Description

Technical Field

[0001] This invention relates to the field of building construction, and more specifically to a self-priming waterproof coating applicator for building construction. Background Technology

[0002] Thermal insulation and waterproof coating is a new type of green waterproof material based on high molecular polymers. It has good waterproof, moisture-proof, seepage-proof, anti-aging, anti-pollution and weather-resistant properties. It can be directly sprayed or brushed onto the interior and exterior walls of buildings, basements, tunnels, canals, swimming pools and other places for waterproof and mildew prevention. When decorating a house, it is necessary to apply thermal insulation and waterproof coating to the exterior walls. However, people cannot reach the high walls to apply the coating, and using ladders poses safety hazards. Therefore, it is necessary to use a coating application device.

[0003] However, when using the applicator, paint dripping is likely to occur, and workers should stay away from the wall surface during application to avoid paint dripping onto them. Also, flocculent material from the wall surface may adhere to the applicator during application, affecting the application effect. To address these issues, a self-priming waterproof paint applicator for building construction is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is as follows: A self-priming waterproof coating applicator for building construction, comprising a coating component, a main rod rotatably connected to the outer surface of the coating component, an adjusting component fixedly connected to the outer surface of the main rod, and a connecting pipe provided inside the main rod, the outer surface of the connecting pipe being in contact with the inner wall of the main rod.

[0005] The coating component is installed at the end of the main rod furthest from the adjusting component. By including the coating component, it is ensured that no paint drips during wall coating, thus preventing interference with subsequent cleaning. The coating component includes a frame, inside which an air pump is installed. The inner wall of the frame is fixedly connected to the outer surface of the air pump. Symmetrically arranged on the outer surface of the air pump are diversion pipes. The air pump on the coating component draws paint from the diversion pipes through the connecting pipes, and then evenly distributes it onto the coating roller through the inner pipe, thus ensuring that the coating roller evenly applies paint to the wall surface. The outer surface of the air pump is fixedly connected to the inner wall of the diversion pipes. The end of the diverter pipe away from the air pump is rotatably connected to an inner tube. A brush roller is fixedly connected to the outer surface of the inner tube. A connecting frame is fixedly connected to the outer surface of the frame. Support rods are symmetrically arranged inside the connecting frame. Since the paint penetrates from the inside of the brush roller to the outside, the probability of paint dripping from the brush roller is reduced. Since the application component is equipped with a scraping component, when the application component encounters flocculent matter during application, it can be cleaned by the scraping component to prevent it from adhering to the brush roller and affecting its subsequent application effect. The inner wall of the connecting frame is rotatably connected to the outer surface of the support rod. A plug-in post is fixedly connected to the end of the support rod away from the connecting frame.

[0006] An adjusting component, installed on the outer surface of the main rod, controls the worker's stance when applying paint to the wall, preventing paint drips onto the worker. The adjusting component includes a secondary rod with a fixed plate sleeved on its outer surface. An outer ring is fixedly connected to the outer surface of the fixed plate, and a turning plate is rotatably connected to the bottom of the outer ring. The turning plate controls the angle between the secondary rod and the main rod. When the worker uses the painting component, contact with the wall and pulls the secondary rod, the angle between the secondary rod and the main rod changes, causing the outer ring to move the turning plate. This causes the connecting plate to press downwards, compressing a compression spring. A collar is rotatably connected to the end of the turning plate away from the outer ring. The adjusting component adjusts the angle between the main rod and the secondary rod, thus allowing the painting component to apply paint to the wall more precisely. During application, the worker will not be positioned directly beneath the application component, thus preventing paint drips onto their body. A connecting plate is fixedly connected to the end of the auxiliary rod near the application component. A compression spring is fixedly connected to the bottom of the connecting plate. When compressed by the connecting plate, the compression spring contracts and deforms, causing the top of the guide rod on the retaining ring to enter the limiting cylinder. This changes the angle between the main rod and the auxiliary rod. The pressure exerted by the connecting plate on the compression spring ensures the adhesion between the application component and the wall. A retaining ring is fixedly connected to the bottom of the compression spring. Adjustment components allow control of the contact force between the application component and the wall, effectively controlling the application depth. Furthermore, adjusting the contact force does not damage the main rod. A guide rod is fixedly connected to the top of the retaining ring, and a limiting cylinder is fixedly connected to the top of the connecting plate.

[0007] Preferably, there are two diversion tubes located inside the frame, two insertion posts with their outer surfaces rotatably connected to the inner wall of the main rod, a connecting tube located inside the main rod with one end of the connecting tube near the applicator fixedly connected to the surface of the air pump, a scraping component fixedly connected to the top of the frame, and a collecting component fixedly connected to the bottom of the frame.

