Description

[0001] This application is a divisional application of the invention patent application entitled "Anti-theft Connection Device for Equipment", which entered the Chinese national phase on August 5, 2022, and has the national application number 202180013170.1. Technical Field

[0002] This invention relates to an anti-theft connection device for connecting a security wire to a security slot formed in a device such as a notebook computer, and more specifically, to an anti-theft connection device for devices capable of accommodating security slots with different opening widths. Background Technology

[0003] To protect small devices such as laptops, monitors, tablets, mobile phones, and smartphones from theft, some devices have security slots in their outer casings. These security slots house anti-theft connectors and secure cables. By attaching these secure cables to tables, pillars, display stands, or similar structures in a secure manner, these devices are prevented from being taken out or stolen.

[0004] For example, Patent Document 1 proposes an anti-theft connection device that is installed in a security slot of a device. The anti-theft connection device has a T-shaped anti-detachment plate at the front end and a rotation-stopping plate that can slide relative to the anti-detachment plate. The anti-detachment plate is inserted into the security slot, and the rotation-stopping plate is inserted while the anti-detachment plate is rotated 90°. The security wire is then inserted to prevent relative movement between them.

[0005] Existing technical documents Patent documents Patent document 1: Japanese Patent No. 3559501. Summary of the Invention

[0006] The problem that the invention aims to solve To ensure the anti-theft connector engages securely with the security slot without detaching, anti-detachment and anti-rotation plates need to be compatible with the slot's dimensions. However, security slots come in various sizes, such as 4.5mm×3.2mm (opening width × opening height), 6mm×2.5mm, and 7mm×3mm. Larger anti-theft connectors cannot be installed in smaller slots. Furthermore, installing smaller connectors in larger slots can lead to detachment. Therefore, there is a need to prepare multiple anti-theft connector options to suit different security slot dimensions.

[0007] Therefore, we are looking for anti-theft connection devices that can accommodate security slots of different sizes.

[0008] The purpose of this invention is to provide an anti-theft connection device that can be connected to a device with a security slot of a different size.

[0009] Methods used to solve problems The anti-theft connection device of the present invention is an anti-theft connection device installed in a security slot of a device, comprising: a housing having an insertion protrusion opening at a front end; a first insertion piece having a first insertion claw capable of engaging with the aforementioned security slot protruding from the insertion protrusion opening of the housing, the base end being a first base housed within the housing; a second insertion piece having a second insertion claw capable of engaging with the aforementioned security slot protruding from the insertion protrusion opening of the housing, the base end being a second base housed within the housing; and a support portion within the housing, pivotally supporting the first and second insertion pieces between the front end and the base end, for the first insertion piece... The first insert and the second insert are supported in a manner that allows for variable opening angles; an insert force-applying mechanism applies force within the housing to reduce the opening angles of the first insert and the second insert; an angle adjustment mechanism, located within the housing and inserted between the first base and the second base, is capable of adjusting the relative opening angles of the first insert and the second insert by at least a first opening angle and a second opening angle; and a locking mechanism, which holds and locks the angle adjustment mechanism in a state where the angle adjustment mechanism has adjusted the first insert and the second insert to the first opening angle or the second opening angle.

[0010] The aforementioned angle adjustment mechanism includes an angle adjustment piece, which is applied force toward the base end of the aforementioned housing and can penetrate between the aforementioned first base and the aforementioned second base at its front end; the aforementioned angle adjustment mechanism can be moved to a first position where the aforementioned angle adjustment piece penetrates between the aforementioned first base and the aforementioned second base, thereby making the aforementioned first insert piece and the aforementioned second insert piece the aforementioned first opening angle; a second position where the aforementioned angle adjustment piece penetrates between the aforementioned first base and the aforementioned second base, thereby making the aforementioned first insert piece and the aforementioned second insert piece the aforementioned second opening angle; and a third position where the aforementioned angle adjustment piece does not penetrate between the aforementioned first base and the aforementioned second base.

[0011] It can be structured as follows: it includes an adjuster component that moves the aforementioned angle adjustment mechanism between the aforementioned first position and the aforementioned third position, and between the aforementioned second position and the aforementioned third position.

[0012] It is possible to make the aforementioned adjuster component, when locked by the aforementioned locking mechanism, push the aforementioned angle adjustment mechanism from the aforementioned third position to the aforementioned first position or from the aforementioned third position to the aforementioned second position.

[0013] The aforementioned angle adjustment mechanism has a recess and a protrusion on the base end side; the aforementioned adjuster component can push the aforementioned angle adjustment mechanism from the aforementioned third position to the aforementioned first position by abutting against the aforementioned protrusion, and can push the aforementioned angle adjustment mechanism from the aforementioned third position to the aforementioned second position by abutting against the aforementioned recess.

