[0001] This utility model relates to the field of power time-sharing control host, and in particular to a power time-sharing control host that is easy to maintain. Background Technology

[0002] As the core equipment for power distribution and timing control, the power time-sharing control host is widely used in industrial production lines, smart buildings, data centers and other scenarios. By precisely controlling the power supply periods of different loads, it achieves optimized allocation of power resources and reduced energy consumption, ensuring the orderly operation of various electrical equipment.

[0003] These main units integrate precision circuit components such as controllers, relays, and terminals. The stable operation of these components directly determines the control accuracy and service life of the main unit. Therefore, during long-term use, it is necessary to regularly inspect and maintain the internal components to troubleshoot circuit faults, clean dust accumulation, and replace aging parts to ensure the continuous and reliable operation of the main unit.

[0004] However, conventional power time-sharing control hosts are inadequate in terms of maintenance convenience. Most hosts adopt an integrated enclosed shell design, and multiple sets of bolts on the shell must be removed before the components can be accessed. The installation and removal of bolts require alignment with the threaded holes and the use of tools, making the operation steps cumbersome and somewhat limited, thus resulting in poor convenience. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a power time-sharing control host that is easy to maintain. It aims to improve the problems of conventional power time-sharing control hosts in the prior art, which use an integrated enclosed shell, require disassembly of multiple sets of bolts and tools for maintenance, resulting in cumbersome operation, great limitations and poor convenience.

Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-2This utility model provides an embodiment of a power time-sharing control host that is easy to maintain, including a mounting frame 1, which serves as the core supporting frame of the entire power time-sharing control host and mainly provides support for various components. A protective component 4 is provided at the top of the mounting frame 1, and a mounting plate 5 is slidably connected to the inner wall of the mounting frame 1. The mounting plate 5 is the mounting carrier for the internal circuit components of the power time-sharing control host, and its function is to concentrate and fix the scattered components, which facilitates the orderly layout of the components and the connection of the circuit. A pull ring 6 is fixedly connected to the bottom of the front surface of the mounting plate 5. When it is necessary to maintain the internal components, the maintenance personnel can pull the mounting plate 5 out of the mounting frame 1 by pulling the pull ring 6. When resetting, the position of the mounting plate 5 can also be controlled by the pull ring 6. A disassembly and assembly component 7 is provided inside the mounting frame 1.

[0020] Reference Figures 3-5 The assembly / disassembly component 7 includes a limiting groove 71, which is formed on the left and right sides of the mounting plate 5. The inner wall of the mounting bracket 1 is elastically connected to a connecting plate 76 via an elastic element 77, which is used to connect the stop block 75, the elastic element 77 and the limiting block 78. The connecting plate 76 is fixedly connected to the limiting block 78 on the side near the center of the mounting bracket 1. The limiting groove 71 and the limiting block 78 fit together, and the edge of the limiting groove 71 is chamfered to facilitate the alignment of the limiting block 78. The two cooperate with each other to limit the mounting plate 5.

[0021] Reference Figure 2 , Figure 6 , Figure 7 The disassembly and assembly component 7 also includes a stop block 75, which is fixedly connected to the side of the connecting plate 76 near the center of the mounting bracket 1. A connecting block 73 is slidably connected through the lower surface of the mounting bracket 1 to transmit the operating force of the lever 72. A pressing member 74 is fixedly connected to the upper surface of the connecting block 73, and a lever 72 is fixedly connected to the lower surface of the connecting block 73. As a manual control component for unlocking the disassembly and assembly component 7, its main function is to provide maintenance personnel with a convenient point of force. When the mounting plate 5 needs to be pulled out, the maintenance personnel can move the lever 72 to drive the connecting block 73 and the pressing member 74 to move laterally, thereby pushing the stop block 75 and the connecting plate 76, so that the limiting block 78 disengages from the limiting groove 71, thereby unlocking the mounting plate 5. When the two sets of levers 72 are unlocked, they need to move in opposite directions to avoid accidental contact that could cause slippage.

[0022] Reference Figure 2 , Figure 3 , Figure 6 Support pads 3 are fixedly connected to the four corners of the lower surface of the mounting bracket 1. The support pads 3 are made of wear-resistant plastic, which makes it easy to place the mounting bracket 1 directly. Mounting ears 2 are fixedly connected to the left and right ends of the front surface of the mounting bracket 1 to realize the fixed connection between the mounting bracket 1 and the external mounting carrier. Bolt holes are reserved on them. By passing the bolts through the mounting ears 2, the mounting bracket 1 can be firmly fixed in the target position. Common mounting carriers include equipment brackets.

