Description

Technical Field

[0001] This utility model relates to the field of ring main unit cabinet door technology, and in particular to a ring main unit cabinet door structure that is easy to open and close. Background Technology

[0002] Network cabinets are core equipment in power distribution networks, used for 10-20kV line ring network power supply and terminal power distribution. They integrate switches, protection and metering components, are small in size and highly reliable, and are widely used in residential communities, industrial parks and other scenarios. Their cabinet door structure controls the opening and closing of the front of the cabinet, and the main cabinet door is equipped with an observation window to check the status of the internal equipment.

[0003] Existing ring main unit (RMU) cabinet doors mostly adopt a traditional outward-opening structure. While this achieves basic opening and closing functions, it still has significant shortcomings: First, the door needs to unfold outwards after opening, which can easily obstruct the front maintenance area of ​​the cabinet, resulting in limited space for maintenance and adjustment of internal electrical components; second, the outward-opening door lacks a storage and protection structure, making it susceptible to damage from handling equipment, shaking during rotation and installation, and collisions with personnel in industrial settings, posing a risk of personnel injury. Therefore, those skilled in the art have provided a ring main unit cabinet door structure that facilitates opening and closing to solve the problems mentioned in the background art. Utility Model Content

[0004] Technical solution

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a ring main unit door structure that facilitates opening and closing, comprising: Cabinet body, cabinet door one and cabinet door two located at the front of the cabinet body; The storage structure includes grooves on the outer walls of both sides of the cabinet, storage slots inside both ends of the cabinet and passing through the grooves, sliders slidably installed inside the grooves, mounting seats symmetrically distributed at one end of the sliders, a rotating shaft rotatably installed inside the mounting seat (207), a center block located at one end of cabinet door one and cabinet door two and connected to the outer wall of the rotating shaft, and a torsion spring sleeved on the outside of the rotating shaft and connected at both ends to the mounting seat and the center block. as well as; The fixed structure includes a docking groove opened inside the front end of cabinet door one and a docking box embedded inside the front end of cabinet door two.

[0006] Furthermore, an installation box is provided inside the rear side of the cabinet, and an installation shaft is rotatably installed inside the installation box. A disc spring with one end connected to the installation box is sleeved on the outer wall of the installation shaft, and a pull rope with one end connected to the slider is wound on the outer wall of the installation shaft. Specifically, when the shaft rotates, it winds up and unwinds the pull rope, while simultaneously tightening or resetting the coil spring, causing the pull rope to be affected by the elastic force of the coil spring itself.

[0007] Furthermore, the slide groove has a travel hole that penetrates the interior of the cabinet, and the pull rope is slidably installed inside the travel hole; Specifically, the pull rope slides effectively inside the cabinet through the travel hole.

[0008] Furthermore, the outer wall of the mounting shaft is fitted with symmetrically distributed limiting rings located on the upper and lower sides of the pull rope, the opening of the slide groove is provided with a limiting block one located on the sliding path of the slider, and a limiting block two is provided between the mounting seats; Specifically, the limiting ring limits the pull rope of the winding, and the limiting block pair limits the slider to prevent the slider from completely leaving the groove. When the rotating shaft drives the center block to rotate, the center block rotates to the limit block two and is intercepted. At this time, cabinet door one and cabinet door two rotate with the rotating shaft to correspond to the storage groove.

[0009] Furthermore, a slot is provided inside the upper end of the docking groove, and a positioning rod inserted into the slot is slidably installed inside the upper end of the docking box. A support ring is sleeved on the outer wall of the positioning rod, and a spring connected to the lower inner wall of the docking box is provided at the lower end of the support ring. Specifically, after the upper end of the positioning rod is inserted into the slot, cabinet door one and cabinet door two are closed, and the positioning rod is supported by the elastic force of the spring.

