[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0029] Embodiment 1: like Figures 1 to 6 As shown, the key issuing device includes: a cabinet 1, an outlet part 2, a cover 3, a first channel 4, a pushing part 5 and a key box assembly 6. The cabinet 1 is a hollow structure with an opening on the top. The outlet part 2 is installed in the inner cavity of the cabinet 1 for directional export of keys.

[0030] The lead-out portion 2 includes a first base 21, a mounting frame 22, a guide groove 23 and a guide tube 24. The first base 21 is mounted in the inner cavity of the cabinet 1, and the center of the first base 21 is open. There are several mounting frames 22, which are respectively mounted on the first base 21 at equal intervals along the circumferential direction. There are several guide grooves 23, which are mounted on several mounting frames 22. The guide grooves 23 are arranged to be inclined upward from inside to outside along the radial direction of the first base 21. When the key falls into the guide groove 23, it can slide toward the center of the first base 21 by gravity. One end of the guide tube 24 is mounted at the bottom end of the first base 21, and the other end of the guide tube 24 extends out of the outer wall of the cabinet 1.

[0031] The cover shell 3 is installed on the upper surface of the first base 21, and the cover shell 3 is located on the outside of the guide groove 23. There are a plurality of first channels 4, and the plurality of first channels 4 are equidistantly opened on the circumference of the side wall of the cover shell 3 along the circumferential direction, and the plurality of first channels 4 correspond to the plurality of guide grooves 23 respectively. The key enters the cover shell 3 through the first channel 4 and falls into the guide groove 23, and can slide down precisely in a directional manner.

[0032] Through the control of the guide part 2, it can be ensured that the direction in which the key slides down is accurate, and different guide grooves 23 transmit different keys, thereby ensuring the management of different keys.

[0033] Combination Figure 7 As shown, the key box assembly 6 is introduced. There are several key box assemblies 6, which correspond to the positions of several first channels 4 respectively. The key box assembly 6 includes an outer shell 61, a second channel 62, a sliding channel 63, a mounting seat 64, a second rotating plate 65 and a leaf spring 66. The outer shell 61 is installed on the cover 3, and the position of the outer shell 61 corresponds to the first channel 4. The outer shell 61 serves as a separate key management unit, and the inner cavity can accommodate keys in an upright state passing from top to bottom. Each outer shell 61 only contains the same type of key. The second channel 62 is opened on the side of the outer shell 61 away from the cover 3, and the sliding channel 63 is opened on the lower surface of the outer shell 61. The inner cavity of the outer shell 61 is contracted from top to bottom to ensure that the key can be kept when it slides to the bottom of the inner cavity of the outer shell 61. Figure 7 The mounting seat 64 is mounted on the inner wall of the housing 61, the second rotating plate 65 is rotatably mounted on the mounting seat 64, and the two ends of the leaf spring 66 are respectively connected to the mounting seat 64 and the second rotating plate 65. In the natural state, the second rotating plate 65 blocks the passage of the second channel 62. When subjected to external force, the second rotating plate 65 rotates and deforms the leaf spring 66. After the external force is removed, the second rotating plate 65 is reset by the elastic force of the leaf spring 66.

[0034] The pusher 5 is mounted on the housing 3 and is used to push the key in the housing 61 into the housing 3. Figure 5 and Figure 8 , Fig. 9 As shown, the push part 5 is introduced. The push part 5 includes a mounting plate 51, a slide 52, a push component 53 and a spring 54. The mounting plate 51 is mounted on the housing 3. There are a plurality of slides 52, which are mounted on the mounting plate 51 and correspond to a plurality of first channels 4. The push component 53 is slidably mounted in the slide 52 and corresponds to the first channel 4. The spring 54 is mounted between the push component 53 and the slide 52.

