Description

Technical Field

[0001] This application relates to the field of lock technology, and more specifically, to a cabinet identification sign. Background Technology

[0002] In power plants, substations, and converter stations, there are numerous similar-looking monitoring and protection cabinets. To prevent misoperation, staff typically need to label relevant locks or equipment when inspecting or repairing electrical equipment to ensure the safety of personnel and equipment. Currently, even after unlocking the lock, maintenance personnel still need to completely remove the entire label and manually flip it to change its indicated operating status. This operation is not only cumbersome and inefficient, but also results in the inability to accurately transmit equipment status information in real time, easily leading to the risk of misoperation, causing inconvenience for daily maintenance, and reducing system reliability and operational efficiency. Utility Model Content

[0003] This application provides a cabinet sign that allows switching of the working status indicated by the sign without disassembling it.

[0004] This application provides a cabinet identification sign, including an identification sign assembly, a locking base, a detachable base, a first rotating shaft, a second rotating shaft, and a lock. The locking base, detachable base, and lock are all installed in the cabinet. The first rotating shaft is rotatably mounted on the locking base, and the second rotating shaft is rotatably mounted on the detachable base. Both ends of the identification sign assembly are respectively connected to the first and second rotating shafts. The identification sign assembly can be flipped to switch between a first working state and a second working state. The locking base includes a fixed bracket, a movable bracket, and a connector. The fixed bracket is fixedly mounted on the lock, and the movable bracket is connected along the first and second rotating shafts. A rotating shaft is axially movably mounted on a fixed bracket, and a movable bracket is sleeved on the first rotating shaft. The fixed bracket and the movable bracket enclose a receiving cavity. The locking base has a locked position and an unlocked position. In the locked position, the volume of the receiving cavity decreases, and the movable bracket restricts the rotation of the first rotating shaft to limit the switching of the sign assembly between a first working state and a second working state. In the unlocked position, the volume of the receiving cavity increases, and the movable bracket releases the restriction on the first rotating shaft and the sign assembly. A connector is connected to the movable bracket, and a lock is used to lock or unlock the connector when the locking base is in the locked position.

[0005] Specifically, when it is necessary to switch the working state indicated by the sign, the connector is unlocked by the lock, so that the movable bracket can drive the connector to move relative to the lock, thereby allowing the locking base to switch from the locked position to the unlocked position. This allows the movable bracket to no longer restrict the rotation of the first rotating shaft, so that the sign assembly can be flipped to switch between the first working state and the second working state. After the working state is switched, the movable bracket is moved to the locked position, thereby restricting the rotation of the first rotating shaft. Then, the connector is locked by the lock, thereby fixing the locking base in the locked position and restricting the switching of the working state of the sign assembly.

[0006] In the above technical solution, after unlocking the connector using the lock, simply sliding the movable bracket to position the locking base in the unlocked position allows the switching of the operating status indicated by the sign component, eliminating the need to completely disassemble the indicator component. This simplifies the operation for maintenance personnel, improves their operational efficiency, enhances the real-time transmission efficiency of equipment status information, and reduces the risk of misoperation.

[0007] In some embodiments, a first limiting block is provided on the circumferential surface of the first rotating shaft, and the movable bracket is provided with a first limiting groove and a second limiting groove. When the sign assembly is in a first working state and the movable bracket is in a locked position, the first limiting block engages with the first limiting groove to restrict the rotation of the first rotating shaft. When the sign assembly is in a second working state and the movable bracket is in a locked position, the first limiting block engages with the second limiting groove to restrict the rotation of the first rotating shaft. When the movable bracket is in an unlocked position, the first limiting block disengages from the first limiting groove and the second limiting groove.

[0008] In the above technical solution, the rotation of the first limiting block is restricted by the first limiting groove and the second limiting groove when the signboard assembly is in the first working state and the second working state, respectively, so as to restrict the switching of the working state of the signboard assembly. The structure is simple and easy to implement.

[0009] In some embodiments, a snap-fit ​​hole is provided on one side of the lock, and an elastic part is provided at the end of the connector away from the movable bracket; when the locking base is in the locked position, the elastic part elastically deforms and passes through the snap-fit ​​hole to snap with the lock, and the first limiting block is located in the first limiting groove or the second limiting groove; when the locking base is in the unlocked position, the elastic part disengages from the lock, and the first limiting block disengages from the first limiting groove and the second limiting groove.

[0010] In the above technical solution, the elastic part of the connector is inserted into the snap-fit ​​hole through elastic deformation. Subsequently, the elastic recovery of the elastic part allows the connector and the snap-fit ​​hole to interfere with each other, thereby connecting the connector with the lock. This fixes the movable bracket, thereby fixing the locking base in the locked position. This prevents the first rotating shaft from rotating relative to the movable bracket, thus fixing the sign assembly in the first or second working state. This facilitates the switching of the sign assembly's state and improves the reliability of the sign assembly during use.

[0011] In some embodiments, the first limiting block is detachably disposed on the first rotating shaft.

