Description

Technical Field

[0001] The utility model relates to the technical field of fasteners in hardware components, in particular to a hexagon socket screw with an anti-disassembly component. Background Art

[0002] The cylindrical head hexagon socket screw, also known as the hexagon socket bolt, cup head screw, and hexagon socket screw, has different names, but the meaning is the same. The commonly used hexagon socket head screws are 4.8, 8.8, 10.9, and 12.9. It is also called a hexagon socket screw, also called a hexagon socket bolt. Its head is a hexagon socket head and a cylindrical head. According to the material, there are stainless steel and iron. Stainless steel has stainless steel SUS202 hexagon socket head screws, which is a common stainless steel material. There are stainless steel SUS304 hexagon socket head screws and stainless steel SUS316 hexagon socket head screws. Iron is divided according to the strength grade of the hexagon socket head screw, including 4.8 hexagon socket head screws, 8.8 hexagon socket head screws, 10.9 hexagon socket head screws, and 12.9 hexagon socket head screws. Hexagon socket head screws of grade 8.8-12.9 are high-strength and high-grade hexagon socket bolts. Generally, when electronic products are damaged by non-human factors during the warranty period, they can be sent back to the original manufacturer for free repair. In order to identify whether consumers have disassembled electronic products by themselves, manufacturers need to design corresponding preventive measures to avoid incurring additional repair costs.

[0003] The application number is 201220154678.1, which discloses a screw, a screwdriver and a screw and screwdriver assembly with anti-disassembly function. The screw comprises: a column, a threaded structure is formed on the surface of the column; a cap body, the cap body is arranged at one end of the column, and the cap body forms a recessed space on an end face relative to the column; and an abutment structure, the abutment structure is arranged in the recessed space of the cap body, the abutment structure comprises: a plurality of groups of first abutment surfaces, a plurality of groups of second abutment surfaces and a plurality of groups of third abutment surfaces; a superimposed curve of each of the second abutment surfaces and the corresponding first abutment surface extends from a top edge of the recessed space to a bottom surface of the recessed space, and each of the second abutment surfaces has an upper area and a lower area; each of the third abutment surfaces is formed between the side of the corresponding first abutment surface and the adjacent second abutment surface. The utility model can effectively prevent users from disassembling screws using traditional hexagonal wrenches.

[0004] The above-mentioned document discloses a screw, a screwdriver, and a screw and screwdriver assembly with an anti-dismantling function, which have the following defects: the anti-dismantling method of the screw, the screwdriver, and the screw and screwdriver assembly with an anti-dismantling function is mostly to design a relatively complex driving groove at the center position of the screw head. This type of anti-dismantling screw has a complex process, is difficult to process, has a high cost, and is also large in size, so it is not suitable for fixing smaller and more precise instruments and equipment, and the anti-dismantling screw can still be disassembled using special tools.

[0005] It can be seen from this that the anti-dismantling screws of this type of device have complex processing, are difficult to process, have high cost, and are large in size, making them unsuitable for fixing smaller and more precise instruments and equipment. It is necessary to improve the existing deficiencies and provide a hexagon socket screw with an anti-dismantling component. Utility Model Content
