Description

Technical Field

[0001] This utility model relates to the field of electrical energy metering equipment technology, and in particular to a rail meter with a color screen. Background Technology

[0002] As a standardized modular device, the DIN rail-mounted energy meter is widely used in various terminal distribution boxes, industrial control cabinets, and building energy consumption monitoring systems due to its convenient installation and compact structure. It is an important basic component for building the sensing layer of modern smart grids.

[0003] With the deep integration of information technology and power systems, the functions of DIN rail meters are constantly evolving. To improve the efficiency of on-site human-machine interaction and the intuitiveness of data reading, the new generation of smart DIN rail meters is integrating color screens to display richer electrical parameters, waveforms, and equipment status information. Meanwhile, to meet the needs of remote data collection and IoT access, 4G and other wireless communication modules are gradually becoming standard configurations.

[0004] However, these functional upgrades also present new challenges to the structural design of electricity meters. While color screens improve display quality, they are also relatively fragile and their surfaces are easily contaminated by dust and oil in the environment. In distribution boxes with numerous meters or in harsh industrial environments, contamination or scratches on the screen can severely affect the clarity of readings and even cause the display function to fail, significantly diminishing its core advantages. Existing rail-mounted electricity meter designs primarily focus on basic installation and electrical connections, generally lacking effective protection mechanisms for such display screens.

[0005] Furthermore, the ease of installation and fine-tuning is particularly important for these more complex and valuable smart meters when installed on narrow, wired rails. Traditional snap-fit ​​structures often require tools for disassembly, making the installation process rather cumbersome, inefficient, and potentially damaging to the meter itself or nearby equipment. Current technology fails to provide a comprehensive structural solution that simultaneously satisfies the need for quick and convenient installation while effectively protecting the core display components.

[0006] Therefore, this utility model proposes a rail meter with a color screen to overcome the shortcomings of the prior art. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] Example:

[0034] Please refer to Figures 1 to 4 This utility model provides a rail-mounted electricity meter with a color screen, which aims to solve the problems of inconvenient installation and position adjustment of existing rail-mounted electricity meters, and the screen of the electricity meter is easily contaminated and damaged in dusty environments.

[0035] like Figure 1 and Figure 2 As shown, the rail-mounted meter with a color screen includes a housing 1, a control processor 11 disposed within the housing 1, and a rail mechanism 3 and a protective mechanism 4 disposed on the housing 1. The housing 1 serves as the mounting base and support platform for the entire device. A color screen 10 is provided on its outer surface, and the color screen 10 is electrically connected to the control processor 11. The housing 1 also includes voltage and current input terminals 2, an external cable temperature acquisition port 7, a communication module 8, and buttons 12. Inside the housing 1, there is a voltage transformer 5, an ultra-fast voltage adapter module 6, and a temperature acquisition terminal 9. The current input terminal 2 is electrically connected to the voltage transformer 5. The output terminal of the voltage transformer 5 is electrically connected to the input terminal of the ultra-fast voltage adapter module 6. The output terminal of the ultra-fast voltage adapter module 6 supplies power to the control processor 11. The external cable temperature acquisition port 7 is electrically connected to the temperature acquisition segment terminal 9. The signal output terminal of the temperature acquisition segment terminal 9 is electrically connected to the control processor 11. The communication module 8 and the button 12 are both electrically connected to the control processor 11. The guide rail mechanism 3 is used to quickly install the housing 1 onto the guide rail 33. The protective mechanism 4 is used to shield and protect the color screen 10.