[0035] The push assembly 53 includes a sliding seat 531, a blocking plate 532, a through slot 533, a rotating shaft 534, a first rotating plate 535, a torsion spring 536, a bracket 537 and a key rack 538. The sliding seat 531 is slidably installed in the slideway 52, and the blocking plate 532 is installed on the side of the sliding seat 531 opposite to the cover 3. The upper surfaces of the blocking plate 532 and the sliding seat 531 are flush, and both are in contact with the lower surface of the housing 61, which can ensure that the key in the housing 61 will not fall. The through slot 533 is provided on the sliding seat 531. When the through slot 533 moves to the position corresponding to the sliding channel 63, the key will fall into the through slot 533. The rotating shaft 534 is installed in the through slot 533, and the first rotating plate 535 is rotatably installed on the rotating shaft 534. The two ends of the torsion spring 536 are respectively connected to the first rotating plate 535 and the inner wall of the through slot 533. In the natural state, the first rotating plate 535 is tilted downward. At this time, the space of the through slot 533 is fully open. When subjected to external force, the first rotating plate 535 rotates and closes the through slot 533, and the torsion spring 536 is deformed. After the external force is removed, the first rotating plate 535 is reset by the elastic force of the torsion spring 536.

[0036] When in use, the blocking plate 532 is initially in contact with the bottom of the housing 61. When the key needs to be released, the sliding seat 531 is pushed and the spring 54 is stretched. When the through slot 533 corresponds to the sliding channel 63, the key at the lowest end of the housing 61 falls into the through slot 633. The moving seat 631 continues to move, and the upper surface of the moving seat 631 closes the sliding channel 63. When the through slot 533 passes through the first channel 4 and enters the housing 3, the first rotating plate 535 is no longer limited by the slideway 52 and opens by the elastic force of the torsion spring 536. The key can fall from the through slot 533 into the guide slot 23 and finally slide out through the guide tube 24. When the sliding seat 531 is reset by the pulling force of the spring 54, the first rotating plate 535 closes the through slot 533 again, and then the sliding seat 531 continues to reset. The second key in the housing 61 will enter the through slot 533 and wait for the next key release. At the same time, the key can be prevented from falling into the through slot 533.

[0037] This solution can accurately release keys, ensuring that only one key can be released at a time, while preventing extra keys from being released. By utilizing a mechanical structure, the accuracy of the device can be improved.

[0038] The systems for issuing and returning keys in the key cabinets currently used are separate and cannot be performed synchronously, which not only increases the risk of errors but also makes it difficult to use. To solve this problem, an embodiment of the present invention further provides a key cabinet: Figure 8 As shown, the bracket 537 is installed on the side of the sliding seat 531 away from the blocking plate 532, the key rack 538 is installed on the bracket 537, and the position of the key rack 538 corresponds to the blocking plate 532, the through slot 533 and the key rack 538 are staggered, and the key rack 538 is composed of two horizontal bars staggered up and down and a vertical bar connecting the two horizontal bars. The cross section of the horizontal bar at the bottom is V-shaped, and the key can be placed upright in it. And the position of the second rotating plate 65 corresponds to the key rack 538. Figures 4 to 6 The inner cavity of the cabinet 1 is also equipped with a rotating seat 12 and a motor 7. A gear ring 8 is installed at the bottom of the rotating seat 12. A gear 9 is installed at the output end of the motor 7, and the gear ring 8 and the gear 9 are meshed and connected. A driving component 10 is installed on the rotating seat 12. Turning on the motor 7 can rotate the gear 9, and then the gear ring 8 and the rotating seat 12 rotate, so that the driving component 10 can be aligned with any push part 5. Among them, the motor 7 uses the Yaskawa Sigma-5 series motor, which has the ability to accurately control the number of turns, and has a self-locking function. The output end can be locked after stopping.

[0039] The driving assembly 10 includes a fixing frame 101, an electric push rod 102 and a recovery part 11. The fixing frame 101 is mounted on a rotating seat 12, and the electric push rod 102 is mounted on the fixing frame 101. When the electric push rod 102 is turned on, the output end thereof can be used to push the pushing assembly 53 to move. A battery 15 for powering the electric push rod 102 can be mounted on the lower surface of the fixing frame 101, thereby shortening the length of the wire of the external power supply and preventing the wire from being entangled.