[0012] In the above technical solution, by detachably setting the first limiting block on the first rotating shaft, it is convenient to repair and replace the first limiting block.

[0013] In some embodiments, a first groove is provided on the periphery of the first rotating shaft, and a portion of the first limiting block is accommodated in the first groove; the first limiting block is fixed to the first rotating shaft by a threaded connector.

[0014] In the above technical solution, by fixing the first limiting block to the first rotating shaft through a threaded connector, on the one hand, it is convenient to repair and replace the first limiting block; on the other hand, compared with the case where the first limiting block and the first rotating shaft are integrally formed, the manufacturing difficulty of the first rotating shaft is reduced, which is conducive to reducing the production cost of the first rotating shaft.

[0015] In some embodiments, the locking base further includes an elastic element, the two ends of which are respectively connected to a movable bracket and a fixed bracket. The elastic element is used to drive the locking base to switch to the unlocked position after the lock unlocking connector is engaged.

[0016] In the above technical solution, by incorporating an elastic element, after the lock unlocks the connector, the movable bracket can be driven by the elastic element, causing the locking base to move to the unlocked position. This eliminates the need for maintenance personnel to manually move the movable bracket, thus facilitating the switching of the signage component's operating status.

[0017] In some embodiments, the detachable base includes a base body and a magnetic component. A second rotating shaft is rotatably mounted on the base body, and the magnetic component is mounted on the base body. The base body is attracted to the cabinet by the magnetic component.

[0018] In the above technical solution, by setting magnetic components on the base body and attaching the base body to the cabinet through the magnetic components, the disassembly of the cabinet's signboard is facilitated. The structure is simple and easy to implement.

[0019] In some embodiments, the display cabinet sign further includes a first connecting shaft and a first connector. The end face of the first rotating shaft is provided with a first shaft hole, which extends axially along the first rotating shaft. One end of the first connecting shaft is connected to the sign assembly, and the other end of the first connecting shaft is inserted into the first shaft hole. A first mounting hole is provided on the circumferential surface of the first rotating shaft, and a first adjusting hole is provided on the circumferential side of the first connecting shaft. One end of the first connector passes through the first mounting hole and the first adjusting hole in sequence. The first adjusting holes are a plurality of holes spaced apart axially along the first connecting shaft.

[0020] In the above technical solution, multiple first adjustment holes are arranged at axial intervals along the first connecting shaft. This allows adjustment of the length of the first rotating shaft and the first connecting shaft by sequentially passing one end of the first connector through the first mounting hole and different first adjustment holes. This ensures that the cabinet identification sign can be adapted to cabinets of different sizes.

[0021] In some embodiments, the display cabinet sign further includes a second connecting shaft and a second connecting member. The end face of the second rotating shaft is provided with a second shaft hole, which extends axially along the second rotating shaft. One end of the second connecting shaft is connected to the sign assembly, and the other end of the second connecting shaft is inserted into the second shaft hole. A second mounting hole is provided on the circumferential surface of the second rotating shaft, and a second adjusting hole is provided on the circumferential side of the second connecting shaft. One end of the second connecting member passes sequentially through the second mounting hole and the second adjusting hole. The second adjusting holes are a plurality of holes spaced apart axially along the second connecting shaft.

[0022] In the above technical solution, the second adjustment holes are set as multiple holes spaced apart along the axial direction of the second connecting shaft. Then, by passing one end of the second connector through the second mounting hole and different second adjustment holes in sequence, the length of the second rotating shaft and the second connecting shaft is adjusted to improve the adaptability of the cabinet sign.

[0023] In some embodiments, the base body is provided with a third mounting hole, the second rotating shaft is inserted into the third mounting hole, and the hole wall of the third mounting hole is provided with a third limiting groove and a fourth limiting groove; the detachable base also includes an elastic limiting member, which is installed on the second rotating shaft; when the sign assembly is in the first working state, the elastic limiting member cooperates with the third limiting groove; when the sign assembly is in the second working state, the elastic limiting member cooperates with the fourth limiting groove.

[0024] In the above technical solution, by setting up an elastic limiting component, the operation and maintenance personnel can confirm whether the signboard assembly has rotated into place by the feedback when the elastic limiting component cooperates with the third or fourth limiting groove when switching between the first and second working states. This helps to improve the accuracy of the signboard assembly switching between the first and second working states. Attached Figure Description

[0034] In this application, "multiple" means two or more (including two).

