Description

Technical Field

[0001] This utility model relates to the field of metal cable tray technology, specifically a metal cable tray with a protective structure. Background Technology

[0002] In power transmission, communication cabling, and industrial automation systems, metal cable trays serve as the core carrier for cable laying, playing a crucial role in "supporting, protecting, and organizing cables," and are widely used in buildings, factories, rail transit, and other scenarios.

[0003] According to announcement number CN218386561U, a dustproof high-strength trough-type cable tray includes a cable tray with connecting blocks fixedly connected to the bottom of both the left and right sides of the cable tray. Protective covers are movably connected to the surfaces of the connecting blocks via pins. This invention, by placing the cables inside the cable tray and then rotating the two protective covers, allows them to shield the top of the cable tray when the covers rotate about the pins inside the connecting blocks to the top of the cable tray and the two covers come into contact with each other.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this equipment uses a heat sink to dissipate heat from the cables. The heat sink's metallic thermal conductivity and air convection create a dual heat dissipation mode to reduce the cable's operating temperature. However, after long-term operation, external dust easily accumulates on the surface of the heat sink and in the joints with the lower cable tray. Since the heat sink is often fixed in place, if the cable tray's disassembly and assembly structure is not optimized, cleaning requires disassembling multiple sets of fixed components, making the operation cumbersome and extending the time required for each cleaning cycle. Utility Model Content

[0006] The purpose of this invention is to provide a metal cable tray with a protective structure to solve the problems mentioned in the background art.

[0012] Preferably, the number of connecting seats is four, and they are arranged in pairs, with two connecting seats located on the outside of the four rectangular slots.

[0013] Preferably, the limiting component includes a plug rod, which is fixedly connected to the center of the connecting seat on the side away from the rectangular groove. A sliding plate is fixedly connected to the periphery of the plug rod surface. A limiting groove is formed inside the rotating plate on the side away from the connecting seat. A limiting block is inserted into the limiting groove. A mounting plate is fixedly connected to the limiting block on the side away from the connecting seat. A frustum is fixedly connected between the upper and lower mounting plates. A circular hole groove is formed inside the frustum.

[0014] Preferably, the fixing mechanism includes a long groove, which is opened on the front and rear sides of the lower bridge frame. A long block is inserted into the long groove. Long plates are fixedly connected to the outer sides of the two long blocks. Locking plates are hinged to the left and right sides of the long plates respectively. A locking block is fixedly connected to the locking plate on the side near the lower bridge frame. The top plate has slots on the left and right sides. The surface of the locking block engages with the inside of the slot. The limiting block disengages from the limiting slot. At the same time, the sliding plate on the surface of the insert rod slides along the slide groove of the frustum to ensure smooth movement.

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Combination Figures 1 to 5 A metal cable tray with a protective structure includes a lower cable tray 1, a top plate 2 and a heat dissipation plate 3. The lower cable tray 1 and the top plate 2 are provided with a fixing mechanism 4, and the lower cable tray 1 and the heat dissipation plate 3 are provided with a disassembly and assembly mechanism 5.

[0033] The disassembly and assembly mechanism 5 includes a plug-in component 51 and a limiting component 52, with the limiting component 52 disposed on the plug-in component 51;

[0034] The plug-in assembly 51 includes a square slot 511, which is opened inside the lower bridge frame 1. There are two square slots 511, and the front and rear sides of the two square slots 511 are set as openings. Rectangular slots 512 are opened around the front and rear sides of the lower bridge frame 1. Rectangular blocks 513 are fixedly connected to the left and right sides of the heat sink 3. The surface of the rectangular blocks 513 is inserted into the inside of the rectangular slots 512. A fixing rod 516 is fixedly connected to the side of the rectangular blocks 513 away from the lower bridge frame 1. A rotating plate 515 is rotatably connected to the surface of the fixing rod 516. Connecting seats 517 are fixedly connected to the front and rear sides of the lower bridge frame 1. Square slots 514 are opened at the top and bottom of the connecting seats 517.

[0035] The rectangular slots 512 are grouped into four, with openings on the outer sides of the front and rear rectangular slots 512. The four rectangular slots 512 and the square slot 511 are connected through the openings. The outer sides of the upper and lower square slots 514 and the left and right sides are also open. The surface of the rotating plate 515 is inserted into the inside of the square slot 514. There are four connecting seats 517 in pairs, with two connecting seats 517 located on the outer sides of the four rectangular slots 512.

[0036] The limiting component 52 includes a plug rod 524, which is fixedly connected to the center of the connecting seat 517 on the side away from the rectangular groove 512. A sliding plate 523 is fixedly connected to the periphery of the surface of the plug rod 524. A limiting groove 521 is formed inside the rotating plate 515 on the side away from the connecting seat 517. A limiting block 522 is inserted into the limiting groove 521. A mounting plate 526 is fixedly connected to the side of the limiting block 522 away from the connecting seat 517. A frustum 529 is fixedly connected between the upper and lower mounting plates 526. A circular hole groove 528 is formed inside the frustum 529. A sliding groove 527 is formed around the periphery of the inner wall of the circular hole groove 528. The surface of the plug rod 524 and the interior of the circular hole groove 528 pass through each other. The surface of the sliding plate 523 and the interior of the sliding groove 527 are slidably connected. Screws 525 are threadedly connected to the mounting plate 526 and the connecting seat 517.

