Description

Technical Field

[0001] This utility model relates to an electronic device lock, and more particularly to a multi-stage adjustable laptop lock. Background Technology

[0002] Existing electronic devices, especially portable electronic devices such as laptops, typically have a burglar hole that is used with a specific lock, such as a laptop lock, to secure the laptop in a specific location to prevent theft.

[0003] Existing laptop security holes come in at least three different sizes (widths), and manufacturers have also developed multi-stage adjustable locks that allow users to adjust them to the appropriate level for their laptops.

[0004] Traditional multi-stage adjustable locks require gradual adjustment of the latches (e.g., turning a knob) to insert the two latches into the laptop's security slot, gradually opening them from a closed position to an angle that matches the security slot's opening angle, thus securing them in place. Unlocking also requires gradual operation, gradually closing the latches until they can be withdrawn from the security slot to separate the lock from the laptop. This gradual operation of the latches each time locking and unlocking is quite inconvenient.

[0005] To address this, an existing electronic lock comprises a position adjustment mechanism, a lock assembly, and an unlocking mechanism. The position adjustment mechanism allows the latch to be quickly deployed to secure the burglar hole, while the unlocking mechanism allows the latch to be quickly retracted when the lock is unlocked. However, because these components operate in different directions, the existing electronic lock has a complex structure and suffers from large size and space-consuming characteristics. Utility Model Content

[0006] In view of the aforementioned shortcomings and deficiencies of the prior art, this utility model provides a multi-stage adjustable electronic device lock, which effectively improves the technical problems through a compact structural configuration and makes it easier for users to operate and use.

[0007] To achieve the aforementioned utility model objective, the technical means employed in this utility model is to design an electronic device lock for securing an electronic device, wherein the electronic device has an anti-theft hole, and the electronic device lock comprises:

[0008] A lock comprising a spindle having an extending direction;

[0009] A fastener for insertion into the anti-theft hole of the electronic device, and having a retracted state and multiple unfolded states;

[0010] A position switching component, which abuts against the spindle of the lock along the extending direction and is rotatable relative to the spindle, to switch between multiple positions, each position corresponding to one of the unfolded states of the fixing component, and the position switching component selectively engages the fixing component, causing the fixing component to directly unfold from the retracted state to the unfolded state corresponding to the current position; and

[0011] An operating component is used to rotate the segment switching component to switch segments;

[0012] When the lock is in the locked state, the spindle of the lock fixes the segment switching component to the current segment.

[0013] The advantage of this utility model is that the segment switching component abuts against the lock's spindle along the extension direction of the spindle and can rotate relative to the spindle, which makes it easier to realize the function of directly unfolding the fixing component from the closed state to the unfolded state corresponding to the current segment with a more compact structure. It has the effects of simple structure, small size and no space occupation. Attached Figure Description

[0029] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means adopted by the present invention to achieve its intended purpose.

[0030] See Figure 1 , Figures 4A to 4C The electronic device lock of this utility model is used to secure an electronic device 90, such as a laptop computer, but is not limited thereto; the electronic device 90 has an anti-theft hole, and different electronic devices 90 have anti-theft holes 91A of different shapes / sizes. Figure 4A ), 91B ( Figure 4B ), 91C ( Figure 4C ).

[0031] like Figure 1 , Figure 2 , Figure 9 and 10 As shown, the electronic device lock of this utility model includes a lock 10, a fixing member 20, a level switching member 30, and an operating member 40. Among them, in... Figure 1 and Figure 2 In the first embodiment shown, the lock 10 is a combination lock; while in the case of... Figure 9 and Figure 10 In the second embodiment, the lock 10 is a key lock.

[0032] Figure 2 and Figure 3 The lock 10 shown includes a spindle 11 for performing locking / unlocking functions, the spindle 11 having an extending direction; the retaining member 20 is for insertion into the burglar holes 91A, 91B, 91C of the electronic device 90, and has a retracted state. Figure 7 ) and multiple unfolded states ( Figures 4A to 4C ).

[0033] The segment switching component 30 abuts against the spindle 11 along the extending direction of the spindle 11 and can rotate relative to the spindle 11 to switch between multiple segments. Each segment corresponds to one of the unfolded states of the fixing component 20, and the segment switching component 30 selectively engages the fixing component 20, causing the fixing component 20 to change from a retracted state. Figure 7 ) Directly expand to the expansion state corresponding to the current rank ( Figures 4A to 4C ).

[0034] Specifically, such as Figure 2 and Figure 5 As shown, in the first embodiment, the fixing member 20 has two pivotally connected hooks 21, and the two hooks 21 tend to enter a closed state through an elastic component; the segment switching member 30 is cylindrical and has multiple pairs of opposing abutment surfaces 301, 302, 303, and the spacing between each pair of abutment surfaces 301, 302, 303 is different, thereby forming different segments. When the segment switching member 30 engages the fixing member 20 with one pair of abutment surfaces 301, 302, 303, as... Figures 4A to 4C As shown, the two hooks 21 of the fastener 20 are engaged and abutted by the pair of abutting surfaces 301, 302, and 303, and are relatively movable to unfold to the unfolded state corresponding to that segment, so as to engage with the corresponding anti-theft holes 91A, 91B, and 91C.

