Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a modular power distribution cabinet. Background Technology

[0002] A distribution cabinet is an integrated power device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet. It can be customized to meet the needs of a power system, achieving specific electrical functions. Depending on different application scenarios and functional requirements, distribution cabinets can be categorized into various types.

[0003] Currently, in practical applications, power distribution cabinets are often placed side by side at the installation site. However, with prolonged use, some power distribution cabinets may shift, affecting the reasonable spacing between the cabinets and thus the heat dissipation effect. This results in uneven placement of the cabinets, which not only affects the aesthetics but also increases the difficulty of later maintenance.

[0004] Among them, Chinese patent document CN211126569U discloses "a modular small power distribution cabinet", which includes "a base fixedly installed on the side wall of the power distribution cabinet, an installation groove opened on the side wall of the base, a crossbar snapped in the installation groove, the crossbars of two horizontally adjacent power distribution cabinets are connected by a connector, a positioning block is provided on the top of the power distribution cabinet, a positioning groove is provided on the bottom of the power distribution cabinet, and two vertically adjacent power distribution cabinets are engaged by the positioning block and the positioning groove". It realizes the splicing function of the cabinet through components such as crossbars, anti-detachment blocks, and anti-detachment grooves. However, in actual application, its splicing component structure is relatively complex, making the overall splicing process cumbersome and unable to achieve rapid splicing. Therefore, there is an urgent need for a modular power distribution cabinet. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular power distribution cabinet.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular power distribution cabinet includes a cabinet body. On opposite sides of the cabinet body, there are two splicing blocks, namely a first splicing block and a second splicing block. The middle of the second splicing block is connected to a docking frame via a pivot. A docking rod is symmetrically provided at one end of the docking frame. A protruding ring is provided at one end of the docking rod, and a locking ring is screwed to the side away from the protruding ring via a threaded wall.

[0008] The splicing block and the connecting rod are a splicing structure that connects with each other. The middle part of the splicing block is provided with a snap-fit ​​groove to connect with the protruding ring. When two adjacent cabinets are spliced, the connecting rod and the splicing block are connected to each other, and the protruding ring on one side of the connecting rod is fitted into the snap-fit ​​groove.

[0009] In addition, a preferred structure is that the middle part of one side of the docking frame is rotatably connected to the splicing block two, and a torsion spring is provided at the rotatable connection between the docking frame and the splicing block two.

[0010] Furthermore, in a preferred configuration, the torsion spring generates a torsional force that always deflects downwards, and the connecting frame is naturally attached to the outer wall of the distribution cabinet via the torsion spring.

[0011] In addition, a preferred structure is that an arc-shaped groove is provided in the middle of one side of the snap-fit ​​groove, and the arc-shaped groove is used to mate and fit the mating rod.

[0012] In addition, a preferred structure is that a certain gap is left between the convex ring and the locking ring.

[0013] Furthermore, in a preferred configuration, the outer diameter of the locking ring is larger than the inner diameter of the arc-shaped groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this utility model, a flip-up docking frame is provided on one side of the cabinet, and a docking rod is provided on the docking frame. The docking rod and the splicing block one provided on the other side of the cabinet are docking mechanisms to realize the splicing function of adjacent cabinets. Furthermore, a snap-fit ​​groove and an arc groove are provided in the middle of the splicing block one to fit the protruding ring and locking ring assembly provided on the docking rod, which effectively improves the splicing stability. Moreover, the entire splicing process is convenient and fast, effectively improving the splicing efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A modular power distribution cabinet includes a cabinet body 1. On opposite sides of the cabinet body 1, there are a pair of splicing blocks 1 2 and splicing blocks 2 5 respectively. The middle of the splicing blocks 2 5 is connected to a docking frame 8 through a rotating shaft. A docking rod 3 is symmetrically arranged at one end of the docking frame 8. A protruding ring 4 is provided at one end of the docking rod 3. A locking ring 41 is screwed to the side away from the protruding ring 4 through a threaded wall 42.

[0023] The splicing block 2 and the connecting rod 3 are a splicing structure that connects with each other. The middle part of the splicing block 2 has a snap-fit ​​groove 6 to connect with the protruding ring 4. When two adjacent cabinets are spliced, the connecting rod 3 and the splicing block 2 are connected to each other, and the protruding ring 4 on one side of the connecting rod 3 is fitted and snapped into the snap-fit ​​groove 6.

[0024] The middle of one side of the docking frame 8 is rotatably connected to the splicing block 2 5, and a torsion spring 7 is provided at the rotatable connection between the docking frame 8 and the splicing block 2 5. The torsion spring 7 generates a torsional force that always deflects downward. The docking frame 8 is naturally attached to the outer wall of the distribution cabinet 1 through the torsion spring 7. When the docking rod 3 is docked with the splicing block 1 2, the torsional force generated by the torsion spring 7 can ensure that the docking rod 3 is stably engaged in the splicing block 1 2.

[0025] An arc-shaped groove 61 is provided in the middle of one side of the snap-fit ​​groove 6. The arc-shaped groove 61 is used to mate with the mating rod 3, thereby improving the connection stability.

[0026] A certain gap is left between the convex ring 4 and the locking ring 41. The gap is used to connect the arc groove 61. At the same time, the outer diameter of the locking ring 41 is larger than the inner diameter of the arc groove 61.

[0027] In this embodiment, when two adjacent distribution cabinets 1 are connected, the docking frame 8 set on one side of the distribution cabinet 1 is flipped and made to be horizontal. At the same time, during the rotation, the protruding ring 4 set at the end of the docking rod 3 is aligned and snapped into the splicing block 5 of the other cabinet to be connected. The snapping groove 6 opened in the middle of the splicing block 5 aligns with the protruding ring 4. At the same time, the docking rod 3 is fitted and connected by the arc groove 61. Under the torsion action of the torsion spring 7, the docking rod 3 is stably snapped into the splicing block 2. Then, by rotating the locking ring 41, its thread rotates and moves, gradually cooperating with the locking ring 4 to lock the entire splicing block 2, thereby improving the connection stability.

[0028] The process involves simply rotating the connecting rod 3 and engaging it with the splicing block 2 on the adjacent cabinet. The splicing block 2 is equipped with a snap-fit ​​groove and an arc groove to improve the snap-fit ​​efficiency, and the locking ring 41 ensures the stability of the snap-fit. The entire splicing process is fast, convenient, and stable.

[0029] It is worth noting that the internal electrical components, wiring harnesses, and installation methods of the distribution cabinet 1 are common knowledge to those skilled in the art, and will not be elaborated further here unless otherwise explained above.

[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.
