Description

Technical Field

[0001] This utility model relates to the field of self-tapping screw technology, specifically to a self-tapping screw structural connector with anti-loosening effect. Background Technology

[0002] Screws are common fasteners that play a crucial role in many fields such as daily life, industrial production, and construction. They tightly connect different components through the interaction of their threads, ensuring the stability and reliability of the structure. Self-tapping screws, on the other hand, are screws that can be directly screwed into the connected parts without pre-tapping. The threads of self-tapping screws have a unique design; the tooth profile is usually sharper and finer than that of ordinary screws, and the pitch is larger. This design allows them to more easily cut into softer materials such as wood, plastic, and thin metal sheets when screwed in. When using a self-tapping screw, a rotational force is applied using a tool, causing the screw to rotate. Due to the sharp threads and tip design, during rotation, the threads gradually cut into the material of the connected parts, simultaneously squeezing the material outwards to form internal threads that match the screw's threads. As the screw continues to screw in, the threads mesh with each other, generating a tightening force that tightly connects two or more components together. However, existing self-tapping screws do not offer anti-loosening features, have poor stability, and are prone to falling off during trial use, making them inconvenient to use. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a self-tapping screw structure connector with anti-loosening effect, including a main body 10, a nut 20, a slot 201, a washer 30, a protrusion 301, a groove 40, and a drainage groove 401; This self-tapping screw structure enhances friction and prevents loosening during use. The specific implementation method is as follows: A nut 20 is fixedly connected to one end of the main body 10, and a slot 201 is embedded in the surface of the nut 20. A washer 30 is fixedly connected to one side of the surface of the nut 20, and protrusions 301 are fixedly installed at equal intervals on the bottom of the washer 30. A groove 40 is embedded in the surface of the nut 20, and a drainage groove 401 is installed at the end of the groove 40. The main body 10 and the nut 20 are integrated into one piece, and the bottom of the main body 10 is set as a pointed cone shape. The nut 20 is set as a rounded corner structure, and the rounded corner structure of the nut 20 and the slot 201 are located on the same side. The groove 201 is hexagonal and is embedded in the top surface of the nut 20. The washer 30 is annular and is installed at the bottom of the nut 20. The protrusion 301 is semi-circular and is located at the bottom of the washer 30. The groove 40 is located at the bottom of the groove 201 and is connected to the groove 40. The drainage groove 401 is embedded between the main body 10 and the nut 20 and is located at the end of the drainage groove 401 through the surface of the main body 10. The vertical section of the drainage groove 401 is inclined.

[0022] Simultaneously, the main body 10 is moved by hand, so that the pointed conical end of the main body 10 moves to the mounting surface, and the auxiliary mounting structure is inserted into the slot 201. At this time, the auxiliary mounting structure is rotated, so that the auxiliary mounting structure drives the nut 20 to rotate through the slot 201, so that the nut 20 drives the main body 10 to rotate, so that the main body 10 rotates into the mounting surface. At the same time, the nut 20 drives the washer 30 to move downward, and the washer 30 drives the protrusion 301 to move downward, so that the bottom of the protrusion 301 moves to the surface of the mounting surface. At this time, the nut 20 squeezes the washer 30 and the protrusion 301, so that the washer 30 and the protrusion 301 contract, which increases the friction between the nut 20 and the mounting surface. After the self-tapping screws are installed, the auxiliary mounting structure is pulled out from the slot 201. Liquid locking adhesive is then injected into the groove 40, allowing it to pass through the groove 40 and into the drainage groove 401. The adhesive slides downwards along the slope of the drainage groove 401, moving to the surface of the main body 10 and into the gap between the mounting surfaces of the main body 10. Working principle: When using this self-tapping screw structure connector with anti-loosening effect, the washer 30, the protrusion 301, the groove 40 and the drainage groove 401 are set to enhance the friction of the connector, prevent it from being detached, and increase the overall practicality.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
