Abstract

This invention relates to the field of painting technology, providing a wall painting device for architectural decoration and its usage method, including a hinged seat and a base. A steering structure is hinged to the top of the hinged seat. By incorporating the steering structure, rotating the limiting nut causes it to be threaded onto the outside of a limiting rod at the bottom of the steering seat. Under the action of the limiting nut, the limiting rod moves through a limiting plate to move a limiting block into the limiting groove, thus fixing the limiting rod to the steering seat. The rotation direction of the hinged seat can be adjusted through the interaction of the limiting groove and the limiting block. The bottom of the limiting rod is hinged to the top of the hinged seat. When the steering axis of the hinged seat is parallel to the central axis of the roller, it can be used for longitudinal painting; when the steering axis is perpendicular to the central axis of the roller, it can be used for transverse painting. This device facilitates adjustment of the painting direction, thereby improving the applicability of the wall painting device for architectural decoration.

Description

Technical Field

[0001] This invention relates to the field of painting technology, and in particular to a wall painting device for architectural decoration and its method of use. Background Technology

[0002] With the continuous progress of society, the construction industry has developed vigorously. During the decoration process, the interior walls and ceilings need to be painted, so a type of architectural decoration wall painting equipment is used. The most common painting equipment is a roller brush.

[0003] To address this, patent CN216239564U discloses an assembled building wall painting device. One end of the support frame is threaded with a fixing rod, and the outer wall of the fixing rod, away from the support frame, is threaded with an inner tube. A brush tube is rotatably connected to the outer wall of the support frame, and a drain hole is provided on the outer wall of the support frame. The support frame, inner tube, and handle solve the problem that most existing wall painting devices are one-piece structures, making them inconvenient to store and transport after use. The material container solves the problem that most existing wall painting devices lack protective structures, easily causing ground pollution during use. The inner tube and handle solve the problem that most existing wall painting devices lack telescopic structures, making it impossible to adjust the length according to usage needs during use.

[0004] When painting vertical walls and the corners of the top of the wall, the assembled building wall painting equipment described above cannot fully contact the corners because the brush tube is cylindrical and the angle between the brush tube and the handle is inconvenient to adjust. Therefore, the brush tube needs to be placed vertically. When the brush tube is placed vertically, the handle needs to be kept horizontal. At this time, the user needs a stand or ladder for assistance, which makes it less applicable when used. Summary of the Invention

[0009] The top of the hinged seat is hinged with a steering structure, and the top of the steering structure is mounted with a base. The steering structure includes a flange, a steering seat, a limiting plate, a limiting rod, an internal cavity, a limiting nut, a limiting groove, and a limiting block. The flange is mounted on the bottom of the base, and the bottom of the flange is fixed with a steering seat. The top of the steering seat is provided with an internal cavity. The bottom of the internal cavity of the steering seat is evenly provided with limiting grooves. The internal cavity is provided with a limiting plate. The bottom of the limiting plate is evenly fixed with limiting blocks. The middle position of the bottom of the limiting plate is fixed with a limiting rod. The bottom of the limiting rod extends to the outside of the steering seat. The outside of the limiting rod at the bottom of the steering seat is provided with a limiting nut. Rollers are provided on both sides above the base, and both ends of the rollers are provided with disassembly and assembly structures.

[0010] The outer sides of the detachable structures at both ends of the roller are provided with protective structures, and the outer sides of the roller are provided with cloth brushes.

[0011] An adjustment structure is fixed at the bottom of the hinge seat;

[0012] The outer wall of the top of the limiting rod is threaded, and the inner wall of the limiting nut is threaded. The limiting nut and the limiting rod form a rotating structure through the threads. There are four sets of limiting grooves and limiting blocks. The limiting blocks and the steering seat form a locking structure through the limiting grooves.

[0013] The protective structure includes a cover plate, a snap-fit ​​groove, a snap-fit ​​block, and a reserved groove. The cover plate is disposed at both ends of the roller. Snap-fit ​​grooves are provided on both sides inside the roller at one end of the cover plate. Snap-fit ​​blocks are provided inside each snap-fit ​​groove. A reserved groove is provided at the edge of the cover plate near one end of the roller.

