Abstract
Description
Technical Field
[0001] This application relates to the field of management cabinet technology, and in particular to a lock hook device and a key management cabinet. Background Technology
[0002] Key management cabinets are widely used in power plants, enterprises, institutions, libraries and other places where a lot of keys are needed. The key management machine on the cabinet records the time, type and reason for key use, which improves the level of key management. At the same time, it can effectively prevent accidental key use and reduce the workload of manual recording and the occurrence of misrecording, omission and wrong recording.
[0003] Normally, when retrieving a key, the relevant personnel verify their identity with the key management machine using methods such as fingerprint, facial recognition, password, or card swiping. After successful verification, the lock connected to the key management machine is automatically unlocked, and the key can then be retrieved and used.
[0004] However, special circumstances inevitably arise, such as the key management machine malfunctioning (power outage, other sudden failures, etc.), or unauthorized personnel needing to urgently access keys during emergencies. In such cases, the only way to obtain the keys is to break the cabinet door or damage the storage device for the mechanical keys, thus unlocking the cabinet. This requires significant costs to repair the cabinet door or storage device later, wasting time, manpower, and resources. Utility Model Content
[0005] The main objective of this application is to provide a locking device designed to improve the existing key management cabinet, where the key can only be retrieved by breaking the structure in special circumstances.
[0006] To achieve the above objectives, the lock hook device proposed in this application is applied to locks on key management cabinets. The lock hook device includes a fixed base, a separating module, and a lock hook; wherein,
[0007] The fixing base is used to fix it on the cabinet door of the management cabinet. The fixing base is provided with a receiving groove for placing the separation module and a card hole communicating with the receiving groove.
[0008] The separation module includes a separation seat and an elastic component. The elastic component has an elastic buckle. The separation seat is placed in the receiving groove and is fixed on the fixing seat by the buckle between the elastic buckle and the buckle hole.
[0009] The locking hook is fixedly installed on the separating seat, and the locking hook is used to lock in conjunction with the locking structure of the lock.
[0010] In some embodiments of this application, the separating seat is provided with a mounting cavity and a clearance hole communicating with the mounting cavity. The elastic component includes a movable member and a first elastic member. The movable member is mounted in the mounting cavity through the first elastic member and partially extends out of the mounting cavity through the clearance hole under the action of the first elastic member to form the elastic buckle.
[0011] The separating seat is placed in the receiving groove, and the movable part extends through the clearance hole and engages with the snap-fit hole.
[0012] In some embodiments of this application, the separating seat includes a seat body and a cover plate. The seat body is recessed with a mounting groove, and the cover plate is connected to the seat body and covers the mounting groove to form the mounting cavity.
[0013] In some embodiments of this application, the movable component is provided with a limiting groove, the limiting groove extends along the width direction of the separating seat, the movable component is slidably installed in the mounting groove along the width direction of the separating seat, and the limiting groove is slidably engaged with a limiting block protruding from the bottom wall of the mounting groove.
[0014] In some embodiments of this application, the first elastic member includes two springs, the movable member has a spring-loaded part and an elastic mounting part disposed opposite to each other, the two springs are elastically installed at intervals along the length direction of the separating seat between the side wall of the mounting cavity and the elastic mounting part, and the spring-loaded part extends out of the mounting cavity through the clearance hole under the action of the two springs.
[0015] In some embodiments of this application, the elastic mounting portion is provided with two mounting posts, and the two mounting posts are also spaced apart along the length direction of the separating seat so as to correspond one-to-one with the two springs. Each of the two mounting posts is inserted into one end of the corresponding spring.
[0016] In some embodiments of this application, a second elastic element is also installed between the separation module and the fixed base, so as to elastically drive the separation module to move away from the fixed base when the snap-fit between the elastic buckle and the snap hole is released.
[0017] In some embodiments of this application, the second elastic element includes two springs, one end of which is fixedly installed on the separation module and spaced apart along the length of the separation module, and the other end of which elastically abuts against the bottom wall of the receiving groove.
