Each connecting portion 32 may include a guiding groove 321 extending along the moving direction D1.

[0069] The locking bolt 40 is movably disposed in the fixing member 30. The locking bolt 40 includes a central portion 41, a plurality of elastic arms 42, and a plurality of hook portions 43. The central portion 41 may be a hollow structure. The central portion 41 may extend along the moving direction D1 and correspond to the first through hole 11. The elastic arms 42 are connected to the central portion 41, and the hook portions 43 are connected to the ends of the elastic arms 42. In this embodiment, the locking bolt 40 has two elastic arms 42, and the central portion 41 is located between the plurality of elastic arms 42.

[0070] In the locked state, the central portion 41 is located within the fixing portion 31. The elastic arm 42 is movably in contact with the connecting portion 32. In this embodiment, the elastic arm 42 of the locking bolt 40 is movably disposed within the guiding groove 321, and the guiding groove 321 restricts the movement of the locking bolt 40 along the moving direction D1. In addition, the engaging portion 43 is engaged with the top of the connecting portion 32 of the fixing member 30, and the fixing portion 31 is located between a plurality of engaging portions 43. Therefore, the engaging portion 43 can be used to prevent the locking bolt 40 from detaching from the fixing member 30.

[0071] The elastic component 50 is disposed between the fixing member 30 and the locking bolt 40. In this embodiment, the elastic component 50 can be a spring. In the locked state, the elastic component 50 is located within the fixing portion 31 and the central portion 41, and both ends of the elastic component 50 respectively abut against the fixing portion 31 and the central portion 41. The elastic component 50 provides an elastic force to the fixing portion 31 and the central portion 41 to maintain the locking bolt 40 at a locked position.

[0072] The locking pin 60 is movably located within the first through hole 11 and the second through hole 21. The locking pin 60 includes a body portion 61, a plurality of locking buckles 62, and a base portion 63. The body portion 61 can be a hollow structure and extends along the moving direction D1. The body portion 61 has a plurality of locking grooves 611. The locking grooves 611 are separated from the locking buckles 62. The locking buckles 62 and the base portion 63 are connected to the body portion 61, and the body portion 61 is located between the locking buckles 62 and the base portion 63. The second plate member 20 further includes a limiting groove 23 communicating with the second through hole 21. In this embodiment, the limiting groove 23 surrounds the second through hole 21.

[0073] In this embodiment, the width of the body portion 61 is adapted to the widths of the first through hole 11 and the second through hole 21. The width of the locking buckle 62 is adapted to the widths of the first limiting groove 12 and the second limiting groove 22. The width of the base portion 63 is adapted to the width of the limiting groove 23. The width of the base portion 63 is greater than the width of the body portion 61, and the width of the limiting groove 23 is greater than the widths of the first through hole 11 and the second through hole 21. The above widths are measured in the same direction perpendicular to the moving direction D1.

[0074] In this embodiment, when in a locked state, the locking pin 60 is fastened to the first plate member 10 and the second plate member 20. At this time, the main body portion 61 is located within the first through hole 11 and the second through hole 21. The buckle 62 is fastened to the edge of the first through hole 11 of the first plate member 10. The base portion 63 is located within the limiting groove 23 and abuts against the bottom of the limiting groove 23. In addition, the elastic force of the elastic component 50 maintains the elastic arm 42 of the locking bolt 40 within the locking groove 611, thereby preventing the locking pin 60 from rotating relative to the first plate member 10, the second plate member 20, and the locking bolt 40. Therefore, the anti-disassembly device 1 of this embodiment can well couple the second plate member 20 to the first plate member 10.

[0075] In one embodiment, the first plate member 10 is a part of the outer housing of an electronic device, and the second plate member 20 is a part of the cover of the electronic device. The fixing member 30, the locking bolt 40, and the elastic component 50 are located inside the outer housing of the electronic device, and the locking pin 60 is exposed on the outer surface of the cover of the electronic device. When the anti-disassembly device 1 is in the locked state, since the fixing member 30 and the locking bolt 40 restrict the movement and rotation of the locking pin 60 relative to the second plate member 20, it is difficult for the user to remove the locking pin 60 from the second plate member 20 from the outside of the electronic device without damaging the second plate member 20 or the locking pin 60, thereby achieving the purpose of anti-disassembly.

[0076] In this embodiment, the base portion 63 of the locking pin 60 includes a rotation groove 631 and an unlocking hole 632. The rotation groove 631 can extend perpendicular to the moving direction D1, and the unlocking hole 632 can extend along the moving direction D1. The cross-sectional area of the unlocking hole 632 is smaller than the cross-sectional area of the rotation groove 631. The cross-section of the unlocking hole 632 and the cross-section of the rotation groove 631 are respectively perpendicular to the moving direction D1. The locking pin 60 further includes an anti-disassembly wall 64 located between the rotation groove 631 and the unlocking hole 632 for separating the rotation groove 631 and the unlocking hole 632. In other words, the anti-disassembly wall 64 covers the unlocking hole 632. In this embodiment, the main body portion 61, the buckle 62, the base portion 63, and the anti-disassembly wall 64 of the locking pin 60 can be made of a plastic material and can be an integrally formed structure.

[0077] As Figure 5 shown, the tool T1 includes a handle T11, a first rotating block T12, a second rotating block T13, and a push rod T14. The first rotating block T12 and the second rotating block T13 are respectively located at both ends of the handle T11. The sizes of the first rotating block T12 and the second rotating block T13 match the size of the rotation groove 631 of the locking pin 60. The push rod T14 is connected to the second rotating block T13.

