[0037] In addition, in the present application, the description such as "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that the technical solutions can be realized by those skilled in the art, and when the combination of technical solutions appears to be contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0038] The embodiment of the present application provides a hook device 100, which is installed on a cabinet door 300 of a key management cabinet 1000 and is used in cooperation with a locking structure of a lock, and the lock is usually an intelligent lock, the locking structure is connected with a key management machine on the key management cabinet 1000 and can be controlled by the key management machine to unlock the hook device 100 provided by the embodiment, and the hook device 100 provided by the embodiment can also be unlocked by operating a mechanical key. Figures 1 to 6 In the embodiment of the present application, the hook device 100 comprises a fixing seat 10, a separation module 20 and a hook 30.

[0039] The fixing seat 10 is used for being fixedly installed on the cabinet door 300 of the management cabinet, the fixing seat 10 is provided with two spaced-apart connecting arms 11, a placing position 12 for placing the separation module 20 is formed between the two connecting arms 11, and a clamping hole 111 is formed in each connecting arm 11. The fixing seat 10 can be fixedly installed on the cabinet door 300 in a non-detachable manner, for example, welding, bonding and the like, and the fixing seat 10 can also be fixedly installed on the cabinet door 300 in a detachable manner, for example, a screw structure lock buckle, clamping and the like.

[0040] The separation module 20 comprises a separation seat 21, two locking pieces 22 and an operating assembly 23, the two locking pieces 22 are slidably installed on the separation seat 21 along the length direction of the separation seat 21, the operating assembly 23 is in transmission connection with the two locking pieces 22 respectively, so that the two locking pieces 22 are close to or away from each other, the separation seat 21 is placed in the placing position 12 and is fixed on the fixing seat 10 by being clamped between the corresponding clamping holes 111 through the two locking pieces 22 in the away movement.

[0041] It can be understood that the operation assembly 23 is mainly used by the operator, and the operator applies external force to the operation assembly 23 to drive the two locking pieces 22 to move respectively, so that the two locking pieces 22 move close to each other or move away from each other. When the separation seat 21 is placed in the placement position 12, the operator applies external force to the operation assembly 23, so that the two locking pieces 22 move away from each other, that is, the two locking pieces 22 move towards the corresponding clamping hole 111, and then are buckled with the corresponding clamping hole 111. At this time, the separation seat 21 is limited by the buckling cooperation between the locking piece 22 and the clamping hole 111, and is fixed on the fixed seat 10, and then the separation module 20 is fixed on the fixed seat 10; when the separation seat 21 is placed in the placement position 12, the operator applies external force to the operation assembly 23, so that the two locking pieces 22 move close to each other, that is, the two locking pieces 22 move away from the corresponding clamping hole 111, and then the buckling cooperation between the two locking pieces 22 and the corresponding clamping hole 111 is released. At this time, the separation seat 21 is no longer limited by the buckling cooperation between the locking piece 22 and the clamping hole 111, and the separation seat 21 and / or the fixed seat 10 under the action of external force, so that the separation seat 21 and the fixed seat 10 are separated, that is, the separation module 20 and the fixed seat 10 are separated.

[0042] The lock hook 30 is fixedly installed on the separation seat 21. Similarly, the lock hook 30 can be fixedly installed on the separation seat 21 by a non-detachable connection mode, such as welding, bonding and the like. The lock hook 30 can also be fixedly installed on the separation seat 21 by a detachable connection mode, such as a screw structure lock, clamping and the like.

[0043] The lock hook 30 is used for locking cooperation with the locking structure of the lock. The lock hook 30 is a prior art lock hook 30, which is mainly used for locking cooperation with the locking structure to lock the cabinet door 300 of the key management cabinet 1000 with the door frame 200. Herein, no detailed description is given.

[0044] The lock hook device 100 provided by the embodiments of the present application is provided with the above structure, and when a special situation occurs, external force can be applied to the operation assembly 23 to make the two locking pieces 22 move close to each other, i.e., the two locking pieces 22 move in a direction away from the corresponding clamping hole 111, thereby releasing the clamping cooperation between the locking piece 22 and the clamping hole 111. At this time, the separation seat 21 is no longer limited by the clamping cooperation between the locking piece 22 and the clamping hole 111, and the cabinet door 300 is pulled to apply external force to the fixing seat 10, so that the fixing seat 10 and the separation seat 21 are separated, i.e., the separation module 20 and the fixing seat 10 are separated from each other. It can be seen that, by applying external force to the operation assembly 23 to release the clamping cooperation between the locking piece 22 and the clamping hole 111, the cabinet door 300 can be pulled to separate the fixing seat 10 and the separation seat 21 from each other, thereby opening the cabinet door 300, so that the keys in the key management cabinet 1000 can be taken out without damaging the cabinet door 300 to take out the keys, and the storage device for storing the mechanical keys of the key management cabinet 1000 also does not need to be damaged, thereby saving time, manpower, material resources and the like.

