Description

Technical Field

[0001] The utility model relates to the technical field of wall construction, in particular to a novel multifunctional wall decoration tool. Background Art

[0002] With the improvement of economic level and quality of life, people's aesthetic requirements for rooms have further improved. The quality of wall plastering and whitewashing has a great impact on the overall aesthetics of the house, especially the quality of plastering and whitewashing at the corners of the yin and yang walls is very obvious and easy to observe, and has the most obvious impact on the aesthetics of the house.

[0003] When plastering and whitewashing the Yin-Yang corners, it is necessary to ensure that the corner edge line is perpendicular or horizontal to the main body of the house, and the corner must also be kept straight and square. For example, the existing document CN202222485194.1 discloses a scraper device for exterior wall paint, including a scraper body and a mounting plate, one end of the scraper body is slidably embedded and installed inside one end of the mounting plate, and a storage groove is provided on the outer surface of the other end of the mounting plate, and an extension plate is slidably connected to the inside of the storage groove, and a connecting plate is fixedly connected to one end of the extension plate; although the length of the scraper device can be changed, and the angle of the handle can be changed by the provided positioning and clamping mechanism, the quality of plastering and whitewashing the Yin-Yang corners still cannot be improved when facing the Yin-Yang corners. Most engineering teams use simple right-angle tools to straighten the Yin-Yang corners and use a right-angle ruler to measure and correct them later, but the later corrections have a great influence on work efficiency. Utility Model Content

[0004] The utility model aims to solve the above problems, thereby providing a novel multifunctional wall decoration tool which can be used for construction on yin and yang corners.

[0005] The utility model solves the above problems and adopts the following technical solutions:

[0006] A novel multifunctional wall decoration tool comprises a main scraper, a threaded sleeve is arranged on one surface of the main scraper, a telescopic rod is screwed in the threaded sleeve, a handle is arranged at the end of the telescopic rod, and an auxiliary scraper is also included. The auxiliary scraper is perpendicular to the main scraper and is movably connected to the side wall of the main scraper. A limiting mechanism is arranged between the main scraper and the auxiliary scraper.

[0007] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0008] The internal and external corners are constructed by means of a vertical and movably connected auxiliary scraper and main scraper. When switching between coating the internal and external corners, the auxiliary scraper is rotated 180 degrees and its position is limited by a limiting mechanism to keep the construction straight and square. The controllable length range is adjusted by the telescopic rod.

[0009] As a preferred embodiment, a further technical solution of the utility model is:

[0010] An elliptical movable groove is opened on the side wall of the main scraper, and a limit tube is fixed in the middle of the inner cavity of the movable groove. A protrusion is vertically arranged on the auxiliary scraper. The protrusion is slidably connected with the movable groove and has a cavity structure. A sliding rod is arranged in the cavity of the protrusion. The sliding rod movably passes through the limit tube and a limit ball is arranged at the end.

[0011] The diameter of the limiting ball is larger than the diameter of the limiting tube.

[0012] The limiting ball is threadedly connected to the end of the sliding rod.

[0013] The limiting mechanism includes a locking knob, which is located on the same side as the handle and has a thread that penetrates the main scraper into a movable groove. Notches are symmetrically opened on the cavity wall of the protrusion. The locking knob is movably located in the notch and a clamping plate is fixed on the inner end.

[0014] The grip comprises a handle, one end of which is provided with a positioning sleeve, which is rotatably sleeved on the end of the telescopic rod, a positioning screw hole is provided on the positioning sleeve, a positioning knob is screwed in the positioning screw hole, and the inner end of the positioning knob abuts against the telescopic rod.

[0021] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0022] See also Figure 1-Figure 5A new type of multifunctional wall decoration tool includes a main scraper 1, a threaded sleeve is arranged on one surface of the main scraper 1, a telescopic rod 3 is screwed in the threaded sleeve, a handle 4 is arranged at the end of the telescopic rod 3, and an auxiliary scraper 2 is also included. The auxiliary scraper 2 is perpendicular to the main scraper 1, and the auxiliary scraper 2 is movably connected to the side wall of the main scraper 1. A limiting mechanism is arranged between the main scraper 1 and the auxiliary scraper 2. The auxiliary scraper 2 is adjusted 180 degrees to ensure the switching between the positive and negative angles, and the construction angle of the auxiliary scraper 2 and the main scraper 1 at the negative angle can also meet the main scraper for plane construction.

[0023] An elliptical movable groove 11 is provided on the side wall of the main scraper 1, and a limiting tube 12 is fixed in the middle of the inner cavity of the movable groove 11. A protrusion 21 is vertically arranged on the auxiliary scraper 2, and the protrusion 21 is inserted in the movable groove 11. The protrusion 21 is slidably connected with the movable groove 11 and is a cavity structure. A sliding rod 22 is arranged in the cavity of the protrusion 21, and the sliding rod 22 movably passes through the limiting tube 12 and a limiting ball 23 is arranged at the end. When the angle of the auxiliary scraper 2 needs to be adjusted, the protrusion 21 is pulled out of the movable groove, the auxiliary scraper 2 is rotated 180 degrees, and then the protrusion 21 is inserted into the movable groove.

[0024] The diameter of the limiting ball 23 is greater than the diameter of the limiting tube 12 . The limiting ball 23 limits the position of the sliding rod 22 to prevent the sliding rod 22 from escaping from the limiting tube 12 .

[0025] The limiting ball 23 is threadedly connected to the end of the sliding rod 22 .

[0026] The limiting mechanism includes a locking knob 5, which is located on the same side as the handle 4 and has a thread that penetrates the main scraper 1 into the movable groove 11. Notches 24 are symmetrically provided on the cavity wall of the protrusion 21. The locking knob 5 is movably located in the notch 24 and a clamping plate is fixed at the inner end. When the auxiliary scraper 2 is properly positioned, the locking knob 5 is rotated so that the clamping plate presses and fixes the protrusion 21. When the position of the auxiliary scraper 2 needs to be adjusted, the clamping plate is loosened and the protrusion 21 moves outward and disengages from the locking knob 5.

[0027] The grip 4 includes a handle 41, one end of which is provided with a positioning sleeve 42. The positioning sleeve 42 is rotatably mounted on the end of the telescopic rod 3. A positioning screw hole is provided on the positioning sleeve 42, and a positioning knob is screwed into the positioning screw hole. The inner end of the positioning knob abuts against the telescopic rod 3. When facing construction at different positions, the positioning sleeve 42 is rotated and locked by the positioning knob.

[0028] The internal and external corners are constructed by means of a vertical and movably connected auxiliary scraper and main scraper. When switching between coating the internal and external corners, the auxiliary scraper is rotated 180 degrees and its position is limited by a limiting mechanism to keep the construction straight and square. The controllable length range is adjusted by the telescopic rod.
