Description

Technical Field

[0001] The utility model relates to the technical field of wall construction, and specifically relates to a scraping tool for paint. Background Technique

[0002] Paint construction refers to the whole process of applying a layer of decorative or protective paint on the surface of the object to be painted. To obtain a firm paint film, paint construction usually includes four steps: substrate surface treatment, painting, curing, and paint film inspection. To make the coating firmly adhere to the surface of the substrate to be painted, the substrate must be surface-treated before painting, and the treatment method varies depending on the nature of the substrate. Interior wall paint, also called interior wall coating, includes liquid paint and powder paint. Common latex paint and wall paint belong to liquid paint. The composition of interior wall coating basically consists of water, pigments, emulsions, fillers, and various additives.

[0003] Scraping and spreading are two common process methods in paint construction. Scraping is mainly to evenly coat the paint on the surface of the substrate by using tools such as scrapers, usually applied to occasions where a thicker coating and stronger covering power are required, such as indoor and outdoor walls, etc. Spreading is to finely apply the paint on the surface of the substrate through a spreading knife to achieve a smooth and delicate effect, and is often used for fine construction such as wall repair and local decoration. The existing scraping and spreading process methods require two different scraping tools for processing, so that personnel need to often change tools for use, thus reducing the work efficiency. Content of the Utility Model

A fixed block is rotatably connected to the inner wall of the positioning connection frame. A first construction plate is fixed to the upper surface of the fixed block, and a second construction plate is fixed to the lower surface of the fixed block. A linkage slider is slidably connected to the lower surface of the limiting handle. A first piston rod is fixed to the upper surface of the linkage slider. A second piston rod is slidably connected inside the installation housing. A first magnet is fixed to the lower surface of one end of the second piston rod, and a second magnet is provided at the upper end of the positioning connection frame.

[0006] Preferably, an air guide groove is provided inside the limiting handle, and a spring is connected between the positioning connection frame and the installation housing.

[0009] With the above technical solution, the rotation of the fixing block drives the first construction plate and the second construction plate to rotate, so as to facilitate the replacement of construction tools.

[0010] Preferably, a spring is connected between the linkage slider and the limiting handle. The first piston rod is communicated with the air guide groove of the limiting handle, and the air guide groove of the limiting handle is communicated with the second piston rod.

[0011] With the above technical solution, by pressing the linkage slider, the linkage slider pushes air to the second piston rod through the first piston rod.

[0012] Preferably, the opposite ends of the first magnet and the second magnet have the same magnetic poles.

[0013] With the above technical solution, after the second piston rod is pushed by air, it drives the first magnet and the second magnet to correspond.

[0014] Preferably, a third magnet is embedded in the surface of one end of the installation housing. An opening is provided on the side surface of the positioning connecting frame, and a positioning block is slidably connected to the inner wall of the opening of the positioning connecting frame. One end of the positioning block is fixedly connected with a fourth magnet.

[0015] With the above technical solution, the third magnet attracts the fourth magnet, so that the fourth magnet drives the positioning block to slide.

[0016] Preferably, the opposite ends of the third magnet and the fourth magnet have opposite magnetic poles. A spring is connected between the positioning block and the positioning connecting frame.

Detailed implementation manners

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-6 , the present utility model provides a technical solution: a scraping tool for paint, including an installation housing 1, a limiting handle 2, an auxiliary scraper 3, a positioning connecting frame 4, a fixing block 5, a first construction board 6, a second construction board 7, a linkage slider 8, a first piston column 9, a second piston column 10, a first magnet 11, a second magnet 12, a third magnet 13, a fourth magnet 14 and a positioning block 15. The installation housing 1 has an opening on its surface. The upper surface of the installation housing 1 is fixedly connected with the limiting handle 2. An air guide groove is arranged inside the limiting handle 2. A spring is connected between the positioning connecting frame 4 and the installation housing 1. One end of the fixing block 5 penetrates through the side surface of the positioning connecting frame 4, and an adjusting turntable is arranged at one end of the fixing block 5. The first construction board 6 and the second construction board 7 are symmetrically arranged about the rotation axis center of the fixing block 5. When using this device, when the linkage slider 8 is not pressed, the positioning connecting frame 4 is pulled up by the spring on the inner wall of the installation housing 1, so that the positioning connecting frame 4 drives the fixing block 5 to slide upward. At this time, the fourth magnet 14 on one side of the fixing block 5 is attracted by the third magnet 13 on the surface of the installation housing 1, so that the fourth magnet 14 drives the positioning block 15 to slide.