[0045] It should be emphasized that, when the lock hook device 100 provided by the embodiments of the present application is applied to a lock on the key management cabinet 1000, the lock hook device 100 is usually installed on the inner side of the cabinet door 300, and is usually not directly exposed on the outer surface of the key management cabinet 1000. It is usually only through the emergency operation hole 301 on the cabinet door 300 that part of the structure of the operation assembly 23 is exposed, and the emergency operation hole 301 is usually relatively small and can only allow a small tool to pass through.

[0046] The above-described emergency situation refers to a situation that the key management machine cannot work normally (power failure, other sudden failures, etc.), and personnel without authority need to take keys in an emergency. In these emergency situations, the operator can use a tool to apply external force to the operation assembly 23 through the emergency operation hole 301 to open the key management cabinet 1000 in an emergency. It should be noted that, after the fixing seat 10 and the separation module 20 are separated from each other, if the separation module 20 and the lock hook 30 are not removed from the locking structure of the lock, the two locking pieces 22 cannot be moved by the operation assembly 23 to install the separation module 20 back on the fixing seat 10 due to the influence of the operation space.

[0047] In order to further monitor whether the fixing seat 10 and the separation module 20 are separated from each other, a sticker that can be easily broken can be attached between the fixing seat 10 and the separation module 20, so that when the fixing seat 10 and the separation module 20 are separated from each other, the sticker is torn.

[0048] In some examples, as Figures 4 to 7As shown, the separation seat 21 is provided with a mounting cavity and two first avoiding holes 213, the two first avoiding holes 213 are both arranged in communication with the mounting cavity, and the two first avoiding holes 213 are arranged in one-to-one correspondence with the two clamping holes 111. The two locking pieces 22 are respectively slidably installed in the mounting cavity along the length direction of the separation seat 21, and the two locking pieces 22 respectively extend out of the clamping buckle cooperation between the clamping holes 111 through the corresponding first avoiding holes 213 under the movement away from each other.

[0049] In this way, it is intended to reduce the interference of external factors on the two locking pieces 22, so as to reduce the possibility of non-human separation of the fixing seat 10 and the separation module 20 from each other. At the same time, the mounting cavity can well protect the two locking pieces 22 and other structures.

[0050] In some examples, as shown in the drawings, Figures 5 to 7 As shown, the separation seat 21 includes a seat body 211 and a cover plate 212, the seat body 211 is provided with a mounting groove 2111 extending through along the length direction of the separation seat 21, the cover plate 212 is connected with the separation seat 21 and covers the groove opening of the mounting groove 2111 to form an installation cavity, and the cover plate 212 is provided with a first avoiding hole 213 on both sides in the length direction of the separation seat 21.

[0051] In this way, it is intended to facilitate the installation of the two locking pieces 22 and other components, and to improve the modularization of the hook device 100 and the assembly efficiency of the hook device 100.

[0052] In some examples, as shown in the drawings, Figures 6 to 8 As shown, the two sides of the mounting groove 2111 are respectively provided with clamping grooves 2113, the two clamping grooves 2113 also extend along the length direction of the separation seat 21, the two locking pieces 22 are both flat plates, and the two locking pieces 22 are respectively slidably installed between the two clamping grooves 2113.

[0053] In this way, it is intended to improve the stability of the two locking pieces 22 when moving away from each other or moving close to each other, so as to improve the smoothness of the movement of the two locking pieces 22 by operating the assembly 23.

[0054] In some examples, as shown in the drawings, Figures 4 to 8 As shown, the mounting cavity is also provided with two first limiting grooves 214 arranged at intervals, the two first limiting grooves 214 also extend along the length direction of the separation seat 21, the two locking pieces 22 are both provided with a first limiting portion 221, and the two first limiting portions 221 are respectively inserted and matched with the corresponding first limiting grooves 214 to limit the stroke of the locking piece 22.

[0055] In this way, it is intended to avoid the two locking pieces 22 being excessively separated or excessively contracted, so as to avoid affecting the movement of the two locking pieces 22 moving close to each other after being separated from each other, or avoiding affecting the movement of the two locking pieces 22 moving away from each other after moving close to each other. In this way, it is intended to avoid the two locking pieces 22 being excessively separated or excessively contracted, so as to avoid affecting the movement of the two locking pieces 22 moving close to each other after being separated from each other, or avoiding affecting the movement of the two locking pieces 22 moving away from each other after moving close to each other.

[0056] In some examples, as shown in Figures 4 to 7 The operation assembly 23 includes an elastic member 231 and an operation member 232. The elastic member 231 is elastically mounted between the two locking members 22 to cause the two locking members 22 to approach each other under the action of the elastic member 231. The operation member 232 is movably mounted between the two locking members 22 along the width direction of the separation seat 21 and is in transmission abutment with the two locking members 22, respectively, to cause the two locking members 22 to move away from each other under the movement of the operation member 232 and overcome the action of the elastic member 231. The mounting cavity is also provided with two second avoiding holes 215 for the two ends of the operation member 232 to be exposed outside the surface of the separation seat 21 along the width direction of the separation seat 21.

