Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a fireproof and pressure-resistant cable tray. Background Technology

[0002] Cable trays are structured devices used to support, protect, and manage cables. Their main function is to collect and fix scattered cables in an orderly manner, preventing them from becoming messy, damaged by external forces, or corroded by the environment. They also facilitate later maintenance and expansion. They are widely used in electrical wiring systems in fields such as construction, industry, transportation, and energy, and serve as the "skeleton" for cable laying.

[0003] Cable trays can be classified into trough-type cable trays, tray-type cable trays, and ladder-type cable trays according to their structure. Trough-type cable trays are fully enclosed trough structures with the strongest protection, suitable for laying sensitive cables, and can isolate dust, water vapor and electromagnetic interference. They are often used in clean rooms, data centers, etc., but existing cable trays have certain inconveniences in use.

[0004] Existing cable trays are mainly fixed and installed using supports and hangers. However, they have two prominent problems in practical applications. First, because cable trays are often installed in complex environments (such as industrial workshops, subway tunnels, and building mezzanines), their tops are frequently subjected to external impacts, including accidental scrapes from production machinery, trampling by personnel, and impacts from falling objects. These external forces can create instantaneous impact or continuous pressure, which can easily lead to deformation of the top structure of the cable tray, cracking of the edges and corners, and even loosening of the overall connection. In severe cases, it may squeeze the internal cables, causing insulation damage or short circuits. Second, existing cable trays generally have poor fire resistance, making them prone to significant losses in the event of a fire.

[0005] Therefore, we propose a fire-resistant and pressure-resistant cable tray. Utility Model Content

[0006] In response to the problems in existing technologies, cable trays are often installed in complex environments where their tops are frequently subjected to external impacts, including accidental scrapes from production machinery, trampling by personnel, and impacts from falling objects. These external forces can create instantaneous impact or continuous pressure, easily leading to deformation of the top structure of the cable tray, cracking of edges and corners, and even loosening of the overall connection. In severe cases, they may squeeze the internal cables, causing insulation damage or short circuits. On the other hand, existing cable trays generally have poor fire resistance, which can easily cause significant losses in the event of a fire. This utility model provides a fire-resistant and pressure-resistant cable tray.

[0007] The technical solution adopted by this utility model is: a fireproof and pressure-resistant cable tray, including a frame box, a frame cover, a pressure-resistant component, and a positioning component. The pressure-resistant component includes an upper fixing block, a lower fixing block, a plug rod, a magnetic absorbing plate, a thread, a retaining ring, a lower through hole, a pressure-resistant spring, a connecting plate, and an upper through hole. The lower fixing block is located below the upper fixing block. The plug rod is disposed on the lower outer surface of the upper fixing block. The magnetic absorbing plate, the thread, and the retaining ring are all disposed on the outer wall of the plug rod. The magnetic absorbing plate is located above the retaining ring, and the retaining ring is located outside the thread. The lower through hole is disposed in the middle of the lower fixing block. The pressure-resistant spring is disposed on the upper outer surface of the lower fixing block. The connecting plate is disposed on the upper outer surface of the pressure-resistant spring, and the upper through hole is disposed in the middle of the connecting plate.

[0008] Furthermore, the positioning component includes a base, a partition plate, a first clamping plate, a second clamping plate, a limiting spring, and an upper baffle. The partition plate, the first clamping plate, and the second clamping plate are all disposed in the middle of the base. The limiting spring is disposed on the outer rear end surface of the first clamping plate and the second clamping plate. The upper baffle is fixedly installed on the outer front end surface of the second clamping plate.

[0009] Furthermore, a fireproof inner layer is fixedly installed on the inner wall of the shelf box, a rubber pad is provided in the middle of the shelf cover, and a soft rubber column is provided between the rubber pad and the shelf cover.

[0010] Furthermore, the upper fixing block is welded to the insertion rod, and the retaining ring is connected to the insertion rod via the thread.

[0011] Furthermore, the lower fixing block and the lower through hole are integrally formed, and the docking plate and the upper through hole are integrally formed.

[0012] Furthermore, the base and the partition plate are integrally formed, and the first clamping plate and the second clamping plate are movably connected to the partition plate and the base through the limiting spring.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, the anti-pressure component allows the insertion rod to pass through the upper and lower through holes to the bottom of the lower fixing block. During the penetration, the mating plate and the magnetic suction plate are magnetically attracted. Then, the retaining ring is installed on the insertion rod through the thread and pressed against the bottom end of the lower fixing block. When the cover is under pressure, the cover will drive the insertion rod to move downward, causing the insertion rod to compress the anti-pressure spring through the magnetic suction plate and the mating plate. The anti-pressure spring buffers the pressure, thereby improving the anti-pressure resistance of the cover and preventing the cover from deforming and squeezing the internal cables under pressure, thus avoiding damage to the insulation layer or short circuit.

[0015] 2. In this utility model, the positioning component can limit the first clamping plate and the second clamping plate by the limiting spring during use, so that the first clamping plate and the second clamping plate can clamp and fix the cable, which can facilitate the sorting and separation of the cable, avoid the cable from getting tangled, and facilitate subsequent maintenance.

[0022] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described below.

[0023] To address the problems existing in the background technology, this application proposes the following technical solution: a fire-resistant and pressure-resistant cable tray.

