Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and more specifically, to an outdoor AC distribution box with a protective structure. Background Technology

[0002] In existing technologies, with the widespread application of outdoor AC distribution boxes in power facilities, communication equipment, and traffic control, their working environments are often quite harsh, such as exposure to wind, sun, rain, dust, drastic temperature changes, and even mechanical impact. Therefore, the components inside the distribution box need reliable protection and secure fixing.

[0003] The components inside outdoor AC distribution boxes typically include important parts such as switches, circuit breakers, and relays. These components need to ensure their stability and safety during operation. However, the existing distribution box protection structure design is insufficient and cannot fully protect the components from the influence of the external environment. When the distribution box is subjected to severe external vibration or impact, the internal components may become loose, displaced, or even damaged, leading to abnormal circuit function.

[0004] Outdoor distribution boxes require regular inspection, maintenance, and replacement of their internal components during actual use. However, the installation and removal of protective covers in existing technologies usually require tools and are quite cumbersome. When the protective cover is fixed with bolts, operators need to use screwdrivers to remove the bolts one by one. The disassembly and assembly process is time-consuming and laborious, especially in outdoor high-altitude operations or in severe weather conditions, which greatly increases the difficulty of operation.

The connecting rod 7 can extend through the mounting plate 3 and engage with the connecting pipe 6 at the back end of the box body for quick connection. The quick-connect mechanism includes a slot 8, a horizontal pressure plate 9, a tension spring 10, a side pressure plate 11, a thrust spring 12, and a directional ring 13. The slot 8 is located on the side wall of the connecting rod 7. The horizontal pressure plate 9 is horizontally slidably mounted on the side wall of the connecting tube 6. The tension spring 10 is mounted between one end of the connecting tube 6 and the horizontal pressure plate 9. The side pressure plate 11 is rotatably mounted on the side wall of the connecting tube 6. The thrust spring 12 is mounted between the connecting tube 6 and the side pressure plate 11. The directional ring 13 is directionally slidably mounted on the outer wall of the connecting tube 6. The inner wall of the directional ring 13 presses the side pressure plate 11 downward, causing the horizontal pressure rod to press against the slot 8.

[0031] The snap-fit ​​auxiliary mechanism includes a fixed ring 14, a spring pin 15, a rotating ring 16, a ramp plate 17, and a push plate 18. The fixed ring 14 is fixedly installed on the outer wall of the snap-fit ​​tube 6. Multiple sets of spring pins 15 are installed on the fixed ring 14. The rotating ring 16 is limited to rotating on the outer wall of the snap-fit ​​tube 6. One end of the spring pin 15 can extend into one end face of the rotating ring 16 to cooperate and support the rotation. The ramp plate 17 is installed at the bottom end of the rotating ring 16. The push plate 18 is installed at the top end of the directional ring 13. The rotating ramp plate 17 causes the push plate 18 and the directional ring 13 to move in a directional manner.

[0032] A door 19 is rotatably mounted on the front end face of the box body 1, and a toolbox 20 is mounted on the inner wall of the door 19.

[0033] A control switch assembly 21 is installed on the protective cover 5, and the control switch assembly 21 is electrically connected to the component 2.

[0034] A base 22 is installed on the inner wall of the housing 1, and the other end of the base 22 is fixedly connected to the back end face of the mounting plate 3.

[0035] A connecting plate 23 is installed at the bottom of the side wall of the card tube 6, and the connecting plate 23 is fixedly installed on the back end face of the box 1.

[0036] A side plate 24 is installed on the side wall of the directional ring 13, and a return spring 25 is installed between the connecting plate 23 and the side plate 24.

[0037] Anti-collision pads 26 are installed around the box body 1, and fixing plates 27 are installed at both ends of the anti-collision pads 26, and the anti-collision pads 26 are fixed around the box body 1 by the fixing plates 27.

[0038] In this embodiment, when the protective installation mechanism is required to operate, component 2 is firmly fixed inside the distribution box by the mounting plate 3, ensuring the stability of the equipment during operation. The protective cover 5 is connected to the mounting plate 3 by the support plate 4 around its perimeter and is fixed by the snap-fit ​​rod 7 and the snap-fit ​​tube 6. The protective cover 5 effectively isolates the external environment from the influence of the component 2, ensuring the safe operation of the component 2. The protective cover 5 extends into the mounting plate 3 through the snap-fit ​​rod 7, and quick assembly and disassembly are achieved by using the snap-fit ​​rod 7 and the snap-fit ​​tube 6 on the back of the box 1. When the quick-connect mechanism is in operation, after the connecting rod 7 is inserted into the connecting tube 6, the slot 8 on its side wall will contact the horizontal pressure plate 9 in the connecting tube 6. In the initial state, the horizontal pressure plate 9 is elastically acted upon by the anti-tension spring 10 and moves away from the slot 8. The side pressure plate 11 rotates under the action of the anti-push spring 12, causing the side pressure plate 11 to move away from the horizontal pressure plate 9 and apply lateral pressure to the connecting rod 7, making it more firmly fixed in the connecting tube 6. The directional ring 13 slides along the outer wall of the connecting tube 6 and presses the side pressure plate 11 downward through its inner wall, making the horizontal pressure plate 9 press more tightly against the slot 8, thereby achieving a firm connection. When the locking auxiliary mechanism is required to operate, one end of the spring pin 15 is installed on the fixed ring 14, and the other end can extend into one end face of the rotating ring 16 to provide support for the rotating ring 16. The rotating ring 16 rotates around the locking tube 6 to limit its rotation, which drives the ramp plate 17 to rotate. When the rotating ring 16 rotates, the ramp plate 17 at its bottom contacts the push plate 18, generating a directional thrust. The push plate 18 is pushed by the ramp plate 17, which drives the directional ring 13 to slide along the outer wall of the locking tube 6. The directional ring 13 further presses the side pressure plate 11, making the horizontal pressure plate 9 press more tightly against the locking groove 8, thereby enhancing the locking firmness.