[0014] The aforementioned angle adjustment mechanism and the aforementioned adjuster component are screwed together. By rotating the aforementioned adjuster component relative to the aforementioned angle adjustment mechanism, the length of the aforementioned angle adjustment mechanism and the aforementioned adjuster component can be adjusted.

[0015] The aforementioned locking mechanism includes a locking pin, which is disposed on the base end side of the aforementioned housing and is movably disposed toward the base end side. The aforementioned locking mechanism is locked by moving the aforementioned locking pin toward the base end side of the aforementioned housing. When the aforementioned locking pin moves toward the base end side of the aforementioned housing, the front end of the aforementioned locking pin pushes the aforementioned angle adjustment mechanism toward the front end side of the aforementioned housing.

[0016] Preferably, it has a wire component that connects to the aforementioned housing.

[0017] Invention Effects According to the anti-theft connection device of the device of the present invention, by pre-setting the opening angle of the insert piece to match the size of the security slot, the insert piece can be locked and held at the opening angle, so that even if the size (opening width) of the security slot is different, it can be engaged with the security slot to lock.

[0051] <Basic Structure> Regarding the anti-theft connection device 10 (security lock) of the present invention, as follows: Figure 1 (a) to Figure 1As shown in (c), the device has insert tabs 20, 20 (one corresponding to a first insert tab and the other to a second insert tab), each insert tab 20, 20 having insert claws 21, 21 capable of being inserted into and engaged with a security slot 90 or 91 formed in a device such as a laptop computer. The insert tabs 20, 20 are supported by a support shaft 28, and the insert claws 21, 21 at their front ends (one corresponding to a first insert claw and the other to a second insert claw) are bent in opposite directions. The insert tabs 20, 20 can adjust their opening angle to match the opening width of the security slot 90 or 91 and are locked in place at a predetermined opening angle.

[0052] Safety slots can be exemplified by opening widths of 4.5mm, 6mm, and 7mm. However, since the 6mm and 7mm opening widths can be shared by the insert pieces 20, 20 with the same opening angle, in the first embodiment, a safety slot 90 with an opening width of 4.5mm is used (see reference). Figure 1 (b) and other opening widths (6mm and 7mm) of the safety slot 91 (refer to) Figure 1 (c) The two-stage adjustable anti-theft connection device 10 is used as an example for explanation. Regarding the opening angle of the inserts 20, 20, the first opening angle that engages with the security slot 90 with an opening width of 4.5mm is set as θ1 ( Figure 1 (b) The second opening angle for engaging with the safety slot 91 (6mm and 7mm) is set to θ2. Figure 1 (c) Let θ1 < θ2. Of course, it can also be configured as a 3-level adjustment, as shown in other embodiments, or corresponding to different opening widths.

[0053] Insert pieces 20, 20 as Figure 1 As shown, the bases 22, 22 (one corresponding to the first base and the other to the second base) are equipped with annular rubber, springs, and other insert force-applying mechanisms 25, which apply force in the closing direction of the insert claws 21, 21. The opening angle of the inserts 20, 20 is adjusted as follows: Figure 1 As shown, this is achieved by the angle adjustment mechanism 30. The angle adjustment mechanism 30 can be configured with an angle adjustment piece 31 in the shape of a shaft at its front end. For example, by adjusting the depth to which the angle adjustment piece 31 penetrates between the bases 22, 22 of the insertion pieces 20, 20, the opening angle of the insertion pieces 20, 20 can be adjusted. Specifically, by shallowly penetrating the angle adjustment piece 31 between the bases 22, 22, the opening angle of the insertion pieces 20, 20 can be adjusted as follows: Figure 1 As shown in (b), the insert pieces 20, 20 are positioned at the first opening angle θ1, and the angle adjustment piece 31 penetrates deeper into the space between the bases 22, 22, so as... Figure 1 (c) Adjust the insert pieces 20, 20 to a second opening angle θ2 that is larger than the first opening angle θ1.

[0054] On the other hand, if the angle adjustment mechanism 30, i.e., the angle adjustment piece 31, is pulled out from between the bases 22, 22 of the insert pieces 20, 20, then by means of the force applied by the insert piece force application mechanism 25, such as Figure 1 As shown in (a), the insertion claws 21 and 21 close, becoming narrower than the width of the safety slots 90 and 91, and can be inserted and removed relative to the safety slots 90 or 91.

[0055] Hereinafter, Embodiments 1 to 4 will be described with reference to the accompanying drawings. Furthermore, common reference numerals, names, etc., used in the above description and the following embodiments will be appropriately omitted.

