Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a retractable cable tray that prevents cable displacement. Background Technology

[0002] Cable trays are crucial infrastructure in modern building electrical systems and industrial engineering, used to support, protect, and manage various cables. They are widely used in power, telecommunications, rail transportation, petrochemicals, and large public facilities. Their main function is to lay cables systematically along designated paths, providing mechanical protection, electromagnetic shielding, fire resistance, and facilitating future maintenance and expansion. With the increasing complexity of building structures and the diversification of electricity demands, cable laying environments are becoming increasingly varied, placing higher demands on the installation flexibility, spatial adaptability, and operational safety of cable trays. Especially in confined spaces, non-standard spacing, or situations requiring later adjustments, extendable cable trays demonstrate significant advantages due to their width adjustment capabilities, becoming an effective solution to on-site installation challenges.

[0003] Utility model patent CN217656355U discloses a telescopic adjustable cable tray. Although the device has the function of adjusting the width of the cable tray through adjusting screws and adjusting sleeves, it adopts a structure design with multiple screws linked together. That is, all adjusting screws must be rotated at the same time to achieve the overall telescopic movement, which leads to significant defects in actual operation. Since all screws need to rotate synchronously, the operator must apply force one by one or with multiple tools at the same time, which is cumbersome, time-consuming and labor-intensive, especially inconvenient when working at height or in confined spaces. This structure cannot achieve local fine adjustment or independent adjustment on one side. When the cable tray is subjected to uneven force on both sides or there is a deviation in the installation base, it is difficult to perform precise alignment and stress compensation, which can easily cause the cable tray to twist, the connection parts to loosen, and affect the overall structural stability.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a retractable cable tray that prevents cable displacement to solve this problem. This new type of cable tray should significantly improve the flexibility and efficiency of installation and adjustment, reduce operational complexity, and better meet the demands of modern electrical engineering for high adaptability, high reliability, and convenient maintenance, thus providing strong support for the safe and stable operation of cable systems. Utility Model Content

[0005] The purpose of this invention is to provide a retractable cable tray that prevents cable displacement. This solves the problems of existing technologies where all screws need to rotate synchronously, requiring operators to apply force individually or with multiple tools simultaneously. This is cumbersome, time-consuming, and labor-intensive, especially inconvenient when working at heights or in confined spaces. Furthermore, the existing structure cannot achieve local fine-tuning or independent adjustment on one side. When the cable tray is subjected to uneven force on both sides or there are deviations in the installation base, it is difficult to achieve precise alignment and stress compensation, which can easily cause the cable tray to twist, the connection parts to loosen, and affect the overall structural stability.

[0006] To achieve the above objectives, this utility model provides a retractable cable tray to prevent cable displacement, including a bottom frame and two side cable trays respectively arranged on both sides of the top of the bottom frame. Both ends of the bottom frame are fixedly connected to mounting rods, and both ends of the mounting rods are fixedly connected to mounting brackets. The bottom frame is provided with sliding rods on both sides. The sliding rods are connected to the side wall of the bottom frame through several sliding structures. The top of the sliding rods is detachably connected to the bottom of the side bridge. A positioning structure is provided on one side of the bottom of the sliding rod. The positioning structure is detachably connected to the adjacent sliding structure. A protective net cover is provided on the top of the two side cable trays. The two sides of the protective net cover are detachably connected to the side walls of the adjacent side cable trays.

[0007] The sliding rod has several sliding grooves on one side, and the sliding structure includes a guide rod that slides with the sliding grooves. One end of the guide rod is connected to the side wall of the bottom frame.

[0008] The protective netting has several suspension rings connected to both sides, and the suspension rings are detachably connected to the side wall of the side cable tray.

[0009] The positioning structure includes a positioning screw with one end threaded through the sliding rod, and the bottom of the guide rod has several positioning holes that are adapted to the positioning screw.

