Safety device lock

Abstract

The present invention is a security device lock, which comprises a fixing member and at least one clamping hook. The fixing member is arranged in a theft-proof hole of an electronic device. The clamping hook is axially movable relative to the fixing member, and during the movement, the clamping hook moves radially outward along a guide structure of the fixing member to engage the theft-proof hole, and during the movement, the fixing member remains stationary (does not move or rotate). Thus, during the locking process, the theft-proof hole is not pushed and pressed, thereby avoiding the accumulated use from damaging the structure of the theft-proof hole. In addition, the fixing member does not move or rotate during the locking process, so a stable support point can be formed to support the clamping hook, thereby allowing the clamping hook to stably engage the theft-proof hole, and effectively improving the overall tensile strength and the compressive strength in two perpendicular directions, thereby improving the theft-proof effect.

Description

Technical Field

[0001] This invention relates to a security device lock, and more particularly to a security device lock for the burglar vent of a laptop computer. Background Technology

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

[0003] One type of laptop lock in the prior art includes a housing, a push post, two latches, a spring, and a fixing structure. The push post is movable back and forth within the housing and protrudes outward from the housing. The two latches are movable laterally within the housing and protrude outward from the housing. Additionally, the push post has an oblique guide structure on its top and bottom surfaces, and the two latches are respectively located in these two guide structures. The spring is located between the inner wall of the housing and the push post, pushing the push post outward. When the push post compresses the spring and retracts inward into the housing to a certain distance, the fixing structure engages the push post, holding it in that back-and-forth position.

[0004] In use, first insert the push post into the laptop's security hole, ensuring it rests against the bottom of the slot. Then, continue pushing the housing towards the security hole (effectively causing the push post to retract inwards relative to the housing). As the housing continues to move towards the security hole, the two latches move diagonally outwards along the guide structure on the push post, thus engaging the inner walls of the trapezoidal security hole on both sides. When the housing is pushed a certain distance, the fixing structure engages the push post, holding it in that position. In this way, the two latches cannot retract, maintaining the engagement of the security hole.

[0005] When you want to unlock the laptop, the lock will switch to the unlocked state. This will cause the fixing structure to no longer engage with the push post, and the spring will push the shell away from the anti-theft hole, which will then cause the two hooks to retract diagonally along the guide structure to release the engagement.

[0006] However, the aforementioned prior art has two drawbacks: First, each time the device is locked, the push pin must be pressed against the bottom of the anti-theft hole, and then the housing must be pushed forcefully (in order to compress the spring). This is equivalent to squeezing the bottom of the anti-theft hole. The continuous squeezing after long-term and repeated use may damage the structure of the anti-theft hole or even cause the bottom of the hole to crack and be damaged.

[0007] In particular, the security hole is integrally molded into the laptop's casing. Once the security hole is damaged, the entire casing needs to be replaced, which is not only costly but also environmentally unfriendly. In addition, laptops that frequently use the security hole are usually higher-priced laptops. It is unacceptable for users that high-priced laptops are easily damaged under normal use, and replacing the casing of a high-priced laptop can be extremely expensive.

[0008] Secondly, the push post is a component that moves relative to the housing, therefore it is not a stable support point. The latch itself is also a moving component. Therefore, the two moving components pressed together inevitably create an unstable structure, especially since this structure is intended to secure other objects (the burglar slit), making it difficult to securely hold them. Thus, the existing latch technology is insufficient in terms of both tensile strength along the pull-out direction (X-axis) and compressive strength in the two perpendicular directions of the lock itself (Y-axis and Z-axis), making it difficult to effectively achieve the anti-theft effect. Summary of the Invention

[0009] In view of the aforementioned shortcomings and deficiencies of the prior art, the present invention provides a security device lock that does not require squeezing the anti-theft hole during the locking process, thereby avoiding damage to the anti-theft hole.

[0010] To achieve the aforementioned objective, the present invention employs a security lock designed to secure an electronic device having a burglarproof opening. The security lock comprises:

[0011] A shell;

[0012] A fastener is axially inserted into the burglar hole of the electronic device, and the fastener is formed with two guide structures; the fastener protrudes from an opening in the housing;

[0013] Two hooks are axially movable relative to the fixing member. During the axial movement of the two hooks relative to the fixing member, they will move radially outward in opposite directions along the corresponding guide structure of the fixing member to engage the anti-theft hole.

