[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet that facilitates the rapid assembly of circuit components. Background Technology
[0002] Distribution cabinets are the final stage equipment in a power distribution system. They are suitable for situations where the load is relatively dispersed and there are few circuits. In the existing technology, distribution cabinets are mainly composed of an outer cabinet, cabinet doors, and mounting plates. During use, various lines are installed on the mounting plates and arranged separately. Then, the lines are connected to external equipment to provide power.
[0003] However, in the existing technology, the mounting plates are all designed as an integral part of the cabinet or installed inside the cabinet by fixing screws. This makes it inconvenient to adjust the position of the mounting plate and to assemble it quickly. Furthermore, it is not easy to remove individual circuit components from the mounting plate, resulting in insufficient flexibility in use.
[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a power distribution cabinet that facilitates rapid assembly of circuit components and can effectively solve these problems. Utility Model Content

The inner side of the cabinet body is provided with multiple vertically arranged mounting plates, and multiple horizontally arranged mounting seats are mounted on the mounting plates. Circuit components are fixedly mounted on the mounting seats. The mounting plates are mounted on the end face of the cabinet body via an integrated mounting assembly. The integrated mounting assembly includes two mounting frames formed in the end wall of the cabinet body. The end face of the mounting plate is formed with two sets of limiting plates, which are correspondingly engaged with the two mounting frames on both sides. The inner center of the mounting plate is open... A sliding cavity is provided, and a bidirectional threaded rod is rotatably connected between the inner walls of the two sides of the sliding cavity. Two symmetrically distributed movable plates are threadedly connected to the outer side of the bidirectional threaded rod, and a plug rod is fixedly connected to the side wall of the movable plate. The two plug rods are correspondingly inserted into two mounting frames and a limiting plate. A first bevel gear is fixedly connected to the outer wall of the bidirectional threaded rod, and a second bevel gear is meshed at one end of the first bevel gear. The second bevel gear is fixedly connected to a turntable at the outer end of the mounting plate through a connecting rod. Multiple mounting seats are installed on the front end face of the mounting plate through independent mounting components to realize the disassembly and assembly of individual circuit devices.
[0007] Preferably, the mounting frame has multiple vertically and evenly arranged insertion holes on both sides, and the edge of the insertion rod away from the moving plate is formed into a rounded corner structure.
[0008] Preferably, the rear end face of the bidirectional threaded rod is provided with a groove for the movable plate to slide through, and the distance that the movable plate can move along the groove is matched with the degree of insertion of the rod.
[0009] Preferably, the independent mounting assembly includes protruding plates formed on both sides of the mounting base. The mounting plates have cavities on both sides inside, and two guide rods are fixedly connected between the inner walls of the two sides of the cavities. Several sets of sliding blocks are slidably connected to the outer side of the guide rods, and the end of each set of sliding blocks extends through to the outer side of the mounting plate and engages with the inner side of the protruding plate of the mounting base. The end of each sliding block is formed into a hemispherical structure and engages with the end of the protruding plate of the mounting base. A first spring is fixedly connected between them. An extrusion plate is provided on the inner side of the cavity, and the bottom ends of the extrusion plate are engaged between the two sliding blocks of each set. A top rod is fixedly connected to the top of the extrusion plate, and the top rod slides through the top wall of the mounting plate.
[0010] Preferably, the two protruding plates on both sides of the mounting base are staggered in the vertical direction, that is, one is high and the other is low, and the two rods on both sides of the extrusion plate are also of different lengths.
[0011] Preferably, the top edges of the two sliding blocks in each group are rounded, and the bottom ends of both sides of the extrusion plate are formed with sharp corners in the middle.
