Description

Technical Field

[0001] This utility model mainly relates to the field of scraping technology, specifically to a coating scraping device for building decoration. Background Technology

[0002] In interior decoration work, wall coating scraping is an important preparatory work. Before applying a new coating to the interior walls, it is necessary to completely remove the residual coating on the walls to avoid unevenness or cracking of the subsequent new coating.

[0003] Due to space constraints during interior decoration work, especially when using an extension rod to remove coatings from the ceiling, the limited space causes the blade to contact the wall at an angle close to 90°, making it impossible for the user to push the blade properly for coating scraping.

[0004] The inventor proposed a deflectable operating lever that can change the contact angle between the blade and the wall in a confined space. It also features a combination of vertical and horizontal handles, making it convenient for users to push the horizontal handle to scrape the wall coating with the blade. Utility Model Content

[0005] 1. Technical problem solved by the utility model:

[0006] This utility model provides a coating scraper device for building decoration, which solves the technical problem that existing scrapers cannot properly scrape coatings in confined spaces due to the excessive contact angle between the blade and the wall.

The top rear side of the operating rod 1 is movably connected to the bottom rear side of the auxiliary rod 2. A rotating cylinder 3 is movably connected to the top of the operating rod 1. A blade holder 7 is threadedly connected to the top of the auxiliary rod 2. Fixing bolts 71 are threadedly connected to the left and right sides of the top of the blade holder 7. A blade 72 is detachably snapped into the middle of the blade holder 7. The left and right ends of the blade 72 are respectively sleeved with the middle of the two fixing bolts 71.

[0035] In this embodiment, a vertical grip 11 is fixedly sleeved at the bottom of the operating lever 1, a positioning seat 12 is movably connected to the front top of the operating lever 1, and an adjusting screw 13 is movably connected to the middle of the positioning seat 12.

[0036] The vertical grip 11 works in conjunction with the control lever 1 for easy gripping and use by the user.

[0037] In this embodiment, an auxiliary seat 21 is movably connected to the bottom front side of the auxiliary rod 2. The middle part of the auxiliary seat 21 is threadedly connected to the top of the adjusting screw 13. The deflection angle of the auxiliary rod 2 at the top of the operating rod 1 is 0°-50°.

The user holds the handle 51 and turns the limiting screw 5 to complete the locking and release of the limiting screw 5 and the deflection seat 4 outside the rotating drum 3. The user can hold the limiting screw 5 to fix the rotating drum 3, and hold the vertical handle 11 with the other hand to rotate the operating rod 1 to change the working position of the blade 72 to perform coating scraping operation.

[0041] In this embodiment, a throttle 51 is fixedly provided in the middle of the limiting screw 5, a horizontal grip 6 is movably sleeved on the left end of the limiting screw 5, and the right end of the limiting screw 5 is engaged with the limiting hole 31.

[0042] The horizontal handle 6 is designed so that users can hold the horizontal handle 6 with one hand and use it as a base to hold the vertical handle 11 with the other hand to complete the rotation of the operating lever 1 on the rotating drum 3 and the deflection of the limiting screw 5 on the horizontal handle 6. At the same time, the design of the horizontal handle 6 makes it easy for users to push the blade 72 to scrape the wall coating.

[0043] In this embodiment, the bottom of the tool holder 7 is threadedly connected to an extension rod 73, and the bottom of the extension rod 73 is threadedly connected to the top of the auxiliary rod 2.

[0044] The extension bar 73 can be added or removed as needed to accommodate the wall height and area to facilitate wall coating scraping operations.
