Description

Technical Field

[0001] This utility model relates to the field of curved surface leveling technology, and in particular to a curved surface leveling device for building applications. Background Technology

[0002] In building construction, leveling refers to the process of smoothing uneven surfaces by masonry work, carpentry work, etc. When building houses and windows, the tops of houses and windows are often made into curved structures to enhance their aesthetics. When using putty or mortar to level the tops of houses and windows, leveling devices are needed. However, existing leveling devices can only level the curved surfaces of buildings, which has certain limitations. In order to meet market needs, a new type of curved surface leveling device for buildings is required.

[0003] A search revealed a Chinese patent with authorization number 202020083482.2, which discloses a leveling device for curved surfaces in construction, including a main body, a handle, the handle being fixed to the center of the bottom surface of the main body, and a blocking mechanism installed at the edge of the side wall of the main body. The aforementioned patented leveling device for curved surfaces in construction has the following shortcomings: Existing leveling devices typically lack positioning and fixing functions, preventing the adjustment of the device's metal sheet and scraper's curvature according to the different curvatures of the inner or outer curved surfaces. This results in instability when fixing the curvature of the metal sheet and scraper. Furthermore, the existing leveling devices offer insufficient anti-slip protection, reducing worker efficiency and failing to provide a reliable grip, thus decreasing operational stability. In addition, existing leveling devices cannot perform grinding operations, preventing the scraper from being replaced with a sanding plate for grinding curved surfaces, thus limiting the device's applicability and reducing its practicality.

[0029] Reference Figure 3 and Figure 7 Furthermore, the frame 1 also includes a fixing mechanism 4 for limiting and fixing the first adjusting rod group 104 and the second adjusting rod group 105. The fixing mechanism 4 consists of a fixing block 43 disposed on the surface of the frame 1, an anti-loosening screw sleeve 42 disposed on the surface of the fixing block 43, a fastening screw 41 disposed on the surface of the fixing block 43 and cooperating with the anti-loosening screw sleeve 42, a fastening pressure plate 44 disposed on the inner side of the fixing block 43, and an anti-slip pad 45 disposed on the inner wall of the fastening pressure plate 44. Fixing blocks 43 are installed on all surfaces of the frame 1, and the fixing blocks 43 are located on both sides of the first adjusting rod group 104 and the second adjusting rod group 105, respectively. An anti-loosening sleeve 42 is installed on one side of the fixed block 43. A fastening screw 41 is threadedly connected to the surface of the anti-loosening sleeve 42. One end of the fastening screw 41 passes through the anti-loosening sleeve 42 and the fixed block 43 and extends to the outside of the fixed block 43. The fastening screw 41 and the anti-loosening sleeve 42 cooperate with each other. A fastening pressure plate 44 is provided on the surface of one end of the fastening screw 41. The fastening pressure plate 44 and the surface of the fastening screw 41 rotate with each other. An anti-slip pad 45 is installed on the surface of the fastening pressure plate 44 away from the fastening screw 41. The surface of the anti-slip pad 45 contacts the surfaces of the first adjusting rod group 104 and the second adjusting rod group 105 respectively. By setting up a fixing mechanism, the curvature of the iron sheet 101 and the scraper 102 can be positioned and adjusted according to the curvature of the inner or outer arc surface, making the leveling device more stable when fixing the curvature of the iron sheet 101 and the scraper 102.

[0030] Specifically, when using the arc-shaped surface leveling device for this building: first, place the iron sheet 101 and scraper 102 on the surface of the arc-shaped surface of the building. The user holds the frame 1 and, according to the curvature of the arc-shaped surface, chooses to push the first adjusting rod group 104 or the second adjusting rod group 105. Specifically, if the arc-shaped surface of the building is an inner arc, the user simultaneously pushes the first adjusting rod 1041 and the second adjusting rod 1042 in the first adjusting rod group 104; if the arc-shaped surface of the building is an outer arc, the user simultaneously pushes the third adjusting rod 1051 and the fourth adjusting rod 1052 in the second adjusting rod group 105. When the first adjusting rod assembly 104 is pushed during use, it slides on the inner wall of the frame 1 and rotates on the surface of the fixing member 106, lifting the iron plate 101 and the scraper 102. This ensures that the curvature of the lifted iron plate 101 and scraper 102 matches the curvature of the inner arc surface of the building, facilitating the leveling of the inner arc surface of the building. If the building arc surface is an outer arc, the user pushes the second adjusting rod assembly 105, causing it to slide on the inner wall of the frame 1. When the second adjusting rod assembly 105 moves, it rotates on the surface of the fixing member 106, lifting the iron plate 101 and scraper 102. This ensures that the curvature of the lifted iron plate 101 and scraper 102 matches the curvature of the outer arc surface of the building, facilitating the leveling of the outer arc surface of the building.

