Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and more specifically, to a scraper. Background Technology

[0002] As a common handheld cleaning tool, scrapers are widely used to remove paint, glue residue, frost, and other residues from object surfaces. Most scrapers on the market currently use a fixed structure, meaning the blade is rigidly connected to the handle, and its scraping width remains constant. While some products offer blade replacement or retractable storage, these are only for maintenance or safety purposes and do not change their single working mode.

[0003] However, when encountering cleaning areas of different sizes, users must prepare multiple sizes of scrapers to switch between, which not only increases purchase costs but also affects operational efficiency. Furthermore, fixed blades cannot handle diverse scenarios such as large-area scraping and cleaning narrow corners, resulting in a severe lack of flexibility. Therefore, there is an urgent need for a multi-functional scraper solution that can adapt to different working conditions. Utility Model Content

[0004] The purpose of this utility model is to provide a scraper that enables a single blade to quickly switch between two different scraping width working modes, thereby effectively solving the problems of traditional scrapers having limited functionality and application range.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] The following describes in detail the overall structure, working principle, and technical effects of the shovel provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0026] Please refer to Figures 1-3 The scraper 100 provided by this utility model is used for cleaning the surface of objects, specifically for scraping off paint, glue stains, labels, oil stains, frost and other residues attached to hard, flat surfaces such as glass, tiles, metal, and plastic.

[0027] The scraper 100 includes a housing 10 and a blade 20. The housing 10 has a cavity with an opening 11 communicating with it. Exemplarily, the blade 20 may be rectangular. The width of the blade 20 is adapted to the cavity. It is understood that the blade 20 is detachably connected to the housing 10. By setting the width of the blade 20 to adapt to the cavity, one side of the wider side of the blade 20 can enter the cavity through the opening 11, while the other wider side of the blade 20 extends beyond the housing 10. Cutting edges 21 are provided on the long and wide sides of the blade 20. Further, a first mating portion 22 is provided on one of the long sides of the blade 20, and a second mating portion 12 is provided at the opening 11. The blade 20 can be selectively housed in the cavity so that the wide edge 21 of the blade 20 faces the outside of the housing 10, or it can be detachably fixed to the opening 11 by the first mating part 22 and the second mating part 12 so that the long edge 21 of the blade 20 faces the outside of the housing 10.

[0028] It is understandable that when the blade 20 enters the cavity, the wide edge of one side of the blade 20 extends outside the housing 10, which is the narrow scraping working mode, using the cutting edge 21 of the wide edge of the blade 20 for scraping. When it is necessary to switch to the wide scraping working mode, the blade 20 is removed, and the long side of the blade 20 with the first mating part 22 is engaged with the first mating part of the opening 11 to fix the blade 20 at the opening 11, so that the cutting edge 21 of the long edge of the blade 20 faces outside the housing 10, which is the wide scraping working mode, using the cutting edge 21 of the long edge of the blade 20 for scraping. The scraper 100 of this embodiment realizes convenient switching between narrow and wide scraping modes with a single tool through the above structure, and can select different blade widths 21 according to different working conditions, significantly improving the adaptability of scraping operations.

[0029] Specifically, the first mating part 22 consists of two slotted grooves spaced apart on the long side of the blade 20. The second mating part 12 consists of two sidewalls at the opening 11. The sidewalls engage with the slotted grooves so that the long-side cutting edge 21 of the blade 20 faces outward. Through the engagement of the sidewalls with the slotted grooves, the blade 20 can be reliably locked at the opening 11, thereby ensuring that the cutting edge 21 on the long side of the blade 20 not where the first mating part 22 is located faces stably outward, thus enabling the wide scraping operation.

[0030] In this embodiment, the blade 20 has a cutting edge 21 on both wide sides. One long side of the blade 20 has a cutting edge 21, and the other long side has a first mating part 22. It is understood that by providing cutting edges 21 on both wide sides of the blade 20, regardless of whether the blade 20 is inserted into the cavity from the front or back, the end of the blade 20 located outside the housing 10 always has a usable cutting edge 21, thus avoiding the problem of inability to scrape properly due to incorrect insertion direction, and improving the error tolerance and convenience of operation. By providing a cutting edge 21 on one long side of the blade 20 and not providing a cutting edge 21 on the other long side where the first mating part 22 is located, the user can hold the unsharpened long side when inserting or removing the blade 20. This structure effectively avoids the risk of being cut by the cutting edge 21 during hand operation, improving operational safety and convenience.

