Description

Technical Field

[0001] This application relates to the field of cable tray technology, and in particular to a cable tray structure. Background Technology

[0002] Cable trays are support systems made of metal or non-metal materials, used to lay power cables, communication cables, etc. in an orderly manner, and to carry, protect and manage the cables.

[0003] During the installation of cable trays, multiple trays are spliced ​​together to meet the cable length requirements. The commonly used splicing method is to install a connecting piece on both sides of the ends of two spliced ​​trays along the length of the tray, and then fix the connecting piece to the ends of the two trays with multiple bolts, thereby splicing and fixing the two adjacent trays. However, in the process of installing the connecting piece, multiple bolts need to be tightened one by one, which reduces the installation efficiency. Therefore, this application proposes a new technical solution. Utility Model Content

[0004] To improve installation efficiency, this application provides a cable tray structure.

[0005] This application provides a cable tray structure, which adopts the following technical solution:

[0006] A cable tray structure includes a cable tray frame, a cover plate disposed on the cable tray frame, and an installation accessory for splicing and fixing two adjacent cable trays. The installation accessory includes a fixing block, a plug-in block, and a limiting mechanism. The fixing block is fixedly connected to one end of the cable tray frame, and the plug-in block is fixedly connected to the other end of the cable tray frame. The fixing block has a plug-in slot for the plug-in block to pass through. The limiting mechanism is connected to the fixing block and the plug-in block and engages with the cover plate.

[0007] Optionally, the limiting mechanism includes two limiting rods, a connecting block, and a snap-fit ​​assembly detachably connected to the two limiting rods. The two limiting rods are respectively connected to both ends of the connecting block. Both the fixing block and the insertion block have through slots with vertical openings along the longitudinal direction. When the insertion block is inserted into the insertion slot, one of the limiting rods slides through the through slot of the fixing block, and the other limiting rod slides through the through slot of the insertion block. Snap-fit ​​blocks are fixedly connected to the two side edges of the cover plate, and the two snap-fit ​​blocks of two adjacent cover plates are spliced ​​together and snapped into the snap-fit ​​assembly.

[0008] Optionally, the snap-fit ​​assembly includes an assembly block detachably connected to the upper ends of the two limiting rods. The two ends of the assembly block are respectively provided with assembly grooves along the transverse direction. The opening direction of the assembly groove is perpendicular to the length direction of the cable tray frame. The cross-section of the assembly groove is T-shaped and opened at one end facing the cable tray frame. The upper end of the limiting rod is provided with a clearance groove along its circumference, allowing the upper end of the limiting rod to pass through the assembly groove. The assembly block is provided with a snap-fit ​​groove parallel to the opening direction of the assembly groove. Locking components are provided on the inner walls of both sides of the snap-fit ​​groove. The locking components are used to lock the two snap-fit ​​blocks that are spliced ​​together.

[0009] Optionally, the locking assembly includes a locking block and a spring. The inner walls on both sides of the slot are respectively provided with grooves. One end of the spring is fixedly connected to the bottom of the groove, and the other end of the spring is fixedly connected to the locking block. The two locking blocks are spliced ​​together and inserted into the slot. The two locking blocks are respectively provided with locking grooves for the locking block to engage on their opposite sides. The two sides of the end of the locking block that extends into the locking groove are both set with bevels.

[0010] Optionally, the limiting rod is rotatably connected to the connecting block, and a receiving groove is provided on the side wall of any one of the limiting rods. The limiting rod is rotatably connected to a positioning rod that can be embedded in the receiving groove. The positioning rod can be retracted into the receiving groove and passed through the through groove of the fixing block or the plug-in block together with the limiting rod. The side wall of the other limiting rod is provided with a positioning groove for the positioning rod to be engaged.

[0011] Optionally, the side of the connecting block extends toward the center of the cable tray frame, and the extension of the connecting block is supported on the bottom surface of two adjacent cable tray frames.

[0012] Optionally, magnets with opposite magnetic properties are fixedly embedded at both ends of the cover plate.

[0013] In summary, this application includes the following beneficial technical effects: when multiple cable tray frames are arranged and spliced ​​along their length, the insertion block of one cable tray frame can be inserted into the insertion slot of the fixing block on another cable tray frame. After the insertion block and the fixing block are relatively fixed by the limiting mechanism, they are then snapped together with the cover plate. This not only splices and fixes the two adjacent cable tray frames, but also locks the cover plates on the two adjacent cable tray frames together, improving the overall installation efficiency.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0020] This application discloses a cable tray structure.

