Description

Technical Field

[0001] This utility model relates to the field of communication equipment cabinet technology, and more specifically, it relates to a communication equipment cabinet. Background Technology

[0002] In the application scenario of communication equipment cabinets, a lot of heat is generated during the operation of the equipment, which needs to be dissipated in time through the heat dissipation system to ensure the normal operation of the equipment. Especially under high load or high temperature environment, the heat dissipation effect directly affects the performance and service life of the equipment. At the same time, since the equipment is running continuously, the heat dissipation components need to be cleaned and maintained regularly to maintain good heat dissipation effect.

[0003] However, the communication equipment cabinets currently on the market have obvious shortcomings. Traditional heat dissipation components are usually installed by bolt fixing or clip connection, which is cumbersome to install and disassemble, requires tools and is time-consuming. At the same time, since the cooling fans and filter plates work in a dusty environment for a long time, they need to be cleaned frequently, but the existing fixed structure makes disassembly and cleaning difficult. This not only increases the workload of maintenance personnel, but also prolongs the equipment maintenance time, and cannot meet the requirements of modern communication equipment for rapid maintenance and efficient heat dissipation.

The fixing mechanism includes insert rods 5, fixing sleeves 6, snap-fit ​​pieces 7, slots 8, sliding grooves 9, connecting frames 10, sliding sleeves 11, unlocking sleeves 12, and a limiting mechanism. Multiple sets of insert rods 5 are installed on the outer wall of the cabinet body 1. The fixing sleeves 6 are located on the top surface of the mounting frames 2. Multiple sets of snap-fit ​​pieces 7 are distributed on the inner wall of the fixing sleeves 6. Multiple sets of slots 8 are distributed on the outer wall of the insert rods 5.

The sliding sleeves 11 are fixed to the outer side of the connecting frame 10. The unlocking sleeve 12 slides on the inner wall of the fixing sleeves 6 and is connected to the connecting frame 10.

[0030] The limiting mechanism includes a connecting sleeve 13, a sliding rod 14, a limiting block 15, a rotating sleeve 16, a limiting groove 17, and a clearance groove 18. The connecting sleeve 13 is fixed to the bottom surface of the sliding sleeve 11. Multiple sets of sliding rods 14 are distributed on the bottom surface of the connecting sleeve 13. The limiting block 15 is installed at the bottom end of the multiple sets of sliding rods 14. The rotating sleeve 16 is rotatably installed on the outer wall of the fixed sleeve 6. Multiple sets of limiting grooves 17 are distributed on the top surface of the rotating sleeve 16 and are slidably connected to the multiple sets of limiting blocks 15 respectively. The clearance groove 18 is provided at one end of the multiple sets of limiting grooves 17.

[0031] A push spring 19 is connected to the bottom surface of the connecting sleeve 13. Multiple sets of push springs 19 are provided, and each set of push springs 19 is connected to a mounting plate 20 at its bottom end. Multiple sets of mounting plates 20 abut against the top surface of the rotating sleeve 16. When the push spring 19 is compressed, it provides downward pressure to the mounting plate 20 to ensure that the mounting plate 20 and the rotating sleeve 16 maintain stable contact.

[0032] The top surface of the rotating sleeve 16 is provided with an annular groove 21, and the bottom surfaces of multiple sets of mounting plates 20 are all equipped with arc-shaped sliders 22. The multiple sets of arc-shaped sliders 22 slide in the annular groove 21, and the arc-shaped sliders 22 form a circular motion trajectory in the annular groove 21, guiding the rotating sleeve 16 to achieve smooth rotation.

[0033] A compression spring 23 is installed on the top surface of the inner sleeve 6. Multiple sets of compression springs 23 are provided, and each of them is connected to a pressure plate 24 at its bottom end.

[0034] The outer wall of the insertion rod 5 is provided with a positioning groove 25, and the inner wall of the fixing sleeve 6 is provided with a positioning block 26. Multiple sets of positioning grooves 25 and positioning blocks 26 are provided and are slidably connected. The positioning block 26 is embedded in the positioning groove 25 to form a limiting fit, preventing the insertion rod 5 from rotating inside the fixing sleeve 6.