[0056] <First Embodiment> Figures 2 to 11 This refers to an anti-theft connection device 10 according to one embodiment of the present invention. Figure 2 This is a perspective view of the anti-theft connection device 10 from a diagonal front, showing the insertion claws 21 and 21 in the closed position. Figure 3 This is the state where the insertion claws 21 and 21 are open. Figure 4 This is a three-dimensional view of the anti-theft connection device 10 viewed from a diagonal rear angle. Figure 5 This is a 3D view of the unlocked state of the locking mechanism 40. Figure 6 This is a 3D view of the locked state of the locking mechanism 40. Figure 7 This indicates that key 80 or 84 is inserted into the locking mechanism 40. Furthermore, Figure 8 , Figure 9 This is an exploded 3D view of the anti-theft connection device 10. Figure 10 This indicates that the insertion claws 21, 21 are locked and held at the first opening angle. Figure 11 This indicates that the insertion claws 21, 21 are locked and held at the second opening angle. Additionally, the first opening angle is set to be larger than the second opening angle.

[0057] Hereinafter, the direction in which the insertion claws 21, 21 extend is referred to as the front end side, and the direction in which the locking pin 41 extends is referred to as the base end side.

[0058] like Figures 2 to 7 As shown, when viewed visually, the anti-theft connection device 10 has a pair of insertion claws 21, 21 extending from the front end of the housing 70, and a wire connection portion 71 for connecting the wire component (security wire) is located on the body of the housing 70. The base end of the housing 70 is sealed by a rear cover 60, and a locking pin 41 extends from the center of the rear cover 60. In the illustrated embodiment, as also referred to... Figure 8 and Figure 9 As can be seen, the housing 70 is cylindrical and is held at the front end by an insert retainer 26 (in Figure 2 , Figure 3A resin buffer material 29 is installed at the front end of the insert holder 26 to seal it, and an insert protrusion 27 with insert claws 21 extending out is formed in the insert holder 26. In addition, a locking mechanism 40 is provided inside the rear cover 60 on the base side.

[0059] exist Figure 8 and Figure 9 The diagram shows the internal structure of the anti-theft connection device 10. Inside the cylindrical housing 70, the insert holder 26 can be positioned at the front end using a C-ring 26A. The insert holder 26 is hollow inside, open at the base, and closed at the front end. A through hole 28a is provided in the body of the insert holder 26, and a support shaft 28 (support part) for supporting the inserts 20 is installed thereon.

[0060] In the insert holder 26, a pair of insert pieces 20, 20 are pivotally supported by a support shaft 28. The insert pieces 20, 20 are as follows... Figure 10 and Figure 11 As shown, the insert claws 21, 21 protrude in opposite directions and can engage with the safety slots 90 or 91 formed in the device. The insert tabs 20, 20 cross within the insert tab holder 26, and the support shaft 28 passes through the support holes 24, 24 formed at the crossing position. Recesses 23 are formed on the outer surfaces of the bases 22, 22, respectively, and the insert tab force application mechanism 25, which is annular rubber, is hooked onto these recesses 23, 23 (see also...). Figure 1 ), and apply force in the direction that brings the bases 22, 22 closer to each other, that is, in the direction that reduces the opening angle of the insertion claws 21, 21.

[0061] Inside the housing 70, a helical spring is clamped in the angle adjustment mechanism force application mechanism 34. The front end of the angle adjustment mechanism force application mechanism 34 abuts against the insert holder 26, and the base end abuts against the angle adjustment mechanism 30, so that the angle adjustment mechanism 30 always applies force to the base end.

[0062] The angle adjustment mechanism 30 is a component that limits the opening angle of the aforementioned insert pieces 20, 20 during locking. The angle adjustment mechanism 30, for example, includes a shaft-shaped angle adjustment piece 31. The angle adjustment piece 31 is as described in the basic structure above. Figure 1 As explained in the text, the opening angle of the insert pieces 20 and 20 can be adjusted by changing the penetration depth between the bases 22 and 22.

[0063] By making the angle adjustment piece 31 as Figure 10 ( Figure 1As shown in (b), the insertion pieces 20, 20 are shallowly inserted between the bases 22, 22, so that the opening angle of the insertion pieces 20, 20 is a first opening angle θ1 that matches the opening width of the safety slot 90 of 4.5 mm. Furthermore, the angle adjustment piece 31 can be adjusted as shown in (b). Figure 11 ( Figure 1 (c) The inserts penetrate deeper into the bases 22, 22 of the insert pieces 20, 20 as shown, so that the opening angle of the insert pieces 20, 20 becomes a second opening angle θ2 that matches the opening width of the safety slot 91, which is 6 mm or 7 mm. If the angle adjustment piece 31 is retracted from the bases 22, 22 of the insert pieces 20, 20, the insert pieces 20, 20 are forced together in the closing direction by the insert force application mechanism 25, such as... Figure 2 , Figure 1 (a) and so on, become closed.