[0035] In power plants, substations, and converter stations, there are numerous similar-looking monitoring and protection cabinets. To prevent misoperation, staff typically need to label relevant locks or equipment when inspecting or repairing power equipment to ensure the safety of personnel and equipment. Currently, even after unlocking the lock, maintenance personnel still need to completely remove the label and manually flip it to change its indicated operating status. This operation is not only cumbersome and inefficient but also results in inaccurate and unreal-time transmission of equipment status information, increasing the risk of misoperation, inconveniencing daily maintenance, and reducing system reliability and operational efficiency. Based on these considerations, a new approach is proposed to improve the operational efficiency of maintenance personnel, enhance the real-time transmission of equipment status information, and reduce the risk of misoperation. This application provides a cabinet identification sign, including an identification sign assembly, a locking base, a detachable base, a first rotating shaft, a second rotating shaft, and a lock. The locking base, detachable base, and lock are all installed in the cabinet. The first rotating shaft is rotatably mounted on the locking base, and the second rotating shaft is rotatably mounted on the detachable base. Both ends of the identification sign assembly are respectively connected to the first and second rotating shafts. The identification sign assembly can be flipped to switch between a first working state and a second working state. The locking base includes a fixed bracket, a movable bracket, and a connector. The bracket is fixedly installed on the lock, and the movable bracket is movably installed on the fixed bracket along the axial direction of the first rotating shaft. The movable bracket is sleeved on the first rotating shaft, and the fixed bracket and the movable bracket enclose a receiving cavity. The locking base has a locked position and an unlocked position. In the locked position, the volume of the receiving cavity decreases, and the movable bracket restricts the rotation of the first rotating shaft. In the unlocked position, the volume of the receiving cavity increases, and the movable bracket releases the restriction on the first rotating shaft. The plug is connected to the movable bracket, and the lock is used to lock or unlock the plug when the locking base is in the locked position.

[0036] In this type of cabinet signage structure, when switching the operating state indicated by the signage needs to be performed, the connector is unlocked via a lock, allowing the movable bracket to move the connector relative to the lock. This allows the locking base to switch from the locked to the unlocked position, freeing the movable bracket from restricting the rotation of the first rotating shaft. This enables the signage assembly to flip and switch between a first and a second operating state. After switching, the movable bracket is moved to the locked position, restricting the rotation of the first rotating shaft. The connector is then locked in place by the lock, fixing the locking base in the locked position and thus restricting the switching of the signage assembly's operating state. Therefore, after unlocking the connector, simply sliding the movable bracket to the unlocked position allows switching the operating state indicated by the signage assembly without completely disassembling the component. This simplifies the operation for maintenance personnel, improves their efficiency, enhances the real-time transmission of equipment status information, and reduces the risk of misoperation.

[0037] The following section provides a detailed explanation of the cabinet signage, with reference to the accompanying diagram.

[0038] Please refer to Figures 1-4 , Figure 1 This is a structural schematic diagram of the cabinet identification sign 1000 provided in some embodiments of this application. Figure 2 This is an exploded view of the structure of the signage assembly 100 provided in some embodiments of this application. Figure 3 This is a partial cross-sectional view of the cabinet identification plate 1000 provided in some embodiments of this application when the locking base 200 is in the locked position. Figure 4This is a partial cross-sectional view of a cabinet identification plate 1000 provided in some embodiments of this application when the locking base 200 is in the unlocked position. Embodiments of this application provide a cabinet identification plate 1000, including an identification plate assembly 100, a locking base 200, a detachable base 300, a first rotating shaft 400, a second rotating shaft 500, and a lock 600. The locking base 200, detachable base 300, and lock 600 are all installed in the cabinet. The first rotating shaft 400 is rotatably installed on the locking base 200, and the second rotating shaft 500 is rotatably installed on the detachable base 300. Both ends of the identification plate assembly 100 are respectively connected to the first rotating shaft 400 and the second rotating shaft 500. The identification plate assembly 100 can be flipped to switch between a first working state and a second working state. The locking base 200 includes a fixed bracket 210, a movable bracket 220, and a connector 230. The fixed bracket 210 is fixedly installed on the lock 600, and the movable bracket... The movable bracket 220 is movably mounted on the fixed bracket 210 along the axial direction of the first rotating shaft 400. The movable bracket 220 is sleeved on the first rotating shaft 400. The fixed bracket 210 and the movable bracket 220 surround and form a receiving cavity 200A. The locking base 200 has a locked position and an unlocked position. In the locked position, the volume of the receiving cavity 200A decreases, and the movable bracket 220 restricts the rotation of the first rotating shaft 400 to limit the switching of the sign assembly 100 between the first working state and the second working state. In the unlocked position, the volume of the receiving cavity 200A increases, and the movable bracket 220 releases the restriction on the first rotating shaft 400 and the sign assembly 100. The plug 230 is connected to the movable bracket 220, and the lock 600 is used to lock or unlock the plug 230 when the locking base 200 is in the locked position.

[0039] The signage assembly 100 is a structural component used to display the operating status of the display cabinet. For example, please refer to... Figure 2 The sign assembly 100 includes a sign body 110 and a mounting frame 120. The sign body 110 is sandwiched between two mounting frames 120 along its thickness direction. The indicator portions on opposite sides of the sign body 110 are exposed to the outside through the middle of the mounting frame 120.

[0040] The first working state and the second working state are two positions of the signage component 100, which are used to indicate that the signage cabinet is in different working states.

