[0029] With the popularization and development of intelligent terminal products, the safety protection of their internal core components has become an important issue. Traditional screws are easily disassembled by unauthorized personnel, resulting in an increased risk of product theft or data leakage. Therefore, there is an urgent need in the market for a new type of anti-disassembly and anti-theft screw and its disassembly tool that can effectively prevent illegal disassembly and is also convenient for regular maintenance.

[0030] In view of this, an embodiment of the utility model provides a screw assembly and a disassembly tool, which can reduce the possibility of the screw being disassembled by unauthorized personnel. A unique locking part is designed on the screw head, which makes it impossible for conventional screwdrivers and other tools to be inserted or effectively rotated. At the same time, the matching special disassembly tool has a mating part that precisely matches the locking part, ensuring that only authorized personnel can easily perform disassembly operations.

[0031] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, a screw assembly 10 proposed in an embodiment of the utility model includes:

[0033] Screw head 11;

[0034] The screw tail 12 is connected to the screw head 11 and has a thread on its outer surface for assembling the target product; and

[0035] The locking portion 13 is arranged on the side of the screw head 11 away from the screw tail 12, and at least two locking portions 13 are evenly spaced around the axis of the screw head 11, wherein at least two locking portions 13 are rotated simultaneously to generate torque to drive the screw head 11 to rotate.

[0036] In the technical solution adopted in this embodiment, the screw head 11 provides an overall structural frame for the screw assembly 10 to ensure the strength of the screw assembly 10. The screw tail 12 is fixedly connected to the screw head 11 and is an important component of the entire screw assembly 10. The thread arranged on the outer surface of the screw tail 12 can meet the connection or fixation between the target product components. The locking portion 13 arranged on the side of the screw head 11 away from the screw tail 12 can effectively reduce the possibility of the screw assembly 10 being illegally disassembled by unauthorized personnel. It can be understood that at least two locking portions 13 are evenly arranged around the axis of the screw head 11, and at least two locking portions 13 are rotated at the same time to generate a torque that can drive the screw head 11 to rotate, so that conventional tools such as screwdrivers can be difficult to insert or effectively rotate. The technical solution proposed in the embodiment of the utility model reduces the possibility of the screw assembly 10 being illegally disassembled by unauthorized personnel by designing a unique locking portion 13 on the screw head 11, thereby effectively protecting the target product.

[0037] Specifically, the screw assembly 10 includes a screw head 11 , a screw tail 12 and a locking portion 13 .

[0038] The screw head 11 is mainly used to provide an overall structural frame of the screw assembly 10 to ensure structural strength, have a certain load-bearing capacity, and provide support.

[0039] The screw tail 12 is fixedly connected to the screw head 11. The outer surface of the screw tail 12 is provided with threads, which can synchronously rotate the screw head 11 when the screw head 11 is driven to rotate by external force, so as to be connected or fixed to the target product through its own threads.

[0040] The locking portion 13 is mainly used to lock the screw assembly 10, making it difficult for conventional screwdrivers and other tools to be inserted or effectively rotated, thereby reducing the possibility of illegal disassembly of the screw assembly 10. In this embodiment, the locking portion 13 can be arranged on the side of the screw head 11 away from the screw tail 12, and the locking portion 13 can be provided as two or more. Only when at least two locking portions 13 are acted upon by external forces at the same time can a torque be generated to drive the screw assembly 10 to rotate, thereby ensuring that the screw assembly 10 is disassembled by the matching special disassembly tool 20, thereby reducing the possibility of illegal disassembly.

[0041] Further, see Figure 1 In one embodiment of the present invention, the number of the locking parts 13 is three.

[0042] In the technical solution adopted in this embodiment, the number of locking parts 13 is set to 3. The design of three locking parts 13 can provide stronger fixing force, making disassembly more difficult and increasing safety. In addition, the three locking parts 13 are evenly arranged around the axis of the screw head 11, which helps to disperse the force more evenly, reduce local stress concentration, and improve stability. Compared with setting more locking parts 13, the design of three locking parts 13 simplifies the design and manufacturing process, and reduces design complexity and potential errors.

[0043] Further, see Figure 1 In one embodiment of the present invention, the locking portion 13 is configured as a locking hole.

[0044] In the technical solution adopted in this embodiment, the locking portion 13 is configured as a locking hole. The annular hole design allows the matching special disassembly tool 20 to be aligned, and even if it is not aligned at the first time, it can be matched with any locking hole by slightly rotating it, thereby improving the efficiency of alignment, thereby improving the disassembly efficiency and reducing the difficulty of operation.

[0045] Further, see Figure 1 In one embodiment of the present invention, the diameter of the locking hole is 0.3 mm to 1.2 mm; and / or,

[0046] The depth of the locking hole is 0.1mm to 1mm.

[0047] In the technical solution adopted in this embodiment, the numerical range of the aperture of the locking hole is set to 0.3 mm to 1.2 mm. That is, the size of the locking hole is small, making it difficult for general tools to be inserted. Even if something made of general materials gets in, it will break or bend easily due to insufficient hardness and cannot achieve torque, reducing the possibility of the screw assembly 10 being illegally disassembled. And the numerical range of the depth of the locking hole is set to 0.1 mm to 1 mm. That is, the depth of the locking hole is shallow, making it difficult for general tools to apply force and easy to slip out, further reducing the possibility of the screw assembly 10 being illegally disassembled. Therefore, when disassembling, at least two locking holes need to be stressed simultaneously to achieve rotation.

