Description

Technical Field

[0001] This invention relates to the field of locks, and particularly to a lock and locking system. Background Technology

[0002] Existing locks require internal detection switches and batteries to detect open / closed status, resulting in larger lock sizes and higher costs. Furthermore, electronic locks rely on electronic technology, internet connectivity, and power supply. Hacker attacks can cause lock failures, and the need for power also leads to excessively high maintenance costs. Mechanical locks, on the other hand, cannot provide feedback on open / closed status. Summary of the Invention

[0003] This invention provides a lock and locking system that solves the problem that mechanical locks cannot detect whether locking has been completed.

[0004] In a first aspect, embodiments of the present invention provide a lock for use with a computer key, characterized in that the computer key includes a detection component, and the lock includes: a lock body, a lock hook, a locking assembly, a mechanical lock cylinder, a first trigger, and a second trigger; the lock hook is movably connected to the lock body and has a first position in which both ends extend into the lock body and a second position in which at least one end exits the lock body; movably installed in the lock body, when the lock hook is in the first position, the locking assembly is connected to the lock hook such that the lock hook is locked to the lock body; when the lock hook is in the second position, the locking assembly is separated from the lock hook; the mechanical lock cylinder is installed in the lock body, and the mechanical lock cylinder has a relative position to the lock body. The mechanical lock cylinder has a rotatable rotating part that drives the locking assembly. A computer key can be inserted into the mechanical lock cylinder and move the rotating part to an initial position, an unlocked position, and a locked position. The rotation of the mechanical lock cylinder from the initial position to the unlocked position is opposite to its rotation from the initial position to the locked position. A first trigger and a second trigger are located on different sides of the outer periphery of the mechanical lock cylinder. When the computer key moves the mechanical lock cylinder to the unlocked position, the first trigger triggers the detection element to generate an unlock signal. When the computer key moves the mechanical lock cylinder to the locked position, the second trigger triggers the detection element to generate a locking signal.

[0005] According to an embodiment of the present invention, a lock has two first and second triggers installed at different positions on the outer periphery of the mechanical lock cylinder. By installing a detection device in the computer key that can cooperate with the first or second trigger, feedback on the unlocking / locking status of the mechanical lock cylinder can be provided even when the lock body has no power supply. The first and second triggers at different positions within the lock body correspond to the unlocked and locked positions of the mechanical lock cylinder, respectively. The detection device generates different identification signals corresponding to the first and second triggers, thereby distinguishing the unlocked and locked positions of the mechanical lock cylinder. Since the lock body can complete the unlocking / locking identification without active components, security is improved without increasing the size of the lock body.

[0006] According to the foregoing embodiments of the first aspect of the present invention, the lock further includes a clutch switching module, which is installed in the lock body and disposed between the mechanical lock cylinder and the locking assembly. During the process of the mechanical lock cylinder rotating from the initial position to the unlocked position, the clutch switching module first engages the mechanical lock cylinder with the locking assembly to disengage the locking assembly from the lock hook, and then disengages the mechanical lock cylinder from the locking assembly. During the process of the mechanical lock cylinder rotating from the initial position to the locked position, the clutch switching module first engages the mechanical lock cylinder with the locking assembly to connect the locking assembly to the lock hook, and then disengages the mechanical lock cylinder from the locking assembly. The mechanical lock cylinder controls the movement of the locking assembly through the clutch switching module, which can engage or disengage the mechanical lock cylinder and the locking assembly to satisfy the position switching between the locking / unlocking operation and the return of the unlock key.

[0007] According to any of the foregoing embodiments of the first aspect of the present invention, the clutch switching module includes a connecting block, a rotating shaft, and a tumbler. The connecting block is provided with a tumbler groove, and the connecting block is connected to the mechanical lock cylinder, which drives the connecting block to rotate. The rotating shaft is provided with a first through hole and a second through hole, and the rotating shaft can drive the locking assembly to move. The tumbler is movably disposed in the tumbler groove. When the tumbler is inserted into the first through hole or the second through hole, the rotating shaft and the connecting block are engaged in transmission, and the rotating shaft and the connecting block rotate synchronously. When the tumbler exits from the first through hole and the second through hole, the rotating shaft and the connecting block are disengaged in transmission, and the connecting block rotates freely relative to the rotating shaft. The clutch switching module achieves transmission engagement and disengagement through the tumbler. When the tumbler extends out of the tumbler groove and inserts into the first through hole or the second through hole, the rotation of the connecting block drives the rotating shaft to rotate, and the clutch switching module achieves transmission engagement. When the tumbler retracts into the tumbler groove, the rotation of the connecting block does not drive the rotating shaft to rotate, and the clutch switching module achieves transmission disengagement.

