[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet structure. Background Art

[0002] The distribution cabinet is an important facility in the circuit system, which plays an important role in the normal operation of the circuit system. However, the existing distribution cabinets are often stolen, especially those used in remote areas or outdoors. If the distribution cabinet is stolen, it will not only affect its use but also cause great losses.

[0003] Distribution cabinets generally use mechanical locks as an anti-theft method. The lock core and lock body materials of mechanical locks are often difficult to resist violent destruction. Thieves can easily destroy the mechanical lock structure with tools such as crowbars. The connection between the door and the cabinet body is also easily deformed and damaged under strong prying, and it cannot form an effective protective barrier. Once the door is pried open, the internal circuit breakers, relays, cables and other electrical equipment will be exposed without protection, allowing thieves to steal, causing the power system to be paralyzed. The repair is difficult and time-consuming, affecting the reliability and safety of the power supply. To this end, we propose a distribution cabinet structure. Summary of the Invention

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0018] Example 1 See also Figures 1-13 , the present invention provides a technical solution: A distribution cabinet structure includes a cabinet body 1 and a cabinet door 2 hinged to the cabinet body 1 by a hinge, a protective unit 3 is provided on one side of the cabinet door 2, the protective unit 3 includes a reinforcing plate 4 provided on the cabinet door 2, and the reinforcing plate 4 is set as a cavity structure, the four corners of the cabinet door 2 are fixedly connected with relative splints 6, the splint 6 is set as an elastic structure, the four corners of one side of the reinforcing plate 4 are provided with sockets 7 adapted to the shape of the splint 6, a trigger mechanism 8 is provided in the cavity of the reinforcing plate 4, and a locking mechanism 9 is provided on the trigger mechanism 8, the cabinet body 1 is provided with evenly distributed movable grooves 39, the movable grooves 39 are provided with movable parts 37, the movable parts 37 include slide rails 43 provided in the movable grooves 39, a slider 40 is slidably installed on the slide rail 43, the slider 40 is provided with a docking groove 41 adapted to the shape of the locking block 38, and a spring rod 42 is symmetrically fixedly connected between the docking groove 41 and the movable groove 39.

[0019] The trigger mechanism 8 includes a protective sleeve 22 arranged on the four corners of one side of the cavity of the reinforcing plate 4, a connecting rod 21 is slidably inserted in the protective sleeve 22, a second return spring 35 is sleeved on the connecting rod 21, a clamped block 20 is provided at one end of the connecting rod 21, and the clamped block 20 is tightly against the clamping plate 6, and the other end of the connecting rod 21 is fixedly connected to the push plate 13, and the push plate 13 forms a forward stroke after being triggered to drive the locking mechanism 9 to form a lock between the movable sleeve 37 and the reinforcing plate 4.

[0020] The locking mechanism 9 includes an insertion shaft 15 inserted in the cavity of the reinforcing plate 4, and a double-bulge turntable 12 is rotatably installed on one end of the insertion shaft 15. An insertion block 36 is fixedly connected to the two bumps of the double-bulge turntable 12, and a movable block 25 is slidably installed in the cavity of the reinforcing plate 4. A locking block 38 is symmetrically provided on one side of the movable block 25, and the locking block 38 slides in a clamping sleeve 24 provided in the cavity of the reinforcing plate 4. A rectangular hole 26 that is adapted to the shape of the insertion block 36 is opened on the movable block 25, and the insertion block 36 is inserted into the rectangular hole 26 and slidably assembled. A gear 16 is rotatably installed on the insertion shaft 15, and the gear 16 and the double-bulge turntable 12 are movably matched. A fixed frame 14 is fixedly connected to one side of the push plate 13, and a rack 19 is fixedly connected to the fixed frame 14, and the rack 19 is meshed with the gear 16.

[0021] When the second return spring 35 is pressed against the locking mechanism 9, the locking mechanism 9 is released, and the locking mechanism 9 is locked. When movement occurs, the rack 19 meshes with the gear 16, and the driving gear 16 starts to rotate. The rotation of the gear 16 drives the double-bump turntable 12 to rotate together. The insert block 36 on the double-bump turntable 12 slides in the rectangular hole 26 of the movable block 25, pushing the movable block 25 to move outward, and finally the locking block 38 on one side of the movable block 25 is inserted into the movable part 37 in the cabinet body 1, realizing the mechanical locking between the movable part 37 and the reinforcing plate 4. After the locking block 38 is inserted into the docking groove 41, the reinforcing plate 4 can replace the cabinet door 2. Continue to close the cabinet body 1. Since the reinforcing plate 4 and the slider 40 maintain a rigid connection, when the demolition worker uses a tool to pry up the reinforcing plate 4, the force will push the reinforcing plate 4 backward, making it impossible for the demolition worker to find a force point and pry up the reinforcing plate 4. Even if the reinforcing plate 4 is pushed to the back, the prying tool fits the inner wall of the cabinet body 1 and can only pry up the edge of the reinforcing plate 4 vertically, and cannot form an effective force arm. Therefore, it is difficult to damage the surface of the reinforcing plate 4, preventing the cabinet door 2 from being further opened, and effectively resisting demolition.