[0040] Combination Figures 10 to 13, the recovery part 11 is introduced. The recovery part 11 includes a protective shell 111, a recovery slot 112, a connecting slot 113, a guide frame 114, an opening and closing plate 115, a positioning slot 116, a limiting slot 117, a driving frame 118 and a lever 119. The protective shell 111 is installed on the top of the fixed frame 101, and the recovery slot 112 and the connecting slot 113 are respectively installed on the upper surface and the lower surface of the protective shell 111. The positions of the recovery slot 112 and the connecting slot 113 correspond to each other. The key can enter the protective shell 111 through the recovery slot 112 and slide out from the connecting slot 113. The internal space of the recovery slot 112 is adapted to the size of the key. The key needs to be placed upright to enter the recovery slot 112 to ensure that the key always remains upright during the sliding process. The position of the connecting slot 113 corresponds to the key rack 538. The key can fall on the key rack 538 at the corresponding position through the connecting slot 113, which is located on the crossbar at the bottom. The guide frame 114 is installed in the protective shell 111. The guide frame 114 is arranged in a square shape. There are two opening and closing plates 115, which are symmetrically installed on the guide frame 114, and the opening and closing plates 115 are clamped with the guide frame 114 to ensure the stability of the movement of the opening and closing plates 115. The two opening and closing plates 115 are arranged to be tilted downward on opposite sides. When the two opening and closing plates 115 are attached to each other, the tilted parts of the two form a V-shaped space to ensure that the key can be placed upright in it. The positioning groove 116 is provided on the opening and closing plate 115, the limiting groove 117 is provided on the protective shell 111, the driving frame 118 is arranged in a V-shaped configuration, the top of the driving frame 118 extends from the limiting groove 117 into the protective shell 111, the bottom of the driving frame 118 is connected to the output end of the electric push rod 102, and the lever 119 is slidably installed in the positioning groove 116, wherein the positioning groove 116 includes an oblique groove 1161 and a straight groove 1162, the oblique groove 1161 is connected to the straight groove 1162, when the driving frame 118 moves, the lever 119 slides from the oblique groove 1161 into the straight groove 1162, and the two opening and closing plates 115 are separated, and the key in the V-shaped space will fall downward. On the contrary, the two opening and closing plates 115 approach each other until they fit together.

[0041] In this embodiment, in order to achieve accurate equipment operation control, the system is also equipped with an external control component 13, such as Fig.14As shown, the component includes a programmable logic controller PLC and an encoder. The PLC is responsible for receiving input signals and outputting control instructions, while the encoder is used to feedback the rotation angle or number of turns of the motor 7 in real time, and adjust the extension length of the output end of the electric push rod 102 according to demand. Before use, it is necessary to set it through the encoder according to the specific position of each push part 5, and accurately control the rotation angle or number of turns of the motor 7 to ensure that the drive component 10 is accurately docked with the push part 5. During operation, the PLC receives the setting parameters and converts them into control instructions for the motor 7. The user only needs to select the corresponding housing 61 and the position of the push part 5, and the PLC can send a start signal to the motor 7, and the motor 7 will then start to rotate according to the speed set by the encoder. The system monitors the number of turns of the motor 7 in real time. If it is detected that the motor 7 rotates to a predetermined number of turns, the PLC will send a stop signal. After the motor 7 stops, the PLC will maintain the lock signal to prevent misoperation in the unlocked state. At this time, the drive component 10 and the push part 5 are aligned, and the key issuance and key return operations can be performed. By re-entering the setting or manual operation, the PLC can send an unlock signal to allow the motor 7 to restart. The control component 13 and the control method thereof are both prior art. The PLC model is S7-1200, which is suitable for small and medium-sized automation systems. The encoder model is ECN 13, which is suitable for high-precision position feedback.

[0042] like Fig.14 As shown, a lifting frame 14 is installed on the lower surface of the cabinet 1, which is used to lift the device off the ground so that the end of the conduit 24 extending out of the cabinet 1 is at a suitable height to facilitate taking the key.