[0014] The disassembly and assembly structure includes a fixed base, fixed bolts, a connecting shaft, bearings, a fixed plate, fixed blocks, a fixed groove, and a connecting groove. The fixed groove is located on the outer wall of one side of the roller, and the connecting groove is located at both ends of the roller. Bearings are fixed inside the connecting grooves, and connecting shafts are fixed inside the bearings. The fixed base is fixed to both sides of the top of the base. One end of each connecting shaft passes through the cover plate and extends into the interior of the fixed base. Fixed bolts pass through the end of each connecting shaft away from the roller. A fixed plate is located inside the fixed groove. Fixed blocks are located at both ends inside the fixed plate. Both ends of the fixed bolts extend to the outside of the fixed base. The connecting shaft and the roller form a rotating structure through the bearings. The fixed plate and the cloth brush form an engaging structure with the roller through the fixed groove. Both ends of the fixed blocks extend into the interior of the roller.

[0015] Preferably, the snap-fit ​​groove has an "L" shaped cross-section when viewed from above, one end of the snap-fit ​​block extends to the outside of the roller and is fixedly connected to one side of the cover plate, and the snap-fit ​​block and the roller form a snap-fit ​​structure through the snap-fit ​​groove.

[0016] Preferably, the adjustment structure includes a fixed rod, a connecting tube, a fixed nut, and an extension rod. The fixed rod is fixed at the middle position of the bottom end of the hinge seat. The outer side of the bottom of the fixed rod is threaded with the connecting tube, and the inner side of the bottom of the connecting tube is threaded with the extension rod. Fixed nuts are threaded on the outer walls of the fixed rod and the extension rod at both ends of the connecting tube.

[0017] Preferably, the outer diameter of the fixing rod is equal to the outer diameter of the extension rod, and the thread directions of the fixing rod and the extension rod are designed to be opposite.

[0018] This invention also proposes a method for using a wall painting device for architectural decoration, comprising the following steps:

[0019] S1. The connecting shaft is installed inside the connecting groove via a bearing, allowing the connecting shaft and the roller to rotate via the bearing;

[0020] S2. Wrap the cloth brush around the outer wall of the roller, so that both sides of the cloth brush are inserted into the inside of the fixing groove. At this time, insert the fixing plate into the inside of the fixing groove and snap the fixing block into both ends of the fixing plate. The two ends of the fixing block extend into the inside of the roller, preventing the fixing plate from falling out of the inside of the fixing groove, thereby preventing the cloth brush from falling out of the outside of the roller.

[0021] S3. Move the cover plate to both ends of the roller so that the connecting shaft passes through the inside of the cover plate. When the snap-fit ​​block and the snap-fit ​​groove are aligned, press the cover plate. The cover plate will drive the snap-fit ​​block to move into the inside of the snap-fit ​​groove. The snap-fit ​​block and the roller snap-fit ​​each other through the snap-fit ​​groove, so that the cover plate is fixed at both ends of the roller, preventing paint from entering the bearing and affecting its rotation. The cover plate can be removed through the reserved groove.

[0022] S4. Move the rollers to both sides of the top of the base, so that the connecting shaft is placed inside the fixed seat. Use fixing bolts to pass through the fixed seat and the connecting shaft to fix the connecting shaft to the base.

[0023] S5. Pass the limit rod through the steering seat to move the limit plate into the interior cavity. Then, install the flange at the bottom of the base with bolts. Rotate the limit nut so that the limit nut is threaded onto the outside of the limit rod at the bottom of the steering seat. Under the action of the limit nut, the limit rod will move the limit block into the interior of the limit groove through the limit plate, so that the limit rod and the steering seat are fixed to each other. Through the cooperation of the limit groove and the limit block, the rotation direction of the hinge seat can be adjusted. The bottom of the limit rod is hinged to the top of the hinge seat. When the steering axis of the hinge seat is parallel to the central axis of the roller, it can be used for longitudinal painting. When the steering axis of the hinge seat is perpendicular to the central axis of the roller, it can be used for transverse painting.