[0008] Preferably, the scraping component includes a cover plate. By providing the scraping component, the content of fibrous material adhering to the paint roller can be reduced, thus preventing the paint roller from affecting its painting effect due to excessive fibrous material adhering to the surface when painting the wall. The cover plate has symmetrically arranged rotating disks at both ends, and the two ends of the cover plate are rotatably connected to the opposite sides of the rotating disks. A telescopic rod is fixedly connected to the bottom of the rotating disk. When the paint roller is in use, the height of the cover plate is controlled by the telescopic rod, and then the placement angle of the cover plate is controlled by the rotating disk, allowing the scraping component to clean the fibrous material through the protrusions. The bottom of the cover plate is evenly provided with... The cover plate is fixedly connected to the outer surface of the protrusion. A limit frame is evenly provided at the bottom of the cover plate, and the bottom of the cover plate is fixedly connected to the outer surface of the limit frame. A rotating rod is provided inside the limit frame, and the inner wall of the limit frame is rotatably connected to the outer surface of the rotating rod. When too much flocculent material is retained in the gap of the protrusion, the rotating rod inside the limit frame is rotated, so that multiple collection discs provided on the surface of the rotating rod pull the flocculent material out of the gap of the protrusion, thereby reducing the content of flocculent material mixed in the gap of the protrusion. Collection discs are evenly provided on the outer surface of the rotating rod, and the outer surface of the rotating rod is fixedly connected to the inner wall of the collection disc.

[0009] Preferably, there are two telescopic rods, and the bottom of the telescopic rods is fixedly connected to the inner wall of the frame. The collar is located below the auxiliary rod, and the inner wall of the collar is fixedly connected to the outer surface of the main rod. The axis of the coating roller is located on the same horizontal plane as the axis of the frame, and both ends of the coating roller are rotatably connected to the inner wall of the frame.

[0010] Preferably, the collecting component includes a collecting frame. By setting the collecting component, paint dripping from the brush roller during use can be collected into the collecting frame, thereby preventing paint from dripping during application and thus dripping onto workers or the ground, affecting subsequent cleaning work. The collecting frame has symmetrically arranged inclined plates inside, which shorten the paint flow path and prevent excessive paint adhesion within the collecting frame. The inner wall of the collecting frame is fixedly connected to the bottom of the inclined plates. Side plates are symmetrically arranged at both ends of the collecting frame, and the outer surfaces of the side plates are fixedly connected to both ends of the collecting frame. A contraction spring is installed inside the side plate, and the outer surface of the contraction spring is fixedly connected to the inner wall of the side plate. When the application component is in use, the positioning rod and the rotating plate interact... The collection frame is rotated so that it remains below the paint roller. Then, the collection frame is brought into contact with the wall, ensuring the bonding plate on one side of the collection frame adheres to the wall, preventing paint from dripping through the gap between the collection frame and the wall. A pressure rod is fixedly connected to the end of the compression spring away from the side plate, and a bonding plate is fixedly connected to the end of the pressure rod away from the compression spring. Force-bearing rods are symmetrically arranged at the end of the collection frame near the main rod, and this end is fixedly connected to the outer surface of the force-bearing rods. A rotating plate is fixedly connected to the end of the force-bearing rod away from the collection frame. Rubber tubes are symmetrically arranged on the top of the rotating plate, and the top of the rotating plate is fixedly connected to the bottom of the rubber tubes. A positioning rod is fixedly connected to the top of the rubber tubes. A discharge pipe is fixedly connected to the end of the collection frame near the main rod.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. This invention, by incorporating an adjustment component, allows control over the worker's stance when applying paint to a wall, thereby preventing paint from dripping onto the worker. The adjustment component also controls the angle between the main and auxiliary poles, ensuring the worker is not positioned below the paint application component, thus preventing paint drips onto the worker. Furthermore, the adjustment component controls the contact force between the paint application component and the wall, effectively controlling the depth of application. Moreover, the adjustment component prevents damage to the main pole when controlling the contact force between the paint application component and the wall.

[0013] 2. This invention, by incorporating a coating component, ensures that no paint drips during wall coating, thus preventing subsequent cleaning. An air pump on the coating component draws paint from the distribution pipe through the connecting pipe and then evenly distributes it onto the coating roller via the inner pipe, ensuring uniform coating of the wall surface. Furthermore, because the paint permeates from the inside of the coating roller to the outside, the probability of paint dripping is reduced. Additionally, the coating component includes a scraping element, which cleans away any fibrous material encountered during coating, preventing it from adhering to the coating roller and affecting subsequent coating results.