[0014] When the fastener is inserted into the anti-theft hole, during the process of the two hooks moving relative to the fastener and engaging the anti-theft hole, the fastener does not undergo displacement or angular change relative to the housing and the anti-theft hole.

[0015] When the two hooks move toward the anti-theft hole relative to the fixing member, each hook moves along an arc-shaped path relative to the fixing member to engage the anti-theft hole, and a notch in the arc-shaped path faces outward so as to increase the distance between the outer ends of the two hooks when they move toward the anti-theft hole.

[0016] In use, this invention first fixes the device into the burglar hole of the electronic device. Then, the hook moves relative to the fixing member toward the burglar hole. During the movement of the hook, it simultaneously moves radially outward along the guide structure of the fixing member to engage the burglar hole. Throughout this process, the fixing member remains stationary; that is, the fixing member does not undergo displacement or angular change relative to the lock housing and the burglar hole, but rather the hook moves actively.

[0017] In this way, the locking process will not push or squeeze the security hole, thus preventing damage to its structure from accumulated use. Furthermore, the fastener will not move or rotate during locking, forming a stable support point to hold the hook securely in place. This effectively increases the overall tensile strength and compressive strength in both vertical directions, enhancing the security effect and preventing easy prying.

[0018] Furthermore, in the aforementioned safety device lock, each of the guide structures of the fixing member includes at least one abutment portion; when moving relative to the fixing member, each of the hooks abuts against the at least one abutment portion and moves radially outward.

[0019] Furthermore, in the aforementioned safety device lock, when moving relative to the fixing member, each of the hooks radially abuts against the at least one abutting portion and moves radially outward.

[0020] Furthermore, the security device lock further includes a hook seat that connects to the inner end of each hook and is axially movable relative to the fixing member; when each hook moves away from the anti-theft hole relative to the fixing member, the hook seat guides the inner end of the hook to move radially.

[0021] Furthermore, in the aforementioned safety device lock, when the hook seat moves axially relative to the fixing member, the hook seat drives the two hooks to move axially and simultaneously guides the inner end of each hook to move radially.

[0022] Furthermore, in the aforementioned security device lock, when the two hooks move away from the burglar hole relative to the fixing member, the hook seat guides the inner end of each hook to move radially inward.

[0023] Furthermore, in the aforementioned safety device lock, each of the guide structures of the fixing member includes at least one abutment portion; when moving relative to the fixing member, each hook radially abuts against the at least one abutment portion and moves radially outward; each hook has a fulcrum portion protruding radially outward, and when each hook moves arcuately along the at least one abutment portion, the fulcrum portion abuts against the at least one abutment portion to facilitate the arcuate movement of the hook.

[0024] Furthermore, in the aforementioned safety device lock, each of the hooks has a guide portion that protrudes radially inward from its inner end and passes through the hook seat.

[0025] Furthermore, in the aforementioned safety device lock, the hook seat has two hook grooves formed on it, corresponding to the two hooks respectively. Each hook groove has a connected radial movement space and an entrance. The width of the entrance is smaller than the width of the radial movement space, and the guide part of the hook passes through the entrance into the radial movement space.

[0026] Furthermore, in the aforementioned safety device lock, each of the hooks has a guide portion protruding from its inner end toward the hook seat, and the guide portion passes through the hook seat.

[0027] Furthermore, in the aforementioned safety device lock, the hook seat has two hook grooves formed, corresponding to the two hooks respectively, the two hook grooves extend radially, and the guide portion of the two hooks is respectively inserted into the at least one hook groove.

[0040] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means employed by the present invention to achieve its intended purpose.

[0041] Please see Figure 1 , Figure 2 and Figure 4 As shown, the safety device lock of the present invention is used to secure an electronic device 90, the electronic device 90 having an anti-theft hole 91. The safety device lock includes a fixing member 20 and at least one hook 30, preferably two hooks 30, but may also have only one. In addition, the safety device lock may further include a housing 10, a hook seat 40, a lock cylinder 50, and an unlocking member 60.