[0041] In some embodiments, the sign body 110 is marked with "Operating Equipment" and "Under Maintenance Equipment" on opposite sides in its thickness direction, respectively. When the sign assembly 100 is in a first working state, the side of the sign body 110 marked "Operating Equipment" is located away from the cabinet, making it easier for maintenance personnel and staff to observe. When the sign assembly 100 is in a second working state, the side of the sign body 110 marked "Under Maintenance Equipment" is located away from the cabinet, also making it easier for maintenance personnel and staff to observe. Thus, one sign assembly 100 can identify two equipment states, allowing the equipment to be identified as "Operating Equipment" or "Under Maintenance Equipment" based on its current status. This reduces the number of sign assemblies 100 required and lowers costs.

[0042] As the name suggests, the detachable base 300 is a base that can be detachably connected to the screen cabinet. For example, the detachable base 300 can be detachably connected to the screen cabinet by means of bolt connection, snap-fit, etc.

[0043] The first rotating shaft 400 and the second rotating shaft 500 are two rotating shafts that are drive-connected to both ends of the sign assembly 100. Understandably, the drive-connection means that the first rotating shaft 400 and the second rotating shaft 500 are connected to the sign assembly 100 through direct connection or indirect connection through other structural components, enabling rotational transmission. That is, when the sign assembly 100 switches between a first working state and a second working state, it drives the first rotating shaft 400 to rotate relative to the locking base 200, and drives the second rotating shaft 500 to rotate relative to the detachable base 300.

[0044] The locking base 200 is a releasable base for fixing the first rotating shaft 400.

[0045] The fixed bracket 210 and the movable bracket 220 are the two main parts of the locking base 200. For example, the fixed bracket 210 and the movable bracket 220 can be sheet metal parts bent into a shell shape.

[0046] The accommodating cavity 200A is a cavity formed by the inner surfaces of the fixed support 210 and the movable support 220.

[0047] In some embodiments, the fixed bracket 210 is a shell structure with a first opening, and the movable bracket 220 is a shell structure inserted into the fixed bracket 210 through the first opening. The movable bracket 220 has a second opening communicating with the interior of the fixed bracket 210. The fixed bracket 210 and the movable bracket 220 together form a receiving cavity 200A. When the locking base 200 is in the locked position, the movable bracket 220 extends out of the fixed bracket 210 through the first opening to increase the volume of the receiving cavity 200A. When the locking base 200 is in the unlocked position, the movable bracket 220 retracts into the fixed bracket 210 through the first opening to decrease the volume of the receiving cavity 200A.

[0048] In some embodiments, the movable support 220 is a shell structure with a second opening. The movable support 220 is sleeved on the fixed support 210 through the second opening. The fixed support 210 is a shell structure with a first opening communicating with the interior of the movable support 220. The fixed support 210 and the movable support 220 together form a receiving cavity 200A. When the locking base 200 is in the locked position, the movable support 220 disengages from the fixed support 210 to increase the volume of the receiving cavity 200A. When the locking base 200 is in the unlocked position, the movable support 220 is sleeved on the fixed support 210 to decrease the volume of the receiving cavity 200A.

[0049] In some embodiments, the movable bracket 220 is provided with a mounting hole 221, and the first rotating shaft 400 is provided with a first section adapted to the mounting hole 221 and a second section that is interference-fitted with the mounting hole 221. When the locking base 200 is in the locked position, the mounting hole 221 is sleeved outside the second section to restrict the rotation of the first rotating shaft 400; when the locking base 200 is in the unlocked position, the mounting hole 221 is sleeved outside the first section to no longer restrict the rotation of the first rotating shaft 400.

[0050] The connector 230 is a structure used for the transmission connection between the lock 600 and the movable bracket 220. In some embodiments, the connector 230 and the movable bracket 220 can be integrally formed; in other embodiments, the connector 230 and the movable bracket 220 are detachably connected.

[0051] The lock 600 can be used to unlock and lock the cabinet, and to lock or unlock the connector 230 when the locking base 200 is in the locked position.

[0052] Specifically, when it is necessary to switch the working state indicated by the sign, the connector 230 is unlocked by the lock 600, so that the movable bracket 220 can drive the connector 230 to move relative to the lock 600. This allows the locking base 200 to switch from the locked position to the unlocked position, so that the movable bracket 220 no longer restricts the rotation of the first rotating shaft 400. This allows the sign assembly 100 to flip to switch between the first working state and the second working state. After the working state is switched, the movable bracket 220 is moved to the locked position, so that the movable bracket 220 restricts the rotation of the first rotating shaft 400. Then, the connector 230 is locked by the lock 600, thereby fixing the locking base 200 in the locked position and restricting the switching of the working state of the sign assembly 100.

[0053] In this embodiment, after unlocking the connector 230 via the lock 600, simply sliding the movable bracket 220 to bring the locking base 200 to the unlocked position allows the working status indicated by the sign component 100 to be switched, without needing to completely disassemble the indicator component. This simplifies the operation for maintenance personnel, improves their operational efficiency, enhances the real-time transmission efficiency of equipment status information, and reduces the risk of misoperation.

