Description

Technical Field

[0001] This utility model relates to the field of scrapers, and in particular to a scraper for applying putty. Background Technology

[0002] A putty scraper is a tool used when applying putty to walls. It is mainly used to spread putty powder evenly on the wall surface to achieve a smoothing effect.

[0003] Traditional putty brushes have a relatively fixed design, usually being a single piece. This means that once the brush wears out or is damaged, the entire brush needs to be replaced, which not only increases costs but also wastes resources. Furthermore, the handle angle is fixed and cannot be adjusted to meet specific construction needs, limiting the brush's flexibility and applicability in different working environments.

[0004] Therefore, those skilled in the art have provided a putty scraper to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a putty scraper. This putty scraper features a groove designed on the scraper blade, with a locking groove within the groove. A locking block is mounted on the base plate, connected to a spring within a limiting groove. This ensures the locking block fits tightly against the inner wall of the limiting groove. The operator simply pulls on both sides to press the locking block against the inner wall of the limiting groove, then pushes the base plate to slide within the groove. When the designated position is reached, the locking block automatically pops out and fits tightly against the locking groove, achieving a secure limiting effect. Finally, tightening the first bolt, which penetrates the base plate and presses against the locking block, further enhances the stability and reliability of the limiting mechanism. This design employs a sliding connection method and a locking mechanism... The combination of components such as the groove enables quick scraper replacement, improving work efficiency. The scraper has a No. 1 gear and a No. 2 gear on the handle, which mesh with each other. During use, simply push the movable block to one side to disengage the No. 1 gear from the No. 2 gear, thus rotating the movable block. After adjusting to a suitable construction angle, simply pull the movable block to the other side, and the No. 1 gear will re-engage with the No. 2 gear, achieving tight meshing and completing the limit. The No. 3 bolt passes through the movable block and tightens against the No. 2 gear, further ensuring the stability of the limit and making the entire limit structure more robust. When constructing on different parts such as walls or ceilings, the adjustable handle can adapt to different construction angles, making operation more flexible and improving construction efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A putty scraper includes a fixed rod and a scraper blade. The lower end of the fixed rod is fixedly connected to a base plate. The rear end of the upper surface of the base plate is fixedly connected to a mounting plate. A groove is formed on the rear part of the upper surface of the scraper blade. The inner wall of the groove has locking grooves on both sides of the front end. The outer wall of the base plate has limiting grooves on both sides of the front end. A first spring is fixedly connected to the middle of the adjacent sides of the inner wall of the limiting groove. A locking block is fixedly connected to the side of the first spring away from the base plate. A pull tab is fixedly connected to the upper surface of the locking block away from the base plate. A first bolt is threaded to both sides of the front part of the upper surface of the scraper blade close to the groove. A second bolt is threaded to both sides of the upper surface of the mounting plate.

[0008] Through the above technical solution, this putty painting scraper features a groove designed on the scraper blade, with a snap-fit ​​groove inside the groove. A snap-fit ​​block is installed on the base plate, connected to a spring within a limiting groove. This ensures the snap-fit ​​block fits tightly against the inner wall of the limiting groove. The operator simply pulls the tabs on both sides to make the snap-fit ​​block press against the inner wall of the limiting groove, then pushes the base plate to slide in the groove. When it reaches the designated position, the snap-fit ​​block automatically pops out and fits tightly against the snap-fit ​​groove, achieving a secure limiting effect. Finally, tightening the bolt (number one) through the base plate and pressing it against the snap-fit ​​block further enhances the stability and reliability of the limiting effect. The sliding connection method, along with the cooperation of components such as the snap-fit ​​groove, enables quick scraper replacement. The blade's function improves work efficiency. The scraper has a first gear and a second gear on the handle, which mesh with each other. During use, simply push the movable block to one side to disengage the first gear and the second gear, thus rotating the movable block. After adjusting to a suitable construction angle, simply pull the movable block to the other side, and the first gear will re-engage with the second gear, achieving tight meshing and completing the limit. The third bolt passes through the movable block and tightens against the second gear, further ensuring the stability of the limit and making the entire limit structure more robust. When constructing on different parts such as walls or ceilings, the adjustable handle can adapt to different construction angles, making operation more flexible and improving construction efficiency.

