Description

Technical Field

[0001] This utility model relates to the field of building decoration and renovation tools, specifically a high-efficiency uniform scraper for interior decoration and renovation. Background Technology

[0002] In interior decoration and renovation, a scraper is a tool used to scrape and apply materials such as putty and paint to achieve a smooth finish on walls and floors.

[0003] Traditional scrapers typically have a fixed flat panel. When working on non-planar surfaces such as curved walls and cylinders, the flat scraper struggles to conform to the curved surface, resulting in uneven application, inconsistent thickness, and inadequate edge finishing. To achieve uniform application on non-planar surfaces, a specialized curved scraper is required. However, different non-planar surfaces have different curvature angles, necessitating frequent tool changes to adapt to different surfaces, leading to low application efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency and uniform scraper for interior decoration and renovation. The scraper's curvature can be flexibly adjusted according to different construction needs to meet the coating requirements of different non-planar structures, thereby achieving efficient and uniform coating operations and improving construction quality and efficiency.

[0005] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: a high-efficiency uniform scraper for interior decoration and renovation, including a holding rod; Multiple connecting rods, wherein the multiple connecting rods are disposed on the grip rod; A flexible panel, said panel being hinged to the plurality of said connecting rods; Multiple adjustment devices are provided, which are located between the grip rod and the connecting rod, and the multiple adjustment devices can adjust the curvature of the panel.

[0006] In some embodiments, the adjusting device includes a toothed bar that passes through the gripping rod and is fixedly connected to the connecting rod; A gear, rotatably disposed within the gripping rod, meshing with the rack teeth; A switching element is provided on the grip rod and can switch between the rotating state and the fixed state of the gear.

[0007] In some embodiments, the switching element includes a ratchet, which is rotatably disposed within the grip lever and coaxially fixed with the gear; A pawl, which is rotatably disposed within the gripping rod and engages with the ratchet; An adjusting rod is provided on the gripping rod, and a rotatable pawl is provided at the bottom of the adjusting rod. A torsion spring is provided between the pawl and the adjusting rod.

[0008] In some embodiments, the adjusting rod is a T-shaped rod.

[0009] In some embodiments, the grip lever includes a grip portion; Two adjustment parts are symmetrically arranged at both ends of the gripping part; A sliding groove extends through the grip and the adjustment parts, and the sliding groove is provided with slidable teeth; An adjustment groove is provided, which is connected to the sliding groove, and the gear and the switching component are provided in the adjustment groove.

[0010] In some embodiments, the grip portion is provided with anti-slip texture.

[0011] In some embodiments, the connecting rod is provided with a rotating groove at one end near the panel, and the panel is provided with a connecting seat at one end near the connecting rod, the connecting seat being axially connected to the rotating groove.

[0012] In summary, this utility model has the following beneficial effects: This invention allows for quick and convenient adjustment of the connecting rod's position on the gripping rod via an adjustment device, thereby adjusting the panel's curvature to conform to the shape of the surface to be treated. Unlike traditional scrapers, it eliminates the need for frequent tool changes or complex manual adjustments, thus shortening preparation time and improving efficiency. Furthermore, because the panel can be bent to fit the surface, the scraper adheres closely during application, ensuring even distribution of material and preventing material accumulation or uneven application due to misalignment.

[0013] This invention uses a ratchet and pawl mechanism to ensure that the gears can only rotate in one direction, preventing the panel from rebounding due to external force during the scraping and adjustment process, thus ensuring the coating quality. At the same time, it can be operated by a single person without the aid of tools, improving the convenience of adjustment and ensuring that the curvature adjustment of the panel can accurately match the curvature of the construction surface, further improving the coating effect.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] refer to Figure 1-3 This high-efficiency, uniform scraper for interior decoration includes a gripping rod 1, multiple connecting rods 2, a flexible panel 3, and multiple adjusting devices 4. The gripping rod 1 serves as the operating handle for the entire scraper, facilitating application to the wall surface. Multiple connecting rods 2 are mounted on the gripping rod 1; the specific number of connecting rods 2 can be determined based on the length and bending requirements of the panel 3. By rationally setting the number and spacing of the connecting rods 2, the panel 3 can be subjected to uniform force during bending, achieving a smooth curvature change. The panel 3 is hinged to the multiple connecting rods 2. The panel 3 can be made of flexible materials such as high-strength metal sheets, allowing it to bend with the movement of the connecting rods 2. The adjusting devices 4 are located between the gripping rod 1 and the connecting rods 2, and can adjust the curvature of the panel 3 to adapt to different non-planar structures during application.

[0018] In some embodiments, the adjusting device 4 includes a rack 41, a gear 42, and a switching element. The rack 41 passes through the gripping rod 1 and is fixedly connected to the connecting rod 2. The gear 42 is rotatably disposed inside the gripping rod 1 and meshes with the rack 41. Both the rack 41 and the gear 42 can be made of high-strength alloy steel to ensure that they do not deform or wear during long-term use. The switching element is disposed on the gripping rod 1 and can realize the switching between the rotating state and the fixed state of the gear 42.