[0078] Figure 6 and Figure 7 is a cross-sectional view of the anti-disassembly device 1 according to the first embodiment of the present invention during a locking process. AsFigure 6 As shown, when the second plate member 20 is to be fixed to the first plate member 10, the second plate member 20 can be brought into contact with the first plate member 10. Then, the first rotating block T12 of the tool T1 is inserted into the rotating groove 631, and the locking pin 60 is pushed along the moving direction D1. At this time, the locking pin 60 sequentially passes through the second plate member 20 and the first plate member 10 along the moving direction D1, and the central portion 41 of the body portion 61 of the locking pin 60 pushes the locking bolt 40 to move along the moving direction D1. In addition, the buckle 62 moves to the installation position after passing through the second limiting groove 22 of the second plate member 20 and the first limiting groove 12 of the first plate member 10. In the installation position shown in FIG. 6, the buckle 62 is adjacent to the opening of the first limiting groove 12, the body portion 61 abuts against the elastic arm 42 of the locking bolt 40, the base portion 63 is located in the limiting groove 23, and the central portion 41 of the locking bolt 40 is located in the fixing portion 31 of the fixing member 30.

[0079] When the user rotates the tool T1 to rotate the locking pin 60, as Figure 1 and Figure 7 shown, the anti-disassembly device 1 is in a locked state. In this embodiment, the first rotating block T12 of the tool T1 is inserted into the rotating groove 631, and the user can use the tool T1 to rotate the locking pin 60 by 90 degrees. The buckle 62 is latched to the first plate member 10, and the base portion 63 is located in the limiting groove 23. In addition, by the elastic force of the elastic component 50, the locking bolt 40 is pushed along the moving direction D1 so that the elastic arm 42 of the locking bolt 40 is located in Figure 6 the locking groove 611 of the locking pin 60. In the locked state, the fixing member 30 and the locking bolt 40 restrict the movement and rotation of the locking pin 60 relative to the second plate member 20, so that the anti-disassembly device 1 can fix the second plate member 20 to the first plate member 10.

[0080] Figure 8 and Figure 9 are cross-sectional views of the anti-disassembly device 1 according to the first embodiment of the present invention during a disassembly process. As Figure 7 and Figure 8 shown, when the user wants to separate the second plate member 20 from the first plate member 10, the user can use the ejector rod T14 of the tool T1 to pierce the anti-disassembly wall 64 through the rotating groove 631 and then pass through the unlocking hole 632. Then, the ejector rod T14 continues to move along the moving direction D1 to push the central portion 41 of the locking bolt 40 out of the locking groove 611 of the locking pin 60. At this time, the locking bolt 40 allows the locking pin 60 to rotate relative to the first plate member 10. In addition, the second rotating block T13 of the tool T1 can be located in the rotating groove 631.

[0081] After the user rotates the tool T1 to rotate the locking pin 60 to an unlocking position, the buckle 62 corresponds to the first limiting groove 12 and the second limiting groove 22, and the locking pin 60 allows the first plate member 10 and the second plate member 20 to be separated. In this embodiment, the second rotating block T13 of the tool T1 is inserted into the rotating groove 631, and the user can use the tool T1 to rotate the locking pin 60 by 90 degrees. As Figure 9 shown, the anti-disassembly device 1 is in an unlocked state. At this time, the user can detach the locking pin 60 from the first plate member 10 and the second plate member 20 along the moving direction D1, and the buckle 62 sequentially passes through the first limiting groove 12 and the second limiting groove 22. Since the locking pin 60 is detached from the first through hole 11 and / or the second through hole 21, the second plate member 20 can be separated from the first plate member 10.

[0082] Figure 10 The explosion diagram of the anti-disassembly device 1 according to the second embodiment of the present invention. The anti-disassembly device 1 further includes a third plate member 70. The third plate member 70 can extend perpendicular to the moving direction D1, but is not limited thereto. For example, the third plate member 70 can have an arc-shaped curved surface. The third plate member 70 includes a first opening 71 and one or more second openings 72. The second plate member 20 and the third plate member 70 can be part of the housing and / or cover of the electronic device, but are not limited thereto.

[0083] The first plate member 10 further includes one or more fixing blocks 13. One or more locking components T2 can pass through the second openings 72 of the third plate member 70 and be locked to the fixing blocks 13 of the first plate member 10, so as to fix the third plate member 70 to the first plate member 10. In addition, the second plate member 20 further includes a convex block 24, and the second through hole 21 and the second limiting groove 22 can extend to the convex block 24. When the second plate member 20 is attached to the third plate member 70, the convex block 24 is located in the first opening 71 of the third plate member 70.

[0084] In summary, the anti-disassembly device of the present invention needs to be removed by a specific tool, which can prevent users from easily disassembling the shell of electronic products by themselves. In addition, when the user unlocks the anti-disassembly device with a tool, it is necessary to damage the anti-disassembly wall of the locking pin, and it is difficult for the user to restore it. Moreover, the locking pin is of a specific specification and is not a conventional component, so it is difficult to purchase and replace. Therefore, the manufacturer can judge whether the electronic product has been disassembled by the user by observing whether the anti-disassembly wall is damaged, and thus can provide the basis for the manufacturer to identify the liability for damage of the electronic product.

[0085] For those of ordinary skill in the art, other corresponding changes or adjustments can be made according to the actual needs generated by combining the creative solutions and creative concepts of the present invention, and these changes and adjustments should fall within the protection scope of the claims of the present invention.