[0022] The trigger mechanisms 8 at the four corners of the cabinet door work together to form multiple trigger points. When any corner of the cabinet door is deformed, the lock is activated, which can ensure stable triggering and effectively resist malicious demolition. After the protective unit 3 and the cabinet body 1 are locked, even if the demolition user removes the entire cabinet door 2, the protective unit 3 can replace the cabinet door 2 to continue to close the cabinet body 1. When the demolition user uses a tool to pry up the reinforcement plate 4, the force will push the reinforcement plate 4 to move backward, making it impossible for the demolition user to find a force point and pry up the reinforcement plate 4. Even if the reinforcement plate 4 is pushed to the back, the prying tool fits the inner wall of the cabinet body 1 and can only pry up the edge of the reinforcement plate 4 vertically, and cannot form an effective force arm. Therefore, it is difficult to destroy, and the user can only choose a cutting tool with louder noise. The cabinet is broken into by cutting, which has a greater risk of breaking. The protection unit 3 is hidden in the cabinet door structure and does not affect the appearance of the distribution cabinet. It is difficult for the demolisher to detect it in advance, which ensures the protection effect. The locking block 38 is extended based on the restoring elastic force of the second reset spring 35. There is an obvious impact sound when inserted into the movable part 37, and it can also be observed from the outside of the cabinet door, which can form an effective deterrent to the destroyer. Through the mechanical trigger structure 8 and the mechanical locking mechanism 9, the structure is reliable, the service life is long, the maintenance is simple, and the safety is high. The reinforcement plate 4 is attached to the cabinet door 2, and can also enhance the rigidity of the cabinet door 2 and reduce deformation. There is no need to set a rack 19 and a gear 16 for each trigger point, which reduces the number of parts and reduces the complexity of the structure.

[0023] Example 2 See also Figure 5 、 Figure 6 and Figure 12 , the present invention provides a technical solution: A push block 17 is fixedly connected to one side of the gear 16, and a contact block 18 is symmetrically fixedly connected to one side of the double-block turntable 12, and the contact block 18 abuts against the push block 17. During use, when the breaker pries a corner of the cabinet door 2, the trigger mechanism 8 is triggered, and the push plate 13 drives the rack 19 to move, thereby driving the gear 16 to rotate. When the gear 16 rotates, the pushing block 17 thereon rotates accordingly. When the pushing block 17 contacts the contact block 18 on the double-bump turntable 12, it pushes the contact block 18, thereby driving the double-bump turntable 12 to rotate, realizing the linkage between the double-bump turntable 12 and the gear 16, and finally causing the locking block 38 to insert into the movable part 37 to complete the locking. Since the contact block 18 is rigidly connected to the double-bump turntable 12, when a single pushing block 17 pushes the contact block 18, it can drive the double-bump turntable 12 and all the pushing blocks 17 to move together. This design enables the trigger point on one side to drive the double-bump turntable 12 to rotate alone without affecting the locking status of the other trigger points.

[0024] The difference from Example 1 is that when the demolition worker pries up a corner to trigger the lock, if the demolition worker is frightened and flees, the maintenance personnel only need to restore the clamped block 20 on the side corresponding to the pried up corner when restoring the position of the clamped block 20, and there is no need to operate other untriggered trigger points, which reduces the workload of the maintenance personnel and makes maintenance easier.

[0025] Example 3 See also Figure 3 、 Figure 4 、 Figure 8 and Figure 11 , the present invention provides a technical solution: An adjustment hole 5 is provided on the outer wall of the reinforcement plate 4, and an unlocking mechanism 27 is provided in the cavity of the reinforcement plate 4, and the unlocking mechanism 27 is movably coordinated with the double-bump turntable 12. During use, when it is necessary to open the locked cabinet door 2, the maintenance personnel use a specially equipped key to insert the adjustment hole 5 and cooperate with the unlocking mechanism 27. By turning the key, the unlocking mechanism 27 rotates in the opposite direction, and the unlocking mechanism 27 drives the double-bump turntable 12 to rotate in the opposite direction, thereby causing the insertion block 36 to push the movable block 25 in the opposite direction, and retract the locking block 38 from the movable part 37, thereby releasing the locked state of the reinforcement plate 4 and the cabinet body 1, making it convenient for maintenance personnel to inspect and maintain the internal equipment of the distribution cabinet.

[0026] Different from Example 1, since a separate unlocking mechanism 27 and key are provided, only maintenance personnel with a special key can release the locked state, thereby improving safety and confidentiality, so that maintenance personnel can quickly release the lock when necessary to inspect and maintain the distribution cabinet, thereby improving work efficiency.

