In the following, in conjunction with the drawings and the preferred embodiments of this creation, the technical means adopted by this creation to achieve the predetermined creation purpose are further explained.

Please refer to Figure 1, Figure 2, and Figure 3. The universal anti-theft lock for portable electronic devices of this creation includes a base 11, a rope 12, a lock core 13, a mounting shaft 14, two fasteners 20, and a The clamping and restoring assembly 30, a supporting member 40, a control member 50, and a supporting and restoring member 60.

The base 11 has a mounting groove 111, an internal space 112, and a moving channel 113. The mounting groove 111 is recessed from the surface of the base 11 toward the internal space 112. One end of the moving passage 113 is connected to the internal space 112, and the other end is connected to the bottom of the installation groove 111. The rope 12 is provided on the base 11. The lock core 13 is disposed on the base 11 and includes a driving shaft 131, and the driving shaft 131 extends into the inner space 112. Two ends of the mounting shaft 14 are respectively arranged on two opposite side walls of the mounting groove 111.

Please further refer to FIG. 4, FIG. 5, and FIG. 6, each fastener member 20 has an inner end 21 and an outer end 22. The inner end 21 is movably sleeved on the mounting shaft 14, and the outer end 22 is located outside the mounting groove 111. Each card member 20 has a first point 23 and a second point 24 formed on the side facing away from the other card member 20. The distance between the two second points 24 of the two card members 20 is greater than the distance between the two card members 20. The distance between the first point 23. The second point 24 is adjacent to the outer end 22 compared to the first point 23. Thereby, when the two fasteners 20 are inserted side by side in the anti-theft lock hole, the position of the second point 24 of the two fasteners 20 is wider and can be fastened to the inside of the anti-theft lock hole, and the first of the two fasteners 20 The position of the connection line of point 23 is relatively narrow, which can penetrate and abut against the edge of the anti-theft lock hole.

The clamping reset component 30 is connected to the two card firmwares 20 and tends to move the two card firmwares 20 toward each other. Specifically, in this embodiment, the locking and resetting assembly 30 includes two locking elastic elements 31, and each locking elastic element 31 is a compression spring. The two clamping elastic elements 31 are respectively connected to the two clamping members 20. Each clamping elastic element 31 abuts between the corresponding clamping member 20 and the two opposite side walls of the mounting groove 111, and tends to push the two clamping members 20 toward each other. However, the specific structure of the clamping and resetting assembly 30 is not limited to the above, and a single tension spring may be connected to the two clamping members 20, or two magnets may be provided on the two clamping members 20 respectively.

The supporting member 40 is movably disposed in the moving channel 113 of the base 11 and has a linkage end 41 and a supporting end 42 opposite to each other. The linkage end 41 is in the inner space 112, and in this embodiment, the linkage end 41 has a circular arc surface. The abutment end 42 is located in the installation slot 111 and selectively abuts against the two fasteners 20 by an inclined surface by the movement of the abutment member 40.

The control member 50 is rotatably disposed in the inner space 112 of the base 11 and can be driven to rotate by the driving shaft 131 of the lock core 13. The control member 50 has a circular curved surface 51. The ring surface 51 surrounds the rotation axis of the control member 50 and can slidably abut against the linkage end 41 of the abutment member 40. When the control member 50 rotates, the circular curved surface 51 can push the abutment member 40 toward the outer ends 22 of the two fasteners 20, so that the abutment ends 42 of the abutment member 40 and the two fasteners 20 abut against each other with an inclined surface. The supporting member 40 pushes against the two card firmware 20 to make the two card firmware 20 move away from each other. The ring surface 51 has an unlocking point 511 and a plurality of locking points 512, and the control member 50 can abut against the supporting member 40 with the unlocking point 511 or one of the locking points 512. The unlocking point 511 selectively abuts against the linkage end 41 of the supporting member 40 by the rotation of the control member 50. When the control member 50 rotates until the unlocking point 511 abuts against the linkage end 41 of the abutment member 40, the circular curved surface 51 does not push the abutment member 40 toward the outer ends 22 of the two fasteners 20. Each of the locking points 512 selectively abuts against the linkage end 41 of the supporting member 40 by the rotation of the control member 50. The distances between the locking points 512 and the axis of rotation of the control member 50 are not equal to each other, so that when the control member 50 rotates until any one of the locking points 512 abuts against the linkage end 41 of the supporting member 40, the circular curved surface 51 The distances for pushing the abutment member 40 toward the outer ends 22 of the two fasteners 20 are not the same; in other words, the locking points 512 enable the abutment member 40 to move toward the outer ends 22 of the two fasteners 20 at different distances.

Specifically, in this embodiment, the abutting relationship between the two fasteners 20 and the supporting member 40 is as follows. Each clamping member 20 includes an abutting inclined surface 25, and the abutting member 40 includes two abutting inclined surfaces 43. The supporting inclined surface 25 is formed on a side surface of the clamping member 20 facing the other clamping member 20, and the two supporting inclined surfaces 25 of the two clamping members 20 gradually approach each other in the direction toward the outer end 22. The two pushing inclined surfaces 43 are respectively formed on opposite sides of the abutting end 42, and the two pushing inclined surfaces 43 gradually approach each other in the direction toward the outer end 22. In this way, when the abutting member 40 moves toward the outer ends 22 of the two fasteners 20, the abutting member 40 can respectively abut against the abutting slopes 25 of the two fasteners 20 with the two abutting slopes 43, and support The pushing inclined surface 43 of the abutting member 40 slides relative to the supporting inclined surface 25 of the two fasteners 20. At this time, because the two abutting inclined surfaces 25 of the two clamping members 20 gradually approach each other in the direction toward the outer end 22, and the two abutting inclined surfaces 43 gradually approach each other in the direction toward the outer end 22, the abutting members 40 are facing both sides. The greater the distance that the outer end 22 of the card firmware 20 moves, the greater the distance between the two card members 20 away from each other.