[0064] On the base end face of the angle adjustment mechanism 30, such as Figures 9 to 11 As shown, a semi-circular rib 36 is formed. The rib 36 is a component in which a recess 36a and a protrusion 36b are formed on the base end face of the angle adjustment mechanism 30. The portion without the rib 36 is the recess 36a, relative to the protrusion 36b on which the rib 36 is formed. The adjuster component 45, described below, abuts against this recess 36a and protrusion 36b, causing the angle adjustment mechanism 30 to reach the locked position. Figure 10 ( Figure 1 (b)) shows the first position, Figure 11 ( Figure 1 (c)) In the unlocked state, at one of the second positions shown, the angle adjustment mechanism 30 moves to the third position retracted from the insert pieces 20, 20. Figure 1 (a)).

[0065] The adjuster component 45 is provided with a locking pin 41 on the base end side of the angle adjustment mechanism 30. The locking pin 41 is axially slidable within the housing 70 and rotatable about an axis. Specifically, a sliding groove 43 extending axially is provided through the locking pin 41, and the sliding shaft 57 of the second rotor 55 (described later) is fitted into it. Thus, the locking pin 41 can slide relative to the second rotor 55, and also can rotate together with the second rotor 55 within the housing 70.

[0066] Two locking grooves 44, 44 are formed on the locking pin 41 at 180° offset positions on its circumference. Furthermore, when the locking mechanism 40 is pushed into the front end of the housing 70, the return limiting shaft 52 of the first rotor enters the locking groove 44, locking the locking pin 41 in place. If the locking pin 41 is rotated from this state, the return limiting shaft 52 disengages from the locking groove 44, releasing the lock on the locking pin 41. Since the locking pin 41 is forced towards its base by a locking pin force-applying mechanism 42, such as a helical spring located at the front end, the locking pin 41 retracts if the lock is released.

[0067] The adjuster component 45 provided on the locking pin 41 can be made into a shaft component orthogonal to the axial direction at the front end side of the locking pin 41 (see reference). Figure 10 and Figure 11 It rotates and slides within the housing 70 together with the locking pin 41. Furthermore, as... Figure 10 As shown, if the locking pin 41 is pushed towards the front end while the adjuster component 45 is facing the recess 36a of the angle adjustment mechanism 30, the locking position of the angle adjustment mechanism 30 will be moved to the front end. Figure 10 The first position is shown. Furthermore, the adjuster component 45 rotates the locking pin 41 180° together with the second rotor 55 (described later), as shown... Figure 11 As shown, when moved to the position opposite to the protrusion 36b of the angle adjustment mechanism 30, the locking pin 41 can be pushed in from this state to make the locking position of the angle adjustment mechanism 30 the second position. Moreover, the locking pin 41 is released from the locking mechanism 40 from any position and is retracted to the base end side by means of the locking pin force application mechanism 42.

[0068] The sliding and rotation of the locking pin 41 are restricted by the locking mechanism 40, which will be described next.

[0069] The locking mechanism 40 can be exemplified as a tubular pin tumbler lock. The tubular pin tumbler lock can employ a known structure, so detailed descriptions of its construction and operation are omitted, but it includes a first rotor 50 located at the front end within the housing 70 and a second rotor 55 at the base end. The first rotor 50 is immobilized relative to the rear cover 60 and the housing 70 by means of a retaining pin 51, while the second rotor 55 is rotatable relative to the first rotor 50 in the unlocked state and immobile relative to the first rotor 50 in the locked state.

[0070] The rotation of the first rotor 50 and the second rotor 55 is controlled by the code pins 56 housed within them. Figure 10 and Figure 11 , Figures 12 to 14 The diagram illustrates the locking pins of the second rotor 55. The second rotor 55 has a retaining groove 58 recessed at its base end. In the second rotor 55, as... Figures 11 to 15 As shown, a locking groove 58 is recessed on the inner circumferential surface, which allows the keys 80 and 84 to be inserted or removed when aligned with a certain hole 61 or 62 formed on the base end face of the rear cover 60.

[0071] In this embodiment, two holes 61 and 62 are formed at a 180° offset position. One hole 62 is designated as reference numeral "1" and "2", and the other hole 61 is designated as reference numeral "3". Furthermore, the opening angles of the insertion claws 21 and 21 are set to a first opening angle θ1 and a second opening angle θ2, respectively, depending on which hole 61 or 62 the locking groove 58 of the second rotor 55 is opposite to. Additionally, in this embodiment, as... Figure 10 As shown, by aligning the locking groove 58 with the gap 61 marked with reference numeral "3", the first opening angle θ1 is set; as Figure 11 As shown, the second opening angle θ2 is set by aligning the locking groove 58 with the gap 62 marked with reference numerals "1" and "2".