[0008] According to any of the foregoing embodiments of the present invention, during the process of the mechanical lock cylinder rotating from the initial position to the unlocked position, the pin first extends into the first through hole to drive the rotating shaft and the connecting block, and then exits the first through hole to drive the rotating shaft and the connecting block apart; during the process of the mechanical lock cylinder rotating from the initial position to the unlocked position, the pin first extends into the second through hole to drive the rotating shaft and the connecting block, and then exits the second through hole to drive the rotating shaft and the connecting block apart. When the first through hole and the second through hole are connected to the pin, different transmission combinations are achieved respectively. The first through hole is used for the unlocking process. The pin is connected to the first through hole, the mechanical lock cylinder drives the connecting block to rotate, and the connecting block drives the rotating shaft to rotate through the pin, and the rotating shaft drives the locking assembly to separate from the lock hook; the second through hole is used for the locking process. The pin is connected to the second through hole, the mechanical lock cylinder drives the connecting block to rotate, and the connecting block drives the rotating shaft to rotate through the pin, and the rotating shaft drives the locking assembly to connect with the lock hook.

[0009] According to any of the foregoing embodiments of the present invention, the clutch switching module further includes a first switching component and a second switching component. The first switching component is movably disposed within the first through hole, and the second switching component is movably disposed within the second through hole. When the tumbler is inserted into the first through hole, the first switching component abuts against the tumbler, and a portion of the first switching component extends out of the first through hole. When the tumbler is inserted into the second through hole, the second switching component abuts against the tumbler, and a portion of the second switching component extends out of the second through hole. The first switching component and the second switching component are used to switch the position state of the tumbler. When the first switching component and the second switching component are completely within the first and second through holes, the tumbler is completely within the tumbler groove, and the connecting block and the rotating shaft transmission are disconnected. When either the first switching component or the second switching component is partially within the first and second through holes, the tumbler extends out from the tumbler groove and inserts into the first or second through hole, and the connecting block and the rotating shaft transmission are engaged.

[0010] According to any of the foregoing embodiments of the present invention, the clutch switching module further includes a module sleeve, which is fixedly disposed relative to the lock body. The module sleeve has a stepped surface that abuts against the first switching member or the second switching member. The stepped surface includes a first part and a second part that are set at different heights. When the clutch switching module is in transmission engagement, when the tumbler extends out from the tumbler groove and inserts into the first through hole or the second through hole, the first switching member or the second switching member abuts against the first part of the stepped surface, and the first switching member or the second switching member is located in the first through hole and the second through hole. When the connecting block drives the rotating shaft to rotate through the tumbler, the first switching member or the second switching member rotates from abutting against the first part of the stepped surface to abutting against the second part. The second part of the stepped surface squeezes the first switching member or the second switching member back into the first through hole or the second through hole. The first switching member or the second switching member squeezes the tumbler back into the tumbler groove, and the transmission between the connecting block and the rotating shaft is disconnected.

[0011] According to any of the foregoing embodiments of the present invention, both the connecting block and the rotating shaft are disposed within the module sleeve. The module sleeve is fixedly installed relative to the lock body. The clutch switching module being disposed within the module sleeve enables modular production, simplifies the installation of the lock, and allows for application to a wider variety of locks.

[0012] According to any of the foregoing embodiments of the present invention, the clutch switching module further includes a limiting member, which is fixedly disposed relative to the module sleeve. The connecting block has a limiting groove, and the limiting member is disposed within the limiting groove. When the limiting member abuts against one end of the limiting groove, the mechanical lock cylinder is in the unlocked position; when the limiting member abuts against the other end of the limiting groove, the mechanical lock cylinder is in the locked position. The limiting member is used to limit the rotation range of the connecting block, thereby limiting the rotation range of the lock cylinder connected to the connecting block.

[0013] According to any of the foregoing embodiments of the present invention, the clutch switching module further includes a positioning member, the positioning member at least partially elastically protruding from the outer peripheral surface of the rotating shaft, and a positioning groove provided on the side wall of the module sleeve, the positioning groove cooperating with the positioning member, such that when the positioning member extends into the positioning groove, the rotating shaft is limited to a preset position relative to the module sleeve. The positioning member and the positioning groove cooperate to limit the lock cylinder to an initial position.

