Description

Technical Field

[0001] This invention relates to a lock. Furthermore, this invention relates to a lock for use in electronic devices. Background Technology

[0002] In modern life, consumer electronics play a vital role. Coupled with today's fast-paced lifestyle and people's need for instant information, portable electronic products have become necessities. However, due to their high unit price and ease of resale, these products are also more susceptible to theft or misappropriation.

[0003] To prevent theft, locks, such as laptop locks, have been designed. These locks connect to the security lock spool of electronic devices via their latches, and the movement of the latches is controlled by a key mechanism to lock / unlock. However, security lock spools come in various sizes, requiring users to purchase / carry locks with corresponding latches, which is not only uneconomical but also inconvenient. Furthermore, the user-friendliness of lock operation could be improved. Utility Model Content

[0004] The purpose of this invention is to provide a lock that can be used with keyholes of different sizes and has better ease of use.

[0005] Another objective of this invention is to provide a lock that is more user-friendly in operation.

[0006] The novel lock comprises a housing, a latch, a drive mechanism, and a lock body. The housing extends along the X-axis and includes opposite front and rear ends. The latch is disposed within the housing and is rotatable relative to the housing; the latch includes a front end portion extending beyond the front end. Part of the drive mechanism is disposed within the housing, and a portion extends from the rear end or between the rear and front ends of the housing. The drive mechanism is rotatable relative to the X-axis, thereby changing the width of the front end portion opening relative to the X-axis. The lock body is disposed on one side of the drive mechanism; when the lock body is locked, it restricts the rotation of the drive mechanism.

[0007] In this embodiment of the invention, the latch includes a rear end extending in the opposite direction to the front end, and the driving device includes a force-applying member and a driving member. The force-applying member includes a force-receiving part extending from the rear end of the housing and a force-applying part disposed within the housing. The force-receiving part is connected to the force-applying part and can rotate relative to the housing. The driving member is disposed within the housing and rotates in conjunction with the force-applying member. The driving member has an inner wall, the distance of which varies circumferentially relative to the X-axis. The rear end is disposed within the driving member and abuts against the inner wall of the driving member. The lock body includes an engaging member movable in a direction perpendicular to the X-axis. When the lock body is locked, one end of the engaging member engages with the driving surface of the driving member to restrict the rotation of the driving device.

[0008] In this embodiment of the invention, the latch includes a rear end extending in the opposite direction to the front end, and the driving device includes a force-applying member and a driving member. The force-applying member includes a force-receiving part extending from the rear end of the housing and a force-applying part disposed within the housing. The force-receiving part is connected to the force-applying part and can rotate relative to the housing. The driving member is disposed within the housing and rotates in conjunction with the force-applying member to move along the X-axis direction on the side of the rear end facing the X-axis, and abuts against the rear end to change the width of the opening of the front end. The lock body includes an engaging member that can move in a direction perpendicular to the X-axis through the force-applying member and the driving member to reach the inner wall of the housing. When the lock body is locked, one end of the engaging member engages with the inner wall of the housing to restrict the rotation of the driving device.

[0009] In this embodiment of the invention, the driving device further includes a displacement limiting member fixed within the housing. The displacement limiting member has an accommodating space extending along the X-axis, and a sidewall thread is provided on the sidewall of the accommodating space. The driving member is disposed in the accommodating space and is a cylinder with a driving member thread on its side that matches the sidewall thread. When the force-applying member rotates, the driving member rotates in conjunction, and through the interaction between the sidewall thread and the driving member thread, the rear end of the driving member moves along the X-axis.

[0010] In this embodiment of the invention, the hook includes a rear end extending in the opposite direction to the front end, and the driving device includes a force-applying member and a driving member. The force-applying member is disposed around the housing between the rear end and the front end, and has an inner wall with a locking portion. The driving member is disposed within the housing, and has a surface and an inner wall. The surface has a locking block that can pass through the housing to enter the locking portion, thereby causing the driving member and the force-applying member to rotate in conjunction. The distance of the inner wall of the driving member relative to the X-axis varies circumferentially, and the rear end is disposed within the driving member and abuts against the inner wall. The lock body includes a locking member movable along the X-axis. When the lock body is locked, one end of the locking member abuts against the end of the driving member away from the hook to restrict the movement of the driving member along the X-axis.

[0011] In this embodiment of the invention, the housing has a hollow portion, which includes a movable groove extending circumferentially relative to the X-axis and a plurality of limiting grooves extending from the movable groove toward the latch along the X-axis. When the lock body is unlocked, the drive block can move in the movable groove and the plurality of limiting grooves; when the lock body is locked, the drive block is located in one of the plurality of limiting grooves.