[0054] Please refer to Figures 3-7 , Figure 5 This is an exploded view of the structure of the locking base 200 and the first rotating shaft 400 provided in some embodiments of this application. Figure 6 for Figure 3 Enlarged view of point A in the middle. Figure 7 for Figure 4 Enlarged view at point C. According to some embodiments of this application, a first limiting block 410 is provided on the circumferential surface of the first rotating shaft 400, and a first limiting groove 222 and a second limiting groove 223 are provided on the movable bracket 220. When the signboard assembly 100 is in the first working state and the movable bracket 220 is in the locked position, the first limiting block 410 cooperates with the first limiting groove 222 to restrict the rotation of the first rotating shaft 400. When the signboard assembly 100 is in the second working state and the movable bracket 220 is in the locked position, the first limiting block 410 cooperates with the second limiting groove 223 to restrict the rotation of the first rotating shaft 400. When the movable bracket 220 is in the unlocked position, the first limiting block 410 disengages from the first limiting groove 222 and the second limiting groove 223.

[0055] The first limiting block 410 is a protrusion structure that protrudes at least partially from the circumferential surface of the first rotating shaft 400. In some embodiments, the first limiting block 410 may be integrally formed with the first rotating shaft 400.

[0056] The first limiting groove 222 and the second limiting groove 223 are two grooves that are adapted to the first limiting block 410 in the first working state and the second working state, respectively.

[0057] Understandably, the first limiting groove 222 and the second limiting groove 223 are symmetrically arranged with respect to the rotation axis of the first rotating shaft 400.

[0058] In some embodiments, the movable bracket 220 is provided with an assembly hole 221, one end of the first rotating shaft 400 is inserted into the assembly hole 221, and the hole wall of the assembly hole 221 is recessed to form a first limiting groove 222 and a second limiting groove 223.

[0059] Specifically, when the sign assembly 100 is in the first working state and the movable bracket 220 is in the locked position, the first limiting block 410 engages with the first limiting groove 222. When it is necessary to switch the working state of the sign assembly, the lock 600 is unlocked so that the movable bracket 220 can drive the connector 230 to move, thereby causing the first limiting groove 222 to disengage from the first limiting block 410. Then, the sign assembly 100 is rotated so that the sign assembly 100 switches from the first working state to the second working state, and the first limiting block 410 is aligned with the second limiting groove 223. Subsequently, the movable bracket 220 can drive the connector 230 to move, so that the lock 600 locks the connector 230, thereby causing the second limiting groove 223 to be located outside the first limiting block 410, thereby restricting the rotation of the first rotating shaft 400, and thus fixing the sign assembly 100 in the second working state.

[0060] In some embodiments, a second limiting block 420 is further provided on the circumferential surface of the first rotating shaft 400; when the sign assembly 100 is in the first working state and the locking base 200 is in the locked position, the second limiting block 420 cooperates with the second limiting groove 223 to restrict the rotation of the first rotating shaft 400; when the sign assembly 100 is in the second working state and the locking base 200 is in the locked position, the second limiting block 420 cooperates with the first limiting groove 222 to restrict the rotation of the first rotating shaft 400.

[0061] The second limiting block 420 is another protrusion structure that at least partially protrudes from the circumferential surface of the first rotating shaft 400. In some implementations, the second limiting block 420 may be integrally formed with the first rotating shaft 400.

[0062] Understandably, the first limiting block 410 and the second limiting block 420 are symmetrically arranged with respect to the rotation axis of the first rotating shaft 400.

[0063] Specifically, when the sign assembly 100 is in the first working state and the movable bracket 220 is in the locked position, the second limiting block 420 engages with the second limiting groove 223. When it is necessary to switch the working state of the sign assembly, the lock 600 is unlocked so that the movable bracket 220 can drive the connector 230 to move, thereby causing the second limiting groove 223 to disengage from the second limiting block 420. Then, the sign assembly 100 is rotated so that the sign assembly 100 switches from the first working state to the second working state, and the second limiting block 420 is aligned with the first limiting groove 222. Subsequently, the movable bracket 220 can drive the connector 230 to move, so that the lock 600 locks the connector 230, thereby causing the first limiting groove 222 to be located outside the second limiting block 420, thereby restricting the rotation of the first rotating shaft 400, and thus fixing the sign assembly 100 in the second working state.

[0064] Understandably, by setting the second limiting block 420, when the signboard assembly 100 is in the first working state and the second working state, the second limiting block 420 can cooperate with the second limiting groove 223 and the first limiting groove 222 respectively, thereby improving the reliability of the movable bracket 220 in restricting the rotation of the first rotating shaft 400 when the locking base 200 is in the locked position.

[0065] In some embodiments, a limiting member 430 is provided at one end of the first rotating shaft 400 located in the accommodating cavity 200A. The radial dimension of the limiting member 430 is larger than the radial dimension of the mounting hole 221, so as to restrict the first rotating shaft 400 from disengaging from the mounting hole 221.

