Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to a cable tray with a cable fixing function. Background Technology

[0002] Cable trays are structures used to support, protect, and organize cables. They are typically made of metal or plastic and have beams and support columns. They can span across the ceiling or walls of a building and are designed and used to provide a safe and reliable cable passage for moving cables from one location to another.

[0003] To prevent the cables laid inside from being easily moved, which could lead to loss of cable retention and damage to the insulation layer, existing cable trays typically rely on fixed limit seats or cable ties to limit and fix the position of the cables. However, once fixed limit seats or cable ties are fixed, they are difficult to adjust and are inconvenient to use.

[0004] For example, a cable tray disclosed in patent CN222366023U includes a cable tray body and a cover plate. The cable tray body has an adjustment mechanism inside. The adjustment mechanism includes an adjustment plate slidably installed between the inner walls of the left and right sides of the cable tray body. Three connecting rods are fixedly installed on the bottom outer wall of the adjustment plate. An upper limit seat is fixedly installed on the bottom outer wall of the connecting rod. A lower limit seat is fixedly installed on the bottom inner wall of the cable tray body. Although this patent sets up an adjustment mechanism and limit seats to achieve basic cable fixing, the position of the limit seats cannot be flexibly adjusted according to the actual cable layout requirements. In actual cable laying scenarios, the cable routing and branch positions are complex and diverse. Because the position of the limit seats is fixed, it is very easy for the fixing point to mismatch with the cable branch position. This leads to the cable having to be excessively bent during the laying process, which can cause serious damage to the cable.

[0005] Therefore, it is necessary to invent a cable tray with a cable fixing function to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cable tray with a cable fixing function, which solves the problem that the workpiece may be clamped to an asymmetrical position, and the lateral force generated during punching will cause the hole position to shift or the edge burrs to increase.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable tray with a cable fixing function, comprising a cable tray trough, wherein the cable tray trough is a U-shaped trough structure with an open top, and a cable tray cover plate is fitted on its top. Two cable fixing frames are provided at the bottom of the cable tray trough, each cable fixing frame including a lower frame and an upper frame arranged symmetrically. A position moving component is provided between the bottom of the cable fixing frame near the bottom of the cable tray trough and the cable tray trough, wherein the position moving component includes a fixed seat installed on the bottom surface inside the cable tray trough, and T-shaped sliding grooves are provided on the side walls on both sides of the fixed seat along the length direction. A T-shaped slider is slidably fitted inside the T-shaped sliding groove, and the top of the T-shaped slider is fixed to the bottom surface of the lower frame of the cable fixing frame. A disassembly and assembly component is provided between the two cable fixing frames.

[0008] Preferably, the lower frame is hinged to the upper frame on one side by a hinge, and the other side is detachably fastened by two symmetrically distributed latches.

[0009] Preferably, a semi-circular wire groove is provided at the corresponding position on the top surface of the lower frame and the bottom surface of the upper frame. The two semi-circular wire grooves are fastened together to form a circular wire fixing hole for a single cable to pass through, and a rubber anti-slip pad is pasted on the inner wall of the semi-circular wire groove.

[0010] Preferably, the position moving component further includes a limiting bolt that is threaded through the left and right sides of the lower frame of the cable holder. The screw end of the limiting bolt passes through the T-shaped slider and is screwed into the interior of the fixing seat. The side wall of the fixing seat has a plurality of equally spaced screw holes along the length of the T-shaped groove, and the screw holes are adapted to the limiting bolt.

[0011] Preferably, the assembly / disassembly assembly includes four insert rods and corresponding insertion holes. The insert rods are installed on the bottom surface of the lower frame of the cable holder on the side away from the position moving component, and the insertion holes are opened on the top surface of the upper frame of the cable holder on the side close to the position moving component. The insert rods can be inserted and removed into the insertion holes.

[0012] Preferably, the assembly and disassembly assembly further includes two symmetrically arranged adjustment plates, one end of which is hinged to the left and right side walls of the lower frame of the cable holder on the side away from the position moving assembly via a bearing seat.