[0057] In this way, when an external force is applied to the operation member 232, the two locking members 22 are respectively buckled with the corresponding clamping holes 111. When the external force is applied to the operation member 232 again to cancel the transmission action of the operation member 232 on the two locking members 22, the two locking members 22 can quickly approach each other under the action of the elastic member 231, and the buckling cooperation between the locking members 22 and the clamping holes 111 is quickly released.

[0058] In some examples, the elastic member 231 is a spring, and the two ends of the spring are fixedly connected with the two locking members 22, respectively. In some specific mounting modes, each locking member 22 is provided with an elastic mounting portion 224, and the two ends of the spring are fixedly connected with the elastic mounting portions 224 of the two locking members 22, respectively. In some examples, the bottom wall of the mounting groove 2111 is also provided with a guide groove 2112 in sliding cooperation with the elastic mounting portion 224 to improve the stability of the movement of the locking member 22.

[0059] In some examples, as shown in Figures 4 to 8 The mounting cavity is also provided with a second limiting groove 216 extending along the width direction of the separation seat 21. The operation member 232 protrudes a second limiting portion 2324 in plug-in cooperation with the second limiting groove 216 to limit the stroke of the operation member 232. In this way, it is intended to avoid excessive movement of the operation member 232 under the action of an external force, and the second avoiding hole 215 is out of the mounting cavity.

[0060] In some examples, as shown in Figures 6 to 8As shown, the operating member 232 includes, in sequence along the width direction of the separation seat 21, an avoiding portion 2321, a driving portion 2322, and an abutting portion 2323, the length of the avoiding portion 2321 in the length direction of the separation seat 21 is less than the length of the abutting portion 2323 in the length direction of the separation seat 21, and the driving portion 2322 is transitionally arranged between the avoiding portion 2321 and the driving portion 2322. Each locking member 22 is provided with a matching portion 222 on the side facing the other locking member 22, each matching portion 222 is in transmission abutment with the operating member 232, and the operating member 232 moves along the width direction of the separation seat 21, so that the matching portions 222 of the two locking members 22 are in transmission abutment with the avoiding portion 2321, the driving portion 2322, and the abutting portion 2323 in sequence, to overcome the action of the elastic member 231.

[0061] In this way, the operating member 232 has a simple structure, and the reliability of the hook device 100 can be improved. When the separation module 20 is separated from the fixed seat 10, an external force is applied to the operating member 232 to drive the operating member 232 to move, so that the matching portions 222 of the two locking members 22 are in abutment with the abutting portion 2323, the driving portion 2322, and the avoiding portion 2321 in sequence, and the two locking members 22 can quickly approach each other under the action of the elastic member 231.

[0062] In some examples, as shown in Figures 6 to 8 As shown, each matching portion 222 is recessed with a slip stop groove 223, and the two sides of the abutting portion 2323 are provided with slip stop ribs 2325 that are engaged with the slip stop groove 223. In this way, the relative fixed state of the operating member 232 and the two locking members 22 is maintained by the engagement of the slip stop ribs 2325 and the slip stop groove 223, and of course under a certain value of external force, the engagement of the slip stop ribs 2325 and the slip stop groove 223 can be quickly contacted, so that the influence of non-human operation on the hook 30 assembly can be reduced.

[0063] Please refer to Figures 1 to 8 The application also provides a key management cabinet 1000, which comprises a door 300, a door frame 200, and a lock, the lock comprising a locking structure and the hook device 100 of any one of the above embodiments. The specific structure of the hook device 100 is referred to the above embodiments. Since the lock adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The locking structure is fixedly installed on the door frame 200, and the hook device 100 is fixedly installed on the door 300. The door 300 is provided with an emergency operation hole 301, and the emergency operation hole 301 is opposite to the operation.

[0064] It should be noted that the key management cabinet 1000 usually further comprises a key management machine which is electrically connected with the locking structure of the lock, and under normal circumstances, the lock can be controlled by the key management machine to unlock the hook device 100 provided in the embodiment, or can be operated by the mechanical key to unlock the hook device 100 provided in the embodiment.

[0065] When an emergency occurs (for example, the key management machine cannot work normally), the operator can insert a screwdriver, a wooden stick or other tools into the emergency operation hole 301 to apply external force to the operation assembly 23, release the clamping cooperation between the locking part 22 and the clamping hole 111, and then open the key management cabinet 1000.

[0066] In order to further monitor whether the key management cabinet 1000 is opened in an emergency, a sticker can be attached to the inside of the emergency operation hole 301, and when the operator inserts a tool into the emergency operation hole 301 to apply external force to the operation assembly 23, the sticker needs to be broken.

[0067] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields based on the inventive concept of the present application and the content of the specification and drawings are included in the patent protection scope of the present application.