[0009] Furthermore, the base plate is slidably connected to the groove;

[0010] Through the above technical solution, the sliding connection between the base plate and the slide groove, combined with the design of the snap-fit ​​block and the limiting groove, enables the quick replacement function of the scraper.

[0011] Furthermore, the snap-fit ​​block is slidably connected to the snap-fit ​​slot;

[0012] With the above technical solution, since the locking block and locking groove are slidably connected, when the scraper needs to be installed, the operator only needs to align the scraper's groove with the locking block on the base plate, and then push the scraper so that the locking block slides along the locking groove until the locking block is fully inserted into the locking groove, thus achieving quick installation of the scraper. This design simplifies the installation steps, reduces installation time, and improves work efficiency.

[0013] Furthermore, the upper part of the outer wall of the movable block is fitted with an anti-slip soft sleeve;

[0014] Through the above technical solutions, the surface of the anti-slip soft sleeve usually has a certain texture or roughness, which can increase the friction between the hand and the moving block and prevent the hand from slipping during gripping. Especially when the hands are sweaty or have putty powder or other substances on them, the anti-slip soft sleeve can provide a better anti-slip effect, ensuring that the operator can hold the moving block stably and avoid loss of control of the scraper or construction errors caused by hand slippage.

[0015] Furthermore, the first gear and the second gear mesh with each other;

[0016] Through the above technical solution, the precise adjustment of the handle angle can be achieved by the meshing of gear one and gear two. The operator only needs to push or pull the movable block to rotate gear two, which in turn causes gear one to rotate synchronously, thus rotating the handle. This gear transmission method provides a stable transmission ratio and control, allowing the handle to be flexibly adjusted to a suitable angle for construction, adapting to the construction needs of different parts such as walls and ceilings.

[0017] Furthermore, the fixed column passes through the middle of the first gear and is fixedly connected to the movable block;

[0018] The above technical solution, by having a fixed column pass through the middle of the first gear and be fixedly connected to the movable block, ensures synchronous movement between the first gear and the movable block. When the movable block rotates or moves, the fixed column drives the first gear to rotate synchronously, thereby achieving precise transmission control. This design avoids potential relative slippage or asynchrony between the gear and the movable block, improving transmission efficiency and stability.

[0019] Furthermore, a protective cover is fixedly connected to the other side of the fixing plate, and the other side of the protective cover is fixedly connected to one side of the first gear.

[0020] Through the above technical solution, the protective cover can isolate the transmission components, such as the No. 1 gear, from the external environment, effectively preventing impurities such as dust and putty powder particles from entering the gear transmission system. If these impurities enter the gear gaps, they may cause accelerated gear wear, disrupted transmission, or even malfunction. The protective function of the cover helps keep the gear transmission system clean and extend its service life.

[0021] Furthermore, both ends of the other side of the outer wall of the movable block are threaded with No. 3 bolts;

[0022] Through the above technical solution, bolt No. 3 is threaded to both ends of the movable block, providing additional fixing points for the movable block. When the movable block needs to be fixed in a certain position, tighten bolt No. 3 to press it against the contact surface between the movable block and adjacent components, thereby increasing the fixing force and ensuring that the movable block will not loosen or shift during use, thus improving the stability of the equipment.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model proposes a putty brush scraper. The scraper features a groove on the scraper blade with a locking slot within it. A locking block is mounted on the base plate, connected to a spring within a limiting slot. This ensures the locking block fits tightly against the inner wall of the limiting slot. The operator simply pulls the tabs on both sides to press the locking block against the inner wall of the limiting slot, then pushes the base plate to slide within the groove. When the designated position is reached, the locking block automatically pops out and fits tightly against the locking slot, achieving a secure limiting effect. Finally, tightening the bolt (number one) penetrates the base plate and presses against the locking block further enhances the stability and reliability of the limiting effect. The sliding connection and the cooperation of components such as the locking slot enable quick scraper blade replacement, improving work efficiency.