[0066] In this embodiment, the rotation of the first limiting block 410 is restricted by the first limiting groove 222 and the second limiting groove 223 when the signboard assembly 100 is in the first working state and the second working state, respectively, so as to restrict the switching of the working state of the signboard assembly 100. The structure is simple and easy to implement.

[0067] Please refer to Figure 3 and Figure 8 , Figure 6 for Figure 3 In the enlarged view at point B, according to some embodiments of this application, a snap-fit ​​hole 611 is provided on one side of the lock 600, and an elastic part 231 is provided at the end of the plug-in 230 away from the movable bracket 220. When the locking base 200 is in the locked position, the elastic part 231 elastically deforms and passes through the snap-fit ​​hole 611 to snap into the lock 600, and the first limiting block 410 is located in the first limiting groove 222 or the second limiting groove 223. When the locking base 200 is in the unlocked position, the elastic part 231 disengages from the lock 600, and the first limiting block 410 disengages from the first limiting groove 222 and the second limiting groove 223.

[0068] For example, the fixed bracket 210 has a through hole 211 on the wall opposite to the movable bracket 220 for the connector 230 to pass through, and the elastic part 231 of the connector 230 passes through the through hole 211 and engages with the snap-fit ​​hole 611.

[0069] Understandably, the connector 230 is inserted into the snap-fit ​​hole 611 through the elastic deformation of the elastic part 231. After the connector 230 is installed in the snap-fit ​​hole 611, the elastic recovery force of the elastic part 231 causes mutual interference between the connector 230 and the snap-fit ​​hole 611, thereby achieving a snap-fit ​​connection between the movable bracket 220 and the lock 600, ensuring that the movable bracket 220 will not detach from the lock 600 during use. In this way, regardless of whether the lock 600 is in the unlocked or locked state, the movable bracket 220 can be inserted into the lock 600, achieving a reliable connection between the movable bracket 220 and the lock 600. This avoids the problems of easy detachment of the movable bracket 220 and inconvenience in use that exist in traditional locks 600.

[0070] For example, the connector 230 is a plate, and the connector 230 has a U-shaped through groove that penetrates the connector 230. The plate portion surrounded by the U-shaped through groove constitutes the elastic part 231. By forming the elastic part 231 with elastic deformation capability by opening a U-shaped through groove on the connector 230, the volume and space occupied by the connector 230 are not increased. In addition, the manufacturing process of the connector 230 in this embodiment is greatly simplified due to its simple structure.

[0071] In some embodiments, the lock 600 includes a lock body 610, a handle 620, a bolt 630, and a button (not shown). The lock body 610 is mounted on the outer surface of the cabinet. A locking hole 611 is provided on the side of the lock body 610 facing the fixed bracket 210. An opening is provided on the side of the lock body 610 away from the cabinet. The handle 620 is disposed on the lock body 610 along a first axis parallel to the outer surface of the cabinet on which the lock 600 is disposed. The handle 620 has a locked state (blocking the opening) and an unlocked state (opening the opening). In the unlocked state, the handle 620 can rotate along a second axis to rotate the bolt 630 connected to the handle 620, thereby unlocking the cabinet door. The second axis is perpendicular to the outer surface of the cabinet on which the lock 600 is disposed. The button is disposed on the lock body 610 and is used to hold the handle 620. When the button holds the handle 620, the handle 620 is in the locked state. Pressing the button releases the handle 620, at which point the handle 620 opens the opening to be in the unlocked state. When the handle 620 is in the unlocked or locked state, the connector 230 can be inserted into the latching hole 611 through the elastic deformation of the elastic part 231, realizing the latching connection between the movable bracket 220 and the lock body 610. Specifically, the process of the connector 230 inserting into the latching hole 611 occurs when the handle 620 is in the unlocked state, and the process of the connector 230 inserting into the latching hole 611 occurs when the handle 620 is in the locked state. The movable bracket 220 is then locked and fixed to the lock body 610.

[0072] In one embodiment, the elastic portion 231 is provided with a limiting protrusion 232, which protrudes from the surface of the connector 230 in a direction perpendicular to the insertion direction of the connector 230. After the connector 230 is inserted into the locking hole 611 from outside the lock body 610, the limiting protrusion 232 can abut against the inner wall of the lock body 610 under the elastic restoring force of the elastic portion 231. The elastic portion 231, which is composed of a plate portion surrounded by a U-shaped through groove, is flush with the connector 230, and has a limiting protrusion 232 protruding from the connector 230. When the connector 230 is inserted into the locking hole 611 from outside the lock body 610, the limiting protrusion 232 can abut against the inner wall of the lock body 610 under the elastic restoring force of the elastic portion 231. This enables the snap-fit ​​connection between the connector 230 and the lock body 610, and further enables the snap-fit ​​connection between the movable bracket 220 and the lock body 610.