[0012] Preferably, a second spring is fixedly connected between the top of the push rod and the top of the mounting plate on the outside of the push rod, and the second spring provides a downward pulling force to the push rod and the pressing plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This kind of power distribution cabinet that facilitates the rapid assembly of circuit devices can achieve the fixed installation of the mounting plate by setting an overall installation component and using the plug rod to be inserted into the mounting frame and the limiting plate. Moreover, by simply rotating the turntable, the plug rod can be dislodged from the mounting frame and the limiting plate by the component transmission, and then the entire mounting plate can be removed from the cabinet for easy position adjustment and rapid assembly and disassembly. At the same time, by setting an independent installation component, the disassembly and assembly of individual circuit devices can be realized, which enhances the flexibility of the device. The specific contents are as follows: (1) By setting an overall installation component, the mounting plate can be fixedly installed by using two plug rods to be inserted into the mounting frame and the limiting plate. When disassembling, simply rotate the turntable and use the second bevel gear, the first bevel gear, the bidirectional threaded rod, and the moving plate in sequence to dislodge the plug rod from the mounting frame and the limiting plate. At this time, the entire mounting plate can be removed from the cabinet, which facilitates position adjustment and rapid assembly and disassembly.
[0014] (2) By setting up an independent installation component, the hemispherical shape formed at the end of the sliding block is separated by the extrusion plate, so that this part can be firmly attached to the end face of the protrusion plate to fix the mounting seat. When disassembly is required, simply move the top rod up to make the extrusion plate disengage from the sliding block. The first spring rebounds and drives the sliding block to come closer and fit. The protrusion plate of the mounting seat can then be easily disassembled, thus realizing quick disassembly of the mounting seat and greatly enhancing the flexibility of use.
[0015] (3) By staggering the distribution of the mounting plate protrusions, not only will the balance of the two sides of the mounting plate be not affected, but the horizontal installation space of the mounting plate can also be saved, so that the end face of the mounting plate can accommodate more mounting plates. Furthermore, the different lengths of the rods on both sides of the pressing plate allow their bottom ends to be correspondingly engaged between two sets of sliding blocks of different heights.
[0016] (4) The second spring between the top rod and the mounting plate provides a downward pulling force to the top rod and the pressing plate, so that the bottom sides of the pressing plate can be firmly inserted between each set of sliding blocks, thereby further ensuring the installation stability of the mounting base.

Detailed Implementation
[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] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a power distribution cabinet that facilitates rapid assembly of circuit components, comprising a cabinet body 1 and a cabinet door 2. Multiple vertically arranged mounting plates 3 are provided on the inner side of the cabinet body 1, and multiple horizontally arranged mounting seats 4 are mounted on the mounting plates 3. Circuit components are fixedly mounted on the mounting seats 4. The mounting plates 3 are mounted on the end face of the cabinet body 1 via an integrated mounting assembly. The integrated mounting assembly includes two mounting frames 5 formed on the end wall of the cabinet body 1. Two sets of limiting plates 6 are formed on the end face of the mounting plates 3, and the two sets of limiting plates 6 are correspondingly engaged with the two sides of the two mounting frames 5. A sliding cavity 7 is provided in the middle of the inner side of the mounting plate 3, and a bidirectional threaded rod 8 is rotatably connected between the inner walls of the two sides of the sliding cavity 7. Two symmetrically distributed movable plates 9 are threadedly connected to the outer side of the bidirectional threaded rod 8, and a plug rod 10 is fixedly connected to the side wall of the movable plate 9. The two plug rods 10 are correspondingly inserted into the two mounting frames 5 and the limiting plate 6. A first bevel gear 11 is fixedly connected to the outer wall of the bidirectional threaded rod 8, and a second bevel gear 12 is meshed at one end of the first bevel gear 11. The second bevel gear 12 is fixedly connected to the turntable 13 at the outer end of the mounting plate 3 through a connecting rod.