[0014] According to any of the foregoing embodiments of the present invention, the positioning element is a smooth positioning bead, the rotating shaft is provided with a positioning mounting groove, and the smooth positioning bead is disposed in the positioning mounting groove. The smooth positioning bead has a spring inside. When the rotating shaft rotates, the steel ball of the smooth positioning bead retracts. When the rotating shaft rotates to a preset position, the steel ball of the smooth positioning bead pops out under the action of the spring and is locked in the positioning groove.

[0015] According to any of the foregoing embodiments of the present invention, the clutch switching module further includes an elastic element, the two ends of which abut against the ball and the ball slot respectively, and provide an elastic force for the ball to eject from the ball slot. The elastic element can be any elastic element capable of providing an elastic force to the ball, such as a spring or an elastic sleeve.

[0016] According to any of the foregoing embodiments of the present invention, a locking groove is provided on the side of the lock hook, and the locking assembly includes at least one locking rod. The locking rod is movably disposed within the lock body, and the end of the locking rod can extend into or retract from the locking groove to lock the lock hook to the lock body or unlock the lock hook. When the locking rod extends into the locking groove, the lock hook is confined within the lock body by the locking rod, thereby locking. When the locking rod retracts from the locking groove, the lock hook can move freely relative to the lock body, thereby unlocking the lock.

[0017] According to any of the foregoing embodiments of the present invention, the rotating shaft has at least one eccentrically positioned protrusion extending out of the module sleeve. The locking rod is provided with a drive groove, and the protrusion extends into the drive groove. When the rotating shaft rotates, the protrusion presses against the sidewall of the drive groove, thereby driving the locking rod to move. When the rotating shaft rotates, the protrusion also rotates, pressing against the sidewall of the drive groove, thereby driving the locking rod to slide.

[0018] According to any of the foregoing embodiments of the present invention, the lock further includes a lock cylinder sleeve, the mechanical lock cylinder being disposed within the lock cylinder sleeve, the lock cylinder sleeve being installed within the lock body, and the lock cylinder sleeve having two mounting slots, with the first trigger and the second trigger respectively disposed in the two mounting slots. The lock cylinder sleeve is fixedly installed relative to the lock body, and the mechanical lock cylinder can rotate within the lock cylinder sleeve.

[0019] According to any of the foregoing embodiments of the present invention, the unlocking position rotates 90° relative to the initial position along a first rotation direction, and the locking position rotates 90° relative to the initial position along a second rotation direction, wherein the first rotation direction and the second rotation direction are opposite. After the computer key is inserted into the mechanical lock cylinder, rotating it 90° clockwise unlocks the lock, rotating it 90° counterclockwise returns it to the initial position, and after the lock hook is inserted into the lock body, rotating it another 90° counterclockwise locks the lock.

[0020] Secondly, embodiments of the present invention also provide a locking system, including a lock according to any of the foregoing embodiments of the first aspect of the present invention and a computer key, wherein the computer key is adapted to the mechanical lock cylinder, the computer key includes a detection element, wherein when the computer key moves the mechanical lock cylinder to the unlock position, the first trigger element triggers the detection element to generate an unlock signal, and when the computer key moves the mechanical lock cylinder to the locked position, the second trigger element triggers the detection element to generate a locking signal.

