[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0031] A type of prefabricated cable tray sleeve that can be pre-embedded, such as Figure 1 As shown, it includes a frame 1, an upper connecting plate 2, and a lower connecting plate 3. The upper connecting plate 2 and the lower connecting plate 3 are respectively located above and below the frame 1. The back of the frame 1 is provided with mounting holes 4 (see reference). Figure 3 An adjusting rod 5 is provided inside the mounting hole 4 (see reference). Figure 3 The adjusting rod 5 is located outside the frame 1, and one end is fixedly connected to the adjusting part 6 (see reference). Figure 3 The adjusting rod 5 is connected to a gear 7 at one end inside the frame 1, and the part of the adjusting rod 5 outside the frame 1 is provided with external threads. A first nut 8 that matches the external threads is provided between the adjusting part 6 and the frame 1 (see reference). Figure 3 ),
[0032] The upper connecting plate 2 and the lower connecting plate 3 are respectively provided with rack 9 and rack 10 that mesh with gear 7. The frame 1 is provided with rectangular holes 11 on both the left and right sides. The upper connecting plate 2 and the lower connecting plate 3 are provided with screws 12 on the left and right end faces near the rectangular holes 11. The screws 12 pass through the rectangular holes 11 and the end of the screws 12 is provided with a second nut 13 that is compatible with the screws 12. The gear 7 can be driven to move by the knob adjustment part 6. The gear 7 then drives the rack 9 and rack 10, causing the upper connecting plate 2 and the lower connecting plate 3 to move away from or towards each other. After adjusting to the desired degree, tighten the first nut 8 to lock the gear 7, rack 9, and rack 10. Finally, tighten the second nut 13 to improve the connection stability between the structures. This allows for installation between cable trays on different floors within a wide range. All cable tray sleeves can be mass-produced according to common standard sizes, eliminating the need for on-site processing and improving construction efficiency. After the cable is laid, only sealing is required, eliminating the need for further wrapping and beautification, reducing procedures and costs. The adjustable upper connecting plate 2 and lower connecting plate 3 can be seamlessly connected to the cable tray according to the site conditions, improving the overall appearance.
[0033] like Figure 1As shown, a T-shaped groove 14 is provided on one side of the front of the frame 1, and sliders 15 that are adapted to the T-shaped groove 14 are provided on the end faces of the upper connecting plate 2 and the lower connecting plate 3 near the front of the frame 1. By setting the T-shaped groove 14 and sliders 15, not only is the structural stability between the frame 1 and the upper connecting plate 2 and the lower connecting plate 3 strengthened, but the connection strength between the frame 1 and the upper connecting plate 2 and the lower connecting plate 3 is also enhanced.
[0034] like Figure 2 As shown, both the upper connecting plate 2 and the lower connecting plate 3 are provided with limiting slide rails 16 on one end face near the inner side of the back of the frame 1 (reference). Figure 4 The top and bottom of the frame 1 are equipped with limiting blocks 17 that are adapted to the limiting slide rail 16 (see reference). Figure 4 By setting the limiting slide rail 16 and the limiting block 17, the limiting slide rail 16 and the limiting block 17 cooperate with each other to effectively limit the movement stroke of the upper connecting plate 2 and the lower connecting plate 3, thereby improving the stability and accuracy of the structure.
[0035] like Figure 2 As shown, the front and left and right end faces of the frame 1 are provided with fixed folding plates 18. By setting the fixed folding plates 18, the fixed folding plates 18 can be securely fixed to the template and truss floor slab.
[0036] like Figure 5 As shown, the front end face of the frame 1 is provided with several cup comb connection holes 19. By setting the cup comb connection holes 19, the cable tray outgoing lines can be directly led out through the pre-reserved cup comb connection holes 19, eliminating the need for mechanical drilling on the construction site and greatly reducing drilling costs.
[0037] like Figure 1 and Figure 7 As shown, a washer 20 is provided between the first nut 8 and the second nut 13 and the frame 1. By providing the washer 20, not only can the fastening effect be improved, but the connected parts can also be effectively protected to prevent loosening and leakage, and to ensure the stability and reliability of the connection.
[0038] The working process and beneficial effects of this utility model are as follows: When it is necessary to adjust the upper connecting plate 2 and the lower connecting plate 3, the gear 7 can be driven to move by the knob adjustment part 6. The gear 7 then drives the rack 9 and rack 10, causing the upper connecting plate 2 and the lower connecting plate 3 to move away from or towards each other. After adjusting to the required degree, tighten the first nut 8 to lock the gear 7, rack 9, and rack 10. Finally, tighten the second nut 13 to improve the connection stability between the structures. This allows for installation between cable trays on different floors within a wide range. All cable tray sleeves can be mass-produced according to commonly used standard sizes, eliminating the need for on-site processing and improving construction efficiency. After the cable laying is completed, only sealing is required, eliminating the need for further wrapping and beautification, reducing procedures and costs. The adjustable upper connecting plate 2 and lower connecting plate 3 can be seamlessly connected to the cable tray according to the site conditions, improving the overall appearance.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
