Description

Technical Field

[0001] This invention relates to the field of automotive repair technology, specifically a heat-free self-adhesive for dent repair. Background Technology

[0002] In the field of automotive dent repair, traditional methods involve melting hot glue with a caulking gun, applying it to a shim, attaching it to the dent, and then using tools to pull the dent out. Later, some discovered the use of cold gel, which eliminates the need for heating the adhesive; it can be applied directly to the shim by hand. However, its effectiveness is limited to thinner, shallower dents, and it's cumbersome with a low success rate. This is because the adhesive easily drips onto the car's sheet metal, preventing the use of higher viscosity adhesives; the adhesive also tends to detach and leave residue, limiting the use of stronger adhesives; each application requires manual application, which is time-consuming and laborious; and the shim is prone to detaching during work, hindering rapid and continuous operation.

[0003] Therefore, those skilled in the art have provided a heat-free self-adhesive for repairing dents to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a heat-free self-adhesive for repairing dents, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A heat-free self-adhesive for dent repair includes a self-adhesive body, which is composed of a pull head, a connecting rod, pressure-sensitive adhesive, and a gasket body. The gasket body is embedded inside the pressure-sensitive adhesive, and the upper end of the gasket body is fixedly connected to the connecting rod, which is provided with a pull head at its upper end.

[0007] As a further aspect of the present invention: the zipper head is configured as a cylindrical structure, and the surface of the cylinder is provided with vertical anti-slip textures.

[0008] As a further embodiment of the present invention: the pressure-sensitive adhesive is configured as a disc-shaped structure, and the gasket body is completely enclosed within it.

[0009] Instructions for using the heat-free self-adhesive dent repair adhesive: Apply the self-adhesive to the dented area of ​​the car, engage the pull head with the matching pull rod, and quickly pull the pull rod to pull the entire self-adhesive, creating an outward pulling force on the dented area and thus repositioning and repairing it. The self-adhesive can be used without heating, and this application uses a stronger pressure-sensitive adhesive. When subjected to external impact, the greater the force, the stronger the adhesion and the greater the pulling force generated.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. When using, stick the self-adhesive to the dented area of ​​the car, connect the pull head to the matching pull rod, and pull the pull rod quickly and forcefully to pull the entire self-adhesive, thereby creating an outward pulling force on the dented area of ​​the car and thus restoring and repairing the dented area; the self-adhesive of this application can be used without heating, and this application uses a pressure-sensitive adhesive with stronger adhesion. When the pressure-sensitive adhesive is subjected to external impact, the greater the force, the stronger the adhesion and the greater the pulling force generated.

[0012] 2. While maintaining sufficient adhesion, it prevents adhesive residue from remaining on the vehicle's sheet metal; the upper end of the gasket body is fixedly connected to the pull head via a connecting rod, making it less likely to be thrown away during operation and significantly improving work efficiency.

[0013] 3. This application does not require manual application of adhesive; the finished product can be used immediately upon opening the packaging. It can provide stronger tensile strength because, due to the physical properties of pressure-sensitive adhesive, the stronger the tensile strength, the greater the adhesion. It is not easy to detach during operation because there is adhesive on both sides, which not only adheres to the recessed area but also wraps around the main body of the gasket. The upper end of the main body of the gasket is fixedly connected to the pull head via a connecting rod, making it less likely to be thrown away during operation and greatly improving work efficiency. The main body of the gasket is completely wrapped by the pressure-sensitive adhesive, making it difficult for the main body of the gasket to fall off. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-2 In this embodiment of the invention, a heat-free self-adhesive for dent repair includes a self-adhesive body, which is composed of a pull head 1, a connecting rod 2, a pressure-sensitive adhesive 3, and a gasket body 4. The gasket body 4 is embedded inside the pressure-sensitive adhesive 3, and the upper end of the gasket body 4 is fixedly connected to the connecting rod 2. The upper end of the connecting rod 2 is provided with a pull head 1.

[0019] The zipper 1 is configured as a cylindrical structure, and the surface of the cylinder is provided with vertical anti-slip textures.

[0020] The pressure-sensitive adhesive 3 is configured as a disc-shaped structure, and the gasket body 4 is completely enclosed inside it. During manufacturing, the pressure-sensitive adhesive is melted and poured onto the gasket, so that the pressure-sensitive adhesive wraps around the gasket body, and both sides of the gasket body are adhesive, forming a certain thickness of pressure-sensitive adhesive on both sides of the gasket body. The pressure-sensitive adhesive is a super-strong pressure-sensitive adhesive, allowing the pressure-sensitive adhesive and the gasket body to be deeply integrated.

[0021] In use, the self-adhesive is applied to the dented area of ​​the car, the pull head engages with the matching pull rod, and by quickly pulling the pull rod, the entire self-adhesive is pulled, creating an outward pulling force on the dented area, thus repositioning and repairing it. This self-adhesive does not require heating and uses a stronger pressure-sensitive adhesive. The greater the force of the impact, the stronger the adhesion and the greater the pulling force generated. While maintaining sufficient adhesion, it prevents adhesive residue from remaining on the car's sheet metal. The upper end of the gasket body is fixedly connected to the pull head via connecting rod 2, preventing it from being thrown away during operation and significantly improving work efficiency.

[0022] This application requires no manual application of adhesive; the finished product can be used immediately upon opening the packaging. It provides stronger tensile strength because, due to the physical properties of pressure-sensitive adhesive, the stronger the tensile strength, the greater the adhesion. It is not easy to detach during operation because there is adhesive on both sides, which not only adheres to the recessed area but also wraps around the main body of the gasket. The upper end of the main body of the gasket is fixedly connected to the pull head via connecting rod 2, making it less likely to be thrown away during operation and greatly improving work efficiency. The main body of the gasket is completely wrapped by the pressure-sensitive adhesive, making it difficult for the main body of the gasket to fall off.
