Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a comprehensive distribution box mechanical locking device. Background Technology

[0002] As is well known, distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits. To ensure equipment safety, existing integrated distribution boxes are usually equipped with door locks to prevent unauthorized personnel from opening the box at will.

[0003] Currently, integrated distribution boxes are generally equipped with only a single door lock to prevent unauthorized personnel from opening the box. However, this single-lock protection mode has significant security vulnerabilities in equipment maintenance scenarios. When maintenance personnel shut down the equipment inside the box for inspection, the existing single door lock only provides basic protection against unauthorized opening, without any additional maintenance-specific locking device on the door panel. This means that even if maintenance personnel have de-energized the equipment inside the box, other personnel can still easily open the distribution box door panel by opening the regular door lock, and access the internal equipment under maintenance, which could lead to electric shock, accidental equipment startup, and other safety accidents, seriously threatening the lives of maintenance personnel. It could also cause power system failures and equipment damage, resulting in unnecessary economic losses and power supply interruptions. Summary of the Invention

[0004] Technical problems to be solved

[0005] In order to overcome the problem that the single lock of the existing integrated distribution box mechanical interlocking device lacks maintenance protection, this utility model provides an integrated distribution box mechanical interlocking device with maintenance protection lock to prevent accidental opening.

[0006] Technical solution

[0008] Preferably, the outer side of the card block is provided with two sets of mounting plates, one side of the mounting plate is provided with a spring, and the end of the spring away from the mounting plate is provided on the outer side of the fixing plate.

[0009] Furthermore, two sets of limiting rods are provided on one side of the fixing plate, and the mounting plate is slidably disposed on the outside of the limiting rods.

[0010] Furthermore, a central shaft is provided on the side of the mounting bracket away from the connecting plate, and a pulley is rotatably provided on the outer side of the central shaft.

[0011] In a further embodiment, the drive assembly includes a rotary motor and a horizontal plate. The rotary motor is located on one side of the machine body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-5 A mechanical interlocking device for an integrated distribution box includes a body 1, a door panel 4 on one side of the body 1, and a door lock inside the door panel 4. The door lock is a conventional door lock used to fix the door panel 4 and the body 1. The door lock is a first locking method. A drive assembly 3 and two sets of fixing assemblies 2 are provided on one side of the body 1. The fixing assemblies 2 are a second locking method, and one side of the drive assembly 3 is fixedly connected to one side of each of the two sets of fixing assemblies 2.

[0026] First, refer to Figures 1 to 4 In this embodiment, the fixing component 2 includes a fixing plate 201, which is welded to one side of the body 1. A locking block 202 is slidably connected inside the fixing plate 201, and both sides of the locking block 202 penetrate the fixing plate 201. A protrusion 207 is welded inside the locking block 202. The protrusion 207 is semi-elliptical and located inside the fixing plate 201. A mounting bracket 206 is slidably connected inside the fixing plate 201. A connecting plate 205 is welded to one side of the mounting bracket 206. The side of the connecting plate 205 away from the mounting bracket 206 penetrates the fixing plate 201 and is fixedly connected to one side of the drive component 3.

[0027] Specifically, to prevent the mounting bracket 206 from being damaged by friction when pushing the protrusion 207, a central shaft 211 is fixedly connected to the side of the mounting bracket 206 near the protrusion 207. A pulley 210 is rotatably connected to the outside of the central shaft 211. The pulley 210 can replace the mounting bracket 206 in contact with the protrusion 207, thus avoiding the situation where the mounting bracket 206 is damaged by friction against the protrusion 207.

[0028] Specifically, to prevent the locking block 202 from misaligning during movement, two sets of limiting rods 208 are welded to one side of the fixing plate 201, and two sets of mounting plates 204 are welded to the outside of the locking block 202. The mounting plates 204 are slidably connected to the outside of the limiting rods 208. Thus, on the one hand, the limiting rods 208 maintain the balance of the locking block 202 during movement, preventing the locking block 202 from becoming unbalanced and wobbling during movement, and ensuring the normal displacement of the locking block 202. On the other hand, the limiting rods 208 restrict the direction of the locking block 202, preventing the device from failing due to misalignment of the locking block 202, and ensuring the normal use of the device.

[0029] Meanwhile, in order to enable the locking block 202 to move back quickly, a spring 203 is fixedly connected to the side of the mounting plate 204 near the fixing plate 201, and the end of the spring 203 away from the mounting plate 204 is fixedly connected to the outside of the fixing plate 201. Thus, when the locking block 202 is pushed, the spring 203 will be squeezed by the mounting plate 204, and when the locking block 202 is no longer pushed, the spring 203 will drive the locking block 202 to move back by bouncing the mounting plate 204, so that the locking block 202 can quickly return to the initial position and no longer block the door panel 4.

