Description

Technical Field

[0001] This utility model relates to a portable tool for plastering inside and outside corners. Background Technology

[0002] In modern building interior decoration practices, plastering is generally used for the initial finishing of wall and column surfaces. It plays a crucial role in reducing structural surface damage from impacts, filling in unevenness, correcting deviations in wall verticality and horizontality, and providing a smooth base for subsequent finishing layers. These functions place high demands on the quality of plastering at wall corners. Therefore, the construction of corners is a key focus of quality inspection during plastering.

[0003] In current wall plastering construction, the initial plastering of inside and outside corners is typically done using a traditional wooden-handled plastering board. Then, a corner scraper is used to smooth and finish the corners, ensuring they are straight and regular. This method, limited by the plastering tools, is only suitable for 90° corners and produces poor results for non-perpendicular corners. In daily construction, the numerous steps and inconvenient operation significantly impact on-site plastering efficiency. Consequently, some workers omit the corner scraper step for convenience, further complicating the quality control of inside and outside corners during plastering.

[0004] Therefore, a portable tool for plastering inside and outside corners is proposed to address the above problems. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-3 A portable tool for plastering inside and outside corners includes a left trowel 1, a right trowel 2, a hand handle 3, a sliding sleeve 4, a snap-fit ​​component, and a diagonal brace component; the left trowel 1 and the right trowel 2 are rotatably connected to the front end of the hand handle 3, the sliding sleeve 4 is slidably connected to the hand handle 3, the sliding sleeve 4 is provided with a snap-fit ​​component inside, and the sliding sleeve 4 is connected to the left trowel 1 and the right trowel 2 respectively through the diagonal brace component.

[0024] Specifically, the opposite surfaces of the left trowel 1 and the right trowel 2 are each connected to a rotating seat 5, and the front end of the hand handle 3 is connected to a rotating shaft 6. The two rotating seats 5 are interlocked and rotatably connected to the rotating shaft 6.

[0025] Specifically, a deep groove 7 is formed on the outer wall of the handheld lever 3, and multiple slots 8 are formed at the bottom of the deep groove 7; the locking assembly is locked in the slots 8. The locking assembly includes a locking member 9, a transmission plate 10, a button 11, and a spring 12; a chamber 13 is formed inside the sliding sleeve 4, and a support platform 14 is set at the bottom of the chamber 13. The transmission plate 10 is located on the support platform 14. The front end of the transmission plate 10 is rotatably connected to the locking member 9, the upper end of the rear end is connected to the button 11, and the lower end of the rear end is connected to the spring 12. The upper end of the button 11 protrudes from the outer wall of the sliding sleeve 4; the lower end of the locking member 9 is locked in the slot 8. A through groove communicating with the slot 8 is formed at the front end of the chamber 13, and the locking member 9 passes through the through groove and is locked in the slot 8.

[0026] Specifically, the diagonal brace assembly includes two fixed plates 15, two diagonal braces 16, and two fixed seats 17. The back of the left trowel plate 1 and the right trowel plate 2 are each connected to a fixed seat 17, and the two sides of the sliding sleeve 4 are each connected to a fixed plate 15. One end of the diagonal brace 16 is rotatably connected to the fixed plate 15, and the other end is rotatably connected to the fixed seat 17.

[0027] Specifically, the handle 18 is connected to the rear end of the handheld lever 3.

[0028] Specifically, the left trowel 1 and right trowel 2 are adjusted to a suitable angle so that the locking piece 9 engages with the slot 8 on the handle 3. The end of the handle 3 is connected to the left trowel 1 and right trowel 2 respectively via a rotating shaft 6, ensuring that the left trowel 1 and right trowel 2 remain stable after the locking piece 9 engages with the slot 8. The rotating shaft 6 is inserted into two rotating seats 5 and then welded to the handle 3, allowing the left trowel 1 and right trowel 2 to open and close according to the position of the sliding sleeve 4. After use or when adjusting different angles, pressing the button 11 utilizes the elasticity of the spring 12 to disengage the locking piece 9 from the slot 8, completing the adjustment of the left trowel 1 and right trowel 2 to different angles.

[0029] When using the trowel, pull the sliding sleeve 4 to adjust the trowel to the desired angle; adjust the height of the trowel to ensure that the large surface of the trowel is in close contact with the plastering patch at the inside and outside corners of the wall; use the handle 3 to push and pull the trowel to complete the plastering of the inside and outside corners of the wall; after completing the plastering of the inside and outside corners of the wall, press button 11 to retract the sliding sleeve 4. By ensuring that the trowel is in close contact with the plastering patch, the thickness of the plastering at the inside and outside corners of the wall is guaranteed, thus improving the efficiency of plastering at the inside and outside corners.

[0030] Specifically, by combining the hand handle 18, the sliding sleeve 4, and the trowel board, the angle of the trowel board is controlled by the sliding sleeve 4 during wall corner plastering. The angle deviation is prevented by the locking groove 8 on the sliding sleeve 4. The sliding sleeve 4 is equipped with a locking piece 9 and a spring 12 for easy adjustment of the trowel board angle, allowing for multi-angle adjustment to meet on-site construction needs. When not in use, the sliding sleeve 4 is pulled to the end of the hand handle 3, taking up little space and facilitating storage. When plastering wall corners, pulling the sliding sleeve 4 causes the locking piece 9 inside to engage with the corresponding angle fixing groove 8, thus fixing and using the trowel board angle.

[0031] This portable tool for plastering inside and outside corners effectively avoids the drawbacks of traditional construction methods, such as numerous steps and difficulty in quality control, ensuring improved quality and efficiency in corner plastering. During plastering, the device adheres to the plaster patch, guaranteeing the thickness of the plaster at the corners and preventing issues like non-perpendicular corners or insufficient plaster thickness caused by worker skill in traditional methods. This improves the appearance and quality of the corner plastering. Compared to traditional methods, this device is more time-saving and labor-saving, significantly increasing the efficiency of corner plastering. This improved quality and efficiency in corner plastering has earned the company recognition from homeowners and the community.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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.