[0019] In some embodiments, to enable single-person operation, avoid springback during panel 3 adjustment, ensure that the curvature adjustment of panel 3 can accurately match the curvature of the construction surface, and further improve the coating effect, the panel 3 switching component includes a ratchet 43, a pawl 44, and an adjusting rod 45. The ratchet 43 is rotatably disposed in the grip rod 1 and coaxially fixed with the gear 42, and can rotate synchronously with the gear 42. The pawl 44 is rotatably disposed in the grip rod 1 and engages with the ratchet 43. The adjusting rod 45 is disposed on the grip rod 1, and the bottom of the adjusting rod 45 is provided with a rotatable pawl 44. A torsion spring is provided between the pawl 44 and the adjusting rod 45, which can provide elastic force to keep the pawl 44 always in contact with the ratchet 43, thereby achieving one-way locking of the gear 42 and avoiding springback during panel 3 adjustment.

[0020] In some embodiments, the adjusting rod 45 is a T-shaped rod, which allows the construction personnel to rotate the adjusting rod 45 to rotate the pawl 44, release the lock on the ratchet 43, and thus realize the reverse rotation of the gear 42.

[0021] In some embodiments, the grip rod 1 includes a grip portion 11, two adjustment portions 12, a sliding groove 13, and an adjustment groove 14. The grip portion 11 is the part held and operated by the construction worker, and may be provided with anti-slip textures. It is ergonomically designed to conform to the gripping habits of the human hand. The anti-slip textures can increase the roughness of the contact surface to improve friction and prevent the scraper from slipping due to sweaty hands or material contamination during construction. The shape of the anti-slip textures can be wavy, serrated, or grid-like, etc., and their size and spacing are optimized to provide sufficient friction without affecting grip comfort. Two adjustment parts 12 are symmetrically arranged at both ends of the grip part 11 for mounting and supporting the adjustment device 4. A sliding groove 13 is provided through the grip part 11. Two sliding grooves 13 are provided through the grip part 11. One sliding groove 13 is provided through the adjustment part 12. A sliding tooth 41 is provided in the sliding groove 13. The sliding groove 13 can guide the linear movement of the tooth 41. The adjustment groove 14 is connected to the sliding groove 13. The adjustment groove 14 can accommodate the gear 42, ratchet 43 and pawl 44 to realize the free rotation of the gear 42, ratchet 43 and pawl 44.

[0022] In some embodiments, the connecting rod 2 is provided with a rotating groove 21 at one end near the panel 3 to provide installation space for the shaft connection structure. The panel 3 is provided with a connecting seat 31 at one end near the connecting rod 2. The connecting seat 31 is shaft-connected to the rotating groove 21 and can be fixed by a shaft pin. The connecting seat 31 can rotate around the shaft pin, thereby realizing the bending deformation of the panel 3.

[0023] The construction worker can drive the rack 41 to slide by rotating the gear 42, thereby moving the connecting rod 2 and bending the panel 3. When the panel 3 is bent to the required curvature, the adjusting rod 45 is released, and under the action of the torsion spring, the pawl 44 re-engages with the ratchet 43, locking the gear 42 in the current position, thereby fixing the curvature of the panel 3.

[0024] The specific working principle is as follows: When the curvature of panel 3 needs to be adjusted to make it concave, the operator places panel 3 against the surface to be worked on and rotates the adjusting rod 45 on the grip 11. The pawl 44 rotates with the adjusting rod 45, disengaging from the ratchet 43, at which point the gear 42 is in a free-rotating state. The operator then presses panel 3 against the surface to be worked on, applying a concave force to the center of the panel. Since the connecting rod 2 and panel 3 are connected by a hinge, the bending deformation of panel 3 causes the connecting rod 2 to move. Under this force, the connecting rod 2 on the grip 11 moves towards the grip rod 1, thereby driving the rack 41 to slide within the sliding groove 13. When panel 3 is bent to the desired curvature, the operator releases the adjusting rod 45. Under the action of the torsion spring, the pawl 44 re-engages with the ratchet 43, locking the gear 42 in its current position, thus fixing the curvature of panel 3.

[0025] When it is necessary to adjust the curvature of panel 3 to make it convex, the worker places panel 3 against the surface to be worked on and pushes the teeth 41 on the grip 11, causing the connecting rod 2 to move towards panel 3. Since the connecting rod 2 and panel 3 are connected by a hinge, the movement of the connecting rod 2 will cause panel 3 to bend and deform, thus obtaining a curvature that matches the surface to be worked on. Because the pawl 44 and ratchet 43 engage, the gear 42 is locked in one direction. At this time, the connecting rod 2 can only move towards panel 3 and will not be rebounded by the internal spring force of panel 3, thus fixing the curvature of panel 3.

[0026] After adjustment, apply materials such as putty or paint to the construction surface, ensuring panel 3 adheres tightly to the surface. The worker then pushes the gripping rod 1 to slide panel 3 across the surface, evenly spreading and smoothing the material to ensure uniform distribution. After completion, clean any remaining material from the scraper and straighten panel 3 for storage and future use.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