[0024] S6. Rotate the connecting tube. The fixed rod and extension rod inside the connecting tube will move in opposite directions. When the fixed rod and extension rod are adjusted to the appropriate position, rotate the fixing nut so that the fixing nuts on the outside of the fixed rod and extension rod respectively abut against one end of the connecting tube, thus preventing the fixed rod and extension rod from rotating during use.

[0025] (III) Beneficial Effects

[0026] The present invention provides a wall painting device for architectural decoration and its method of use, the advantages of which are:

[0027] By incorporating a steering structure, rotating the limiting nut causes it to be threaded onto the outside of the limiting rod at the bottom of the steering seat. Under the action of the limiting nut, the limiting rod moves the limiting block into the limiting groove via the limiting plate, thus fixing the limiting rod and the steering seat together. Through the cooperation of the limiting groove and the limiting block, the rotation direction of the hinge seat can be adjusted. The bottom of the limiting rod is hinged to the top of the hinge seat. When the steering axis of the hinge seat is parallel to the central axis of the roller, it can be used for longitudinal painting; when the steering axis of the hinge seat is perpendicular to the central axis of the roller, it can be used for transverse painting. This device facilitates the adjustment of the painting direction, thereby improving the applicability of the wall painting equipment for building decoration.

[0028] By incorporating a protective structure, the cover plate is moved to both ends of the roller, allowing the connecting shaft to pass through the inside of the cover plate. When the locking block and locking groove are aligned, pressing the cover plate will cause the cover plate to move the locking block into the locking groove. The locking block and the roller are locked together through the locking groove, fixing the cover plate to both ends of the roller. The cover plate can be removed through the reserved groove. Under the action of the cover plate, paint is prevented from entering the bearing and affecting its rotation, thereby improving the convenience of using the wall painting equipment for building decoration.

[0029] By incorporating a detachable assembly structure, the brush is wrapped around the outer wall of the roller, with both sides of the brush inserted into the fixing groove. At this point, the fixing plate is inserted into the fixing groove, and the fixing block is snapped onto both ends of the fixing plate. The two ends of the fixing block extend into the inside of the roller, preventing the fixing plate from falling out of the fixing groove. The detachable assembly and disassembly of the fixing plate and fixing block facilitate the replacement of the brush, thereby extending the service life of the wall painting equipment for building decoration.

At this time, insert the fixing plate 605 into the inside of the fixing groove 607, and snap the fixing block 606 onto both ends of the fixing plate 605. The two ends of the fixing block 606 extend into the inside of the roller 8, preventing the fixing plate 605 from falling out of the inside of the fixing groove 607. The cloth brush 4 can be easily replaced by disassembling and assembling the fixing plate 605 and the fixing block 606.

[0046] See attached document Figure 6 Appendix Figure 7 and attached Figure 9 As shown, protective structures 5 are provided on the outer sides of the disassembly and assembly structures 6 at both ends of the roller 8. The protective structures 5 include cover plates 501, snap-fit ​​grooves 502, snap-fit ​​blocks 503, and reserved grooves 504. The cover plates 501 are provided at both ends of the roller 8. Snap-fit ​​grooves 502 are provided on both sides of the inside of the roller 8 at one end of the cover plate 501. Snap-fit ​​blocks 503 are provided inside the snap-fit ​​grooves 502. Reserved grooves 504 are provided at the edge of the cover plate 501 near one end of the roller 8. The top view of the snap-fit ​​groove 502 is L-shaped. One end of the snap-fit ​​block 503 extends to the outside of the roller 8 and is fixedly connected to one side of the cover plate 501. The snap-fit ​​block 503 and the roller 8 form a snap-fit ​​structure through the snap-fit ​​groove 502.