[0024] The specific technical solution includes a frame box 1, a frame cover 2, a pressure-resistant component 3, and a positioning component 4. The pressure-resistant component 3 includes an upper fixing block 301, a lower fixing block 302, an insert rod 303, a magnetic absorbing plate 304, a thread 305, a retaining ring 306, a lower through hole 307, a pressure-resistant spring 308, a connecting plate 309, and an upper through hole 310. The lower fixing block 302 is located below the upper fixing block 301. The insert rod 303 is disposed on the lower outer surface of the upper fixing block 301. The magnetic absorbing plate 304, the thread 305, and the retaining ring 306 are all... The magnetic suction plate 304 is located above the retaining ring 306 on the outer wall of the insertion rod 303. The retaining ring 306 is located outside the thread 305. The lower through hole 307 is located in the middle of the lower fixing block 302. The anti-compression spring 308 is located on the upper outer surface of the lower fixing block 302. The mating plate 309 is located on the upper outer surface of the anti-compression spring 308. The upper through hole 310 is located in the middle of the mating plate 309. The positioning component 4 includes a base 401, a partition plate 402, a first clamping plate 403, a second clamping plate 404, and a limiter. Spring 405, upper baffle 406, partition plate 402, first clamping plate 403, and second clamping plate 404 are all disposed in the middle of base 401. Limiting spring 405 is disposed on the outer rear end of first clamping plate 403 and second clamping plate 404. Upper baffle 406 is fixedly installed on the outer front end of second clamping plate 404. When in use, the anti-compression component 3 allows the insertion rod 303 to pass through the upper through hole 310 and lower through hole 307 to the bottom of lower fixing block 302. During penetration, mating plate 309 and magnetic suction piece 304 are engaged. The magnetic attraction is followed by the installation of the retaining ring 306 onto the insertion rod 303 via the thread 305, and then it is pressed against the bottom end of the lower fixing block 302. When the cover 2 is under pressure, the cover 2 will drive the insertion rod 303 to move downward, so that the insertion rod 303 compresses the anti-compression spring 308 through the magnetic attraction piece 304 and the docking plate 309. The anti-compression spring 308 buffers the pressure, thereby improving the compressive strength of the cover 2 and preventing the cover 2 from deforming and squeezing the internal cable under pressure, thus avoiding damage to the insulation layer or short circuit.

[0025] Furthermore, the upper fixing block 301 is welded to the insertion rod 303, the retaining ring 306 is connected to the insertion rod 303 by the thread 305, the lower fixing block 302 and the lower through hole 307 are integrally formed, and the mating plate 309 and the upper through hole 310 are integrally formed. When in use, the upper fixing block 301 is fixed to both sides of the cover 2, and the lower fixing block 302 is fixed to both sides of the box 1. When the cover 2 and the box 1 are closed, the components between the upper fixing block 301 and the lower fixing block 302 can provide pressure resistance to the cover 2.

[0026] Furthermore, the base 401 and the partition plate 402 are integrally formed. The first clamping plate 403 and the second clamping plate 404 are movably connected to the partition plate 402 and the base 401 through the limiting spring 405. When in use, the positioning component 4 can limit the first clamping plate 403 and the second clamping plate 404 through the limiting spring 405, which facilitates the clamping and fixing of the cable by the first clamping plate 403 and the second clamping plate 404. It can also facilitate the sorting and separation of the cable, avoid the cable from getting tangled, and facilitate subsequent maintenance.

[0027] Reference Figure 1 As shown, a fireproof inner layer 5 is fixedly installed on the inner wall of the frame box 1, a rubber pad 6 is provided in the middle of the frame cover 2, and a soft rubber column 7 is provided between the rubber pad 6 and the frame cover 2. The fireproof inner layer 5 is made of rock wool when in use, which can improve the fire resistance of the frame box 1.

[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0029] In use, the cable can be threaded onto the base 401. Then, the first clamp 403 and the second clamp 404 can be opened, compressing the limiting spring 405. The cable can then be placed between the first clamp 403 and the second clamp 404. Loosening the first clamp 403 and the second clamp 404 allows the limiting spring 405 to spring back and push the first clamp 403 and the second clamp 404 to clamp and fix the cable. The first clamp 403 and the second clamp 404 can separate the cable, facilitating cable management and preventing tangling, thus simplifying subsequent maintenance. The cover 2 can then be closed onto the box 1, with the rubber gasket 6 pressing against the box 1 and the cover 2. The insertion rod 303 can then be inserted through the upper through hole 310 and the lower through hole 301. 7. The rod passes through to the bottom of the lower fixing block 302. During the penetration, the mating plate 309 and the magnetic suction piece 304 are magnetically attracted. Then, the retaining ring 306 is installed on the insertion rod 303 through the thread 305 and pressed against the bottom end of the lower fixing block 302, thus completing the fixation between the cover 2 and the box 1. When the cover 2 is under pressure, the rubber pad 6 and the soft rubber column 7 can play a certain anti-compression effect to prevent the cover 2 and the box 1 from being squeezed and deformed. When under pressure, the cover 2 will drive the insertion rod 303 to move down, so that the insertion rod 303 compresses the anti-compression spring 308 through the magnetic suction piece 304 and the mating plate 309. The anti-compression spring 308 buffers the pressure, thereby improving the compressive strength of the cover 2 and preventing the cover 2 from deforming and squeezing the internal cable under pressure, thus avoiding damage to the insulation layer or short circuit.
