[0017] 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.
[0018] like Figures 1 to 4 As shown, this utility model provides a dustproof and waterproof ring main unit, including a cabinet body 1. The inner walls on both sides of the cabinet body 1 are provided with an adjustment mechanism 2. Both sides of the cabinet body 1 are provided with an isolation mechanism 3. The adjustment mechanism 2 includes multiple adjustment frames 20. One side of each pair of adjustment frames 20 is fixedly connected to the inner walls on both sides of the cabinet body 1. One side of each pair of adjustment frames 20 is provided with a sliding adjustment plate 25. One side of the multiple adjustment plates 25 is provided with a fixed equipment mounting frame 23. One side of the adjustment frame 20 is provided with multiple adjustment ports 21 that are evenly distributed. Two symmetrically distributed locking pins 27 are inserted into one side of the adjustment plate 25. The locking pins 27 are engaged with the adjustment ports 21. When it is necessary to adjust the height of the equipment mounting frame 23 to adapt to the installation requirements of different equipment, the operator first holds the handle 26 on the locking pin 27 and pulls the locking pin 27 outward, so that the locking groove 28 on the outside of the locking pin 27 is separated from the adjustment port 21 on the adjustment frame 20. At this time, the sliders 24 at both ends of the adjusting plate 25 can slide freely in the slide groove 22 of the adjusting frame 20. According to the equipment installation requirements, the operator slides the adjusting plate 25 to a suitable height, and then inserts the locking pin 27 into the corresponding adjusting port 21 so that the locking groove 28 and the adjusting port 21 are re-engaged, thereby fixing the position of the adjusting plate 25 and the equipment mounting frame 23 and completing the adjustment of the height of the equipment mounting frame 23.
[0019] Specifically, the isolation mechanism 3 includes a concave plate 30, one side of which is fixedly connected to the inner wall of one side of the cabinet 1. An operating opening 37 is provided on one side of the concave plate 30. An isolation plate 31 is slidably mounted on the inner side of the concave plate 30. A handle 36 is fixedly mounted on one side of the isolation plate 31, and a limiting strip 34 is fixedly mounted on one side of the isolation plate 31. Two horizontally distributed limiting grooves 33 are provided on the inner wall of one side of the cabinet 1. The limiting grooves 33 engage with the limiting strips 34. When it is necessary to operate or maintain the equipment inside the cabinet, the operator holds the handle 36 on the isolation plate 31 and pulls the isolation plate 31 upwards, causing it to slide upwards through the isolation opening 32 on the upper surface of the concave plate 30. During the sliding process, the limiting strip 34 on one side of the isolation plate 31 slides within the limiting groove 33 on the inner wall of one side of the cabinet 1. Simultaneously, the limiting plates 35 on both sides of the inner wall of the concave plate 30 slide against the isolation plate 31, providing guidance and limiting functions to prevent the isolation plate 31 from shifting. When the partition plate 31 is slid to the appropriate position and the operating port 37 is fully exposed, the equipment inside the cabinet can be operated and maintained. After the operation is completed, the partition plate 31 is pushed down to its original position to close the operating port 37, thus providing waterproof and dustproof isolation and protection.
[0020] Furthermore, the handle 26 is fixedly mounted on one side of the locking pin 27, providing an easy gripping point for the operator. When it is necessary to adjust the height of the equipment mounting bracket 23, the operator can more easily and stably pull out and insert the locking pin 27 by holding the handle 26, avoiding the slippage that may occur when operating the locking pin 27 directly by hand, thus improving the convenience and accuracy of operation.
[0021] Furthermore, the engaging groove 28 on the outer side of the engaging pin 27 engages with the adjustment port 21, enhancing the connection stability between the engaging pin 27 and the adjustment port 21. Compared to simple planar contact, the engaging groove 28 can better embed itself into the adjustment port 21, preventing the engaging pin 27 from loosening or falling off due to equipment vibration or external forces during use. This ensures that the equipment mounting bracket 23 can be firmly fixed in the required position after height adjustment, guaranteeing the stability of equipment operation.