[0042] The housing 10 has an opening 11 corresponding to the anti-theft hole 91, and the opening 11 is preferably located at one end of the housing 10.

[0043] The fastener 20 is axially inserted into the anti-theft hole 91 of the electronic device 90, and the fastener 20 is formed with at least one guide structure 21. In this embodiment, there are two guide structures 21 to cooperate with two hooks 30.

[0044] Please see Figures 3 to 5 As shown, the hook 30 can move axially relative to the fixing member 20. During the axial movement of the hook 30 relative to the fixing member 20 (in the direction of movement toward the anti-theft hole 91), it will move radially outward along the guide structure 21 of the fixing member 20 to engage the anti-theft hole 91. Furthermore, when the fixing member 20 is inserted into the anti-theft hole 91, during the process of the hook 30 moving relative to the fixing member 20 to engage the anti-theft hole 91, the fixing member 20 remains stationary, that is, the fixing member 20 does not undergo displacement or angular change relative to the housing 10 and the anti-theft hole 91.

[0045] Please see Figure 2 , Figure 4 and Figure 5As shown, the fastener 20 is located at the opening 11 of the housing 10, and preferably is fixed to the housing 10 without moving or rotating relative to the housing 10. However, this is not a limitation and other variations are possible. At least the fastener 20 will not move or rotate relative to the housing 10 during the process of the hook 30 moving relative to the fastener 20 and engaging the anti-theft hole 91.

[0046] In this embodiment, the inner diameter of the opening 11 of the housing 10 is approximately equal to the outer diameter of the housing 10, and the fastener 20 approximately seals the opening 11. However, this is not a limitation. The cross-sectional area of ​​the opening 11 of the housing 10 may be only slightly larger than the portion of the fastener 20 that extends into the anti-theft hole 91, or the cross-sectional area of ​​the opening 11 may correspond to the anti-theft hole 91. In this case, the cross-sectional area of ​​the fastener 20 may also correspond to the anti-theft hole 91.

[0047] Please see Figures 3 to 5 As shown, in this embodiment, each guide structure 21 of the fixing member 20 includes at least one abutment portion 211. When the hook 30 moves relative to the fixing member 20, the hook 30 abuts against the abutment portion 211 and moves radially outward. Preferably, the hook 30 abuts against the abutment portion 211 radially to allow the hook 30 to move radially outward. Furthermore, preferably, each guide structure 21 includes two abutment portions 211, and the two abutment portions 211 are located on opposite radial sides of the hook 30. However, the abutment direction and number of abutment portions 211 are not limited to the above. Additionally, the abutment portion 211 abuts against the hook 30 can be a plane (e.g., ...). Figure 13 , Figure 16 and Figure 19 As shown), but it can also be non-planar, for example, it can have a protruding rib 2111 (as shown). Figure 14 , Figure 17 and Figure 20 As shown), or it has a recessed long groove 2112 (as shown). Figure 15 , Figure 18 and Figure 21 (As shown). Additionally, the guide structure 21 (and the abutment portion 211) can be formed on the outer surface of the fixing member 20 (e.g., Figures 13 to 18 As shown), and when there are two guide structures 21, the two guide structures 21 are located on opposite sides (top surface and bottom surface) of the fixing member 20, but the guide structure 21 (and the abutment part 211) can also be formed inside the fixing member 20 (as shown). Figures 19 to 21 As shown), each guide structure 21 forms a channel, but the movement of the guide hook 30 of the guide structure 21 of the fastener 20 is not limited to the above.

[0048] Please see Figures 3 to 5As shown, when the hook 30 moves toward the anti-theft hole 91 relative to the fixing member 20, the hook 30 moves radially outward, causing the outer end of the hook 30 to protrude from the radial side wall 22 of the fixing member 20, thereby engaging the anti-theft hole 91. When the hook 30 moves away from the anti-theft hole 91, the hook 30 moves radially inward, causing the outer end of the hook 30 to retract inward, and preferably not protrude from the radial side wall 22 of the fixing member 20. However, at this time, the outer end of the hook 30 may still slightly protrude from the radial side wall 22, as long as it can reduce the overall width when relatively unfolded.