[0018] In some embodiments of this application, the separating seat is further provided with a limiting part on the side facing the receiving groove, and the side of the limiting part away from the separating seat abuts against the bottom wall of the receiving groove to limit the amount of compression of the second elastic member.
[0019] This application also proposes a lock, wherein the key management cabinet includes a cabinet door, a door frame and a lock, the lock including a locking structure and a lock hook device as described in any one of the above, wherein the locking structure is fixedly installed on the door frame, the lock hook device is fixedly installed on the cabinet door, and the cabinet door has an emergency operation hole, the emergency operation hole being positioned opposite the elastic buckle.
[0020] The locking hook device provided in this application embodiment, through the above-described structural configuration, allows for elastic deformation of the elastic buckle when special circumstances occur. This releases the buckle from its engagement with the locking hole. At this point, pulling the cabinet door applies external force to the fixed seat, separating it from the separation module and opening the cabinet door. Therefore, the technical solution of this application, by applying external force to the elastic buckle to release its engagement with the locking hole, allows the cabinet door to be pulled, separating the fixed seat from the separation module and opening the cabinet door to retrieve the key from the key management cabinet. This eliminates the need to damage the cabinet door or the storage device for the mechanical keys, saving time, manpower, and resources. Attached Figure Description

[0035] Furthermore, the use of terms such as "first" and "second" in this application 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 as "first" or "second" may explicitly or implicitly include at least one of those features. 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. If 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 in this application.
[0036] This application provides a lock hook device 100, which is installed on the cabinet door 200 of a key management cabinet 1000 and used in conjunction with the locking structure of a lock. Typically, this lock is a smart lock, and its locking structure is electrically connected to the key management mechanism on the key management cabinet 1000. The lock hook device 100 can be unlocked under the control of the key management mechanism, or it can be unlocked by operating a mechanical key. Please refer to the reference... Figures 1 to 8 In this embodiment of the application, the locking hook device 100 includes a fixed base 10, a separation module 20, and a locking hook 30.
[0037] The mounting base 10 is used to fix it on the cabinet door 200 of the management cabinet. The mounting base 10 is provided with a receiving groove 11 for placing the separation module 20 and a locking hole 12 communicating with the receiving groove 11. The mounting base 10 can be fixedly installed on the cabinet door 200 by a non-removable connection method, such as welding or bonding. The mounting base 10 can also be fixedly installed on the cabinet door 200 by a detachable connection method, such as screw structure locking or snap-fit.
[0038] The separation module 20 includes a separation base 21 and an elastic component 22. The elastic component 22 has an elastic buckle. The separation base 21 is placed in the receiving groove 11 and is fixed to the fixing base 10 through the snap-fit between the elastic buckle and the snap hole 12. It should be emphasized that the elastic buckle is elastic, that is, the snap-fit between the elastic buckle and the snap hole 12 is elastic. When the external force on the elastic buckle exceeds a certain predetermined value, the elastic buckle will undergo elastic deformation, thereby releasing the snap-fit with the snap hole 12. At this time, the separation module 20 and / or the fixing base 10 will separate from the fixing base 10 under the action of external force. Of course, when the external force on the elastic buckle does not reach the predetermined value, the elastic buckle will not undergo elastic deformation or the elastic deformation is insufficient to release the snap-fit with the snap hole 12, and the separation module 20 will maintain the connection relationship with the fixing base 10, that is, it will be fixed to the fixing base 10.
[0039] The locking hook 30 is fixedly installed on the separation seat 21. Similarly, the locking hook 30 can be fixedly installed on the separation seat 21 by a non-removable connection method, such as welding or bonding. The locking hook 30 can also be fixedly installed on the separation seat 21 by a detachable connection method, such as screw structure locking or snap-fit.
[0040] The lock hook 30 is used to engage with the locking structure of the lock. This lock hook 30 is a prior art lock hook 30, which is mainly used to engage with the locking structure to lock the cabinet door 200 of the key management cabinet 1000 to the door frame 300. It will not be described in detail here.
