Description

General portable electronic device anti-theft lock

Technical Field

The present invention relates to the field of anti-theft locks, and more particularly to an anti-theft lock for a portable electronic device.

Background

Portable electronic devices, such as notebook computers, are often provided with anti-theft lock holes, whereby a dedicated anti-theft lock can be combined with the portable electronic device to lock the portable electronic device to a desk or display case for anti-theft purposes during store display or to allow users to leave their seats temporarily in public places (e.g., libraries) without fear of theft. The anti-theft lock hole is a through hole formed in the outer wall of the portable electronic device in a penetrating manner. One end of the anti-theft lock is fixed on a table or a display cabinet through a steel cable, and the other end of the anti-theft lock is provided with a clamping jaw. The outer end of the claw can penetrate into the casing through the anti-theft lock hole and can be expanded in the casing to enable the claw to be clamped and fixed in the anti-theft lock hole and cannot be pulled out, and therefore the electronic device is fixed on a table or a display cabinet. The anti-theft lock holes have various specifications, the opening widths of the anti-theft lock holes with different specifications are different, and the thicknesses of the outer walls of the machine shell of the portable electronic device are different.

However, the claws of each type of anti-theft lock can only be opened and fixed at a specific opening position, that is, the claws can only be opened to a specific width, so that each type of anti-theft lock can only be used with a specific anti-theft lock hole, which is very troublesome and expensive. For example, once a user purchases pens with different specifications, a new anti-theft lock must be purchased; if a store shows a plurality of pen power supplies with different specifications at the same time, a plurality of anti-theft locks with different specifications must be prepared, which causes the use to be troublesome and the cost to be high.

More specifically, the electrical anti-theft keyhole is mainly composed of three major systems, namely, Kensington Slot, Noble Wedge Slot, and Kensington Nano Slot. Kensington Slot ™ with addition of a round-angle hole in addition to the standard square keyhole; noble Wedge Slot plus Wedge-shaped hole with 3mm to 5mm square lock hole (such as DELL) and other 5 kinds of lock hole; after multiple field market tests, it is found that the above 5 kinds of apertures have different specifications due to different electrical specifications of each factory, such as thick and thin iron sheets for anti-theft lock holes. The pen electric machine body is thick and thin. The distance between the anti-theft lock hole iron sheet and the pen-electricity machine body is different, so that the anti-theft lock can not be used universally.

Therefore, a new technical solution is needed to solve the above problems.

Disclosure of Invention

In view of the above, the present invention is directed to a portable electronic device with an anti-theft lock, which is suitable for various anti-theft lock holes with different widths, and can achieve stepless adjustment.

In order to achieve the purpose, the invention adopts the following technical scheme:

a universal portable electronic device anti-theft lock includes:

a lock case; the inside of the lock shell is provided with a channel, and one end of the channel at one end of the lock shell is provided with an opening;

a lock head component, an opening rod and two buckle components; the lock head assembly, the opening rod and the two buckling pieces are arranged in the passage of the lock shell and are sequentially arranged towards the opening at the head end; wherein, the lock head component is provided with an operating piece for controlling the sliding of the opening rod in the channel; one end of the opening rod, which faces the head end opening, is defined as an abutting end; the inner ends of the two buckling pieces are positioned in the channel and pivoted with the lock shell, and the inner ends of the two buckling pieces are respectively positioned at two opposite sides of the opening rod; the outer ends of the two fasteners protrude out of the lock shell from the head end opening; the two fasteners are provided with: an inner side surface facing the other fastener, an outer side surface arranged opposite to the inner side surface, and an electronic device clamping part which is formed on the outer side surface in a protruding manner and is positioned at the outer end; the movement of the opening rod towards the opening of the head end can enable the abutting end to abut against the inner side surfaces of the two buckling pieces and enable the electronic device buckling parts of the two buckling pieces to gradually move towards directions away from each other.

Compared with the prior art, the anti-theft lock hole has obvious advantages and beneficial effects, and particularly, according to the technical scheme, the anti-theft lock hole is mainly characterized in that the lock shell, the lock head assembly, the opening rod and the buckle piece are arranged, the opening rod moves towards the opening at the head end of the channel of the lock shell, the abutting end of the opening rod abuts against the inner side surface of the buckle piece, and the clamping parts of the electronic devices of the two buckle pieces gradually move towards the directions far away from each other, so that the anti-theft lock hole is suitable for anti-theft lock holes with different widths, and the effect of stepless adjustment can be achieved.

Detailed Description

Fig. 1 to 9 show a specific structure of a first embodiment of the present invention.

Referring to fig. 1 to 3 and fig. 6, the anti-theft lock of the portable electronic device of the present invention is used to fasten an anti-theft lock hole 91. The present invention comprises a lock case 10, a lock head assembly 20, a displacement absorbing mechanism 30, an opening rod 40 and two fasteners 50; and in the present embodiment, further comprises a return elastic member 60.

The lock case 10 is formed with a passage 11 (as shown in fig. 3), the passage 11 is formed with a head opening 101 and a tail opening 102 at opposite ends of the lock case 10, and the lock cylinder assembly 20, the displacement absorbing mechanism 30, the opening rod 40 and the two fasteners 50 are disposed in the passage 11 and arranged in sequence from the tail opening 102 to the head opening 101. Specifically, the lock case 10 is formed by combining a lower housing 12 and an upper cover 13, and the channel 11 is formed by a substantially elongated slot formed in the lower housing 12.

