Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a modularly installed power distribution cabinet. Background Technology
[0002] A distribution cabinet is an electrical device used for centralized installation, distribution and control of electrical energy. It is widely used in industrial, commercial and residential power systems. It typically contains electrical components such as circuit breakers, contactors and relays. Through reasonable layout and wiring, it realizes circuit protection, monitoring and power distribution.
[0003] Currently, standardized guide rails are typically used inside distribution cabinets to install various electrical control devices, such as circuit breakers and power modules. In traditional installation methods, the guide rails need to be bolted to the brackets or backplate inside the cabinet during the initial assembly of the distribution cabinet to ensure its stability.
[0004] Although bolted connections can securely fix the guide rails, in small distribution cabinets or compact cabinets, the internal space is limited, making it difficult for installers to use tools to tighten the bolts. This not only increases the difficulty of installation but may also lead to a decrease in installation accuracy due to insufficient operating space, affecting the convenience of later maintenance. Therefore, a modular installation distribution cabinet is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a modularly installed power distribution cabinet, which aims to improve the problem mentioned in the prior art that "it is inconvenient to install guide rails in small power distribution cabinets or compact cabinets".

[0014] As a further description of the above technical solution:
[0015] The cabinet has ventilation holes on both the left and right sides.
[0016] As a further description of the above technical solution:
[0017] One end of the spring is fixedly connected to the side wall of the card block, and the other end of the spring is fixedly connected to the inner wall of the mounting module.
[0018] As a further description of the above technical solution:
[0019] The L-rod is slidably connected to the inner wall of the mounting module, and the outer wall of the L-rod is attached to the inner wall of the inclined groove.
[0020] As a further description of the above technical solution:
[0021] The inner side of the card block fits against the outer wall of the guide rail, thus fixing the guide rail to the outer wall of the mounting module.

[0033] 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.
[0034] Reference Figures 1-3 This utility model provides an embodiment of a modularly installed power distribution cabinet, including a cabinet body 1. An installation module 2 is slidably connected to the inner wall of the cabinet body 1. The installation module 2 can be used to fix the guide rail 3 in a modular installation manner, and the guide rail 3 can be fixed inside the cabinet body 1 without the aid of tools. The outer wall of the installation module 2 is snapped with the guide rail 3. An installation mechanism 4 is provided inside the installation module 2. A positioning mechanism 5 is provided inside the cabinet body 1. Heat dissipation holes 6 are provided on both the left and right sides of the cabinet body 1, and the heat dissipation holes 6 can be used to dissipate the heat inside the cabinet body 1 to the outside.
[0035] Reference Figures 3-5 The installation mechanism 4 includes a locking block 41, which is slidably connected to the inner wall of the installation module 2. The inner side of the locking block 41 is in contact with the outer wall of the guide rail 3, so that the guide rail 3 is fixed to the outer wall of the installation module 2. The guide rail 3 can be fixed to the side wall of the installation module 2 by the limiting of the locking block 41, thereby completing the installation of the guide rail 3. The inner wall of the installation module 2 is slidably connected to a sliding plate 44, which has a sloping groove 45. The side wall of the locking block 41 is fixedly connected to an L-rod 42. When the L-rod 42 slides, it will drive the locking block 41 to move synchronously. The L-rod 42 is slidably connected to the inner wall of the installation module 2, and the outer wall of the L-rod 42 is in contact with the inner wall of the sloping groove 45. The sliding of the sliding plate 44 and the sloping groove 45 can drive the L-rod 42 to slide on the inner wall of the installation module 2.
[0036] Reference Figure 4 and Figure 6 A spring 43 is fitted on the outer wall of the L-rod 42. One end of the spring 43 is fixedly connected to the side wall of the locking block 41, and the other end of the spring 43 is fixedly connected to the inner wall of the mounting module 2. The elasticity of the spring 43 can drive the locking block 41 to slide and reset on the inner wall of the mounting module 2.
[0037] Reference Figures 2-4 The positioning mechanism 5 includes a column 51, which is fixedly connected to the inner wall of the cabinet 1. The column 51, in conjunction with the positioning groove 52, can support the positioning block 53. The column 51 has equidistantly arranged positioning grooves 52 along its axial direction. The positioning grooves 52 can limit the positioning block 53 inside the column 51. The end of the L-rod 42 away from the locking block 41 is fixedly connected to the positioning block 53, which meshes with the positioning groove 52. When the positioning block 53 is limited, it can limit the height of the installation module 2 in conjunction with the L-rod 42.
[0038] Working principle: When the guide rail 3 needs to be installed inside the cabinet 1, first push the slide plate 44 downwards so that it slides down the inner wall of the mounting module 2. As the slide plate 44 slides downwards, the inclined groove 45 will squeeze the L-rod 42, causing the L-rod 42 to slide on the inner wall of the mounting module 2. At the same time, the L-rod 42 will drive the locking block 41 to slide on the inner wall of the mounting module 2 and stretch the spring 43. At this time, the two sets of locking blocks 41 inside the mounting module 2 will move synchronously in opposite directions and move away from each other. Then, fasten the guide rail 3 to the side wall of the mounting module 2, and then release the slide plate 44. Plate 44 prevents the inclined groove 45 from pressing the L-rod 42, thus preventing the L-rod 42 from pushing the locking block 41. At this time, the spring 43 will pull the locking block 41 to slide and reset on the inner wall of the mounting module 2. At this time, the two sets of locking blocks 41 inside the mounting module 2 will move towards each other, so that the inner side of the locking block 41 can fit against the outer wall of the guide rail 3. Under the limiting action of the locking block 41, the guide rail 3 can be fixed to the outer wall of the mounting module 2, thus completing the installation of the guide rail 3. The guide rail 3 can be fixed inside the cabinet 1 without the aid of tools, making it more convenient to use.
[0039] Before installing the guide rail 3, if it is necessary to adjust the installation height of the guide rail 3, first push the sliding plate 44 downwards, so that the sliding plate 44 slides downwards on the inner wall of the mounting module 2. At the same time, the inclined groove 45 will squeeze the L-rod 42, so that the L-rod 42 slides on the inner wall of the mounting module 2. At this time, the L-rod 42 will drive the positioning block 53 to gradually move out of the inside of the positioning groove 52. After the positioning block 53 is completely removed from the inside of the positioning groove 52, the mounting module 2 can be pushed up and down, so that the mounting module 2 slides up and down on the inner wall of the cabinet 1. This allows adjustment of the height of the mounting module 2 or adjustment of the distance between two adjacent sets of mounting modules 2. After adjustment, push the slide plate 44 upward to make it slide upward on the inner wall of the mounting module 2. As the slide plate 44 slides upward, the inclined groove 45 will squeeze the L rod 42, causing the L rod 42 to slide on the inner wall of the mounting module 2. At this time, the L rod 42 will drive the positioning block 53 to re-insert into the positioning groove 52. The positioning groove 52 can then limit the positioning block 53 inside the column 51. At the same time, the L rod 42 can limit the height of the mounting module 2, thereby fixing the height of the installed guide rail 3. This allows the height of the guide rail 3 to be freely adjusted according to the actual installation situation, improving the flexibility of the cabinet 1.
[0040] 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.