[0047] Move the cover plate 501 to both ends of the roller 8 so that the connecting shaft 603 passes through the inside of the cover plate 501. When the snap-fit ​​block 503 is aligned with the snap-fit ​​groove 502, press the cover plate 501. The cover plate 501 will drive the snap-fit ​​block 503 to move into the inside of the snap-fit ​​groove 502.

[0049] When the length needs to be adjusted, rotate the connecting tube 702. The fixing rod 701 and the extension rod 704 inside the connecting tube 702 will move in opposite directions. When the fixing rod 701 and the extension rod 704 are adjusted to the appropriate position, rotate the fixing nut 703 so that the fixing nut 703 on the outside of the fixing rod 701 and the extension rod 704 respectively abuts against one end of the connecting tube 702, thus preventing the fixing rod 701 and the extension rod 704 from rotating during use.

[0050] This invention also proposes a method for using a wall painting device for architectural decoration, comprising the following steps:

[0051] S1. The connecting shaft 603 is installed inside the connecting groove 608 via the bearing 604, so that the connecting shaft 603 and the roller 8 can rotate via the bearing 604;

[0052] S2. Wrap the cloth brush 4 around the outer wall of the roller 8, so that both sides of the cloth brush 4 are inserted into the inside of the fixing groove 607. At this time, insert the fixing plate 605 into the inside of the fixing groove 607, and snap the fixing block 606 into both ends of the fixing plate 605. The two ends of the fixing block 606 extend into the inside of the roller 8, preventing the fixing plate 605 from falling out of the inside of the fixing groove 607, thereby preventing the cloth brush 4 from falling out of the outside of the roller 8.

[0053] S3. Move the cover plate 501 to both ends of the roller 8 so that the connecting shaft 603 passes through the inside of the cover plate 501. When the snap-fit ​​block 503 is aligned with the snap-fit ​​groove 502, press the cover plate 501. The cover plate 501 will drive the snap-fit ​​block 503 to move into the inside of the snap-fit ​​groove 502. The snap-fit ​​block 503 and the roller 8 are snapped together through the snap-fit ​​groove 502, so that the cover plate 501 is fixed at both ends of the roller 8, preventing paint from entering the inside of the bearing 604 and affecting its rotation. The cover plate 501 can be removed through the reserved groove 504.

[0054] S4. Move the roller 8 to both sides of the top of the base 3, so that the connecting shaft 603 is placed inside the fixed seat 601. Use the fixing bolt 602 to pass through the fixed seat 601 and the connecting shaft 603 to fix the connecting shaft 603 to the base 3.

[0055] S5. Pass the limiting rod 204 through the steering seat 202, so that the limiting plate 203 moves into the interior cavity 205. Then, install the flange 201 at the bottom of the base 3 with bolts. Rotate the limiting nut 206 so that the limiting nut 206 is threadedly connected to the outside of the limiting rod 204 at the bottom of the steering seat 202. Under the action of the limiting nut 206, the limiting rod 204 will drive the limiting block 208 to move into the interior of the limiting groove 207 through the limiting plate 203, so that the limiting rod 204 and the steering seat 202 are fixed to each other. Through the mutual cooperation of the limiting groove 207 and the limiting block 208, the rotation direction of the hinge seat 1 can be adjusted. The bottom of the limiting rod 204 is hinged to the top of the hinge seat 1. When the steering axis of the hinge seat 1 is parallel to the central axis of the roller 8, it can be used for longitudinal painting. When the steering axis of the hinge seat 1 is perpendicular to the central axis of the roller 8, it can be used for transverse painting.

[0056] S6. Rotate the connecting tube 702. The fixing rod 701 and the extension rod 704 inside the connecting tube 702 will move in opposite directions. When the fixing rod 701 and the extension rod 704 are adjusted to a suitable position, rotate the fixing nut 703 so that the fixing nut 703 on the outside of the fixing rod 701 and the extension rod 704 respectively abuts against one end of the connecting tube 702, thus preventing the fixing rod 701 and the extension rod 704 from rotating during use.