[0026] By setting up an overall installation assembly, the mounting plate 3 can be fixedly installed by inserting two plug rods 10 into the mounting frame 5 and the limiting plate 6. The mounting frame 5 has multiple vertically evenly arranged insertion holes on both sides, and the end wall edge of the plug rod 10 away from the moving plate 9 is formed with a rounded corner structure. By inserting the plug rod 10 into the insertion holes of different heights, the mounting plate 3 can be fixed at different heights on the mounting frame 5. The rounded corner edge of the plug rod 10 guides its smooth insertion into the insertion hole. During disassembly, simply rotating the turntable 13 drives the second bevel gear 12 to rotate synchronously. The second bevel gear 12 then drives the meshing first bevel gear 11 to rotate, and subsequently, the bidirectional threaded rod 8 rotates synchronously. Rotating the rod causes the two movable plates 9 on the outer side of the bidirectional threaded rod 8 to move closer together, and the insertion rod 10 will disengage from the mounting frame 5 and the limiting plate 6. At this point, the mounting plate 3 can be completely removed from the cabinet 1. The rear end face of the bidirectional threaded rod 8 is provided with a sliding groove for the movable plate 9 to slide through. The distance that the movable plate 9 can move along the sliding groove is matched with the length of the insertion rod 10. Through the setting of the sliding groove, the movable plate 9 can be limited to horizontal movement, and the sliding distance of the movable plate 9 is set so that the insertion rod 10 can be completely disengaged from the mounting frame 5 and the limiting plate 6, so as to realize the convenient disassembly of the mounting plate 3, which facilitates its position adjustment and quick assembly and disassembly, greatly enhancing its flexibility of use.
[0027] Example 2: Based on Example 1, multiple mounting bases 4 are mounted on the front end face of the mounting plate 3 via independent mounting components to achieve the disassembly and assembly of individual circuit devices. Specifically, the independent mounting components include protruding plates formed on both sides of the mounting base 4. Cavities are formed on both sides of the interior of the mounting plate 3, and two guide rods 14 are fixedly connected between the inner walls of the two sides of the cavities. Several sets of sliding blocks 15 are slidably connected to the outer sides of the guide rods 14, and the end of each set of sliding blocks 15 extends through to the outer side of the mounting plate 3 and engages with the inner side of the protruding plate of the mounting base 4. The end of the sliding block 15 is formed into a hemispherical structure, and the hemisphere engages with the end of the protruding plate of the mounting base 4, with a first spring 16 fixedly connected between them. An extrusion plate 17 is provided on the inner side of the mounting plate 17, and the bottom ends of the extrusion plate 17 are engaged between two sliding blocks 15 in each group. The two protrusions on both sides of the mounting base 4 are staggered in the vertical direction, i.e., one is high and the other is low. The two rods on both sides of the extrusion plate 17 are also of different lengths. By staggering the protrusions of the mounting base 4, the balance of the two sides of the mounting base 4 is not affected, and the horizontal installation space of the mounting base 4 is saved, so that the end face of the mounting plate 3 can accommodate more mounting bases 4. The different lengths of the two rods on both sides of the extrusion plate 17 allow its bottom ends to be engaged between two groups of sliding blocks 15 with different heights. The top end of the extrusion plate 17 is fixedly connected to a top rod 18, and the top rod 18 slides through the top wall of the mounting plate 3.
[0028] The bottom ends of the extrusion plate 17 are engaged with the two sliding blocks 15 in each group, keeping them separated. The hemispherical tops of the sliding blocks 15 are securely engaged with the end face of the convex plate of the mounting base 4, thus fixing the mounting base 4 in place. Furthermore, the adjacent top edges of the two sliding blocks 15 in each group are rounded, and both bottom ends of the extrusion plate 17 have sharp corners in the center. Through the cooperation between the sharp corners of the extrusion plate 17 and the rounded edges of the sliding blocks 15, the extrusion plate 17 can smoothly push the two sliding blocks 15 apart when it descends, achieving a rapid limiting effect on the convex plate of the mounting base 4. Additionally, the top of the push rod 18 and the top of the mounting plate 3... A second spring 19 is fixedly connected to the outside of the top rod 18, and the second spring 19 provides a downward pulling force to the top rod 18 and the pressing plate 17, so that the bottom sides of the pressing plate 17 can be firmly inserted between each set of sliding blocks 15, thereby further ensuring the installation stability of the mounting base 4. When disassembly is required, simply move the top rod 18 upward to drive the pressing plate 17 to move synchronously, and the bottom of the pressing plate 17 will disengage between the two sliding blocks 15. At this time, under the rebound of the first spring 16, the two sliding blocks 15 approach and fit together, and the convex plate of the mounting base 4 can be disengaged through the hemispherical part of the sliding block 15, thus realizing the quick disassembly of the mounting base 4.