[0012] In this embodiment of the invention, the hook includes a rear end extending in the opposite direction to the front end, and the driving device includes a force-applying member and a driving member. The force-applying member includes a force-receiving part extending from the rear end of the housing and a force-applying part disposed within the housing. The force-receiving part and the force-applying part are connected and can rotate relative to the housing. The side of the force-applying member facing the hook has a stepped surface. The driving member is disposed within the housing and has an inner wall. The distance of the inner wall of the driving member relative to the X-axis gradually increases as it approaches the hook, and the inner wall of the driving member abuts against the rear end. The other side of the driving member relative to the hook abuts against the stepped surface. Rotation of the force-applying member causes the driving member to move along the X-axis, thereby changing the width of the opening of the front end. The lock body includes an engaging member that can move in a direction perpendicular to the X-axis. When the lock body is locked, one end of the engaging member engages with the force-applying surface of the force-applying member to restrict the rotation of the driving device.

[0013] In this embodiment of the invention, the hook includes a rear end extending in the opposite direction to the front end, and the driving device includes a force-applying member, a transmission member, and a driving member. The force-applying member includes a force-receiving part extending from the rear end of the housing and a force-applying part disposed within the housing. The force-receiving part is connected to the force-applying part and can rotate relative to the housing. The transmission member is disposed within the housing, can rotate in conjunction with the force-applying member, and can move along the X-axis. The driving member is disposed within the housing and has an inner wall. The distance of the inner wall of the driving member relative to the X-axis gradually increases as it approaches the hook, and the inner wall of the driving member abuts against the rear end. The other side of the driving member relative to the hook abuts against the transmission member. Rotation of the force-applying member causes the transmission member to move along the X-axis, and drives the driving member to move along the X-axis, thereby changing the opening width of the front end. The lock body includes an engaging member that can move in a direction perpendicular to the X-axis. When the lock body is locked, one end of the engaging member engages with the force-applying surface of the force-applying member to restrict the rotation of the driving device.

[0014] In this embodiment of the invention, the driving device further includes a displacement limiting member fixed within the housing. The displacement limiting member has an accommodating space extending along the X-axis, and the sidewall of the accommodating space is provided with a sidewall thread. A transmission member is disposed within the accommodating space, and the transmission member is a cylinder with a transmission member thread on its side that matches the sidewall thread. When the force-applying member rotates, the transmission member rotates in conjunction, and through the interaction between the sidewall thread and the transmission member thread, the transmission member moves along the X-axis direction.

[0015] In this embodiment of the invention, the lock body is a key lock, and the engaging component includes a protrusion.

[0016] In this embodiment of the invention, the lock body is a combination lock, and the engaging component includes a lock shaft. Attached Figure Description

[0198] This novel lock is for use with electronic devices, providing a connection to the keyhole of the electronic device. The electronic device is preferably portable, such as, but not limited to, laptops, tablets, mobile phones, e-readers, digital photo frames, GPS navigators, mobile network devices, personal digital assistants, portable digital music players, electronic dictionaries, etc.

[0199] like Figures 1A to 1EIn the illustrated embodiment, the lock 8001 of this invention includes a housing 1100, a latch 1400, a drive unit 1200, and a lock body 1300. The housing 1100 extends along the X-axis and includes opposite front ends 1101 and rear ends 1102. The latch 1400 is disposed within the housing 1100 and is rotatable relative to the housing 1100. Preferably, the latches 1400 are arranged in pairs, each including a front end portion 1410 extending out of the front end portion 1101. A portion of the drive unit 1200 is disposed within the housing 1100, and a portion extends out of the housing 1100 from the rear end portion 1102. The drive unit 1200 is rotatable relative to the X-axis to change the width of the front end portion 1410 opening relative to the X-axis. The lock body 1300 is disposed on one side of the drive unit 1200, and when the lock body 1300 is locked, it restricts the rotation of the drive unit 1200.

[0200] Furthermore, such as Figure 1D and Figure 1E In the illustrated embodiment, the hook 1400 includes a rear end portion 1420 extending in the opposite direction to the front end portion 1410, and the driving device 1200 includes a force-applying member 1210 and a driving member 1220. The force-applying member 1210 includes a force-receiving portion 1211 extending from the rear end portion 1102 of the housing 1100 and a force-applying portion 1212 disposed within the housing 1100. The force-receiving portion 1211 and the force-applying portion 1212 are connected by, for example, a rod 1213 and are rotatable relative to the housing 1100. The driving member 1220 is disposed within the housing 1100 and rotates in conjunction with the force-applying member 1210. Preferably, the driving member 1220 is cylindrical and has an inner wall 1221. The distance of the inner wall 1221 relative to the X-axis varies along the circumferential direction, and the rear end portion 1420 is disposed within the driving member 1220 and abuts against the inner wall 1221. The lock body 1300 includes an engaging member 1310 movable in a direction perpendicular to the X-axis. When the lock body 1300 is locked, one end 1311 of the engaging member 1310 engages with the driving surface 1222 of the driving member 1220 to restrict the rotation of the driving device 1200. In this embodiment, the lock body 1300 is a combination lock, and the engaging member 1310 includes a lock shaft.