[0010] The side wall of the side bridge is fixedly connected with several connecting columns adapted to the suspension ring, and one end of the connecting column is fixedly connected to a limiting circular plate.

[0011] The side bridge is connected to the top of the sliding rod by several connecting screws, and a blocking plate is fixedly connected to one end of each guide rod.

[0012] This utility model discloses a retractable cable tray designed to prevent cable displacement. By incorporating sliding rods on both sides of the bottom frame and a sliding structure, it achieves independent sliding adjustment of the side cable tray relative to the bottom frame. This overcomes the shortcomings of existing technologies that require simultaneous rotation of multiple screws to achieve extension and retraction. It eliminates the need for multiple tools or simultaneous operation at multiple points, significantly reducing adjustment difficulty and labor intensity, making it particularly suitable for environments where operation is inconvenient, such as high altitudes or confined spaces. The sliding structure provides stable guidance for the sliding rods, ensuring smooth and unobstructed operation of the side cable tray during extension and retraction. The positioning structure can quickly lock with the sliding structure at any adjustment position, enabling adjustment on one side or in a partial manner. Independent positioning allows for precise alignment and stress release when uneven stress occurs on one side of the cable tray or when there are deviations in the mounting base. This avoids structural distortion or loosening of connections caused by forced symmetrical adjustment, improving installation adaptability and structural stability. The mounting rods and brackets at both ends of the bottom frame ensure that the cable tray is firmly fixed to the supporting structure, providing a reliable load-bearing foundation for the entire system. The protective mesh cover is detachably connected to the top of the side cable tray, which not only enhances the overall integrity of the cable tray and prevents cables from shifting laterally or jumping out of the cable tray due to vibration or external forces, but also improves the level of safety protection and reduces the risk of cable wear and external damage.

Sliding rods 4 are provided on both sides of the bottom frame 1. The sliding rods 4 are connected to the side wall of the bottom frame 1 through several sliding structures. The top of the sliding rods 4 is detachably connected to the bottom of the side bridge 2. A positioning structure is provided on one side of the bottom of the sliding rod 4. The positioning structure is detachably connected to the adjacent sliding structure. A protective net cover 5 is provided on the top of the two side cable trays 2. The two sides of the protective net cover 5 are detachably connected to the side walls of the adjacent side cable trays 2 respectively.

[0022] Workflow: When installing this retractable cable tray to prevent cable displacement, firstly, the mounting brackets 3 at both ends of the bottom frame 1 are fixed to the wall, bracket, or embedded parts using mounting rods to achieve initial positioning of the main body of the cable tray. Then, according to the width of the passageway or the cable laying requirements, the two side cable trays 2 are adjusted laterally. During adjustment, a sliding structure guides the sliding rod 4 to slide horizontally along the side wall of the bottom frame 1. The top of the sliding rod 4 is detachably connected to the side cable tray 2 using bolts or clips, allowing the side cable tray 2 to move synchronously with the sliding rod 4, thus achieving flexible expansion and contraction of the overall width of the cable tray. After adjusting to a suitable width, the sliding rod 4 is then... The positioning structure on one side of the bottom is detachably connected to the adjacent sliding structure: for example, by inserting positioning pins or locking bolts into preset holes, the position of the sliding rod 4 and the side cable tray 2 is fixed to prevent the side cable tray from retracting or shifting due to vibration or external force during subsequent cable laying or operation; after the main body of the cable tray is adjusted and locked, the protective net cover 5 is covered on the top of the two side cable trays 2, and its two sides are fixed to the side wall of the side cable tray 2 respectively by a detachable connection method: such as buckles or screws, forming a closed protective structure to effectively prevent foreign objects from falling in or personnel from accidentally touching the cable; finally, the cable is laid in an orderly manner in the bottom frame 1 to complete the installation of the entire cable tray system. Example 2

