[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a car film scraper capable of switching Rockwell hardness, such as Figure 1-Figure 4 As shown, it includes a main body plate 1, and a detachable scraper 2 is installed on both sides of the main body plate 1. Slots 11 are set on both sides of the main body plate 1. A positioning plate 21 is installed on one side of the detachable scraper 2. The positioning plate 21 is plugged into the slot 11. The main body plate 1 includes two upper and lower plates. Locking holes 13 are set at both ends of the upper and lower plates. Locking bolts 14 are installed in the locking holes 13. The locking bolts 14 lock and fix the detachable scraper 2. The design of the detachable scraper 2 on both sides of the main body plate 1 enables technicians to quickly replace scrapers with different hardness or wear according to actual needs. The installation and fixation of the scraper can be completed by simple plug-in and locking operations, which greatly improves work efficiency. The plug-in cooperation between the positioning plate 21 and the slot 11, and the tightening effect of the locking bolt 14, ensure the stability and reliability of the scraper during use, and avoid the scraper from shaking or falling off during use. Since the scraper is detachable, scrapers of different hardness and materials can be equipped as needed to adapt to different types and specifications of car films, as well as film application work of different parts and difficulty. When the scraper is worn or damaged, it can be easily replaced with a new one without replacing the entire tool, reducing maintenance costs and usage costs. The entire replacement process does not require special tools and can be completed with simple operations, making it easy for technicians to master and improving the convenience of operation.

[0025] In this embodiment, the removable scrapers 2 on both sides of the main plate 1 are one hard scraper and the other soft scraper. The Rockwell hardness of the hard scraper is 50-90, and the Rockwell hardness of the soft scraper is 30-50, so that scrapers with different Rockwell hardness can be installed as needed.

[0026] Specifically, the upper and lower inner walls of the slot 11 are provided with grooves 12 , and the upper and lower surfaces of the positioning plate 21 are provided with convex strips 22 , which are engaged with the grooves 12 to ensure the positioning of the detachable scraper 2 .

[0027] Furthermore, a positioning notch 212 is provided on the positioning plate 21 near the locking bolt 14 , and the positioning notch 212 is clamped on the outer wall of the locking bolt 14 to ensure that the detachable scraper 2 is locked and fixed.

[0028] Furthermore, a magnet block 15 is installed between the middle parts of the upper and lower plates of the main body plate 1. Since most cars are made of steel, the magnet block 15 can be used to absorb the film on the car for positioning when applying the film, so as to quickly find the working position after the work is interrupted. A notch 211 is provided on the positioning plate 21 near the magnet block 15. The notch 211 is stuck on the outer wall of the magnet block 15. The notch 211 is in the shape of a semicircular notch, which is used to avoid escaping the magnet block 15 and at the same time enhances the stability of the detachable scraper 2 and the main body plate 1.

[0029] Furthermore, the thickness of the detachable scraper 2 gradually decreases from the side close to the main plate 1 to the side far away from the main plate 1, ensuring that the outer side is thinner and can effectively scrape off the bubbles in the film.

[0030] Furthermore, the outer corners of the detachable scraper 2 are arc-shaped structures to ensure rounded edges and avoid damage to the film.

[0031] Furthermore, the upper and lower surfaces of the outer side of the main body plate 1 are provided with outwardly protruding reinforcing ribs to improve the strength of the main body plate 1 .

[0032] When the utility model of the automobile film scraper with switchable Rockwell hardness is used, the scraper is firstly composed of a main body plate 1 and a detachable scraper plate 2 in terms of structure. The main body plate 1 is a key supporting structure, and the slots 11 arranged on both sides thereof are used to install the detachable scraper plate 2. The grooves 12 on the upper and lower inner walls of the slots 11 match the convex strips 22 on the positioning plate 21 installed on one side of the detachable scraper plate 2, ensuring that the scraper plate can be stably inserted and fixed on the main body plate 1.

[0033] When the technician needs to use a scraper, he first selects a suitable detachable scraper according to the material of the film and the required scraper hardness. For example, for a harder car film, a hard scraper with a Rockwell hardness in the range of 50-90 can be selected; and for a soft car film, a soft scraper with a Rockwell hardness in the range of 30-50 can be selected.

[0034] During the installation process, the technician aligns the positioning plate 21 of the selected removable scraper 2 with the slot 11 on the main plate 1, and gently pushes it in so that the convex strip 22 and the groove 12 are engaged and matched, completing the preliminary positioning. Subsequently, the technician rotates the locking bolt 14 so that it passes through the locking holes 13 at both ends of the upper and lower plates of the main plate 1 and fits tightly against the positioning notch 212 of the positioning plate 21, thereby firmly locking the removable scraper 2 on the main plate 1. During this process, the notch 211 on the positioning plate 21 will smoothly engage with the outer wall of the magnet block 15 in the middle of the main plate 1, ensuring smooth installation.

[0035] During use, the technician holds the main plate 1 and uses the installed detachable scraper 2 to scrape the car film flat to remove bubbles and ensure that the film is flat and wrinkle-free. The outer side of the scraper is designed to be thinner and the edge is rounded, which can effectively remove bubbles and avoid damage to the film.

[0036] When the scraper needs to be replaced, the technician only needs to loosen the locking bolt 14 to easily remove the current detachable scraper 2 and install a new scraper. The whole process is simple and fast, which greatly improves work efficiency. This design not only meets the needs of different film pasting, but also reduces maintenance costs and usage costs, allowing technicians to easily master and efficiently complete the film pasting work.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