[0035] like Figure 2 , Figure 6 and Figure 8 As shown, the operating member 40 is used to rotate the segment switching member 30, thereby driving the segment switching member 30 to rotate relative to the spindle 11 and switch segments, that is, to engage the two hooks 21 of the fixing member 20 with different pairs of abutment surfaces 301, 302, 303.

[0036] Figure 2 and Figure 3 As shown, the lock 10 is a combination lock and has multiple digit wheel assemblies 101. When the numbers on the digit wheel assembly 101 match the set password, the lock 10 is in the unlocked state; conversely, if the numbers on any digit wheel assembly 101 do not match the corresponding number of digits of the password, the lock 10 is in the locked state. Specifically, the digit wheel assembly 101 includes an inner sleeve, and the spindle 11 has a locking part. When the lock 10 is in the locked state, as... Figure 3 As shown, the spindle 11 is secured by the inner sleeve of the character wheel assembly 101, thereby causing the segment switching member 30 to engage with the fixing member 20 at the current segment, and the fixing member 20 to open in the corresponding unfolded state.

[0037] The second embodiment is similar to the first embodiment, with the main differences being as follows: Figure 10 and Figure 11 As shown, lock 10 is a keyed lock, which can be unlocked or locked using a key K. When lock 10 is locked, spindle 11 moves forward ( Figure 11 (on the right side) so that the rank switching component 30 abuts against and engages with the fixing component 20, so that the fixing component 20 opens in the unfolded state corresponding to the current rank.

[0038] By having the position switching component 30 abut against the spindle 11 along the extension direction of the spindle 11 and rotate relative to the spindle 11, it is easy to realize the function of directly unfolding the fixing component 20 from the closed state to the unfolded state corresponding to the current position with a more compact structure. It has the effect of simplified structure, small size and no space occupation, thereby improving the problems of complex structure, large size and space occupation of existing electronic device locks.

[0039] In the first and second embodiments of this utility model, the operating component 40 is located between the lock 10 and the fixing component 20, making it easier for the operating component 40 and the segment switching component 30 located between the lock 10 and the fixing component 20 to move together, making the structure of the electronic device lock of this utility model more streamlined and easier to process and assemble.

[0040] Specifically, see Figure 2 and Figure 4A The electronic device lock of this utility model includes a housing 50, which is provided with at least one segment guide groove 51. The segment switching component 30 and the operating component 40 are linked through at least one connecting part 31. The connecting part 31 can be: as follows Figure 2 In the first embodiment shown, the connecting part 31 is a portion of the segment switching component 30 and is integrally formed; as Figure 10 and Figure 11 In the second embodiment shown, the connecting part 31 is a single component that is assembled between the segment switching component 30 and the operating component 40; or in other embodiments, the connecting part 31 may be integrally formed with the operating component 40.

[0041] like Figure 6 and Figure 8 As shown, the connecting part 31 can move within the segment guide groove 51, allowing the operating member 40 to be clearly limited and positioned during the rotation of the segment switching member 30 to switch segments, and making segment switching more precise within a streamlined overall structure. Furthermore, by housing the spindle 11, segment switching member 30, and other components within the housing 50, and by providing the segment guide groove 51 on the housing 50, machining is facilitated. The connecting part 31 can also be easily assembled, extending into the segment guide groove 51 and connecting the segment switching member 30 and the operating member 40.

[0042] Furthermore, the segment guide groove 51 includes multiple segment recesses 511, each corresponding to one of the segments. When the lock 10 switches from the unlocked state to the locked state, the connecting part 31 moves along a length direction L of the housing 50 and extends into one of the segment recesses 511, causing the segment switching member 30 to unfold the fixing member 20 according to the corresponding segment. The length direction L is parallel to the extension direction of the spindle 11, and the segment switching member 30 abuts against the spindle 11 along this extension direction and rotates relative to the spindle 11. In other words, the axis of rotation of the segment switching member 30 is parallel to the length direction L and is parallel to or coincides with the extension direction.

[0043] like Figures 6 to 8 As shown, when the lock 10 of the first embodiment is unlocked, each wheel assembly 101 allows the spindle 11 to move, thereby allowing the position switching component 30 to disengage from the locking component 20, that is, allowing the position switching component 30 to restore the locking component 20 to the closed state, so that the two hooks 21 of the locking component 20 can close and exit the anti-theft holes 91A, 91B, and 91C.