[0021] According to the locking system of this embodiment, during the unlocking process, after the computer key is inserted into the mechanical lock cylinder, it rotates 90° clockwise. The tumbler installed in the connecting block first extends into the first through hole, driving the rotating shaft to rotate. The mechanical lock cylinder drives the connecting block of the clutch switching module to rotate, and the rotating shaft drives the locking rod to move out of the lock hook, thus unlocking. The tumbler and the first switching member abut against each other. The first switching member first abuts against the first part of the stepped surface. After rotating a certain angle, the first switching member abuts against the second part of the stepped surface. The second part of the stepped surface pushes the first switching member back into the first through hole. The first switching member pushes the tumbler back into the tumbler slot. The connecting block cannot drive the rotating shaft to rotate through the tumbler. The clutch switching module is in a transmission disengagement state. At this time, the detection element in the computer key senses the first trigger element, thereby determining that this position is the unlocked state, generating an unlocking signal and indicating the unlocked state. During the locking process, the computer key first moves from the unlocking position to the locking position. The lock position is rotated 90° counterclockwise to return to the initial position, and then rotated another 90° counterclockwise. During this process, the pins installed in the connecting block first extend into the second through hole, driving the rotating shaft to rotate in the opposite direction. The mechanical lock cylinder drives the connecting block of the clutch switching module to rotate, and the rotating shaft drives the locking rod to move in the opposite direction. The locking rod inserts into the locking groove on the side of the lock hook, realizing the locking of the lock. The pins and the second switching element abut against each other. The second switching element first abuts against the first part of the stepped surface. After rotating a certain angle, the second switching element abuts against the second part of the stepped surface. The second part of the stepped surface pushes the second switching element back into the second through hole. The second switching element pushes the pins back into the pin slot. The connecting block can no longer drive the rotating shaft to rotate through the pins. The clutch switching module is in a disengaged state. At this time, the detection element in the computer key senses the second trigger element, thereby determining that this position is in a locked state, generating a locking signal and indicating the locked state. This invention uses a mechanical structure to realize the state detection of lock unlocking and locking, making the lock monitoring system form a complete closed loop. At the same time, compared with electronic lock structures, it occupies less space, has lower cost, and higher security. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0048] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0049] This invention provides a lock for use with a computer key, the computer key including a detection component, such as... Figure 1As shown, the lock includes a lock body 100, a lock hook 200, a locking assembly 300, a mechanical lock cylinder 400, a first trigger 610, and a second trigger 620. The lock hook 200 is movably connected to the lock body 100 and has a first position where both ends extend into the lock body 100 and a second position where at least one end is withdrawn from the lock body 100. It is movably installed within the lock body 100. When the lock hook 200 is in the first position, the locking assembly 300 connects to the lock hook 200, locking the lock hook 200 to the lock body 100. When the lock hook 200 is in the second position, the locking assembly 300 separates from the lock hook 200. The mechanical lock cylinder 400 is installed in the lock body 100 and has a rotating part that is rotatable relative to the lock body 100. The mechanical lock cylinder 400 is capable of driving... When the locking assembly 300 is activated, the computer key can be inserted into the mechanical lock cylinder 400, and can drive the rotating part to move to the initial position, the unlocked position, and the locked position. The rotation of the mechanical lock cylinder 400 from the initial position to the unlocked position is opposite to the rotation from the initial position to the locked position. The first trigger 610 and the second trigger 620 are located on different sides of the outer periphery of the mechanical lock cylinder 400. The trigger signals generated by the trigger detection elements of the first trigger 610 and the second trigger 620 are different. When the computer key drives the mechanical lock cylinder 400 to the unlocked position, the first trigger 610 trigger detection element generates an unlock signal. When the computer key drives the mechanical lock cylinder 400 to the locked position, the second trigger 620 trigger detection element generates a locking signal.

[0050] According to an embodiment of the present invention, two first triggers 610 and second triggers 620 are installed on the outer periphery of the mechanical lock cylinder 400 at different positions. By installing a detection element in the computer key that can cooperate with the first or second trigger, feedback on the unlocking / locking status of the mechanical lock cylinder 400 can be provided even when the lock body 100 has no power supply. The first trigger 610 and second trigger 620 at different positions within the lock body 100 correspond to the unlocked and locked positions of the mechanical lock cylinder 400, respectively. When the computer key rotates the mechanical lock cylinder 400 to the unlocked position, the detection element can identify the first trigger 610; when the computer key rotates the mechanical lock cylinder 400 to the locked position, the detection element can identify the second trigger 620. Since the trigger signals generated by the first trigger 610 and the second trigger 620 are different, the unlocked and locked positions of the mechanical lock cylinder 400 are distinguished. Because the lock body can complete the unlocking / locking identification without active components, security is improved without increasing the size of the lock body.

[0051] In this embodiment, the first trigger 610 and the second trigger 620 are a first magnet and a second magnet, with opposite magnetic poles. When the mechanical lock cylinder 400 is in the unlocked or locked position, the first magnet or the second magnet can cause the detection element to generate different detection signals, thereby determining the state of the lock.

[0052] In some other embodiments, the first trigger 610 and the second trigger 620 are RFID (radio frequency identification) tags with different electronic codes, and the detection device is an RFID reader / writer. The RFID reader / writer can read the information of the RFID tag to determine the status of the lock.