[0201] More specifically, the force-applying member 1210 can overcome the elastic force generated by the compression of the elastic device 1214, such as a spring, causing the force-applying part 1212 to insert into the driving member 1220 and engage with the limiting part 1224, thereby causing the driving member 1220 and the force-applying member 1210 to rotate together. The engaging member 1310 can use the elastic force of the elastic device 1320, such as a spring, to make one end 1311 abut against the surface 1222 of the driving member. When the lock body 1300 is locked (i.e., the lock 8001 is in the locked state), the displacement of the engaging member 1310 is restricted because the rotation of the driving member 1220 is restricted because one end 1311 engages with the surface 1222 of the driving member. When the lock body 1300 is unlocked (i.e., the lock 8001 is in the unlocked state), the engaging member 1310 can move, the driving member 1220 is not restricted by it, and the force-applying member 1210 inserted into the driving member 1220 can rotate to drive the driving member 1220 to rotate, so that the rear end 1420 that abuts against the inner wall 1221 of the driving member moves, thereby causing the hook 1400 to rotate to change the opening range of the front end 1410 relative to the X-axis.

[0202] The following is passed Figures 1F to 1N The illustrated embodiment explains the operation of internal components of the lock 8001. For clarity, components such as the housing 1100 are shown... Figures 1F to 1N Not shown.

[0203] like Figure 1F In the embodiment shown, the force-applying part 1212 is not inserted into the limiting part 1224 of the driving member 1220. Then, as... Figure 1G In the embodiment shown, the force-applying member 1210 can move along the X-axis due to the force-receiving part 1211 being subjected to an external force applied by the user, causing the force-applying part 1212 to insert into the limiting part 1224 of the driving member 1220. Specifically, by designing mutually adaptable cross-sections on the force-applying part 1212 and the limiting part 1224, the force-applying part 1212 can engage with the limiting part 1224 after being inserted into the driving member 1220.

[0204] Next, as Figure 1HIn the illustrated embodiment, when the lock body 1300 is unlocked (e.g., by rotating the dial of the lock body 1300 to the unlock position), the engaging member 1310 can move along the Z-axis, allowing the end 1311 to disengage from the driving member engaging portion 1223 located on the driving member surface 1222, i.e., the driving member engaging portion 1223 can disengage from the end 1311. The driving member engaging portion 1223 may be a protrusion annularly disposed on the driving member surface 1222, and the end 1311 may have a groove capable of engaging with the protrusion. Therefore, the rotation of the drive member 1220 is not restricted. When the force-applying member 1210 rotates in a direction parallel to the YZ plane due to the external force applied by the user to the force-receiving part 1211, the force-applying member 1210 inserted into the drive member 1220 can rotate to drive the drive member 1220 to rotate, causing the rear end 1420 that abuts against the inner wall 1221 of the drive member to move, thereby causing the hook 1400 to rotate to change the opening amplitude of the front end 1410 relative to the X-axis. Among them, the X-axis, Y-axis and Z-axis are orthogonal.

[0205] like Figure 1I In the embodiment shown, when the force-applying member 1210 rotates and drives the driving member 1220 to rotate to the desired position, the engaging part 1223 of the driving member engages with the end 1311. If the lock body 1300 is locked at this time (for example, rotating the dial of the lock body 1300 to the non-unlocked position), the engaging member 1310 can be restricted from moving along the Z-axis, thereby restricting the rotation of the driving member 1220, so that the front end 1410 has the required opening range, for example, slightly wider than the keyhole width of the electronic device, and is engaged and fixed in the keyhole.

[0206] Further explanation of the relationship between the rotation of the drive component 1220 and the opening amplitude of the front end 1410. For example... Figures 1J to 1L In the embodiment shown, the drive member 1220 has an inner wall 1221, the distance of which relative to the X-axis varies along the circumferential direction. On the other hand, as... Figure 1M and Figure 1N In the embodiment shown, the rear end portion 1420 is disposed in the drive member 1220 and abuts against the inner wall 1221 of the drive member. Therefore, by rotating the drive member 1220, the rear end portion 1420 abutting against the inner wall 1221 of the drive member can be moved, thereby causing the hook 1400 to rotate to change the opening range of the front end portion 1410 relative to the X-axis.

[0207] Based on the above, the novel lock 8001 can be used with keyholes of different sizes, offering superior ease of use. Furthermore, the aforementioned operation can be achieved by the user rotating the force-applying component 1210, making it more user-friendly. On the other hand, in different embodiments, the housing, latch, drive mechanism, and lock body included in the novel lock can be configured differently according to requirements.