[0022] It is worth noting that the multiple annularly distributed anti-slip grooves 29 on the outer side of the grip 26 increase the friction between the operator's hand and the grip 26. When the grip 26 is pulled out or inserted into the locking pin 27, the anti-slip grooves 29 can effectively prevent the hand from slipping, especially when the hands are wet or oily, ensuring that the operator can still maintain a stable grip on the grip 26, further improving the safety and reliability of the operation.
[0023] It is worth noting that the sliders 24 fixed at both ends of the adjusting plate 25 slide in contact with the grooves 22 on one side of the adjusting frame 20. This structural design provides precise guidance for the sliding of the adjusting plate 25 on the adjusting frame 20. The sliders 24 slide within the grooves 22, ensuring that the adjusting plate 25 moves along a predetermined trajectory. This prevents the adjusting plate 25 from shifting or wobbling during sliding, making the height adjustment of the equipment mounting frame 23 more stable and accurate. It also reduces wear on the adjusting frame 20 caused by the unstable movement of the adjusting plate 25.
[0024] It is worth mentioning that the limiting plates 35 fixed to the inner walls on both sides of the concave plate 30 slide against the isolation plate 31, which plays a limiting and guiding role in the sliding of the isolation plate 31. During the up-and-down sliding process of the isolation plate 31, the limiting plates 35 can prevent the isolation plate 31 from shifting to the sides, ensuring that the isolation plate 31 always slides in the vertical direction, so that the operating port 37 can be accurately exposed and closed, improving the operating accuracy and reliability of the isolation mechanism 3, and also enhancing the stability of the isolation plate 31 during the sliding process.
[0025] It is worth emphasizing that the isolation opening 32 on the upper surface of the concave plate 30 slides and fits snugly against the isolation plate 31, providing a suitable channel for the vertical sliding of the isolation plate 31. The size and shape of the isolation opening 32 match the isolation plate 31, ensuring that the isolation plate 31 can slide smoothly through the opening while effectively preventing external dust, moisture, etc., from entering the cabinet through the opening. During the sliding process of the isolation plate 31, the tight fit between the isolation opening 32 and the isolation plate 31 reduces gaps, further improving the waterproof and dustproof performance of the ring main unit.
[0026] Working principle: When the height of the equipment mounting bracket 23 needs to be adjusted to accommodate the installation requirements of different equipment, the operator first grasps the lever 26 on the locking pin 27 and pulls the locking pin 27 outward, causing the locking groove 28 on the outside of the locking pin 27 to separate from the adjustment port 21 on the adjustment bracket 20. At this time, the sliders 24 at both ends of the adjustment plate 25 can slide freely within the sliding grooves 22 of the adjustment bracket 20. According to the equipment installation requirements, the operator slides the adjustment plate 25 to a suitable height, and then inserts the locking pin 27 into the corresponding adjustment port 21, causing the locking groove 28 to re-engage with the adjustment port 21, thereby fixing the position of the adjustment plate 25 and the equipment mounting bracket 23, and completing the height adjustment of the equipment mounting bracket 23.
[0027] When it is necessary to operate or maintain the equipment inside the cabinet, the operator holds the handle 36 on the partition plate 31 and pulls the partition plate 31 upward, causing it to slide upward through the isolation opening 32 on the upper surface of the recessed plate 30. During the sliding process, the limiting strip 34 on one side of the partition plate 31 slides within the limiting groove 33 on the inner wall of one side of the cabinet body 1, while the limiting plates 35 on both sides of the inner wall of the recessed plate 30 slide and fit against the partition plate 31, serving as a guide and limiting element to prevent the partition plate 31 from shifting. When the partition plate 31 slides to the appropriate position and the operating opening 37 is fully exposed, the equipment inside the cabinet can be operated and maintained. After the operation is completed, the partition plate 31 is pushed downward to its original position, closing the operating opening 37 and providing waterproof and dustproof isolation protection.
