 42 away from the fixing rack 41. One end of the operating handle 43 away from the fixing block 42 protrudes from the outer side wall of the support rod 13, and the end of the operating handle 43 protruding from the outer side wall of the support rod 13 is in a large-head shape, which is convenient for the user to pull. A reset member 44 is fixed between the large-head end of the operating handle 43 and the support rod 13. The reset member 44 slides the fixing block 42 in the direction close to the fixing rack 41. In this application, the reset member 44 is a reset spring.

[0051] When it is necessary to polish the architectural decorative coating on the surfaces of two relatively close walls, the user places the polishing machine body 1 and the fixing rod 12 between the two walls, and makes the polishing head 11 fit against the surface of one side wall. At the same time, the tightening torsion spring drives the support rod 13 to rotate, so that the end of the support rod 13 away from its rotation axis moves in the direction away from the fixing rod 12, so that the universal wheel 14 abuts against the surface of the other side wall, so as to realize that the polishing head 11 abuts against the wall surface.

[0052] Then the user pulls the large-head end of the operating handle 43, so that the operating handle 43 and the fixing block 42 both slide in the direction away from the fixing rack 41, so that the fixing block 42 is separated from the fixing rack 41, and further makes the fixing block 42 not easily hinder the sliding of the fixing rack 41. Then the user drives the telescopic rod 16 to slide in the sliding groove 131 to adjust the length of the sliding rod protruding from the sliding groove 131, so that the universal wheel 14 and the polishing head 11 are in a relative position, so that the polishing head 11 always fits against the wall surface and is not easily tilted, improving the polishing quality. Then the user releases the operating handle 43, and the reset spring drives the operating handle 43 to move in the direction close to the fixing rack 41, driving the fixing block 42 to insert into the tooth groove of the fixing rack 41, making the fixing rack 41 not easily slide, realizing the fixation of the telescopic rod 16 and the support rod 13, so that the universal wheel 14 and the polishing head 11 are always in a relative position, improving the stability of the polishing head 11 abutting against the wall surface, further improving the polishing quality, and at the same time, the fixation operation of the telescopic rod 16 is convenient.

[0053] When the user holds the operating tube and drives the fixing rod 12 to move along the wall surface and makes the polishing machine body 1 polish the wall surface, the user does not need to apply a force perpendicular to the wall surface direction on the polishing machine body 1 to realize that the polishing head 11 abuts against the wall surface, which is convenient for the user to polish the architectural decorative coating on the wall surface and improves the polishing quality of the coating.

[0054] Furthermore, in order to fix the support rod 13 when polishing a conventional wall, a locking assembly 3 is provided on the fixing rod 12. Figure 3 and Figure 4 The fixing rod 12 is provided with a receiving groove 121 on the side wall away from the grinding head 11, the supporting rod 13 is movably located in the receiving groove 121, and the supporting rod 13 is movably fitted with the inner side wall of the receiving groove 121, the locking assembly 3 includes a locking block 31 rotatably connected to the inner side wall of the receiving groove 121, the rotation axis of the locking block 31 is perpendicular to the inner bottom wall of the receiving groove 121, and the outer side wall of the supporting rod 13 is provided with a locking groove 32 for the locking block 31 to rotate, the locking block 31 is movably located in the locking groove 32, and the locking assembly 3 includes a locking block 31 rotatably connected to the inner side wall of the receiving groove 121, and the rotation axis of the locking block 31 is perpendicular to the inner bottom wall of the receiving groove 121. The block 31 is movably pressed against the inner wall of the locking groove 32. In order to facilitate the user to rotate the locking block 31, a toggle handle 33 is fixed to the locking block 31. The toggle handle 33 and the locking block 31 are arranged perpendicular to each other. A rotating groove 34 for the toggle handle 33 to rotate is opened on the fixed rod 12. One end of the toggle handle 33 away from the locking block 31 is movably located in the rotating groove 34. When the toggle handle 33 is rotated to the position where the locking block 31 is separated from the locking groove 32, the side wall of the locking block 31 is consistent with the inner wall of the accommodating groove 121.