[0030] Furthermore, to prevent the mounting plate 204 from disengaging from the limiting rod 208 due to excessive back movement of the locking block 202, a blocking plate 209 is provided on the outside of the limiting rod 208. The blocking plate 209 is located on the side of the mounting plate 204 away from the spring 203, and the blocking plate 209 is a rubber blocking plate. Thus, the blocking plate 209 can block the movement of the mounting plate 204, preventing the mounting plate 204 from disengaging from the limiting rod 208 due to excessive back movement of the locking block 202.

[0031] When the connecting plate 205 is pushed, the connecting plate 205 will drive the mounting bracket 206 to move laterally. The movement of the mounting bracket 206 will drive the pulley 210 to move by driving the central shaft 211. The movement of the pulley 210 will push the protrusion 207 to move laterally. The movement of the protrusion 207 will drive the locking block 202 to move, so that the locking block 202 moves quickly to the front of the door panel 4, abuts against the door panel 4, and performs a second locking on the door panel 4.

[0032] Finally, see Figure 1 , Figure 5 and Figure 6In this embodiment, the drive assembly 3 includes a rotary motor 308 and a horizontal plate 301. The rotary motor 308 is located on one side of the machine body 1. The rotary motor 308 is a bidirectional motor, and its output end can rotate forward or backward. The rotary motor 308 is used to rotate the threaded tube 302, and the rotary motor 308 can be replaced with a handle. The output end of the rotary motor 308 is key-connected to the threaded tube 302. A sleeve 303 is screwed onto the outside of the threaded tube 302. The rotation of the threaded tube 302 will drive the sleeve 303 to move linearly. A fixed shaft 304 is provided on the outside of the sleeve 303. A push plate 305 is provided on the outside of the fixed shaft 304. A moving rod 306 is slidably connected to the side of the push plate 305 away from the fixed shaft 304. The horizontal plate 301 is slidably connected to the outside of the machine body 1. 01 and two sets of connecting plates 205 are welded together. A support plate 307 is welded to one side of the horizontal plate 301. A sliding groove 309 is opened inside the support plate 307. The moving rod 306 is slidably set in the sliding groove 309. The sliding groove 309 is inclined. In order to prevent the moving rod 306 from disengaging from the sliding groove 309, two sets of discs can be set on the outside of the moving rod 306. The two sets of discs need to be located on both sides of the push plate 305 to restrict the movement of the moving rod 306 and prevent the moving rod 306 from being misaligned. A protective cover 5 is set on one side of the machine body 1. The protective cover 5 is located outside the rotary motor 308 and the threaded tube 302. Thus, the rotary motor 308 and the threaded tube 302 can be protected by the protective cover 5. When the rotary motor 308 is replaced with a handle, the handle needs to be located outside the protective cover 5.

[0033] After the rotary motor 308 is turned on, the output end of the rotary motor 308 will drive the threaded tube 302 to rotate. The rotation of the threaded tube 302 will drive the sleeve 303 to move linearly. The movement of the sleeve 303 will drive the push plate 305 to move by driving the fixed shaft 304 to move. The movement of the push plate 305 will push the moving rod 306 to move. The movement of the moving rod 306 will push the support plate 307 to move laterally. The lateral movement of the support plate 307 will drive the horizontal plate 301 to move laterally. The movement of the horizontal plate 301 will push the connecting plate 205 to move.

[0034] The mechanical locking device of the integrated distribution box, through the cooperation between the mounting bracket 206 and the protrusion 207, allows the mounting bracket 206 to move laterally by pushing the protrusion 207 when the door panel 4 needs to be fixed. After moving, the locking block 202 will abut against the door panel 4, thus locking the door panel 4 in a second way. This prevents other personnel from easily opening the door panel 4 by opening the conventional door lock, ensuring the normal work of maintenance personnel.

[0035] Working principle:

[0036] When using the integrated distribution box mechanical locking device, first place the device in the desired position. Then, during maintenance, lock the door panel 4 a second time, turn on the rotary motor 308 so that its output drives the threaded tube 302 to rotate. The rotation of the threaded tube 302 will cause the sleeve 303 to move linearly. The movement of the sleeve 303 will drive the fixed shaft 304 to move, thereby moving the push plate 305. The movement of the push plate 305 will push the moving rod 306 to move. The movement of the moving rod 306 will push the support plate 307 to move laterally. The lateral movement of the support plate 307 will drive the horizontal plate 30... 1. Lateral movement: The movement of the horizontal plate 301 will push the connecting plate 205 to move. When the connecting plate 205 is pushed, it will drive the mounting bracket 206 to move laterally. The movement of the mounting bracket 206 will drive the pulley 210 to move by driving the central shaft 211. The movement of the pulley 210 will push the protrusion 207 to move laterally. The movement of the protrusion 207 will drive the locking block 202 to move, so that the locking block 202 moves quickly to the front of the door panel 4 and abuts against the door panel 4, thus locking the door panel 4 a second time. Therefore, even if an unauthorized person opens the door panel 4 lock, the door panel 4 cannot be opened, ensuring the normal work of maintenance personnel.