[0021] Reference Figure 1 The cable tray structure includes a cable tray frame 1, a cover plate 11 disposed on the cable tray frame 1, and an installation accessory 2 for splicing and fixing two adjacent cable trays. In this embodiment, the cable tray frame 1 is a trough-type cable tray in the prior art. The structure of the cover plate 11 is adapted to the cable tray frame 1. As in the prior art, the cover plate 11 covers the upper opening of the cable tray frame 1 by sliding. Since the cover plate 11 and the cable tray frame 1 adopt the prior art, they will not be described in detail here.

[0022] Reference Figure 2 The installation accessory 2 includes a fixing block 3, a plug-in block 4, and a limiting mechanism 5. The fixing block 3 is fixed to one end of the cable tray frame 1. The fixing method can be that the fixing block 3 is pre-welded to the cable tray frame 1 at the factory. The plug-in block 4 is fixed to the end of the cable tray frame 1 opposite to the fixing block 3. The fixing block 3 has a plug-in groove along the transverse direction for the plug-in block 4 to pass through. The limiting mechanism 5 is connected to the fixing block 3 and the plug-in block 4 and is engaged with the cover plate 11.

[0023] With the above configuration, when multiple cable tray frames 1 are arranged and spliced ​​along their length, the insertion block 4 of one cable tray frame 1 can be inserted into the insertion slot of the fixing block 3 on another cable tray frame 1. After the insertion block 4 and the fixing block 3 are fixed relative to each other by the limiting mechanism 5, they are then snapped together with the cover plate 11. This not only splices and fixes the two adjacent cable tray frames 1, but also locks the cover plates 11 on the two adjacent cable tray frames 1 together, improving the overall installation efficiency.

[0024] Reference Figure 2 and Figure 3The limiting mechanism 5 includes two limiting rods 51, a connecting block 52, and a snap-fit ​​assembly 53 detachably connected to the two limiting rods 51. The two limiting rods 51 are respectively connected to both ends of the connecting block 52, and the two limiting rods 51 are vertically arranged. The fixing block 3 and the insertion block 4 are both provided with through slots 54 with vertical openings along the longitudinal direction. When two adjacent cable tray frames 1 are spliced ​​together, the insertion block 4 passes through the insertion slot. At this time, one of the limiting rods 51 slides through the through slot 54 of the fixing block 3. Another limiting rod 51 slides through the through slot 54 of the plug-in block 4. At this time, the connecting block 52 is located below the fixing block 3 and the plug-in block 4, and the side of the connecting block 52 extends towards the center of the cable tray frame 1. The extension of the connecting block 52 is supported by the bottom surface of the two adjacent cable tray frames 1, so that the height of the two limiting rods 51 can be kept consistent, which facilitates subsequent installation operations. Then, the cover plate 11 is installed, and then the snap-fit ​​assembly 53 is assembled on the two limiting rods 51. The two ends of the cover plate 11 are respectively fixed with snap-fit ​​blocks 6, so that when the two adjacent cable tray frames 1 are spliced ​​together, the snap-fit ​​blocks 6 of the two cover plates 11 can also be spliced ​​together and snapped into the snap-fit ​​assembly 53.

[0025] Reference Figure 2 and Figure 3 The snap-fit ​​assembly 53 includes an assembly block 531 detachably connected to the upper ends of the two limiting rods 51. Assembly slots 532 are respectively formed at both ends of the assembly block 531 along the transverse direction. The opening direction of the assembly slots 532 is perpendicular to the length direction of the cable tray frame 1. The assembly slots 532 have a T-shaped cross-section and are open at one end facing the cable tray frame 1. A clearance groove 533 is formed on the upper end of the limiting rod 51 along its circumference, allowing the upper end of the limiting rod 51 to pass through the assembly slot 532. After the two limiting rods 51 are respectively inserted into the two through slots 54, the operator can align the assembly slot 532 of the assembly block 531 with the clearance groove 533 of the limiting rod 51, and insert the upper end of the limiting rod 51 into the assembly slot 532 of the assembly block 531, thereby fixing the relative positions of the two limiting rods 51.

[0026] Reference Figure 3 and Figure 4 In addition, in order to relatively fix the assembly block 531 to the two adjacent cover plates 11, the following settings are made:

[0027] The assembly block 531 has a slot 534 parallel to the opening direction of the assembly groove 532. The slot 534 is located between the two assembly grooves 532. The inner walls on both sides of the slot 534 are respectively provided with locking components 7 for locking the two interlocking snap blocks 6.

