Description

Technical Field

[0001] This utility model relates to the field of power equipment enclosure technology, and in particular to an electric meter box with a layered cable fixing bracket. Background Technology

[0002] As an indispensable terminal device in power systems, the main function of the meter box is to provide a safe and stable operating environment for core electrical components such as electricity meters, circuit breakers, and capacitors. In traditional meter box designs, internal components are usually fixed to the mounting plate one by one using bolts or clips, and the connecting cables are simply bundled or placed in cable trays.

[0003] With the increasing complexity and intelligence of electricity demands, modern meter boxes need to accommodate a growing number of components, and their functions are becoming increasingly integrated. This has led to an exceptionally crowded interior space and a significantly higher density of components. Under this high-density layout, the traditional installation method of relying on bolts to tighten each component individually is particularly inefficient, not only consuming a significant amount of installation and debugging time, but also causing considerable inconvenience during subsequent maintenance or component replacement.

[0004] Even more seriously, a large number of cables are tangled and mixed in confined spaces, with high-voltage cables and low-voltage signal cables often laid out closely in parallel. This disordered wiring not only makes fault diagnosis difficult, but also causes severe signal interference between high-voltage and low-voltage cables due to electromagnetic induction, affecting the accuracy of metering data and the stability of control signals, thus posing a safety hazard to the reliable operation of the entire power system.

[0005] Therefore, this utility model proposes an electric meter box with a layered cable fixing bracket to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a meter box with a layered cable fixing bracket, which aims to improve the problems of cumbersome and time-consuming installation of internal components, chaotic cable arrangement and easy signal interference in the existing meter box.

[0011] Preferably, one end of the rotating rod abuts against the threaded rod, and the other end is fixedly connected to the movable plate, and the rotating rod is slidably connected to the fixed plate.

[0012] Preferably, a second rotating shaft is rotatably connected to the bottom of the movable plate, a movable component is fixedly connected to one side of the movable plate, and a sliding groove is provided on the inner plate for the movable component to slide.

[0022] 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.

[0023] Reference Figures 1-5 This utility model provides an equipment box with a cable layer fixing bracket, which aims to solve the problems of complicated installation of internal components, messy cable arrangement and easy signal interference in the prior art.

[0024] like Figure 1 and Figure 2As shown, the equipment box with cable layer fixing rack includes a box body 1 and an inner plate 7 fixedly connected inside the box body 1. A display 3 is fixedly installed on the outside of the box body 1. A box door 4 for closing the box body 1 is rotatably connected to one side of the box body 1, and an observation door 2 is rotatably connected to the other side. The inner plate 7 serves as an installation reference for installing quick-release components 5 and clamping components 8. The quick-release assembly 5 is used to quickly fix the capacitor 6. The quick-release assembly 5 includes a first rotating shaft 502 rotatably connected to the inner plate 7, a fixing frame 501 fixedly connected to the first rotating shaft 502, and a locking strip 503 fixedly connected to the fixing frame 501. The inner wall shape of the fixing frame 501 is adapted to the outer wall shape of the capacitor 6. A locking block 505 is slidably provided on the inner plate 7. A spring 504 is connected between the locking block 505 and the inner plate 7. The spring 504 is used to push the locking block 505 to reset after the locking strip 503 is inserted to lock the locking strip 503. The clamping assembly 8 is used to separate and fix the cable of the capacitor 6. The clamping assembly 8 includes a fixed plate 802 fixedly connected to the inner plate 7 and a movable plate 807 slidably connected to the inner plate 7. The movable plate 807 is arranged parallel to the fixed plate 802. Deformable parts 804 are fixedly connected to opposite sides of the fixed plate 802 and the movable plate 807. The clamping assembly 8 also includes a driving mechanism, which includes a handle 801 rotatably passing through the housing 1 and a screw threadedly connected to the inner wall of the housing 1 and coaxially fixedly connected to the handle 801. The moving plate 807 is driven by the threaded rod 805 and the rotating rod 803 is driven by the threaded rod 805 to push the moving plate 807. One end of the rotating rod 803 abuts against the threaded rod 805 and the other end is fixedly connected to the moving plate 807. The rotating rod 803 is slidably connected to the fixed plate 802. To ensure the stability of the movement of the moving plate 807, a second rotating shaft 808 is rotatably connected to the bottom of the moving plate 807. A moving part 806 is also fixedly connected to one side of the moving plate 807. A sliding groove for the moving part 806 to slide is correspondingly opened on the inner plate 7.