[0014] 3. This invention, by setting a turning plate, can control the angle between the secondary rod and the main rod. When the operator uses the applicator, as the applicator contacts the wall, pulling the secondary rod changes the angle between the secondary rod and the main rod. This causes the outer ring to move the turning plate, which in turn presses the connecting plate downwards. The connecting plate then compresses the compression spring, causing the compression spring to contract and deform. This causes the top of the guide rod on the retaining ring to enter the limiting cylinder, further changing the angle between the main rod and the secondary rod. The pressure exerted by the connecting plate on the compression spring ensures the adhesion between the applicator and the wall.

[0015] 4. By incorporating a scraping component, this invention reduces the amount of fibrous material adhering to the paint roller, thus preventing excessive fibrous material from affecting the painting effect when applying paint to walls. During use, the height of the cover plate is controlled by a telescopic rod, and the placement angle of the cover plate is controlled by a rotating disc. The scraping component cleans the fibrous material through the protrusions. When too much fibrous material remains in the gaps between the protrusions, rotating the rotating rod within the limiting frame causes multiple collection discs on the surface of the rotating rod to pull the fibrous material out of the gaps, thereby reducing the amount of fibrous material mixed in the gaps.

[0016] 5. This invention, by incorporating a collection component, can collect paint dripping from the paint roller during use into a collection frame, thereby preventing paint from dripping onto workers or the ground and affecting subsequent cleaning. When the painting component is in use, the positioning rod and rotating plate rotate relative to each other, ensuring that the collection frame is always positioned below the paint roller. The collection frame is then brought into contact with the wall, causing the bonding plate on one side of the collection frame to adhere to the wall, preventing paint from dripping through the gap between the collection frame and the wall. Furthermore, the inclined plate inside the collection frame can shorten the flow path of the paint, preventing excessive paint from adhering to the collection frame. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0027] Example 1, using Figures 1-8The following describes a self-priming waterproof coating applicator for building construction according to one embodiment of the present invention.

[0028] like Figures 1-8 As shown, the self-priming waterproof coating applicator for building construction of the present invention includes an applicator 1, a main rod 2 rotatably connected to the outer surface of the applicator, an adjusting component 3 fixedly connected to the outer surface of the main rod 2, and a connecting pipe 4 provided inside the main rod 2, with the outer surface of the connecting pipe 4 in contact with the inner wall of the main rod 2.

[0029] When the self-priming waterproof coating applicator for this type of building construction is put into use, the angle between the main rod 2 and the auxiliary rod 31 is first controlled by the adjusting component 3, so that the worker is not below the applicator 1. The applicator 1 is then brought into contact with the wall surface to apply the coating.

[0030] The coating component 1 is installed at the end of the main rod 2 away from the adjusting component 3. By setting the coating component 1, it is ensured that no paint drips when coating the wall, thus affecting subsequent cleaning work. The coating component 1 includes a frame 11, and an air pump 16 is installed inside the frame 11. The inner wall of the frame 11 is fixedly connected to the outer surface of the air pump 16. The outer surface of the air pump 16 is symmetrically provided with diversion pipes 12. The air pump 16 on the coating component 1 can draw the paint in the connecting pipe 4 from the diversion pipes 12, and then evenly distribute it on the brush roller 18 through the inner pipe 17, so that the brush roller 18 can evenly apply the paint to the wall surface. The outer surface of the air pump 16 is fixedly connected to the inner wall of the diversion pipe 12. The end of the diverter pipe 12 away from the air pump 16 is rotatably connected to the inner pipe 17. The outer surface of the inner pipe 17 is fixedly connected to the coating roller 18. The outer surface of the frame 11 is fixedly connected to the connecting frame 13. The connecting frame 13 is symmetrically arranged with support rods 14 inside. Since the paint penetrates from the inside of the coating roller 18 to the outside, the probability of the coating roller 18 dripping paint is reduced. Since the coating component 1 is provided with a scraping component 19, when the coating component 1 encounters flocculent matter during coating, it can be cleaned by the scraping component 19 to prevent it from adhering to the coating roller 18 and affecting its subsequent coating effect. The inner wall of the connecting frame 13 is rotatably connected to the outer surface of the support rod 14. The end of the support rod 14 away from the connecting frame 13 is fixedly connected to the insertion post 15.