[0053] In some embodiments, the lock further includes a clutch switching module 800, which is installed inside the lock body 100 and disposed between the mechanical lock cylinder 400 and the locking component 300. During the process of the mechanical lock cylinder 400 rotating from the initial position to the unlocked position, the clutch switching module 800 first engages the mechanical lock cylinder 400 with the locking component 300 to drive the locking component 300 to separate from the lock hook 200, and then disengages the mechanical lock cylinder 400 from the locking component 300. During the process of the mechanical lock cylinder 400 rotating from the initial position to the locked position, the clutch switching module 800 first engages the mechanical lock cylinder 400 with the locking component 300 to drive the locking component 300 to connect with the lock hook 200, and then disengages the mechanical lock cylinder 400 from the locking component 300. The mechanical lock cylinder 400 controls the movement of the locking component 300 through the clutch switching module 800. The clutch switching module 800 can engage or disengage the mechanical lock cylinder 400 and the locking component 300 to meet the position switching between the locking / unlocking operation and the return of the unlocking key, thus realizing more complex lock function requirements.

[0054] In some embodiments, such as Figures 1 to 5As shown, the clutch switching module 800 includes a connecting block 810, a rotating shaft 820, and a pin 830. The connecting block 810 is provided with a pin groove 810b. The connecting block 810 is connected to the mechanical lock cylinder 400, and the mechanical lock cylinder 400 drives the connecting block 810 to rotate. The rotating shaft 820 is provided with a first through hole 821a and a second through hole 821b. The rotating shaft 820 can drive the locking assembly 300 to move. The pin 830 is movably disposed in the pin groove 810b. When the pin 830 is inserted into the first through hole 821a or the second through hole 821b, the rotating shaft 820 and the connecting block 810 are engaged in transmission, and the rotating shaft 820 and the connecting block 810 rotate synchronously. When the pin 830 is withdrawn from the first through hole 821a and the second through hole 821b, the rotating shaft 820 and the connecting block 810 are disengaged in transmission, and the connecting block 810 rotates freely relative to the rotating shaft 820. The connecting block 810 has a cylindrical structure. A rectangular groove is provided on the back of the connecting block 810. The groove and the connecting piece 700 are rotatably connected. The connecting piece 700 and the mechanical lock cylinder 400 are fixedly connected by bolts. A tumbler groove 810b is provided on the contact surface between the connecting block 810 and the rotating shaft 820. A cylindrical tumbler 830 is disposed in the tumbler groove 810b. A first through hole 821a and a second through hole 821b are provided on the contact surface between the rotating shaft 820 and the connecting block 810. (Clutch / Disengagement) The engagement and disengagement of the transmission in the switching module 800 are achieved through the ball 830. When the ball 830 extends from the ball slot 810b and is inserted into the first through hole 821a or the second through hole 821b, the connecting block 810 rotates, which drives the rotating shaft 820 to rotate, and the clutch switching module 800 engages the transmission. When the ball 830 retracts into the ball slot 810b, the connecting block 810 rotates without driving the rotating shaft 820 to rotate, and the clutch switching module 800 disengages the transmission.

[0055] In some embodiments, during the process of the mechanical lock cylinder 400 rotating from the initial position to the unlocked position, the pin 830 first extends into the first through hole 821a to drive the rotating shaft 820 and the connecting block 810, and then exits the first through hole 821a to drive disconnect the rotating shaft 820 and the connecting block 810; during the process of the mechanical lock cylinder 400 rotating from the initial position to the unlocked position, the pin 830 first extends into the second through hole 821b to drive the rotating shaft 820 and the connecting block 810, and then exits the second through hole 821b to drive disconnect the rotating shaft 820 and the connecting block 810. When the first through hole 821a and the second through hole 821b are connected to the pin 830, they achieve different transmission combinations. The first through hole 821a is used for the unlocking process. When the pin 830 is connected to the first through hole 821a, the mechanical lock cylinder 400 drives the connecting block 810 to rotate. The connecting block 810 drives the rotating shaft 820 to rotate through the pin 830. The rotating shaft 820 drives the locking assembly 300 to separate from the lock hook 200. The second through hole 821b is used for the locking process. When the pin 830 is connected to the second through hole 821b, the mechanical lock cylinder 400 drives the connecting block 810 to rotate. The connecting block 810 drives the rotating shaft 820 to rotate through the pin 830. The rotating shaft 820 drives the locking assembly 300 to connect with the lock hook 200.

