Description

Technical Field

[0001] This utility model relates to the field of cable bracket technology, and in particular to a cable bracket. Background Technology

[0002] Cables are wire products used to transmit electrical energy, information, and convert electromagnetic energy. When cables are laid in cable trenches and tunnels, cable hangers are generally used for fixation. This is to isolate the cable from the ground or wall to prevent external vibrations from directly affecting the cable, and to prevent water vapor evaporating from the ground from affecting the cable, thereby ensuring the stable operation of the cable.

[0003] Cable trays are modular support devices used for the safe and orderly laying and management of cables. Their main structure consists of beams, fixed supports, and connectors. During installation, the path needs to be planned, the supports fixed, and the trays assembled in sections. After the cables are laid, they are fixed by binding or clipping to ensure load distribution and avoid mechanical damage. Cable trays replace traditional direct burial by being laid overhead or along walls, significantly improving cable heat dissipation, maintenance convenience, and environmental adaptability. They take into account both safety standards and long-term economic benefits, and are a key infrastructure for the efficient operation of cable systems in complex scenarios.

[0004] In existing cable brackets, the brackets are usually fixed to a fixed bracket with bolts. When the height of the bracket needs to be adjusted in real time according to the cable installation requirements, it can only be installed by matching the bolts with the pre-set mounting holes on the fixed bracket. This means that the height of the bracket can only be adjusted at a few fixed positions, which is inconvenient to use. In addition, when adjusting the position of the bracket, the fastening bolts must be removed first before the height of the fixed bracket can be adjusted. This operation is cumbersome and time-consuming, increasing the workload of the staff in actual work. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the bolt connection between the bracket and the fixed support in the prior art results in a complicated and time-consuming process when adjusting the height of the bracket, and a cable bracket is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cable tray includes a U-shaped mounting frame with a support arm slidably mounted on it. A limiting rack is fixedly mounted on the mounting frame. The support arm has a mounting groove, and a locking plate is slidably mounted in the mounting groove. The locking plate has a slot that matches the protrusions on the limiting rack. When the locking plate engages with the limiting rack, the position of the support arm is fixed. The support arm is provided with an unlocking component for unlocking or fixing the position of the support arm.

[0007] To facilitate fixing or unlocking the support arm, preferably, the unlocking component includes a limiting hole on the support arm, an adjusting rod movably installed in the limiting hole, the adjusting rod passing through the support arm and the locking plate, a spring being installed in the mounting groove, with the two ends of the spring abutting against the locking plate and the mounting groove respectively, and when the adjusting rod moves, the locking plate engages or disengages from the limiting rack.

[0008] To facilitate unlocking the support arm, the ratio of the diameter length of the limiting hole to the tooth length of the limiting rack is 1.5:1. When the adjusting rod slides to the other end face of the limiting hole, the locking plate completely disengages from the limiting rack.

[0009] To facilitate the movement of the adjusting rod, the mounting bracket is further provided with symmetrical guide channels, and the adjusting rod passes through the guide channels, with both ends of the adjusting rod extending outward to the outside of the mounting plate.

[0010] To prevent the card plate from detaching from the support arm, preferably, a limiting groove is provided in the mounting groove, and a corresponding limiting block is provided on the card plate in the limiting groove to limit the movement distance of the card plate.

[0011] To improve the adjustment accuracy of the support arm, preferably, the distance between adjacent protrusions and adjacent slots on the limiting rack is set to 1cm.

[0012] Compared with the prior art, the present invention provides a cable tray with the following advantages: 1. The cable bracket uses a limiting rack and a locking plate in combination, which facilitates the adjustment of the bracket height according to the engagement of the protrusions and grooves of the limiting rack and the locking plate. This makes it convenient to use and avoids the problem of traditional brackets requiring installation according to bolt holes, making the bracket of this application easy to adjust in height.

[0013] 2. This cable bracket uses a combination of a limiting rack, a locking plate, and an unlocking component. The unlocking component disengages the locking plate from the limiting rack, thereby unlocking the support arm. This facilitates the adjustment of the support arm's height, avoiding the cumbersome and time-consuming height adjustment process caused by using bolts.