[0031] Furthermore, the cutting edge 21 on the wide side of the blade 20 is shorter than the width of the blade 20 and is centered along the wide side. Similarly, the cutting edge 21 on the long side of the blade 20 is also shorter than the length of the long side and is centered along the long side. Understandably, the cutting edges 21 do not extend to the corners of the blade 20, preserving the material integrity of the blade's base and effectively preventing stress concentration at the corners that could lead to chipping or rolling, thus improving the strength and service life of the blade 20.

[0032] Furthermore, the four corners of the blade 20 are rounded 23. It is understood that in this embodiment, the portions of the blade 21 that do not extend into the blade 20 are rounded 23. This effectively eliminates the sharp edges of the blade 20, reducing the risk of the blade 20 scratching the user or damaging other items during installation and removal. Simultaneously, the rounded 23 structure allows the blade 20 to smoothly insert into or withdraw from the cavity of the housing 10, improving the portability of the scraper 100 mode switching.

[0033] Specifically, in this embodiment, the blade 21 has a single-sided cutting structure, including a cutting surface 211 inclined relative to the surface of the blade 20 and a back surface 212 flush with the surface of the blade 20. It is understood that by providing the back surface 212 flush with the lower surface of the blade 20, it can conform to the substrate surface during scraping, providing support and guidance. This effectively prevents the blade 20 from excessively cutting and scratching the substrate, while also ensuring the smoothness of the surface after scraping. The inclined cutting surface 211 facilitates cutting into and lifting residue, and together with the flush back surface 212, significantly reduces the propulsion resistance during scraping, making operation less strenuous and control more precise and stable.

[0034] Specifically, in this embodiment, the scraper 100 also includes a cover 30. The cover 30 is detachably disposed over the opening 11 to close the cavity. It is understood that by providing the cover 30, the blade 20 can be hidden between the housing 10 and the cover 30 when the scraper 100 is not in use, thus preventing injury to the user or damage to other items.

[0035] To facilitate the fixing of the cover 30, a rib 13 is provided on the side wall of the opening 11. When the cover 30 is placed over the opening 11, the rib 13 abuts against the inner wall of the cover 30. It can be understood that the external dimensions of the rib 13 are slightly larger than the inner wall dimensions of the cover 30, and the rib 13 is an elastic structure that can undergo a certain degree of deformation, so that the rib 13 and the cover 30 are interference-fitted, thereby fixing the cover 30 and the shell 10.

[0036] Furthermore, a through hole 15 is provided at the end of the housing 10 away from the opening 11. Understandably, the through hole 15 is for a rope to pass through, so that the shovel 100 can be hung on the frame, hook or wrist for easy access and to improve the convenience of carrying and storing.

[0037] In this embodiment, the outer surface of the housing 10 is also provided with anti-slip texture 14. By providing anti-slip texture 14, the friction between the hand and the surface of the housing 10 is increased, effectively preventing the tool from slipping or falling out of the hand when wet, oily, or when scraping forcefully, thereby improving the stability and safety of operation and reducing the risk of accidents.

[0038] The beneficial effects of the shovel 100 provided in this embodiment of the utility model include: The shovel 100 provided by this utility model includes a housing 10 and a blade 20. The housing 10 has a cavity and an opening 11 communicating with the cavity on one side. The blade 20 is rectangular. The width of the blade 20 is adapted to the cavity. A cutting edge 21 is provided on both the long and wide sides of the blade 20. A first mating part 22 is provided on one of the long sides of the blade 20, and a second mating part 12 is provided at the opening 11. The blade 20 can be selectively housed within the cavity with the wide cutting edge 21 facing outwards from the housing 10, or it can be detachably fixed to the opening 11 through the engagement of the first mating part 22 and the second mating part 12, with the long cutting edge 21 facing outwards from the housing 10. By setting blades 21 of different lengths on the long and wide sides of the blade 20, when the blade 20 is stored in the cavity, the wide blade 21 faces outward, and at this time, the wide blade 21 performs scraping work. By removing the blade 20 from the cavity, the first mating part 22 of the long side engages and fixes with the second mating part 12 of the opening 11, fixing the blade 20 at the opening 11, so that the blade 21 of the other long side of the blade 20 faces outward, and at this time, the long blade 21 performs scraping work. This utility model enables a single blade 20 to quickly switch between two different scraping width working modes, and can take into account both large-area scraping and narrow corner cleaning, thereby solving the problem of the traditional scraper 100 having a single function and limited scope of application.

[0039] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