[0208] like Figures 2A to 2EIn the illustrated embodiment, the lock 8002 of this invention includes a housing 2100, a latch 2400, a drive mechanism 2200, and a lock body 2300. The housing 2100 extends along the X-axis and includes opposite front ends 2101 and rear ends 2102. The latch 2400 is disposed within the housing 2100 and is rotatable relative to the housing 2100. Preferably, the latches 2400 are arranged in pairs, each including a front end portion 2410 extending out of the front end portion 2101. A portion of the drive mechanism 2200 is disposed within the housing 2100, and a portion extends out of the housing 2100 from the rear end portion 2102. The drive mechanism 2200 is rotatable relative to the X-axis to change the width of the front end portion 2410 opening relative to the X-axis. The lock body 2300 is disposed on one side of the drive mechanism 2200, and when the lock body 2300 is locked, it restricts the rotation of the drive mechanism 2200.

[0209] Furthermore, such as Figures 2C to 2E In the illustrated embodiment, the hook 2400 includes a rear end portion 2420 extending in the opposite direction to the front end portion 2410, and the driving device 2200 includes a force-applying member 2210 and a driving member 2220. The force-applying member 2210 includes a force-receiving portion 2211 extending out of the housing 2100 from the rear end portion 2102 and a force-applying portion 2212 disposed within the housing 2100. The force-receiving portion 2211 is connected to the force-applying portion 2212 and can rotate relative to the housing 2100. The driving member 2220 is disposed within the housing 2100, and is designed by, for example, providing mutually adaptable cross-sections 2212A and 2220A on the inner surface of the force-applying portion 2212 and the outer surface of the driving member 2220 respectively (see [reference]). Figure 2C1 The driving member 2220 can rotate in conjunction with the force-applying member 2210 and move along the X-axis direction on the side of the rear end 2420 facing the X-axis, and abut against the rear end 2420 to change the opening width of the front end 2410. The lock body 2300 includes a locking member 2310, which can move in a direction perpendicular to the X-axis through the hole 2214 of the force-applying member 2210 and the hole 2224 of the driving member 2220 to reach the inner wall 2103 of the housing 2100. When the lock body 2300 is locked, one end of the locking member 2310 engages with the inner wall 2103 of the housing to restrict the rotation of the driving device 2200. The inner wall 2103 of the housing may be further provided with a groove 2104 for more secure engagement with the locking member 2310. In this embodiment, the lock body 2300 is a key lock, and the locking member 2310 includes a protrusion.

[0210] More specifically, such as Figures 2F to 2IIn the illustrated embodiment, the drive device 2200 further includes a displacement limiting member 2230 fixed within the housing 2100. The displacement limiting member 2230 has an accommodating space 2231 extending along the X-axis, and a sidewall thread 2232 is provided on the sidewall of the accommodating space 2231. The drive member 2220 is disposed in the accommodating space 2231, and the drive member 2220 is preferably a cylinder with a drive member thread 2222 on its side that matches the sidewall thread 2232. Figure 2F In the embodiment shown, when the lock body 2300 is locked, one end of the engaging member 2310 passes through the hole 2214 of the force-applying member 2210 and the hole 2224 of the driving member 2220 and engages with the groove 2104 to restrict the rotation of the driving device 2200. Figure 2G In the embodiment shown, when the lock body 2300 is unlocked (e.g., using a key), the engaging member 2310 disengages from the hole 2214 of the force-applying member 2210 and the hole 2224 of the driving member 2220, thereby releasing the restriction on the rotation of the driving device 2200.

[0211] Next, as Figure 2H In the illustrated embodiment, when the force-applying member 2210 rotates in a direction parallel to the YZ plane due to the external force applied by the user to the force-receiving part 2211, the driving member 2220 rotates in conjunction. Through the interaction between the sidewall thread 2232 and the driving member thread 2222, one end 2221 of the driving member 2220 towards the rear end 2420 moves along the X-axis. Since end 2221 abuts against the rear end 2420, the movement of the driving member 2220 along the X-axis changes the width of the rear end 2420 relative to the X-axis, thereby changing the width of the front end 2410 relative to the X-axis. Then, as... Figure 2I In the embodiment shown, if the lock body 2300 is locked (e.g., using a key), one end of the engaging member 2310 engages with the groove 2104, restricting the rotation of the drive device 2200, so that the front end 2410 has the required opening range, for example, slightly wider than the keyhole width of the electronic device, and is engaged and fixed in the keyhole.

[0212] like Figures 3A to 3CIn another embodiment shown, the lock 8003 of this invention includes a housing 3100, a latch 3400, a drive device 3200, and a lock body 3300. The housing 3100 extends along the X-axis and includes opposite front ends 3101 and rear ends 3102. The latch 3400 is disposed within the housing 3100 and is rotatable relative to the housing 3100. Preferably, the latches 3400 are arranged in pairs, each including a front end portion 3410 extending partially from the front end portion 3101. A portion of the drive device 3200 is disposed within the housing 3100, and a portion extends out of the housing 3100 between the rear end portion 3102 and the front end portion 3101. The drive device 3200 is rotatable relative to the X-axis to change the width of the front end portion 3410 opening relative to the X-axis. The lock body 3300 is disposed on one side of the drive device 3200, and when the lock body 3300 is locked, it restricts the rotation of the drive device 3200.