[0043] In addition, another embodiment of the present invention further provides a method for using a key cabinet, comprising the following steps: Turn on the motor 7 to drive the gear 9 to rotate, and then drive the gear ring 8 to rotate, so that the rotating seat 12 drives the driving assembly 10 to rotate to the push part 5 at the specified position; The electric push rod 102 is turned on, and its output end pushes the push assembly 53 to move toward the cover 3, and at the same time, the spring 54 is stretched, and the sliding seat 531 and the blocking plate 532 move in contact with the lower surface of the housing 61. When the through slot 533 corresponds to the sliding channel 63, the key at the bottom of the housing 61 will fall into the through slot 533 through the sliding channel 63; The push assembly 53 continues to move. When the through slot 533 passes through the first channel 4 and enters the inner cavity of the housing 3, the first rotating plate 535 opens under the action of the torsion spring 536. The key falls from the through slot 533 into the guide slot 23 and slides out of the guide tube 24. The key is released. The output end of the electric push rod 102 is reset, and the pulling force of the spring 54 is used to reset the pushing assembly 53. When the through slot 533 corresponds to the sliding channel 63 again, the second key in the shell 61 will fall into it. When the pushing assembly 53 moves toward the cover 3 again, the key will be released. At the same time, since the through slot 533 is filled, no new key will fall into it during this process.

[0044] When returning the key, the method of use is proposed, including the following steps: The returned key is placed through the recovery slot 112, and the key enters the protective shell 111 in an upright state and falls at a position where the two opening and closing plates 115 contact each other; The driving assembly 10 is aligned with the position of the housing 61 to which the key belongs, and the electric push rod 102 is turned on. Before the output end of the electric push rod 102 contacts the pushing assembly 53, the driving frame 118 is driven to move, and the lever 119 slides in the inclined slot 1161, and at the same time, the two opening and closing plates 115 are driven to separate from each other. At this time, the key falls and lands on the crossbar at the bottom of the key rack 538; The output end of the electric push rod 102 continues to extend, and starts to drive the push assembly 53 to move and stretch the spring 54. The lever 119 moves in the straight groove 1162, and will not continue to change the position of the opening and closing plate 115. At the same time, the movement of the push assembly 53 will use the key rack 538 to drive the returned key shell 61 to move. The key rack 538 enters the shell 61 through the second channel 62, and at the same time, the second rotating plate 65 is used to block the key to fit the vertical rod of the key rack 538. At this time, the returned key is limited, and the key rack 538 continues to move. The second rotating plate 65 is forced to rotate and deform the leaf spring 66. When the key completely enters the shell 61, the second rotating plate 65 is separated from the contact with the key and reset by the elastic force of the leaf spring 66. The output end of the electric push rod 102 is reset, and the pushing component 53 is reset under the pulling force of the spring 54. At this time, the key rack 538 is reset synchronously. The key on the key rack 538 is blocked by the second rotating plate 65 and will not be reset. After the key rack 538 is reset and leaves the shell 61, the key loses its support and falls into the inner cavity of 61, completing the return.

[0045] At the same time, as the output end of the electric push rod 102 is reset, the driving frame 118 is reset, and the lever 119 returns from the straight groove 1162 to the inclined groove 1161, and the two opening and closing plates 115 contact each other again, waiting for the next key return operation.

[0046] It is worth noting that when returning the key, during the movement of the pushing component 53, the output end of the electric push rod 102 is not fully extended, the moving distance of the pushing component 53 does not reach the full moving range, and the sealing plate 532 is always in contact with the lower surface of the shell 61. The key will not be issued during this process.

[0047] Embodiment 2: In order to prevent the key from falling into the device during the key return process, this embodiment is proposed. The difference from the first embodiment is that a blocking plate 16 is installed on the top of the cabinet 1. Fig.15 As shown, the blocking rotating plate 16 is connected to the recovery groove 112. When the recovery groove 112 moves in a circle, the blocking rotating plate 16 rotates synchronously. The blocking rotating plate 16 can be used to block the gap of the device to prevent the key from falling into the device.

[0048] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
