Description

Technical Field

[0001] This utility model relates to the field of fireproof cable tray technology, and in particular to a fireproof cable tray that is easy to disassemble and install. Background Technology

[0002] Fire-resistant cable trays are made by spraying a layer of fire-retardant paint onto the surface of ordinary cable trays to achieve a fire-retardant effect. The cable trays themselves do not catch fire; only the cables themselves are susceptible to fire. The fire-retardant paint works by preventing fire. Fire-resistant cable trays are mainly composed of fire-resistant boards made of fiberglass reinforcement and inorganic adhesives, combined with a metal frame and other fire-resistant substrates. They are typically assembled from multiple sections and fixed to the wall using specialized brackets.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Fireproof Cable Tray that is Easy to Disassemble and Install," with publication (announcement) number "CN214958478U." This patent mainly controls the rotation of a rotating rod to allow it to be inserted into or detached from the fixing groove on the fixing block. Moreover, the stop bar can both prevent the rotating rod from detaching from the fixing groove and allow it to be detached from the rotating rod by rotation, ultimately achieving quick assembly and disassembly between the cable tray body and the mounting bracket. However, the mounting bracket in this device cannot be adjusted, making it unsuitable for various specifications of cable trays or complex construction environments, such as uneven ceilings. It also requires the manufacture of various models of fixing brackets for different specifications of cable trays. Therefore, we propose a fireproof cable tray that is easy to disassemble and install. Utility Model Content

[0004] The purpose of this utility model is to provide a fireproof cable tray that is easy to disassemble and install, in order to solve the problem mentioned in the background art that the mounting brackets are not adjustable, cannot adapt to various specifications of cable trays or cope with complex construction environments, such as uneven ceilings, and require the manufacture of various models of fixing brackets for different specifications of cable trays.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof cable tray that is easy to disassemble and install, comprising a cable tray, an installation structure, and a fixing structure. The cable tray is connected through the installation structure, and the cable tray is installed on the fixing structure. The fixing structure includes a first fixing frame and a second fixing frame. The second fixing frame is slidably connected to the first fixing frame through a first sliding groove. The first fixing frame is threadedly mounted with a screw through a threaded seat. A fixing plate is fixedly mounted at the bottom end of the second fixing frame. The screw is rotatably connected to the fixing plate. Connecting rods are slidably mounted on the first fixing frame and the second fixing frame respectively. The side wall of the connecting rod is provided with several limiting holes. Fastening bolts are threadedly mounted on the side walls of the first fixing frame and the second fixing frame. A connecting plate is fixedly mounted at the top end of the connecting rod.

[0006] As a preferred embodiment, the installation structure includes a connecting sleeve, a plug, and a fixing block. The connecting sleeve is fixedly installed at both ends of the cable tray, and the interior of the connecting sleeve is set as a cavity. The plug is fixedly installed at both ends of the cable tray by the fixing block, with the plug at the end away from the connecting sleeve, and the connecting sleeve and the plug cooperate with each other.

[0007] As a preferred embodiment, a first spring is fixedly installed inside the cavity of the connecting sleeve, and a sliding plate is fixedly installed at the other end of the first spring. The sliding plate is slidably connected to the inner wall of the connecting sleeve. Limiting grooves are respectively provided at the top and bottom of the connecting sleeve, and mounting grooves are respectively provided at the top and bottom of the insertion post. The mounting grooves and limiting grooves are matched. A second spring is fixedly installed in the mounting groove, and a telescopic post is fixedly installed at the other end of the second spring. The telescopic post is slidably connected to the mounting groove and the limiting groove respectively.

[0008] As a preferred embodiment, the first slide groove is formed on the first fixed frame, the second fixed frame extends into the first slide groove, the threaded seat is fixedly installed at the bottom end of the first fixed frame, the screw is threadedly installed on the threaded seat, one end of the screw is fixedly installed on the turntable, and the end of the screw away from the turntable extends into the fixed plate.