[0213] Furthermore, such as Figure 3C In the illustrated embodiment, the hook 3400 includes a rear end portion 3420 extending in the opposite direction to the front end portion 3410, and the drive device 3200 includes a force-applying member 3210 and a drive member 3220. The force-applying member 3210 is disposed around the housing 3100 between the rear end portion 3102 and the front end portion 3101, and the force-applying member 3210 has a force-applying member inner wall 3211, and the force-applying member inner wall 3211 has a force-applying member engaging portion 3212. A driving member 3220 is disposed within a housing 3100. The driving member 3220 has a driving member surface 3221 and a driving member inner wall 3222. The driving member surface 3221 has a driving member locking block 3221A, which can pass through the housing 3100 to enter the force-applying member engaging portion 3212, so that the driving member 3220 and the force-applying member 3210 rotate in conjunction. The distance of the driving member inner wall 3222 relative to the X-axis varies in the circumferential direction. The rear end portion 3420 is disposed in the driving member 3220 and abuts against the driving member inner wall 3222. The lock body 3300 includes an engaging member 3310 that can move along the X-axis. When the lock body 3300 is locked, one end of the engaging member 3310 abuts against the end of the driving member 3220 away from the hook 3400 to restrict the movement of the driving member 3220 along the X-axis.

[0214] More specifically, such as Figure 3C In the illustrated embodiment, the housing 3100 has a cutout portion 3110, which includes a movable groove 3111 extending circumferentially relative to the X-axis and a plurality of limiting grooves 3112 extending from the movable groove toward the latch 3400 along the X-axis. When the lock body 3300 is unlocked, the drive member 3220 is movable, allowing the drive member latch block 3221A to move within the movable groove 3111 and the plurality of limiting grooves 3112. When the lock body 3300 is locked, the drive member latch block 3221A is located in one of the plurality of limiting grooves 3112.

[0215] The following is passed Figures 3D to 3I The illustrated embodiment explains the operation of lock 8003. For example... Figure 3D In the illustrated embodiment, when the lock body 3300 is locked (e.g., the dial of the lock body 3300 is rotated to the non-unlocked position), the movement of the drive member 3220 along the X-axis is restricted, thereby restricting the drive member locking block 3221A from moving away from the limiting groove 3112, further preventing the force-applying member 3210, which is engaged with the drive member 3220, from rotating. Figure 3E In the embodiment shown, when the lock body 3300 is unlocked (e.g., the dial of the lock body 3300 is rotated to the unlock position), the restriction on the movement of the drive member 3220 along the X-axis is released, allowing the drive member locking block 3221A to move away from the limiting groove 3112, thus allowing the force-applying member 3210, which is engaged with the drive member 3220, to rotate.

[0216] Next, as Figure 3F In the illustrated embodiment, when the force-applying member 3210 rotates in a direction parallel to the YZ plane due to the external force applied by the user, it drives the driving member 3220 to rotate, causing the driving member locking block 3221A to move to a position opposite to another limiting groove 3112'. Here, the X-axis, Y-axis, and Z-axis are orthogonal. Then, as... Figure 3G In the illustrated embodiment, the driving block 3221A is moved into the limiting groove 3112' by the elastic force of an elastic device such as a spring. On the other hand, as... Figure 3H and Figure 3I In the embodiment shown, since the distance between the inner wall 3222 of the drive member and the X-axis varies along the circumferential direction, and the rear end 3420 is disposed in the drive member 3220 and abuts against the inner wall 3222 of the drive member, when the drive member 3220 rotates, the latch 3400 can rotate to change the opening of the front end 3410 relative to the X-axis to meet the requirements, for example, slightly wider than the width of the keyhole of the electronic device, and engage and fix it in the keyhole.

[0217] like Figures 4A to 4D In another embodiment shown, the lock 8004 of this invention includes a housing 4100, a latch 4400, a drive mechanism 4200, and a lock body 4300. The housing 4100 extends along the X-axis and includes opposite front ends 4101 and rear ends 4102. The latch 4400 is disposed within the housing 4100 and is rotatable relative to the housing 4100. Preferably, the latches 4400 are arranged in pairs, each including a front end 4410 that partially extends out of the front end 4101. A portion of the drive mechanism 4200 is disposed within the housing 4100, and a portion extends out of the housing 4100 between the rear end 4102 and the front end 4101. The drive mechanism 4200 is rotatable relative to the X-axis to change the width of the opening of the front end 4410 relative to the X-axis. The lock body 4300 is disposed on one side of the drive mechanism 4200, and when the lock body 4300 is locked, it restricts the rotation of the drive mechanism 4200.

