Technical Field

[0001] This utility model relates to the technical field of distribution boxes, specifically to an easy-to-disassemble mounting base for a low-voltage integrated distribution box. Background Technology

[0002] Integrated distribution boxes, also known as JP cabinets, are a type of distribution cabinet. Distribution cabinets are low-voltage power distribution devices formed by assembling switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, circuits can be cut off or alarms can be triggered by protective electrical appliances. Measuring instruments can display various parameters during operation, and certain electrical parameters can be adjusted. The system can also provide prompts or signals for deviations from normal operating conditions.

[0003] Chinese patent CN213636777U discloses an easily detachable distribution box, comprising a hollow base with a distribution box mounting seat at the center of the top of the hollow base; a first slider is slidably connected to the inner cavity of a first hollow vertical plate, a first electric cylinder is located at the center of the outer wall of the first hollow vertical plate facing the distribution box, and a second electric cylinder is located below the first electric cylinder on the outer wall of the first hollow vertical plate; a second slider is slidably connected to the inner cavity of a second hollow vertical plate, a third electric cylinder is located at the center of the outer wall of the second hollow vertical plate facing the distribution box, and a fourth electric cylinder is located below the third electric cylinder on the outer wall of the second hollow vertical plate; a first servo motor and a second servo motor are fixed to the bottom sides of the inner cavity of the hollow base respectively, a first fan is fixed to the top of the inner cavity of the hollow base near the first servo motor, and a second fan is fixed to the top of the hollow base near the second servo motor.

[0004] In the above solution, the four corners of the distribution box are fastened to the top surface of the hollow base with screws, which has the following disadvantages: when the distribution box is transported or needs to be repaired due to failure, it needs to be manually disassembled and reassembled from the mounting base with the help of tools, which is cumbersome and wastes labor and time. Utility Model Content

[0005] The purpose of this utility model is to provide an easy-to-disassemble mounting base for a low-voltage integrated distribution box, so as to solve the problem that when the distribution box needs to be transported or repaired due to malfunction, it is necessary to manually disassemble and install it from the mounting base with the help of tools, which is a cumbersome operation and wastes labor and time costs.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an easy-to-disassemble mounting base for a low-voltage integrated distribution box, comprising a load-bearing plate, the load-bearing plate being fixed to the bottom surface of the distribution box body, two mounting base bodies being provided on the bottom surface of the load-bearing plate, two positioning holes being provided on the mounting base bodies, a plurality of receiving grooves being provided on the bottom surface of the load-bearing plate, the mounting base bodies being inserted into the receiving grooves, two L-shaped grooves being provided on both the left and right sides of the load-bearing plate, the L-shaped grooves being connected to the receiving grooves, mounting grooves being provided on both the left and right sides of the inner wall of the L-shaped grooves, a limiting block being inserted into the inner wall of the mounting groove, an L-shaped limiting rod being slidably connected to the inner wall of the L-shaped groove, the L-shaped limiting rod being inserted into the positioning hole, and two limiting frames being provided on the outer wall of the L-shaped limiting rod, the left limiting frame being fixed to the outer wall of the L-shaped limiting rod, and the right limiting frame being slidably connected to the outer wall of the L-shaped limiting rod.

[0007] Preferably, protective plates are rotatably connected to both the left and right sides of the load-bearing plate via hinges.

[0008] Preferably, an elastic gasket is fixed to the bottom surface of the mounting base body, and a plurality of through holes are opened on the inner wall of the mounting base body. A fixing bolt is inserted into the inner wall of the through hole, and the fixing bolt passes through the elastic gasket.

[0009] Preferably, two support blocks are fixed on the top surface of the mounting base body.

[0010] Preferably, the top surface of the load-bearing plate has two strip-shaped holes, the bottom surface of the distribution box body has several water outlet holes corresponding to the strip-shaped holes, and the left and right side plates of the distribution box body each have several ventilation holes, and the two sides of the two side plates that are close to each other are connected with a baffle plate by screws.

[0011] Preferably, a fixing hole is provided on the left side plate, and a fan is fixed to the inner wall of the fixing hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated action of the limiting block, L-shaped limiting rod, and limiting frame, the mounting base body achieves multi-directional limiting and self-locking functions, allowing for convenient assembly and disassembly without tools, saving labor and time costs, and further reducing the space occupied by the distribution box and mounting base body during transportation, thereby improving the usability of the mounting base body. The protective plate protects the two L-shaped limiting rods, effectively preventing displacement due to external impacts and avoiding detachment of the mounting base body from the bottom of the load-bearing plate, thus improving the practicality of the protective plate.

[0014] Second, the elastic gaskets absorb vibrations from equipment operation or external sources, effectively maintaining the preload of the fixing bolts and preventing them from loosening. The triangular structure of the support block increases the stability of the mounting base, effectively preventing deformation caused by lateral shear forces, reducing local stress concentration, and thus ensuring the stability of the distribution box during operation.