[0072] In this embodiment, the key used to lock and unlock the locking mechanism 40 can be a... Figure 15 (a) The adjusting key 80 for adjusting the opening angle of the adjusting inserts 20, 20, and Figure 15 (b) shows the key 84 used for normal locking and unlocking. Each key 80 and 84 has locking tabs 81 and 85, which are inserted into the locking groove 58 of the rear cover 60 after being aligned with the locking groove 58 of the locking mechanism 40. When the key 80 or 84 is inserted into the second rotor 55, the key groove 82 formed in the key 80 or 84 adjusts the height of the locking pin 56. By aligning the heights of the locking pins 56, the second rotor 55 can rotate relative to the first rotor 50. Conversely, the key 80 or 84 can be pulled out by aligning the locking groove 58 with the hole 61 or 62. When the key 80 or 84 is pulled out, the locking pin on the first rotor 50 side penetrates into the second rotor 55, restricting the rotation of the second rotor 55.

[0073] In this embodiment, such as Figures 10 to 14 , Figure 16 and Figure 17 As shown, the rear cover 60 has a stepped groove 63 formed on a portion of its inner surface opposite to the second rotor 55. In this embodiment, two stepped grooves 63 are formed. Specifically, the stepped groove 63 extends from... Figure 12 , Figure 13 The aperture 61, marked with reference numeral "3" in the attached diagram, is formed at approximately 90° clockwise. Furthermore, as... Figure 14 As shown, it is formed approximately 90° clockwise from the aperture 62 marked with reference numerals "1" and "2". Figure 16As shown in (a), the adjuster key 80 is designed to be of a length such that the locking piece 81 is not exposed from the locking groove 58 when the adjuster key 80 is inserted into the second rotor 55. Therefore, the adjuster key 80 can rotate the second rotor 55 by at least 180°. On the other hand, as... Figure 15 , Figure 16 As shown in (b), the locking piece 85 of the opening / closing key 84 is formed to be longer than the locking piece 81 of the adjuster key 80. Specifically, the locking piece 85 is the length by which its base extends into the stepped groove 63. That is, when the opening / closing key 84 is inserted into the second rotor 55, since the locking piece 85 protrudes from the locking groove 58 toward the stepped groove 63 side, the opening / closing key 84 can rotate within a range of approximately 90° in which the stepped groove 63 is formed, but further rotation is restricted.

[0074] Therefore, in such Figure 16 When the adjuster key 80 is inserted into the locking mechanism 40 as shown in (a), the locking piece 81 is fully accommodated in the locking groove 58 of the second rotor 55, allowing the second rotor 55 to rotate freely. Thus, by means of the adjuster key 80, for example, from the position of the slot 61 marked "3" to the position of the slot 62 marked "1" and "2", or from the position of the slot 62 marked "1" and "2" to the position of the slot 61 marked "3", the second rotor 55 can be rotated. Therefore, the adjuster key 80 can not only unlock and release the locking mechanism 40, but also rotate the locking pin 41 on which the adjuster component 45 is located by 180°.

[0075] On the other hand, such as Figure 16 As shown in (b), the opening and closing key 84 is restricted in its rotation angle because the locking piece 85 extends to the side of the stepped groove 63. The opening and closing key 84 can unlock the locking mechanism 40, but cannot rotate the locking pin 41 180°.

[0076] The anti-theft connection device 10 with the above structure can be used under the following conditions.

[0077] When using the anti-theft connection device 10 on the security slot 90 with an opening width of 4.5mm, Figure 15 (a) The adjuster key 80 shown is inserted into the locking mechanism 40 and rotated. The adjuster key 80, as described above, is... Figure 16 As shown in (a), the length of the locking piece 81 not protruding from the locking groove 58 allows the second rotor 55 to rotate freely. Then, as... Figure 10As shown, align the locking groove 58 of the second rotor 55 with the slot 61 marked with reference numeral "3", and pull out the adjuster key 80. This aligns the locking groove 58 of the second rotor 55 with the slot 61 marked with reference numeral "3". Consequently, the locking pin 41 and the adjuster component 45 rotate together with the second rotor 55, and the adjuster component 45 moves to a position where... Figure 9 The angle adjustment mechanism 30 shown is positioned opposite the recess 36a.