[0218] Furthermore, such as Figure 4C and Figure 4D In the illustrated embodiment, the hook 4400 includes a rear end portion 4420 extending in the opposite direction to the front end portion 4410, and the driving device 4200 includes a force-applying member 4210 and a driving member 4220. The force-applying member 4210 is disposed around the housing 4100 between the rear end portion 4102 and the front end portion 4101, and has an inner wall 4211 with a force-applying engagement portion 4212. The driving member 4220 is disposed within the housing 4100, and has a driving surface 4221 and an inner wall 4222. The driving surface 4221 has a driving block 4221A, which can pass through the housing 4100 to enter the force-applying engagement portion 4212, so that the driving member 4220 and the force-applying member 4210 rotate in conjunction. The distance between the inner wall 4222 of the drive member and the X-axis varies circumferentially, and the rear end 4420 is disposed in the drive member 4220 and abuts against the inner wall 4222 of the drive member. The lock body 4300 includes a locking member 4310 that can move along the X-axis. When the lock body 4300 is locked, one end of the locking member 4310 abuts against the end of the drive member 4220 away from the latch 4400 to restrict the movement of the drive member 4220 along the X-axis.

[0219] More specifically, such as Figure 4C and Figure 4D In the illustrated embodiment, the housing 4100 has a cutout portion 4110, which includes a movable groove 4111 extending circumferentially relative to the X-axis and a plurality of limiting grooves 4112 extending from the movable groove toward the latch 4400 along the X-axis. When the lock body 4300 is unlocked, the drive member 4220 is movable, allowing the drive member locking block 4221A to move within the movable groove 4111 and the plurality of limiting grooves 4112. When the lock body 4300 is locked, the drive member locking block 4221A is located in one of the plurality of limiting grooves 4112.

[0220] The following is passed Figures 4E to 4I The illustrated embodiment explains the operation of lock 8004. For example... Figure 4E In the illustrated embodiment, when the lock body 4300 is locked (e.g., locked with a key), the movement of the drive member 4220 along the X-axis is restricted, thereby restricting the drive member locking block 4221A from moving away from the limiting groove 4112 (see [link]). Figure 4C This further prevents the force-applying component 4210, which is engaged with the driving component 4220, from rotating. For example... Figure 4F In the embodiment shown, when the lock body 4300 is unlocked (e.g., using a key to unlock), the restriction on the movement of the drive member 4220 along the X-axis is released, and the drive member 4220 can move through the elastic member 4230 (see...). Figure 4DThe elastic force moves along the X-axis away from the hook 4400, allowing the drive block 4221A to move away from the limiting groove 4112, thus allowing the force-applying member 4210, which is engaged with the drive member 4220, to rotate.

[0221] Next, as Figure 4G In the illustrated embodiment, when the force-applying member 4210 rotates relative to the X-axis due to an external force applied by the user, it drives the driving member 4220 to rotate, causing the driving member locking block 4221A to move to another limiting groove 4112' (see...). Figure 4C The relative positions of the axes. The X, Y, and Z axes are orthogonal. Then, as... Figure 4H In the illustrated embodiment, the user can apply force to the engaging member 4310 (see [reference]). Figure 4D Overcoming the elastic force of the elastic element 4230, it pushes the driving element 4210, which abuts against it, to move along the X-axis, causing the driving element locking block 4221A to move into the limiting groove 4112'. Since the rear end 4420 is located in the driving element 4220 and abuts against the inner wall 4222 of the driving element, and the inner wall 4222 of the driving element... Figure 4I As shown, the distance relative to the X-axis varies along the circumferential direction. Therefore, when the drive member 4220 rotates, the latch 4400 can rotate to change the opening of the front end 4410 relative to the X-axis to meet the requirements, such as being slightly wider than the width of the keyhole of the electronic device, and thus engaging and fixing it to the keyhole.

[0222] like Figure 5A and Figure 5B In another embodiment shown, the lock 8005 of this invention includes a housing 5100, a latch 5400, a drive mechanism 5200, and a lock body 5300. The housing 5100 extends along the X-axis and includes opposing front ends 5101 and rear ends 5102. The latch 5400 is disposed within the housing 5100 and is rotatable relative to the housing 5100. Preferably, the latches 5400 are arranged in pairs, each including a front end 5410 that partially extends out of the front end 5101. A portion of the drive mechanism 5200 is disposed within the housing 5100, and a portion extends out of the housing 5100 from the rear end 5102. The drive mechanism 5200 is rotatable relative to the X-axis to change the width of the front end 5410 opening relative to the X-axis. The lock body 5300 is disposed on one side of the drive mechanism 5200, and when the lock body 5300 is locked, it restricts the rotation of the drive mechanism 5200.