In this embodiment, the channel 11 is bent, that is, the channel 11 has a fastening section 111 and a locking section 112, and the extending direction of the fastening section 111 is not parallel to the extending direction of the locking section 112. One end of the snap section 111 forms a head end opening 101. The opening rod 40 and the two locking elements 50 are disposed on the locking segment 111. One end of the locking head section 112 defines the rear opening 102, and the locking head assembly 20 is disposed in the locking head section 112. The displacement absorbing mechanism 30 has both ends respectively located at the snap section 111 and the lock section 112.

Referring to fig. 3 to 5, the lock cylinder assembly 20 is disposed in the rear opening 102 and has an operating member 21, and the operating member 21 movably penetrates through the rear opening 102 and can move to a locking position (as shown in fig. 4) in a direction of retracting into the channel 11. The lock head assembly 20 is a standard assembly in the prior art, and specifically a push lock, and the detailed structure thereof is not described again. When the operating member 21 of the cylinder assembly 20 is in the unlocking position (as shown in fig. 3), the user can manually press the operating member 21 to move the operating member 21 in the direction of retracting the operating member 21 into the channel 11 to the locking position, and the operating member 21 is fixed in the locking position by the mechanism in the cylinder assembly 20. To unlock the cylinder assembly 20, a key (not shown) is inserted into the cylinder assembly 20, which drives a mechanism in the cylinder assembly 20 to retract the operating member 21 to the unlocked position.

The aforementioned expanding rod 40 can slide in the channel 11, one end of the expanding rod 40 toward the head end opening 101 is defined as an abutting end 41, and the diameter of the abutting end 41 increases toward a direction away from the head end opening 101, that is, the diameter of the abutting end 41 increases toward the displacement absorbing mechanism 30, but not limited thereto.

The displacement absorbing mechanism 30 pushes against the operating member 21 and the spreader lever 40 of the lock cylinder assembly 20, and can push the operating member 21 and the spreader lever 40 away from each other, and make the spreader lever 40 tend to slide in a direction away from the operating member 21; that is, when the operating element 21 is located at the locked position, the displacement absorbing mechanism 30 can absorb the displacement of the operating element 21 relative to the spreader lever 40, and push the spreader lever 40 toward the head end opening 101 while the spreader lever 40 is moving relative to the operating element 21.

In the present embodiment, the displacement absorbing mechanism 30 includes an elastic member 31, and when the operating member 21 of the lock cylinder assembly 20 is located at the locking position, the elastic force of the elastic member 31 pushes the opening lever 40 away from the operating member 21. More specifically, the two ends of the elastic member 31 respectively push against the operating member 21 and the spreader lever 40, and the elastic member 31 is preferably a compression spring. The mode of driving the opening lever 40 by the displacement absorption mechanism 30 is not limited to the elastic force of the elastic member 31, and the opening lever 40 may be driven by the magnetic force of two magnetic members that repel each other as described in the second embodiment.

Referring to fig. 5 and 6, the inner end 51 of each of the aforementioned fasteners 50 is located in the channel 11 and pivotally installed on the lock housing 10, and the two inner ends 51 of the two fasteners 50 are respectively located at two opposite sides of the spreading rod 40. The outer end 52 of each catch 50 projects from the head opening 101 out of the lock housing 10.

Each fastener 50 has an inner side 53, an outer side 54 and an electronic device engaging portion 55. The inner side 53 defines a side of the fastener 50 facing the other fastener 50, and the outer side 54 is opposite to the inner side 53. The electronic device engaging portion 55 is formed to protrude from the outer side surface 54 and is located at the outer end 52. The fastener 50 is configured to penetrate through the anti-theft lock hole 91 of the electronic device, and after penetrating through the anti-theft lock hole 91, the electronic device engaging portion 55 abuts against an inner wall surface of the electronic device to limit that the fastener 50 cannot be pulled out from the anti-theft lock hole 91 (as shown in fig. 6).

For convenience of description, the two fasteners 50 are defined as a first fastener 501 and a second fastener 502 (as shown in fig. 6). A bump 56 is formed on the inner side 53 of the first locking member 501, and the bump 56 is closer to the outer end 52 than the inner end 51 of the first locking member 501. A protrusion slot 57 is concavely formed on the inner side surface 53 of the second locking member 502, and when the first locking member 501 and the second locking member 502 pivot towards each other, the protrusion 56 of the first locking member 501 can move into the protrusion slot 57 of the second locking member 502. The cam slot 57 allows the two latches 50 with the cam 56 to pivot towards each other without the cam 56 reducing the angle.

The two fasteners 50 in this embodiment have the same structure and only different positions, that is, a protrusion 56 is also formed on the inner side 53 of the second fastener 502, a protrusion slot 57 is formed on the inner side 53 of the first fastener 501 in a recessed manner, and the protrusion 56 of the second fastener 502 can move into the protrusion slot 57 of the first fastener 501.

Referring to fig. 6 to 9, the movement of the opening rod 40 toward the head end opening 101 causes the abutting end 41 of the opening rod 40 to abut against the two inner side surfaces 53 of the two fasteners 50 and causes the two electronic device engaging portions 55 of the two fasteners 50 to gradually move away from each other; that is, the included angle of the two fasteners 50 gradually increases as the spreader bar 40 moves toward the head end opening 101, so that the distance between the two electronic device engaging portions 55 gradually increases.

Referring to fig. 3 and 4, the elastic restoring element 60 drives the opening rod 40 away from the head opening 101. When the operating member 21 is in the locked position (as shown in fig. 4), the force applied to the opening lever 40 by the return elastic member 60 is smaller than the force applied to the opening lever 40 by the displacement absorbing mechanism 30; that is, when the operating member 21 is located at the locked position, the return elastic member 60 does not prevent the displacement absorbing mechanism 30 from driving the spreader lever 40 toward the head end opening 101.