[0013] Preferably, the other end of the adjusting plate is threaded with a limiting bolt II, and the left and right side walls of the upper frame of the fixed frame near the position moving component are provided with screw holes II that are adapted to the limiting bolt II, and the screw end of the limiting bolt II can be screwed into the screw hole II.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model, through the combined design of "cable holder + position moving component", achieves both stable cable fixing and flexible position adjustment capability: the cable holder is fastened to the upper frame by the lower frame and the circular fixing hole formed by the semi-circular cable groove independently limits the position of a single cable. With the rubber anti-slip pad on the inner wall of the cable groove, the insulation layer damage caused by the cable shaking and friction in the cable tray can be avoided; at the same time, the cable holder near the bottom of the cable tray groove can be adjusted along the length of the cable tray by sliding cooperation between the T-shaped slider and the T-shaped groove of the fixing seat. After adjustment, it is locked by the limiting bolt and the corresponding screw hole. The fixing point can be flexibly optimized according to the actual cable layout requirements, solving the problem that the traditional fixed cable fixing structure cannot adapt to changes in cable layout. 2. This utility model achieves multi-layer expansion and convenient assembly / disassembly of the cable tray through detachable assembly / disassembly components, adapting to the laying requirements of different cable quantities: the two cable trays are initially positioned by the insertion and removal of the plug and socket, and then fixed by the locking of the adjusting plate and the second limiting bolt and the second screw hole. This can stably assemble a double-layer cable tray structure, increasing the amount of cable laid per unit space of the cable tray; when the number of cables decreases, the second limiting bolt can be quickly removed, the plug can be pulled out, and the upper cable tray can be removed to return to the single-layer cable tray mode without modifying the cable tray body. Compared with traditional integrated multi-layer cable trays, this significantly improves the adaptability to different cable laying scenarios and reduces equipment modification and maintenance costs.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-6 The cable tray shown includes a cable tray trough 1, which is a U-shaped trough structure with an open top and a cable tray cover plate 2 covering the top. Two cable fixing frames 3 are provided at the bottom of the cable tray trough 1. Each cable fixing frame 3 includes a lower frame 301 and an upper frame 302 arranged symmetrically. The lower frame 301 and the upper frame 302 are hinged on one side by a hinge, and can be detachably fastened on the other side by two symmetrically distributed latches 303. A semi-circular wire groove 304 is provided at the corresponding position on the top surface of the lower frame 301 and the bottom surface of the upper frame 302. After the two semi-circular wire grooves 304 are fastened together, they form a circular cable fixing hole for a single cable to pass through. The inner wall of the semi-circular wire groove 304 is attached with a rubber anti-slip pad.

[0019] In this embodiment, the circular cable fixing hole formed by the interlocking of two semi-circular cable grooves 304 can firmly fix a single cable in the cable tray trough 1, preventing the cable from shaking or shifting within the cable tray, ensuring that the cables are arranged neatly and orderly, avoiding cable tangling and friction, reducing the risk of cable damage, and improving the safety and stability of cable use. Furthermore, the rubber anti-slip pads pasted on the inner wall of the semi-circular cable grooves 304 can increase the friction between the cable and the cable grooves 304, further preventing cable slippage; on the other hand, the rubber material has a certain degree of elasticity and softness, which can buffer the compression and vibration of the cable, protecting the cable sheath and extending the cable's service life.

[0020] A position moving component 4 is provided between the bottom of the cable tray 3 near the bottom of the cable tray trough 1 and the cable tray trough 1. The position moving component 4 includes a fixed seat 401 installed on the bottom surface inside the cable tray trough 1. T-shaped slide grooves 402 are opened along the length direction on the side walls of the fixed seat 401. T-shaped sliders 403 are slidably fitted inside the T-shaped slide grooves 402. The top of the T-shaped sliders 403 is fixed to the bottom surface of the lower frame 301 of the cable tray 3. A disassembly and assembly component 5 is provided between the two cable trays 3. The position moving component 4 also includes a limiting bolt 404 threaded through the left and right sides of the lower frame 301 of the cable tray 3. The screw end of the limiting bolt 404 passes through the T-shaped slider 403 and is screwed into the fixed seat 401. Multiple equally spaced screw holes 405 are opened along the length direction of the T-shaped slide grooves 402 on the side walls of the fixed seat 401. The screw holes 405 are adapted to the limiting bolts 404.

[0021] In this embodiment, the sliding engagement of the T-shaped groove 402 and the T-shaped slider 403 allows the cable holder 3 near the bottom of the cable tray trough 1 to move freely along the length direction on the fixed seat 401. This allows for flexible adjustment of the position of the cable holder 3 according to the actual cable laying situation, making the cable fixing more reasonable and improving the utilization rate of the internal space of the cable tray. When the cable holder 3 moves to the appropriate position, the T-shaped slider 403 can be firmly fixed in the T-shaped groove 402 by screwing the screw end of the limiting bolt 404 into the corresponding screw hole 405 on the fixed seat 401. This accurately fixes the position of the cable holder 3, preventing it from moving during use and ensuring the stability of the cable fixing. The multiple equidistant screw holes 405 provide more fixing position options, further improving the accuracy of position adjustment.