[0223] Furthermore, such as Figure 5BIn the illustrated embodiment, the hook 5400 includes a rear end portion 5420 extending in the opposite direction to the front end portion 5410, and the drive device 5200 includes a force-applying member 5210 and a drive member 5220. The force-applying member 5210 includes a force-receiving portion 5211 extending out of the housing 5100 from the rear end portion 5102 and a force-applying portion 5212 disposed within the housing 5100. The force-receiving portion 5211 is connected to the force-applying portion 5212 and can rotate relative to the housing 5100. The side of the force-applying member 5210 facing the hook 5400 has a step surface 5213. The drive member 5220 is disposed within the housing 5100 and has a drive member inner wall 5221. The distance of the drive member inner wall 5221 relative to the X-axis gradually increases as it approaches the hook 5400, and the drive member inner wall 5221 abuts against the rear end portion 5420. The drive member 5220, on the other side relative to the latch 5400, indirectly abuts against the step surface 5213 via the intermediate member 5230. The force-applying member 5210 rotates, causing the drive member 5220 to move along the X-axis, thus changing the opening width of the front end 5410. The lock body 5300 includes an engaging member 5310 movable in a direction perpendicular to the X-axis. When the lock body 5300 is locked, one end of the engaging member 5310 engages with the force-applying member surface 5214 of the force-applying member 5210 to restrict the rotation of the drive device 5200. In this embodiment, the lock body 5300 is a combination lock, and the engaging member 5310 includes a lock shaft.

[0224] More specifically, such as Figure 5C and Figure 5D In the illustrated embodiment, the force-applying member 5210 can rotate relative to the X-axis through the force-receiving part 5211, causing the step surface 5213 to rotate as well. Due to its indirect contact with the step surface 5213, the driving member 5220 moves along the X-axis as the step surface 5213 rotates, thus approaching or moving away from the latch 5400. When the lock body 5300 is locked (i.e., the lock 8005 is in the locked state), the displacement of the engaging member 5310 is restricted. If one end 5311 engages with the surface 5214 of the force-applying member, the rotation of the force-applying member 5210 is restricted. When the lock body 5300 is unlocked (i.e., the lock 8005 is in the unlocked state), the engaging member 5310 can move so that one end 5311 is not engaged with the surface 5214 of the force-applying member, and the force-applying member 5210 can rotate, causing the step surface 5213 to rotate together, thereby driving the driving member 5220 to move along the X-axis. Thus, as... Figure 5E and Figure 5F The embodiment shown can further move the rear end portion 5420 that abuts against the inner wall 5221 of the drive member, thereby rotating the hook 5400 to change the extent of the opening of the front end portion 5410 relative to the X-axis.

[0225] like Figure 6A and Figure 6BIn another embodiment shown, the lock 8006 of this invention includes a housing 6100, a latch 6400, a drive unit 6200, and a lock body 6300. The housing 6100 extends along the X-axis and includes opposite front ends 6101 and rear ends 6102. The latch 6400 is disposed within the housing 6100 and is rotatable relative to the housing 6100. Preferably, the latches 6400 are arranged in pairs, each including a front end 6410 that partially extends out of the front end 6101. A portion of the drive unit 6200 is disposed within the housing 6100, and a portion extends out of the housing 6100 from the rear end 6102. The drive unit 6200 is rotatable relative to the X-axis to change the width of the front end 6410 opening relative to the X-axis. The lock body 6300 is disposed on one side of the drive unit 6200, and when the lock body 6300 is locked, it restricts the rotation of the drive unit 6200.

[0226] Furthermore, such as Figure 6B In the illustrated embodiment, the hook 6400 includes a rear end portion 6420 extending in the opposite direction to the front end portion 6410, and the drive device 6200 includes a force-applying member 6210 and a drive member 6220. The force-applying member 6210 includes a force-receiving portion 6211 extending out of the housing 6100 from the rear end portion 6102 and a force-applying portion 6212 disposed within the housing 6100. The force-receiving portion 6211 is connected to the force-applying portion 6212 and can rotate relative to the housing 6100. The side of the force-applying member 6210 facing the hook 6400 has a step surface 6213. The drive member 6220 is disposed within the housing 6100 and has a drive member inner wall 6221. The distance of the drive member inner wall 6221 relative to the X-axis gradually increases as it approaches the hook 6400, and the drive member inner wall 6221 abuts against the rear end portion 6420. The driving member 6220, on the other side relative to the latch 6400, indirectly abuts against the step surface 6213 via the intermediate member 6230. The force-applying member 6210 rotates, causing the driving member 6220 to move along the X-axis, thus changing the opening width of the front end 6410. The lock body 6300 includes an engaging member 6310 movable in a direction perpendicular to the X-axis. When the lock body 6300 is locked, one end of the engaging member 6310 engages with the force-applying member surface 6214 of the force-applying member 6210 to restrict the rotation of the driving device 6200. In this embodiment, the lock body 6300 is a key lock, and the engaging member 6310 includes a protrusion.