[0055] When it is necessary to polish the architectural decorative paint on the surfaces of two relatively small walls, the user rotates the toggle handle 33 and separates the rotating handle from the rotating groove 34. At this time, the rotating handle drives the locking block 31 to rotate, so that the locking block 31 is separated from the locking groove 32, so that the locking block 31 is not easy to hinder the rotation of the support rod 13, thereby facilitating the torsion spring to drive the support rod 13 and the universal wheel 14 to rotate, so that the universal wheel 14 is pressed against the other wall surface, which is convenient for polishing the relatively small wall surfaces.

[0056] When it is necessary to polish the conventional wall surface, the user rotates the support rod 13 until the support rod 13 is located in the accommodating groove 121, and then the user drives the toggle handle 33 to rotate and drives the locking block 31 to rotate, so that the end of the toggle handle 33 away from the locking block 31 moves toward the direction close to the rotation groove 34 until the locking block 31 is located in the locking groove 32 and is tightly against the inner wall of the locking groove 32, so that the support rod 13 is not easy to rotate, thereby fixing the support rod 13 and the fixing rod 12, thereby realizing the switching of the two working states, which is convenient for the user to polish the wall surface under different working conditions.

[0057] The implementation principle of the paint collecting device for architectural decoration polishing in the embodiment of the present application is as follows: when it is necessary to polish the architectural decoration paint on the surfaces of two relatively small walls, the user makes the polishing head 11 and the dust cover 51 fit the wall surface on one side. At this time, the elastic member 15 drives the fixing rod 12 to rotate, so that the universal wheel 14 is pressed against the wall surface on the other side. Then the user pulls the operating handle 43 to separate the fixing block 42 from the fixed rack 41, and adjusts the length of the telescopic rod 16 protruding from the sliding groove 131, so that the universal wheel 14 is in a position corresponding to the polishing head 11. Then the user releases the operating handle 43, and the reset member 44 drives the operating handle 43 and the fixing block 42 to move synchronously in the direction close to the fixed rack 41, so that the fixing block 42 is inserted into the tooth groove of the fixed rack 41, so that the fixed rack 41 is not easy to slide, and the telescopic rod 16 is fixed, so as to achieve the constant relative position of the universal wheel 14 and the polishing head 11, and improve the stability of the polishing head 11 pressed against the wall surface.

[0058] Then the user holds the operating tube 522, drives the fixing rod 12 and the grinder body 1 to move along the wall surface, and grinds the wall surface. When grinding to the corner between the wall surface and the adjacent wall, the user makes an outer wall of the dust cover 51 fit with the adjacent wall surface, and makes the grinder body 1 continue to move toward the adjacent wall surface until the outer wall of the fixing tube 53 is tightly pressed against the inner wall of the guide hole 54, thereby reducing the distance between the grinding head 11 and the inner wall of the dust cover 51 and reducing the grinding blind angle.

[0059] When grinding to the corner between the wall surface and the two adjacent walls, the user makes the other adjacent outer wall of the dust cover 51 fit with the other adjacent wall surface, and then the user makes the grinder body 1 continue to move toward the direction close to the other adjacent wall surface until the outer peripheral wall of the fixed cylinder 53 is tightly pressed against the inner wall of the guide hole 54, thereby reducing the distance between the grinding head 11 and the two adjacent inner walls of the dust cover 51, and further reducing the grinding blind angle.

[0060] At the same time, the sealing cover 55 movably blocks the guide air, so that the paint dust generated by grinding is concentrated in the dust cover 51, and the air pump 525 works to allow the paint dust to enter the collection box 524 through the connecting hose 521, the operating tube 522 and the suction hose 523 in turn, thereby absorbing and cleaning the paint dust.

[0061] When a conventional wall needs to be polished, the user rotates the support rod 13 so that the support rod 13 is located in the accommodating groove 121, and then the user rotates the toggle handle 33 so that the toggle handle 33 is located in the rotating groove 34. At this time, the locking block 31 rotates to the locking groove 32 to fix the support rod 13 and the fixing rod 12.

[0062] After grinding is completed, the user separates the suction hose 523 from the operation tube 522, and also separates the connection hose 521 from the operation tube 522. Then, the user separates the operation tube 522 from the fixed rod 12, and places the operation tube 522 and the fixed rod 12 into the storage box 21 to achieve the storage of the operation tube 522 and the fixed rod 12. Then, the user pushes the handle 22 to drive the mounting plate 2 to move, facilitating the user to move the entire device to the next working location.

[0063] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
