Description

Technical Field

[0001] The utility model relates to the technical field of automobile film pasting, in particular to an automobile film pasting positioning tool. Background Technique

[0002] The body film is attached to the car paint surface through a polymer composite material to achieve the purpose of protecting the original paint and decorating the vehicle body, and can be easily removed at any time, in sharp contrast to traditional paint surface chemical changes such as glazing, coating, and painting. The automobile body film is a high-performance, low-viscosity polyvinyl chloride film specially designed for automobile body film pasting, with the property of fully conforming to various base material surfaces of the car body paint and interior. It has many advantages such as being more convenient for construction, stronger flexibility, durability, chemical corrosion resistance, and light impermeability. It can effectively ensure accurate, seamless, and bubble-free pasting when facing the curved car body surface during the construction process, and will not damage the car paint. On the contrary, it will fully protect the original paint of the vehicle.

[0003] Before pasting the body film, it is necessary to first fix the film auxiliary on the vehicle body and cut the film according to the vehicle body size. In the prior art, most of them directly use a magnetic handle to adsorb the film on the vehicle body. Since the film is prone to slide relative to the magnetic handle during the adsorption process, the positioning effect of the film will be poor. Therefore, improvements need to be made.

[0004] The existing patent (application number: CN202221661713.9) proposes an automobile film pasting positioning tool, including a rubber magnet; by adopting a rubber magnet, a convex part one is arranged in the middle part of the rubber magnet, and a convex part two is arranged at the corresponding position on the rubber seat, the characteristics of the rubber magnet are successfully used to replace the traditional magnetic handle. This design enables the tool to better adapt to various curved surfaces of the vehicle body, so that the rubber magnet can be more tightly adsorbed on the vehicle body, providing a good basis for the preliminary positioning of the film.

[0005] However, in the actual film pasting operation process, the existing design still has some obvious defects and deficiencies; in order to facilitate the operator to smoothly adsorb the rubber magnet on the vehicle body, the current design usually sets a handle on the rubber magnet. Although the presence of the handle does facilitate the initial adsorption operation, the subsequent problem is that when the rubber magnet is successfully adsorbed on the vehicle body, the handle will extend vertically relative to the vehicle body. In the actual operation process of film pasting, due to the relatively narrow film pasting space and the need for the operator to perform delicate operations around the vehicle body, it is inevitable to touch these protruding handles. Such touching is extremely likely to cause deviation in the position fixed by the rubber magnet, thus destroying the originally accurately set film pasting positioning points. This position deviation will not only affect the overall effect of the film pasting, increase the difficulty and time cost of film pasting, but also may cause quality problems such as wrinkles and bubbles in the film.

[0006] In view of this, the present application is hereby proposed. Summary of the Utility Model