[0010] Furthermore, a travel groove is provided inside the front end of the docking box, and a handle connected to the support ring is slidably installed inside the travel groove. A positioning cylinder located inside the lower end of the docking box is provided inside the spring and slidably sleeved on the outer wall of the lower end of the positioning rod. Specifically, when the spring extends or retracts, the lower end of the positioning rod slides inside the positioning cylinder, limiting the spring and preventing it from shifting outward. At the same time, the gripping handle slides inside the front end of the docking box through the stroke groove, effectively applying longitudinal force to the positioning rod and opening and closing cabinet door one and cabinet door two. Beneficial effects

[0011] Compared with existing technologies, the advantages of this utility model are: In this invention, cabinet doors one and two rotate within the mounting base via a pivot, enabling opening and closing operations at the front of the cabinet. During use, the pivot, connected to a slider, receives torsional elastic support via a torsion spring. When cabinet door one or cabinet door two rotates to the corresponding storage slot via the pivot, the slider slides within the slot, and cabinet doors one and two follow the slider into the storage slot. The storage slots are located on both sides of the cabinet, with the cabinet doors positioned on either side of the cabinet after opening. This design prevents the cabinet doors from obstructing operation during the inspection, adjustment, and maintenance of electrical components inside the ring main unit, expanding the operating space. Furthermore, the opened cabinet door structure is less susceptible to impact damage, enhancing both convenience and safety.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example

[0020] Please see Figure 1-7 As shown, this embodiment is a ring main unit door structure that is easy to open and close, including: Cabinet 100, cabinet door 101 and cabinet door 2 102 located at the front end of cabinet 100; The storage structure 200 includes a slide groove 201 formed on the outer walls of both sides of the cabinet 100, a storage slot 202 formed inside both ends of the cabinet 100 and passing through the slide groove 201, a slider 203 slidably installed inside the slide groove 201, a mounting base 207 symmetrically distributed at one end of the slider 203, a rotating shaft 208 rotatably installed inside the mounting base 207, a center block 209 located at one end of cabinet door 101 and cabinet door 202 and connected to the outer wall of the rotating shaft 208, and a torsion spring 210 sleeved on the outside of the rotating shaft 208 and connected at both ends to the mounting base 207 and the center block 209. An installation box 204 is provided inside the rear side of the cabinet 100. An installation shaft 213 is rotatably installed inside the installation box 204. A coil spring 212 with one end connected to the installation box 204 is sleeved on the outer wall of the rotating shaft 208. A pull rope 205 with one end connected to the slider 203 is wound on the outer wall of the installation shaft 213. The slide 201 has a travel hole 211 that penetrates the interior of the cabinet 100, and the pull rope 205 is slidably installed inside the travel hole 211; The outer wall of the mounting shaft 213 is fitted with symmetrically distributed limiting rings 214 located on the upper and lower sides of the pull rope 205. The opening of the slide groove 201 is provided with a limiting block 206 located on the sliding path of the slider 203. A limiting block 215 is provided between the mounting seats 207. Use storage structure 200; When the cabinet doors need to be opened, cabinet doors 101 and 102 are opened relative to each other. The central block 209 at one end of the cabinet door drives the rotating shaft 208 to rotate around the mounting base 207. During the rotation of the rotating shaft 208, the torsion springs 210, which are sleeved on its outer side and fixed at both ends to the mounting base 207 and the central block 209 respectively, store their own energy and drive cabinet doors 101 and 102 to flip outward, generating a reverse elastic force, so that cabinet doors 101 and 102 automatically open. After being positioned by the limiting block 215, cabinet doors 101 and 102 correspond to the storage slots 202. At this time, the angle of the cabinet doors is completely aligned with the storage slots 202 on both sides of the cabinet body 100. Once the opening angle is set, the coil spring 212 unfolds using its own elastic force, causing the rotating shaft 208 to rotate. As the rotating shaft 208 rotates, the pull rope 205 is wound up, pulling the slider 203 to move, causing cabinet door 101 and cabinet door 202 to enter the storage slot 202. At this time, the cabinet door is completely slid into the storage slot 202, achieving hidden storage without occupying the operating space at the front of the cabinet 100. When the cabinet door needs to be closed, the sliding door is pulled out of the storage slot 202. Cabinet door 101 and cabinet door 202, detached from the storage slot 202, open and close the front of the cabinet 100 by rotating the rotating shaft 208.