[0044] like Figure 2 and Figure 7 As shown, the lock 10 also includes a reset assembly 12, which tends to cause the spindle 11 to push the position switch 30 to the position of the engaging retainer 20, as shown. Figure 3 The image shows a compression spring, other elastic components, or repelling magnetic components, etc. For example... Figures 6 to 8 As shown, after the lock 10 is unlocked, the reset assembly 12 keeps the spindle 11 in the position of the position switch 30, and the operating member 40 is configured to move along the length direction L. The user can pull the operating member 40 to disengage the position switch 30 from the locking member 20. Afterwards, the user can rotate the position switch 30 using the operating member 40 to switch positions.

[0045] like Figure 8 As shown, after switching the level, the user only needs to release the hand, and the operating component 40 and the level switching component 30 will automatically reset under the action of the reset component 12, so that the connecting part 31 enters the level recess 511 of the adjusted level, so that the level switching component 30 and the fixing component 20 are engaged again, and the fixing component 20 is opened in the corresponding unfolded state of the adjusted level.

[0046] See Figures 11 to 14 In the second embodiment of this utility model, a disengagement engagement component 33 is provided inside the housing, which is used to abut against and cause the segment switching component 30 to move in the direction of disengaging engagement fixing component 20, and also to cause the connecting part 31 to move in the direction of exiting the current segment recess 511. In the second embodiment, the disengagement engagement component 33 is as follows: Figure 10 The image shows a compression spring, other elastic components, or repulsive magnetic components.

[0047] When the lock 10 is locked, the spindle 11 presses against the position switching component 30 and compresses the disengagement engagement component 33. The key K rotates the spindle 11, completing the engagement and positioning, causing the position switching component 30 to abut against and engage the fixing component 20. The fixing component 20 opens to the unfolded state corresponding to the current position. When the key K unlocks the lock 10, the spindle 11 disengages from the engaged state, allowing the disengagement engagement component 33 to open as if... Figures 12 to 14 The push position switch 30 and spindle 11 extend out of the rear end of the electronic device lock, so that the position switch 30 automatically disengages from the locking member 20. At this time, the user can directly rotate the position switch 30 through the operating member 40 to switch the position. After locking again with the key K, the locking member 20 can be opened in the unfolded state corresponding to the adjusted position.

[0048] Furthermore, such as Figures 11 to 12 As shown, the position switching component 30 is provided with a positioning shaft 32, and the spindle 11 of the lock 10 is sleeved on the positioning shaft 32, which makes the linkage between the spindle 11 and the position switching component 30 more stable and will not cause problems such as mechanism operation failure due to the deviation of the abutment position. Moreover, the sleeve structure of the positioning shaft 32 and the spindle 11 is simple, easy to process and assemble, which can reduce production costs and improve production efficiency, while improving good reliability and reducing the overall size of the electronic device lock and saving space.

[0049] Furthermore, in the first and second embodiments of this utility model, the operating member 40 is annular, sleeved on the housing 50, and covers the at least one segment guide groove 51. In this way, the operating member 40 can be easily engaged and positioned during assembly, and connected to the segment switching member 30 via the connecting part 31, while also shielding the segment guide groove 51 to prevent foreign objects from falling into the segment guide groove 51 and affecting the operation of the mechanism.

[0050] Preferably, the aforementioned connecting portion 31 is engaged with the inner surface of the operating member 40, specifically, as follows: Figure 2 , Figure 4A , Figure 11 and Figure 12 As shown, the inner surface of the operating member 40 is provided with at least one locking recess 41, corresponding to one end of the locking connection part 31, so that when the operating member 40 moves and / or rotates, it drives the segment switching member 30 to move and / or rotate accordingly. Compared with other linkage structure designs, the locking recess 41 on the inner surface of the operating member 40 is easier to process and assemble.

[0051] like Figure 2 and Figure 5 As shown, in the first embodiment, there are two connecting parts 31, locking recesses 41, and segment guide grooves 51, which facilitates the stability of the operating member 40 and the segment switching member 30 when they rotate; however, one or more of these components can also achieve the effect of this utility model.

[0052] See Figure 15 The difference between the third embodiment of this utility model and the previous embodiments is that any two adjacent segment recesses 511 of the segment guide groove 51 are connected by a smooth curved surface S, so that the connecting part 31 can move between the two segment recesses 511 along the smooth curved surface S. Therefore, after the lock 10 is unlocked, when the connecting part 31 has not completely withdrawn from one segment recess 511, it can move to the adjacent segment recess 511 via the smooth curved surface S. In particular, if the electronic device lock of the first embodiment adopts this segment guide groove 51, the user can directly rotate the operating member 40 without pulling it back or with only a slight pull, thereby moving the connecting part 31 to the adjacent segment recess 511 and switching segments, effectively improving the smoothness of use and the efficiency of segment switching.

[0053] In this case, as long as the lock 10 is indeed locked after the position is adjusted, the spindle 11 can still keep the position switching part 30 and the connecting part 31 tightly against the locking and fixing part 20 and the position recess 511, and will not accidentally switch positions while locked.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Anyone skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