[0049] When the hook 30 moves relative to the fixing member 20 toward the anti-theft hole 91, the hook 30 can move in a straight line (oblique direction) or in an arc to engage the anti-theft hole 91.

[0050] Please see Figures 3 to 5 As shown (and) Figures 13 to 15 As shown, in the first embodiment, the hook 30 moves in an arc shape. The guide structure 21 forms an arc-shaped movement trajectory, and a fulcrum 31 protrudes radially outward from the hook 30. When the hook 30 moves arc-shaped along the guide structure 21, the fulcrum 31 abuts against the side wall of the abutment portion 211 to facilitate the arc-shaped movement of the hook 30. However, the construction that facilitates arc-shaped movement is not limited to this; a fulcrum may also protrude from the side wall of the abutment portion 211 to abut against the radially outward side of the hook 30 to facilitate arc-shaped movement.

[0051] Please see Figure 10 and Figure 11 As shown (and) Figures 16 to 21 As shown), in the second embodiment, the hook 30 moves in a straight line, and the guide structure 21 forms a straight movement trajectory.

[0052] Please see Figures 3 to 5 As shown, the hook seat 40 is connected to the inner end of the hook 30, and the hook seat 40 can move axially relative to the fixing member 20. When the hook 30 moves away from the anti-theft hole 91 relative to the fixing member 20, the hook seat 40 guides the inner end of the hook 30 to move radially, thereby facilitating the radial displacement of the hook 30 (whether linear or arc-shaped).

[0053] The hook seat 40 may only have the aforementioned function of assisting the radial displacement of the hook 30, or it may also have the function of driving the hook 30. That is, when the hook seat 40 moves axially relative to the fixed member 20, the hook seat 40 will drive the hook 30 to move axially (through various means such as pushing or pulling) and at the same time guide the inner end of the hook 30 to move radially.

[0054] In the first embodiment, when the hook 30 moves in an arc shape, when the hook 30 moves away from the anti-theft hole 91 relative to the fixing member 20, the hook seat 40 will guide the inner end of the hook 30 to move radially inward, thereby facilitating the inward retraction of the outer end of the hook 30.

[0055] In the first embodiment, the inner end of the hook 30 has a guide portion 32 that protrudes radially inward. The guide portion 32 passes through the hook seat 40, thereby enabling the hook seat 40 to drive the hook 30.

[0056] In the first embodiment, at least one hook groove 41 is formed on the hook seat 40, and preferably there are two hook grooves 41, which are located on opposite sides (top surface and bottom surface) of the hook seat 40 respectively. The two hook grooves 41 correspond to two hooks 30 respectively. Each hook groove 41 has a connected radial movement space 411 and an entrance 412. The width of the entrance 412 is smaller than the width of the radial movement space 411. The guide part 32 of the corresponding hook 30 passes through the entrance 412 into the radial movement space 411, and the guide part 32 can move radially in the radial movement space 411.

[0057] In the second embodiment, please refer to Figures 8 to 10 As shown, the hook groove 41 of the hook seat 40 differs from that of the first embodiment, and the direction in which the guide portion 32 of the hook 30 passes through the hook seat 40 also differs from that of the first embodiment. The two hooks 30 are located on opposite sides (upper and lower sides) of the hook seat 40, and the guide portion 32 protrudes from the inner end of the hook 30 toward the hook seat 40. The guide portion 32 can be a cylinder (e.g., ...). Figure 9 As shown), but the guide part 32 can also be a flat hook 30 integrally bent into shape (as shown). Figures 22 to 24 (As shown). The two hook grooves 41 of the hook seat 40 extend radially, and preferably the two hook grooves 41 are spaced apart from each other, but the two hook grooves 41 can also be formed on the top and bottom surfaces of the hook seat 40 respectively.

[0058] In addition, please see Figures 22 to 24 As shown, the outer end of the hook 30 abuts against the radial side of the anti-theft hole 91, which can be a flat side (e.g., Figure 22 As shown), it can also have a protrusion 33 (as shown). Figure 23 As shown), it can also be recessed with a groove 34 (as shown). Figure 24 (As shown).