[0073] In this embodiment, the elastic part 231 of the connector 230 is inserted into the snap-fit ​​hole 611 through elastic deformation. Subsequently, the elastic recovery of the elastic part 231 allows the connector 230 and the snap-fit ​​hole 611 to interfere with each other, thereby connecting the connector 230 with the latch of the lock 600. This fixes the movable bracket 220, thereby fixing the locking base 200 in the locked position. This prevents the first rotating shaft 400 from rotating relative to the movable bracket 220, thus fixing the sign assembly 100 in the first working state or the second working state. This facilitates the switching of the sign assembly 100's state and improves the reliability of the sign assembly 100 during use.

[0074] Please refer to Figures 3-7 The first limiting block 410 is detachably mounted on the first rotating shaft 400.

[0075] In some embodiments, the first limiting block 410 is engaged with the first rotating shaft 400.

[0076] In some embodiments, a first groove 401 is provided on the periphery of the first rotating shaft 400, and the first limiting block 410 is interference-fitted with the first groove.

[0077] In some embodiments, the first limiting block 410 is connected to the first rotating shaft 400 by a pin.

[0078] In some embodiments, a second limiting block 420 is further provided on the circumferential surface of the first rotating shaft 400. The first limiting block 410 and the second limiting block 420 are symmetrically arranged with respect to the rotation axis of the first rotating shaft 400, and the second limiting block 420 is detachably disposed on the first rotating shaft 400.

[0079] In this embodiment, the first limiting block 410 is detachably disposed on the first rotating shaft 400, thereby facilitating the maintenance and replacement of the first limiting block 410.

[0080] Please refer to Figure 5 and Figure 6 According to some embodiments of this application, a first groove 401 is provided on the periphery of the first rotating shaft 400, and a portion of the first limiting block 410 is accommodated in the first groove 401; the first limiting block 410 is fixed to the first rotating shaft 400 by a threaded connector (not shown in the figure).

[0081] The first groove 401 is a groove on the first rotating shaft 400 for accommodating a portion of the first limiting block 410, and the second groove 402 is a groove on the first rotating shaft 400 for accommodating a portion of the second limiting block 420. It can be understood that the first groove 401 partially abuts against the first limiting block 410 to provide support force to the first limiting block 410, thereby restricting the relative movement of the first limiting block 410 relative to the first rotating shaft 400 along the circumferential direction of the first rotating shaft 400.

[0082] Threaded fasteners can be screws or bolts.

[0083] In some embodiments, a first groove 401 and a second groove 402 are provided on the periphery of the first rotating shaft 400. A portion of the first limiting block 410 is accommodated in the first groove 401, and a portion of the second limiting block 420 is accommodated in the second groove 402. The first limiting block 410 and the second limiting block 420 are fixed to the first rotating shaft 400 by threaded connectors (not shown in the figure).

[0084] The second groove 402 partially abuts against the second limiting block 420 to provide support force to the second limiting block 420, thereby restricting the relative movement of the second limiting block 420 relative to the first rotating shaft 400 along the circumference of the first rotating shaft 400.

[0085] In this embodiment, by fixing the first limiting block 410 to the first rotating shaft 400 through a threaded connector, on the one hand, it is convenient to repair and replace the first limiting block 410; on the other hand, compared with the case where the first limiting block 410 and the first rotating shaft 400 are integrally formed, the manufacturing difficulty of the first rotating shaft 400 is reduced, which is conducive to reducing the production cost of the first rotating shaft 400.

[0086] Please refer to Figures 6-7 According to some embodiments of this application, the locking base 200 further includes an elastic element 240, the two ends of which are respectively connected to the movable bracket 220 and the fixed bracket 210. The elastic element 240 is used to drive the locking base 200 to switch to the unlocked position after the lock 600 unlocks the plug 230.

[0087] The elastic element 240 can be a spring or a structural component such as an elastic rubber component.

[0088] In some embodiments, the locking base 200 further includes a connecting rod 241, one end of which passes through the movable bracket 220 and is threadedly connected to the fixed bracket 210. The elastic element 240 is a spring, which is sleeved on the connecting rod 241 and located within the accommodating cavity 200A. The opposite ends of the elastic element 240 abut against the movable bracket 220 and the fixed bracket 210, respectively.

[0089] Specifically, when the locking base 200 is in the locked position, the volume of the accommodating cavity 200A formed by the movable bracket 220 and the fixed bracket 210 is at its minimum, and the elastic element 240 is compressed. After the lock 600 unlocks the connector 230, the elastic element 240 recovers its elasticity, thereby driving the movable bracket 220 away from the fixed bracket 210, so that the volume of the accommodating cavity 200A increases, thereby making the locking base 200 in the unlocked position.

[0090] In this embodiment, by setting the elastic element 240, after the lock 600 unlocks the connector 230, the movable bracket 220 can be driven by the elastic element 240, so that the locking base 200 moves to the unlocked position. This eliminates the need for maintenance personnel to manually move the movable bracket 220, thus facilitating the switching of the working state of the sign assembly 100.

[0091] Please refer to Figure 9 , Figure 9 This is an exploded view of the detachable base 300 and the second rotating shaft 500 provided in some embodiments of this application. According to some embodiments of this application, the detachable base 300 includes a base body 310 and a magnetic component 320. The second rotating shaft 500 is rotatably mounted on the base body 310, and the magnetic component 320 is mounted on the base body 310. The base body 310 is attracted to the cabinet by the magnetic component 320.