[0039] More specifically, the housing 1 is fixed in the required location, and the internal components 2 are fixed by the cooperation of the base 22 and the mounting plate 3. The protective cover 5 is quickly installed inside the housing 1 by the cooperation of the support plate 4, the snap-fit ​​rod 7 and the snap-fit ​​tube 6. After the snap-fit ​​rod 7 is inserted into the snap-fit ​​tube 6, the quick snap-fit ​​mechanism completes the quick fixation. Rotating the rotating ring 16 of the snap-fit ​​auxiliary mechanism, the ramp plate 17 pushes the push plate 18 to move, which drives the directional ring 13 to slide, further pressing the snap-fit ​​rod 7 to ensure firmness. The front door 19 of the housing 1 can rotate flexibly, making it easy for operators to open the door 19 to inspect, maintain or replace the internal components 2. The toolbox 20 inside the door 19 provides convenience for operation. The control switch assembly 21 on the protective cover 5 is electrically connected to the internal components 2 to control the external power output. The anti-collision pads 26 are installed around the housing 1 to prevent damage to the housing 1 due to collisions during transportation or installation. The design of the protective cover 5 isolates the influence of external dust and ensures the long-term stable operation of the internal components 2.

[0040] In summary, during the use or operation of the overall equipment: when the protective installation mechanism is required, component 2 is firmly fixed inside the distribution box by the mounting plate 3, ensuring the stability of the equipment during operation. The protective cover 5 is connected to the mounting plate 3 by the support plate 4 on all four sides, and is fixed by the clamping rod 7 and the clamping pipe 6. The protective cover 5 effectively isolates the influence of the external environment on component 2, ensuring the safe operation of component 2. The protective cover 5 extends into the mounting plate 3 by the clamping rod 7, and quick assembly and disassembly are achieved by using the clamping rod 7 and the clamping pipe 6 on the back of the box 1. When the quick-connect mechanism is in operation, after the connecting rod 7 is inserted into the connecting tube 6, the slot 8 on its side wall will contact the horizontal pressure plate 9 in the connecting tube 6. In the initial state, the horizontal pressure plate 9 is elastically acted upon by the anti-tension spring 10 and moves away from the slot 8. The side pressure plate 11 rotates under the action of the anti-push spring 12, causing the side pressure plate 11 to move away from the horizontal pressure plate 9 and apply lateral pressure to the connecting rod 7, making it more firmly fixed in the connecting tube 6. The directional ring 13 slides along the outer wall of the connecting tube 6 and presses the side pressure plate 11 downward through its inner wall, making the horizontal pressure plate 9 press more tightly against the slot 8, thereby achieving a firm connection. When the locking auxiliary mechanism is required to operate, one end of the spring pin 15 is installed on the fixed ring 14, and the other end can extend into one end face of the rotating ring 16 to provide support for the rotating ring 16. The rotating ring 16 rotates around the locking tube 6 to limit its rotation, which drives the ramp plate 17 to rotate. When the rotating ring 16 rotates, the ramp plate 17 at its bottom contacts the push plate 18, generating a directional thrust. The push plate 18 is pushed by the ramp plate 17, which drives the directional ring 13 to slide along the outer wall of the locking tube 6. The directional ring 13 further presses the side pressure plate 11, making the horizontal pressure plate 9 press more tightly against the locking groove 8, thereby enhancing the locking firmness.

[0041] The housing 1 is fixed in the required location. The internal components 2 are fixed by the cooperation of the base 22 and the mounting plate 3. The protective cover 5 is quickly installed inside the housing 1 by the cooperation of the support plate 4, the snap-fit ​​rod 7 and the snap-fit ​​tube 6. After the snap-fit ​​rod 7 is inserted into the snap-fit ​​tube 6, the quick snap-fit ​​mechanism completes the quick fixation. Rotating the rotating ring 16 of the snap-fit ​​auxiliary mechanism pushes the push plate 18 to move by the ramp plate 17, which drives the directional ring 13 to slide, further pressing the snap-fit ​​rod 7 to ensure firmness. The front door 19 of the housing 1 can rotate flexibly, which makes it easy for the operator to open the door 19 to inspect, maintain or replace the internal components 2. The toolbox 20 inside the door 19 provides convenience for operation. The control switch assembly 21 on the protective cover 5 is electrically connected to the internal components 2 to control the external power output. The anti-collision pads 26 are installed around the housing 1 to prevent the housing 1 from being damaged by collisions during transportation or installation. The design of the protective cover 5 isolates the influence of external dust and ensures the long-term stable operation of the internal components 2.
