  • the hooking member (23) has a first end in the form of a cross plate (231) confined in the enclosure (1), and an opposite second end in the form of two hooking arms (232) detachably extended into the holes (131) on the insertion section (13).
  • the sleeves (25) each are provided with an axially extended slot (251) corresponding to the teeth (211), two diametrically opposite and externally projected wing portions (252) located at two sides of the slot (251), and an annular groove (253) formed in and around an end of each sleeve (25) to communicate with the axial slot (251).
  • the rotating discs (26) each are provided along an outer circumferential surface with a plurality of sequentially arranged numeral areas (261), such that the numeral areas (261) on the same one rotating disc (26) can be selectively exposed from one of the windows (15) corresponding to that rotating disc (26) by turning the rotating disc (26).
  • the rotating discs (26) each are also provided on an inner circumferential surface with a toothed portion (262), which is able to detachably engage with the wing portions (252) on one corresponding sleeve (25).
  • the push button (3) is movably arranged on at least one lateral side of the enclosure (1).
  • a first end of the push button (3) is a push section (31) outward protruded from the enclosure (1), and an opposite second end of the push button (3) is a driving head (32) interfering with the inclined shoulder portion (222) of the push member (22).
  • Fig. 5 is a perspective view showing the use of the locking device of the present invention to lock a connecting port (41) on a computer case of a computer (4)
  • Figs. 6 and 7 are sectional views showing the locking device of the present invention locked to and detached from the connecting port (41), respectively.
  • the connecting port (41) which can be a USB connecting port
  • the insertion section (13) of the enclosure (1) is directly inserted into the USB connecting port (41) on the computer case of the computer (4).
  • the hooking arms (232) on the hooking member (23) of the locking unit (2) are elastically compressed downward by an inner wall surface of the USB connecting port (41).
  • the insertion section (13) of the enclosure (1) is locked to the USB connecting port (41) on the computer (4), preventing any other external storage device from being plugged in the USB connecting port (41) to access data stored in the computer (4) without authorization.
  • the user can turn the rotating discs (26) of the locking unit (2) via the windows (15), so that the toothed portions (262) in the rotating discs (26) cooperate with the wing portions (252) to rotate the sleeves (25), bringing the annular grooves (253) in an end of the sleeves (25) to rotate outside the teeth (211) of the rod (21) for a correct combination of numerals to show on the numeral areas (261) in the windows (262).
  • the numeral areas (261) on each of the rotating discs (26) are initially set for a predetermined one of the numerals thereon to correspond to one tooth on the toothed portion (262) as well as to the axial slot (251) and the wing portions (252) on the corresponding sleeve (25), when the rotating discs (26) are rotated for the predetermined numerals on the numeral areas (261) to show at the windows (15) in a correct combination, the axial slots (251) on the sleeves (25) would align with the teeth (211) on the rod (21), allowing the line of teeth (211) on the rod (21) to move through the axial slots (251). At this point, the user can easily push the push section (31) of the push button (3) inward.
  • the driving head (32) of the push button (3) interferes with and slides along the inclined shoulder portion (222) to drive the push member (22) forward.
  • the push member (22) is moved toward the fixing seat (14) to compress the elastic member (24) and bring the rod (21) to move forward, so that the engaging portion (221) urges and biases the hooking arms (232) of the hooking member (23) downward, bringing the hooking arms (232) to retract from the retaining holes (411) of the USB connecting port (41) into the holes (131) of the insertion section (13) to unlock the locking device from the USB connecting port (41), permitting the user to remove the insertion section (13) of the enclosure (1) from the USB connection port (41).
  • the user needs only to rotate the rotating discs (26) for a desired set of numerals on the numeral areas (261) to show at the windows (15), and then releases the push button (3), so that the elastic member (24) is elastically restored and pushes the rod (21) backward, bringing the wing portions (252) on the sleeves (25) to engage with the toothed portions (262) in the rotating discs (26) again.
  • a new combination of numerals is set for the locking unit (2).
  • the locking device with changeable combination of numerals by means of the locking unit, the insertion section of the enclosure can be locked to a connecting port on a computer to hinder any unauthorized external storage device from linking with the connecting port. Moreover, the locking device of the present invention allows a user to change the combination of numerals for the locking unit according to actual need. Therefore, the data stored in the computer are protected from unauthorized access. With the above arrangements, the locking device of the present invention effectively overcomes the safety problems in the conventional connecting port on the computer, and is therefore improved and practical for use to meet general users' requirements.