[0037] Furthermore, pulling the frustum 529 causes the mounting plate 526 and the limiting block 522 to move synchronously, allowing the limiting block 522 to disengage from the limiting groove 521. At the same time, the sliding plate 523 on the surface of the insert rod 524 slides along the sliding groove 527 of the frustum 529 to ensure smooth movement. Next, rotate the rotating plate 515 around the fixed rod 516 so that it rotates out of the square groove 514 of the connecting seat 517, releasing the limitation on the rectangular block 513. Finally, pull the heat sink 3 upward so that the rectangular block 513 can be pulled out of the rectangular groove 512, and the heat sink 3 can be removed for cleaning of dust and debris.

[0038] Example 2

[0039] See Figure 1-7Furthermore, based on Embodiment 1, the fixing mechanism 4 includes a long groove 42, which is opened on the front and rear sides of the lower bridge frame 1. A long block 43 is inserted into the long groove 42. A long plate 41 is fixedly connected to the outer side of the two long blocks 43. A locking plate 46 is hinged to the left and right sides of the long plate 41 respectively. A locking block 45 is fixedly connected to the side of the locking plate 46 near the lower bridge frame 1. A slot 44 is opened on the left and right sides of the top plate 2. The surface of the locking block 45 is engaged with the inside of the slot 44. A through groove is opened on the front and rear sides of the top plate 2. The surface of the long block 43 is inserted through the through groove opened on the front and rear sides of the top plate 2.

[0040] Furthermore, pulling the frustum 529 causes the mounting plate 526 and the limiting block 522 to move synchronously, allowing the limiting block 522 to disengage from the limiting groove 521. At the same time, the sliding plate 523 on the surface of the insert rod 524 slides along the sliding groove 527 of the frustum 529 to ensure smooth movement. Next, rotate the rotating plate 515 around the fixed rod 516 so that it rotates out of the square groove 514 of the connecting seat 517, releasing the limitation on the rectangular block 513. Finally, pull the heat sink 3 upward so that the rectangular block 513 can be pulled out of the rectangular groove 512, and the heat sink 3 can be removed for cleaning of dust and debris.

[0041] In actual operation, when this device is used, the cable is laid in the two square slots 511 inside the lower cable tray 1. The square slots 511 have openings on both the front and rear sides, forming air circulation channels and providing basic heat dissipation space for the cable. Simultaneously, the heat dissipation plate 3, through rectangular blocks 513 on the left and right sides, interlocks with the rectangular slots 512 on the front and rear sides of the lower cable tray 1, tightly covering the corresponding square slot positions on the bottom or sides of the lower cable tray 1. The heat generated by the cable during operation is conducted to the heat dissipation plate 3 through the housing of the lower cable tray 1. The heat dissipation plate 3 utilizes the thermal conductivity of metal to quickly dissipate the heat to the outside; combined with the air circulation effect of the square slots 511, this effectively reduces the cable's operating temperature, preventing high temperatures from affecting cable performance or causing safety hazards.

[0042] Unscrew the screws 525 between the mounting plate 526 and the connecting seat 517 to release their fixation. Then pull the frustum 529 away from the connecting seat 517, causing the mounting plate 526 and the limiting block 522 to move synchronously, so that the limiting block 522 can be dislodged from the limiting groove 521. At the same time, the sliding plate 523 on the surface of the insert rod 524 slides along the sliding groove 527 of the frustum 529 to ensure smooth movement. Next, rotate the rotating plate 515 around the fixing rod 516 so that it can rotate out of the square groove 514 of the connecting seat 517, releasing the limitation on the rectangular block 513. Finally, pull the heat sink 3 upward to pull the rectangular block 513 out of the rectangular groove 512, and then remove the heat sink 3 for cleaning of dust and debris.

[0043] After cleaning, align the rectangular block 513 of the heat sink 3 with the rectangular groove 512 and insert it. Rotate the rotating plate 515 so that it is engaged in the square groove 514 of the connecting seat 517. Push the frustum 529 so that the limiting block 522 is inserted into the limiting groove 521 of the rotating plate 515 and the slide plate 523 slides back to the original position of the slide groove 527. Finally, screw in the screws 525 to fix the mounting plate 526 and the connecting seat 517, and complete the stable installation of the heat sink 3.

[0044] The top plate 2 covers the top of the lower cable tray 1, aligning the through slots on the front and rear sides of the top plate 2 with the long slots 42 of the lower cable tray 1. The long block 43 is inserted into the long slot 42 to initially define the position of the top plate 2. Then, the locking plate 46 is rotated around the hinge of the long plate 41 to make the locking block 45 engage with the locking slots 44 on the left and right sides of the top plate 2, preventing the top plate 2 from shifting or falling off during use. At the same time, the top plate 2 can protect the cables in the lower cable tray 1, preventing external dust, debris from falling in or external impacts from damaging the cables.