[0015] Third, the baffle plate can block rainwater (especially during heavy rain or strong winds) from entering the distribution box, guiding the water droplets to the drainage holes on the bottom of the box for discharge. This effectively prevents splashing rainwater from affecting the equipment and extends its service life. The fan accelerates air circulation within the distribution box, allowing heat generated by the equipment to escape through the ventilation holes, preventing overheating-related malfunctions or shortened lifespan.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, an easy-to-disassemble mounting base for a low-voltage integrated distribution box includes a load-bearing plate 1, which is fixed to the bottom surface of the distribution box body 2. Two mounting base bodies 3 are provided on the bottom surface of the load-bearing plate 1. Two positioning holes 4 are provided on the mounting base bodies 3. Several receiving grooves 5 are provided on the bottom surface of the load-bearing plate 1, and the mounting base bodies 3 are inserted into the receiving grooves 5. Two L-shaped grooves 6 are provided on both the left and right sides of the load-bearing plate 1, and the L-shaped grooves 6 are connected to the receiving grooves 5. Mounting grooves 7 are provided on both the left and right sides of the wall. Limiting blocks 8 are inserted into the inner wall of the mounting grooves 7. An L-shaped limiting rod 9 is slidably connected to the inner wall of the L-shaped groove 6. The L-shaped limiting rod 9 is inserted into the positioning hole 4. Two limiting frames 10 are provided on the outer wall of the L-shaped limiting rod 9. The left limiting frame 10 is fixed to the outer wall of the L-shaped limiting rod 9, and the right limiting frame 10 is slidably connected to the outer wall of the L-shaped limiting rod 9. Protective plates 12 are rotatably connected to both the left and right sides of the load-bearing plate 1 via hinges.

[0023] During use, when it is necessary to disassemble the mounting base body 3, the operator can first open the protective plate 12, and then apply opposing forces to the two L-shaped limiting rods 9, driving the sliding limiting frame 10 to move towards the receiving groove 5. Under continuous force, the inclined surface of the fixed limiting frame 10 contacts the limiting block 8, compressing the spring to retract it into the mounting groove 7. Thus, the sliding limiting frame 10 will move to the side of the limiting block 8 without an inclined surface under the obstruction of the L-shaped limiting rods 9. At this time, the force is continuously applied. The sliding limit frame 10 is brought into contact with the fixed limit frame 10 by passing the inclined side of the limit block 8 and positioning it to the side without the inclined side. At this time, the spring releases its potential energy, pushes the limit block 8 to reset, and locks into the side edge of the sliding limit frame 10. At the same time, the operator can apply the same force to the two L-shaped limit rods 9. The inclined surface of the sliding limit frame 10 forces the limit block 8 to retract twice, releasing the constraint on the fixed limit frame 10, so that the L-shaped limit rods 9 are disengaged from the positioning hole 4, thereby completing the disassembly of the mounting base body 3.

[0024] When the mounting base body 3 needs to be installed, the mounting base body 3 can be inserted into the receiving groove 5 on the bottom surface of the load-bearing plate 1, ensuring that the positioning hole 4 is axially aligned with the L-shaped limiting rod 9. Then, the L-shaped limiting rod 9 is moved in the opposite direction, and its fixed limiting frame 10 presses the inclined surface of the limiting block 8, causing the limiting block 8 to retract into the mounting groove 7. The L-shaped limiting rod 9 is continuously pushed until it is fully inserted into the positioning hole 4, thus achieving the initial limiting of the mounting base body 3. When the fixed limiting frame 10 slides to the side of the limiting block 8 without the inclined surface, the spring drives the limiting block 8 to pop out, forming mechanical interference with the outer wall of the L-shaped limiting rod 9, preventing axial displacement, and then closing the protective plate 12 to complete the rigid fixing of the mounting base body 3.

[0025] Through the coordinated action of the limiting block 8, the L-shaped limiting rod 9, and the limiting frame 10, the multi-directional limiting and self-locking functions of the mounting base body 3 are achieved. This allows the mounting base body 3 to be easily disassembled and assembled without tools, saving labor and time costs, and further saving the space occupied by the distribution box body 2 and the mounting base body 3 during transportation, thereby improving the usability of the mounting base body 3. The protective plate 12 can protect the two L-shaped limiting rods 9, effectively preventing the L-shaped limiting rods 9 from displacement due to external force collisions, and preventing the mounting base body 3 from detaching from the bottom surface of the load-bearing plate 1, thereby improving the practicality of the protective plate 12.

[0026] like Figures 1-3 As shown, an elastic pad 13 is fixed on the bottom surface of the mounting base body 3, and several through holes 14 are opened on the inner wall of the mounting base body 3. Fixing bolts 15 are inserted into the inner wall of the through holes 14, and the fixing bolts 15 pass through the elastic pad 13. Two support blocks 16 are fixed on the top surface of the mounting base body 3.

[0027] During use, the elastic gasket 13 absorbs vibrations from equipment operation or external sources, effectively maintaining the preload of the fixing bolt 15 and preventing it from loosening. The triangular structure of the support block 16 increases the stability of the mounting base body 3, effectively preventing deformation caused by lateral shear forces, reducing local stress concentration, and thus ensuring the stability of the distribution box body 2 during operation.

[0028] like Figures 1-4 As shown, the top surface of the load-bearing plate 1 has two strip holes 17, the bottom surface of the distribution box body 2 has several water outlet holes 18, the water outlet holes 18 correspond to the strip holes 17, the left and right side plates of the distribution box body 2 each have several ventilation holes 19, the two sides of the two side plates that are close to each other are connected with a baffle plate 20 by screws, the left side plate has a fixing hole 21, and the inner wall of the fixing hole 21 is fixed with a fan 22.

[0029] During use, the baffle plate 20 can block rainwater (especially during heavy rain or strong winds) from entering the distribution box body 2, allowing the rainwater to flow through the baffle plate 20 and be discharged through the water outlet 18 on the bottom surface of the distribution box body 2. This effectively prevents splashing rainwater from affecting the equipment and extends its service life. The fan 22 can accelerate the air circulation inside the distribution box body 2, allowing the heat generated by the equipment in the distribution box body 2 to be discharged through the ventilation hole 19, preventing the equipment from malfunctioning or having its lifespan shortened due to overheating.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