[0078] Insert pieces 20, 20 as Figure 1 As shown in (a), the insertion claws 21, 21 are maintained in the state where they are closed by the insertion plate force application mechanism 25. From this state, the insertion claws 21, 21 are inserted into the safety slot 90, and the locking pin 41 is pushed in. Thus, the adjuster component 45... Figure 10 The angle adjustment mechanism 30 is pushed as shown, but because the adjuster component 45 is opposite to the recess 36a of the angle adjustment mechanism 30, the pushing amount of the adjuster component 45 is small. Therefore, pushed by the adjuster component 45, the angle adjustment piece 31 penetrates shallowly into the bases 22, 22 of the insert pieces 20, 20. Thus, the insert pieces 20, 20 are matched with the width of the safety slot 90 and open to the first opening angle θ1 (refer to...). Figure 1 (b) Insertion claws 21, 21 engage with the security slot 90. The locking pin 41, due to the force applied by the force-applying mechanism 53, is forced into the locking groove 44 by the return limiting shaft 52, thus preventing retraction and locking the insertion claws 21, 21. Therefore, the anti-theft connection device 10 is connected to the security slot 90 of the device. By pre-connecting the (not shown) wiring component of the anti-theft connection device 10 to a table, pillar, etc., and then connecting the device to the table, etc., via the anti-theft connection device 10 and the wiring component, theft prevention can be achieved.

[0079] To remove the anti-theft connector 10 from the security slot 90, insert the opening / closing key 84 (or adjuster key 80) into the locking mechanism 40, causing the second rotor 55 to rotate approximately 90°, thus releasing the lock. This causes the locking pin 41 to rotate, the return limiting shaft 52 to disengage from the locking groove 44, and the locking pin force application mechanism 42 to retract the locking pin 41 towards the base end. Consequently, by the retraction of the locking pin 41, the angle adjustment mechanism 30 is moved towards the base end by the angle adjustment mechanism force application mechanism 34, and the angle adjustment piece 31 disengages from the bases 22, 22 of the insert pieces 20, 20. Since the insert pieces 20, 20 are forced in the closing direction by the insert piece force application mechanism 25, the insert pieces 20, 20 close by the disengagement of the angle adjustment piece 31 (see also...). Figure 1 (a) allows the insert pieces 20, 20 to be pulled out from the safety slot 90.

[0080] On the other hand, when using the anti-theft connection device 10 on the security slot 91 with an opening width of 6mm or 7mm, it is necessary to adjust the opening angle of the insertion claws 21, 21 to a second opening angle θ2. In this case, the adjuster key 80 is inserted into the locking mechanism 40 and rotated to align the locking groove 58 of the second rotor 55 with the slots 62 marked with reference numerals "1" and "2". By aligning the locking groove 58 of the second rotor 55 with the slots 62 marked with reference numerals "1" and "2", the locking pin 41 and the adjuster component 45 rotate together with the second rotor 55, and the adjuster component 45 moves to the position of the second rotor 55. Figure 11 The position of the protrusion 36b of the angle adjustment mechanism 30 shown.

[0081] Insert pieces 20, 20 as Figure 1 As shown, the insertion claws 21, 21 are maintained in the closed state by the insertion plate force application mechanism 25. From this state, the insertion claws 21, 21 are inserted into the safety slot 91, and the locking pin 41 is pushed in. Thus, the adjuster component 45... Figure 11 As shown, the angle adjustment mechanism 30 is pushed forward, but because the adjuster component 45 is opposite to the protrusion 36b of the angle adjustment mechanism 30, the pushing amount of the adjuster component 45 is greater than that in the case where it is opposite to the concave portion 36a. Therefore, pushed forward by the adjuster component 45, the angle adjustment piece 31 penetrates deeper into the bases 22, 22 of the insert pieces 20, 20. Thus, the insert pieces 20, 20 open to the second opening angle θ2 (also refer to...) by matching the width of the safety slot 91. Figure 1 (c) Insertion claws 21, 21 engage with the security slot 91. Locking pin 41 is prevented from retracting because the return limiting shaft 52 has entered the locking groove 44, thus locking and retaining insertion claws 21, 21. Therefore, the anti-theft connection device 10 is connected to the security slot 91 of the device, enabling anti-theft protection.

[0082] To remove the anti-theft connector 10 from the security slot 91, simply insert the opening / closing key 84 (or adjuster key 80) into the locking mechanism 40, causing the second rotor 55 to rotate approximately 90° and thus releasing the lock. Consequently, as described above, the locking pin 41 retracts, and the insert plates 20, 20 close (see...). Figure 1 (a) allows the insert pieces 20, 20 to be pulled out from the safety slot 91.

[0083] According to the present invention, the opening angle of the insert pieces 20, 20 can be adjusted to match the opening width of the security slot by means of the adjuster key 80, so it is not necessary to prepare the anti-theft connection device to match the opening width of the security slot. In addition, as long as the opening angle is temporarily adjusted by the adjuster key 80, the opening and closing key 84 can be used only for locking and unlocking. Therefore, by giving the opening and closing key 84 to users who are not used to using the anti-theft connection device 10 in advance, it is also possible to prevent the anti-theft connection device from being used at an opening angle that does not match the opening width.