[0227] More specifically, such as Figure 6C and Figure 6DIn the illustrated embodiment, the force-applying member 6210 can rotate relative to the X-axis through the force-receiving part 6211, causing the step surface 6213 to rotate as well. Due to its indirect contact with the step surface 6213, the driving member 6220 moves along the X-axis as the step surface 6213 rotates, thus approaching or moving away from the latch 6400. When the lock body 6300 is locked (i.e., the lock 8006 is in the locked state), the displacement of the engaging member 6310 is restricted. If one end 6311 engages with the surface 6214 of the force-applying member, the rotation of the force-applying member 6210 is restricted. When the lock body 6300 is unlocked (i.e., the lock 8006 is in the unlocked state), the engaging member 6310 can move so that one end 6311 is not engaged with the surface 6214 of the force-applying member, and the force-applying member 6210 can rotate, causing the step surface 6213 to rotate together, thereby driving the driving member 6220 to move along the X-axis. Thus, as... Figure 6E and Figure 6F The embodiment shown can further move the rear end 6420 that abuts against the inner wall 6221 of the drive member, thereby rotating the hook 6400 to change the extent of the opening of the front end 6410 relative to the X-axis.

[0228] like Figure 7A and Figure 7B In another embodiment shown, the lock 8007 of this invention includes a housing 7100, a latch 7400, a drive mechanism 7200, and a lock body 7300. The housing 7100 extends along the X-axis and includes opposing front ends 7101 and rear ends 7102. The latch 7400 is disposed within the housing 7100 and is rotatable relative to the housing 7100. Preferably, the latches 7400 are arranged in pairs, each including a front end 7410 that partially extends out of the front end 7101. A portion of the drive mechanism 7200 is disposed within the housing 7100, and a portion extends out of the housing 7100 from the rear end 7102. The drive mechanism 7200 is rotatable relative to the X-axis to change the width of the front end 7410 opening relative to the X-axis. The lock body 7300 is disposed on one side of the drive mechanism 7200, and when the lock body 7300 is locked, it restricts the rotation of the drive mechanism 7200.

[0229] Furthermore, such as Figure 7BIn the illustrated embodiment, the hook 7400 includes a rear end portion 7420 extending in the opposite direction to the front end portion 7410. The drive device 7200 includes a force-applying member 7210, a transmission member 7230, and a drive member 7220. The force-applying member 7210 includes a force-receiving portion 7211 extending from the rear end portion 7102 of the housing 7100 and a force-applying portion 7212 disposed within the housing 7100. The force-receiving portion 7211 is connected to the force-applying portion 7212 and can rotate relative to the housing 7100. The transmission member 7230 is disposed within the housing 7100, can rotate in conjunction with the force-applying member 7210, and can move along the X-axis. The drive member 7220 is disposed within the housing 7100 and has a drive member inner wall 7221. The distance of the drive member inner wall 7221 relative to the X-axis gradually increases as it approaches the hook 7400, and the drive member inner wall 7221 abuts against the rear end portion 7420. The driving member 7220 abuts against the transmission member 7230 on the other side relative to the latch 7400. The force-applying member 7210 rotates, causing the transmission member 7230 to move along the X-axis, and driving the driving member 7220 to move along the X-axis, thereby changing the opening width of the front end 7410. The lock body 7300 includes a locking member 7310 that can move in a direction perpendicular to the X-axis. When the lock body 7300 is locked, one end 7311 of the locking member 7310 engages with the force-applying member surface 7213 of the force-applying member 7210 to restrict the rotation of the driving device 7200.

[0230] More specifically, the drive device 7200 further includes a displacement limiting member 7240 fixed within the housing 7100. The displacement limiting member 7240 has an accommodating space 7241 extending along the X-axis, and a sidewall thread 7242 is provided on the sidewall of the accommodating space 7241. A transmission member 7230 is disposed within the accommodating space 7241. Preferably, the transmission member 7230 is a cylinder with a transmission member thread 7231 on its side that matches the sidewall thread 7242. One end facing the force-applying member 7210 can be inserted into the force-applying member 7210, and its shape creates interference in the rotational direction relative to the X-axis. Accordingly, when the force-applying member 7210 rotates, the transmission member 7230 rotates in conjunction, and through the interaction between the sidewall thread 7242 and the transmission member thread 7231, the transmission member 7230 moves along the X-axis. On the other hand, as... Figures 7C to 7E In the embodiment shown, the end of the transmission member 7230 near the hook 7400 has a flange 7232 that engages with the interference portion 7222 of the drive member 7220. Thus, when the transmission member 7230 moves along the X-axis, it can drive the drive member 7220 to move along the X-axis, thereby changing the opening width of the front end 7410.