[0027] Example 4 See also Figure 8 、 Figure 9 and Figure 11 , the present invention provides a technical solution: A single cam turntable 28 is provided on the unlocking mechanism 27, a limit block 31 is fixedly connected to the cavity of the reinforcing plate 4, a push rod 30 is slidably inserted in the limit block 31, a first return spring 32 is sleeved on the push rod 30, an arc block 29 and a piston rod 11 are respectively provided at both ends of the push rod 30, and the arc block 29 abuts against the single cam turntable 28, an oil storage box 10 is provided in the cavity of the reinforcing plate 4, and the piston rod 11 is slidably inserted into the oil storage box 10, and an oil pipe 23 is connected between the output port of the oil storage box 10 and the clamping sleeve 24. When in use, when the maintenance personnel use the key to rotate the unlocking mechanism 27 to unlock, The unlocking mechanism 27 drives the single cam turntable 28 to rotate synchronously. As the single cam turntable 28 rotates, its cam profile pushes the arc block 29 in contact with it, causing the push rod 30 to overcome the elastic force of the first return spring 32 and slide along the limit block 31. The piston rod 11 at one end of the push rod 30 compresses the grease in the oil storage box 10. The compressed grease is transported to the clamping sleeve 24 through the oil pipe 23, forming a lubricating film on the surface of the locking block 38. When the unlocking is completed, the first return spring 32 pushes the push rod 30 to reset, and the oil storage box 10 automatically replenishes grease through the one-way valve, preparing for the next unlocking operation.

[0028] Different from Example 3, lubrication is automatically provided to components such as the locking block 38 and the clamping sleeve 24 during the unlocking process, which reduces the friction resistance when the locking block 38 slides, making the unlocking operation easier and more labor-saving, and reducing the workload of maintenance personnel. At the same time, the presence of the lubricating film reduces the wear between components and extends the service life of components such as the locking block 38 and the clamping sleeve 24, thereby reducing the frequency of manual maintenance, reducing maintenance costs and manpower investment, and improving the overall economy and practicality of the anti-theft structure of the distribution cabinet.

[0029] Example 5 See also Figures 1-4 , the present invention provides a technical solution: The protection unit 3 is fixed to the cabinet door 2 by at least one of magnetic attraction, bolt connection and suction cup adsorption. During use, when the distribution cabinet door 2 is made of metal, the protection unit 3 can be installed by magnetic attraction, and the magnetic parts and magnetic conductive parts are respectively installed on the protection unit 3 and the cabinet door 2. The installation is quickly completed by using the magnetic attraction force, and when disassembling, it is only necessary to overcome the magnetic attraction force to easily remove it without tools. If the material of the cabinet door 2 is suitable for punching, a bolt connection method can be used to firmly fix the protection unit 3 on the cabinet door 2 by bolts to ensure the stability of the protection unit 3 during use. When disassembly is required, the bolts can be unscrewed using tools such as a screwdriver. For some cabinet door 2 materials that cannot be punched and have a flat surface, a suction cup adsorption method can be used. The vacuum suction cup and the surface of the cabinet door 2 are formed with a vacuum device to achieve negative pressure, thereby realizing the installation of the protection unit 3. When disassembling, it is only necessary to release the negative pressure in the vacuum suction cup to quickly remove it.

[0030] Different from Example 1, the setting of multiple fixing methods allows the protection unit 3 to flexibly choose the installation method according to the material of the cabinet door 2 such as metal and the usage scenario, which has a wide range of applicability. No tools are required or only simple tools are needed for quick completion during disassembly, highlighting the convenience of disassembly. At the same time, after disassembly, the protection unit 3 and the cabinet door 2 have no permanent damage and can be reinstalled and used, meeting the requirements of detachable and reusable, reducing the cost of use and improving resource utilization.

[0031] Example 6 See also Figure 8 、 Figure 9 、 Figure 11 and Figure 13 , the present invention provides a technical solution: When the lock mechanism 27 is unlocked, the push plate 13 is driven by the gear 19 to move, and the gear 16 and the double-bump turntable 12 are driven to rotate.

[0032] Different from Example 3, by providing a one-way rotation mechanism 34, the motion interference between the trigger mechanism 8 and the unlocking mechanism 27 during the working process is effectively avoided, thereby ensuring the independence and stability of the locking mechanism 9 and the unlocking mechanism 27, improving the reliability and safety of the entire anti-theft structure, reducing the probability of failure due to mechanism interference, and reducing maintenance costs and difficulty.

[0033] Example 7 See also Figure 1 and Figure 14 , the present invention provides a technical solution: The cabinet body 1 adopts a layered skeleton structure, including multiple independent functional layers, each layer is connected by a skeleton structure, and the skeleton structure is a frame made of metal profiles.

[0034] During use, during the manufacturing process of the distribution cabinet, each functional layer can be manufactured separately and then assembled and connected through the skeleton structure. Compared with the traditional integral cabinet, the construction period is shortened and the production efficiency is improved. During transportation, since each functional layer is independent of each other, it is convenient to transport and carry, which reduces the difficulty and cost of transportation. At the installation site, the installer can quickly and conveniently install each functional layer in place according to actual needs and layout, thereby improving the installation efficiency. When the equipment in a functional layer inside the distribution cabinet fails, the maintenance personnel can quickly locate the functional layer where the fault is located and remove the faulty functional layer separately for inspection or replacement. There is no need to dismantle the entire distribution cabinet on a large scale, which reduces the time and scope of power outages, reduces the losses caused by power outages, and improves power supply reliability.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0036] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