[0025] Reference Figure 3 and Figure 5 The first pivot 502 of the quick-release assembly 5 is rotatably connected to the inner plate 7, the fixed frame 501 is fixedly connected to the first pivot 502, and the locking strip 503 is fixedly connected to the fixed frame 501, so that the fixed frame 501 and the locking strip 503 can rotate synchronously around the first pivot 502. The inner plate 7 is provided with a slot for the locking strip 503 to be inserted. The locking block 505 is slidably disposed on the inner plate 7 and adjacent to the slot. One end of the spring 504 is connected to the locking block 505, and the other end is connected to the inner plate 7. When installing capacitor 6, first place capacitor 6 inside fixed frame 501, then rotate fixed frame 501. The rotation of fixed frame 501 drives the locking strip 503 into the slot of inner plate 7. During the entry process, the end of locking strip 503 pushes open locking block 505 and compresses spring 504. After locking strip 503 passes locking block 505, the compressed spring 504 rebounds, pushing locking block 505 to reset and engage at the notch of locking strip 503. This cooperation structure formed by rotating part and rebound self-locking part ensures that capacitor 6 can be installed firmly without the use of additional tools, which greatly improves assembly efficiency and ensures the reliability of connection.

[0026] In a preferred embodiment, in order to clarify the driving connection relationship of the clamping assembly 8, one end of the rotating rod 803 abuts against the end of the threaded rod 805, and the other end is fixedly connected to the moving plate 807, and the rotating rod 803 is slidably connected to the fixed plate 802. As another preferred embodiment, in order to further improve the stability of the moving plate 807 during movement, a second rotating shaft 808 is rotatably connected to the bottom of the moving plate 807, and a moving part 806 is fixedly connected to the side of the moving plate 807 away from the fixed plate 802. A sliding groove is correspondingly provided on the inner plate 7 for the moving part 806 to slide. The cooperation between the moving part 806 and the sliding groove plays a precise guiding and limiting role in the movement path of the moving plate 807. As a specific application, the fixing frame 501 is used to accommodate and fix the capacitor 6. The inner wall of the fixing frame 501 is configured to match the outer wall contour of the capacitor 6 to ensure a tight fit. In addition, to improve the overall function of the enclosure 1, a door 4 is connected to one side of the enclosure 1 by a hinge, and an observation door 2 is also connected to the other side of the enclosure 1 by a hinge. A display 3 is also fixedly installed on the outer wall of the enclosure 1.

[0027] Working principle: When installing capacitor 6, first place capacitor 6 inside the fixed frame 501 in the open state, then rotate the fixed frame 501. The fixed frame 501 rotates around the first rotating shaft 502, and drives the fixedly connected locking strip 503 to rotate synchronously, so that the locking strip 503 is inserted into the preset slot of the inner plate 7. During the insertion of the locking strip 503, its end will push the locking block 505, so that the locking block 505 overcomes the elastic force of the spring 504 and slides to make way for the locking strip 503. When the locking strip 503 is fully inserted into the slot, the elastic force of the spring 504 pushes the locking block 505 to spring back and reset, and lock into the notch of the locking strip 503, thereby realizing the quick and stable locking of capacitor 6. The whole process does not require any additional tools and is easy to operate. When organizing the cables, first, the cable of capacitor 6 is passed through the inner plate 7 and placed between the deformable parts 804 of the fixed plate 802 and the movable plate 807. Then, the handle 801 on the outside of the box 1 is rotated. The handle 801 drives the threaded rod 805, which is fixedly connected to it on the same axis, to rotate. Since the threaded rod 805 is threadedly connected to the inner wall of the box 1, the threaded rod 805 will generate linear displacement while rotating, and push the rotating rod 803 that is in contact with it to move. The rotating rod 803 then drives the movable plate 807, which is fixedly connected to it, to slide towards the fixed plate 802. During this process, the movable part 806 slides in the sliding groove of the inner plate 7, providing guidance for the smooth movement of the movable plate 807. As the distance between the movable plate 807 and the fixed plate 802 decreases, the deformable parts 804 on both will clamp the cable, thereby realizing the separation, organization and fixation of the cable, effectively solving the problems of messy cables and signal interference.