[0041] The locking hook device 100 provided in this application embodiment, through the above-described structural configuration, allows for the application of external force to the elastic buckle body in special circumstances. This causes the elastic buckle to deform elastically, thereby releasing the engagement between the elastic buckle body and the locking hole 12. At this time, pulling the cabinet door 200 to apply external force to the fixed seat 10 allows the fixed seat 10 to separate from the separation module 20, thus opening the cabinet door 200. Therefore, the technical solution of this application, by applying external force to the elastic buckle body to release the engagement between the elastic buckle body and the locking hole 12, allows pulling the cabinet door 200 to separate the fixed seat 10 from the separation module 20, thereby opening the cabinet door 200 and retrieving the key from the key management cabinet 1000. This eliminates the need to damage the cabinet door 200 to retrieve the key, and also eliminates the need to damage the storage device for the mechanical keys in the key management cabinet 1000, saving time, manpower, and resources.
[0042] It should be emphasized that when the lock hook device 100 provided in this embodiment is applied to the lock on the key management cabinet 1000, the lock hook device 100 is usually installed on the inside of the cabinet door 200. It is usually not directly exposed on the outer surface of the key management cabinet 1000. It usually only exposes part of the structure of the elastic buckle through the emergency operation hole 301 on the cabinet door 200. Moreover, the emergency operation hole 301 is usually quite small, only allowing small tools to pass through.
[0043] The emergency situations described above refer to situations such as the key management machine malfunctioning (power outage, other sudden failures, etc.) or unauthorized personnel needing to urgently access keys. In these emergency situations, the operator can use a tool to apply external force to the elastic buckle through the emergency access hole 301 to open the key management cabinet 1000. It should also be noted that if the fixed base 10 and the separating module 20 are separated, and the separating module 20 and the lock hook 30 are not removed from the locking structure of the lock, due to space constraints, it is impossible to reinstall the separating module 20 onto the fixed base 10 by applying external force to the elastic buckle.
[0044] In some examples, such as Figures 4 to 8As shown, the separating seat 21 is provided with an installation cavity and a clearance hole 213 communicating with the installation cavity. The elastic component 22 includes a movable member 221 and a first elastic member 222. The movable member 221 is installed in the installation cavity through the first elastic member 222, and under the action of the first elastic member 222, part of it extends out of the installation cavity through the clearance hole 213 to form an elastic buckle. The separating seat 21 is placed in the receiving groove 11, and part of the movable member 221 extends out through the clearance hole 213 to engage with the buckle hole 12.
[0045] This design aims to improve the reliability of the engagement between the elastic buckle and the snap-fit hole 12, thereby reducing the possibility of the fixed base 10 and the separation module 20 separating from each other due to non-human factors.
[0046] It needs to be emphasized again that if the fixed base 10 and the separation module 20 are separated from each other, and the separation module 20 and the lock hook 30 are not removed from the locking structure of the lock, due to the limitation of the operating space, the separation module 20 cannot be installed back onto the fixed base 10 by pressing the movable part 221 back into the mounting cavity.
[0047] Meanwhile, in order to further monitor whether the fixing base 10 and the separation module 20 separate from each other, an easily detachable sticker can be affixed between the fixing base 10 and the separation module 20 so that the sticker will tear when the fixing base 10 and the separation module 20 separate from each other.
[0048] In some examples, such as Figures 6 to 8 As shown, the separating seat 21 includes a seat body 211 and a cover plate 212. The seat body 211 has a recessed mounting groove 2111, and the cover plate 212 is connected to the seat body 211 and covers the mounting groove 2111 to form a mounting cavity. This arrangement is intended to facilitate the installation of the elastic component 22 and improve the assembly efficiency of the locking hook 30 assembly. The cover plate 212 can be connected to the seat body 211 by means of screw locking, snap-fit, or other connection methods.
[0049] Understandably, in some examples, the aforementioned clearance hole 213 has a sidewall of the mounting groove 2111, and in some examples, the sidewall of the mounting groove 2111 has a notch, which together with the cover plate 212 forms the aforementioned clearance hole 213.
