[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] The embodiment of the present application discloses a paving scraping tool with freely adjustable thickness. Figure 1 The base 1 is composed of a plurality of roller legs 5, each of which is foldable and retractable, and a plurality of roller legs 5 are installed on the lower surface of the base 1 near the four hanging corners. The roller legs 5 can be folded and retracted when not in use or when the scraping tool is transported, thereby reducing the occupied space and making the storage and transportation of the scraping tool more convenient. The base 1 is movably supported by the roller legs 5, and the scraping plate 6 is moved horizontally by pushing the base 1 to scrape the mortar on the tiles. There is no need to manually control the thickness of the mortar, so that the thickness of the mortar after scraping is more accurate, and the mortar can be more evenly distributed, thereby having a better scraping effect.

[0036] Reference Figure 1The lower end edge of the scraper 6 is set to be serrated. The serrated structure is convenient for scraping, so that after scraping, dense grooves are formed on the upper surface of the mortar on the tile, which is more conducive to the adhesion of the mortar to the tile when it is installed. A handle 3 is fixedly installed on the upper surface of the base 1, and the handle 3 is convenient for gripping when using the scraper tool, and a telescopic rod 4 is installed in the middle part of the handle 3. The lower end of the telescopic rod 4 is fixedly connected to the lifting frame 2, and the lifting frame 2 is slidably installed on the handle 3. The lower side of the lifting frame 2 clamps and fixes the upper end of the scraper 6. By adjusting the telescopic rod 4, the height of the lifting frame 2 can be adjusted to achieve the height adjustment of the scraper 6, so that the mortar of different thicknesses can be scraped, which has good flexibility in use.

[0037] Reference Figure 2 The lifting frame 2 includes a lifting rod 21 arranged horizontally, and the lifting rod 21 has guide openings 24 near the left and right ends. When the lifting rod 21 is installed on the handle 3, the guide openings 24 on the left and right sides are respectively mounted on the support rods 31 on the left and right sides. The support rods 31 cooperate with the guide openings 24 to guide the lifting rod 21 to move up and down. The lower side of the lifting rod 21 is fixed with two front and rear clamping plates 22, and the outer side of the clamping plate 22 on one side is threaded with multiple tightening screws 23. The lifting rod 21 uses the clamping plates 22 on the front and rear sides to clamp the upper end of the scraper plate 6 in the middle, and then tighten the multiple tightening screws 23 to tighten it on the scraper plate 6 to clamp and fix the scraper plate 6. The distance between the two clamping plates 22 is greater than the thickness of the scraper plate 6. The scraper plate 6 is conveniently replaced by the clamping plates 22 and the tightening screws 23. It can meet the replacement of different scraper plates 6 and better meet the different scraping needs.

[0038] Reference Figure 3 The telescopic rod 4 includes a sleeve rod 41, an adjusting rod 43 is inserted at the lower end of the sleeve rod 41, and a first adjusting screw 42 is installed on the outer side of the sleeve rod 41 near the lower end. The adjusting rod 43 is inserted on the inner side of the sleeve rod 41 to achieve telescopic adjustment, and the sleeve rod 41 guides the adjusting rod 43 during telescopic adjustment, and uses the first adjusting screw 42 to lock and fix the adjusted adjusting rod 43. A connecting plate 44 is fixed to the lower end of the adjusting rod 43, and the connecting plate 44 is fixed to the lifting rod 21 by screws to achieve a fixed connection between the telescopic rod 4 and the lifting frame 2.

[0039] Reference Figure 4The handle 3 includes a horizontal grip rod 32, and a vertical support rod 31 is fixed to the lower side of the grip rod 32 near the left and right ends, and the lower end of the support rod 31 is fixedly inserted on the base 1, and the grip rod 32 is fixed to the upper surface of the base 1 by using two support rods 31, and the support rod 31 fixes and supports the grip rod 32, and a fixing sleeve 33 is fixed to the middle part of the lower side of the grip rod 32, and a fixing screw 34 is installed on the outer thread of the fixing sleeve 33. The grip rod 32 uses the fixing sleeve 33 to position the upper end of the telescopic rod 4 and uses the fixing screw 34 to lock and fix the upper end of the fitted telescopic rod 4. Fixing the telescopic rod 4 by using the fixing sleeve 33 and the fixing screw 34 is convenient for the later disassembly of the telescopic rod 4, and is also convenient for the disassembly and maintenance of the lifting frame 2.

[0040] Reference Figure 5 A guide opening 12 is provided in the middle of the upper surface of the base 1, and the base 1 uses the guide opening 12 to achieve the giving and guiding of the scraper plate 6 when adjusting it up and down, and mounting sleeves 11 are fixed to the upper surface of the base 1 near the left and right ends. The outer thread of the mounting sleeve 11 is threaded with a locking screw 13. The base 1 inserts the support rod 31 on the grip rod 32 through the provided mounting sleeve 11, and tightens the support rod 31 through the locking screw 13 to complete the installation and fixation of the support rod 31.

[0041] Reference Figure 6 The roller leg 5 includes a leg 53, a roller 54 is fixed at the lower end of the leg 53, and a fixing plate 51 is provided at the upper end of the leg 53. The fixing plate 51 has through holes near both ends, and screws fixed to the base 1 are inserted through the through holes. The through holes opened in the fixing plate 51 are used to insert screws and are fixed to the base 1 by screws, thereby realizing the installation and fixation of the roller leg 5 on the base 1. A rotating bracket 52 rotatably connected to the leg 53 is fixed to the lower side of the fixing plate 51. The leg 53 is rotatably mounted on the fixing plate 51 through the rotating bracket 52, thereby realizing the rotatable installation of the leg 53 on the lower side of the base 1, thereby realizing the deployment support and folding and retracting of the leg 53, and the outer side of the rotating bracket 52 is threadedly mounted with a second adjusting screw 55 for tightening and fixing the leg 53. By screwing the second adjusting screw 55, it is tightened on the leg 53 to lock and fix the deployed or folded leg 53.

[0042] The implementation principle of the paving scraper tool with freely adjustable thickness in the embodiment of the present application is as follows: when scraping the mortar applied on the ceramic tile, the ceramic tile is placed on the ground or on a platform, and then the mortar is applied on the ceramic tile. At this time, the roller legs 5 on the base 1 are unfolded to a vertical state, and then the second adjusting screw 55 is tightened on the legs 53 to lock and fix. At this time, the scraper tool is placed on the ground or on a platform, and then the adjusting rod 43 on the telescopic rod 4 is telescopically adjusted according to the required mortar thickness. The telescopically adjustable adjusting rod 43 has The lifting rod 21 is moved up and down, and the lifting rod 21 drives the scraper 6 to adjust the height. After the height adjustment of the scraper 6 is completed, the adjusting rod 43 is locked by screwing the first adjusting screw 42, and then the gripping rod 32 is pushed forward to move the lower end of the scraper 6 on the tile to scrape off the excess mortar on the tile, thereby completing the scraping process of the mortar on the tile. When not in use, the support legs 53 are folded and retracted, and the support legs 53 are fixed by the second adjusting screw 55, so that the scraping tool can be stored or transported.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