However, in other embodiments, only each of the fasteners 20 may include a supporting inclined surface 25, or only the supporting member 40 may include two supporting inclined surfaces 43. In this way, the same effect can be achieved, that is, the supporting member 40 faces the two fasteners. The greater the distance the outer end 22 of 20 moves, the greater the distance the two card firmware 20 move away from each other.

The abutting and restoring member 60 is connected to the abutting member 40 and tends to make the abutting member 40 abut against the annular curved surface 51 of the control member 50. Specifically, in this embodiment, the supporting and restoring member 60 includes a supporting elastic element 61, and the supporting elastic element 61 is a compression spring. The supporting elastic element 61 abuts between the supporting member 40 and the base 11 and tends to push the supporting member 40 toward the control member 50. However, in other embodiments, the supporting and restoring member 60 can also be a tension spring or a magnet.

In addition, please further refer to FIG. 7 and FIG. 8. In this embodiment, in addition to the left and right opening and closing fastening of the two fasteners 20, the upper and lower fastening functions of the fastener 20 and the supporting member 40 are further included. The structure is as follows. Each clamping member 20 is rotatably sleeved on the mounting shaft 14 and includes a turning inclined surface 26 and a first buckle 27. The first buckle 27 is formed on the outer end 22 of the fastener 20 and extends in a direction away from the inclined surface 26. The supporting member 40 includes two pushing portions 44 and a second buckle portion 45. The second buckle portion 45 is formed on the abutment end 42 and extends in a direction opposite to the first buckle portion 27. When the abutting member 40 moves toward the outer ends 22 of the two fasteners 20, the two pushing and rotating parts 44 can respectively abut against the turning inclined surfaces 26 of the two fasteners 20, and slide relative to the turning inclined surfaces 26, thereby pushing against The two-card firmware 20 makes the two-card firmware 20 pivot about the mounting shaft 14 as an axis. When the abutting member 40 moves until the second buckle 45 protrudes out of the installation slot 111, the two pushing and rotating portions 44 respectively push against the rotating inclined surfaces 26 of the two fasteners 20.

That is to say, when the abutment member 40 moves toward the outer ends 22 of the two fasteners 20, the abutment member 40 can not only push and propagate the two fasteners 20 toward the left and right sides, but also can use the two pushing and rotating parts 44 Push against the rotating inclined surfaces 26 of the two fasteners 20 respectively, so that the two fasteners 20 pivot upwards with the mounting shaft 14 as the axis. At this time, the two fasteners 20 will be staggered up and down with the supporting member 40, thereby extending in opposite directions The first buckle 27 and the second buckle 45 can buckle up and down the periphery of the opening of the anti-theft lock hole.

The advantage of this creation is that the control member 50 is rotatably arranged in the inner space 112 of the base 11, and includes an annular curved surface 51 surrounding the rotation axis of the control member 50, and the supporting member 40 is movably arranged on the base. In the moving channel 113 of the seat 11, when the control member 50 rotates, the circular curved surface 51 of the control member 50 can push the butt member 40 toward the outer ends 22 of the two fasteners 20. In addition, the two fasteners 20 are movably sleeved on the mounting shaft 14, and the abutment ends 42 of the abutment member 40 and the two fasteners 20 selectively abut against each other by an inclined surface. When the outer end 22 of the fastener 20 moves, the abutting end 42 can abut against the fastener 20 with an inclined surface, thereby pushing the two fasteners 20 and keeping the two fasteners 20 away from each other. In addition, because the ring surface 51 of the control member 50 has a plurality of locking points 512, and the locking points 512 make the distance that the abutting member 40 moves toward the outer ends 22 of the two fasteners 20 are different from each other, the control member 50 One of the locking points 512 can be selected to abut against the abutment member 40, so that the abutment member 40 moves toward the outer ends 22 of the two fasteners 20 by different distances. In addition, the abutment ends 42 of the abutment member 40 and the two fasteners 20 are slanted against each other, so that the greater the distance that the abutment 40 moves toward the outer ends 22 of the two fasteners 20, the two fasteners 20 The greater the distance between each other. Furthermore, the ring surface 51 also has an unlocking point 511. When the control member 50 abuts against the linkage end 41 of the supporting member 40 with the unlocking point 511, the ring surface 51 does not push toward the outer ends 22 of the two fasteners 20 The supporting member 40 can thereby keep the distance between the two fasteners 20 to a minimum.

In this way, the user can operate the control member 50 with the lock core 13 to rotate to control the distance between the two fasteners 20 and adjust the distance between the first point 23 and the second point 24 on the two fasteners 20 , So that this creation can use different distances between the second point 24 and the first point 23 to correspond to the anti-theft keyholes of different sizes.
