Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically to a steerable and adjustable cable tray. Background Technology

[0002] Cable trays, also known as cable supports or cable troughs, are devices composed of supports, brackets, and installation accessories. Their main function is to support cables, ensuring that cables are neatly arranged, safely, and easily maintained within buildings or facilities. Cable trays are typically made of metal or non-metal. Their structure includes a base, side plates, and covers, which can be flexibly combined as needed. Cable trays are widely used in various situations requiring the laying of large numbers of cables, such as the low-voltage systems in office buildings, shopping malls, and other commercial buildings. One important feature of cable trays is their ability to rotate and adjust cable direction.

[0003] For example, Chinese patent CN214674125U, entitled "A Cable Tray," includes a base plate, baffles on both sides of the base plate, and mounting plates on the sidewalls of the two baffles that are far apart from each other. The two mounting plates are parallel to the base plate, and the upper surface of the base plate has heat dissipation holes. A filter screen is provided at the bottom of the base plate, and the filter screen is detachably connected to the base plate. A fixing member is provided on the filter screen, and the filter screen is fixed relative to the base plate by the fixing member. The fixing member includes a fixing ring plate and fixing bolts. The circumferential sidewall of the filter screen is fixed to the circumferential sidewall of the fixing ring plate, and the fixing bolts are threaded through the fixing ring plate and threaded at corresponding positions on the base plate. The connection includes an assist hole on the upper surface of the base plate, into which an assist roller is rotatably connected. The rotation axis of the assist roller is perpendicular to the length direction of the cable. The top of the circumferential sidewall of the assist roller abuts against the bottom of the circumferential sidewall of the cable, and the bottom of the circumferential sidewall of the assist roller is flush with the bottom of the base plate. Both sidewalls of the base plate perpendicular to the cable laying direction are arc-shaped, and the protruding parts of the arcs are opposite to each other. The two sidewalls of the baffle perpendicular to the base plate are also arc-shaped, and the protruding parts of the arcs are opposite to each other. An assist plate is rotatably connected to both sidewalls of the baffle perpendicular to the base plate, and the rotation axis of the assist plate is perpendicular to the base plate.

[0004] While the existing technologies can enable the installation of cable trays, in practical use, cable trays are difficult to adjust in direction. Typically, cable trays are fixed in a straight line, making it difficult to install them at cable bends when a change in direction is required during cable laying, thus reducing their flexibility. Furthermore, it is difficult to isolate cables inside the cable tray. After installation, cables are usually fixed inside the tray, leading to contact between cables and mutual interference. Therefore, this does not meet current requirements. To address this, we propose a steerable and adjustable cable tray. Utility Model Content

[0005] The purpose of this utility model is to provide a steerable and adjustable cable tray to solve the problems mentioned in the background art, such as the difficulty in steerable adjustment of cable trays and the difficulty in isolating cables inside the cable tray.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steerable and adjustable cable tray, comprising a first support plate, a second support plate disposed on one side of the first support plate, a metal telescopic tube fixedly disposed between the first support plate and the second support plate, the two ends of the metal telescopic tube being connected to the first support plate and the second support plate respectively, and a fixing seat fixedly disposed above the front and rear ends of one side of the first support plate and above the front and rear ends of one side of the second support plate, wherein the fixing seat is provided with a through hole, the through hole having a through structure.

[0007] Preferably, a threaded rod is provided inside the through hole, one end of which extends to the outside of the fixed seat on the second support plate, and the other end of which extends to the outside of the fixed seat on the first support plate. A nut is provided on the outside of the other end of the threaded rod, and the nut is threadedly connected to the threaded rod and contacts the fixed seat on the first support plate.

[0008] Preferably, the front and rear ends of the first and second trays are provided with a plurality of sliding grooves. The sliding grooves are equidistantly distributed along the axial direction of the first and second trays, and the sliding grooves are open structures. An installation plate is provided inside the front and rear sliding grooves, and the installation plate slides in cooperation with the sliding grooves.