When the operating element 21 moves to the unlocking position in the direction protruding out of the channel 11 (as shown in fig. 3), the force applied by the displacement absorbing mechanism 30 to the opening rod 40 decreases rapidly, so that the force of the return elastic element 60 is greater than the force of the displacement absorbing mechanism 30 to move the opening rod 40 away from the head end opening 101, and the included angle of the two locking elements 50 can be gradually reduced. In short, when the operating member 21 is disengaged from the locked position, the elastic return member 60 can automatically move the opening lever 40 away from the head end opening 101, so that the user can easily pull the fastener 50 out of the anti-theft lock hole 91.

The use mode of the invention is as follows:

referring to fig. 3 to 6, the lock cylinder assembly 20 is unlocked, and then the operating member 21 is manually pressed to move the operating member 21 to the locked position (as shown in fig. 4 and 6). At this time, the operating element 21 pushes the displacement absorbing mechanism 30 to push the expanding rod 40 toward the head end opening 101, so that the expanding rod 40 forces the two electronic device engaging portions 55 of the two locking elements 50 to move away from each other, thereby locking the anti-theft lock hole 91.

Referring to fig. 6 to 9, when the operating element 21 moves to the locking position, the displacement absorbing mechanism 30 can force the two electronic device engaging portions 55 of the two locking elements 50 to move away from each other through the opening rod 40 until the locking elements 50 are limited by the width of the anti-theft lock hole 91, so as to achieve the effect of stepless adjusting the distance between the two electronic device engaging portions 55, that is, on the premise that the operating element 21 is located at the same locking position, the locking elements 50 can lock the anti-theft lock holes 91, 91A (shown in fig. 7), 91B (shown in fig. 8), and 91C (shown in fig. 9) with different widths. The abutting end 41 of the opening bar 40 can abut against the protrusion 56 of the first fastener 501, thereby increasing the distance between the two electronic device engaging portions 55 to engage the wider anti-theft lock hole 91.

When the present invention is separated from the anti-theft lock hole 91, the operating element 21 is retracted to the unlocking position in a direction protruding out of the channel 11.

The advantage of the non-parallel extending direction of the buckle section 111 and the lock section 112 is that when the present invention is used with a notebook computer (not shown), the buckle section 111 will be in a flat position against the desktop in cooperation with the position of the anti-theft lock hole 91 of the notebook computer, and at this time, the lock section 112 is non-parallel to the buckle section 111, so the tail opening 102 of the lock section 112 can tilt upwards, and the lock assembly 20 is convenient to operate.

As described above, the actuator 21 of the lock cylinder assembly 20 indirectly drives the opening lever 40 through the displacement absorbing mechanism 30, and the movement of the opening lever 40 gradually opens the two electronic device engaging portions 55 (i.e., moves in a direction away from each other), so that when the actuator 21 is moved to the locked position, the displacement absorbing mechanism 30 can continuously push the opening lever 40 in the direction of the head end opening 101 to open the two electronic device engaging portions 55 until the latch 50 is limited by the width of the anti-theft lock hole 91, and the present invention is applied to anti-theft lock holes 91 with different widths, thereby achieving the effect of stepless adjustment. In other words, when the operating element 21 is moved to the same locking position, the two locking elements 50 of the present invention can be spread apart and fixed at a plurality of spreading positions, unlike the locking element 50 of the conventional anti-theft lock which can only be spread apart to a single spreading position, thereby enabling the present invention to be applied to various anti-theft lock holes 91 with different widths.

Referring to fig. 10, a specific structure of a second embodiment of the present invention is shown.

The second embodiment of the present invention is substantially the same as the first embodiment, except that the displacement absorbing mechanism 30A includes two magnetic members 31A. The two magnetic members 31A repel each other, and the two magnetic members 31A are respectively disposed on the operation member 21A and the opening lever 40A of the lock cylinder assembly 20A. When the operating member 21A of the lock cylinder assembly 20A is located at the locking position, the repulsive force between the two magnetic members 31A pushes the opening lever 40A in a direction away from the operating member 21A.

Please refer to fig. 11 to 12, which illustrate a third embodiment of the present invention.

The third embodiment of the present invention is substantially the same as the first embodiment, except that the displacement absorption mechanism 30B comprises an elastic member 31B, a first turning block 32B and a second turning block 33B, thereby making the displacement absorption mechanism 30B suitable for the case that the bending amplitudes of the locking segment 111B and the locking segment 112B are large. Specifically, the snap section 111B is substantially perpendicular to the lock head section 112B.

The first turning block 32B is slidably disposed on the locking head section 112B along the extending direction of the locking head section 112B, and is formed with a first abutting surface 321B; the first abutting surface 321B is preferably a plane inclined to the extending direction of the lock cylinder segment 112B. The second turning block 33B is slidably disposed on the fastening section 111B along the extending direction of the fastening section 111B, and a second abutting surface 331B is formed; the second pushing surface 331B is preferably a plane inclined to the extending direction of the fastening section 111B. The second abutting surface 331B abuts against the first abutting surface 321B of the first turning block 32B in a relatively slidable manner. Sliding of the first diverter block 32B toward the second diverter block 33B along the direction of extension of the lock cylinder segment 112B forces the second diverter block 33B to slide toward the head end opening 101B; thus, the movement of the operating member 21B of the lock cylinder assembly 20B along the lock cylinder section 112B is converted into the movement of the second turning block 33B along the locking section 111B, so that the operating member 21B can drive the components in the locking section 111B under the condition that the bending amplitude of the channel 11B is large and even vertical.

