Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0026] Embodiment 1

[0027] As Figures 1 to 4As shown in the figure, this embodiment proposes a squeegee for the construction of externally bonded carbon fiber cloth reinforcement engineering, which includes a housing 1. On the opposite inner side walls of the housing 1, there are rotatably connected rotating rods 11. On the outer side wall of the rotating rod 11, there is fixedly connected a squeegee 12. On the upper surface of the housing 1, there is fixedly connected a grip 13. On the inner top wall of the housing 1, there is slidably connected a U-shaped plate 2. On the inner side wall of the U-shaped plate 2, there is slidably connected a cleaning plate 21. At the bottom of the cleaning plate 21, there is opened a through groove corresponding to the squeegee 12. On the inner side wall of the U-shaped plate 2, there is rotatably connected a rotating cylinder 22. On the side of the rotating cylinder 22 away from the U-shaped plate 2, there is rotatably connected a connecting rod 23. One end of the connecting rod 23 away from the rotating cylinder 22 is movably hinged to the cleaning plate 21. On the outer side wall of the housing 1, there is rotatably connected a turning handle 24. One end of the turning handle 24 penetrates the housing 1 and is fixedly connected to the rotating rod 11.

[0028] On the top of the U-shaped plate 2, there are fixedly connected two T-shaped long blocks 4. On the inner top wall of the housing 1, there is opened a T-shaped groove 41 corresponding to the T-shaped long blocks 4. The U-shaped plate 2 is slidably connected to the T-shaped groove 41 through the T-shaped long blocks 4. By setting the sliding connection between the two T-shaped long blocks 4 and the T-shaped groove 41, the U-shaped plate 2 is clamped to the housing 1 through the horizontal ends of the T-shaped long blocks 4, so that the U-shaped plate 2 can move along the direction of the T-shaped groove 41 on the inner top wall of the housing 1; On both sides of the cleaning plate 21, there are fixedly connected cleaning blocks 5. The cleaning blocks 5 are arranged in a U shape. The sides of the cleaning blocks 5 away from the cleaning plate 21 are both inclined. By setting the cleaning blocks 5, the cleaning plate 21 can impact and scrape the adhesive through the cleaning blocks 5. Under the action of the inclined surfaces of the cleaning blocks 5, the impact effect of the cleaning plate 21 on the adhesive is increased; On the outer side wall of the U-shaped plate 2, there is fixedly connected a micro motor 3. The output end of the micro motor 3 penetrates the side wall of the U-shaped plate 2 and is rotatably connected to the rotating cylinder 22. By controlling the micro motor 3 to drive the rotating cylinder 22 to rotate rapidly on the inner side wall of the U-shaped plate 2, the rotating cylinder 22 can drive the cleaning plate 21 to perform rapid reciprocating motion inside the U-shaped plate 2 through the connecting rod 23; On both sides of the cleaning plate 21, there are fixedly connected T-shaped short blocks 6. On both sides of the U-shaped plate 2, there are opened rectangular grooves 61. The horizontal ends of the T-shaped short blocks 6 penetrate the rectangular grooves 61. The vertical ends of the T-shaped short blocks 6 are slidably connected to the outer side wall of the U-shaped plate 2. By setting the sliding connection between the T-shaped short blocks 6 and the rectangular grooves 61, the cleaning plate 21 is slidably connected to the outer side wall of the U-shaped plate 2 through the vertical ends of the two T-shaped short blocks 6, preventing the cleaning plate 21 from shifting to both sides of the U-shaped plate 2; On the side of the U-shaped plate 2 away from the rotating cylinder 22, there is fixedly connected a pull rod 7. On the side of the housing 1 close to the pull rod 7, there is opened a sliding groove. The pull rod 7 is slidably connected to the sliding groove. By pulling the pull rod 7, the pull rod 7 can drive the cleaning plate 21 and the cleaning blocks 5 to move towards the squeegee 12 inside the housing 1 through the U-shaped plate 2.

[0029] In this embodiment, turning the handle 24 drives the rotating rod 11 to rotate. The rotating rod 11 drives the scraping plate 12 to rotate 180 degrees, so that the end of the scraping plate 12 with the adhesive moves to the inside of the housing 1. Start the micro-motor 3. The micro-motor 3 drives the rotating cylinder 22 to rotate through the output end. Under the limiting action of the T-shaped short block 6 and the rectangular groove 61, the rotating cylinder 22 drives the cleaning plate 21 to reciprocate inside the U-shaped plate 2 through the connecting rod 23. The cleaning plate 21 drives the cleaning block 5 to reciprocate. By pulling the pull rod 7, the U-shaped plate 2 moves along the chute towards the scraping plate 12. When the U-shaped plate 2 drives the cleaning plate 21 and the cleaning block 5 to pass above the scraping plate 12, under the action of the inclined surface of the cleaning block 5, its blade impacts the adhesive on the top of the scraping plate 12, so that the cleaning block 5 repeatedly impacts and scrapes the adhesive at the same position on the top of the scraping plate 12, improving the scraping effect of the cleaning block 5. By pulling the pull rod 7, during the process that the U-shaped plate 2 passes above the scraping plate 12 once, multiple scraping treatments of the top of the scraping plate 12 are completed, enhancing the scraping effect on the adhesive, thereby improving the cleaning efficiency.

[0030] Embodiment 2

[0031] As Figures 1 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the grip 13 includes a fixed rod 8. The fixed rod 8 is fixedly connected to the upper surface of the housing 1. A telescopic handle 81 is slidably sleeved on the outer side wall of the fixed rod 8. A through groove is formed on the side wall of the fixed rod 8. The fixed rod 8 is slidably connected with two clamping blocks 82 through the through groove. A return spring 83 is fixedly connected between the two clamping blocks 82. A number of through holes adapted to the clamping blocks 82 are formed on the outer side wall of the telescopic handle 81.

[0032] In this embodiment, by pressing the clamping blocks 82 on both sides of the telescopic handle 81, the two clamping blocks 82 move towards each other along the through groove and separate from the telescopic handle 81. Pull the telescopic handle 81 to move upward along the fixed rod 8. Under the elastic action of the return spring 83 itself, the return spring 83 pushes the two clamping blocks 82 to move towards both sides of the telescopic handle 81 through the through holes. Under the limiting action of the clamping blocks 82, the position of the telescopic handle 81 is fixed, so as to adjust the distance between the telescopic handle 81 and the housing 1, and the length of the grip 13 can be adjusted under different working conditions.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