[0025] 2. This utility model proposes a putty scraper with a first gear and a second gear on the handle. The two gears mesh with each other. In use, simply push the movable block to one side to separate the first gear from the second gear, thereby rotating the movable block. After adjusting to a suitable construction angle, simply pull the movable block to the other side, and the first gear will re-engage with the second gear, achieving tight meshing and completing the limiting position. A third bolt passes through the movable block and tightens against the second gear, further ensuring the stability of the limiting position and making the entire limiting structure more robust. When constructing on different parts such as walls or ceilings, the adjustable handle can adapt to different construction angles, making the operation more flexible and improving construction efficiency.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0035] A putty scraper includes a fixing rod 1 and a scraper 11. A base plate 2 is fixedly connected to the lower end of the fixing rod 1. A mounting plate 3 is fixedly connected to the rear end of the upper surface of the base plate 2. A groove 4 is formed on the rear part of the upper surface of the scraper 11. Engaging grooves 5 are formed on both sides of the front end of the inner wall of the groove 4. Limiting grooves 6 are formed on both sides of the front end of the outer wall of the base plate 2. A first spring 7 is fixedly connected to the middle of adjacent sides of the inner wall of the limiting groove 6. Engaging blocks 8 are fixedly connected to the side of the first spring 7 away from the base plate 2. Pull tabs 20 are fixedly connected to the upper surface of the engaging blocks 8 away from the base plate 2. The scraper 11 has two threaded bolts 9 on both sides of its upper surface near the groove 4, and the mounting plate 3 has two threaded bolts 10 on both sides of its upper surface. This putty brush scraper has a groove 4 designed on the scraper 11, and a snap-fit ​​groove 5 is opened in the groove 4. A snap-fit ​​block 8 is installed on the base plate 2, and the snap-fit ​​block 8 is connected to a spring 7 in the limiting groove 6, ensuring that the snap-fit ​​block 8 can fit tightly against the inner wall of the limiting groove 6. The operator only needs to pull the pull tabs 20 on both sides to make the snap-fit ​​block 8 fit tightly against the inner wall of the limiting groove 6, and then push the base plate 2 to slide in the groove 4. When the designated position is reached, the locking block 8 automatically pops out and fits tightly into the locking groove 5, achieving a secure limiting effect. Finally, by tightening the first bolt 9, it penetrates the base plate 2 and presses against the locking block 8, further enhancing the stability and reliability of the limiting. The sliding connection method, along with the cooperation of components such as the locking groove 5, enables quick replacement of the scraper 11, improving work efficiency. The scraper has a first gear 13 and a second gear 15 on the handle, which mesh with each other. During use, simply push the movable block 17 to one side to drive the first gear. 13 separates from gear 15, allowing the movable block 17 to rotate. After adjusting to a suitable construction angle, simply pull the movable block 17 to the other side, and gear 13 will re-engage with gear 15, achieving tight gear meshing and thus completing the limit. Bolt 21 passes through the movable block 17 and presses against gear 15, further ensuring the stability of the limit and making the entire limit structure more robust. When constructing on different parts such as walls or ceilings, the adjustable handle can adapt to different construction angles, making operation more flexible and improving construction efficiency.

