Description

Technical Field

[0001] This utility model relates to the field of scraper technology for application, and more particularly to an adjustable width scraper for applying adhesives. Background Technology

[0002] A scraper is a widely used tool in various application scenarios. It has a specific shaped scraper head and comes in various materials, such as plastic and metal, to accommodate different textures of application materials, such as face cream, face mask, paint and glue. Thanks to its design, it can evenly spread the application material on the target surface. Whether it is to help the skin better absorb products during skincare or to ensure the consistency of application results in industrial and handicraft production, it can play a key role. It not only improves application efficiency, but also allows for precise control of the amount used, reducing waste, and making the application work more efficient, convenient and precise.

[0003] Adjustable-width scrapers for adhesive application are practical tools specifically designed for adhesive application. Breaking away from traditional fixed-size limitations, they feature a unique, flexibly adjustable width structure. This allows for precise adjustment of the scraper's working width over a wide range to meet different construction needs. Made primarily of durable and corrosion-resistant metals or high-strength plastics, they ensure stability and reliability when in contact with various adhesives. This adjustable feature makes them highly effective in many fields involving adhesive application, such as construction, furniture manufacturing, and electronic component bonding. They adapt to diverse construction scenarios, ensuring even and appropriate application of adhesives, effectively improving construction quality, reducing material waste, and providing strong support for efficient adhesive application. While scrapers are suitable for applying adhesives to flat or regular surfaces, they are difficult to operate on complex shapes, textured surfaces, or confined spaces, making even application challenging. Current technology uses specialized applicator clamps to hold the object being applied, making the surface easier to handle. However, due to the wide application area, multiple applications are required, reducing work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable width scraper for applying adhesives, which aims to improve the problem in the prior art that multiple applications are required due to the wide area to be covered, thus reducing work efficiency.

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an adjustable-width adhesive scraper, including a scraper plate 1. A protective box 3 is fixedly connected to the rear side of the scraper plate 1. A rotating rod 4 is rotatably connected to the rear side of the protective box 3. A bevel gear 5 is fixedly connected to the front side of the rotating rod 4. Rotating the rotating rod 4 drives the bevel gear 5 to rotate. Threaded rods 6 are rotatably connected to the left and right ends inside the protective box 3. A bevel gear 7 is fixedly connected to one end of the threaded rod 6. The bevel gear 5 and the bevel gear 7 are meshed. Rotating the bevel gear 5 will drive the bevel gear 7 to rotate. The threaded rod 6 is rotated, and a threaded block 8 is fixedly connected to the outside of the threaded rod 6. An extension plate 9 is fixedly connected to the outside of the threaded block 8. The other end of the threaded rod 6 is rotatably connected to a limit block 10, which serves as a limit. A telescopic mechanism 2 is fixedly connected to the top of the scraper 1. The telescopic mechanism 2 is used to extend the length. A warning sign 11 is provided on the rear right end of the scraper 1. A screw 12 is threadedly connected to the outside of the warning sign 11. The warning sign 11 is fixed by the screw 12. Multiple grooves 13 are equidistantly opened on the front side of the scraper 1 to drain excess adhesive.

[0032] Specifically, rotating the rotating rod 4 causes the bevel gear 5 to rotate. Due to the meshing of bevel gear 5 and bevel gear 7, bevel gear 7 is driven to rotate. This rotation causes the threaded rod 6 to rotate as well. Since the threaded block 8 is threaded with the threaded rod 6, the rotation of the threaded rod 6 will cause the threaded block 8 to move along the axial direction of the threaded rod 6. Consequently, the extension plate 9 connected to the threaded block 8 will also move accordingly. The limiting block 10 restricts the range of movement of the threaded block 8 to ensure that it will not disengage from the threaded rod 6. In this way, the extension plate 9 is moved, thereby allowing the scraper plate 1 to expand. A warning sign 11 is specially provided on the rear right end of the scraper plate 1. The warning sign 11 is connected to the screw 12 by the outer thread to fix it. In addition, multiple grooves 13 are provided at equal intervals on the front side of the scraper plate 1 to facilitate the effective drainage of excess adhesive.

[0033] Reference Figure 1 , Figure 2 and Figure 5The telescopic mechanism 2 includes a fixed block 201 fixedly connected to the top, the fixed block 201 fixedly connected to the top of the scraper plate 1, and L-shaped plates 202 fixedly connected to the left and right sides of the fixed block 201. The bottom of the L-shaped plates 202 is threadedly connected to a screw 203. Multiple engaging grooves 204 are equidistantly opened on the outer side of the L-shaped plates 202. A slot rod 205 is slidably connected to the inner side of the engaging groove 204. The slot rod 205 can cooperate with the engaging groove 204 to play the role of engaging. A handle 206 is fixedly connected to the adjacent side of the two L-shaped plates 202. A connecting rod 17 is fixedly connected to the top of the handle 206. A ring 18 is provided on the outer side of the connecting rod 17 for better carrying.

[0034] Specifically, the L-shaped plate 202 is securely fixed in the required position by screw 203. When a snap-fit ​​operation is required, the snap-fit ​​rod 205 is slid into the appropriate snap-fit ​​groove 204 to achieve snap-fit ​​positioning between the components. The handle 206 has an extension function, which can be used to apply to different areas. The handle 206 is easy for the operator to hold and the position of the handle 206 can be flexibly adjusted according to actual needs for better operation. The top of the handle 206 is fixedly connected to the connecting rod 17. The outer side of the connecting rod 17 is provided with a ring 18 for easy carrying.

[0035] Reference Figure 1 and Figure 3 A rubber ring 14 is provided on the outside of the rotating rod 4. A screw 15 is threadedly connected to the outside of the rubber ring 14. The rubber ring 14 is fixed by the screw 15, which can better operate the rotating rod 4. Screws 16 are threadedly connected to the top left and right sides of the scraper plate 1 to fix it.

[0036] Specifically, a rubber ring 14 is provided on the outer side of the rotating rod 4. The outer side of the rubber ring 14 is connected to the screw 15 by threads. The rubber ring 14 is fixed by the screw 15 to achieve better operation of the rotating rod 4. The top left and right sides of the scraper plate 1 are connected to the screw 16 by threads to play a fixing role.

[0037] Working principle: By rotating the rotating rod 4, the bevel gear 5 rotates. Due to the meshing relationship between the bevel gear 5 and the bevel gear 7, the bevel gear 7 rotates, which in turn causes the threaded rod 6 to rotate. Since the threaded block 8 is threadedly engaged with the threaded rod 6, the rotation of the threaded rod 6 will drive the threaded block 8 to move along the threaded rod 6, thereby causing the extension plate 9 connected to the threaded block 8 to move. The limiting block 10 restricts the range of movement of the threaded block 8 to prevent it from disengaging from the threaded rod 6, thus enabling the extension plate 9 to move and the scraper plate 1 to expand.

[0038] The L-shaped plate 202 is stably fixed in the required position using screw 203. When a snap-fit ​​operation is required, the snap-fit ​​rod 205 is slid into the appropriate snap-fit ​​groove 204 to achieve snap-fit ​​positioning between components. This allows for extension and application to different areas. The handle 206 makes it convenient for the operator to hold, move, or operate the entire device. The position of the handle 206 can be flexibly adjusted according to actual needs for better operation.

[0039] 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 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