[0009] Preferably, a heat dissipation hole is provided in the middle of the mounting plate. The heat dissipation hole has a through structure. A base is provided at the upper end of the mounting plate. A positioning rod is fixedly provided at the lower end of the base. The lower end of the positioning rod extends into the heat dissipation hole.

[0010] Preferably, a partition is fixedly provided at the center of the upper end of the base. Threaded holes are provided on both sides of the base, inside the partition and inside the mounting plate. There are four threaded holes on the base and eight threaded holes on the mounting plate. The threaded holes on the base correspond to the threaded holes on the mounting plate. Bolts are provided inside the threaded holes on the base, and the lower ends of the bolts extend to the bottom of the mounting plate through the threaded holes on the mounting plate.

[0011] Preferably, both the first pallet and the second pallet are provided with a cover plate at their upper ends, and the cover plate is fixed to the first pallet and the second pallet respectively by rivets.

[0012] Preferably, the upper end of the cover plate and the lower ends of the first support plate and the second support plate are each provided with three air grilles. The air grilles are through-type structures and have a mesh structure inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model allows for the directional adjustment of the second support plate using a metal telescopic tube and a threaded rod. When the second support plate needs to be rotated, first rotate the nut so that it moves along the threaded rod until the nut is removed from the threaded rod. Then, pull the threaded rod out of the fixed seat. At this point, adjust the direction of the second support plate according to the specific construction requirements until the second support plate is in the appropriate position. Simultaneously, the metal telescopic tube is in the extended state. Then, place the cable inside the first and second support plates. At this point, the bent part of the cable is protected by the metal telescopic tube, thereby improving the flexibility of bridge erection.

[0015] 2. This utility model can isolate multiple cables using partitions and mounting plates. After the cable tray is installed, adjust the position of the partitions according to the actual number of cables. Then, align the positioning rod at the lower end of the partition with the opening of the heat dissipation hole and move the partition downward until the positioning rod enters the heat dissipation hole. At this time, the threaded hole on the base corresponds to the threaded hole on the mounting plate. Then, align the bolt with the opening of the threaded hole and rotate it. The bolt's external thread allows it to pass through the threaded hole and extend to the bottom of the mounting plate, thereby fixing the partition. Then, place the multiple cables in the partitions between the partitions to prevent the cables inside the cable tray from contacting each other, thereby improving the working performance of the cables.

[0016] 3. This utility model can improve the heat dissipation inside the first and second trays through heat dissipation holes and air grilles. When the cable is energized, the heat generated by the cable itself will cause the temperature inside the first and second trays to rise. At this time, the heat is dissipated through the air grilles on the first tray, second tray and cover plate, thereby reducing the temperature inside the first and second trays. At the same time, the heat dissipation holes reduce the contact area between the mounting base and the cable, avoiding heat accumulation at the contact point between the cable and the mounting base, thereby improving the heat dissipation effect.

[0022] 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.

[0023] Please see Figure 1-4 An embodiment of this utility model provides: a steerable and adjustable cable tray, including a first support plate 1, a second support plate 2 provided on one side of the first support plate 1, a metal telescopic tube 3 fixedly provided between the first support plate 1 and the second support plate 2, the two ends of the metal telescopic tube 3 being connected to the first support plate 1 and the second support plate 2 respectively, and a fixing seat 4 fixedly provided on the upper front and rear ends of one side of the first support plate 1 and the upper front and rear ends of one side of the second support plate 2, and a through hole 8 provided inside the fixing seat 4, the through hole 8 having a through structure.

[0024] When in use, if the second support plate 2 needs to be rotated and adjusted, first rotate the nut 6 so that the nut 6 moves on the threaded rod 5 through the thread until the nut 6 is removed from the threaded rod 5. Then pull the threaded rod 5 out of the fixed seat 4. At this time, adjust the direction of the second support plate 2 according to the specific construction requirements until the second support plate 2 is in a suitable position. At the same time, the metal telescopic tube 3 is in the extended state. Then place the cable inside the first support plate 1 and the second support plate 2. At this time, the bent part of the cable is protected by the metal telescopic tube 3.

