Description

Technical Field

[0001] This application relates to the technical field of scraper tools, and in particular to a heatable scraper tool for automotive film application. Background Technology

[0002] The automotive film squeegee is an indispensable core tool in the process of applying automotive film. It is mainly used to tightly adhere the film to the glass or car body surface, while expelling internal air and moisture, so as to achieve a smooth film application. Its working principle is to use uniform squeegee pressure to make the adhesive between the film and the substrate fully contact and cure, ultimately achieving a seamless bond.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following defects: In the existing technology, the hot air output components of the existing scraper tools with heating functions are mostly fixed installation structures without automatic angle adjustment functions. Since the surface of different car models has various curved shapes, the hot air at a fixed angle cannot evenly cover the construction area with different curvatures, resulting in some areas of the film surface not being effectively heated and softened. During scraping, bubbles and wrinkles are easily formed between the film surface and the car body, and it is difficult to correct them with a single scraping, which can easily lead to problems such as film edge warping and gaps. Utility Model Content

[0004] In order to allow for the adjustment of the nozzle angle, this application provides a heated scraper tool for automotive film application.

[0005] This application provides a heatable scraper tool for automotive film application, which adopts the following technical solution: it includes a handle, a fixed box is fixedly connected to the bottom of the handle, and a scraper is provided at the contact point of the inner wall of the fixed box; A connecting frame is fixedly connected to the back of the fixed box, a heating fan is fixedly connected to the back of the connecting frame, a limit ring is fixedly connected to the bottom of the heating fan, a nozzle is provided below the limit ring, an electric push rod is fixedly connected to the inner wall of the connecting frame, and a connecting block is provided below the electric push rod.

[0006] Optionally, the front of the fixing box is provided with a sliding groove, a pressing block is slidably connected to the inner wall of the sliding groove, a moving plate is fixedly connected to the back of the pressing block, and a triangular fixing block is fixedly connected to the back of the moving plate.

[0007] Optionally, the scraper has a snap-fit ​​groove on its front side, a slide rail is fixedly connected to the top of the inner wall of the fixing box, a sliding block is slidably connected to the outer wall of the slide rail, and a rotating wheel is rotatably connected to the front of the sliding block.

[0008] Optionally, the outer wall of the rotating wheel contacts the back of the triangular fixing block, a snap-fit ​​block is fixedly connected to the bottom of the sliding block, the outer wall of the snap-fit ​​block snaps into the inner wall of the snap-fit ​​groove, a spring telescopic column is fixedly connected to the right side of the sliding block, and there are two sliding blocks.

[0009] Optionally, the two sliding blocks are symmetrically arranged, with the left side of the right sliding block fixedly connected to the right side of the spring telescopic column. There are two triangular fixing blocks, which are symmetrically arranged. There are also two rotating wheels, which are symmetrically arranged.

[0010] Optionally, a rotating block is rotatably connected to the inner wall of the limiting ring, the bottom of the rotating block is fixedly connected to the top of the nozzle, and a push rod is fixedly connected to the bottom output end of the electric push rod.

[0011] Optionally, the bottom of the push rod is fixedly connected to the top of the connecting block, and a connecting plate is rotatably connected to the outer wall of the connecting block, with the left side of the connecting plate fixedly connected to the right side of the rotating block.

[0012] Optionally, the number of connecting plates is two, and the two connecting plates are symmetrically arranged with the connecting block as the center, and the nozzle is trapezoidal.

[0013] In summary, this application includes the following beneficial technical effects: 1. This utility model, by incorporating components such as an electric push rod, a connecting block, and a connecting plate, enables the electric push rod to drive the connecting plate to rotate via the push rod and connecting block, thereby driving the rotating block to rotate along the inner wall of the limiting ring. This allows for flexible adjustment of the nozzle angle, precisely adapting to construction areas with different curvatures on the vehicle body or directly heating the scraper to ensure that hot air always covers the scraping area. Combined with the scraper's scraping pressure, this creates a synergistic effect of heating and scraping, further improving the tightness of the film adhesion and avoiding problems such as film edge warping and gaps.

[0014] 2. This utility model uses components such as a pressing block, rotating wheels, and sliding blocks to press the pressing block on the front of the fixing box. The two triangular fixing blocks then press the two rotating wheels, causing the two sliding blocks to move and disengage the two locking blocks from the locking groove of the scraper, thus completing the scraper disassembly. After releasing the pressing block, the spring telescopic column resets and pushes the sliding blocks back, allowing the locking blocks to automatically engage with the locking groove of the new scraper for fixation. The entire replacement process requires no auxiliary tools, can quickly adapt to scrapers of different materials and sizes, meets diverse construction needs, and avoids wear and tear on the connecting structure caused by tool disassembly, extending the overall service life of the tool.

[0017] The following is in conjunction with the appendix Figures 1-4 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0018] This application discloses a heatable scraper tool for automotive film application. For example... Figure 1 , Figure 4 As shown, it includes a handle 1, a fixed box 11 is fixedly connected to the bottom of the handle 1, and a scraper 12 is provided at the contact point of the inner wall of the fixed box 11.

[0019] In this embodiment, a connecting frame 3 is fixedly connected to the back of the fixed box 11, and a heating fan 31 is fixedly connected to the back of the connecting frame 3. A limit ring 311 is fixedly connected to the bottom of the heating fan 31, and a nozzle 321 is provided below the limit ring 311. The nozzle 321 has a diffused spray pattern to increase its heating range. An electric push rod 34 is fixedly connected to the inner wall of the connecting frame 3, and a connecting block 35 is provided below the electric push rod 34.