[0023] Please see Figure 1-5As shown in the figure, in this embodiment of a retractable cable tray for preventing cable displacement, a plurality of sliding grooves 8 are provided on one side of the sliding rod 4. The sliding structure includes a guide rod 12 that slides in cooperation with the sliding groove 8. One end of the guide rod 12 is connected to the side wall of the bottom frame 1. Specifically, through the sliding groove 8 and the guide rod 12 sliding in cooperation, one end of the guide rod 12 is fixed to the side wall of the bottom frame 1, and the sliding rod 4 slides horizontally along the guide rod 12 in the sliding groove 8, so as to realize the smooth guidance of the sliding rod 4 during the extension and retraction process, and achieve the effect of preventing the side cable tray 2 from deviating or jamming when moving and ensuring smooth adjustment.

[0024] The positioning structure includes a positioning screw 6 with one end threaded through the sliding rod 4. The bottom of the guide rod 12 has several positioning holes that are adapted to the positioning screw 6. Specifically, by the positioning screw 6 threaded through the sliding rod 4 and cooperating with the multiple positioning holes at the bottom of the sliding rod 4, rotating the positioning screw 6 so that its end is inserted into the corresponding positioning hole can lock the sliding rod 4 in different positions, thus achieving the effect of quick and reliable fixation after the width of the side cable tray 2 is adjusted.

[0025] The side cable tray 2 is connected to the top of the sliding rod 4 by several connecting screws 7. Each guide rod 12 has a baffle plate 11 fixedly connected to one end. Specifically, the connection between the side cable tray 2 and the top of the sliding rod 4 by the connecting screws 7 enables detachable fixing between the two, which facilitates the disassembly, assembly and adjustment of the side cable tray 2. At the same time, the baffle plate 11 is fixed to one end of the guide rod 12 to limit the sliding stroke of the sliding rod 4 and prevent it from detaching from the guide rod 12, thereby improving the structural safety and assembly flexibility. Example 3

[0026] Please see Figure 1-5 As shown in the figure, in this embodiment, a retractable cable tray for preventing cable displacement has several suspension rings 13 connected to both sides of the protective mesh cover 5. The suspension rings 13 are detachably connected to the side wall of the side cable tray 2. Specifically, by detachably connecting the suspension rings 13 to the side wall of the side cable tray 2, the suspension rings 13 on both sides of the protective mesh cover 5 are sleeved or fixed to the connection structure of the side cable tray 2, which facilitates the quick installation and removal of the protective mesh cover 5, thereby improving the convenience of maintenance, facilitating cable laying and subsequent inspection.

[0027] The side wall of the side cable tray 2 is fixedly connected with several connecting posts 10 that are adapted to the suspension ring 13. One end of the connecting post 10 is fixedly connected to a limiting circular plate 9. Specifically, by fixing the connecting post 10 to the side wall of the side cable tray 2 and setting the limiting circular plate 9 at its end, the suspension ring 13 is prevented from axially falling off after being sleeved on the connecting post 10, thus forming a stable connection. This achieves the effect of enhancing the installation firmness of the protective net cover 5 and preventing it from accidentally loosening.

[0028] When installing this retractable cable tray to prevent cable displacement, the entire tray system is first securely installed onto the wall or supporting structure using the mounting rods fixed at both ends of the bottom frame 1 and the mounting brackets 3 on them, completing the initial positioning. Then, according to the actual installation space requirements, the width of the two side trays 2 is adjusted. During the adjustment, the sliding rod 4 moves along the side wall of the bottom frame 1, and the sliding groove 8 on one side of it forms a sliding engagement with the guide rod 12 fixed to the side wall of the bottom frame 1, achieving smooth horizontal sliding of the sliding rod 4 and preventing skew or jamming. The top of the sliding rod 4 is detachably connected to the side tray 2 via several connecting screws 7, facilitating disassembly, assembly, and synchronous movement. After adjusting to the appropriate width, the positioning screw 6 is rotated, with one end threaded through the sliding rod 4.