In the present embodiment, the elastic member 31B is disposed between the second turning block 33B and the expanding rod 40B, and makes the second turning block 33B and the expanding rod 40B tend to move away from each other, but not limited to this, the elastic member 31B may be disposed between the first turning block 32B and the operating element 21B.

The elastic member 31B of the present embodiment can be replaced by two mutually exclusive magnetic members 31A, and the two mutually exclusive magnetic members 31A can be respectively disposed on the second turning block 33B and the opening rod 40B, the first turning block 32B and the opening rod 40B, or the first abutting surface 321B of the first turning block 32B and the second abutting surface 331B of the second turning block 33B.

Please refer to fig. 13 to 24, which show the fourth embodiment of the present invention.

The anti-theft lock of the portable electronic device of the present invention is used to pass through and fasten an anti-theft lock hole 91. The present invention comprises a lock case 10, a lock head assembly 20, a lock assembly 23, a displacement absorbing mechanism 30, a prop rod 40 and two fasteners 50; and in the present embodiment, further comprises a return elastic member 60.

The lock case 10 is formed with a passage 11, the passage 11 extends along an extension line L and is formed with a head end opening 101 and a tail end opening 102 at two opposite ends of the lock case 10, and the lock assembly 23, the displacement absorbing mechanism 30, the opening rod 40 and the two fasteners 50 are sequentially disposed along the extension line L toward the head end opening 101. In the embodiment, the lock case 10 is formed by combining a lower seat 12 and an upper cover 13, the channel 11 is an elongated slot formed on the top surface of the lower seat 12, and the lock case 10 may further include a middle partition plate disposed between the lower seat 12 and the upper cover 13, and the middle partition plate may have a through hole. The extension line L is preferably a straight line, but not limited thereto, and the extension line L may be appropriately bent.

The lock cylinder assembly 20 is disposed on one side of the housing 10 and has a lock block 22, the lock block 22 being movably disposed in the passage 11. The lock head assembly 20 is a standard assembly in the prior art, and can be locked or unlocked by a key or a password, and the detailed structure thereof is not repeated. Referring to fig. 15, 16, 19 and 20, the lock cylinder assembly 20 of the present embodiment is configured to move the lock block 22 around the centerline C of the lock cylinder assembly 20 after inserting a key (not shown), so that the key can move the lock block 22 to the rear opening 102 of the lock shell 10 and cover part of the rear opening 102, and the lock cylinder assembly 20 is defined as a locked state (as shown in fig. 16 and 20); alternatively, the key may be used to remove the lock block 22 from the rear opening 102, with the lock cylinder assembly 20 defining an unlocked state (as shown in fig. 15 and 19).

Referring to fig. 15 to 18, the lock assembly 23 is slidable relative to the lock case 10, and has an operating member 21 and a limiting member 32; and in this embodiment further has a stopper elastic member 33. The operating member 21 slidably penetrates through the rear opening 102 and can slide toward the head opening 101 to a locked position (as shown in fig. 16 and 18) or slide away from the head opening 101 to an unlocked position (as shown in fig. 15 and 17). The stopper 32 is provided on the operating element 21 and protrudes from a side surface of the operating element 21 facing the cylinder assembly 20. When the operating member 21 is in the above-mentioned locked position, the position-limiting member 32 is located in the passage 11 and abuts against the lock block 22 of the lock cylinder assembly 20 or an inner wall of the lock case 10 to limit the operating member 21 in the locked position. When the operating member 21 is located at the unlocking position, the limiting member 32 is located outside the lock case 10, but not limited thereto.

In the embodiment, the operating member 21 is provided with a receiving slot 311 recessed toward a side of the lock cylinder assembly 20; the limiting member 32 is long, and the limiting member 32 is pivoted to the operating member 21 toward one end of the head end opening 101 and is located in the accommodating groove 311. The position-limiting elastic element 33 is a compression spring, two ends of the compression spring respectively abut against the position-limiting element 32 and the bottom of the receiving slot 311, so that one end of the position-limiting element 32 away from the head opening 101 tends to protrude out of the receiving slot 311, that is, when the position-limiting element 32 protrudes out of the receiving slot 311, the position-limiting element 32 is inclined, so that even if the lock block 22 is located at the tail opening 102 and covers part of the tail opening 102 (i.e., the lock head assembly 20 is in a locked state), the user can still force the operation element 21 to move from the unlocked position to the locked position.

The position-limiting elastic element 33 is not limited by a compression spring, and only needs to make one end of the position-limiting element 32 tend to protrude out of the receiving slot 311. In addition, the limiting member 32 is not limited to the pivoting operation member 21, for example, the limiting member 32 can move linearly relative to the operation member 21.

The displacement absorbing mechanism 30 causes the operating element 21 and the opening lever 40 of the locking unit 23 to tend to slide away from each other. In the present embodiment, the displacement absorbing mechanism 30 is an elastic member, and specifically, a compression spring. Both ends of the displacement absorbing mechanism 30 respectively push against the operating element 21 and the opening lever 40. The displacement absorbing mechanism 30 is not limited to this, and other components may be provided in addition to the elastic member, as long as the displacement absorbing mechanism 30 makes the operating member 21 and the expanding lever 40 tend to slide away from each other by the elastic force of the elastic member. In addition, the displacement absorbing mechanism 30 may drive the operation element 21 and the opening lever 40 by the repulsive force of the two magnetic members as in the second embodiment of the present invention.

The opening rod 40 is slidably disposed in the channel 11 along the extension line L; the end of the spreader lever 40 remote from the rear opening 102 of the lock housing 10 defines an abutment end 41. The width of the abutting end 41 of the spreader bar 40 increases toward the rear opening 102, but not limited thereto.