[0084] In addition, in the above embodiment, the locking mechanism 40 is a tubular pin lock, but it can also be a cylinder lock, a dial lock, etc. Furthermore, the locking pin 41 and the adjuster component 45 can also be positioned using wire components, purse locks, etc.

[0085] Furthermore, the shape of the shell 70 is not limited to a cylindrical shape; it can also be a cuboid shape, etc.

[0086] <Second Embodiment> In the first embodiment, an adjuster component 45 is provided on the locking pin 41. By changing the orientation of the adjuster component 45, the insertion depth of the angle adjustment piece 31 is changed, thereby adjusting the opening angle of the insertion pieces 20, 20. In the second embodiment, as... Figures 17 to 21 As shown, the adjuster component 45 is screwed relative to the angle adjustment mechanism 30, so that the adjuster component 45 rotates relative to the angle adjustment mechanism 30.

[0087] Furthermore, in the anti-theft connection device 10 of the second embodiment, by changing the relative position of the angle adjustment mechanism 30 with respect to the adjuster component 45, the length of the angle adjustment mechanism 30 and the adjuster component 45 can be adjusted, and the penetration depth of the angle adjustment piece 31 can be adjusted when the locking pin 41 is pushed in.

[0088] Angle adjustment mechanism 30 Figure 17 and Figure 18 As shown, the guide portions 32, 32 protrude from the axial angle adjustment piece 31, and the guide portions 32, 32 are slidably embedded into the guide groove 72 within the housing 70 (see reference). Figure 17 The angle adjustment piece 31 can move parallel in the axial direction within the housing 70.

[0089] Furthermore, a female thread is formed at the base end of the angle adjusting plate 31, which engages with a male threaded adjusting component 45 located at the front end of the locking pin 41. The locking pin 41 is a hollow, bottomed cylindrical shape, and a locking pin force-applying mechanism 42 is installed inside the base end side. The front end of the locking pin force-applying mechanism 42 abuts against the sliding shaft 57 of the second rotor 55, always applying force to the locking pin 41 towards the base end side.

[0090] Therefore, similar to the first embodiment, by inserting the adjuster key 80 into the locking mechanism 40 and rotating it a predetermined number of times, the locking pin 41 rotates together with the adjuster component 45, thereby adjusting the relative position of the screwed angle adjustment piece 31.

[0091] Figure 17 and Figure 19 The angle adjustment mechanism 30 is closest to the adjuster component 45 in the state of being short in length. Figure 17 It is in the unlocked state. Figure 19 It is in the locked state. In this case, because the lengths of the adjuster component 45 and the angle adjustment mechanism 30 are short, it is possible to achieve the following: Figure 19 When the locking pin 41 is pushed in as shown, the angle adjustment piece 31 penetrates shallowly into the base 22, 22 of the insert pieces 20, 20, so that the opening angle of the insert pieces 20, 20 becomes the first opening angle θ1.

[0092] On the other hand, by using the adjuster key 80 to rotate the second rotor 55 a specified number of revolutions, such as... Figure 20 , Figure 21 The position of the angle adjustment piece 31 relative to the adjuster component 45 is changed, which can change the insertion depth of the angle adjustment piece 31 into the bases 22, 22 when the locking pin 41 is pushed in, and can adjust the opening angle of the insert pieces 20, 20 to a second opening angle θ2 for a safety slot with an opening width of 6mm. Figure 20 ) or the opening angle θ2' for a safety slot with an opening width of 7mm ( Figure 21 )wait.

[0093] Of course, the opening angle is not limited to the above and can be adjusted to different opening angles.

[0094] <Version 3> The second embodiment, as described above, has a screw-in structure where the angle adjustment mechanism 30 has a female thread and the adjuster component 45 has a male thread. However, in the third embodiment, the adjuster component 45 of the first embodiment, which protrudes from the locking pin 41, is used. Figures 22 to 27 As shown, a spiral-shaped infeed portion 33 is formed in the angle adjustment mechanism 30, and the relative lengths of the angle adjustment mechanism 30 and the locking pin 41 are adjusted. Since the adjuster component 45 rotates relative to the spiral-shaped infeed portion 33 of the angle adjustment mechanism 30, the length can be adjusted. Therefore, similar to the second embodiment, it includes a configuration in which the angle adjustment mechanism 30 and the adjuster component 45 are screwed together.

[0095] Angle adjustment mechanism 30 Figure 22 , Figure 23 and magnified 3D Figure 24As shown, an angle adjustment piece 31 protrudes from the front end, and a spiral-shaped cut-in portion 33 is formed on the base end side. The adjuster component 45 is embedded in the cut-in portion 33.

