[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 6 The present invention provides a technical solution: a cup-shaped internal locking drawing rivet, including a cup-shaped main body 1. A drawing column 2 is fixedly connected to the top of the cup-shaped main body 1. Engaging teeth 3 are fixedly connected to the side surface of the drawing column 2. A breaking groove 4 is provided on the side surface of the drawing column 2 and is located below the breaking groove 4. An expanding nail body 5 is fixedly connected to the bottom of the cup-shaped main body 1. The working principle of the cup-shaped internal locking drawing rivet mainly involves its unique structure and installation process. The following is a detailed explanation of its working principle. The cup-shaped internal locking drawing rivet mainly consists of a cup-shaped main body 1, an internal locking mechanism, and a drawing part. The cup-shaped main body 1 provides the main connection area and support structure. The internal locking mechanism ensures the stability after the rivet is installed, and the drawing part is the key to driving the internal locking mechanism during installation.

[0020] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, a shrinking nail body 6 is fixedly connected to the bottom of the expanding nail body 5. A fixed block 7 is fixedly connected to the top of the shrinking nail body 6 and is located in the inner cavity of the expanding nail body 5. A convex buckle 8 is fixedly connected to the side of the fixed block 7 away from the shrinking nail body 6. Striped patterns 9 are fixedly connected to the inner cavity of the expanding nail body 5. During the installation process, corresponding holes are pre-drilled in the two materials to be connected. The cup-shaped main body 1 part of the cup-shaped internal locking drawing rivet is aligned and placed into the holes. Using a special riveting gun or other tools, the drawing part is pulled. This action will trigger the internal locking mechanism, causing the shrinking nail body 6 to change from the locked state to the unlocked state. While the drawing part is being pulled, the shrinking nail body 6 part will gradually expand in the expanding nail body 5 until it is completely inserted into the hole.

[0021] In this embodiment, as Figure 4 、 Figure 5 and Figure 6As shown, a clamping block 10 is fixedly connected to the bottom of the cup-shaped main body 1. The clamping block 10 is fixedly connected to the inner cavity of the expansion nail body 5. A concave-shaped clamping groove 11 is formed in the inner cavity of the clamping block 10. The concave-shaped clamping groove 11 is located in the inner cavity of the expansion nail body 5. The working principle of the internal locking mechanism: The internal locking mechanism is the core part of the cup-shaped internal locking wire drawing rivet. When the wire drawing part is pulled, the convex buckle 8 structure in the internal locking mechanism will be pulled, allowing the convex buckle 8 part of the rivet to be smoothly inserted into the concave-shaped clamping groove 11. When the wire drawing part is released, the components in the internal locking mechanism will be stuck in the concave-shaped clamping groove 11 and locked on the inner wall of the hole. This locking mechanism ensures that the rivet will not loosen or fall off after connection.

[0022] The usage method and advantages of the present utility model: When using this cup-shaped internal locking wire drawing rivet, the working process is as follows:

[0023] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the working principle of the cup-shaped internal locking wire drawing rivet mainly involves its unique structure and installation process. The following is a detailed explanation of its working principle. The cup-shaped internal locking wire drawing rivet mainly consists of a cup-shaped main body 1, an internal locking mechanism, and a wire drawing part. The cup-shaped main body 1 provides the main connection area and support structure. The internal locking mechanism ensures the stability of the rivet after installation, and the wire drawing part is the key to driving the internal locking mechanism during installation. During the installation process, corresponding holes are pre-drilled on the two materials to be connected. Align the cup-shaped main body 1 part of the cup-shaped internal locking wire drawing rivet and place it into the hole. Use a special riveting gun or other tools to pull the wire drawing part. This action will trigger the internal locking mechanism, causing the shrinkage nail body 6 to change from the locked state to the unlocked state. While the wire drawing part is being pulled, the shrinkage nail body 6 part will gradually expand in the expansion nail body 5 until it is completely inserted into the hole. The working principle of the internal locking mechanism: The internal locking mechanism is the core part of the cup-shaped internal locking wire drawing rivet. When the wire drawing part is pulled, the convex buckle 8 structure in the internal locking mechanism will be pulled, allowing the convex buckle 8 part of the rivet to be smoothly inserted into the concave-shaped clamping groove 11. When the wire drawing part is released, the components in the internal locking mechanism will be stuck in the concave-shaped clamping groove 11 and locked on the inner wall of the hole. This locking mechanism ensures that the rivet will not loosen or fall off after connection.