The inner end 61 of each fastener 50 is located in the channel 11 and pivoted to the lock case 10; the two inner ends 61 of the two fasteners 60 are respectively located at two opposite sides of the spreader bar 40. The outer end 62 of each catch 50 projects from the head opening 101 out of the lock housing 10.

Each fastener 50 has an inner side 63, an outer side 64 and an electronic device engaging portion 55. The inner side 63 defines a side of the fastener 50 facing the other fastener 50, and the outer side 64 is opposite to the inner side 63. The electronic device engaging portion 55 is formed to protrude from the outer surface 64 and is located at the outer end 62. The fastener 50 is configured to penetrate through the anti-theft lock hole 91 of the electronic device, and after penetrating through the anti-theft lock hole 91, the electronic device engaging portion 55 abuts against an inner wall surface of the electronic device to limit that the fastener 50 cannot be pulled out from the anti-theft lock hole 91.

Referring to fig. 18 and fig. 24, for convenience of description, the two locking elements 50 are defined as a first locking element 501 and a second locking element 502, respectively. A bump 56 is formed on the inner side 63 of the first locking member 501, and the bump 56 is closer to the outer end 62 than the inner end 61 of the first locking member 501. A protrusion slot 57 is concavely formed on the inner side 63 of the second locking member 502, and when the first locking member 501 and the second locking member 502 pivot toward each other, the protrusion 56 of the first locking member 501 can move into the protrusion slot 57 of the second locking member 502. The tab slot 57 allows the two latches 60 with the tab 56 to pivot toward each other without the tab 56 reducing the angle.

The two fasteners 50 in this embodiment have the same structure and only different positions, that is, a protrusion 56 is also formed on the inner side 63 of the second fastener 502, a protrusion slot 57 is formed on the inner side 63 of the first fastener 501 in a recessed manner, and the protrusion 56 of the second fastener 502 can move into the protrusion slot 57 of the first fastener 501.

Referring to fig. 17 and fig. 21 to fig. 24, the movement of the opening rod 40 toward the head end opening 101 causes the abutting end 41 of the opening rod 40 to abut against the two inner side surfaces 63 of the two fasteners 50 and causes the two electronic device engaging portions 55 of the two fasteners 50 to gradually move away from each other; that is, the included angle of the two fasteners 50 gradually increases as the spreader bar 40 moves toward the head end opening 101, so that the distance between the two electronic device engaging portions 55 gradually increases.

Referring to fig. 17 and 18, the restoring elastic member 60 drives the opening rod 40 toward the rear opening 102. When the operating member 21 is located at the locked position, the force applied to the opening lever 40 by the return elastic member 60 is smaller than the force applied to the opening lever 40 by the displacement absorbing mechanism 30; that is, when the operating element 21 is located at the locked position, the return elastic member 60 does not prevent the displacement absorbing mechanism 30 from driving the spreader lever 40 to move in the direction of the head end opening 101.

When the operating element 21 moves away from the head opening 101 to the unlocking position, the force applied to the spreader bar 40 by the displacement absorbing mechanism 30 decreases rapidly, so that the force of the restoring elastic element 60 is greater than the force of the displacement absorbing mechanism 30 to move the spreader bar 40 toward the tail opening 102, and the included angle of the two locking elements 50 can be gradually reduced. In short, when the operating member 21 is disengaged from the locked position, the elastic return member 60 can automatically move the opening bar 40 toward the rear opening 102, so as to facilitate the user to pull the fastener 50 out of the anti-theft lock hole 91.

The use mode of the invention is as follows:

referring to fig. 15, 17 and 19, the lock cylinder assembly 20 is first unlocked, that is, the lock block 22 is not located at the rear opening 102. At this time, the operating member 21 of the locking assembly 23 is driven by the displacement absorbing mechanism 30 to move in a direction away from the spreader lever 40 (i.e., in a direction toward the head end opening 101) to the unlocking position. The two fasteners 50 are pivoted to each other to enable the two electronic device engaging portions 55 to be adjacent to each other, and then the two electronic device engaging portions 55 penetrate through to the other side of the anti-theft lock hole 91.

Referring to fig. 16, 18 and 20, the operating element 21 is pressed by hand to move the operating element 21 to the locking position, and the position-limiting element 32 is moved into the channel 11 of the lock case 10 by the operating element 21. Then, the lock cylinder assembly 20 is switched to the locking state, that is, the lock block 22 is moved to the rear opening 102 of the lock housing 10 and covers part of the rear opening 102, so that the lock block 22 is located at one side of the position-limiting member 32 facing the rear opening 102, and thus the position-limiting member 32 abuts against the lock block 22 to limit the operation member 21 at the locking position. At this time, the displacement absorbing mechanism 30 is pushed by the operating element 21, so that the displacement absorbing mechanism 30 pushes the opening rod 40 towards the direction of the head end opening 101, and the opening rod 40 drives the two electronic device engaging portions 55 of the two locking elements 50 to move towards a direction away from each other, thereby locking the anti-theft lock hole 91.

In the embodiment, the limiting member 32 can be retracted into the containing groove 311 of the operating member 21, so that the lock head assembly 20 can be switched to the locked state first, and then the operating member 21 is pressed to move the operating member 21 to the locked position; that is, regardless of the state of the lock cylinder assembly 20, the user can move the operating member 21 to the locked position, which is convenient for use.