[0020] Please see Figure 4 As shown, a rotating block 32 is rotatably connected to the inner wall of the limiting ring 311. A through groove is provided inside the rotating block 32 so that the hot air generated by the heating fan 31 can be delivered to the nozzle 321. The bottom of the rotating block 32 is fixedly connected to the top of the nozzle 321. A push rod 341 is fixedly connected to the bottom output end of the electric push rod 34.

[0021] Please see Figure 2 As shown, the front of the fixed box 11 has a sliding groove, and a pressing block 2 is slidably connected to the inner wall of the sliding groove. A movable plate 21 is fixedly connected to the back of the pressing block 2. The movable plate 21 can prevent the pressing block 2 from disengaging from the sliding groove. A triangular fixing block 211 is fixedly connected to the back of the movable plate 21.

[0022] Please see Figure 4As shown, the bottom of the push rod 341 is fixedly connected to the top of the connecting block 35, and a connecting plate 33 is rotatably connected to the outer wall of the connecting block 35. The left side of the connecting plate 33 is fixedly connected to the right side of the rotating block 32.

[0023] Please see Figure 3 As shown, the scraper 12 has a snap-fit ​​groove 22 on the front side, and a slide rail 23 is fixedly connected to the top of the inner wall of the fixed box 11. A sliding block 231 is slidably connected to the outer wall of the slide rail 23. The sliding block 231 is restricted by the slide rail 23 and can only move laterally, making its movement smoother. A rotating wheel 232 is rotatably connected to the front of the sliding block 231.

[0024] Please see Figure 4 As shown, there are two connecting plates 33, which are symmetrically arranged with the connecting block 35 as the center, and the nozzle 321 is trapezoidal.

[0025] Please see Figure 3 As shown, the outer wall of the rotating wheel 232 contacts the back of the triangular fixing block 211. The rotating wheel 232 reduces the friction between it and the triangular fixing block, thus improving the service life of the device. A snap-fit ​​block 24 is fixedly connected to the bottom of the sliding block 231. The outer wall of the snap-fit ​​block 24 snaps into the inner wall of the snap-fit ​​groove 22. A spring telescopic column 25 is fixedly connected to the right side of the sliding block 231. There are two sliding blocks 231, which are symmetrically arranged. The left side of the right sliding block 231 is fixedly connected to the right side of the spring telescopic column 25. There are two triangular fixing blocks 211, which are symmetrically arranged. There are two rotating wheels 232, which are symmetrically arranged.

[0026] The implementation principle of the heatable scraper tool for automotive film application in this embodiment is as follows: When the scraper 12 needs to be replaced, the operator presses the pressing block 2 on the front of the fixing box 11 with their finger. The pressing block 2 moves into the box along the sliding groove of the fixing box 11, simultaneously driving the moving plate 21 on its back and the two symmetrically arranged triangular fixing blocks 211 to move in the same direction. During the movement of the triangular fixing blocks 211, their inclined surfaces contact and squeeze the rotating wheel 232 on the front of the sliding block 231, forcing the rotating wheel 232 to rotate around its own axis. At the same time, it pushes the two symmetrical sliding blocks 231 to move to both sides along the slide rail 23 on the inner wall of the fixing box 11. When the sliding blocks 231 move, they compress the spring telescopic column on the right side. 25. Gradually disengage the locking block 24 at the bottom of the sliding block 231 from the locking groove 22 on the front of the scraper 12. Once the locking block 24 is completely disengaged from the locking groove 22, the old scraper 12 can be pulled out from the inner wall of the fixing box 11 to complete the disassembly. Take a suitable new scraper 12, align its edge with the mounting groove on the inner wall of the fixing box 11, and push it in. Release the pressing block 2, and the compressed spring telescopic column 25 releases its elastic potential energy, pushing the sliding blocks 231 on both sides to move in opposite directions along the slide rail 23. The sliding blocks 231 drive the locking block 24 to move synchronously until the locking block 24 is completely embedded in the locking groove 22 of the new scraper 12. At this time, the triangular fixing block 211 is affected by the reaction force of the sliding block 231 and the rotating wheel 232. The lower moving plate 21 resets, the pressing block 2 springs back to its initial position, and the scraper 12 is fixed. Before construction, the heating fan 31 is started. The hot air generated by the heating fan 31 enters the rotating block 32 through the air outlet at its bottom. The hot air is transported through the channel inside the rotating block 32 to the trapezoidal nozzle 321 at its bottom. The wide air outlet of the trapezoidal nozzle 321 blows the hot air evenly onto the surface of the car film, heating and softening the film surface, reducing the hardness of the film surface and improving adhesion. When the construction area is a curved surface of the car body, such as the corner of the window, the waistline of the car body, or when the scraper 12 needs to be directly heated, the electric push rod 34 on the inner wall of the connecting frame 3 drives the push rod 341 to move up and down in the vertical direction. When the push rod 341 moves, it synchronously drives the connecting block 35 at its bottom to move. The two connecting plates 33 symmetrically connected to the outer wall of the connecting block 35 rotate around the axis of the connecting block 35 as the connecting block 35 moves. The left side of the connecting plate 33 is fixedly connected to the rotating block 32. Therefore, when the connecting plate 33 rotates, it drives the rotating block 32 to rotate along the inner wall of the limiting ring 311. The rotating block 32 drives the trapezoidal nozzle 321 at the bottom to rotate synchronously, thereby adjusting the angle of the nozzle 321. When the angle of the nozzle 321 is adapted to the curved surface of the construction area, the electric push rod 34 is turned off. The nozzle 321 maintains the current angle and continues to deliver hot air. The construction personnel hold the handle 1 to control the scraper 12 to scrape along the membrane surface, thus completing the tight adhesion between the membrane surface and the vehicle body.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