[0021] After the cabinet door is opened, it slides completely into the storage slots 202 on both sides of the cabinet body 100 through the storage structure 200. No parts protrude outward to obstruct the front area of ​​the cabinet body 100. Compared with traditional outward-opening cabinet doors, it can expand the maintenance and operation space, making it easier for staff to inspect, adjust wiring and maintain the electrical components inside the ring main unit. The storage slots provide physical protection for the opened cabinet door, avoiding the problem of traditional outward-opening cabinet doors being easily damaged by handling equipment and personnel collisions, extending the service life of the cabinet door. At the same time, it can reduce the risk of staff being bumped by the cabinet door during maintenance, improving on-site operation safety. The torsion spring 210 provides elastic assistance when rotating, and the disc spring 212 provides reset power for the sliding slider 203. The two work together to reduce the operating force when opening and closing the cabinet door. Compared with traditional cabinet doors without elastic assistance, it can reduce the operating force. Positioning block one prevents the slider 203 from disengaging, limiting block two 215 limits the cabinet door angle, limiting ring 214 prevents the pull rope 205 from shifting, and positioning cylinder 302 prevents the spring 303 from shifting, ensuring that each component does not shift or disengage during operation, ensuring long-term reliability.

[0022] Traditional outward-opening cabinet doors need to be extended outwards after opening, obstructing the front maintenance area of ​​the cabinet 100 and resulting in limited operating space when maintaining internal components. The utility model hides the cabinet doors on both sides of the cabinet 100 through the storage structure 200, completely freeing up operating space and meeting the needs of large tools or multi-person collaborative maintenance. Traditional outward-opening cabinet doors have no protective structure and are easily damaged by external impacts in industrial sites. Furthermore, outward-opening parts are prone to bumping into workers. The utility model stores the cabinet doors inside the cabinet 100, avoiding direct external force and eliminating the risk of personnel bumping into them, thus balancing equipment protection and personnel safety. Traditional cabinet doors lack elastic assistance, requiring significant manual force to rotate and slide. Fixed structures 300 require tools to unlock. The utility model provides elastic assistance through torsion springs 210 and disc springs 212, reducing the operating force. The fixed structure 300 does not require tools to unlock, improving operational convenience. Example

[0023] Please see Figure 1-7 As shown, as well as; The fixed structure 300 includes a docking groove 301 opened inside the front end of cabinet door 101 and a docking box 308 embedded inside the front end of cabinet door 2 102. The upper end of the docking groove 301 has a slot 306 inside. The upper end of the docking box 308 has a positioning rod 304 that is inserted into the slot 306. The outer wall of the positioning rod 304 is sleeved with a support ring 305. The lower end of the support ring 305 is provided with a spring 303 that is connected to the lower inner wall of the docking box 308. The front end of the docking box 308 has a travel groove 309. A handle 307 connected to the support ring 305 is slidably installed inside the travel groove 309. The lower end of the docking box 308 has a positioning cylinder 302 located inside the spring 303 and slidably sleeved on the lower outer wall of the positioning rod 304. Use of fixed structure 300; When the cabinet door is reset and fits against the front end of the cabinet body 100, the spring 303 inside the docking box 308 is in a naturally extended state. The upper end of the spring 303 applies an upward push to the positioning rod 304 through the support ring 305. Under the action of the push, the positioning rod 304 slides upward along the inner wall of the docking box 308, and its upper end finally inserts into the slot 306 in the cabinet door docking groove 301. Through the insertion structure of the positioning rod 304 and the slot 306, the automatic fixation of the cabinet door structure is realized. At the same time, the positioning cylinder 302 at the lower end of the docking box 308 can limit the lateral displacement of the spring 303, prevent the positioning rod 304 from tilting when the spring 303 extends and retracts, ensure that the positioning rod 304 is accurately inserted into the slot 306, and improve the fixation reliability. When the cabinet door needs to be opened again, pull down the handle 307 at the front end of the docking box 308. The handle 307 slides along the travel groove 309 of the docking box 308. Since one end of the handle 307 is fixedly connected to the support ring 305, the support ring 305 moves down synchronously during the sliding process. The support ring 305 moves down to compress the spring 303, and at the same time, the positioning rod 304 slides down along the inner wall of the positioning cylinder 302. When the upper end of the positioning rod 304 is completely disengaged from the slot 306 of the cabinet door docking groove 301, the cabinet door is unlocked. At this time, the cabinet door can be opened according to the operation procedure of the storage structure 200. The entire unlocking process does not require tools and can be completed simply by pulling down the handle 307. The operation is convenient and efficient.
