Anti-disassembly device
View Patent ↗An anti-disassembly device includes a first part including a first through hole; a fixing element affixed to the first part; a bolt movably disposed on the fixing element; an elastic element between the fixing element and the bolt; a second part in contact with the first part and having a second through hole; and a nail movably disposed in the first through hole and the second through hole. The nail has a lock groove. In a locked state, the nail is engaged with the first part and the second part, and the bolt is located in the lock groove and prevents the nail from rotating relative to the first part. When the nail is rotated to an unlocking position, the nail allows the first part to separate from the second part.
1 . An anti-disassembly device comprising:
a first part comprising a first through hole, and a first restriction groove connected to the first through hole;
a fixing element affixed to the first part;
a bolt movably disposed in the fixing element;
an elastic element between the fixing element and the bolt;
a second part in contact with the first part, and comprising a second through hole; and
a nail movably disposed in the first through hole and the second through hole, and the nail comprising a lock groove, a body in the first through hole, and a buckle connected to the body;
wherein when the anti-disassembly device is in a locked state, the nail is fastened to the first part and the second part, the buckle is fastened to the first part, and the bolt is in the lock groove to prevent the nail from rotating relative to the first part,
when the bolt is moved out of the lock groove, the nail is rotatable relative to the first part,
when the nail is rotated to an unlocking position, the first part is separatable from the second part, and the buckle corresponds to the first restriction groove, and
the buckle extends through the first restriction groove when the nail is away from the first part in a movement direction.
2 . The anti-disassembly device as claimed in claim 1 , wherein the fixing element comprises a guide groove, the bolt is movably disposed in the guide groove, and the guide groove restricts the bolt from moving in the movement direction.
3 . The anti-disassembly device as claimed in claim 1 , wherein the bolt comprises a central portion and an arm connected to the central portion,
wherein when the anti-disassembly device is in the locked state, the arm is in the lock groove.
4 . The anti-disassembly device as claimed in claim 3 , wherein the fixing element comprises a fixing portion and a connection portion connected to the fixing portion, the elastic element abuts the fixing portion and the central portion, and the arm is movably in contact with the connection portion.
5 . The anti-disassembly device as claimed in claim 4 , wherein each of the central portion and the fixing portion is a hollow structure, and the elastic element is disposed in the central portion and the fixing portion, and
when the anti-disassembly device is in the locked state, the central portion is in the fixing portion.
6 . The anti-disassembly device as claimed in claim 4 , wherein the bolt further comprises a hook connected to the arm, the hook preventing the bolt away from the fixing element.
7 . The anti-disassembly device as claimed in claim 1 , wherein the second part further comprises a second restriction groove connected to the second through hole, and
the body is in the second through hole when the anti-disassembly device is in the locked state, and the buckle extends through the second restriction groove when the nail is away from the second part in the movement direction.
8 . The anti-disassembly device as claimed in claim 7 , wherein an area of an opening of the first through hole is greater than an area of an opening of the first restriction groove, and an area of the second through hole is greater than an area of the second restriction groove.
9 . The anti-disassembly device as claimed in claim 7 , wherein a width of the buckle matches to a width of the first restriction groove and a width of the second restriction groove, and the width of the buckle, the width of the first restriction groove, and the width of the second restriction groove are measured in the same direction.
10 . The anti-disassembly device as claimed in claim 7 , wherein the nail further comprises a base connected to the body, and the second part further comprises a constraint slot connected to the second through hole,
a width of the base is greater than a width of the body, and the base is in the constraint slot when the anti-disassembly device in the locked state, and the width of the base and the width of the body are measured in the same direction.
11 . The anti-disassembly device as claimed in claim 10 , wherein the constraint slot surrounds the second through hole, and a width of the constraint slot is greater than a width of the first through hole and a width of the second through hole, and the width of the constraint, the width of the first through hole, and the width of the second through hole are measured in the same direction.
12 . The anti-disassembly device as claimed in claim 10 , wherein the width of the body matches respectively to a width of the first through hole and a width of the second through hole, the width of the base matches to a width of the constraint slot, and the width of the body, the width of the first through hole, and the width of the second through hole, the width of the base, and the width of the constraint slot are measured in the same direction.
13 . The anti-disassembly device as claimed in claim 1 , wherein the nail further comprises a unlock hole and an anti-demolition wall covering the unlock hole, and
the bolt is accessible to be pushed away from the lock groove by a tool when the tool pierces the anti-demolition wall to access the unlock hole.
14 . The anti-disassembly device as claimed in claim 13 , wherein the nail further comprises a rotation groove, the anti-demolition wall is between the rotation groove and the rotation groove, a cross-sectional area of the unlock hole is smaller than a cross-sectional area of the rotation groove, and the nail is rotatable by inserting a tool into the rotation groove, wherein the cross-sectional area of the unlock hole is parallel to the cross-sectional area of the rotation groove.