[0056] In some embodiments, such as Figure 2 As shown, the clutch switching module 800 also includes a first switching element 841 and a second switching element 842. The first switching element 841 is movably disposed in the first through hole 821a, and the second switching element 842 is movably disposed in the second through hole 821b. When the ball 830 is inserted into the first through hole 821a, the first switching element 841 abuts against the ball 830, and a portion of the first switching element 841 extends out of the first through hole 821a. When the ball 830 is inserted into the second through hole 821b, the second switching element 842 abuts against the ball 830, and a portion of the second switching element 842 extends out of the second through hole 821b. In this embodiment, the first switching element 841 and the second switching element 842 are steel balls, but other shapes such as cylinders or ellipsoids can also be used. The first switching element 841 and the second switching element 842 are used to switch the position state of the ball 830. When the first switching element 841 and the second switching element 842 are completely inside the first through hole 821a and the second through hole 821b, the ball 830 is completely inside the ball groove 810b, and the connecting block 810 and the rotating shaft 820 are disconnected. When the first switching element 841 or the second switching element 842 is partially inside the first through hole 821a and the second through hole 821b, the ball 830 extends out of the ball groove 810b and is inserted into the first through hole 821a or the second through hole 821b, and the connecting block 810 and the rotating shaft 820 are engaged.

[0057] In some embodiments, such as Figure 6As shown, the clutch switching module 800 also includes a module sleeve 850, which is fixedly disposed relative to the lock body 100. The module sleeve 850 has a stepped surface 851 that abuts against the first switching member 841 or the second switching member 842. The stepped surface 851 includes a first portion 851a and a second portion 851b that are set at different heights. When the clutch switching module 800 is in the transmission engagement state, when the tumbler 830 extends from the tumbler groove 810b and inserts into the first through hole 821a or the second through hole 821b, the first switching member 841 or the second switching member 842 abuts against the first portion 851a of the stepped surface 851. The switching element 842 is partially located within the first through hole 821a and the second through hole 821b. When the connecting block 810 drives the rotating shaft 820 to rotate via the ball 830, the first switching element 841 or the second switching element 842 rotates from abutting against the first part 851a of the stepped surface 851 to abutting against the second part 851b. The second part 851b of the stepped surface 851 squeezes the first switching element 841 or the second switching element 842 back into the first through hole 821a or the second through hole 821b. The first switching element 841 or the second switching element 842 squeezes the ball 830 back into the ball groove 810b, and the transmission between the connecting block 810 and the rotating shaft 820 is disconnected. The module sleeve 850 is a hollow cylinder with an inwardly extending flange. The cylinder has longitudinally cut surfaces on its sides to limit the rotation of the module sleeve 850 relative to the lock body 100. Alternatively, a snap-fit ​​element can be provided on the module sleeve 850, or the outer peripheral wall of the module sleeve 850 can be made a non-cylindrical surface to limit its rotation. A stepped surface 851 is provided at the contact point between the flange and the rotating shaft 820. The stepped surface 851 has a first portion 851a and a second portion 851b that are at different heights. The first portion 851a and the second portion 851b are connected by an inclined surface. The first switching element 841 and the second switching element 842 can slide on the first portion 851a and the second portion 851b.

[0058] In some embodiments, both the connecting block 810 and the rotating shaft 820 are disposed within the module sleeve 850. The module sleeve 850 is fixedly installed relative to the lock body 100. The clutch switching module 800 is disposed within the module sleeve 850, which enables modular production, simplifies the installation of the lock, and allows it to be applied to a wider variety of locks.

[0059] In some embodiments, such as Figure 2As shown, the clutch switching module 800 also includes a limiting member 860, which is fixedly set relative to the module sleeve 850. The connecting block 810 has a limiting groove 810a, and the limiting member 860 is set in the limiting groove 810a. When the limiting member 860 abuts against one end of the limiting groove 810a, the mechanical lock cylinder 400 is in the unlocked position. When the limiting member 860 abuts against the other end of the limiting groove 810a, the mechanical lock cylinder 400 is in the locked position. The limiting member 860 can be a fan-shaped, wedge-shaped, or cylindrical structure. The module sleeve 850 has a through hole that matches the cross-sectional shape of the limiting member 860. After the rotating shaft 820, connecting block 810, and tumbler 830 are installed inside the module sleeve 850, the limiting member 860 extends from the through hole of the module sleeve 850 into the limiting groove 810a of the connecting block 810, limiting the rotating shaft 820, connecting block 810, and tumbler 830 within the module sleeve 850. At the same time, when the connecting block 810 rotates relative to the limiting member 860, the limiting member 860 can abut against the side walls on both sides of the limiting groove 810a to limit the rotation range of the connecting block 810, thereby limiting the rotation range of the mechanical lock cylinder 400 connected to the connecting block 810.

