Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of scraping knives, in particular to a long-handled floor paint scraping knife. Background Art
[0002] Floor paint is resistant to water and other corrosive media and has very good physical and mechanical properties of the coating.
[0003] When laying floor paint, workers need to use a scraper to smooth the floor paint. Most scrapers are a flat surface fixed with a handle to form a smoothing tool. Since the handle is short, workers need to squat on the ground to operate when using it. Crouching for too long will cause the operator's physical strength to decrease, which will affect work efficiency.
[0004] According to the existing technology, although some scraping knives on the market have added long-handled grips, which allow operators to stand and perform smoothing work, the increase in the force arm requires increased control force when moving. The increase in force will make it difficult to control the flow direction of the floor paint during the scraping process, which will cause the floor paint to flow too fast and the flow range to be too large, easily exceeding the range where the floor paint needs to be laid, and it is difficult to control the smoothing of the floor paint. When standing and laying, the visual distance between the staff and the scraping knife becomes far, the operator cannot effectively observe the bottom of the scraping knife, and cannot effectively control the flow of the floor paint during the operation, thereby failing to ensure the quality of the finished product of the floor paint laying. Utility Model Content
[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.
[0006] To this end, the technical solution adopted by the utility model is: a long-handled floor paint scraper, comprising a scraping plate, the top of the scraping plate is symmetrically fixedly connected with a fixed block, one side of the fixed block is rotatably connected with a rotating ring, one side of the rotating ring is fixedly connected with a rotating ring, the top of the rotating ring is rotatably connected with a rotating rod, one end of the rotating rod is fixedly connected with a first bevel gear, both sides of the first bevel gear are meshed with second bevel gears, a threaded rod is fixedly connected at the center position of one side of the second bevel gear, one end of the threaded rod is threadedly connected to the rotating ring in a through-shape, one end of the threaded rod is fixedly connected with a moving block, one end of the moving block is fixedly connected with a stopper, the bottom of the scraping plate is fixedly connected with a scraper, and one side of the scraping plate is symmetrically fixedly connected with a cleaning mechanism.
[0007] Preferably, the cleaning mechanism comprises a connecting block, one side of the connecting block is rotatably connected to a rotating rod, one end of the rotating rod is fixedly connected to a worm, and one side of the worm is meshingly connected to a worm gear.
[0008] Preferably, one end of the worm gear is fixedly connected to a third bevel gear, one side of the third bevel gear is meshingly connected to a fourth bevel gear, and a rotating shaft is fixedly connected to a center position of one side of the fourth bevel gear.
[0009] Preferably, one end of the rotating shaft is fixedly connected to a first gear, one side of the first gear is meshingly connected to a second gear, and a reciprocating screw is fixedly connected to a center position of one side of the second gear.
[0010] Preferably, one end of the reciprocating screw is threadedly connected to a threaded block, the bottom of the threaded block is fixedly connected to a cleaning block, and the cleaning block is slidably connected to the surface of the scraper.
[0011] Preferably, a connecting sleeve is fixedly connected to the top of the rotating ring, one end of the connecting sleeve is slidably connected to a telescopic tube in a penetrating manner, and the rotating rod is rotatably connected to the inner wall of the telescopic tube in a penetrating manner.
[0012] Preferably, a control handle is fixedly connected to the outer wall of the telescopic tube.
[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:
[0014] 1. The utility model is provided with a scraper and a stopper. The first bevel gear can be controlled to rotate by rotating the rotating rod, and then the second bevel gears on both sides are driven to rotate. During the rotation, the threaded rod can be controlled to rotate and then the stopper of the moving block can be controlled to move. In this way, the flow range of the floor paint can be limited when the scraper is performing the leveling work, avoiding the floor paint flow range being too large and difficult to control, thereby ensuring the leveling quality of the floor paint.
[0015] 2. A cleaning block is provided in the utility model. When the scraper is performing the leveling work, the floor paint will solidify over time, and the solidified floor paint will adhere to the scraper, which will cause the leveling ability of the scraper to be weakened. After the leveling is reduced, the floor paint may not be leveled, which will cause the floor paint to be uneven. However, the cleanliness of the scraper can be maintained after cleaning with the cleaning block, thereby ensuring the flatness of the floor paint during laying. BRIEF DESCRIPTION OF THE DRAWINGS