[0031] When the coating component 1 is in use, the paint is connected to the connecting pipe 4 inside the main rod 2. Then, the paint is drawn from the connecting pipe 4 by the air pump 16 and transferred to the inner pipe 17 through the diverter pipe 12. The paint is then evenly distributed onto the coating roller 18 through the inner pipe 17 for coating the wall surface. When the coating roller 18 is coating the wall surface, the scraping component 19 can reduce the content of flocculent material adhering to the coating roller 18. When the coating roller 18 is in use, the collecting component 20 collects the dripping paint.

[0032] Adjustment component 3, installed on the outer surface of main rod 2, controls the worker's position when applying paint to the wall, preventing paint from dripping onto the worker. Adjustment component 3 includes a secondary rod 31, with a fixed plate 39 sleeved on its outer surface. An outer ring 40 is fixedly connected to the outer surface of the fixed plate 39, and a turning plate 32 is rotatably connected to the bottom of the outer ring 40. The turning plate 32 controls the angle between the secondary rod 31 and main rod 2. When the worker uses the painting component 1, the angle between the secondary rod 31 and main rod 2 changes as the painting component 1 contacts the wall. This causes the outer ring 40 to move the turning plate 32, resulting in the connecting plate 37 pressing downwards and compressing the compression spring 36. A collar 33 is rotatably connected to the end of the turning plate 32 away from the outer ring 40. Adjustment component 3 adjusts the angle between the main rod 2 and secondary rod 31, allowing the painting component 1 to adjust its position on the wall. When applying the coating, the worker will not be below the coating component 1, thus preventing paint from dripping onto the worker's body. A connecting plate 37 is fixedly connected to the end of the auxiliary rod 31 near the coating component 1. A compression spring 36 is fixedly connected to the bottom of the connecting plate 37. After being compressed by the connecting plate 37, the compression spring 36 begins to contract and deform, causing the top of the guide rod 35 on the retaining ring 34 to enter the limiting cylinder 38. This causes the angle between the main rod 2 and the auxiliary rod 31 to change. The pressure of the connecting plate 37 on the compression spring 36 ensures the adhesion between the coating component 1 and the wall. A retaining ring 34 is fixedly connected to the bottom of the compression spring 36. The contact force between the coating component 1 and the wall can be controlled by the adjusting component 3, thus effectively controlling the coating depth of the coating component 1. When the worker controls the contact force between the coating component 1 and the wall by adjusting the component 3, it will not cause damage to the main rod 2. A guide rod 35 is fixedly connected to the top of the retaining ring 34, and a limiting cylinder 38 is fixedly connected to the top of the connecting plate 37.

[0033] When the adjusting component 3 is in use, the coating component 1 contacts the wall, and then the auxiliary rod 31 is pulled, causing the outer ring 40 to move the turning plate 32, which in turn causes the included angle between the main rod 2 and the auxiliary rod 31 to change. During the pulling process, the connecting plate 37 compresses the compression spring 36, causing the compression spring 36 to contract and deform, resulting in the top area of ​​the guide rod 35 entering the limiting cylinder 38.

[0034] There are two diversion tubes 12, which are located inside the frame 11. There are two insertion posts 15, and the outer surface of the insertion post 15 is rotatably connected to the inner wall of the main rod 2. The connecting tube 4 is located inside the main rod 2, and the end of the connecting tube 4 near the coating component 1 is fixedly connected to the surface of the air pump 16. The top of the frame 11 is fixedly connected to the scraping component 19, and the bottom of the frame 11 is fixedly connected to the collecting component 20.

[0035] Example 2, using Figures 1-8 The following describes a self-priming waterproof coating applicator for building construction according to one embodiment of the present invention.