[0025] Please see Figure 1 and Figure 2 A threaded rod 5 is provided inside the through hole 8. One end of the threaded rod 5 extends to the outside of the fixing seat 4 on the second support plate 2, and the other end of the threaded rod 5 extends to the outside of the fixing seat 4 on the first support plate 1. A nut 6 is provided on the outside of the other end of the threaded rod 5. The nut 6 is connected to the threaded rod 5 by threads, and the nut 6 contacts the fixing seat 4 on the first support plate 1, so that the first support plate 1 and the second support plate 2 can be kept stable by the threaded rod 5 and the fixing seat 4.

[0026] Please see Figure 2 and Figure 3The front and rear ends of the first tray 1 and the second tray 2 are provided with a number of sliding grooves 17. The sliding grooves 17 are equidistantly distributed along the axial direction of the first tray 1 and the second tray 2, and the sliding grooves 17 are open structures. The front and rear sliding grooves 17 are provided with mounting plates 9. The mounting plates 9 slide with the sliding grooves 17, which facilitates the avoidance of the cable from contacting the lower end of the first tray 1 and the second tray 2, thereby improving the heat dissipation effect of the cable.

[0027] Please see Figure 2 and Figure 4 A heat dissipation hole 10 is provided in the middle of the mounting plate 9. The heat dissipation hole 10 is a through structure. A base 14 is provided at the upper end of the mounting plate 9. A positioning rod 16 is fixedly provided at the lower end of the base 14. The lower end of the positioning rod 16 extends into the heat dissipation hole 10, so as to reduce the contact area between the cable and the mounting plate 9 through the heat dissipation hole 10.

[0028] Please see Figure 2 and Figure 3 A partition plate 12 is fixedly installed at the center of the upper end of the base 14. Threaded holes 11 are provided on both sides of the base 14, inside the partition plate 12 and inside the mounting plate 9. There are four threaded holes 11 on the base 14 and eight threaded holes 11 on the mounting plate 9. The threaded holes 11 on the base 14 correspond to the threaded holes 11 on the mounting plate 9. Bolts 13 are installed inside the threaded holes 11 on the base 14. The lower end of the bolts 13 extends to the bottom of the mounting plate 9 through the threaded holes 11 on the mounting plate 9, which facilitates the fixed installation of the partition plate 12 through the threaded holes 11 and the bolts 13.

[0029] Please see Figure 1 and Figure 3 The upper ends of the first tray 1 and the second tray 2 are each provided with a cover plate 15. The cover plate 15 is fixed to the first tray 1 and the second tray 2 respectively by rivets, so as to cover the openings of the first tray 1 and the second tray 2 through the cover plate 15.

[0030] Please see Figure 1 and Figure 3 The upper end of the cover plate 15 and the lower ends of the first tray 1 and the second tray 2 are each provided with three air grilles 7. The air grilles 7 are through-type structures and have a mesh structure inside. This facilitates the heat dissipation inside the first tray 1 and the second tray 2 through the air grilles 7. At the same time, the mesh structure of the air grilles 7 can prevent animals from entering the first tray 1 and the second tray 2 to gnaw on the cables.

[0031] Working principle: After the cable tray is installed, adjust the position of the partition 12 according to the actual number of cables. Then, align the positioning rod 16 at the lower end of the partition 12 with the opening of the heat dissipation hole 10 and move the partition 12 downward until the positioning rod 16 enters the heat dissipation hole 10. At this time, the threaded hole 11 on the base 14 corresponds to the threaded hole 11 on the mounting plate 9. Then, align the bolt 13 with the opening of the threaded hole 11 and rotate it. The bolt 13 passes through the threaded hole 11 through the thread on the outside and extends to the bottom of the mounting plate 9, thereby installing and fixing the partition 12. Then, place the multiple cables in the partitions between the partitions 12. When the cables are powered on, the heat generated by the cables will raise the temperature inside the first support plate 1 and the second support plate 2. At this time, the heat is dissipated through the air grid 7 on the first support plate 1, the second support plate 2 and the cover plate 15.
