Description

Technical Field

[0001] This utility model relates to the field of building plastering trowel technology, specifically a building plastering trowel. Background Technology

[0002] Plastering is a traditional decorative process involving the application of mortar to the walls, floors, ceilings, and other surfaces of buildings. In some regions of my country, it is also called "whitewashing" or "plastering." Plastering refers to the systematic construction process of applying plastering mortar to the surface of the base material, serving to protect the substrate and enhance aesthetics, providing specific functions for the building. Plastering has two main functions: first, protection, protecting walls from wind, rain, and snow erosion, increasing the wall's moisture resistance, weathering resistance, and heat insulation capabilities, and improving the wall's durability and thermal performance; second, aesthetics, improving indoor hygiene, purifying the air, beautifying the environment, and enhancing living comfort. Plastering requires the use of a plastering trowel.

[0003] A plastering trowel disclosed in Chinese Utility Model Patent Application Publication CN221422567U, although it features a grout storage chamber and an injection port on the trowel body, where cement mortar is stored and pushed to the injection port by a pressing plate, eliminating the need for workers to bend over to collect the mortar, thus simplifying the process and improving efficiency, has several drawbacks. The injection port is relatively small, making the grouting process complex and inefficient, and the operation is difficult and inconvenient. Furthermore, it is difficult to spread the mortar evenly, resulting in poor mortar distribution during actual use. Additionally, the trowel requires pressing the upper part of the pressing button, which often leads to finger pain after repeated use, significantly increasing the risk of injury to the operator. Therefore, a plastering trowel is urgently needed to address these shortcomings. Utility Model Content

[0032] Example 2

[0033] This utility model provides the following technical solution: A handle 11 is fixedly connected to the upper surface of the slurry storage chamber 5. A pressing rod 12 is rotatably connected to the inner wall of the handle 11. A fifth spring 29 is fixedly connected to the upper surface of the pressing rod 12. One end of the fifth spring 29 is fixedly connected to the inner top wall of the handle 11. A first sliding groove 13 is provided on the inner wall of the pressing rod 12.

One end of the second spring 15 is fixedly connected to the inner wall of the first sliding groove 13. A locking tooth is fixedly connected to the outer surface of the first limiting block 14. The locking tooth engages with the inner wall of the first limiting groove 17. A lifting column 16 is inserted into the inner wall of the handle 11. A limiting plate is fixedly connected to the upper end of the lifting column 16. The upper end of the fourth spring 22 abuts against the lower surface of the limiting plate. The lower end of the lifting column 16 penetrates the upper surface of the slurry storage chamber 5. The lower end of the lifting column 16 is fixedly connected to the upper surface of the extrusion plate 23. The two sides of the outer surface of the lifting column 16 are respectively provided with a first limiting groove 17 and a second limiting groove 18. The inner side wall of the handle 11 is provided with a second sliding groove 19. The inner side wall of the second sliding groove 19 is slidably connected with a second limiting block 20. The outer surface of the second limiting block 20 is fixedly connected with a third spring 21. One end of the third spring 21 is fixedly connected to the inner side wall of the second sliding groove 19. The outer surface of the second limiting block 20 is fixedly connected with a limiting tooth. The outer surface of the limiting tooth is engaged with the inner side wall of the second limiting groove 18. The upper surface of the handle 11 is located outside the lifting column 16 and is fixedly connected with a fourth spring 22. The inner side wall of the slurry storage chamber 5 is slidably connected with an extrusion plate 23. The lower surface of the shovel body 1 is provided with a slurry outlet hole 28.