[0014] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model uses a limiting rack and a clamping plate to facilitate the adjustment of the height of the support arm according to the engagement of the protrusions and slots of the limiting rack and the clamping plate, thus avoiding the problem that traditional brackets only have a few fixed spaces for adjusting the position of the support arm.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Example: Reference Figures 1-4 A cable tray includes a U-shaped mounting frame 1, on which a support arm 2 is slidably mounted. A limiting rack 3 is fixedly mounted on the mounting frame 1. The support arm 2 is provided with a mounting groove 21, and a retaining plate 4 is slidably mounted in the mounting groove 21. A limiting groove 23 is provided in the mounting groove 21. The retaining plate 4 is provided with a corresponding limiting block 41 corresponding to the limiting groove 23 to limit the movement distance of the retaining plate 4, effectively preventing the retaining plate 4 from moving too far and detaching from the support arm 2. The retaining plate 4 is provided with a retaining slot, which interacts with the limiting rack. The teeth on the rack 3 are matched. When the clamping plate 4 meshes with the limiting rack 3, the position of the support arm 2 is fixed, which makes it easy to adjust the height of the support arm 2. The height of the support arm 2 can be adjusted according to the cable installation requirements. The support arm 2 is provided with an unlocking part for unlocking or fixing the position of the support arm 2. When the support arm 2 is unlocked, the support arm 2 can slide on the mounting bracket 1, which makes it easy to adjust the height of the support arm 2. This avoids the problem that traditional brackets need to be installed with corresponding bolt holes, which causes the support arm 2 to be able to switch between fixed positions for adjustment.

[0020] Specifically, by using the limiting rack 3 and the clamping plate 4 together, the height of the support arm 2 can be easily adjusted according to the engagement of the protrusions and grooves set in the limiting rack 3 and the clamping plate 4, which is convenient to use and avoids the problem of traditional brackets requiring installation according to bolt holes, making the support arm 2 of this application easy to adjust in height.

[0021] The unlocking mechanism includes a limiting hole 22 on the support arm 2, in which an adjusting rod 6 is movably installed. The adjusting rod 6 passes through the support arm 2 and the locking plate 4. A spring 5 is installed in the mounting groove 21, with both ends of the spring 5 abutting against the locking plate 4 and the mounting groove 21, respectively. When the adjusting rod 6 moves, the locking plate 4 engages or disengages from the limiting rack 3. When the adjusting rod 6 is pulled towards the support arm 2, the locking plate 4 disengages from the limiting rack 3. Conversely, after releasing the adjusting rod 6, the spring 5 rebounds and pushes the locking plate 4 towards the limiting rack 3, engaging the locking plate 4 with the limiting rack 3, thereby fixing the support arm 2. After unlocking, the support arm 2 can move freely on the mounting bracket 1 until the required installation height is reached. Then, the adjusting rod 6 can be released to lock the support arm 2, improving the efficiency of adjusting the height of the support arm 2.

[0022] Specifically, by using the limit rack 3, the locking plate 4 and the unlocking component together, the locking plate 4 is disengaged from the limit rack 3 by the unlocking component, thereby unlocking the support arm 2. This makes it easier to adjust the height of the support arm 2, avoiding the problem of cumbersome and time-consuming height adjustment steps caused by using bolts.

[0023] The ratio of the diameter length of the limiting hole 22 to the length of the protrusion of the limiting rack 3 is 1.5:1. When the adjusting rod 6 slides to the other end face of the limiting hole 22, the clamping plate 4 completely disengages from the limiting rack 3. The length of the limiting hole 22 is slightly longer than the length of the limiting rack 3, which facilitates the complete disengagement of the clamping plate 4 from the limiting rack 3 and avoids the situation where the clamping plate 4 does not completely disengage from the limiting rack 3 after the adjusting rod 6 is pulled.

[0024] The mounting bracket 1 is symmetrically provided with guide channels 7, and the adjusting rod 6 passes through the guide channels 7. Both ends of the adjusting rod 6 extend outward to the outside of the mounting plate. The width of the guide channel 7 is consistent with the length of the limiting hole 22, so that the adjusting rod 6 can move laterally within the guide channel 7 and avoid the problem of the adjusting rod 6 getting stuck.

[0025] The distance between adjacent teeth and adjacent slots on the limiting rack 3 is set to 1cm. By making the distance between adjacent teeth and adjacent slots equal, it is convenient for the card plate 4 and the limiting rack 3 to mesh after displacement. On the other hand, it is convenient to calculate the moving distance of the support arm 2 based on the number of exposed teeth after movement, which effectively improves the adjustment accuracy of the support arm 2.

[0026] In this invention, the mounting bracket 1 is first fixed to the cable trench wall using the mounting holes and expansion screws. Then, when adjusting the height of the support arm 2 during cable laying, the operator first grips both ends of the adjusting rod 6 and pulls it. This causes the adjusting rod 6 to move the clamping plate 4, which in turn compresses the spring 5, causing it to deform. When the adjusting rod 6 can no longer move beyond the limit hole 22, the clamping plate 4 completely disengages from the limit rack 3. Pulling the adjusting rod 6 up and down then moves the clamping plate 4, which in turn moves the support arm 2, thus adjusting its height. Once the desired height is reached, the adjusting rod 6 is released. The spring 5 then rebounds, pushing the clamping plate 4 to re-engage with the limit rack 3, securing the support arm 2. This effectively improves the adjustment efficiency of the support arm 2 and prevents reduced work efficiency due to disassembly and installation of bolts.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