[0036] like Figures 1-8 As shown, the self-priming waterproof coating applicator for building construction of the present invention, based on Embodiment 1, includes a scraping component 19 comprising a cover plate 194. By setting the scraping component 19, the content of flocculent material adhering to the brush roller 18 can be reduced, thereby preventing the brush roller 18 from being affected by excessive flocculent material adhering to its surface when applying coating to the wall, thus improving its coating effect. Rotating disks 191 are symmetrically arranged at both ends of the cover plate 194, and the two ends of the cover plate 194 are rotatably connected to the opposite sides of the rotating disks 191. A telescopic rod 196 is fixedly connected to the bottom of the rotating disks 191. When the brush roller 18 is in use, the height of the cover plate 194 is controlled by the telescopic rod 196, and then the placement angle of the cover plate 194 is controlled by the rotating disks 191, so that the scraping component 19 cleans the flocculent material through the protrusions 195. The bottom of the cover plate 194 is uniformly provided with protrusions 195, and the bottom of the cover plate 194 is fixedly connected to the outer surface of the protrusions 195. The bottom of the cover plate 194 is uniformly provided with a limiting frame 197, and the bottom of the cover plate 194 is fixedly connected to the outer surface of the limiting frame 197. The limiting frame 197 is provided with a rotating rod 193 inside, and the inner wall of the limiting frame 197 is rotatably connected to the outer surface of the rotating rod 193. When too much flocculent material is retained in the gap of the protrusions 195, the rotating rod 193 inside the limiting frame 197 is rotated, so that multiple collection plates 192 provided on the surface of the rotating rod 193 pull the flocculent material out from the gap of the protrusions 195, thereby reducing the content of flocculent material mixed in the gap of the protrusions 195. The outer surface of the rotating rod 193 is uniformly provided with collection plates 192, and the outer surface of the rotating rod 193 is fixedly connected to the inner wall of the collection plate 192.

[0037] When the scraping component 19 is put into use, the height and placement angle of the cover plate 194 are controlled by the telescopic rod 196 and the rotating disk 191, so that the cover plate 194 contacts the surface of the coating roller 18. When the coating roller 18 rolls, the protrusions 195 on the cover plate 194 clean the lint adhering to the surface of the coating roller 18. Then, the rotating rod 193 on the limit frame 197 is rotated, and the collection disk 192 cleans the lint in the gap between the protrusions 195, ensuring the efficiency of the bottom protrusions 195 of the cover plate 194 in cleaning lint.

[0038] There are two telescopic rods 196, and the bottom of the telescopic rods 196 is fixedly connected to the inner wall of the frame 11. The collar 33 is located below the auxiliary rod 31, and the inner wall of the collar 33 is fixedly connected to the outer surface of the main rod 2. The axis of the coating roller 18 is on the same horizontal plane as the axis of the frame 11, and both ends of the coating roller 18 are rotatably connected to the inner wall of the frame 11.

[0039] The collecting component 20 includes a collecting frame 211. By setting the collecting component 20, paint dripping from the brush roller 18 during use can be collected into the collecting frame 211, thereby preventing paint from dripping during application and thus dripping onto workers or the ground, affecting subsequent cleaning work. Inclined plates 210 are symmetrically arranged inside the collecting frame 211. These inclined plates 210 shorten the paint flow path, preventing excessive paint adhesion inside the collecting frame 211. The inner wall of the collecting frame 211 is fixedly connected to the bottom of the inclined plates 210. Side plates 206 are symmetrically arranged at both ends of the collecting frame 211. The outer surface of the side plates 206 is fixedly connected to both ends of the collecting frame 211. A compression spring 207 is installed inside the side plates 206, and the outer surface of the compression spring 207 is fixedly connected to the inner wall of the side plates 206. When the application component 1 is in use, the positioning rod 202 and the rotating plate 204 rotate relative to each other, causing the collecting frame to... 211 is always located below the brush roller 18. Then, the collection frame 211 is brought into contact with the wall, so that the bonding plate 209 on one side of the collection frame 211 is in contact with the wall, preventing paint from dripping from the gap between the collection frame 211 and the wall. The end of the compression spring 207 away from the side plate 206 is fixedly connected to the extrusion rod 208. The end of the extrusion rod 208 away from the compression spring 207 is fixedly connected to the bonding plate 209. The end of the collection frame 211 near the main rod 2 is symmetrically provided with force rods 205, and the end of the collection frame 211 near the main rod 2 is fixedly connected to the outer surface of the force rod 205. The end of the force rod 205 away from the collection frame 211 is fixedly connected to the rotating plate 204. The top of the rotating plate 204 is symmetrically provided with rubber tubes 203. The top of the rotating plate 204 is fixedly connected to the bottom of the rubber tubes 203. The top of the rubber tubes 203 is fixedly connected to the positioning rod 202. The end of the collection frame 211 near the main rod 2 is fixedly connected to the discharge pipe 201.

[0040] When the collection component 20 is in use, the positioning rod 202 and the rotating plate 204 are used to control the placement angle of the collection frame 211, so that the collection frame 211 is placed below the paint roller 18. The bonding plate 209 set above the collection frame 211 is used to bond with the wall surface to prevent paint from dripping from the gap between the collection frame 211 and the wall surface. After the paint drips from the paint roller 18 into the collection frame 211, it is discharged from the discharge pipe 201 along the inclined plate 210. The paint is recycled and reused through the external pipe of the discharge pipe 201.

[0041] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