Referring to fig. 18 and fig. 21 to fig. 24, when the operating element 21 moves to the locking position, the displacement absorbing mechanism 30 can force the two electronic device engaging portions 55 of the two locking elements 50 to move away from each other through the opening rod 40 until the locking elements 50 are limited by the width of the anti-theft lock hole 91 and cannot be opened continuously, so as to achieve the effect of stepless adjusting the distance between the two electronic device engaging portions 55, that is, on the premise that the operating element 21 is located at the same locking position, the locking elements 50 can lock the anti-theft lock holes 91, 91A, 91B and 91C with different widths. Referring to fig. 10 and 12, the abutting end of the spreading rod 40 can abut against the protrusion 56 of the first fastener 501, so as to increase the distance between the two electronic device engaging portions 55 to engage the wider anti-theft lock hole 91.

When the anti-theft lock of the electronic device of the present embodiment is separated from the anti-theft lock hole 91, the lock head assembly 20 is returned to the unlocking state.

Regarding the specific structure of the fourth embodiment, it can also be seen that the anti-theft lock for portable electronic device of the present invention comprises a lock housing 10, a lock head assembly 20 and a locking assembly, the locking assembly is disposed in the channel 11 of the lock housing 10 and includes the aforesaid operating element 21, limiting element 32, displacement absorbing mechanism 30, opening rod 40 and two locking elements 50, the operating element 21, the displacement absorbing mechanism 30, the opening rod 40 and the two locking elements 50 are sequentially disposed along the extension line L toward the head end opening 101.

Please refer to fig. 25 to 27, which illustrate a fifth embodiment of the present invention.

The fifth embodiment of the present invention is substantially the same as the fourth embodiment, except that the cylinder assembly 20A is a combination lock, and the cylinder assembly 20A functions not to restrict the operating member 21A to the locked position but to disengage the operating member 21A from the locked position. In the present embodiment, when the operating element 21A is located at the locking position, the limiting element 32A protrudes from the receiving slot 311A and abuts against the inner wall of the lock case 10A to limit the operating element 21A at the locking position (as shown in fig. 26), that is, the lock cylinder assembly 20A of the second embodiment does not have the function of limiting the position of the operating element 21A, but instead, the lock case 10A limits the operating element 21A at the locking position. When the lock cylinder assembly 20A inputs the correct number, the user can manually press the lock block 22A, so that the lock block 22A pushes the limiting member 32A of the locking assembly 23A to force the limiting member 32A to retract into the receiving groove 311A, and the operating member 21A automatically rebounds to the unlocking position (as shown in fig. 27).

In addition, the displacement absorbing mechanism 30A in the second embodiment includes two magnetic attraction pieces 31A, the two magnetic attraction pieces 31A are respectively disposed on the operating piece 21A and the opening lever 40A of the locking assembly 23A, and the two magnetic attraction pieces 31A repel each other to move the operating piece 21A and the opening lever 40A away from each other; however, the displacement absorbing mechanism 30A may further include other components, as long as the displacement absorbing mechanism 30A makes the operating element 21A and the opening lever 40A tend to slide away from each other by the repulsive force between the two magnetic attracting elements 31A.

Please refer to fig. 28 to 29, which show the structure of the sixth embodiment of the present invention.

The sixth embodiment of the present invention is substantially the same as the fourth embodiment, except that the cylinder assembly 20B is movable up and down integrally with respect to the housing 10B, and the cylinder assembly 20B does not have the function of restricting the position of the operating member 21B, but the operating member 21B is restricted to the locked position by the inner wall of the housing 10B as in the second embodiment. The lock block 22B of this embodiment is movable in a circling manner as in the first embodiment. To automatically rebound the operating element 21B to the unlocking position, the lock block 22B is moved above the position-limiting element 32B and the lock cylinder assembly 20B is pressed downward (as shown in fig. 28), so that the operating element 21B automatically rebounds to the unlocking position (as shown in fig. 29, but the lock block 22B in fig. 17 has been moved away from above the position-limiting element 32B).

Please refer to fig. 30 to 44, which show a seventh embodiment of the present invention.

Referring to fig. 30 to 33, the anti-theft lock for portable electronic device of the present invention includes a fastening mechanism 14, a resilient return element 60, a control element 70 and a lock head assembly 20.

The buckling mechanism 14 includes a lock housing 10, an opening rod 40 and two fasteners 50. In the present embodiment, the lock case 10 specifically includes a lower seat 12 and an upper cover 13. The lower base 12 has an inner space and an engaging direction S (as shown in fig. 33), and a head end opening 101 is formed at an end of the lower base 12 facing the engaging direction S, and the head end opening 101 communicates with the inner space of the lower base 12. The lock case 10 is not limited thereto, and may be a plate body installed inside other components.

The opening lever 40 is slidably provided on the lower base 12 of the lock case 10 in the engaging direction S. One end of the opening rod 40 facing the fastening direction S is defined as an abutting end 41, and the width of the abutting end 41 is gradually reduced toward the fastening direction S. Specifically, the spreading bar 40 has two guiding inclined surfaces 122, and the two guiding inclined surfaces 122 are respectively disposed on two opposite sides of a central line C1 (shown in fig. 33) of the spreading bar 40, are inclined to the central line C1 of the spreading bar 40, and extend to the end surface of the abutting end 41 in the fastening direction S. The spacing distance between the two guiding slopes 122 is gradually reduced toward the buckling direction S.

The two fasteners 50 are both long. The inner end of each fastener 50 is pivoted to the lower seat 12 of the lock case 10 and is located in the inner space of the lower seat 12. The two inner ends of the two fasteners 50 are respectively located at two opposite sides of the spreader bar 40. The two outer ends of the two fasteners 50 protrude out of the lock case 10 from the head end opening 101 of the lower base 12.

Each fastener 50 has an inner side 51, an outer side 52 and an electronic device engaging portion 55, the inner side 51 is a side of the fastener 50 facing the other fastener 50, the outer side 52 is disposed opposite to the inner side 51, and the electronic device engaging portion 55 is formed on the outer side 52 in a protruding manner and located at an outer end of the fastener 50.

