Description

Technical Field

[0001] This utility model relates to the field of building construction coating technology, and more specifically, to a thickness-controllable scraper for coating application. Background Technology

[0002] With the development of building energy-saving technologies, the proportion of ultra-low energy consumption and near-zero energy consumption buildings in new construction is constantly increasing, placing higher demands on the overall thermal insulation performance of buildings. Exterior walls typically require a combination of internal and external insulation to meet these requirements, and the control of insulation layer thickness is becoming more stringent. When using inorganic thermal insulation mortar, FTC phase change thermal insulation mortar, and other thermal insulation coatings, applying the coating with a regular scraper relies heavily on the operator's experience, making it difficult to control the coating thickness and quality. This necessitates repeated repairs, resulting in low construction efficiency.

[0003] Patent CN218815015U discloses a scraper for applying waterproof coating. By rotating a worm gear in an adjusting mechanism, a matching worm wheel block rotates, causing a threaded screw fixedly connected to the worm wheel block to rotate, which in turn moves a movable support frame fixedly connected to a threaded moving plate. The movement of the movable support frame changes the distance between the scraper plate and the wall, thus adjusting the distance between the scraper and the wall. However, while the scraper can change the distance between the scraper plate and the wall through the adjusting mechanism, the adjustment method is relatively complex and lacks a clear limiting device for precise distance control, resulting in insufficient precision in controlling the coating thickness. Furthermore, its adjusting structure relies on a worm gear structure, which is complex. During the scraping process, coating may splash onto the worm gear and other structures, interfering with the adjustment process and making it prone to malfunction during use.

[0004] Therefore, a new type of paint scraper is needed to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a thickness-controllable scraper for coating.

[0006] A thickness-controllable scraper for coating, comprising a scraper body, wherein the scraper body is provided with a handle;

[0007] The scraper body has a slot on the side near the coating surface for engaging the scraper blade; a limiting component is movably connected to the side of the scraper body near the coating surface, and the distance the limiting component extends out of the scraper body from the coating surface is adjustable within a preset range.

[0008] Furthermore, the groove forms a 30° angle with the side of the scraper body near the coating surface, and extends along one end of the scraper body to the side, while the other end is closed.

[0009] Furthermore, the card slot is provided with a guide groove on its side, which serves as a discharge channel for excess material on the surface during the scraping operation.

[0010] Furthermore, the scraper has raised portions on the edge of its back that fit into the slot.

[0011] Furthermore, the limiting component is located at the end of the scraper body and is used to adjust the distance between the scraper and the scraping surface; the limiting component includes a fixing block and a limiting clip, the fixing block is movably connected to one side of the scraping surface of the scraper body and can be embedded in the scraper body or extend out of the scraper body by a preset distance; when the fixing block extends out of the scraper body by a preset distance, the limiting clip is engaged with the fixing block.

[0012] Furthermore, a receiving groove is provided on the side of the scraper body near the scraping surface, and the fixing block is connected to the inner wall of the receiving groove by a spring. One end of the spring is fixed to the rear side wall of the fixing block, and the other end is fixed to the inner wall of the receiving groove.

[0013] Furthermore, one end of the limiting clip is rotatably connected to the side of the receiving groove.

[0014] Furthermore, two limiting clips are provided, located on both sides of the receiving groove respectively.

[0015] Furthermore, the outer side of the fixing block is provided with a number of limiting slots; at least two limiting slots are provided at a predetermined distance from the front sidewall of the fixing block.

[0016] Furthermore, limiting slots are provided at thicknesses of 5mm, 10mm, 15mm, and 20mm on the outer side of the fixing block.

