Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a modular cable tray designed to prevent loosening. Background Technology

[0002] Cable trays are rigid metal or non-metal structures made of trays, ladders, etc., and are made of materials such as steel, aluminum alloy, and fiberglass. They come in tray-type, ladder-type, and trough-type structures, and can support and protect cables, arranging them in an orderly manner for easy installation and maintenance. They can also shield electromagnetic interference and are widely used in cable laying projects in the power and communication fields. Modular cable trays are cable laying devices that are flexibly assembled from standardized straight-section trays. They can adjust the length, angle, and direction as needed without special accessories. They have advantages such as convenient installation, compact structure, and strong compatibility, and are suitable for complex cable layouts or scenarios that require frequent modifications, such as buildings, industries, and data centers.

[0003] Existing modular cable trays typically use multiple sets of fastening bolts at the connection points to prevent them from falling off, thus ensuring stable fixation. However, while achieving a rigid fixation effect through fastening bolts, this also makes it inconvenient to disassemble and reassemble the cable tray later. Furthermore, the various specifications of cable trays on the market require suitable connection structures during installation, which not only increases production costs but also reduces the convenience of installation and affects the efficiency of later maintenance. Therefore, we propose a modular cable tray with anti-loosening design. Utility Model Content

[0004] The main purpose of this utility model is to provide a modular cable tray that prevents loosening, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular cable tray with anti-loosening features, comprising a tray body, a suspension connecting rod, and a ceiling connecting fixing strip. The tray body is detachably fitted with a fixing component. Suspension connecting rods are rotatably connected to the top of both sides of the fixing component. A nesting hole adapted to the suspension connecting rod is provided at the center of the ceiling connecting fixing strip. The suspension connecting rod passes through the nesting hole from bottom to top through the ceiling connecting fixing strip and extends to the top of the ceiling connecting fixing strip. A limiting head is fixedly connected to the top of the suspension connecting rod, and the lower surface of the limiting head is attached to the upper surface of the ceiling connecting fixing strip.

[0006] Preferably, the fixing component includes a U-shaped support frame, the bottom of the inner cavity of the U-shaped support frame is provided with a first limiting component, and the two sides of the inner cavity of the U-shaped support frame are provided with second limiting components.

[0007] Preferably, the first limiting component includes a sliding groove, an L-shaped locking block, a driving screw, and a hand-tightening end. The sliding groove is laterally opened on the bottom surface of the inner cavity of the U-shaped support frame. The driving screw is laterally rotatably mounted in the inner cavity of the sliding groove. The L-shaped locking blocks are slidably mounted on both sides of the upper surface of the sliding groove, and the bottom ends of the L-shaped locking blocks are threaded to the surface of the driving screw. The hand-tightening end is rotatably nested on one side of the U-shaped support frame and at a position corresponding to the driving screw, and the inner side of the hand-tightening end is fixedly connected to one side of the driving screw.

[0008] Preferably, the second limiting component includes an adjusting groove, an adjusting screw, a connecting slider, and an upper limit plate. The U-shaped bearing frame has adjusting grooves vertically opened on both sides of its inner cavity. The adjusting grooves are rotatably equipped with adjusting screws, and the top of the adjusting screws is fixedly connected to the bottom of the suspension connecting rod. Connecting sliders are threadedly connected to corresponding positions on the surfaces of the adjusting screws on both sides. The upper limit plate is fixedly connected to the outer wall of the connecting slider.

[0009] Preferably, the drive screw is a double-threaded screw, and the two ends of the double-threaded screw surface are provided with opposing threads.

[0010] Preferably, the suspension connecting rod includes an upper connecting pipe, a connecting screw, and a lower connecting pipe. The lower connecting pipe is rotatably provided on both sides of the top end of the U-shaped support frame, and the lower connecting pipe passes through the top end of the U-shaped support frame and extends to the inner cavity of the adjusting slide groove and is fixedly connected to the top end of the adjusting screw. The upper end of the inner cavity of the upper connecting pipe is threadedly connected to the connecting screw, and the upper connecting pipe is threadedly connected to the upper surface of the connecting screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes the cooperation of the first and second limiting components. During the installation of the cable tray body, the L-shaped locking blocks on both sides can be moved in opposite directions or backwards by rotating the hand-tightening end according to the size of the cable tray body, quickly adapting to the width limiting of different specifications of cable tray bodies. At the same time, the adjusting screw in the sliding groove can be rotated through the suspension connecting rod, thereby moving the connecting slider and the upper limit plate on the outside of the connecting slider up and down, thus achieving vertical fixation of the cable tray body. This forms a dual adjustable limiting structure in both horizontal and vertical directions, which can accurately fix cable trays of different sizes and prevent the cable tray from shaking or loosening, effectively improving installation adaptability and connection stability. Moreover, quick disassembly and assembly can be achieved by reversing the operation, effectively reducing the difficulty of later inspection and maintenance and improving the practical effect of the cable tray.

[0013] 2. The upper connecting pipe, connecting screw, and lower connecting pipe of this utility model cooperate with each other. Therefore, during installation, the connecting screw can be moved up and down inside the upper or lower connecting pipe by rotating the upper or lower connecting rod, thereby adjusting the distance between the upper and lower connecting rods and thus changing the length of the suspension connecting rod to adapt to the installation needs of ceilings with different floor heights. No complicated tools are required to complete the height fine adjustment and quick disassembly and assembly, further improving the convenience of cable tray installation. Attached Figure Description

[0019] 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.