[0050] In some examples, such as Figure 7 and Figure 8As shown, the movable component 221 is provided with a limiting groove 2211, which extends along the width direction of the separating seat 21. The movable component 221 is slidably mounted on the mounting groove 2111 along the width direction of the separating seat 21, and the limiting groove 2211 is slidably engaged with a limiting block 214 protruding from the bottom wall of the mounting groove 2111. This arrangement aims to limit the range of movement of the movable component 221 along the width direction of the separating seat 21 by the abutting engagement between the limiting block 214 and the groove wall of the limiting groove 2211, so as to avoid the movable component 221 from excessively extending out of the mounting cavity and to avoid the movable component 221 from excessively compressing the first elastic member 222.
[0051] In some examples, such as Figure 7 and Figure 8 As shown, the first elastic member 222 includes two springs, and the movable member 221 has a spring-loaded latch 2212 and an elastic mounting portion 2213 disposed opposite to each other. The two springs are elastically installed between the side wall of the mounting cavity and the elastic mounting portion 2213 along the length direction of the separating seat 21. Under the action of the two springs, the spring-loaded latch 2212 extends out of the mounting cavity through the clearance hole 213. This arrangement aims to improve the reliability of the movable member 221 moving along the width direction of the separating seat 21.
[0052] In some examples, such as Figure 7 and Figure 8 As shown, the elastic mounting part 2213 has two mounting posts 2214 protruding from it. The two mounting posts 2214 are also spaced apart along the length of the separating seat 21 to correspond one-to-one with the two springs. Each mounting post 2214 is inserted into one end of the corresponding spring. This arrangement is intended to facilitate the assembly of the elastic component 22, and at the same time, to prevent the two springs from shifting.
[0053] In some examples, such as Figures 4 to 6 As shown, a second elastic element 40 is also installed between the separation module 20 and the fixed base 10, so that when the snap-fit between the elastic buckle and the latch hole 12 is released, the separation module 20 is elastically driven to move away from the fixed base 10. This arrangement is intended to make the separation of the separation module 20 and the fixed base 10 more seamless, thereby improving the opening efficiency of the key management cabinet 1000.
[0054] In some examples, such as Figures 4 to 6 As shown, the second elastic element 40 includes two springs. One end of each spring is fixedly installed on the separation module 20 and is spaced apart along the length of the separation module 20. The other end of each spring elastically abuts against the bottom wall of the receiving groove 11. This arrangement is intended to facilitate the reinstallation of the separation module 20 onto the fixed base 10 after the separation module 20 is separated from the fixed base 10.
[0055] In some examples, such as Figures 4 to 6As shown, the separating seat 21 is also provided with a limiting part 215 on the side facing the receiving groove 11. The side of the limiting part 215 away from the separating seat 21 abuts against the bottom wall of the receiving groove 11 to limit the amount of compression of the second elastic member 40. This arrangement can prevent the second elastic member 40 from being over-compressed, which would cause the elasticity of the second elastic member 40 to fail.
[0056] In some examples, the limiting portion 215 is disposed around the periphery of the second elastic member 40 to form a groove with an opening; in still other examples, the limiting portion 215 includes at least two spaced-apart pillars.
[0057] Please refer to the reference. Figures 1 to 8 This application also proposes a key management cabinet 1000, which includes a cabinet door 200, a door frame 300, and a lock. The lock includes a locking structure and a hook device 100 as described above. The specific structure of the hook device 100 is as described in the above embodiments. Since this lock adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The locking structure is fixedly installed on the door frame 300, and the hook device 100 is fixedly installed on the cabinet door 200. The cabinet door 200 has an emergency operation hole 201, which is set directly opposite the elastic buckle.
[0058] It should be noted that the key management cabinet 1000 usually also includes a key management machine, which is electrically connected to the locking structure of the lock. Under normal circumstances, the lock can unlock the lock hook device 100 provided in this embodiment under the control of the key management machine, or it can unlock the lock hook device 100 provided in this embodiment under the operation of the mechanical key.
[0059] In case of an emergency (such as when the key management machine is not working properly), the operator can use a screwdriver, wooden stick or other tools to reach into the emergency operation hole 301, apply external force to the elastic buckle 23, release the buckle between the elastic buckle and the locking hole 12, and then open the key management cabinet 1000.
[0060] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