[0059] Please see Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, the lock cylinder 50 can be a key lock or a combination lock. The lock cylinder 50 has a spindle 51. When the lock cylinder 50 is in the unlocked state, the spindle 51 can move axially relative to the housing 10 and will normally move toward the burglar hole 91 or the fixing member 20 (preferably through a spindle elastic component 71). One end of the spindle 51 drives (directly or indirectly) the latch 30 to move axially relative to the fixing member 20, and preferably one end of the spindle 51 is connected to the latch seat 40 and drives the latch 30 to move through the latch seat 40.

[0060] The unlocking member 60 is connected to the spindle 51, and the unlocking member 60 allows the spindle 51 to move away from the fixing member 20. Preferably, the unlocking member 60 protrudes from the housing 10 and can be pressed toward the spindle 51, thereby pushing the spindle 51 away from the fixing member 20 via at least one inclined surface 61, and the unlocking member 60 normally moves away from the spindle 51 (preferably via an unlocking elastic component 72). However, this is not a limitation; the unlocking member 60 can also drive the spindle 51 in other ways. Furthermore, when the lock cylinder 50 is in the locked state, the spindle 51 cannot move axially relative to the housing 10, therefore the unlocking member 60 cannot be operated (pressed).

[0061] Please see Figure 4 and Figure 5 As shown, in use, with the lock cylinder 50 in the unlocked state, the unlocking component 60 moves the spindle 51, causing the hook seat 40 to move the two hooks 30 away from the anti-theft hole 91 and thus retract relative to the fixing component 20. This allows the outer ends of the fixing component 20 and the hooks 30 to extend into the anti-theft hole 91. Then, the unlocking component 60 is released, and the spindle elastic component 71 pushes the spindle 51 towards the anti-theft hole 91, which in turn pushes the hooks 30 through the hook seat 40. The hooks 30 then move obliquely in a straight line (second embodiment) or arc-shaped along the guide structure 21 of the fixing component 20 (first embodiment), causing the outer ends of the hooks 30 to protrude from the fixing component 20 and engage in the anti-theft hole 91. Afterwards, when the lock cylinder 50 is locked, the unlocking component 60 can no longer be operated, and the hooks 30 remain engaged in the anti-theft hole 91.

[0062] During the aforementioned locking process, the fixing member 20 remains stationary and does not undergo displacement or angular change relative to the housing 10 and the anti-theft hole 91. Only the hook 30 moves, thereby avoiding damage to the anti-theft hole 91.

[0063] In addition, the fastener 20 does not move or rotate during the locking process, thus forming a stable support point to support the hook 30, thereby allowing the hook 30 to be stably fixed to the anti-theft hole 91, and effectively improving the overall tensile strength and compressive strength in the two vertical directions.

[0064] Furthermore, in the first embodiment of the present invention, the hook 30 is moved in an arc-shaped manner. Compared to the second embodiment, which moves the hook 30 in a straight line, the arc-shaped manner allows for a longer distance to be covered. Moreover, by cooperating with the arc-shaped movement trajectory of the guide structure 21, the stability of the hook 30 is further enhanced, thereby further strengthening its tensile and compressive strength resistance. For details, please refer to the reference... Figure 12 As shown, the test results of the first embodiment (arc-shaped movement) of the present invention are as follows:

[0065] Tensile strength along the pull-out direction D1: Secure the two hooks 30 to the anti-theft hole 91 of an electronic device 90 and fix the electronic device 90. Then, pass a rope through the present invention and perform a tensile test away from the electronic device 90 at a test speed of 10 mm / min. Under these conditions, the tensile strength is greater than 50 kgf.

[0066] Compression resistance along the first radial direction D2: A round bar is pressed down on the present invention along the first radial direction D2 to perform a compression test at a test speed of 10 mm / min. Under these conditions, the compression resistance is greater than 50 kgf.

[0067] Compression resistance along the second radial direction D3: The invention is pushed along the second radial direction D3 by a round bar to perform a side push test at a test speed of 10 mm / min. Under these conditions, the compression resistance is greater than 50 kgf.

[0068] This invention effectively strengthens tensile strength and compressive strength in two vertical directions, thereby improving the anti-theft effect.

[0069] The above description of the present invention is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. 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 invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