[0020] Example

[0021] Please see Figure 1 - Figure 4The diagram shows a modular cable tray designed to prevent loosening, comprising a tray body 1, a suspension connecting rod 3, and a ceiling connecting fixing strip 4. The tray body 1 is detachably fitted with a fixing component 2. Suspension connecting rods 3 are rotatably connected to the top of both sides of the fixing component 2. The ceiling connecting fixing strip 4 has a nesting hole 11 at its center that matches the suspension connecting rod 3. The suspension connecting rod 3 passes through the nesting hole 11 from bottom to top through the ceiling connecting fixing strip 4 and extends to the top of the ceiling connecting fixing strip 4. A limiting head 5 is fixedly connected to the top of the suspension connecting rod 3, and the lower surface of the limiting head 5 is in contact with the upper surface of the ceiling connecting fixing strip 4. The tray body 1 is connected to the suspension connecting rod 3 through the detachable fixing component 2. The suspension connecting rod 3 passes through the nesting hole 11 on the ceiling connecting fixing strip 4, and the top limiting head 5 is in contact with the upper surface of the fixing strip, thus achieving a stable suspension installation of the tray body 1 to the ceiling.

[0022] The fixing component 2 includes a U-shaped support frame 21. A first limiting component is provided at the bottom of the inner cavity of the U-shaped support frame 21, and second limiting components are provided on both sides of the inner cavity of the U-shaped support frame 21. The first limiting component includes a sliding groove 8, an L-shaped locking block 10, a driving screw 9, and a hand-tightening end 7. A sliding groove 8 is laterally formed on the bottom surface of the inner cavity of the U-shaped support frame 21. The driving screw 9 is laterally rotatably mounted inside the sliding groove 8. L-shaped locking blocks 10 are slidably mounted on both sides of the upper surface of the sliding groove, and the bottom ends of the L-shaped locking blocks 10 are threadedly connected to the surface of the driving screw 9. A hand-tightening end 7 is rotatably nested on one side of the U-shaped support frame 21 at a position corresponding to the driving screw 9, and the inner side of the hand-tightening end 7 is fixedly connected to one side of the driving screw 9. The second limiting component includes an adjusting groove 22, an adjusting screw 23, a connecting slider 24, and an upper limit plate 6. Adjusting grooves 22 are vertically formed on both sides of the inner cavity of the U-shaped support frame 21. The inner cavity of the slide groove 22 is rotatably equipped with adjusting screws 23, and the top of the adjusting screws 23 is fixedly connected to the bottom of the suspension connecting rod 3. The corresponding positions on the surfaces of the adjusting screws 23 on both sides are threaded with connecting sliders 24. The outer wall of the connecting sliders 24 is fixedly connected with an upper limit plate 6. The driving screw 9 is a double-threaded screw, and the two ends of the double-threaded screw surface are provided with opposing threads. The double-threaded driving screw 9 of the first limiting component, together with the hand-tightening end 7, can synchronously adjust the L-shaped blocks on both sides to achieve rapid and accurate horizontal positioning of the cable tray. The second limiting component, through the transmission of the adjusting screws 23 and the connecting sliders 24, drives the upper limit plate 6 to move up and down to complete the stable clamping in the vertical direction. The two cooperate with each other to form a three-dimensional adjustable limiting structure, which can flexibly adapt to the installation requirements of different specifications of cable trays, and can provide a lasting and stable fixing force through threaded fastening, effectively preventing the cable tray from shaking and shifting, and greatly improving installation efficiency and reliability.

[0023] The suspension connecting rod 3 includes an upper connecting pipe 31, a connecting screw 32, and a lower connecting pipe 33. The lower connecting pipe 33 is rotatably provided on both sides of the top end of the U-shaped support frame 21. The lower connecting pipe 33 passes through the top end of the U-shaped support frame 21 and extends to the inner cavity of the adjusting slide groove 22, where it is fixedly connected to the top end of the adjusting screw 23. The upper end of the inner cavity of the upper connecting pipe 31 is threadedly connected to the connecting screw 32, and the upper end surface of the connecting screw 32 is threadedly connected to the upper connecting pipe 31. The suspension connecting rod 3, through the threaded engagement of the upper connecting pipe 31, the connecting screw 32, and the lower connecting pipe 33, allows for flexible adjustment of the overall length of the suspension connecting rod 3 by rotating either the upper connecting pipe 31 or the lower connecting pipe 33. This enables quick adaptation to the installation requirements of ceilings with different heights without the need for tools, achieving precise fine-tuning of the height of the cable tray body 1 and convenient disassembly and assembly, significantly improving installation efficiency and environmental adaptability.

[0024] It should be noted that this utility model is a modular cable tray designed to prevent loosening. During installation of the cable tray body 1, first, according to the dimensions of the cable tray body 1, rotate the hand-tightening end 7 to drive the drive screw 9 to rotate. Utilizing the double-threaded structure, the L-shaped locking blocks on both sides move synchronously towards or away from each other, completing the horizontal width limit of the cable tray body 1. Then, rotate the suspension connecting rod 3, which drives the adjusting screw 23 to rotate within the adjusting groove 22 via the lower connecting pipe 33. This causes the connecting slider 24 to move up and down along the screw, thereby adjusting the position of the upper limit plate 6 and achieving vertical positioning of the cable tray body 1. The fixed direction forms a dual adjustable limit in both horizontal and vertical directions, ensuring stable installation and adaptability to different sizes of cable trays. During suspension installation, the position of the connecting screw 32 within the upper or lower connecting pipe 33 can be adjusted by rotating the upper connecting pipe 31 or the lower connecting pipe 33, thereby changing the overall length of the suspension connecting rod 3 to adapt to ceilings of different heights. Conversely, the above steps can be reversed to quickly disassemble the cable tray body 1, facilitating later inspection and maintenance. This achieves flexible installation, precise fixing, and convenient disassembly of the cable tray, effectively improving its adaptability, stability, and practicality.
