Technical Field
[0001] This utility model relates to the field of electronic injection molded structural components, and more specifically, to 3C electronic injection molded structural components with pre-embedded metal nuts. Background Technology
[0002] 3C electronic injection-molded structural components refer to plastic parts manufactured through injection molding, primarily used in computer, communication, and consumer electronics products, serving mechanical functions such as support, protection, fixation, and connection. In existing injection-molded structural component connections, most components are connected via bolts and nuts. However, nuts added later can loosen when bolts are removed, and repeated disassembly may damage the nuts themselves, leading to decreased connection stability. Utility Model Content

When the bolt engages with the metal nut, the position and orientation of the metal nut remain unchanged, achieving a stable connection. At the same time, the inclined conical surface always contacts the inner wall of the connecting ring, making the metal nut fit more closely to the inner wall of the connecting ring during the engagement of the bolt and reducing damage caused by friction, thereby improving the durability of the metal nut.

[0024] The beneficial effects of adopting the above technical solution are as follows: When producing the injection-molded structural part 1, the metal nut 3 is first embedded inside the connecting ring 2, so that the metal nut 3 contacts the inner wall of the connecting ring 2 through the first circumferential groove 4 and the second circumferential groove 5, so that the connecting ring 2 and the metal nut 3 are engaged. When the bolt engages with the metal nut 3, the position and direction of the metal nut 3 remain unchanged, so that the connection has a stable effect. At the same time, the inclined conical surface 6 always contacts the inner wall of the connecting ring 2, so that the metal nut 3 fits more closely to the inner wall of the connecting ring 2 during the engagement of the bolt and reduces the damage caused by friction, thereby improving the durability of the metal nut 3.
[0025] The connecting block 11 is a cylinder, and the barb 12 is located on the outside of the connecting block 11, while the barb 12 is located at the top of the connecting block 11.
[0026] The beneficial effects of adopting the above technical solution are: the main function of the barb 12 is to form a reliable connection by interlocking with the corresponding opening on another component, making the connection more stable.
[0027] Among them, there are four reinforcing blocks 13 installed on the outside of the connecting block 11. The four reinforcing blocks 13 are distributed around the bottom of the connecting block 11, and all four reinforcing blocks 13 are fixedly connected to the connecting strip 10.
[0028] The beneficial effects of adopting the above technical solution are: the four reinforcing blocks 13 reinforce the bottom of the connecting block 11, making the overall toughness of the connecting block 11 stronger and preventing it from being squeezed and broken.
[0029] There are multiple reinforcing ribs 7, which are distributed around the connecting ring 2 and are irregular in shape.
[0030] The beneficial effect of adopting the above technical solution is that multiple reinforcing ribs 7 are integrally connected with the first support block 9, which makes the first support block 9 and the connecting ring 2 close to each other and support each other, further improving the structural strength.
[0031] Among them, a positioning post 14 is fixedly installed on the top of the injection molded structural component 1. The positioning post 14 is cross-shaped.
[0032] The beneficial effects of adopting the above technical solution are: the positioning post 14 itself is part of the plastic structure. When it is inserted into the corresponding hole of another component, it forms an additional support point, which can enhance the rigidity of the overall assembly and reduce the deformation of the component when it is squeezed or bent.
[0033] The injection molded structural component 1 has a locking block 15 fixedly installed inside, a second positioning pin 16 fixedly installed on the top of the injection molded structural component 1, and a second support block 17 fixedly installed on the outside of the second positioning pin 16.

[0037] The metal nut 3 is cylindrical in shape, and the first circumferential groove 4 and the second circumferential groove 5 divide the metal nut 3 into three circumferential edges 19.
[0038] The beneficial effects of adopting the above technical solution are: the interior of the first circumferential groove 4 and the second circumferential groove 5 are both embedded in the inner wall of the connecting ring 2, and the first circumferential groove 4 and the second circumferential groove 5 cooperate with three circumferential ridges 19, so that the component can be disassembled multiple times after being connected with the bolt without damaging the metal nut 3. Furthermore, since the metal nut 3 remains fixed, the connectivity of the structure is improved and the overall strength is increased.
[0039] Working principle and usage process of this utility model: Firstly, a connecting ring 2 is fixedly installed on the top of the injection-molded structural part 1. A metal nut 3 is embedded inside the connecting ring 2. The metal nut 3 has a first circumferential groove 4, a second circumferential groove 5, and an inclined conical surface 6. When the injection-molded structural part 1 is produced, the metal nut 3 is first pre-embedded inside the connecting ring 2, so that the metal nut 3 contacts the inner wall of the connecting ring 2 through the first circumferential groove 4 and the second circumferential groove 5, so that the connecting ring 2 and the metal nut 3 are engaged. When a bolt is engaged with the metal nut 3, the position and direction of the metal nut 3 remain unchanged, so as to achieve a stable connection. Meanwhile, the tapered surface 6 is always in contact with the inner wall of the connecting ring 2, so that the metal nut 3 fits the inner wall of the connecting ring 2 better during the engagement of the metal nut 3 and the bolt, and reduces the damage caused by friction, thereby improving the durability of the metal nut 3. Secondly, since a connecting block 11 is fixedly installed above the connecting strip 10, and a barb 12 is fixedly installed on the outside of the connecting block 11, the barb 12 interlocks with the corresponding opening on another component to form a reliable connection, making the connection more stable. Finally, since a locking block 15 is fixedly installed inside the injection molded structural component 1, and a second positioning pin 16 is fixedly installed on the top of the injection molded structural component 1, and a second support block 17 is fixedly installed on the outside of the second positioning pin 16, the locking block 15 is engaged with another component to make the two ends fit together. At the same time, the second positioning pin 16 is inserted into the interior of the other end component to limit the connection between the two ends. Meanwhile, the second support block 17 supports the second positioning pin 16, thereby strengthening the structure of the second positioning pin 16 and maintaining the stability of the connection.