[0022] The disassembly and assembly component 5 includes four insert rods 501 and corresponding insertion holes 502. The insert rods 501 are installed on the bottom surface of the lower frame 301 of the cable holder 3 on the side away from the position moving component 4. The insertion holes 502 are opened on the top surface of the upper frame 302 of the cable holder 3 on the side close to the position moving component 4, and the insert rods 501 can be inserted and removed into the insertion holes 502. The disassembly and assembly component 5 also includes two symmetrically arranged adjustment plates 503. One end of the adjustment plate 503 is hinged to the left and right side walls of the lower frame 301 of the cable holder 3 on the side away from the position moving component 4 through a shaft seat. The other end of the adjustment plate 503 is threaded with a second limiting bolt 504. The left and right side walls of the upper frame 302 of the cable holder 3 on the side close to the position moving component 4 are provided with screw holes 505 that are adapted to the second limiting bolt 504. The screw end of the second limiting bolt 504 can be screwed into the screw hole 505.

[0023] In this embodiment, the plug-in and plug-out design of the plug rod 501 and the socket 502 allows for quick connection and separation between the two cable trays 3. During installation, inserting the plug rod 501 into the socket 502 initially positions the two cable trays 3 together. During disassembly, simply pulling out the plug rod 501 easily separates the two cable trays 3. This design greatly improves the efficiency of assembly and disassembly of the cable trays 3, facilitating overall layout adjustments or partial replacements of cables within the cable tray. Furthermore, through the cooperation of the adjusting plate 503 and the second limiting bolt 504, after the plug rod 501 is inserted into the socket 502, rotating the adjusting plate 503 around the shaft seat aligns the second limiting bolt 504 with the second screw hole 505. Then, tightening the second limiting bolt 504 and screwing its screw end into the second screw hole 505 securely connects the two cable trays 3 together, preventing separation during use and ensuring the reliability of cable fixing.

[0024] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-6When using this utility model, firstly, adjust the position of the cable holder 3 to a suitable position according to the requirements of the cable laying location. Then, rotate the limiting bolts 404 on the left and right sides of the lower frame 301 of the cable holder 3 near the bottom of the cable tray trough 1. Unscrew the limiting bolts 404 from the screw holes 405 on the side wall of the fixing seat 401, so that the screw end of the limiting bolt 404 no longer penetrates the T-shaped slider 403 and is screwed into the fixing seat 401. At this time, the T-shaped slider 403 can slide freely in the T-shaped groove 402. Gently push the cable holder by hand... The cable tray 3 moves along the length of the fixed seat 401 via the T-shaped slider 403 and the T-shaped groove 402. This allows the cable tray 3 to be moved to a suitable position according to the actual cable laying situation, so as to make the cable fixing more reasonable and improve the utilization rate of the internal space of the cable tray. When the cable tray 3 is moved to a suitable position, the screw hole 405 corresponding to the current position is selected, and the screw end of the limit bolt 404 is passed through the T-shaped slider 403 and screwed into the screw hole 405, thereby fixing the position of the cable tray 3. Then, unlock the latch 303, open the upper frame 302, carefully place the single cable to be fixed into the semi-circular cable groove 304 on the top surface of the lower frame 301, slowly rotate the upper frame 302 around the hinge to close it, so that the semi-circular cable groove 304 on the bottom surface of the upper frame 302 and the semi-circular cable groove 304 on the top surface of the lower frame 301 are engaged to form a complete circular cable fixing hole. Then, engage the two latches 303 on the other side of the upper frame 302 and the lower frame 301 to securely fix the cable therein. Finally, when it is necessary to stack the height of the cable tray 3, place another cable tray 3 to be installed in a suitable position, and insert the four insert rods 501 on its bottom surface into the four insert holes 502 of the bottom cable tray 3 to achieve the initial positioning and connection of the two cable trays 3. Then, rotate the adjusting plate 503 around the shaft seat to align the second limit bolt 504 with the second screw hole 505 and tighten it, so that the two cable trays 3 will be firmly connected together to prevent the two cable trays 3 from separating during use. In this way, the installation of multi-layer cable trays 3 can be completed.