[0036] Reference Figure 3-5The base plate 2 is slidably connected to the slide groove 4. This slidable connection, combined with the design of the snap-fit ​​block 8 and the limiting groove 6, enables the quick replacement of the scraper 11. The snap-fit ​​block 8 is slidably connected to the snap-fit ​​groove 5. Because the snap-fit ​​block 8 and the snap-fit ​​groove 5 are slidably connected, when the scraper 11 needs to be installed, the operator only needs to align the slide groove 4 of the scraper 11 with the snap-fit ​​block 8 on the base plate 2, and then push the scraper 11 so that the snap-fit ​​block 8 slides along the snap-fit ​​groove 5 until the snap-fit ​​block 8 is completely inserted into the snap-fit ​​groove 5, thus achieving quick installation of the scraper 11. This design simplifies the installation steps, reduces installation time, and improves work efficiency. The upper part of the outer wall of the movable block 17 is covered with an anti-slip soft sleeve 18. The surface of the anti-slip soft sleeve 18 usually has a certain texture or roughness, which can increase the friction between the hand and the movable block 17 and prevent the hand from slipping during gripping. Especially when hands are sweaty or covered with putty powder, the anti-slip soft sleeve 18 provides better anti-slip effect, ensuring that the operator can hold the movable block 17 stably and avoid loss of control of the scraper or construction errors due to slipping hands. Gear 13 and Gear 25 mesh with each other, allowing for precise adjustment of the handle angle. The operator only needs to push or pull the movable block 17 to rotate Gear 25, which in turn causes Gear 13 to rotate synchronously, thus rotating the handle. This gear transmission method provides a stable transmission ratio and control, allowing the handle to be flexibly adjusted to a suitable construction angle to adapt to the construction needs of different parts such as walls and ceilings. The fixed post 16 passes through the middle of Gear 13 and is fixedly connected to the movable block 17, ensuring synchronous movement between Gear 13 and the movable block 17. When the movable block 17 rotates or moves, the fixed column 16 drives the first gear 13 to rotate synchronously, thereby achieving precise transmission control. This design avoids possible relative slippage or asynchrony between the gear and the movable block 17, improving transmission efficiency and stability. A protective cover 19 is fixedly connected to the other side of the fixed plate 12, and the other side of the protective cover 19 is fixedly connected to one side of the first gear 13. The protective cover 19 can isolate the first gear 13 and other transmission components from the external environment, effectively preventing dust, putty powder particles and other impurities from entering the gear transmission system. If these impurities enter the gear gap, they may cause accelerated gear wear, poor transmission, or even malfunction. The protective function of the protective cover 19 helps to keep the gear transmission system clean and extend its service life. Both ends of the other side of the outer wall of the movable block 17 are threaded with No. 3 bolts 21, which provide additional fixing points for the movable block 17.When the movable block 17 needs to be fixed in a certain position, tighten the No. 3 bolt 21 to make it press against the contact surface between the movable block 17 and the adjacent parts, thereby increasing the fixing force and ensuring that the movable block 17 will not loosen or shift during use, thus improving the stability of the equipment.

[0037] Working principle: When using this putty brush scraper, first, pull the two pull tabs 20 on both sides to make the locking block 8 fit tightly against the inner wall of the limiting groove 6. Then, push the base plate 2 to slide in the sliding groove 4. When it reaches the designated position, the locking block 8 will automatically pop out and fit tightly against the locking groove 5, achieving a firm limiting effect. Finally, by tightening the No. 1 bolt 9, it passes through the base plate 2 and presses against the locking block 8, further enhancing the stability and reliability of the limiting. The sliding connection method, along with the cooperation of the locking groove 5 and other components, enables quick replacement of the scraper blade 11, improving work efficiency. It can also be pushed to one side as needed. Moving the movable block 17 will cause the first gear 13 to separate from the second gear 15, thereby enabling the movable block 17 to rotate. After adjusting to a suitable construction angle, simply pull the movable block 17 to the other side, and the first gear 13 will re-engage with the second gear 15, achieving tight gear meshing and thus completing the limit. The third bolt 21 passes through the movable block 17 and presses against the second gear 15, further ensuring the stability of the limit and making the entire limit structure more robust. When constructing on different parts such as walls or ceilings, the adjustable handle can adapt to different construction angles, making the operation more flexible and improving construction efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