[0034] To facilitate easier and less strenuous mortar extrusion, as shown in the attached document... Figures 1 to 7 As shown, this application adopts the following structure. Through the arrangement of the extrusion rod 12, the first limiting block 14, the lifting column 16, the first limiting groove 17, the second limiting groove 18, and the second limiting block 20, the plastering trowel achieves the effect of easily and effortlessly squeezing out mortar. In actual use, after the mortar is poured into the mortar storage chamber 5, the left end of the extrusion rod 12 is squeezed upwards by holding the handle 11. At this time, the extrusion rod 12 rotates along the hinge with the handle 11, and the teeth on the outer surface of the inner side wall of the first sliding groove 13 at its right end will engage with the inside of the first limiting groove 17. When the right end of the extrusion rod 12 moves downwards, it drives the lifting column 16 to move downwards, thereby driving the extrusion plate 23 to squeeze the mortar in the mortar storage chamber 5, forcing the mortar to be squeezed out from the inside of the mortar outlet 28. During this process, after releasing the extrusion rod 12, the fifth spring 29 will restore the extrusion rod 12 to its original position. Furthermore, when the extrusion rod 12 rotates to its limit, the fifth spring 29 will then... The three springs 21 push the second limiting block 20 toward the lifting column 16, so that the limiting teeth on the outer surface of the second limiting block 20 engage with the second limiting groove 18, preventing the lifting column 16 from being bounced upward by the fourth spring 22. When the extrusion plate 23 is extruded to the lowest point, the mortar is used up. Then, the second limiting block 20 is moved to the right, so that the limiting teeth on the outer surface of the second limiting block 20 disengage from the engagement with the second limiting groove 18. The lifting column 16 is lifted upward by the elastic force of the fourth spring 22, so that mortar can be injected into the mortar storage chamber 5 again for use. That is, through the cooperation of the extrusion rod 12, the first limiting block 14, the lifting column 16, the first limiting groove 17, the second limiting groove 18 and the second limiting block 20, during use, the end of the extrusion rod 12 can be squeezed by the handle 11 with multiple fingers, thereby pushing the lifting column 16 downward. The lever principle makes it easier and less strenuous to squeeze out the mortar.

[0035] Example 3

[0036] The present invention provides the following technical solution: A hand buckle 24 is rotatably connected to the inner wall of the handle 11 via a shaft; an end cap 25 is rotatably connected to the outer surface of the right end of the slurry storage chamber 5; an arc-shaped connecting rod 26 is fixedly connected to the outer surface of the end cap 25; a second connecting rod 27 is rotatably connected to one end of the arc-shaped connecting rod 26 via a shaft; one end of the second connecting rod 27 is rotatably connected to the lower end of the hand buckle 24 via a shaft; a figure-eight spring is provided on the outer surface of the shaft of the hand buckle 24; and the two ends of the figure-eight spring are fixedly connected to the outer surface of the hand buckle 24 and the inner wall of the handle 11, respectively.

[0037] To facilitate the injection of mortar into the grout storage cavity 5, as shown in the attached... Figures 1 to 7As shown, this application adopts the following structure: through the arrangement of the handle 24, end cap 25, arc-shaped connecting rod 26, and second connecting rod 27, the plastering trowel is designed to facilitate the pouring of mortar into the grout storage cavity 5. In actual use, when pouring mortar into the grout storage cavity 5, the handle 24 can be pulled by the finger. At this time, the handle 24 will rotate along the hinge with the handle 11. The second connecting rod 27 pulls the upper end of the arc-shaped connecting rod 26 to move upward, thereby causing the end cap 25 to rotate along the hinge with the grout storage cavity 5. This opens the end cap 25 outward, allowing the mortar to flow out of the grout storage cavity 5. The mortar is poured into the slurry storage chamber 5 from the right end. After use, it is also convenient to clean the inside of the slurry storage chamber 5. After the slurry is poured, the hand buckle 24 is automatically returned to its original position by the figure-eight spring on the rotating shaft of the hand buckle 24, which drives the end cover 25 to cover the right end of the slurry storage chamber 5, and it can be used. That is, through the cooperation of the hand buckle 24, the arc-shaped connecting rod 26 and the second connecting rod 27, the end cover 25 can be opened by directly pulling the hand buckle 24 during use, and then mortar can be poured into the slurry storage chamber 5 from the end cover 25, which achieves the purpose of facilitating the pouring of mortar into the slurry storage chamber 5.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
