[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a large-area smoothing device for exterior wall coating application.

[0028] like Figure 1-4As shown, this utility model discloses a large-area smoothing device for exterior wall coating construction, comprising a first scraper 1, a fixing block 7 welded to the top of the first scraper 1, a bushing 8 welded to the side of the fixing block 7, a shaft 5 sleeved inside the bushing 8, a second baffle 14 welded to one end of the shaft 5, the top of the second baffle 14 fitting against the bottom of the bushing 8, and a fixing frame 4 welded to the other end of the shaft 5. By installing the shaft 5 and the bushing 8, the shaft 5 and the bushing 8 provide a rotatable effect for the second scraper 2, allowing the second scraper 2 to rotate to the side of the first scraper 1, thus achieving an extension effect for both the first scraper 1 and the second scraper 2, which is very convenient to use. A first fixing seat 3 is welded to the other end of the fixing frame 4, and the second scraper 2 is welded to the other end of the first fixing seat 3. A locking block 9 is welded to the side of the second scraper 2, and a slot 10 is opened on the side of the first scraper 1. By installing the first scraper 1 and the second scraper 2, the extension effect of the first scraper 1 and the second scraper 2 can be used to expand the smoothing area of ​​the device, thereby improving the efficiency of coating, and saving time and effort during use.

[0029] The second scraper 2 has a groove 17 at its bottom and a magnet 16 at its bottom, which is embedded in the groove 17. The second scraper 2 is made of iron. A pad 15 is provided at the bottom of the second scraper 2. A second external threaded rod 18 is welded to the top of the pad 15 and passes through the second scraper 2. A nut 19 is fitted onto the surface of the second external threaded rod 18, with one end of the nut 19 attached to the top of the second scraper 2. By installing the pad 15, when the pad 15 at the bottom of the second scraper 2 is worn during use, the nut 19 can be removed first, and then the pad 15 can be replaced. In this case, it is not necessary to replace the entire device, thus reducing the cost during use.

[0030] A groove 11 is formed at the top of the first scraper 1, and a first external threaded rod 12 is welded to the top of the locking block 9. The first external threaded rod 12 is located inside the groove 11, and a pressing turntable 13 is sleeved on the surface of the first external threaded rod 12. One end of the pressing turntable 13 is attached to the top of the first scraper 1. By installing the first external threaded rod 12, when the second scraper 2 moves to the appropriate position, the first external threaded rod 12 will be located inside the groove 11. Then, the pressing turntable 13 is rotated. The pressing turntable 13 can increase the friction between the locking block 9 and the locking groove 10, thereby providing a position fixing effect for the second scraper 2 and ensuring the stability of the second scraper 2 during use.

[0031] The top of the first scraper 1 is fixedly connected to the second fixing seat 23. The other end of the second fixing seat 23 is welded to the handle 24. The surface of the handle 24 is welded to the retaining ring 20. The surface of the handle 24 is fitted with an anti-slip sleeve 21. Both ends of the anti-slip sleeve 21 are attached to the retaining ring 20. By installing the anti-slip sleeve 21, the friction between the palm and the handle 24 can be increased, thereby making the device more stable to hold during use and more stable during use.

[0032] The other end of the first external threaded rod 12 is welded with a first baffle 6. The bottom of the first baffle 6 is attached to the extrusion turntable 13. By installing the first baffle 6, the extrusion turntable 13 can be limited, so that the extrusion turntable 13 will not detach from the first external threaded rod 12, which is very convenient to use.

[0033] Anti-slip balls 22 are bonded to the surface of the anti-slip sleeve 21. The anti-slip balls 22 are arranged in a ring shape. By installing the anti-slip balls 22, the friction of the surface of the anti-slip sleeve 21 can be further improved, which can improve the stability of the device when it is held.

[0034] The working principle of this large-area smoothing device for exterior wall coating construction is as follows: When using this device, the pad 15 should first be installed on the second scraper 2. When installing the pad 15, the magnet 16 can be embedded in the groove 17. Assuming the material of the second scraper 2 is iron, the magnetic attraction effect can be used to provide initial fixation for the pad 15. At this time, the second external thread rod 18 passes through the second scraper 2. Then, the nut 19 is sleeved on the surface of the second external thread rod 18 until one end of the nut 19 is attached to the top of the second scraper 2. Then the device can be used. When using this device, a fixing block 7 is welded to the top of the first scraper 1, and a bushing 8 is welded to the side of the fixing block 7. At the same time, a shaft 5 is sleeved inside the bushing 8, and a second baffle 14 is welded to one end of the shaft 5. At this time, the top of the second baffle 14 is attached to the bottom of the bushing 8, and a fixing frame 4 is welded to the other end of the shaft 5. At the same time, a first fixing seat 3 is welded to the other end of the fixing frame 4. At this time, the second scraper 2 is welded to the other end of the first fixing seat 3. The welding block 9 provides a slot 10 on the side of the first scraper 1. When painting a large area of ​​wall surface, the shaft 5 and bushing 8 can be used to rotate the second scraper 2 until the welding block 9 of the second scraper 2 is embedded in the slot 10 of the first scraper 1, making the first scraper 1 and the second scraper 2 in a straight line. At this time, the device can be extended, thereby expanding the smoothing area and improving the efficiency of painting. It is very time-saving and labor-saving when using it. When the device wears down after a period of use, the pad 15 is provided at the bottom of the second scraper 2. A second external threaded rod 18 is welded to the top of the pad 15. The second external threaded rod 18 passes through the second scraper 2, and a nut 19 is sleeved on the surface of the second external threaded rod 18. At this time, one end of the nut 19 is attached to the top of the second scraper 2, and the pad 15 can be replaced. When replacing it, the nut 19 can be removed first, and then the pad 15 can be replaced. At this time, it is not necessary to replace the entire device, reducing the cost of use.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
