Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet assembly technology, and in particular relates to an assembly structure for a row of air switches. Background Technology

[0002] Electrical component assembly in a distribution cabinet refers to the process of rationally installing and connecting various electrical components, such as circuit breakers, contactors, relays, fuses, and metering instruments, into the distribution cabinet according to electrical design requirements and relevant standards and specifications, using specific processes and technologies, to build a complete and reliable electrical control system.

[0003] During the assembly process, air switches located in distribution cabinets are usually installed one by one inside the cabinet. Due to the relatively small space inside the distribution cabinet and the limited operating space, it is difficult for installers to operate inside the cabinet. Moreover, the operation in the confined space can easily lead to installers accidentally touching other installed electrical components, causing misalignment. Therefore, there is a need to provide an air switch assembly structure that adopts an external assembly and overall relocation method into the cabinet. This facilitates the assembly of air switches and has a secondary installation and locking method to ensure the installation is secure. Utility Model Content

[0013] In the following description, embodiments of the air switch assembly structure of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates an embodiment of an air switch assembly structure, comprising multiple mounting rails 2 distributed on the rear side of the inner cavity of a distribution cabinet 1. Multiple air switches 3 are fastened to the surface of the mounting rails 2. Positioning seats 4 are welded to both ends of the mounting rails 2. A locking assembly 5 is provided within the inner cavity of the positioning seat 4. The locking assembly 5 includes a limiting plate 51 extending from the top to the bottom of the positioning seat 4, which is slidably connected to the inner cavity of the positioning seat 4. A protective cover 8 is rotatably connected to the top of the inner cavity of the positioning seat 4, covering the surface of a nut 55. An elastic clip 9 is integrally molded at the bottom of the protective cover 8. A rectangular slot 10 is provided at the bottom of the inner cavity of the positioning seat 4, and the elastic clip 9 is fastened into the inner cavity of the rectangular slot 10. Through the combined use of the protective cover 8, the elastic clip 9, and the rectangular slot 10, the threaded head 54 and the nut 55 are shielded and protected, thereby reducing the possibility of corrosion at the threaded head 54 and extending its service life. For ease of subsequent assembly and disassembly, a large circular hole 52 is provided on the front side of the limiting plate 51, and a rectangular through hole 6 is provided on the top of the front side of the limiting plate 51. A spring 7 is welded to the top of the inner cavity of the rectangular through hole 6, and the bottom end of the spring 7 is welded to the positioning seat 4. A small circular hole 56 is provided at the bottom of the inner cavity of the large circular hole 52 and communicates with it. The small circular hole 56 is fitted onto the surface of the threaded head 54. Through the setting of the small circular hole 56, the limiting plate 51 can be fitted onto the rear side of the surface of the threaded head 54, aligning with the positioning seat 4. The base 4 is temporarily fixed to facilitate the user's subsequent alignment and installation of the nut 55. At the same time, the mounting rail 2 after the air switch 3 is assembled has a large self-weight. The small round hole 56 is fitted on the surface of the threaded head 54, which can effectively prevent the mounting rail 2 from falling off. A welding plate 53 is welded to the rear side of the inner cavity of the distribution cabinet 1. A threaded head 54 is welded to the front side of the welding plate 53. A nut 55 is threadedly connected to the surface of the threaded head 54. The nut 55 is pressed onto the surface of the limit plate 51.

[0015] Working principle: When using this utility model, the user pre-attaches the air switch 3 to the surface of the mounting rail 2 and electrically connects multiple air switches 3 to be connected via wires. Then, the user simultaneously presses down on the two limit plates 51 with both hands. The limit plates 51 slide downwards, causing the large round hole 52 to move down, and the spring 7 is compressed. The user then pushes the mounting rail 2 from the front to the rear of the inner cavity of the distribution cabinet 1, so that the threaded head 54 passes through the inner cavity of the large round hole 52 until the rear of the positioning seat 4 is in contact with the front of the welding plate 53. At this time, the user releases the limit plates 51, and the compressed spring 7 rebounds and pushes the limit plates 51. Sliding upwards, the limiting insert 51 causes the small round hole 56 to engage with the surface of the threaded head 54 during the upward sliding process, temporarily limiting and fixing the mounting guide rail 2. Then, the user puts the nut 55 into the inner cavity of the positioning seat 4 and screws it onto the surface of the threaded head 54 with a wrench, causing the nut 55 to rotate and push backwards, finally squeezing the inner wall of the limiting insert 51 and the positioning seat 4, so that the mounting guide rail 2 can be installed stably. Finally, the user rotates the protective cover 8, so that the elastic clip 9 engages in the inner cavity of the rectangular slot 10 after deformation, limiting and fixing the protective cover 8. The threaded head 54 and the nut 55 are protected by the protective cover 8.

[0016] In summary, this air switch assembly structure, through the installation guide rail 2, allows multiple air switches 3 to be assembled and fixed outside the cabinet. Subsequently, with the cooperation of the positioning seat 4 and the locking component 5, the installation guide rail 2 with the air switches 3 is stably and quickly fixed to the rear side of the inner cavity of the distribution cabinet 1, thus achieving the purpose of large-space assembly outside the cabinet and secondary installation and locking.