[0036] like Figure 2 and Figure 3As shown, the guide rail mechanism 3 includes a pressing block 31 movably disposed within the housing 1, a locking block 32 fixedly connected to the pressing block 31, and the pressing block 31 protruding outward through the wall of the housing 1. A reset assembly 34 is disposed within the housing 1 and is used to apply a reset spring force to the locking block 32, making the locking block 32 suitable for detachable locking with the guide rail 33. Specifically, the reset assembly 34 includes a fixing block 342 fixed inside the housing 1 and a spring 341. One end of the spring 341 abuts against the fixing block 342, and the other end abuts against the pressing block 31. When the pressing block 31 is pressed inward, the pressing block 31 drives the locking block 32 to move into the housing 1 and compresses the spring 341, causing the locking block 32 to disengage from the guide rail 33. After the pressing block 31 is released, the rebound force of the spring 341 pushes the locking block 32 to reset and lock into the groove of the guide rail 33.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the protective mechanism 4 includes a protective cover plate 41 rotatably connected to the housing 1, a hook plate 42 fixedly connected to the outside of the protective cover plate 41, and a hook plate 43 fixedly connected to the housing 1. When the protective cover plate 41 is rotated to the closed position to cover the color screen 10, the hook plate 42 and the hook plate 43 come into contact with each other. To achieve reliable locking of the protective cover plate 41, the protective mechanism 4 also includes a fixed rod 44 rotatably connected to the housing 1, a rotating block 45 sleeved on the fixed rod 44, and a retaining ball 46 fixedly connected to one end of the rotating block 45. The outer periphery of the moving block 45 is provided with protrusions, and the hook plate 42 and hook plate 43 are provided with corresponding notches. In the assembled state, the rotating block 45 is driven to rotate around the axis of the fixed rod 44 by rotating the locking ball 46. When the rotating block 45 rotates to the locked position, the protrusions on its outer periphery are respectively engaged in the notches of hook plate 42 and hook plate 43. This rotating engagement locking structure ensures that the protective cover 41 is firmly locked in the closed position, realizing the closed protection of the color screen 10, effectively preventing dust from entering and avoiding its direct impact from the external environment.

[0038] A voltage and current input terminal 2 is fixedly connected to the housing 1. A voltage transformer 5 is fixedly installed inside the housing 1. The voltage and current input terminal 2 is electrically connected to the voltage transformer 5. An ultra-fast voltage adapter module 6 is also fixedly installed inside the housing 1. The output terminal of the voltage transformer 5 is electrically connected to the input terminal of the ultra-fast voltage adapter module 6. The output terminal of the ultra-fast voltage adapter module 6 provides operating power to the control processor 11. In order to monitor the temperature of the external cable, an external cable temperature acquisition port 7 is also fixedly installed on the housing 1. The external cable temperature acquisition port 7 is electrically connected to the temperature acquisition segment terminal 9 inside the housing 1. The signal output terminal of the temperature acquisition segment terminal 9 is electrically connected to the control processor 11. In order to realize remote data transmission and human-machine interaction, a communication module 8 is fixedly installed inside the housing 1. A button 12 is also fixedly installed on the outer surface of the housing 1. Both the communication module 8 and the button 12 are electrically connected to the control processor 11.

[0039] The working principle is as follows:

[0040] During installation or position adjustment, the operator presses the two pressing blocks 31 on the outside of the housing 1. The pressing blocks 31 move into the housing 1, which in turn drives the locking block 32, which is fixedly connected to the bottom of the pressing block 31, to move into the housing 1 in sync. The locking block 32 is a slider that matches the size of the groove in the guide rail 33. The movement of the pressing block 31 compresses the spring 341. The other end of the spring 341 is supported by the fixing block 342, which is fixed inside the housing 1. At this time, the locking block 32 disengages from the groove in the guide rail 33, allowing the entire meter housing 1 to slide freely back and forth on the guide rail 33. When the meter is adjusted to the target position, the pressing block 31 is released. Under the action of the spring 341 in the reset assembly 34, the locking block 32 is pushed back and re-locked into the newest groove in the guide rail 33, completing a quick and stable positioning installation. Through the coordinated action of the components in the guide rail mechanism 3, the problem of inconvenient installation and adjustment of existing meters is solved.

[0041] When the color screen 10 needs protection, the protective cover 41 is flipped and closed around its rotation connection point, so that the protective cover 41 covers the color screen 10. At this time, the hook plate 42 fixed to the protective cover 41 and the hook plate 43 fixed to the housing 1 come into contact with each other. Then, the operator rotates the locking ball 46, which drives the rotating block 45 to rotate around the fixed rod 44. As the rotating block 45 rotates, its outer protrusion will enter and simultaneously lock into the notches of the hook plate 42 and the hook plate 43, thereby firmly locking the two together. This achieves the sealing and fixing of the protective cover 41, effectively solving the problem of the screen being damaged or contaminated due to exposure to dusty environments.