[0023] Reference Figure 1 , Figure 8 The mounting bracket 1 has grooves on both the left and right ends of its inner surface, and the mounting plate 5 has protrusions on both the left and right ends. The protrusions are slidably connected to the inner wall of the grooves. The cross-sections of the grooves and protrusions from front to back are all dovetail-shaped. The grooves can guide the protrusions and prevent the parts from slipping off. The grooves penetrate the front surface of the mounting bracket 1.

[0024] Reference Figure 2 , Figure 3 , Figure 6 The connecting plate 76 is slidably connected to the inner wall of the mounting frame 1. One end of the elastic element 77 is fixedly connected to the side of the connecting plate 76 near the center of the mounting frame 1, and the other end of the elastic element 77 is fixedly connected to the side of the mounting frame 1 near its own center. When the connecting plate 76 moves toward the edge of the mounting frame 1, it will stretch the elastic element 77 to generate a reaction force. The side of the limiting block 78 near the center of the mounting frame 1 is set to gradually tilt away from the center of the mounting frame 1 from front to back. The limiting block 78 is inserted into the inner wall of the limiting groove 71. When the mounting plate 5 moves backward and slides into the mounting frame 1, it will squeeze the inclined surface of the limiting block 78. The side of the stop block 75 near the center of the mounting frame 1 is set to gradually tilt away from the center from front to back. Gradually tilting towards the center of the mounting frame 1, when the inclined surface is squeezed, it will drive the connecting plate 76 to move away from the center of the mounting frame 1. Multiple sets of limiting grooves 71, connecting plates 76, elastic elements 77, and limiting blocks 78 are provided. The multiple sets of limiting grooves 71, connecting plates 76, elastic elements 77, and limiting blocks 78 are symmetrically distributed on the left and right with the center line of the mounting frame 1 as the axis. Two sets of levers 72, connecting blocks 73, squeezing elements 74, and stop blocks 75 are provided. The two sets of levers 72, connecting blocks 73, squeezing elements 74, and stop blocks 75 are centrally symmetrically distributed with the center point of the mounting frame 1 as the origin. The levers 72 need to be moved in two opposite directions to release the limit.

[0025] Reference Figures 1-2 The protective component 4 includes a protective cover 41, which is used to protect the components inside the mounting bracket 1. The protective cover 41 is sleeved on the top of the outer wall of the mounting bracket 1. Mounting holes 43 are provided on both the left and right sides of the mounting bracket 1. Fixing members 42 are inserted into both the left and right sides of the protective cover 41. The fixing members 42 are bolts. The fixing members 42 are fixedly installed on the inner wall of the mounting holes 43. The bolts and the mounting holes 43 are threaded together.

[0026] Working principle: When the device is in normal use, the mounting frame 1 is fixed to the external carrier through the mounting ears 2. In the protective component 4, the protective cover 41 is sleeved on the top of the mounting frame 1. The fastener 42 is screwed into the mounting hole 43 to fix the protective cover 41, preventing dust and liquid from entering the interior of the mounting frame 1 and protecting the circuit components on the mounting plate 5.

[0027] Mounting plate 5 slides into the interior along the dovetail groove of mounting frame 1 via the left and right protrusions. When sliding, the side of mounting plate 5 presses against the inclined surface of limiting block 78, pushing connecting plate 76 to move towards the edge of mounting frame 1 and stretching elastic element 77. When mounting plate 5 is pushed to the designated position, limiting groove 71 aligns with limiting block 78, elastic element 77 releases its elastic force to drive connecting plate 76 to reset, so that limiting block 78 is inserted into limiting groove 71, completing the locking and fixing of mounting plate 5 and ensuring stable operation of components.

[0028] When maintenance is required, move the two sets of levers 72 in opposite directions. Lever 72 drives the connecting block 73 to move laterally, causing the pressing component 74 to move synchronously and press the inclined surface of the stop block 75. After the stop block 75 is under force, it drives the connecting plate 76 to move away from the center of the mounting frame 1, while stretching the elastic component 77, causing the limiting block 78 to disengage from the limiting groove 71 and releasing the locking of the mounting plate 5. At this time, the maintenance personnel can pull the pull ring 6 to pull the mounting plate 5 out of the mounting frame 1 through the protrusion along the slide groove, and directly inspect the components on the mounting plate 5. After the inspection is completed, push the mounting plate 5 back to the slide groove and repeat the locking steps to re-fix it. The entire process does not require disassembling the main unit, improving the convenience of maintenance.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