[0009] As a preferred embodiment, the first fixing bracket and the second fixing bracket are respectively fixedly installed on the side away from the threaded seat.

[0010] As a preferred embodiment, the first fixing frame and the second fixing frame are respectively provided with a second sliding groove, the connecting rod is slidably installed in the second sliding groove, and the fastening bolt is engaged with the limiting hole.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the fixed structure, the second fixing bracket slides within the first fixing bracket by rotating the screw according to the width of the cable tray, thereby adjusting the width between the second and first fixing brackets to meet the installation requirements of various cable tray specifications. When the connecting rod is installed on the ceiling via the connecting plate, the width between the second and first fixing brackets no longer needs adjustment, preventing the cable tray from loosening or shifting due to external forces or vibrations during use, thus enhancing the stability of the overall structure. By tightening the bolts, the first and second fixing brackets slide on the connecting rod, thereby adjusting the height of the first and second fixing brackets. This is suitable for different installation scenarios, such as uneven ceilings, ensuring that the support plate always remains on the same horizontal plane, reducing the need for fixing brackets of different specifications.

[0013] 2. In the designed installation structure, the insert column slides in the connecting sleeve. When the telescopic column moves into the limiting groove, it automatically pops out to the outside of the connecting sleeve under the elastic force of the second spring, thereby limiting and fixing the insert column and the connecting sleeve, thus connecting and assembling the cable tray. The automatic pop-out function of the second spring can ensure that the limiting groove firmly locks the telescopic column, preventing the cable tray from detaching from the connection under external force, improving the safety of the overall structure, reducing complex bolt tightening or welding steps, and making it suitable for rapid assembly and disassembly. The cable tray can be quickly replaced according to construction needs. Attached Figure Description

[0020] 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. Example 1

[0021] Please see the appendix Figure 1 - Appendix Figure 3A fireproof cable tray that is easy to disassemble and install includes a cable tray 1, an installation structure 2, and a fixing structure 3. The cable tray 1 is connected via the installation structure 2 and mounted on the fixing structure 3. The installation structure 2 includes a connecting sleeve 21, a pin 22, and a fixing block 23. The connecting sleeve 21 is fixedly installed at both ends of the cable tray 1, and the interior of the connecting sleeve 21 is set as a cavity. The pin 22 is fixedly installed at both ends of the cable tray 1 via the fixing block 23, with the pin 22 located at the end furthest from the connecting sleeve 21. The connecting sleeve 21 and the pin 22 cooperate with each other to connect... A first spring 24 is fixedly installed inside the cavity of sleeve 21. A sliding plate 25 is fixedly installed at the other end of the first spring 24. The sliding plate 25 is slidably connected to the inner wall of the connecting sleeve 21. Limiting grooves 29 are respectively provided at the top and bottom ends of the connecting sleeve 21. Mounting grooves 26 are respectively provided at the top and bottom ends of the insert post 22. The mounting grooves 26 and the limiting grooves 29 are matched. A second spring 27 is fixedly installed inside the mounting groove 26. A telescopic post 28 is fixedly installed at the other end of the second spring 27. The telescopic post 28 is slidably connected to the mounting groove 26 and the limiting groove 29 respectively.

[0022] Specifically, when the insert post 22 slides to the limiting groove 29, the telescopic post 28 automatically pops out and locks under the action of the second spring 27, thereby fixing the insert post 22 and the connecting sleeve 21, quickly completing the connection of the cable tray 1. The automatic pop-out function ensures stability, prevents external force from causing it to fall off, improves safety, and eliminates the need for fastening or welding. It is convenient for quick assembly, disassembly and replacement of the cable tray 1, and adapts to various construction needs. Example 2