[0028] Reference Figure 3 and Figure 4The locking assembly 7 includes a locking block 71 and a spring 72. Grooves 73 are respectively formed on the inner walls of both sides of the slot 534. One end of the spring 72 is fixedly connected to the bottom of the groove 73, and the other end of the spring 72 is fixedly connected to the locking block 71. The two edges of the locking block 71 facing away from the spring 72 are both beveled. When the cover plates 11 of two adjacent cable tray frames 1 are installed on the cable tray frame 1, the two snap-fit ​​blocks 6 on the adjacent cover plates 11 are spliced ​​together, and the spliced ​​structure can pass through the slot 534. Locking grooves 74 are respectively formed on the opposite sides of the two snap-fit ​​blocks 6 for the locking blocks 71 on both sides to snap into.

[0029] To ensure smoother insertion of the two snap-fit ​​blocks 6 into the slots 534 during splicing, the ends of the two cover plates 11 on adjacent cable tray frames 1 must be tightly fitted together. Therefore, magnets with opposite magnetic properties (not shown in the figure) are fixedly embedded at both ends of the cover plates 11. When installing the cover plates 11, ensure that the opposing magnets on adjacent cover plates 11 have opposite magnetic properties, allowing them to attract each other and tightly fit together. This ensures a stable splicing of the two snap-fit ​​blocks 6, and facilitates smooth... The two locking blocks 6 are inserted into the slot 534, so that the edges of the two locking blocks 6 abut against the inclined surfaces of the two locking blocks 71, causing the spring 72 to contract. During the movement of the two locking blocks 6, when the locking block 71 is aligned with the locking groove 74, the spring 72 drives the locking block 71 to engage in the locking groove 74, thereby fixing the assembly block 531 relative to the two adjacent cover plates 11. Furthermore, since both sides of the locking block 71 are provided with inclined surfaces, it is also convenient for the operator to disassemble the assembly block 531, which facilitates subsequent maintenance work on the cables inside the cable tray frame.

[0030] Considering that when the assembly block 531 is installed on the two limiting rods 51, the limiting rods 51 will move downwards due to gravity. In order to prevent the two limiting rods 51 from moving downwards, the operator must hold the connecting block 52 by hand before removing the assembly block 531. Based on the above, in order to facilitate the operator's installation of the assembly block 531, the following design is made:

[0031] Reference Figure 2Each limiting rod 51 has a vertically opening receiving groove 8 on its side wall. (In this embodiment, the receiving groove 8 is opened on the limiting rod 51 that passes through the fixing block 3.) The limiting rod 51 is hinged to a positioning rod 81 at the lower end of the receiving groove 8. The upper end of the positioning rod 81 can rotate outward so that the positioning rod 81 extends out of the receiving groove 8 as a whole, and can also rotate back into the receiving groove 8. When the positioning rod 81 is retracted into the receiving groove 8, it can pass through the through groove 54 of the fixing block 3 or the plug-in block 4 together with the limiting rod 51. Correspondingly, the side wall of the other limiting rod 51 has a horizontally opening positioning groove 82 for the positioning rod 81 to be engaged. In order to facilitate the positioning rod 81 to be snapped into the positioning groove 82, in this embodiment, the limiting rod 51 with the positioning rod 81 is rotatably connected to the connecting block 52 through a bearing. The other limiting rod 51 can also be rotatably connected to the connecting block 52 through a bearing, or it can be fixed on the connecting block 52, but the positioning groove 82 needs to be set in the direction of the positioning rod 81.

[0032] With the above setup, after the limiting rod 51 is inserted through the through groove 54, the positioning rod 81 is rotated outward. Then, by rotating the limiting rod 51, the limiting rod 51 drives the positioning rod 81 to rotate, so that the end of the positioning rod 81 rotates into the positioning groove 82, thereby playing a temporary limiting role, so that the limiting rod 51 can be located in the through groove 54, preventing the limiting rod 51 from moving downward out of the through groove 54. This makes it easy for the operator to directly insert the assembly block 531 into the upper end of the two limiting rods 51. During this process, the operator can simultaneously align the slot 534 of the assembly block 531 with the two snap-fit ​​blocks 6 and insert the two snap-fit ​​blocks 6 into the slot 534. At the same time, the upper ends of the two limiting rods 51 are also inserted into the receiving groove 8. This not only fixes the cover plate 11 to the cable tray frame 1, but also fixes and splices the two adjacent cable tray frames 1, thereby improving the overall installation efficiency.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