[0017] Furthermore, after the two limiting clips are rotated, they respectively engage with the two limiting slots at the same preset distance from the front sidewall of the fixed block.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This thickness-controllable scraper for paint application uses a limiting component that controls the distance between the scraper and the painting surface through the extension distance of the fixed block and the engagement position of the limiting clip, thereby achieving precise adjustment of the paint application thickness. The fixed block has clearly defined limiting slots of 5mm, 10mm, 15mm, and 20mm on its side, allowing for quick and accurate selection of the corresponding limiting slot 1 for engagement according to actual needs. This avoids uneven paint thickness caused by inaccurate adjustment, improves construction quality, and offers a simple and intuitive operation.

[0020] Furthermore, the scraper blade features a raised portion at its back edge that mates with the groove, effectively preventing the blade from detaching from the side facing the coating surface. Simultaneously, the groove's 30° angle with the scraper body further enhances the blade's stability. This ensures greater stability during coating, preventing loosening or detachment due to external forces, thus guaranteeing the continuity and stability of the coating application process and improving construction efficiency and quality.

[0021] Furthermore, the limiting component has a relatively simple structure, mainly consisting of a fixing block and a limiting clip, and is connected to the inner wall of the receiving groove by a spring. It is easier to clean and maintain during use, and even if a malfunction occurs, repair and replacement are relatively simple and quick, reducing the maintenance cost and repair time of the tool, and improving its service life and reliability.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-3 As shown, this embodiment provides a thickness-controllable scraper for coating, including a scraper body 1. A handle 11 is provided on the side of the scraper body 1 away from the coating surface for easy gripping and coating operations. A groove 12 is provided along the length of the scraper body 1 near the coating surface for engaging a scraper blade 2. A limiting component 3 is movably connected to the side of the scraper body 1 near the coating surface. The distance the limiting component 3 extends from the scraper body 1 near the coating surface is adjustable, thereby enabling control of the coating thickness.

[0033] In this embodiment, the groove 12 of the scraper body 1 forms a 30° angle with the side of the scraper body 1 closest to the coating surface, and extends through one end of the scraper body 1 along its side, while the other end is closed. The scraper blade 2 has a protruding portion 21 on its blade back edge, which matches the groove 12, meaning the scraper blade 2 fits tightly against its corresponding groove 12. When the scraper blade 2 is installed into the groove 12 along its open end, the protruding design of the blade back prevents it from falling off along the side facing the coating surface. The protruding portion 21 on the blade back edge of the scraper blade 2, which matches the groove 12, effectively prevents the scraper blade 2 from falling off along the side facing the coating surface, improving the stability of the scraper blade. Simultaneously, the 30° angle between the groove 12 and the scraper body 1 further enhances the stability of the scraper blade.

[0034] A guide groove 13 is provided on the side of the slot 12 for unloading excess material on the surface during the scraping operation. This design can effectively solve the problem of handling excess paint, allowing the excess material to be discharged smoothly and avoiding residue on the surface of the scraper or scraper. It can reduce the uneven scraping caused by the accumulation of excess material, reduce the workload of construction workers in cleaning up excess material, and make the construction process smoother.

[0035] In this embodiment, the limiting component 3 is located at the end of the scraper body 1 and is used to adjust the distance between the scraper 2 and the coating surface. The limiting component 3 includes a fixing block 31 and a limiting clip 32. The fixing block 31 is movably connected to the side of the scraper body 1 near the coating surface and can be embedded in the scraper body 1 or extend out of the scraper body 1 by a preset distance. When the fixing block 31 extends out of the scraper body 1 by a preset distance, the limiting clip 32 engages with the fixing block 31. A limiting groove 311 is provided on the side of the limiting block 31 at a thickness of 5mm, 10mm, 15mm, and 20mm.

[0036] Specifically, a receiving groove 14 is provided on the side of the scraper body 1 near the scraping surface, that is, a receiving groove 14 is provided at the bottom of the scraper body 1. The fixing block 31 is connected to the inner wall of the receiving groove 14 by a spring 4. One end of the spring 4 is fixed to the rear side wall of the fixing block 31, and the other end is fixed to the inner wall of the receiving groove 14. When the limiting component 3 is not used for limiting, the fixing block 31 is embedded in the receiving groove 14. When it is necessary to use the limiting component 3 to adjust the scraping thickness, the limiting clip 32 is engaged with the corresponding limiting clip slot 311.