[0031] The auxiliary scraper 3 is fixedly connected to the lower surface of one side of the installation housing 1. The positioning connecting frame 4 is slidably connected to the top surface of the opening of the installation housing 1. A spring is connected between the linkage slider 8 and the limiting handle 2. The first piston column 9 is communicated with the air guide groove of the limiting handle 2. The air guide groove of the limiting handle 2 is communicated with the second piston column 10. The opposite ends of the first magnet 11 and the second magnet 12 have the same magnetic poles. After the positioning block 15 is driven by the fourth magnet 14 to slide, the fixing block 5 is unlocked, which is convenient for the user to rotate the adjusting turntable at one end of the fixing block 5, so as to control the fixing block 5 to drive the first construction board 6 and the second construction board 7 to flip and replace the construction tool, improving the portability of this device and the efficiency of tool replacement.

[0032] The inner wall of the positioning connecting frame 4 is rotatably connected with a fixed block 5. The upper surface of the fixed block 5 is fixed with a first construction plate 6, and the lower surface of the fixed block 5 is fixed with a second construction plate 7. The lower surface of the limiting handle 2 is slidably connected with a linkage slider 8. One end surface of the installation shell 1 is embedded with a third magnet 13. One side surface of the positioning connecting frame 4 is provided with an opening, and the inner wall of the opening of the positioning connecting frame 4 is slidably connected with a positioning block 15. One end of the positioning block 15 is fixedly connected with a fourth magnet 14. When in use, by holding the limiting handle 2, the linkage slider 8 is pressed, and the first piston rod 9 is driven by the linkage slider 8 to push air towards the second piston rod 10. After the second piston rod 10 is pushed, the first magnet 11 is driven to correspond to the second magnet 12.

[0033] The upper surface of the linkage slider 8 is fixed with a first piston rod 9. A second piston rod 10 is slidably connected inside the installation shell 1. One end lower surface of the second piston rod 10 is fixed with a first magnet 11. A second magnet 12 is arranged at the upper end of the positioning connecting frame 4. The opposite ends of the third magnet 13 and the fourth magnet 14 have opposite magnetic poles. A spring is connected between the positioning block 15 and the positioning connecting frame 4. The vertical cross-section of the positioning block 15 is square-shaped. The positioning block 15 and the fixed block 5 form a snap connection. After the second magnet 12 is repelled by the first magnet 11, the second magnet 12 drives the positioning connecting frame 4 and the fixed block 5 to descend. At this time, the fourth magnet 14 is not restricted by the third magnet 13, so that the positioning block 15 snaps the positioning connecting frame 4 and the fixed block 5 to prevent rotation and deviation. The construction is carried out by combining the auxiliary scraper 3 with the first construction plate 6 or the second construction plate 7.

[0034] Working principle: When using the scraping tool for the paint, first, the positioning connecting frame 4 is pulled up by the spring on the inner wall of the installation shell 1, so that the fourth magnet 14 is attracted by the third magnet 13 to drive the positioning block 15 to slide, facilitating the rotation of the fixed block 5 to change the positions of the first construction plate 6 and the second construction plate 7. By holding the limiting handle 2, the linkage slider 8 is pressed, so that the linkage slider 8 drives the first piston rod 9 to move. The air is pushed towards the second piston rod 10 through the first piston rod 9, so that the second piston rod 10 drives the first magnet 11 to repel the second magnet 12. The positioning connecting frame 4 and the fixed block 5 are driven to descend by the second magnet 12 and cooperate with the auxiliary scraper 3 to work, increasing the overall practicability.
