On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0028] like Figure 1-3 As shown, a rib-free scraper bar comprises:

[0029] A vertical support mechanism, on which a scraper plate 2 is slidably connected, and the vertical support mechanism comprises at least one vertical beam 1;

[0030] At least one telescopic nail 3, which is arranged on the vertical support mechanism and is used to adjust the gap between the scraping plate 2 and the wall surface;

[0031] The lifting mechanism 4 is arranged at the lower end of the vertical supporting mechanism and can support the lifting and lowering adjustment of the vertical supporting mechanism.

[0032] Specifically, the scraper plate 2 is guided by the vertical support mechanism to slide vertically in the vertical plane for leveling. The telescopic nails 3 can adjust the position and angle of the vertical beam 1 according to the condition of the wall surface, thereby adjusting the flatness and verticality of the wall surface, and then changing the gap between the scraper plate 2 and the wall surface. The lifting mechanism 4 is convenient for adjusting the height of each vertical beam 1, so that each vertical beam 1 can touch the roof, increase stability and adapt to the unevenness of the ground.

[0033] Furthermore, the telescopic nail 3 can be adjusted accurately and can achieve fine-tuning, thereby ensuring the flatness and verticality accuracy of the wall surface. The vertical beam 1 and the scraper plate 2 can be set to an L-shape, a cross-shape, an H-shape, etc.

[0034] In this embodiment, two vertical beams 1 are provided, and the two vertical beams 1 and the scraper plate 2 form an H-shaped structure. A lifting mechanism 4 is provided at the lower end of each vertical beam 1.

[0035] Specifically, the H-shaped structure ensures the stability of the vertical beam 1 guiding the scraping plate, thereby ensuring the scraping effect. The scraping plate 2 is set to a plurality of different lengths, which are selected according to the interval between the two vertical beams 1.

[0036] In this embodiment, the vertical beam 1 includes a first beam 1.1 and at least one second beam 1.2, and the first beam 1.1 and the second beam 1.2 are coaxially connected end to end and are detachable.

[0037] Specifically, the length of the vertical beam 1 is increased by connecting at least one second beam 1.2 through the first beam 1.1, so as to adapt to walls of different heights. The first beam 1.1 and the second beam 1.2 can be detachably connected to facilitate storage, transportation and use in different construction environments.

[0038] In this embodiment, a connecting plate 5 and connecting screws are also included. First opening grooves are provided at both ends of the first beam 1.1, and second opening grooves are provided at both ends of the second beam 1.2. Threaded holes matching the connecting screws are provided in the first opening groove and the second opening groove, respectively. An avoidance hole is provided on the connecting plate 5. The first opening groove and the second opening groove are spliced ​​into a rectangular groove. The connecting plate 5 is arranged in the groove, and the connecting screws pass through the avoidance hole and are connected to the threaded hole.

[0039] Specifically, the first beam 1.1 and the second beam 1.2 are fixed by the connection plate 5 and the connection screws.

[0040] Furthermore, the first opening groove is arranged on the side of the first beam 1.1 slide groove away from the scraper plate 2, and a limit plate is arranged on the side of the first opening groove away from the scraper plate 2, and the limit plate is used to limit the connection plate 5 from escaping along the depth direction of the first opening groove (the length direction of the first opening groove is the lifting and lowering movement direction of the scraper plate 2).

[0041] Furthermore, the first beam 1.1 and the second beam 1.2 have the same horizontal cross-section and only differ in length.

[0042] In this embodiment, sliders are provided at both ends of the scraping plate 2, and sliding grooves matching with the sliders are provided at adjacent ends of the two vertical beams 1, and the horizontal cross-section of the sliding groove is T-shaped, with open structures at both ends.

[0043] Specifically, the sliding of the scraper plate 2 on the vertical beam 1 is achieved by the sliding cooperation connection between the slider and the slide groove, and the T-shaped groove body also ensures horizontal stability to avoid horizontal movement. The open structure at both ends facilitates the disassembly of the scraper plate and the vertical beam 1.

[0044] Furthermore, limiting grooves are provided on the sides of the two slide grooves that are away from each other, and a limiting block that cooperates with the limiting grooves is provided on the sliding block to prevent the scraping plate 2 from tilting.

[0045] In this embodiment, the sliding block and the scraping plate form a mountain-shaped structure, and the opening of the sliding groove faces away from the wall.

[0046] Specifically, the scraping plate is disassembled on the side away from the wall to prevent excess wall material from being scraped off and entering the chute, and the middle part of the mountain-shaped structure is flush with or protrudes from the back side of the vertical beam 1.

[0047] In this embodiment, the vertical beam 1 is an aluminum alloy frame with an anodized film layer on the surface.

A screwing portion is provided at one end of the threaded section away from the tapered section, and the other end of the threaded section passes through the vertical beam and contacts the wall surface through the tapered section.

[0052] Specifically, the distance between the vertical beam 1 and the wall is changed by driving the telescopic nail 3 through the screwing part, so as to adapt to the unevenness of the wall and support the vertical beam 1 to be vertical.

[0053] In this embodiment, the lifting mechanism 4 is a scissor frame, and the scissor frame can be detachably connected to the vertical beam 1.

[0054] Specifically, the vertical beam 1 is lifted and lowered by the scissor frame so that the upper end of the vertical beam 1 can touch the roof, and the vertical beam 1 is subjected to forces up and down to ensure stability.

[0055] In this embodiment, a rib-free scraper is used on a wall in a house as an example:

[0056] 1. Choose vertical beams of different lengths according to the height of the house 1;

[0057] A scissor frame and a plurality of second beams 1.2 are connected at both ends of the first beam 1.1, so that the scissor frame can support the vertical beam 1 to touch the roof;

[0058] 2. Select a scraper plate of appropriate length according to the length of the wall, and adjust the interval between the two vertical beams 1;

[0059] After connecting the scraper plate 2 to form an H-shaped structure, adjust each telescopic nail 3 to ensure that the scraper plate 2 can scrape the wall flat before the vertical beam 1 touches the top;

[0060] 3. Lift and lower the scraper plate 2, and use the scraper plate 2 to timely check and level the wall paint coating.

[0061] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