[0060] In some embodiments, such as Figure 2 and Figure 6 As shown, the clutch switching module 800 also includes a positioning member 870. The positioning member 870 at least partially protrudes elastically from the outer peripheral surface of the rotating shaft 820. A positioning groove 852 is provided on the side wall of the module sleeve 850. The positioning groove 852 is configured to cooperate with the positioning member 870. When the positioning member 870 extends into the positioning groove 852, the rotating shaft 820 is limited to a preset position relative to the module sleeve 850. The positioning member 870 is fixedly configured relative to the rotating shaft 820. An elastic component such as a rubber protrusion or a spring that does not affect rotation can be installed on the outer peripheral surface of the rotating shaft 820. When rotating, the side wall of the module sleeve 850 squeezes the positioning member 870 to elastically retract. When rotating to the positioning groove 852, the positioning member 870 elastically extends out. The positioning member 870 cooperates with the positioning groove 852 to limit the mechanical lock cylinder 400 to the initial position.

[0061] In some embodiments, the positioning element 870 is a smooth positioning bead, and the rotating shaft 820 is provided with a positioning mounting groove 823, in which the smooth positioning bead is disposed. The smooth positioning bead has a spring inside. When the rotating shaft 820 rotates, the steel ball of the smooth positioning bead retracts. When the rotating shaft 820 rotates to a preset position, the steel ball of the smooth positioning bead pops out under the action of the spring and is locked in the positioning groove 852.

[0062] In some embodiments, such as Figure 2As shown, the clutch switching module 800 also includes an elastic element 880, whose two ends abut against the ball 830 and the ball slot 810b respectively, and provide the ball 830 with an elastic force to extend out of the ball slot 810b. The elastic element 880 can be any elastic component that can provide an elastic force for the ball 830 to extend out of the ball slot 810b, such as a spring or an elastic sleeve.

[0063] In some embodiments, such as Figure 1 As shown, the lock hook 200 has a locking groove 230 on its side. The locking assembly 300 includes at least one locking rod 310, which is movably disposed within the lock body 100. The end of the locking rod 310 can extend into or retract from the locking groove 230 to lock the lock hook 200 to the lock body 100 or unlock the lock hook 200. In this embodiment, there are two locking rods 310. The lock hook 200 has a long hook portion 210 and a short hook portion 220. A lock hook reset member 900 is disposed between the long hook portion 210 and the lock body 100. A locking groove 230 is provided on the side of the long hook portion 210 and the short hook portion 220 respectively. The locking rod 310 is slidably disposed between the long hook portion 210 and the short hook portion 220. The end of the locking rod 310 and the locking groove 230 are adapted in shape. When locking, the lock hook 200 is pressed down first. When the locking rod 310 extends into the lock body 100, the two locking rods 310 slide outwards in a direction away from each other, and the ends of the locking rods 310 extend into the locking groove 230. The lock hook 200 is confined within the lock body 100 by the locking rods 310, thus achieving locking. When unlocking, the two locking rods 310 slide out of the locking groove 230 in a direction closer to each other, and the short hook part 220 of the lock hook 200 pops out of the lock body 100 under the elastic action of the lock hook reset member 900, thus unlocking the lock.

[0064] In some embodiments, such as Figure 1 , Figure 2 and Figure 7 As shown, the rotating shaft 820 has at least one eccentrically positioned protrusion 822 extending out of the module sleeve 850. The locking rod 310 has a drive groove 320, into which the protrusion 822 extends. When the rotating shaft 820 rotates, the protrusion 822 presses against the side wall of the drive groove 320, thereby driving the locking rod 310 to move. In this embodiment, a protrusion 822 is provided on each of the two circumferentially opposite sides of the rotating shaft 820. The two protrusions 822 extend into the drive grooves 320 of the two locking rods 310 respectively. When the rotating shaft 820 rotates, the protrusions 822 also rotate, pressing against the side wall of the drive groove 320, causing the locking ends of the two locking rods 310 to move closer to or further away from each other, thereby simultaneously extending into or out of the locking groove 230, realizing the locking or unlocking of the lock hook 200.