Referring to fig. 33 and 34, the movement of the opening rod 40 in the fastening direction S causes the abutting end 41 of the opening rod 40 to abut against the two inner side surfaces 51 of the two fasteners 50, so that the two fasteners 50 pivot in a direction away from each other, and the two electronic device engaging portions 55 of the two fasteners 50 gradually move in a direction away from each other.

Referring to fig. 32 and 35, in the present embodiment, the two locking elements 50 have the same shape, and only the installation angles are different, but the shapes of the two locking elements 50 are not limited to the same shape. For convenience of describing the detailed features of the locking element 50, the two locking elements 50 are defined as a first locking element 501 and a second locking element 502 (as shown in fig. 35). The inner side 51 of the first fastener 501 has a first abutting region 611, a protrusion 56 and a second groove 57, but the second groove 57 can be omitted as appropriate.

The first abutting region 611 is elongated and extends from the proximal end of the first snap 501 towards the distal end; more specifically, the first abutting region 611 is a plane extending linearly, but the first abutting region 611 is not limited to the plane, and may be an arc surface having a slight arc.

The protrusion 56 protrudes from the first abutting region 611 in the direction of the second locking element 62, and is connected to an end of the first abutting region 611 in the locking direction S. The abutment end 41 of the spreader lever 40 selectively abuts against the first abutment region 611 or the projection 56; the abutting end 41 of the opening lever 40 abuts against the first abutting region 611 first to pivot the first latch 501 away from the second latch 502, and then abuts against the protrusion 56 to pivot the first latch 501 continuously in the same direction during the sliding process of the opening lever 40 in the latching direction S. By forming the protrusion 56, the spreading bar 40 can more effectively pivot the two fasteners 50 away from each other.

The inner side 51 of the second locking element 502 has a second abutting area 621, a second protrusion 622 and a first groove, but the second locking element 502 may not have the second protrusion 622, that is, only the inner side 51 of one locking element 50 of the two locking elements 50 may have a protrusion. The second abutment region 621 is elongate. The second protrusion 622 protrudes from the second abutting region 621 toward the first locking member 501, and connects one end of the second abutting region 621 toward the locking direction S. The abutting end 41 of the spreader lever 40 selectively abuts the second abutting region 621 or the second protrusion 622.

When the first latch 501 and the second latch 502 pivot toward each other, the protrusion 56 of the first latch 501 can move into the first groove of the second latch 502, and the second protrusion 622 of the second latch 502 can move into the second groove 57 of the first latch 501, so that the outer end of the first latch 501 can pivot until abutting against the outer end of the second latch 502. By forming the second groove 57 and the first groove, the angle at which the first latch 501 and the second latch 502 pivot toward each other is not reduced by the bump 56 and the second protrusion 622; that is, the engagement of the protrusion and the groove can increase the extent to which the first catch 501 and the second catch 502 pivot in the direction away from each other due to the abutment of the spreader lever 40.

Furthermore, in the present embodiment, the protrusion 56 of the first fastener 501 has an abutting arc 6121, and when the abutting end 41 of the spreading lever 40 abuts against the protrusion 56, the abutting end 41 abuts against the abutting arc 6121 of the protrusion 56 to move the corresponding electronic device engaging portion 55. Similarly, the second protrusion 622 of the second latch 502 can also have an abutting arc 6221 (as shown in fig. 35), and when the abutting end 41 of the spreading lever 40 abuts against the second protrusion 622, the abutting end 41 abuts against the abutting arc 6221 of the second protrusion 622 to move the corresponding electronic device engaging portion 55.

Referring to fig. 32 to 34, the return elastic element 60 is connected to the spreading rod 40, and causes the spreading rod 40 to tend to move opposite to the buckling direction S and retract into the opening 101 at the head end of the lock case 10. Thus, the restoring elastic element 60 biases the opening lever 40 to allow the two fasteners 50 to pivot toward each other. The return elastic element 60 is specifically a compression spring sleeved outside the opening rod 40.

The control member 70 is rotatably disposed in the inner space of the lower housing 12 of the lock case 10 and is located on the opposite side of the opening lever 40 with respect to the fastening direction S. The control member 70 has a ring-shaped curved surface 71, and the ring-shaped curved surface 71 surrounds the rotation axis of the control member 70 and drives the opening rod 40 of the engaging mechanism 14 toward the engaging direction S. When the control member 70 rotates relative to the lock case 10, the curved ring surface 71 enables the position of the spreading rod 40 along the fastening direction S to change with the rotation angle of the control member 70 relative to the lock case 10, and further enables the distance between the two electronic device engaging portions 55 of the two fasteners 50 to change with the rotation angle of the control member 70 relative to the lock case 10.

Referring to fig. 30 and 31, the lock cylinder assembly 20 is disposed on the upper cover 13 of the lock case 10 and connected to the control member 70; specifically, the lock cylinder assembly 20 has a spindle 72 (shown in fig. 31), the spindle 72 passing through a hole in the center of the control member 70. The lock cylinder assembly 20 (not shown) has an unlocked state and a locked state. In the unlocked state, the lock cylinder assembly 20 is rotatable relative to the housing 10 and the control member 70 is rotated. In the locked state, the lock cylinder assembly 20 is not rotatable relative to the housing 10. In this embodiment, the lock cylinder assembly 20 is controllable by a key (not shown) to switch between the unlocked state and the locked state.

Referring to fig. 33 and 34, when the lock cylinder assembly 20 is in the unlocked state, the user can rotate the control member 70 through the lock cylinder assembly 20, so that the electronic device engaging portions 55 of the two fasteners 50 of the fastening mechanism 14 move away from each other and are locked in the groove-shaped anti-theft lock hole 91.