[0092] The base body 310 is the main part of the detachable base 300, and the magnetic component 320 is a structural component of the detachable base 300 used to attach to the cabinet.

[0093] For example, the magnetic component 320 may be a neodymium iron boron magnet, a ferrite magnet, an alnico magnet, or a samarium cobalt magnet, etc.

[0094] In some embodiments, the base body 310 has a mounting hole on the surface that abuts against the cabinet for accommodating the magnetic component 320, and the magnetic component 320 is disposed in the mounting hole by interference fit or adhesive bonding.

[0095] In this embodiment, by setting a magnetic element 320 on the base body 310 and attaching the base body 310 to the cabinet through the magnetic element 320, the cabinet identification sign 1000 can be easily disassembled. The structure is simple and easy to implement.

[0096] Please refer to Figure 5 According to some embodiments of this application, the display cabinet sign 1000 further includes a first connecting shaft 700 and a first connector 710.

[0097] The first connecting shaft 700 is a structural component that drives the first rotating shaft 400 and one end of the sign assembly 100.

[0098] For example, one end of the first connecting shaft 700 away from the first rotating shaft 400 is detachably connected to one end of the sign assembly 100.

[0099] The first shaft hole 403 is a hole provided at the end of the first rotating shaft 400 facing the sign assembly.

[0101] The first connector 710 can be a pin or a screw.

[0102] In this embodiment, multiple first adjustment holes 701 are provided at axial intervals along the first connecting shaft 700. The lengths of the first rotating shaft 400 and the first connecting shaft 700 are adjusted by sequentially passing one end of the first connecting member 710 through the first mounting hole 404 and different first adjustment holes 701. This allows the cabinet identification plate 1000 to be adapted to cabinets of different sizes.

[0103] Please refer to Figure 9 According to some embodiments of this application, the display cabinet sign 1000 further includes a second connecting shaft 800 and a second connecting member 810. A second shaft hole is provided on the end face of the second rotating shaft 500, extending axially along the second rotating shaft 500. One end of the second connecting shaft 800 is connected to the sign assembly 100, and the other end of the second connecting shaft 800 is inserted into the second shaft hole. A second mounting hole 501 is provided on the circumferential surface of the second rotating shaft 500, and a second adjusting hole 801 is provided on the circumferential side of the second connecting shaft 800. One end of the second connecting member 810 passes sequentially through the second mounting hole 501 and the second adjusting hole 801. The second adjusting holes 801 are multiple holes spaced apart axially along the second connecting shaft 800.

[0104] The second connecting shaft 800 is a structural component that drives the second rotating shaft 500 and the other end of the sign assembly 100.

[0105] For example, the two ends of the second connecting shaft 800 away from the second rotating shaft 500 are detachably connected to one end of the sign assembly 100.

[0106] The second shaft hole is a hole provided at the end of the second rotating shaft 500 facing the sign assembly.

[0107] Understandably, the second mounting hole 501 extends radially through the second rotating shaft 500, and the second connecting member 810 can be interference-fitted with the second mounting hole 501, or the second connecting member 810 can be threaded into the second mounting hole 501.

[0108] The second connector 810 can be a pin or a screw.

[0109] In this embodiment, the second adjustment holes 801 are set as a plurality of holes spaced apart along the axial direction of the second connecting shaft 800. Then, by passing one end of the second connector 810 through the second mounting hole 501 and different second adjustment holes 801 in sequence, the length of the second rotating shaft 500 and the second connecting shaft 800 is adjusted to improve the adaptability of the cabinet sign 1000.

[0110] Please refer to Figure 9 According to some embodiments of this application, the base body 310 is provided with a third mounting hole, the second rotating shaft 500 is inserted into the third mounting hole, and the hole wall of the third mounting hole (not shown in the figure) is provided with a third limiting groove (not shown in the figure) and a fourth limiting groove (not shown in the figure); the detachable base 300 also includes an elastic limiting member 510, which is installed on the second rotating shaft 500; when the sign assembly 100 is in the first working state, the elastic limiting member 510 cooperates with the third limiting groove; when the sign assembly 100 is in the second working state, the elastic limiting member 510 cooperates with the fourth limiting groove.

[0112] As the ball 512 moves between the third and fourth limiting grooves, the compression spring 511 is compressed. A portion of the ball 512 away from the third mounting hole wall is connected to the compression spring 511, and a portion of the ball 512 near the third mounting hole wall abuts against the third mounting hole wall.

[0113] In some embodiments, the second rotating shaft 500 is provided with a fourth mounting hole 502 extending radially through the second rotating shaft 500. There can be two balls 512, each disposed at one end of a compression spring 511. The compression spring 511 is located within the fourth mounting hole 502, and the two balls 512 extend from both ends of the fourth mounting hole 502 to abut against the wall of the second shaft hole.