[0023] Please see the appendix Figure 4 and attached Figure 5 The fixing structure 3 includes a first fixing frame 301, a second fixing frame 302, and a first sliding groove 303. The first sliding groove 303 is formed on the first fixing frame 301. The second fixing frame 302 extends into the first sliding groove 303 and is slidably connected to the first fixing frame 301 through the first sliding groove 303. A threaded seat 304 is fixedly installed at the bottom end of the first fixing frame 301. A screw 305 is threaded onto the threaded seat 304. A turntable is fixedly installed at one end of the screw 305. A fixing plate 306 is fixedly installed at the bottom end of the second fixing frame 302. The end of the screw 305 away from the turntable extends into the fixing plate 306. 5 is rotatably connected to the fixing plate 306. The first fixing frame 301 and the second fixing frame 302 are respectively fixedly installed on the side away from the threaded seat 304. The first fixing frame 301 and the second fixing frame 302 are respectively provided with the second sliding groove 308. The first fixing frame 301 and the second fixing frame 302 are slidably installed with the connecting rod 309 through the second sliding groove 308. The side wall of the connecting rod 309 is provided with a plurality of limiting holes 310. The top side wall of the first fixing frame 301 and the second fixing frame 302 is threaded with fastening bolts 311. The fastening bolts 311 cooperate with the limiting holes 310. The top of the connecting rod 309 is fixedly installed with the connecting plate 312.

[0024] Specifically, the width of the first fixing bracket 301 and the second fixing bracket 302 can be adjusted by screw 305 to adapt to various specifications of cable tray 1. The width of the connecting rod 309 cannot be adjusted after it is fixed to prevent loosening due to external force or vibration and improve structural stability. The fastening bolt 311 can adjust the height of the first fixing bracket 301 and the second fixing bracket 302 to adapt to different installation scenarios, such as uneven ceilings, to ensure that the support plate 307 remains at the same level and reduce the need for multiple specifications of fixing brackets.

[0025] The working principle of this utility model is as follows: This utility model is a fireproof cable tray that is easy to disassemble and install. Based on the width of the cable tray 1, the turntable is rotated, which drives the screw 305 to rotate. The screw 305 moves threadedly in the threaded seat 304, thereby moving the fixing plate 306. The fixing plate 306 then drives the second fixing bracket 302 to slide within the first fixing bracket 301, thus adjusting the distance between the first fixing bracket 301 and the second fixing bracket 302. This allows the cable tray 1 to be installed between the first fixing bracket 301 and the second fixing bracket 302. The connecting plate 312 is then fixed to the ceiling. The distance between the first fixed frame 301 and the second fixed frame 302 is no longer adjusted. Loosen the fastening bolt 311 so that it disengages from the limiting hole 310, thereby releasing the limiting position of the connecting rod 309. This allows the first fixed frame 301 and the second fixed frame 302 to slide on the connecting rod 309. When the first fixed frame 301 and the second fixed frame 302 have slid to the appropriate position, tighten the fastening bolt 311 so that it extends into the limiting hole 310, thereby re-limiting the connecting rod 309 and adjusting the height of the first fixed frame 301 and the second fixed frame 302.

[0026] The cable tray 1 is installed between the first fixed frame 301 and the second fixed frame 302, and the cable tray 1 is in contact with the support plate 307. The support plate 307 supports the cable tray 1. The insert 22 on the cable tray 1 is inserted into the connecting sleeve 21 of the other cable tray. The insert 22 abuts against the slide plate 25, pressing the telescopic column 28. The telescopic column 28 compresses the second spring 27, causing the telescopic column 28 to retract into the mounting groove 26, thereby extending the telescopic column 28 into the connecting sleeve 21. This pushes the cable tray 1, causing the insert 22 to slide inside the connecting sleeve 21. At the same time, the slide plate 25 compresses the first spring 24, which buffers the slide plate 25. When the telescopic column 28 moves to the position of the limiting groove 29, the telescopic column 28 automatically resets under the elastic force of the second spring 27, causing the telescopic column 28 to pop out of the connecting sleeve 21. The telescopic column 28 limits and fixes the insert 22 and the connecting sleeve 21, thereby assembling the cable tray 1 for easy installation and disassembly.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