In the present embodiment, the lock cylinder assembly 20 directly abuts against the opening lever 40 via the annular curved surface 71 of the control member 70 to drive the opening lever 40 to move in the engaging direction S, but not limited thereto. In other embodiments, the locking head assembly 20 may also drive the opening rod 40 to move in the engaging direction S through the elastic or magnetic elements. The resilient member comprises, for example, a compression spring and the magnetic member comprises, for example, two mutually repelling magnetic members. In the present embodiment, the cylinder lock assembly 20 is exemplified as the cylinder lock assembly, but the invention is not limited thereto; in other embodiments, the lock cylinder assembly 20 may also be, for example, a push lock assembly, a combination lock assembly, or the like.

Referring to fig. 34 to 43, a user can change the position of the opening rod 40 by rotating the lock head assembly 20, and further change the distance between the two engaging portions 55 of the electronic device, so that the fastening mechanism 14 can be fastened to various anti-theft lock holes 91 with different widths, such as an anti-theft lock hole 91A with a width of 5mm (as shown in fig. 34 and 35), an anti-theft lock hole 91B with a width of 5.5 mm (as shown in fig. 36 and 37), an anti-theft lock hole 91C with a width of 6 mm (as shown in fig. 38 and 39), an anti-theft lock hole 91D with a width of 7 mm (as shown in fig. 40 and 41), and an anti-theft lock hole 91E with a long circular hole shape (as shown in fig. 42 and 43). The six anti-theft lock holes 91 are standard anti-theft lock holes in the market.

In summary, the movement of the expanding rod 40 of the locking mechanism 14 towards the locking direction S in the present invention can gradually expand the two locking elements 50 to be locked in the anti-theft lock hole 91, that is, as long as the expanding rod 40 is continuously pushed towards the locking direction S, the two locking elements 50 can be continuously expanded until the locking elements 50 are limited by the width of the anti-theft lock hole, so that the locking mechanism 14 is suitable for various anti-theft lock holes 91 with different widths, and the effect of stepless adjustment is achieved. In addition, by providing the protrusion on the locking member, the invention can lock the anti-theft lock hole 91 with a wider width without increasing the size of the locking mechanism 14, thereby reducing the volume.

Please refer to fig. 45, which shows a detailed structure of an eighth embodiment of the present invention.

The eighth embodiment of the present invention is substantially the same as the seventh embodiment, and the difference is that the bump 56A of the first locking member 61A has an abutting inclined surface 6121A, and the abutting end 41A of the opening rod 40A abuts against the inclined surface 6121A to move the corresponding electronic device locking portion 133A. The included angle α between the abutment inclined surface 6121A and the first abutment region 611A is preferably between 30 degrees and 40 degrees, so as to ensure that the opening rod 40A can reliably open the first fastener 61A. Specifically, the included angle α of the present embodiment is between 32 and 34 degrees. By providing the abutting inclined surface 6121A, when the opening bar 40A abuts against the first locking element 61A, the contact angle between the two is smaller than the included angle α and will not change rapidly, so that the amount of force required to push the opening bar 40A is more stable.

In addition, the latch mechanism 14A has a protrusion distance D1 and a latch distance D2. The protruding distance D1 is defined as the distance that the abutment slope 6121A of the first snap 61A protrudes from the first abutment region 611A. The fastening distance D2 is defined as a distance between the first abutting region 611A and the second abutting region 621A of the first fastening member 61A and the second fastening member 62A when the first abutting region 611A and the second abutting region 621A are parallel to each other. In the present embodiment, the ratio of the protruding distance D1 to the latching distance D2 is between 0.25 and 0.4, and precisely between 0.35 and 0.4, so that the maximum opening angle can be obtained on the premise of ensuring sufficient strength of the first latching member 61A.

Please refer to fig. 46, which shows a detailed structure of a ninth embodiment of the present invention.

The ninth embodiment of the present invention is substantially the same as the eighth embodiment, except that the angle α between the abutting inclined surface 6121B and the first abutting region 611B is between 36 and 38 degrees, and the ratio of the protruding distance D1 to the snap spacing D2 is between 0.25 and 0.3. By designing the included angle α of the abutting inclined surface 6121B to be slightly larger, the buckling mechanism 14B can obtain the same opening angle of the first buckling member 61B with a shorter stroke of the opening rod 40B, and the mechanism operates more rapidly.

The key point of the design of the invention is that the lock shell, the lock head component, the opening rod and the buckle piece are arranged, the opening rod moves towards the opening at the head end of the channel of the lock shell, the abutting end of the opening rod abuts against the inner side surface of the buckle piece, and the clamping parts of the electronic devices of the two buckle pieces gradually move towards the direction far away from each other, thereby being suitable for various anti-theft lock holes with different widths and achieving the effect of stepless adjustment.

Secondly, the operating piece indirectly drives the opening rod through the displacement absorption mechanism, and meanwhile, the two electronic device clamping parts are gradually opened (namely, the two electronic device clamping parts move towards directions far away from each other) through the movement of the opening rod, so that when the operating piece is moved to the locking position, the displacement absorption mechanism can continuously push the opening rod towards the direction of the opening at the head end to force the two electronic device clamping parts to be opened until the fastener is limited by the width of the anti-theft lock hole; in other words, when the operating element is moved to the same locking position, the two locking elements of the present invention can be spread and fixed at a plurality of spreading positions, unlike the conventional anti-theft lock in which the locking elements can only be spread to a single spreading position, so that the present invention can be applied to various anti-theft lock holes with different widths.