[0037] More specifically, one end of the limiting clip 32 is rotatably connected to the side of the receiving groove 14 on the scraper body 1, meaning the limiting clip 32 is movably connected to the scraper body 1 and can rotate around a fixed point. The limiting clip 32 engages with the two limiting grooves 311 at the same thickness as the fixed block 31 by twisting, thus limiting the coating thickness. Since the limiting grooves 311 are provided on the side of the limiting block 31 at thicknesses of 5mm, 10mm, 15mm, and 20mm, the coating thickness can be precisely adjusted by the extension distance of the fixed block 31 and the engagement position of the limiting clip 32.

[0038] More specifically, two limiting clips 32 are provided, located on both sides of the receiving groove 14. Several limiting slots 311 are formed on the outer surface of the fixing block 31; at least two limiting slots 311 are provided at a predetermined distance from the front sidewall of the fixing block 31. After rotation, the two limiting clips 32 respectively engage with the two limiting slots 311 at the same predetermined distance from the front sidewall of the fixing block 31.

[0039] like Figure 4 As shown, when using this scraper for wall paint application, adjust the extension length of the fixing block 31 according to the coating thickness, and move the limiting clip 32 to the corresponding thickness-sized limiting groove 311 of the fixing block 31 to achieve engagement. Insert the scraper 2 into the scraper body along the groove 12 to perform the scraping operation. During use, slide the side of the fixing block 31 closest to the scraping surface flat against the wall surface 5, driving the scraper 2 to scrape off excess paint from the wall. After use, first open the limiting clip 32, press the fixing block 31 into the receiving groove 14, then pull the limiting clip 32 back so that the limiting clip 32 abuts against the side of the fixing block 31 closest to the scraping surface, preventing the fixing block 31 from popping out, and finally remove the scraper 2.

[0040] The thickness-controllable scraper for paint application provided in this embodiment uses a limiting component 3 to control the distance between the scraper 2 and the surface being scraped by adjusting the extension distance of the fixed block 31 and the engagement position of the limiting clip 32, thereby achieving precise adjustment of the paint application thickness. The fixed block 31 has clearly defined limiting slots 311 on its side, such as 5mm, 10mm, 15mm, and 20mm. Operators can quickly and accurately select the corresponding limiting slot 311 for engagement according to actual needs, avoiding uneven paint thickness caused by inaccurate adjustment and improving construction quality. Operators only need to adjust the extension length of the fixed block 31 according to the required coating thickness and move the limiting clip 32 to the corresponding thickness-sized limiting slot 311 of the fixed block 31 to achieve engagement, thus completing the adjustment of the paint application thickness. This operation method is simple, intuitive, and easy to master, requiring no complex mechanical operations, reducing the skill requirements for construction personnel, improving construction efficiency, and also reducing the risk of tool damage due to improper operation.

[0041] The scraper blade 2 has a raised portion 21 on its back edge, which fits into the groove 12. This design effectively prevents the scraper blade 2 from falling off along the side facing the coating surface. Simultaneously, the groove 12 forms a 30° angle with the scraper body 1, further enhancing the scraper blade's stability. The scraper blade 2 is more stable during the coating process and will not loosen or fall off due to external forces, thus ensuring the continuity and stability of the paint coating operation and improving construction efficiency and quality.

[0042] The structure of the limiting component 3 is relatively simple, mainly consisting of a fixing block 31 and a limiting clip 32. It is connected to the inner wall of the receiving groove 14 through a spring 4. It is easier to clean and maintain during use. Even if a fault occurs, repair and replacement are relatively simple and quick, reducing the maintenance cost and repair time of the tool and improving its service life and reliability.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