[0048] Furthermore, referring to Figure 1 , in an embodiment of the present invention, the material of the screw head 11 is steel or alloy; and / or,

[0049] the material of the screw tail 12 is steel or alloy.

[0050] In the technical solution adopted in this embodiment, using steel or alloy to make the screw assembly 10 can enhance the anti-destruction ability. It can be understood that the screw assembly 10 is heat-treated, so that the locking hole is not easily damaged during the locking process, and the situation of not being tightly locked or unable to be disassembled can be reduced.

[0051] The present invention also provides a disassembly tool 20 for disassembling and assembling the screw assembly 10. The disassembly tool 20 includes a body 21 and a mating part 22 provided at the end of the body 21. Among them, the mating part 22 is used to cooperate with the locking part 13 to drive the screw head 11 to rotate.

[0052] In the technical solution adopted in this embodiment, the body 21 can be disassembled and stored at will and can be installed on the handle of a manual screwdriver or an electric screwdriver. The mating part 22 is provided at the end of the body 21 and corresponds to the locking part 13, and is used to cooperate with the locking part 13, so as to be able to drive the screw assembly 10 to rotate under the action of an external force. In this embodiment, the mating part 22 can be a cylindrical cutter head. At the same time, the position of the cylindrical cutter head is in circular alignment with the locking hole. When performing disassembly or installation work, the cylindrical cutter head is inserted into the locking hole, and a rotational force is applied to the body 21 through the handle, so that the locking hole can rotate synchronously with the cylindrical cutter head, and then the screw assembly 10 can rotate.

[0053] Furthermore, referring to Figure 2 , in an embodiment of the present invention, the mating part 22 and the body 21 are integrally formed.

[0054] In the technical solution adopted in this embodiment, the mating portion 22 and the body 21 are integrally formed. Such a setting can reduce the number of components, simplify the overall design, and reduce design complexity. At the same time, the number of connection points between components is reduced, thereby reducing potential failure points and improving the reliability of the disassembly tool 20. Moreover, the integral structure is usually more robust and can provide better stability and durability.

[0055] Furthermore, referring to Figure 2 , in an embodiment of the present utility model, a groove 23 is provided around one end of the body 21 facing away from the mating portion 22 for increasing torque.

[0056] In the technical solution adopted in this embodiment, a groove 23 is provided around one end of the body 21 facing away from the mating portion 22. It can be understood that by setting it in this way, when the body 21 is installed on the handle of a manual screwdriver or an electric screwdriver, the groove 23 can ensure that the handle of the manual screwdriver or the electric screwdriver can correctly cooperate with the body 21, providing sufficient torque to tighten or loosen the screw assembly 10, while reducing the risk of sliding or damaging the body 21. The groove 23 can be provided as one or multiple, and is not limited herein.

[0057] Furthermore, referring to Figure 2 , in an embodiment of the present utility model, the disassembly tool 20 further includes a limiting portion 24 provided on the outer surface of the body 21 and located on the side of the groove 23 close to the mating portion 22 for restricting the rotation of the disassembly tool 20 after installation.

[0058] In the technical solution adopted in this embodiment, through the provided limiting portion 24, when the body 21 is installed on the handle of a manual screwdriver or an electric screwdriver, the body 21 can be limited, reducing the possibility of sliding and increasing reliability. It can be understood that a recess corresponding to the limiting portion 24 is provided on the handle of the manual screwdriver or the electric screwdriver, and the recess can cooperate with the limiting portion 24, so that synchronous rotation can be achieved during the disassembly work. In this embodiment, the limiting portion 24 can be a limiting protrusion or a limiting block, and is not limited herein.

[0059] Furthermore, referring to Figure 1 、 Figure 2 , in an embodiment of the present utility model, the disassembly tool 20 further includes a magnetic attraction device provided on the mating portion 22 for attracting the locking portion 13.

[0060] In the technical solution adopted in this embodiment, the disassembly tool 20 further includes a magnetic attraction device. The magnetic attraction device is provided on the mating portion 22 to conveniently suck the screw assembly 10 through the adsorption force of the magnetic attraction device, so that the locking portion 13 and the mating portion 22 are aligned, and the possibility of dislocation and dropping can be reduced. It can be understood that the depth of the locking hole is shallow. By providing a magnetic attraction device with adsorption force on the mating portion 22, when an authorized person holds the disassembly tool 20 and aligns it with the screw assembly 10, the accurate positioning of the disassembly tool 20 and the screw assembly 10 can be achieved through the adsorption force of the magnetic attraction device, improving the disassembly efficiency. In this embodiment, the magnetic attraction device can be a magnetic ring. The magnetic ring is arranged at the end of the mating portion 22. When the mating portion 22 approaches the locking portion 13, the magnetic ring makes the mating portion 22 and the locking portion 13 fit together under the action of the adsorption force, effectively reducing the possibility of dislocation or dropping.

[0061] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