[0065] In some embodiments, such as Figure 8As shown, the lock also includes a lock cylinder sleeve 500, within which a mechanical lock cylinder 400 is disposed. The lock cylinder sleeve 500 is installed within the lock body 100. The lock cylinder sleeve 500 has two magnet mounting slots 510, with a first trigger 610 and a second trigger 620 respectively disposed within the two magnet mounting slots 510. The lock cylinder sleeve 500 is fixedly installed relative to the lock body 100, and the mechanical lock cylinder 400 can rotate within the lock cylinder sleeve 500. In this embodiment, the first trigger 610 and the second trigger 620 are respectively positioned at 0° and 180° on the lock cylinder sleeve 500.

[0066] In some embodiments, the unlocked position rotates 90° relative to the initial position along a first rotation, and the locked position rotates 90° relative to the initial position along a second rotation, with the first and second rotations being opposite. After the computer key is inserted into the mechanical lock cylinder 400, rotating it 90° clockwise unlocks the lock. After rotating it 90° counterclockwise, it returns to the initial position. After the lock hook 200 is inserted into the lock body 100, rotating it 90° counterclockwise again locks the lock.

[0067] This invention provides a locking system, including a lock according to any of the above embodiments and a computer key, such as... Figures 1 to 12 As shown, the computer key and the mechanical lock cylinder 400 are compatible. The computer key includes a detection component. When the computer key moves the mechanical lock cylinder 400 to the unlock position, the first trigger 610 triggers the detection component to generate an unlock signal. When the computer key moves the mechanical lock cylinder 400 to the lock position, the second trigger 620 triggers the detection component to generate a lock signal.

[0068] During the unlocking process, after the computer key is inserted into the mechanical lock cylinder 400, it is rotated 90° clockwise. The pin 830 installed in the connecting block 810 first extends into the first through hole 821a, driving the rotating shaft 820 to rotate. The mechanical lock cylinder 400 drives the connecting block 810 of the clutch switching module 800 to rotate. The rotating shaft 820 drives the locking assembly 300 to move out of the lock hook 200, thus unlocking. The pin 830 and the first switching piece 841 abut against each other. The first switching piece 841 first abuts against the first part 851a of the stepped surface 851. After rotating a certain angle, the first switching piece 841 and the stepped surface 851... The second part 851b abuts against the first switching element 841, which pushes the first switching element 841 back into the first through hole 821a. The first switching element 841 pushes the tumbler 830 back into the tumbler groove 810b. The connecting block 810 cannot drive the rotating shaft 820 to rotate through the tumbler 830. The clutch switching module 800 is in a disengaged state. At this time, the detection element in the computer key senses the first trigger 610, thereby determining that this position is in the unlocked state, generating an unlock signal and indicating the unlocked state. During the locking process, the computer key first rotates 90° counterclockwise from the unlocked position back to the first trigger 610. Upon reaching the initial position, the mechanism rotates counterclockwise by 90°. During this process, the pin 830 installed in the connecting block 810 first extends into the second through hole 821b, causing the rotating shaft 820 to rotate in the opposite direction. The mechanical lock cylinder 400 drives the connecting block 810 of the clutch switching module 800 to rotate, and the rotating shaft 820 drives the locking assembly 300 to move in the opposite direction. The locking rod 310 inserts into the locking groove 230 on the side of the lock hook 200, thus locking the lock. The pin 830 and the second switching member 842 abut against each other. The second switching member 842 first abuts against the first part 851a of the stepped surface 851, and then rotates by a certain angle. After the second switching element 842 abuts against the second part 851b of the stepped surface 851, the second part 851b of the stepped surface 851 pushes the second switching element 842 back into the second through hole 821b, and the second switching element 842 pushes the tumbler 830 back into the tumbler groove 810b. The connecting block 810 cannot drive the rotating shaft 820 to rotate through the tumbler 830, and the clutch switching module 800 is in a transmission disengagement state. At this time, the detection element in the computer key senses the second trigger element 620 and generates a trigger signal, thereby determining that this position is in a locked state, generating a locked signal and indicating the locked state. This invention uses a mechanical structure to realize the state detection of lock unlocking and locking, so that the lock monitoring system forms a complete closed loop. At the same time, compared with electronic lock structures, it occupies less space, has lower cost, and higher security.

[0069] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