[0031] After the first adjusting rod group 104 and the second adjusting rod group 105 move to the desired position, the user uses an external tool to tighten the fastening bolt 109. Under the threaded engagement of the fastening bolt 109 and the fixing screw hole 108, the rubber plug 110 moves, causing the rubber plug 110 to be inserted into the through groove 107. At this time, the friction washer 111 on the surface of the rubber plug 110 can increase the friction between the rubber plug 110 and the through groove 107, improving the reliability of the fixation. If the user does not loosen the fastening bolt 109, the rubber plug 110 and the friction washer 111 will not move out of the through groove 107, thereby fixing the position of the first adjusting rod group 104 and the second adjusting rod group 105, thus initially fixing the arc angle of the iron sheet 101 and the scraper 102.

[0032] Subsequently, the anti-slip pad 45, under normal conditions, moves away from the surfaces of the first adjusting rod assembly 104 and the second adjusting rod assembly 105, allowing the first adjusting rod assembly 104 and the second adjusting rod assembly 105 to slide smoothly on the inner wall of the frame 1. When the iron plate 101 and the scraper 102 are adjusted to the required curvature, the user tightens the fastening screw 41 on the surface of the fixing block 43. Under the action of the fastening screw 41, the fastening pressure plate 44 and the anti-slip pad 45 move, causing the fastening pressure plate 44 to move the anti-slip pad 45 to fit against the surfaces of the first adjusting rod assembly 104 and the second adjusting rod assembly 105 respectively. Under the combined action of the fastening screw 41 and the fastening pressure plate 44, the positions of the first adjusting rod assembly 104 and the second adjusting rod assembly 105 are clamped and fixed on the surface of the frame 1, so that the first adjusting rod assembly 104 and the second adjusting rod assembly 105 are clamped and fixed. 04 and the second adjusting rod group 105 will not continue to move on the inner wall of the frame 1. Under the action of the anti-slip pad 45, the friction between the fastening pressure plate 44 and the first adjusting rod group 104 and the second adjusting rod group 105 can be increased. Under the action of the anti-loosening screw sleeve 42, the fastening screw 41 is not easy to loosen during use, thereby further improving the positioning and fixing effect of the first adjusting rod group 104 and the second adjusting rod group 105. It can fix the curvature of the iron sheet 101 and the scraper 102 to realize the positioning and fixing function of the leveling device. Thus, when the leveling device is used, it can adjust the curvature of the iron sheet 101 and the scraper 102 according to the curvature of the inner or outer arc surface, making the leveling device more stable when fixing the curvature of the iron sheet 101 and the scraper 102.

[0033] Subsequently, since the user needs to hold the handle 103 for an extended period of time to operate the metal plate 101 and scraper 102, the comfort and anti-slip performance of the handle 103 surface are required to be high. The user puts the first protective cover 31 and the second protective cover 32 onto the surface of the handle 103, so that the sub-hook and loop fastener 34 on the inner wall of the second protective cover 32 adheres to the surface of the female hook and loop fastener 35 on the inner wall of the first protective cover 31. The first protective cover 31 and the second protective cover 32 are glued together by the adhesive cooperation of the female hook and loop fastener 35 and the sub-hook and loop fastener 34, thereby fitting the first protective cover 31 and the second protective cover 32 onto the surface of the handle 103. Since the inner walls of the first protective sleeve 31 and the second protective sleeve 32 are covered with adhesive, the first protective sleeve 31 and the second protective sleeve 32 can stick to the surface of the handle 103, so that the first protective sleeve 31 and the second protective sleeve 32 will not move on the surface of the handle 103. Under the action of the rubber anti-slip pad 33, the user's hand and the handle 103 can be prevented from slipping, making the grip of the handle 103 better, so as to realize the anti-slip protection function of the leveling device. This allows the leveling device to improve the construction efficiency of workers when it is used, and at the same time, it can improve the reliable grip of construction personnel and increase the stability during operation.

[0034] Subsequently, if the user uses putty or mortar to level the curved surface, the scraper 102 can be used to scrape off the excess putty or mortar, thus leveling the curved surface. However, if sanding is required, additional tools, such as a sanding plate, are needed, which limits the usability of the leveling device. In this case, the user can remove the scraper 102 from the surface of the iron sheet 101 and replace it with a sanding plate. The user loosens the mounting studs 21 on the surface of the screw hole body 22, moving them away from the scraper 102. Then, the user pulls the scraper 102, causing the mounting block 24 to move away from the mounting slot 25, thus removing the scraper 102 from the surface of the iron sheet 101. The replaced sanding plate is placed on the surface of the iron sheet 101, causing the sanding plate to engage the mounting block 24 into the corresponding mounting slot 25. Then tighten the mounting studs 21 on the surface of the mounting block 23. With the threaded engagement between the mounting studs 21 and the screw hole body 22, the abrasive plate is installed on the surface of the iron sheet 101, thereby enabling the surface of the arc-shaped surface to be abraded. At the same time, the scraper 102 can also be replaced by following the above steps, so as to realize the function of easy replacement of the leveling device. This allows the scraper 102 to be replaced with a abrasive plate to polish the arc-shaped surface when using the leveling device, making the application range of the leveling device wider and more practical, and finally completing the use of the leveling device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