[0096] If the second rotor 55 is rotated using the adjuster key 80, then, as in the second embodiment, the locking pin 41 rotates, and the adjuster component 45 also rotates integrally. Thus, the adjuster component 45 moves within the angle adjustment mechanism 30 while rotating spirally within the insertion portion 33 formed in the angle adjustment mechanism 30. Therefore, as in the second embodiment, as... Figures 25 to 27 As shown, the opening angles of the insert pieces 20, 20 can be adjusted to θ1, θ2, θ2', etc.

[0097] <4th Embodiment> In the above embodiments, after the opening angle of the insert pieces 20, 20 is adjusted in advance using the adjuster key 80, the opening angle of the insert pieces 20, 20 is locked by pushing in the locking pin 41. In the fourth embodiment, as... Figures 28 to 33 As shown, the disclosed structure omits the locking pin 41 and directly adjusts the insertion amount of the angle adjustment mechanism 30 to match the opening width of the safety slot and locks it.

[0098] The anti-theft connection device 10 in this embodiment is as follows: Figure 28 and Figure 29 As shown, a pair of housing halves 73 and 74 are joined to form a housing 70. The housing halves 73 and 74 have insertion claws 21 and insertion tab protrusions 27 on their front end sides, and are tapered at their base ends. The tapered base ends have openings on both sides, and a portion of the angle adjustment mechanism 30 protrudes from the side.

[0099] Inside the housing 70, the insert pieces 20, 20 are forced in the closing direction by the insert piece force application mechanism 25, which is composed of a coil spring. Furthermore, an angle adjustment mechanism 30 is provided on the base end side of the housing 70, which is movable from the base end side toward the front end side.

[0100] Angle adjustment mechanism 30 Figure 29 As shown, an angle adjustment piece 31 is formed at the front end, and user-operated grip portions 37 are formed on both sides of the base end. Furthermore, a positioning hole 38 is provided through the grip portions 37. The positioning hole 38 of the angle adjustment mechanism 30 can be aligned with a plurality of locking holes 75a, 75b, and 75c formed in the housing 70. By aligning the positioning hole 38 with a certain locking hole 75a, 75b, or 75c, and passing the purse lock or wire component through the neatly arranged positioning hole 38 and locking hole 75a, 75b, or 75c, the angle adjustment mechanism 30 can be locked relative to the housing 70.

[0101] The locking holes 75a, 75b, and 75c are in their open positions when the device is in the unlocked state. Figure 30 The position pushes the angle adjustment mechanism 30 towards the front end, and the opening angle of the insert pieces 20 and 20 is as follows: Figures 31 to 33 As shown, the opening angles are θ1, θ2, and θ2', respectively, and the holes are positioned opposite each other at the positioning holes 38. That is, in the state shown... Figure 31 With the positioning hole 38 aligned with the locking hole 75a on the base side as shown, the angle adjustment mechanism 30 adjusts the opening angle of the insert pieces 20, 20 to θ1. Figure 32 Adjust the opening angle to θ2 when the hole is aligned with the locking hole 75b as shown. Figure 33 Adjust the opening angle to θ2' when the hole is aligned with the locking hole 75c as shown.

[0102] In addition, the angle adjustment mechanism 30, such as Figure 29 As shown, a positioning member 39 is provided between the handle portions 37 and 37. The positioning member 39 can be made into an outwardly shaped, mountain-like leaf spring, embedded in multiple positioning recesses 76, 76a, 76b, and 76c formed on the inner surfaces of the housing halves 73 and 74, which can temporarily determine the position of the angle adjustment mechanism 30. That is, when the angle adjustment mechanism 30 is in the unlocked position (…),… Figure 30 The above Figures 31 to 33 When the position is reached, the positioning component 39 is embedded in the positioning recesses 76, 76a, 76b, and 76c, which can softly lock the angle adjustment mechanism 30.

[0103] Therefore, from Figure 30 In the unlocked position shown, insert pieces 20, 20 are inserted into the safety slot, and handle 37 is pushed forward. This causes angle adjustment piece 31 to penetrate between the bases 22, 22 of insert pieces 20, 20, adjusting the opening angle of insert pieces 20, 20. Then, if angle adjustment mechanism 30 is pushed into the desired opening angle, the positioning hole 38, corresponding to the opening width of the safety slot, is positioned as follows: Figures 31 to 33 As shown, they are neatly arranged with a locking hole 75a, 75b or 75c. At this time, the angle adjustment mechanism 30 will not shift its position even if the user releases his hand from the handle part 37, because the positioning member 39 is inserted into the positioning recess 76a, 76b or 76c.

[0104] Then, by passing the purse lock or dial lock and the cable component through the neatly arranged positioning holes 38 and locking holes 75a, 75b or 75c, the angle adjustment mechanism 30 is locked to the housing 70, and the anti-theft connection device 10 is connected to the security slot. Simply connect the cable component to the purse lock, etc., and connect the other end of the cable component to a table or pillar.