[0035] The bottom end of the unlocking sleeve 12 is connected to a guide sleeve 27, and the fixed sleeve 6 is provided with a guide rod 28. There are multiple sets of guide rods 28, all of which are slidably connected to the guide sleeve 27. The guide rod 28 provides a linear motion track for the guide sleeve 27 to ensure the movement direction of the unlocking sleeve 12.

[0036] The diameters of multiple relief grooves 18 are all larger than those of the limiting block 15. The size difference ensures that the limiting block 15 can fully enter the interior of the relief groove 18, thereby realizing the function of releasing the limit.

[0037] In this embodiment, when the filter plate 29 and the cooling fan 3 need to be installed, the insertion rod 5 is inserted into the mounting frame 2 and the filter plate 29, and then into the fixing sleeve 6. Multiple sets of positioning blocks 26 are positioned and inserted into the positioning groove 25. The top of the insertion rod 5 pushes multiple sets of pressure plates 24 and squeezes the pressure spring 23. Multiple sets of snap-fit ​​plates are engaged in the slot 8 to snap the insertion rod 5. Multiple sets of snap-fit ​​pieces 7 are set as elastic pieces with a certain degree of extension. The snap-fit ​​pieces 7 are engaged in the slot 8 by the push of multiple sets of pressure springs 23. Multiple sets of limiting blocks 15 slide in the limiting groove 17 and squeeze multiple sets of push springs 19 to limit the sliding sleeve 11 and the unlocking sleeve 12.

[0038] More specifically, when disassembly is required, the rotating sleeve 16 is rotated, and multiple sets of arc-shaped sliders 22 slide along the annular groove 21. When multiple sets of limiting blocks 15 slide into the relief groove 18, the limiting blocks 15 are released from contact with the outer wall of the rotating sleeve 16. Multiple sets of push springs 19 push the connecting sleeve 13 and the sliding sleeve 11, causing the connecting frame 10 to slide along the sliding groove 9 and pull the unlocking sleeve 12 to push multiple sets of snap-fit ​​pieces 7, causing the multiple sets of snap-fit ​​pieces 7 to move outward and disengage from the snap-fit ​​groove 8, releasing the snap-fit ​​with the insertion rod 5. Multiple sets of compression springs 23 reset and push the insertion rod 5 to disengage from the fixing sleeve 6. Then the mounting frame 2 and the filter plate 29 can be disassembled.

[0039] In summary, during the use or operation of the overall equipment: when it is necessary to install the filter plate 29 and the cooling fan 3, the insertion rod 5 is inserted into the mounting frame 2 and the filter plate 29, and then into the fixing sleeve 6. Multiple sets of positioning blocks 26 are used to position and insert into the positioning groove 25. The top of the insertion rod 5 pushes multiple sets of pressure plates 24 and squeezes the pressure spring 23. Multiple sets of snap-fit ​​plates are engaged in the slot 8 to snap the insertion rod 5. Multiple sets of snap-fit ​​pieces 7 are set as elastic pieces with a certain degree of extension. The snap-fit ​​pieces 7 are engaged in the slot 8 by the push of multiple sets of pressure springs 23. Multiple sets of limiting blocks 15 slide in the limiting groove 17 and squeeze multiple sets of push springs 19 to limit the sliding sleeve 11 and the unlocking sleeve 12.

[0040] When disassembly is required, rotate the rotating sleeve 16, and at the same time, multiple sets of arc-shaped sliders 22 slide along the annular groove 21. When multiple sets of limiting blocks 15 slide into the relief groove 18, the limiting blocks 15 release their contact with the outer wall of the rotating sleeve 16. Multiple sets of push springs 19 push the connecting sleeve 13 and the sliding sleeve 11, causing the connecting frame 10 to slide along the sliding groove 9 and pull the unlocking sleeve 12 to push multiple sets of snap-fit ​​pieces 7, causing the multiple sets of snap-fit ​​pieces 7 to move outward and disengage from the snap-fit ​​groove 8, releasing the snap-fit ​​with the insertion rod 5. Multiple sets of compression springs 23 reset and push the insertion rod 5 to disengage from the fixing sleeve 6. Then the mounting frame 2 and the filter plate 29 can be disassembled.
